The purpose of this study is to verify the relationship between expectancy confirmation and continuance intention in internet shopping mall. For this objective, we combine information satisfaction and usefulness of decision making with Expectancy Confirmation Model. Data were collected through a survey of respondents who have the experience of purchase in internet shopping mall, and analyzed by using structural equations model. The results show that expectancy confirmation influences information satisfaction and usefulness of decision making, whereas has not an effect on overall satisfaction. Namely the relation of expectancy confirmation and overall satisfaction is mediated by information satisfaction and usefulness of decision making. Finally, intention of contingence usage was found to be formed through overall satisfaction.

With the recent establishment of a ubiquitous environment and the paradigm shift to a smart society, the use of mobile devices, such as smart phones and tablet PCs, has become widespread. Thus, the trend is gradually shifting from using Web-based Instant Messenger to using Mobile-based Instant Messenger. Mobile Instant Messenger refers to a service that allows instant messaging as well as data sending and receiving between individuals with exclusive application programs(mobile Apps), which can be used in portable devices-such as smart phones-with wireless Internet access. Korea`s portal sites, telecommunication companies, and even big companies have all rushed into the MIM market to join the competition. The reason so many companies are showing interest in the MIM business is because it is rising as a core platform to substitute portal sites in the mobile society, and MIM is perceived as the best means to attract and secure users. The intention to reuse or use continually was considered an important factor in maintaining a dominant position amidst such fierce competition, and consequently, most research thus far has reflected such thought. However, the frequent or long-term use of a system alone cannot indicate the definite success of the system, nor guarantee its dominant position in the market. On the contrary, MIM dependence, which goes beyond simple repetitive use and indicates a state where users actually or emotionally depend on a specific system, can better explain the user action. However, not much research has been conducted on dependence. The research results showed that lively message, concise message, message responsiveness, and social belonging significantly affected perceived usefulness. Message responsiveness, Link, and social belonging significantly affected flow. Flow significantly affected MIM dependence, and perceived usefulness did not affect MIM dependence. This study has proven that lively message, concise message, message responsiveness, Link, social belonging and perceived usefulness are important antecedents and mediating factors of MIM dependence. Moreover, this study is significant in that it explains the overall process of MIM dependence, and expands on the variety and scope of research that can be applied to MIM-related studies.

This research aims at developing and distributing models and indexes that can evaluate ubiquitous information projects in order to enhance the objectivity and validity of their evaluation. The research adopts a BSC(Balanced Score Card) concept with four views, economic, policy, social, and technical views. The research induces a model of pre-evaluation and a model of post-evaluation according to each view. In order to secure the validity of the models, they are revised and complemented by obtaining advice through interviews with five experts in related fields, and the validity and application possibility of the indexes are verified by surveying ten people working in those fields. Finally, investigating their weights according to the importance of each view and index, they are evaluated using an AHP (Analytic Hierarchy Process) method.
