By conceptualizing UCC users' active behavior, this study newly presents two key concepts, 'self-expression' and 'artistic activity' of UCC users. Then, this study suggests a research framework to analyze text, image, and video UCC adoption processes by integrating those concepts with already-built UCC research tradition. Using the framework, we found that individuals who has a hard time expressing themselves in reality are likely to have a favorable attitude toward UCC, and the stronger the faith about the justice of self-expression and its freedom, the more the favorable attitude toward UCC. Furthermore, we confirmed that individuals who are very interested in artistic activity, and individuals who has high self-efficacy to their artistic talent are likely to participates more in UCC production. The role of other factors such as perceived enjoyment, the perception of critical mass of UCC adoption, and subjective norm also were discussed with limitations of this study.

UCC, an abbreviation for User Created Contents, is not only a symbol of desire but also a product of creativity that a producer contains his or her subjective disposition. More and more UCC tend to have significantly increased in Web 2.0 environment. However, the research on the contents as a creative product has rarely been processed. It may be fairly said that this results in the indifference of researchers in the special field like the political contents since UCC is usually produced by amateurs. Producers' various desire is unlikely revealed, which leads to the flow of users into open media such as the Internet. It could also be available to represent the property, of plural visual language signs in a field. Moreover, UCC has the attribute of re-mediation in effective communication, so the differences between the semiotic properties in the Internet contents could be a significant material for researches. This could contribute to establish a theoretical system for the visual communication. Therefore, this study aims to analyse the signification of the political video UCC, . To develop this analysis, I apply Greimas' Generative Trajectory of Signification Theory to the text, or the UCC. He classifies it as three structures: deep structure, superficial structure, and discourse structure. As a result, the text shows meaningful contents delivering core political messages. In addition, this approach could exam that 'Obama Syndrome' in American recent presidential campaigns is caused by web 2.0 based on Internet campaigns including video UCC.

The web 2.0 is leading a rapid change of internet services. The UCC(User Created Contents) service is one of the representative internet services with web 2.0 paradigm. In this paper, we design and implement the UCC services prototype system for image and video. The proposed system does not need to install ActiveX and client programs on devices of users to edit their contents. All processes for editing UCC are conducted on the server. Our proposed system consists of the two components such as the multimedia editing subsystem and the metadata management system. They provide the API to UCC service developers or vendors. The multimedia editing subsystem supports editing for image and video, and the streaming services of video. The metadata management subsystem supports the metadata management and retrieval of image and video.

This study explored three questions: (1) what are the motives of producing and using user-created contents (UCC, video clips which are produced and uploaded at various web sites by individuals), (2) what are the gratifications that users obtain from UCC, and (3) what are the differences of gratifications according to individual uses of UCC. A survey was conducted to 258 UCC users and data were factor-analyzed to find the dimensions of motives and gratifications. As for the motives of UCC uses, six factors were constructed: self-expression, private life, participation, information retrieval, rest, and entertainment, among which self-expression showed the largest variation. As for the gratifications, five factors were constructed: self-expression, rest, information retrieval, socializing, and entertainment.

We propose a novel non-photorealistic rendering technique which generates a cutout animation from a video for UCC. Our method consists of four parts. First, we construct an interactive system to build an articulated character. Second, we extract motions from an input video. Third, we transform motions of a character in order to reflect characteristics of cutout animations. Fourth, we render the extracted or transformed components in cutout animation style. We developed a unified system for a user to easily create a cutout animation from an input video and showed the system generated a cutout animation efficiently.

The Information and Communication Technology(ICT) is applied variously by advanced development, however that also causes the ethical problem simultaneously nowadays. It is emphasized the necessity of information and communication ethics and the scheme also is suggested that the student actually may produce and use their own UCC as an educational material which relates to ethics of information and communication in this paper. By doing that activity, student could learn themselves from what they've produced. Therefore they can approach the subject with more interests, beside the method how teacher has been teaching normally which can be described as cramming. The suggestion is phased by the steps as below; First of all, adequate guidance is selected and the aim of education is established to the method of education through producing UCC by analyzing the contents system of information and communication ethics. Second, it is analyzed educational effect along media of UCC. Third, it is analyzed educational effect along the producing format of UCC. Finally, the scheme is developed that student could be learned from UCC they have created. Therefore, students could be participated by themselves more actively to the education and manage the negative effects of ICT. They also could acknowledge and determine the right ethical awareness of information and communication, and develop more advanced ethical awareness by doing this activity.

Due to advance of communication environment and storage media, economics at home and abroad gets changed to active consumption environment to make digital contents by oneself and to consume ones. Specially UCC to be made by a user has been generating the various effects enough to be a issue in all the world. UCC multimedia among UCC quickly emerges as a core of crustal movement of Internet and so does an enterprise to concentrate his efforts on UCC multimedia. In this paper, we analyze the technical trend for UCC multimedia service and review the base techniques. Throught these studies, we bring up the growing direction for development of UCC service at the future.

최근 정보의 형태는 텍스트나 이미지 기반에서 벗어나 복합 멀티미디어, 즉 동영상 위주로 빠르게 이동하고 있다. 특히 사용자에 의해 제작되고 유통되는 동영상 UCC의 급격한 부상은 사용자의 정보 생산력과 정보 공유, 소비 형태를 능동적으로 변화시키고 있다. PC 뿐 아니라 IPTV에서도 주요 서비스 모델로 관심을 받는 동영상 UCC는 향후 지식 결부형 학습 콘텐츠로 옮아갈 것이라 예상되고 있으며 여기에는 수익 모델의 개발과 저작권 보호 이슈가 해결해야 할 선결 과제로 인식된다. 이에 본 논문은 방송 콘텐츠 제공 표준 기술인 TV-Anytime, 학습객체메타데이터인 LOM(Learning Object Metadata)을 기반으로 OSMU 동영상 UCC 학습 콘텐츠 서비스 모델을 위한 에디터를 설계하고 외부 콘텐츠 소스를 활용할 수 있는 콘텐츠 저작 시나리오에 기반한 메타데이터를 설계하였다. 이를 통해 사용자의 다양한 지식을 활용할 수 있는 UCC 학습 콘텐츠 서비스 모델 발굴과 콘텐츠의 확대 재생산에 있어서 적극적인 저작권 보호가 이루어질 것을 기대한다.

In recently, as the interest of media contents increase among internet users, a variety of media contents are circulated in the web. Especially, video-media content in media contents attracts internet user's interest. In conjunction with web 2.0, internet users open and share their making contents by themselves. Their attitude about accepting media contents is not passive but aggressive. Additionally, they create new form of distribution of the flow. Video media content for distribution on the Web is created by experts to a professional content, but Web 2.0 era, the UCC (User Create Contents) in the form of self-produced content is the most. The generated media by the general internet users, but self-produced content, provides video information only and has limitations. To satisfy internet users as consumers in the web 2.0 eras, it has needed to provide actual feeling contents that add various effects not just simple media. Therefore, this paper represents the existing media content with simple information based on the concept of ontology and the meaning to the subject for the media content. We will provide an actual feeling how to offer the configuration of a service model (AF-VS : Actual Feeling Video Service).
