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.
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

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.
AHP 분석을 활용한 그린 스마트 미래학교 계획요소의 상대적 중요도 산정

This study aims to identify the planning elements of green smart schools and evaluate their relative importance. Initially, a brainstorming session was held with select professional groups specializing in architectural design and educational administration to establish the hierarchy of planning elements. Subsequently, utilizing the AHP method, the relative importance of these planning elements was analyzed based on expert surveys from school facility design practitioners. The results indicated that green schools (0.331) ranked highest in weight at the primary level, followed by mixed-use schools (0.310), smart class (0.207), and space innovation (0.152). In terms of overall composite weight, green energy (0.092), energy control systems (0.091), lifelong learning spaces (0.086), passive architecture (0.069), support from the local community (0.061), and CPTED of facilities (0.061) emerged as vital considerations. These findings suggest that planning guidelines for green smart schools should prioritize energy-efficient facilities and foster connections between school facilities and local communities.
