Knowledge sharing occurs through voluntary interactions between human actors. In this paper, from the perspective of social interaction, the effect of transactive memory capability and social capital (bridging social capital and bonding social capital) on knowledge sharing intention was analyzed, and tenure was demonstrated as a moderating factor that can strengthen their relationship. Therefore, the results of this study are summarized as follows. First, it was verified that the transactive memory capability had a significant positive effect on the knowledge sharing intention. Second, it was found that the bridging social capital and bonding social capital held by individuals had a significant positive effect on knowledge sharing intention. Social capital is understood to form an individual's voluntary motivation for knowledge sharing. Third, it was verified that the moderating effect of tenure suggested in this study was not significant. Based on the results of this study, implications and future research directions were presented.

The requirements of knowledge customization have increased as information resources have become more various and the numbers of the resources are increased. Even if the method for collecting the information has improved like Really Simple Syndication (RSS), information users are still struggling for extracting and customizing the required information through the Web. To reduce the burden, we offer the dynamic knowledge customization framework by using ontology-based CBR. The framework consisting of three phases is comprised of the conversion phase of web information as a machine-accessible case, the extraction phase to find a case appropriate for information users' requirements, and the case customization phase to create knowledge depending on information user's requirements. Newly, the dynamic and intensity-based similarity is adopted to support timely dynamic change of users' requirements. The framework has adopted to create traveler's knowledge to the level users wanted.

This study examined the effects of scenario-based education for patients with difficulty urination on nelaton knowledge, nelaton confidence, and nelaton catheterization skill ability of nursing college students. The data for this study were collected from May to June 2019, and were conducted for the third grade nursing students located in J city. A non-equivalent control group pretest-posttest design was used in 75 junior nursing college students subjects who were assigned to the experimental group 37 and the control group 38. The collected data was analyzed through the ��2-test, independent t-test and paired-test. There were significant differences in nelaton confidence(t=4.60, p<.001), nelaton catheterization skill ability(t=3.46, p=.001). But scenario-based education was found to be insignificant in the nelaton knowledge of nursing students. Difficulty urination scenario-based education can be used as an effective educational intervention to improve nelaton confidence and nelaton catheterization skill ability. However, in nelaton knowledge, it is necessary to verify the effectiveness of education through additional research.
