Welcome Message

Local Host

Dr. Hiroshi Uechi

Faculty of Commerce

Osaka Gakuin University

Dear delegates,

It is my great pleasure to welcome you to the joint conference of Annual Conference on Engineering

and Applied Science (ACEAT), International Conference on Life Science and Biological Engineering

(LSBE), and Annual Conference on Management and Social Science (ACMASS) in Osaka, Japan,

which promotes exchanges of information, communications and collaborations among researchers

worldwide. The 21st century is the age of atomic and molecular science, and the age of exploration to

Mars and possibly to other planets using spacecraft technology. We gradually come to understand the

earth as the unique spacecraft in the universe, and we need collaborations not only from scientists but

also people with all expertise in order to resolve problems and sustain our societies and ecological

systems, energy resources, etc. The international conferences such as ACEAT, LSBE and ACMASS

would help mutual understandings and play more important and valuable roles in due course. Above

all, we would like to welcome all of you to the above conferences and also hope that every participant

will enjoy cultural explorations in Japan.

Yours sincerely,

Dr. Hiroshi Uechi

Nanostructured Metal Oxide Materials for Energy Storage

Dr. Kwun Nam Hui

Associate Professor

University of Macau

Abstract

With the rapid development of electronic technology, wearable and flexible devices such as roll-up

displays, biomedical sensors, and wearable devices, have drawn considerable attention. Developing high

energy density flexible supercapacitors (FSCs) hold the promise to provide a safe, fast charge/discharge

rate, and long-life flexible energy storage devices. To date, electrodes of high-performance FSCs are

mainly composed of carbonaceous materials such as carbon nanotube (CNT), graphene and

CNT/graphene hybrid due to their distinct properties of high conductivity and mechanical flexibility.

However, the CNT/graphene-based electric double-layer capacitor possesses low specific capacitance due

to its intrinsic double-layer charge storage mechanism, which relies on the electrostatic attraction of

electrolyte ions and charges at the electrode surface. Accordingly, hybridizing pseudocapacitive metal

oxide materials with carbon-based materials such as CNT and graphene has become an appealing strategy

in increasing the specific capacitance and energy density of film electrodes. In this talk, the speaker will

present his recent work in the development and application of nanostructured metal oxide electrode for

high-performance flexible supercapacitors. Several strategies, including the morphology control,

core/shell architecture, and defect engineering, will be discussed to improve the electron transports,

electrolyte ions diffusion kinetics, and electrical conductivity of metal oxide electrodes.

Topic:

Reviving the Engineers in Our Genes

Abstract

It can be said that the history of mankind is the history of engineering. Archaeology tells us that Homo

habilis, the oldest known human species who had the ability to create and use tools more than 2 million

years ago also developed a brain double the size of its predecessor who had started walking on two legs

another million years before. Evolutionary Psychology also tells us that engineering started when

evolution shaped what we call the engineering mind in our ancestors. Urge theory of Toda (1981)

postulated that human emotions evolved to survive in natural environments in which our ancestors lived

during most of the human history. An urge is a set of emotion and action that, upon encountering a certain

type of situations, ‘urges’ us to do certain actions that optimize our chance of survival in those situations.

Let us examine two types of urges that are relevant for the history of engineering.

Learning urges: emotions like curiosity and challenge which were essential for learning the skills and

knowledge necessary to make and use tools.

Social urges: helping urge giving the motivation to help others in need or contribution urge to do

something useful for the community.

These urges were the driving force behind the ancient engineering, inventing and improving many useful

tools. These mental functions were adaptations to the natural environments in which our nomadic

ancestors survived by hunting and gathering for millions of years. However, the engineering driven by

20

these urges has, by making new kinds of tools, changed the very environments in which they had evolved

to function. Some groups of homo sapiens started to engineer the environments when they invented

agriculture about several hundred thousand years ago which then spread to most other groups. Farming

forced them to shift from the nomadic lives with simple tools to settled lives with larger and more

complicated tools, creating houses, storages, villages, and weapons to protect them. Then only about a

few hundred years ago, less than 0.1% of the human history, engineers invented machines that used fossil

energies which led to the industrial revolution, changing our environments drastically and fundamentally.

When our environments change so rapidly, there is no time for our genes to properly adapt to them, and

these urges no longer function properly in our modern environments. For example, learning urges like

curiosity and challenge seem to work well in young children when they play with natural objects or

simple toys, but as they grow older and the tools and toys they use become more and more complicated, it

becomes more difficult to feel curious about their mechanisms or feel challenged to make the toys/tools

themselves. Social urges like help urge or contribute urge are difficult to function in modern

environments because the natural and human resources that support our daily lives have become invisible.

Thus, more and more people buy and consume things that are produced by people they never meet using

resources they never see, and those who produce things in factories never meet the users, and never know

where the materials and energies they use are from. Humans have created environments in which most

people are caught in what Ivan Illich (1973) called "radical monopoly" in which they have to rely on huge

systems that supply them foods, energy, health, and everything they need to survive in exchange of money,

which they must earn by keep working, rather than working together to help each other live. This

ignorance of the production processes has caused many global issues, such as environmental destruction,

inequality, and exploitation of poorer communities.

The history of engineering is so ironical: the engineering mind that was supposed to function in natural

environments actually have created environments that it cannot function well, thus making it more

difficult to do engineering with proper motivations and producing solutions that can address more

sustainable benefits rather than short-term gains. What can engineering do to fix this situation?

In our keynote presentation, we propose some directions for revising the engineer design process to try to

answer this question. This new process introduces stages including stakeholders identification and

evaluation, experience and roleplaying workshops as well as participatory design practice. With these new

stages, we hope the learning urges and social urges in our engineering minds could be revitalized, while

the objectives and engineering solutions could also be realigned to help yielding sustainable benefits. As a

result, it may help us to escape from this vicious cycle.

Narcissism and Antisocial Personality: Global Challenges for Business and

Beyond

Dr. Meg Milligan

Associate Professor

Troy University

Abstract

Narcissism refers to a set of characteristics that describe some individuals’ basic personality style, as well

as to a mental disorder called Narcissistic Personality Disorder (NPD). Narcissistic traits include

arrogance, self-centeredness, need for admiration, a sense of entitlement, interpersonal exploitation, and

lack of empathy. The term derives from the myth of Narcissus, who fell in love with his reflection in a

pool of water, and this led to his demise. Research indicates a trend toward increasing narcissism

worldwide.

The Diagnostic and Statistical Manual of Mental Disorders (DSM), the text used by mental health

providers as a basis for diagnosis, added NPD to its third edition in 1980. All subsequent editions list

NPD, including the most recent, the fifth edition, published in 2013. NPD is included in the World Health

Organization’s (WHO) international companion, the International Classification of Diseases, Tenth

Revision (1992), as well.

Narcissistic traits are prominent in other DSM personality disorders, most notably Borderline Personality

Disorder (BPD), depicted in the movie Fatal Attraction, and Antisocial Personality Disorder (ASPD), with

its salient psychopathic personality component, exemplified by Joseph Stalin of the Soviet Union, and

serial killers such as Ted Bundy in the U.S. The prototypical psychopath is a superficially charming,

impulsive, manipulative, remorseless, pathologically lying, male social predator with an inflated sense of

self. A synthesis called the Dark Triad, which describes a particularly dangerous type of personality,

focusses on psychopathy, narcissism, and Machiavellianism (deceitful, amoral, master manipulators).

Narcissism has a compelling fascination for a wide audience. Although the negative and destructive

aspects are obvious, such as its association with criminality, aggression and vengeance, there appear to be

22

some positive applications in certain contexts, such as productive narcissism, successful leadership if

these individuals are managed effectively, and positive organizational narcissism.

A resurgence of interest in narcissism accompanied President Trump’s election, the “narcissistic”

millennial generation’s ascendency, concerns about narcissism in politics and big business, and a general

trend toward globalization. Furthermore, data indicate increasing individualism, focusing on oneself

rather than group wellbeing, worldwide, with a corresponding decrease in collectivism, concern for the

common good.

Examples of business leaders with narcissistic tendencies include Andy Fastow, ex-CFO of Enron, who

contributed greatly to his company’s demise and spent six years in prison; Bernie Madoff who

orchestrated the most costly financial fraud in U.S. history; and Facebook founder, Mark Zuckerberg,

who faces backlash from data security breaches that affect millions of people worldwide. In addition,

collective narcissism, a belief that one’s group is superior to other groups and that others can be quashed,

first applied to Adolf Hitler, as well as the type of abnormal narcissism seen in ASPD, seem widely

applicable in today’s world.

It is clear that people with narcissistic and antisocial personality traits can present huge problems to

today’s businesses and beyond, whether these traits are in the normal range or not. My address (1)

describes narcissism and antisocial personality, (2) discusses the positives and negatives applied to

business and social issues, and (3) depicts the current and future challenges to international business and

global society presented by narcissistic and antisocial behavior, as well as some possible solutions.

The Controversial Portrait of the “Hero”: Saigo Takamori and His Sei-Kan Ron

in the Early 1870s

Dr. Mizuno Norihito

Professor

Akita International University

Abstract

It would not be an overstatement that Saigo Takamori is one of the most heroically or favorably described

historical figures in Japan today, for example, as Saigo has ever been picked up as the protagonist of

NHK’s year-long historical TV drama called Taiga drama twice, including this year. His dramatic life as

one of the primary contributors to the imperial restoration in the late 1860s and as the leader of the

anti-government armed uprising in the late 1870s and his personality has been attracting the Japanese.

However, in postwar Japan under the so-called pacifist constitution, it seems to be arduous to fit his

controversial proposal for Korea policy in 1873 into the popular image. The policy proposal called

Sei-Kan ron has become an issue among historians since the late 1970s. Inside and outside of academia,

there are conflicting two theories on his intent: some regard him as a jingoist advocating a military

solution to break through stagnated normalization talks with Korea, also expecting a war to materialize

his domestic and external objectives. Others contend, however, that Saigo sought for and was even

confident in settling the diplomatic trouble peacefully. This presentation does not find convincing grounds

to support the pacifist theory in which the postwar Japanese ethos would more affinity, and instead argues

that he never dropped the use of force as a policy option.

1. Background

Sludge as a by-product from wastewater treatment in the textile industry is increasing every year due to

the increasing need of traditional and modern clothing along with the increase of population in the world,

particularly in Indonesia. The polluted soils have negative impacts on agriculture production and human

health. The objective studies are to assess plant toxicity of the textile-sludge contaminated soils, and to

measure effect of adding citric acid as a natural chelating agent on Zn concentrations of the contaminated

soils, plant growth and Zn uptake by sunflower.

2. Results

The plant height of S0C0 was 67.2 cm significantly higher than the other treatments, which of S1C1 was

51.8 cm significantly higher than that of S1C0 and S1C2. Dry biomass distributions of root, stem, leaf

and flower were in the range of 8-15%, 36-49%, 22-25% and 19-29% of the total dry biomass,

respectively. Table 1 represent plant biomass (dry bases), Zn concentrations of soil and plant, and Zn

uptake of sunflower at 8 WAT. The highest total dry biomass was 5.1 mg/plant (S0C0) and not

significantly higher than that of S0C1, S0C1 and S1C1. Application of citric acid on S0 and S1 treatments

was suppressed plant height of 30% and 57%, and decreased dry biomass of 36% and 78% of the highest

total dry biomass, respectively. However, the treatment of S1C1 had the lowest plant height suppression

and biomass decrease of 23% and 33%, respectively. Concentrations of Zn on S0 treatments were tended

to decrease with increasing dose of citric acid, but Zn concentration of S1C1 was significantly higher than

that of S1C0. Similarly, Zn uptakes were not significantly decrease on S0 treatment, but significantly

higher on S1C1 than S1C0 and S1C2 treatments.

Abstract

Genetically engineered micro-organisms have been widely used for producing high added value

biomolecules such as pharmaceuticals, biofuels and natural products. To facilitate advancements in

biotechnology and synthetic biology, the CRISPR/Cas9 system was developed to become the most

effective and commonly used DNA engineering tool for gene activation, gene interference, gene

knock-out and knock-in. E. Coli and S. Cerevisiae are the two strains frequently used in research and

industries. Successful genomic editing of these stains with CRISPR/Cas9 provides great advantages when

studying a gene’s function as well as cell factory development. At Synbio Technologies, we utilized our

propriety Genotype-Phenotype-Synotype (“GPS”) platform build up an E. Coli gene editing platform that

successfully generates gene knock-in or knock-out in E. Coli genome. We have successfully engineered E.

Coli by introducing butanol synthase genes into its genome, resulting in a new strain expressing butanol.

Moreover, we also constructed a universal gene editing vector for S. Cerevisiae and Pichia. Using this

vector, the ADE1 gene of S. Cerevisiae was successfully knocked-out, which led to the inhibition of

adenine related synthesis pathway and accumulation of red pigment in cells, resulting in a “pink” S.

Cerevisiae strain. Using the same technique, another S. Cerevisiae strain was also engineered to stably

produce albumin by an insertion of a HindIII endonuclease site within the albumin denaturation gene

(YPS1). Through these experiments, we have displayed that the CRISPR/Cas9 system is remarkably

flexible and programmable for multiplexed gene editing and regulation in micro-organisms.

1. Background

Phosporotioate antisense oligonucleotides (ODNs) as a gene silencing of malarial Erythrocyte Binding

Agent (EBA) 175 and Deoxyhipusin Sintase (DHS) have shown to posses promising features an anti

malarial agents because of the rapid emergence of drug resistance all current drugs. To improve its

stability from nuclease degradation and increase cellular penetration, ODNs EBA 175 and ODNs DHS

were complexed with combination of three biomedical polymers namely chitosan (CS),

poly-lactic-co-glycolic acid (PLGA), and poloxamer. This study describes the formulation and process

modification to improve the nanoprecipitation technique, particularly to the physicochemicals and

morphology of ODNs polymeric nanoparticles. Furthermore, the principal objective was to explore the

influence of such modification on nanoparticle size.

2. Methods

Selected parameters on the nanoprecipitation method, such as the polymer ratio, rate and time of stirring,

were varied to obtain polymeric nanoparticles. The physicochemicals ODNs polymeric nanoparticles

were characterized by Dynamic Light Scattering measuring of particle size, polydispersity index and zeta

potentials. The morphology were characterized by Transmission Electron Miscroscopic (TEM).

3. Results

The results reveal that spherical nanoparticles with particle size less than 200 nm, the particle size

distribution in the range 0.3 – 0.5 and zeta potential approximately +27 mV were obtained in poloxamer –

PLGA ratio (10:1), 900 rpm and 2 h of stirring. The presented results demonstrate that nanoprecipitation

method in ODNs polymeric nanoparticle was affected by polymeric ratio, rate and time of stirring.

Abstract

Recent years, biological signals have attracted much attention as a tool of human interface.

Electromyogram (EMG) has been used in a variety of situations in particular. Generally, EMG in

muscular volume of arms or shoulders has been measured in many cases. In addition, expensive wet type

sensors have been often used. However, they are inconvenient and high-cost. On the other hand, in hand

motion recognition and personal authentication using wrist EMG, we have obtained good results.

However, accuracy is poor when hand motion recognition and personal authentication are carried out at

the same time. For the above reasons, we carry out hand motion recognition and personal authentication

at the same time, and try to obtain higher accuracy than the previous research. The conventional method

used EMG of movement Japanese Janken (Fig.1). We use a multi-input and multi-output model of a

Convolutional Neural Network (CNN). The average accuracy of hand motion recognition is 94.6%. The

average accuracy of personal authentication is 95.0%. In this paper, we use a Wide Residual Network

(WRN). The average accuracy of hand motion recognition is 97.8%. The average accuracy of personal

authentication is 98.4%. In future work, we aim to improve accuracy by adjusting WRN parameters. In

addition, we prepare a class not belonging to any class in multi-class classification.

Abstract

This article aims to evaluate the effects of number and position of mini dental implant (MDI) on stress

and strain distribution by performed three-dimensional Finite Element Analysis (FEA) in edentulous

mandibular and evaluate von Mises stress and maximum principal strain in different ten overdenture

conditions. Firstly, 3D part of edentulous mandibular was reconstructed from a computed tomography

(CT) analysis (Faculty of Dentistry Chiang Mai University) which were inserted by two, three, four and

five mini dental implants (MDIs) on different positions. Mini dental implant model and other components

were modelled analogous to real mini dental implant diameter 2.75 mm. After reconstruction procedure,

all components were processed to finite element analysis procedure (FEA). In FEA procedure all

components were assembled and assigned necessary mechanical properties. Load was applied 200 N on

posterior teeth (first molar) under bilateral condition. Stress and Strain were compared and analyzed by

multiple statistical procedure (Volume-average, Geometric mean) 1 mm in peri-implant area. Preliminary

results from FEA procedure von Mises stress and Maximum principle strain seem clearly interpret

relationship in number of mini dental implant and trends of stress and strain values. Therefore, the

volume average method was used to further explain this relationship. The result reveals that when number

of mini dental implant increased the stress and strain values tend to decrease 1 mm around peri-implant

area both cortical and cancellous bone. A gap between both stress and strain values decrease when mini

dental implant was inserted. From mini dental implant position perspective, the results showed both stress

and strain around in peri-implant area decrease when an implant position away from loading position. The

results of this study can conclude that number and position of mini dental implant significantly affects

stress and strain on peri-implant bone.

Abstract

The utilization of Accounting Information System (AIS) by the small, medium, and micro enterprises

(SMEs) at present is apparently at the minimum level if not to mention the integrated operation. This study

attempts to fathom and analyze, first, the impact of subsequently the system quality, the information

quality, the top management support upon the perceived usefulness. Second, the effect of the system quality,

the information quality, and the top management support on the end-user information satisfaction. Third,

how the perceived usefulness affects the end-user information satisfaction. Fourth, to analyze the effect of

the system quality, the information quality, and the top management support on end-user information

satisfaction via the perceived usefulness.

The study observed the designated SMEs managers in a chosen area of targeted location in East Java,

Abstract

Biological asset is a living animal and plant that have biological transformation. International Accounting

Standards Council (IASC) has published International Accounting Standard (IAS) 41 Agriculture which

regulates the biological assets, but its deemed inappropriate for accounting biological asset especially

animals owned by theme park, because recreational activity is not agricultural activity as there is no

management of the biological assets but simply control of the number of animals.

This research conducted at 3 (three) theme parks in Bali, Indonesia, with purpose to disclosure the

accounting treatment of biological asset owned by theme parks. The result shows that the first and second

theme parks use IAS 16 Property, Plant and Equipment as the basis of accounting treatment for biological

asset, while the third theme park uses IAS 38 Intangible Asset.

The first and second theme parks recognized their biological asset as Other Asset and measured value of

biological asset based on the cost of permit. The third theme park recognized their biological asset as

Property and Equipment and measured biological asset based on its estimation of cost of raising the

animal through estimated average life for its species.

Recommendation given is that theme parks specialized in zoological activity should report their

biological assets gained from exchanges with other theme park at acquisition cost. Animals born on the

theme parks should be recorded at the cost of raising the animals into adulthood. Accounting standard use

is the IAS 16.

Population Aging, Financial Availability and Housing Prices in China

Abstract

Previous studies show that population aging usually puts downwards pressure on house prices, however,

that is not the case of China. Based on the analysis of house prices rising, population aging, availability of

financial services and failure in optimizing the allocation of household assets in China, this paper

examines the role of financial availability in the relationship between population aging and housing price,

and offers a new explanation for the impact mechanism of China's population aging on housing prices.

First, a theoretical model is developed to study the interaction between population aging, financial

availability and housing prices in China. Then, using the prefectural panel data from 1999 to 2015 in

China, we carry out empirical test by adopting both static and dynamic models. The empirical results

show that in China, the effects of aging on house prices is highly depend on the availability of financial

services. When financial availability level is low, the aging has positive effects on housing price. With

increase access to financial services, the effects reserves. Our empirical results verify our theoretical

model in explaining why and how financial availability plays a role in the relationship between

population aging and housing prices. We argue that the insufficient financial availability leads to "a

shortage of financial asset ", which results in the contradiction between residents' large demand for assets

and insufficient supply in the financial market. As a result, China’s house prices continue to increase

because a large amount of funds pour into real estate market.

Abstract

Financial management is very important in a family to avoid financial problems of the family itself.

However, the capacity of low socioeconomic family understanding in managing family finances is

certainly not the same as an able family or a family with income above average exposure. This study aims

to explain thoroughly the model of low socioeconomic family financial management through the

perspective of street children mothers from Muntigunung, Tianyar Barat, Karangasem (informants),

relating to how to recognize and manage family finances, prioritizing home needs stairs, and income

allocation for savings.

This type of research is qualitative descriptive research with the process of collecting data through

participant observation, unstructured interviews, and documentation. Data analysis using interactive

model data analysis with three flow analysis, namely data condensation, data presentation (data display),

and conclusions or verification.

The result in general, informants do not understand how to properly manage finances. Their educational

and environmental limitations are classified as poor, encouraging them to prefer to borrow if they have

financial problems. If they get a salary, the meal will be used to pay the debt. But this debt process

continues every month and causes no desire to save (set aside income). Then, income is something that is

used to meet religious needs and family needs, debt is another way to meet needs (if income has run out),

while saving is not a solution to fulfill their needs.

1. Background

According to a 2015 assessment, the average flight in the region is currently delayed by 29 minutes and

this could reach 59 minutes by 2025 without action, due to air traffic control capacity and staffing issues.

Connectivity increases as the range of destinations increases, the frequency of service increases and/or

larger “hub” airport destinations are served. The trade-off between convenient connections and airport

congestion, showing that a higher layover cost leads an airline to reduce layover time by concentrating its

flights. In order to describe how airports’ on-time performance (OTP) relates to each other geographically,

we typically model an outcome variable that measures the airports’ on-time performance as a function of

the explanatory variable – connectivity, most commonly in a regression type of framework. When seeking

to establish the association in a regression model between the OTP score and connectivity, we implicitly

assume that the geographical or spatial locations of the observations in the analysis do not matter.

The study deals with the spatial dependence problem in linear regression analysis. This spatial patterning

– spatial autocorrelation – may be treated as useful information about unobserved influences, but it does

challenge the application of methods of statistical inference that assume the mutual independence of

observations. In addition to characteristics of individual airports, the infrastructure to support better

on-time performance in one airport are not independent of whether neighboring airports have better OTP

or not. We are suggesting that there is feedback among proximate airports that influences their

connectivity and OTP. What is the definition of neighboring airports? Are high connectivity levels

requisites for better OTP or worse OTP? What is the average value of OTP in the neighbors of the Kansai

International Airport (KIX)? Are these average values of neighboring observations correlated with each

airport's own score on OTP or connectivity?

