The objective of this study is to identify the impacts of communication reinforcement on performance of learning in Web-PBL. Communication reinforcement is defined as the combination of information sharing and co-construction. As factors facilitating communication reinforcement, we propose learner's characteristics, task characteristics, and group characteristics. Learner's characteristics are collaboration-orientation, openness, holistic approach, and online community-orientation which reflects e-learning environment. Collaboration-oriented tasks as group projects were developed and given to groups with 5-6 members. The group characteristics are categorized into 'horizontal' and 'vertical', according to the patterns of communication between a group leader and members. To verify empirically the proposed research model, an experimental design was performed to learners who took on-line and off-line courses with group projects. We found important results as follows; First, field dependence has positive impacts on information sharing, and online community-orientation has positive impacts on co-construction. These results correspond with prior studies on relationship between field dependence and collaborative learning. Second, collaboration-oriented task directly impacts on information sharing, and indirectly affects co-construction, This result implicates that information sharing is pre-requisite of co-construction. Third, 'horizontal' was identified as a factor giving positive effects on information sharing and co-construction. This result implies that horizontal communication is very important to facilitate communication reinforcement.

The objective of this research examines the relationships among privacy concerns, self discrepancy, and sense of virtual communities. According to the relevant literature review, we considered information privacy concerns factor as information collection, control, and awareness of privacy practice, and sense of community factor as membership and immersion on virtual communities. This research surveyed for the online community user and employed hierarchical regression model for the moderating effect test. The results of empirical analysis turns out that awareness of privacy concerns practice has negative impact on the self discrepancy, on the other hand, information collection and control factors do not affect. The next finding is internet use duration has moderating effect on the self discrepancy with information control and awareness of privacy concerns practice. The last findings are self discrepancy affect on the community membership and does not affect on the community immersion. It could be a good guide line for the operational direction on virtual community.

The model consists of variables such as social tie and perceived usefulness as predecessors of eWOM, four dimensions of cultural orientation (Horizontal Individualism, Horizontal Collectivism, Vertical Individualism, Vertical Collectivism), and eWOM. The model was tested empirically using the PLS (partial least squares) structure equation model. Survey was conducted for online community users in South Korea. Data was statistically validated whether fits on research model. The study results reveal that Social Tie have a positive effect on Perceived Usefulness. Social Tie and Perceived Usefulness have a positive effect on eWOM. 3 of cultural orientations (HC, VI, VC) have a positive effect on Social Tie. Only one of cultural orientations (HC) have an negative effect on Perceived Usefulness. Especially, horizontal collectivism (HC) shows strong correlation with perceived usefulness, whereas vertical collectivism (VC) shows weak correlation with perceived usefulness andvertical individualism (VI) shows strongly correlation with social tie, whereas horizontal individualism (HI) shows weak correlation with social tie. Based on the study results, customized service strategy could be formulated according to the different vertical styles and various eWOM factors.

Collective intelligence can be an influential factor of decision-making based on collaboration and information exchange between individuals. Our study explores whether collective intelligence can mitigate the loss aversion effect, bias and error in human judgment, and collective intelligence in online communities can reduce the loss aversion effect. Our community settings display both individual-level and group-level loss aversion effect, investigate effective collective intelligence characteristics like investment commitment, participant experience. Using a multi-method approach our research comprises a web-based experiment with 100 participants investing 3 situations from a real-world community, data from a survey measuring loss aversion behavior of participants. The results suggest the loss aversion effect mitigates under the online-circumstance. Overall, our results suggest that, while collective intelligence mitigates the loss aversion effect, participants do not transfer these results to other settings.

This study proposed that a relationship exists between individual emotions and knowledge sharing (KS) intentions in competitive online advice communities. Through statistical analysis of 220 valid questionnaires collected from qualified community members, we found that individuals' intentions to contribute knowledge were enhanced by playfulness and reciprocity, while their intention to seek knowledge from others was facilitated significantly by needs fulfillment, sense of competition, and playfulness. In addition, we found that playfulness was a common factor that affected the intention to seek, as well as to contribute, knowledge. Specifically, playfulness was a highly significant individual emotion that affected both individuals' intention to contribute and seek knowledge, while reciprocity was significant primarily in individuals' intentions to contribute knowledge. Needs fulfillment and sense of competition were significant emotions that affected primarily individuals' intentions to seek knowledge. Interestingly, the factors that affected the intention to seek knowledge were consistent both in all participants and in the high-level fear group. However, in the low-level fear group, playfulness influenced KS intentions.

Purpose: The aim of this study was to investigate the educational status and needs of premature birth prevention, and to identify factors associated with preconception health behaviors. Methods: The study design was a crosssectional descriptive study. Data were collected through an online questionnaire survey, and the subjects were 192 women of childbearing age in Korea. Data were analyzed using the Mann-Whitney U test, Kruskal-Wallis test, Spearman's correlation coefficients, and multiple regression. Results: The proportion of subjects who received education on premature birth prevention was 8.9%, and 75.5% of subjects answered that they needed education on premature birth prevention. They demanded education through online media, small groups, cases, cartoons (webtoon) with stories, pictures, and videos. A related factor of preconception health behavior was self-efficacy for high-risk pregnancy health care (β=.20, p=.012), which accounted for 8.2% of the total variance related to preconception health behavior. Conclusion: There was a need for more development of education programs to prevent premature birth for women of childbearing age. Its education programs should be applied with online, small group activities using various educational media. It is also required to promote preconception health behavior through self-efficacy for high-risk pregnancy health care.
