In international communities such as UN-Habitat, Asian Development Bank, OECD, and etc. the importance of formulating and planning for equal living of all citizens within a city regardless of any social hierarchy is being recognized recently. For this purpose the concept of 'the inclusive city' is introduced, which requires the collective consideration of physical and social factors in urban planning. This study aims at the establishment of efficient indicators in order to graft the concept of the inclusive city on urban design, and at searching a plan capable of improving the inclusiveness through applying the developed indicators to an urban space actually. After introducing the indicators the priority orders of those are searched through AHP analysis and the corelation with the factors of urban planning is examined and analysed based on the priority, so as to suggest an efficient and practical plan for promoting the inclusive city in future.

최근 세계적인 기후변화로 인한 홍수의 빈도 및 규모가 커지게 되면서 최초 구조물의 설계시의 설계용량을 초과하는 국지적 집중호우가 발생하고 있다. 이는 도시방재를 위하여 기계획하였던 내수배제 시스템의 설계성능을 넘어 도시지역에 침수를 유발하게 된다. 이에 대한 해결책으로 도시의 내수배제 시스템을 개선하기 위한 우수저류조, 우수관거개선 등이 이루어지고 있지만 설치 이후 구체적인 효과분석이 이루어지지 않고 있다. 본 연구에서는 우수저류시설의 설치 여부에 따른 침수발생 양상을 분석하고 우수저류시설 침수저감효과를 정량적으로 분석할 수 있는 방안을 제시하였다. 이를 위하여 XP-SWMM을 이용하여 2차원 침수해석 모의를 실시하였고 다양한 조건에서의 모의를 위하여 2차원 침수해석 모의조건을 설정하였다. 기계획된 우수저류시설의 설계시의 임계지속기간을 기준으로 IDF Curve를 통하여 설계강우량, 확률강우량 및 방재성능목표량을 재산정하였고 Huff4분위법을 이용하여 강우분포를 시켜 XP-SWMM에 적용하였다. 또한, 유역 최종 방류구에서 기점수위 조건과 자유방류 조건을 분리하여 모의하였으며 최종적으로 우수저류시설의 설치여부에 따른 2차원 침수해석을 실시하였다. 2차원 침수모의 결과를 이용하여 월류량의 저감율과 격자별 침수심 분포 분석을 진행하였다. 월류량은 총량적인 지표를 가지고 있지만 격자별 침수심 분포 분석은 격자의 최대 침수심을 0.1m 간격으로 나누어 각 단계별 침수심 격자의 발생빈도를 산정하였다. 제안된 방법을 사용하여 분석을 진행한결과 우수저류조를 설치한 후에 격자의 최대침수심이 더 낮은 침수심 단계로 이동한 현상을 확인하였다. 이는 구조물의 설치 후에도 침수가 일어난다는 양적인 면이 아닌 격자의 침수심 분포 양상을 통해 도시침수에 직접적으로 저감이 나타나 효과를 기여할 수 있다는 지표라고 판단된다.

Although competitions for large parks are increasing rapidly across the world, theoretical research and critiques of these competitions are as yet insufficient. The 'International Design Competition for Central Open Space in Multi-functional Administrative City, Korea', a representative competition for large park design, can be a significant resource for examining the contemporary design strategies that go into the design of a large park. In this study, the authors make a framework for analysis by looking at the competition's design guidelines and literatures on 'large parks', and by then analyzing the ten finalists. Four questions that were derived from the framework were: 'what are the approaches to large parks?', 'what is the process of design?', 'what is the sustainability of the park?', and 'what are the relations between city and park?' The results of the study are as follows. First, the design concepts for large parks are primarily site-specific. It is particularly important in ensuring the identity of the large park. Second, it is difficult to find design proposals which satisfy the four main questions sufficiently, and works submitted tend to be visual-oriented, form-oriented, and results-centered. Third, the notion of 'sustainability' in large parks is a comprehensive one which includes various aspects such as ecology, finance, programming, and community. However, the notion remains ambiguous, and plans for operation and management are not concretely proposed. Finally, design proposals for large parks accompany positive relations with the city. Especially, 'productive parks' and 'city self-sufficiency' are very important demands in regards to large parks.

This study proposes urban development concept and strategies for Garden City, focused on Solaseado, Yeongam Heanam Tourism-Leisure Type Enterprise City in Korea. Understanding that an essential element of a garden is the endless care performed by gardeners, the Garden City development concept suggests applying this idea to making planned cities by cultivating the potential natural landscape of the site in the long run. The meaning of Garden City can be defined in three aspects; an attitude and process of planning a city, a system for constructing the spatial structure of a city, and city branding. A Garden City is a city structured with the spirit of a garden, a city where open space networks become the urban structure, and a city that builds its identity through the landscape, respectively. From this point of view, the research draws development strategies with spatial design examples to embody the Garden City concept in Solaseado by following three steps; establishing the main urban axes, creating city networks through the conjunction of the axes, and categorizing and systematizing open spaces within the city. Consequently, the study shows an alternative urban planning model that extends the concept of a Garden City while maintaining the intrinsic landscape as an urban resource. In addition, the conceptual master plan of Solaseado will structure the urban landscape and park system according to the Garden City strategies.