2. Expected Results/ Conclusion/ Contribution

We have seen that the distribution of OTP displays spatial clustering in the sense that airports are more

likely to have higher values on the OTP score if they are surrounded by airports that also have high levels

of OTP. Although some of the clustering in OTP obviously could be due to spatial clustering in

connectivity, which in turn is positively related to OTP, we have shown that the spatial clustering in the

OTP data does not completely disappear when we condition on an airport’s level of connectivity. Given

that the distribution of OTP still displays spatial clustering after conditioning on an airport's connectivity,

we should look for possible ways to incorporate this spatial dependence in our previous regression model.

Abstract

Silicon (Si) nanostructures, in combination with one dimensionality and nanoscale features, have been

intensively studied for various applications. To engineer the Si nanostructures for practical devices, the

well controllability over dimensions and geometries has found to be essential, which is especially

applicable in fabricating the miniaturized devices and even bridging the realization of commercial

products. Herein, in this study, the controlled fabrication of nanostructured Si was demonstrated using the

wet chemical etching process, allowing the realization of diversified geometries of Si, such as nanopores,

nanobelts, straight/zigzag nanowires and others. These intriguing Si nanostructures enable different

properties from the bulk Si, including luminescent and photocatalytic characteristics, which will be

addressed in this talk. Moreover, we explored the impacts of texturized structures on the photovoltaic

performances of solar cells, and the results revealed the efficiency of nanostructure-based hybrid solar

cells could be improved by reducing the defective sites essentially arisen from the contact

non-uniformities between organic p-type layers and inorganic n-type nanostructures. Such hybrid designs

exhibited the improved conversion efficiency with 1.8 times greater than that of untexturized solar cells.

This approach allowed providing a unique opportunity for the understanding of nanoscale etching on

silicon which remained unclear from the existing techniques and related studies.

Abstract

In the thermal power plants, failure due to Type IV creep damage has occurred in high temperature steam

pipes made of Mod.9Cr-1Mo steel and a remaining life evaluation method is required. The purpose of this

research is to establish a simple method to estimate initiation rate, growth rate and initiation start time,

and to propose a new remaining life evaluation method. In this study, creep test is carried out with

notched test piece made of simulated fine grain heat affected zone (FGHAZ) of Mod.9Cr-1Mo steel.

Shape of test piece with high stress Triaxiality Factor (TF) that can be used in single axis creep test

machine was selected by FEM analysis. The damage test piece was observed with optical microscope.

The number density of voids with certain radius were measured. From them, the initiation rate of voids,

the growth rate of voids and the initiation start time of voids were calculated.

Affected Zone (FGHAZ) in the modified 9Cr-1Mo steel are intricately complicated immediately after

welding, but as the creep progresses, the recovery and recrystallization of the crystal grains proceed, the

grain size increases and the grain boundary become a simple shape close to a straight line. Although the

average grain size is an indication of recovery and recrystallization, it is a relative damage evaluation

because the initial value and the value at creep rupture are unknown. Therefore, we studied on using the

fractal dimension of grain boundary as an absolute indication. First, a creep test of a round bar specimen

having a notch was conducted to reproduce Type IV creep damage. We measured the fractal dimensions

at several different locations. Next, we obtained distribution of principal stress, von Mises stress, stress

triaxiality factor (TF) and creep strain of the test piece by FEM analysis. Then, the distribution of creep

damage was calculated with the time fraction rule. We compared fractal dimension with the maximum

principal stress, von Mise stress, triaxiality factor, creep strain and creep damage to confirm the

correlation between them.

1. Background

Diabetes mellitus has become one of the most significant health concerns in recent years [1]. Among them,

monitoring the daily blood glucose level has been considered an important issue of medical treatment of

diabetes. The above reasons illustrated the importance of development of analytical strategies for

detection of glucose with high sensitivity. In this study, we reported a facile green approach for the in situ

growth of silver nanoparticles (AgNPs) on the surfaces of carbon nanodots (CND). The AgNPs/CND

hybrid nanostructures possessed the ultrasensitive sensing capability of detecting glucose contents. It was

known that Glucose oxidase (GOx) could specifically catalysze the oxidation of glucose in the presence

of oxygen to form H2O2. We combined such reaction with the AgNPs/CND hybrid nanostructures for

providing the highly sensitive detection of glucose, and the sensitivity could reach at human blood

glucose level (4-7mM) [2].

2. Results

The result of H2O2 detection was illustrated in Figure 1(a), it showed that the absorption spectra of

AgNP/CND hybrid nanostructures could function as a sensitive detector for monitoring H2O2

concentration with the concentration range of 0-100 μM. The absorption band was noted at 400-410 nm, a

characteristic absorption of AgNPs due to the surface plasmon absorption. There was a phenomenon in

which the concentration of H2O2 and the characteristic absorption simultaneously decreased, as shown in

Figure 1(a). Moreover, a linear calibration line (R2 = 0.9846) was plotted by comparing the decrease of

absorbance (%) versus H2O2 concentration (μM). It was clearly shown that AgNP/CND hybrid was

ultrasensitive to H2O2 and it provided a recorded detection limit of 10 μM. The glucose detection was

illustrated in Figure 1(b), where it showed the absorption spectra of AgNPs/CND hybrid nanostructures

could efficiently detect the glucose detection with the concentration of 0-600 μM. The linear calibration

graph was achieved by plotting the decrease of absorbance (%) versus glucose concentration (μM) (R2 =

0.9233). It could be noted that the detection limit of glucose could reach 50 μM. The facile preparation of

AgNPs/CND hybrid featuring the highly sensitivity in detection of glucose was confirmed in this study.

*E-mail: syoon@skku.edu

1. Background/ Objectives and Goals

Timing offset estimation is one of the most important technical issues in orthogonal frequency division

multiplexing (OFDM) that has attracted much attention in various wireless applications, since a timing

estimation error could cause a severe signal-to-noise ratio (SNR) degradation. Although various timing

offset estimation schemes [1]-[3] have been proposed, [1] performs poorly under the influence of the

multipath fading, since one of the correlation peaks of the delayed paths can often be mistaken for the

correlation peak of the first path, and [2] and [3] presenting a threshold test and a normalization technique,

respectively, exhibit a serious degradation in performance when the first path suffers from severe

attenuation. In this paper, so, we propose a novel two-step OFDM timing offset estimation scheme: We

first obtain an initial estimate of the timing offset by finding a timing index maximizing an impulse-like

correlation function, and then, we estimate the timing offset by observing the statistical change of the

correlation function in the timing region around the initial estimate. Numerical results show that the

proposed timing offset estimation scheme offers an improvement in performance over the conventional

schemes.

2. Expected Results/ Conclusion/ Contribution

Fig. 2 shows the mean squared error (MSE) performances of the proposed and conventional schemes with

the following parameters: , the cyclic prefix length of 8, the carrier frequency offset of

0.1, and a multipath Rayleigh fading channel with an 8-path exponential power delay profile. From the

figure, the proposed scheme provides a better performance than those of the conventional schemes. This

is because the proposed method is based on the statistical information obtained from the multiple

correlation peaks, unlike the conventional methods employing the single correlation peak of the first path.

Abstract

In this study, the influence of illuminance and infrared on light sensors and color sensors used for

educational robots was examined. Main results obtained in this paper are as follows: (1) The light sensor

is susceptible to illuminance changes, and the higher the illuminance is, the more difficult it is to

distinguish between white and black colors. (2) It was confirmed that the color sensor cannot identify

colors correctly if it was irradiated with infrared at close range. The color sensor used in the experiment

identifies colors by frequency changes of reflected light from objects which irradiates from LED. (3) It

was experimentally verified that the influence of illuminance and infrared cannot be ignored in robot

competitions such as line trace. (4) The senior school teams which had received the education have won

national competitions in WRO fifteen years in a row and participated in international competitions in

WRO held in different countries on behalf of Japan. The senior school teams have won international

competitions in WRO eleven times up to the present. Students who had received the education to examine

the accuracy of the robot sensor obtained excellent results in the robot competitions.

Abstract

In a wireless communication system, frequency offset is one of the main problems and it should be

corrected at the receiver before the data processing algorithms applied to the received signal. Frequency

shift which is known as Carrier Frequency Offset (CFO) is generally introduced by the dynamic

environment conditions in the wireless communication channel. In this study, we proposed the

time-domain Cyclic Prefix based CFO estimation method and apply this method to the Filtered OFDM

(FOFDM) signal in the wireless channel. FOFDM is one of the good candidates for the next generation

5G communication systems. According to the simulations the received signal with the corrected CFO has

a good frequency synchronization and gives perfect Bit Error Rate (BER) results.

Abstract

Several student retention theorists have purported unique models to support First Year Engagement

theory. The scholarly contributions of Vincent Tinto (1993), Alexander Astin (1984), and Carol

Goodenow (1993) inform much of the literature. Astin (1984) provided an extensive foundation of

knowledge of the factors that contribute to academic and social engagement. Similarly, Tinto’s (1993)

research addresses the role of student engagement in relation to student persistence and Goodenow (1993)

discusses how a sense of belonging contributes to student success. However, with all this knowledge, first

year experience programs are not consistently achieving desirable results and colleges and universities

struggle to retain admitted students. This proposal utilizes the existing theoretical underpinnings

connected to first year experience to reveal the need for a more robust examination of the first year

experience and deeper investigation of factors that support and thwart student success and persistence and

ultimately propose the first comprehensive first year engagement theory.

1. Background/ Objectives and Goals

The internationalisation of research activities has been occurring relatively rapidly in the university

ecosystem. Addressing global sustainability issues is a part of strategies in enhancing international

research collaboration in universities. With significantly increasing awareness in polar (Antarctic and

Arctic) sustainability issues across the globe, along with the extensive history, and interest of international

research collaboration among universities and other higher education institutions - it is timely to explore

how regionally focussed scholarly endeavours, using the case of polar research, can contribute to a robust

foundation for the internationalisation dimension of a national higher education agenda.

2. Methods

This study implements qualitative research techniques, and operates at two analytical levels of analysis

which are internationalisation of university in the context of research, and the relative contribution of

tangible and intangible values from the polar research programme in the context of internationalisation.

3. Expected Results/ Conclusion/ Contribution

The key results of the study include exploring the importance of the international dimension of polar

research conducted in universities, by bringing to attention the values of mobility, co-authorship,

international network, global citizenship and knowledge diplomacy. This study sheds light on the theories

and lends a new body of fundamental social knowledge related to the internationalisation of research

strategies in university through polar research initiatives. Besides, this study explores a discipline more

thoroughly to generate specific hypotheses that can be tested in future empirical studies.

Abstract

In modern societies, education has become critical for both individuals and governments. From the

individuals’ perspective, education is not only critical in their seeking of jobs and attainment of social

status, but also is a key determinant of their personal success. From the governments’ perspective,

education produces professionals for the industries and nurtures leaders for the society. Given the rapid

development of the logistics industry in China and Hong Kong and the increasing demand for logistics

professionals with degree qualifications, the government, industry and education institutions are looking

for practical means to attract more logistics students below degree level to further their degree study,

thereby becoming logistics professionals. This paper reports a study that examined the factors

determining intention of logistics students below degree level to further their degree study using the

theory of reasoned action (TRA) model. A total of 81 logistics sub-degree students from a Hong Kong

university participated in the study. The results identified attitude, job security, aptitude and difficulty of

curriculum as important factors that determine logistics students’ decision to further their degree study.

Based on the findings, this paper offers some recommendations to the government, industry and

education institutions to encourage logistics students below degree level to further their degree study.

Abstract

The Information and Communication Technologies (ICT) are digital forms of communications. With the

fast-increasing transmission rate of Internet, the use of ICT in the daily activities of human life for all

sectors cannot be overemphasized. The Singapore government gives great recognition to the prominent

role ICT plays in education by allocating substantial fund to help all schools to set up good standard and

suitable educational technology settings. However, one of the most deciding factors to whether ICT can

be appropriately and effectively integrated into schools’ curriculum is teachers’ ICT skills beside their

subject content knowledge. In this study, we identify the required software, hardware, and support for

pre-school teachers. We also identify the ICT skills that pre-school teachers should have. This study used

questionnaire survey and interview to collect relevant information for the investigation.

1. Background

Superabsorbent gels as a three-dimensional network formed from both linear and branched polymers are

proficient of absorption and retention numerous kinds of liquids such as bodily fluids and blood solutions.

Recently, commercial superabsorbent gels are mainly produced from polymers derived from fossil as a

non-renewable and non-biologically degradable. Therefore, in this work, a novel superabsorbent gels

mainly produced from high purity and biodegradable polymer as bacterial cellulose (BC) was developed.

2. Methods

The preparation process of this superabsorbent gels was divided into 3 steps as a follow. Firstly, BC was

modified via carboxymethylation reaction to present carboxyl group onto their chains as carboxymethyl

bacterial cellulose (CMBC) in order to well disperse in the alkaline aqueous medium. Secondly, the

pendant group as double bond was then introduced where the CMBC was reacted with glycidyl

methacrylate (GMA). In the final, the superabsorbent gel was obtained when CMBC containing pendant

group was crosslinked with polyethylene glycol diacrylate (PEGDA) via radical polymerization in

alkaline aqueous solution. The the carboxyl group content, superabsorbent gel morphology and chemical

structure were then characterized by back titration, scanning electron microscopy and Fourier transform

infrared spectroscopy, respectively.

3. Results

We have successfully prepared superabsorbent gels using BC as the main component. It was found that

both the a carboxylic group content and crosslinker used influenced both the polymer network and water

retention value (WRV) of the superabsorbent hydrogels. The superabsorbent hydrogel with the optimal

condition of the use of crosslinking 5 wt% of CMBC-g-GMA with 2 wt% PEGDA represented the

eequilibrium WRV of 125 g/g hydrogel in distilled water at water absorption rate reaching 80% of the

total swelling capacity in 30 min. Due to the green nature of BC with inherent properties of high purity,

biodegradability and sustainability, the BC-based superabsorbent hydrogels may potentially find new uses

in hygiene, food, agricultural and pharmaceutical products.

1. Background

Heat storage materials have been attracted for a wide range of application such as air conditioning,

agriculture and textiles. The utilization of these materials was developed by the encapsulation. There are

many encapsulation techniques for the preparation of heat storage material microcapsule. The

microsuspension polymerization is one of the most popular techniques because of high encapsulation

efficiency. Therefore, in this work, it was then selected for microcapsule preparation. Some parameters

influenced on morphology and thermal properties of the encapsulated heat storage material were studied.

2. Methods

The methyl methacrylate (MMA)-based microcapsule encapsulated Rubitherm 27 (RT 27) used as heat

storage material was prepared by microsuspension polymerization. The solution of oil phase consisting of

MMA, crosslinked comonomer, benzoyl peroxide (initiator) and RT 27 was mixed with polyvinyl alcohol

aqueous solution. Thereafter, the mixture was homogenized to form monomer droplets dispersed in

aqueous phase. It was then polymerized at 80 C for 8 hours. The influence of crosslinked comonomer

type as ethylene glycol dimethacrylate (EGDMA), trimethylolpropane trimethacrylate (TRIM) and

divinylbenzene (DVB) on the microcapsule formation was investigated at various ratios of MMA:

crosslinked comonomer.

3. Results

In this study, three kinds of crosslinked comonomer as EGDMA, TRIM and DVB were used to

copolymerize with MMA as main monomer. In addition, various ratios (0:100, 30:70, 50:50, 70:30 and

100:0) of MMA: crosslinked comonomer were also studied. In the cases of MMA copolymerized with

EGDMA and TRIM, nonspherical microcapsules with low shell strength were formed. In contrast, using

MMA: DVB at 70:30 wt% exhibited the best result. The nonspherical microcapsule with high shell

strength was obtained. Furthermore, the latent heats of crystallization and melting of the encapsulated RT

27 were approximately 140 J/g-RT 27 closed to those of the original RT 27. The obtained copolymer

microcapsule with good thermal properties could be potentially used in various heat storage applications.

Abstract

Thermal batteries are operating temperatures using pyrotechnic heat pellet reaction melts the solid

electrolyte to activate the battery. To activate the battery, the heat pellets are ignited by heat paper. The

ignition process therefore depends on the combustion of the heat paper, which is sensitive to pyrolants

properties. Changes in these factors due to manufacturing variance, In this paper, we prepared metal

particles + metal oxide particles with energetic polymers as binder and investigated the characteristics of

heat papers such as calorimetric value and fabricated. Results show that during combustion, the

calorimetric value of Zr/BaCrO4 with nitrocellulose were increased. And the tape casting process can

have any desirable shape and size suitable for the operation. Therefore, the heat paper prepared were

stably ignited, burned and the combustion becomes efficient.

1. Background

Thermoplastic elastomers (TPE) typically classified into six generic classes of commercial TPEs;

Styrenic block copolymers(TPS), Thermoplastic polyolefin elastomers (TPO), Thermoplastic

Vulcanizates(TPV), Thermoplastic polyurethanes(TPU), Thermoplastic copolyester(TPC), Thermoplastic

polyamides(TPA) and Not classified thermoplastic elastomers(TPZ). The greener and higher performance

of TPE could be achieved by reinforcing with natural fiber. The flexural strength of TPU was enhanced

by adding the Hemp fiber [1]. The utilization of cellulose nanocrystals (CNCs) as a reinforcing material

in TPE was reported [2]. It was found that Tg and tensile strength was improved by adding CNCs.

Development of TPE reinforced with Kenaf fibre(KF) was also studied [3]. Two types of impact modifier,

thermoplastic natural rubber (TPNR) and polypropylene/ethylene propylene diene monomer (PP/EPDM),

were used. The present of KF and maleic has significantly increased the tensile strength of the PP/EPDM

composite while only less increment attained in TPNR system. In this work, the micro cellulose(MC) was

employed to reinforce the green TPC based on Poly(carbonate)(PC)/Poly(butylene succinate)(PBS)/

epoxidized natural rubber(ENR) blends. The mechanical enhancement without scarifying the elastomeric

characteristic was the main aimed.

2. Results

Table 1 summarizes the tested properties of green TPE/MC composites. With increasing the MC content,

the lost of impact strength but increasing in the tensile properties was observed. The tensile resilience

testing indicates the elastomeric characteristic of the green TPE composite.

At 40 g of MC in ERN compound, by increasing the ENR loading in the green TPE composite, it was

found that The impact strengths were in upright trend with good tensile elastic properties. The lost in

tensile properties due to the resilience tension load were minimal. ENR content at 100 g was

recommended for manufacturing the green TPE/MC composite. By employing the bentonite as

filler/colorant in the TPE manufacturing, it was found that the bentonite act as thixotropic filler. However,

it had no significant effect to the mechanical properties, especially tensile characteristics, of the TPE/MC

composite.

Fig. 2 show the selected SEM photos of PC/PBS blend and green TPE/MC composite at 60 g of MC

content, respectively. It is seen that there is no major phase separation between PC and PBS in the blend.

At 60 g of MC in the TPE matrix phase, it is visualized that the micro fiber is well dispersed in the matrix

phase. Also, good interfacial adhesion is apparently observed.

Abstract

The International Roughness Index (IRI) is the standard roughness index of pavement management

employed to acquire quantitative longitudinal surface-bump data of road profiles. It is a calibration of

road roughness measurement by using a quarter-car vehicle math model. The main purpose of this paper

is to closely examine correlations between the data profile of IRI and longitudinal surface-bump data and

explain mechanism in terms of physics by employing Lagrangian dynamical approach. The

conventional definitions and a new profile to define IRI is proposed.

Abstract

In real life, managers often have to face a variety of decision-making problems. Among them, the theme

of multi-criteria decision making (MCDM) is one of the most important and complex issues in the

decision-making field. In general, the elements of MCDM can be composed of three parts: input, output,

and solution. The input is expressed as m scenarios with n criteria. It usually assumes that the underlying

input data can be represented in a decision table. Accordingly, the output is the optimal result or set of

results that are resolved by different types of solution methods. In this study, we present a summary

technique that displays decision tables as new summary tables; allowing managers to make decisions

faster. The proposed technique is to optimize the results of the summarization, that is, to minimize the

loss of information. Since finding the minimum result is a NP-hard problem, we apply a genetic algorithm

to improve the summary results.

Abstract

In the regular work process of peer review, editors have to read and understand the entire set of

submissions to choose appropriate reviewers. However, due to a large number of submissions, to select

reviewers manually becomes error-prone and time-consuming. In this research, a framework that

considers different indispensable aspects such as topical relevance, topical authority and research interest

is presented and, an integer linear programming problem is formulated with practical considerations to

recommend reviewers for a group of submissions. Specifically, the topical relevance and the topical

authority are utilized to recommend relevant and accredited candidates in submission-related topics, while

the research interest is to exam the willingness of candidates to review a submission. To evaluate the

effectiveness of the proposed approach, categories of comparative experiments were conducted on two

large scholarly datasets. Experimental results demonstrate that, compared with benchmark approaches,

the proposed approach is capable to capture the research interest of reviewer candidates without a

significant loss in different evaluation metrics. Our work can be helpful for editors to invite matching

experts in peer review and highlight the necessity to uncover valuable information from big scholarly data

for expert selection.

Abstract

In this digital era, protecting secret data has been an essential factor. This protection can be done by

implementing various methods, such as data hiding. However, there are some problems in that scheme,

such as the limitation of the amount of the secret which can be protected. Indirectly, this relates to the

quality of the generated stego data. In this paper, we introduce the multiple peaks-based histogram

shifting method for protecting data. In this case, we divide the secret data according to the number of

corresponding peaks. The experimental result shows that the more peaks used for embedding data, the

more decrease the quality of stego data. However, this reduction is getting smoother along with the

increasing the number of peaks. Furthermore, we also find the optimum number of possible peaks to use

without much reducing the quality of the corresponding stego image.

Abstract

Due to the popularity of the Internet of Vehicles (IoV), many malicious packets may enter to the internal

network of a car from the Internet or telecommunication network. It is difficult to update the Internet of

Things (IoT) system into the newest version because most of IoT devices are low-powered and their

memory sizes are small. The hackers place the Trojans or backdoors through the known vulnerability by

scanning the system information. Therefore, our study focuses on the probing attacks and prevents such

situations. We provided a lightweight intrusion detection system with machine learning technology to

improve the detection of the malicious flows.

Abstract

In Educational Data Mining (EDM), classification is one of the crucial tasks to obtain a better education

environment. Support Vector Machine (SVM) has been among popular classification algorithms.

