The Korea National Agricultural College (KNAC) was established as a special three academic years(six semesters) course by the Presidential Act in July 1995 and opened on March 20, 1997. According to the Act, the students of KNAC are granted free boarding in dormitory, full support of educational expenses, and, after completion, exception in military service and financial support for farming, which is their obligation to do for a double period of the total school year. With these institutional favors KNAC is hight expected to bring up promising young farm managers in Korea. However, actual competitive young farm managers are brought up by the well organized education with emphasis on learning by doing approach. With the relation to the education this study was performed to review and examine present situation of faculty organization, facilities and equipments, curriculum including field training in home land and oversea's counties. This study found out that there were undesirable aspects such as unbalanced faculty members among the departments, lack of practice farm land and limited budget in field training, which should be improved to achieve the objectives of KNAC.

One of the way of the preserving environment is the circulation of materials. Japan's cereal food self-sufficiency rate is less than 30%. Japan imports more than 30 million tons of food every year. Japanese are afraid of international food trade giving damages to environment. Advanced farm mechanization integrated with precision farming is an answer to solve these problems. Crop scientists, soil scientists and agricultural engineers at Kyoto University cooperate together in studying precision agriculture for paddy rice since 1996. Automatic follow-up combine and autonomous vehicle have been developed. Remotely sensing by using machine vision has been studied to measure nitrogen contents. Field map i.e. soil, growth and yield, in paddy field of 0.5 ha has been made. In this report the concept and objectives of advanced farm mechanization and precision agriculture research at Kyoto University are introduced.

The purpose of this study is to examine the difference between service quality satisfactions according to tourists' preference and segmentation by various motivations. Data were collected from 442 farm stay visitors by field surveys in rural areas. A factor-clustering method identified three distinct segments; want-it-all, overall low motivation, relaxation. MANOVA was used to examine the differences of service quality satisfaction for farm stay visitors' preference and segmentation by motivation. Results show that the type of guest room more significantly influenced farm stay visitors' satisfaction according to those three clusters. It should be noted that we have information on the characteristics and type of satisfaction of the consumers in order to improve the quality of farmstay's service in rural tourism.

본 연구는 영농규모화에 대한 전개과정과 충남지역 쌀 생산기반을 검토하고 쌀 산업의 미래지향적 방향의 한 축을 이어갈 쌀 전업농의 영농규모화를 통한 그 대안을 모색하는데 있다. 이 목적을 완성하기 위해 조사된 내용을 요약하면 다음과 같다. 1. 충남지역이 쌀 생산은 전국에서 가장 높으며 재배면적에서도 제2위를 차지하고 있다. 이는 그만큼 쌀에 대한 국제적 정세변화는 충남의 쌀 생산농가에게 지대한 영향을 미칠 수 있는 개연성을 높여준다. 쌀 생산의 핵심이 되는 전업농가 수는 도내 전체농가의 7.7%를 차지하고 있고, 이들의 평균 경작면적은 2.9ha 이다. 이 면적은 규모화사업을 위해 지원된 자금이 크게 주효한 결과라고 해석된다. 2. 1980년대 후반부터 2002년까지 추진된 충남지역 영농규모화사업은 충남지역에 쌀 전업농가의 경영규모를 19,484ha까지 증가시켰다. 또한 1995년부터 2002년까지 매매사업이 이루어진 농가 수는 6,431농가에 1,6517ha가 매매되었으며, 장기임대차사업은 같은 기간동안 7,059농가에 면적은 6,970ha에 이르렀다. 다만 농지교환분합사업은 210ha에 1,864농가가 참여하였는데 이처럼 농지교환.분합사업이 활발하지 못한 것은 은퇴자들이 영농에 넓은 면적을 요망하지 않아 구태여 규모화사업에 응하지 않더라도 생활에 지장이 없기 때문이다. 또한 교환과 분합작업에 따른 복잡성 등, 일반 사회적 여건도 농지의 교환분합사업에 부정적인 방향으로 작용했던 것으로 추정된다. 3. 영농규모화사업을 촉진하기 위해서 제안된 방안들은 다음과 같다. (1) 재촌탈농자 및 고령 은퇴자를 위한 전직 프로그램 및 사회보장프로그램을 수립하고 농지매매 촉진을 위한 각종 인센티브제를 도입하여야 할 것이다. (2) 효율적인 쌀 생산시스템을 확립하기 위하여 단위면적당 생산량을 증대시키고 생산비를 낮추는 제 방안이 강구되어야 한다. 이를 위해서는 쌀 생산기술과 경영적 능력을 갖춘 생산조직이 육성되어야 하며 시설의 적정배치 및 정보화가 완비되어야 한다. 그리고 영농시스템 구축에 바탕을 둔 지역종합의 다양한 구조개선도 병행하지 않으면 안 될 것이다. (3) 경영규모를 확대, 개선하기 위해서는 개별경영규모를 확대하거나 집단규모를 활용한 방안이 강구될 수 있을 것이다. 이상을 종합하면 충남의 영농규모화사업은 성공적으로 수행되어 왔다고 할 수 있으나, 궁극적으로 이 사업이 소기의 목적을 달성하기 위해서는 부수되는 제반 문제점을 적절히 해결해 가지 않으면 안 된다. 그리고 쌀 전업농에 대한 적절한 지원 및 탈농자 및 은퇴자에 대한 종합대책수립은 충남의 영농규모화사업을 완수하는데 반드시 선결되어야할 사항이다.

