IPTV has been drawing attention as a representative convergence media. The analysis of the convergence media, as like IPTV, requires an investigation into the use perception and multidimensional factors. So this research examines the IPTV usage, based on the Technology Acceptance Model. The analysis was made with the 500 users, based on the online survey. The first results is concerned with the user characteristics. A positive influential relationship between the user characteristics and use perception was confirmed, along with the individual attribute and environmental influence. The second, 'perceived ease of use' was found to positively influence 'perceived usefulness' and 'perceived playfulness'. This finding suggests that it is an important diffusion strategy to enhance the ease of use of IPTV. The third is the emphasis of playfulness of IPTV. Since IPTV is multimedia, playfulness played a significant role in diffusing IPTV. The application of the TAM to the media analysis of IPTV, which reflects the environments of the convergence media and use perception, was successful in drawing a significant outcome.

The present research aimed at investigating the impacts of volunteer activities on self-development and sociability-development. In study 1, the scale comprised of 15 items was developed to measure the meaningfulness of volunteer activities. An exploratory factor analysis was conducted on the data obtained from 428 undergraduates (193 males and 235 females). A confirmatory factor analysis was then conducted on the data obtained from 280 undergraduates (124 males and 156 females). In study 2, the impacts of volunteer activities on 947 undergraduates (461 males and 486 females) were analyzed in terms of self-development and sociability-development. Self-development consisted of self-evaluation, self-esteem, and quality of life. Sociability-development consisted of pother-acceptances, sense of community, and democratic citizenship. The results showed that not more volunteer activities itself but more meaningfulness of those activities had stronger relations with self-development and sociability-development. Finally, a values of the undergraduates internalized for volunteer activities and their levels of self-development and sociability-development expectation were discussed.

This study is aimed at understanding the factors behind deciding to accept a social network service (SNS) from the viewpoint of tourists who are users of tourism SNS. The study also seeks to clarify the effects these deduced factors have on the intention of users to continuously use SNS. To this end, individual properties (such as self-efficacy, socio-cultural effects, social presence and people's innovativeness), systematic properties (like system quality and information quality)and usefulness/availability were used as factors with regard to the decision to accept tourism SNS based on previous studies and efforts were made to structurally clarify the effects of such previous factors on people's intention to continuously use SNS through perceived value and satisfaction. SNS had significant effects on satisfaction and, furthermore, significantly affected tourists' intention to continuously use it. Based on such study results, factors behind deciding to accept SNS from the viewpoint of tourists affected customers' perceived value and satisfaction and ultimately affected their intention to continuously use SNS. To achieve the purpose of the study, a survey was conducted on about 250 Busan residents who had used SNS in relation to tourist activities, such as exhibitions, conventions, accommodation, trips, aviation service and transportation. According to an empirical study, factors behind deciding to accept tourism SNS, including individual properties, systematic properties and usefulness/availability had statistically significant effects on perceived value. The usefulness/availability factor had the largest influence, in particular, followed by the systematic factor and individual factor. The value perceived in the process of using tourism SNS had significant effects on satisfaction and, furthermore, significantly affected tourists' intention to continuously use it. Based on such study results, factors behind deciding to accept SNS from the viewpoint of tourists affected customers' perceived value and satisfaction and ultimately affected their intention to continuously use SNS.

This study attempts to analyze the effects of public advertising about suicide prevention and to investigate how the attitudes and perceptions of the message recipients differ according to the message framing type (positive vs. negative) and the appeal type (self-oriented/other-oriented). Positive messages, rather than negative messages, have a greater impact on people's respect for life and on attitudes to suicide. Respect for life attitudes were more positive among subjects who received an other-oriented message than among those who received a self-oriented message. Among the individual characteristics variables, the level of cognitive emotion regulation showed a significant impact on attitudes to respect for life and on attitudes to suicide.

식육의 독특한 맛 성분과 향기성분의 전구물질은 각각 적육과 지방 조직의 수용성 물질이라고 보고되어 있으며(도변(渡邊) 과 좌등(佐藤), 1974), 가열육의 기호성에 관여하는 향미는 복합적인 전구물질들이 열처리 과정에서 일어나는 여러 가지 반응에 의하여 많은 휘발성 물질들이 생성되면서 얻어지는 것으로 알려져 있다. 식육향에 관여하는 휘발성 성분들은 약 600개 이상이 동정되어 있고, 식육의 종류, 품종, 연령, 성별, 사료 등이 이러한 향기에 영향을 주며, 또한 도살 후 저장되는 동안에 휘발성 성분들의 변화 양상은 가열육의 향기에 절대적인 영향을 주게 된다. 일반적으로 냉장육의 경우는 자기 소화에 의한 숙성 효과로 연도와 풍미가 향상되게 되며 숙성된 육은 비숙성육보다 기호성이 우수하다. 우육의 기호성은 향기, 맛 및 조직감이 상호작용하여 결정되는데 우육에 함유되어 있는 지질 및 지방산 조성은 우육의 맛과 풍미에 많은 영향을 미친다(Waldam 등, 1968). 도변(渡邊) 과 좌등(佐藤)(1974)은 지질이나 유리지방산 등에서 생성되는 화합물들과 지방산의 불포화도, 지방산의 자동 산화 정도 등이 우육 향기에 관여하고 있다고 하였다. 본 연구 결과는 저장온도가 낮을수록 저장성을 증가시킬 수 있다는 김 등(1996)의 보고와 일치하였다.
