Among various Green Infrastructure measures for urban stormwater management, effects of porous pavement were quantitatively examined in terms of hydrological cycle. Different scenarios for porous pavement were introduced on a SWMM model and the effects were compared and analysed using discharge hydrographs. Two types of pavements having different runoff coefficients (0.05 & 0.5) were introduced to cover different ratio of entire road areas (100 %, 77.5 % and 40.4 %) and these made up in total 6 different scenarios. Total runoff volume was reduced and peak flow was significantly decreased by applying the porous pavement. The highest reduction for total runoff was shown from S-6(covering area: 100 %, runoff coefficient: 0.05) as 19 % followed by S-5(covering area: 77.5 %, runoff coefficient: 0.05, 16 %), while that of S-2(covering area: 40.4 %, runoff coefficient: 0.05) and S-1(covering area: 40.4 %, runoff coefficient: 0.5) were the lowest with 8 % and 5 %. This proved that the application of porous pavement would improve urban hydrological cycle.

The function failure of present major facilities is likely to lead to failure of related systems and/or whole facilities, increasing the necessity for protection of infrastructures, main structures, and major industrial facilities. In addition, safe and efficient management for urban infrastructure (waterworks and sewerage facilities, electricity, telecommunications, roads, etc) installed in the basement or on large cities grounds at various public areas is required. Recently in response to this demand, efforts for vitalizing asset management are being made such as enacting related laws and developing asset management system in the U.S., Australia, Europe and other advanced countries with the concept for a new maintenance. In our county, identifying maintenance system problems such as aging and rapid increasing of existing infrastructures and decision-making about updating maintenance is required for systematic and organizational maintenance. In this study, by comparing and observing the LOS(Level of Service) of each countries' waterworks and risk-based LOS, we suggest the direction of future urban water infrastructure management systems for more effective management.

This paper discusses several topics associated with the densification caused by supertall buildings and their impact on city systems. The paper covers five key areas where a supertall tower creates a concentration of needs and effects. First, the paper comments on population shifts towards the city and how they affect carbon footprint, utilities infrastructure and transport. The effect of single- and mixed-use towers is discussed in the context of population density. The second section brings the issues of transit, accessibility and master planning into focus. The use and criticality of public transport, cycling and walking is described. Servicing and deliveries using freight consolidation and shared systems is also discussed along with their contribution to the culture of sustainable travel. In the third section the paper reflects on supertall buildings' below-ground utilities and drainage provision, particularly the challenges faced in established city infrastructures. The utilities issues associated with supertall concentration (in land-use terms) compared to equivalent low-rise distribution is also commented on in the context of surface water runoff. In the fourth section, the topic of supertall sustainability is discussed and how city systems need to respond to create desirable and affordable space for occupiers. The changing need for vertical communities, 'stacked neighbourhoods' and the notion of a micro-city is described. Finally, the paper considers the energy consumption and resilience of supertall buildings in the context of basic geometry, façade design, climate and mixed-use benefits as they impact city systems.

Rural decline due to the decrease of the local population is an inevitable phenomenon, and a vicious cycle has been formed between a lack of basic living services and a population decrease in rural areas. Therefore, the study aims to derive the migration decision-making characteristics based on basic living service infrastructure data in rural areas. To do this, the population change over the past 20 years was categorized into six types, and the relationship between the classified population change types and the number of basic living service infrastructures was analyzed using decision tree analysis. Of the total 3,501 regions, 801 regions were the continuous decline type, of which 740 were rural areas. On the other hand, among 569 regions that were the continuous increase type, 401 regions were urban areas, confirming the population imbalance between rural and urban areas. As a result of the decision tree analysis on the relationship between population change types and the distribution of basic living service infrastructure, the number of daycare centers was derived as an important variable to classify the continuous increase type. Hospitals, parks, and public transportation were also found to be major basic living services affecting the classification of population change types.

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.

Elevated linear parks have the potential to support the ecological stability, city amenity, cultural opportunity, and health benefits of urban dwellers; these are increasingly becoming an integral part of the urban infrastructure. Due to structural limitations in space, linear parks need to be planned to increase the value of green space. This study was aimed at advancing urban planning techniques for increasing the value of elevated linear parks, by comparing the Seoullo7017 with the Promenade $plant{\acute{e}}e$ and the Highline. Planning characteristics of these green spaces were analyzed from the perspectives of physical planning factors, amenity values for users, and management systems. Field surveys and virtual tools were used to investigate the current characteristics of these parks, in addition to the literature survey. From the analysis of planning factors, amenity values, and management in the three linear parks, following important recommendations were made in order to promote the values of these parks: (a) diversify planting design for increasing the diversity of green space in a narrow area; (b) bring in various forms of amenities to promote the quality of users' experience; and (c) establish community-based management systems for enhancing regional competitiveness and profit sharing in urban regeneration projects.

과거 성장 중심의 산업화 과정에서 형성된 대규모 산업단지를 비롯한 공업지역이 기반시설 부족과 노후화로 인해 지방도시의 도시경쟁력을 악화시키는 요인으로 작용하고 있다. 이러한 인식하에 최근들어 정부주도의 노후산업단지 재생사업이 시범적으로 추진되고 있으나 지역마다의 산업단지의 형성여건과 물리적 환경이 상이하여 획일화된 재생계획의 우려가 있는 실정이다. 이에 본 연구에서는 과거 민간주도로 조성된 부산 사상공업지역을 사례로 지역의 사회적 여건과 물리적 현황을 바탕으로 지역특성을 진단하고 재생방향을 제시하고자 하였다. 분석결과 사례지역은 사회적 측면에서 시역확장에 따른 입지적 도시기능 변화와 김해, 양산 등 주변도시의 급격한 성장에 따른 기업유출로 공업기능의 잠식, 물리적 여건측면에서는 기반시설 미흡 및 개발압력 가중으로 요약된다. 이를 바탕으로 향후 수립할 재생정책의 방향으로서 계획수립단계에서는 공공주도의 기반시설 확충에 우선하고 시범적으로 일부지역에 대한 우선정비구역 지정을 통한 전면철거방식 적용이 필요하다. 실행단계에서는 중장기적 관점에서 단계적 사업이 필요하며 협력적 거버넌스 구축을 통한 재생사업 추진과정에서 기업과의 공감대 형성이 중요할 것으로 여겨진다.
