Leader-Member Exchange (LMX) model of leadership has suggested that members within the same work team are differentiated in terms of their level of the quality of leader member relationships. However, the differentiation in leader member relationships has not been examined for its possible team-level effects. In this study, the possible impact of this role differentiation on team members' affective reactions was explored. As hypothesized, teams whose members experienced higher level of LMX tended to have higher overall job satisfaction, organizational commitment, and team efficacy. Contrary to expectation, however, the team-level mean on LMX was not related with team-level variability on LMX. Based on these findings, several theoretical and practical Implications are discussed.

The study aims to verify the relationship between leaders' personality traits in leader - member exchange (LMX), and job performance. Hierarchical Regression Analysis was used to examines (a) how leaders' personality traits and LMX affect the influence of social capital on job performance and organizational citizenship behavior; (b) how perceived organization support (POS) can moderate the influences of LMX on social capital, in turn impacting job performance and OCB. Responses are employees in the service industry in Thailand, which consisted of 236 independent samples in 77 groups. Each group included at least one leader and 1-5 followers. The results show that there is a significant relationship between leader's personality traits, LMX and social capital. Leader with the higher level of conscientious, and agreeableness can always create good relations with their followers. The level of LMX are also related to social capital and both of these influence OCB and job performance. The moderating effect of perceived organizational support is also significant that POS can amplify the influence of LMX on social capital. Finally, the research findings show that perceived organizational support is one of the moderating factors in LMX exchanges. Followers perceived organizational support can amplify the influence of LMX on social capital.

Objectives:This study aimed to identify the influences of leader-member exchange (LMX) and psychological empowerment of the dental hygienists on their job satisfaction. Methods: A self-administrated questionnaire survey was conducted from July 7 to August 2014 targeting 196 dental hygienists in Busan and Gyeongsangnamdo. Leader-member relationship, psychological empowerment and job satisfaction were evaluated by LMX scale, psychological empowerment scale and job descriptive index (JDI), respectively. Data were analyzed by descriptive analysis, t-test, one-way ANOVA, and multiple Linear regression analysis. Results: Overall LMX, psychological empowerment on job satisfaction level of subjects were $3.43{\pm}0.61$, $3.38{\pm}0.66$ and $3.20{\pm}0.42$, respectively. The influential factors of LMX, psychological empowerment and job satisfaction were professional respect (subcategory of LMX), affect (subcategory of LMX), meaning (subcategory of psychological empowerment) and impact (subcategory of psychological empowerment). Conclusions: Job satisfaction of dental hygienist is closely related to professional respect, affect, meaning and impact.

본 연구는 지각된 팀효능감의 선행변인으로서 LMX의 역할과 결과변인인 조직시민행동과의 관계를 규명함과 동시에 지각된 팀효능감의 매개효과와 리더 도덕성의 조절효과를 검증하였다. 연구결과, 첫째, 높은 수준의 LMX는 구성원들이 지각하는 팀효능감에 통계적으로 유의미한 긍정적인 영향을 주었다. 둘째, 구성원들이 팀효능감을 높게 지각할수록 개인지향(OCBI) 및 조직지향(OCBO) 조직시민행동에 긍정적인 영향을 주었다. 셋째, 지각된 팀효능감은 LMX와 OCBI의 관계에서는 완전매개역할을, LMX와 OCBO의 관계에서는 부분매개역할을 수행하였다. 마지막으로 리더 도덕성은 LMX와 조직시민행동(OCBI, OCBO) 모두에서 리더도덕성이 높은 집단이 그렇지 않은 집단에 비해 더욱 높게 나타났다. 마지막으로 토의 및 결론을 통해, 본 연구의 시사점과 한계점 및 향후 연구방향을 제시하였다.

