The production of greenhouse horticultural products in the east region of Kyungnam province is now increasing, though the productions of other argicultural sectors have been rapidly decreasing. However, as the agricultural market lies under the big pressure of the WTO system having a goal of free trade of all commodities, greenhouse horticultural farming in the region also meets with many new problems. To identify problems and prepare development strategies of the greenhouse horticultural farming for the easten Kyungnam region, 10 villages in Kimhae, Yangsan and Miryang areas were selected as sample areas and 204 greenhouse vegetable or floriculture farms were surveyed using prepared questionaires during March-April 1995. From the analysis of the regional survey results, the following proposals are suggested for the development of regional horticultural farming : 1) There were still old-fashioned greenhouse facilities such as tunnel-type vynil house, no heating system and man-power watering. Greenhouse facilities should be modernized and automated in order to overcome the severe labour shortage problem constraining the increase of the greenhouse farming size and the enhance the degree of the commodity value by uniform quality control and year-round production. The money for the modernization and automation of greehouse facilities ned to be supported by the central government, because farmers lack the ability to fund the investment. 2) Not many farmers visited agricultural extension officers to obtain cultivation techniques of greehouse horticulture farming, because extension officers lack the manpower to help solving the greehouse farming problems. Agricultural system should be adjusted to the changing agricultural production structure. Extension manpower specialized in greehouse horticultural farming need be increased and located in the regional extension offices. 3) The major reason of farmer's pessimistic prospect for the future of greegouse horticulture was the possibility of overproduction of some horticultural products. To avoid the overproduction, new entrants to the greenhouse horticultural farming of products already culticated extensively should be limited and the government support must be given to the existing greenhouse farms and major production areas. 4) Local goverment, associated agencies, and farmers should work hard cooperatively to increase the export of horticultural products especially to Japan, the largest importer of agricultural products in the world. Local governments and associated agencies can provide informations related to the export market and provide the fund for the facilities of standardization of export products. Farmers must observe the export contracts, even though the domestic price exceeds the export price. 5) Collective marketing activities of greenhouse products were found to be mainly limited to transportation and handling of sales revenue. Central and local government should support the formation and collective activities of cooperatives of specilaized producers to enhance the bargaining power of farmers. 6) The role of local government should be increased. They should actively participate in the orientation of regional greenhouse farming and play an important role in the marketing of regional greenhouse products.

The purpose of this study is to provide framework for understanding university students' dental services utilization. In this paper Andersen model is applied to the analysis of dental services utilization. This model consists of predisposing, enabling, and need components that describe a person's decision to use dental health services. Questionnaire surveys were conducted for 521 university students. The number of independent variables used in the analysis was 36 in total, ie 25 predisposing components, 8 enabling components, and 3 need components. For statistical analyses of collected data, the multiple regression and the path analysis were adopted, The results obtained were as follows; 1. The proportion of student' dental visits was 41.5%, and the average of the dental visits was 2.33. 2. The purpose of most important recent utilization was dental caries treatment in university student. Also 4.4% of student visited dental clinic for oral disease prevention. 3. The amount of variance of the Andersen model for university student's dental visits was 16%. And of predisposing, enabling and need factors, which are components of the Andersen model, the need factors showed the largest amount of variance for university student's dental visits. 4. Number of restricted activity days caused by oral disease, having a regular dental care, socioeconomic status and perception on oral disease prevention were found to have significant major effects on dental services utilization of university student. Number of restricted activity days was most important factor affecting dental services utilization of student.

This paper describes maximum torque drive of a vector controlled induction motor. As the instantaneous value of the stator current must be controlled to accomplish the superior vector control characteristic, the current controlled PWM transistor inverter with hysteresis controller is adopted. At steady-state, since the developed motor torque is proportional to the product of the flux and torque component, the motor output torque becomes maximum if the two components are equal. The system block diagram is suggested for maximum torque control. The superior characteristic of the proposed system is verified with digital computer simulation.

독일의 사회적 시장경제 : 이론적 기초와 실제 Its Theoretical Basis and Empirical Facts

The Social Market Economy has been regarded as a typically Gelman model of capitalism contrived to make possible rapid economic recovery after the catastrophe of the Second World War, a model of capitalism that put greater emphasis upon social objectives than the Anglo-Saxon model of capitalism. Recently discussion of the Social Market Economy has become a matter of contemporary relevance not only in the former Soviet bloc countries, but also in Korea. It is believed by many to be an economic formula that might be useful to bring about the rebuilding or restructuring of economic systems that is needed. Nonetheless, because of the addition of the adjective 'social', quite what the Social Market Economy might be remains more or less an enigma. What is the Social Market Economy? What does it really mean? Is there only one kind of Social Market Economy? If not, what kinds of Social Market Economies are there? To investigate these questions, this paper begins with an introduction into various meanings attached so far to the word 'social', and then examines historical necessity to come up with a new economic system known as the Social Market Economy that combines freedom of market with social responsibility. From the beginning, however, this combination bears a dilemma in itself. On the one hand, the concept of the Social Market Economy means that certain limits are set to the free market by social elements. On the other hand, there is always the danger that the practice of social policy reduces the performance and functional order of the market and the success of the whole Social Market Economy. Therefore it is necessary to review the results of economic and social policy taken by successive leading political parties to realize the concept of the Social Market Economy and compare the theoretical basis underlying the respective policy measures. The paper concludes that there are at least two different kinds of the Social Market Economy: SME1 adopted mainly by the CDU and SME2 deformed and espoused later by the SPD and draws some lessons from German experience for Korean economic and social policy. In a nutshell, the difference between SME1 and SME2 may be epitomized as follows: <Table 3> ◁표 삽입▷(원문을 참조하세요)

Solving buoyant surface jet, the most important problem is the expression of turbulent transport. In this study, the compatibility of boundary layer approximation of k-ε model which has been applying to predict the turbulent transport in buoyant surface jet are considered. The results which has been comparing the computations of boundary layer approximation equations and full equation with experiments showed. As the result of this study, the hypothesis of boundary layer approximation does not express the transport by mean buoyancy in buoyant surface jet exactly, the hypothesis of boundary layer approximation is not valid for simulation of buoyant surface jet with k-ε model.

This study was conducted to investigate the effect of soil compaction, the changes of optimum soil moisture content and maximum dry density in accordance with each weight of 3 rammers and soil types. The results obtained were as follows; 1.According to a change in soil consistency, the increasing ratio of maximum dry density to the change of optimum soil moisture content by rammer weight was appeared in the following order: Rammer II> Rammer III> Rammer I in A and B samples, but in C and D samples: Rammer III> Rammer II> Hammer I. 2.In accordance with rammer weight, the lighter the rammer weight in A and B samples and the heavier the rammer weight in C and D samples, the larger was the increasing ratio of maximum dry density in each sample. That is, it was desirable to compact with lighter equipment in purely cohesive soil, whereas compacting with heavier equipment was good in cohesionless soil. 3.By rammer weight, the larger soil moisture content, the larger was the decreasing ratio of optimum soil moisture content. 4.In the relationship between compacting energy and optimum soil moisture content and maximum dry density, the lighter the rammer weight, the larger was the increasing ratio of maximum dry density and the decreasing ratio of optimum soil moisture content. The lighter the rammer weight, the larger was the effect of soil compaction and the less was optimum soil moisture content in case of over certain compacting energy, but in case of below the compacting energy, the heavier the rammer weight, the larger was the effect of soil compaction and the less was optimum soil moisture content. 5.In case of standard compacting energy, the heavier the rammer weight, the larger was maximum dry density and the less was optimum soil moisture content.
