With about 75% of the population of Korea criticizing the government's disaster policy and a failure to respond to large-scale emergency like the Sewol ferry sinking means that there is a deep distrust in the government. In order to prevent dreadful disasters such as the Sewol ferry sinking, it is important to secure a prime time with respect to disaster safety. Improving crisis management skills and managerial role of police officers who are in close proximity to the people is necessary for the success of disaster management. With disaster management as one of the most essential missions of the police, as a part of a national crisis management, a step by step strengthening of the disaster safety management system of the police is necessary, as below. First, at the prevention phase, law enforcement officers were not injected into for profit large-scale assemblies or events, but in the future the involvement, injection should be based on the level of potential risk, rather than profitability. In the past and now, the priortiy was the priority was on traffic flow, traffic communication, however, the paradigm of traffic policy should be changed to a safety-centered policy. To prevent large-scale accidents, police investigators should root out improper routines and illegal construction subcontracting. The police (intelligence) should strengthen efforts to collect intelligence under the subject of "safety". Second, with respect to the preparatory phase, on a survey of police officers, the result showed that 72% of police officers responded that safety management was not related to the job descriptions of the police. This, along with other results, shows that the awareness of disaster safety must be adopted by, or rather changed in the police urgently. The training in disaster safety education should be strengthened. A network of experts (private, administrative, and police) in safety management should be established to take advantage of private resources with regard to crisis situtions. Third, with respect to the response phase, for rapid first responses to occur, a unified communication network should be established, and a real-time video information network should be adopted by the police and installed in the police situation room. Fourth, during the recovery phase, recovery teams should be injected, added and operated to minimize secondary damage.

This study shows the result of the security assessment of the nationwide key energy facilities and suggests the ways of improving the security level. According to the study, most of the energy facilities are adequately equipped with physical security factors such as security personnel, security systems, fences, and guard posts, but lack of awareness is pervasive among those concerned, so the security operation is inefficient. In other words, inefficient deployment of security personnel, lack of the fundamental knowledge of the security systems, excessive dependence on surveillance cameras' functions such as Pan/Tilt/Zoom, misplaced cameras, low efficiency of monitoring, and irrelevant security plans. To solve these problems, above all, the authority concerned need to develop professional training programs to secure certified security mangers, and need to standardize security process to ensure consistency and to harness the standardization as a source of self assessment to improve security level.

This study mainly focused on the development of real-time based damage investigation system using web-GIS. The study area was Gangseo-Gu in Busan where frequently has relatively higher magnitude of damages from natural disasters. GIS DB was built to provide geospatial data such as 1:1,000 and 1:5,000 topographic maps and IKONOS high resolution satellite data. The web-GIS system has demonstrated the higher contribution for the better response and recovery against any type of natural disasters through real-time communication and data dissemination among government agencies and personnel. However, further researches need to be made to improve system capabilities. In addition, for more effective system operation and maximizing the benefits of exploiting web-GIS system, linkage with national DB such as NDMS is essential.

Quick and accurate understanding of the situation in a severe accident is essential for conducting the appropriate accident management and response using the accident diagnosis information. This study employed deep learning technology to diagnose severe accidents through the major safety parameters transferred from a nuclear power plant (NPP) to AtomCARE. After selecting the major accident scenarios to consider, a learning database was established for particular scenarios affiliated with major scenarios by performing a large number of severe accident analyses using MAAP5 code. The severe accident diagnosis technology, which classifies detailed accident scenarios using the major safety parameters from NPPs, was developed by training it with the established database . Verification and validation were conducted by blind test and principal component analysis. The technology developed in this study is expected to be extended and applied to all severe accident scenarios and be utilized as a base technology for quick and accurate severe accident diagnosis.

국내에서 자연재난의 대부분을 차지하는 홍수는 매년 반복되어 인명과 재산상의 막대한 손실을 유발하고 있다. 이러한 피해 중 인적피해를 최소화하기 위한 방재계획 및 정책수립이 우선되어야 하지만 적용성 측면에서 미진한 부분이 있는 것이 현실이다. 본 연구는 인적피해 평가를 지원하기 위해 피해실적에 근거한 경험적 인적피해 평가기법을 개발하였다. 또한, 해당기법의 적용성을 평가하기 위해 2017년 청주시 호우피해를 기준으로 적용성 검증을 실시하였다. 인적피해의 경우 인명과 이재민 피해를 동시에 고려하였으며, 인적피해를 위해 기본적으로 노출위험인구와 인적피해 발생확률을 기반으로 하였다. 노출위험인구의 경우 침수구역도와 집계구를 기준으로 계층화된 인구 인벤토리를 이용한 GIS 공간분석 결과로부터 결정된다. 그리고 인적피해 발생확률은 행정안전부의 국가재난관리시스템 내 피해이력, 재해연보 및 한국국토정보공사에서 제공받은 침수흔 적도를 토대로 침수등급과 인구계층을 구분하여 제시하였다. 본 연구를 통해 제시된 보다 효율적이고 정밀한 인적피해 평가 방법이 위험지구 결정, 자연재난 리스크 모델링, 방재사업 대안결정, 예산배분 등의 실무와 학술적 접근에 있어 활발히 활용되길 기대한다.

