This study examined the effects of non - personality behavior of supervisors on the job exhaustion and organizational effectiveness of nurses. A survey in the form of a questionnaire was completed by 250 nurses working at three general hospitals located in Seoul and Gyeonggi from September 20 to October 31, 2014. The collected data were analyzed by frequency analysis, factor analysis, correlation, and linear regression analysis using the SPSS program. The results of the analysis were as follows. First, the effects of the non-personality behavior of supervisors on the job exhaustion of nurses were statistically significant. Second, the effects of non-personality behavior of supervisors on the organizational effectiveness of nurses were statistically significant in job satisfaction, organizational commitment, and organizational citizenship behavior. Third, the effects of job exhaustion on organizational effectiveness of nurses was statistically significant for job satisfaction, job exhaustion, and organizational citizenship behavior. Because the non-personality behavior of a supervisor can have a negative effect on the exhaustion of a nurse's job and the organizational effectiveness, there should be a wide range of human resources and effective task allocations in a hospital to reduce job burnout and increase job satisfaction. In addition, it is necessary for the boss to develop desirable leadership education, appropriate modeling, and reduce their negative influence in the workplace.

The purpose of this study is to examine the moderating effect of conflict in the relationship between neuroticism and abusive supervision. In previous studies, neuroticism was considered to be an important predictor of abusive supervision. According to the research results, supervisors with high neuroticism are more likely to be abusive supervision. However, in some studies, there was no significant relationship between neuroticism and abusive supervision. Therefore, this study considered conflict as a environmental factor in the relationship between neuroticism and abusive supervision based on the Trait Activation Theory. The higher the level of conflict, the more likely it would be that there would be a positive relationship between neuroticism and abusive supervision, and a lower level of conflict would not have a significant relationship between neuroticism and abusive supervision. Therefore, this study hypothesized the moderating effects of conflict in the relationship between neuroticism and abusive supervision. In order to test this hypothesis, this study conducted a questionnaire survey on the employees who work in South Korea. The implications and limitations of the study and the direction of future research are presented in the conclusion.

Until now most of the leadership studies have been focused to managers having in formal authority. However, in the recent business environment, team member should also demonstrate his leadership. Hence, the purpose of this study has been focused to the team member's leadership and their leadership effectiveness. In this study, we verified how the degree of master sergeant's support can control to moderate the intensity of the team member's leadership behavior. The analysis results were as follows: we have found that team member's issue leadership can effect on positive(+) way on the audience's acceptance to the leader as well as team performance. But the moderating effects of master sergeant's support on the team member's issue leadership and leader acceptance was not significant in terms of statistical point of view. It has also shown even the negative(-) effects of master sergeants's support on the team member's issue leadership and leader acceptance as well as team performance. Through this study, we can understand that the master sergeant's support may impeding the team member's independent leadership.

A methodology of design performance estimation for the supersonic impulse turbine was investigated. Relations of similarity condition and test nozzle area ratio were derived. Comparison of efficiencies between the turbines with real nozzle and test nozzle are made numerically and experimentally. The CFD results and test result confirmed that the turbine with test nozzle was able to predict real turbine performance. In addition, design performance of the supersonic impulse turbine also could be estimated using real nozzle in air-medium test. In this case, design efficiency was found at the pressure-ratio and velocity-ratio of similarity condition of test nozzle.

The purpose of this study is to empirically analyze the effects of characteristics of Leader (authoritarian disposition, procedural justice, job instability) on the organizational commitment of subordinates through abusive supervision and leader-member exchange(LMX). To this end, a survey was performed on the employees under the manager level in a large enterprise in Korea. The results of this study are as follows. First, the Hypothesis 1, 2, and 3 that the characteristics of leader (authoritarian disposition, procedural justice, job instability) will make effects on the organizational commitment of subordinates through abusive supervision were adopted. Second, in the hypotheses that the characteristics of leader (authoritarian disposition, procedural justice, job instability) will make effects on the organizational commitment of subordinates through LMX, Hypothesis 4 of authoritarian disposition, and Hypothesis 6 of job instability were rejected, while only Hypothesis 5 of procedural justice was adopted, as it made effects on the organizational commitment of subordinates through LMX. Third, the Hypothesis 7, 8, and 9 that the characteristics of leader (authoritarian disposition, procedural justice, job instability) will make effects on the organizational commitment of subordinates through abusive supervision and LMX were all adopted. This study is meaningful, in that it identified the structural relationship that the characteristics of leader make effects on the organizational commitment of subordinates through abusive supervision and LMX. It is expected that the results of this study can be used as base materials for new studies on abusive supervision which have been made in diversified ways in Korea and overseas.

