This study examines the issue of space management of university facilities by an assessment model as part of efforts to deal with the crisis of universities. To this end, the study addressed efficiency issue and structural problems using assessment model factors, with the aim of figuring out legitimacy and allocating methods for this purpose. Selected model factors included utilization ratio, residual ratio, vacancy ratio, and occupancy ratio, while for the latter, we investigated into the present situations of space use, focusing on construction, design, and living dimensions. As a result, the study suggested that in the future universities will resort to extension and rebuilding or new building for their facilities. To ensure space efficiency without conflict, we should follow legitimacy of space allocation and composition, building quality university facilities, creating quality environment, preventing tuition from rising or Improving welfare to keep pace with the new era.

Free-form blades are widely used in different industries, such as aero-engine and steam turbine. Blades that are damaged during service or have production deficiencies are usually replaced with new ones. This leads to the waste of expensive material and is not sustainable. However, material and costs can be saved by repairing of locally damaged blades or blades with localized production deficiencies. The blade needs to be further machined after welding process to reach the aerodynamic performance requirements. This paper outlines an adaptive location approach of repaired blade for model reconstruction and NC machining. Firstly, a mathematical model is established to describe the localization problem under constraints. Secondly, by solving the mathematical model, localization of repaired blade for NC machining can be obtained. Furthermore, a more flexible method based on the proposed mathematical model and the continuity of the deformation process is developed to realize a better localization. Thirdly, by rebuilding the model of the repaired blade and extracting repair error, optimized tool paths for NC machining is generated adaptively for each individual part. Finally, three examples are given to validate the proposed method.

Our society is changing into the society of knowledge and information since the advent of 21st century. This may require that schooling need to have a new paradigm. Korea has already entered into the aging society with the help of various population control policies such as birth control from 1960s, and is expecting to go into the so called ultra- aging society. Elementary and middle schools have been facing the rapid decrease in the number of students since the mid-1980s, which high schools are now confronting with. The present study investigates how to effectively utilize extra classrooms at schools. The present study offers eight basic directions that may help establish the utilization planning of extra classrooms. One direction is offering an appropriate space utilization environment, another is to present a plan for having special classrooms. Others are having multi-purpose classrooms, management on the unified rooms for library and audio-visual teaching, securing facilities rooms for the school staff. And others are the planning of the diversion of living space for improving sanitation and the provision of meals, the necessity of the extension or rebuilding of school buildings for other uses according to school development schemes, the utilization planning for community residents to which each school belong.

Industrial Complex in Ulsan is one of the most important areas in the nation. It includes ship building, automobile production, petroleum industry, non-metalic industry, and related industries. However, water for drinking and industry use has been and will be short seriously. Thus available drinking water sources were searched. By rebuilding the two existing dams 20m higher than the present levels, $500,000m^3/day$(for 200days) of water sources may be produced. Additional volume of $13,000m^3/day$(for 200days) can be obtained by a number of small dam construction in the vincity area. Underground water of about $50,000m^3/day$ may also be available. The total of $680,000m^3/day$ could be produced in Ulsan area, which is enough for the population of 1,200,000 in Ulsan area even after year 2011. This newly searched volume of water may be free from pollution. Raising the dam levels may also prevent Ulsan city from chronic flooding problems. Additional advantage is that as much as the newly developed water resources can be supplied to the industrial complexes.

As the population of the elderly grows, the prevalence of osteoporosis and its related fractures will increase in both men and women. The etiology, preventive and curative strategies of male osteoporosis are relatively unknown and understudied in comparison with those of female osteoporosis. Even currently approved therapies, e.g. bisphophonates, parathyroid hormone, and testosterone for male osteoporosis are in need of further investigation to test their safety and efficacy. Isoflavones which are found in soy have been shown to positively affect bone by stimulating bone formation while concurrently slowing down bone resorption. These observations mainly come from studies that have employed women or female animal models of osteoporosis. Therefore, there is a need to explore the role of soy and its isoflavones in preventing bone loss or rebuilding bone utilizing men or animal models of .male osteoporosis. From the review of existing literature it is too early to state the extent to which men with osteoporosis can benefit from consumption of soy or its isoflavones. In this review, the efficacy of soy and its isoflavones as alternative and/or adjunctive treatment for male osteoporosis will be discussed.

The rebuilding or redevelopment of buildings in the Readjustment Project District is generally built high-rise buildings. It sometimes makes our residential area to be uniform in height and disharmony with surrounding houses and infrastructure. Then this research examines the landscape effects of the height of buildings built using landscape simulation on hillside and level ground. We suggested that it was desirable for a land readjustment project district to be managed by District Plan and Development Density Controlled Area. In addition, a consideration for the introduction of Average Floors is needed to mitigate the uniform and disharmony with surroundings.

Purpose: Hook nail deformity is caused by inadequately supported nail bed due to loss of distal phalanx or lack of soft tissue, resulting in a claw-like nail form. A composite graft from the foot bencath the nail bed gives adequate restoration of tip pulp. Methods: From September of 1999 to March of 2004, six patients were treated for hook nail deformity and monitored for long term follow up. Donor sites were the lateral side of the big toe or instep area of the foot. We examined cosmetic appearance and nail hooking and sensory test. The curved nail was measured by the picture of before and after surgery. Results: In all cases, composite grafts were well taken, and hook nail deformities were corrected. The curved nail of the 4 patients after surgery were improved to average $28.7^{\circ}$ from average $55.2^{\circ}$ before surgery. The static two point discrimination average was 6.5mm and the moving two point discrimination average was 5.8mm in the sensory test. Conclusion: Composite graft taken from foot supports the nail bed with the tissue closely resembling the fingertip tissue, making it possible for anatomical and histological rebuilding of fingertip.

It is an essential prerequisite to use exact botanical origin of crude drugs for a therapeutic effect. The botanical origin also affects the standard for quality control. During the past decades, Korea, China and Japan have developed individually their own official compendia for crude drugs to tune with the times. This study was accomplished to offer basic data and appropriate suggestions to rebuilding the botanical origins of crude drugs in Korean official compendia according to international harmonization. For this, the botanical origin of crude drugs in official compendia of these three countries were compared based on the scientific name internationally accepted. As results, there were five crude drugs defined as plants or animal of which family were different. Fourteen crude drugs showed the botanical origin of different genus and eighty eight of different species. In addition, usage part and collection season differed in twelve and four crude drugs, respectively.

For rebuilding and managing fish stocks and fisheries, the biological and socioeconomic evaluations on fisheries management regulations are important. This study aimed to estimate the economic effectiveness of different mesh sizes in the yellow croaker gillnet fishery. In particular, by comparing economic effects of mesh sizes, 50mm and 52mm, it aimed to provide the economic validity for increasing mesh sizes. Analytical results showed that the fishing revenue was higher in the vessels using a mesh size over 52mm than that in the vessels using a mesh size less than 50mm. In addition, the effect of fishing cost reduction was also larger in the vessels using a mesh size over 52mm than that in the vessels using a mesh size less than 50mm.
