This research aims to formulate a mathematical model and develop an algorithm for solving a location problem in emergency medical service vehicle parking. To find an optimal parking location which has the least risk score or risk priority number calculated from severity, occurrence, detection, and distance from parking location for emergency patients, data were collected from Pratoom sub-district Disaster Prevention and Mitigation Center from October 2010 to April 2011. The criteria of risk evaluation were modified from Automotive Industry Action Group's criteria. An adaptive simulated annealing algorithm with multiple cooling schedules called multi-agent simulated quenching (MASQ) is proposed for solving the problem in two schemes of algorithms including dual agent and triple agent quenching. The result showed that the solution obtained from both scheme of MASQ was better than the traditional solution. The best locations obtained from MASQ-dual agent quenching scheme was nodes #5 and #133. The risk score was reduced 61% from 6,022 to 2,371 points.

In generally speaking, the purpose of Environmental Impact Assessment(EIA) is to give the environment its due place in the decision-making process by clearly ealuating the environmental consequence of a proposed activity before action is taken. The introduction of conventional EIA is to be seen as an end product of a very long evolutionary process, starting with rudimentary but evolving pollution control measures for air, water, noise, land and chemicals, each governed by separate, and separately administered pieces of legislation. In EIA process, the measures of status, scoping, proposed mitigation and communication have not been very quantitative in their significancy. Of course, the determinations have uncertainity in the implications for significant impacts. To improve the determination of significant impacts, some more comprehensive methodologies of EIA has been proposed with the concepts of risk analysis in the proposed projects. The concepts of risk analysis has been introduced to the expression of human health impairment due to environmental pollutants since the early 1980's. The risk analysis being meant by the statistical significance of impact has a process quantitatively considering uncertainities and importances of ecological systems and human health as well. The process of risk analysis shows assessment, doseresponse in toxicity, exposure assessment and risk characterization. With the risk assessment, it could be suggested for the proper measurements against their anticipated risk in the EIA. This paper deals the priciples developing process and application of the risk-based analysis in EIA.

The aim of this paper is to show how the paradigm of disaster resilience may help reorienting urban planning policies in order to mitigate various types of risks, thanks to carefully thought action on heritage and conservation practices. Resilience is defined as the "capacity of a social system to proactively adapt to and recover from disturbances that are perceived within the system to fall outside the range of normal and expected disturbances." It relies greatly on risk perception and the memory of catastrophes. States, regions, municipalities, have been giving territorial materiality to collective memory for centuries, but this trend has considerably increased in the second half of the 20th century. This is particularly true regarding the memory of disasters: for example, important traces of catastrophes such as urban ruins have been preserved, because they were supposed to maintain some awareness and hence foster urban resilience - Berlin's Gedachtniskirche is a well-known example of this policy. Yet, in spite of preserved traces of catastrophes and various warnings and heritage policies, there are countless examples of risk mismanagement and urban tragedies. Using resilience as a guiding concept might change the results of these failed risk mitigation policies and irrelevant disaster memory processes. Indeed, the concept of resilience deals with the complexity of temporal and spatial scales, and with partly emotional and qualitative processes, so that this approach fits the issues of urban memory management. Resilience might help underlining the complexity and the subtlety of remembrance messages, and lead to alternative paths better adapted to the diversity of risks, places and actors. However, when it is given territorial materiality, memory is almost always symbolically and politically framed and interpreted; Vale and Campanella had already outlined this political aspect of remembrance and resilience as a discourse. Resilience and the territorialization of memory are not ideologically neutral, but urban risk mitigation may come at that price.

