생활수준 향상과 식생활 변화로 인하여 생활용수 소비량이 증가함에 따라 일상생활에서 배출되는 오수의 양도 증가할 것으로 예측된다. 아파트 단지내 오수정화시설 및 하수처리장의 설계를 위해서는 먼저 인구에 근거한 오수량의 발생원단위를 알아야 한다. 이러한 자료는 하수처리의 운전이나 수질관리 계획 수립을 위해서도 꼭 필요한 것이다. 따라서 본 연구에서는 주택공사의 123개 관리소에 2년간의 급수량을 취합하여 거주인구에 따른 급수량을 분석하였고 그 중에 수도권

For efficient development of rural facilities, choice of their optimum locations would be an important issue, however, existing research works concentrated much more an allocation policy of urban industrial complex and public facilities than rural ones. In this study, because agricultural-cum-industrial complex has been the most widely developed representative one of rural facilities, it was selected as a case study facility. As a pre-study to system development, existing governmental location-decision system was checked and interviewing survey carried out to find out on-spot problems. And, being based on literature review and survey analysis results, 4-step optimum locational decision model was developed , formulation of locational goal system, ranking tabulation on components, determination of significance values of components, calculation of component scores. Finally, through the case study works on 3 sites, system applicability was checked, Considering together the simplicity problem of existing guidelines and the interviewing survey results favoring the diversified viewpoints, it would be necessary to develop multifaceted support system for locational decision making. 3-tier classification steps from the higher, middle to lower one were used and their underpinning viewpoints were sorted as on regional development, entrepreneurship, spatial rationality, from which a tentative locational goal system was formulated. Through the expert group checking, final locational goal system was determined having 3 of the higher classification items, 7 of the middle ones, 23 of the lower ogles. For ranking tabulation, 3 types of ranking criteria were arranged which were based on statistical analysis using mean and standard deviation(Type I ), its existence or not 1 good or not(Type E ), and the others(Type E ). From the significance evaluation results, regional development and entrepreneurship aspects were valued much higher than spatial rationality aspect. And, in the middle step, items as spread effects of regional economy, accessibility and social potentialities were highly valued while infrastructural development level and natural condition being low. The application results of the system to 3 case study total. However, the detailed ones differed among study the influencing effects on regional economy, and contrast greater the infrastructural development level. Conclusively, final evaluation values well represented the characteristics of each area. If this system be complemented and applied comprehensively by the successive studies, it would be developed to a general model of locational decision supporting system for rural facilities.

The purpose of this study was to provide basic data of the growth characteristics of the landscape trees for better landscape planting design, construction and maintenance through the prediction of landscape change as time passes by the analysis of survival rate, distribution patterns & increment percent of tree height, width, stem diameter (breast or surface) of widely used six tree species in Seongnam-si Eunhang-jugong apartment housing areas (8 years have passed after landscape planting work). The main results can be summarized as follows: The tree survival rate of Pinus parviflora was the highest rate 89.2% than any other species, but Acer buergerianum showed the lowest survival rate as that of it 35.0%, & that of Picea abies 70.5 %, Metasequoia glyptostroboides 71.6%, Magnolia denudata 38.9%, Acer palmatum was 71.7%. As a whole, the tree survival rate of coniferous trees were relatively high. The tree height increment percent of the deciduous species were relatively high. And that of Metasequoia glyptostroboides was the highest rate 11.61 % than any other species, but that of Magnolia denudata was the lowest rate 5.59% than any other species. According to this results, the increment percent of trees in this apartment areas were comparatively lower than that of each related species planted in nursery area. And this results would be considered when landscape experts do landscape planting design, construction & maintenance. The distribution patterns of present tree size showed a Normal Distribution like any other biological features.

The change of water level at Mokpo Harbour and its adjacent coastal area due to the construction of the Youngsan Estuary Barrage and the Third Land Reclamation Work of estuary barren had been roughly expected. Periodical floods, which occur 2 times per month, are also being observed at the low lying commercial areas near the Mokpo Old Harbor. Although it is said that the highest tidal current component among the tidal current records at the approaching channel to Mokpo Harbor is reduced to 6 kts, because of the esturary barrage, they do not give any precise statement or a deep analysis for the flooding and periodical water level change under certain environmental conditions. Moreover, they never tried the analysis of development plan considering the natural disaster such as typhoon or other extreme conditions. Thus, it is necessary to collect and analyze the data related to floodings, harbor oscillations, currents, and water quality , etc. because of the development considering the extreme condition. Thus, it is necessary to collect and analyze the data related to floodings, harbor oscillations, currents, and water quality, etc. because of the development considering the extreme condition and to evaluate the field observation and measurement, including the numerical model simulation based on the scientific approaches. This study deals the problem of the water level change among the integrated analyses of the coastal area changes. The result can be used for the integrated planning to give a strong foundation and it will contribute to the development of local area.

다량의 대기오염물(SO2, HF)이 배출되고 있는 공업단지 주변에서 재배되고 있는 수도의 생육에 이들 대기오염물이 미치는 영향을 구명하기 위하여 수도의 각종 형질, 수량, 대기중의 오염물 농도, 엽내유황 및 불소함량과 엽피해율을 조사하여 시험한 결과는 다음과 같다. 1. 엽내유황함량과 대기중 아황산가스 농도간에는 높은 정의 상관이 인정되었다. 2. 엽피해율 조사치는 대기오염에 의한 수량감소의 가장 중요한 지표로 이용 할 수 있다. 3. 본 조사지역에서는 아황산가스보다 불화수소의 배출량이 적지만 엽피해의 발생에는 불소의 관련성이 아황산가스보다 높았다. 4 수량형질의 수량에 대한 기여정도는 주당수수가 제일 컸으며, 주당수수는 엽내 불소함량과 깊은 관련성이 인정되었다. 5. 엽내 유황함량은 수량 및 수량형질과 상관성이 인정되지 않았다.
