In the field of education in Korea, University Information Disclosure System was conducted forcibly in December 2008 by Ministry of Education, Science and Technology. As a result, information quality provided to the user has been improved dramatically. Based on the preceding studies of information success model, the purpose of this study was to prove empirically three facts on the organization's performance, user's attitude, and gaps between two factors by improvement in the quality of information. To accomplish the purpose, literature review and statistical analysis were done using the university evaluation data published by JoongAng Daily from 2007 to 2011. The results of this study showed that the information quality had positive effect on organization's performance, user's attitude like a reputation, and the gaps between two factors. The results of this study had a great expectation for the role of offering useful insight and information in the field of information system and education.

The goal of supply chain integration is to improve the effectiveness and efficiency of supply chain for creating customer values. Supply chain integration can be classified into IT integration and structural integration. Also, structural integration can be collapsed into three dimensions: internal, supplier and customer integration. In this study, we investigate the relevance between customer value and supply chain integration. To explore the current study, we collected from 73 Korean firms. The results are as follows: First, customer value has a positively significant effect on IT integration. Second, customer value influences on customer integration but does not has an effect on internal and supplier integration. Third, IT integration improve internal, supplier and customer integration. Finally, each of structural integration positively influences firm performance. These results indicated that declaration of customer value is important factor in supply chain integration.
A Study on Acceptance Promotion of Information Systems under the Semi-Mandatory Circumstance: From the Perspective of Switching Costs Applied to the KMS of a Public Organization

The purpose of the study is to propose the plans promoting IS acceptances under the circumstances where the IS usage is semi-mandatory. Since the IS usage is critical to secure the organization's competitiveness, many researchers have endeavored to investigate the factors in promoting IS acceptance. While TAM(Technology Acceptance Model) has been generally applied under the voluntary circumstance, under the mandatory circumstance did many researchers come to realized the limit of applying the TAM on IS acceptance. This resulted in various research trials to identify the IS acceptance under the mandatory circumstance. However, no research to promoting IS acceptance under the recommend circumstance where the corresponding users are recommend to the IS rather than alternative systems exits. The study applied the concept of switching costs to the research model, identified users' acceptance variations, and finally proposed the promotion plans for IS acceptance. The findings illustrate that IS dependence levels tend to be increased when both user satisfactions from a psychological perspective and monetary benefits from an economic perspective make the switching costs higher. The study stresses that organizations should provide information systems which reduce users' time, costs, and endeavors in performing their tasks, rather than require to use them by compulsion.

With emergence of smart technologies(e.g., smartphones), Location-Based Services(LBS) are expected to provide more enhanced values utilizing consumers' personal information than other smart services. However, in contrast to existing smartphone applications, LBS could raised severe consumer's privacy concerns because of rapidly changing information sensitive to consumers. In this context, the purpose of this study is to explore relationships among privacy concerns reduction, trust and intention to use LBS by examining the effect of precedence factors(social presence, reputation, mobile literacy, ability of information control) of privacy concern reduction. In addition, the study investigates the role of personal innovation as a moderating effect between privacy concern reduction and intention to use LBS. The results showed that the proposed precedence factors of privacy concerns with a exception of Mobile Literacy had a positive impact on privacy concerns reduction that then positively affected trust and intention to use LBS. In addition, the relationship between trust and intention to use LBS was significantly supported. Finally, personal innovation as a moderating effect significantly influenced the relationship between privacy concern reduction and intention to use LBS. This study is expected to be a reference for a subsequent study about the spread of LBS application of smartphone. Also, the finding of this study is meaningful for helping service direction to firms providing LBS.

