The purpose of this study is the investigation of the physical properties, handle variation of polyester fabrics grafted methacrylic acid. The results are as follow 1. In the case of moisture recovery, MA-g-PET results in an improvement of approximately 4% when the graft ratio reaches 25%, whilst Na-MA-g-PET results in an improvement of approximately 9% when the graft ratio reaches 20%. 2. The static electricity of Na-MA-g-PET, is rarely generated when the graft ratio exceeds 10% . 3. The T.H.V. indicate that the values had deteriorated in the case of MA-g-PET, whilst the N a-Ma-a.PET values demonstrated superiority. 4. The value resulting from the MA-g-PET and Na-MA-g-PET treatment methods are calculated as being 0.0130, whilst the value pursuant to graft ratio is 0.0000.

The main purpose of this study is to analyse economic feasibility of low-carbon-oriented gear for anchovy boat seine. The results of benefit/cost analysis showed that use of the low-carbon fishing gear is economically feasible. Considering the fuel saving and relatively low $CO_2$ emission by reducing the resistance of gear, net present value by such type 1 gear improvement was estimated about -2,490 ~ -1,580 million won with the benefit-cost ratio 0.81~ 0.88. And net present value by such type 2 gear improvement was estimated about 6,540 ~ 7,780 million won with the benefit-cost ratio 1.79 ~ 1.94. Development of lowcarbon trawl gear would render significant contributions to reducing $CO_2$ emission in fishing operations and lead to reduce fishing costs due to fuel savings.

Health benefits from implementing air quality control measures were assessed using the Environmental Benefits Mapping and Analysis Program (BenMAP). BenMAP developed by US EPA is a GIS-based software tool that estimates the health impacts and associated economic values connected with changes in ambient air pollution. Once a set of BenMAP-required data was collected, the health benefits from implementing Seoul Air Quality Management Plan (SAQMP), an official AQ improvement plan for Seoul Metropolitan Area, was assessed using BenMAP. The PM10 concentrations assuming the SAQMP implemented successfully were predicted with the MM5 (Mesoscale Meteorological model version 5)/CMAQ (Community Multiscale Air Quality) model. A PM 10 exposure related premature mortality function was adopted trom a well-known epidemiology study. Economic valuation functions driven from benefit transfer methods were utilized. Through the SAQMP, PM10 concentrations were estimated to be lowered by $15{\mu}g/m^3\;to\;75{\mu}g/m^3$ depending on air quality modeling grids. 5,569 premature deaths (95% CI $3,264{\sim}7,809$ deaths) could be avoided in the Seoul Metropolitan Area. The economic value of the deaths avoided was estimated to $13.2 billion $(95%\;CI\;$890\;million{\sim}$28.2\;billion)$ using the benefit transfer value. BenMAP could be a useful tool for developing effective air quality improvement policy, enabling the policy makers to anticipate the effects of regulatory changes on people's health and the economy.

The purpose of this study is to propose a novel high sensitivity neuro-PET design. The improvement of sensitivity in neuro-PET is important because it can reduce scan time and/or radiation dose. In this study, we proposed a novel PET detector design that combined conical shape detector with cylindrical one to obtain high sensitivity. The sensitivity as a function of the oblique angle and the ratio of the conical to cylindrical portion was estimated to optimize the design of brain PET using Monte Carlo simulation tool, GATE. An axial sensitivity and misplacement rate by penetration of ${\gamma}$ rays were also estimated to evaluate the performance of the proposed PET. The sensitivity was improved by 36% at the center of axial FOV. This value was similar to the calculated value. The misplacement rate of conical shaped PET was about 5% higher than the conventional PET. The results of this study demonstrated the conical detector proposed in this study could provide subsequent improvement in sensitivity which could allow to design high sensitivity PET for brain imaging.

