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.

This study proposed a research model that can explain the usage intentions of users and non-users by considering the performance aspects of personal mobility and external environmental factors based on the SOR (Stimulus-Organism-Response) model, A survey was conducted targeting domestic users and non-users, and research models and hypotheses were verified through Partial Least Square (PLS) and Artificial Neural Network (ANN). As a result of the analysis, it was confirmed that the users' perceived satisfaction and perceived trust had a positive effect on their intention to use, and that perceived risk and environmental value had a significant relationship with perceived satisfaction and perceived trust. For non-users, it was found that there was a positive correlation between perceived satisfaction and intention to use, and it was verified that perceived risk and environmental value, like users, were significant antecedents of perceived satisfaction and perceived trust. Among the remaining variables, the perceived mobility of users and the perceived ease of use of non-users were respectively presented as important influencing factors on perceived satisfaction.

Korea Communications Commission (KCC) has been providing the pilot service of URC(Ubiquitous Robot Companion), which is a network-based personal robot, to 1000 Korean households since 2006 to define potential users' needs and adoption behaviors. Personal innovativeness might play a critical role in adoption of URC services by users because much sophisticated and convergence technologies are incorporated into URC services. Also, defining not only perceived beliefs about URC services but also expected beliefs about them are very crucial to reduce disconfirmation between users' perception and expectation of URC services. From this point of view, this paper aimed to examine robot users' adoption behavior by considering constructs such as personal innovativeness, usefulness (perceived usefulness - expected usefulness, P-E), user attitude, and intention to use. The findings reveal that personal innovativeness is negatively related to usefulness (P-E) whereas usefulness (P-E) influences significantly and positively on user attitude. It is also shown that usefulness (P-E) and user attitude have strong positive effects on intention to use.

This study is to observe the correlation between user properties and user behavior on the mobile game, one of the most prominent digital contents with the most mutual interaction. Among various factors affecting on behaviors of game users, the user properties itself was accentuated, and the effect of individual and psychological quality on the use of game was evaluated. The user properties were mainly categorized into five factors of "interpersonal relationship", "level of game skill", "inclination of innovation", "self-esteem", and "competitive spirit", and the use behavior of game was categorized mainly into two types - quantitative behavior of "amount of use (time of use, consumption cost)" and qualitative behavior of "perceived satisfaction level (perceived enjoyment, perceived service quality, and perceived price)". As a result of study, in general, as the user quality subjected in this study is stronger, the amount of use and satisfaction level are higher. This study is to observe what type of user qualities leads to the more use, consumption, and satisfaction level of game contents to contribute to the study about the use of conventional digital contents and heavy use.
