Waste disposal problem is one of the most important social welfare indicators in urban area, because the volume of waste generated from urban area is remarkable. So far most waste of Seoul has been disposed at landfills. However, this landifill disposal method is confronted with several difficulties in recent. As public concern on environmental problem increases and autonomy system is settled down, local community people of the landfills refuse to receive the waste produced other places any more. It brought reginal confliction problem between waste sending and receiving by refusing to accept waste from certain region. Furthermore, it is difficult to find another place to fill up the waste, while the existing landfiis is reached at the limit in the near future. In terms of environmental aspects landfill method is not the best way to dispose waste. It contaminates the soil and ground/underground water by leaking water containing many serious pollutants as well as offensive oder. In terms of equity, this waste disposal method is not fair. Environmental pollution causes damage to residence near to the landfills, while the waste produced other places. In order to satisfy the equity aspect, the waste generated a region should be disposed within the region. Incineration of Waste has been provided as the alternative. Government plans to construct waste incinerator in every anatomy, so the waste produced by local community is disposed within their local autonomous area. However, the location decision is not easy, since waste incinerator is one of the facilities to the community people. We can not apply the existing location models for this problem, because they show strong NIMBY phenomenon for the location. The location of waste incinerator should be determined very carefully with consideration of various location factors and criteria. This study proposes a methodology for determining the location of the waste incinerators by utilizing GIS, which is a power research tool for location decision where various geographical factors related. We drive the location factors which should be considered in the determination of waste incinerators. They involve environmental, socio-economic, and institutional factors. In first, we eliminate the area which is located within the environmental location criteria such as slope, fault line, distance to river, and then eliminate ares which is conflict with the social and institutional criteria.

목재의 조직, 물리, 역학적 특성은 토양조건과 기후변화 등의 환경적 인자에 의해서도 바뀌게 됨으로 남부 세 지역의 임분 특성이 목재의 재질특성에 미치는 영향과 지역별 조직, 물리, 역학적 특성 등을 비교 검토하였다. 경상도, 전라도, 제주도의 졸참나무임지에 대해 임분 특성과 목재특성을 평가 분석하였는데 이들 간에는 대부분 높은 상관관계가 나타났다. 남부지역의 졸참나무는 온대에서 난대로 기후가 변화하는 난대 지역의 산림자원으로 본 목재재질특성 분석결과 유용한 산림자원으로 활용할 수 있을 것으로 생각된다.

최근 GIS의 보급이 증가하고 공간 데이터 사용자의 요구수준이 높아짐에 따라 웹기반 GIS에서는 단순히 공간 데이터를 지도화하는 것뿐만 아니라 다양한 공간분석과 프로세싱을 통해 공간 정보 및 지식을 효율적으로 제공할 필요성이 제기되고 있다. 또한 공개 GIS 소프트웨어의 발전은 이러한 웹 GIS의 요구를 실현하기 위한 기술적 토대가 되어가고 있다. 본 연구는 공개 GIS 소프트웨어인 GRASS를 이용하여 래스터 데이터의 지도대수 연산을 수행하는 웹 분석 시스템을 구축하는 것을 목적으로 한다. 웹에서의 데이터 분석 방법은 래스터 데이터 처리 시 널리 사용되는 지도대수로 하였으며, 중첩분석에 필요한 가중치는 AHP로 계산하였다. GRASS 기반의 웹 분석 시스템을 구축한 후, 강수량, 표고, 경사각, 경사방향, 토양의 래스터 레이어를 이용하여 산사태 위험도 분석을 시범적으로 구현하였다. 웹과 GRASS의 연동을 통해 지도대수뿐만 아니라 다른 공간분석도 가능할 것으로 기대된다.

Since Industrial Revolution, the sudden industrialization and population explosion have brought about a serious environmental pollution on the air of the earth, the quality of water and the soil, and the greenhouse effect by the destruction of the ozone layer and the greenhouse gas, the organism diversity decline, the desertification by the ruining of woods and the overall global environmental pollution such as the contamination of the ocean and rivers have been come to the front. So the new recognition on the environment is being spreaded in construction business and the efforts for certification acquisition of ISO 14000 being followed by ISO 9000 are progressing, Accordingly, with an example of H Company where integration system is built so that it can minimize the efforts and cost at the construction of the management system, operation and management after the fact, this paper shall suggest the practical scheme of 3 steps through a study to integrate both existing quality management system and new environmental management system. As the integration system of the quality and environment which is constructed by this method is executed, the number of the established and managed document is cut by about a third and so the disorder to encounter between these documents is prevented and unnecessary efforts is reduced in constructing a system, consequently the efficiency of the system is accomplished. Also as the dualization of quality management system and environmental management system additionally needs more men and money after certification acquisition, the non-construction of the integration system may give rise to a cause to aggravate the burden of the company and hereafter when a new system is imported, it may be very difficult to integrate the system. This system integration enables a efficient and effective system to be constructed , operated , and managed after the fact.

