최근 대체수자원 개발, 도시 비점오염과 물순환 체계의 효율적 관리를 위한 분산식 빗물관리기술에 대한관심이 급증하고 있다. 이수 목적의 빗물이용시설, 치수목적의 우수유출 저감시설, 택지개발사업의 재해저감시설 등 다양한 목적으로 시설들이 도입되고 있다. 그러나 치수용 시설에 있어 설계강우에 따른 홍수량 산정방법을 제외하고는 이수 및 물순환 건전화를 위한 계획, 설계기술은 현재까지도 부족한 실정이다. 특히 이수목적의 경우 집수면의 토지이용 특성, 용도별 사용수량 및 경제성에 대한 검토 없이 집수면적이나 대지면적의 일정비율 이상을 설계하고 있는 실정이다. 본 연구에서는 국내에서의 빗물관리시설 계획 설계를 지원하기 위해 공동주택 빗물관리 의사결정지원 모형(RainCity v1.5 Beta)을 개발하였다. 강우자료는 5분 간격의 설계강우, 시우량 및 일 강우자료를 DB나 사용자 파일로부터 호출하도록 하였으며, 토지이용 특성에 따라 유출계수를 고려한 수문학적 집수면적을 산정하여 적용하였다. 현재 버전은 이수 및 치수용 저류조, 침투통, 침투트렌치, 침투블럭 등 장치형 침투시설과 투수성포장 등 지표면 침투시설을 대상으로 하였으며, 각 시설조합의 설치에 따른 유입/유출량, 침투량 및 사용수량 등 물순환 과정을 모의할 수 있다. 특히 선택된 시설조합은 규모 시나리오에 따라 목표 기능에 맞는 시설규모들을 선정하고, 비용-편익분석을 통해 경제적인 시설규모를 결정할 수 있다. 향후 지속적으로 GUI를 개선하여 사용자 편의도를 높이고, 식생형 침투도랑, 생태연못, 중수이용시설과의 연계 등 기능을 확대할 계획이므로 국내에서의 빗물관리시설의 계획 설계 시 활용도가 높을 것으로 기대된다.

In recently years, occurrences of lightning return strokes have been increased by global worming effect and intensity of lightning impulse voltage and current accompanied by lightning discharges has being strengthening. In Korea, 560 thousand lightning discharges happened in 200S. According to the increasing frequencies of lightning, human deaths and damages to the structure have been increased steadily. Electric fire caused by lightning return strokes due to the breakdown between power line and ground line from the ground potential rise on a process of the lightning impulse current through to the ground. The damages of lightning were occurring at same time in the neighboring areas of the lightning point. In order to protect from the lightning stroke, we made a suggestion to use protection devices and equipotential bonding at the dangerous areas. The analysis results of electric fires caused by lightning would be utilized to investigate and to find accurate fire cause in the fire scenes.

Sea level variability and eddy in the Amsterdam-Crozet-Kerguelen region of the South Indian Ocean were studied during 1 year(October 15, 1992~October 15, 1993) using multi-satellite data(Topex/Poseidon, ERSl) produced by signal treatement. We found that generally sea level variabilities(>10cm) exist along the Antarctic Circumpolar Current in the area of 35$^{\circ}$~46$^{\circ}$S and especially strong sea level variabilities(20~30cm) were occurred by the effects of eddy due to botton topography in two small area: 49$^{\circ}$-57$^{\circ}$E and 38$^{\circ}$~42$^{\circ}$S, and 58$^{\circ}$ -64$^{\circ}$E and 42$^{\circ}$-44$^{\circ}$S.

Recently, large scale of the damage from the natural disasters are occurring frequently such as Japanese and New Zealand's earthquake. Collecting information quickly and accurately from damaged area is important for effective react in emergency situations. UAV is effective method to collect information because it can fly low attitude and spend small operational costs/time. In this study, collecting data about the UAV regulations are analyzed for effective UAV operation in disaster detection. And Improvement of Regulations were proposed about Problem of UAV Operation. Regulation of UAV for disaster detecting is not exist. But It's possible to classify into Ultra Light Plane. So addition of some clauses like definition, scope and air-borne equipment for UAV will be needed. Also, it is difficult to manage effectively because of process about flight permission, therefore it is need to enact exceptional regulations to solve this problem. More analytical research based on applications of UAV operation for disaster detection will be present improvement of disaster detection and damage investigation.

