Currently, disasters occurring in Korea are characterized by unpredictability and complexity. Due to these features, property damage and human casualties are increasing. Since the initial response process of these disasters is directly related to the scale and the spread of damage, optimal decision-making is essential, and information of the site must be obtained through timely applicable sensors. However, it is difficult to make appropriate decisions because indiscriminate information is collected rather than necessary information in the currently operated Disaster and Safety Situation Office. In order to improve the current situation, this study proposed a framework that quickly collects various disaster image information, extracts information required to support decision-making, and utilizes it. To this end, a web-based display system and a smartphone application were proposed. Data were collected close to real time, and various analysis results were shared. Moreover, the capability of supporting decision-making was reviewed based on images of actual disaster sites acquired through CCTV, smartphones, and UAVs. In addition to the reviewed capability, it is expected that effective disaster management can be contributed if institutional mitigation of the acquisition and sharing of disaster-related data can be achieved together.

인구의 고령화로 인한 노인여가복지시설에서 실질적인 생활거점과 복지시설로 역할이 변화하면서 경로당의 이용자가 증가하는 추세이다. 그러나, 다중의 고령층이 장시간 이용하는 시설임에도 불구하고 경로당에서 발생하고 있는 재난 및 안전사고에 관한 기초적인 정보 수집이 전무한 상황이다. 이에, 본 연구는 노인여가복지시설 중 경로당을 중심으로 현장을 직접 방문하여 관련자 인터뷰와 통계자료를 분석하여 재난 및 안전사고 실태를 조사하고자 한다. 또한, 현재 경로당에서 운영하는 프로그램을 조사하고, 노인의 건강하고 안전한 여가생활에 도움을 줄 수 있는 프로그램이 될 수 있도록 활성화 방안을 도출하고자 한다. 본 연구결과가 신(新) 노년 세대를 위한 노인여가복지정책 연구에 기초자료로 활용되길 기대해본다.

In order for preemptive response and prevention against disasters, it is necessary to systematically collect, preserve, manage, and utilize the information resources of records related with disaster safety. Therefore, this study analyzed the types and status of text-based document archives among the records information resources which were published and produced by the disaster safety-related institutions via online. Detail types analysis of disasters in document archives also was conducted. Based on filed interviews, the actual users' requirements for the disaster safety information archives are converged. The ultimate goal of this study is to establish a basis for building of disaster safety information archives by deriving improved management strategies of disaster safety records resources.

지구온난화로 재난 재해가 날로 증가 되고 있으며, 그 규모도 대형화 되고 있는 추세이다. 재난 재해의 원인으로서는 자연적인 것도 있지만 인위적인 것이 큰 부분을 차지하고 있다. 이러한 재난 재해를 사전에 예방 및 통제를 목적으로 환경정보를 수집하여 위험상태를 판단하기위해 다양한 환경정보수집 무선통신기술에 대한 연구가 활발하게 진행되고 있다. 본 연구는 이러한 목적을 달성하기 위해 다양한 환경정보수집 및 시간 장소 설치 등에 많은 편리성 및 효율성을 갖으며, Ubiquitous Sensor Network(USN)기반요소가 되는 Sensor Network Node를 연구 개발하였고, 이를 이용하여 USN 환경감시 및 통제 네트워크를 구축하여 실험을 통하여 타당성을 입증하였다.

The objective of this paper is to develop an intelligent decision support system that is able to advise disaster countermeasures and degree of incidents on the basis of the collected and analyzed signs of disasters. The concepts derived from ontology, text mining and case-based reasoning are adapted to design the system. The functions of this system include term-document matrix, frequency normalization, confidency, association rules, and criteria for judgment. The collected qualitative data from signs of new incidents are processed by those functions and are finally compared and reasoned to past similar disaster cases. The system provides the varying degrees of how dangerous the new signs of disasters are and the few countermeasures to the disaster for the manager of disaster management. The system will be helpful for the decision-maker to make a judgment about how much dangerous the signs of disaster are and to carry out specific kinds of countermeasures on the disaster in advance. As a result, the disaster will be prevented.

Disaster has a direct influence on the lives of the people, the body, and the property. For effective and rapid disaster responses, coordination process based on sharing and utilizing disaster information is the essential requirement Disaster and safety control agencies produce and manage heterogeneous information. They also develop and use word dictionaries individually. This is a major obstacle to retrieve and access disaster and safety information in terms of practitioners. To solve this problem, standardization of lexical resources related disaster and safety is essentially required. In this paper, we conducted current status analysis about lexical resources in disaster and safety domain. Consequently, we identified the characteristics according to lexical groups. And then we proposed the utilization plan of lexical resources for disaster and safety information management.

We proposal social network service available for disaster and include crowd-soucing in order to improve using only for notification information. Therefore, We design new mash-up which is gathering disaster information from twitter. The mash-up has differences with current systems, because it does not use application software for acquisition disaster information.

With the development of GeoWeb technology, 2D/3D spatial information services through the web are also has been used increasingly in the application of disaster management. This paper is suggested to construct a web-based 3D geo-spatial information mapping platform to visualize various spatial information collected at the disaster site in a web environment. This paper is presented a web-based geo-spatial information mapping service plan for the various types of 2D/3D spatial data and large-volume LiDAR point cloud data collected at the disaster accident site using HTML5/WebGL, web development standard technology and open source. Firstly, the collected disaster site survey 2D data is constructed as a spatial DB using GeoServer's WMS service and PostGIS provided an open source and rendered in a web environment. Secondly, in order to efficiently render large-capacity 3D point cloud data in a web environment, a Potree algorithm is applied to simplifies point cloud data into 2D tiles using a multi-resolution octree structure. Lastly, OpenLayers3 based 3D web mapping pilot system is developed for web visualization of 2D/3D spatial information by implementing basic and application functions for controlling and measuring 3D maps with Graphic User Interface (GUI). For the further research, it is expected that various 2D survey data and various spatial image information of a disaster site can be used for scientific investigation and analysis of disaster accidents by overlaying and visualizing them on a built web-based 3D geo-spatial information system.

This study aims to propose requirements for developing an integrated classification system for disaster and safety information by analyzing classifications currently used in disaster and safety-related organizations in Korea. To do that, this study first analyzed existing disaster category classifications. Then, it collected classifications currently used in disaster and safety-related organizations, and through interviews with practitioners, analyzed considerations to manage disaster and safety information comprehensively. The analysis shows that to develop a disaster category classification, consistency, exhaustivity, systemicity, and disasters frequently occurring in Korea should be considered. In addition, this study suggests a facet classification system for disaster and safety information given the intricacy of disaster and safety management and the occurrence of compound disasters.

This study aims to investigate research trends on disaster safety Information based on the language network analysis methods. To accomplish it, we collected 312 Korean thesis and scholarly articles on disaster safety information published between 2008 and 2017 from RISS (Research Information Sharing Service) site. With the collected data, this study performed the statistical analysis based on bibliographic data. Also, this study performed the analysis of frequency and language network on keyword extracted from titles on the collected scholarly articles and thesis. This study found out that researches recently on Bigdata related to disaster safety information have been rapidly increased. Also, the needs of sharing and utilizing disaster safety information have increased. Also the various types of disaster safety information such as spatial data, real-time information, geographic information has been used for the disaster response.
