CCLINC SERVER Info Detection Summarization It seems that North Korea launch a missile again After North Korea launched a Daipodong missile last month, NK is perceived to proceed to an additional test launch. Korea, US and Japan enter into an alert state, and prepare for a joint response policy. Korea estimates that the additional launch will be on 09/05. Japan estimates that NKs missile range is short. US information says that there is no sign of launch yet. Translation What is the status of nk missile launch against japan? BugHanI IlBonE Ddo MiSaIlEul BalSaHan Deus HaDa 2-way Speech Transation

  • Slide 22
  • DLs: Why of Global Interest? F National projects can preserve antiquities and heritage: cultural, historical, linguistic, scholarly F Knowledge and information are essential to economic and technological growth, education F DL - a domain for international collaboration wherein all can contribute and benefit which leverages investment in networking which provides useful content on Internet & WWW which will tie nations and peoples together more strongly and through deeper understanding
