This study addressed trust to collective intelligence for explaining the affecting factors to the intention to use of collective intelligence by dividing the object of trust into a Web site and an information source group. We explored the factors affecting user's continuance intention toward collective intelligence in the view off trust building. We made a well-structured survey of our proposed model and gained 205 cases. We analyzed the proposed research model empirically using partial least square method. The findings are summarized as follows. First, all key factors (relevance, timeless, completeness, understandability) composing of collective intelligence quality have a positive and significant impact on confirmation. Second, confirmation has a significant impact on trust toward a Web site, as well as toward an information source group. The last is that trust toward a Web site influences on continuance intention, whereas trust toward an information source group doesn't.

Business Process Change(BPC) is regarded as a salient factor to improve an organizations' efficiency in the current fast-changing business environment. Despite the tremendous popularity and great potential, the field of BPC adoption is littered with remarkable failures. Consequently, there have been many studies that have tried to identify the environmental factors that lead to successful BPC. However, most of them have not considered the effect of the interaction between the environmental factors on BPC success. According to Klempa(1995), the fit between environmental factors of a company may have the impact on its BPC success. Under this background, this paper empirically examines the effects of the fit between the type of BPC and the organization's culture on the success of BPC. Organization's cultures, organizational learning, as well as knowledge sharing are the dominant causes that have impact on the innovation characters of organization. Whether an organization has safety-oriented homogeneous culture or it has the change-oriented heterogeneous culture may have impact on its implementation of BPC. Also the implementation of BPC may be affected by whether the organization adopts the improvement project which accompanies only small changes or it adopts the innovation project which leads to critical changes. Thus, we analyzed the effect of the fit between the organization's culture and its BPC type on BPC success by using the survey data collected from the companies that have adopted BPC. The findings presented in this paper show that the organization having heterogeneous culture practicing innovation project and the organization having homogeneous culture practicing the improvement project resulted in the excellent BPC success.

This study tried to find the source of the success of on-line game sites and the way how the absorption and the satisfaction would have the relationship with the intention-to-use of on-line game sites. The primary purpose of this study is to establish the empirical model on the determinants of on-line game sites. The research model of this study will have insights which are trigger to the higher dimensions on the model and to the importance of the evaluation criterions of game sites. The suggestions of the study are as follows. First, the precedent factors of research model were tested for the commonality with explorative factor analysis and then tried the confirmative factor analysis. Thus, the determinants in this model will be used for further study without an evaluation. Second, the factors which have a most significant effect on the mediating factor like the absorption are a skill of user and an activity of community. Furthermore, the information quality of game sites was most significant in the satisfaction of user. Third, the most factors which included in the research model were significant to intention-to-use, however, the system quality did negatively significant.

The rapid pace of adoption of mobile handsets has created new mobile financial services. The success of mobile financial information systems will depend on consumer self-efficacy and a sound business model. Self-efficacy has been described as the belief that one is capable of performing in a certain manner to attain certain goals. This is directly related to consumer behavior, but it also affects consumer behaviors indirectly through its impact on goals. And self-efficacy influences the challenges that people take on as well as how high they set their goals. The objective of the study to investigates the effect of self-efficacy on mobile financial information systems. In order to do that, self-efficacy, mobile financial information systems reliability, mobile financial information systems use intensity are conceptualized by survey questionnaire. Our empirical analysis based on 462 survey data shows that self-efficacy effects on mobile financial information systems quality. In addition we also found that self-efficacy effects on mobile financial systems reliability and usage intention. And we found that mobile financial information systems reliability effects on mobile financial systems use intention. And we also found that mobile financial information systems usage intention effects mobile financial systems quality.

