The purpose of this study is to introduce the design and early implementation results of Choice Neighborhoods(Choice) initiative, which is the most recent version of public housing policies in the United States designed and implemented under the Obama administration. The Choice initiative aims to support a wide range of strategies locally driven to address problems in disadvantaged neighborhoods with an emphasis on a comprehensive approach to transforming those neighborhoods. In this study, first, I briefly review the history of public housing policies since 1937, particularly focusing on limitations of HOPE VI(Housing Opportunity for People Everywhere) projects to understand the context behind the advent of the program. Second, I introduce the overall design of the Choice program and point out how this programs' design differs from previous public housing programs by reviewing the literature on federal guidelines for the Choice program. This study particularly focuses on introducing social services given to existing residents in public housing and their neighborhoods in redevelopment processes. These social services are intended to address poverty-related problems that public housing residents often confront, to help them break out of the cycle of poverty, and to minimize the negative impacts of relocation triggered by redevelopment. Third, to examine how this program has been implemented and has revealed limitations so far, I review an interim evaluation report based on five cities. This study ends with discussing policy implications for public housing providers and housing policy-makers in South Korea.

이 연구는 가구소득수준과 이사간 지역의 소득이 일치하지 않는, 교차소득 주거입지결정 요인에 관하여 분석하였다. 연구대상지는 미국 중서부, 오하이오 주에 위치한 프랜클린 카운티로서 1999년 오하이오 주립대학에서 자가거주 가구들을 대상으로 실시한 주거입지선택 결정요인에 관한 설문자료를 바탕으로 분석하였다. 연구방법으로는 설문에 참여한 가구와 프랜클린 카운티 내의 근린지구의 소득수준을 저, 중, 고소득으로 나눈 후 각 가구계층별로 교차소득 주거입지결정 요인에 관하여 다항로지스틱 회귀분석을 실시하였다. 분석결과에 따르면 중산층 가구가 상위계층 지역으로 이주하는 이유는 학군과 관련이 있는 것으로 나타났으며 저소득계층 지역으로 이주하는 이유는 투자목적 때문인 것으로 나타났다.

The objective of this paper is to use Geographical Information Systems for identifying Digital Divide in Riyadh Neighborhoods, Saudi Arabia. Geo-database was created that includes Streets, Neighborhoods, ICT Access Data and Coverage Map for Riyadh. We used QGIS and overlay for analysis, intersection selected as tool for this paper. The results indicate that after analyzing the use of information communication technology in all regions of the Kingdom it turns that Riyadh, Ash Sharqiyyah and Makkah in average with percentage 50%, While Al Jawf, Al Madinah, and Najran are the least with percentage 42%. Then we focused on Riyadh to analyze the digital divide because it is the capital of Saudi Arabia and occupations the highest percent of communications towers in the KSA due to population density. Regarding coverage of the 4G, the neighborhoods at the center have recorded very high coverage score. While neighborhoods at the edges of the city have low values of coverage score. Same for 3G, it is more intense in the center and the coverage percentage is higher than 4G. For 2G we found it had the highest coverage compared to 3G or 4G

The main object of this paper is to prove several inclusion relations associated with (j, ${\delta}$)-neighborhoods of various subclasses defined by Salagean operator by making use of the familiar concept of neighborhoods of analytic functions. Special cases of some of these inclusion relations are shown to yield known results.

본 연구는 청소년에 대한 빈곤의 영향을 주로 가족의 측면에서 연구하였던 기존의 관점에서 탈피하여, 빈곤청소년이 거주하는 지역사회 환경의 위험성과 폭력성에 주목하였다. 즉, 본 연구는 빈곤으로 인해 더 위험한 환경에서 거주하게 되는 청소년이 일반 청소년보다 폭력에 더 많이 노출되는지를 살펴보고, 이것이 그들의 우울과 불안을 높이는지 분석하였다. 분석 자료로 '한국청소년패널데이터' 중2 패널자료 중에서 3-5차년도 종단데이터가 활용되었으며, 통계방법으로는 구조방정식모형이 이용되었다. 분석 결과, 청소년의 빈곤 자체가 폭력피해 경험을 직접적으로 증가시키지는 않았으나 빈곤으로 인해 위험한 지역사회 환경에 거주하게 됨으로써 더욱 많은 폭력피해와 두려움을 경험하게 되며 이는 우울 및 불안으로 이어지는 것으로 나타났다. 이 결과를 바탕으로 청소년에 대한 빈곤의 부정적 영향을 줄이는 데에 지역사회의 역량 강화의 중요성을 함의로 지적하였다.

In this paper, we introduce the concepts of pre convexity neighborhoods, c-concave functions. We study some properties for c-convex functions, and characterize c-convex functions and c-concave functions by using the preconvexity neighborhoods.

The purpose of this work was to apply geographical information system (GIS) for geostatistical analyzing by selecting a semi-variogram model to quantify the spatial correlation of the population distribution with residential neighborhoods in the both sides of Mosul city. Two hundred and sixty-eight sample sites in 240 ㎢ are adopted. After determining the population distribution with respect to neighborhoods, data were inserted to ArcGIS10.3 software. Afterward, the datasets was subjected to the semi-variogram model using ordinary kriging interpolation. The results obtained from interpolation method showed that among the various models, Spherical model gives best fit of the data by cross-validation. The kriging prediction map obtained by this study, shows a particular spatial dependence of the population distribution with the neighborhoods. The results obtained from interpolation method also indicates an unbalanced population distribution, as there is no balance between the size of the population neighborhoods and their share of the size of the population, where the results showed that the right side is more densely populated because of the small area of residential homes which occupied by more than one family, as well as the right side is concentrated in economic and social activities.

대부분의 국내 아파트단지는 서비스 공급의 자족성, 자치, 폐쇄성이 특징인 빗장주거단지(gated community)라고 할 수 있다. 오늘날 동네에 끼치는 영향은 고려하지 않은 채 기존의 아파트단지 담장에 더해 단지 내부로 외부 보행자 출입을 막는 차단문이 설치되면서, 아파트단지의 폐쇄성은 더욱 강화되고 있다. 이러한 빗장주거단지의 폐쇄성 강화가 근린의 사회적 지속가능성에 끼치는 영향을 평가하기 위해 근린 내 주거유형을 주거지 폐쇄의 정도에 따라 저층주거지, 일반 아파트단지, 차단문이 설치된 아파트단지로 나누고 설문을 통해 각각의 사회적 지속가능성을 평가하였다. 분석 결과 차단문의 설치는 사회적 지속가능성 중 삶의 질 관련 지표를 높이는 효과는 있으나, 일반 아파트단지보다 포용성 지표를 대폭 낮춤으로써 근린의 사회적 응집력을 낮추는 것으로 나타났다. 폐쇄성이 강화된 새로운 아파트단지는 기존 아파트단지와 저층주거지 간에 유지되어 온 공존 질서를 뒤흔들고, 근린 내 공간적·사회적 분리를 강화하고 있다.

By making use of the familiar concept of neighborhoods of analytic functions, we prove several inclusion relationships associated with the (n, ${\delta}$)-neighborhoods of certain subclasses of p-valent analytic functions of complex order with missing coefficients, which are introduced here by means of the Saitoh operator. Special cases of some of the results obtained here are shown to yield known results.

In the present investigation, by making use of the familiar concept of neighborhoods of analytic and multivalent functions, we prove several inclusion relations associated with the (n, ${\delta}$)-neighborhoods of certain subclasses of analytic functions of complex order, which are introduced here by means of the Al-Oboudi derivative. Several special cases of the main results are mentioned.
