The Nine Core Technologies
Technology
The application of knowledge, skills, and resources to solve human problems and extend human capabilities. It is an applied scientific study of the human-made world. Technology can be broken into the following nine applied sciences or core technologies. These core technologies are the foundation of every technology system.
THE BUILDING BLOCKS OF TECHNOLOGY
Bio Technology
The technology of using, adapting, and altering organisms and biological processes for a desired outcome.
Applications of Bio Technology
Hybrids Genetic Engineering Cloning Controlled Environmental Agriculture Hydroponics Aquaculture Integrated Pest Management
Hybrids
A hybrid is the offspring of two plants (or animals) of different varieties, breeds, or species. The hybrid has characteristics of both its “parents”.
NAMING HYBRID BIG CATS
Only those hybrids which have been assigned names are listed. The usual convention is a "portmanteau word" comprising first part of male parent's name then second part of female parent's name (occasionally first part of male parent's name then first part of the female's name). Complex hybrids use the first part of the male parent's name followed by the original hybrid name.. The number of hypothetical hybrids is extensive.

Genetic Engineering
Genetic Engineering gives organisms traits they never had naturally. One way is by altering the organism’s normal genetic code. Another way is by moving one organism's DNA into another.
Cloning
The following three types of cloning technologies: (1) recombinant DNA technology or DNA cloning (2) reproductive cloning(3) therapeutic cloning
Cloning is the process of making a genetically identical organism through nonsexual means.

Controlled environment agriculture (CEA) integrates mechanization, computer-control and advanced sensors, intensive management of nutrition and pests, and any of a number of structures to develop highly productive, high-quality crops.
Hydroponics is often defined as "the cultivation of plants in water." Research has since determined that many different aggregates or media will support plant growth; therefore, the definition of hydroponics has been broadened to read "the cultivation of plants without soil."
Aquaculture is the rearing of fish, shellfish, or plants in water under controlled conditions.
Integrated Pest Management combines various techniques to control pest.
• Mechanical controls
• Cultural controls
• Biological controls
Applications of Bio Technology
• Prevention of Disease
• Diagnosis of Disease
• Treatment of Disease
• Prosthetics
Prevention refers to lowering the risk of disease.
This is largely because the most common diseases in developed nations today are chronic disease -- like heart disease and cancer. And chronic diseases tend to be caused by a combination of many different factors, some of which are under a person's control (like diet), some of which are out of person's control (like age), and some of which are still unknown. With so many factors driving risk -- only a portion of which can actually be changed -- the realistic goal of prevention becomes lowering the risk of disease, not eliminating it.
To identify a disease or illness by the signs and symptoms.
• Laboratory Tests
• Instrumental Screening
• Medical Imaging
• Surgical Examination
• Genetic Testing
Methods:
One goal of treatment is to cure disease, but when a disease is unknown or incurable, the goal is to relieve symptoms such as pain.
• Recombinant of DNA
Genetic material that has been altered and recombined in the laboratory by cutting up DNA molecules and splicing together specific DNA fragments. Many drugs, including the HBV vaccines, are produced using recombinant DNA methods
• Monoclonal Antibodies
Monoclonal antibodies are antibodies that are identical because they were produced by one type of immune cell, all clones of a single parent cell. Monoclonal antibodies are often used in diagnostic tests, such as ELISA.
• Gene TherapyGene therapy is a technique for correcting defective genes responsible for disease development.
Gene therapy is a technique for correcting defective genes responsible for disease development. Researchers may use one of several approaches for correcting faulty genes:
A normal gene may be inserted into a nonspecific location within the genome to replace a nonfunctional gene. This approach is most common.
An abnormal gene could be swapped for a normal gene through homologous recombination.
The abnormal gene could be repaired through selective reverse mutation, which returns the gene to its normal function.
The regulation (the degree to which a gene is turned on or off) of a particular gene could be altered.
• Tissue Engineering
Tissue engineering is the development and manipulation of laboratory-grown molecules, cells, tissues and organs to replace or support the function of defective or injured body parts.
• Surgical Treatments
New surgical tools and techniques have been developed. The provide more effective treatment, with less pain and faster recovery, than traditional surgery.
• Laser Surgery
• Cryosurgery
• Ultrasound
• Stomach Stapling
• Angioplasty
• Coronary Artery Bypass Surgery
That branch of medicine which deals with that artificial replacement of missing, diseased, or injured body pats.
