  • The development of science and transportation technology leads to the increase of inter - city networks that play an important role in urban growth. Overall, numerous studies based on network theory pay attention to positive effects of urban network on urban growth. However, some studies have pointed out the negative effects of inter-city interactions such as straw effects. This implies that the network between cities may not be positively correlated with urban growth, and that the direction of the influence may vary from a certain threshold, such as the marginal utility curve. In this context, the purpose of this study is to measure the impacts of network with central city on urban growth in the capital region and examine the relationship between urban network and growth. Two multiple regression models are employed with changes in population and employment as dependent variables. The urban network index and other control variables are used as independent variables. Especially, the urban network indexes are used in quadratic forms to examine non linear relations with urban growth such U-shape or an inverted U-shape. The results show that the relationships between networks with the central city and urban growth are not a simple linear, and the influence can be changed from the critical point.

  • 이상에서 본 연구는 1960년 이후부터 1985년까지의 인구규모와 그 변동의 특질을 농촌에서 도시로의 인구이동현상과 관련하여 검토해 보았다. 아울러 분해시계열방법을 이용하여 농촌인구유출과 농정과의 관계도 고찰하였다. 그리고 적정모델을 추정하여 2,000년까지의 농촌 및 농가인구도 예측해 보았다. 결론적으로 말해서 인구구조의 변화측면에서 농촌인구와 농가인구는 1965년부터 감소하기 시작하여 1975년 이후부터 급격히 감소하였다. 농촌인구의 급격한 감소는 농촌 인구의 자연감소로 인한 요인보다는 도시로 유출되는 인구이동의 요인이 더 크게 작용한 것으로 나타났다. 농촌에서 도시로의 인구유출과정에서 유입지의 분포를 보면 도시지역 중에서 서울, 부산, 경기지역으로 인구가 집중한 것으로 나타났다. 특히 70년대에는 서울 부산 등 대도시 지역으로 직접적인 이동이 있었으나 80년대에 들어와서는 대도시 지역으로의 직접적인 유입보다는 주변지역으로의 유입이 점차 증가함으로써 농촌에서 대도시로의 유입형태가 주변도시로의 유입형태로 변화되고 있다. 농촌인구의 유출을 농업생산과 관련시켜 볼 때 농업노동력의 수요가 확대되는 6월 이후에 유출인구는 점차 줄어들고 있으며 3월에 가장 많이 유출하는 것으로 판명되었다. 60년대 이후 농업정책과 농촌인구의 유출과의 관계를 분석하기 위해 순환변동을 도출하였으며 2-3차 개발계획기간을 제외한 기간에 있어서 농촌부문의 상대적 저위성이 농촌인구의 유출을 자극한 요인으로 작용했으며 이러한 사실은 농업정책의 불균형적 시행이 직 간접적으로 영향을 미친 결과라 하겠다. 끝으로 농촌인구의 유출을 포함한 한국농업의 근본적인 문제는 도농간 상대적 소득 격차에 있다고 보고 농촌지역의 개발을 서울이나 수도권, 대도시권의 비대화를 막기 위한 방편 또는 공업화 우선정책의 반작용으로 본 과거의 정책성향을 극복해야 한다는 점이다. 따라서 도농간 소득격차의 문제를 농업정책의 중심과제로 삼고 농촌지역의 자원을 보다 효율적으로 이용함으로써 나라의 경제적 효율성은 물론 형평성을 높인다는 시각에서 농업정책을 다루어야 할 것이다.

  • Reports on population movement(2000-2030) by the National Statistical Office show that the number of elementary school age population will be decreased by 1.4million from 2005 to 2020. It will effect both school size and the policies for school facilities, which have focused on downsizing class as the high standard of OECD nations. As the unfolding evidence is emerging that a number of schools and classes will be emptied out by 2030. This study aims at developing a objective and scientific device for estimate the number of students at future and evaluating the validity of school establishment. In doing so, it explores the relationship between the changing factors and the number of students. It proposes four factors such as the changes of population, the fertility rate, the number of apartment occupant and movement of population. As the result of the statistic analysis on the correlation coefficient, it finds out that the change of apartment occupant has a close correlation with the change in the number of student and has a deep effect on the establishment of school. Finally, it shows the construction of school according to urban developments during 1999-2008 in Incheon Metro-City. This study would help the authorities to expect the future number of student and to restrict overbuilding of surplus classes, finally the reasonable expenditure for school facilities.