The objectives of the study were to investigate job burnout and leader-member exchange (LMX) levels as well as to evaluate buffering effects of LMX on burnout among dietitians and chefs at institutional foodservices. Hypotheses were proposed based on the Job Demands-Resources model and LMX theory. The study population consisted of dietitians and chefs who were in charge of managing unit operations in a nationwide contract management company. Positive/negative affectivity, workload, job burnout, and LMX scales that bad been validated in previous research were adopted A total of 552 questionnaires were distributed and 154 responses were returned. Results indicated that respondents' burnout levels were moderate and emotional exhaustion was greater than cynicism. In terms of LMX, the surveyed dietitians and chefs showed higher respect toward their supervisors than loyalty. When positive affectivity and negative affectivity were controlled, workload influenced emotional exhaustion and professional efficacy significantly. With affectivity and workload controlled, however, LMX did not influence any dimensions of burnout. The moderating effect of LMX on the relationship between workload and cynicism was significant. That is, the effect of workload on cynicism was weak if the dietitians and chefs perceived the relationship with their supervisor positively. Based on the findings and literature reviewed, how to mitigate job burnout among foodservice managers is discussed.

본 연구는 조직시민행동의 선행요인을 찾고, 그리고 LMX(leader-member exchange)의 매개역할을 살펴보는 것이다. 선행연구 검토를 통해 본 연구는 조직시민행동과 LMX에 영향을 미치는 요인을 개인(분배, 절차 공정성), 그룹(변혁적 리더십, 팀 임파워먼트), 그리고 조직(조직구조의 복잡성)수준으로 분류하였다. 산업단지 공단에 근무하는 종업원들을 대상으로 설문조사를 실시하였고, 총 773부의 설문지가 실증분석에 사용되었다. 실증분석 결과, 절차적 공정성, 변혁적 리더십, 그리고 팀 임파워먼트가 조직시민행동에 정(+)의 영향을 미치는 것으로 나타났다. 또한 분배공정성, 절차공정성, 변혁적 리더십, 팀 임파워먼트, 조직구조의 복잡성은 LMX에 정(+)의 영향을 미치는 것으로 나타났다. 게다가 LMX는 5개의 독립변수(분배공정성, 절차공정성, 변혁적 리더십, 팀 임파워먼트, 조직구조의 복잡성)가 조직시민행동에 미치는 영향관계에서 매개역할을 하는 것으로 나타났다. 연구결과를 바탕으로 연구의 시사점과 한계점 등에 대해서도 논의하였다.

Objectives: This study proposes a hypothetical model for job stress, job satisfaction, organizational commitment, and turnover intention through social exchange relations (LMX, TMX) and political skills (LPS) for dental hygienists working in dental clinics hygienists. Methods: A self-administrated questionnaire was administered from April 1 to May 12, 2020, with 171 dental clinic hygienists participating in Seoul, Busan and Gyeongnam. The data were analyzed using SPSS and AMOS statistical analysis programs. Results: First, in the hypotheses testing, a total of 7 of 18 hypotheses were supported. Second, the relatonship between leader-member exchange (LMX) or team-member exchange (TMX) and turnover intention, a full mediating effect of job stress or job satisfaction or organizational commitment on that exchange was found. However, the leader's political skills on the path to turnover intention were not statistically significant. Conclusions: It is considered that education to enhance job skills, support for leisure activities, and time to communicate opinions with each other should be provided to create an organizational culture that satisfies all members, thereby lowering the intention to turnover.

Purpose - This study aims to measure the influence of the positive psychological capital (PPC) of business workers by using innovative work behavior (IWB) and the influence of Leader-member exchange (LMX) and Member-member exchange (MMX) in this relation and investigating the directional efforts of small and medium company leaders and members. Research Design, Data, and Methodology - This study selects PPC as an integrated superior concept to establish research models and hypotheses of the influence of PPC on IWB, and the influence of LMX and MMX in these relations. Of the questionnaires distributed, 373 valid questionnaires were collected in total. Results - It was confirmed that the PPC of workers has a statistically significant influence on LMX, MMX, and IWB. Moreover, LMX and MMX have similar influence on worker life satisfaction with life satisfaction and innovative work behavior having different dimensions. Conclusion - To enhance IWB, worker PPC is very important as it has significant influence on the relations with leaders. However, it is also notable that positive relations with colleagues did not influence IWB.
