In this study, I focus on analyzing how the effects of implementing ETS are different depending on whether Korean ETS linking with carbon markets in other countries. The global computable general equilibrium (CGE) model built in this study analyzes the chages in the production and trade of industrial sectors according to the international linkage of ETS compared to the reference scenario of emissions reduction targets and implementation of ETS. From the analysis of internatioanl linkage of carbon markets scenarios, Annex B countries-South Korea carbon market linkage with individual ETS in China worse the economic outcomes in South Korea the most. This means South Korea lose the international competitiveness compared to China in this scenario. On the other hand, Annex B-China carbon market linkage with Korean individual ETS implementation reduce the decreases in production and trading. The most effective way is to join a global emissions trading market with China. The results are consistent in most industries of South Korea. These results are caused by that the supply of emission allowance is increased and the price of emissions allowances is dropped by China's participation to the carbon market, which can be understood to reduce the carbon reduction cost for industrial sectors. In addition, it can be also concluded that the determinant of the negative impact of ETS on changes in production and trade is more sensitive to the price of emissions allowances than to the characteristics of production and trade structure.

This paper aims at investigating voluntary user participation such as user citizenship behavior and aberrant user behavior in the SNS context. Also it examines on how user participation behavior affects social connectedness, privacy concern, and user satisfaction. The empirical assessment of the research model was conducted using a total of 143 responses. The findings show that user citizenship behavior impacts on social connectedness positively and significantly whereas aberrant user behavior does not influence on social connectedness. Aberrant user behavior is proven not to be related to social connectedness, and to has positive relationship with concern for privacy invasion. Also, the results show that privacy concern is not associated with social connectedness. Finally, social connectedness is shown to be a key determinant of SNS user satisfaction whereas privacy concern is not related to user satisfaction.

The purpose of this study was to provide basic materials needed to enhance quality of organizational life by identifying the improvements of labor union management in the perspective of general hospital organization management. The subject of this study were 686 employees in 12 General Hospitals in Metro Capital including Seoul. Materials were collected from administrators, nurses and medical technicians in target hospitals from March 20 to May 10, 2005 through survey questionnaires. The main results of this study were as follows: 1. the commitment level of the subjects according to their characteristics was higher in older employees than the younger ones, large family to support than small family to support and those who had higher positions in labor union. 2. The commitment level of the subjects according to the job and role related variables were higher those who had higher satisfaction level to their job and manager, role conflict in all hospitals. 3. The commitment level of the subjects according to union related variables, variables jointly controlled by union and employer was satistically significant positive correlation. In other words, the commitment level of the subjects according to the subjects' labor union involvement was higher in those who had higher satisfaction in labor union and perceived their colleagues' attitudes more positively in all hospitals. Regarding the atmosphere of the relationship between union and employer and the level of commitment in labor union, the better the atmosphere of the relationship between union and employer was, the higher the level of commitment in labor union was in all hospitals. 4. The results of multiple regression analysis shows that formal and informal socialization, union participation to the union management cooperation program, job satisfaction, satisfaction with the labor union's were all found as important antecedents of labor union commitment. 5. Job and role-related variables, union-related variables, variables jointly controlled by union and employer, and labor union commitment level were all found significantly different in accordance with the characteristics of unions concerned. To summarize study results, the level of commitment in labor union depends on job satisfaction, manager's attitudes, satisfaction to their jobs, union satisfaction, their colleagues attitudes toward union and the atmosphere of employer-employee relationship. Therefore hospital managers should have democratic and flexible attitudes toward labor union. Additionally, as formal and informal socialization, union participation to the union-management cooperation program is important determinant in union commitment, hospital managers should have countermeasures to enhance the colleague attitude and job satisfaction level of hospital employees. Since this study deals with psychological nature of workers not a few drawbacks and shortcomings may be detected in the finding. Nevertheless, the finding of this study, to become a momentum that will stimulate further research to detect all the cues of labor union commitment and to provide valuable reference in forming logical union commitment and labor union-management cooperation.

Objectives The purpose of this study was to evaluate psychological effects of an outbreak of Middle East respiratory syndrome (MERS), a newly emerged infectious disease, on doctors. Methods After the MERS outbreak was over, we conducted an online survey of doctors who worked at the hospitals in which exposure to MERS cases had been confirmed or who were directly involved in MERS diagnosis and treatment. The Patient Health Questionnaires-9 (PHQ-9) and the Impact of Event Scale-Revised (IES-R) assessment methods were used to assess the severity of depressive and posttraumatic stress symptoms among the 64 doctors participating in the survey. Results The results of the survey indicate that 26.6% (n=17) of participants exhibited depressive symptoms and 7.8% (n=5) had post-traumatic stress symptoms. The doctors employed at hospitals with MERS cases had higher PHQ-9 and IES-R mean scores than those in doctors were not so employed. In contrast, there was no significant difference in those test scores between doctors who participated directly in MERS diagnosis and treatment and those doctors who did not. Conclusion The survey demonstrated that 28.1% (n=18) of doctors involved in MERS care suffered from depressive or posttraumatic stress symptoms, even though the MERS infection was being controlled. Working at a hospital with MERS cases was the primary determinant of the adverse psychological outcomes among doctors ; however, direct participation in the diagnosis and care of MERS patients was not significantly related to such outcomes.

This study investigated teachers' decision-making and related factors in the elementary textbook adoption process. Our participants include 296 elementary teachers who took part in the mathematics textbook (grades 3 and 4) adoption committees in his/her schools. Our study used the decision-making model of Shavelson and Stern (1981) for analyzing teacher beliefs and attitudes concerning choices and priorities, judgments, evaluation methods, and key factors to reviewing and selecting a mathematics textbook. Our discussion includes teacher beliefs and intentions and the way they come into conflict with determinant factors that influence the decision-making of textbook adoption. Findings also reveal the unique nature of elementary school teaching as generalists in contrast with secondary teachers as specialists, playing a significant role in the adoption process. Lastly, the study discusses the entanglements of textbook reform and explains the discrepancy between textbook authorization/approval policies versus the plight of little change (and innovation) in mathematics textbooks.

The concept of sharing economy has received rich attention in recent years. As a typical type of business model in the sharing economy, online short rent has been paid attention by both industry and academia. In this study, we find trust to be a critical determinant to the success of online short rent platforms. Based on three dimensions of trust theory, i.e., ability, benevolence and integrity, we investigate the factors influencing tenant' willingness to participate in online short rent. We further examine the extent to which trust can influence the number of sales and comments of rooms listed at online short-term rent platforms, which can represent tenant' willingness to participate in the sharing economy. The results show that the trust dimensions represented by a landlord's personal characteristics have significant positive correlations with the number of sales and comments. For example, the real name authentication and the sesame score can represent the trust integrity; online replay ratio and the average confirmation time representing the trust sincerity, and the order acceptance ratio representing the trust ability. On this basis, we proposed some recommendations for both platforms and landlords. For example, the landlords can improve the tenants' trust by authenticating his/her real name, replying actively and timely. For platforms, when they make housing list ranking rules, they can take the landlord's personal attributes that may affect trust into consideration. Moreover, platforms can also allow landlords to supply value-added services to improve service quality and ultimately promote the virtuous circle of the platform ecosphere. Through conducting the empirical research on a particular application of the sharing economy, we aim to fill the research gap of this field in China and provide theoretical and practical contributions to the future development of online short rent.
