This work was conducted to obtain some information about stable production of high quality seed-tubers in the late season cultivation of virus-free sweet potato [Ipomoea batatas (L.) Lam.]. Growth characteristics and storage root yield between virus-free and farmer's slips in 9 cultivars were investigated using black-film vinyl mulching cultivation with $75{\times}25cm$ planting density on July 10. At 30 days after planting, vine length, vine diameter, number of node, and number of branch in virus-free slips were significantly increased than those in farmer's slips. The vine growth was significantly different among cultivars, and vine elongation was excellent in 'Kogeonmi', 'Shincheonmi', 'Shinhwangmi', 'Shinyulmi', and 'Yeonhwangmi' compared to the other cultivars. At 110 days after planting, vine length, vine diameter, number of node, number of branch, and fresh weight were significantly different among cultivars, but no significant differences between virus-free and farmer's slips were seen except number of node. Total yield in virus-free slips was increased by 12-49% among cultivars than that in farmer's slips. The mean yields between virus-free and farmer's slips were 1,625 kg/10a and 1,230 kg/10a, respectively, and it was significantly different between virus-free and farmer's slips. Percentage of marketable storage root in virus-free slips was 65.6%, and it was significantly higher than 57.8% in farmer's slips. Marketable yields ($40g{\leq}$) between virus-free and farmer's slips were 1,067 kg/10a and 710 kg/10a, respectively. Marketable yield in 'Shincheonmi', 'Shinyulmi' and 'Shinzami' was more than 1,300 kg/10a, and these cultivars showed to be highly adaptable for the late-season cultivation among 9 tested cultivars.

Purpose: This study was carried out to investigate the prevalence and the main factors influencing the farmer's Syndrome in farmers in Korea. Method: A survey questionnaire was completed by 238 farmers who lived in 8 agricultural districts in Seosan City. The data were collected from April 10 to May 5, 2002. Results: The prevalence of the farmer's Syndrome was 42.6%, and its prevalence rate in woman was higher than that in man. The prevalence of the farmers syndrome proportionally increased with advanced age. Variables that were positively correlated with the farmer's syndrome were age, duration of farming, days of resting, and the number of the agricultural chemical's poisoning. On the other hand, variables that were negatively correlated with the farmers syndrome were smoking, sleeping hours, economic condition, and level of educational. In a regression analysis, the factors influencing the farmers syndrome were age, sex, sleeping hours, days of resting, and the number of the agricultural chemical's poisoning, which accounted for 25% of the total variance. Conclusion: Based on these study results, older age and woman gender are the remarkable risk factors influencing the farmer's syndrome. Sleeping hours, days of resting, and the number of the agricultural chemical's poisoning were also the significant attributable variables to the farmers syndrome.

This study was to get basic data for the establishment of proper labor counterplan so that we estimated farm work volume and work loads by crops. We examined the method of work practices such as a work posture, work time, measured work environment such as hot, cold, humidity and ultraviolet rays and calculated physical loads induced by them. Also we surveyed work environment, work posture, sleeping time and work time because they affect on farmer's health. Farmer's health survey was investigated by questionnaire and measured farmer's physical load. The types of farm work were classified into greenhouse farming, rice farming, dry field farming, stock farming and special crop farming. 11 crops were selected, for example, greenhouse melon, riceㆍred pepper, milky cow farming, pear, grapes, dropwort, sweet potato, potato, radish, and cabbage. We also chose subject districts haying the most yield of 11 crops. Our survey was conducted for the period when farmers think the hardest period in physical work load. The farm work models based on work standard were presented according with farmer's health.

The realization of agricultural modernization, the solving of the "three rural" issue as well as the increment of farmers' income is one of China's top priority. Thus, under the support and encouragement of government's relevant policies, China has introduced the "Supermarket-Farmer Direct Purchase" which is a new mode for the supply of agricultural products. This is an innovative of agricultural products circulation mode, and the comprehensive promotion will help supermarkets get cheap goods directly from the hands of farmers, thus forming price competitiveness; farmers can also get profits and subsidies from supermarkets which can eliminate middlemen's profit, thus increasing their revenue; consumers can both get a guarantee of food safety and save expenses, and the win-win situation for the supermarkets, farmers, and consumers will be achieved. However, the dilemma between "farmers having difficulty in selling" and "supermarkets having difficulty in buying" is still frequent. So in this thesis, through theoretical research and situation analysis, each relevant part of the "Supermarket-Farmer Direct Purchase" mode will be studied as a whole. Moreover, effectiveness will be evaluated and relevant problems will be identified. Then, based on foreign experience and our national conditions, new modes and advice will be provided for users in different circumstances.

This research was for reviewing the people return to farm and rural area, and recommend to some policy implication for supporting it. For the study, literature review was doing and seeking about return farmer meaning and motive, return type, moving problems, adaptation problems, satisfactions degree and farm life and rural life continuance will, and return farmers' characteristics. Based on the study, twelve policy recommendations offered.

미리 제작되어 있는 소프트웨어 컴포넌트를 조립하여 소프트웨어 개발공정을 산업화하는 과정인 CBD(Component Based Development)는 Farmer 모델에 의하여 설계된 시스템을 실제로 구현하기 위하여 매우 적합한 개념이다. CBD개념의 도입을 위하여 Farmer 모델이 갖는 개체노드, 측면노드 및 KLB/OLB 등과 같은 객체들이 수행하는 기능에 대한 명세를 나타내는 인터페이스 명세 모델이 반드시 필요하게 된다. 본 논문에서는 Farmer 모델에 의하여 정의된 개념을 컴포넌트 인터페이스 메타모델에서의 개념으로 변형시키는 방안에 대하여 설명하고 있다.

The purposes of this study were to analyze the farmer education programs in Korea and to develop the strategies for improving its effectiveness. Questionnaires were used to collect data from institutes of farmer education. The framework of analysis was developed with four survey areas and 328 programs were analyzed based on it. The results show that the major learning domains of farmer education were concentrated on production skills and were overlapped with other training institutes. There was no systemic structure in whole programs for farmers. Evaluations for learning achievement were not fully implemented. It was recommended that there should be a system for improving quality of farmer education.
