        The golf industry is being prospected as a promising leisure sports industry of 21th centry, thinking the rapidly increasing golf population in Korea. But there are many hampering elements in development of golf industry because of the negative recognition and various restriction of the golf. To analyze these problems, this study has the objects. First, to analyze the present condition of Korea golf industry, Second, to choose the subjects hampering the development of the golf industry and to present the developing direction of the golf industry. the conclusion of this study object is ad following 1.The present condition of Korean golf industry 1)The domestic golf filed of November 2001, is 154 places ( membership: 112, public course: 42 ) witch is only 0.24% of the whole Korean population, and it is not enough. These golf fields are too concentrated in Kyungkido, Kangwondo and Jejudo. 2)The golf people who have been the golf field in 2,000 is 12,050,000 people, it is expected to be 22,900,000 people in 2010. The korean golf tourists to abroad is increasing every year but the foreign golf tourist to korea is not increasing. 3)The trade valance of golf goods is recorded as red lettered, golf club and golf parts are the main deficit elements, but golf ball is recorded as black. 2.A task in development of Korean golf industry. 1)The problem of a negative thought to golf. Because too much money is spent playing golf ordinary person thinks the golf as a luxury sports. This problem should be solved by reducing the cost through the various tax relief, by enlarging a ratio of the public course, by controling the negative speaking or report to golf from mass madia. 2)Unreasonable tax system. The taxes related to the golf, at the time of building, opening and using of the golf field and at the time of making and purchasing of the golf goods, are too high charged and it cause many problems. 3)Too difficult permission system. The beforehand process of the golf business, that is the making of business planning, operating course, starting work, is too complicated and take long time of one year. It should be simplified. 4)The problem of the destruction and pollution of environment. The golf field is built harmonizing with beautiful scene establishment and pleasant environment. Thus the problem of environment destruction at the time of building the golf field is not thought to be persuasive. The problem of distribution of agriculture medicine is much more prohibited comparing to the other establishments, we can minimize its harm by the through supervision.

      • 대학경쟁력 제고를 위한 적정교육원가 산출에 관한 연구 - 삼척대학교를 중심으로 -

        金鍾變 삼척대학교 산업과학기술연구소 2001 産業科學技術硏究論文集 Vol.6 No.1

        Full cost of school in a university is measured in this paper to provide an informational base for tuition discrimination policy among schools. Lectures of each school are understood as its products, and students as its clients. Full cost per client is more relevant for purpose than full cost per lectures, since the latter cannot be accepted as a final measure of educational efficiency. The first step is to trace the direct education cost or lecture cost to each school with the inter-school lecture fully accounted. The next step is to distribute indirect education cost to each school. Contribution of schools to the university fund from their external research revenue is regarded as the repayment of a part of the indirect cost which they owe to the university, and thus is subtracted from the school education cost. In the conclusion, it is recommended to discriminate the school tuition on the basis of the direct lecture cost added to a few indirect cost items. By result of educational cost analysis, It may be reasonable that the rise rate of the average tuition in the Samchok National University is decided in level 9.09% in 2001.

        In order to collect the basic data for the production of nodular cast iron requiring wear resistance. the mechanical nature such as structure analysis, hardness, and tensile strength were performed on cast sample by changing residual Mg concentration of cast iron at the range of 0∼0.052% and also the wear characteristics were examined through wear test by changing abrasion speed and final load. As a result, the following conclusions were drawn. The wear amount rapidly accelerates to the maximum abrasion sped of 2.3m/sec in a sample without Fe-Si-Mg alloy processing(residual Mg amount; 0%) by increasing the abrasion speed from 1.3m/sec to 2.3m/sec. As the Mg residual Mg contents increases, the ratio of nodular increases while hardness of a sample accelerates and the wear amount decreases. The maximum point moved to the high speed side in a sample with 0.043% residual Mg contents and the wear amount showed the maximum in 3.5m/sec of abrasion speed while a sample with 0.052% residual Mg contents showed the mechanical destruction wear to 4.3m/sec abrasion speed. The more residual Mg contents are in 0.6-l.1m/sec low speed range of abrasion speed, the more wear amount was resulted while the less residual Mg contents were. the less wear amount showed. Oxidation wear occurs at 4.5m/sec of traveling velocity. Since the wear of matrix structure occurs after wear of oxidized substance in friction caused by oxidized substance, the wear amount shows less than 2.3mg/sec traveling velocity. Therefore, as the residual Mg contents increase, the wear amount decreases. Although the wear amount is large since the traveling distance of destruction wear lasts very long. the residual Mg contents are small and the oxidation wear area becomes long in a sample with low hardness. Since the mechanical destruction wear occurs when the traveling &stances reaches to the end, the wear amount results in very small. The scratches appeared due to abrasive wear in mechanical destruction wear with 2.3/sec abrasion speed while it did not show in oxidation wear although the severe wear occurred. The sectional melting appeared in 5.4m/sec of high speed friction since the temperature of contact point increased more than 1000℃. Scratches are less in the area with low load and if load increase, shoving occurs in wear grooves. In the maximum load, the severe cracking phenomenon can be observed.

        The apartment is one of the representative city housings and it has contributed not only to the solution for the quantitative lack of housing but also to the improvement of a standard of living. But. in case of the permanent rental housing for the lower income bracket in the city. economical efficiency was the most important thing to consider and the planning was relatively focused on the development of a typical plan for an unspecified number of the general public. Therefore unit plans of apartments has been decided by the floor space for the exclusive use. the number of bedrooms and the mode of composition of rooms. As a result. unit plans of the permanent rental housing became fixed and uniform. In apartment planning. not only the various requirements of resident households must be accepted but also economy and efficiency should be considered at the same time. Recently various unit plans has been studied according to varied requirements of resident households and criticism on uniform unit plans. Accordingly. this study analyzed the unit plans of existing permanent rental housing and suggested the planning Data of permanent rental housing in the near future.

      • 분산환경에서 유전자 알고리즘을 이용한 고 가용성 디스크 캐쉬 관리자 연구

        최신형,진광윤 三陟大學校 産業科學技術硏究所 2003 産業科學技術硏究論文集 Vol.8 No.2

        This paper presents the design and implementation of the Disk Cache Manager (DCM). which operates on top of the micro-kernel based distributed operating system for clustering system connected with multiple PC. and enhances the I/O performance of the shared disks. The DCM interacts with different servers through message passing mechanism provided by the micro-kernel. To increase the shared disk I/O performance, the DCM employs a Seven, Disk and a Socid Disk for each physical shared disk. so that it enables efficient data placements for shared disks. The cluster node of the node allocation system provides a good allocation solution using Genetic Algorithms(GA) distributing the parallel modules to the clustered nodes. As an utilization of a certain shared disk is incremented, the DCM enlarges a corresponding cache size. thus increasing the hit ratio of the disk cache. In result. the enhancement of the overall disk I/O performance can be achieved.
