Disaster is when, where, and how uncertainties, which might occur. Thus, for disaster response and management at the national and local governments have been made. Korea has established the Disaster and Safety Management Basic Act. Disaster Management has been made at the national level which is to prevent disasters and countries in order to protect citizens from harm and dangerous. Korean Disaster management system is well equipped with advanced countries. The Organization of national and local government are well-maintained substantially for the disaster activities and step-by-step manuals activities. Despite that uncertainty, due to the nature of the disaster, while infrequent, causing large-scale tragedy. Minimize the damage of the disaster as a disaster management efforts are needed. Normally a real disaster, a disaster situation, efforts are to be utilized efficiently, the effectiveness of the system will appear. But while the number of large-scale disasters, including the sinking of Sewol this time for the government and local governments see the response process, the system did not work and the manual existed in the cabinet. There was no Prevention and preparation activities, there was no integrated organization for the response management with expertise in the professional staff. Whenever a large disaster raised repeatedly as a problem, but there was a substantial change in formal but no improvement. It will not reduce the damage if the disaster management is not prepared for a revolutionary turning point.

본 논문은 중소 도시하천을 위한 수해관리시스템 개발에 관한 것이다. 일반적으로 도시하천은 집중호우 발생 시 수위가 급격히 상승하는 특성이 있으므로 하천 재난관리 측면에 있어서 특별한 주의가 필요하다. 따라서 이와 같은 하천의 경우에는 강우와 유출 관계식으로부터 수립된 수문학적 모형을 사용하여 홍수 발생 여부를 예측하는 것 보다는 하천 수위의 실시간 변동 상황을 즉시 감지하고 위험상황 발생 시 이를 신속히 전파하는 것이 재난관리 측면에 있어 더욱 유리할 수 있다. 본 연구에서는 이를 위하여 실시간 센서 데이터를 보다 효율적으로 처리할 수 있는 복합 이벤트 처리기법을 사용하여 수해관리시스템을 개발하였다. 또한, 외부의 재난관리시스템과 정보를 공유하며 연동을 원활히 수행할 수 있으며 경보를 다수의 사용자에게 효과적으로 전파할 수 있는 이벤트 주도적 아키텍처를 적용하였다. 본 연구를 통해서 최근 실시간 데이터 처리기법으로 주목을 받고 있는 복합 이벤트 처리기법이 수해관리에 효과적임을 알 수 있었으며 타 분야의 재난관리에도 널리 적용될 수 있는 것으로 파악되었다.

This study examines the definitions and the scopes of risk, crisis, and disaster management in narrow and wide sense. Generally, the meanings and the scopes of these terms have been used in a very confused manner, and that is the main reason of the difficulty of interdisciplinary approach to disaster related study. In a practical manner, these terms needs to be defined more correctly, for the effective communications among various fields of academic and professional disciplines. This study tries to divide the meanings and the scopes of risk management, disaster management, and crisis management in narrow and wide sense, to define them in a more elaborate manner. Though these three terms can be distinguished in narrow sense, they have almost same meanings when we use them in wide sense.

To minimize the damage from disasters, various aspects of prevention, preparation, and response, etc. are being managed. Even though prevention and preparation are well conducted, irresistible calamities such as natural disasters may cause unexpected damage. Therefore, a system that can share the identical disaster information based on prompt disaster management and prediction must be developed and constructed for integrated disaster management. Especially, for a prompt disaster response, the same information needs to be shared between the related organization and the disaster prevention personnel such as on-site officials. Recent disaster management systems use high-capacity geographic information or other various factors for accurate disaster predictions. In case of using a recently constructed or researched 3D GIS, the system may not be used in some cases due to conflicts with hardware, etc. Thus, even though response information is secured using prediction simulation in advance, it is essentially difficult in some cases to share the common information when the system cannot be utilized or the extension of the corresponding data cannot be read. Therefore, this study aims to construct a system for dealing with disasters that shares the same prompt and accurate information in compliance with common data formats. The system is expected to reduce the existing disaster response time and minimize human and physical damage by assisting decision making through prompt responses.

Recently, damage scale of human-induced disaster is sharply increased but its occurrences and damages are so uncertain that it is hard to construct a resonable response & mitigation plan for infrastructures. Therefore, the needs for a advanced risk management technique based on a probabilistic and stochastic risk evaluation theory is increased. In this study, these evaluation methods were investigated and a advanced disaster risk evaluation method, which is based on the probabilistic or stochastic risk assessment theory and also is a quantitative evaluation technique, was suggested. With this method, the safety changes as the result of fire damage management for recent 40 years was analyzed. And the result was compared with that of Japan. Through the consilience of the traditional risk assessment method and this method, a stochastical estimation technique for the uncertainty of future disaster's damage could support a cost-effective information for a resonable decision making on disaster mitigation.

