연구방법론 관점의 CPTED 실험연구 동향

서민진,강석진,김고원 한국셉테드학회 2022 한국셉테드학회지 Vol.13 No.3

Experimental research is a method suitable for intentionally creating the environment desired by the researcher and revealing the causal relationship between variables. The characteristics of these experimental studies are being utilized in the CPTED field to overcome the survey's limitations. However, there are few cases of experimental research conducted in domestic CPTED experimental research compared to other fields. And most of the simple experimental designs(pre-experimental design) are performed, so the design is insufficient. In addition, some studies have limitations that are difficult for subsequent researchers to apply because the experimental design and process do not appear in detail. Therefore, this study recognized the necessity of an effective experimental research system, and the concept of experimental research and the experimental design of previous studies were considered. Finally, the experimental design of the previous study was supplemented through the analysis results.

This study examines factors that affect the fear of crime experienced by single-person households living in multi-family housing (general or piloti buildings) that require high levels of crime prevention through environmental design (CPTED). There was a significant correlation between the window size of a low-story house and the fear of violence during the day and at night based on the experiment results. Additionally, it was found that parking in front of buildings was significantly positively related to the fear of crime, including burglary and violence during the day. For crime prevention building criteria related to multi-family housing, the ratio of factors applied to facilities was much higher than architectural factors. In conclusion, architectural standards should be developed to enhance the natural surveillance of windows and staircases, as well as to clarify the territoriality of the first-floor entrance space (parking as well as a pedestrian). 본 연구의 목적은 범죄예방설계(CPTED)의 필요성이 높은 다세대주택(일반/필로티 건물) 1인 가구의 범죄 불안감 영향요인을 규명하는 것이다. 실험 결과, 저층 창문의 크기는 주/야간 폭력 범죄 불안감, 건물 앞 주차는 주간 절도/폭력 범죄 불안감에 유의한 정(+)의 관계가 검증되었다. 다세대주택과 관련된 범죄예방 건축기준은 건축적 요소보다 시설 적용 요소의 비율이 높았다. 이에 따라 1층 진입공간(주차/보행)의 명확한 구분(영역성 강화)과 창문, 계단실의 자연 감시를 높일 건축적 요소에 대한 기준 보완이 필요할 것으로 보인다.

범죄 안전을 위한 서울시 청년 여성 1인 안심주택 연구

서민진,임보영,강석진 대한건축학회 2023 대한건축학회논문집 Vol.39 No.4

본 연구는 청년 여성 1인 가구의 범죄 안전을 위한 시사점을 도출하기 위해서 관련 사업과 범죄예방 건축기준, 안심주택 사례를 고찰하였다. 연구 결과, 범죄예방 건축기준(53.8%)과 서울시 1인 가구 지원제도(41.2%) 모두 공적 공간의 적용 비율이 가장 높았는데, 안심주택 거주민이 요구하는 것은 영역적 경계가 불명확한 반사적/반공적 공간(65.0%)의 건축적 개선임이 확인되었다. 불특정 다수를 대상으로 지원하는 사업의 특성에 따른 한계라 볼 수 있지만, 이와 관련된 범죄예방 건축기준이나 별도의 건축적 지원(요소)의 적용이 필요하다. This study aimed to investigate related projects and safe housing cases and derive implications for the crime safety of Unmarried Single Womenhouseholds. Analysis of the data collected revealed that the crime prevention building criteria and the Seoul single-person household supportsystem had the highest application rates in public spaces, with 53.8% and 41.2%, respectively. However, the study also confirmed that residentsof women's safe housing required architectural improvements for semi-private space (65.0%), rather than public space (35.0%). Furthermore, thestudy found that crime anxiety was particularly high in areas where territorial boundaries were unclear, such as semi-private and semi-publicspaces. The limitations of the project that supports an unspecified number of people may contribute to this phenomenon. In addition, the studyinfers that it is necessary to implement crime prevention building criteria or introduce separate architectural elements related to crime prevention.

