In the path of agricultural development, agricultural mechanization has played some decisive roles such as protecting natural disaster, substitution of labor shortage in agricultural production and so on. In making our country's agricultural mechanization plan, Japanese agricultural mechanization policy has been frequently referred to but it's very hard to find informative data for systematic analysis of the mechanization policy. In this paper it was tried to analyze the resent trend in Japanese agricultural mechanization policy and it's performance with many materials published in Japan. As the results, four things are recommended to be considered in making Korean agricultural mechanization policy. First, faster enlargement of agricultural machinery size in Korea might be very harmful to drop down agricultural production cost. Second, diverse utilization methods of agricultural machniery should be introduced. Third, a marketing of the used agricultural machinery must be activated to reduce agricultural production cost. Lastly, the joint R & D for developing low price agricultural machniery is necessary for small markets.

The Korean hospitals have been changed a lot from 1970's to 1990's, not only in their space allocation but also in their functions. These changes were affected by the medical development, social atmosphere, increasing population, needs of medical demands, and so on. In this study, we compared net area allocation involve in these affect of hospitals which were built in 1970's, 80's, and 90's, and through this comparison, we analyzed developing tendencies of hospitals. In doing so, we tried to provide basic research data for planning of new hospital buildings.

This Study was to determine the trend of child rearing attitude, to investigate how variables affect the child rearing attitudes, and to suggest directions for developing much needed parental effective training programs or counselling for autistic child in community. The subjects were seventy six mother's of autistic children who attending to 13 treatment institutions in Korea. The data were collected from 1, March to 30, May, 1985. Maternal Behavior Research Instrument exploited by Schaefer, used as 3 tool in this study. The research findings obtained were as follows : 1. Mothers, in general, had affective, restrictive attitudes, and were found to be affective, yet did not give a positive evaluation of children's behavior and used fear control extensively, thus made their children dependent. 2. There were no significant differences in child rearing attitude by children's sex and age. 3. There were no significant differences in child rearing attitudes by mother's age, education level and religion. 4. There was no significant difference in child rearing attitudes by father's occupation.

Growing market of electric vehicles such as hybrid, plug-in hybrid, and bare electric vehicles in the world is accelerating the significance of Li-ion batteries as a renewable green energy. According to such market flow, the developing components such as cathode, anode, electrolyte, and separator, composing the Li-ion batteries, is significantly important tasks for the commercialization. In particular, development of the cathode material having high capacity and stable thermal stability is essential for long-distance electric vehicle in the near future. Herein we introduce various applications of Li-ion batteries such as portable electronics, electric vehicles, and energy storage system, and also its research trend, in particular on the cathode materials.

Modern fashion can be expressed as 'pursuit of cocktail effect', which means not unformed, not bounded by a rule, and mixed with various styles. Among them, the most outstanding trend of style is the'infra-syndrome'which designs underclothes like a ordinary wear, which has outstood since early 1980s. In 1990s, this syndrome made active progress and now facing 21th century, it becomes one of the big trends in fashion. Clothes of infra syndrome are one of attempts for freedom expressed by progressive designers who pursuit new and surrealistic design. The purpose of this study is to maximize the aesthetic beauty of'infra-syndrome'apparel centering on dresses of which designs are notable derived from underclothes. With the sewing techniques using the special facilities of the lingerie-manufacturing industry and making use of new material which can be used far lingerie wear, this research strives to expand new ideas in the lingerie industry as well as to contribute to promoting the dress culture by developing novel lines from a new form of dress and lingerie-foundations of dress suitable for human body.

For developing fatigue design curve of cast stainless steels that would be used in piping material of domestic nuclear power plants, a low-cycle fatigue test rig was built. It is capable of performing tests in pressurized high temperature water environment of PWR. Cylindrical specimens of CF8M were used for the strain-controlled environmental fatigue tests. Fatigue life was measured in terms of the number of cycles with the variation of strain amplitude at 0.04%/s strain rates. The disparity between target length and measured length of specimens was corrected by using finite element method. The corrected test results showed similar fatigue life trend with another previous results.

Washing machines designed to clean laundry have been more widely used at home as they reduce household labor and boost the quality of life. Technological advances and better standards of life increase demand for laundry washing performance. Energy efficiency regulations and consumer demand for the larger trend, washing machine makers should be done in performance studies to reduce power, and water consumption and the load on power transmission devices. In this study, performance of a fully automatic washing machine with unconstrained transmission is analyzed through experiment and CFD simulation. It is found that the interaction between laundry and transmission change the washing behavior and affect washing performance with regard to the degree of freedom. The results obtained in this study can be used in developing new washing machine transmissions and make them more robust.

This paper is to explore technological forecasting methodologies and their application to military R&D programming. Among a number of forecasting methodologies, eight frequently used methods are explained. They are; Delphi method, analogy, growth curve, trend extrapolation, analytical model, breakthrough, normative method, and combined method. Due to the characteristic situation of a developing country, the application of technological forecasting to the Korean military R&D programming is limited. Therefore, only two forecasting methods such as Delphi and normative method are utilized in the development of a decision model for the military R&D programming. The model consists of a dynamic programming using decision tree model, which optimizes the total cost to equip a certain military item under a given range of risk during a given period. Some pitfalls in forecasting methodologies and of the model are discussed.

Flow rate, watertable and selected water quality of 2 small rural streams and 6 observation well located in Kangwon-do, Korea, were monitored land use of the watersheds was investigated to describe the trend of stream water quality for 2 years and groundwater quality for 1 year. Water qualities were analyzed with respect to BOD, SS, T-N, Nitrate, T-P and E-coli. Stream water quality and gorundwater quality directly concerned with the amount of rainfall and paddy fields. but water quality of watersheds is existed with other factor. Therefore, We have to continued monitoring and developing the best management practice.
