본 연구에서는 도시의 급격한 발달로 인해 왜곡된 물순환을 나타내고 있는 도림천 유역에 대해서 물순환 회복을 위한 대안 중 침투증진시설의 효과에 대한 모의를 수행하였다. 물순환 모의는 도시유역의 물순환 정량화를 목적으로 개발된 WEP(Water and Energy transfer Processes) 모형을 이용하였으며, 침투증진시설로는 침투트랜치와 투수성 포장재의 설치효과를 분석하였다. 물순환 회복효과는 도시개발 이전의 유출특성과의 비교를 통해 평가하였으며, 이를 위해 1975년의 토지이용도로 도시개발 이전의 물순환 모의를 수행하였다. 모의결과 도시화에 의해 불투수율이 과거보다 $18.7\%$ 증가한 것을 알 수 있었으며, 이로 인해 첨두시간은 감소하고, 첨두 및 총유출량은 증가한 것으로 나타났으며, 침투량과 기저유출량이 감소한 것을 확인할 수 있었다. 침투증진시설의 설치효과는 침투트랜치와 투수성 포장재의 개별적인 설치보다는 두 가지를 함께 적용했을 경우에 도시개발 이전의 유출특성에 근접하는 것을 알 수 있었다.

현대의 도시재생사업은 도시의 기존 모습을 유지하면서도 낙후된 도심 환경을 개선하여 원주민의 재정착률을 높이고 쇠퇴한 구도심에 새로운 활력을 불어넣는 것을 목표로 한다. 도시재생에서 환경조형물은 이러한 시대적 요구와 그것이 놓이는 장소 혹은 공간이 가지는 의미, 공공성 또는 공익성이라는 영역에서 예술적 가치를 창출해야 한다. 이 논문에서는 마을흔적보전사업의 환경조형물을 '리사이클, 업사이클, 뉴사이클'이라는 3개 유형으로 나누어 살펴본다. 이를 통해 환경조형물이 예술적 가치뿐만 아니라 마을흔적보전이라는 사회적 역사적 문화적 가치를 담아냄으로서 도시재생이 가지고 있는 목표를 실현하는 중요한 요소가 될 수 있음을 알 수 있다.

This study investigates correlations between the impacts of urban and building form and microclimate on the energy consumption of buildings. It applies microscopic elements such as urban form, building form and character, and microclimate as factors in the energy consumption of buildings. To this end, the energy consumption of selected buildings in Seoul in August of 2017 was analyzed. Based on microscopic elements within a radius of 500 meters of 23 Automated Weather Station (AWS) measurement points selected by the Meteorological Office of the City of Seoul. With the exception of a few elements, the urban form and character elements demonstrate a significant relation to the energy consumption of buildings. It is also found that microclimate elements such as wind speed and humidity are pertinent to the energy consumption of buildings. It is helpful in that it suggests results for establishing more effective policies and strategies for enhancing the sustainability and resilience of cities.

This thesis concerns urban construction archive management business of China in the 20th century 12 items of state level construction archives, 11 categories of urban construction archives was initially studied. And studies on data collection method, obligations and range of service, etc. of urban construction archives center were conducted as well. Urban construction archive management business was aggressively pursued in terms of national policy, based on the state plan to construct medium-sized and large cities and Mao ZeDong(毛澤東)‘s direction regarding of urban construction archives. As a result, there happened to be various levels and types of 3,186 archive centers, as of 2003. And the archives centers of urban construction have been estavlished in 662 cities all over China so far, while the establishment of the urban construction archives centers was pursued only in 42 cities in 1960s. Another point to note is that staff members of junior college or higher educational background account for 70% - 80% of overall human resources of the archives center of urban construction, while 60 - 70% of them are technical level. This makes professional human resources represent at least 60% of the total human resources of the centers. This is a result of effort of China to enhance urban construction archive management business on both quantitative and qualitative level. And through the study on the situation of urban construction archive management business in Beijing(北京), it was learned that urban construction archives are being collected and managed in archives centers of the respective areas as well as in professional archives centers of urban construction. Some suggestions were also made regarding what kind of direction Korea should take to pursue the business of urban construction archive management.

