KBS는 세계 최초로 지상파 4K UHDTV(Ultra-High Definition Television) 실험방송을 9일 시작하였다. UHDTV 방송기술은 차세대 방송기술로 주목받으면서 선진국들간 주도권 경쟁이 치열하다. KBS에서는 지상파 4사 UHDTV 추진 협약에 따라서 KBS관악산UHDTV실험국 준공을 완료하고 현재 4K-UHDTV 신호를 송출하고 있으며, KBS연구동 기술연구소에 수신점을 마련하고 24시간 수신 중에 있다. 본 논문에서는 실험방송 송수신 전송시스템 개요에 대해서 알아본 후, 4K-UHDTV가 요구하는 최소 비트율 30Mbps을 만족하기 위한 최소 ToV(Threshold of Visibility) 값과 그 때의 전송 파라미터 구성에 대해서 살펴본다.

With the increasing concern about natural resources that is being devastated and lost its reproductivity, Non-use value of resources for future use is considered more important than the present use value in the resource valuation. This study aims to measure Total Non-use value in Namsan Park, Kwanak and Paldal Mountain with CVM(Contingent Valuation Method). CVM is the method which can evaluate Non-use value of tourism resource to find the future value of the given resource. This study is carried on the assumption that respondents give answers not to real situation but to imaginary circumstances. After analysing benefit value by estimating conservation value and separate use value, we can conclude that conservation value of tourism resource is given much weight.

As school libraries increase quantitatively, the importance of volunteer activities in school library is highly emphasized. In that regard, this thesis approaches and discusses the concept of the school library and school library volunteers systematically through the literature review. Surveys and interviews were conducted to investigate and analyze school library volunteers. The survey was completed by school librarians and school library volunteers separately from the 12 elementary schools in the Seoul Dongjak District Office of Education. The current situation of school library volunteers has been analyzed through surveys and accompanied interviews and, based on the analysis, some suggestions were made to improve school library voluntary activities.
