The Zone-Based. landuse Information System(ZBLIS) is an useful information system for city administrators and researchers for planning and analysis. The purpose of this study is to establish concept and methodology of the ZBLIS. The concept of Planning Analysis Zone(PAZ), as a basic unit of analysis, was defined to establish the ZBLIS. Then, various PAZs were suggested through a case study of Pohang city. Also, various useful attribute data were recommended in this study for ZBLIS. Digital Maps were used to establish ZBLIS. Among 730 subcategory items in the Digital Maps, some necessary items were selected for ZBLIS. A 84 items was recommended to be use of the ZBLIS. And 250 more items were recommended for more detailed analysis of the ZBLIS. While previous studies of landuse infonnatiom systems have focused on establishing Parcel-based Landuse Infonnation Systems, it is meaningful that this study is trying to recognize the significance of the ZBLIS and suggest the concept and methodology of the ZBLIS.

As accessibility to health-care service in less populated rural areas is geographically limited and demand for public health-care by the aging is increasing, a new approach for health-care service such as a home care service is becoming more popular. For a home care service, health-care personnels directly visit to location of health-care clients. Such changes in provision of health services require developing innovative and scientific approaches for efficient allocation of health resources and managing services by public health-care organizations. The purpose of this study is to formulate a location model for visiting health-care districting for the rural elderly and to develop an Automated Zoning Procedure (AZP) to solve this model. Mobility, workload balance and contiguity criteria are considered in the model. Three different objective functions are evaluated; 1) minimizing the sum of network distance between the unit areas in a district, 2) maximizing spatial interaction between the unit areas in a district, and 3) minimizing tour distance that visits each unit area exactly once in a district. The AZP for solving the model is developed and applied to a rural area. The application results demonstrate that the AZP can generate different districting systems for each objective functions.

The aim of this article is to critically review the PRC's policies related to its minority nationalities with a special emphasis on the identification of minority nationalities(minzuzhibie) and the establishment of minority nationality autonomous regions(minzuzizhiquyu), as a part of national integration Process. In that Process, the intentional application of the criteria on nationality identification, the establishment of minority nationality autonomous regions, the population redistribution policies and the gerrymandering by the government played an important role in the deconstruction of traditional basis of identities and the territorialization of ethnicity. The goals of government have been the redefinition of 'Chinese', the the invention of 'Chinese nationality(zhongguominzu or zhonghuaminzu)'and the unification of its national territory. However, these have led to the unexpected result by creating the new ethnic-territorial identities along with the nationalities identified and the territories defined by the government.

한강 "수변구역"에서 비점오염물질의 공공수역 유입을 억제하기 위한 다양한 방법들 중에서 보편적이고 자연친화적인 방법은 다양한 생물의 서식공간이며, 동시에 본류로 유입되는 과정에서 수질을 정화시키는 수질개선 공간인 수변완충구역, 또는 지대를 설정하여 관리하는 것이다. 그러나 이러한 수변완충지대 효과 분석 및 설정에 관한 연구는 국내에서 아직 수행되지 않았다. 본 연구의 목적은 수변구역의 자정능력을 높이는 것은 물론 그 밖의 하천 연안에서 비점오염물질의 차단과 처리능력을 증진시키고 수변 생태계의 서식처 보전 및 복원을 위해서 수변완충지대의 수질정화 기술개발과 생물다양성을 창출하는 수변완충지대 조성 기법을 개발하는데 있다. 본 연구에서는 기존 수변완충지의 추가적인 조성과 보완, 시험완충지 생태구조 및 기능 기초조사, 시험완충지 오염부하 저감효과의 실험 및 분석, 수변완충지대 설치 구상 등의 연구를 수행하여 수변완충지대 조성 시 설정 폭을 산정할 수 있게 하였다. 수행 지역은 한강수계 지역으로 남한강 수변인 경기도 양평군 병산리에서 실시하였으며, 잔디와 갈대, 갯버들, 혼합지역, 자연그대로의 상태(대조지역)의 5 구역으로 구분하였고, 거리별, 깊이별 샘플을 채취하여 유입수에 대한 오염물질 제거효율을 도출하고, 이를 이용하여 수변완충지대의 설계 시 필요한 유역의 폭, 면적, 길이 등과 같은 설계인자를 도출할 수 있도록 하였다.

The purpose of this study is to examine a monitoring method, management zones, and maintenance strategies for water friendly facilities in urban streams after the completion of ecological restoration projects. Maintenance monitoring items are composed of 'use space& facilities', 'trails& bike roads', 'access', and 'boards'. The evaluation standards of water friendly facilities are 'maintenance conditions', 'safety', and 'usage level' which are rated as 'good', 'moderate', and 'poor'. Through a field survey and evaluation of 15 stream sections in Jeonjucheon,the management levels of each water friendly facility are determined as 'priority maintenance', 'general maintenance', 'maintain/remove', and 'remove'. Based on the evaluation results, management zones and maintenance strategies are proposed for each stream section. As a results, the stream sections of J2, J3, J4, and J9 which have 5 to 9 facilities with 'priority maintenance' are determined as 'intensive management zone'. The stream sections of J5, J6, J7, J8, J11, and J14 which have 1 to 3 facilities with 'priority maintenance' are determined as 'regular management zone'. The stream sections of J1, J10, J12, J13, and J15 which have no facilities with 'priority maintenance' are determined as 'minimum management zone'. The process of monitoring & evaluation system and determining management zones can be applied to establish a systematic maintenance plan for water friendly facilities by participation of governance in the future.