Due to climate change, population growth, and economic development, the demand for water in the urban water system (UWS) and the energy required for water use constantly increase. Therefore, beyond the traditional method of considering only the water sector, the Nexus approach, which considers synergies and trade-offs between the water and energy sectors, has begun to draw attention. In previous researches, the Nexus methodology was used to demonstrate that the UWS is an energy-intensive system, analyze the water-energy efficiency relationship surrogated by energy intensity, and identify climate (long-term climate change, drought, type), geographic characteristics (topography, flat ratio, location), system characteristics (total supply water amount, population density, pipeline length), and operational management level (water network pressure, leakage rate, water saving) effects on the UWS. Through this, it was possible to suggest the direction of policies and institutions to UWS managers. However, there was a limit to establishing and implementing specific action plans. This study built the energy intensity matrix of the UWS, quantified the impact of city conditions, external influences, and operational management levels on the UWS using the water-energy Nexus model, and introduced water-energy efficiency criteria. With this, UWS managers will be able to derive strategies and action plans for efficient operation management of the UWS and evaluate suitability and validity after implementation.

본 연구에서는 도시홍수 피해 저감 및 회복을 위한 도시홍수 연관 데이터 가시화 및 GIS 기반 LoD 1 수준 가시화 기술 개발을 진행하였다. 도시홍수는 불투수지역의 증가로 인한 첨두 홍수의 증가 및 도달 시간의 단축, 도시 내수배제의 불량으로 인한 주택지 및 상가 공장지 등의 침수에 의한 피해가 발생하는 현상이며, 도시홍수 예측 모델을 수행하기 위하여 수집한 기상, 하천 및 수자원, 토양 등의 데이터를 2차원 가시화하고 도심 지역의 지형 DEM(Digital Elevation Model) 데이터 및 건축물 DSM(Digital Surface Model) 데이터를 기반으로 3D 가시화를 진행하였다. 기상, 하천 및 수자원 관측 등의 데이터를 실시간으로 수집하며 관련 데이터를 도시홍수 디지털 트윈 플랫폼의 수문기상정보를 통하여 가시화 제공하며 토양 및 지리정보는 WMS 레이어를 기반으로 2D 가시화한다. 건축물 데이터의 경우 GIS 정보를 기반으로 하는 3D 객체 배치를 위하여 WGS84 타원체를 활용하여 EPSG:4326 좌표계를 적용하여 가시화하였다. 건축물 가시화는 PostgreSQL로 구축된 데이터를 Geoserver를 활용하여 자동으로 층 정보를 통한 건축물의 높이를 계산하도록 하였으며, CesiumJS를 적용하여 웹 기반 도시홍수 디지털 트윈 플랫폼을 개발하였고 추후 LoD 3 수준으로의 확대 적용 기반을 마련하였다.

The purpose of this paper is to grasp levels of cost burden in pollution treatment by measuring efficiencies and shadow prices by pollutants in Korean cities. The efficiencies and shadow prices of pollutants will be compared for cities divided by Seoul metropolitan area and non-Seoul metropolitan area. Annual shadow prices of NOx, SOx, and PM10 emissions in the cities of Seoul metropolitan area are 0.846, 0.318, 0.816, respectively for 1999-2005. The annual shadow prices in the cities of Non-Seoul metropolitan area are 0.848, 0.272, and 0.789, respectively over the same periods. The shadow prices of SOx showed similar levels between two areas but those of NOx and PM10 of cities in Seoul metropolitan area were higher. NOx emission quantities of both areas have similar increasing patterns because the NOx has mainly increased with augmentation of transportation regardless of Seoul metropolitan and non-Seoul metropolitan areas. It seems that the reason the shadow prices of two pollutants for the cities of Seoul metropolitan area are higher, is because environmental regulation is stronger in the cities of Seoul metropolitan area, the cities of Seoul metropolitan relatively show higher quantities of pollution reduction under given desirable outputs, and generally have industrial sectors with small pollution emission. In the future we need to reduce pollutants in the various respects such as adjustment of overall industry structure, energy consumption pattern, and reviews of arrangement of living space for the cities located on the downward-sloping segment of production frontier.

This study investigates how much building area among total building area concentrates on urban region in a local government region and then, I applies 'The Index of Building Concentration in Urban Area' for the first time in a study. The finding shows that Cities' Index is higher than counties', and also shows that a lower index is associated with a higher rate of older adult population, and is also associated with higher general budget expenditure by the local government based on the index of Building Concentration in Urban Area in Gyeongbuk Province. This study provides evidence that the Index of Building Concentration in Urban Area can be utilized in measuring shrinkage level, effectiveness of municipal finance, and in establishing shrinkage city/county planning by basic data.
