본 논문은 2008년 12월 5일 경기도 이천시 소재의 물류창고 화재사고에 대한 화재원인 및 화재확대요인을 검토하고, 재발방지를 위한 대책을 제시하였다. 본 화재원인 검토결과 용접작업 실화에 의한 화재로 벽체패널인 샌드위치패널과 문틀형 강을 접합하던 중 용접작업시 발생하는 불티 또는 고열에 의해 벽체패널 내부의 스티로폼 및 우레탄폼에 착화된 것으로 추정된다. 화재확대요인은 화재에 취약한 스티로폼 및 우레탄폼 재질의 샌드위치패널 사용과 소방설비의 인위적 기능해제로 판단된다. 이번 사고와 같은 재난을 예방하기 위해서는 급격한 연소확대 특성을 갖는 스티로폼 및 우레탄폼 재질의 샌드위치패널 사용금지, 소방설비의 기능해제에 대한 감시와 처벌강화와 안전관리체계 및 안전규칙 준수여부 관리 강화가 필요하다.

Digital Twin, one of the core technologies of the Fourth Industrial Revolution, is attracting attention as a very suitable technology for disaster monitoring such as fires and earthquakes. In this paper, we implement a system equipped with UWB RTLS(Ultra-Wideband Real Time Location System), real-time remote control, and video streaming, which are element technologies for disaster monitoring digital twin. Since the proposed system structure is based on a cloud server, the actual location of the UWB indoor positioning-based client is transmitted to the user device in real time and stored on the cloud server for statistical and data analysis. In addition, we demonstrate through experiments that outliers occurs when the value of RSSI(Received Signal Strength Indicator) decreases due to communication collisions between UWB Tags, and propose an RSSI outlier correction algorithm to solve this problem.

In this dissertation, a we designed and implemented a patrol robot that integrates a thermal imaging camera, speed dome camera, PTZ camera, radar, lidar sensor, and smartphone. This robot has the ability to monitor and respond efficiently even in complex environments, and is especially designed to demonstrate high performance even at night or in low visibility conditions. An orbital movement system was selected for the robot's mobility, and a smartphone-based control system was developed for real-time data processing and decision-making. The combination of various sensors allows the robot to comprehensively perceive the environment and quickly detect hazards. Thermal imaging cameras are used for night surveillance, speed domes and PTZ cameras are used for wide-area monitoring, and radar and LIDAR are used for obstacle detection and avoidance. The smartphone-based control system provides a user-friendly interface. The proposed robot system can be used in various fields such as security, surveillance, and disaster response. Future research should include improving the robot's autonomous patrol algorithm, developing a multi-robot collaboration system, and long-term testing in a real environment. This study is expected to contribute to the development of the field of intelligent surveillance robots.

This paper introduces analyzing the feature of drowning accidents in Korea and reviewing the method for reducing it. A lot of drowning accidents happen at inland areas such as lakes and rivers in Korea. Also, when the accident happens, systematic notify and rescue activity are carried out, but in terms of an accident prevention, there are many problems such as lack of management manpower and the difficulty of continuous monitoring about dangerous areas, etc. In order to resolve the problems about prevention of drowning accidents and the lack of the management, the role of the local governments is important, and using the ICT technology, it is effective to make use of monitoring remotely dangerous areas and developing control technology.

The 14 cities and guns within Gangwon-do were divided into three regions (urban-rural-integrated type, urban type, and ruralcoastal type), and local voluntary disaster prevention organizations in those regions were surveyed as sample groups. As a result, the urban-rural-integrated type and the urban type were found to be lower than the rural-coastal type in all domains including recognition of disaster crisis, evacuation guidance, preparation of voluntary evacuation, maintenance of disaster prevention system, surveillance & guard, and information delivery. In particular, three types had higher information delivery but considerably lower preparation of voluntary evacuation. As for information delivery, foundations for rapid delivery of disaster information due to establishment and extension of systems for forecasting and warning of local governments were prepared, but as for preparation of voluntary evacuation, it is needed not only to perform consistent training and promotion for preparation for disasters for residents to accurately understand status of disasters but to take measures to secure safe places for evacuation beforehand.

Government ministries operate various system dealing with filed civil appeals. There are representative systems such as Safety Monitoring System of the Ministry of Public Administration and Security (MOPAS), Disaster Premonitory Information System of the National Emergency Management Agency (NEMA), Facilities Hazard Information System of the Ministry of Land, Transportation and Maritime Affairs (MLTM), Environmantal Monitoring System of the Ministry of Environment (ME). The purpose managing these systems is to reduce casualties and to improve safety by preventing disasters and accidents in local communities. This study suggests the method to effectively operate a safety monitoring system which fits to local situations based on the statistical analysis performed on filed complaint cases in Gangdong-gu as a sample region. The cases has been collected since 2012 through the voluntary safety monitoring activity of a specialist who had finished the Emergency and Safety maneger's master course.

Recently, Internet use is increasing in various fields. Especially in the sudden disaster area, the role of Internet of things that can continuously monitor is getting bigger. In this study, the characteristics of the confined space and the environmental hazards are examined, and the Internet of the object which is being commercialized will be reviewed. Accidents in confined spaces are very high compared to other places, and it is very difficult to predict accidents. Recently, various attempts have been made to prevent accidents in confined spaces using the Internet of things. Especially, it detects the various gases that can occur in the closed space using sensors and sends them to the workers in real time, so that the risk can be detected in advance to minimize the risk. In this paper, we propose an effective disaster prevention plan using the Internet of things through the case study of the Internet for the prevention of accidents in a confined space.

Global interests for construction of 3 dimensional spatial information has risen due to development of measurement sensors and data processing technologies. In spite of criticism for the violation of personal privacy, CCTV cameras equipped in outdoor public space of urban area are used as a fundamental sensor for traffic management, crime prevention or hazard monitoring. For safety guarantee in urban environment and disaster prevention, a surveillance system integrating pre-constructed 3 dimensional spatial information with CCTV data or video sequence is needed for monitoring and observing emergent situation interactively in real time. In this study, we proposed applicability of the prototype system for web visualization based on X3D, an international standard of real time web visualization, by integrating 3 dimensional spatial information with video sequence.
