  • Since the coastal countries, such as Unite States and other Latin America countries, proclaimed their 200 nautical mile Exclusive Economic Zone, these countries have attention to the need to develop effective coastal management and resource conservation But these countries often perceive themselves as being in competition with each other for profitable for the expansion of the vested EEZ. In such a situation, Exclusive Economic Zone expansion can appear as attractive policy tools in a coastal fishing firms in a noncooperative rivalries with pelagic countries, enable them to expand their fishing share and earn more profits. In reality, the coastal countries strategic Exclusive Economic Zone expansion change the initial condition of the game that both countries' fishing firms play. In this case, the coastal countries' fishing, such as South Korea, Japan and others, act as a followers. As result, the coastal countries' welfare is improved because of pelagic countries profit share shifts to the coastal countries profit share. In this paper, we find that coastal countries strategic EEZ expansion policy may not improve the coastal contries welfare if the shifting profits are dominated by the direct lobbying costs and related resource depletion.

  • In this paper, we propose a method using neural network (NN) to improve the motion control of a decentralized control system for cooperative transportation. In our former work, a decentralized control system for transporting a single object by multiple nonholonomic mobile robots has been developed. One of these mobile robots acts as a leader, who is assumed to be able to plan and to manipulate the omnidirectional motion of the object. Other robots, referred to as followers, cooperatively transport the object by keeping a constant position relative to the object. in this work, it is assumed that the leader can not only plan but also broadcast the local velocity of the object. Then...

  • The purposes of the study were (1) to seg-ment the female college apparel market based on fashion life style and (2) to develop a pro-file of each segment regard to self-concept, shopping orientation and patronage behavior. The data were collected through questionnaire by random sample of 526 female college students. By cluster analysis of lifestyle factors, three groups were identified, (fashion leaders, fashion followers and fashion aversion) Three groups were then compared through multivariate analysis of variance and chi-square statistics on 10 self-concept variables, 6 shopping statistics on 10 self-concept variables, 6 shopping orientation factors and 1 patronage behavior variable. Significant difference were found among the three groups on all these variables which indi-cate that fashion lifestyle can be a useful base for segmenting female apparel market and these groups are unique in terms of self-con-cept, shopping orientation and patronage behavior.

  • According to the social learning theory, leader' organizational citizenship behavior (OCB) is a predisposing factor for follower' OCB, because they acknowledge and imitate leader as a desirable example of behaviors for organizational and individual success. We investigate social learning effect of leader OCB on follower OCB and examine the moderating role of political skill in the mediated relationship between leaders OCB and follower OCB (with followers' affective organizational commitment as the mediator). We find that follower's affective organizational commitment may mediate the relationship between leader OCB and follower OCB. Furthermore, we find that follower with high political skill may focus on the instrumental value of OCB. Political skill moderates the relationship between follower' affective organizational commitment and follower OCB. Data from 325 leader-follower dyads support the hypothesis. Theoretical and practical implications of these findings are also discussed.

  • Cam mechanisms are used commonly in many automatic machinery. Disk cam mechanisms has 4 different types according to the different types of followers. The motion characteristics of the cam mechanisms depend on the shape of the cam and the type of the follower. This paper performs the motion analysis for a disk cam and follower mechanism using a circular arc method and a coordinate transformation method in order to find a contact point of the cam and follower. The velocity is calculated by using the instant velocity concept. Also, the acceleration is determined on using the central difference method. As the results, this paper presents the original curve and the analyzed curve for the motion analysis of the disk cam for an example.

  • The rate of wear of cam followers in a valve train system is mainly a function of contact stress between the cam and the follower, sliding velocity and hydrodynamic film thickness between the two mating surfaces. The wear or surface fatigue can be reduced by maximizing the elastohydrodynamic film thickness. In this paper, an attempt has been made to estimate the optimal specific film thickness of cam-follower system quantitatively. A general TES polynomial function with real values of exponents is developed and genetic algorithm (GA) is used as optimization techniques for maximizing the minimum specific film thickness. The optimization programs enumerate values of the exponents for synthesis of cam displacement curves. The results show that the minimum film thickness can be increased considerably, e.g. approximately 7% in this paper.

  • The purpose of this study would be to find out the relationship of social as a sign of fashion image and the followership. This study is classified into theoretical and experimental research. Following are the summary of the results revealed through the experimental study. First, The relationship of oneself pursuit of fashion image types and leader's favourite fashion image types for regression analysis result indicated significant difference. Second, The factor analysis of followership are used, developed by Colangeol is asking. The results of factor analysis are four types classification as to Active Participation, Convergence objective, Team Spirit, Critical Thinking. Third, The relationship of types of fashion images and factor variance of followership indicated a difference in Active Participation factors. But The relationship of types of leader's fashion images and factor variance of followership indicated a difference in Convergence objective factors. Analysis of the fashion image based on the conceptual properties of followership is to understand the characteristics of followers, and the leader's image based on research for building materials will be provided.
