기존 저수지 농업용수는 주로 논의 벼재배 용수공급을 목적으로 설계되었지만, 논 지역 타작물 재배 지원 등의 정책으로 논에서 밭으로 전작화가 증가함에 따라 농업용수의 효율적 분배를 위한 논의 전작화 패턴 분석이 필요한 실정이다. 이에 본 연구에서는 공공데이터 포털의 2019년 팜맵을 활용하여 최신 경지 현황을 파악하고, 환경부의 2007년, 2019년 토지피복지도를 이용하여 전작화 패턴을 분석하였다. 구축된 팜맵과 토지피복지도는 환경부 토지피복분류 기준 농업지역 중분류로 일치시켜 분석에 활용되었다. 논, 밭, 시설재배지 등의 농경지 이용 현황 및 전작화 추이는 전국 단위, 권역 단위로 분석되었고, 주요 시도와의 공간적 거리를 전작화 영향인자로 설정하여 DUP(Degree of Urban Proximity) 등의 지표로 그 영향을 확인하였다. 또한, 전체 경지 중 논, 밭의 면적과 증감 추이를 ACR(Area Change Rate) 등의 지표로 전작화 규모를 파악하였고, LPI(Largest Patch Index), LSI(Landscape Shape Index) 등의 지표로 개별/집단화 전작의 패턴분석을 수행하였다. 본 연구로 제시된 저수지 수혜 구역별 논의 전작화 패턴은 논 벼재배와 농업용수 수요 특성이 상이한 밭작물에 안정적 용수공급 체계 구축 등의 기초자료로 활용 가능할 것으로 생각된다.

인간활동으로 인해 서식처의 변화, 서식처의 파편화를 비롯하여 기후변화, 토지이용의 변화 등으로 생태계 생물 다양성은 빠르게 손실되고있는 상황이다. 특히 생물 다양성은 생태계 복원력에 중요한 인자로서 유역의 건전성 회복을 위해 생물 다양성을 중요한 인자로 고려하려는 경향이 커지고 있다. 유역 건전성은 주로 큰 하천에서의 친수성, 서식처, 유량 및 수질 등에 적용되어왔고 국내에서는 최근 들어 유역 건전성을 확보하기 위해 수량 및 수질관리, 환경문제 등의 해결을 위해 유역관리 차원에서 접근하려는 시도가 시작되었으나 어떠한 수단을 통해 생물다양성과 서식처 관리를 접근할 수 있는지에 대한 연구는 아직 부족한 실정이다. 이에 본 연구에서는 최근 20년 동안 도시화, 댐 건설 등 토지이용변화가 크게 발생한 금강유역(9,865 km²)을 대상으로 InVest 모델 중 서식처 가치평가 모델 (Habitat Quality Model)을 이용하여 유역의 서식처 가치를 평가하고 이를 수생태계 건강성 모니터링 자료와 비교하여 모형의 적용성을 평가하고자 한다.

This study reviews theoretical considerations and past studies about real estate prices, macroeconomic variables, and real estate policies. Monthly data from January 2003 to June 2021 are used, and a VEC model, the most widely used multivariate time series analysis method, is employed for analysis. Through the model, the effects of macroeconomic variables and real estate regulatory policies on real estate prices in Seoul are analyzed. Findings are summarized as follows. First, macroeconomic variables such as money supply and interest rates do not have a significant impact on Seoul's apartment prices. Due to the high demand for housing and insufficient supply, there is a demand for buying a home regardless of macroeconomic booms or recessions. Second, tax and financial regulatory policies have an initial impact on the rise in apartment prices in Seoul, and their influence diminishes over time. Third, anti-speculation zones are expected to decrease apartment prices through the suppression of demand. However, these zones cause a rise in apartment prices. This could be understood as a lock-in effect due to the strengthening of capital gains tax. Fourth, the price ceiling did not decrease apartment prices. These findings propose that, in Seoul, where demand is high and supply is insufficient, the supply of high-quality and sufficient housing should be prioritized over various regulations such as tax regulations, financial regulations, anti-speculation zones, and price caps. Moreover, the findings provide an implication that city-specific real estate policies should be implemented for Seoul rather than regulation-oriented approaches in public policy.

