This study identifies key determinants of participation in UCC services. Incorporating insights from the flow theory, we examine the effects of psychological factors of social presence, self expression, arousal, and challenge as well as web-site characteristics variables of media easiness, contents usability, and immediateness. We have done a sample survey of internet users and collected 260 responses. Using Windows SPSS/PC 12.0 Package, we have performed statistical analyses including a correlation analysis, a factor analysis, and a multiple regression analysis. The result of the study is as follows. Psychological variables of perceived social presence, self expression, arousal, and challenge all show positive significant effect on participation in UCC service. Among web site characteristics, media easiness, which consists of a web structure that is easy-to-use, user friendliness, and personalized service, demonstrates a positive significant effect on participation in UCC services. Immediateness also has a positive significant effect. Some of the practical implications of the result are follows. We should improve user access to platforms of UCC service by opening up platforms. This will heighten perceived challenge which has the strongest influence on participation in UCC services. We need to focus on multimedia services and adjust to the cultural code of netizen who crave for visual expressions and on the spot on-line activities. Also suggested is that contributions made by participants need to be acknowledged through such provisions as profit sharing. Needs for individualized service, which is an aspect of media easiness, should also be addressed. Participants tend to value individuality while at the same time accepting broader trends. Information services need to be customized for individuals. In UCC centered internet businesses, netizen consumers are presumer. They are consumers and producers at the same time, and consumer needs should also be explored for the success of internet businesses.

As knowledge is now being distributed and shared through the Internet not only in the form of text but also in that of video, UCC (User Created Content) knowledge video sharing services have emerged on the Internet such as Instructables.com. This paper deals with a UCC knowledge video service in real world and reports the case of analyzing its customer model. The knowledge video sharing service can be considered as both a kind of discontinuous innovation, which requires knowledge provider's technical ability of creating and editing UCC video, and a value network, which matches UCC providers and consumers therefore brings network effect, we first adopt the Chasm theory as the base of the customer model and refine the customer model referencing the Technographics, which is also an Internet-refinement of the Chasm model. Finally, non-customer analysis of Blue Ocean strategy is applied for exploring potential customers of the service.

최근 인터넷 공간에서 사용자가 직접 만들어 내는 컨텐츠, 즉 UCC (user created contents, 이하 UCC)에 대한 관심이 그 어느 때보다 증가하고 있다. UCC란 기존의 온라인 컨텐츠 제공업자와 달리 일반 사용자에 의해 만들어져 게시판과 같은 도구를 사용하여 온라인 상에 존재하였다. 그런데 UCC 가 최근 들어 더욱 관심을 받고 있는 이유에는 사용자들이 직접 컨텐츠를 만들어 개제하는 것이 용이하도록 변화된 환경의 조성 및 컨텐츠 제작을 쉽게 할 수 있는 저작도구가 지속적으로 만들어지고 확산되었기 때문이다. 결과적으로 사용자 측면에서는 다른 사람들과 소통하는 통로가 확대되었고, 사업자 측면에서는 보다 컨텐츠를 풍부하게 확보할 수 있는 환경이 열린 것이다. 본 연구는 구비문학의 이론을 통하여 UCC의 활성화에 영향을 미치는 요소를 탐색적으로 살펴보는 것을 목적으로 한다. 구비 문학은 텍스트를 향유하는 사람들 사이에서 공유되는 이야기로서 그 생산 환경의 매커니즘과 텍스트의 발전 양상이 UCC와 매우 유사하다. 따라서 본 연구에서는 자료의 분석과 이론적 모형의 수립 과정 전반에 있어 구비 문학의 이론과 접근 방법을 사용하였다. UCC가 매우 활발하게 생산되는 주제를 선정하여, 그 주제에 해당하는 커뮤니티의 특성, 사용자들 간의 관계, 사용자 정책 등 차이가 있는 세 온라인 커뮤니티를 선정하였다. 선정된 온라인 커뮤니티의 게시판의 포스트와 댓글을 프로그램을 통하여 수집하고 분석하였으며, 그 분석된 데이터를 바탕으로 사용자를 선정하여 심층 인터뷰를 진행하였다. 심층 인터뷰 데이터는 근거이론은 이용하여 분석하였다. 본 연구의 결과는 UCC 확산이라는 새로운 인터넷 패러다임 속에서 이를 구비 문학의 이론으로 분석했다는 점에서 학문적 의의가 있다. 또한 성격이 다른 세 개의 사이트에서의 UCC를 비교함으로써 UCC를 기반으로 한 사이트 설계의 가이드 라인이 될 수 있는 실용적 의의를 가진다.

