Mediating Effect of Coping Behavior on the Relationship between Driving Stress and Traffic Accident Risk
초록보기
Abstract

The present study was conducted to determine the effects of driving stress on traffic accident risk. Specifically, this study verified the effects of driving stress on drivers' coping behaviors and the aptitude of mediating models through which coping behavior types affect traffic accident risk. As a result, driving stress directly increased traffic accident risk and indirectly affected them through(good and bad) coping behavior types. This indicates that driving stress directly and indirectly affect traffic accident risk by the medium of(good and bad) coping behavior types in multilateral ways.(Commercial and leisure-purposed) driving purposes showed significant differences in the relations between driving stress and traffic accident risk. Specifically, commercial drivers were affected by driving stress, compared to leisure-purposed drivers. As they were unable to defer or abandon driving even under driving stress, commercial drivers responded to the stress more sensitively and increased traffic accident risk by selecting inappropriate(bad) coping behaviors. The results show that the mere concentration on driving stress management cannot sufficiently lower the traffic accident risks caused by driving stress. This is because driving stress have indirect influences on traffic accident risk. Hence, it will be necessary to seek how to reduce driving stress and control coping behavior types in order to lower the traffic accidents risk by the stress.

초록보기
Abstract

This study were preformed for two purposes. The first is to develop a Korean vocational interest inventory based on Holland theory(short version) and second is to investigate of Holland's hypotheses(circular order and circumplex). With a sample of 149 high school students(male 58, female 91) and 224 college students(male 132, female 92), the main results were as follows. First, the scale which developed as 72 items in this study has shown acceptable reliabilities and construct validities, that is, this short form interest inventory could be used to verify student's vocational interest in conjunction with existing inventories. Second, the radnomization test using RANDALL(Tracey, 1997) has shown that the circular order hypothesis were supported. Third, in the results of confirmatory factor analysis, the modle that Holland's circumplex hypothesis was not adapted, has had better fit(TLI, RMSEA) than the model which Holland's circumplex hypothesis was adapted. Forth, the results of MDS showed the RIASEC interest types could be explained well through Sociaility and Confirmity of Hogan(1983). In summary, Holland's circular order hypothesis was supported but the circumplex hypothesis was not supported to Korean student's data. Finally, the implications and limitations were discussed.

Abstract

The purpose of this present study was to investigate the influence of LMXSC(Leader-Member exchange social comparison) on organizational commitment and deviant behavior in workplace. It was also tested whether perceived leader status moderates the relationship between LMXSC and organizational commitment and deviant behavior. Data were collected from 306 employees who were working in various organizations. The results showed that (a) LMXSC was positively related to the organizational commitment, (b) perceived leader status moderated the relationship between LMXSC and organizational commitment. The relationship between LMXSC and deviant behavior was, however, not significant. Moderating effect of perceived leader status on relationship between LMXSC and deviant behavior was not significant, either. Based on these results, implications of these findings, limitations and future study directions were discussed.

Abstract

The purpose of this study is to identify the relationship between leader’s communication style and the members’ organizational commitment focusing on the mediating and moderating factors. Specifically, we considered trust as the mediator of the relationship between communication style and organizational commitment. Also, the perception of leader’s ability was considered as the moderator of the relationship between communication style and trust of the leader. Survey results on the 350 officers in the Korean Army show that the leader’s communication style was significantly influencing on the organizational commitment of the men under his(her) command. Specifically, sociable communication style had positive effects on the level of organizational commitment, whereas dominant style influenced negatively. Also, the relationship between leader’s communication style and organizational commitment has been partially mediated by trust of the leader. Finally, the perception of leader’s ability has moderated the relationship between leader’s communication style and trust of the leader, such that the negative effect of dominant communication style on the trust level has been strengthened when their leader's ability is low than high. Comparably, the positive effect of sociable communication style on the trust level has been strengthened when the perception of leader’s ability is high than low. The implications and limitations of those empirical results was discussed.

초록보기
Abstract

This study examined the relationships between organizational context and the chief executive officer (CEO)’s psychological statements. To this end, using a linguistic analysis program of K-LIWC, content analyses were conducted on three major speeches-the New Year’s addresses, the founding day addresses, and the year-ending farewell Address-which had been presented between 1969 and 1992 by the founder and chief executive officer of POSCO. This study analyzed two kinds of organizational context; the number of critical events within and outside the organization and the three stages of organizational development. With respect to the number of critical events measured as one aspect of organizational context, it was found that the greater the number of critical events, the more the CEO used words with both positive emotion and negative emotion. In relations to the organizational development stage measured as another aspect of organizational context, psychological statements related to both emotional and social processes were made significantly more often during the entrepreneurial stage and growth stage compared to the expansion stage. The findings suggest that the outstanding CEO tend to adjust the use of psychological words according to the change in organizational context in communicating with organization members through speeches. Finally, the theoretical and practical implications and limitations of the current study were discussed.

Abstract

This study were preformed for verifying the applicability of Assessment Center(AC) for selection of university student. First, the results of decision study of generalizability theory(D study) has shown acceptable reliabilities. So, we could think that this AC was designed properly. Second, the enrolled students of the university have said that the competencies rated in this AC were important for performing study and adapting to school. And participants in this AC reported they have felt fairness and they could have done their best. It means that this AC had validity. Third, generalizability study(G study) has shown dimension effect(21.1%) was higher than rator effect(10.2%). And, in the MTMM analysis, it were found both dimension effect and exercise effect. Forth, in relation analysis between AC ratings and the various records of participants, ‘Self-led Study’ related with ‘Records of Language’ positively, ‘Discussion Skill’ related with ‘Public Anxiety’ negatively, ‘Challenge’ related with ‘Extraversion, Self Efficacy, and Record of Award off campus’ positively and with ‘Anxiety to unfamiliar’ negatively, ‘Creativity’ related with ‘Extraversion’ positively, ‘Adapting to Change’ related with ‘Emotional Stability’ positively, and ‘Interpersonal Competencies’ related with ‘Performance Anxiety and Public Anxiety’ negatively. In short, this AC has shown applicability as selection tool for university student. Finally, the implications and limitations were discussed.

Abstract

The purpose of the present study was to examine whether work overload and unreasonable organizational climate have significant relationship with emotional exhaustion. The present study also attempted to find out whether psychological detachment has mediating effects on the relationship. Psychological detachment refers to an individual's experience of being mentally away from work, to make a pause in thinking about work-related issues, thus to “switch off”. Previous research has suggested that psychological detachment from work during off-job time is important in order to recover from stress encountered at the job. Data were collected from 234 workers employed in a variety of organizations. It was found that work overload and unreasonable organizational climate were significantly associated with low psychological detachment and high emotional exhaustion. In addition, psychological detachment had mediating effects on the relationship of work overload and unreasonable organizational climate to emotional exhaustion.
