도시에 매설된 상수관망의 노후화와 매설된 주변 환경의 변화로 관 보수와 파괴가 자주 발생하게 된다. 이때 보수 또는 교체를 위하여 상수관망의 일부를 격리하여야 하며 이를 위해서 제수밸브를 차폐해야 한다. 그러나 제수밸브가 격리하고자 하는 영역 주변에 적절히 배치되어 있지 않은 경우 필요한 부분보다 많은 영역이 격리되게 되며, 이는 격리로 인한 피해범위를 증가시키게 된다. 이와 함께 적절치 못한 제수밸브 관리로 인해 제수밸브가 차폐되지 않는 경우 해당 제수밸브 주변에 위치한 제수밸브를 추가로 차폐해야 하는 경우가 발생하게 되며 추가적인 상수관의 격리로 인하여 처음의 상수관 격리에 의한 피해를 증가시키는 결과를 야기한다. 이러한 문제는 제수밸브의 효율적 배치로 감소할 수 있으나 효율적 배치를 위한 선행과제로 현재 설치되어 있는 제수밸브 배치의 적정성을 평가하는 것이 필요하다. 이를 위하여 본 연구에서는 상수관 격리와 제수밸브가 차폐되지 않는 경우를 동시에 고려한 모의방법(simulation)을 제안하였다. 상수관망 전체 대한 상수관 파괴당 평균적인 단수인구로 제수밸브의 적정 분포를 정량화하여 다양한 제수밸브 분포사이의 적정성을 비교할 수게 하였다. 이러한 비교를 바탕으로 새로운 상수관망에서 효율적인 제수밸브 분포가 가능하며 기존 상수관망에 제수밸브를 추가할 경우에도 유용한 결과를 얻을 수 있다.

This study aimed to grasp Feng Shui Geographical Thought appears in layout, Axial symmetry, hierarchical planning, spatial composition and hidden design techniques of Chinese Garden, that is "Xue effect", "Long-Sha effect" and "Shuikou effect", and to study on expression in Landscape Space. The Author selected the Chinese courtyard and the Nets Garden as the object to prove the Layout landscaping techniques; and selected Beijing in Ming and Qing Dynasties and the Forbidden City, A square design in Xuanwei as the object to prove the Axial Symmetrical and Hierarchical landscaping techniques, and also selected the Lingering G-arden and the Gentle Waves Pavilion, Humble Administrator's Garden in Suzhou, and Nanhu Park in Taian as the object to prove the Spatial Composition and Hidden design techniques. The methods of this article is combined Literature survey and Field survey with Case analysis to draw the conclusions as follows: First, "Xue effect" of Chinese Feng Shui Geographical Thought is suitable for the layout of Chinese courtyard and the Nets Garden in Suzhou; Second, "Long-Sha effect" is suitable for the urban planning of Beijing in Ming and Qing Dynasty, and the layout of the Forbidden City, by the city square design in Xuanwei, we can see that it is also suitable for Chinese modern landscape design; Third, "Shuikou effect" is appeared in the Spatial Composition and Hidden design techniques. All of these landscape design techniques are commonly used in China's modern landscape. It has been proved by the analysis of the Lingering Garden and the Gentle Waves Pavilion, Humble Administrator's Garden in Suzhou, and Nanhu Park in Taian.

This study defines three types of public parking for commercial business, cultural tours, sales and market areas. We compared the Santa Barbara parking system with Korean examples for use in urban revitalization with a proper planning strategy based on district-specific public parking. The results are as follows: 1. The layout and location of public parking entrances need to consider the urban grid and linkages. 2. Public parking should place emphasis on respecting a district's character and user convenience. 3. The success of public parking extends to revitalization of pedestrian paths at target areas.

The purpose of this research is to investigate the characteristics of layout of Jinhae's educational facilities from the perspective of space syntactic changes since the era of Japanese Imperialism. The observations that we made in this research are summarized as the following three points. First, most of the educational facilities are located near the integrated space. Axes of roads near educational facilities display similar spatial patterns as those of entire Jinhae. Second, the level of local integration has been rising near the site of elementary schools for the past decades, and the level of local integration near middle and high schools recently began to rise around the new town. Third, the level of integration is strongly related with the levels of local integration, and the locations of educational facilities are also related with the level of local integration. It implies that the locations of educational facilities are determined not by Jinhae's overall street composition but by nearby road composition.

도시의 안전을 위해서 재해 발생시 대응 및 복구와 같은 사후처리도 중요하지만 재해에 취약한 지역을 사전에 파악하고, 예방적 차원에서 이러한 지역들을 체계적으로 관리하는 것이 점차 중요해지고 있다. 본 연구는 대도시 관리차원에서 필요한 방재지도의 유형 중 하나로 화재를 상정하여, 화재위험지역을 선정하는 기준을 설정하고 이 기준에 맞춰 서울시 종로구 창신동을 사례지역으로 하여 화재위험지도를 시범적으로 구축하는 것을 주요 내용으로 한다 화재위험지도성은 방재업무에 있어 지역성에 기초하여 취약지구를 사전에 파악하고 체계적으로 관리하는데 활용될 수 있으며, 나아가 지구단위계획 등의 도시계획업무에서 방재를 고려한 토지이용계획 수립 및 도시계획시설 배치 등에 활용될 수 있을 것으로 판단된다.

