This paper aims to consider the sexuality elements that the audience perceive from athletes on television images and how those elements influence on audience satisfaction. A total of groups were composed of 3 factors, and a group of men, 8 factors. As a result of the analysis, the correlation ratio to sexuality elements was relatively higher. But the correlation to the sexuality elements, the ratio of preference on sports and the audience quantity on sports program was hardly formed. Also, the result of analysis about the influence of these elements on the audience satisfaction of sports program showed that the higher ratio was in order of the audience quantity of sports program, the preference of sports, the sexuality elements, and so on. As a whole, it was shown that, for a group of college students, the athletes' sexual image on TV had only a slight influence on the audience satisfaction with sports program.

2006년 본 방송을 시작한 지상파 DMB 방송은 기존의 방송과 달리 하나의 물리 채널에 다양한 비디오와 오디오 서비스가 복합적이고 비 순차적인 형태로 제공되기 때문에 기존의 TV, Radio와 같은 기기 중심의 단순한 user interface 의 사용으로는 시청취에 제약이 발생한다. 따라서 비디오와 오디오, 오디오와 데이터, 비디오와 데이터와 같이 멀티 미디어 방송을 이동 중 시청취할 수 있는 새로운 형태의 user interface에 대한 개발이 필요하다. DMB 방송의 Information architecture 설계를 위한 기본적인 방송 관련 정보를 정의하였고, DMB 방송의 특징이라 할 수 있는 video service에 대한 고찰을 통해 DMB 방송 관련 기본 정보를 고찰하였다. 또한 방송 시청과 관련된 태스크 중심의 시나리오 개발을 통해 기능을 도출하고, 사용자들의 DMB 방송의 예상 시청 행태에 대한 조사 결과를 참조하여 필수적인 기능 중심으로 사용하기 쉽고, 기존 방송과 동일한 다양한 사용자를 고려하여 직관적인 인터페이스와 인터랙션을 제공하도록 설계하였다. 세부 UI 설계 단계에서는 기기 특성에 의한 제약 사항을 확인하고 방송구조의 시각화 대안 탐구 및 신호 해석에 의한 지연에 대한 민감도를 조사하고 방송 시청을 위한 화면 설계 및 네비게이션 방법을 설계하였다.

In this study, as the viewing characteristics of users of YouTube video content related to science education, 'Inflow and Access' is analyzed to find out the interaction between learners and the system, and 'Reaction and Subscription' to find out the interaction between learners and contents. To this end, the YouTube channel "Elementary Science TV," was selected as the subject of research. The channel is mainly focused on the contents of elementary science textbooks, STEAM, and gifted education. The channel's data of YouTube studio was analyzed. The following results were obtained through data analysis: first, as a result of 'Inflow and Access' analysis, YouTube video content related to science education was most often introduced through external links, and the access device was mainly a computer. Second, as a result of the analysis of 'Reaction and Subscription,' 'like' and commenting performed as a reaction to the video were less than 1% of the number of views. Most users watch without a subscription, and watch for longer when using self-directed. Although this study was analyzed through a limited channel called 'Elementary Science TV,' we were able to discover a little about the users' viewing characteristics of YouTube video contents related to science education. In the future, it is expected that it can be used as a basic material for creating videos related to science education for remote classes, establishing a science education video platform.

This paper empirically analyzes specific characteristics of VOD users and their practical viewing patterns, using socio-demographic data of the current IPTV subscribers in combination with actual data of genre usage and payment. The findings revealed active viewing patterns of male, the unemployed, high earners and early adopters. In terms of preferences, households with large numbers of women prefer time shift contents, whereas households composed of more men or preschoolers prefer non-time shift contents. Likewise, the households that have more women or higher income had relatively a lot of experiences of purchasing time shift contents on one hand, but the households characterized by the larger numbers of family members or unemployed householder or young householder showed much willingness to pay premium contents on the other hand. Given the utilization of correct database, the findings offer useful information conducive to service promotion and marketing strategies to maximize VOD use in the practical dimension.

The purpose was to examine the association between healthy weight and physical activity, screen time, and nutrition based on community characteristics in mountainous region. The sample consisted 1,620 middle school students in West Virginia, the United States. A logistic regression and in-depth interview were conducted. Moderate to Vigorous Physical Activity and consumption of vegetables and fruits were associated with healthy weight, while screen time was not associated with healthy weight. Regional limitations may cause that students had too much exposure to screen time and should be minimized by using school facilities during weekend. In particular, schools need to provide regular health seminars and parents education to overcome regional isolation and slow internet speed. Therefore, it suggests the cooperation between schools and parents may be required in order for students to be healthy in mountainous region.

A digital video is a very long data that requires large-capacity storage space. As such, prior to watching a long original video, video watchers want to watch a summarized version of the video. In the field of sports, in particular, highlights videos are frequently watched. In short, a highlights video allows a video watcher to determine whether the highlights video is well worth watching. This paper proposes a scheme for creating soccer video highlights using the structural features of captions in terms of time and space. Such structural features are used to extract caption frame intervals and caption keyframes. A highlights video is created through resetting shots for caption keyframes, by means of logical indexing, and through the use of the rule for creating highlights. Finally, highlights videos and video segments can be searched and browsed in a way that allows the video watcher to select his/her desired items from the browser.
