도시의 급격한 팽창과 함께 주택부족 현상이 나타나게 되자, 정부는 주택부족 문제 해결을 위해 대규모 택지개발을 통하여 주택보급을 확대시켰다. 이러한 현상으로, 공동주택은 우리나라 전체 주택의 83% 수준을 유지하고 있고, 그 중 아파트가 차지하는 비중은 50%로 꾸준한 증가 추세를 보이고 있다. 이로 인해 아파트의 경우 입주민들의 승용차 보유 증가에 따른 아파트 단지 내 주차공간 부족문제 등 제반 주차 관련 문제가 발생하고 있다. 특히, 주차계획대수 수립 시 교통영향평가의 주차수요예측 중 전용면적을 고려한 주차원단위 산정 방법은 기존 계획보다 세대수는 증가하여도 전용면적이 작아지면 계획주차대수는 감소하는 것으로 나타나, 보다 현실적인 주차원단위 산정이 필요한 실정이다. 이에 본 연구는 공공주택 아파트를 대상으로 현실에 적합한 주차원단위를 산정하고자 한다. 현장조사 및 설문조사를 실시하고, 구득자료에 대한 분석을 수행함으로써, 기존 교통영향평가의 주차원단위 산정 문제점을 도출하였다. 또한, 주차수요예측에 영향을 미치는 요인 선정을 통해 주차원단위 산정모형을 개발하였다. 마지막으로 실제 조사된 아파트 주차원단위 자료를 통해 기존 교통영향평가의 주차원단위 산정과 본 연구에서 제시한 주차원단위 산정모형을 비교 분석하였다. 향후 본 연구에서 개발된 주차원단위 산정모형은 주차장법 기준 정립은 물론 보다 현실적인 주차수요예측 수행에 적극 활용될 수 있을 것으로 판단된다. The rapid expansion of cities led to the shortage of housing in urban areas. The government compensated for this shortage through large scale residential developments that increased the housing supply. The supply of condominium apartments remains above 83% of the entire housing supply, and the proportion of apartments are at a steady increase, at about 50%. Due to the increase, illegally parked cars resulting from the shortage of parking spaces within the apartment complex have become increasingly problematic as they block the transit of emergency vehicles, and heighten the tension among neighboring residents in obtaining a parking space. Especially, the future residents are considered to plan the parking based on the estimated demand for parking. However, the parking unit method utilized to estimate the parking demand accounts for the exclusive use of space, which is believed to be far from the parking demands in reality. The reason for this discrepancy is that, as the number of households decrease, and area of exclusive space is expanded, the planned parking increases. On the other hand, when the number of households increase, and the area of exclusive space is reduced, the planned parking decreases, thus methods to recalculate the parking units based on estimated parking demand is an urgent concern. To estimate the parking units based on condominium apartments, this study first examined the existing research literature, and appointed the field of investigation to collect the necessary data. In addition, field study data and surveys collected and analyzed, in order to identify the problems underlying parking units, and problems regarding the current traffic impact assessment parking unit calculation method were deduced. Through identifying the influential factors on parking demand estimates, and performing a factorial analysis based on the collected data, the variables were selected in relation to the parking demand estimates, to develop the parking unit estimate model. Finally, through comparing and verifying the existing traffic impact assessment parking unit estimate against the newly developed model using collected data, a far more realistic parking unite estimate was suggested, reflecting the characteristics of the residents. The parking unit estimate model developed in this study is anticipated to serve as the guidelines for future parking lot legislature, as wel as the basis to provide a more realistic estimate of parking demands based on the resident characteristics of an apartment complex.

