The area of agriculture and fisheries business are expanding according to changes in the agriculture and fisheries environment. For the direction of long-term practical field training of department of Agriculture and Fisheries Business, which is a newly created department of Korea National College of Agriculture and Fisheries, production as well as other areas must be reviewed. The original long-term practical field training and the direction of selecting a long-term practical field training appropriate for the new department reviewed in this study are as follow. First, the original long-term practical field training can be summarized as single product-focused management, inadequate connection of production-processing-service areas, and individuality-focused management. However, a case management that sees new value creation as a basis of agricultural development can be summarized as diversification of value creation, horizontal integration, entrepreneurial management through corporate management, and leading management for regional revitalization through connecting local agricultural. Therefore, the direction of selecting the new department's long-term practical field training requires seeking of value creation management through horizontal integration, exploration of agricultural businessmen who have entrepreneurship needed to create added value in agriculture, and a way to connect to the original production-centered long-term practical field training.

The effects of high carbohydrate diet on growth, serum physiological response, and hepatic heat shock protein 70 expression in Wuchang bream were determined at $25^{\circ}C$ and $30^{\circ}C$. At each temperature, the fish fed the control diet (31% CHO) had significantly higher weight gain, specific growth rate, protein efficiency ratio and hepatic glucose-6-phosphatase activities, lower feed conversion ratio and hepatosomatic index (HSI), whole crude lipid, serum glucose, hepatic glucokinase (GK) activity than those fed the high-carbohydrate diet (47% CHO) (p<0.05). The fish reared at $25^{\circ}C$ had significantly higher whole body crude protein and ash, serum cholesterol and triglyceride, hepatic G-6-Pase activity, lower glycogen content and relative levels of hepatic growth hormone (GH) gene expression than those reared at $30^{\circ}C$ (p<0.05). Significant interaction between temperature and diet was found for HSI, condition factor, hepatic GK activity and the relative levels of hepatic GH gene expression (p<0.05).

In Korea, the agricultural machinery market has been generally on the rise, and particularly the demand for the diverse agricultural machine is increasing due to the radical changes in agriculture, such as a high supply of the advanced and automated agricultural machine and an increase in aged or female farmer population. Therefore, this study analyzes the technical trends in the precision agricultural machine domestically and globally to guide the direction of development of the ICT-based machine. The investigation of the precision agricultural machine in this study focuses on the production technology through analyzing the trends in sensor-related technology, the decision-making research, variable treatment technology, and academic publication. The result shows that information processing technology including the sensor and the decision-making requires various measurement factors and the established technologies are continually being developed.

This study aims to propose the policy direction for agriculture and fisheries heritage system in Korea. The agriculture and fisheries heritage system is defined as traditional agricultural activity systems and landscapes which should be preserved, sustained and handed down and evolved from the co-adaptation of a community with its cultual, agricultural, biological environment. The key characteristics of the agriculture and fisheries heritage system of Korea are as follows; Firstly, this system designates software and hardware factor of heritage in integrative manner. secondly, this system seeks to preserve and utilize such heritages simultaneously. Thirdly, this system intends to strengthen the role of people in rural area. Fourthly, this system makes use of new engine of growth in agricultural community. This system is designed by comparing and reviewing several related domestic and foreign systems including FAO' GIAHS.

Judicious control of high temperature is the most important task for the successful intensive-cultivation of vegetables in glasshouses during the hot summer. Estimation of cooling load and wise selection of suitable equipments and facilities based upon the environmental conditions are essential for the efficient temperature control. A series of experiments were carried out to investigate VETH(ventilation, evapotranspiration, temperature and humidity) plot was prepared for the possible practical application in designing some evaporated cooling methods for the following 9 locations; Seoul, Seosan, Taejeon, Pusan, Cheju, Kwangju, Taegu, Chonju, and Chinju.

To elucidate the mycotoxin production of Penicillium, Aspergillus and Fusarium spp. isolated from round bale silage, TLC analysis of culture filtrates were conducted. Mycotoxin citrin and patulin were detected from culture filtrates of Penicillium paneum. Aflatoxin was detected from culture filtrates of Aspergillus flavus. Gliotoxin are known to produce by A. fumigatus was not detected. Mycotoxins produces by Fusarium spp., Fumonisin, zearalenone and deoxynivalenol was not detected in the culture filtrates of Fusarium proliferatum.

Forty-one Enterococcus faecalis (E. faecalis) isolates from feces of pigs and chickens in Korea were screened for the presence of virulence factors. Gelatinase activity (85.4%, 35/41) was the more commonly observed phenotype of virulence in E. faecalis, compared with hemolytic activity (12.2%, 5/41). Thirty-one of 35 (88.6%) gelatinase-positive E. faecalis isolates harbored the gelE and fsrABC genes. A gene encoding for the enterococcal surface protein (Esp) was detected in 24.4% (10/41) of the isolates. All beta-hemolysin-producing isolates harbored the esp gene.