통일 필요성 인식에서의 거주지 효과

서민진,김병연,이정민 서울대학교 통일평화연구원 2022 통일과 평화 Vol.14 No.2

This paper analyzes the relations between the perception of an individual on the necessity of the Korean unification and the public opinion among residents in the same city or province where the individual lives. Using data from the Unification Perception Survey, 2007-2021, we find that the former is significantly correlated with the latter, but there is little effect of the public opinion among residents in the neighboring regions on the individual perception on unification. In addition, it is found that the public opinion in the current area becomes weak or insignificant if an individual moves from a city or province to another one before he/she reaches the age of fifteen. We also uncover that the magnitude of the effect of average opinion on unification within a region on the individual perception on the same issue is lower than such effects regarding issues directly related to the South Korean society. Our findings suggest that social opinion of an individual on economic and political issues including support for inter-Korean unification is formed through interactions between people sharing the same living environments. 본 연구는 서울대학교 통일평화연구원의 통일의식조사 자료를 이용하여 통일의 필요성에 대한 거주지의 평균 인식이 개인의 인식에 미친 영향을 추정한다. 추정 결과 개인의 인식은 같은 지역에 거주하는 응답자들의 평균 인식과 유의한 관련이 있는 것으로 나타났다. 반면 거주지 외부 접경지역의 인식과 개인의 인식 간에는 유의한 관련이 없었다. 또한 15세 이전 최장기 거주지와 현재 거주지가 일치하지 않으며 이 두 지역이 서로 다른 광역권일 경우에는 현재 거주지가 통일 필요성 인식에 유의한 영향을 미치지 않았다. 그리고 통일의 필요성에 대한 인식은 한국 사회에 관한 다른 인식 변수보다 거주지 평균인식과의 관련성이 상대적으로 낮았다. 본 연구의 결과는 개인의 통일 필요성 인식과 거주지역의 평균 인식이 관련이 있음을 보였을 뿐 아니라 그 경로 중 하나로 사회적 영향, 즉 자신이 속한 집단의 평균적 행동이나 태도로부터 영향을 받을 가능성을 제시한다.

리뷰 및 리뷰어 속성을 활용한 머신러닝 기반 우수 리뷰어 판별 모델 개발 및 검증 : H&B 시장을 중심으로

서민진,양성병 한국경영정보학회 2023 한국경영정보학회 학술대회논문집 Vol.2023 No.11

최근 기업들이 온·오프라인 통합 리뷰 서비스를 강화하며 온라인 리뷰의 영향력이 높아지고 있는 상황이지만, 이벤트성 리뷰를 작성한 리뷰어 또한 늘어나며 소비자들의 온라인 리뷰에 대한 신뢰가 상실되는 역효과가 발생하고 있다. 따라서, 우수 리뷰어를 판별하는 방법에 대한 분석이 필요함에도 불구하고, 대부분의 선행연구는 우수 리뷰의 판별에만 초점을 맞추고 있다. 이에, 본 연구에서는 H&B시장의 온라인과 오프라인을 모두 고려한 옴니채널(Omni Channel)에서의 리뷰 및 리뷰어 데이터를 수집하여, 빅데이터 분석기법인 감성분석과 머신러닝을 활용하여 신뢰성 있는 리뷰를 작성한 우수 리뷰어를 판별하기 위한 모델을 제안, 개발하고자 한다. 또한, 이 판별모델로 측정한 리뷰어의 순위와 실제 기업에서 제공하는 리뷰어 순위를 비교해보고, 제시된 모델로부터 도출된 우수 리뷰어와 일반 리뷰어의 특성을 통계적인 기법을 활용하여 비교해보고자 한다. 본 연구의 결과를 통해 향후 H&B 시장 옴니채널에서의 리뷰어 관련 학술적 및 실무적 시사점을 제시할 수 있기를 기대한다.

서민진(Seo, Min-Jin),강석진(Kang, Seok-Jin) 대한건축학회 2022 대한건축학회 학술발표대회 논문집 Vol.42 No.1

The purpose of this study is to review the support system of CPTED for housing safety of unmarried single woman households. The research method is a comparative analysis of the support system and application cases according to the CPTED principle. As a result of the study, the ratio of the CPTED principle applied to women"s safe housing was the highest with surveillance (29.0%) and the highest ratio compared to the rest of the cases. Through this, the difference between the CPTED principle applied to public streets (focused on territoriality/legibility) and buildings (focused on surveillance) was confirmed.

This study aims to identify the behavioral factors for improving the pedestrian environment and user satisfaction of commercial streets as the base for the small or medium-sized city. To verify the research model, a survey and observation study (pedestrian density analysis, street activities) were performed targeting the commercial streets in Daean-dong, Jinju-si (Zone A: road-walking and car-sharing, zone B: road-walking only). The results of this survey are as follows: first, zone Bs satisfaction level on the street was higher than zone A. Second, the optional activities had a greater influence on the satisfaction on the street, and this result was consistent with Jan Gehl’s theory. However, the next factors influenced were the necessary activities of Zone A and the social activity of zone B. it seems that such difference depends on the separation of areas for pedestrians and cars. Third, the visit characteristic was most influenced by the social activities. In conclusion, it was confirmed that the street activities were influenced by the satisfaction level on the physical environment and influenced visit characteristics.

In this study, the relationship between theft crimes was analyzed according to the environmental and spatial characteristics of each Land Use Areas. The research was conducted on the A-Dong and B-Dong located at the Old Downtown of J-City. In the residential area of A-dong, the street width, D/H ratio, and the integration value of the Segmented Axial were related to the theft crime. And In the Commercial area of B-dong, The scope of CCTV surveillance and visibility of crime prevention facilities were related to theft crime. However, there were limitations in identifying statistically significant causes of crime, as the areas under study were small and the number of crime data available was small.
