Many severe earthquakes have occurred along the main fault lines in the world. In recent years, there has been a high incidence of small- and large-scale earthquakes in our country. These occurrences of earthquakes have become increasingly serious, owing to a degrading earth environment. An earthquake, in general, causes far more serious damages like disruptions in electricity or gas facilities, and fire disasters from its annexed effects than by its vibrations or the shock itself. In this paper, we present a countermeasure and its necessity in safeguarding against fire disasters in regional heritage villages such as "Asan Oeam," "Jeonju Hanok," and "Andong Hahoe." A more systematic and effective strategy for prevention systems against severe fire disasters is proposed after performing various related investigations and analyses of existing domestic and international systems. We investigated the existing fire security systems and their historical records with the tendency of earthquake occurrences in these three folk villages. In this proposal, we present a strategic approach for safeguarding against fire damages in our regional heritage villages derived from ICT (information communication technology)-based DPD (disaster prevention design), after examining the laws and regulations of fire-prevention strategies in Japan, America, and Europe.

본 연구에서는 1995년부터 2006년까지 12년간 발생한 3,593건의 가스사고사례를 수집하여 데이터베이스를 구축하였으며, 이를 근거로 LPG 기화기사고의 발생건수를 형태 및 원인별로 분석하였다. 분석결과를 살펴보면 사고의 형태로는 파열, 누출, 폭발, 화재 순으로 발생하는 것으로 나타났으며, 기화기 가스사고 중 세부원인을 분석한 결과 가장 많이 발생한 원인으로는 액유출방지장치의 결함에 의한 것으로 분석되었다. 또한 Poisson분석법을 적용하여 향후 5년 이내에 LPG 기화기와 관련된 화재, 폭발, 누출, 파열에 대한 가장 가능성이 높은 발생확률을 예측하였다. 그 결과 사고의 발생횟수가 3번 이하로 발생하는 항목으로는 LPG-Vaporizer-Fire으로 나타났으며, 5번 이하는 LPG-Vaporizer -Products Faults-Check Floater, 10번 이하는 LPG-Vaporizer-Products Faults로 분석되었다. 향후 본 연구에서 구축한 국내사고 Database를 매년 지속적으로 보완 개정을 하면 국내 가스사고 예측에 대한 보다 신뢰성 있는 정보를 제공해 줄 수 있어 효과적인 가스안전관리 대책수립에 기여할 것으로 기대된다.

본 연구의 목적은 공간DB에 구축된 유역 및 관거 데이터로부터 SWMM(Storm Water Management Model) 데이터를 생성하고, 유출 위험관거, 침수지역 및 침수심 등의 분석정보를 GIS기반의 지도에 표출하기 위한 데이터 모델을 설계하는데 있다. 이를 위해 UIS(Urban Information System)와 재해대장, 기상자료 등을 기반으로 침수분석 지역의 속성데이터 생성 방법을 제시하고, ArcSDE 및 Oracle DB를 사용하여 공간데이터를 생성하였다. 또한 유출 위험지역을 지도에 표출하기 위해 ArcGIS ArcObject와 공간DB를 연계하여 프로토타입 시스템을 구축하였다. 본 연구결과는 향후 침수분석 연구에 SWMM을 효율적으로 활용하는데 도움이 될 것으로 기대된다.

단파 복사와 일조시간은 농작물 재배에 중요한 변수들이다. 그러나 국내에서 제공되는 일사 관측 자료는 수평 해상도가 높지 않아 농업 현장에 활용하기 어렵다. 본 연구에서는 지면대기모델링패키지(LAMP)를 이용하여 시간단위 일사 자료를 물리역학적으로 생산하고, 통계적 다운스케일링을 통해 고해상도 일단위 기상기후 DB를 구축하였다. 현재 이 DB는 품질 평가를 거쳐 농업가뭄 재해와 밭작물의 생육 현황을 진단하고 예측하는 '경기도 농업가뭄 예측시스템'의 공식 빅데이터 입력 자료로 활용되고 있다.

Annually, many parts of the Korea have been damaged from the localized heavy rain and/or typhoons which peak between June and September, which result in extensive financial and human loss. Especially, because the most area of Gangwon province is composed of the steep slope mountains, the damages by the debris flow or land-sliding are more frequent and the frequency has been increased. To analyze the characteristics and causes of these debris flow disasters, lots of study are recently being conducted through database of weather, hydrologic, soil etc using a GIS or remote sensing. In this study, we applied GIS method to analyze the risk of the debris flow area. With the statistical analysis and infinite slope stability model(SINMAP), the debris flow risk level of the mountain slope was generated. As a result, the GIS statistical analysis showed high correlation that former model of SINMAP in determining the debris flow risk area.

The fire department has one of the most important role as public resources of response to disasters in the aspect of supply and the adequate distribution of resources of response is essential, but the distribution of the response capability to disaster of fire department does not reflect the regional hazard vulnerability and hazard risks. Researchers performed database process with simple mapping based on the regional fire disaster response capability and the regional hazard vulnerability and hazard risks. The cities and towns are divided to four types each, total eight types and relative threat ratios are extracted from every type. The fire disaster response capability was extracted from number of firemen and fire vehicles in defined region. The distribution of the fire disaster response capability was inadequate and not matching to relative threat especially in small cities and some types of towns. The regional relative threat and resources should be analyzed by more delicate mapping and software development in the future.

Korea Peninsula consists of approximately 70% of mountainous terrain of total area, in addition, annual average rainfall is plentiful, especially during rainy season of summer, and it is often accompanied with typhoon and heavy rain, which results in frequent landslides. Since there are limitations with existing methods to analyze extensive disasters, it is necessary to develop new remote sensing technology using an artificial satellite to study on landslides closely. This paper is written in order to establish the database with map information on various landslides using GIS, furthermore, to analyze precariousness of the areas, which are susceptible to landslide, and risks of potential areas in consideration of heavy rain, based on land-cover classification derived from images from satellite.

China is one of the few countries where natural disaster strike frequently and cause heavy damage. In this paper, we mathematically develop two models to assess fuzzy risk of natural disaster in China. One is to assess the risk based on database of historical disaster effects by using information diffusion method relevant in fuzzy information analysis. In another model, we give an overview over advanced method to calculate the risk of release, exposure and consequence assessent, where information distribution technique is used to calculate basic fuzzy relationships showing historical experience of natural disasters, and fuzzy approximate inference is employed to study loss risk based on these basic relationships. We also present an examples to show how to use the first model. Result show that the model is effective for natural disaster risk assessment.

This study aims to develop the fuzzy risk assessment model of the debris flow to verify the accuracy of risk assessment in order to help related organizations reduce losses caused by landslides. In this study, actual cases of landslides that occurred are utilized as the database. The established models help us assess the occurrence of debris flows using computed indicators, and to verify the model errors. In addition, comparisons are made between the models to determine the best one to use in practical applications. The results prove that the risk assessment model systems are quite suitable for debris flow risk assessment. The reproduction consequences of highlight point discovery are shown in highlight guide coordinating toward discover steady and coordinating component focuses and effectively identified utilizing these two systems, by examining the variety in the distinguished highlights and the element coordinating.