Nevertheless, there is still no further research about how to improve the performance of SVM. In this

paper, we focus on this issue. That is, how the enhancement of classification performance of SVM using

kernel selection on student’s cognitive domain should be performed. Here, kernel explored consists of

four kernels, namely: linear, polynomial, RBF and sigmoid. The experimental result indicates that the best

performance of SVM is achieved when linear (SVM_Linear) is applied whose accuracy level is about 84

%. On the contrary, the lowest of accuracy level is reached by polynomial (SVM_Polynomial), which is

about 63%. The other kernels: RBF (SVM_RBF) and sigmoid (SVM_Sigmoid) gain the same level of

accuracy, which is around 76%.

Abstract

Automatic Number Plate Recognition (ANPR) is an approach that adopts Optical Character Recognition

(OCR) and other image processing techniques (e.g., image segmentations and object detection) to read

vehicle registration plates. In order to get an efficient, smart and powerful system, ANPR software should

operate in real time. In recent years, the rapid increase in programmability of graphic processing units

(GPUs) has enabled us to get real time speed when implementing license plate segmentation. In order to

clarify the rate of time acceleration while observing the accuracy of the system, GPU techniques have

been widely used to obtain real time during implementing license plate segmentation, and to compare the

parallel system against the serial system. In this paper, an efficient algorithm has been presented to get all

advantages of License Plate Segmentation (LPS). More specifically, we propose a new methodology for a

powerful parallel OCR framework for LPS using GPUs with Compute Unified Device Architecture

(CUDA). Our proposed parallel GPU approach can be equally applied to Egyptian case and can also be

extended to cover more similar countries that employ the Arabic language. It is based on keeping the

names of these countries along with a list of Arabic characters as entries in a table; such these entries

could be matched parallel with the car plate.

Abstract

Tracking and detecting of moving object has obtained an eminent importance reason to impetuous

technological advancement in the field of computer science in Video Surveillance System. Human motion

is generally nonlinear and non-Gaussian and thus many algorithms are not suitable for tracking. One of

the applications to maintain universal security is crowd control. The main problem of video surveillance

is the ability of the monitoring officers with regard to crime detection. For security monitoring of live

surveillance systems, target identification and tracking strategies can automatically send warnings to

monitoring officers. In this paper we propose a robust tracking method to tracking the specific person and

detecting all human area in Video Surveillance System using the individual’s feature. The proposed

method to determine automatic detection and tracking combines Histogram of Oriented Gradient (HOG)

feature detection with a particle filter. The Histogram oriented Gradient features are applied for single

detection window for the identification humans area, after we use particle filters for robust specific people

tracking in the video surveillance systems by using colour and skin colour based on the characteristics of

a target individual. We have been improving the implementation, evaluation system of our proposed

methods. From our experimental results, we have achieved high accuracy detection rates and tracking

robust specific target objects.

Abstract

There are machine observation and human observation methods for the traffic volume survey problem.

However, it is difficult to classify car models because high accuracy machine classification is difficult.

The objective of this research is to classify car models and investigate traffic volume. In this method, we

detect a car from a moving image and use CNN to recognize it. We count the number of cars passing per

model and save the results in a CSV file. The recognition accuracy of the learning model used in this

method was about 59 %.

Abstract

Employers currently encounter more and more members of Generation Z - who finished their school as well

as university education - without knowing exactly what this generation wishes and needs. This paper

verifies current assumptions about Generation Z with a quantitative study, consisting of two parts. As a first

step, members of Generation Z (n = 103) were queried upon their work attitudes while in a second step,

company representatives (n = 48) were asked about their assumptions on the adolescents’ preferences.

Thus, not only conclusions on young adults could be drawn, but also on the (lack of) knowledge about

Generation Z of their employers. The prior assumption that the young generation would be difficult to

employ inter alia due to their refusal of a work-life blending, lacking career orientation, and inability to take

feedback could not be supported. In fact, Generation Z seems to be committed as well as motivated to work

for their professional success. Employers showed a decent understanding of their young employees, though

there seem to be a couple of misapprehensions.

Abstract

A manager makes inventory decisions based on inventory evaluation. There are two evaluation schemes.

One is end-of-period evaluation which assesses inventory periodically. The other is continuous evaluation

which calculates inventory-related cost as it accrues continuously over time. While it is known that

end-of-period evaluation leads to overstocks at the most downstream installation, it is not clear how it

affects an upstream installation. This paper compares decision-making under the two evaluation schemes

for a two-stage serial inventory system. It is found that end-of-period evaluation leads to overstocks at the

upstream installation as well. Thereafter, the consequence of mistakenly using end-of-period evaluation is

examined in terms of cost. This paper aims to discover a connection between results found under the two

evaluation schemes and facilitate a manger’s decision-making.

Abstract

Corporate Social Responsibility (CSR) is one of the most important corporate strategy for enhancing

competitive advantages and sustainable development of business. In the study, a case analysis and

in-depth interview were arranged with well-known international aviation corporate – Cathay Pacific; to

identify and evaluate the revised model on CSR practice in the sector.

In general, the interviewee provided valuable views and examples aligned with the revised model. The

findings would be helpful for filling the literature gap and provides a foundation for further studies of

CSR practices in other sectors / industries. The limitation of this research is that it only focuses on

qualitative research (i.e. personal interview and case study). Future research should be applied with

quantitative approach using a large sample of companies in order to generalize results.

Abstract

Based on an online questionnaire survey targeting at employed people from more than 10 provinces of

China, this paper investigates the distribution of hours mismatch among different social classes, trying to

give answers to two questions: which class is more overworked? How to reduce the sense of being

overworked with different kinds of job rewards, and whether the influences of job rewards differ in social

status? We find that although middle-class people are more likely to feel overworked, they have the

smallest hours mismatch; people at the lower status suffer the greatest discrepancy between actual and

preferred hours; the effects of both intrinsic and extrinsic rewards decline when social status moves up;

organizational efficiency as a kind of rewards makes elite people feel more overworked.

Abstract

Empirical studies of social network analysis have provided sufficient evidence to support the general

claim that high-centrality individuals in social networks outperform those with low centrality. We device

arguments from theories to question this claims and identify the needs for taking reversed causality into

consideration when examining the centrality-performance relationship. It is puzzling that previous studies

have assume causality only in one direction from centrality to performance, but not the reverse. The

possible origins of the endogeneity are discussed. Furthermore, the study reexamine the

centrality-performance relationship in the context of movie directors’ networks and box-office

performance. Our findings show that all measures of centrality significantly affect the outcome variable

when the method of instrumental variables is applied to address the proposed reversed causality.

Abstract

The number of street food vendors in Indonesia is enormous. Many of them sell their products on

semi-permanent stalls, while others moving around the residential area with their food cart. It is widely

known that sometimes their food hygiene is questionable. This study aims to acquire the knowledge level

of those street food vendors about food safety practices. The study was conducted in Bandung,

questionnaires were given to 300 respondents who were street food vendors. They were spread in three

areas where street food vendors were concentrated in bandung. After the data were collected They were

analyzed descriptively. The result showed that street food vendors still not aware of some important

knowledge related to food safety. It is proven that they have already known common knowledge about

food safety practices. However, they still need to improve more advanced knowledge in regarding food

safety practices. One of the most important findings of this study is that their knowledge about

government regulations of food safety is relatively low. This study is expected could become one of the

references for the government to give training and education program for street food vendors.

1. Background

Obstacles detection and avoiding abilities are very critical to achieving autonomous flight for commercial

unmanned aerial vehicles that have been widely applied to various applications, such as inspection,

surveillance and transport. There are some commonly-used approaches, like infrared, ultrasonic and

vision-based methods, for detecting and localizing obstacles in a real space, but all of them are with

disadvantages while being employed outside. Therefore, this study introduces a monocular vision based

depth sensing system by combining deep learning and LiDAR technologies.

2. Results

A great quantities of image correspondences that captured from a ZED camera are first collected to be the

dataset of training and testing. In order to compute the depth from disparity, the camera calibration is

necessary for obtaining intrinsic and extrinsic parameters. Thus the depth can be easily calculated by the

disparity, focal length and stereo baseline. However, a low-cost camera is only used in our application

scenario and there is no baseline in our work. A function of transforming disparity to depth must be

urgently needed. Here, a simple linear regression model is employed, where the disparity values are

estimated and the depth values are from a laser ranger finder, respectively. Fig. 2 shows the linear

regression curve. In the experiments, we have implemented the proposed system on an embedded

platform, as shown in Fig. 3, which contains the flight controller, Raspberry Pi, a camera, a LiDAR lite,

and a neural computing stick. Fig. 4 shows the depth sensing results, where the left image is the original

captured image on a drone and the right one is the estimated depth.

1. Background

Crinum thaianum (water-onion) is a native aquatic plant in the south of Thailand. It is in the family

Amaryllidaceae. Its leaves are extremely tough, making it suitable for aquariums with large fish.

Water-onion during blooming season in Ranong and Phangnga Provinces used to be a tourist attraction

site many years ago. At present it is classified as an endanger species due to the illegal digging for

exportation and the upstream destruction. These practices can lead to the reduction of water-onions.

No genetic information on water-onion has been reported. It will be good to have genetic information of

this endanger native species of Thailand for species specific identification and for evaluation of genetic

variations for conservation practices and sustainable uses.

2. Methods

Microsatellite (MS) markers were developed from the enrichment genomic library of water-onion. The

usable markers were used for genotyping of all water-onion samples. Moreover, DNA sequencing of

water-onion were performed at the ITS of rDNA (nuclear-encoded) and rbcL, matK, trnH-psbA intergenic

spacer (plastid-encoded) regions. The sequences were compared to the other crinum plants used as out

groups.

3. Results

Fifteen out of 28 MS markers were successful in amplification the specific target. DNA sequences in each

region were generated in out groups and 5 samples of water-onions collected from different locations in

Ranong and Phangnga Provinces. Crinum thaianum samples are still grouped together even though they

are in different locations. Therefore these four regions can be used as a marker to classify Crinum

thaianum from Crinum plants. For the future works, more MS markers will be developed. The

information obtained will be useful for specific identification of water-onion, the endanger species.

1. Background

Sensors are devices that respond to chemical, physical and biological stimuli, resulting in the production

of a signal that provides a quantitative measurement of the stimuli. We need sensors for monitoring

structural integrity of reactor containment buildings and nuclear waste repository, control of nuclear

power plants, pollution monitoring and leakages of toxic gases/chemicals[1-2]. The main objective of the

present work is to develop ion selective electrode sensors based on PVC membrane by incorporating

Schiff base ligands and their complexes, macrocyclic ligands as ionophores for sensing different metal

ions. Ion selective electrodes have been prepared and the electrodes performance was optimized by

varying the amounts of PVC, plasticizers and cation/anion excluders. Various characteristic features of

these proposed chemical sensors with different parameters such as response time, selectivity, lifetime and

pH effect on sensor response have been studied. The semicarbazide and thiosemicarbazide based Schiff

base ligands and their metal complexes have been synthesised and used for the fabrication of

electrochemical sensors or ion- selective electrodes. The proposed ISEs were successfully applied for the

determination of various cations and anions in water samples and also as an indicator electrode in

potentiometric titrations.

2. Results

The response of different metal ions and rare earth ions were plotted as the negative log of concentration

and the potential values obtained for different metal ions. The different membrane ingredients, such as

amount of ionophore, amount and nature of the plasticizer and additives influence the potentiometric

response behaviour of the sensor [7, 8]. The proposed electrochemical sensor exhibits a fixed membrane

composition and can be used to determine Pb2+

ion concentration in solution. The electrode works well in

a relatively wide, independent pH range and exhibits a fast response time, high sensitivity and selectivity

for Pb2+

ions. The life time of the electrode was 8 weeks. The proposed electrode was successfully applied

to the determination of lead in water samples by indirect potentiometry.

Abstract

The objective of this research is to apply the artificial neural network method to forecast the demand for

alum and chlorine, which are the main chemicals used in the water treatment process of Bangkhen water

treatment plant. The forecasting models are developed from monthly chemical consumption amount data

from October 2008 to September 2015 to forecast the monthly chemical demand amount during October

2015 to September 2016. Turbidity, dissolved oxygen, oxygen consumed, conductivity and pH are used as

the input variables of the models and selected by stepwise regression. The results show that the

appropriate structure for the artificial neural network, which provides the minimum forecast error for

alum, is one hidden layer with a number of neurons in the hidden layer – the output layer equals to 20–1.

The corresponding transfer functions are purelin–logsig. For chlorine, the proper structure is one hidden

layer with a number of neurons in the hidden layer – the output layer equals to 15–1. The corresponding

transfer functions are purelin–logsig. The mean absolute percentage errors of the alum and chlorine

demand forecasts are 18.27% and 14.70%, respectively.

Abstract

As stated by the expansion of the railway systems in Thailand, a great demand of construction material

especially rock aggregates, flows into the market so that the development of new material resources must

be precipitated. Chiang Mai, Thailand, contains the natural resources with high potential in developing as

material reserves for supporting raw material for railway construction, thus the investigation of the actual

resources has not been verified. In order to complement this desideratum, the combination of field

observation and geological technologies were a ubiquity for the investigation of these earth resources.

Conversely, in unapproachable area such as mountainous, the investigation using those techniques were

limited. To overwhelm those obstacles, the integrated remote sensing approach using the combination

between the observed spectrum of specific outcrop from spectrometer, Spectral Angle Mapper (SAM) and

the NDVI analysis were applied to locate the potential igneous rock outcrop within the region of Chiang

Mai, so that the further on-field investigation will consumes shorter period by straightly forwarding to

investigate the possible area. According to the study’s result, the appropriate SAM angle in classification

of biotite-hornblende granite outcrop in the inspected area were determined to be 0.35 radian with totally

3.66 km2 of the scattered potential area.

E-mail: kcju@isu.edu.tw

1. Background

The use of Low Intensity Pulsed Ultrasound (LIPUS) has demonstrated promising effects on articular

cartilage, especially on chondrocytes in knee osteoarthritis. However, fewer studies investigate what

extent LIPUS propagate within the knee joint space. The purpose of this study is to evaluate the

propagation properties of ultrasound over a simplified joint space model by using computer simulations.

2. Methods

The 2D computer simulations incorporate a reference model, which mimics the structure of the joint of a

human knee from a lateral view of CT image. All the simulations were performed using k-Wave, which is

an open source acoustics toolbox for MATLAB. It is designed for time domain acoustic and ultrasound

simulations. k-Wave allows the user to specify acoustic parameters, such as sound speed and density of

the medium and any acoustic source in the medium. The ultrasound transducer was modeled as a 2.0 cm

line source, which produced a 1.0 MHz ultrasound pulse. The ultrasound source was located at about 20

mm from the medial condyle. The effects of ultrasound transducer in different positions in height

direction were examined.

3. Results and Conclusion

Simulation results showed that ultrasound is capable to propagate through the simplified knee joint space

model. The amplitude of ultrasound pulse is decreased from the anterior to the posterior region of the

joint space. The amplitude of ultrasound pulse is also related to the position of ultrasound source in height

direction. Although the simulation model of this study has a considerable simplification, it is a start of

investigating the properties of ultrasound propagation in the joint space. The next stage of this study will

take into account for the heterogeneities of the articular bone structure.

1. Background

Fluorescent viscosity sensors – molecular rotors – provide one of the most convenient ways for

measuring viscosity in aerosols, model membranes and living cells.1 However, despite the increasing

usage of molecular rotors, the relation between their molecular structure and sensitivity to viscosity or to

other parameters, such as temperature and properties of the solvent is not well examined. We have

attempted to vary the molecular structure of BODIPY-C10 (Figure 1A) – one of the most popular

molecular rotors – and see how this impacts the sensitivity of the molecular rotor to viscosity, temperature

and solvent properties.2

2. Results

In this work we varied the substituents on the BODIPY-type molecular rotor, starting with heavy

electron-withdrawing –NO2 group, to electron donating –NMe2 group. The structures are shown in Figure

1B. Since BODIPY-type rotors are used to sense viscosity via their fluorescence lifetime, we have

measured the lifetimes of new BODIPY rotors at varying viscosities, temperatures and in different solvent

mixtures.

The rotor with no group (Figure 1B, middle) possessed very similar viscosity sensitivity properties to

BODIPY-C10; its viscosity-sensitive range is approximately 10 cP to 1000 cP, the time-resolved

fluorescence decays are shown in Figure 1C. In contrast, the rotor with –NMe2 group (Figure 1B, right)

was non-fluorescent. However, the rotor with –NO2 was not only fluorescent and viscosity sensitive, but

its viscosity sensitive range extended up to 50 000 cP, which makes it much more suitable viscosity probe

for high viscosity environments than BODIPY-C10. To our knowledge, this is the first fluorophore capable

of viscosity sensing in such viscous environments. Overall, this is an interesting example showing how

relatively small changes in molecular structure of molecular rotors can drastically change their properties.

1. Background

Waste generated from cattle farms is in the form of feces and cow urine. Every kilogram of milk

produced by dairy cattle produces 2 kg of cow solid waste (Sihombing, 2000). The amount of feces and

urine produced reaches 10% of the weight of livestock (Rinekso et al, 2011). Maximum capacity of PT.

Greenfields Indonesia, which reaches 10,000 cows, can produce 45 million liters of milk will produce

waste with a large enough quantity. If there is no good management of the cattle farm waste, it is feared

that there will be environmental pollution or other environmental problems that will have an impact on

human health and comfort around the area. Cow manure contains N (2.0%), P (1.5%), K (2.0%), Ca

(4.0%), Mg (1.0%) and S (0.5%) (Agricultural Research and Development Agency, 2013), and cow urine

contains up to 4.0% organic matter (Hartatik & Widyowati, 2006). These ingredients can still be used as

nutrients or plant nutrients by applying them as organic fertilizer. The objectives of this research are (1) to

determine the influence of liquid waste and solid livestock density as fertilizer on soil quality (2) to

determine the effect of liquid fertilizer on coffee plant growth (3) to determine the effect of solid fertilizer

on the growth of coffee plants.

2. Results

The results of the study showed that (1) the provision of cattle farm wastewater 1 time can improve the

C-organic chemical properties, N. total, P, CEC, Ca and Mg, while the soil chemical properties of pH, K,

Na, the amount of base and saturation of the base decreased . The C / N and Ca ratio parameters did not

change in the treatment of organic wastewater treatment once. Treatment of livestock liquid fertilizer 2

times can improve soil chemical properties pH, N total, Ca, Mg and saturation bases, while other

chemical properties of C organic, C / N ratio, P, CEC, K, Na, and base amount decline. Giving solid

waste of cattle farms 1 time can increase chemical properties of pH, C organic, N total, Ca and saturation

of base, while the soil chemical properties C / N ratio, P, KTK, K, Na, Mg and base amount decreased.

The treatment of the provision of livestock solid waste 2 times can improve the soil chemical properties

of pH, N. total, P, Ca, Mg, base number and base saturation, while other organic C. chemical properties,

C / N ratio, CEC, K and Na decrease (2) Provision of liquid waste fertilizer has a significant effect on

plant height and high rate of coffee plants (3) Provision of solid waste (compost) has a significant effect

on plant height, plant height velocity and number of buds.

Effects of Exogenous Hydrogen Peroxide in Rice (Oryza Sativa L.) Seedlings Under

Drought Stress

Weeraphorn Jira-anunkul, Wattana Pattanagul

Department of Biology Faculty of Science Khon Kaen University, Khon Kaen, Thailand

E-mail: weerahorn_j@kkumail.com

1. Background

Rice is an important staple crop for billions of people. However, the cultivation usually exposed to

drought stress which is the factor that limited plant growth. The previous evidence suggested that the low

concentration of hydrogen peroxide (H2O2) plays an important role in abiotic stresses. It regulates the

antioxidant system and the other drought tolerance mechanism via ABA signaling (Saxena et al., 2016).

Although the studies about the effects of H2O2 on drought tolerance related to physiological

characteristics were well-established; however, various concentrations of H2O2 were used and the suitable

concentration for rice is not reported. Therefore, this study aimed to investigate the effects of different

concentrations of H2O2 on the physiological characteristic related to drought tolerance by foliar spray

method.

2. Results

Rice seedlings exposed to drought stress dramatically decreased RWC and total chlorophyll content but

increased EL and MDA content compared to the seedlings under well water condition. Foliar spray with

H2O2 benefits to rice seedlings by improving several physiological characteristics. It is well-known that

H2O2 act as the signaling molecule under drought stress, many mechanisms related to drought tolerance

are activated during this condition including enzymatic-antioxidant system and abscisic acid signaling.

The main antioxidant enzymes including SOD and CAT were induced under drought stress in order to

remove the reactive oxygen species. Foliar spraying with all concentration of H2O2 tended to increase

these enzymes activities compared to distilled water spraying. The similar trend was found in MDA

content and EL, the results indicated that H2O2 spraying slightly decreased the oxidative damage

compared to distilled water treatment. In addition, the advantage in improving total chlorophyll content

was found in 1-2 mM of H2O2 spraying compared to distilled water group. In summary, H2O2 plays a vital

role during drought stress by enhancing antioxidant system as well as maintaining the water content. H2O2

is involved in ABA signaling which is related to stomatal closure. This may help H2O2 treated seedlings

maintaining higher RWC. As a result, higher antioxidant enzymes activities were higher in H2O2 treated

group; moreover, the reduction of EL and MDA were observed. The results from this study indicated that

the most effective H2O2 concentration in this study was 1 mM.

Effects of Melatonin on Growth, Some Physiological Characteristics and Antioxidant

Enzyme Activities in Rice Seedling Under Drought Stress

Department of Biology, Faculty of Science, Khon Kaen University, Thailand

E-mail: namtan_mizz@hotmail.com

1. Background

In Thailand, rice (Oryza sativa L.) is one of the most important crops. It is a widely cultivated staple food

that is exported worldwide (Siriphollakul et al., 2017). However, the cultivation usually exposed to

drought stress which is the factor limiting plant growth. Many recent studies found that plant growth

regulators are extensively used to regulate plant growth and to enhance plant drought stress tolerance.

Melatonin is a biological hormone involved in many important physiological processes in plants

including the regulation of plant growth and development. Furthermore, melatonin acts not only as a

signaling molecule for enhancing the resistance of plants to biotic and abiotic stresses, but also as a

powerful free-radical scavenger and has a direct antioxidant activity (Arnao and Hernández-Ruiz, 2015).

Although effects of melatonin on drought tolerant and the role of melatonin in alleviating drought stress

has been widely described for several species, the role of melatonin in rice response to stress is still less

well known. Therefore, this research purposes to investigate the effects of melatonin on growth, some

physiological characteristics and antioxidant enzyme activities in rice under drought stress.

