This study examined how firms responded to the articles regarding the prohibition or correction of discrimination against fixed-term workers in the 'fixed-term worker protection law', which has been effective since July of 2007 in Korea. Data used cone from the Korean Workplace Survey, and a difference-in-differences method was employed for the identification of the causal effect, noting that the 'discrimination prohibition law' has been applied to firms over stages based on their sizes. The empirical results show no strong evidence that the law played a positive role in reducing differentials between permanent workers and fixed-term workers in the areas of wage and various employee benefits, including the provision of severance pay, annual leave, and 4 major social insurances for fixed-term workers. A more thorough future analysis on the causes of the insignificant impact of the law in some employee welfare benefits, along with supplemental policies, is needed to have the law achieve the desired goal of removing discrimination at the workplace.

The purpose of this study was to investigate the relationship between media richness, media usefulness, media experience and media decision in order to identify factors that determine the media of school library in solving performance evaluation tasks. For this purpose, 132 primary and middle school students were surveyed and their structural equation was set up by hypothesis setting, validity test, and causal model. As a result, it was confirmed that media experience of school library is a major factor in media decision. Also, media richness and media experience appeared to influence media decision through media usefulness. The analysis implies that school library is centered on teaching - learning process and evaluation, so information literacy education should be carried out in school curriculum and school library is required to provide students experience on media as the center of school education.

In a competitive organizational environment, members view completing tasks to perfection without mistakes as the requirement for success and good evaluation from others. However, unrealistically strong perfectionism can have negative effects on members' psychological states and organizational performance. This study focuses on evaluative concerns perfectionism, the negative aspect of perfectionism, based on positive psychology theory to explore the positive mechanism that comes into place in the process of strengthening organization members' resilience. For this purpose, we performed a moderated moderation analysis to investigate whether the moderating effect of leaders' social support (primary moderator) is moderated by their emotional intelligence (secondary moderator). To verify our research model, we conducted a two-part survey of 252 employees in various industries with a time interval to minimize the common method bias. Job rank and positive affectivity were set as control variables to identify the clear causal relationship among variables. Our findings showed that first, evaluative concerns perfectionism reduced resilience; second, leaders' social support positively moderated the relationship between evaluative concerns perfectionism and resilience; and third, the leaders' emotional intelligence positively moderated the two-way interaction between evaluative concerns perfectionism and the leaders' social support, confirming a moderated moderation. Our findings suggest the need for leaders to assume multidimensional roles to enhance the positive traits of organization members, especially in today's complex business environment. The implications of our findings are further discussed in relation to knowledge management and the development of organization members who exhibit evaluative concerns perfectionism, along with suggestions for future research.

E-authentication is one of the key functions for electronic transactions with the identification function made through the information systems. With the abolition of the mandatory use of public certificates, various private e-authentication services have emerged, and are developing to provide various additional services in addition to e-authentication. In this study, we explored the factors that affect user satisfaction with e-authentication services, compared the relative influence among the factors that we explored, and produced implications that could contribute to strengthening the competitiveness of e-authentication services. Based on the characteristics of e-authentication service, we searched and found four factors such as availability, convenience, added functionality and security. After that, we established and analyzed our research model to analyze the causal relationship between these four factors and user satisfaction. The analysis results showed that availability, convenience and security had significant effects on user satisfaction, but added functionality had no significant impact. In addition, compared to availability and convenience, security had a very strong impact on user satisfaction. This study suggests that e-authentication service providers should make efforts to make users aware of the usefulness of additional services while enhancing security.

The purpose of this study is to verify the causal relationship between social withdrawal and peer alienation among Korean children. The survey study participants were 2,110 children in 2nd, 3rd, 4th, and 5th grades. The 5-year longitudinal data (Korean Child and Youth Panel Survey; KCYPS) of 1st grade elementary school student cohort was used. Latent Growth Modeling was applied to analyze the causality over time of social withdrawal and peer isolation. The results revealed that the trajectories of children's social withdrawal decreased over time. Children's social withdrawal showed significant individual differences in terms of initial value and rates of change. The initial value and slope of children's social withdrawal had an effect on the peer alienation in the 3rd grade; however, there was no significant effect on the peer alienation in the 5th grade.

