Korean Government has introduced the regulation in apartment housing construction by supplying a physical mixture type between a (public) rental – and sale housing unit in order to address residential segregation/isolation and hence to accomplish social integration. However, the effectiveness of policy intervention for social integration is still questionable since spatial segregation in physical mixture leads to social conflict among the residents in a rental/sale unit. This study aims to suggest the policy implication on public rental housing policy for social integration in an apartment complex by investigating factors affecting the preference for physical mixture-layout types for 10 cases of apartment complexes provided by the city of Daegu, Korea To do this, we categorized physical mixture-layout types into separation, adjacency, site-mixture, and building-mixture. Empirical models are analyzed by multinomial logit model to quantify the statistical significance and magnitude of variables. The results showed that neighborhoodship has a negative effect on the preference for separation, adjacency, and building-mixture when the reference variable site-mixture type. Based this result, a site planning method for improving the level of neighborhoodship of residents should be considered in order to ensure the effectiveness of physical mixture in apartment complex.

안애림(Ae-Lim Ahn),한용진(Yong-Jin Han),박세영(Se-Young Park),남지순(Jee-Sun Nam) 한국정보과학회 2012 정보과학회 컴퓨팅의 실제 논문지 Vol.18 No.2

본 연구에서는 웹 문서에 실현된 사용자 의견문장을 분석하는 오피니언 마이닝(Opinion Mining) 연구의 일환으로, 특히 함께 공기하는 자질 명사에 따라 그 극성 값이 달라지는 '비결정 오피니언 어휘'의 처리를 위하여 도메인을 '맛집'으로 한정한 후 이러한 오피니언 어휘와 공기하는 도메인 키워드의 목록을 결정하고, 이를 부분문법그래프(Local Grammar Graphs) 모델을 이용하여 기술하였다. 이러한 비결정 오피니언 어휘에 대한 어휘·통사적 기술이 수행됨으로써 현 단계의 오피니언 자동 분류 시스템의 성능을 향상시킬 수 있음을 확인하였다. This study aims at classifying semantic polarity (i.e. Positive, Negative or Neutral) of opinion sentences from web documents, especially including "Non-deterministic" opinion words. To analyze their polarity in opinion sentences, we focus on the online reviews about restaurants and describe the relation of domain key words and non-deterministic opinion words by Local Grammar Graph(LGG) formalism.

장애 교육시설 현장조사를 통한 범죄예방 환경설계요소 실태분석

안용진(Ahn, Yong-Jin) 한국셉테드학회 2019 한국셉테드학회지 Vol.10 No.3

학교시설 범죄예방을 위한 환경설계 원칙 적용은 이미 학문적으로나 실무적으로 활발히 논의된 바 있으나, 상대적으로 장애학생 교육시설 공간에 초점을 둔 범죄예방 환경설계 원칙 적용 및 평가에 대한 연구는 제한적으로 수행되었다. 본 연구는 범죄예방 환경설계 관점에서 특수학교와 특수학급으로 구분된 장애교육 시설의 방범환경을 현장방문 조사를 통해 평가하고 두 교육시설의 현황 차이를 통계적으로 검증함으로써 향후 실무적 차원에서 장애교육 시설 범죄예방 환경설계를 구체화하는데 기초 자료를 제공하고자 한다. 장애영역, 교육과정, 권역별로 구분된 20개 장애교육 시설을 대상으로 학교주변 및 학교공간 현장방문 조사 결과, 전반적으로 특수학교가 특수학급에 비해 상대적으로 방범환경이 우수한 것으로 평가되었다. 세부적으로, 담장(학교경계), 후미진 공간(건물외부), 화장실(건물내부) 공간의 경우 통계적으로 유의미한 차이가 확인된 반면, 나머지 공간영역의 경우 특수학교와 특수학급 사이에 통계적으로 유의미한 차이가 도출되지 않았다. 따라서 특수학급의 방범환경 개선 및 범죄예방 환경설계 적용에 있어 해당 공간영역을 우선적으로 고려할 필요가 있다. Principles of crime prevention through environmental design (CPTED) for educational facilities are fairly defined in academia and practice, but relatively little is known about the adaptation and evaluation of CPTED targeted at the disabled students. From the perspective of CPTED, this study aims to provide basic and practical knowledge on educational facilities for the disabled students by conducting field evaluation and statistical analysis on the difference between special schools and special classes. The results from field evaluation on 20 educational facilities (9 special schools and 11 special classes) in Korea reveal that anti-crime conditions in special schools are normally better than those in special classes. The statistical significance of anti-crime conditions between special schools and special classes was found in wall (school edge), secluded dead space (outside building), and restroom (inside building), whereas the statistical significance was not found in other spaces. Therefore, priority consideration on such spaces will be given to the adaptation of CPTED principles on special classes.