The objective of the this study is to find a way to increase fm household income through investigating their computer applications. We utilized the 2000 Korea Agricultural Survey data and applied a Heckman Selection Model to correct a selection bias. The present study found the following results. First, determinant of income among fm households by the level of computer applications has significant statistical differences based on their choices of computer applications. Accordingly, the application of general linear regression about fm income without adjusting these choices may cause statistical fallacy. Second, it has been reported that increasing the member of household is not directly related to increasing the fm income. In case of computer-own farm household, the effect of decrease in income according to increasing in age was predicted. However, in the fm household not possessing computer, it shows negative relationship. It shows that an agricultural career of farm owner and educational attainment of all farm household members have positive relationship regardless of computer possession. The income of the farm household those main field is not agriculture is also found to be lower than that of farm household whose major earnings come from agriculture.

Background: A definite diagnosis should be made in the bovine practice field, however, it was difficult to perform laboratory analysis immediately. Currently, three types of portable blood gas analyzers are available in Korea. Objectives: This study aimed to evaluate the correlations among these three analyzers. Methods: Seventy-two plasma samples from Holstein-Friesian cows were used for blood gas analysis, and three instruments (EDAN i15 Vet, VETSCAN i-STAT, and EPOC) were operated simultaneously. Moreover, plasma calcium levels were compared between these portable analyzers and blood chemistry device, which is usually used in a laboratory environment. Pearson analysis was performed to confirm the correlation of each parameter produced with the three instruments and blood chemistry analyzer. Results: As results, high correlation was observed in parameters of pH, pO₂, potassium ion, ionized calcium, and glucose (p < 0.001, r > 0.7). In addition, pCO₂ showed a moderate correlation among the three analyzers (p < 0.001, r > 0.5), and there was no correlation among all instruments for sodium ions. There was also a high correlation between ionized calcium from the three portable devices and total calcium from the biochemistry analyzer (p < 0.001, r > 0.9). Conclusions: In conclusion, there was a high correlation between results from the three different blood gas analyzers used in the bovine clinical field in Korea. Thus, a consistent diagnosis can be made even with different equipment if the operator is aware of the strengths and weaknesses of each piece of equipment and operates it properly.

With the worldwide trend of controlling the utilization of fossil fuels inducing global climate change, many efforts will have to be made on securing a sustainable energy supply. Tidal current is a concentrated form of gravitational energy, its resource is significant, but limited locations. To effectively capture tidal current energy from the sea, a group of tidal turbines should be formed and positioned with optimal size and spacing for absorbing from multiple points. Thus, the flow field including turbines becomes a huge domain, a so-called tidal farm. It can be very convenient technically and economically if a whole turbine farm is simulated by means of actuator disc thoery. So, the analysis method using actuator discs coupled with a solution of Reynolds Averaged Navier-Stokes (RANS) equations is adopted for actual tidal turbines. Actuator discs have regions where similar forces imposed by actual turbines are applied to a flow. As working in group formation, turbines naturally have interaction effects on one another. Therefore, the present paper investigate the evaluation on the operating performance of tidal farm in terms of the mutual influence among turbine units with various lateral and longitudinal spacing. Authors expect that results of the present study contribute to the development of tidal farm for the future potential energy.

A three-dimensional flow simulation was performed to investigate the wind flow around wind-power generation facilities on mountainous area of complex terrain. A digital map of eastern mountainous area of Korea including a wind farm was used to model actual complex terrain. Rotating wind turbines in the wind farm were also modeled in the computational domain with detailed geometry of blade by using the frozen rotor method. Wind direction and speed to be used as a boundary condition were taken from local meteorological reports. The numerical results showed not only details of flow distribution in the wind farm but also the variation in the performance of the wind turbines due to the installed location of the turbines on complex terrain. The wake effect of the upstream turbine on the performance of the downstream one was also examined. The methodology presented in this study may be used in selecting future wind farm site and wind turbine locations in the selected site for possible maximum power generation.
