While the importance of the service industry has increased at the national economy level, the service rate and job satisfaction of the flight attendants in the aviation service industry are not high. In this regard, this study aims to recognize what factors can reduce their job stress in the emotional work environment, and how job stress affects their attitude and job performance. More specifically, the current study tries to investigate how flight attendants' positive psychological status affect their job stress, organizational commitment, and knowledge sharing in the aspect of job performance. The main five constructs in these interrelationships include the flight attendants' positive psychological capital, leader-member exchange(LMX), job stress, organizational commitment, and knowledge sharing. This study conducted a quantitative research with 390 questionnaire for flight attendants, and analyzed the data using SPSS/PC version 20.0 and structural equation modeling program of AMOS 20.0. The findings show that the favorable leader-member exchange relationship between flight attendants plays a significant role in lowering job stress, while high job stress has a negative effect on organizational commitment and knowledge sharing. The result also shows that personal positive psychological capital acts as a trigger to influence other factors. Therefore, this study suggests that it is essential for airlines not only to promote an organizational system to support the flight attendants' emotional work but also to maintain a positive psychological state for securing competitive human resources.

The evolution of IT facilitated the communication and knowledge sharing between the social network service (SNS) users. When the more information about SNS users had been posted in SNS site, SNS users had sometimes exposed in the risk of privacy invasion. To remedy this problem, we had introduced the information control mechanisms from the prior studies in data management to the SNS area and empirically validated the effect of these mechanisms in this research. Three information control mechanisms had been elected as access control, reference control and diffusion control. We had conducted a survey to the Facebook users which is the most famous SNS site. 459 data had been gathered and analyzed by PLS algorism. As the results, reference control and diffusion control has significantly increased the trust on SNS providers and decrease the privacy concern. This change could significantly affect on the satisfaction with the SNS site and knowledge sharing intention of SNS users. This study could introduce the new perspective about privacy protection issues in SNS area. Also, the information control mechanisms suggested in this study could contribute to make more robust privacy protection mechanisms in SNS site in practice.

The study has compared the effects in SNS-utilized instruction that each of self centric activities and social interaction added social activities affected self initiative, attitudes and self efficacy to information technology respectively. The research methods utilized the pre experimental design as nonequivalent experimental group. The data was analyzed by paired t-test and content analysis. The results showed that the SNS class utilized self-centric activities were effective in self-initiative and attitudes toward information technology, while social interaction added social activities were effective in not only self-initiative and the attitudes of information technology but also self efficacy of information technology. And content analysis of the effects of the education showed that information sharing, instancy and accessibility were advantageous but information security and privacy issues were problematic. That is, it was confirmed that when self-centric activities and social interaction activities were practised simultaneously in SNS-utilized instruction, the self initiative which learners planed and executed by themselves, the attitudes and self efficacy of information technology which were able to enhance learning ability and to show satisfaction to individual learning were improved.

Internet is a part of our common life and tremendous information is cumulated. In these trends, the personalization becomes a very important technology which could find exact information to present users. Previous personalized services use content based filtering which is able to recommend by analyzing the content and collaborative filtering which is able to recommend contents according to preference of users group. But, collaborative filtering needs the evaluation of some amount of data. Also, It cannot reflect all data of users because it recommends items based on data of some users who have similar inclination. Therefore, we need a new recommendation method which can recommend prefer items without preference data of users. In this paper, we proposed the apparel coordination system using personalized preference on the semantic web. This paper provides the results which this system can reduce the searching time and advance the customer satisfaction measurement according to user's feedback to system.