2. Results

The results showed that after 7 days of drought stress, rice seedling growth including shoot length, root

length, fresh weight and dry weight significantly decreased in non-treated plant (0 µM melatonin)

compared to the control. The foliar spray with melatonin benefitted to rice seedlings by increasing shoot

and root length as well as root fresh weight and root dry weight compared to non-treated plant. However,

shoot fresh weight and shoot dry weight were not barely altered from non-treated plant. Relative water

content significantly decreased in non-treated plant compared to the control, with reduction by 28%. The

application of melatonin showed relative water content of treated plant higher than that of non-treated

plant. The drought-stressed plant showed higher chlorophyll content compared to the control plant. The

foliar spray with melatonin slightly increased chlorophyll content compared to non-treated plant. Under

drought stress, the electrolyte leakage significantly increased in non-treated compared to the control,

however, melatonin treatment had a positive effect on electrolyte leakage. Melatonin decreased the

electrolyte leakage, that was lower than non-treated plant. Furthermore, malondialdehyde content, an

indicator of lipid peroxidation was not altered. In addition, drought stress increased the activities of

antioxidant enzymes such as SOD, CAT, APX and POD in rice seedling and the application of exogenous

melatonin tended to increase these enzymes activities compared to non-treated plant.

Gene Expression in the Resistant and Susceptible to Bombyx Mori Nucleopolyhedrovirus

(BmNPV) Silkworm Strains

Saowani Khattamart, Monthira Monthatong

Department of Biology, Faculty of Science, Khon Kaen University, Thailand

E-mail: saowani-j@hotmail.com

1. Background

The silkworm, Bombyx mori, is an economically important insect group for the sericulture or production

of silk fiber, processing to silk thread and silk fabric. In addition, the two main proteins from silk cocoon,

fibroin and sericin, have been applied in pharmaceuticals and cosmetics such as wound healing,

antiwrinkle and anti aging (Yao et al., 2003). However, the major problem in rearing silkworm is

pathogenic diseases causing the cocoon crop loss (Saksung and Tawonanukulkit, 1997). One of the major

diseases is “grasserie disease” induced by Bombyx mori nucleopolyhedrovirus (BmNPV) infection.

Subsequently, many studies have reported proteins involving in antiviral mechanism in silkworm that are

Bmlipase-1, serine protease-2, lipase-1 and alkaline trypsin proteins (Ponnuvael et al., 2003; Nakazawa et

al., 2004). In Thailand, the classification of mulberry silkworm are divided into three races by their

origins that are Thai native, hybrid and foreign silkworm strains. The Thai native silkworms seem more

resistant to viruses than the foreign silkworm. However, the levels of resistance to BmNPV infection of

silkworm strain have not been reported. Therefore, the prior aim of this study is to investigate the level of

potential resistance to BmNPV infection in both the resistant and susceptible larvae strains by comparing

target gene expressions using qRT-PCR.

2. Results

Grassery disease of silkworm (Bombyx mori) caused by Bombyx mori nuclear polyhedrosis virus

(BmNPV) is one of important epidemic diseases affecting the sericulture in Thailand. This study aimed to

investigate genes expressions related to BmNPV response in silkworm. Eight strains of silkworm

including Sumrong, Nanglai, Nangsiw, Nangtui, Nangnoi, Kaki, Pangpuay and NNK8 were used in this

experiment. Total of 20 larvae of each strains were divided into two groups; the treatment group and the

control group. The treatment group, the concentration of polyhedral virus with 105 OB/ml was spread on

fresh mulberry leaf and fed the fourth instar on the first meal. The control group was fed on fresh

mulberry leaf with sterilized distilled water coating instead of viral contamination. They were reared to

the fifth instar larval then individual mid-gut were dissected for RNA extraction by TRIzol. A total

amount of extracted RNAs were between 1179.44 to 1782.93 ng/µl and the RNA purities were between

1.99 to 2.05. The cDNA was synthesized by reverse transcription and then the cDNAs were investigated

by Real-time quantitative PCR (qRT-PCR). The transcription level of Bmlipase-1 was increasingly

expressed in the Sumrong and Nanglai strains with significantly different (p<0.05) when compared to the

control group.

1. Background/ Objectives and Goals

The 2008-09 credit crisis has highlighted the importance of counterparty risk in connection with valuation

and risk management of credit derivatives. Counterparty risk in general is the risk that the party to a

financial contract may fail to make all the payments required by the contract, causing losses to the other

party. Contracts privately negotiated between counterparties like over-the-counter (OTC) derivatives are

most likely subject to counterparty risk. Modeling counterparty credit exposure for credit derivatives is

more complicated than for other noncredit products, since the reference credit and counterparty may

display some sort of default correlation. A few studies have been made to analyze the valuation of

counterparty risk within a credit default swap (CDS). In contrast, little attention has been given to analyze

the counterparty risk embedded in a basket default swap (BDS). Therefore, we take into account of

counterparty risk for the valuation of a BDS in this paper, aiming to fill the gap in the literature on the

analysis of counterparty risk within credit derivatives.

2. Expected Results/ Conclusion/ Contribution

Based on the IS algorithm proposed in the paper, we will conduct numerical analyses of the estimation of

fair spreads for k-th-to-default BDSs, and examine how the counterparty credit risk is priced in BDS

contracts. It is expected to see that the estimator for the default leg based on our IS algorithm is more

efficient than that based on naive Monte Carlo simulations. We expect that the IS estimator based on our

proposed algorithm displays a marked decrease in variance, especially when the chance of the k-th default

event occurring is highly unlikely. Finally, it is expected that our numerical results can provide evidence

about how the counterparty credit risk is priced in the market via the calculation of the CVA values.

We contribute to the literature by providing a solid basis for the estimation of k-th-to-default BDS default

legs after taking into account the counterparty risk. We expect that our numerical analyses have

implications for the debate on the regulation of derivatives markets.

Generalized Riskiness-Minimizing Hedge Ratio: Considerations of Physical Risk and

Risk-Tolerance

Jen-Wei Yang

Department of Economics, Soochow University, Taiwan (ROC)

E-mail: jw@scu.edu.tw

Abstract

This study proposes the generalized-riskiness-minimizing spot-futures hedge ratio which is determined by

minimizing the generalized riskiness index of the hedge portfolio return, where the generalized riskiness

index is proposed by Bali, Cakici, and Chabi-Yo (2011). Unlike the most risk indices adopted in the

previous studies, this risk index (1) measures the physical risk of an asset return as well as the

risk-tolerance of an investor; (2) satisfies monotonicity with respect to stochastic dominance. The solution

for this optimal hedge ratio are provided and can be estimated by method-of-moment. By using this hedge

ratio, the empirical findings show that the hedgers can pay smaller hedge costs to eliminate the larger

total risk (including the larger risk-tolerance-induced risk and a little bit smaller physical risk) than the

optimal hedge ratios which are determined by minimizing the riskiness proposed by Foster and Hart

(2009).

1. Background/ Objectives and Goals

In the condition of information asymmetry, mortgage-backed securities (MBS) were generally considered

as an information insensitive design with high liquidity. But a large amount of mortgage-backed securities

were in the lack of liquidity for a relatively long time during and after the subprime crisis, even some of

the securities were not in credit deterioration, which became an puzzle in academy. From the perspective

of information asymmetry, the research introduced the concept of investor confidence in theoretical and

empirical analysis, and tried to explain why the mortgage-backed securities in good quality lacked

liquidity during and after subprime crisis.

2. Expected Results/ Conclusion/ Contribution

The research found that, when the signals from the design of mortgage-backed securities, such as MBS

credit ratings, can effectively increase investor confidence, investors tend to increase the expected value

of the securities, which would decrease the volatility and increase the trading volumes, which improves

the liquidity. If the signals expose severe problems, such as the MBS credit ratings were questioned

during and after subprime crisis, investor confidence would be hurt since the investors don’t have other

more information about the securities under information asymmetry, and investors tend to leave the

market, which means, the liquidity would dry up. The results give a reasonable explanation to the

breakdown of MBS market during and after the subprime crisis. The result empirically represents as that

the bid price of mortgage-backed securities has significant excess earnings with the changes of MBS

credit ratings; when the credit ratings get upgrading, the investors tend to give higher bid price than its

expected value, which proves the existence of investor confidence in the market.

This study extends the previous papers regarding the influence of business culture over decision making

of the firm (see, for example, Hilary and Hui, 2009; Li et al., 2013) to investigate how the local culture of

the headquarter of a firm affects the corporate risk-taking behavior in mergers and acquisitions (M&As).

As tender offer has been considered as a risky takeover strategy to bidders, the US tender offer deals

during 1977-2015 are collected to examine whether the firm located in a county with higher regional

gambling preference will be more possible to adopt the riskier tender offer strategy and how such regional

cultural factor influences the short-/long-term performance of these bidders.

Using US merger and acquisition data during 1977-2015, the empirical results show that the higher the

gambling preference of a region is, the more possible an acquirer headquartered in this region chooses

tender offer strategy in its merger, and the higher price it is willing to pay. Although the short-term

announcement effect of tender offers across regions are statistically indifferent, it is also found that the

acquirers headquartered in the regions with higher gambling preferences have significantly higher returns

in the long term, regardless of whether the cumulated abnormal return (CAR) or other market-based

measures are used. These results are robust and consistent with early studies in that the culture of a region

do change the risk attitudes of the firm headquartered there to corporate decisions and strategies,

including tender offer.

Abstract

Laboratory experiments were perfumed to determine the rates of processes responsible for the recovery of

dissolved oxygen (DO) in an embayment connected to a main channel. We measured the horizontal

velocity vectors to evaluate large-scale circulation within the embayment and measured the time series of

DO concentrations during the recovery processes promoted by supply from the main channel. The present

study highlights the influence of the aperture ratio of the embayment/main-channel opening. and finally,

it was found that DO recovery rate is controlled by the bulk-mean velocity in the main channel, the

aperture ratio, and the position of the embayment opening.

Abstract

Headspace solid-phase microextraction (HS-SPME) was developed for extraction of organic acid

preservatives, which are benzoic acid, sorbic acid and propionic acid, in fruit juice and analyzed by gas

chromatography with flame ionization detector (GC-FID). The 85 µm polyacrylate coated fiber (PA) was

used to extract the analytes from headspace of 10 mL sample solution and were desorbed by thermal

desorption at 250 oC in the GC injection port. The optimum condition for HS-SPME was 10 mL of

sample solution, extraction temperature of 50 oC, extraction time of 30 min and the addition of 0.05

mol/L sulfuric acid and 4.5 g of anhydrous sodium sulfate. Under the optimum condition, high accuracy

and precision of three organic acid preservatives in fruit juice were achieved.

Abstract

The recovery of waste engine oil was investigated in this study by thermal cracking reaction. The pyrolysis

process was designed as two-stage reactor including distillation process. The various factors affected to the

product yield and property were investigated, such as reactor configuration, nitrogen carrier gas flowrate

and reactor temperature. We found that the configuration as two-stage reactor increased the residence time

resulting in the improvement of final product properties: specific gravity and viscosity. The high yield of

pyrolysis oil was obtained from the single-stage configuration at high temperature but relatively low in

quality. Moreover, packed bed in the second reactor could enhance the color and properties of pyrolysis oil.

1. Background

Due to denaturation of protein drugs via oral administration, which is the most convenient mode of drug

delivery, protein drugs are usually administered by parenteral route. Another challenge in protein drug

delivery is to maintain the tertiary protein structure, which is essential to bioactivity. Exposure of protein

drugs to unfavorable conditions during formulation could reduce or even destroy their bioactivities. In

order to address all these concerns, one technique for oral delivery of protein drugs that can be used is by

employing protective coatings to control delivery. This may be carried out by the microencapsulation

process which isolates the core from its surrounding hostile environment. Most often than not, sodium

alginate-based hydrogels are well suited in microencapsulation applications because of its low cost and

stability when exposed to an acidic environment. As far as established methods are concerned,

encapsulation of proteins in alginate microparticles still suffers from certain limitations.

Therefore, this study’s major goal is to use external ionotropic gelation, a very convenient

microencapsulation method, in developing protein-loaded sodium alginate based microparticles and

evaluate its encapsulation efficiency and the model protein’s in vitro release behavior. Also, bovine serum

albumin (BSA) will be used as a model protein in this study.

2. Results

SEM images show that addition of model protein results to increase size and production of smoother

surface of micropaticles. Also, low moisture content was found for the fabricated microparticles of around

9.97%. with respect to swelling, acidic medium has caused minimal swelling while larger swelling ratios

were observed for pH 7.4 medium. Furthermore, encapsulation efficiency of BSA-loaded alginate

microparticles was recorded to be around 46.74%. Lastly, microparticle samples exhibited initial burst

effect after two hours of dissolution. Data also shows cumulative protein release of around 73.67% after

five hours of dissolution.

Abstract

In Taiwan, cultural & creative industry parks have become one of the developmental strategies of every

government's policy integrating cultural and economic development, and most of them adopt the method

of contracting-out management, that is, public-private-partnerships (PPPs). However, not every park can

create economic efficacy and achieve policy goals. This article focuses on the problems and controversies

of the outsourcing of Taiwan’s cultural creative industry parks with the theories of principal-and-agency

theory. Firstly, this article lists some problems of the cultural parks (five managed by the Cultural

Ministry and one by Taipei City Government) with the methods of literature review, depth interview and

case study & comparison. Secondly, this article further explains the types and reasons of these

controversies. Lastly, this article proposes some policy suggestions for these controversies, expecting to

make the governmental outsourcing more successful.

Keywords: Cultural creative industry park, public-private-partnerships (PPPs), principal-and-agency

Abstract

This research paper aimed to argue that community-based tourism was the best solution for sustainable

social system and environment, in this case, was Mae Kampong community. Tourism has been growing

continually in the global economy. Many countries relied on tourism for those benefits and development

and Thailand as well. However, the revenues from mainstream tourism impacted to the social system

were dramatically changed, natural resources were largely exploited, and the economic profits were not

distributed fairly. Thus, The community-based management (CBT) became an alternative sustainable

solution. The qualitative was deployed as documentary research, the data collection was gathered from

the official report and previous research. Then, the CBT model and participation theory were employed

for analyzing. The research result founded that The community-based Tourism (CBT) improved a social

system in Thailand is along with the environment. This research suggests that the Thai government should

apply the CBT model and participation especially for a local community to nationwide.

Abstract

This paper discusses the epistemological challenges faced by social scientists in conducting qualitative

research on overseas Chinese family and consumption. It discusses the concepts, issues and subjectivity

challenges on constructing and narrating the Chinese realities in consumption research. It proposes an

institutional-actor approach to understand the concept of familism among the Chinese when investigating

their consumption behaviors. It argues that for the development of overseas Chinese reality, their

identities are largely shaped by socio-historical and socio-economic events. Particularly, the overseas

Chinese diaspora in the Southeast Asian region which has succeeded in becoming not only a formidable

economic force today, but also a unique form of capitalism in contemporary times. With such affluence

among the Chinese, however, there have been very few studies done on their capitalistic consumption

albeit any alterations to their existing value systems, and social institutions and ties. Several studies have

concluded that certain family systems not only survive in modern economic context but that they often

function positively to enable individuals to mobilize capital and other resources for production and

consumption.

Abstract

Overall the coastal area is one area that has an important role and is a source of life for some people.

Crucial issues regarding impacts climate change such as sea level rise will cause the vulnerability in

coastal areas which has an impact on infrastructure damage and threatens the socio-economic conditions

of the community. One of the settlements that experienced the effects of climate change occurred in

Tambak Lorok, North Semarang District. Tambak Lorok is a coastal area in Semarang, which has very

poor settlement conditions. Settlements are increasingly vulnerable to climate change needs adaptive

capacity. The purpose of this study is to determine the capacity of adaptation vulnerabilities and disasters

as an impact from climate change that occurs in the coastal settlement. The method used is quantitative

with scoring analysis techniques and descriptive analysis. For adaptation capacity carried out by the

community shows that household level adaptation capacity shows a high level compared to the capacity

of adaptation carried out at the community or city level only at a moderate level. Assessments related to

adaptation capacity identified through indicators the ability of adapters, financials, technology,

performance, and management to take place in each area are household level, community level, and city

level.

Abstract

For the Mathieu equation, 2 2 0x a x b x cos( t ) we may divide the plane (a, b) into stable

and unstable zones called the stability chart. The stability chart is characterizing by the boundary curves

between the stable and unstable zones, indicate the values of (a, b) at which the equation shows periodic

response. The solutions of Mathieu equation in a stable zone are interesting as it is either periodic or

quasi-periodic. Linearity of the Mathieu equation makes the stability chart to be independent of the initial

conditions.

This paper show how we can examine the behavior of Mathieu equation in an stable zone to determine its

- -transition curves

will be examined as a sample stable zone. It will be shown that there are splitting curves within the stable

zone corresponding to periodic solutions. The boundary curves are associated to the point where the

Mathieu equation as stable behavior on one side and unstable on the other side. However, the new curves

are associated to the point at which the equation has periodic solutions and is stable on both ides.

Employing power spectral density, we discover the distribution of sub and super-harmonics as well as

quasi-periodic solutions of Mathieu equation. Energy-rate methods, time response, phase plane, Poincare

points, and power spectral density are utilized to examine the dynamic behavior of Mathieu equation at

different points within the stable zone.

1. Background

In tissue paper folding machines, the paper is transferred on the surface of folding drums by air suction,

Fig. 1. Small openings of air intake tubes are distributed on the folding drum surfaces. The air intake

tubes and air suction channels which run through the interior of the drum provide the pressure difference

between the opposite sides of the papers to form the suction force to attract the paper. At the downstream

of the folding drums, the paper sheets are released with air pressure discharge. Various multi-panel

interfolded overlap patterns can be achieved with different finger mechanisms, Fig.2. As the production

speed increases with wider paper webs, it was found out that the edges of sheet panels are misaligned as

they are stacked on the pack of folded sheets built at the downstream of folding drums. The disarranged

edges of the sheet packs cause unsatisfaction on the appearance quality and require engineering

investigation.

2. Results

Figure 4 shows the pressure transient responses of air intake tubes for the suction process for the first 3

seconds. Figure 5 shows the pressure transient responses of air intake tubes for the discharge process for

the subsequent 5 seconds. The required suction pressures to attract the tissue paper sheets attached to the

drum surfaces are calculated and plotted on the figures of the pressure transient responses to estimate the

response time for the folding drums to attract and discharge the paper sheets. It is found that the required

suction pressure of air intake tubes built up very fast for the attraction process. The delay for the attraction

of the paper sheets to the drum surface seems impossible, i.e., no slippage of the paper sheets on the

folding drums. However, the discharge process shows longer response times are required to release the

paper sheets, especially for the air intake tubes in the middle region of the folding drum. The difference

of the release time between the inner most and outermost air intake tubes can be up to 2 ms, for a folding

drum design of 3400mm span. The corresponding arc length of the folding drum to the 2ms response time

is about 5 mm, which agrees closely with the amount of edge misalignment on the pack of folded sheets.

Due to the fluid inertia, the pressures of the air intake tubes change slower near the middle region of the

folding drum than those in the outer regions, which are close to the vacuum pump. The air suction process

is a forced process caused by the vacuum pump. But the air discharge process is a passive process by

venting to the atmosphere. Also, the longer span of the folding drum design the larger the response time

difference between the air intake tubes in the middle region and outer region of the folding drum.

Abstract

Photovoltaic systems are becoming increasingly important and widely used in many applications, as they

are considered cleaner and renewable. Recently, there has been a technology research on the Internet of

Things (IoT) Smart Environment Monitoring and Real Time Systems (SEMAR) that can control and

analyze air quality parameters, perforated roads and congestion in a location in real time so that it can

help government in the massacre of road conditions. But now the development of this technology requires

an energy generation system that can be integrated easily and without burdening vehicles used to monitor

road conditions. To meet the needs of electrical energy is made independent power plant in the form of

photovoltaic system. The power plant is built using Maximum Power Point Tracking (MPPT) Modified

Perturbation and Observation (P&O) Technique to obtain a more efficient and effective system. In the

design, the size of solar photovoltaic is 18 V 50 Wp with a battery of 12 V 17 Ah, so to perform the

battery charging process required MPPT solar charger capacity of 5 A. With the use of MPPT MP&O,

obtained an increase of electric power from without MPPT, average of 9.67%.

Abstract

Major portion of the Lower Officers’ Hill colony situated in the city of Kohima, India, have been affected

including a 200 m section of Asian Highway-1 (AH-1), severely disrupting traffic and causing great

inconvenience for decades to the people of the Indian states of Nagaland and Manipur. The area is

composed of the Disang Group, made up primarily of shales intercalated with thin beds of sandstone and

siltstone that are highly jointed, fractured and weathered. A major stream called the Sitsie Rü flows in the

western boundary while two tributaries run parallel on the north and south. The area falls in a residential

zone that receives heavy rainfall during the Monsoon increasing the amount of water percolation into the

soil and toe erosion by the streams that pose great threat to the settlers. Geotechnical analyses of the slope

material and kinematic analysis of joint data is used to determine the existing slope strength and to assess

the potential failure mode. Study of satellite imageries are also undertaken to determine the local

structural influence of this unstable zone. The study aims to suggest some unique remedial measures for

this complex landside and thereby address this chronic problem that has tormented the people for several

years.

1. Introduction

There have been a number of major international fire accidents involving long vehicle tunnels. A fire

accident in the Mont Blanc tunnel connecting France with Italy happened on March 24, 1999. The tunnel

is 11.6 km long. The accident caused a large truck to catch fire and 39 people died. On October 24, 2001,

a large freight train caught fire in a 16.9 km long St. Gotthard tunnel between Italy and Switzerland. In

the accident, 11 people were killed and many people were injured.

There are many international studies to analyze the fire hazards of vehicle tunnels, but most of the

research objects are straight tunnels. The slope of the tunnel, the type of vehicle, and the flow of traffic

have a great influence on the development of tunnel fires. When formulating an emergency response

strategy for a tunnel, all parameters must be considered.

3. Results and discussion

After reviewing the weather data, the natural wind direction in summer and winter are in the opposite

direction. This paper analyzed the impact in the scene of the fire incident influenced by natural wind. The

famous international fire simulation software (FDS) was used to simulate the situation of three different

tunnel fire scenarios under the influence of seasonal winds.

In this study, the visibility of people and the temperature are used to discuss the environment which the

people in the tunnel are evacuated when a tunnel fire occurs. Three different cases were simulated to

analyze the influence of natural wind on Kaohsiung Cross-Harbor Tunnel. Cases were no natural wind,

winter wind (from January to March) and summer monsoon (from July to September). The results show

that the spread of smoke is greatly affected by the natural wind. The conclusions are not found in the past

research. The formulation of disaster response strategies must take into account the impact of natural

winds.

