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.

In addition, the structural relationships among cognitive trust, emotional trust, viewing commitment, and purchase intention were examined. Design/methodology/approach - For the empirical analysis of the study, a survey was conducted on 192 consumers who have recently experienced using personal media content. The Confirmatory Factor Analysis (CFA) and the Structure Equation Model (SEM) were hired in order to analyze the survey data. Findings - Findings of this study are 1) informativeness and expertise had a significant effect on cognitive and emotional trust. However, entertainment had no significant effect on both cognitive and emotional trust; 2) interactivity had a significant effect on emotional trust, but not on cognitive trust; 3) cognitive and emotional trust had a positive effect on the viewing commitment of the content; 4)content users' viewing commitment had a positive effect on their intention to purchase recommended products. Research implications or Originality - The theoretical and practical implications were discussed through the above empirical research results, and the limitations of the study and the direction of follow-up studies were presented.

본 연구는 특수교사들의 스마트미디어 수용에 영향을 미치는 요인들을 개인의 혁신성과 사회적 영향 두 가지 관점에서 설명하고자 구조방정식 모형을 통해 분석을 수행하였다. 요인들 간의 상관관계를 분석한 결과 개인의 혁신성, 사회적 영향, 성과에 대한 기대, 행위의도와의 상관관계가 있었으며 설정된 요인들 간의 경로분석을 통한 가설 검정 결과, 사회적 영향이 성과에 대한 기대에 영향을 미치는 직접효과 및 행위의도에 미치는 직접효과는 유의한 것으로 나타났다. 또한 사회적 영향은 성과에 대한 기대를 매개요인으로 하여 행위의도에 영향을 미치는 간접효과도 유의한 것으로 나타났다. 그러나 개인의 혁신성은 성과에 대한 기대나 행위의도에 직접적이거나 간접적으로 미치는 영향이 유의하지 않는 것으로 나타났다.

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.

On information markets, we can identify different relations between sellers and their customers, with some users paying with money, some paying with attention, and others paying with their personal data. For the description of these different market relations, this article introduces the notion of arity into the scientific discussion. On unary information markets, customers pay with their money; examples include commercial information suppliers. Binary information markets are characterized by one market side paying with attention (e.g., on the search engine Google) or with personal data (e.g., on most social media services) and the other market side (mainly advertisers) paying with money. Our example of a ternary market is a social media market with the additional market side of influencers. If customers buy on unary markets, they know what to pay (in terms of money). If they pay with attention or with their personal data, they do not know what they have to pay exactly in the end. On n-ary markets (n greater than 1), laws should regulate company's abuse of money and-which is new-abuse of data streams with the aid of competition (or anti-trust) laws, and by modified data protection laws, which are guided by fair use of end users' attention and data.