The purpose of this present study was to investigate the influence of abusive supervision on strain-based work interference with family and interpersonal deviance. In addition, this study examined the mediating effect of subordinates' emotional labor toward supervisors and the moderating effect of hierarchical organizational climates on emotional labor, perceived organizational family support on strain-based work-family conflict, and social network on interpersonal deviance. The results are summarized as follows: (1) abusive supervision was positively related to subordinates' emotional labor toward supervisors. (2) Emotional labor was positively related to strain-based work-family conflict and interpersonal deviance. (3) Subordinates' emotional labor mediated the relationship between abusive supervision and the two outcome variables. (4) Hierarchical organizational climates moderated the relationship between abusive supervision and emotional labor. (5) Perceived organizational family did not have moderating effect between emotional labor and strain-based work-family conflict. (6) Social network had moderating effect but it did not influence interpersonal deviance as predicted by the hypothesis. Based on the results, implications of findings, limitations, and suggestions for future research were discussed.

There is an increasing awareness about the abusive supervision(AS) and organizational silence(OS) in organizations and literature about the relation between organizational commitment(OC). But there is a shortage of studies about the abusive supervision and organizational silence in travel service. The purpose of this study is to research reasons of abuse supervision in organizations, its effects, results and applications which can minimize or remove abusive supervision by discussion. In this sense, Questionnaires were delivered 9 travel agencies in Seoul and 241 of them were taken. Questionnaire data was analyzed, and according to the results, some implications were proposed. Abusive supervision affects on organizational silence and organizational commitment of employee in travel agent. Organizational silence ha positive effects on organizational commitment. Organizational silence plays as a role of mediator variable in proposal research model. It is hoped that the present research will encourage future multi-level theoretical and empirical work on abusive supervision.

Although there are several experimental techniques to evaluate the seismic behavior and performance of civil structures, small-scale models in mast of physical tests, instead of prototypes or large-scale models, would be used due to a limitation on capacities of testing equipments. However, the inelastic seismic response prediction of small-scale models has some discrepancies inherently because the similitude law is generally derived in the elastic range. Thus, a special attention is required to regard the seismic behavior of small-scale models as one of prototypes. In this paper, differences between prototypes and small-scale models pseudodynamically tested on steel column specimens are investigated and an alternative to minimize them is suggested. In general, small-scale models could have the distorted stiffness induced from some experimental errors on test setup, steel fabrication and so on. Therefore, a modified similitude law considering both a scale factor for length and a stiffness ratio of small-scale model to prototype is proposed. Using the modified similitude law to compensate experimental errors, the pseudodynamic test results from modified small-scale model are much improved as compared with the results of prototype. According to the pseudodynamic test results of small-scale steel models, it can be concluded that the modified similitude law proposed could be effective in simulating the seismic response of prototype structures.

The flight control law of developed flight control computer(DFLCC) is developed based on operation flight program of advanced trainer aircraft full scale development final configuration. The flight control law design is used common use development tool in GUI(Graphic User Interface) environment. The flight control law transformed to C-Code is reflected in OFP. The OFP is verified by the standardized verification process. But, before standardized verification process, we need preliminary verification process such as similarity of flight control law and reliability of developed HILS. Similarity of flight control law is verified by comparing the aircraft response of advanced trainer aircraft and those of the developed control law. Also, reliability of developed HILS is verified by comparing the aircraft response of HILS and Non-real time simulation result. This paper verifies similarity of developed control law and reliability of HILS environment as comparing aircraft response.