Given the rapid growth of social network services (SNS) such as Facebook and Cyworld, it is important to understand SNS users' decision-making processes such as purchasing and continuance intention. Especially, as a number of SNS providers such as Cyworld and Habbo Hotel recognize the sales of digital items as the main source of their profits, it is critical to in-depth understand SNS users' purchasing behaviors. In this regard, this study explores continued usage behaviors and purchase behaviors of digital items in an SNS environment using a longitudinal research method. This paper develops a theoretical model to deeply understand the key drivers of purchase behavior of digital items through constructs prescribed by two established research streams on information systems, namely continuance usage and habitual usage. Moreover, this study examines the effects of actual and ideal self-image congruity on SNS continuance intention and habit. The research model was tested by using survey data collected from 307 users who have experience with Cyworld. The analysis results show that SNS actual usage directly influence purchase behavior of digital items. SNS users' continuance intention and habit are key drivers to enhance the level of actual usage of the SNS. Both actual and ideal self-image congruity play a key role in enhancing continuance usage and habitual usage. The implication of research and discussions provides reference for SNS providers in marketing and IT strategy.
The Direct Effects of Cognitive Absorbtion on the Automatic Use of Information Technology : Proximal and Distal Effect

According to previous studies, the effect of intrinsic motivation related variables such as cognitive absorption (CA) on the use of information technology(IT) should be mediated by the conscious intention. However, CA, which is a thought of previous emotional experience, a deep involvement with a software, may be one of environmental cues stimulating the use of IT independently of conscious intention. The objective of this study is to show the direct effect of CA on the automatic use of IT. For this purpose, as well as the relation between CA and use, two relations, CA-intention and intention-use, were also suggested as hypotheses, which will show that conscious intention would not fully mediate the relation between CA and automatic use. Moreover, for seeing the effects of CA as time passes, the proximal effect, which is short term and transitory effect, and the distal effect, which is long term and lingering, were simultaneously included in hyptheses. Finally, the effect of past use was also suggested as a hypothesis which aimed to show that automatic use would be controlled mostly by habit rather than not only intention but also CA. For the empirical validation of the hypotheses, 174 users of 'Cyworld', one of most influential social network services, were longitudinally surveyed, which showed that the hypotheses were accepted.

In this paper, we identified the factors influencing on the continuous use intention of social commerce and analyzed the proposed model empirically using structural equation model, which was developed by considering hedonic and utilitarian shopping value, trust, satisfaction, familiarity, social influence, and perceived price. We collected data for this study by surveying the consumers who had an experience of purchasing through social commerce. An analysis of 212 respondents indicated that utilitarian and hedonic shopping value influenced on satisfaction as both of shopping value are significant statistically. Social commerce gives more attraction their consumers by reducing the price to half, whereas they are expected to present playfulness of shopping. Familiarity, social influence, and perceived price are influential factors in a purchase of social commerce sites. We discuss the implications of our findings for both theory and practice.

One of them is online community which is popular among this modern society. However, it is not appropriate to suggest that online community is solely for personal usage or solely for work-related usage. The usage of online community goes beyond only one purpose. On the other hand, our daily activities whether personal or work-related activities are usually accompanied with preconception ideas whether it is a fun activity or not. However, even with this preconception, individuals are still enjoying themselves while doing activities that are considered as boring or mundane. Furthermore, individuals are really into the activities that they forgot about their surrounding and found themselves being in flow while conducting these activities. Unfortunately, there is little research done in South Korea addressing this emotion related factors. Because of that, more research concerning emotion related factors need to be conducted to better understand users behavior especially in online environment. With regards to that concern, this research studied two distinct everyday activities which are studying and playing games in online community. It is expected that when an individual feels more enjoyable and feels more comfortable, it will be more likely for them to be more satisfied. This satisfaction will lead them to being in a flow state. Hence, this study proposed three hypotheses. In order to investigate these three hypotheses, studies were conducted in two stages. The first stage was conducted in order to derive the implicit knowledge about fun from the participants. The second stage was done by an empirical study. It was conducted with two sample groups. The first group is the study group and the second group is the play games group. There were asked a set of questionnaires related to their enjoyment, comfort, satisfaction and flow while conducting the relevant activity. The results showed that both groups reached the state of flow regardless whether they belong to the study group or play games group. Therefore, the preconception idea about an activity does not promote or prevent individuals from feeling enjoyment, feeling comfortable and achieve satisfaction while conducting those activities.