영동지방의 주요 3개 하천의 수질을 조사하고 QUAL-2E 모델을 적용하여 보았다. 강릉남대천은 각 수질항목에서 시기별, 정점별로 큰 차이를 보였으며, 일반적으로 상류의 수질은 하류로 갈수록 생활오수의 유입으로 수질이 악화되는 전형적인 양상을 나타내었다. 양양남대천은 강릉남대천 및 삼척오십천에 비하여 시기별 변이폭이 좁았으며 각 정점별의 수질도 양호한 것으로 나타났다. 삼척오십천은 시기별보다는 정점별 수질차이가 크게 나타났으며 오염된 상류의 수질이 자정작용에 의하여 개선되다가 다시 생활오수의 유입으로 인하여 악화되는 특이한 양상을 보였다. 모델링 결과 하천의 유속, 유량등의 실측 자료가 부족함에도 불구하고 강릉남대천과 양양남대천은 실측치와 예상치가 높은 상관관계를 나타내었다. 또한 이 모델을 사용하여 강릉남대천의 수질예측을 시도하였다. The water quality was monitored and QUAL-2E modelling was applied in three main stream of Youngdong area. Kangnung Namdaecheon was shown to be a typical stream that the downstream water quality was worse than in the upperstream. Water quality of Yangyang Namdaecheon was better than that of Kangnung Namdaecheon and Samchuk Osipcheon. The spatial variation of water quality was greater than the temporal variation in Samchuk Osipcheon: the polluted upperstream water got better in the midstream, but got worse gain in the downstream. Despite of the lack of suitable measurement data, Kangnung Namdaecheon and Ynagyang Namdaecheon showed good relationship between measured and obtained data: however Samchuk Osipcheon, which had many point sources and much pollution load, showed poor relationship. Based on this model, future water quality of Kangnung Namdaecheon was prospected.

Objective : This study was conducted to evaluate the insecurity of employment and anxiety by downsizing and strikes affected job characteristics and psychosocial distress of workers. Methods and Material : This is a longitudinal study of the container terminal workers in Pusan. The company operated downsizing from October to December in 1999 by economic depression. In the result of that, the number of workers decreased into 627 from 662. During that period, a new union was built and it made conflict between employers and employees, so the conflict caused the strikes from February to April in 2000. The first cross-sectional study was performed in February, 2000 and the oneyear follow-up cross-sectional study was performed in February, 2001. Socio-demo graphic characteristics, stress-related behavior, job characteristics and psychosocial distress were assessed with job content questionnaire(JCQ) and Psychosocial well-being Index(PWI) in 200 workers(white-collar: 100 men, blue collar: 100 men) from 662 men in total. Results : In the first study, job strain was high in the whole, but there was no difference between white and blue-collar workers. The level of PWI was very high at 86.67 points and the level of blue-collar workers was higher than that of white-collar workers(p=0.013). In the results of follow-up study, the rate of drinking and smoking decreased as the change of stress-related behaviors. In the job characteristics change, decision authority and physical exertion of the white-collar workers got lower(p<0.05), but social support and job strain didn't have no difference. In the PWI level change, stress level got rather higher(p<0.01), especially, increase of the white-collar workers' stress was big difference from that of the blue-collar workers'. Conclusion : Job stress management programs should be made to reduce stress. And in approaches to management and prevention, excessive physical exertion, shift work and irregular meals and breaks should be considered. Especially, this stress control program should be begun with recognition on conflicts between employers and employees and between employees and employees by downsizing and strikes. And also efforts to reinforce social support should be needed.

In order to find out the runoff characteristics in Nam River Dam basin, hydrological data such as rainfall, water level, and discharge, have been collected and measured. Using the collected and measured data for the study area during 1990-1999, hydrological parameters were estimated. The HEC-HMS(Hydrologic Modeling System) model was used to review the applicability of flood hydrographs and the results of simulation were compared to the observed data and Stroge Function Method for several flood hydrographs in this study. From the results of analysis, the following conclusions were obtained: First, the HEC-HMS model showed better results for the capabilities of regenerating flood hydrographs Second, the fluctuation shape of flood hydrographs for the rainfall distribution concentrated on head have been shown peak time to be relatively short for other rainfall distribution. Third, for forecasting and warning of flood occurrence in future, it is necessary that the existing hydrological data were made good and hydrological data were accumulated more. Also, using the HEC-HMS model to complement the Storage Function Method, it is possible that forecasting and warning flood occurrence is progressive in Nam River Dam.

