도시지역에 있어서 변화를 탐지하는 작업은 도시를 효율적으로 관리하는 관점에서 매우 중요한 업무 중의 하나이다. 그러나 최근 들어 도시지역의 건축물이 고층화, 밀집화, 불규칙화됨으로 인해서 오직 정사영상만에 의존하는 기존의 방법으로는 다양한 변화를 추출하기가 점점 더 어려워지고 있다. 이러한 상황에서 보다 정밀한 수치판독을 위해서 경사영상의 활용성이 증가하고 있으며, 이에 본 연구에서는 하나의 피사체에 대하여 동시에 경사 및 수직방향의 영상을 취득할 수 있는 다방향 영상촬영시스템을 이용하여 수치판독을 수행하고 결과를 검토하였다. 그 결과 도시지역의 판독업무에 있어서 다방향 영상촬영시스템의 우수성을 확인할 수 있었다.

One of the most important elements in creating the pleasant residential environment is the wind. For the pleasant residential environment, it is important that the air pollutants are not stagnant but appropriately and swiftly diffused and removed by winds. Especially, the river becomes a main route of wind in the urban core. So, it is necessary to secure the space to circulate the sufficient cool air to this area. But, recently many high-rise apartment complexes have been built along the rivers that have the fine view and pleasant environment. As a result, the cool and fresh air coming from mountains hardly diffuses into the urban core but just flows along the river. Considering the facts above, this study selected types of building layout and kind of land cover as complex or architectural design factors that have an influence on wind environment. Based on the factors, it analyzed change in wind environment according to apartment complex development aiming at the Sinchun area which is Daegu Metropolitan City's main wind corridor. Therefore, when apartment complex development is planned in the future, it can offer basic data for establishing plans for more pleasant complexes. As a result of the analysis, it was shown that the layout type of housing and the building height plan in consideration of wind corridor around the river were pretty effective in increasing the wind speed and circulating the air in the apartment complex. Therefore, if wind corridor is considered when apartment complex development is planed in the future, this study can offer useful information contributing to improve comfort in residential environment in the level of complex building as well as city planning.

A meso-urban meteorological model (Urbanized MM5; uMM5) with urban canopy parameterization (UCP) was applied to the high-resolution simulation of meteorological fields in a complex coastal urban area and the assessment of urban impacts. Multi-scale simulations with the uMM5 in the innermost domain (1-km resolution) covering the Busan metropolitan region were performed during a typical sea breeze episode (4~8 August 2006) with detailed fine-resolution inputs (urban morphology, land-use/land-cover sub-grid distribution, and high-quality digital elevation model data sets). An additional simulation using the standard MM5 was also conducted to identify the effects of urban surface properties under urban meteorological conditions. Results showed that the uMM5 reproduced well the urban thermal and dynamic environment and captured well the observed feature of sea breeze. When comparison with simulations of the standard MM5, it was found that the uMM5 better reproduced urban impacts on temperature (especially at nighttime) and urban wind flows: roughness-induced deceleration and UHI (Urban Heat Island)-induced convergence.

The impervious area on the surface of urban area has been increased as buildings and artificial land cover have continually been increased. Urban development has gradually decreased the green zone in downtown and alienated the city from the natural environment on outskirt area devastating the natural ecosystem. There arise the environmental problems to urban area including urban heat island phenomenon, urban flood, air pollution and urban desertification. As one of urban plans to solve such problems, green roof system is attracting attentions. The purpose of this study was to investigate flood discharge and heat reduction effect according to the green roof system and to quantify effect by analyzing through simulation water and heat cycle before and after green roof system. For the analysis, Distributed hydrologic model, WEP (Water and Energy transfer Processes) and WEP+ model were used. WEP was developed by Dr. Jia, the Public Works Research Institute in Japan (Jia et al., 2005), which can simulate water and heat cycle of an urban area with complex land uses including calculation of spatial and temporal distributions of water and heat cycle components. The WEP+ is a visualization and analysis system for the WEP model developed by Korea Institute of Construction Technology (KICT).

2001년 인천국제공항의 개장과 함께 과거 우리나라 항공 수출입 관문 역할을 담당하던 김포공항의 항공물류 거점 기능은 급격히 쇠퇴하였다. 그러나 김포공항 지역의 입지적 이점에 힘입어 김포공항 물류단지는 오늘날 수도권의 중요한 도시물류 거점시설로 기능하고 있다. 분석결과 인천공항의 배후물류단지, 수입화물 중심의 부가가치 물류활동 그리고 수도권 지역의 도시물류 배송센터 역할 등은 현재 김포공항 물류단지에서 수행되는 대표적인 기능으로 파악된다. 하지만 도시물류 거점시설로서 공항물류단지의 기능은 향후 운영주체(공항공사)의 수익성 제고 전략에 따라 축소될 우려가 있다. 김포공항 물류단지가 공공 기능을 수행하는 도시물류 거점시설로 지속적으로 발전하기 위해서는 국가 및 지역 단위 물류거점(시설) 개발전략과 체계적으로 연계되어야 하며, 이를 위해서는 관련 법령 및 기본계획의 종합적인 정비가 수반되어야 할 것이다.