1. Research purposes

On the scene of a fire, smoke also does great harm to human in addition to the high temperature. The

anti-smoke tool has the characteristic of obstructing the view, which will affect people’s evacuation

activity. Some standards about full-scale hot smoke test have been published to analyze the smoke

controlling ability. The common test standards include 4391-1999 Smoke management systems - Hot

smoke test in Australia, JIS A4303 – 1994 Inspection Standard of Smoke Exhaust Equipment in Full-scale

Tests in Japan, GA/T 999-2012 Test method for verifying field performance of smoke management

system – Hot smoke test in China, and CNS 15937: Test method for field performance of smoke control

system − Hot smoke test in Taiwan. Although some test standards are issued internationally, the quantity

of the visual tracer particle injected has not been described in detail. Different fire loads have their

corresponding smoke generation amount. Some researches discuss the smoke generation amount. Some

empirical plume equations were developed at the California Institute of Technology (Cetegan, Zukoski,

and Kubota 1982), National Institute of Standards and Technology (McCaffrey 1983), and Factory

Mutual Research Corporation (Heskestad 1983, 1984). According to Handbook of smoke control

engineering, the smoke generation amount is shown in Equation (1a) and (1b) [20]: If there are too much

or insufficient smoke generated on the test site, it is possible to cause the distorted judgment result.

Therefore, it is a necessary topic to quantify the smoke generation rate of smoke generator during the hot

smoke test.

3. Results and discussion

There are some international standards for building smoke extraction system using full-scale hot smoke

test. For the judgment of validity, the flow direction of the smoke can only be visually observed. In this

study, smoke was released in a room to investigate the procedure for measuring the smoke generation rate.

This research applies some devices to do the test to define the procedure how to measure smoke exhaust

amount in a quantization way. In order to keep the smoke continuously floating during the experiment,

400c.c. of ethanol was burned in this study. The indoor temperature is moderately raised and the

buoyancy of the smoke can be maintained. Recording the thermocouple measurement temperature can

analyze the state of the room. The spread of hot smoke in the room can be observed through the four sets

of CCTV. From the results, it is proved that the concentration and distribution of smoke are immediately

and accurately identified by the decay rate of light and the recorded CCTV images.

Abstract

The occurrence of cavitation phenomenon is common in a fluid flow as the hydrostatic pressure of the

fluid reaches the vapour pressure at a given temperature. In recent years, cavitation phenomenon is widely

used as a constructive tool in engineering. Orifice plate design is crucial to generate hydrodynamic

cavitation and achieve the desired cavitating intensity for engineering applications. Hence, the main

objective of this paper is to establish a relation between cavitation intensity and orifice constriction ratio.

Therefore, two sets of orifice plates namely Single Hole Orifice (SHO) and Multiple Hole Orifice (MHO)

are designed and investigated. Cavitation intensity of all the orifice plates is quantified using cavitation

number. Finally, an empirical model is developed to establish the relationship between cavitation number

(σ) and orifice constriction ratio (𝛽).

Abstract

Technologies have the potential to change the way family businesses access and share information about

the owner’s way of life orientation. With the evolution of the Internet, WWW and social media, family

business owners face the dilemma of how to run their businesses their way while adopting technologies

that can help them run their businesses. This paper examines technology adoption and way of life by

gender of a rare panel dataset of U.S. family business owners who remained in business over 19 years.

Technology adoption was compared by Internet and social media use, and way of life of the owners was

examined by whether social media was used. Recommendations for future study are presented, as are

suggestions for how the study findings can guide and inform public policy and practices by business and

community development practitioners.

Abstract

Institution is defined as a society or an established organization for an educational, social, religious or

similar purpose that is working together for a common goal. Church is an example of religious

organization representing an institution. This study aims to assess the religious tourism and carrying

capacity of the National Shrine of Saint Padre Pio in Batangas. Data were gathered using survey and key

informant interview to determine the socio-demographic profile of the respondents and church structure,

rules regarding National Shrine of Saint Padre Pio. The study revealed that tourist-respondents in the area

are majority young adults in the age group of twenty to twenty five years old that have a monthly income

of ten thousand pesos and below. This is because in this stage of life, youth enjoy doing adventure and

activities like going to different places that have significant features in the country. Church, Healing,

Family bonding and Recreation are the common reasons of the visitors in visiting the area. Mode of

transportation is mostly by the use of private vehicles specifically cars and motorcycles. Carrying

capacity and total daily visit of the shrine is computed using the formula of Boullon and Limit of

Acceptable Change. The carrying capacity for Shrine was computed to be 1,720 and 431 for the upper

and lower limit respectively in the assumption that 8,000 square meters is being utilize while the carrying

capacity for 16,000 square meters is 3,442 and 861 for the lower and upper limit respectively. The total

daily visit the lower limit is 5,735 and 11,470 persons for 50% and 100% usage of the area respectively.

For the upper limit the standard total daily visit is 1,435 and 2,870 persons for 50% and 100% usage of

the area respectively. With the growing volume of visitors, environmental concerns like orderliness and

cleanliness may also be included in the set of rules when in the premises of the National Shrine of Saint

Padre Pio more specific for the solid waste management.

Buddhist University, Thailand.

E-mail: sudaporn_khiewngamdee@hotmail.com

Abstract

This research aims to study the concepts and types of priests of other religions which appear in the

Tipiṭaka, to study the Buddha's relationship with other religious priests and to use it as a practice for

Buddhists to live in harmony with other religions. The researcher used as a research method a

documentary and commentary of the Pali Tipiṭaka Siamese official version, Mahamakut Rajavidyalaya

and the Tipiṭaka and the Commentaries which are translations of the Mahamakut Rajavidyalaya

Foundation under Royal Patronage. The study mainly focused on the appearance of the Vinaya Tipiṭaka

and the Suttanta Piṭaka.

The result of this study found that other religions and priests, which appear in the Tipitaka as the 6

teachers' religions; Including Purnakassapa, Makhaligosala, Ajitakesakambala, Pakudhakaccayana,

Niganthanāṭaputra and Sañjayvelaṭṭhaputra. Each religion has a different viewpoint. Other religious

priests include Paribajaka, Tāpasa, Jatila, Añyatithika and Hermits. The relationship in terms of being an

adversary include Brahmins, Huhukajāti, Dīghanakhaparibājaka and Saccaka-Nigantha and so on. Then,

there is also a friendly relationship, such as Sīhasenapati, a disciple of Nigantha, Kūṭaḍanta-brahmana,

Mahasakuludayiparibajaka, Paribbajaka named Kandaraka and Dῑghatapassῑ- Nigantha.

When analyzing why other religious priests changed Buddhism. Due to the use of the miraculous miracle,

and from the curiosity or intolerance in the study of that person. In the past, the contact of the Buddha

with other religion's priests was friendly. If there was something to criticize, when he clarified, it was

considered terminated. If there is some good, it was accepted and applied in Buddhism. If the act of the

Buddha was to deal with other religion's priests as a practice for the disciples of today, it is possible to do

so.

Abstract

Cosplayers are individuals who imitate the looks of different characters through the extravagant costumes

and dashing performances which they spend so much time in perfecting. Ryan and Deci’s

self-determination theory which is about the basic psychological needs namely autonomy, competence,

and relatedness that if satisfied leads to a positive well-being. The psychological needs are reflected in the

1. Background

In this study, we point out that Managing system and method of fishing gear using automatic

identification device. An automatic identification device installed in a fishing gear such as a fishing net,

fish trap fish trap provides the fishing gear information including the identification information and the

position information by wireless communication, it is received, classified, managed and stored by the

receive station. Using this information we can judge the status of fishing gear and systematically manage

it.

2. Methods

The automatic identification device installed in the fishing gear transmits the information of the fishing

gear(identification information, location information) regularly. This information is transmitted to the

control server of the land authority and registered in the database server.

The fishing gear management system can check the status and location of the fishing gear in real time and

analyzes the stored DB to determine and manage the state of the fishing gear. If an abnormal condition

occurs in the fishing gear, It transmits real-time abnormal condition to the control ship and it can perform

management (finding and tracking a lost fishing gear) of fishing gear.

3. Results

Recently, the maritime environment contaminated by the abandoned fishing gears. To solve this problem,

there are required systematic management techniques for the fishing gears based on ICT technologies.

The existed management system of fishing gears are optionally use by owners, but there needed a

monitoring and control architecture of integrated and national surveillance. To do this, we introduce the

architecture for effectiveness monitoring and management which collects position and state information

by automatic identification buoy device to send the fishing ship, administrator ship, and shore side control

center based on IoT and mobile network. Especially, we develop the ENC-based integrated control system

for efficiency management which provides position indication, state information display and loss alarm of

fishing gears.

1. Background

Visually impaired people face more difficulties in daily life than sighted people. For example, they may

encounter difficulties in finding an object at home or picking up an object that falls down on the ground.

When they go out, they may meet with accidents because of the barriers on the roads to their destinations.

2. Results

The assistive technology system can provide short-term but real-time remote visual assistance. It can

effectively help the visually impaired people to eliminate the problems encountered at that time. The

assistive technology system has an accessible user interface. The visually impaired people can operate the

system on their own without the help from anyone else. The assistive technology system is an embedded

system which equips with information sensors and can be self-propelled. It can move ahead, back and

make a turn. It has the function of barrier detection which can automatically stop the system from moving

ahead when there is a barrier ahead. The system features the function of image capture and can transmit

images of the surrounding environment to remote vision-assistive provider when needed. The image

capture device in the assistive technology system supports left and right steering. In addition, the assistive

technology system supports two-way audio transmission, and thus the visually impaired people and

vision-assistive providers can communicate directly with each other. The vision-assistive providers can

remotely control the system and provide guidance according to the environment and conditions faced by

the visually impaired. The remote control can be operated by using a computer or a mobile phone.

Visually impaired people can use the developed assistive technology system at home or during movement.

In the future, the function of the sensing environmental information such as object color, environmental

brightness, luminance and temperature, and position of heat source and barriers will be extended. It is

hoped that the assistive technology system can be used by the visually impaired people for the purpose of

home safety.

1. Background

In this paper, we propose a method to efficiently acquire 3D image data using multiple Intel realsense

d435 cameras and ChArUco boards. The Intel RealSense Depth Camera D435 (Keselman, et al., 2017) is

an USB-powered camera that includes wider field of view depth sensors and a RGB sensor. ChArUco

board is a mixture of Chessboard and Aruco pattern. The advantage of this board is that each corner is

given an id so that it can be calibrated more accurately. In this paper, we calculate the affine matrix

between each camera and ChArUco board, and calculate the affine matrix which is transformed from each

camera to the reference camera coordinate system based on the acquired affine matrix. For more accurate

calibration, we define the cost function and optimize the parameters through function optimization with

the gradient descent method.

2. Results

Table 1 shows the results of this paper. In this paper, we reduced the average error from about 45mm to

5mm through 10 million iterations. The method proposed in this paper can efficiently remove errors that

occur in multiple RGBD camera calibration.

Abstract

In this paper, a mult-mode modulation transceiver for 3G and 4G wireless communication system is

proposed. Due to the fact that different wireless communication systems were developed in the recent

years, how to integrate different transceivers in one hardware is an important issue. This paper proposes a

multi-mode modulation scheme based on soft defined radio to integrate different modulation schemes

including quadrature phase shift keying (QPSK), 16 quadrature amplitude modulation(16 QAM) by

tuning the parameters. First, we verify signal simulation by Matlab, then we use VHDL of Alter Quartus

II softwave for timing simulation, pin planner and circuit design. Finally, download the software into the

Altera EP2C35F672C6N IC, and verify simulation with result by Logic Analyzer.

Abstract

The main purpose of this paper is to integrate the position sensorless control and Takagi-Sugeno (T-S)

speed control of permanent-magnet synchronous motor (PMSM). In the aspect of position sensorless

control, the extended electromotive force (EMF) algorithm is adopted and the extended EMF is estimated

by using a least-order observer. In the aspect of driving control, the T-S fuzzy models are implemented to

design the controller based on the concept of parallel distribution compensation (PDC). The stability

analysis is verified through Lyapunov theorem. Finally, the controller gains are obtained by Linear Matrix

Inequality (LMI). In this paper, dynamic model and system configuration are first introduced. Next, the

principle of extended EMF method is demonstrated. Moreover, the controller is designed based on T-S

fuzzy models and system stability is analyzed. All control schemes are digitally realized by the

microcontroller. Finally, the rotor position estimation and speed tracking performance are validated by

experimental results.

1. Background

The demand for image-based intelligent security system is steadily increasing, and the development of

deep learning is accelerating [1]. In order to improve the monitoring performance, an algorithm that

requires a large amount of calculation based on high resolution image information is required, but this

increases the cost of the security system. Therefore, it is possible to construct an economical system by

summarizing and transmitting high-resolution image information as much as possible [2, 3]. In this study,

a pedestrian detector and a tracer are used to express the behavior patterns of pedestrians in a shortened

way, and a method of effectively classifying normal and abnormal is presented.

2. Results

In order to judge the situation, it is assumed that 1 ~ 10 people are supposed to invade the group, and it is

assumed that there is unconventional movement, speed, directional movement, The abnormal situation

DB is constructed assuming that the delayed scene is abnormal. Lobby pedestrians are represented by

compressing the images in 48x14x3 pixels of density, speed and direction and classified them into normal

and abnormal by using CNN-LSTM deep learning network. We studied each 48x14x3 image using CNN

network and learned the temporal classification by connecting the fully connected layer sequence of CNN

network to the input of LSTM network.

We divided the entire DB into 50% training DB and 50% test DB, and performed learning by changing

the number of fully connected layer output nodes (N) and the number of hidden nodes (M) in LSTM.

Table 1 shows the results of the recall according to the parameter change. The relatively simple

CNN-LSTM structure shows that this performance is due to the efficient compression of the pedestrian

surveillance image to 48x14x3 level.

Department of Electronic Engineering, National Kaohsiung University of Science and Technology, First

Campus, Taiwan, ROC

E-mail: hhchen@nkfust.edu.tw

1. Background

Due to the benefits of low loss, high power-handling capability, and high selectivity, waveguide bandpass

filters (BPFs) have been widely used in wireless communication, radar, and satellite systems. Various

types of waveguide BPFs have been developed and extensively studied recently. However, most

investigations of the waveguide BPF designs adopted the “waveguide ports”, that is, uniformly extended

waveguides, to be the input and output ports of the filter (see an example shown in Fig. 1(a)). In many

practical applications, however, filters are connected to external systems and/or circuits using coaxial

cables. In such a scenario, a coaxial-to-waveguide adaptor would be required in the connection between

the filter with waveguide ports and external circuits. The additional coaxial-to-waveguide adaptors would

not only increase the cost of circuit integration, it could also influence the filter performances. Therefore,

the design of a waveguide BPF with coaxial feedings has become an important research in the modern

microwave engineering.

2. Results

To demonstrate the proposed design, a 6-pole BPF having Chebyshev response is developed in this work.

The center frequency f0, bandwidth BW, and passband return loss level of the filter are 5.8 GHz, 0.1 GHz

and 20 dB, respectively. Meanwhile, the standard WR-159 rectangular waveguide is utilized to construct

the filter. Fig. 2 shows the simulated and measured frequency responses of the filter. As can be seen, the

performances of the designed filter, including the bandwidth, in-band insertion loss (|S21|), and required

return loss (|S11|) level, are very close to the desired design. The in-band insertion loss is measured to be

around 0.58 dB, which is about 0.27 dB higher than the simulated result. The frequency shift between the

measured and simulated passbands is about 7.5 MHz. Also, only the return loss near the upper edge of the

passband is slightly higher than the expectation. The small discrepancies should be attributed to the

material losses and the variation in manufacture. These satisfied filter performances demonstrate the

validity of the proposed design method.

1. Background

In the field of surveillance cameras, People Counting is a technology that has long been developed for the

purpose of floating population analysis. However, due to the limitation of hardware specification of

embedded board, high performance algorithm could not be installed in camera. Launched in 2017, the

NVIDIA Jetson TX2 is a high-performance embedded board with a GPU. The proposed method proposes

a real time people counting using Jetson TX2 and a stereo camera.

2. Results

To evaluate the performance of the proposed method, 23 videos were taken every 5 minutes and the

counting accuracy was measured. Table 1 shows the comparative evaluation of the proposed method and

related work. The performance of the proposed method was measured 3.82% higher than the Axis-stereo

1. Background

Recently, there are many researches which adopts 4th industrial revolution element technologies (AI,

big-data, IoT, etc.) into maritime domain such as ship, shipyard and service (3S) fields. Especially,

intelligent analysis techniques apply to support maintenance for machinery equipment of ship as a service.

To do this, we need enough data to extract a meaningful analysis result from machinery facilities.

However, there are no standard for data exchange and management of machinery and automation

equipment in vessel.

To solve this problem, the standardization works of ISO 19847 and 19848 are in progress by TC 8. In the

these standards, the first one defines requirements of shipboard data servers to share filed data at sea, and

the other one covers requirements of standard data for shipboard machinery and equipment. The ISO

19847 presented shipboard data server as shown in Fig. 1 (a), and we configured a system architecture

based on the shipboard data server standard which as shown in Fig. 1 (b). In this paper, we implement the

shipboard data server based on the ISO 19847, and develop a fault prediction system using the

machine-learning (ML) method to provide maintenance supporting service for engine room (main engines,

generators, etc.) as one of the application. When the application exchanges data with server, it should

follow the IEC 61162-450 (streaming data), XML/JSON (formatted data) and/or CSV (file data) by the

ISO 19848.

2. Results

Currently, we finished ML for the developed system using the migrated AMS data. However, the data

only contains normal state values. Therefore, we going to research and develop a generation module for

simulation fault cases to adopt mutation of the genetic algorithm (GA). We will conduct the reinforcement

learning for the system, and connect with real-time data hereafter.

Abstract

Magnetic components, such as inductors, common mode inductors and transformers, are important

components of power converters. Their placement and wiring may affect the ability to suppress

electromagnetic interference noise. Due to the miniaturization and increasingly higher power density, the

composition of the power converters become more and more compact, which leads to the near field

coupling effects among the components. Our study analyzed the mechanism of the near-field magnetic

coupling among the magnetic components, and further verified the accuracy of the near-field magnetic

coupling parameters obtained by the simulation through experiments.

1. Background

Recently, many studies are actively in progress to apply the big-data analysis techniques of various fields.

In the sea navigation domain, the maritime big-data is defined as gathered data from the navigation and

communication equipment of ships such as AIS (automatic identification system). In addition, importance

of the maritime safety is emphasizing, because maritime accidents are rising with increasing of maritime

traffic. To reduce the accident risk, we proposed a safety information providing system to prevent the

collision accident by towing lines in this paper. The purpose of towing lines is to drag something on water

such as fishing nets and accident (shipwrecked, etc.) vessels by towing ships. However, the towing lines

are very difficult to distinguish in sea area when bad visibility condition or nighttime, especially for high

speed and small size ships. The system analyzes the degrees of risk to use a proposed algorithm based on

vessel traffic monitoring system, and provides the safety information service to the potential (high-risk)

ship by automatic VHF voice communication using the TTS (text-to-speech) module. The concept of the

system architecture is as shown in Fig. 1.

2. Results

We developed the vessel monitoring system based on ENC (electronic navigational chart) for VTS (vessel

traffic service) center, and implemented TTS module and digital to VHF voice converter. Also, we made

the DCPA and TCPA calculation modules, and we are optimizing the automatic tracking algorithm to find

the towing ships with fishing nets or accident vessels, and so on. In near future, we will accomplish the

integration the developed modules into the vessel monitoring system, and conduct enough testing.

Abstract

25 soybean koji samples were collected from the traditional markets in Taiwan. 62 strains of filamentous

fungi were isolated and identified, and these strains belong to 5 genera and 9 taxa. Aspergillus oryzae var.

oryzae and A. oryzae var. effusus are the dominant fungi in soybean koji samples. Otherwise, Rhizopus

arrhizus var. delemar occurred only in 64% of samples. A. oryzae (17 strains), Rhizopus microspores (11

strains) and R. delemar (2 strains) were selected from isolated koji strains, and the BCRC strain database

for studying. PDA plate with 1% corn starch was used for saccharification ability analysis to screen the

candidates. 17 strains of fungi were chosen that have better saccharification capacity in screening test. 8

strains of them were selected, and further were used to ferment with different types of grains. The

enzymes activity for the saccharifying ability, and the content of organic acids of fermented samples at

25ºC and 3 days of fermentation were evaluated. The result showed that organic acids content of the

fermented samples from the various strains fermented with different grains was significantly different.

Therefore, we develop a koji-starters selection with special grains for Shio-koji products application.

Abstract

The research progress in the centrifugal microfluidic platform provide great opportunities for simple but

effective analytical measurements in a variety of areas including biomedical engineering. In this study, we

propose an optical reader that can measure the transmittance in a very sensitive and rapid manner on a

hybrid paper-polymer centrifugal disc platform. This device enables real-time monitoring of multiple

samples by measuring the absorbance of the light transmitted through the paper integrated on the disc

between the light emitting diode (LED) and the photodiode (PD) regardless of the ambient light condition.

To confirm its efficiency, we analysed one of the blood's important indicators, glucose in a successful

manner within 10 seconds without any additional complex image analysis. In addition, we discussed the

results by comparing with the reflectance-based methods and with those of the previously reported studies

by introducing a figure of merit to evaluate the performance of the assay.

Abstract

Calcium carbonate (CaCO3) reinforced poly(butylene succinate) (PBS) composites have been produced

with different CaCO3 concentrations by using a twin screw extruder and an injection molding machines.

The mechanical, thermal and morphological properties as well as raw materials cost estimation have been

investigated. Experimental results indicated that the tensile and flexural strengths of the PBS matrix resin

were improved with increasing the CaCO3 contents from 10-30wt%. However, they were dropped at

50wt% due to the agglomerations of CaCO3. The heat distortion temperature (HDT) was higher than

those of the neat PBS resin by around 10°C. Scanning electron microscopy (SEM) indicated some

agglomerations at high CaCO3 contents. CaCO3 acted as nucleating agent only at 10wt%. Higher than this

content, it acted as filler and its agglomerations reduce the degree of crystallinity by around 5%.

Maximum reduction of raw materials cost by around 48% was observed at 50wt% CaCO3.

Abstract

To enhance the extraction efficiency of carotenoids from yellow pulp of Gac fruit, the use of Accellerase

1500, a commercial cellulase, with various concentrations (0.25-3%, w/w) was applied. The results

showed that the application of Accellerase could promote the extraction of carotenoids from yellow pulp

as evidenced by the lutein, lycopene and β-carotene tended to increase with increasing the levels of

Accellerase used. The suitable concentration of Accellerase was approximately 0.5% as indicated by the

highest contents of lutein and β-carotene were found while the lycopene content was still quite high.

