  • We prove convergence properties of the global solutions to the cooperative cross-diffusion system with the intra-specific cooperative pressures dominated by the inter-specific competition pressures and the inter-specific cooperative pressures dominated by intra-specific competition pressures. Under these conditions the $W^1_2-bound$ and the time global existence of the solution for the cooperative cross-diffusion system have been obtained in [10]. In the present paper the convergence of the global solution is established for the cooperative cross-diffusion system with large diffusion coefficients.

  • According to the Fisheries Cooperative Law, the Fisheries Cooperative has made a substantial contribution to the development of Korea's fisheries industry amid the nation's rapid economic growth and drastic social changes since its establishment in April 1st 1962, It is, however, generally believed that the cooperative has made a poor performance in improving its business constitution. Therefore, the reform of its board of director system is one of the ways to strengthen the constitution. For the purpose of making the board of director system to operate rationally, this dissertation is divided into five chapters. Chapter I provides an overview of this study, such as research background and objectives. Chapter II focuses on the Fisheries Cooperative's board of director: its function, composition, and election. Chapter III analyzes the responses of the Fisheries cooperatives to questionnaires about the board of director system, and subsequently presents the causes and the meaning of the analysis results. Chapter IV deals with the various ways to improve the Fisheries Cooperative's board of director system, including director and cooperative governance. Finally, Chapter V draws a conclusion of this study. The independent function of the Cooperative's board of director and responsible directorship is one of the most important factors which can prevent the Cooperative from insolvency. Unlike the past, not only it has become difficult to keep the Cooperative's business under the government's support, but also the Cooperative itself is now facing a situation where the support from the government cannot be expected. This ist he reason why the Cooperative should manage itself autonomously, workout its organization, and respond to the current situation with a renovativemanagement and business strategy. Therefore, a rational operation of the board of director is urgently needed.

A Study on the Relationship between Organic Agriculture Activity and Cooperatives Role in Wonju - Utilizing Delphi Technique - (원주지역에서의 유기농업 활동과 협동조합 역할과의 관계 연구 - Delphi Technique을 활용한 인식조사 -)

  • This study started with two questions. The first question is 'Why does organic agriculture want to be linked with cooperative?' The second is 'What is the characteristics of the mutual relationship between organic agriculture and cooperative?', especially in Wonju. Up to now, there have been various kinds of discussion about cooperation between organic agricultural campaign and cooperative in Wonju. But there are few concrete data showing what role cooperative plays in the cyclical process of production-distribution-consumption of organic agriculture. Thus, we conducted a survey applying the Delphi technique to the 35 organic agricultural specialists active in Wonju. First, small-scale family farm producers established a social economic cooperative network in around 2003 to perform 'the activities of innovators' through forming an organization. Producers moved from the stage in which they were supported one-sidedly by consumers to the stage where they could 'lead' cooperation. Each farm organization built a vertical integration, and horizontal cooperative systems with other farm organizations. But, practical cooperative activities have remained in the doldrums. They tend to show trends deviating from the principles of organic agriculture and cooperative. Second, the relationship between producers and consumers in Wonju can be described as 'producer-consumer cooperative type'. In Wonju, the producers' organization is not a sub-contractor which simply deliver organic agricultural products to producers' cooperative, but is an equal subject which creates its own value chain. The cooperative (cooperative organization) leads distribution and consumption of organic agricultural products and mutual communication. But, the closeness between producers and consumers has got loosened. And, it is problematic that the proportion of local food consumption in Wonju is very low. There is a very strong tendency to ride the central distribution system of producers' cooperative coalition. Consequently, it is necessary for producers' cooperatives in Wonju to run a local food distribution system based on the 'cooperative system among cooperatives'.

  • The majority of small/medium sized shipbuilders in Korea is poor in capital and then, should be restructured as an efficient production system with low investment. Due to considering this situation, the cooperative work system is proposed, in this study, as more effective production system for small/medium sized shipbuilder The cooperative work system Is the production system that many small/medium sized shipbuilders in a group jointly share the common facilities except minimum equipments and have managerial cooperation such as joint purchase of raw materials. The efficiency of cooperative work system is proved from economic and technical point of view with the case study of FRP shipbuilders of Sapjin industrial complex located at Mokpo area.

  • In human-mechanical cooperative systems, a significant issue is to improve the control performance and the maneuvering feeling of human operation. However, since it is not easy to evaluate the feeling of operators numerically, control engineers design controllers only through experience. Thus, in this paper, a new evaluation method for control performance of human-mechanical cooperative system is proposed based on the reserge waveform. Various distortions of waveform represent deteriorations of control performance and maneuvering feeling. In some cases, since there is a tradeoff between the control performance and the maneuvering feeling, it is difficult to compensate for both of them by usual feedback controllers. To overcome this situation, the two degrees of freedom control system is applied to human-mechanical cooperative system. Some numerical simulation results for an electric power steering system are shown to confirm the effectiveness of proposed control design method.