거주지 교통사고 공간적 집중이 주거환경 만족도에 미친 영향

안용진(Ahn, Yong-Jin) 한국도시설계학회 2016 도시설계 : 한국도시설계학회지 Vol.17 No.2

주거환경 만족도 향상에 기여하는 거주지 환경특성은 그동안 다수의 연구에서 논의된 바 있으나, 일상 생활공간 내 존재하는 다양한 안전 위험요인이 미친 부정적(-) 영향에 대한 실증적 검토는 아직까지 미흡한 실정이다. 본 연구는 다년도 서울시 공공데이터와 GIS 공간분석 기법을 활용하여 거주지 교통사고 지점의 공간적 집중이 주거환경 만족도에 미친 영향을 규명하는데 그 목적이 있다. 서울시 25개 자치구 거주민 약 100,000명을 대상으로 수행한 다수준 분석 결과, 해당 자치구의 재정자립도(p<0.05), 사회환경 만족도(p<0.01), 녹지지역 면적비율(p<0.05) 모두 주거환경 만족 여부에 통계적으로 유의미한 영향(+)을 보였으나, 공업지역 면적비율(p<0.01), 교통사고 노출 위험도 측정 변수인 교통사고 핫스팟 면적비율(p<0.01)은 예상대로 주거환경 만족여부에 부정적 영향(-)을 보였다. 따라서 거시적 측면에서 일상 생활공간 내 교통사고 집중지역에 초점을 둔 교통사고 위험도 완화를 위한 생활안전 전략은 거주민의 주거환경 만족도를 증가시키는 효과적인 수단으로 정책결정 과정에서 반영될 필요가 있다. Previous studies have often discussed the positive effect of local environments on residential satisfaction, whereas empirical evidence on the influence of risk factors is still insufficient. Employing multi-year public data (2010-2014) and GIS analysis, this study tests whether and to what extent spatial cluster of traffic incidents affects individual evaluation of residential environment. The results from multi-level analysis on 100,000 residents living in 25 districts in Seoul revealed that fiscal self-reliance ratio (p<0.05), social environmental satisfaction (p<0.01), and proportion of green area (p<0.05) were positively associated with residential satisfaction. However, as expected, the percent of industrial area (p<0.01) and traffic incident hot-spot area (p<0.01) indicated the negative influence at the statistically significant level. Based on those findings, urban safety policy strategies for mitigating the risk of traffic incidents spatially clustered at the macro scale can be conceived as an effective way which might be able to practically contribute to improving the level of residential satisfaction.

Relationship between street-connectivity and multi-family residential parcel values

안용진(Ahn, Yong-Jin) 도시정책학회 2017 도시정책연구 Vol.8 No.2

This research aims to examine the effects of urban environmental factors on land values, comparing with two development projects (Bun-dang and Pyung-chon) in Korea. The primary interest of this research is to assess the performance of urban design characteristic which emphasizes the compact development and land use mix to improve residents’ accessibility to urban facilities. The analysis is conducted by measuring the relationships between the values of multi-family residential parcels and the access to transit and other uses (park, office, retail, and education uses) as well as their comparative location in the city. The proximities to five uses and subway stations are estimated using GIS program. Parcel level GIS data and land value data assessed in 1996 and 2003 are used to measure such relationship. The findings indicate that multi-family residential parcel values are significantly correlated to the proximity to education and park uses. The characteristics of street network are significantly related to the chronological change of multi-family residential parcel values as well. The direction of the relationships, however, varies by the condition of urban environmental factors.

