This current research investigated whether job stress mediates the relationship between physical environment and safety behavior of members in organization. Furthermore, we hypothesized that safety climate functions as moderator between physical environment-job stress link. In order to examine the hypotheses, 870 employees in various fields of companies were sampled. Using structural equation modeling(SEM), we conducted moderated mediation model analysis which cab elaborately test the significance of our hypotheses. The results showed that job stress mediated the link between physical environment and safety behavior of members. Moreover, the relationship between physical environment and job stress was moderated by safety climate. The implications and limitations of our study and suggestions for future research were discussed.

Purpose: This study was to determine the mediator or moderator role of empowerment in the relationship between the head nurse's transformational leadership and organizational commitment as perceived by staff nurses. Methods: Data was collected from 451 nurses in a tertiary hospital located in B city by means of structured questionnaires. Data was analyzed with descriptive statistics, Pearson's correlation coefficient and hierarchial multiple regression using the SPSS program. Results: Empowerment showed mediating effects between the head nurse's transformational leadership and organizational commitment as perceived by staff nurses. However, empowerment did not show moderating effects. Conclusion: Nurses' perception of empowerment, the head nurse's transformational leadership and organizational commitment have a strong relationship. This finding suggests the importance of empowering nurses to increase organizational commitment.

Graphite is suitable materials as a moderator, reflector, and supporter of a nuclear reactor because of high tolerance to the high temperature and neutron irradiations. Because graphite is so weak to the oxidation, its oxidation study is essentially demanded for the operation and design of the nuclear reactor. This work focuses on the effect of the surface oxidation of graphite according to the surface treatment. With thermogravimeter (TG), oxidation characteristics of the isotropic graphite are measured at the three temperature areas, and oxidation ratio and amounts are estimated as changing the surface roughness. Furthermore, the polished graphite surface produced fom the surface treatment is investigated with the Raman spectroscopic study. Oxidation behaviors of the surface are also evaluated as elimination the polished layer by washing with strong sonication.

The purpose of this study is to verify whether there is a difference in boredom between education types (offline vs. online) in the mandatory education scene, and to explore the moderator effect of meaning making activities in the relationship between education types and boredom. In this study, 197 college students were divided into offline and online groups and they participated in mandatory education. The meaning making activity was operationalized based on the meaning discovery scale. As a result of the study, the state boredom after mandatory education was significantly higher in the online group than in the offline group. However, meaning making activities did not moderate the relationship between education type and the state boredom. Through further analysis, it was found that boredom in both groups significantly decreased after the meaning making activity.

The current research examines whether and when cause marketing, whereby firms link product sales to the support of a charity or cause, can increase charitable giving and happiness. Previous research suggests that cause marketing might reduce charitable giving and happiness among consumers. However, the present research finds the opposite result by introducing nostalgia as a moderator; cause marketing can enhance consumers' charity giving when their nostalgia is triggered. Moreover, results show that charitable giving increased by cause marketing improves feelings of happiness, suggesting that people view charitable behavior as a means of enhancing happiness. Interestingly, charitable giving and happiness are promoted by the situational priming of nostalgic events, but not by chronic individual differences such as nostalgia proneness.

In today's highly competitive and fast changing business environment, key account management-a supplier company initiated relationship marketing approach targeted at the most important customers to solve their complex requirements with special treatment that eventually ensures both parties' financial and nonfinancial objectives- has regarded as a strategic weapon of many companies' sales efforts to manage their strategically important customers. On the basis of the existing studies, this research introduces a theoretical model highlighting the hypothetical relationship between key account management performance and repeat order. In addition, moderating effect of length of relationship on the relationship between key account management performance and repeat order is also introduced. We theorize the conditions under which key account management performance influences key customer repeat order behavior as well as the influence of moderating variable of length of relationship on key account management performance-repeat order relationship. Theoretical and managerial implications are provided along with suggestions to isolate a platform for future empirical research.

Background: This study evaluates physical function, balance, and cognition rehabilitation motivation. Design: Cross-sectional study. Methods: The subjects include 67 stroke patients to measure physical function, balance, and cognition rehabilitation motivation. For evaluation of physical function, Manual Muscle Test, Range of Motion, Modified Ashworth Scale for spasticity, grasping power, and balance was measured using Functional reach test (FRT), Berg Balance Scale (BBS). For evaluating Cognition, Korean-Mini Mental State Examination, motivation for rehabilitation scale was used to measure for motivation. Results: The results of this study that the moderating effect of rehabilitation motivation was significant in the effect of physical function on BBS (p<0.01), The moderating effect of rehabilitation motivation was significant in the effect of FRT on physical function (p<0.01), The moderating effect of external motivation was also significant in the effect of FRT on physical function (p<0.01). However, the results of the rehabilitation motivations generally divided into three groups (Lower, Average, Upper) and all three results were statistically significant only in groups of average and lower. Conclusion: This study confirms that the rehabilitation motive has demonstrated significant adjustment effects between the body function and balance. In this study, physical function, balance and cognition were significantly correlated with each other, and rehabilitation motivation proved a significant moderating effect between physical function and balance.
