This survey is to investigate the effect of plants and waterscape facilities on the thermal indoor environment and to provide basic data for proper plant cultivation to enhance indoor landscape. The survey of the measure of comfort on the indoor environment for the residents of Taegu shows that the measure of comfort on the thermal-environment, which consist of temperature and humidity, has more negative responses than the measure on lighting . are . sound environment, which consists of air freshness, lighting condition and sound environment. The experiments on the effect of the amount of leaves and the distance of plants on the indoor thermal-environment are made. The experimental results illustrate that, as the capacity of a plant becomes greater and the distance from the plant shorter, the falling effect of temperature and the rising effect of humidity on the top of the plant are taken higher than on the side of the plant. When the same amount of leaves is set up, the distance range of the rising effect of humidity becomes wider than that of the falling effect of temperature. The investigation of the effect of waterscape facilities on the indoor thermal-environment shows that temperature and humidity of the space with installed waterscape facilities are lower and higher than without facilities, respectively.

This research is to investigate the effect of the improvement of investment environments with investment incentive on Korean national economy by looking into the foreign investment support system in Korea. To this end, first research model was set up based on our literary study and case study was conducted on 150 foreign companies that were located in industrial complex for foreign companies, received the tax benefit and government subsidization. And it was found that even though the foreign companies were contributing to the national economy in general such as in the area of production, export, employment, development of technology, there was no significant contributory difference between the investment incentive beneficiary and non-beneficiary foreign companies. Therefore it deemed reasonable to reconsider the way Korean government supports foreign companies in Korea and to reinforce foreign companies' relevance to national policy agenda with additional incentives to foreign companies located in comparatively less developed areas. As a way to promote foreign investment, promotion of investment infra such as improvement of follow-up services, openness to foreign investment, industrial deregulations in capital area, revitalization of free economic zone, efficient system to promote foreign investment and the reinforcement of public relations were considered necessary, especially the upgrading of economic structure and the integrated management of domestic and foreign investors deemed necessary for the optimal distribution of the industries.

The purpose of this study is to assess the residential satisfaction of no-charge welfare facility for the elderly, and to examine the effect of the integration with pay-training institute on residential satisfaction. The data were collected from staffs and fifty one residents of welfare facility by interview and questionnaire. The statistical analysis was conducted to identify the residential satisfaction. A half of the elderly were aged over seventy five years old, eighty four percents of them were female, and seventy seven percents of them were non-educated. Forty two percents of the elderly considered themselves to be unhealthy, but the ADL data reveals that they are relatively healthy. The most of residents are highly satisfied with whole welfare facility. But, the level of satisfaction on the bathroom, the storing space, the cooking table and the benches were relatively low. These dissatisfactions can be solved by the expanding of the storing space, setting up of a common washing room and electric cooking stove, and the increasing of the number of benches. Also, it was recommended for the elderly to set up the Ondol-style rest room with the western style rest room. The level of satisfaction on the attached training institute with no-charge welfare facility for the elderly were high. This has positive effect on residential satisfaction of the elderly. Therefore, the community integrated welfare facility can be the alternative plan for the enhancement of residential satisfaction and quality of elderly life.

The use of fly ash in construction materials is increasing worldwide due the various advantages of using it, such as to produce durable concrete, or to use less cement and thus lower carbon dioxide emissions. The quality of fly ash is often determined by loss on ignition value (LOI), where an upper limit of LOI is set in each country for quality control purpose. However, due to many reasons, production of high LOI fly ash is increasing that cannot be utilized in concrete, ending up in landfill. In this study, the effect of fly ash use in cementitious materials on nitrogen oxides adsorption is examined. In particular, the effect of using high LOI, and thus high carbon content fly ash on nitrogen oxides adsorption is investigated. The results suggest that the higher carbon content fly ash is related to higher nitrogen dioxide adsorption, although normal fly ash was also more effective in nitrogen dioxide adsorption than ordinary portland cement. Also, higher replacement rate of up to 40% of fly ash is beneficial for nitrogen dioxide adsorption. These results demonstrate that high carbon fly ash can be used as construction materials in an environmentally friendly way where strength requirement is low and where nitrogen oxides emissions are high.

