The degree to which people share knowledge has major impacts on the effectiveness of virtual community of practice (VCoP). As an extension to the previous study which investigated the effect of individual cooperative types (cooperator, reciprocator, and free rider) on knowledge sharing, it is investigated how much increase in the degree of cooperation will enhance knowledge sharing when there are more knowledge contributors and strong ties exist across the community. Simulation method is adopted to measure the effect of the cooperative type and tie strength on knowledge sharing. The results reveal that the tie strength positively affects knowledge contribution in VCoP and strongly tied VCoP generates equivalent level of knowledge contribution as that of weakly-tied VCoP with 5% more contributors.

In this study, we propose an efficient expert system (ES) construction mechanism by using dynamic knowledge map (DKM) and database management systems (DBMS). Generally, traditional ES and ES developing tools has some limitations such as, 1) a lot of time to extend the knowledge base (KB), 2) too difficult to change the inference path, 3) inflexible use of inference functions and operators. First, to overcome these limitations, we use DKM in extracting the complex relationships and causal rules from human expert and other knowledge resources. Then, elation database (RDB) and its management systems will help to transform the relationships from diagram to relational table. Therefore, our mechanism can help the ES or KBS (Knowledge-Based Systems) developers in several ways efficiently. In the experiment section, we used medical data to show the efficiency of our mechanism. Experimental results with various disease show that the mechanism is superior in terms of extension ability and flexible inference.

The purpose of this study was to develop long and short-run educational programs for u-turn farmers based on their need assesment. This study was conducted by review of literature and surveys. Subjects of this surveys were 310 participants of agricultural training programs developed by the Rural Development Administration for u-turn farmers in 1997 and 1998. According to major findings, many participants were faced with problems such as financial shortage, deficiency of farming skills, difficulty of marketing, new neighbours unfavourable gazing and farm labour shortage. These problems could be classified into the problems at their preparing stage and the problems of adjusting stage in their farms. And also the participants suggested that educational programs for them contain knowledge based teaching and technical practices with focus on their problems solving. With their suggestion various knowledge and technical modules were selected. Using these module several kinds of long and short-run educational programs could be developed.

이 연구의 목적은 농업 재래지식(indigenous knowledge)이 농업생산과 환경에 미치는 중요성을 알아보고 농업 및 환경교육에 그 필요성을 제시하는 데 있었다. 우리 나라에서는 농업재래지식은 조상 대대로 농업작부체계에서 매우 유용한 농업기술로 이어져 왔다. 그러나 현대의 과학 농업기술에 의하여 최근에 농업 재래지식의 활용은 급감하였고, 이에 대한 체계적인 연구나 보전이 매우 미흡한 상태에 있다. 그러나 미국, 일본, 케냐 등 많은 국가에서는 여전히 농업 재래지식이 농업생산 및 농촌개발 과정에서 그 적용율이 $9{\sim}27%$ 정도로 나타나고 있다. 농업 재래지식은 자연농법 및 유기농법과 함께 중요한 환경보전 기술이므로 실태 파악과 그 보전 방안이 강구되어야 할 것이다.

The Strong Small Farm (SSF) is small farm, but strong farm so that the SSF competes with farm of the world. Also, SSF means that farmer brings about management innovation through improvements of continuous competence and individual efforts. Ultimate goals of SSF are to improve competence of farm household by 20 percent and to increase farm household income by 10 percent. The purpose of this paper is to examine the factors affecting the improvement of competence of the Strong Small Farm. The major findings of this study are summarized as follows. First, the results indicated that competence of farm household was improved by 8.5 percent. Second, the findings showed that management plan report, implement report, precision management consulting and whether or not he or she was urban to rural returner had a significant impact on improvement of competence.

During the last 10 year period, OECD member countries were in a trend of 'less government' from 'more government', thus resulted in restructuring and reducing staffs in government agricultural institutions including the Agricultural Knowledge System. In recognizing the crisis of 'less government', member countries were in a trend of paradigm shift to the 'better government;. In producing and transferring agricultural information, member countries are more concerned about consumers as well as producers as the target of good quality services of the 'better government'. The general consensus of member countries identified the importance of food safety and environmental protection as new agendas for the 21st century. Agricultural Knowledge Systems (AKS) in OECD member countries were in a trend of reorganization in addressing food safety, and agriculture / environmental issues. The approaches, functions and responsibilities were diversified to multi-governmental institutions from the ministry of agriculture. Thus the importance of institutional cooperation and coordination were emphasized more in the newly changed AKS paradigms. The objectives, functions and approaches of AKS in OECD member countries as well as in Korea will be directed to emphasize the importance of environment, sustainable agriculture, food safety, and rural development. They will also focus on establishing mutual cooperative systems among policy makers, consumes, non-governmental organizations, and agri-related organizations as necessary for sustainable development in the future.

The objectives of this study were finding out some methods about development of oversea agriculture in Korea. It is a tough task that faces us now. China is a big agricultural country, most agricultural investment country and the nearest located in Korea. So this study researches on the quality of farmers and characters of rural human resources in China. In China, agriculture industry is the basic industry among national economy developments. The majority of populations in China are living in rural region. Agriculture, villages and farmers are main issues in China. From this point, An analysis of Chinese farmers' characters and qualities; general conditions of farmers' knowledge of science and technology, their education level, quality of minds and sprit, and rural public health service situation in China. The result of this study is following; First, Chinese farmers' factors that low education level, big cultural differences between cities and country sides affect the development of China's agriculture as obstruction factors. Second, Practice conditions of farmers' science knowledge and technology are low level, output of higher rural human resources, low quality of minds and sprit and problems of agricultural extension service. It is negative influenced of agriculture and farmers economic development in China. Third, unsociable culture of the peasantry influences Chinese farming in the negative ways. Also, conventional notions of family are getting weaker, it makes connection of the kinship weaken. But, Chinese think that this kind of kinship is the most important thing in their life. Fourth, in the case of situations that the farmer's sanitation and health, low level of the medical service is getting worse than before relatively. And there are a lot of discordances between a planned childbirth policy and personal recognitions. Also, lacking of nourishment makes labor productivity falling tendencies. The medical industry falls short of the standard as compared to the number of farming people. Fifth, in the peasantry's consciousness of the legal system, this causes difficulties to farmers in the market. Shortage of the legal knowledge exerts a bad influence upon rural economy.
