  • In restroom on high-rise building, exhaust system comprising the blower and duct is installed to discharge the odor and the water is suppled. Thus the restroom with fire and flame protection system may be used as refuge area in a fire situation. The study presents the smoke-proof system which operates such that the exhaust system to discharge the odor is converted to air supply system and appropriate pressure difference between the restroom and the accommodation is maintained. Also real-scale test facilities of smoke-proof system for refuge space using a restroom are installed on 5-story smoke control test building and experiments for evaluating the operational performance of smoke-proof system are carried out.

  • This study chiefly aims to find out the efficient ways of designing community facility convertible to refuge in case of emergency. In order to reach this goal, this study analyzed (1) definition of terminologies regarding disaster and refuge space, (2)present situation of regarding acts and standards, (3)function and spatial specialties of existing community facilities. Besides, in order to clarify the efficient design methods of 'function-convertible-type' community facility, this study executes archival research on (1)spatial requirements, (2)methods of designing futuristic community facility. When making design directives of community facilities, it is important to consider (1)vertical integration of rescue related function, (2)spatial division and architectural installation concerning privacy, (3)proper layout of locker room, shower room, toilet, etc. (4)appropriate size of unit space. It is desirable to execute the refuge function with minimum psychological anxiety in case of disaster through design guideline for 'function-convertible-type' community facility.

  • The study aims at analyzing an underground station refuge model using EXODUS, one of the refuge simulation programs. The model for simulation is the Daegu Subway (Joongang-ro station). The details of the accident are referred to as the simulation condition the refuge time of traveling from the $3^{rd}$ basement platform to the $1^{st}$ basement is mainly calculated, with passengers numbering 1,000 including 329 at car 1079, 320 at car 1080, and 360 who are not on board. Reference data is used to set up the position of passengers. CFAST fire simulator is also used, and a fast curve among the $t^2$ growth curves, selected as fire growth scenario. The zone is divided into a total of 24 including 18 at the $3^{rd}$ basement platform and 6 at the $2^{nd}$ basement the $1^{st}$ basement is excluded in the fire simulation, however.

  • 본 논문에서는 1) 지금까지 이루어진 광장선호연구를 토대로 광장 설계시 이용될 수 있는 12가지 설계지침을 제시하며, 2) 광장선호를 진화 이론의 틀에서 분석한 사례연구를 소개하고 있다. 12가지 광장설계지침은 1970년부터 지금까지 이루어진 광장형태연구들로부터 제시되었으며, 광장 의 위치, 규모, 시각적 특질, 활동, 미기후, 경계설계, 부공간설계, 동선설계, 식재설계, 휴식공간설계, 음식, 조형물설계 등에 관련한 고려사항을 포함한 다. 광장선호를 진화이론에서 분석한 사례연구는 Appleton의 조망과 은신 이론(prospect and refuge theory)을 분석의 틀로 이용하며, 3개 광장에서 의 이용행태 관찰을 바탕으로 한다. 구체적으로 각 광장의 앉는 장소 (sitting area)가 가지고 있는 조망(prospect) 특성과 은신(refuge)특성을 분석하고 이러한 특성들이 사람들의 선택선호도(앉는 장소로서의)와 관련 성이 있는가를 살펴보고 있다. 연구결과를 보면 광장의 성격이 완전히 공 공적(public)일 경우만이 전반적인 선호행태가 조망(prospect)과 은신 (refuge) 특질과 관련되고 반공공적(semi-public)이나 사적(private)일 경우 에는 Appleton의 이론으로 선호행태 설명이 불가능함을 알 수 있다.

  • In the background of rapid urbanization and frequent earthquakes, earthquake disaster prevention planning has become an important topic of current research. Universities are irreplaceable disaster shelter, as they are public institutions with a lot of open space. This article puts forward the concept of "disaster prevention campus". With the refuge behavioral and psychological characteristics of people in the campus when the earthquake happens, it integrated uses GIS spatial analysis technique, takes Shandong Agricultural University as an example, and studies the spatial pattern of earthquake disaster prevention planning in campus from five aspects. The aspects include building distribution, population distribution, analysis of service radius, infrastructure configuration and choice of the optimal refuge path. On the basis of researches above, reform proposals and specific strategies are put forward to build the safe and harmonious disaster prevention campus.

  • In this paper we have considered a nonautonomous predator-prey model with discrete time delay due to gestation, in which there are two prey habitats linked by isotropic migration. One prey habitat contains a predator and the other (a refuge) does not. Here, we have established some sufficient conditions on the permanence of the system by using in-equality analytical technique. By Lyapunov functional method, we have also obtained some sufficient conditions for global asymptotic stability of this model. We have observed that the per capita migration rate among two prey habitats and the time delay has no effect on the permanence of the system but it has an effect on the global asymptotic stability of this model. The aim of the analysis of this model is to identify the parameters of interest for further study, with a view to informing and assisting policy-maker in targeting prevention and treatment resources for maximum effectiveness.

  • It is necessary to build countermeasure for the reduction of flood damage, such as the analysis of shelter activities of local residents and the publishment of flood informations. The control factors for mental refuge activity by the questionnaire survey were classified and estimated into two categories: internal and external ones. Furthermore, the optimal time for refuse activities related to flood risk was derived by hydraulic simulation. The shelter activities considering inundation depth will serve citizen's consensus by exercise, it would aid to support the activities to minimize flood victims.

  • The purpose of this study is to find Healing elements in the late work of Frank Lloyd Wright. Healing elements are mainly composed of physical, social and psychological functions, which are clearly reflected in holistic attitude and intuition in his Organic theory of Architecture. Late works of Wright since 1935 show particularly shapes of triangle and circle creating the emotional images associated with Hope and Infinity. His image-oriented design attitude is thought to be strongly related to the pursuit of Utopian ideal which means peaceful condition. He regarded it as the consequence of integrity and control, which could be thought as condition of Healing environment. Refuge and Prospect can be complementary elements of spatial expression representing peaceful and dynamic condition of the Nature itself. Five works selected in this case study have unique design ideas related to the function and image of Healing environment interpreted by the criteria of Refuge and Prospect.

  • A huge marine accident causes a loss of valuable lives, property and the serious marine environment pollution. IMO adopted resolution A.949(23) to provide Places of Refuge(PoR) to 'Ship in need of assistance', which is to minimize the secondary environmental pollution caused by marine accidents. If the level of risk exceeds a certain range, it is necessary to be designated as Places of Refuge(PoR) after evaluation of potential risk, which is based on the database of several marine environmental factors. Also, it is necessary to develop skills about quantification/standardization of vessel traffic safety, complexity and risk. Because there is the close relation between the problem of designating Places of Refuge(PoR) and the policy of nation for protecting the natural environment of coastal state, it is important to prepare related legislation. In this paper, introduction of Places of Refuge(PoR) in domestic areas have been suggested based on the analysis of several foreign designating cases.
