In this study, a motion control problem for the vessel towed by towing ship on the sea is considered. The towed vessel does not have self-control capabilities such that its course stability totally depends on the towing ship. Especially, in the narrow canal, river and congested harbor area, extreme tension is required during the towing operation. The authors, therefore, propose a new control system design method in which the rudder is activated to provide its maneuverability. Based on the leader following system configuration, a nonlinear mathematical model is derived and a backstepping control is designed. By experiment results with nonlinear control framework, the usefulness and effectiveness of the proposed strategy are presented.

This paper presents a control scheme for the leader-following formation of multiple robots. The control scheme combines the sliding mode control (SMC) method with the nonlinear disturbance observer (NDOB) technique. The formation dynamics suffer from uncertainties because the individual robots are uncertain. Concerning such formation uncertainties, the leader-following formation dynamics are modeled. Assuming that the formation uncertainties have an unknown boundary, an NDOB-based observer was designed to estimate the formation uncertainties. A sliding surface containing the observer outputs has been defined. Regarding the sliding surface, an SMC-based controller was investigated to form uncertain robots. A sufficient condition in the sense of the Lyapunov theory was proven such that the formation system is asymptotically stable. Herein, some comparison results between the sole SMC method and the second-order SMC method are presented to demonstrate the effectiveness and feasibility of the control scheme for multiple robots in the presence of uncertainties.

Purpose - In accordance with the recent changes in the management environment, leaders are required to have an ability of drawing and inducing potential of each worker. Coaching, as one of the strategies of human resources development, is drawing people's attention. This study aims to inquire about the mechanism of leader's coaching behavior which influences the attitude and behavior of workers. Firstly, this study intends to illustrate what kind of influences the leader's coaching behavior can give on organizational citizenship behavior and turnover intention of workers. Secondly, it plans to verify the mediating effect of authentic leadership in the relationship between leader's coaching behavior and organizational citizenship behavior and turnover intention of workers. Thirdly, it aims to prove the moderating effect of emotional intelligence in the relationship among leader's coaching behavior, organizational citizenship behavior and turnover intention of workers. Research design, data and methodology - In order to figure out how the leader's coaching behavior influences attitude of workers, authentic leadership is considered as mediating effect. As for a moderating effect, we have determined emotional intelligence which attracts attention in the recent studies on organizational behavior, so as to investigate the correlation among variables. As for study sample, it was targeted to 236 organizational members of distribution corporations whose leader's coaching behavior is required. For reaching the purpose of study, SPSS 20 was applied for the analysis. Results - The research findings can be summarized as follows: Firstly, leader's coaching behavior gives significant positive influences on organizational citizenship behavior. Moreover, leader's coaching behavior gives negative influences on turnover intention of organizational members. Secondly, the mediating effect of authentic leadership was proved in the relationship between leader's coaching behavior and attitude of workers. Based on the analysis, it turned out that authentic leadership doesn't give a mediating effect in the bilateral relationship. Lastly, the moderating effect of emotional intelligence was proved in terms of how the leader's coaching behavior influences the attitude of workers. The research result shows that the emotional intelligence influences towards the negative direction, in the correlation between coaching behavior and organizational citizenship behavior On the other hand, in the relationship with turnover intention, It was significant effect. Conclusions - Based on the research findings, we have intended to inquired about the mechanism of leader's coaching behavior which influences the attitude and behavior of workers. Furthermore, in the operational level, the following implications can be given: the importance of coaching activation in the operational level was confirmed, through inquiring into the influence of leader's coaching behavior on workers. Moreover, the importance of emotional intelligence, which has been steadily raised, was also confirmed. It is necessary for future study to carry out additional research on various factors of coaching which can influence the effectiveness of coaching, for instance, coaching process, coach's competency, characteristics of coaching customers, relationship with coaching customers and coaching system.

The Purpose of this study is to find out differences among the leader's traits on the hierarchy of Nurse managers in Nurse system of the hospital. In this study 152 managers over head nurse working in 6 University hospitals and 5 general hospitals were selected and the questionary paper answered by them was collected from 1st to 30th in September in 1997. The measuring instrument used in this study is the one integrated and classified by Stogdill (1981), which nurse professor and 2 students of the master's course translated and modified with myself. And its validity was verified through making a test on 130 nurses. The measuring instrument used in this study is made up of 4 items about physical characteristics, 3 items about social background, 4 items about intelligence and ability, 17 items about personaity, 6 items about task-related characteristics, 9 items about social characteristics and 8 items about general background in the triats of leader. And this instrument is made to be marked using five point Likert type. It's reliability is Cronbach's Alpha =.93. The data for study were analyzed through SPSS/PC+ The result of this study are as follows: 1. The order in importantly perceptible degree of the leader's traits showed like these: the intelligence and ability (M=4.683), the task-related characteristics (M=4.605), the personality (M=4.39), the social characteristics (M=4.327), the social back-ground (M=4.056), the physical characteristics (M=3.601). 2. The order in degree to percept the importance of 44 detailed items of the leader's traits showed like these: the judgement and decisiveness (M=4.967), the sense of responsibility (M=4.904), the activity and energy (M=4.796), the self-confidence (M=4.776), the creativity (M=4.748), the intelligence (M=4.743), the responsibility in the pursuit of objectives (M=4.743), the enthusiasm (M=4.717), the objectivity (M=4.704), the moral sense and ethical conduct (M=4.704), the ability to enlist cooperation (M=4.694), the strength of conviction (M =4.678), the enterprise (M=4.691), the administrative ability (M=4.678) and the cooperativeness (M=4.638) 3. As the result of analyzing the leader's trait differences on the hierarchy of nurse managers in six factors of the leader's traits, the social background showed the meaningful differences(F=4.983, P=0.008). 4. As the result of analyzing the leader's traits defferences made from the upper first to 15th rank among the detailed items of the leader's trait factors on the heirarchy of nurse managers, the meaningful defferences appeared in the following items: the objectivity(F=3.413, P=0.033), the creativity (F=3.550, P=0.031), the sense of responsibility(F=3.345, P=0.049), and the administrative ability (F=3.363, P=0.037). 5. As the result of analyzing the leader's trait factors in general background, only the social background of 6 leader's trait factors showed the meaningful differences according to the working place (F=4.057, P=0.008). The study shows that we should consider the above leader's trait factors in selecting nurse managers and that we should develop the educational program for hierarchy of nurse managers urgently.

This paper proposes a formation control method by which multi-mining robots maintain a specified formation and follow a path. To secure the path tracking performance, a pure-pursuit algorithm is considered for each individual robot, and to minimize the deviation from the reference path, speed reduction in the steering motion is added. For the formation, in which two robots are parallel in a lateral direction, the robots track the specified path at a constant distance. In this way, the Leader-Follower method is adopted and the following robot knows the position and heading angle of the leader robot. Through the experimental test using two ground vehicle models, the performance is verified.