Social network service is defined as an online service or communication service based on social relations among people applied the concept of social network. Social collaborative service included in social network service is characterized by the new value of modified content or recreated content made through collaborative creation process between members of the group. It has the remarkable merits such as sharing and collaboration. But, at the same time, it has the latent problems such as content reuse or copy that is not allowed for members to use. It has been emerged that UCC which is a typical example of recreated or modified content has the copyright issues in both creation and publishing step. To resolve this matter, we don't have many appropriate methods except CCL so far. So, in this paper, we define the problem and implement the UCC metadata manager to control metadata reflecting the feature of UCC. We draw the reference metadata element to identify original content utilized re-creation process. After that we define the R.Metadata Loader module based on the use case. Finally, the proposed UCC metadata manager provides the information of referenced content and lets us to identify the relationship between reference contents. So as to implement prototype, we use Kaltura which is CMS using open source and obtain functional extensibility of metadata manager by using open API.

최근에 웰빙 열풍에 의해 사람들이 기능성 음료, 건강 차, 마시는 물 등에 대한 관심도가 나날이 높아지고 있다. 그러나 사람들이 웰빙 열풍에 따라 건강에 좋은 물에 높은 관심을 갖고 있기는 하지만 실제로 자신들이 마시고 있는 물의 웰빙성에 대한 정보는 피상적인 수준에 머물고 있다. 왜냐하면, 물에 대한 기존 홍보 방법들이 단방향 형태의 단편 정보를 전달하는 수준에 그치고 있기 때문이다. 특히, 최근에 각광을 받고 있는 UCC를 활용하여 물의 브랜드를 제고시키는 연구는 아직 미미한 상태에 머물고 있으며, 상호작용성이나 체험성 형태를 제대로 갖추지 못하고 있다. 이에 본 논문에서는 제주 물에 대한 효과적인 브랜딩 방안으로 첨단 정보 기술과 제주 물의 특성을 융합하는 접근으로 체험형 UCC를 어떻게 제작할 것인지를 알아본다. 다양한 물 종류 중에서도 국내에서 우수한 물로 인정받고 있는 제주 물의 브랜드 제고를 위해 정보 기술과의 효과적인 융합에 초점을 맞추고자 한다. 제주 물은 지하수로 화산 암반수이기 때문에 제주를 다녀갔던 관광객을 비롯한 대부분 일반 사람들은 제주 물의 실체를 직접 보거나 체험해 볼 수 없다. 그러므로 단순히 제주 물을 홍보하는 UCC 형태를 탈피하여 상호작용적 체험을 통해 제주 물의 우수성과 브랜드를 보다 효율적으로 전달할 수 있는 방안을 제시한다. 또한, 3D 기술을 이용하여 입체적으로 제주의 물의 웰빙성을 느껴볼 수 있는 방안을 제시하고자 한다.

In this study, we investigated the characteristics of the conversion efficiency and the effect of ageing Diesel Oxidation Catalyst (DOC). The DOC was composed of Warm-up Catalytic Converter (WCC) and Underbody Catalytic Converter (UCC). As the result, the conversion efficiency of THC was 10$\~$50$\%$ on WCC and 30$\~$40$\%$ on UCC .The conversion efficiency of CO was 80$\~$90$\%$ on WCC and remained 10$\~$20$\%$ of CO was purified on UCC. The WCC shows high conversion efficiency on CO. After 20 hours aging process of engine bench, conversion efficiencies of THC and CO were improved a little, because it was activated catalyst surface by 20 hours aging. In case of 80 hours aging, the conversion efficiencies of THC and CO were decreased on WCC. However, the UCC was not affected by aging process .
