농촌 소하천의 수리학적 및 수질특성을 반영한 모형을 개발하였다. 모형구조 설계시 제어체적 기법을 활용하여 하천 형상, 수질 및 유량의 변화가 심한 농촌 유역의 소하천에 대한 수질의 모의하였다. 개발한 모형에 난수발생기법을 도입하여 최적 반응계수와 모형구조를 추정하였다. 또한 모형 보정기준의 일반화를 위해 동의지표와 효율계수를 도입하여 매개변수추정의 신뢰성 향상을 도모했다. 모형의 적용성을 검증하기 위해 경남 김해시 한림면 용덕천에서 수질을 채취하여 분석

The objective of this study is to analyze 1) the law system in relation with the development permissions 2) characteristics of the development permissions change 3) especially focusing on the development permissions changes in agricultural, forestry and fisheries facilities in light of socio - economic conditions in Korea Greenbelt. The following results were obtained: 1) The purpose of Greenbelt in Korea is to control the land use in order to protect the surrounding areas from urbanization. 2) During the 1990s, the number of formulated development regulations increased one and half times than that of the previous decades(1970s 1980s). The main reasons are advancements of local autonomy and democratization. 3) Three patterns were observed with respect to ease the regulations in agricultural, forestry and fisheries facilities those are: (1) increase in types of businesses ; (2) increase the maximum area permitted ; (3) decrease in qualification for establishing facilities. 4) There were few development permissions in a agricultural, forestry and fisheries facilities in consideration to the regional agricultural condition. The development permissions were only during the period of restricted to use (1979.12~1993.11). We propose that the authority of development permission should be given to the local autonomy government, because the local government has the knowledge of its individual agricultural conditions.

For rational agricultural land use planning, it is quite necessary to get hold of land suitability precisely and to make decision on land use patterns accordingly. In the methodological viewpoint, objective and scientific evaluation techniques for land suitability classification should be supported for the systematic land use planning. As one of technical development approaches to rational land use planning, this study tried to frame a land suitability evaluation system for agricultural purposes. Evaluation unit is defined as a tract of land bounded by road, other land units and topographical features. And quantification theory was applied in the determination works of evaluation criteria. The administrative area of Namsa-myon(district), Yongin-si(city), Kyunggi-do(province) was selected for the case study. In order to check the feasibility of the evaluation system developed in the study, field check team, consisting of 2 government officers and 2 representative farmers, carried out evaluation works by observation on 148 sample land units, 10% of total 1,480 ones. Between estimated and observed results, there showed very good relationship of its multiple correlation coefficient, R=0.9467.

Temperature, relative humidity and ventilation are closely related one another, and they are the main factors to be controlled for the environmental control system of a storage facility. Conventional environmental control systems do not consider the interrelationship between temperature, relative humidity and ventilation, which results in low performance and high energy consumption. To overcome the inefficiency of the conventional ones, it was developed an on-off control system based on the interrelationship between the factors. The usefulness of the system was illustrated with the results produced by a set of experiments in a real world.

In this paper, the basic planning for the creation of consolidated agricultural institutions of Choongcheongnam -Do and its management schemes were established. These institutions, including rural development office, farmers'training institution, original seeding field of farm crops, agriculturial information center, packing design center, agricultural machinery repair center, agricultural scientific conference hall, agricultural museum, agricultural park, farmers'hall and event plaza, are planned to be created. The required area for the site is 1,246,781 m2. 281-22 Jongkyung-Ri, Sinam-Myun, Yesan-Gun, Choongcheongnam-Do and its surroundings is a proper site for the creation of'consolidated agricultural institution because the actual conditions of the soil, traffic network, irrigation and drainage, tourist routes and human resources are very good. The layout of the facilities that would comprise an agricultural institution was organized in consideration of the functions and roles of each facility and the relationships among facilities in this consolidated agricultural institution. It is desirable that the headquaters of consolidated agricultural institution oversees the management department, the planning . administration . information department, the rural development office, the farmers'training institution, the original seeding field of farm crops and the agricultural park.

The objectives of the study were to. 1) explain the seriousness of environmental problems and the importance of environmental education in rural development , and 2) explore more effective and efficient ways of environmental education for agriculture and rural development in Korea. The world has rapidly changed and concepts such as clientele -centered, efficiency, and globalization are flowing under this change. Agriculture or rural development is not an exception. In order for agriculture as an occupation and rural communities to have competitiveness in efficiency and attractiveness, it is important to develop and execute a well-planned program for agriculture and rural development. Otherwise, farmers and rural inhabitants will continue to leave the agriculture and rural areas. Frequent recent reports of newspapers on nit and water pollution, including nutrients and pesticides have brought attention to the seriousness of environmental problems in Korea. Environmental concerns should consider in planning and executing the rural development program. People want to get contamination-free foods, water and fresh air. They can and are willing to pay their money for high quality food, water and a better living environment, as their incomes have been increasing, Agriculture and rural communities may have competitiveness in these aspects. It is irony that environmental concerns makes the possibility of changes in agriculture and rural development in Korea. Environmental education will have an increasingly important role in agriculture and rural development. Environmental problems relate to the human behavior in various aspects. Many environmental problems are mainly rooted to people's ignorance and spending-habits, and lack of technology related to environment. These human behaviors are the focus that environmental education should teach and change. Environmental education has been carried out through various subjects in school education in Korea, but "Environment" in middle school and "Environmental Science" in high school were separated as a regular subject from 1996. Environmental education still has a lot of room for development from a theoretical frame work. Environmental education should be carried out as action-oriented, student-centered programs. Various teaching materials, programs and proper supporting budget should be developed so that environmental education fulfills its necessary role well in agriculture and rural development. A textbook about the environment alone will not guarantee a high quality environmental education.