Recently, due to the rising incidence of disasters in the nation, there has been a growing interest in the relevance and role of science and technology in solving disaster and safety related issues. In addition, the necessities of securing the human rights of all citizens in disaster risk reduction, identifying fields of technology development for effective disaster response, and improving the efficiency of R&D investment for disaster and safety are becoming more important as the different types of disasters and stages of disaster and safety management process have been considered. In this study, we analyzed bipartite or two-mode networks constructed from an expert survey dataset of technology development for disaster and safety management. The results reveal that earthquake and fire are the two disasters affecting an individual and society at large and demonstrate that AI and big data analytics are effective supports in managing disaster and safety. We believe that such a network analytic approach can be used to explore some important implications exist for the national science and technology effort and successful disaster and safety management practices in Korea.

위성영상정보는 센서의 종류, 취득, 분석, 재난과 위성영상 특성 매칭 등의 제약으로 재난 상황에서 제한적으로 사용되었다. 일반적으로 인공위성의 종류는 탑재한 센서의 정보제공 능력 범위에 따라 분류 가능하며 이에 따라 대상 범위가 결정된다. 본 연구에서는 재난의 예측, 탐지, 사후처리를 위한 위성자료의 취득과 활용을 위해 다양한 위성과 탑재된 센서의 궤도, 공간 해상도, 파장대 등의 특성에 대하여 분석하고 재난유형별로 최적 위성영상을 선정하였다. 행정안전부에서는 재난과 재해의 유형을 자연재난(10종)과 사회재난(27종)으로 분류하였다. 위성영상 활용이 가능한 재난 유형은 가시적으로 확인이 가능한 자연재난에 해당하며 그 중 태풍, 홍수, 가뭄, 산불 등 총 4종의 재난유형별로 가용한 최적의 위성영상을 분석하였다. 재난관측에 사용 가능한 대표적인 탑재체의 종류는 극궤도 지구관측 위성에서 광학과 SAR로 구분할 수 있다. 각 기본 특성에 따라 제공되는 정보의 종류가 분류되며 광학 센서는 태양복사 및 지구복사에너지 파장 영역 중 가시광선-근적외선-단파적외선-열적외선 파장대 영역의 분광 정보를 제공할 수 있는 다중 밴드들로 구성된다. 지표의 특정 대상이나 물질을 탐지하고 변화를 감지·분석하는데 유용하여 홍수, 태풍, 지진 등 자연 및 사회 재난·재해 관측에 유용하게 이용된다. SAR 센서는 장파장의 전자기파를 방출한 후 돌아오는 신호를 활용하여 대상에 대한 정보를 획득한다. 대기의 효과 및 요소를 투과하는 주파수 대역별 장파장 밴드 정보를 활용하여 고해상도의 대상 표면, 위치, 형태 등의 정보를 측량 및 관측하므로 중·광역 지역에 제약 없이 영상정보를 획득할 수 있어 산사태, 홍수, 지진, 등의 재난 모니터링에 유용하다. 이러한 다종 위성별 센서들의 특징(공간 해상도, 파장대별 밴드 특성, 관측폭, 재방문 주기 등)들을 분석하여 재난유형별로 가용한 무료/상용 지구관측위성을 분류한 결과 태풍에는 광역관측, 정지궤도 위성, 홍수에는 광학 및 SAR 고해상도 위성, 가뭄은 광역관측, 다분광 광학 위성 그리고 산불에는 정지궤도, 광학, SAR 위성이 적합함을 알 수 있다.

High-resolution satellites capable of observing the Earth periodically enhance applicability of remote sensing in the field of national disaster management from national disaster pre-monitoring to rapid recovery planning. The National Disaster Management Research Institute (NDMI) has been developed various satellite-based disaster management technologies and applied to disaster site operations related to typhoons and storms, droughts, heavy snowfall, ground displacement, heat wave, and heavy rainfall. Although the limitation of timely imaging of satellite is a challenging issue in emergent disaster situation, it can be solved through international cooperation to cope with global disasters led by domestic and international space development agencies and disaster organizations. This article of special issue deals with the scientific disaster management technologies using remote sensing and advanced equipments of NDMI in order to detect and monitor national disasters occurred by global abnormal climate change around the Korean Peninsula: satellite-based disaster monitoring technologies which can detect and monitor disaster in early stage and advanced investigation equipments which can collect high-quality geo-information data at disaster site.