In this study, we individualize the clauses to sort out the troubled ones, draw up a interrelation model in order to visually organize the relations, and finally, suggest the desirable application idea. The interrelation model suggested in this study has been made based on the matrix method. On this matrix, we arranged the environmental factors on horizontal and vertical axis, and when we describe the relation of each factors, we set the horizontal axis as the base and divided the content into three grades : Fine, Medium, and Poor. In addition to that, we expressed those three grades into numerical value like 3 points for Level Fine, 2 points for Level Medium, and 1 point for Level Poor and then, we converted this numerical values into index numbers. We could classify the index numbers such as AS, PS, Q-index, P-index. AS is an index numerically shows the degree of giving environmental effect, PS is an index numerically shows the degree of receiving environmental effect, Q-index is an index shows the aggravate degree, and P-index shows the relation degree. The Q/P-index with large numbers has considerable effect on the environmental system, while the small numbered Q/P-index barely effect on the environmental system. Moreover, we classified the environmental factors into 5 levels(I~V) according to the relations between the Q-index and P-index. Level I is less affected by the environment and has more giving effect, while Level V is more sensitively affected by the environment and has more receiving effect, which we considered important. Therefore, we could come up with the result that if we consider the each level of factors when we evaluate the EIA, the result would be far more accurate and reliable since it contains mutual relation aspect of EIA. The suggested interrelation model in this thesis is presentable as one of those scoping system. We highly believe the need of scoping system in EIA and suggest the interrelation model as the alternative idea for scoping system.

Purpose: This study examined the effects of the right or left knee lift during push up plus in the quadruped position on the serratus anterior (SA) muscle activity. Methods: Twenty-one subjects (male 11, female 10) performed the quadruped position on push up plus. The muscle activities of the lower trapezius (LT), SA, and upper trapezius (UT) were measured by surface electromyography. Repeated measurements of one-way ANOVA were performed for statistical analysis of the data, and the criterion for statistical significance was set to p<0.05 and comparative analysis of the UT and SA ratio using a Paired t-test. Results: The right SA increased the muscle activity of the right knee lift during quadruped position push up plus (p<0.05). In particular, the right SA muscle activity was higher than the left. In addition, comparative analysis of the UT and SA ratio to the right knee lift during quadruped position push up plus was performed (p<0.05). The right was found to be a significant statistic compared to the left, but the left SA increased the muscle activity of the left knee lift during quadruped position push up plus (p<0.05). The left SA muscle activity was higher than right. In addition, comparative analysis of UT and SA ratio to the left knee lift during quadruped position push up plus was performed (p<0.05). The left was found to be a significance statistic than the right. In addition, the interaction effect between the groups showed significant differences (p<0.05). Conclusion: Knee lift during push up plus is recommended for the selective activation of a research exercise protocol of one side of the serratus anterior.

본 논문에서는 전산화 단층검사 시 방사선 투과 물질로 방사선량을 흡수하여 피폭 선량을 감소시키는 물질로 알려진 차폐용 Bismuth(비스무스)와 CARE kV(Automated Dose-Optimized Selection of X-ray Tube Voltage)을 사용하여 유용성을 평가하였다. 방사선 감수성이 높은 기관인 수정체(안와), 갑상선, 가슴(유방), 생식기의 선량 감소 효과와 각 기관의 심부선량 차폐 효과를 평가하기 위해 Rando Phantom과 유리 선량계를 이용하여 Bismuth 사용 전 후와, CARE kV의 적용에 따른 선량 감소 효과를 비교해 보았다. 그 결과, 뇌혈관 검사 시 CARE kV을 단독 설정한 검사 방법의 선량이 가장 적었으며, CARE kV 사용여부에 따라 63%의 선량 감소 효과가 있었다. 경동맥 검사 시 CARE kV+Bismuth의 설정 방법에서 선량이 13% 증가하였다. 심혈관 검사 시 CARE kV+Bismuth의 설정 방법이 31% 선량 감소 효과가 있었다. 하지 혈관 검사 시 Bismuth 전체의 설정 방법이 가장 선량이 적게 측정되었지만, 영상 평가 기준에 부적합 하였다. CARE kV을 설정한 검사 방법과는 약 9%의 선량 감소 효과가 있었다.
