The purpose of this study was to examine the appropriate surplus of clothing for a suitable basic bodice pattern of Male Sports Athletes by using the 3D virtual twin and virtual garment simulation system. The results were as follows; 1. By using 3D virtual twin and garment simulation, new bodice pattern considered male sports athletes was development. The basic numerical formula were as follows ; surplus of chest girth=9, surplus of back length=1, armhole depth=back length/4+13, half back width=chest girth/5+2.5, front chest width=chest girth/5+3. 2. Wearing test by 3D virtual garment simulation system was useful to evaluate wearing outline, surplus of clothes and garment space. Also it estimated more highly than existing pattern in silhouette and ease amount, confirming that new bodice pattern is appropriate for the male sports athletes. New bodice pattern was evaluated to allow proper space length of chest and waist. Virtual models production through 3D body scan data, pattern draft and virtual garment digital program were applied to prototypic design method so as to enhance the fitness of ready-made garments. This study is expected to serve as one of important basic data for ensuing studies that may utilize 3D Virtual Garment Simulation System with 2D patterns, and also for future 3D Pattern Production Program development.

전시 공군은 각 지역에 거점부대를 선정하여 해당 지역에서 동원되는 품목별 물자를 인수하고, 물자가 부족한 지역의 거점부대에 잉여물자를 분배하여 전체 부대가 일정한 군수지원 수준을 유지할 수 있도록 계획하고 있다. 또한, 지역 거점부대는 해당지역에 주둔하고 있는 군소 운영부대들에 대한 DC(Distribution Center)의 역할도 담당하여 지역에서 동원되는 물자들과 타 지역 거점부대로부터 인수한 해당 지역 부족물자들을 군소운영부대에 분배한다. 하지만, 전시 동원물자 수송은 물자가 많이 동원되는 지역의 거점부대가 물자가 적게 동원되는 부대로의 분배 및 수송을 책임지기 때문에 동원물자들의 생산특성에 따라 지역 거점부대별 수송부담의 불균형과 다빈도 수송으로 인한 수송 자산(병력, 수송수단)의 낭비를 가져오게 된다. 또한, 공군본부나 군수사령부와 같은 상급부대는 전체적인 동원물자의 분배와 수송을 효율적인 방향으로 조정 통제하는데 대한 어려움이 있다. 본 연구에서는 이러한 어려움을 해소하기 위해 특정지역에 TC(Transfer Center)를 설치하여 물자를 분배하고 수송하는 방법론을 제시고자 한다.

A change in the consumer's surplus was measured in order to evaluate the social benefit to be derived from expanding health insurance to the entire population. The most refined and correct way to measure a project's net benefit to society is to determine a change in the consumer's surplus. Benefits from introducing the health insurance program to the uninsured people can be classified into two elements. The first is the pricing-down effect(E1) which results from applying the insurance price system, which is lower than the actual price, to the uninsured patients. The second effect(E2) is a decrease in actual payment because an insured patient pays only a portion of the total medical bill(copayment). We collected medical price information from the data banks of 93 hospitals, and obtained information of medical utilization by referring to the results of other research and from data published by the Korean Medical Insurance Societies. The total net benefit was estimated as \214 billion, comprising the first effect(E1) of \57 billion and the second effect(E2) of \157 billion. The price elasticity of physician visits is less than that of hospital admissions: however, benefits from the increase in physician visits are greater than those from hospital admissions because there are considerably more of physician visits than hospital admissions. The sensitivity analysis also shows the conclusion that expansion of the health insurance program to the entire population would result in a positive net benefit. Therfore, we conclude that the National Health Insurance Program is socially desirable.