This study does try to proceed on the assumption that complex buildings can vitalize urban life of contemporary society from contemporary complexity and cases of past failure. The scope of investigation on complex buildings in Sangju built in 1990s' and 2000s' on this thesis is that site size is 400 square meter, total area 1500 square meter, and the number of stories on the ground below 5 floor. Method of investigation on twenty one buildings which have been built on new C.B.D. between the Namwon avenue and the Joongang 1th street in Sangju is through field investigation, field photographs, recordings and drawings on these buildings. Investigative contents have been divided and analysized into physical and functional elements in urban and architectural dimension. On the basis of these results, the future planning approach of complex buildings in medium and small cities has been considered into planning principles of convenience of building use and efficiency of site size, physical plans reflected on the traffic and pedestrian movings and the face of buildings, pedestrian resting space-creation like plazas and central gardens, regional character reflected with urban context, and separation and union of approached movings interrelated among the components.

To adjust the discrepancy between Light Detection and Ranging (LIDAR) strips, previous researches generally have been conducted using conjugate features, which are called feature-based approaches. However, irrespective of the type of features used, the adjustment process relies upon the existence of suitable conjugate features within the overlapping area and the ability of employed methods to detect and extract the features. These limitations make the process complex and sometimes limit the applicability of developed methodologies because of a lack of suitable features in overlapping areas. To address these drawbacks, this paper presents a methodology using area-based algorithms. This approach is based on the scheme that discrepancies make complex the local height variations of LIDAR data whithin overlapping area. This scheme can be helpful to determine an appropriate transformation for adjustment in the way that minimizes the geographical complexity. During the process, the contour tree (CT) was used to represent the geological characteristics of LIDAR points in overlapping area and the Iterative Closest Points (ICP) algorithm was applied to automatically determine parameters of transformation. After transformation, discrepancies were measured again and the results were evaluated statistically. This research provides a robust methodology without restrictions involved in methods that employ conjugate features. Our method also makes the overall adjustment process generally applicable and automated.

The purpose of this study is to present an appropriate approach to urban regeneration by analyzing Gwangju Metropolitan City. For the study, residential area of Asia Culture Complex was analyzed based on GIS. The areas concerned were categorized and looked into by their Situation based on the analysis of urban infrastructure state. However, as the architectural space within a city are limited, and accurate assessment of them is needed. The residential areas have the following characteristics. They become an aging and dilapidating residential and socially underprivileged-concentrated area. It is necessary to set up a direction for a future-oriented planning for the development of these areas. Along with a decreasing population, it is important to improve the urban architecture environment for the elderly in an aging society. The economic growth of a city if necessary for the future. Therefore, the criteria for the assessment is required. And the subsequent setting-up and planning of a future direction for a city is badly needed. After that, an accurate assessment of a city called for. City space allows for various interpretations. As the rich are getting richer and the poor are getting poorer, a wealth is concentrated on one district or an area.

e o최근에 들어 도시지역에서는 국지성 집중호우에 의한 홍수피해가 증가하고 있다. 심지어 우수설비 시스템이 비교적 잘 갖추어진 개발 지역에서도 기존의 우수설비시스템의 용량이 초과되어 큰 침수피해가 발생하고 있다. 이로 인해 건물， 공공기반시설 등 재산 및 인명 등에 있어 많은 피해를 야기하고 있으며, 도로의 침수는 운송 시스템의 기능에 문제를 일으키게 되어 도시의 산업과 기능을 마비시킨다. 이러한 도시지역 홍수에 대비하여 도시지역의 복잡한 지형 형상과 인위적 배수시스템을 함께 고려하여 해석할 수 있는 적절한 침수해석모형이 필요하다. 본 연구에서는 배수시스템 해석 모형인 SWMM모형과 도시침수해석 모형인 DEM 기반 침수해석모형을 통합하고, 두 모형간의 유량의 전송과정을 수리학적 관계를 고려한 이중 배수(Dual-Drainage) 개념에 의한 도시침수해석모형을 이용하였다. 본 연구에서는 이중배수 침수해석모형을 수정하여 건물의 영향을 고려할 수 있도록 구성하였다. 본 모형의 개발로 침수상황의 시간별 진행과정을 분석함으로써 도시홍수에 대한 침수위험지점 파악 및 홍수 취약지점에서의 긴급대피 계획수립 등에 활용될 수 있을 것으로 판단된다.
