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.

현재의 양식업을 살펴보면 영세 양식어업인 중심의 정책으로 운영되어지고 있다. 이러한 정책의 문제점은 대규모의 자본 및 신규 인력의 진입이 어려운 부분이 있다는 점이다. 이 문제로 인해 양식업 종사자의 고령화로 양식업에 피해가 발생하고 있다. 본 논문은 위와 같은 인력 문제를 해결하기 위해 아두이노를 이용한 양식장 스마트화를 제안한다. 이 방법은 사물인터넷을 기반으로 양식장의 자동 제어 및 원격 통신을 이용한 수동 제어가 가능하며 센서들의 값을 어플리케이션으로 전송받아 핸드폰으로 받아 볼 수 있다. 또한 단순한 양식을 떠나 실시간으로 자연의 생태환경을 유지하는 효과를 보이고 최적의 생육환경을 맞추어간다는 점에 있어 기존 양식장의 어류와 비교해보았을 때 더 높은 품질의 어류를 기대해 볼 수 있다.

A major challenge in the transition from conventional to organic production in a grain intensive region such as the Com Belt legion of the U.S.A. is how to profitably select and manage a crop relation. The opportunity cast of forgoing grain production for forage and green manure crops is significant. Many organic researchers and writers emphasize the need to bring an animal enterprise into the farming system for diversification and enhanced labor utilization. Livestock also add value to grain and forage crops to offset decreased grain production and can recapture nutrients used in crop production that can be recycled through manure. In grain intensive regions, organic farmers should consider swine production as a natural fit for the farming system. Swine are very efficient and adaptable animals that can add value to both grain and forage crops. While somewhat lacking, there is a reasonable body of literature on organic and sustainable swine production. However, there is relatively little specific information available to organic farmers to assist in the initial decision to enter organic swine production and to evaluate marketing alternatives. The primary focus of this paper is to give some background on organic animal production(emphasis on swine) in the Central United States and outline production and marketing decisions and considerations, relative to market trends, demographics and standards(U.S.). At the farm level, decisions must be made regarding resources, such as land, labor, financial and social capital, all relative to opportunities, all in the context of the standards and market forces beyond the farm. At the personal level the farmer must also make decisions about convictions regarding organic or environmentally friendly agriculture, willingness to change, impacts on lifestyle and family, and the transition to organic methods within the planning horizon of the farmer and the family business.

Distribution of farm produce in Korea is known to be inefficient due to the numerous stages that exist in the distribution channel. This has resulted in dissatisfaction for both farmer and consuers; farmers sell their produce at low prices to middlemen while consumers pay high prices for them because of price increases that occur in the distribution chain. We apply Spengler's theory of double marginalization to show that price increases are inevitable as the length of the farm distribution chain increases. We then show that the negative effects of double marginalization can be contained by setting up a physical distribution center. The physical distribution center effectively reduces the stages in the distribution from 5 or 6 stages to 3 or 4 stages. We also lay out the design and major characteristics of the distribution center, as well as the expected cost savings.

This study was conducted in order to figure out the energy consumption pattern in rice production system of Korea, with literature investigation focused on energy requirement in rice production system in worldwide. The investigation reveals that 24,994 MJ/ha was needed to produce 4,500kg of rice production or 5.55 MJ/kg was consumed. The major enegry consumptions are resulted from the application of nitrogen fertilizer, fuel for farm machinery, and farm machinery embodied energy, which showed somewhat different energy consumption pattern than that of the developed country, like, U.S.A. Based on the machinery chosen in this investigation, it was found that 32.7% of the fuel energy, 2,431.8MJ, was consumed in drying operation, 32.2%, 2.402MJ, in tillage and land preparation. 25.8%, 1.923.6MJ in harvest. A linear relationship was found in pre harvest energy input and output of rice production.

The significance of this study was to analyze the quality value of organic livestock pork for the first time based on the results of managing and testing the cycling organic farming of black pork and vegetables within farm for two years. The results of analysis could be summarized as follows. First, the pork of experimental group with crop-livestock cycling farming showed the excellent quality and high consumer preference compared to the control group of general pork or pork from non-crop-livestock cycling organic farming. In the content ratio of Omega-3 as a representative essential fatty acid, it was 1.46 that was about 2.8 times more than general pork (0.52). In case of Omega-6, it had about 2.5 times more than general pork. Especially, the U/S ratio value which was the content ratio of Unsaturated Fatty Acid (UFA, U) of Saturated Fatty Acid (SFA, S), was largely shown in pork (2.93) from cycling organic farming. Second, it would be necessary to maintain the economies of scope shown in crop-livestock cycling organic farming, and the high quality value of livestock products. For this, there should be a value chain model that could realize the economies of scope and economies of scale at the same time based on scaling and diversification through cooperative organization between farmers. Through this, it would be possible to establish a cycling model called 'community cooperative agriculture' by forming local internal markets through cooperation of production-processing and integration of distribution-sale-consumption. For the managerial activation of this cooperative organization, the government should promote/support the small crop-livestock cycling organic farming cooperative organization in local unit. For securing the reliability of crop-livestock cycling organic agricultural products and crop-livestock cycling organic livestock products, it would be necessary to review the introduction of Participatory Guarantee System (PGS).

This paper aims to provide quite recent information on the organic industry in the U.S. Major focuses are on the development of cultivation and marketing of fresh and processed organic produce and foods, newly enforced certification program, consumers' purchasing behaviors toward organic foods, and social survey results administered to the organic farmers in the U.S. The U.S. recorded 8 billion dollars' sale of organic foods in 2000, which was the largest in the world and showed 23% growth compared to the previous year. Yet the organic industry is still a niche market, occupying merely 1.5% of total food sale amount. The natural foods markets have not been so concentrated in the U.S., but it is changing and a few wholesale mart such as Whole Foods is emerging. Recent introduction of new certification program provide unified and sole standard at the federal level to which every certifier needs to adjust itself in order to be acceredited by the government. According to a social survey, consumers purchase organic foods because they concern about health, they stick to their own modes of life favoring natural foods, and so on. Another social survey shows that most organic farmers sell their produces to wholesalers, distributers, or producer coop, and direct sale to visitors at their own farm comprises of about 8 percent of their organic land.
