Purpose - This study has its purpose to identify the correlation between factors and moderating variables that can reduce job burnout by setting a positive relationship with a leader and ethicality of the leader as factors reducing job burnout and helping behavior as a moderating variable. Research design, data, and methodology - The research design would make theoretical perceived ethical leadership and LMX toward helping assistance, and job burnout using by structural equation method. Results - As a result, both positive behaviors and recognition on ethical leadership of a leader have been confirmed to influence on mitigation of job burnout. Especially, among the two factors, ethicality has shown to be more efficient to alleviate exhaust compared with positive behavior of a leader. Conclusions - Theoretical perceived ethical leadership and LMX toward a leader, helping assistance, and job burnout are statistically significant, however, the helping behavior of members is the factor increasing a job burnout. These results can be interpreted as the difficulties of relation setting with the members for the leader, and although loyalty and responsibility toward right leader may induce helping behavior, and positive behavior for organization can impact on the job burnout. It can be concluded that the ethicality of a leader is an essential factor for the development of organization.

This paper proposes controller of leader robot considering following robot with input constraints based on leader-following approach. In the previous formation control researches, it was assumed that leader and follower is same object. If leader robot drives as maximum speed that the initial position errors still remain even if following robot have same velocity as a leader. In the situation that velocity of following robot is lower than its leader robot, following robot cannot follow leader robot. Furthermore, the following robot will not be able to made formation with leader robot and keep proximity communication or sensing range. Therefore, multiple mobile robot system using leader-following method should be guaranteed range to get information each other. In this paper, Leader robot is driving to goal position using linear controller and following robot is following trajectory to be made from leader robot. We assume that following robot has input constraints to realize different performance between leader robot and following robot. We design controller of leader robot for desired goal position including the errors between formation and following robot. Thus, we propose leader robot controller considering input constraints of following robot. Finally, we were able to confirm the validity of the proposed method based on simulation results.

This study analyzed the effects of fashion companies' organizational types on job satisfaction and organization commitment of fashion designer. As well as this study analyzed the differences the organizational types, job satisfaction and organization commitment by the gender and age of fashion designer. A survey was conducted from January 5 to 30 in 2015, among fashion companies' designer of Seoul metropolitan area. And 238 responses were used in the data analysis. As a result, fashion companies' organizational types was composed of five factors(coordinating leader organization, group creative organization, external innovators' collaborative organization, bureaucratic hierarchy organization, integrative thinking leader organization). Job satisfaction of fashion designer was composed of three factors(work satisfaction, employment satisfaction, relationship satisfaction), and organization commitment was composed of two factors(affective commitment, calculative commitment). The coordinating leader organization and integrative thinking leader organization positively influenced the work satisfaction, but the bureaucratic hierarchy organization negatively influenced the work satisfaction. The coordinating leader organization and group creative organization positively influenced the employment and relationship satisfaction. The group creative organization and external innovators' collaborative organization positively influenced the affective and calculative commitment, but the bureaucratic hierarchy organization negatively influenced the affective commitment. In addition, there were significant differences in the coordinating leader organization, integrative thinking leader organization, employment and relationship satisfaction by the gender. And there were significant differences in the group creative organization, bureaucratic hierarchy organization, affective and calculative commitment by the age.

Distance dynamics model is an excellent model for uncovering the community structure of a complex network. However, the model has poor robustness. To improve the robustness, we design an enhanced distance dynamics model based on Ego-Leader and propose a corresponding community detection algorithm, called E-Attractor. The main contributions of E-Attractor are as follows. First, to get rid of sensitive parameter ${\lambda}$, Ego-Leader is introduced into the distance dynamics model to determine the influence of an exclusive neighbor on the distance. Second, based on top-k Ego-Leader, we design an enhanced distance dynamics model. In contrast to the traditional model, enhanced model has better robustness for all networks. Extensive experiments show that E-Attractor has good performance relative to several state-of-the-art algorithms.