According to the results, the utilization of cellulase treatment could be applied for increasing yield of

carotenoid extraction from carotenoid-rich plant, especially yellow pulp from Gac fruit.

1. Background

Paragonimus are commonly known as lung flukes that belongs to family Paragonomidae of order

Plagiorchiida (Toledo and Fried, 2014). Those trematodes are the main parasites for paragonimiasis in

lung of many mammal species and human (Sugiyama et., 2004). Those flukes reveal a large range of

prevalence in tropical and subtropical regions, especially in Africa, Asia, and South America (Peters and

Pasvol, 2007). In freshwater aquatics, crabs, snails and some shrimp have been known an important

zoonosis as intermediate host. Moreover, metacercarial lung flukes were found in crayfish that infected to

lung tissues of the crayfish-eating raccoon (Diaz, 2011). In Thailand, there are common 3 species of

Paragonimus such as P. westermani, P. siamensis, P. heterotremus that are the important case of

pulmonary, abdominal and cerebral paragonimiasis (Vajrasthira, 1986). Recently, in Thailand, crayfish

become the famous exotic pet and aquaculture for those decapod farms. However, crayfish (Cherax sp.)

were found in natural environments (Wanjit and Chaichana, 2013). Soh et al. (1966) also reported that

shrimp as intermediate host of paragonimus westermani in korea. Therefore, the aims of this study were

development of molecular genetic detection of lung fluke infection in crayfish (Procambarus and Cherax)

by using multiplex real time PCR analysis.

2. Results

All primers showed the specific bands of DNA-binding dye and the lengths in each PCR of individual

products. However, some band intensity for ITS2 primers were weak. Then, in real time PCR analysis,

paired primers of CO1 were used for detecting the Paragonimus in our experiments. Moreover, there was

undetectable for distilled water and genomics of nematode as negative controls. For a multiplex real time

PCR, three primer sets showed clearly signal detections for separating the genomic DNA of positive

controls in each sample of 3 metacercarial flukes. For detection limit, a minimal amount of DNA was 0.1

ng/ml. In 41 freshwater crabs collected from natural environments, the sensitivity, specificity and

accuracy of real time PCR analysis were 81.5, 90.0 and 85.0 %, respectively in comparison with light

microscopy independently. In experiments of crayfish, no signals of 16 samples were found in chemical

treatments with bithionol from 20 samples. Three samples from hepatopancreas were detected as P.

heterotremus, and 1 sample as P. westermani. No signal detection was found in P. siamensis. However,

parasites were not observed under light microscope analysis for any sample. In experimental groups with

fed on crab tissues, 11samples from hepatopancreas were detected as P. heterotremus for 7 samples, and

as P. westermani for 4 samples form 20 samples. Nine samples were not detectable. In light microscopic

observations, the results were congruent with molecular detections for P. heterotremus for 6 samples and

P. westermani for 2 samples. In contrast, 2 samples were examined as P. heterotremus under a light

microscope, but not in real time PCR. Eight samples in light microscopic results were agreed with in PCR

that there were not found any positive result for both methods. However, 2 samples were detectable in

PCR but not in light microscope.

1. Background

Nano dimensions provide substances with a number of specific properties applicable in different areas of

human activity. Silver and gold nanoparticles have considerable potential for medical applications. At

present, nanoparticles are predominantly produced by physicochemical procedures that are often not

environmentally friendly and green nanotechnology is therefore a desirable alternative (Pereira L. et al.,

2015; Huang J. L. et al., 2015. Extensive and long-term knowledge in the field of microbial cultivations,

ease process scale up and the enormous range of enzyme activities of microorganisms predict their use in

this field. In the paper, we summarize our knowledge of nanoparticle production using different types of

bacteria and the basic characteristics of the obtained nanoparticles.

2. Results

The screening of the 12 strains of bacteria proved that extracellular enzymes of all strains were able to

synthesize silver and gold particles from AgNO3 or HAuCl4 in varying amounts. The largest amount of

nanoparticles was observed after 72 hours of incubation in the supernatant at a 10 mM concentration of

AgNO3 or HAuCl4. The detected absorption maxima for semiquantitative spectrophotometric

determination of the presence nanoparticles has to be determined individually depending on the size of

nanoparticles produced by different strains. Pseudomonas fluorescens CCM 2115 and Pseudomonas

aeruginosa DBM 3777 showed the highest ability to synthesize silver and gold nanoparticles.

Synthesized nanoparticles showed a very narrow distribution of sizes and shapes, which is important for

practical use. Most often, they were almost spherical polygons. P. aeruginosa generate relatively large

polygons silver nanoparticles with dimensions of 50-90 nm. In contrast, B. subtilis synthesized silver

polygons of about 10 nm in size, and P. fluorescence formed fibrous shapes with a diameter of about 10

nm. P. aeruginosa and E. coli synthesized polygonal nanoparticles of gold up to 15 nm in size with a

deviation of approximately ±3 nm.

Department of Biotechnology, University of Chemistry and Technology Prague, Czech Republic,

* E-mail: jan.masak@vscht.cz

1. Background

Rhamnolipids are biosurfactants with many potential industrial applications due to their unique properties

- biodegradability, physico-chemical stability and low toxicity. Although rhamnolipids were studied for

more than 60 years, industrial production allowing their commercial use is still not satisfactorily solved.

The big problem is still the high price and purity of the products obtained. A possible solution is to

increase the productivity of production strains and improve downstream processes which make up a

significant part of the total production cost (Abdel-Magoud et al., 2011; Randhawa and Rahman., 2014;

Chong, 2017). The aim of our research was to optimize the batch cultivation in a laboratory bioreactor

with the purpose to enhance the rhamnolipid production.

2. Results

Glycerol, used as the sole carbon source, provided very good yields of rhamnolipids for the given strain

and as a hydrophilic substrate, allowed easy isolation of rhamnolipids from the cultivation media.

Although limitation of nutrients in the medium is usually a significant factor in the production of

rhamnolipid-type metabolites, we have not find an increase in production even when the phosphorus

content is reduced to 10% of the concentration used in the standard medium. On the other hand, a 20%

reduction in total nutrient concentration in the medium resulted in a 26% increase in rhamnolipid

production in the bioreactor. However, this finding can also have a considerable economic effect,

especially in larger cultivation volumes. Another effective mechanism for increasing the production of

rhamnolipids was modification of the cultivation temperature. During cultivation of P. aeruginosa DBM

3774 at 37 °C, the production of rhamnolipids doubled compared to cultivation at 30 °C. P. aeruginosa

DBM 3774 shown considerable variability in the production of rhamnolipids depending on pH. This

strain achieves the highest production of rhamnolipids at pH in the range of 6.7 to 7.1, which is a little

higher in comparison to other producers. After optimization of all tested parameters achieved

concentration of rhamnose in the medium was 5.7 g / l, which corresponds to a concentration

rhamnolipids 14.0 g / l.

Glucose oxidase (GOx) composites with conducting polymers (e.g., polypyrrole (Ppy)) are excellent

nanobiomaterials suitable for the design of bioelectronics devices such as biosensors and biofuel cells.

Immobilization of GOx is a very important issue affecting the enzymatic activity, biodegradability,

longevity and stability, which is one the most important and challenging characteristics in practical

application of biosensors. The purpose of this research was to evaluate impact of polypyrrole (Ppy)

composites on stability of GOx enzyme.

Spectroscopic properties of GOx, flavin adenine dinucleotide (FAD) and composites of these compounds

with polypyrrole (Ppy) were investigated in a sodium acetate buffer solution. In the present study, the

nanosecond fluorescence quenching was observed for GOx/Ppy and FAD/Ppy composites by the

steady-state absorption and time-resolved fluorescence spectroscopy technique.

The exploration of native GOx and FAD solutions confirmed that about 5% of FAD dissociated from

GOx during the period of solution preparation, and this fraction remained constant for 1 month. It has

been found that the Ppy, which formed composites with FAD and GOx, facilitated the removal of FAD

molecules from GOx and twice reduced the fluorescence decay rate. Differences in the FAD and Ppy

average fluorescence relaxation times showed that the FAD composite with Ppy and Ppy effectively

quenched the FAD fluorescence and FAD could not freely unfold. The intramolecular electron transfer

took place between adenine and isoalloxazine moieties over the first 5 ps after the excitation. The findings

are very useful in the selection and adaptation of enzyme immobilization strategies, which are applied in

the development of biosensors and biofuel cells.

E-mail: d95642001@gmail.com

The human genome encodes four Piwi members, including Hiwi, Hili, Hiwi2 and Piwil3. Piwi is the germ

line-specific subclass of Argonaute proteins. The PIWI proteins family members have been demonstrated

to have essential roles in spermatogenesis in mice. Piwi gene null mice demonstrate loss of germ cell

phenotype and these phenotypes may be linked to high expression of retrotransposons. In this study, we

would like to investigate the expression of Piwi in human spermtogenesis by collection of discarded

azoospermia testes tissue from patient after IVF (in vitro fertilization) treatment.

Azoospermia is the medical condition of a male not having any sperm in their semen. It is associated with

very low levels of fertility, and azoospermia cases are idiopathic, since the molecular mechanisms

underlying the defects remain unknown. Azoospermia has two forms: obstructive azoospermia (OA),

where sperm are created, but cannot be mixed with the rest of the ejaculatory fluid due to a physical

obstruction, and non-obstructive azoospermia (NOA), where there is a problem with spermatogenesis,

this failure may occur at any stage in sperm production for a number of reasons. This situation may be

caused by genetic abnormalities.

We analyzed the mRNA expression level of Piwi in the NOA testis compare with OA testis by real time

PCR. Testes tissue from NOA group expressed significantly (P < 0.0001) lower Piwi levels than those

from OA group. Based on these data, we suggest that Piwi genes may involves spermatogenesis in human

testis.

1. Background

Balance is required for maintaining static or dynamic posture, performance of ADLs and moving around

safely in the community [1]. As balance is affected by the progressive loss of sensorimotor functioning

with increasing age [2]. Many researchers have suggested an evaluation method of balance for static state

[3,4,5], but these measures are difficult to relate to activity requiring dynamic balance. The aim of this

study was to develop a robust evaluation algorithm of dynamic balance using an inertial sensor and a

computational geometry technique known as a convex hull algorithm.

2. Results and Discussion

Table. 1 shows the average age and the postural stability score. There was a significant difference for the

postural stability score between the groups (p=0.011). The high score group have significantly less lower

balance function than low score group. Fig. 2 shows representative convex hull for five different ADLs

(a-e) of low and high score groups. Each pair (nx, ny) of represents a point in the xy-plane. This

difference showed a possibility that the developed stability index based on the convex hull algorithm

would be applied to an evaluation of balance.

Despite substantial progress in the study of cancers, important questions remain about the elucidation of

the relationship between the molecular origins of cancers and their resulting phenotypes. Network biology

is an integrative and systems-level approach for the interpretation of genome data, provides insightful

models for genetic phenomena, and sheds light on disease mechanisms via the identification of modules

perturbed in disorders. Deciphering the function of cancer-associated genetic variants is likely to get us

closer to achieving an understanding of cancer architecture that will ultimately be translatable into clinical

applications.

Cancers have been the first cause of death in Taiwan for 36 years. The number of deaths exceeded 48,000,

accounting for 28% of all Taiwanese deaths in 2017. Currently emerging big data techniques are

transforming medical science into a data science. Nation-wide collections of physician and hospital

claims data allow exploring the health state of an entire country’s population. Our studies integrated

systems-level molecular and genetic basis as well as population-based electronic health records (EHRs) in

Taiwan to discover cancer comorbidities.

In this work we constructed a cancer comorbidity network by EHR data and analyzed the structure of

comorbidity disease network stratified by gender and age. We also constructed a molecular disease

network and a protein-protein interaction network by public biobank datasets. Networks serve as a

paradigm for data integration and analysis, providing a systems-level understanding of the mechanisms

underlying diseases. With use of a variety of datasets, we inferred disease pathway and analyzed the

disease trajectory to understand the mechanisms in cancers. Understanding of the dynamics of

molecular-based network and population-based network may be helpful to elucidate potential biomarkers

of cancer progression and translate this knowledge about cancer pathogenesis for the development of

better strategies for the prevention, diagnosis, treatment and prognosis.

In order to increase the swine and poultry production, it’s commonly to raise animals in areas of

high-density population. Therefore, the infectious disease could spread easily and rapidly. Among the

infectious disease, viral diseases play a great role in yield reduction. This study was conducted to develop

antivirus agents based on probiotic Bacillus strains. For the purpose of screening of bacterial strains with

antiviral activity, 106 bacterial strains were isolated from the soil samples that obtained from the

Experimental Farm of National Taiwan University by using enrichment culture technique. The

cytotoxicity of these bacterial isolates toward baby hamster kidney (BHK) cells were determined. In

addition, the antiviral activities of these bacterial isolates were evaluated by using the Sindbis virus

screening approach, in which the inhibitory effects of these bacterial isolates against Sindbis virus (SBV)

replication in BHK cells were determined. Among these bacterial isolates, three strains (AC, CK, and LN)

showed low cytotoxicity and high antiviral activity and were further identified according to their

morphological and biochemical characteristics. The bacterial cultures of AC, CK, and LN were separated

into the extracellular supernatant, intracellular extract, cell wall fraction, and whole-cell culture, which

were determined their cytotoxicity toward BHK cells and human colon epithelial Caco-2 cells, and their

inhibitory effect against SBV replication in BHK and Caco-2 cells. In the BHK cell model, the

intracellular extract of CK showed no cytotoxicity but exhibited anti-SBV activity. In the Caco-2 cell

model, the extracellular supernatant, intracellular extract, and whole-cell culture of CK showed no

cytotoxicity but exhibited anti-SBV activities. The mRNA expression levels of antiviral factors, including

IFN-β, IL-6, MX1, and ISG56, of the virus-infected Caco-2 cells were further determined. The results

indicated that extracellular supernatant and whole-cell culture of CK significantly increased the IL-6

expression levels, intracellular extract of CK significantly increased the ISG56 expression levels, and

whole-cell culture of CK significantly increased the MX1 expression levels in the SBV-infected Caco-2

cells. Therefore, the inhibitory effect of CK against SBV replication in Caco-2 cells could be attributable

to the fact that CK could enhance the expression of cell-intrinsic antiviral factors. These results suggested

that CK might have a potential to be developed as feed additives with antiviral activity.

Development Headquarters, Milbon Co. Ltd., Japan

E-mail: ksuzuta@milbon.com

Abstract

Bleaching is one of hair-decoloring techniques widely used in the beauty treatment. Since hydrogen

peroxide is used in this process, disulfide bonds in proteins are oxidatively cleaved and cysteine residues

are converted to cysteic acid residues. Increased cysteic acid is considered to be a major cause of hair

damages. Infrared (IR) spectroscopic measurement has been a mainstream up to now for evaluation of

cysteic acid. However, since the spectral peak derived from cysteic acid detected by IR spectroscopy is

small, so it is difficult to argue the generation behavior further in detail. In this study, by analyzing the

chemical structural state of hair sulfur atom by X-ray absorption fine structure (XAFS) measurement

using synchrotron radiation X-ray microbeam, we have discussed the generation behavior of cysteic acid

within hair cortex compared with IR spectroscopic method. It has been found out that cysteic acid

generation in hair cortex is diffusion-controlled because the amount of cysteic acid obtained by both IR

spectroscopic method and XAFS measurement increases linearly with square root of bleaching time. This

result of XAFS measurement strongly supports the proposed diffusion model that the diffusion-controlled

behavior for cysteic acid generation in the cortex is caused by controlling the diffusion of hydrogen

peroxide from cell membrane complex into cortical cell. In addition, the deviation from this linearity has

been observed in the long-time bleaching samples from a result of XAFS measurement, and it has been

suggested that the reduction of cysteic acid due to the protein outflow from hair is additively detected.

From this result, it is considered that XAFS measurement has higher sensitivity than IR spectroscopic

measurement in evaluation of cysteic acid in hair cortex.

1. Background

Pestalotiopsis microspora NK17 is an entophyte that is capable of producing amount of secondary

metabolites, such as taxol, one of the widely prescribed anticancer drug. Analyzing the metabolic

profiling may be helpful to improve the production of Taxol.

2. Methods

High performance liquid chromatography (HPLC) was used to detect the fermentation products and then

purified by semi-preparative HPLC. The structure of these compounds were elucidated by NMR

(containing 1H-NMR,

13C-NMR, HSQC and HMBC). To explore the biosynthesis of them, metabolites in

the strains carrying individual deletion of the 36 PKS genes in NK17 were analyzed by HPLC.

3. Conclusion

Four more dibenzodioxocinone derivatives in the liquid culture of the isolate NK17, i.e. pestalotiollide C

(2), 1’,2’-dehydropenicillide (3), 3’-methoxy-1’2’-dehydropenicillide (4), and a new metabolic product,

1’,2’-epoxy-3’,4’-didehydropenicillide (5) were defined. Interestingly, all the four compounds share the

same carbon skeleton of pestalotiollide B (1), a characterized dibenzodioxocinone derivative. Results

showed that deletion of pks23, pks37 and pks45 led to a significant decrease of compound 1 and 3, while

deletion of pks24, pks34 and pks39 led to a significant decrease of compound 2 and 4. Deletion of pks28

and pks1 could reduce the production of compound 1 and 4, respectively. The addition of side chains of

the compounds were deduced. The data may help to illustrate the biosynthesis of dibenzodioxocinones

and help to create new CEPT-inhibitors in fungi.

Abstract

The effects of temperature on the decolorization kinetics of methylene blue for photo-fenton using

Fe-diatomite were studied at 25, 55 and 75C. The chemical compositions of Fe-diatomite were analyzed

by X-ray fluorescence. The surface area, pore volume and average pore diameter were determined by

BET method. The photo-fenton process follows pseudo first-order reaction in the first stage. The linear

relationship between ln C/C0 and reaction time (t) was obtained. It was seen from the result that the

decolorization rate constants (k) decreased with the increasing temperatures because of the accelerated

decomposition of H2O2 into water and oxygen. The reaction activation energy (Ea) was -2.97 kJ/mole.

1. Background

Biomass energy, or bio-energy, refers to renewable energy by converting biomass, and is the most

available resource on Earth, as it is a value energy product that can replace depleting fossil energy.

Biomass mainly consists of cellulose, hemicelluloses, and lignin, with cellulose content about 40~50%,

hemicelluloses content about 2~30%, and lignin about 5~20 %. After conversion, biomass can be

prepared into liquid, gas, and solid fuels. For the increasingly scarce fossil fuels, biomass energy is an

important resource. Another purpose of this study is to develop a computer simulation model for the

bubbling fluidized bed biomass gasification process that can accurately forecast the various operational

conditions of the gasification furnace. The development of the original model uses the ASPEN

PLUS-based Gibbs free energy minimization.

2. Methods

According to the gasification process, when using ASPEN PLUS to establish the model for a bubbling

fluidized bed biomass gasification furnace, the DRY-REAC (using the reactor RSTOIC model) and

DRY-FLSH models are combined to simulate the drying process. The DECOMP model uses the RYield

reactor model to simulate the pyrolysis process of biomass decomposition (non-conventional components

are broken into elements and ash). The GASIFIER model uses the RGibbs reactor model to simulate the

gasification process, the RGibbs reactor model uses Gibbs free energy minimization, and the SEPRATOR

model uses the SSplit Fractions model to separate syngas and ash. The ASPEN PLUS-based bubbling

fluidized bed biomass gasification furnace model

3. Results

The simulation results found that CO2 content decreased with rising gasification temperature; however,

the H2 and CO contents increased, while the CH4 content changed little. In addition, with the rising ER

value, the CO, H2, and CH4 contents decreased while the CO2 content increased. The results are consistent

with Narváez et al. (1996), who used pine sawdust in a bubbling fluidized bed for gasification. Simulation

results proved that the ASPEN PLUS-based bubbling fluidized bed biomass gasification model can

accurately simulate the bubbling fluidized bed’s biomass gasification process with relatively better

reliability and applicability.

1. Background

Mercury is a highly toxic pollutant. Inorganic mercury can be converted into methyl mercury, and easily

accumulates in living organisms by contaminated drinking water, food chain and soil. An optical chemical

sensor (optode) is a device that is interesting in determination of mercury because of fast, low cost, and

simple monitoring. Moreover, the detection by optodes allows visualization of color changes by the naked

eye, which makes them suitable for on-site detection. Therefore, the objective of this research is to

develop a paper-based cation-selective optode sensor or paper strip as an instrument-free and portable

device for on-site detection of Hg2+

in water samples.

2. Results

The response of the paper strip relies on cation-exchange equilibrium between the aqueous solution

containing Hg2+

and the sensing paper. CU1 induced the extraction of Hg2+

from aqueous solution into the

sensing paper by formation of a coordinated compound. To maintain an electroneutrality of the system,

hydrogen ions of chromoionophore XIV are released from the sensing paper at the same time. Therefore,

the color of paper strip turns from blue (CH+) to yellow (C). The ion-exchange process is expressed by Eq.

1,

(1)

where L and R- are CU1 and KTpClPB, respectively.

The paper strip responded to Hg2+

by changing in color from blue to yellow at pH 5.0 with a response

time of 15 min. The sensor showed excellent selectivity toward Hg2+

over interfering ions including Na+,

Mg2+

, K+, Ca

2+, Cr

3+, Fe

3+, Co

2+, Ni

2+, Cu

2+, Zn

2+, Cd

2+ and Pb

2+. Only Ag

+ can interfere by changing in

color from blue to yellow. However, this interference can be easily eliminated by AgCl precipitation. The

response of the paper strip has usual sigmoidal shape, adjusting the data set to a Boltzmann equation2 with

R2 = 0.9990. The dynamic range went from 6.6×10

-7 M to 5.0×10

-5 M, and the limit of detection (LOD)

calculated with this method was 0.66 µM (0.13 ppm, n=10) which was closed to LOD of Hg2+

detection

calculated from conventional planar film optode3. However, this proposed method was not required any

instruments and provided an easily detection method for on-site analysis. Finally, the paper strip was

successfully applied to determine Hg2+

in real water samples including drinking water, tap water and pond

water with the recovery of 82-119% and %RSD less than 11%. The results are in satisfactory agreement

with those obtained by inductively coupled plasma spectrometric measurements (ICP-OES).

Abstract

Cu2Sn3S7 (CTS) can be used as the light absorbing layer for thin-film solar cells due to its good optical

properties. In this research, the powder, baking, sulfur, sintering (PBSS) process was used instead of

vacuum sputtering or electrochemical preparation to form CTS. During sintering, Cu and Sn nanopowders

mixed in stoichiometric ratio were coated to form the thin film precursor. It was sulfurized in a sulfur

atmosphere to form CTS. The CTS film metallurgy mechanism was investigated. After sintering at 500

°C, the thin film formed the Cu2Sn3S7 phase and no impurity phase, improving its energy band gap. The

interface of CTS film is continuous and the formation of intermetallic compound layer can increase the

carrier concentration and mobility. Therefore, PBSS process prepared CTS can potentially be used as a

solar cell absorption layer.

