As the spatial structure of a region is evolving into a decentralized multi-nucli model, networked connection among cities in a region is emerging as an important issue to strengthen regional competitiveness. This paper focused on the limitation of current new town planning criteria which just suggest a uniform standard for economic self-sufficiency by new-town size, without representing the network characteristics of new town. If a new town is planned as a economic strongpoint within a region, it needs to secure appropriate industrial functions. This study classified the characteristics of new towns by network analysis and reviewed the economic self-sufficiency criteria by new town types. Using various network connectedness indices, the 1st and 2nd round new towns in the capital region were analyzed, and land-use distribution of new-towns in other countries were also examined comparatively. The network characteristics of new towns are classified as three types: mono-nucleus, distributed center, and dependent. Based on this classification, planning criteria for self-sufficiency were compared among 6 new towns. This study provides implications for the amendment of "the sustainable new town planning criteria" or the revision of development plans.

The purpose of this study is to conduct an analysis for classification of unexecuted urban planning facilities using the Geographic Information System(GIS) to prepare measures for systematic and efficient management of unexecuted urban planning facilities and to find ways to establish national territory information for continuous management and operation by database of spatial data of classified unexecuted urban planning facilities. For this purpose, the present state of urban management plan, thematic map, cadastral map, satellite image of Korea Land Information System(KLIS) were collected from Miryang City, and qualitative analysis of the execution and non-execution of urban planning facilities was conducted by combining the layer of urban planning facilities, satellite images, and continuous cadastral layers of cadastral maps with classified and processed owner attribute information. According to the analysis, the unexecuted facilities were derived as unexecuted facilities, as most of the private land, without any current status roads or facilities created in satellite imagery. In addition, although the current status road was opened, the facilities that included some private land were derived as facilities that were recognized and executed by the local government as the de facto controlling entity through public transportation. The derived unexecuted urban planning facilities were divided into layers of shape data and the unexecuted property data were organized to quickly and accurately identify the status of non-executed and statistical information. In this study, we proposed an analysis plan that introduced GIS technology for scientific and rational analysis of unexecuted urban planning facilities and the establishment of reliable spatial data, and proposed a plan to establish a database for connection with existing systems and use of information.

The purpose of this study is to diagnose urban spatial structures using spatial modeling techniques for balanced urban development as part of sustainable urban growth management. Since urban spatial structure is an interaction of various activities, it is necessary to interpret the analysis results in conjunction with the analysis of changes in spatial structural elements. In this study, population and transportation were approached for research purposes. Population data were applied to the Getis-Ord G_i^* method, a spatial statistical technique, to analyze the concentration-decreasing region of the population. Traffic data analyzed the trend of centrality change by applying commuting traffic O-D data to Social Network Analysis techniques. The analysis showed that urban imbalance was growing, and the centrality of transportation was changing. The results of the analysis of spatial structure elements could be interpreted by linking the results of each factor to each neighborhood unit, predicting changes in urban spatial structure and suggesting directions for sustainable urban growth management.These results could also be used as a decision-making tool for various urban growth management policies introduced to cope with rapid urban development and uncontrollable development in many cities around the world.

기후변화에 따른 빈번한 태풍과 집중호우로 인해 지속적으로 피해규모가 증가하고 있으며 점차 다양한 지역에서 피해가 나타나고 있다. 과거 태풍 루사나 매미의 경우 도시유역에서 주요 피해가 발생하여 대규모 피해를 야기하였으나 2006년 발생한 태풍 에위니아의 경우 집중호우로 인한 배수문제, 산사태로 인한 토석류 발생과 이에 따른 도로 및 하천 유입으로 피해가 나타났다. 이러한 피해는 남해안 및 영남지방, 강원 영서지방에서 주로 발생한 것으로 과거 피해 유형과 차이가 난다. 기존 하천 중심의 치수대책만으로는 다양한 지역특성을 고려한 치수계획을 종합적으로 수립할 수 있는 한계가 발생하며 이에 따라 국토해양부(2001)는 수자원 장기종합계획에서 하도와 유역 시스템을 함께 고려하는 유역종합치수정책을 제안하였다. 홍수피해잠재능은 수자원장기종합계획(2001)에서 처음 제시된 개념으로 면 개념을 도입하여 공간적 비교가 가능하고, 단위구역의 치수특성 및 사회경제적 가치를 평가할 수 있도록 개발된 지수(이승종, 2006)이며, 치수안전도 설정을 위한 가장 중요한 개념으로 활용되고 있다. 그러나 최근에 제시된 개념으로 아직 이론적 기반이 미흡하며 지속적인 연구를 통해 수정된 개념이 제시되고 있는 실정이다. 본 연구에서는 유역종합치수계획 등 국가 치수정책을 수립하기 위해 중요한 개념인 홍수피해잠재능과 치수안전도의 치수계획 활용 사례를 조사하여 지역특성별로 유역분할기법을 조사 정리하였으며 국외 사례를 분석하여 유역분할기법의 발전 방향을 제시함으로써 유역단위 맞춤형 치수계획 수립을 위한 기초 자료를 제공하고자 한다.

