  • This study investigated the factors that facilitate knowledge creation of team with the aspect of knowledge management. We considered two characteristics which are team members' psychological characteristics (achievement needs and conflict emotion) and knowledge network characteristics among team members (internal cohesion and external bridging) and verified the relationship between these characteristics and team performance. Furthermore, we examined whether these characteristics have a different effect on team performance according to the mastery climate. This study performed a survey targeting team members in knowledge based firms and 376 final surveys to be used as a sample in this study. The result showed that team members' psychological characteristics and knowledge network characteristics among Team members have an influence on team performance significantly. In addition, the master climate moderated the relationship between team members' psychological characteristics and team performance.

  • The importance of communities of practice(CoP) as an organizational informal unit for fostering knowledge transfer and sharing gains a lot of attention from KM researchers and practitioners. Since most of CoPs are formulated online these days, the credibility or trustworthiness of knowledge contents circulated within a certain CoP should be considered thoroughly for them to be fully utilized safely. Here comes the need for an appropriate trust measuring methodology to determine the true value of knowledge given by unknown people through an online channel. In this paper, an improved trust measuring method is proposed using new trust variables such as level of degrees derived from the relationships among community users. In addition, activeness, relevance, and usefulness of the knowledge contents themselves, which are calculated automatically using a text categorization technique, are also used for trust measurement. The proposed framework incorporates fuzzy set and calculation concepts to help build trust matrices and models, which are used to measure the level of trust involved in specific knowledge artifacts concerned.

  • Emotion is a central feature of social interactions. In this study, we examined age-related changes in emotion expressiveness and emotion knowledge and how young children's emotion expressiveness and knowledge were related. A total of 300 children attending a daycare center contributed data for the study. Observation and interview data relevant to measures of emotion expressiveness and knowledge were collected and analyzed. Both emotion knowledge and expressed positive affect increased with age. Older preschool children expressed positive affect more frequently than did younger preschoolers. Older preschool children also labeled, recognized, and provided plausible causes mores accurately than did younger preschool children. In addition, we tested whether children's errors on the free labeling component conform to the structural model previously suggested by Bullock and Russell (1986) and found that preschool children were using systematic strategies for labeling emotion states. Relations between emotion expressiveness and emotion knowledge generally were not significant, suggesting that emotional competence is only gradually constructed by the child over the preschool years.

  • The purpose of this study is to explore the process of knowledge creation at the infusion stage in IT adoption. Because of the lack of the prior research on the infusion and the process of individual knowledge creation we employed Grounded Theory Method which is a qualitative method for building a theory inductively. Collecting and analyzing data from 13 knowledge workers including medical doctors, project managers, and bankers, a process model is developed through the serial process of open, axial and selective coding. We conceptualized the knlowledge creation at the infusion stage as a social process where knowledge is expressed through private and public justifications. This study also found that organizational politics, top management supports, and organization strategy are important factors facilitating the knowledge creation process.

  • This study extends prior research of knowledge management by proposing how social capital can positively impact the ability of organizations to manage knowledge. The purpose of this study is to examine the relationship between social capital and knowledge management and how both help organizations achieve a sustained superior performance. To serve this purpose, I conducted an extensive survey on 143 Korean firms in diverse industries. Analyzing hypothesized relationships with the data collected, I empirically assure that organizations with high levels of social capital have more knowledge management capabilities than organizations with low levels of social capital and there exist statistically significant relationships between knowledge management and organizational performance.

  • Purpose: This research investigates the differences in knowledge exchange activities and performances between startups and large companies in software industry clusters. Research design, data, and methodology: Six independent factors of human resource information, R&D and technology, marketing knowledge, government support information, strategic knowledge, and cooperation information were extracted to test the firm size effect in the relationships with two performance factors such as satisfaction with industry cluster location and satisfaction with financial performances. Data were collected through a survey of entrepreneurs, managers, and employees and tested by statistical analysis methodologies. Results: Three independent factors of human resource information, R&D and technology, and cooperation information were particularly significant in the relationship with both dependent factors. Strategic knowledge significantly affected financial performance. Knowledge exchange activities were more important in startups than in large companies for all eight factors. Conclusion: Policies for software industry clusters need a different approach for startups and large companies.

  • The purpose of this study was to investigate the levels of knowledge and behavior towards food hygiene among child consumers, examine the factors influencing them, and analyze the causal relationship between them. The data were collected from 521 elementary school students in Youngnam area by a self-administered questionnaire. Frequencies, Pearson's correlation analysis, multiple regression analyses, and path analysis were conducted by SPSS Windows. The results from this study were as follows. First, the level of knowledge towards food hygiene was not particularly high, and the level of behavior was somewhat more than the average. Second, the factors influencing the level of knowledge towards food hygiene were school record (upper and middle), and concerns about food hygiene. In addition, concerns about food hygiene, the frequency of food hygiene education in the family, and the level of knowledge towards food hygiene had an effect on the level of behavior towards food hygiene. Third, in the analysis of the causal relationship between the knowledge and behavior towards food hygiene, school record indirectly influenced the behavior towards food hygiene, and the frequency of food hygiene education in the family directly affected the behavior towards food hygiene. On the other hand, concerns about food hygiene had direct and indirect influence on the behavior towards food hygiene. In addition, the knowledge towards food hygiene showed a direct effect on the behavior towards food hygiene. These results imply that knowledge towards food hygiene is a very important factor to improve the children's behavior towards food hygiene and that parents' concerns and guidance for children are needed.

  • This article described relations between knowledge contents for culture contents. Knowledge contents include academic article, research report, digital replica for old books and digital cultural heritages with a high level of abstraction and complexity. The process of digitalization sets up the clearinghouse for information and knowledge of humanities which can be a critical resource for cultural contents development. Knowledge contents are deliverable of knowledge-information hierarchies. The knowledgeinformation resource management plan doing by Korean Studies Advancement Center shows the most of the hierarchies. As a result, this paper shows that the process of knowledge-information development and the process of cultural contents development are in a series of continuous process.With the help of information technology.