In order to search an efficient analytical method for analyzing the contents of nutrient salts [total nitrogen(T-N) and total phosphorus(T-P)] in sediments of reservoir, we compared microwave digestion method with autoclave method in sample preparation. The content of T-N obtained by microwave digestion method was lower(approximately 30%) than that obtained by autoclave method. But the content of T-P obtained by microwave digestion method was twice as much as that obtained by autoclave method. The desorption efficiency of T-N and T-P in both methods were good. The reproducibility of measurement results in microwave digestion method was better than that in autoclave method. A considerable amount of both nutrient salts was adsorpted on the sediment of Song-ak reservoir. Depending on the depth of sediment, differences in the contents of T-N were significant. The content of T-N in surface layer was highest. From these results, we recommend the microwave digestion method in sample preparation for analysis of T-N and T-P, because that method shows a higher reproducibility and provides a condition in which both nutrient salts can be simultaneously analyzed. We also suggest that in order to control water quality of reservoir a proper control measurement for nutrient salts adsorpted on sediments was needed.

The lyophilization of the solution extracted from 60 percent of acetone applied to persimmon leaves, the compounding process in accordance with the solution's concentration, and the gel filteration through Sephadex G-50 of biologically activated substances obstructing enzyme activity, such as tyrosinase, xanthine oxidase, and angiotesin converting enzyme (ACE) led to the assumption that polyphenol was the compound serving as biologically activated substances obstructing enzyme activity. Xanthine oxidase involved in pruine metabolism oxidizes hypoxanthine to xanthine and xanthine to uric acid. In the continuous study for natural compound, nine flavan-3-ois have been isolated from the persimmon leaves. The structures of (+)-catechin, (+)-gallocatechin, procyanidin B-1, pyrocyanidin C-1, prodelphinidin B-3, gallocatechin-(4α→8)-catechin, procyanidin B-7-3-O-gallate, procyanidin C-1-3'-3''-3'''-O-trigallate and (-)-epigallocatechin-(4β→8)-epigallocatechin-(4β→8)-catechin were established by NMR and their inhibitory effect on xanthine oxidase activity was investigated. Procyanidin C-1-3'-3''-3'''-O-trigallate showed 94%, 90.69%, 80.90% inhibition at 100(μ)M and inhibited on the angiotension converting enzyme respectively. Procyanidin B-7-3-O-gallate and procyanidin 1-3'-3''-3'''-O-trigallate showed 66%, 63% inhibition at 100(μ)M and inhibited on the xanthine oxidase competitively. Procyanidin C-1-3'-3''-3'''-O-trigallate showed 70% inhibition at 100(μ)M inhibited on the thyrosinase competitively.

The object of this study is to survey water quality of reservoirsin in Asan city. We also suggest some countmeasures for environmental preservation toward sustainable urban development of Asan city. We analyze water qualities (pH, DO, COD, SS, T-P, T-N and Chlorophyll-a) of reservoirs. The level of water quality of small reservoirs is in the range of level Ⅳ-Ⅴ higher than the level Ⅲ established by the Ministry of Environment. Especially, water quality of Sinchang, Youngin and Shinchung reservoirs is worser than that of other reservoirs. Water quality of Asan and Sapkyo lake is the range of level Ⅳ-Ⅴ. As the levels of T-P and T-N are level Ⅳ and level Ⅴ, respectively, eutrophication might be progressed. Reservoirs in Asan city were already serious polluted by inflow of wastewater from residents, animal husbandries and industries. Recently, Metropolitan Area Development Planning(MADP) for Asan bay-area was suggested by the Ministry of Construction. According to this plan, industrialization and urbanization of Asan area will rapidly progress. If sewage and wastewater treatment facilitiesare not provided, water quality of reservoirs in Asan city will be worse. In order to prevent of environment pollution, first, the impact of industrialization and urbanization of Asan area on the environment should be considered at the beginning of MADP. Second, total effluent regulation of water pollution, air pollution and soil wastes, based on the self-purification of the Asan city environment, should be enforced.