도시규모와 사회 질(Social Quality) 지표가 여성의 주관적 건강상태에 미치는 영향

안용진(Ahn, Yong-Jin) 한국도시설계학회 2014 도시설계 : 한국도시설계학회지 Vol.15 No.4

본 연구는 도시규모와 사회 질 지표가 여성의 주관적 건강상태에 미치는 영향을 규명하여, 건강도시와 여성친화도시 개념을 연계한 공간적 정책 함의를 제시하는데 목적이 있다. 이를 위한 실증모형은 여성가족패널조사와 전국 230개 지자체별 사회 질 지표 자료를 기반으로 구축되었으며, 주요 설명변수는 개인/가구특성과 거주지 사회/공간 환경특성을 반영한 사회 질 (제도역량/시민역량/건전성) 지표로 구성되었다. 순서화 된 종속변수의 이산성 및 다항 선택성을 고려하고 설명변수의 영향정도를 정량적으로 분석하기 위해 순서형 로짓 모형을 적용한 결과, 사회 질 지표 모두 여성의 주관적 건강상태에 유의미한 영향을 보였다. 사회 질 지표가 여성 건강에 미친 영향은 도시규모에 상관없이 일관된 영향관계(+)를 보이고 있으나, 통계적 유의성과 하위지표의 영향정도는 도시규모별로 차별화 된 결과를 보였다. 특히, 사회 질 관련 지표 중 건전성 지표가 상대적으로 중요한 것으로 확인되었다. 따라서 여성친화도시의 구체적인 성능지표로서 여성의 주관적 건강상태를 효과적으로 증진하기 위해서는 도시규모의 차이를 고려하고 건전성 지표(범죄등 사회안전망) 향상에 초점을 둔 공간 정책을 우선적으로 고려할 필요가 있다. This study describes policy implications for designing healthy communities and female-friendly environments by exploring the influence of urban size and social quality on self-rated health status of women in Korea. An empirical test was conducted by combining disaggregated data from the Korean Longitudinal Survey of Women and Families and aggregate data, including the Census and Social Quality Index. Explanatory variables consisted of individual and household characteristics and social environments (soundness, citizenship, and system). To quantify the specific roles of such factors, I applied an ordered logit model to address the nature of ordered responses: multiple, discrete choices. As a result, I found that urban size and social quality have a significant impact on self-rated women’s health. While three indicators for social quality consistently and positively affect women regardless of urban size, both their statistical significance and impact differ with urban size. Notably, the relative importance of soundness is higher than others. To effectively enhance self-rated health of women, policy priority should be given to improving the level of social security while considering the difference in urban size.

The position of Korea in a global society has changed from an ODA recipient into a donor country. Korea’s experience in urban development that has accumulated by dramatic economic growth over the last several decades is often highlighted as a benchmarking model of developing countries in terms of efficiency. Given the expectation that international development cooperation projects will increase continuously, this study suggests objective, rational frameworks by identifying indicators and assessing the weight of each indicator. We firstly conducted in-depth interviews with selective ODA practitioners to identify indicators. Next, using AHP method, we analyzed relative importance of indicators based on the expert survey specialized in urban development/infrastructure. Results showed that the potential of national interest(0.384) ranks as an item with the highest weight at the first level which is followed by effectiveness(0.277), sustainability(0.22), and efficiency(0.119). Regarding overall composite weight, business abroad of domestic company(0.116), project implementation(0.104), and international trust-building(0.095) were highlighted as a vital item. Based on those findings, it is expected that the future demand for ODA projects will stem from national economic benefits rather than from project efficiency. Therefore, both systematic coordination for project implementation and collaborative framework for partnership are necessary to successfully fulfill project outcomes.

주택공급 우선순위에 따른 신혼가구 주택 구매의향 영향요인 차이 분석

안용진(Ahn Yong Jin),김주현(Kim Ju Hyun) 한국주거환경학회 2016 주거환경(한국주거환경학회논문집) Vol.14 No.3

This study aims to suggest policy implication on a stable household settlement of the newlyweds, as a potential demander of the housing market, by analyzing the role of household, housing, and policy factors on housing purchase intention under the consideration on the difference in priority order of housing supply. Employing the 2014 Newlyweds National Housing Panel Survey, we found that householder age(+), household members(+), child-plan(+), relocation(+), metropolitan residents(-), housing application(+), public housing intention(+) are significantly associated with housing purchase intention at the 0.05 level. Notably, there is the difference in significant factors between the first- and second order household. More specifically, child-care policy was negatively associated with purchase intention among first-order samples, but such relationship was not found among second-order samples. Therefore, given a distinct difference on policy preference by marriage duration of the newlyweds, a customized strategy for housing supply related to child-care supportive policy is required to improve the effectiveness of the previous housing supply policy for the newlyweds.