  • Accessibility of urban green space, as an important index of evaluating the service level of urban green space, not only shows the resident's access to green space, but also reflects the environment quality of urban living. Since the quantity, area and space distribution of the patches in urban green space directly affect the function of urban green space and the quality of urban environment, the research on the accessibility of urban green space holds great significance to improve the service of urban green space and the living environment quality. Based on GIS software, this research uses the road network and the population distribution data of Nanjing's city proper to conduct quantitative analysis of the accessibility of park green space and the convenience for residents to travel under different forms of transportation. After the case analysis, the author tests the application of road network in studying the accessibility of urban park green space and proposes a GIS-based method to study the accessibility and the rational layout of urban green space.

  • Modern cities need to revitalize the downtown area, which is declining due to population decline, economic recession, and deterioration of the residential environment, economically, socially, and physically by introducing and creating new functions. In addition, the hollowing out of the existing city center is getting worse due to the development of the outskirts of the city. Therefore, the discussion for the development of urban regeneration is the core task of modern cities. This study analyzed based on a basic understanding of urban regeneration projects, and through this, the problems of domestic urban regeneration projects were derived. In addition, the problem factors and major improvement plans of the urban regeneration project were analyzed from the expert's point of view using the AHP analysis technique. Based on this, the purpose is to present policy alternatives for the future development of urban regeneration projects. The problems derived to present the policy alternatives and improvement directions of the urban regeneration project were classified into problems related to goal achievement, problems related to the business itself, and problems related to project results. It was subdivided into sub-categories. This study analyzed the problem factors and major improvements from the expert's point of view by using the AHP analysis technique for the problems of the urban regeneration project. Based on the AHP analysis results and experts' opinions, five policy alternatives for the development of urban regeneration projects were presented.

  • 도시의 개발과 고밀화는 도시공간의 기온이 주변지역보다 높아지는 도시열섬(Urban Heat Island)현상의 원인이 되고 있으며, 도시열섬현상은 기후변화와 함께 그 강도가 증가하고 있다. 이와 더불어 여름철 도시의 대기온도가 상승할 때 소득이 낮은 계층, 고령인구, 건강에 문제가 있는 사회적 취약계층은 높아진 열환경에 대처할 수 있는 능력이 부족하다. 따라서 본 연구의 목적은 서울시의 열섬지역을 공간통계 기법인 Hotspot 분석을 통해 도출하고, 로지스틱 회귀분석을 활용하여 열섬지역의 물리적 환경과 인구 및 사회경제적 특성을 분석하는 것이다. 서울시 423개 행정동을 대상으로 동별 평균 대기온도를 이용하여 도시열섬 Hotspot 분석을 실행한 결과, 서울시 중구, 종로구, 용산구, 영등포구에서 도시열섬 지역이 집중적으로 분포하는 것을 확인하였다. 로지스틱 회귀분석을 통해 열섬지역의 물리적 환경 특성을 분석한 결과, 주거시설 연면적 비율, 상업시설 연면적 비율, 용적률, 불투수면 비율, 정규화식생지수(NDVI)가 열섬지역에 영향을 미치는 유의한 변수로 나타났다. 또한, 열섬지역의 인구 및 사회·경제적 특성을 고려한 열환경 취약지역을 분석한 결과, 기초생활수급자 비율, 독거노인 비율, 기초생활수급을 받는 독거노인 비율 등이 유의한 변수로 나타났다. 본 연구의 결과는 도시열섬현상에 영향을 미치는 물리적 환경변수를 도출하고 사회적 취약계층의 공간적 분포와 도시열섬지역이 중첩되어 있는 지역을 판별함으로써 향후 취약계층을 고려한 도시 열환경 설계와 정책 개발에 있어 시사점을 제공할 것으로 기대한다.

  • The financial incomes of urban rail transit authorities have been only from the fares. In order to increase the customers and expand the scope of enterprise, it is the most feasible mean to develop the area around the stations. Current experiences have confronted the excessive concentration of population and traffic congestion due to the lack of systematic planning and the excessive focus on the business. This study reviewed the necessity of the impact area around the urban rail transit stations by the organizational analysis for the urban rail transit authorities, and reviewed domestic/foreign cases. Finally, This study suggested the strategy for the development of impact area around the urban rail transit stations.

  • This study aims to investigate the urban regeneration policies in Japan especially focusing "New Town" regeneration. New Town projects were launched in major Japanese cities, aiming to form a designed urban housing area and a mass supply of quality housing, in order to solve the lack of housing and urban sprawl which became a serious issue due to the over-concentration of population and industries in the city during the period of rapid economic growth. Tama New Town and Kohoku New Town are well-known development projects in 1970s and 80s; They attract wide attention again as urban regeneration policies focusing on a Smart city as well as Private-Public Partnership.