The objective of this research is investigating the mediating effect of job engagement on the relationship between job autonomy and innovative behavior in public organizations. Major findings from Structural Equation Model analysis demonstrates that the variable 'job engagement' took a positive role between job autonomy and innovative behavior. From theoretical point, this result provides the empirical evidence of causal relationship in the three components of attitude-cognition, emotion, and action, which contributes to the advancement of action theory. Some policy implications can be drawn from the empirical findings. Firstly, job autonomy need to be seriously considered as a strategic instrument for the encouragement of innovative behavior. Secondly, job engagement of employees need to be more carefully monitored to stimulate the innovative behavior in the public organizations. In public organizations, enhancement of innovative behavior can not be achieved from institutional arrangements. Provision of job autonomy is more effective method of behavior change than performance management approach.

The purposes of this are to figure out the amounts of leisure time of full-time homemakers and to find out leisure time factors contributed to raise the quality of life. The major findings are the followings: 1) Full-time homemakers spend 353 minutes(5.9 hours) on the average per day on the leisure. Time for active leisure(creative activities, sports activities, spectator events, going to the party, and so on) is 70 minutes, while that for passive leisure(watching TV. listening to the radio, reading newspapers. magazines. Books, chating, relaxing, card playing) is 283 minutes(4.7 hours). The passive leisure is the main type of spending leisure time. 2) The total leisure time of wives is significantly related to SES factors. The higher the wives age and education, the family income, and the age of the latest child, the more the wives total leisure time. But the more the family numbers, and the child numbers, the lower the leisure time. Active leisure time is highly rela ed to family income, while passive leisure time is considerably family composition. 3) The wives are mostly satisfied with their lives. The wives perceptions of the quality of life is related to wives's education, house type, and family income. 4) The wives total leisure time is not related to the quality of life. There is a positive correlation between active leisure time and the quality of life, while a negative relationship is between passive leisure time and the perception of the quality of life. 5) In analysis of causal model, it appears that family income and active leisure time of wives directly affect the perceived quality of life. The more the family income and active leisure time, the higher the quality of life. it is implicated for wives to take and active attitude and to reduce, if possible, passive leisure time and to increase active leisure time.

The purpose of this study is to investigate the effects of person-organization fit and person-job fit on occupational commitment, organizational commitment and turnover intentions among cooks in the foodservice industry. Data were collected by a total of 210 cooks at restaurants in the Seoul and Kyunggi area. The analysis of AMOS was used to test the causal model. The results indicate that the person-organization fit was positively related to occupational commitment and organizational commitment. The person-job fit was also found to correlate positively with occupational commitment and organizational commitment. Occupational commitment was positively related to turnover intentions while organizational commitment was negatively related to turnover intentions. Implications of the results and limitations of the study were discussed.

Objective: This study was performed to investigate the prevalence of impaired fasting glucose (IFG) and its related characteristics among healthy adults in some Korean rural areas. Methods: We conducted a cross-sectional study using the data from 1352 adults who were over the age 40 and under the age 70 and who were free of diabetes mellitus (DM), cardiovascular diseases and other diseases and who participated in a survey conducted as part of the Korean Rural Genomic Cohort Study. IFG was defined as a serum fasting glucose level between 100 and 125 mg/dL. Results: The prevalence of IFG was 20.4% in men, 15.5% in women and 12.7% overall. Multivariate logistic regression analysis demonstrated that the independent risk factors for IFG were male gender, having a family history of DM, the quartiles of gamma glutamyltransferase and high sensitive C-reactive protein and the waist circumference. The homeostatis model assessment for insulin resistance was very strongly associated with IFG. The prevalence of metabolic syndrome (MS) and MS components was higher in the subjects with IFG then in those with normal fasting glucose (NFG). Conclusions: The result of study could supply evidence to find the high risk population and to determine a strategy for treating IFG. Further research is needed to explain the causal relationship and mechanisms of IFG.

Entrepreneurship and innovation are highlighted as a way to overcome limitations and risk factors caused by today's uncertain business environment. As the uncertainty in the business environment increases, organizations are required to adapt to ever changing business dynamics. For this adaptation, entrepreneurship and innovation are crucial factors. This study proposes a model to explain a structural relationship between entrepreneurship, technological innovation, and innovation performance. The unit of analysis focus is small and medium-sized businesses. Empirical results show that there are positive causal relationships from entrepreneurship to technological innovation, and from technological innovation to innovation performance. Additionally, no direct relationship from entrepreneurship to innovation performance can be achieved through innovation activities such as technological innovation. This study points out the importance of entrepreneurship and technological innovation, and suggests that entrepreneurship along with technological innovation should be internalized as business practices leading to increased performance.