The ministry of land, Infrastructure and transport has revised the "National Land Planning and Utilization Act" in 2012. As a result, the regulation of floor area ratio for land covering two or more zoning area has been changed. This study conducted an analysis of the policy effects of changes in the criteria for the application of the floor area ratio by revising the "National Land Planning and Utilization Act". Land covering two or more zoning area means a street side commercial area and street side residential area that is generally understood. This study analyzed the policy effects in Gangnam-gu which has relatively large areas of street side commercial area and street side residential area. The 468 office building transaction cases were analyzed in Gangnam-gu from 2007 to 2017. The result shows that the office building, which has received incentive for policy changes, reported a 19.08% rise in price compared to the one that did not. It means that the economic effects of change of application standard were significant. The existing policy also served as a restriction on land use by landowners, which in turn contributed to the devaluation of the asset's intrinsic value. Therefore, this study may have contributed to the rational use of land and to provide an empirical basis for the change in policy to be assessed for its intrinsic value.

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.

This article aims to conserve greenbelts by adopting the national trust approach. This article reviews the current issues and problems in managing greenbelts in Korea. And this article redefines the function of greenbelts, and then suggests the new principles of management strategies of greenbelts. Greenbelts is to provide green open space for urban residents and to contain urban sprawl not to reserve lands for the future urban development. This article proposes basic principles for the effective management of green belts. They include (1) preserving environmental value, (2) maximizing public access to open space and environment resources, and (3) enhancing public-participation and collaboration among different groups and organizations for the management of greenbelts. These principles are closely related to those of national trust movement. This article suggests the government to adopt national trust approach (organization, funding, site selection criteria, legislation) to improve the environmental-friendly conservation and management of greenbelts in Korea.

The paradigm of the housing policy has been transformed from housing supply to housing welfare, from the policy of housing quantity expansion to the policy of customized housing welfare. The Housing Act was newly enacted to realize the new paradigm of the housing policy. The Act establishes the role of the Housing Welfare Centers in the housing welfare delivery system, but they have some difficulties in doing their role because of limited amount of centers and their manpower. The desirable and efficient model of housing welfare delivery system, therefore, is that the demand of housing welfare is discovered on local base, and that demanders can be provided housing welfare service connected to local governments or neighborhood housing welfare centers. To do so local communities should be established and activated, and the needs of housing welfare service also be discovered. This study is a exploratory one on communities' role in housing welfare delivery system in spite of some limitations based on existing theories and studies, and is significant as a new trial.

Using youth panel data, this study attempted to diagnose the effect of residential characteristics (housing type and housing type) and various household background variables on the implementation of youth NEET (Not in Employment, Education or Training), and to suggest appropriate policy directions. As a result of the analysis, it was found that young individuals residing in unfavorable living conditions such as those who rent on a monthly basis or live in multi-household, villa, or officetel settings, had a higher likelihood of transitioning to NEET. Those who received financial support from their parents were more likely to transition to NEET. Therefore, comprehensive youth NEET support policies such as customized housing and job policies according to the characteristics of NEET should be established. In particular, even though they have reached adulthood, it is shown that the likelihood of becoming NEET is very high for youth who live together with their parents without being economically independent or who receive financial assistance from their parents. In order to mitigate and prevent these young people from NEET transition, transitioning from school to the labor market should be facilitated with policy support.

본 연구는 방사성폐기물 처분시설(radioactive waste repository)의 입지를 가정하여, 처분시설이 경상북도 경주시에 발생시키는 경제적, 사회적 효과를 분석하는데 목적이 있다. 정부는 처분장 유치의 유인책(incentives)으로서 경주 지역주민들을 위하여 다양한 정책적 수단을 마련하였다. 처분시설 입지에 따른 특별지원금 3,000 억원 지원, 수거물 반입 수수료 지원(년당 50-100억원), 한국수력원자력(주) 본사이전, 양성자가속기 사업 추진 등이 그것이다. 이들 지원사업들이 가져오는 변화를 시스템 다이내믹스(System Dynamics) 기법을 적용하여 지역사회의 인구, 산업, 토지, SOC, 지방재정 등이 어떻게 변화하는지 추적해 봄으로써 도시체제의 동태성(urban system dynamics)을 이해하고 처분장 시설이 지역에 입지했을때, 미래에 발생 가능한 문제점이 없는지 밝혀내고자한다. 이를 위하여 시뮬레이션 모델링에 입지 지역의 특성과 현황을 반영하여 처분장입지에 따른 지역의 동태적인 변화과정과 경향을 추정해 보고, 현재 예정되어 있는 지원사업이 충분한지, 이외에 다른 정책적 지원이 필요한지를 알아본다. 본 연구의 의미는 이처럼 경주지역 주민들이 처분장의 지역입지를 만족스럽게 행각하고 소외감 없이 생활을 영위할 수 있도록 정책적 지원 프로그램을 작성하는데 기초가 되는 연구라는 점에 있다고 하겠다.