This research attempts to consider disasters and calamities in the process of urban planning and road design. It presents a model that copes with disaster response. This model is an integrated system that performs the collective evaluation of roads, shelters, storage reservoirs and evacuation route systems. Consequently, this research attempts to discuss major issues to apply this system to cities.

The purpose of this study is to provide a basis for determining when a school established long term school plans accepted by analyzing the trend of increase or decrease elementary school students 30 years to target of following nine cities, 607 elementary schools in Korea - 4 metropolitan cities(Incheon, Seongnam, Su-won and Anyang), 2 central regional cities (Daejeon and Cheongju) and 3 southern regional cities(Busan, Yangsan and Kimhae) for this purpose. Results of this study are as follows: First, there were overwhelming numbers of type5 among15 types of increase / decrease in the number of students. Second, in comparison with the type of increase / decrease of the number of students by region, the metropolitan area is ranked as type5>type13>type10>type8, in the middle region type5>type11>type10>type13 and in southern region type5>type10>type11>type13>type2. Therefore, there were regional differences in the number of students. Third, the results of the Conflict Model I and Conflict Model II showed that Type1 and Type7 were not needed to be adopted.

최근 기상이변으로 인하여 예측이 어려운 게릴라성 집중호우 등의 증가로 재해 및 재난이 빈번하게 발생하고 있으며, 특히 도시지역에서의 홍수피해로 막대한 인명과 재산피해가 발생하고 있다. 도시지역내로 유입되는 홍수는 다양한 형태와 크기를 가지는 건물과 도로의 배치에 의해 크게 영향을 받으며, 매우 복잡한 흐름특성을 나타내는 것으로 알려져 있다. 도시지역이 조밀한 건물군으로 구성되어 있을 경우 홍수의 대부분은 도로와 교차점을 통해 흐르므로 도시지역 내에서 홍수로 인한 피해를 저감하기 위해서는 도로 교차로에서의 홍수파의 전파특성을 분석하는 것이 중요하다. 교차로는 세 개 또는 네 개의 도로가 대칭 또는 비대칭으로 연결되어 있으며, 일반적으로 교차로에서의 흐름은 유입되는 유량이 상대적으로 적고 도로의 경사가 비교적 완만한 경우 상류 특성을 나타내나 이와 반대일 경우에는 상류 및 사류가 공존하는 복잡한 수면형을 나타낸다. 본 연구에서는 도지지역 내 도로 교차점에서 유입경사 변화에 따른 도로 교차부에서의 흐름특성을 수치모의 결과와 수리실험 결과와 비교하였다. Case 1은 수로의 유입경사가 3%일 경우 도로 교차로에서 수위 및 흐름특성을 수치모의결과와 비교한 결과 조도계수가 0.0086일 경우 RMSE 값은 X축에서는 0.0023, Y축에서는 0.0042로 수로중심에서의 수심분포가 잘 일치 하였으며, 흐름특성 또한 수치모의결과와 잘 일치하는 경향을 보였다. Case 2에서는 검증결과를 바탕으로 유입경사가 3%와 5%일 경우 도로와 교차점에서의 흐름특성을 수치적 방법을 통해 분석하였으며, 유입경사가 변화함에 따른 수면흐름특성을 모의하였다.

Loading zone is necessary to central business district(CBD) due to freight trucks coming into inner city. Currently truck drivers in metropolitan area are forced to illegally park their freight trucks on the roads close to the business facilities because there is no or few loading zones available in the CBD. This situation would bring into traffic congestion and even might block local roads in the CBD. This study reviews the existing improvement plans in city logistics, and examines delivery characteristics related to freight trucks and drivers in Seomyeon, the central downtown of Busan. Also it conducts a location planning for on-street loading/unloading bay using a technical method for arranging loading space. This research estimated the number of parking and stop bays for truck's operation using queueing theory based on truck-service rate and arrival rate, and found locations with the minimum resistance function values for freight movement in arranging on-street loading/unloading bays.

The purpose of this study is to provide a basis for determining when a school established long term school plans accepted by analyzing the trend of increase or decrease elementary school students 30 years to target of following city, 323 elementary schools in Busan - 16 administration zone for this purpose. Results of this study are as follows: First, type 5 occupies 55.4% of the total, followed by the second most, type 10, 21.4%> type 11> type 13> type 15, which is the most urgent object of the student placement plan Can be. Second, the results of the Conflict Model I and Conflict Model II showed that Type1 and Type7 were not needed to be adopted. Third, we can see through the case analysis that the effect of excessive school opening on the decrease of the number of students in the nearby school is serious. Fourth, as a result of analyzing the current number of students in Busan, the number of schools with less than 150 students accounted for 12.4% of the total 323 elementary schools, 30.0% for schools with less than 300 students, and 60.4% for students with less than 600 students. Fifth, when the elementary school student induction rate of urban redevelopment area in Busan was examined, the average induction rate was 0.37.