Questionnaire on utilization of colostrum was carried out in 33 farms. Highest milking cow numbers were 20-40 heads in 45.5% of the farms. Calf numbers were 20-40 heads in 39.4% of the dairy farms and 40-60 heads in 42.4% of the farms. The amount of colostrum production per day was 20-30 kg in 30.3% of the farms and 30-40 kg in 30.3% of the farms. Colostrum intake per calf per day was 4 kg in 45.5% farms. Surplus colostrum after intake by calf was farms (85%) was wasted in 67% of the farms. More than 90% of dairy farms recognize an necessity to use surplus colostrum. Selling price of surplus colostrum was below 1,000 won per kg at 15 dairy farms and 1,000-2,000 won per kg at 4 dairy farms. Colostrum collection and use should be done by the dairy farms of antibiotics free. Quality control of colostrum should be done by testing antibiotics, microbacterium, chemical composition, somatic cells and etc. The colostrum is subjected to cool down below $4^{\circ}C$ just after milking and process for the colostrum products.

This study concerns the export-import demands for Korean textile, textile products and clothing products. The result from the practice of study is as follows ; it predicts the constant increase as a result of prediction in the nation's total amount of export-import including the export-import amount of textile, textile-product, and clothing product. It is estimated that nation's textile trade balance will be about U $ 13 billion of trade surplus in every year from 2000 to 2003. Other hand, the trade balance of textile product is predicted about U $ 1.39 billion surplus, so is clothing product about U $ 3.29 billion surplus. Textile ratio is presumed to gradually decrease in aspect of export. Also, the portion of textile export in our national total export is predicted to reduce to 11.61% in the 2003. On the other hand, Textile import ratio will be constantly increased and the portion of textile import in our national total import is predicted to reach to 3.92% in 2003. Textile-product ratio is also estimated to increase in the area of export & 33.12% in 2003. Clothing product ratio is also estimated to increase annually. What with increasing ratio of clothing-product export in textile-product export reaching to total 0.87% within for 4 years(62.96% in 2003, 63.83% in 2003) and what with increasing ratio of clothing-product import in textile-product import reaching to total 6.42%(83.89% in 2000, 90.31% in 2003), it can be said that increase of its import will be much higher than that of export.

This study examines the effects of water shortage on agricultural wages in Northwest Bangladesh. For this study, meteorological data including information on the monthly temperature, precipitation, wind speed, hour of sunshine and humidity of six weather stations have been utilized during the monitoring period from 1985 to 2005. With the objective to analyze water surplus and water deficiency, a simple soil-water balance model and the modified Penman formula were applied to the Northwest Bangladesh. The seasonality of Mann-Kendell trend statistics has been used to identify the spatial variation of water surplus and deficiency throughout the region. For micro level verification of the result, a detailed field survey has been conducted within the study area. The results showed that the values of the potential evapotranspiration estimated by the modified Penmen equation were negative for certain periods. In this instance, the water deficiency of the district of Rajshahi was observed significantly in the period of pre-monsoon and post-monsoon. The field study also verified that because of such deficiency in water, the agricultural scenario of the area was widely influenced which lead to less agricultural production and less economic benefits.

The variable sampling inspection scheme with screening for the purpose of assuring the upper limit of maximum expected surplus loss after inspection has been proposed. In this inspection scheme, it has been assumed that a product lot consists of products manufactured through a single production line and lot quality characteristics follow a normal distribution. In the previous literature with respect to inspection schemes, it has been commonly assumed that lot quality characteristics obey a single normal distribution under the condition that all products are manufactured in the same condition. On the other hand, the production line is designed in order that the workload of respective processes becomes uniform from the viewpoint of line balancing. One of the solutions for the bottleneck process is to arrange the workshops in parallel. The lot quality characteristics from such a production line with the process consisting of some parallel workshops might not follow strictly the single normal distribution. Therefore, we expand an applicable scope of the above mentioned variable sampling inspection scheme with screening in this article. Concretely, we consider the variable sampling inspection with screening for the purpose of assuring the upper limit of average outgoing surplus quality loss in the production lots when the lot quality follows the mixed normal distribution.