Recently many different floating buildings are planed and constructed in the sea, river, etc. for active use of water spaces. But many problems are occurred in the process of floating building design, construction and management due to the inadequate legal system. This incomplete legal system has become one of the critical factors which are hampering the invigoration of floating buildings. Therefore this study is to suggest preliminary data and improvement directions through a case study with domestic and foreign examples of appropriate laws and law applications concerning floating buildings. As the results of this study the laws related to floating building have to be revised in the directions of qualifying legally floating building as 'building' but not 'ship', designating 'special zone' for floating building site, and applying the established 'building licensing procedure' to floating building also.

This study is for a small sized library to expand the functions of public libraries in the community. This study aims to encourage local residents utilizing information and public libraries by opening parted facilities to public and naming it a substitute. It is expected to contribute to richer welfare system. In detail, the study discusses progression of the small sized library as well as budgeting and hiring staffs in Committee on Library and Policy. However, there is limitations in terms of capabilities because school library is different from public library target users, space, unit plans. Therefore, this study investigates a small sized library as a function to find out type, plan, and space availability and size of ideal open school library.

With the increased demand on housing quality and effective urban redevelopment, a new paradigm in reconstruction project is in need. Especially, the Urban and Residential Environment Improvement Law which initiated on July 1, 2003 has become a significant turning point. This code is expected to function as a consistent and systematic measure. This study will examine the code's major concepts and methods to progress reconstruction projects effectively. The application of construction management is examined carefully since the new code requires renewal project consulting firms to function as a professional complement rather than simply perform administration work, as in the past. Also, construction managing methods that can be related to renewal project consulting are examined and speculated. Lastly, methods to improve efficiency in reconstruction projects are introduced through case study and analysis on applicability and expected results.

The goal of this study is to identify the new Architectural type of house and Landscape design pattern of the collective housing area in American garden city, Midlothian near Richmond of Virginia. I had been surveyed old houses of the Virginia and new single family houses and landscape design style of Mariners village to find a different style of houses and lots. The Richmond, capital city of Virginia, is surrounded by five suburban areas and counties. One of them is the Chesterfield where it has main street of Midlothian garden city. The city of Midlothian has a function of residence area both to stay in the forest garden and to go to downtown office of Richmond. There are a lot of collective housing area out of the capital city. I surveyed house form, lots, and site design pattern of the Mariners village in Midlothian. The community of Mariners shows a particular characteristics and harmonious pattern of suburban residence area in a view point of new project. There are three results of this study as follows: First, the types of house in suburban garden city, Midlothian, are focused on vernacular Colonial style with country house, traditional house, and front gable house form which are an unique new American single home. Second, the landscape design of this collective housing area, the Mariners village, has a unity view of residence community, harmony between house and lots, and a sensitive cul-de-sac pattern and loops type with rational land using based on the forest topology. Third, the Mariners village shows that the design concept of landscape architecture has to consider of traditionalism, naturalism, and living condition of residents.

The useful practical land shall be reserved when an artificial land covers the railway and road. However, the problem is that since the artificial land places directly on the top of noise sources likely on the railway and road there will arise the weak points, noise and vibration. On this study based on creating the artificial land on the top of a railway vehicle base and placing a tenement on that land, it was comprehended the noise influence from the railway car through the simulation. In order to secure the input value for the simulation, at first measured the noise condition of the railway station building and the railway vehicle base. The output value for the railway station building (place A) was around (53.6~57.6) dB(A), the equivalent continuous sound level for an hour, and for the railway station building (place B) it was around (63.7~68.9) dB. The maximum outdoor noise of the tenement on the artificial land was measured as 64.1 dB(A) under the fixed condition on the simulation modeling. The built purpose of placing the artificial land to prevent the noise influence from the railway met the expectation to be less influenced on the tenement. Rather, because of placing the artificial land the noise level on the lower space could be increased so there requires having a noise control.
