This study attempted to examine the relationship between pygmalion leadership and the organizational commitment among hospital employees, and the mediating effect of the leader-member exchange (LMX) on their relationship. For this purpose, we designed structured self-response survey questionnaires, and collected data from 349 employees working at 9 hospitals and ambulatory clinics in Busan area. Frequency analysis, correlation analysis, factor analysis, and reliability analysis were performed using SPSS ver.18.0 program, and the path analysis was performed using AMOS ver.18.0 program. Major findings are as follows. First, some factors of pygmalion leadership were found to directly influence the quality of LMX, while some had both direct and indirect influences on organizational commitment. Second, the quality of LMX was found to partly mediate the relationship between pygmalion leadership and the organizational commitment in hospital organizations. This is the first in kind which was conducted in the hospital setting.

This study aimed to analyze the effects that the exchange relationship among employees engaged in the wedding industry in Busan, Ulsan and Gyeongnam area exerted on job satisfaction and voluntary service intentions. For this purpose, a theoretical model was presented based on previous studies and the relationship among variables was analyzed based on the analysis results through a survey. There have recently been great difficulties in the whole wedding industry due to the global economic depression and the low birthrate. Moreover, it is hard to optimize the future business environment. In particular, the low birthrate has weakened the demand base of the wedding industry. As a result, it is expected that the competition among companies will be more fierce in the wedding industry. Employees' voluntary service intention become much more important to overcome difficulties in this industry. Employees' voluntary service intentions can be possible when their job satisfaction is achieved. Many studies report the result that this job satisfaction can naturally be achieved when the high quality exchange relationship among a leader, team members (co-workers) and customers is formed. It is viewed that employees' voluntary service intentions should be induced through job satisfaction to improve the profitability through the efficient operation and management of the system. A leader of the organization should make an effort to form the high-quality exchange relationship with members, support so that team members(coworkers) and other employees can get along together and the teamwork can be improved and induce them to improve a high level of service quality with friendly customer services. In spite of the significance of the study discussed above, there are the following limitations in this study. There is a limit to a certain extent in generalizing study conclusions because the study was limited to the Busan, Ulsan and Gyeongnam area. If practical surveys which full- and part-time employees are included in the composition of samples are conducted for wedding suppliers in the country in the future, the quality of study will be able to improve.

The purpose of this study was to investigate the influence of techno-overload and techno-invasion on work-family conflict and the mediating role of psychological detachment from work to techno-overload and techno-invasion. In addition, this study examined the moderating role of leader-member exchange in the relationship between techno-overload, techno-invasion and psychological detachment from work. The results from 306 participants provided evidence that (1) techono-invasion was negatively related to psychological detachment from work, (2) psychological detachment from work was negatively related to work-family conflict, (3) psychological detachment from work partially mediated the relationship between techno-invasion and work-family conflict (4) leader-member exchange moderated the relationship between techno-invasion and psychological detachment from work. Based on the results, implications of these findings, limitations, and future research were dicussed in general discussion.

It is widely accepted that one of the main challenges of the 21st century welfare state is how to harmonize 'Old Welfare, Old Risks' which mostly consists of income maintenance programs with 'New Welfare, New Risks' which actively advances social services. It is in this regard that this paper attempts to define the relationship between the income maintenance programs and social services. For this purpose, it analyses social expenditure of 18 OECD countries during 1980-2006, and subsequently attests, if there is a trade-off relationship between the two, using correlation and Granger panel analysis. It duly concludes that the trade-off relationship between the two is not valid in that the two are better understood as a complementary relationship, not substitute relationship.

This study analyses the relationship between mothers and adolescent children in current Korean society from an exchange perspective. Utilizing the 6 types of resources, I. e., service, goods, money, information, status, and affection, suggested by Foa et. al. and the distinction between positive exchange (rewards) and negative exchange (punishments), it explores what resources are exchanged, how the resources exchanged are valued by each party, whether the exchange is symmetrical or asymmetrical, and if gender and age of the child affects the exchange. A survey was conducted to 150 children--from middle school aged to college going, and their cohabiting mothers in the metropolitan Seoul. The overall findings are as follows: Positive exchanges are dominant over negative exchanges. The exchange of positive exchanges occur asymmetrically within each resource type, with the exception of affection which is exchanged in a more equal term. In general, children receive positive resources more often, but mothers value the resources given by their children more highly. Negative resources are exchanged in more symmetrical terms. Negative resources exchanged more frequently tend to have weaker negative valence. Daughters maintain a more intensive exchange relation with their mothers than sons do, and this pattern is especially prominent in the exchanges of information and affection. The age of the child has a weak effect on the exchange.

We report an experimental evidence of coexistence of the strong and weak exchange couplings in unidirectional NiO/NiFe (antiferromagneticlferromagnetic) bilayer thin films. The exchange bias was measured by VSM and AMR techniques and then, analyzed into the strong and weak exchange couplings by means of a regression method. In NiO(60nm)/NiFe(10nm) film, the ratio of the weak exchange coupling field over the average exchange coupling field was found to be almost unchanged within it range from 0.2 to 0.4 irrespective to the strength of an applied field. However, the ratio increased among the samples with decreasing the average exchange coupling field due to the increment of the weak exchange coupling area.