Cities face new challenges not only in natural disasters by climate change but also in social and economic fluctuations. With the existing simple reconstruction method, it is difficult to solve the overall problems that a city or region may face. As a new approach to cope with various changes, the concept of resilience is emerging. Resilience is also one of the themes of recent major urban design projects. Design with the concept of resilience is a new strategy that can deal with various changes of urban space, rather than a temporary trend. The purpose of this paper is to explore the design method by analyzing cases where the concept of resilience is employed. We aim to examine what kind of design strategies are needed for the resilience design and how this design process differ in character, as compared to general design projects. Cases for this study include the "Rebuild by Design" competition held in 2013 and the "Resilient by Design/Bay Area Challenge" competition held in 2017. This paper consists of literature reviews and case studies. The latter is divided into two aspects: content analysis based on the theory of resilience and characteristics of the design process. Cases are analyzed through literature reviews and process characteristics of resilience design in response to the general design process. The main categories for urban resilience used as the framework for analysis include: Urban Infrastructure, Social Dynamics, Economic Dynamics, Health and Wellbeing, Governance Networks, and Planning and Institutions. As a result, the aspects of resilience concepts considered and design strategies undertaken by each team were identified. Each team tried to connect all 6 categories to their design strategies, placing special value on the role of governance, a system that enables collaborative design and project persistency. In terms of the design process, the following characteristics were found: planning the whole project process in the pre-project phase, analyzing predictable socioeconomic risk factors in addition to physical vulnerabilities, aiming for landscape-oriented integrated design, and sustainable implementation strategies with specific operations and budget plans. This paper is meaningful to connect the concept of resilience, which has been discussed in various articles, to design strategy, and to explore the possibility of constructing a practical methodology by deriving the characteristics of the resilience design process. It remains a future task to research design strategies that apply the concept of resilience to various types of urban spaces, in addition to areas that are vulnerable to disasters.

In order to implement smart cities that will become living spaces in the fourth industrial revolution era, detailed privacy information such as residents' living information, buildings and facilities information must be collected and processed in real time. While city functions and convenience for individuals are being facilitated, threats to personal information exposure and leakage are also likely to increase at the same time. Therefore, the design concept for personal information protection should be considered and accordingly reflected from the stages of smart city design, technology development and operation planning of intelligent information (AI) facilities. The results of the analysis show that for activation of smart cities and operation of data-driven cities, the concept of Privacy by Design (PbD) has already been introduced in the institutional, industrial and technological aspects, particularly in the cases of European countries and the US. In order to strengthen the local and global competitiveness of smart cities and the country, Korea also needs to actively deploy PbD as a strategy to secure a data-driven economy, which is the core strategy for smart cities. Therefore, the study suggests policy implications focused on approaches to legislative improvement and technology development support, which reflect the basic properties of PbD as defined in the study.

현재 우리나라는 1970년대 이후 급속한 경제성장으로 인하여 산업화 및 도시화 현상이 심화되고 있는 실정이며, 이러한 과정에서 불투수층의 증가로 인하여 첨두유출량의 증가, 자연유역에서 도시유역으로 변하면서 유역내 도달시간의 감소 등의 수문학적 특성이 변화로 예기치 못한 홍수로 인하여 피해가 발생하고 있다. 다라서 첨두유출량이 관망으로 전달되는 과정에서 관에 발생하는 부하의 증가로 인하여 내수침수 피해를 입게 되는데, 도시 유역에서의 인구 증가 및 산업활동에 따른 도시 개발로 인한 불투수면적의 증가로 우수유출량이 커지고 있으며, 저지대의 활용이 증대됨에 따라 내수 피해는 더욱 증가되고 있는 실정이다. 이러한 도시 유역의 재배 저감 대책 수립을 위해서는 먼저 실측자료와 도시유출 모형에서 산정된 첨두유출량과의 비교$\cdot$분석하여 최적의 모형을 채택하여야 한다. 또한 채택된 모형으로 적절한 설계 강우량이 선정되어야 하고, 그에 따른 유출량을 정확히 산정하여야 하나, 설계 강우량 산정을 위한 강우의 지속시간의 결정에 대해서 일반적인 기준이 확립되지 못하고 있는 실정이기에 재해 저감 대책 수립에 많은 어려움이 따르고 있다. 이에 본 연구에서는 실측 강우량, 첨두유출량 및 유출총량과 도시지역의 유출량 산정에 사용되어지는 ILLUDAS, SWMM 모형에 모의치와의 비교 연구를 통해 최적의 도시유출모형을 제시하고자 한다. 따라서 실측자료가 있는 서울시 장안$\cdot$뚝섬배수구역의 실측 강우와 펌프장에서 조사된 실측 유량과 ILLUD AS, SWMM 모형에 의해 산정된 유량과의 비교 분석 결과 SWMM 모형에 의한 첨두유량이 실측 첨두유출량과의 오차율에서 장안배수구역은 $21.1\%$, 뚝섬배수구역은 $4.3\%$로 가장 근접한 결과를 나타내었으며, 총 유출량에서도 각각 $7.8\%,\;13.2\%$의 오차율을 가지는 것으로 분석되어 타 모형에 비해 실유량과의 차가 가장 적은 것으로 모의되었다. 향후 도시유출을 모의하는 데 가장 근사한 유출량을 산정할 수 있는 근거가 될 것이며, 도시재해 저감대책을 수립하는데 기여할 수 있을 것이라 판단된다.
