This study focuses on the instructor's role in student-centered learning and aims to test the effects and moderating role of instructor feedback on perceived loafing in team project-based learning. A conditional effect model including team efficacy, perceived loafing, instructor feedback, and team performance was proposed. Data were collected from students who registered for team project-based learning courses at a university in South Korea. A total of 420 cases were subjected to moderated mediation analysis. The results demonstrated that instructor feedback was negatively related to perceived loafing and moderated the relationship between team efficacy and perceived loafing. Furthermore, instructor feedback moderated the relationship between perceived loafing and team performance. In particular, even when perceived loafing was high, students who received frequent instructor feedback were found to significantly reduce the damage to team performance. Based on these findings, the importance of instructors' facilitation in team project-based learning is discussed.

Purpose: Most of all studies regarding corporate social responsibility have been dealing with its direct performance. Many previous studies provided the evidence that corporate social responsibility activities directly affect firms' competitiveness or corporate reputation. However, there are no studies regarding the role of social capital between corporate social responsibility and firms' competitiveness. The present study aims to examine a mediating role of social capital between corporate social responsibility and corporate reputation. Research design, data and methodology: The structural equation model integrating corporate social responsibility, social capital, and corporate reputation was proposed with three hypotheses. Questionnaire including 15 question items for three concepts was designed. Data for testing hypotheses were collected from students and staff who had experienced the social responsibility activities of Korea Hydro & Nuclear Co. Ltd. SPSS and SmartPLS were used to analyze data. Results: All three hypotheses were supported at the significance level of 0.01. Corporate social responsibility have a significant influence on social capital as well as corporate reputation. Social capital plays a mediating role in the relationship between corporate social responsibility and corporate reputation. Conclusions: The present paper identified a missing link between corporate social responsibility and corporate reputation by validating an indirect effect of corporate social responsibility on corporate reputation through social capital. The present study contributes to finding the indirect link between corporate social responsibility and corporate reputation. Implications for academics and practitioners. The research model can be extended to analyze the relationship between corporate social responsibility and its performance. The present study sheds light on identification of a new role of social capital. Managers of firms have the opportunity to recognize the fact that investment recovery of corporate social responsibility results from social capital and corporate reputation in long-term rather than short-term. The results of this study offers an insight that managers can enhance customer loyalty. The process linking corporate social responsibility to corporate reputation through social capital implies that firms can realize spiritual marketing delivering authentic storytelling through corporate social responsibility. The present study has a limitation for generalizing of research results because the sampling came from a case of firm.

Purpose: This study aimed to clarify the relationship between analysis of rape myths acceptance and gender role stereotype among university students. Method: First-year students at two three-year colleges in Jeonnam and two three-year colleges in Jeonbuk (n=406) were selected by convenience sampling. Of these, responses from 386 (95.8%) were analyzed. Result: Rape myths acceptance in male students was significantly higher than female students (t=5.400, p=.00). In terms of gender role stereotype, male students were significantly higher than female students (t=3.869, p<.001). The relationship between rape myths acceptance and gender role stereotype was in the middle range of correlation: male students' correlation coefficient was r=.520 (=p<.001), and female students' was r=.524 (p=<.001). Conclusion: The results indicate that university students' attitudes toward sex have not been properly established yet. Moreover, they highlight that in our society there still exists a male dominated social structure and inequality of sexes. To prevent sexual violation from occurring at the universities, it is necessary that programs to establish proper attitudes of students toward these two factors, should be developed and the results monitored frequently. In addition, cross sectional studies aimed at understanding rape myths acceptance and gender role stereotypes are needed.

Purpose: Organizational justice is not considered as objective variable, but considerably, it is the employee's perceptions about an organization. Since the last four decades, researchers endorsed the significant importance of organizational justice on motivation and work behaviours like turnover intentions, trust, motivation, organizational commitment, job satisfaction, in-role and organizational citizenship behaviour. Accordingly, scant literature is available on procedural justice - organizational citizenship behaviour via mediating role of leader-member exchange (LMX) in higher education context especially in Asian countries like Pakistan. Research Design, Data and Methodology: Cross - sectional study design was used and data was collected from the 452 permanent and contractual teaching faculty serving in different positions at private and public sector degree awarding institutes / universities accredited by Higher Education Commission (HEC) of Pakistan. Mediated regression analysis, as proposed by Baron and Kenny (1986), was employed to address the research hypothesis. Results: Results showed that procedural justice and LMX was positively impacted on OCB and LMX also fully mediates the relationship of procedural justice and organizational citizenship behaviour (OCB). Conclusion: The result indicated that LMX fully mediates the relationship of procedural justice and organizational citizenship behaviour.

Magnesium (Mg) plays an essential role in physiological and metabolic reactions. Recently, there has been an increased interest in the role of Mg deficiency, particularly the relationship between serum Mg value and inflammatory response. This study was designed to determine the relationship between serum Mg deficiency with inflammatory response, electrolytes and hematological alteration over long-term periods. Sixteen male Sprague-Dawley rats were divided into two groups: control (n=8), and Mg deficiency group (MgD group, n=8). Chow and normal water (tap water) were regularly provided to the control group and Mg-depleted chow and third distilled water were regularly provided for 60 days to the MgD group. Body weights, Serum Mg, $K^+$, inorganic phosphorus (IP) and total iron binding capacity (TIBC) levels in the MgD group were lower than those of the control group (P<0.05). Granulocyte fraction and MCV, RDW and PDW levels were higher, whereas lymphocyte fraction, erythrocyte, hemoglobin and MCHC levels were lower in the MgD group than in the control group (P<0.05). MCP-1 and TNF-${\alpha}$ levels in the MgD group were greater than those of the control group (P<0.05). In conclusion, the results of the present study suggest that Mg deficiency over a long-term period had not altered total leukocyte concentration in the blood, but had detrimental effects, including disturbances of electrolytes balance, disturbance of iron indices, potential anemia and elevation of pro-inflammatory cytokine. However, further studies should be performed to determine the relationship between serum Mg deficiency and major organ damage or alteration.

There are many studies which reveal most of the accidents are related to pilot errors. Looking at each phase of flight, the accidents which occurred at the segments of take-off and landing consist of 70%, cause these phases need precise cooperations between pilots and ATC specialists to make sure every instructions understood and instruments to be normal. Therefore, the accidents of these phases leave great regrets and the price was enormous to people and equipments. Until now, most of the studies investigate the accident itself and very few show the relationships between pilots and air traffic controllers. This study analyzes the impacts of inter-dependence to mutual trust, cooperations and relationship efficiency between them who play important parts in flight. Based upon the findings, the inter-dependence has an effect on mutual trust and the latter influences to cooperations. Also, mutual trust and cooperations have a leading role in the relationship efficiency. It implies that mutual trust, cooperations, and the degree of inter-dependence are important factors to improve the relationships between them.
