All means of communication using base stations are interrupted if the scorched earth environment happens because of a disaster. In order to use the systems of the public protection and disaster relief standards, users have to use the special equipments and need the expertise of the operation. Also, it needs the enormous investment for building an infrastructure. The systems is inadequate for the quick and efficient disaster communication, and the people can be in the chaos before the national resources are committed. For solving this problem, this paper presents the design of the mobile application that general people can use immediately, and implements the android phone's application for the proof of concept.

With the emergence of a climate crisis, climate disasters have recently been clearly felt in Korea. In particular, the typhoon 'Hinnamno' in the summer of 2022 made many people feel a sense of crisis with its formidable power. In this situation, children are likely to suffer great damage even in small crises due to their lack of experience and ability to cope with disaster situations. In this paper, we introduce a disaster response learning application that supports children's disaster response training. Designed based on research results on situational learning theory and child disaster safety education, this system produces various episodes and trains them to encounter disaster situations. Children can participate in the episode by choosing options during the episode, which is reflected in the picture diary after the episode is completed. By providing information naturally in the picture diary, children can access how to cope with disaster situations. Through this system, children are expected to develop their judgment in disaster situations that they can encounter and have the ability to secure basic safety outside of adult help.

In this paper, we propose an efficient dynamic workload balancing strategy which improves the performance of high-performance computing system. The key idea of this dynamic workload balancing strategy is to minimize execution time of each job and to maximize the system throughput by effectively using system resource such as CPU, memory. Also, this strategy dynamically allocates job by considering demanded memory size of executing job and workload status of each node. If an overload node occurs due to allocated job, the proposed scheme migrates job, executing in overload nodes, to another free nodes and reduces the waiting time and execution time of job by balancing workload of each node. Through simulation, we show that the proposed dynamic workload balancing strategy based on CPU, memory improves the performance of high-performance computing system compared to previous strategies.

본 연구는 공중보건 비상사태 발생 시 시민들의 위기의식과 신뢰 간의 관계를 살펴보았다. 위기의 영향은 개인, 사회, 국가에 따라 다르다. 정부의 위기관리는 특히 '공공성'이라는 측면에서 비정부기구와 매우 다른 것이 국민의 책임의식을 해소하기 위한 관료제를 수반하기 때문이다. 전염병 확산 단계에서 사람들은 부정적인 감정에 쉽게 빠지게 되며, 중대사고 발생 후 대중의 부정적인 감정을 줄이는 것은 중대사고로 인한 조직의 피해를 효과적으로 줄일 수 있다. 코로나19 팬데믹 상황에서 시민들의 위기의식이 신뢰에 미치는 영향을 기반으로 공중보건 위기상황의 관리를 최적화하고 시민들의 정신건강을 증진 시킬 수 있는 방안에 대한 지침을 제공해야 한다고 판단 된다.

대량의 인명 피해가 발생하는 도심 내 급속 확산형 재난 상황이 전 세계적으로 발생함에 따라, 재난 대응을 위한 응급 운송 및 시뮬레이션 연구에 대한 관심이 증가하고 있다. 본 연구에서는 최근 다양한 방법으로 연구되고 있는 재난 대응 응급 운송 및 시뮬레이션 연구의 동향을 구조적인 내용 분석 기법을 이용하여 정리하였다. 우선, 재난 발생 전/후에 발생하는 응급 운송에 관한 문제들을 분류하고 문제의 특징을 분석하였다. 그리고 응급 자원의 최적할당 및 피해 지역 사람들의 효과적인 이송에 관한 의사 결정을 지원하기 위한 시뮬레이션 연구를 정리하였다. 최종적으로, 이러한 구조적 내용 분석을 바탕으로 자율 적응형 재난 대응 체계 구축을 위한 미래의 연구방향을 제시하였다.

본 논문의 목적은 "재난"에 대해 정의하는 것이다. 이를 위해 우리나라에서 사용해 왔던 정의에 대해 알아보았다. 다음으로 국제 기구에서 제안된 정의를 분석하였다. 재난을 정의하기 위해 필수적인 위기모델을 설명한 후 재난을 정의하였다. 최근 전세계적인 재난과 이에 대처하기 위한 국제적인 노력이 많이 이루어지고 있다. 이러한 상황에서 전세계적으로 통일된 용어의 사용이 매우 중요할 것이다.