Frank Lloyd Wright(1867-1959) had the confident concept that architecture should be at home in nature. His architecture was meant to bear an intimate relation to the earth and the sky, and should look as though it began there at the ground and contrasted with the sky. In handling all the details of house design elements, his efforts for being married to the ground was to conceive the void of the sky. This study is to research his thinking process and its development to the earth and the sky, and to analyze how such thought could reflect his houses. The mass of house are divided into three parts such as the foundation or base, body, and roof. These parts are respectively related to the earth and the sky. This study goes on regarding them as an analytical framework. The subjects of study are the Prairie houses in the early 20th century and the Usonian houses after 1930's. As results of this study, the earlier foundation as a platform appeared as a base and water table, and a strong baseline pressed the structures into the soil in the Prairie houses. The direct contact of wood and brick to ground were dominant details after Wiley house(1934). The base was almost invisible to the eye in the Usonian houses. Secondly, the pierlike shapes and delicate friezes of walls were anchored to the ground, and horizontal bands as trims or copings also got close to the earth. These characters had disappeared after the Allen house(1917), all components including exterior walls had been unified with the grid patterns in the Usonian houses. Thirdly, the overhanging cantilever roof had got to the earthbound by the reflection of shadow as well as their evident horizontal. He lowered the roof, lengthened and brought it closer to the ground. In this way, Frank Lloyd Wright intended his houses to be at home in nature. And also he tried to bind the houses to the earth and contrasted them with the sky. The houses would perform their highest function in relation to the earth and sky.

10 years ago, in Sijeon-ri, Dogo-myeon, Asan-si, the existing stream was repaired to develope Mt. Dogo trail and irrigation systems through road expansion pavement construction and small stream repair construction. The trees such as persimmon and willow are eliminated that rowed on both sides of the stream and dredging work to dig the rock and sand have been performed. As a result, wide asphalt road was built, also flood damage worries were reduced. 10 years passed and now, how did local residents think about the stream repaired before and after? Village residents, public officials, and the stream construction engineer were interviewed. Villagers indicated a problems that brook became a place where water peppers were taking over and water was stagnating due to the slow velocity so nothing could live and natural landscape like a wash place and the cascade disappeared, because rock and sand were taken out brought soil into the brook. Public officials and engineers were aware of the problems at the time of the stream. Now that construction is completed after 10 years, Both realistically and budgetary to restoration would be difficult. However, it is necessary to seek for waterfront space which can be restored or replaced by a part of the stream like similarly before. In addition, it is necessary to restore to the progression of a natural stream which connect with stairs(or slope) - small waterfalls - pools - wash place. In this paper, we hope to take a lesson from the Sijeon-ri model and make rural stream construction be prepared with consideration about not only distinct characteristics of specific area but also the opinion of local resident.

Root colonization of biocontrol agents via seed treatment was investigated and a compatible combination, Gliocladium virens G872B and Pseudomonas putida Pf3, in colonizing cucumber rhizosphere was confirmed through the study. Much higher number of fungal and bacterial propagules were detected when two isolates were inoculated together. The presence of Pf3 in root system was greatly helpful to G872B to colonize at root tip. The mechanism of this phenomenon is partially elucidated through the results of in vitro experiments and the observations of scanning electron and fluorescence microscope. Addition of Pf3 cells resulted earlier germination of G872B conidia and increased mycelial growth. And the more number of germinated conidia on seed coat, the more vigorous hypal streching and sporulation on the root surface were observed in coinoculated treatment. The propagules of G872B on the cucumber root when they were challenged against the pathogenic Fusarium oxysporum, were even higher than that of G872B treated alone, and the magnitude of such a difference was getting grater toward the root ip and the population of F. oxysporum on the root was reduced by seed inoculation of G872B. The rhizosphere competence was obviously reflected to disease suppression and plant growth promotion that induced by the given isolate. Green house experiments revealed that the combined treatment provided long-term disease suppression with greater rate and the larger amount of fruit yield than single treatments. Through this study the low temperature growing Pseudomonas fluorescens M45 and MC07 were evaluated to apply them to the winter crops in field or plastic film house. In vitro tests reveal that M45 and MC07 inhibited the mycelial growth of Pythium ultimum, Rhizoctona solani and Phytophthora capsici and enhanced growth of cucumber cotyledon in MS agar. This effect was more pronounced when the bacteria were incubated at 14$^{\circ}C$ than at 27$^{\circ}C$. And disease suppression and plant growth promotion in green house were also superior at low temperature condition. Seed treatment of M45 or soil treatment of MC07 brought successful control of damping-off and enhanced seedling growth of cucumber. The combined treatment of two isolates was more effective than any single treatment.