This study developed a system that can collect, manage, and utilize the travel routes of individuals who tested positive for coronavirus disease 2019 (COVID-19) based on the data standardization and quality management principles and presented the analysis data collected from the existing system. Unlike many other countries in the world, Korea demonstrated a rapid response by conducting epidemiological investigations. Further, the local governments have actively shared the travel routes of individuals who tested positive for COVID-19 to facilitate proactive prevention of the infectious disease per the Infectious Disease Control and Prevention Law. However, currently, there is no standard protocol for the local governments to share the information, thus complicating the process of sharing, managing, and utilizing the collected data. Therefore, this study developed a system that can facilitate sharing of the travel routes of individuals who tested positive for COVID-19 by establishing database construction procedures and using the travel route of COVID-19 patients as per the Disaster & Safety Information Sharing Platform and developing a data processing guideline, a data entry system with default templates, and Open API. Although this sharing system was designed to communicate the travel routes of COVID-19 patients, it can also be utilized in case of other infectious diseases. Therefore, it can be used as a response strategy for future outbreaks of infectious diseases.

홍수 발생 시 제내지에 존재하는 도로 및 상·하수도시설물은 저지대를 중심으로 생성되는 침수지역이 아닌 대부분 집중호우, 태풍으로 인해 발생한 유출량이 지표면 유출로 이어져 지면 경사를 따라 유하하면서 흐름을 방해하거나 노후된 시설물 등에서 피해가 발생한다. 이러한 피해발생 특성을 고려하여 홍수피해액을 추정하기에는 침수면적과 시설물 현황 등을 활용하는 기존의 손실 함수 개발 방법으로는 부족한 부분이 존재하며, 유수 흐름의 주요 인자인 침수심, 유속 등과 같은 수리특성을 고려하여 시설물에 대한 홍수피해액을 추정하는 방안이 필요하다. 본 연구에서는 수리특성을 고려한 시설물의 홍수피해액을 추정하기 위한 손실함수를 개발하고자 국가재난정보관리시스템(NDMS) DB에서 해당 시설물의 상세주소를 이용하여 피해 발생위치와 피해액을 파악하였으며, 2차원 수리해석 모형인 FLO-2D를 활용하여 시설물의 피해위치에서 발생된 수리특성 인자인 침수심과 유속을 분석하였다. 시설물의 단위면적 당 피해액을 종속변수로, 분석된 평균 침수심과 평균 유속을 독립변수로 선정한 후 변수 자료들의 신뢰성과 함수의 설명력을 향상시키기 위하여 이상자료들을 제거한 후 손실함수를 개발하였다. 본 연구에서 개발된 손실함수는 수리특성 인자인 침수심과 유속에 의하여 홍수피해액을 직접적으로 추정하는 방법으로 향후 홍수재해에 대한 사전 재산피해 추정을 통하여 합리적인 선제적 예방조치 등의 홍수재해 예방 활동 등에 활용될 수 있을 것으로 기대한다.

Abnormal weather conditions have lately been occurring frequently due to the rapid economic development and global warming. Natural disasters classified as storm and flood damages such as heavy rain, typhoon, strong wind, high seas and heavy snow arouse large-scale human and material damages. To minimize damages, it is important to estimate the scale of damage before disasters occur. This study is intended to develop a strong wind damage estimation function to prepare for strong wind damage among various storm and flood disasters. The developed function reflects weather factors and regional characteristics based on the strong wind damage history found in the Natural Disaster Yearbook. When the function is applied to a system that collects real-time weather information, it can estimate the scale of damage in a short time. In addition, this function can be used as the grounds for disaster control policies of the national and local governments to minimize damages from strong wind.

Recently, a great number of natural disasters have more frequently happened than the past. The National Emergency Management Agency of Korea has made preparation for the integrated management system of steep slope lands. There is information based on the steep slope inspection sheets and the underground spatial information related to the prevention against steep slope disasters. Nevertheless, building a complete DB System to prevent the hazards and secure the safeties should be urgently dealt with. It is mainly because the information of the National Disaster Management System is restricted to the text-based brief data. Therefore, the purpose of this study is to suggest the method as to building steep slope DB system for disaster prevention and maximizing the availabilities. This study shows the way of building a web-based DB system having its root in the steep slope inspection sheets. The method of establishing the ideal DB system that has liaisons between the Ministry of Land, Infrastructure and Transport and the National Emergency Management Agency is discussed in this study. Furthermore the optimization of DB utilization will assist the various integrated steep slope management systems based on U-IT which are ongoing projects.
