Purpose - There are many antecedences and consequences of the positive emotions of customers. The purpose of this research is to examine how Chinese service companies improve not only the positive emotions of customers but also the quality of life through effective verbal and nonverbal communication. Furthermore, we tried to analyze the moderating role of negative expectancy disconfirmation perceived by customers in those causal relationships among the variables. Research design, data, and methodology - The eight hypotheses were proposed and we tested them empirically in this research. Four hypotheses were about the relationship among communication, positive emotion, trust and quality of life. The other four hypotheses were about the moderating effect of negative expectancy disconfirmation in the causal relationships among four variables such as communication, positive emotion, trust and quality of life. A total of 356 samples who had visited the service companies in China were surveyed and 8 hypotheses were tested by empirical analysis using SPSS and AMOS. Results - The results of this research are as follows. First, positive verbal communication and nonverbal communication of employees in the service company have a positive effects on the positive emotions of customers. Second, positive emotion has a positive effect on the overall quality of life on the customer side as well as the trust on the corporate side. Third, negative expectancy disconfirmation perceived by customers has negative moderating effect in the causal relationship between employees' positive verbal communication and customers' positive emotion, and it also has a negative moderating role in the causal relationship between customers' positive emotion and overall quality of life. Conclusions - Based on these results, there can be such implications as follows. First, managers and employees of service companies can induce positive emotion of customers through effective communication. Second, service companies should try to improve not only the corporate-side performance like trust but also the customer-side performance like quality of life. Third, it will be significant for them to lower the level of negative expectancy disconfirmation for the purpose of improving not only the positive emotions of customers but also the quality of customers' life.

Cyworld was successful where others have foiled because of its unique and profitable business model that relies on the purchase of digital items and its ability to mimic and recreate aspects of face-to-face interpersonal relationships among the members of the online community. The purpose of this study is to understand how the needs for self-presentation and needs for affiliation influence digital item purchase intention, and to analyze the moderating roles of gender and purchase experience in those relationships. Based on the theoretical framework including self-presentation theory and theory of affiliation, we developed the research model and proposed ten hypotheses. A survey was conducted with 225 members of Cyworld. The research model and the related hypotheses were tested using Amos. As the result of the analysis, eight hypotheses out of ten hypotheses were supported. In particular, digital item purchase intention in virtual world was found to be affected by both members' needs for self-presentation and needs for affiliation. We also found that the needs for self-presentation is significantly influenced by innovativeness of members, self-efficacy, and group norm. Also, needs for affiliation is significantly affected by self-efficacy, group norm and perceived value. Furthermore, the results indicate that 1) moderating effects of gender on those relationship is supported; and 2) moderating effects of purchase experience is partially identified. This study provides several implications for academic community and practitioners to understand why the community members pay real money for their digital items as well as how the sales of digital items can be increased in online communities. Some study limitations and future research directions are also discussed.

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.

Behaviors of organizational members can be classified as two types. One is behavior required to perform formally given job. The other is a various kind of behavior taken voluntarily but not required directly and formally to perform job. The former can be called as in-job behavior while the latter can be called as extra-job behavior. Many organizational scientists so far, have focused on investigating in-job behavior. Yet, from a decade, organizational researchers have recognized that in-job behavior alone can not explain sufficiently job performance or organizational effectiveness Thus. they have paid attention to extra-job behavior, which is generally called as organizational citizenship behavior. Existing studies of organizational citizenship behavior have three types : First type is studying the concept and components of organizational citizenship behavior. Second tope is studying the determinants of organizational citizen-ship behavior and relationships with it. And third type is studying relatioships between organizational citizenship behavior and job performance. This study, therefore, have purposes as follows : Firstly, this study designs a comprehensive model in the below figure and generates inclusive hypotheses about relationships among antecedents, intermediate factors, and the components of organizational citizenship behavior. Secondly, this study investigating empirically such relationships and draws a picture of mediation roles of the intermediate variables. To design the model and generate the hypotheses, this study conducted a comprehensive literature survey on organizational citizenship behavior. To test the hypotheses, this study collected data from 847 employees at 12 large genral hospitals in Pusan area through a questionnaire survey and conducted the three step mediated regression analysis using the SAS-PC Package.

The knowledge society has come to where the knowledge is the source of wealth contrary to the traditional era that labor and capital were the source of wealth. Thus, corporate is accelerating to introduce the knowledge management and to establish the knowledge management system (KMS) in order to effectively manage the knowledge that can be the source of their competitiveness. The purpose of this paper is to identify the factors which affect knowledge sharing and to prove empirically their relationships with the KMS performance. A survey was conducted and data were collected from 220 respondents of 19 organizations which have adopted KMS. Research model and related hypotheses were tested using PLS Graph 3.0. As a result of data analysis, seven hypotheses out of eleven hypotheses were supported. In particular, knowledge sharing is significantly influenced by those knowledge sharing factors such as openness, trust, training, reward system, perceived usefulness, and communication channel. Also, individual impact is significantly affected by knowledge sharing. This study is expected to provide a sound basis for understanding the importance of knowledge sharing to gain organizational as well as individual competitiveness and exploring ways to effectively share knowledge through enhancing the use of KMS in organizations.