1. Background

When the inversion layer occurs in the atmosphere, the diffusion of airborne pollutants is limited and air

quality becomes poor. The inversion occurrence and profile of atmospheric temperature around the

discharging chimneys is necessary to be monitored for pollution reduction and environmental governance.

The popular methods used to collect meteorological data are through monitoring by air balls or an

inversion thermometer. Compared with the aforementioned equipment, using unmanned aerial vehicles

(UAVs) combined with sensors (Martin et al., 2011; Gonçalves and Henriques, 2015) is inexpensive and

effective to operate and move according to the results of this study.

2. Methods

First, mount the module of sensors on the top of the multi-axis UAV. The module included sensors of

temperature, relative humidity, PM2.5, GPS, bluetooth transmission, and data logger and processor.

Second, allow the UAV to rise vertically to collect and transfer meteorological data and PM2.5

concentration at controlled altitude levels near the selected chimneys. Finally, the collected data can be

quantitatively rendered in ten minutes.

3. Results

Figure 1 showed the trend of atmospheric temperature and airborne PM2.5 concentration near the

chimney of a steel plant with increasing altitude. The vertical height of this chimney located at altitude of

4.6 meters is 143 meters. The monitoring time was around 8 o'clock at night and its relative humidity was

about 75%. Inversion phenomenon of atmospheric temperature occurred at heights of 192, 235, and 270

meters. It was shown that the dispersible height of the discharged pollutants, such as PM2.5, from this

chimney and the surface only reached to 192 meters. At altitudes in 300 meters, there were multiple

inversion layers detected in time using our method. By immediate alert of inversion layers around the

discharging pipes of factories, effective reduction and impact control of pollution emissions can be

achieved.

1. Background

Over the last decades, the interest in transition metal nanocatalysts has significantly increased because

they can use in numerous fields of chemistry. The broad applicability could be attributed to outstanding

properties of nanomaterial including quantum effect, unexpected chemical, optical, mechanical, electrical

and magnetic property.1 These properties offer researchers the chance to advance the catalytic activity and

stability of nanocatalyst. Since silver nanomaterials have unique properties such as stability, lower cost,

antibacterial activity and higher speculative open circuit potential, those nanomaterials have been widely

used as a catalyst. Furthermore, silver nanomaterials with various size and shape showed an enhanced

catalytic activity in an oxidation of organic matter, epoxidation of alkenes, and photocatalytic reactions.2

2. Results

Figure 1 shows the SEM images of silver nanomaterials prepared by using silver nitrate and different

reducing agents. The resulting Ag nanomaterials reduced by a sodium borohydride were formed in the

shape of a sphere. Figure 1 (a) image shows unclearly sphere shape of Ag nanoparticles, therefore, we

measured TEM and high-performance FESEM so as to obviously obtain a shape of Ag nanoparticles in

Figure 3. At this time, the ionic liquid which acts as both co-solvent and surfactant led to smaller and

more orderly Ag nanoparticles. In order to determine the role of an ionic liquid, Ag nanoparticles were

synthesized without ionic liquid in the presence of sodium borohydride as reducing agent (Figure 1 (b)).

As shown in Figure 1 (a-b), the SEM images clearly show that the average diameter of Ag nanoparticles

without ionic liquid is approximately 98 nm, which are twice as big as Ag nanoparticles using ionic liquid.

Also, in order to verify an effect of reducing agent, we changed the reducing agents such as sodium

borohydride and hydrazine hydrate in same reaction time and temperature. When hydrazine was used, the

Ag nanoparticles were formed in shape of plates with broad size distribution in Figure 1 (c).

We successfully achieved the Ag nanocatalysts with different size and shape in ionic liquid media. The

shape of these catalysts were controlled by using different reducing agents, in actually, Ag synthesized

using sodium borohydride was formed in a shape of sphere for 0.5 h at room temperature. Furthermore,

the hydrazine hydrate as reducing agent built Ag hexagonal plates with indeterminate plates in small size

for 12 h at room temperature. In this synthetic method, the ionic liquid which acts as both co-solvent and

surfactant led to smaller and more orderly Ag nanomaterials. The resulted Ag catalyst exhibited

photocatalytic activity in MO oxidizing as a reaction of water purification under natural sunlight and

visible light (Xe-lamp) irradiation.

1. Background

The demand for wearable devices has increased exponentially in recent years. Stretchable conductive

textiles are an important element in next-generation wearable device [1]. Conductive textiles can be used

as sensors for monitoring human motion through changes in the electrical resistance to varying strain

rates.

2. Methods

In this study, we propose a water-based MWCNTs (multi-walled carbon nanotubes) ink and a

vacuum-filtration process. MWCNTs have excellent electrical conductivity and mechanical strength and

is cheaper than other metallic materials. The vacuum-filtration process is simpler and cheaper than other

manufacturing methods. The textile used to prepare the conductive textile consisted of 93% polyester and

7% polyurethane. Conductive threads were used to form the electrical contact points for measuring the

electrical resistance. The conductive textile prepared by the vacuum-filtration method was attached to the

finger joints of a glove to form a motion-sensing glove. Thermogravimetric gravimetric analysis was

performed to investigate the thermal stability of the MWCNTs before and after oxidation. The defect

variations in the MWCNTs before and after oxidation were confirmed by Raman spectroscopy, and

field-emission scanning electron microscopy was used to examine the morphology of the conductive

textile samples. A stretch evaluation system was constructed to measure the variations in electrical

resistance according to changes in the length of the conductive textile; the stretch evaluation system

consisted of a bending machine and a digital multimeter.

3. Results

The conductive textile prepared by vacuum filtration was evaluated for resistance variations as it was

subjected 10,000 cycles of repeated stretching at strain rates of 0% to 20%. The samples showed good

results with resistance changes of less than ± 3% after 10,000 cycles of stretching. This result

demonstrates that the conductive textile prepared by the vacuum filtration had excellent durability. The

pulse of the resistance variation was uniform, which means that this textile can be applied as a reliable

resistance displacement sensor. A motion-sensing glove was fabricated with the conductive textile

prepared by vacuum filtration. The pulse of the oscilloscope changed accurately according to the

movements of the fingers, demonstrating that the conductive textile prepared in this study can be applied

to motion sensing in real products.

* E-mail: benedicto@gachon.ac.kr

1. Background

The lithium metal battery has attracted much attention as the ultimate lithium secondary battery for high

energy density. However, safety issues and battery performance deterioration due to the growth of lithium

dendrite have hampered the practical use of lithium metal batteries. Recently, lithium fluoride has been

considered as a lithium metal protective layer to solve this problem. In order to form lithium fluoride as

an artificial SEI, coating methods such as deposition [1], liquid reaction [2], and gas reaction [3] are

applied on the surface of lithium metal.

2. Methods

In this study, lithium fluoride was deposited on lithium metal using thermal evaporation method to inhibit

dendrite formation. Thermal evaporation is advantageous in that the deposition rate is faster than that of

sputtering or other deposition methods and the impact applied to the substrate is weak. To verify the

characteristics of lithium metal batteries according to the thickness of lithium fluoride, lithium fluoride

was deposited to the thickness of tens to hundreds of nanometers. To confirm the electrochemical

properties, the symmetric cells (Li│Li) were fabricated to evaluate the time-dependent impedance

change and the potential change over time under the condition of 1 mA/cm-2

and 1 mAh/cm-2

. The Li│

LiCoO2 cells were fabricated by applying LiCoO2 cathode material, which is widely used in industry, and

the stability change according to application of lithium fluoride was evaluated. In addition, the surface

morphology according to the application of LiF was compared through SEM analysis.

3. Results

EIS analysis according to the time and cycle progress showed that the impedance change of bare Li cell

was larger than LiF-coated Li cell. In the cycling stability evaluation using the symmetric cells,

LiF-coated Li cell showed more stable characteristics than bare Li cell at current density of 1mA/cm2.

The SEM images showed that lithium grows roughly on the bare Li metal and the surface morphology of

the LiF-coated Li metal is relatively smooth. In Li│LiCoO2 cells cycling evaluation, LiF-coated Li cell

showed more stable cycle performance than bare Li cell and suggested possibility for practical use.

1. Background

Wind power plays an important role in the renewable energy development of Taiwan. It is disclosed from

the government planning reports that wind farm development, related standards & design verifications,

and the operation & maintenance of wind turbine are important issues that should be studied carefully. In

addition, those issues are related closely to the reliability engineering and statistics. To this end, this study

intends to apply the reliability engineering to the development of wind power industry. However, in this

stage, analysis of collected wind data with statistics and reliability techniques is the major task.

2. Methods

Several well-known probability density functions (PDF) including Normal, Log Normal, Weibull,

Rayleigh, Gamma, Bimodal Mixture Weibull are chosen to best fit the wind-speed data in this study. In

the estimation of parameters for each probability density function, the maximum likelihood (ML) method

is used. To better understand the characteristics of wind such as the wind direction and its associated wind

speed, which is crucial to the design of single wind turbine tower as well as the deployment of a set of

wind turbines, the rose diagram is adopted and drawn. The wind power density that is a quite important

indicator for developing the wind farm is also evaluated. In addition, the turbulence intensity (TI) which

can be quantified with the wind data and the normal turbulence model is calculated to help the design of

the wind turbine.

3. Results

In the present study, works carried out and results obtained based on collected wind data of a particular

wind farm in Taiwan are summarized as follows. (1) Fitting of wind-speed by several probability density

functions. (2) Construction of wind-rose diagram and evaluation of wind power density. (3) Investigation

of wind-speed variation in different elevations. (4) Disclosing the joint probability density of wind-speed

and wind-direction. (5) Preliminary investigation of extreme wind speed in consideration of Gumbel’s

order statistics. (6) Investigation of turbulence intensities and examination whether the result is in

compatible with the specification of IEC 61400. The conclusion in this stage is that a bimodal mixture

Weibull distribution can better describe the wind speed of the particular wind farm than Weibull

distribution which is frequently used in specifications and the design of wind power systems. It is also

found that, as predicted from aerodynamics, wind speed does increase along with elevation, but the

distribution style remains similar. If a 50-year return period is considered, it is found the expected

extreme wind speed is 46.5 m/s. It is also concluded that turbulence intensities of the wind farm are in

compatible with that required by IEC 61400. It indicates that the wind farm is worth being developed.

Abstract

Power facilities are important social infrastructures, and they must maintain their functions even in the

event of a natural disaster. As power supply is required for swiftly carrying out reconstruction projects

made necessary by the occurrence of natural disasters like earthquakes, the seismic stability of power

facilities is very important. In this study, the seismic performance of the cable termination facility, a

power facility, was evaluated using the shaking table test. In addition, the results of the shaking table test

were applied to a finite element model for the conduct of seismic response analysis. The maximum stress

values obtained from the shaking table test and finite element analysis were lower than the allowable

stress of the material and met the acceptance criterion suggested by IEEE Std. 693:2005. Furthermore, the

finite element analysis showed maximum stress values higher than those obtained from the shaking table

test. Therefore, it was confirmed that the seismic safety of cable termination facilities can be evaluated

using finite element analysis.

1. Background

Solar power is a key development for the purpose of the global sustainability trends in renewable energy

but raises level of uncertainty in power systems. However, influenced by factors of geography and

circumstance, the solar power has the characteristics of intermittency and uncontrollability. Therefore, the

study of solar power forecasting technology for assisting power system operation is becoming important.

The solar power forecasting is an important measure to solve this problem and to ensure the reliable

operation of a power system which is significantly fed. Power dispatch plays a very important role for

better decisions in system and to secure the reliable and stable energy supply. The solar power forecasting

is an important for power system and helps to improve the reliability and also reduces the generation cost.

2. Results

The RBFNN has the capability of dealing with varied and complicated relations between input and output

data, and Particle Swarm Optimization (PSO) helps with the appropriated regulation of weighting

parameters to improve the forecasting results. In addition, proper parameter settings of RBFNN is

important to its efficiency and accuracy. In this paper, use the PSO to perform the parameter optimization

for RBFNN, which not only improve the solar power forecast model availability and improve the

forecasting accuracy. Simulation results provided a short-term solar power forecasting and demonstrated

the effectiveness of the proposed method in a volatile environment. RBFNN has the capability of dealing

with varied and complicated relations between input and output data, and PSO helps with the

appropriated regulation of weighting parameters to improve the forecasting results. The data of solar

power were used to demonstrate the performance of RBFNN and PSO and integrated historical data and

central meteorological bureau data to forecast solar power. For case study, it proved that RBFNN and

PSO have the capability to produce better results for volatile solar power forecast.

1. Background

Robusta coffee is one of popular agricultural crops, especially in southern Thailand. Normally, Robusta

coffee is internationally traded as green coffee bean, which is produced by dry processing. From dry

process, it provided the unwanted material which was mixed into the green coffee bean such as parchment

coffee (Prata & Oliveira, 2007). Parchment coffee separation from the Robusta green coffee bean is the

important process because it can increase the value of Robusta green coffee bean. It can also decrease the

problem in the coffee processing especially roasting process. Therefore, the objective of this work was to

investigate the effects of sieve angle and air velocity on the separation efficiency of parchment coffee

from Robusta green coffee bean using pneumatic separation machine combined with vibrating sieve. The

loss percentage, weight purity index and specific energy consumption (SEC) were also investigated.

2. Results

The experimental result showed that the pneumatic separation combined with vibrating sieve can help the

separation efficiency to be higher due to the vibrating sieve provided the good distribution of materials

(Delaney et al., 2012). The air can easily blow through the materials. The air velocity and the sieve angle

significantly affected the performance of pneumatic separation machine combined with vibrating sieve.

The separation efficiency, loss percentage, weight purity index were higher with increasing air velocity.

The higher air velocity provided the parchment coffee to be easily removed, leading to higher separation

efficiency and weight purity index. However, the green coffee bean was more blown out to the parchment

coffee tray when increasing air velocity. Therefore, the loss percentage was also higher. In addition, the

increase of air velocity provided the increase of SEC value. This is because of higher energy requirement

value. In term of sieve angle, the increase of sieve angle provided the lower value of separation efficiency,

loss percentage, weight purity index as well as SEC. The higher sieve angle provided the faster movement

of materials (Kannan et al., 2016), leading to the shorter time for separation and resulting in the lower

value of separation efficiency, loss percentage, weight purity index and SEC.

1. Background

Hyaluronic acid (HA) or hyaluronan is one of the glycosaminoglycans that consists of repeating units of

N-acetyl-D glucosamine along with glucuronic, which is linked by glycosidic bonds [1]. HA is a linear

and high molecular weight polysaccharide. In cosmetic products, HA has been utilized due to viscoelastic,

free radical scavenging properties and good biocompatibility [2]. In addition, the concentrations of HA

added in cosmetics are up to 1% [3]. Therefore, the determination of HA in cosmetic samples is

necessary because it helps for quality control of products in both manufacturing process and the markets.

The aim of this study is to develop a simple capillary electrophoresis (CE) method for determination of

HA in cosmetic samples.

2. Results

HA was detected from cosmetic samples, which diluted to 100 times with 10% v/v BGE. The results

showed good separation because of no matrix to interfere the signal of analyte. The analysis time was

achieved at approximately 8.5-8.7 min. For quantitative analysis of HA, the standard addition method

was used to construct a calibration curve, which was in the ranges of 50-250 mg L-1. Limits of detection

and quantitation of the proposed method for determination of HA were 1.0 and 3.0 mg L-1

, respectively.

In addition, intra-day (n=5) and inter-day (n=3) precisions were investigated and found that the

percentages of relative standard deviation of the corrected peak area at 60, 120 and 180 mg L-1 HA were

0.8, 0.9 and 1.9% (for intra-day) and 3.1, 3.4 and 6.5% (for inter-day), respectively. The developed

method was applied for determination of HA in cosmetic samples and found that the recovery percentages

of HA were in the range of 80.5 to 91.6%, indicating high accuracy of the method. Therefore, the

developed method was reliable and simple without complicated sample preparation. Moreover, this

method can be possibly applied in cosmetic industry for quality control of products.

Abstract

Acoustical measurements and recordings were made during 15 lectures in 11 university classrooms at

Kangwon National University in Korea. A statistical method modified by Sato and Bradley (2008, JASA)

was used for obtaining octave band speech and noise levels in university classrooms during lectures. In

the 11 active university classrooms the students experienced: speech levels of 51.5 dBA (s.d.=2.7 dBA),

noise levels of 44.3 dBA (s.d.=2.1 dBA), and a speech-to-noise ratio of 7.2 dBA (s.d.=2.7 dBA). The

results showed that the speech and noise levels were 0.7 dBA higher and 0.1 dBA lower than in the 11

UBC classrooms (Hodgson et al, 1999).

E-mail: mychang@niu.edu.tw

1. Background

In the past decade, the egg industry suffers severely labor shortage in Taiwan. Although the egg

washing/packing automation system had been introduced into some large companies, egg shipping boxes

are still moved onto pallets by porters. A porter may move up to 2 or 3 tons of goods per day in a

commercial egg packing factory. This work is heavy and harmful to the porters. Automation using robot

might be a feasible way to replace human. In order to satisfy the different customer’s need, various

products with various shipping boxes and their corresponding pallets, and even the piling methods, will

coexist in the egg packing production simultaneously. The product diversity makes the automatization

complex and difficult because it conflicts with the golden rule “standardization” and “simplification”. The

objective of this research was to develop an automated flexible transportation system for egg shipping

boxes to overcome the overcome the problem.

2. Methods

This study develops an automated flexible transportation system for egg shipping boxes. The system was

divided into four major parts: (1) a new conveyor was set up to transport the egg shipping boxes form the

packing lines to the pallet area. (2) A product identification station was located on the conveyor in front of

the pallet area. This station detected the RFID tags on the shipping boxes, identified the type of products

and its corresponding setting weight, and sent the command to robot to move and pile this boxes. (3) A

robot moved the boxes to the assigned pallets based on the type of product. The unqualified boxes would

be bypass by the robot and be conveyed to the inspection area at the end of conveyor. The worker would

recheck the contents in the unqualified boxes.

3. Results

The intelligent flexible transport system was set in a commercial egg factory with 16 egg packing lines

and the production capacity of 400,000 eggs/day. This system was designed to manage the transportation

of eight different type of shipping boxes on four different size of pallets and 14 corresponding piling path

of robot. In each batch of production, the robot would handle three different types of product to their

assigned pallets. The transport capacity of the robot should be more than 240 boxes per hour, or 2,000

boxes per day, almost equal to 8 to 10 workers. This system alleviate the urgent manpower requirement

and the reduce risk of occupational injury in egg packing factory. It will also provide an inspection

mechanism to detect the human error in the box-packing process.

1. Background

The elevated jet in crossflow (the transverse jet) has been studied extensively because of its widespread

applications, for instance, combustion, mixing, cooling, stack flare, and propulsion devices (e.g., Pratte &

Baines 1967, Fric & Roshko, 1985). The mixing of jet with crossflow played a major role in the

applications. The acoustic excitation to the jet was used in the present work to study the characteristic

flow behaviors and mechanism for mixing enhancement.

2. Results

Figure 1 shows typical instantaneous flow patterns in the median plane of the non-excited elevated

transverse jet at the jet-to-crossflow momentum-flux ratio R = 1.2 obtained by the laser-assisted

smoke-flow visualization technique. A clear counterclockwise-rotating vortex train appears on the upwind

shear layer of the deflected jet after the jet left the tube-tip. This vortex train does not appear stably. It

appears intermittently and disappears sometimes without periodicity. This type of flow structure occurs at

R > 1. The deflected jet column near the tube exit is coherent. The jet fluids start to disperse and expand

appreciably as the jet column is bent over. The natural-state of the shear-layer vortices does not cause

large dispersion of jet fluids. Figure 2 shows the flow pattern in the median plane of the transverse jet

excited by the sound waves at an off-resonance frequency. The crossflow impingement deflects the jet

column near the tube exit. The jet fluids in the downstream area present large up-down oscillating

motions. The frequency of the bent jet oscillation is synchronized with the forcing frequency of the

acoustic excitation. The jet pulsations induce back-and-forth flapping motions of the jet column near the

tube exit. As the jet column near the tube exit tilts up, a vortex is induced downstream of the tilting jet.

The periodically created vortices propagate downstream and cause the deflected jet to oscillate. The

flow-visualization pictures shown in Fig. 3 are for the resonance frequency excitation, which presents

crowded puffs as the jet column near the tube exit is flapping back-and-forth quickly. The puffing

frequency is the same as the resonance frequency. The large excitation intensity at the resonance

frequency makes the jet flow penetrate to high elevation and hence the spread of the smoke in the

transverse direction looks wider than that in Fig. 2. The measurements of carbon monoxide concentration

show significantly higher mixing efficiency than that of the non-excited transverse jet as the jet is

acoustically excited, particularly excited at resonance frequency.

Abstract

The paper presented the propagation characteristics of graded phononic crystals with smart material. The

acoustic waveguide characteristic of the graded phononic crystals is used to design some novel acoustic

devices and the composite system combined with graded phononic crystals structure. Besides, the graded

phononic crystal system is composed of circular cylindrical with air background in this study.

At first, the effective refractive index of the phononic crystal system can be tuned by adjusting the filling

ratio because that periodic structure behaves like a homogeneous medium, since dispersion relation is

almost linear in long wavelength limit assumption. Then, the plane wave expansion method is utilized to

calculate the band structures of the graded phononic crystal. Thus, the effective refractive index of the

graded phononic crystal with various filling rations can be obtained. The smart materials can be used in

graded phononic crystal structure to design more effective acoustic waveguide devices. Additionally, it

also can be adopted to study other types of graded phononic crystal devices with various smart materials

based on the numerical and experimental results of this paper.

1. Background

Urbanization and its overcrowding has changed disaster environment by spreading the urban area to the

steep slope (or mountain slope) and the reservoirs that had existed in the rural area in the past. Collapses

of those steep slopes of the mountains and the reservoirs are likely to cause a wide range of complex

disasters. Those should be considered by preliminary disaster impact assessment at a stage of urban

development plan. However, the preliminary disaster impact analysis has been performed only for single

disasters, not complex disasters. It is only dependant on qualitative judgment of the committee members.

This study mainly performed some precedent research on the development of GIS-based risk management

tool for multi-disasters induced by landslides and ole reservoir collapse.