Recently, the location of urban parks has become more important in terms of the construction of an environment-friendly, sustainable city. To build a refined and desirable urban park, it is necessary to have precise understanding on the evaluation of supply adequacy and selection method for its location. However, there have been few studies on the spatial imbalance and location plan of urban parks. Therefore, this study has attempted to evaluate the spatial imbalance of urban parks in Hwanggeum-dong, Suseong-gu in Daegu and propose a policy suggestion to solve the imbalance. According to the analysis, Hwanggeum 1-dong and 2-dong recorded 943.08$m^2$/GRID and 380.61$m^2$/GRID, respectively, in terms of legal requirements for urban parks and 406,730.80$m^2$ and 157,086.40$m^2$ in terms of total service supply from two neighborhood parks and four children's parks. According to the evaluation of optimal supply area across Hwanggeum-dong, Hwanggeum 1-dong and 2-dong recorded 12.3% and 51.5%, respectively. In an evaluation of the supply adequacy of urban parks, the areas described as 'very satisfying' were 20.5% and 5.4% in Hwanggeum 1-dong and 2-dong, respectively. On the contrary, the areas described as 'very dissatisfying' accounted for 27.6% and 10.8%, respectively, in the two regions. It appears that additional parks should be developed in the inferior areas in terms of urban parks in consideration of various factors such as area and shape. The results of the supply adequacy evaluation will be used as a tool to figure out and solve problems in the location of urban parks and as basic data for a master plan to build an environment-friendly, sustainable city.

Recently, housing prices in metropolitan areas is also increasing in the UK and Australia. Their governments are trying to solve this problem by the housing development in the quarry sites near cities. The cases reviewed in this study, Erith Hill Quarry (The Quarry), Plymstock Quarry, Lilydale Quarry (Kinley), and Bombo Quarry are the mixed-used development cases in the closed quarry sites through the urban planning system. In the UK, the local government uses the urban planning scheme such as the planning permit system, section 106. The local government permits the quarry site development on the condition that it provides necessary public facilities, such as schools and affordable housing for the local community. In Australia, local governments use up-zoning permission rights to convert land uses in quarries from industrial to mixed-use. Development plans have to include urban infrastructure and open space in addition to affordable housings. In the case of Australia, establishing a development plan in advance and filling the quarry pit with overburden through a phased development is expected to have the effect of reducing the project cost. Both countries think that developing brownfields, such as quarry sites, is a more sustainable and eco-friendly development from the perspective of future generations than developing new green fields. Such a perspective of the UK and Australia will be able to give policy implications for our slightly rigid urban development system.

A drastic development of modern cities and transportation means as part of a rapid industrialization and urbanization for the past half-century has consistently broaden the boundaries of urban dwellers while, at the same time, raising issues as to establishing relationships among them throughout the society following the materialization of modern urban planning. Within the framework of the postmodern concept, there have been consistent efforts to create a community space in appropriate size and, in particular, the concept of New Urbanism and Urban Village that emerged in mid 1800s along with the effort to build a community by building an ideal city provides an important meaning today when people are seeking to restore a healthy community. Against this backdrop, this study aims to explore the concept of community and to determine its optimal scope of implementation in the sense of healing environment under the premise that organizing a healthy city is based on building a solid urban community. The study findings and conclusions are as follows. First, a community is a subject of constant consideration in the process of historical development of the city and has required us to take a variety of strategic approaches and to determine the scope of implementation. Second, the activities of a healthy community have been conducted under various types of environments, including churches, commercial facilities, urban plazas, parks, and streets in various scales, reflecting their unique characteristics. Third, in the process of designing a healthy and sustainable city, determination of location carries significant implications along with building a community of appropriate size, which requires multidisciplinary considerations in addition to functional approaches. Fourth, the composition and design of a modern urban community need to seek practical ways of its implementation within the concept of healing environment.

Though the upper stream basin area of Gwanpyung-Cheon in Daejeon, Korea is protected as Green Belt Zone, the stream is under constant environmental pressure due to current agricultural practices and infrastructure development in its basin area. To develop appropriate integrated water resources management plan for the stream, it is necessary to consider not only water quality problems but also water quantity aspect. In this study, Storm Water Management Model (SWMM) was calibrated and validated with sets of field measurements to predict for future water flow and water quality conditions for any rainfall event. While flow modeling results showed good agreement by showing correlation coefficient is greater than 0.9, water quality modeling results showed relatively less accurate levels of agreements with correlation coefficient between 0.67 and 0.87. Hypothetical basin development scenarios were developed to compare effect on stream water quality and quantity when Low Impact Development (LID) technologies are applied in the basin. The results of this study can be used effectively in decision making processes of urban development Gwanpyung-Cheon area by comparing basin management alternatives such as LID methods.
