The purpose of this study is to suggest the strategies of building disaster resistant communities to overcome communities destruction and vulnerability caused by the Hebei Spirit oil spill accident in Taean on December 7th, 2007. For accomplishing the purpose, we drew problems of approach based on context of community, governance strategy, and community-based approach. And based on the results of this analysis, suggestions were made as follows for building disaster resistant communities. First, when Hebei Spirit oil spill accident occurred we have been short of regional study and unreality of regional safety plan. For overcoming this points, we have need of activation of regional study and establishment of regional safety plan based on the bottom-up approach. Second, while the spill has brought a milestone activation of volunteer, we have not still efficient disaster management based on governance. So we have to establish network-governance to cooperate with government-business-private sector for efficient disaster management. Third, we argue that it is important to build social capital such as social networks, social contacts for community-based disaster resistant communities.

Wireless mesh networks for public safety and disaster have been developing in a direction from TETRA(TErrestrial Trunked RAdio) to take advantage of the Public Safety-LTE(Long Term Evolution) technology. In Korea, the Disaster Safety Network Building Project has been promoted in order to unify disaster communication systems among disaster response agencies. In this study, the trends of the network construction for national disaster communication and corresponding representative cases of overseas have been analyzed. Through this process, the disaster communication area in line with the purpose of communications. As a result, the disaster communication can be divided into five distinctive areas: the control, the response, the on-site, the victim and the alarm communications. Based on the re-designed communication areas, quality requirements have also been re-organized in this study. Ultimately the construction method for the Disaster Communication systems without exclusion zone will be presented.

Disaster management system can prepare enough for a social disaster. In addition, it is measures to reduce damage. When, where and how to prepare for a disaster will happen we can not expect an appropriate sense of crisis, disaster response and is the right choice early. In this paper, the next national disaster safety sector effective use SNS will find ways. To do this successfully in the field of international disaster safety use cases and measures are derived that can be applied to our country. As a result, comprehensive and systematic introduction of disaster management system to minimize the damage will contribute effectively to the rapid disaster recovery.

The requirements of disaster prevention have been constantly increasing on highly disaster frequency by Global warming and environmental destruction. The damage occur more highly, especially when it's on the localized change of weather. It requires that we have methods of disaster prevention locally. In this paper, we design and implement a breakwater disaster prevention system integrated wireless sensor technique for the shore breakwater of East Sea that is raised anxiety about an accident occurrence due to stormy weather. The provided disaster prevention system perceive the seriousness of the situation that is chance of that happening by the information of realtime remote situation and a prediction system so that it could be of some help to reduce the damage of disaster and the cost of recovery.

통합공공용 주파수로 분배된LTE(Long Term Evolution) 718~728Mhz(상향) 및 773~783MHz(하향)에서 재난안전 통신망, 철도무선 통신망, 차세대 해상무선 통신망 등과 같은 LTE기반의 공공통신망(Public Network, 이하 공공망)이 상호 공존하여 사용하는 방안에 대하여 연구하였다. 두 개 이상의 복수의 LTE 네트워크가 동일 주파수를 사용하여 서비스하는 경우 통신 커버리지가 겹치는 영역에서의 간섭은 불가피하다. 셀 간 간섭에 의하여Mission Critical한 요구사항이 중요시되는 공공망에서의 품질 열화가 야기되며, 경우에 따라 심각한 상황을 초래할 수 있다. 본고에서는 국내 공공망의 현황을 살펴보고 네트워크 공유방식에 대한 기술 및 표준화 동향, 그리고 해외의 사례를 알아보았다. 국내 통합공공용 주파수에서 동일 주파수를 사용하게 될 공공망 간의 간섭을 최소화 하여 네트워크를 구축 및 연계를 위해서 개별 공공망간의 네트워크를 공유하는 방안을 고려하였다. 국내 공공망의 효율적인 네트워크 연계를 위해서는 개별 공공망의 서비스 특성과 내부 환경을 반영 할 수 있는 연계 방식이 추가적으로 필요하다.

In this study, we conducted a study on the development of Internet of Things-based disaster response system. We researched the method of building the network-based disaster prevention system using a client machine that the sensor network and the keeper. Also, we developed the algorithm for optimal evacuation shelter based on spanning tree algorithm. The system is tested actually in Seoul Gaepo station, and we verified the usability of the system.

The purpose of this study is to examine the social perception of disaster safety education for young children based on Textom big data and to explore the direction of young children's disaster safety education. Researchers collected and analyzed online text data using the keywords 'young children+disaster+safety education' from portal websites from 2014 to 2017. The raw data were then subjected to first and second data refinement process. Based on the frequency analysis results, 50 keywords were selected, and the selected keywords were converted into matrix data for network analysis. The results of the study are: first, the most frequently appeared keyword together with young children's disaster safety education was 'education', followed by 'experience', 'kindergarten', 'prevention', and 'school.' Second, keywords with high centrality in the analysis of centrality also were 'education', 'experience', and 'prevention'. In addition, keywords like 'prevention', 'life', and 'evacuation' appear higher in connection-centricity than frequency ranking, which means that the degree of connection between the words is high. These results suggest that young children need education in during early childhood in order to improve their disaster safety skills, and disaster safety education should be accomplished through 'prevention' and 'experience' in early childhood education institutions.

The Safe Life is an essential subject of education introduced in the 2015 revised curriculum for first and second graders of elementary school to cultivate safety awareness. This study aims to explore the relationship between concepts and concepts that are important in the Safe Life textbook using a keyword network analysis. The results indicate that the areas of life safety, traffic safety, and disaster safety are emphasized in terms of topics in the textbook. The teaching and learning methods for the Safe Life education are mainly based on "experience" and "practice," and the most common teaching materials are card games and sticky stickers. Based on the findings, we suggest maintaining the experience-oriented safety education approach and diversifying the teaching and learning materials and methods to incorporate various safety education areas.
