This research studied learning model for the purpose of renovation of mathematics teaching methods. Especially, this research classified the types of cooperative learning, the theoretical background for cooperative learning, the need of cooperative learning in school mathematics, and the differences between cooperative learning and traditional small group learning, This research also suggested special features of cooperative learning and various types of cooperative learning models. The main types of cooperative learning which this research supported are TAI(Team-Assisted Individualization, JIGSAW cooperative learning, JIGSAW II cooperative learning, JIGSAW III cooperative learning, STAD(Student Team-Achievement division) cooperative learning, and TGT(Teams-Games-Tournament).

In wireless ad hoc networks, nodes communicate with each other using multihop routed transmission in which hop-by-hop cooperative diversity can be effectively employed. This paper proposes (i) two cooperation models for per-link cooperation (PLC) and per-node cooperation (PNC) for exploiting cooperative diversity in wireless ad hoc networks and (ii) a cooperative routing algorithm for the above models in which best relays are selected for cooperative transmission. First, two cooperation models for PLC and PNC are introduced and represented as an edge-weighted graph with effective link quality. Then, the proposed models are transformed into a simplified graph and a cooperative routing algorithm with O(n2) time is developed, where n is the number of nodes in the network. The effectiveness of the algorithm is confirmed for the two cooperation models using simulation.

본 연구는 우리나라 통합 도서관 협력체제 구축을 위한 모델 개발을 목적으로 하였다. 현재 국내도서관 협력체제의 현황은, 국립중앙 도서관을 중앙관으로 한 공공도서관 협력망을 비롯하여 지역별 관종별 협력체제가 구축되어 도서관 기능의 활성화를 도모하고 있으나 기능적으로 보다 효율적인 협력이 필요한 시점에 있다. 이러한 관점에서 다양한 형태의 국내도서관 협력체제를 정비하여 새로운 통합 도서관 협력체제를 구축하기 위한 모델을 제시하였다.

Since 1982, the government of Korea has actively promoted vertical cooperative R&D programs between government-sponsored research institutes (GRIs) and private firms. A number of firms participated in the programs because cooperative R&D could lower the risk and could contribute to rapid commercialization of many technologies. This paper examines the effectiveness of vertical cooperative R&D projects by the modes of cooperation between GRIs and industrial firms, and analyzes the performance of participating firms' technology sourcing strategies for commercial utilization of cooperative R&D results at the project performed from 1982 to 1989 under the Government-Industry Cooperative R&D Program sponsored by the Ministry of Science and Technology(MOST) in Korea. The cooperative R&D projects are classified into 4 groups by two criteria, i.e., the level of participation of firms, and the breadth of cooperation. The findings suggest that firms should actively participate in cooperative R&D projects. In addition, in order to enhance commercial success, cooperation between GRIs and industrial firms should not be limited to R&D stage only. The breadth of cooperation should be extended to commercialization stage. Small- and medium-sized firms participating in vertical cooperative R&D projects in Korea usually lack internal technological capabilities that are needed to commercialize the results of cooperative R&D. Three different technology sourcing strategies - exclusive cooperative R&D strategy, in-house development augmented cooperative R&D strategy, and licensing-in supplemented cooperative R&D strategy - are empirically derived through cluster analysis of the relative usage rates cooperative R&D and of other supplementary technology acquisition methods. The findings suggest that the firms participating in vertical cooperative R&D projects should try to utilize other supplementary technology acquisition methods in order to achieve commercial utilization of the vertical cooperative R&D results.

Objectives : This study was performed to compare consciousness of doctors on cooperative practices of western medicine and traditional Korean medicine, and to provide policy implication for development of cooperative practices. Methods : The structured questionnaires were mailed to 132 doctors working in non-cooperative practicing university hospital and 77 doctors working in cooperative practicing hospitals in Busan metropolitan city. The response rate was 40.2% and 40.3% respectively. This survey was performed from 10 Oct. 2008 to 31 Oct. 2008. Results : The doctors working in general hospital had comparatively negative consciousness on basic concept, value and necessity for cooperative practices and traditional Korean medicine. In regards with disease treatment's effectiveness of cooperative practices, both groups evaluated musculoskeletal and immune disease were more effective than others. There were positive relationships between perception for cost-effectiveness and consciousness on intention to participate cooperative practices(p<0.05). Also doctors who experienced traditional medicine treatment had positive consciousness on cooperative practices(p=0.05). Conclusions : To activate cooperative practices of western medicine and traditional Korean medicine, some efforts should be carried out. These include promoting cooperative education programs in medical schools and traditional Korean medical schools, doing research on cost-effectiveness of cooperative practices, and trying to minimize legal and systemic restrictions for cooperative practices.

The purpose of this study was to explore a paradigm for the development agricultural cooperative unit in Korea. To fulfill the purpose of the study, both a review of literature and case studies was used. The agricultural cooperative units selected for the survey were Doduram Swine, Songtan Cooperative Organization, Okyung Cooperative Farms, and Harim Poultry Company. To identify major factors and limitations associated with effective management of agricultural cooperative units, selected cooperative units for production, processing and marking were surveyed and analyzed. This study identified four major factors to be included in a development paradigm of effective agricultural cooperative units which were: 1) active participation of farmers, 2) techniques end attitude of participants, 3) horizontal integration of a high technology enterprise with agricultural production, and 4) increasing cooperative work on production and marking within the unit. Based on the results of the study, the following recommendations were made for further improvement and development of agricultural cooperative units : First, farmers should be encouraged and motivated to participate actively in agricultural cooperative units. Second, participants of the agricultural cooperative units should be equipped with both technical knowledge and skills on agricultural production, processing and marking. Third, a national net-work system should be established for the agricultural cooperative units throughout the country. Fourth, agricultural cooperative units should be expanded to various agricultural sectors covering wider area. Finally, agricultural cooperative units should be supported by farmers, agricultural organizations and the government for more effective management and further development.

This study is the analysis of the effects of Jigsaw II Cooperative Learning upon the academic achievement and upon the ability of self-directed learning, compared to lecturing. It made it experimental target for two male and two female classes of students in the 2nd grade of humanity high school in Ulsan metropolitan area. One male and one female classes conducted Jigsaw II cooperative learning by making up a small group heterogeneously from the aspect of learning ability, and the other male and female classes carried out the lecturing focusing on a teacher. As for the academic achievement of science, Jigsaw II cooperative learning was shown to be effective compared to the lecturing. As for the ability of self-directed learning, Jigsaw II cooperative learning was indicated to be effective compared to the lecturing. As for the ability of self-directed learning for Jigsaw II cooperative learning, it was indicated to be effective compared to the lecturing. Given seeing this, it was identified the necessity for Jigsaw II cooperative learning to be applied to a school field as an alternative plan for the lecturing.