본 연구는 목록 아웃소싱의 타당성 분석을 시도하였으며, 아웃소싱으로 인해 발생하는 부가가치를 정보경제학에 기초한 직접편익, 가치연결의 효과로 분류하여 분석하는 경제성 분석모형을 적용하였다. 직접편익은 비용절감과 비용회피로 가치연결 효과는 목록 품질의 향상정도로 측정하였다. 분석결과, 목록 아웃소싱의 종합적인 타당성은 입증되지 않았으며, 이는 납품업체들의 전문성 결여로 품질제어를 하는데 사서의 시간이 많이 투입되어 실제적인 비용절감에 효과가 거의 없는 것이 가장 근 요인인 것으로 나타났다. 이렇게 현실적인 타당성이 미흡한 상태에서 목록 아웃소싱을 무리하게 이용할 경우 운영비용의 절감과 봉사기능의 제고라는 기본 취지를 달성하는 것이 불가능할 것이다.

This study was investigated the personal rating reason for preference, and opinion for improvement on the Korean traditional foods. Questionnaire were answered by male and female university students at 8 universities in Seoul and the results are summarized as follows. 1) General trend of subjects showed preference for traditional food in order of nutrition, appearance, taste, economics, and cooking method. While the value of food itself such as nutrition, appearance, taste was rated high, practical side such as economics, and cooking method was not so agreed. Especially female students set as lower value on cooking method. 2) As a reason for rating it low, male and female students answered without distinction that traditional food are laborious and much time is needed for cooking. 3) For the idea of improving traditional food, all students had same opinion that standardized cooking method should be developed for convenient use at home, and secondly, special salestore of traditional food should be promoted. Particularly more male students had the opinion that traditional cooking method should be succeeded to at home than female students. Summarizing some significant findings from the analysis of data, all students prefer traditional food itself relatiovely. But generally they rate it low because traditional food is difficult to cook and there are not so many chances of eating. Therefore, it is regarded that standardized cooking method and promoted special salestore for more chance of eating will activated the interest of young generation, and hence contribute to succession of tradition.

This study investigates the properties of light weight foamed concrete designed with various incorporating ratios of CKD and adding ratios of PS. Test showed that increase of CKD and PS decreased fluidity of fresh concrete, which need more addition of superplasticizer to secure proper fluidity. As for the sinking depth of specimens, using more CKD or PS decreased the value, due to the improvement of viscosity by micro particles of CKD and reduction of air loss by PS. Those methods are very effective to solve the sinking problem of light weight foamed concrete, which has been highly concerned. For the hardened concrete, compressive strength of specimens exhibited that using around 10% of CKD or 0.02% of PS increased the strength value, but decreased when incorporated or added more amounts of that, due to reduction of the sinking depth, caused by filling effect of the micro particle and improvement of the viscosity.

Objectives: Atopic dermatitis (AD) is a prevalent and chronic, pruritic inflammatory skin condition that can influence all age groups. AD is associated with a poor health-related quality of life. This randomized clinical trial was performed to compare the effectiveness of Olivederma (combination of aloe vera and virgin olive oil) or betamethasone regarding disease severity, quality of life, serum IgE and eosinophil count. Methods: Thirty-six AD patients were randomly allocated to topical Olivederma or betamethasone, and were followed for 6 weeks. Results: Total SCORAD severity scores showed significant decrease in both groups, while it was more prominent in Olivederma group (64.5% improvement in Olivederma vs. 13.5% improvement in Betamethasone, p-value < 0.001). Quality of life (DLQI questionnaire) of AD patients was significantly improved after 6 weeks treatment with Betamethasone (22.3%, p < 0.001) and Olivederma (60.7%, p-value < 0.001). Olivederma group showed a significantly lower DLQI score in comparison with Betamethasone treated patients after 6 weeks of therapy (p < 0.001). Improvements in eosinophil count and serum IgE was observed. Conclusion: In summary, this study shows that Olivederma is superior to topical Betamethasone after 6 weeks of therapy with regard to disease severity, quality of life and eosinophil count.
