Whereas traditional user interface are well accepted modes of information exchange, the new digital conversion type's of information media is relatively complex and provides new means of transaction with user interface. User interface can be decomposed into two component: the physical structure through which information media is controlled, and the presentation of the content. This research explores the two user interface element have different effect on the adoption of information media and, as such, can influence perceived usefulness, perceived easy of use, and intention of use. The hypotheses have been tested with the survey of 148 end-users examines two interface characteristics factors such as efficiency, error, design, entertainment, accuracy, and vividness, and so on. The research summarized in this paper decomposes the influence of interface elements of physical structure interface and content presentation interface to gain a better understanding of how interface stimulates user's perceived usefulness to adopt the information media.

The development and accomplishment of Open Source Software(OSS) is one of the hottest, as well as the most recent topics in the software industry. Prior studies with respects to OSS have concentrated on discovering both developers and users' rationales of participating OSS projects, analyzing specific OSS solutions or OSS movement itself. However, the empirical study on identifying determinants that influence organizational adoption of OSS and further diffusion of the technology has been a scant. Thus, the main purpose of this study is to investigate the key determinants affecting organizational adoption of OSS. The proposed research model incorporates organizational needs(Evolutional Leadership, Adaptive performance, Readiness for Change) and technological needs(Job Relevance, Cost Benefits, Software Quality) in order to explain organizational OSS adoption. Further, this study assesses the impact organizational OSS adoption has on the OSS Performance and OSS Diffusion. Results from 366 adopting organizations in various industries show three constructs in organizational needs and two constructs in technological needs with exception of Job Relevance have a significant influence on OSS Adoption; and adoption impacts its performance, and diffusion. The implications of the results suggest not only a new theoretical model for OSS research, but also the important implications for OSS diffusion.

Grounded in the prior literatures on acceptance and diffusion of IT and innovation in the level of organization research, 3 major constructional factors such as Motivation, IT resistance, and IT change management were investigated to suggest propositions from 15 multi-cases of PLM from 6 different companies in Automotive OEMs and suppliers, and we posited that the diffusion is continued only when motivation is stronger enough to overcome IT resistance as a fundamental finding and basis of this research on PLM acceptance and diffusion. The Motivation was found to be initiated and categorized from three different factors such as environmental factors, organizational factors, and technological factors, providing key propositions for further research: (1)The Automotive suppliers, contrary to OEM, are affected more by the demand of inter-connectivity as an environmental factor, while the other factors are similarly influencing to them, (2)The big organizations are influenced more by the champion, while the small organizations get influenced more by leader. (3)When the trend, inter-connectivity and complexity get stronger, the motivation gets more strongly influenced by the perceived benefit in the technological context. Regarding Change management we suggests IT change management is supportive to overcome IT resistance and also to enforce Motivation, and the critical mass exists differently according to the market maturity adopted, and more market matured technology has lower critical mass, implies less requirement of IT change management than less market matured technology.

In the knowledge-based society, ICT should take an integral part in K-12 curriculum. The purpose of this paper was to investigate the means to integrate ICT into K-12 curriculum. For the purpose, we reviewed the current national curriculum in light of ICT use. From the review, we identified that the recently revised 7th national curriculum reflected the necessity of using ICT in the view point of knowledge-based society, but it did not include the ICT specifically as a critical element of the curriculum. We discussed the meaning of ICT integrated curriculum, and also the role of ICT as a component of the curriculum. Finally, we suggested the direction of restructuring the curriculum as we consider integrating ICT into it.
