This study aims to propose a hypothetical urban neighborhood, HanGyo-dong, which is a model for understanding the relationship between the neighborhood change and educational facilities. Three issue layers of the model derived from preceding case studies are: establishment, relocation and redevelopment of educational facilities; formation and redevelopment of adjacent residential areas; and growth of neighborhood commercial cores. The neighborhood changes observed through HanGyo-dong include (1) the formation of educational base and commercial activities along the stream, (2) the growth of student and intellectual community and the installment of public transportation nodes, and (3) the relocation of schools and hospitals followed by a series of redevelopments of single family house into multi-family housing of low-rise residence and high rise apartment complex. The findings call for the collaborative practice of educational administration and neighborhood planning regarding how educational facilities, which were the tool for urban expansion policy, will contribute to the development of the neighborhood's identity as a localized hub.

The purpose of this study was to empirically analyze the effects of physical environment change on the Crime Prevention Through Environmental Design (CPTED) project implemented in Gamcheon 2 Dong on the fear of crime, neighborhood satisfaction, and neighborhood attachment in the poor. In this study, the data collected through field surveys and questionnaires were analyzed using a structural equation model, specifically the SPSS AMOS 25 program. From the results of the analysis, it was found that the neighborhood satisfaction was enhanced by the improvement in the walking environment and the reduction in the neighborhood disorder level of the target area through the installation of major CPTED facilities. The results of the statistical analysis show that the reduction in the neighborhood disorder due to the CPTED project enhanced the neighborhood satisfaction and the level of neighborhood attachment in the local residents. In addition, the changes in the walking environment caused by the CPTED project had a positive effect on the neighborhood satisfaction, and as the degree of neighborhood disorder decreased, the neighborhood satisfaction increased and the local people's attachment level increased.

The purpose of this study is to develop neighborhood assessment tools from the perspective of women in order to evaluate neighborhood environments and suggest better policies and planning practices for women-friendly neighborhood environments. To do so, we analyze correlations between women's quality of life and the neighborhood environment. Specifically, we gave female participants a mapping survey, interview, and questionnaire to collect data targeting women living in Onyang 2-dong and 5-dong in Asan city. First, we developed a neighborhood assessment tool derived from an extensive literature review and particular case studies. The mapping and interview surveys indicated that specific aspects neighborhood life needed to be improved in a similar area. In particular, women complained about Onyangoncheon station, a commercial area, and detached house area. Second, analysis of the neighborhood environmental factors affecting women's neighborhood satisfaction, crime safety, traffic and walking environment, accessibility of living facilities, green and public spaces and childcare environment were statistically significant. Of these, the inclusion of green and public spaces was the most influential factor. Third, the neighborhood environmental factors affecting women's neighborhood attachment, crime safety, traffic and walking environment, accessibility of living facilities, green and public spaces and childcare environment were statistically significant. Of these, accessibility of living facilities appeared to be the most influential factor. Fourth, the neighborhood environmental factors affecting women's housing mobility decisions, crime safety, traffic and walking environment, accessibility of living facilities, green and public spaces and childcare environment were statistically significant. Of these, childcare environment was the most influential factor.

It is not easy to provide sufficient lead time for flood forecast in urban and small mountain basins using on-ground rain gauges, because the time concentration in those basins is too short. In urban and small mountain basins with a short lag-time between precipitation and following flood events, it is more important to secure forecast lead times by predicting rainfall amounts. The Han River Flood Control Office (HRFCO) in South Korea produces short-term rainfall forecasts using the Mcgill Algorithm for Precipitation-nowcast by Lagrangian Extrapolation (MAPLE) algorithm that converts radar reflectance of rainfall events. The Flash Flood Research Center (FFRC) in the Korea Institute of Civil Engineering and Building Technology (KICT) installed a flash flood forecasting system using the short-term rainfall forecast data produced by the HRFCO and has provided flash flood information in a local lvel with 1-hour lead time since 2019. In this study, we addressed the flash flood forecasting system based on the radar rainfall and the assessed the accuracy of the forecasting system for the recorded flood events occurred in 2019. A total of 31 flood disaster cases were used to evaluate the accuracy and the forecast accuracy was 90.3% based on the probability of detection.