Recently, Information System (IS) development projects such as the next generation IS project of the financial business domain have shown tendency to become large and complex. Accordingly, a large number of enterprises have introduced a Project Management Office (PMO) to successfully manage multiple complex large-scaled projects. Many researches and empirical studies have proved the positive results of PMO-based projects. For example, most PMO-based projects have been accomplished successfully without exceeding the planned deadline and budget. However, even in the case of PMO-based projects, participants are still supported by legacy Project Management Systems (PMS) developed without considering the PMO. It implies that recent large projects are hardly performed efficiently because of the large gap between the legacy PMS tools developed only for single small projects and the real process of PMO-based project management. Therefore, we attempt to design and develop a PMO-based PMS in which the role and responsibility of PMO are completely implemented. To demonstrate our systems practicality, we applied the devised system to the real project management cases of "K" bank in The Republic of Korea. According to the results of case analysis, all of the four projects supported by our PMO-based PMS have been completed without exceeding planned deadline and budget, and the quality of their final outcome is appraised to be superior.

Recently Micro-blog service is used quickly in our life with dissemination of Smart-phone. This study performed based on a view that there is a difference of user's intention to reuse Web-blogs & Micro-blogs. This study also based on the existing motive theory for using which considers five factors-information, entertainment, interaction, personalization, and convenience. The AMOS structure equation used for the analysis of users' revisit intention. The results of the study shows that Micro-blogs are influenced by entertainment, personalization, and convenience. On the other hand, Web-blogs are influenced by entertainment, and personalization.

Recently, the development of ICT(information & communications technology) with the advent of new media paradigm shift in learning has brought a dramatic impact on the competitiveness of universities. The previous studies on the academic performance of e-learning mainly targeted on e-learning users, studying additional synchronization and system quality factors to measure academic performance. This study empirically analyzed the learning flow and academic performance considering both DeLone & McLean model system quality and synchronizing factors based on ARCS model. Relating to quality and synchronization factors, the academic performance of e-learning system was tested, and the difference between learning flow and academic performance was also analyzed based on time-series data, by the test difference(in the beginning, during, and final of the semester). The results of the study are as follows. First, the study shows that both system quality and synchronization directly affected the learning performance. Thus, when designing e-learning system, it is necessary to consider these two factors at the same time. Second, the indirectly mediating effect on the system quality and synchronization factors turned out to be significant in learning flow. Third, the result of regression analysis on the contents of utilizing dummy variable presents that the teacher's explanation has greater influence than multimedia has to the academic performance, and furthermore, the test difference showed no significance. Further research should be undertaken to consider the learner's degree of acceptance which reflects various aspects for building m-learning or u-learning.

With the rapid growth of internet technology, social commerce has played an important and central role in the online shopping area. Thus, we focus on the factors that influence on the adoption of social commerce. This study analyzes the relationship between perceived risk and the shopping motive in social commerce, and investigates whether the shopping motive significantly impact the purchase intention of the social commerce. The perceived risk is comprised of social risk and psychology risk, and the shopping motive is formed from personal motive and social motive. Finally, we analysis a moderating effect of collectivism. The results indicated that the personal motive was negatively affected by the social risk and psychology risk, and social motive was negatively affected by the psychology risk. The social risk and psychology risk had negative effect on the purchase intention, and personal motive and social motive had positive effect on the purchase intention of the social commerce. Finally, low collectivism seems to have the negative effect of the purchase intention by the perceived risk. The implications of integrating perceived risk and shopping motive into the proposed social commerce adoption model are discussed.

Although e-commerce is growing fast, e-commerce consumers are still under higher risk and uncertainty in the comparison of the traditional commerce's. Consumer review boards of online shopping malls are good measures to help buyer's decision making, and should be managed effectively by sellers. We formulate the research model on consumer trust formation on seller managed web review boards on the background of previous literatures on e-WOM and trust. Our data analysis with 368 samples shows seller's reputation, e-service quality, perceived reviewer's benevolence and ability have significant positive effect on the trustworthiness of the board. Product involvement shows weak negative moderation effect on the relationship between perceived reviewer's benevolence and trustworthiness of review boards.