2. Results

This study was performed with a purpose of developing a GIS-based complex disaster risk assessment

tool estimating the losses from multi-disasters caused by steep slope landslides and old reservoir collapses.

It is mainly supposed to firstly develop risk assessment criteria to identify whether there is a need for risk

mitigation, to develop cost-benefit analysis tool to judge whether t is an acceptable risk or not, to identify

GIS-based qualitative/ quantitative risk analysis tools, and then to estimate loss. Through these processing,

an amount on the damages induced by multi-disasters can be finally estimated. Based on these steps, it

can be expected that the risk assessment and management for slope landslides and the collapse of old

reservoirs is performed in both qualitative and quantitative way.

* E-mail: dhlee2864@gmail.com

1. Background

The scale of natural disasters has been recently increasing due to climate change and rapid urbanization.

Their characteristics have become complex by combination of natural disaster and substantial social

disasters (Agusomu and Paki, 2011). Those complex disaster have defined as cumulative-disaster and the

increasing damages induced by the cumulative-disasters are resulted in the growth of interest in risk

assessment and management for cumulative-disasters (CRED, 2013). Since the cumulative-disasters have

occurred as a result of multiple or simultaneous natural disasters and social disasters, as a first step to

assess the risk of the cumulative-disaster, it is essential to analyze the causal and reliance between

disasters (Farrokh Nadim and Zhongquang Liu, 2010). Therefore, this study mainly analyzed the

reliance between single disasters for the risk assessment of cumulative-disaster. This is evaluated by

establishing a scenario of complex disaster and assessing the risk of cumulative-disasters based on their

reliance.

2. Results

This study mainly assessed the risk of cumulative-disaster by using the Delphi technique. Fistly, the

reliance of single disasters are calculated and the virtual scenario is established. Finally,we proposed a

new method for assessing the complex risk due to cumulative-disasters using the reliance on

inter-disasters. The risk assessment method is specified and supplemented in consideration of frequency

and intensity of disasters. In the future, we will improve and extend the scenario by raising the reliability

of the group of specialists surveyed by each disaster.

E-mail: takaaki.okamoto@water.kuciv.kyoto-u.ac.jp

Abstract

At the time of localized torrential rains, wood on a mountain surface is washed onto rivers and these

driftwood in rivers aggravate the flood events. For example, large driftwood blocks the river, which lead

to increased water levels and flooding of the nearby areas. Therefore, some previous researchers have

investigated the driftwood capturing structure to remove woody debris from the river.

In the present study, we considered the driftwood capturing structure by using an anti-flood pond. The

laboratory flume experiments were conducted and we investigated the driftwood trapping probability in

the anti-flood pond. The results indicated that the trapping probability is highly influenced by the groyne

position.

Taipei, Taiwan

* E-mail: mwwu@ntut.edu.tw

1. Background

Powder metallurgy (PM) technique is a versatile process to economically fabricate metallic materials in

mass production. However, the presence of pore, which impairs the mechanical performances, in the PM

materials is the most important issue to overcome. In general, the porosity of the PM steels ranges from 5

vol% to 15 vol% [1,2]. The pore acts as a stress or strain concentrator and leads to inferior mechanical

properties [3]. Unfortunately, the effects of the pore and the microstructure on the strain distribution have

not been clearly studied to date. The objective of this study was thus to investigate the influence of

microstructure and pore feature on the partition of strain during tensile testing. Two PM steels including

pure Fe and Fe-0.43C were analyzed in this study.

2. Results

The microstructure of the pure Fe specimen was fully ferrite, and the porosity was 10.9 vol%. The pores

in the Fe sample were very irregular and large. From the DIC strain mapping of the Fe sample, it is clear

that the strain concentrated at the original powder peripheries and sintered necks. The strain gradually

extended into the powder interior with the increase in the tensile stress. Ductile fracture on the sintered

neck was definitely identified by SEM. On the other hand, the microstructures of the Fe-0.43C steel were

ferrite and pearlite, and the porosity was 11.2 vol%. In the Fe-0.43C steel, the strain was also

concentrated in the ferrite. No obvious strain in pearlite could be found. The fracture surface/path also

indicates that the pores near ferrite was the dominant fracture site in the ferrite/pearlite steels. This results

also proves that the presence of pearlite in the steel can increase the tensile strength of the steel, though

the ductility was degraded. Therefore, the strain and fracture were non-uniform and were localized in the

ferritic area. In conclusion, DIC technique was very useful for evaluating the microstructure responsible

for the strain and provide valuable information for microstructural design of PM steels.

Mao Zedong during the Rectification Movement in the Yan’an Period

Wei-Li Wu

Air&Sea Logistics and Marketing Department, Taipei University of Marine Technology, Taiwan

E-mail: Weiliwu@mail.tcmt.edu.tw

1. Background

“The east is red as the sun is rising. China has brought forth Mao Zedong.” Mao Zedong is a legend in

modern Chinese history. He rose from an assistant librarian to the leader ruling over China within a few

decades, dominating the destiny of hundreds of millions of people. Reflecting upon Mao’s political career,

he displayed military talents early on, but was excluded by the Bolsheviks who returned from the Soviet

Union. However, during the Long March, he regained military power because of his correct military

strategy. With respect to the power of the party, he had been locked in a struggle with the

“Internationalists,” and it was only until the early Yan’an period that reversal of events became unlikely.

However, “with power to spare we must pursue the tottering foe,” Mao relentlessly pursued and attacked

Wang Ming who refused to make self-criticism. At the time when thinking was yet to be united, Mao

launched the “Rectification Movement” with the aim to overhaul the high-level leadership within the

party, and “seizing this opportunity” to spearhead the campaign to grassroots. After this “spiritual”

cleansing, “Mao Zedong Thought” came to reign supreme in the party, which was like a rehearsal of the

“Cultural Revolution” many years later. Mao, through this campaign, firmly gripped the party, as well as

political, and military powers. This study takes the “Rectification Movement” as the background, and

attempts to clarify the theoretical foundation and means of Mao with a view to establishing the

relationship between Mao Zedong and the “Rectification Movement.”

2. Conclusions

The Yan’an Rectification Movement was the key that Mao was able to concur the whole country, and

smile proudly with his position as secure as Mount Tai after the establishment of the People’s Republic of

China. The campaign model of the Yan’an Rectification Movement also influenced the operation of the

political movements in subsequent decades. Such influence could hardly be over-emphasized.

In the Yan’an Rectification Movement, through his own learning and innate personality, Mao employed

many tactics and means. With the conclusion of the Rectification Movement, Mao obtained immense

power that fused together the military and the party, similar to the nuclear fusion that was about to

produce formidable power. Mao at this time had become every inch a “sage-philosopher” in the eyes of

Edgar Snow, like a never falling red star that shone over all of China.

Public Communication of Green Energy and Low Carbon Technology - A Study on the

Propaganda for National Renewable Energy Policy in Taiwan

Cheng-Neng Lai

Department of Public Relations and Advertising, Shih Hsin University, Taiwan

E-mail: layjn@mail.shu.edu.tw

Abstract

Taiwan relies on imports for up to 98% of its energy because lack of energy resources. In addition to the

worries about nuclear energy, renewable energy has become the most popular and important solutions in

the world in recent years. Although there are more than 70% of Taiwanese support to use renewable

energy, the relevant policies and infrastructures could be rejected by a minority of local groups or the

inhabitants in remote regions. The reasons against to build a renewable-energy power plant are mainly

caused by the misunderstanding or bias about the development of energy. Taiwan government, which is

conducted by the Ministry of Science and Technology (MOST), executed the National Energy Program

(NEP) to develop the green energy and to do an effective communication with the public about the

positive use of renewable resources in Taiwan. The "Public Communication of Green Energy and Low

Carbon Technology" is mainly used to publicize the fields in renewable energy and popular science

communication. The public will understand the importance of low-carbon emissions and green energy,

and then turns to support the national energy policy through an effective communication with the

professional and multiple opinions in all aspects of renewable energy.

In order to effectively reach the goals on the technology innovation and policy promotion of green energy

in Taiwan, and to create a friendly environment with low-carbon emissions and developing the relevant

green industries, this study will aim as follows:

A. Design visual communication materials to promote green energy: some of professional, lively, and

easy to understand new popular media materials such as infographics, info. for dummies, cartoons

and animation will be introduced in this study. It will help people to learn more about the popular

science of green energy and low-carbon knowledge with the necessity for development of green

energy and low-carbon technology in Taiwan.

B. Build a social media website for green energy and popular science about low-carbon technology: a

few official online communication tools such as MOST Facebook, Wow Knowledge, Wow Energy

NEP-II, will be introduced to the public. These two-way communication platforms can effectively

respond to current issues and helping people to learn more about green technology.

C. Public relations and propaganda on green energy and low-carbon policy: an effective and interactive

communication will be conducted to promote the green energy and low-carbon policy through some

face-to-face workshops or a live broadcasting. The highlights of NEP-II and its executive results will

be discussed and presented via different public relations platforms with current issues or depth

reporting articles reported on electronic and traditional media.

This study found the public may change their negative thought and attitudes to support the green energy if

they learned some clear and objective statements, infographics, cartoons or science films with pros and

cons about new energy. The development of national energy is a long-term program and green powers

must bring benefits to the society. Through the appropriate popular science media and knowledge sharing

materials to the public, especially for the elder inhabitants and kids in remote regions, the

misunderstanding and stubborn bias against to develop the green energy or renewable resources could be

decreased or dismissed in future Taiwan.

1. Background/ Objectives and Goals

Research activities conducted by clinical nurses are an important part of continuing education as quality

improvement through the practice of evidence based nursing (EBN) is expected. The barriers for the

clinical nurse to perform these studies include time constraints, insufficient knowledge of the current

literature, lack of authority to change practice, a deficit of critical appraisal skills, and inadequate support

for the implementation of research findings（Huchinson and Jhonston, 2004).Therefore, since 2007, the

Sapporo City University has supported nursing research. Previous studies noted that supporting a nurse

based on her level of research knowledge provided an intervention effect toward implementation of a

given program (Higashino, et al., 2016). While there are reports on the requirements for entire projects,

detailed specific needs have not been explored. The purpose of this research is to describe the specific

needs of nurses to pursue research and to clarify the future activities to support research.

2. Expected Results/ Conclusion/ Contribution

In total, 177 nurses completed the survey for analysis (response rate, 65.8%). The mean number of years

of work experience was 14.9 (standard deviation, 8.2). The mean number of research projects was 4.9

(standard deviation, 4.5), with 50.8% respondents being the staff nurses. The ethics review question had a

median score of 3 with intermediate difficulty. The data analysis question had a median score of 5 with a

high degree of support needed. Presentation had a median score of 3 with a moderate degree of support

required. Methods and data analysis both had median scores of 5, indicating that a high degree of support

was necessary. A total of 86.3% respondents received support in determining the methods of their studies.

There were very few responses to the questions about presentation and submission of the manuscript

because not many nurses could get that far in the process. The area with the least satisfaction about the

support received was literature review with only 83.1% satisfied; however, 98.1% were satisfied with the

support received regarding ethics review. About 94.3% respondents believed that assistance was needed

from the university with training to conduct follow-up, whereas only 79.0% believed that assistance with

motivation was necessary. Our results indicate that the following factors must be addressed to support

research by clinical nurses: teaching method, reviewing the literature, selecting an appropriate research

method, and analyzing the data. Our results also demonstrated that there was dissatisfaction with the

methods of communication used. To respond to the needs for research support from the university, it will

be necessary to consider clinical human resource development.

Rental Device’s Management by Using Barcode Application System

Yu-Hsuan Hsu, Yi-Cheng Hsieh

Changhua Christian Hospital

E-mail: yus77219@gmail.com

1. Purpose

The rapidly changing medical industry has dramatically changed the way hospital operate. In

collaboration with the medical device manufacturer, adopting short-term lease not only reduces hospital

cost, but also ensures the medical technology is updated in a timely manner; however, the management of

rental equipment cannot be ignored. At present, the barcode system is widely used in hospitals for

surgical instrument management. If the barcode system can be applied to the management of rental

equipment, it can further improve patient safety.

2. Situation

Traditionally, the operating room rental device registration flow sheet must be filled in by hand, including

the date of surgery, the surgeon, the operation time, the patient's name, the name of the brand, the name of

the device, then fill in the number of boxes and the estimated delivery time after contacting the

manufacturer. After the manufacturer delivers the device, the manufacturer must fill in the external

delivery device receipt, including the surgeon, patient name, medical record number, operation date,

brand name, and device name... then attach it to the device packaging. All checklists must be manually

filled in repeatedly, which is time consuming and difficult to keep track in the future.

3. Method

Operating room staff can use the surgical scheduling system to confirm the rental equipment’s brand and

name the day before. The relevant information is transmitted from the operating room to the Central

Sterilization Supply Department. In order to effectively identify and track the device, it is cleaned by the

Central Sterilization Supply Department upon its delivery by the the manufacturer and a sticker

containing patient’s name is printed and attached to the equipment.

4. Conclusion

The traditional handwritten checklist method not only increases the staff’s workload, but also raises the

issue regarding legibility of the writing and paper waste. Moreover, it is impossible to accurately track the

equipments use by the patient. The barcode system has been widely used in operating room equipment to

track and manage rental equipment and also transmit relevant information. In addition to printing a

barcode sticker containing only the patient’s name, the system can also be programmed to print a

complete message delivery slips. Therefore, the operating room staff can be more clearly assigned and

information delivered by the Barcode system is more complete.

1. Introduction

A central question in the domain of supply chain management and marketing is the manufacturer’s

distribution channel selection. Dell operates the direct channel in terms of either brick-and-mortar or

online store to sell PCs. The phenomena that manufacturers selling exclusively through independent

retailers widely expand across different product categories, e.g., Acer, Colgate, Gillette, Heinz, Kelloggs,

and Tylenol (Hsiao and Chen, 2014). Besides these, manufacturers have been competing with retailers at

the retailing layers for many years in different forms, e.g., company-owned franchises, catalog sales,

online stores, and factory outlets (Arya et al., 2007). Opening direct channels usually involves

manufacturers’ significant investments in destabilising the direct channel and adopting retail practice (Ha

et al., 2016). Whereas channel selection decisions on both the manufacturer’s (Cai, 2010; Khouja et al.,

2010; Hsiao and Chen, 2014) and the retailer’s sides (Wang et al., 2016) have been extensively

investigated and well understood, the impact of retailer’s selling advantage on channel selection with

specific features has been completely ignored and received no attention in existing literature. In

comparison with the manufacturers suffering from inexperience, inefficiency in retailing operations, or

the extra cost of opening e-commerce channel., traditional retailers usually have a selling advantage in the

sales and marketing process, which is stemmed from the fact that the retailer has superior knowledge of

customer preferences, more direct contact with customers, or economies of scope with other retailing

activities.

The primary purpose of this study is to bridge this gap by systematically comparing channel selection

decisions under the following four different supply chain structures proposed by Cai (2010) while taking

the retailer’s selling advantage into consideration to facilitate our analysis:

— a manufacturer-owned direct channel (Scenario D);

— a traditional single-manufacturer-single-retailer retail channel (Scenario R);

— a supply chain with two traditional retail channels (Scenario RR);

— a dual-channel supply chain with a traditional retail channel and a manufacturer-owned direct

channel (Scenario RD).

More specifically, we seek to address the following research questions:

(i) How would the retailer’s selling advantage affect the manufacturer’s channel selection decision?

(ii) How would the retailer’s selling advantage affect the retailer’s and consumers’ preferences

among different channel structures?

The main contributions of the present study are summarized as follows. First, the manufacturer’s optimal

decisions of channel selection are dual-channel, while the precious choice evolves around the

distributions of its selling cost. More specifically, the manufacturer chooses a mix of a traditional retail

channel and a direct channel when the selling cost is sufficiently small, and two traditional retail channels

when the selling cost exceeds a specific threshold. This approves the statement that retail competition is

typically viewed as a healthy economic driver (Arya et al., 2007). Second, we observe that the optimal

choices for the retailer are an exclusively retail channel or the configuration of a traditional retail channel

and a direct channel. Third, consumers favor the retail competition, that is, in the forms of two traditional

retail channels and the mix of a traditional retail channel and a direct channel.

The rest of this paper proceeds as follows. Section 2 describes the key elements of our model. Section 3

provides the basic results. Section 4 presents the central analysis. Section 5 concludes this study.

Abstract

Dental malocclusion is an distortion in dentofacial growth or an abnormal relationship between the teeth

and dental arches. Malocclusion could led to obstacles for the patient in terms of physical function, the

teeth which were not well arranged could be a good place to accumulation of residual food, so it could

caused caries and periodontal disease. Malocclusion can be affected with aesthetics, especially in class II

division 1 because of the convex of facial profie, resulting unattractive face and had an unfavorable

impact on a teenager’s psychological development. Adolescence is the time of crisis and seek an identity

with the case of malocclusion is more likely to be a victim of bullied in school so that could effected to

long- term psychosocial impact. This research was to investigate the influence of dental maloclussion

class II division 1 on the psychosocial impact among Junior High School Students in Makassar, Indonesia.

The study was conducting as an analytic observational with cross-sectional study design. Sample of this

research were 1st and 2

With the advent of the digital age, the application of information technology has become an inevitable

trend. Virtual reality (VR) incorporated into teaching, the development of new teaching models, the

cultivation of students’ self-directed learning, and the implementation of teachers’ use of interactive VR

teaching have also become new-generation teaching trends. Therefore, this study adopted E-learning

technology to enhance high school students’ mathematics learning motivation. With the “simultaneous

linear equations in 3 unknowns” unit as the example, this study presented the eight stereoscopic

corresponding models in three planes which are difficult to display in two-dimensional teaching, allowing

students to watch and operate in VR. This not only enhances students’ self-interaction in learning, but also

incorporates gamification to elicit students’ interest in math learning, thereby improving their motivation

to learn and at the same time reducing the burden and inconvenience brought upon teachers in material

preparation and related problems. The test process in this study includes a pretest, an experiment, and a

posttest. In the pretest questionnaire, Keller’s ARCS motivation model was adopted, with four dimensions

designed to gain an insight into students’ math learning motivation prior to the test. Then, the students’

were given a chance to operate a set of VR-aided learning materials which was setup in this study. The

VR-aided learning materials consisted of five units. In Unit 1 and Unit 2, the students in the VR

environment interacted with a flat screen showing a film. The content of the film was a 3-D model

extended from Escher’s illusion works. The 3-D model provided for students to observe served the

purpose of letting students understand the differences between 2D and 3D and how 3D models achieve

illusion through these differences. Unit 3 included eight dimensional models with three planes. Students

could deconstruct these models to understand how they were stereoscopically combined. Before starting

the next unit, the high school math teacher first conducted a 40-minute math class taught using the

conventional way. At the end of the class, the students were given Unit 4 and Unit 5. Unit 4 was a

question and answer game with eight dimensions in three planes. The questions were in three-dimensional

diagrams frequently seen in daily life. The purpose was to relate to students’ daily lives and facilitate

understanding and association. Unit 5 was a “simultaneous linear equations in 3 unknowns” question and

answer game. The purpose was to enable students to understand the association between “simultaneous

linear equations in 3 unknowns” and “graphs”. The design of these two units incorporated the

gamification element. First, the students were requested to answer all the questions within a given time;

otherwise, the train in the game would crash and end the unit. Then, after the end of both units, the leader

board of total scores for correct answers appeared to increase the fun of peer competitions. At the end of

the five units and conventional lecturing, the students filled out a learning motivation posttest

questionnaire. The questionnaire also adopted Keller’s ARCS motivation model to investigate the

students’ math learning motivation situation after completing the teaching material in the research design.

The Likert 5-point scale was used to analyze whether the students’ learning motivation increased The

overall test, including the pretest, the experiment, and the posttest took about 150 minutes to complete.

After the test, the study adopted the independent sample t-test to carry out an analysis and compare

differences in learning motivation before and after applying VR teaching aids in the course. The research

results show that although “the application of VR digital teaching material in high school math teaching”

and “enhancing the math learning motivation of high school students” showed no significant correlation,

the average score showed the students’ math learning motivation increased. Finally, based on observations

during the test conduction process and the class teachers’ interviews, it was inferred that the application of

VR digital teaching material in high school math teaching enhanced the students’ learning motivation. In

the future, the overall teaching aid design and usability will be optimized, thereby improving the overall

performance and specific recommendations that aid follow-up upgrade and revision will be proposed in

order to serve as references for schools, teachers, digital teaching aid development, and related studies.

1. Background/ Objectives and Goals

The purpose of this study was to examine the structural relationship among mother-child interactions,

father-child interactions, self-esteem and happiness of first grade children in Korea. In addition, we

attempted to examine the difference of variables between boys and girls.

2. Methods

Analysis of 1,361 households was conducted using t-test, correlation analysis and structural equation

modeling. Samples originated from eighth (2015) wave of the Panel Study on Korean Children (PSKC).

3. Expected Results/ Conclusion/ Contribution

The main results were as follows. First, it was found that boys showed higher level of happiness and

self-esteem than girls. The degree of mother-child interaction and father-child interaction were not

different between two groups. Second, child’s happiness was highly correlated with self-esteem,

mother-child interaction, and father-child interaction. Third, the results of structural equation modeling

analysis indicated that the mother-child had not only direct effects on children’s happiness, but also

indirect effects through the medium of children’s self-esteem. Father-child interaction had an indirect

effect on child’s happiness, mediated by child’s self-esteem. That is, child’s self-esteem had partial

mediating effect on the relationship between mother-child interaction and child’s happiness, and also had

a full mediating effect on the relationship between father-child interaction and child’s happiness. Fourth,

the results of multiple group analysis indicated that there was no difference in path weights between boys

and girls. These results indicate that mother-child interaction has a greater impact on the children’s

socioemotional development, but father-child interaction should not be ignored. The implications of these

findings were also discussed.

1. Background

In Taiwan, there have been many incidents of food safety that has caused the public to doubt and distrust

food production. People are becoming ever more conscious about food safety as its impact on consumers

isn’t merely on the psychological and physical level, but also encompasses risks to their lives; it can also

indirectly affect the understanding and reaction of consumers towards the risks of food safety. However,

Taiwan’s food traceability measures have been implemented for a long period, but food safety issues has

further emphasized the public’s attention to food traceability.

2. Methods

As CVM can evaluate unrealized market benefits, it’s suitable for this study in evaluating the public’s

willingness to pay to reduce health risks and their acceptance of a comprehensive food traceability system

(such as food traceability and graded certification labels).

3. Expected Results

The empirical results show that: (1) women are willingness to pay more cost for the food certificated label

attention. (2) The most important food marked name is listed below: certificated label, materials, calories.

(3) As a whole, almost average 30% respondents can absolutely understand the food traceability

information.