Recently, child safety map making education has attracted attention as a way to reduce crimes against children. In Korea, the Ministry of Gender Equality and Family organized a child safety map making education program in 2011. The program's manual was revised in 2013 and the Ministry implemented it as a project to promote the rights of women and children. Child safety map making education aims to raise a child's understanding of their neighborhood, to have voluntary control and normal consciousness as a local inhabitant, to be aware of wrong behavior and crime, and to be part of creating a safe urban environment. However, when compared to educational programs in other major developed countries, the child safety map making education program in Korea currently does not improve a child's awareness of their surroundings. In this workshop study, we proposed and ran a new program to improve children's awareness of their environment based on the active participation of children in the existing safety map educational program. The workshop was held for 4 weeks for 48 students from 5th and 6th grade at Osan Daeho Elementary School. We analyzed this new program's effects with the following results. First, an analysis of the effects of the program on children's recognition of safe and dangerous spaces revealed that their understanding of these spaces increased by 30.4% after the workshop. The safety-related factor in the mind map key concept increased from 0.94 to 4.94, indicating that the children's perception of neighborhood risk and safety factors improved. Second, the analysis of the effects of the program on the children's coping ability in dangerous situations showed that their understanding of how to deal with dangerous situations increased by 11.3%. The children's understanding of facilities they could ask for help, such as police boxes and child safety guard houses, improved by 17.9%. Third, analysis of the effects of child safety map making education on children's understanding of their neighborhood, their perception of responsibility in the neighborhood, and their neighborhood attachment showed that these levels of children's understanding of the neighborhood improved by 6.0% after the workshop.

As the aging society is globally increasing, the guide for the aged-friendly city is suggested by WHO and many cities are preparing to meet with it. The base of this guide for an age-friendly city is an active aging. This study examined how degree the neighborhood environment is age-friendly from older persons' standpoints. The data were collected through the interview with old persons who aged more than 65 years, 117 persons in an urban area and 110 ones in a rural area. The age-friendly degree of neighborhood environment was examined from two aspects. One is how close 12 neighborhood facilities were from the elderly's houses. Another one is how degree the elderly were considered in 4 areas: pedestrian road, traffic, the amount of housing for the elderly, and space layouts of their houses. Findings were as follows. First, the elderly related neighborhood facilities in urban area were closer located to old persons' houses than in rural area, except the senior center. Second, in case of the age-friendly degree of their neighborhood environments, the space layout of house was the highest, and then traffic, pedestrian road, and the amount of housing for the elderly, in order. The consideration degree of wheelchair users was the lowest. Third, the age-friendly degree of pedestrian road, traffic, and room layout of house in rural area were higher than in urban area. However, the amount of housing for the elderly in urban area was higher than in rural area.

"사실 국가건축정책위원장 책임을 떠안는 것에 고민을 많이 했습니다. 작금 건축의 본질에 관해 꽤 진지하게 논하는 결정권자들이 많아진 상황에서 직을 맡은 이상 그냥 시간만 보내진 않을 겁니다. 평소 생각한 건축계의 부족한, 불합리한, 불비한 부분을 임기 중 완전히 고치진 못한다 하더라도 시작은 해놓고 끝내려 합니다." 작년 4월 취임한 승효상 대통령소속 국가건축정책위원장이 국내 건축계 현안에 대한 생각과 앞으로의 계획을 설명했다. 그가 걸어온 삶의 궤적에는 건축의 공공성 문화적 가치라는 단어들이 새겨져 있으며, 이는 그가 활동해 온 건축계 여러 운동 모임에서도 살펴볼 수 있다. 지식인으로서 마땅히 지녀야 할 건축사(Architect)의 책무에 관해서는 쓴소리도 서슴지 않았던 그다. 2014년 서울시 '초대 총괄건축가'로 선임돼 서울시의 도시정책과 건축문화, 공공 공간조성 등 도시계획 전반에 대해 역할을 했다면, 이젠 국가 건축정책의 목표와 관계 부처간 건축정책의 심의.조정까지 그 역할범위가 커졌다. 필드의 건축사라면 승효상 국가건축정책위원장에게 기대하는 바가 큰 게 사실이다. 실제 그의 취임 후 정부 내 국건위의 위상은 과거와 달라졌으며, 작년 9월 4일에는 문재인 대통령이 서울 은평구 구산동 도서관마을에서 열린 '대한민국 국민생활 SOC현장 방문, 동네 건축현장을 가다' 행사에 참석해 도서관, 체육관, 경로당 등 '생활 SOC 혁신의지'를 강조해 눈길을 끌었다. 최근 정부세종신청사 설계공모 관련 논란에는 "국토부에 소관 설계공모 규정을 고쳐야 함을 권고했다. 고칠 거다! 안 고치면 안 되게 돼 있다!"며 목소리에 힘을 주어 재차 강조했다. 제5기 대통령소속 국가건축정책위원장으로 선임돼 지난해 4월부터 역할을 해온 승효상 건축사를 종로구 동숭동 (주)종합건축사사무소 이로재(履露齋)에서 만났다.
