Greenberg(1990) suggested that organizational justice research may potentially explain many organizational behavior outcome variables. One example of nontraditional job behavior is service quality, for it is part of the spontaneous and innovative behaviors noted by Katz(1964). The first purpose of this research is to test the effects of organizational justice on service quality, and the second purpose is to test the moderating effects of sex and tenure on the relationships between organizational justice and service quality According to statistical analysis, only interactional justice had an impact on service quality. Also the results of moderating regression analysis showed that short term employees were more sensitive to distributive justice than long term employees. This result means short term employees are more interested In incentive system than long term employees.

Forecasting exchange rate movements is a challenging task since exchange rates impact world economy and determine value of international investments. In particular, Korean-U.S. exchange rate behavior is very important because of strong Korean and U.S. trading relationship. Neural networks models have been used for short-term prediction of exchange rate movements. Least squares support vector machine (LS-SVM) is used widely in real-world regression tasks. This paper describes the use of LS-SVM for short-term and long-term prediction of Korean-U.S. exchange rate.

The purpose of this study is to investigate relational benefits affecting the relationship quality and the existence of differences to which relational benefits are most important to the customers across the type of services that customer buys and customer's relationship orientation in how they orientate their relationships with service firms. The results of this study are summarized as follows: First, all relational benefits, economic, social, psychological, functional benefits, is related the relationship quality. Second, There is a difference in the perceived relative importance of relational benefits that customers will lead to the establishment of a long-term relationship across the type of service. The more service is customized, the less economic benefits affect relationship quality and the more psychological benefits affect relationship quality. however there isn't a difference in the effect of functional benefits on relationship quality across the types of service, functional benefits are a important benefits both situations. Third, There is a difference in the perceived relative importance of relational benefits that customer will lead to the establishment of a long-term relationship across customers. The more customers orientate their relationships with service firms, the more psychological benefits affect relationship quality. The less customers orientate their relationships with service firms, the more economic and functional benefits affect relationship quality. However there isn't a difference in the effect of social benefits on relationship quality across customers. In addition to, relationship orientation is related to demographic facets such as sex-type, age and income. Male is higher relationship orientation than female. The more customers are older, the more they orientate their relationships with service firms and the more customers have income, the more they orientate their relationships with service firms.

The purpose of this study was to examine the relationship among potential job-related risks, emotional dissonance, and job turnover intention of caregivers at the long-term care facilities in South Korea, and to explore the potential mediator role of burnout in this association. For the study, survey data of 434 caregivers at long-term care facilities were collected and analyzed using structural equation modeling method. The results showed that high level of caregivers'perception of the potential job-related risks led to increased burnout and turnover intention of caregivers. Second, caregivers'burnout partially mediated the effect of the potential job-related risks on turnover intention. Third, the more caregivers experience emotional dissonance, the higher the possibility of caregivers'burnout. On the other hand, emotional dissonance of caregivers did not give significant direct impact on turnover intention. Burnout fully mediated the relationship between emotional dissonance and turnover intention of caregivers. Lastly, the more caregivers experience burnout, the higher possibility of turnover intention. Based on the results, researchers suggested possible intervention methods as well as preventive measures to reduce the turnover of caregivers at long-term care facilities.

Purpose: To investigate the surgical, perfusion, and molecular characteristics of glioblastomas which influence long-term survival after treatment, and to explore the association between MR perfusion parameters and the presence of MGMT methylation and 1p/19q deletions. Materials and Methods: This retrospective study was approved by our institutional review board. A total 43 patients were included, all with pathologic diagnosis of glioblastoma with known MGMT methylation and 1p/19q deletion statuses. We divided these patients into long-term (${\geq}60\;months$, n = 7) and short-term (< 60 months, n = 36) survivors, then compared surgical extent, molecular status, and rCBV parameters between the two groups using Fisher's exact test or Mann-Whitney test. The rCBV parameters were analyzed according to the presence of MGMT methylation and 1p/19q deletions. We investigated the relationship between the mean rCBV and overall survival using linear correlation. Multivariable linear regression was performed in order to find the variables related to overall survival. Results: Long-term survivors (100% [7 of 7]) demonstrated a greater percentage of gross total or near total resection than short-term survivors (54.5% [18 of 33]). A higher prevalence of 1p/19q deletions was also noted among the long-term survivors (42.9% [3 of 7]) than the short-term survivors (0.0% [0 of 36]). The rCBV parameters did not differ between the long-term and short-term survivors. The rCBV values were marginally lower in patients with MGMT methylation and 1p/19q deletions. Despite no correlation found between overall survival and rCBV in the whole group, the short-term survivor group showed negative correlation ($R^2=0.181$, P = 0.025). Multivariable linear regression revealed that surgical extent and 1p/19q deletions, but not rCBV values, were associated with prolonged overall survival. Conclusion: While preoperative rCBV and 1p/19q deletion status are related to each other, only surgical extent and the presence of 1p/19q deletion in GBM patients may predict long-term survival.

This study investigated the relationship between economic growth and energy security risk levels in Korea using linear and non-linear ARDL methods. While there are many studies on the relationship between energy consumption and economic growth, few studies focus on the relationship between energy security and economic growth considering 4A dimensions of energy security such as energy availability, accessibility, acceptability, and affordability. Energy risk index from Global Energy Institue and GDP data from world bank are used for ARDL and NARDL analysis. Our result of ARDL shows that there is no long-term relationship between energy security risk levels and economic growth. On the other hand, NARDL result shows that there is an asymmetric relationship between economic growth and energy security risk levels in the long run. The results show the importance of expending further research on ensuring energy security to policymakers.
