Under the "Act on Safety Control of Small Public Facilities (enacted in 2015)", each local government selects and conducts annual safety inspections for small public facilities. Among small public facilities, small bridges pose high risks and are heavily utilized by local residents, making them challenging to manage due to their large numbers and limited resources. Therefore, there is a need for a rational selection method that considers the management capacity of local governments, as well as the establishment of objective risk evaluation and maintenance planning for small hazardous facilities. In this study, we propose a selection method based on structural and functional classification of small bridges, considering the management capacity of local governments. Additionally, we present quantitative evaluation indicators for ten risk evaluation criteria, aiming to facilitate objective risk evaluation.

The main purpose of this study is to reframe sustainability or sustainable development concept in the field of planning in consideration of climate change and natural hazards. The new concept is expected to provide a theoretical foundation for upcoming hazard mitigation measures addressing climate change. The first and main argument of the new concept is that environmental protection should be inclusive enough to address urban (or community) security from current natural hazards. The second is that the balance between structural and nonstructural mitigation measures is critical to cope more effectively with extreme natural hazards in the era of climate change and also with conflicts driven by three goals of sustainability--environmental protection, economic development, and social justice. The following studies, based on this new concept of sustainablity, are expected (1) to address new participation methods for the conflict resolution, (2) to explore detailed and substantive planning strategies and creative technical and institutional solutions for environmental protection, natural hazard mitigation, and conflict resolution. Two of APFM(the Associated Programme on Flood Management)'s three natural hazard risk criteria, Exposure and Vulnerability, may guide the exploration.

The purpose of this study is to suggest a foundational design direction for seniors, according to paradigm shift in aging society. This paper researched on current state of the aging society through literature study and defined the theoretical concept that set the foundation of the study. Secondly, for building an age-friendly city, relevant studies on seven cities were selected and their regional design guidelines were analyzed. As a result, essential design elements for building the aging-friendly city were defined as safety, recognition, and accessibility. A detailed design guideline that applies the three elements with understanding on seniors is required to construct the environment for a senior-friendly city. Ultimately, the result of this study is expected to be in practical use as a fundamental resource for age-friendly city design.

The paper suggests risk management methodology for alleviating casuality accidents at urban railway stations. Risk management deals with countermeasures for reducing accident probability or consequences to reach at the certain level of risk. First of all, Economic evaluations using cost and benefit for all the alternatives are performed. The alternatives exceeding B/C ratio greater than 1, each alternative is applied in the order of higher B/C ratio. this process is repeated when the level of risk is reduced as low as reasonably practical (ALARP). In order to determine the level of ALARP, Level of Service (LOS) for casuality risk at urban railway stations is proposed. The ALARP level is set to the LOS "C". Finally, a case study is applied to the Jongno 3-ga station, which is a highest risky station among all the stations operated by Seoul Metro and Seoul Metropolitan Rapid Transit Cooperation (SMRT).

도시철도유지보수체계 정보화시스템 연구에서 예방정비시스템 구축을 위해 RCM 연구를 진행하고 있으며, 특히 예방정비에서 RCM은 지난 십 수년간 정비보수(Maintenance) 분야의 관리 기법으로 다른 어느 분야의 관리 기법 보다 한층 탁월한 발전을 하고 있다. 특히, 도시철도분야는 매우 복잡한 시스템으로 유지보수에 대한 신뢰성과 효율성 및 안전성을 가장 먼저 확보하여야 한다. 이를 위해서 본 논문에서는 여러 분야에서 오랜 기간동안 운영한 결과 상당한 유익점이 있다고 증명된 신뢰도 중심 정비 (Reliability Centered Maintenance: RCM)에 대한 소개를 하면서 도시철도 시스템에 대한 적용하고자 한다.

본 연구에서 한 지역의 교통안전성을 분석할 수 있도록 교통안전성 지표가 개발되 었다. 연구방법은 회귀분석, 신경망 이론의 적용을 통한 분석, 설문조사였으며 조사지역은 서울시 강남지역이었다. 조사자료는 1996년 교통사고율과 주요 도로설계변수였다. 회귀분석 의 겨로가 8차로 미만의 도로에서는 정지시거가 교통사고 발생을 잘 설명했고 8차로 이상 의 도로에서는 횡단보도의 수가 적절한 설명변수로 선정되었다. 그러나 교통사고 발생에 대 한 설명력이 0.5에도 미치지 못해 심층분석이 요청되어 신경망 이론의 적용이 이루어졌다. 그 결과 교통사고 발생은 회귀분석 결과처럼 정지시거와 횡단 보도수에 관련이 있는 것으로 나타났으며 더불어 접속부의 시거가 중요하게 부각되었다. 한편 사람들의 교통안전성에 대 한 주관적 인식을 알기 위해 설문조사가 이루어졌으며 그 결과 정지시거 외에도 속도의 중 요성이 제기되었다. 이와 같은 분석결과를 근거로 하여 교통안전성 지표가 개발되었으며 지 표 산출에 필요한 평가방법도 정립되었다.

Studying the operation of urban control plan and control program of urban plan facilities to present development direction of urban plan in the future by performing multi-variate analysis, the research acquired the following conclusion. It is required to institutionally activate the inhabitants' participation by reflecting spontaneous participation and opinion of inhabitants to adminstration so that the effect of business can be maximized in the stage of establishing urban control plan. Furthermore, the participation of role dividing type is necessary to adjust and connect the interest of expert that has experience in practical business of overall urban plan, inhabitant and self-governing body. It is required to reduce the service supplied by government so as to enhance policy of plan-first and development last for facilities with high importance and utility such as road, park and water supply/sewage, etc as well as to seek control program that expands the participation of private sector for administration for which private service is possible.

최근에 각종 SOC사업이 본격화되면서 고속도로망 및 도시교통망 확충이 가속화되어 장대 터널이 급증하고 있을 뿐만 아니라 차량의 급속한 증가로 차량배기가스에 의한 터널내부 환경의 악화가 문제시되고 있다. 특히 도로터널은 반밀폐 공간으로 터널내에서의 사고는 인명피해와 막대한 재산 피해로 이어질 수 있으므로 안전운전을 위한 제반설비 및 대책이 필요하며 안전운행을 위한 가시거리 확보 및 쾌적한 환경에 대한 요구가 대두되고 있다. 따라서 터널에서 이와 같은 요구를 만족하기 위해서 기계환기설비가 투입되고 있으며 이에 대한 최적화 설계에 대한 필요성이 높아지고 있다.(중략)
