Satellite television receiving antenna is required for watching TV on the vehicles, ship and car. Recently TV is not only facility as getting information but one of utility in our life. In Korea, already on the service multi-channel satellite TV using excellent visibility and sound, and there are many users using now by fixing antenna. On this thesis, developed ship's satellite TV receiving antenna, the azimuth controlling is adopted azimuth information using gyro sensor and differential of receiving signal strength algorithm, and elevation controlling used gimbals. The result of this research is successfully implemented Korean satellite tracking antenna as performance until ${\pm}$30 degree roll and pitch of ship motion.

Smart TV is a television set with internet capabilities, computing ability, and broadcasting service that increases user interactions. Usability has been regarded as one of the most important criteria for measuring and evaluating smart TV. To evaluate smart TV from the perspective of usability, we first need to develop a measurement model by determining the major factors affecting usability, which become a measurement the evaluation criteria of the model. The objective of this paper is to suggest an AHP(Analytic Hierarchy Process) model for measuring usability of smart TV. Factors affecting usability are described from the prior research. We show how the judgment data is acquired and the usability score is computed by an numerical example.

FPD(Flat Panel Display) 시장은 디지털 기술의 발전으로 급속하게 성장하고 있으며, 이는 TV 시장에서도 마찬가지이다. 많은 전문가들은 LCD(Liquid Crystal Display)와 PDP(Plasma Display Panel)의 기술적 차이로 인해 LCD는 소형 크기의 TV에 적합하고, PDP는 대형 TV에 적합할 것이라 예상하고, 이에 따라 FPD TV 시장에 적용되는 기술이 목표시장(target market)에 따라 양분할 것으로 전망하였다. 그러나 LCD 생산기술상의 예상치 못한 급속한 진전은 PDP가 목표로 하는 대화면 TV 시장에서 LCD가 독자적인 틈새시장을 형성하고 이를 점차 확대할 수 있도록 하였다. 이러한 시장 전개 양상은 LCD와 PDP의 경쟁을 심화시키고, 현재 앞에서 전망한 바와 같은 현상은 발견되지 않고 있으며, 오히려 대화면 TV 시장에서조차 LCD가 우위에 있음을 보여주는 사례가 많다. 본 연구에서는 LCD가 PDP와의 기술적 격차를 줄이고, 결과적으로 LCD와 PDP간 경계를 무너뜨린 보다 근원적인 원인을 분석한다. 특히 이러한 잠재적 메커니즘을 시스템 다이나믹스 방법론을 도입하여 분석한다. 특히 PDP에 대하여 점진적으로 LCD가 우위를 확보하게 되는 피드백 루프들을 밝혀 내고자 한다. 그리고 이러한 피드백 루프 중에서 가장 효과가 큰 메커니즘을 찾아낸다.

The questionnaire survey was carried out to analyze the difference of consumers perception on apparel products presented in catalog, cable TV home shopping program, and internet shopping site. 676 men and 728 women participated in this survey and they were members of catalog shopping or cable TV home shopping companies or netizen. The results of this study show that the shoppers perception on apparel home shopping differed by the direct shopping media that they frequently utilize and by their demographic characteristics. The cable TV home shoppers had higher reliability on product quality than the shoppers using paper catalog or the internet shoppers. The cable TV home shopping members perceived that the apparel products available in cable TV home shopping were diverse and the information about the products was sufficient to decide purchase. The married women tend to think that the TV home shopping program provides diverse apparel products in the aspects of color, design, size and the information about the materials including fabric.

TV는 타 도메인과 달리, 사전에 정해진 시간에 콘텐츠가 방영된다. 그러므로 TV 프로그램 추천 시스템은 시청자의 현재 시각(time-context)을 고려해야 한다. 시간 기반의 TV 프로그램 추천 방법이 다수 연구되었지만, 대부분의 기존 연구는 특정 시간대(timeslot)에서의 시청자의 선호도를 계산하는 데에만 집중되어 있고, 시청 내역 전체기간에서의 선호도를 고려하지 않은 문제점이 있다. 이러한 문제를 해결하기 위해, 시청자의 지역 선호도와 전역 선호도를 모두 고려한 시간 기반의 TV 프로그램 추천기법을 제안한다. 이를 위해 제안 방법에서는 시간대의 길이에 따라 여러 가지 선호도 모델을 사용한다. 여러 개의 선호도 모델로부터 산출된 선호도를 병합하여 가장 선호도가 높은 TV 프로그램을 추천한다. 실 데이터를 이용한 실험을 통해 기준방식과 비교함으로써, 제안 방법의 효용성을 검증하였다.
