The purposes for this study was to provide information for developing educational programs for U-turn farmers' based on their needs on rural settlement. Special objectives of the study were; 1) to survey the general characteristics of U-turn farmers including motives. preparation, and education, 2) to investigate problems and difficulties of the U-turn farmers in rural settlement 3) to identify the reasons for success and failure in U-turn filming, and 4) to provide information in developing programs for U-turn farmers. Data for the study were collected from 526 U-turn farmers throughout the country, and after data cleaning, 494 questionnaires were used for data analysis. Based on the results of this study, the following were recommended for further development of U-turn farming programs; 1) to facilitate and expand continuous surveys on the motives. preparation, education and information for U-turn farmers will be neceassary to update the important and current information on U-turn farming. 2) Further examination of the problems and difficulties of U-turn farmers would be necessary to develop appropriate policies and educational programs for U-turn farming. 3) continuous investigations on the reasons for success and failure of U-turn farming would be necessary to develop appropriate apicultural policies. 4) for more effective educational programs for U-turn farmers. selection of educators, institution, curricular and timing etc. Should be carefully designed to meet the practical needs of the U-turn farmers. 5) more research activities should be encouraged to improve program development and implementation of U-turn farming.

U.S. organic farming has grown rapidly-20 percent or more annually-throughout the 1990s, which kept pace with consumer demand for organically produced food. Thus certified organic acreage is the total to 235 million acres in 48 state in 2001, and SO the U.S. ranked fourth in land area managed under organic farming systems. And according to several surveys, consumer's reasons for purchasing organic food are health and nutrition, taste and environmental concerns. California and North Dakota were the top two states in 2001 for certified organic cropland; the former with mostly fruits and vegetables, and the latter with wheat, soybeans, and other crops. And the top two states for certified organic pasture were Colorado and Texas. And then several states such as Iowa and Minnesota have begun subsidizing conversion to organic farming systems as a way to capture the environmental benefits of these systems. The price of organic produce fluctuates rather broadly because of being traded by market economy principle and of demand-supply disequilibrium. Nevertheless, average price premiums for organic produce are higher than the prices for the produce under conventional farming. Future prospects for U.S. organic farming are as follows; Demand for organically grown foods is expected to continue growing at a rapid pace, as more growers convert to organic production and more processors and distributors expand organic selections in their product lines. And new processed products and new types of healthy foods are likely to appear on the market, and some new organic products will be aimed at mainstream markets.

Recently, USN technology has been spreaded to all areas of application systems. In addition to urban application systems such as u-City, u-Home and u-Education, u-Farming(ubiquitous farming) technology supports agricultural innovations in the farm. In the u-farming environment for livestock or plant production, key environmental factors i.e. temperature, humidity and luminosity are to be set optimally to increase productivity and safety by applying USN technology. This approach could change agricultural environment. In this paper, we proposed an implantable micro sensor node to be implanted into laying hen to monitor deep body temperature. This sensor node uses SoC(System-on-Chip) designed for USN. In addition to that, we discussed about further considerations on the practical use of proposed sensor node.

Organic farming including organic livestock farming in EU has been extended since the latter half of the 19th century. Especially, the organic farming area of Italy, Spain, Germany and U.K. is extensive compared to other EU countries. And organic farming area has been extended rapidly in Portugal and Greece. EU will have an influence on many countries' organic farming on the history and world agriculture. If FTA reaches between Korea and EU, livestock products like ham or sausage will be imported a great deal from EU. So Korea has to establish countermeasures to livestock products export strategies of EU.

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).

In this study, land farming and chemical oxidation of a diesel-contaminated site is compared to evaluate the environmental impact during soil remediation using the Spreadsheet for Environmental Footprint Analysis by U.S. EPA. Each remediation process is divided into four phases, consisting of soil excavation, backfill and transportation (Phase 0), construction of remediation facility (Phase 1), remediation operation (Phase 2), and restoration of site and waste disposal (Phase 3). Environmental footprints, such as material use, energy consumption, air emission, water use and waste generation, are analyzed to find the way to minimize the environmental impact. In material use and waste generation, land farming has more environmental effect than chemical oxidation due to the concrete and backfill material used to construct land farming facility in Phase 1. Also, in energy use, land farming use about six times more energy than chemical oxidation because of cement production and fuel use of heavy machinery, such as backhoe and truck. However, carbon dioxide, commonly considered as important factor of environmental impact due to global warming effect, is emitted more in chemical oxidation because of hydrogen peroxide production. Water use of chemical oxidation is also 2.1 times higher than land farming.

The definitions of organic farming method has rather philosophical meaning than application of agricultural practices. The meaning of organic farming method has certainly basic differences in comparison with the conventional farming methods. The main definitions of organec farming method have certainly to reduce or not to apply any kinds of farm inputs materials by increasing quality of agricultural prod-ucts. However, the quality of produced food by organic farming method should be improved in compari-son with cinvethional farming method. By applying organic method, the qualith of food, envir-onment as well as spiritual attitude of human being should be improved in future. Actually, there are very wide fields of research on organic farming methods such as production tech-niques, soil and water conservation, plant and animal production, marketing and consumers behavior on organic products. In this article the present situation of organic farming methods in the United States of Americal is investigated in cimparison with conventional rice production. The production cost of rice per acre in the United States of America mde 58, 788 Won in 1986, while it was 121, 699 Won in Korea having about 107 percent higher in Korea than tham the U.S.A There is a larger rice farm cost analysis between conventional and organic rice farm in California. The cash cost pre 1 lbs of conventional rice made 4.86 $, while the organic rice was 6.96$ showing about 43.2%higher level of cost in organic products(1 lbs=0.45359kg) At present, there is less econmic advantage of organic rice production in California because of lower yields as well as price levels, Therefore, the total net return over cash cost peracer/yeat was a little lower in organic rice production than conventional rice prouction.

U-turn migration is one of the prominent phenomenon after IMF controlled Korean economy. However a number of U-turn migrants were settled in rural area before that time. This paper is aims at studying the socio-economic effects of U-turn migration in rural area. The study results are summarized as follows; First, migrants are relatively young and engaged in overall parts of the farming. The farmer with age under 50 is represented at 71.4% of migrants comparing with 53.7% of those farmers in rural area. Second, owing to the increasing number of U-turn migrants, the decreasing price of rural wages, the decreasing of idle land, and the increasing price of farm land are the outstanding phenomenon at present. Third, even though there are many kinds of supporting systems for U-turn migrants, the systems are not so successfully functioned. For the successful supporting system they must be changed for the individual migrant rather than target group.

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.
