In this paper, we consider cooperative elliptic systems under conjugation conditions. We first prove the existence of the state for 2 × 2 cooperative elliptic systems with Dirichlet and Neumann conditions, then we find the set of equations and inequalities that characterizes the optimal control of distributed type for these systems. The case of n × n cooperative systems is also established.

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.

The study aimed to examine the effects of cooperative learning in science teaching on scientific knowledge, inquiry ability, and science - related attitudes. This study has carried out LT strategy. The cooperative learning was applied to the experimental group for 8 weeks with worksheets developed for this study, The results were statistically analyzed by SPSS. The results are as follows: Students of cooperative learning made significant progress in scientific knowledge(p<.05), inquiry ability(p<.01), and science - related attitudes(p<.05). The students in the cooperative classes have shown that the cooperative learning was good for causing interest. inducing active participation, and helping students' learning. and students showed strong wish for the continuous cooperative loaming.

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.

Purpose: The purpose of the study was to develop a cooperative clinical nursing education model in response to the challenge to provide quality clinical instruction for nursing students. Method: A hypothesized model was developed based on literature review and Cho's partnership model of preservice teacher. Final model was refined with cooperative committee meetings, workshop and post clinical education meetings. Results: A Cooperative clinical nursing education model was developed with three phases(collaboration, planning, redefinition of major roles) and ten constructs(organization of cooperative committee, goal setting, partnership contract, planning objectives, and operating manual). Conclusion: The Cooperative clinical nursing education model support the need for continued collaborative partnership between nursing college and hospitals to foster quality clinical instruction.

본 연구는 협동학습에서 소집단 경쟁을 유도하는 집단보상과 소집단 구성원의 결속을 강조하는 협동기술 훈련의 효과를 비교하기 위하여 시도되었다. 이를 위하여 초등학교 6학년 3개 학급을 대상으로 문제중심 협동학습을 실시하였고 2개 학급에서는 각각 집단보상과 협동기술 훈련을 실시하였다. 학업성취도 면에서 이질적으로 구성된 소집단별로 진행된 협동학습 후에 세 집단의 과학성취도와 학습동기 점수를 성취도 수준별로 비교 분석하였다. 본 연구의 결과, 첫째, 집단보상과 협동기술 훈련이 과학성취도에 영향을 미쳤으며 학습자의 학업성취 수준에 따른 차이가 나타났다. 즉 성취 수준 상위인 학습자에게는 집단보상이 협동기술 훈련보다 효과적인 반면 하위인 학습자에게는 협동기술 훈련이 집단보상보다 효과적이었으며 중위인 학습자는 집단보상과 협동기술 훈련이 모두 효과적인 것으로 나타났다. 둘째, 집단보상과 협동기술 훈련이 학습동기에 영향을 미쳤으나 학습자의 학업성취 수준과는 관련이 없었다. 학습동기의 하위요소별로는 주의력 요소에는 효과가 없었으나 자신감과 만족감 요소에는 효과가 나타났다.

This study aims to examine how cooperative teaming of small ability level groups influences the enhancement of their scholastic achievement in mathematics. The conclusions are as follows; 1. The students which participate in cooperative learning in small ability level groups demonstrate academic improvement over those that participate in non-cooperative learning groups. 2. In particular, this method is more effective for high-level classes, than for middle or low-level students. 3. The learners' perception, interest and attitude towards mathematics has not changed through their placement in small ability groups involved in cooperative activities.

The purpose of this study was to reveal analyze the relationship between status of participation in an oral health care program and oral health outcomes among patients in Korea, and to evaluate the results to provide evidence regarding the feasibility of widespread implementation of the program. Patients were designated as either cooperative or non-cooperative with the oral health care program and were assigned to each group accordingly. Modified dental hygiene process (M-DHP) of the oral healthcare program was modified to form the dental hygiene process. The study included 48 patients at a dental clinic in Busan, Korea. Questionnaires were used to collect information on oral health behavior (OHB), clinical examination was used to record bleeding on probing (BOP) and O'Leary index, and phase microscopy was used to identify microorganisms. Differences between groups were evaluated using repeated measures ANOVA. Our results showed that the group cooperative with the oral health care program showed greater improvement in OHB, BOP, and O'Leary index than the non-cooperative group. Second, patient satisfaction with the M-DHP was very high, particularly for content and the friendly nature of the staff. The cooperative group showed greater improvement in oral health than the non-cooperative group for all metrics. Our results suggest that this low-coste program, if implemented, would be actively accepted and utilized in dental clinics.

The primary purpose of this study was to provide the basic materials for C.V.A inpatients' actual use of medical service at the hospital with both the western and oriental medical department and the attitude on cooperative treatment. The results of this study were as follow: First, the subjects' general characteristics including job, monthly mean income and age made statistical differences to their pathological characteristics such as part of primary paralysis, detailed name of disease and cause of elicitation. Second, their general characteristics including religion and job produce statistical difference to their actual use of medical service, like medical institution form, term of treatment and type of medical institution at first-aid. Third, through the awareness of cooperative treatment system, the effect of C.V.A treatment and the shorten of the C.V.A treatment term were higher at oriental medical department inpatients and cooperative treatment serviced inpatients than western medical department inpatients and cooperative treatment non-serviced inpatients. Fourth, the biggest problem on current dual medical system is increase medical expenses and the biggest reason on not vitalized cooperative service is prejudice of both parts.