재난안전은 아무리 강조해도 지나치지 않고 재난 발생은 그 끝이 없습니다. 그래서 항상 재난에 대비하고 관련 규칙을 철저히 준수해야 합니다. 설마 하는 방심이 누적되어 불시에 대형 참사가 발생하며 이러한 재난이 발생하고 난 후에 책임공방과 과실을 따져봐야 이미 발생한 재난의 시련은 이미 돌이킬 수 없습니다. 그동안 발생한 대형 참사를 통하여 배운 교훈은 일사불란한 통합지휘체계에 의한 재난 관리 및 재난 대응 시스템이 절실히 필요하다는 사실입니다. 그러나 아직까지도 한반도의 산간오지 및 도서 지역을 커버하는 음성 그룹통신 기반의 재난안전통신망이 제대로 구축되어 있지 않으며, 이러한 상황에서 정부는 음성과 영상 그룹통신이 가능한 멀티미디어 방식의 PSLTE 구축을 3년 내에 전국을 커버하는 재난안전통신망으로 구축할 계획을 발표하였지만 이에 대한 기술표준과 상용화 장비 등이 구현되어 있지 않아 3년 내 전국망 구축이 쉽지 않다는 전망이 나오고 있습니다. 객관적 입장에서 PS-LTE 재난망의 개념, 표준화 방향과 추진 일정, 재난안전통신망의 문제점, 시장선점을 위한 원천기술, 국내시장 활성화 방안 그리고 기타 재난 경보방송 서비스에 대하여 살펴보겠습니다. 이번만큼은 어떠한 재난이 발생하더라도 신속하고 정확하게 그리고 일사불란하게 국가재난에 대응하는 현존 최고의 재난안전통신망 구축이 완벽하게 이루어지기를 간절히 바랍니다.

This study investigated a total of 22 types (15 types of natural disasters and seven types of social disasters) of disaster and safety data based on the National Daily Situation Report, Disaster Yearbook and annual Disaster Annals issued by the Ministry of Public Administration and Security. Disaster safety data were collected from the daily situation report of MOIS (Ministry of the Interior and Safety). The number of total data cases were 1,760, of which 656 were natural disasters and 1,104 were social disasters. The disasters were then patternized according to their characteristics. The patterning was conducted to set up the disaster and safety data system designed to keep disaster situations under prompt and effective management. The study analyzed the data associated with the activities in the response and recovery stages according to the disaster type. Furthermore, based on the management activities performed with the flow of time following a disaster, this study classified and proposed disaster and safety data patterns to achieve effective disaster management work by analyzing the characteristics of a disaster and safety data and disaster and safety management procedures. Disasters of high similarity were classified by merging and deleting them. This was done to consider the scalability and mutual linkage so that it can be used in the establishment of national statistical data, such as the disaster annual report and disaster annuity.

Disaster management in Korea so far was centered on recovery efforts rather than prior mitigations. Besides, there were no systematic attempts to assemble appropriate information for even for the past disasters. In this reason, the nation has been repeatedly suffered from similar disasters. To prevent and minimize damages from disasters, it is necessary to build an information system that can gather and organize proper information and that can analyze and visualize spatial patterns of past disasters. This research aims at proposing policy measures to foster a GIS based urban disaster management system. To do so, the paper firstly takes a close look at the FGIS in the City of Taegu as an example. Then it examines the effects of GIS based urban disaster management system and suggests future directions to promote it.

In this study, we developed the system that can collect and store environmental disaster data into the database and use it for environmental disaster management by converting structured and unstructured documents such as images into electronic documents. In the 4th Industrial Revolution, various intelligent technologies have been developed in many fields. Environmental disaster information is one of important elements of disaster cycle. Environment disaster information management refers to the act of managing and processing electronic data about disaster cycle. However, these information are mainly managed in the structured and unstructured form of reports. It is necessary to manage unstructured data for disaster information. In this paper, the intelligent generation approach is used to convert handout into electronic documents. Following that, the converted disaster data is organized into the disaster code system as disaster information. Those data are stored into the disaster database system. These converted structured data is managed in a standardized disaster information form connected with the disaster code system. The disaster code system is covered that the structured information is stored and retrieve on entire disaster cycle. The expected effect of this research will be able to apply it to smart environmental disaster management and decision making by combining artificial intelligence technologies and historical big data.
