It is a multipurpose organization with a membership of 105 cooperatives, 87 regional cooperatives, 15 business-type cooperatives and 3 manufactures' cooperatives. Accordingly, this thesis examines the marketing of fishery cooperatives in Korea, and in particular considers the marketing channel strategy of fisheries products. No company can perform by itself all the activities involved in the production and distribution of its products and services to its final markets. It must work with other firms to get the job done. Thus marketing channel firms of the fisheries products include primarily the fishery cooperatives, the licensed dealers and the merchant middlemen. The goal of marketing is in matching of segments of supply and demand. Every producer seeks to the link the marketing channel firms that will help it accomplish its objective best. This thesis tries to attempt to improve the present Korean Fishery Cooperatives marketing activities. The purpose of the operation of fishery cooperatives is to guarantee the profits of fisherman as well as the interests of general consumers by eliminating the inordinate profits of middlemen and by narrowing other market margins. Fishery cooperatives marketing activity functions forming a self-helf organization for economic protection of producers themselves, and acting as a market reformational institution through its transaction by group. The following are the characteristics of fishery cooperatives marketing. \circled1 Fishery cooperatives is organized with an economic factor and a personnel factor. \circled2 Fishery cooperatives is non-profit organization. \circled3 The members of fishery cooperatives is independent constitution of economy, but they are closely connected with the cooperative. \circled4 Fishery cooperatives is a mutual aid organization. The objective of an efficient marketing strategy may be well described by the common saying provides the right product at the right time, the right place, and the right price. But it is quite true that the Korean Fishermen's Cooperative can be said to owe its development to the successful implementation of the marketing system. The use of the marketing system has resulted in the following marketing strategy. 1. The direct marketing system. \circled1 The cooperation between the fishery cooperatives and the other cooperative through the collection and delivery center. \circled2 The selling between the fishery cooperatives and the large scale retailers through the process industry. 2. The vertical marketing system. \circled1The fishermen's cooperative to be nominated by wholesaler in the terminal market. \circled2 Contracted vertical marketing system. \circled3 Abolition of selling by double auction in the landing and the terminal market. 3. The physical distribution system. \circled1 The need for adoption of cold chain system to connect production directly to consumption. \circled2 The need for more expansion of landing markets and terminal market facilities. Solutions to the problems of the Korean fishery are made possible through effective functioning of cooperative marketing activities of fishery products. The marketing concept of fishermen's cooperative lies in the satisfaction of consumer needs. According to the marketing concept fishermen's cooperative should try to satisfy customer's needs through a coodinated set of activities that allows the organization to achieve its goal. Providing satisfaction to customers is the major trust of the marketing concept. To do this, a business must find out what will satisfy customers. With this information the cooperative sells to the greatest possible number of customers through the most efficient sales and marketing channels. Economic rationality of fishermen's cooperative marketing lies in reduction of marketing cost and elimination of intermediate institutions. Cooperative marketing and direct marketing are both indispensable marketing factors for a new cooperative organization among the manu ways. The cooperation between the fishermen's cooperative and the others cooperative, and vertical marketing system are the most necessary ones. Propulsion of cooperative marketing system could not be successful without the support of the marketing instituion's help. Consequently, successful cooperative marketing ought to lead to the necessity not only for the improvement of marketing organization, but for the application of a new marketing concept in the fishermen's cooperative.

We analyze a systematic relationship between transaction mechanisms and wholesale pricing schemes within a supply-chain with two competing suppliers and a monopolistic retailor. When one of the suppliers changes its transaction mechanism from an independent scheme to a cooperative one, then the wholesale prices of the suppliers become cheaper than before. When one supplier changes its transaction scheme to a cooperative one while the other supplier sticks to the existing independent transaction scheme, we show that the supplier with a cooperative transaction scheme can realize the increased profit via a profit sharing contract with the retailer but the supplier with independent transaction scheme can face the decreased profit. We also show that both suppliers can achieve the higher profits by adopting the cooperative schemes with the retailer.

We have developed a new optimization algorithm termed simple bacteria cooperative optimization (sBCO) based on bacteria behavior patterns [1]. In [1], we have introduced the algorithm with basic operations and showed its feasibility with some function optimization problems. Since the sBCO was the first version with only basic operations, its performance was not so good. In this paper, we adopt a new operation, rank replacement, to the sBCO for improving its performance and compare its results to those of the simple genetic algorithm (sGA) which has been well known and widely used as an optimization algorithm. It was found from the experiments with four function optimization problems that the sBCO with rank replacement was superior to the sGA. This shows that our algorithm can be a good optimization algorithm.

Recently, the educational community has attempted to implement the theory of multiple intelligences. In approaching multiple intelligences, teachers have applied the same structural approach which has been so successful with cooperative learning. Cooperative learning is easy to learn and implement, fun for teachers and students, and produce profoundly positive outcomes along a remarkable number of dimensions. Different structures are designed for different outcomes, including enhanced mastery of subject matter, improved thinking skills, team building, class building, development of social character and social skills, communication skills, classroom management, classroom discipline, and development of and engagement of each of the multiple intelligences. Cooperative learning is becoming an increasingly popular teaching strategy. In this study, it is aimed to clarify the application of cooperative learning in health education. Cooperative Learning in health education enhances student learning by: 1) providing a shared cognitive set of information between students, 2) motivating students to learn the material, 3) ensuring that students construct their own health knowledge, 4) providing formative feedback, 5) developing social and health group skills necessary for success outside the classroom, and 6) promoting positive interaction between members of different cultural and socio-economic groups. Cooperative Learning structures and techniques in health education are following. Flash Card, Focused Listing, Structured Problem-solving, Paired Annotations, Structured Learning Team Group Roles, Send-A-Problem, Value Line, Uncommon Commonalities, Team Expectations, Double Entry Journal, Guided Reciprocal Peer Questioning, What if. Because the purpose of health education is the practice, therefore health specialists have to guide powerful and effective teaching method The application of cooperative learning in health education may improve its effectiveness.

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'.

Cooperative spectrum sensing increases the detection performance in a cognitive radio network, based on the number of sensing nodes. However, as the number of sensing nodes increases, the reporting overhead linearly increases. This paper proposes two kinds of cooperative spectrum sensing with limited reporting in a centralized cognitive radio network, a soft combination with threshold-based reporting (SC-TR) and a soft combination with contention-based reporting (SC-CR). In the proposed SC-TR scheme, each sensing node reports its sensing result to the fusion center through its own reporting channel only if the observed energy value is higher than a decision threshold. In the proposed SC-CR scheme, sensing nodes compete to report their sensing results via shared reporting channels. The simulation results show that the proposed schemes significantly reduce the reporting overhead without sacrificing the detection performance too much.

The purpose of the study was to identify the effects of LT cooperative learning and traditional competitive learning on academic achievement by the level of learning ability in industrial high school students. The results of the study were as follows; the score of posttest of the experimental low grade group was significantly higher than that of control low grade group (p<.05), and the score of posttest was significantly higher than that of pretest in the experimental low and middle grade group (p<.05). Based on these results, it was concluded that LT cooperative learning had positive effect on the enhancement of industrial high school student's academic achievement than the traditional lecture learning. Its effect on high grade students was negative, but its effect was significantly positive on both middle grade and low grade level students.