강우는 자연과 인간에게 중요한 자원이다. 적절한 강우는 농작물의 성장과 토지의 온도를 일정하게 유지시켜줌으로써 우리 사회가 안정적으로 유지되도록 하는 매우 중요한 역할을 한다. 그러나 태풍 및 집중호우 등과 같이 특정 지역에 계획강수량보다 더 많이 발생한 집중강우는 시설물 및 인간에게 커다란 피해를 입히기도 한다. 이에 따라 미국, 일본 등 국외 선진국의 수재해 대응기관들은 시설운영자와 재난전문가, 응급대응인력들에게 가이드라인을 제공하기 위해 수재해 EAP(Emergency Action Plan)를 작성 운영하여 시설물을 보호하고 강화하는데 활용하고 있다. 대표적인 예로, 미국의 FEMA와 DHS는 시설물과 인명을 보호하기 위해 댐, 제방 등을 위한 다양한 EAP를 운영하고 있는데, 특히 FEMA는 EAP를 시설물이나 인명에 가해지는 피해나 기능적 충격과 같은 응급상황을 감소시키기 위해 작성하는 공식문서로 규정하고 있으며, 이 EAP를 통해 응급 시에 발생할 수 있는 모든 상황뿐만 아니라 평상시 발생할 수 있는 시설물관리상의 문제까지 대응이 가능하도록 규정하고 있다. 이에 본 연구에서는 미국, 일본 등 국외주요국과 국내에서 사용중인 EAP 관련 규정을 분석하여 국내 상황에 적합한 EAP 체계를 제안하였다. EAP는 예방, 준비, 대응, 복구의 재난단계별로 시설물과 인명을 보호하기 위해 재난전문가들과 시설운영자들이 취해야 할 업무, 응급장비 운용 등의 내용을 담고 있다. 본 연구를 통해 개발된 EAP 프레임워크는 테스트베드 적용을 통해 적정성을 평가받았으며, 국내 홍수재난 위험을 감소시키기 위한 절차와 방법 개선에 기여할 것으로 기대된다.

Warning phase of disaster is a critical period in determining the likely survival of threatened citizens. Elderly requires special attention primarily because they tend to be uncompliant and less likely to cooperate with authorities. But there is much less research on how elderly respond to disaster warnings, while there is a strong consistent empirical literature on older citizen in the recovery periods of disaster. The purpose of this study is to examine coping behavior of elderly when they are at risk of disaster. Data were collected from 130 senior citizens aged over 60 who are residing in Pyungchang and Injae in Kangwon province which had damaged due to heavy rain in 2006. Perry & Lindell(1997)'s index, a series of six categories that represent coping behaviors which progressively approximate the action of evacuating was used : do nothing(1), check environmental cues for evidence of a threat(2), engage in threat-specific property protection(3), engage in protective action for personal safety(4), prepare to evacuate(5), evacuate the areas as instructed in the warning(6). Almost respondents(69.2%) chose the level 6(51.5%) and level 5(17.7%). This proves the elderly are not uncompliant or uncooperative population. Furthermore, this finding emphasizes the importance of public warning in case of disasters. And 13.8% of total respondent checked level 1 for their reaction.

Containment Filtered Vent Systems (CFVSs) have been mainly equipped in nuclear power plants in Europe and Canada for the controlled depressurization of the containment atmosphere under severe accident conditions. This is to keep the containment integrity against overpressure during the course of a severe accident, in which the radioactive gas-steam mixture from the containment is discharged into a system designed to remove the radionuclides. In Korea, a CFVS was first introduced in the Wolsong unit-1 nuclear power plant as a mitigation measure to deal with the threat of over pressurization, following post-Fukushima action items. In this paper, the overall features of a CFVS installation such as risk assessments, an evaluation of the performance requirements, and a determination of the optimal operating strategies are analyzed for the Wolsong unit 1 nuclear power plant using a severe accident analysis computer code, ISAAC.

