디지털 카메라와 캠코더의 보급이 증가함에 따라 일반 사용자들의 UCC(User Created Contents) 역시 일반화 되고 있다. 그러나 이에 따른 사생활 침해 또한 증가하고 있다. UCC는 인터넷 포탈 서비스를 통해 공유될 뿐 아니라 DVD(Digital Versatile/Video Disk)와 같은 저장매체(Recordable Media, 이하 Media)를 이용하여 보관된다. 포탈 서비스를 이용해서 콘텐츠를 게시하는 경우 포탈 시스템이 제공하는 사용자 인증 및 불법 다운로드 제어 기술을 이용하여 사생활 침해를 부분적으로 막을 수 있다. Media의 경우도 불법복제 제어기술을 채택하고 있지만, Media의 도난 또는 분실로 인한 콘텐츠 유출과 사생활 침해를 막을 수 있는 방법이 현재로서는 제공되지 않고 있다. 그러므로 Media를 이용하여 개인 콘텐츠를 관리하는 경우에도 사생활 침해를 막을 수 있는 추가적인 보안 기술의 연구가 필요하다. 본 논문에서는 Media 보안을 위해 제정된 AACS(Advanced Access Content System)의 Framework을 살펴보고 개인 콘텐츠의 접근을 제어할 수 있는 개선된 AACS 보안 Framework을 제안한다.

Nowadays personal users create a variety of multi-media contents and share them with others through various devices over the Internet since the concept of user created content (UCC) has been widely accepted as a new paradigm in today's multi-media market, which has broken the boundary of contents providers and consumers. This paradigm shift has also introduced a new business model that makes it possible for them to create their own multi-media contents for commercial purpose. This paper proposes a tangible virtual studio using augmented reality to author multi-media contents easily and intuitively for personal broadcasting and personal content generation. It provides a set of tangible interfaces and devices such as visual markers, cameras, movable and rotatable arms carrying cameras, and miniaturized set. They can offer an easy-to-use interface in an immersive environment and an easy switching mechanism between tangible environment and virtual environment. This paper also discusses how to remove inconsistency between real objects and virtual objects during the AR-enabled visualization with a context-adaptable tracking method. The context-adaptable tracking method not only adjusts the locations of invisible markers by interpolating the locations of existing reference markers, but also removes a jumping effect of movable virtual objects when their references are changed from one marker to another.

Telecommunications-broadcasting convergence in the domain of IT is a representative phenomenon that is expected to provide the saturated existing markets with a new source of profit. Especially, T-Commerce combines familiarity of TV and immediacy of the Internet which are expected to cover all the users familiar with each media and expand the existing commercial transactions. Telecommunications-broadcasting convergence in Korea, however, is focusing on technical and regulatory aspects so that research on the real users is not up to the mark yet. This is the most fundamental problem in hampering growth in the corresponding service and market. Thus, we are proposing an adoption model on T-Commerce to rapidly expand the convergence service through understanding the potential users. Perceived utilitarian and hedonic values, perceived interactivity, media substitution and personal innovativeness have been examined as the factors influencing the users' intention to adopt a new convergence service. As a result of empirical analysis, it is verified that perceived utilitarian and hedonic values and personal innovativeness directly influenced the users' intention to adopt whereas perceived interactivity had indirect affect on them. T-Commerce service providers should not only emphasize on the benefit that the older media could not provide the users with, but also provide them with more pleasure and entertaining experience during the course of satisfying the users' needs to distinguish T-Commerce from the other existing media.

The purpose of this study was to investigate the effects of mass media and personal factors on attitudes towards plastic surgery and plastic surgery behavior. For this study the personal factors included concern for appearance, self-esteem, and body satisfaction. Subjects were 472 college students in Ulsan. The results showed that favorable attitudes towards plastic surgery were a little higher than the median, meaning that the respondents had a slightly positive attitude towards plastic surgery, and only 20% of the respondents had had an experience with plastic surgery. A multiple regression analysis was computed and indicated that a more positive attitudes towards plastic surgery was related to high levels of concern for appearance, more time watching TV, a higher household income, and being a female student, in terms of gender. The results of logit analysis indicated that a more positive attitude towards plastic surgery and being a female student related to a higher probability of having had plastic surgery.