부산항 신항은 현재 21개의 선석 규모에서 2030년까지 총 40선석까지 확대할 계획을 갖고 있다. 항만의 확대에 따라 선박 통항량 증가가 예상되며, 이를 대비해 해상교통관제도 해상교통량을 기반으로 집중관제구역을 설정할 필요가 있다. 본 연구는 부산항 신항을 대상으로 해상교통위험도 모델을 이용해 위험구역을 정량화하고 집중적으로 관제가 필요한 구역을 도출하는 것을 목적으로 한다.

This study analyzed the influencing factors for urban redevelopment projects with a relatively long project duration in the context of Seoul's increasing urbanization rate and aging. Among the business areas that have been designated since 2005 and have been approved for the management and disposal plan of the entire Seoul area, 75 business areas have been set as targets. A hedonic price model was used to analyze the project area, economic, and locational characteristics as independent variables with the project duration from designation of zones to approval of management and disposal plans as dependent variables. As a result of the analysis, the smaller the project area, the larger the area occupied per union member, the larger the land price change rate, and the smaller the KOSPI index, the shorter the required period. This study has the distinction of empirically analyzing the effect of characteristic variables considering size and economic and locational characteristics on period. It provides implications that the area of the business area, the number of union members, and economic conditions should be considered when establishing a business area.

Recently, the Korean government has amended the "National Territory Planning Act" by adding criteria to designate the Impact Fee Zone on the basis of the population increase rate. Taking the Dongtan Newtown in Hwasung City as the case, the study first tries to apply a grid analysis method to figure out the cells that exceed the legal population increase rate criteria. Then, the study, for rather a practical purpose, introduces a scenario analysis that tries to envelope the cells into a spatially contiguous groups based on their degrees of stepwise adjacency by cell buffer formation. By overlapping the selected cell groups chosen by such stepwise scenarios over the actual zoning map of land-uses for the vicinity, it seems clear that the chosen areas rationally coincide with those residential blocks and commercial areas with the high population density in the Newtown.

우리나라는 연중 강우량의 계절적 편중이 심하여 약 2/3이 6월-9월에 집중하는 기상학적 요인과, 국토의 약 70%가 산악지역으로 되어있는 지형학적 요인 등 홍수에 취약한 자연특성을 갖고 있으며, 특히 하천, 도시 저지대, 해안 및 산지에서는 홍수범람, 내부배제 불량, 해일, 산사태 등으로 매년 많은 인명피해와 재산상의 손실이 크게 발생하고 있다. 또한 최근 발생하고 있는 이상기후 현상과 각종 개발사업으로 인한 불투수면적의 증가 등으로 인해서 극한 홍수의 발생빈도가 높아가고 있으나, 기존 수방시설물의 홍수배제능력 부족 등으로 매년 많은 피해를 입고 있는 실정으로, 구조적인 대책만으로는 재해피해를 경감시키는데 한계가 있음을 인식하여 구조적 대책과 더불어 토지이용규제 및 개발규제, 홍수터관리, 홍수예경보 등 비구조적 재해대 비능력 향상이 시급한 현황이다. 우리나라의 경우, 구조적 수방기술의 발전은 비교적 높은 수준에 도달해 있지만, 구조적 대책에 비해 비구조적 대책의 개발 및 적용은 미흡한 형편이므로, 비구조적 홍수대책의 종합적 정비 및 효율적 운영방법 필요하다. 따라서 본 연구에서는 홍수유형별 발생원인별 대표적인 비구조적 홍수대책을 국내외 적용사례를 조사하여 분석하고, 비구조적인 홍수방어대책들에 대한 장단점 및 적용성 등의 정성적 평가를 실시하였다. 국내 여건에 적합한 홍수위험구역 설정방안을 제시하고자, 국내의 다양한 하천공간 확보를 위한 관련규정인 하천구역, 홍수관리구역, 수변구역, 상수원보호구역, 친수구역, 홍수위험구역, 자연재해위험지구, 방재지구 등에 대하여 조사하였으며, 국외 사례로 영국의 홍수위험구역 평가제도, 미국의 홍수터 관리 프로그램, 호주의 하천공간 분류 기준, 일본의 하천공간 설정 기준 등에 대한 고찰을 수행하였다. 또한 국내 홍수보험 제도의 문제점 분석 및 제고방안을 제시하고자, 현재 소방방재청 주관으로 시행되고 있는 풍수해보험제도에 대한 조사 및 분석을 실시하였으며, 미국에서 시행되고 있는 국가홍수보험프로그램, 프랑스의 자연재해보험, 스위스의 자연재해보험풀 제도, 일본의 홍수보험제도에 대하여 심층적인 고찰을 수행하였다.
