The purpose of this paper is to propose the frequency allocation plan for the terrestrial UHDTV in 700MHz frequency band. Currently 700MHz frequency band is being requested by broadcasting, communication, and public safety sites for the use of UHDTV, LTE/LTE-A and PPDR (Public Protection and Disaster Relief) by each site. Validity and proper timing of each request is examined by references, and the frequency allocation plan is proposed. As results 9 channels and guard bands are allocated for the UHDTV service, under the consideration of two 10MHz frequency bands of the PPDR in700MHz band.

방송 인프라도 드디어 ENG VCR시대를 넘어 컴퓨터시대로 점차 마이그레이션 하고 있다. 이같은 IT기반의 환경은 워크플로우 개선을 통한 회사 경쟁력 향상를 도모함과 아울러 조직의 리엔지니어링을 가속화하여 조직의 최적화(Optimization)를 구현한다. 예를 들면 워크플로우 개선 측면으로는 콘텐츠 입력$\cdot$검색$\cdot$모니터(Acquisition ＆ Searching ＆ Browsing), 자료의 복사$\cdot$편집(Copying ＆ Editing), 프로그램의 배달$\cdot$송출$\cdot$출력(Delivery ＆ Transmission ＆ Retrieval)등이 새롭게 나타나거나 변하여 시간비용을 대폭 절감하고, 업무의 정형화 및 리소스 공유로 효율적 비용관리와 분배구조를 구축하며, 작업과 승인 프로세스의 원활화로 생산성이 크게 향상된다. 또한 하루 24시간, 1년 365일 상시 운용이 가능하며, 테이프 구입비, 시스템 보수.유지비(TCO)등 각종 비용이 크게 절감된다. 디지털 아카이브 구축으로 콘텐츠 재활용의 극대화, 콘텐츠의 효율적인 관리, 효율적 콘텐츠 가공, 다양한 메체로 전환가능, 지적 재산권의 확보가 가능하다. 이밖에 원소스 멀티유즈 환경 구축을 통해 다양한 수의 창출 채널이 확보되고, 새로운 상품 개발이 가능하며, 고객의 니즈에 더욱 충실해 질 수 있다. 이같이 방송 인프라의 펀더멘탈 변화에 의해 방송제작$\cdot$편집$\cdot$송출에 관련된 환경이 크게 바뀐다.

A method for improving prediction accuracy through processing time series data has been studied in this research. We have designed techniques to model multiple similar time series data and avoided the shortcomings of single prediction model. We predicted the future changes by effective rules derived from these models. The methods for testing prediction accuracy consists of three types: fixed interval, sliding, and cumulative method. Among the three, cumulative method produced the highest accuracy.

At this point in time, advertisements data providers have no standard way of organizing advertisements, which has been causing confusion in information-sharing and data research. The purpose of this study is to design of metadata element for TV commercials by analyzing the characteristic features of TV commercials. First, it is to analyze characteristics, production process, composing elements of TV commercials through the literature review. Second, it is to analyze the characteristics of metadata elements on TV-Anytime and PB Core. Third, the 7 cases of advertisements data service providers are analyzed to extract the relevant data elements for TV commercial metadata. Forth, a Dublin Core was selected as basic metadata schema for TV commercial. Basic element is set as nineteen elements including , , , and . Sub-element is set as twenty seven elements. Finally, it is hoped that further studies of greater depth and specificity on organization and management of advertisements data may be undertaken.

If teachers should showed geomorphological landscape images familiar to students during geomorphology unit teaching in secondary geography education, it will have more effects on teaching. In this paper, we analyze whether teaching of geomorphology unit using media(movie, drama, entertainment program) background images familiar to students have an effect on understanding of teaching facts and interesting or not. Firstly, teaching using media data is effective in understanding of teaching facts and the results of examination taken after teaching improved. Secondly, teaching using media data is effective in interesting and understanding on geomorphological landscapes. Most students recognized this teaching method to be new and became to be interested in learning geomorphology unit, and answered that it was helpful to understand geomorphology unit.