본 연구는 디자인의 프로세스를 2단계모델과 3단계모델로 구분하고 이들 각 모델의 효율성에 대하여 검증하였다. 2단계모델은 디자이너의 창의적인 마인드를 바탕으로 주관적이고 감각적으로 수행하는 디자인활동을 의미하며 반대로 3단계모델인 경우 객관적이고 논리적인 소비자 중심적자인 활동을 의미한다. 기존 연구에서는 이러한 두 가지 모델에 대하여 상대적으로 어떤 모델이 더 효과적인가에 대하여 의견의 일치를 이루어내지 못하였다. 본 연구에서는 이들 두 모델에 대하여 시장선도전략(market leader strategy)과 시장탐색전략(market seeker strategy)의 개념을 통해 각각의 효율성을 제시하였다 즉, 실증분석을 통해 명성브랜드라면 2단계모델을 바탕으로 한 시장선도전략이 그리고 비명성브랜드인 경우에는 3단계 모델을 바탕으로 한 시장탐색전략이 더 효율적이라는 상황적 입장을 제시하였으며 다만 어떤 상황에서 어떤 모델이 더 효율적인지에 대한 다각적인 검토가 더 필요하다고 제안하고 있다.

Purpose: The study examines how emotional leadership affects employee attitude towards work engagement. Leader legitimacy perception is chosen as the mediating variable to understand the effect of emotional leadership on employee work engagement. Research design, data and methodology: The research model is based on theory and empirical research findings in order to examine the mediating effect of leader legitimacy perception on the relationship between the manager's emotional leadership and employee work engagement. For this purpose, a survey was conducted among 188 employees of domestic retail distributors. Confirmatory factor analysis (CFA) and survey data confirmed the construct, and the hypothesis was tested by using structural equation modeling (SEM). Results: a) Emotional leadership has positive influence on leader legitimacy; b) Leader legitimacy is positively related to work engagement; c) Leader legitimacy mediates a positive relationship between emotional leadership and work engagement. However, there is no direct effect on work engagement (of employees) from emotional leadership standpoint. Conclusion: Based on the empirical results, implications and future research directions are discussed.

This study was intended to investigate the influences that consumer's price sensitivity, bundle discount type, and price level of the male cosmetics have on consumer attitude. The design of this research was comprised of $2{\times}2{\times}2$ mixed design studies. The first element was high price sensitivity vs. low sensitivity, the second element was the bundle discount type (mixed leader vs. mixed-joint), and the third element was the price level of male cosmetics (high-price brand vs. low-price brand). The results of this study showed that price sensitivity, bundle discount type and price level of male cosmetic had a statistically significant interaction effect on the consumer's quality perception. The quality perception of low-cost brands for high price sensitivity/mixed-joint bundle group was low. The quality perception of low-cost brands for mixed-leader bundled groups did not change significantly even when the price sensitivity became higher. However, it can be seen as the same result that the overall value is higher when suggested the price information in Mixed-leader bundle than Mixed-joint bundle. In particular, this study suggests that price information should be presented in mixed-leader bundles for high price sensitivity and low cast brands.

Purpose: This paper investigates the effects of leader feedback on employee creative problem-solving behavior. It also explores the relevant conditions that maximize the above relationship from the psychological trait and task nature perspectives. Specifically we examine how employee feedback acceptance and task complexity moderate the relationship between leader's feedback behavior on follower creative problem-solving behavior. Finally the three-way interaction among leader's feedback behavior, employee feedback acceptance and task complexity is analyzed for the best conditions to maximize the positive effect of leader's feedback on creative problem solving behavior. Methods: This paper used a cross-sectional design with questionnaires administered to 411 employees working in Korean manufacturing and service firms. It applied a hierarchical regression analysis to test the hypothesized relationships including three-way interaction effect among leader's feedback behavior, follower feedback acceptance and task complexity on follower creative problem-solving behavior. Results: The empirical results of the paper indicated that the leader feedback behavior had enhanced employee creative problem-solving behavior. It was also found that follower feedback acceptance and task complexity positively moderated the relationship between leader's feedback and follower problem solving behavior. In addition, the test of three-way interaction effects also revealed that the higher the levels of both employee feedback acceptance and task complexity, the greater the positive effect of leader feedback behavior on employee creative problem solving behavior. Conclusion: This paper contributes to the leadership and creativity literatures by identifying the role of leader's behavior enhancing employee creative problem-solving behavior and the specific conditions strengthening the positive effect of leader feedback behavior on employee creative problem-solving behavior.

An orbital design method of the formation initialization based on the relative orbital element method is presented. It firstly constructed the relative motion equation of the satellite formation flying in terms of the leader and followers' orbital elements. Then the equation was simplified when the orbit eccentricity of the leader satellite was small. And according to the satellites' mission, a general design method for the relative trajectory was proposed. The advantage of this method is that one can get a very simple analytical formula of each follower satellite's orbital elements when the orbital eccentricity of the leader satellite is zero. The simulation results show that the method is effective.