Background: The current study reports measurements of activity concentrations of radon (²²⁰Rn) and thoron (²²⁰Rn) in dwellings, followed by inhalation dose assessment of the public, and then by the development of regulation and the national radon action plan (NRAP) in Cameroon. Materials and Methods: Radon, thoron, and thoron progeny measurements were carried out from 2014 to 2017 using radon-thoron discriminative detectors (commercially RADUET) in 450 dwellings and thoron progeny monitors in 350 dwellings. From 2019 to 2020, radon track detectors (commercially RADTRAK) were deployed in 1,400 dwellings. It was found that activity concentrations of radon range in 1,850 houses from 10 to 2,620 Bq/㎥ with a geometric mean of 76 Bq/㎥. Results and Discussion: Activity concentrations of thoron range from 20 to 700 Bq/㎥ with a geometric mean of 107 Bq/㎥. Thoron equilibrium factor ranges from 0.01 to 0.6, with an arithmetic mean of 0.09 that is higher than the default value of 0.02 given by UNSCEAR. On average, 49%, 9%, and 2% of all surveyed houses have radon concentrations above 100, 200, and 300 Bq/㎥, respectively. The average contribution of thoron to the inhalation dose due to radon and thoron exposure is about 40%. Thus, thoron cannot be neglected in dose assessment to avoid biased results in radio-epidemiological studies. Only radon was considered in the drafted regulation and in the NRAP adopted in October 2020. Reference levels of 300 Bq/㎥ and 1,000 Bq/㎥ were recommended for dwellings and workplaces. Conclusion: Priority actions for the coming years include the following: radon risk mapping, promotion of a protection policy against radon in buildings, integration of the radon prevention and mitigation into the training of construction specialists, mitigation of dwellings and workplaces with high radon levels, increased public awareness of the health risks associated with radon, and development of programs on the scientific and technical aspects.

In this study, we conducted a pilot study on the multiple spurious operations (MSO) analysis in the fire probabilistic safety assessment (PSA) of domestic nuclear power plant (NPP) to identify the degree of influence of the operator actions used in the MSO mitigation strategies. The MSO scenario of the domestic reference NPP selected for this study is refueling water tank (RWT) drain down event. It could be caused by spurious operations of the containment spray system (CSS) of the reference NPP. The RWT drain down event can be stopped by the main control room (MCR) operator actions for stopping the operation of CSS pump or closing the CSS motor operated valve if the containment spray actuation signal (CSAS) is spuriously actuated. Outside the MCR, it can be stopped by operator actions for closing the CSS manual valves or motor operated valve or stopping the operation of CSS pump. The quantification result of a fire PSA model that takes into account all recovery actions for the RWT drain down event lead to risk reduction by about 95%, compared with quantification result of fire PSA model without considering them. Among the various operator actions, the recovery action for the spurious CSAS operations and the operator action for the manual valve are identified as the most important operator actions. This study quantitatively showed the extent to which the operator actions used as MSO countermeasures have affected the fire PSA quantification results. In addition, we can see the rank of importance among the operator recovery actions in quantitative terms.

쓰나미라 불리는 지진해일은 드물게 일어나는 현상이지만 일어날 경우 대피할 수 있는 시간이 촉박하며, 엄청난 인명, 재산피해를 유발하므로 이에 대한 대비는 매우 중요하다. 쓰나미는 자연재해로 그 피해를 원상 복구하는것은 거의 불가능하나 조기경보체계 등을 통하여 대피함으로서 인명피해를 최소화 할 수 있다. 이러한 자연재해에 대한 피해경감과 재난관리를 위하여 GIS의 지오프로세싱 기능과 분석기능은 유용한 도구가 될 수 있다. 본 연구는 쓰나미의 경우에 있어서 GIS의 지리정보 프로세싱 기능을 이용하여 대피계획 수립에 필요한 관련정보 통합 프로세싱 모형을 구축하고자 하는데 그 목적이 있다. 쓰나미의 경우 주된 대피는 인구를 발생지역으로부터 수평적, 또는 수직적으로 이동시키는 것과 관련이 있으며, 이를 위한 대피와 대응의 과정을 4단계로 구분 하였으며, 각 단계마다 필요한 입력데이터를 정하였다. 최종모형은 이러한 4단계를 통합하여 최종모형으로 제시하였다. 본 연구에서 설정된 모델은 매 단계의 입력데이터를 달리하여 쓰나미 발생이 예상되는 해안도시에 적용할 경우 인구의 대피와 관련한 의사결정에 활용될 수 있다.
