In Korea, natural disasters such as earthquakes and floods continue to occur, but it is difficult to respond and provide relief effectively and promptly. Due to the Circulation Position and administrative characteristics, soft and physical systems for basic disasters, such as private cooperation and disaster response bases, have not yet been built organically. This is mainly due to the job rotation of the responsible persons and bureaucratic problems limiting cooperation between the public and private sectors. Japan is responding to disasters through a mutual cooperation network between the public and private sectors (NGOs), but in Korea the public sector still manages disasters entirely by itself. However, in modern society, the ability of the public sector to effectively manage disasters is limited due to the large number of natural disasters and their wide-ranging consequences. This situation makes it difficult to respond quickly and effectively to the various crises that arise. In this paper, we review the disaster response bases in the cases of Japan and the United States, and propose the establishment of a disaster response base system that supports disaster countermeasures together with a cooperative network incorporating the private and business sectors.

Various disasters have been continuously occurred in Korea from 1990s to now. However, there is no substantial improvement against damages as compared with the past due to various reasons such as lack of fundamental recognition, ineffective response systems and widespread insensitivity to safety. More worse, new types of disasters have been frequently generated due to rapid changes in social structures and industrial development, unusual changes in weather and changes of international situations. These disasters request comprehensive countermeasures. In particular, while material damages by disasters can be recovered, the losses of precious lives cannot be recuperated in any ways. Thus, it is critical to set effective disaster medical plans. The first way to minimize damages by disasters is the prevention and the next is to set the disaster medical plans focusing on preliminarily activating the emergency medical system to rapidly rescue and take appropriate emergency medical services for casualties in the early stage when any disaster occurs. Nevertheless, no sufficient researches or references do not exist up to now. Even worse, effective emergency medical systems that play critical roles in increasing survival rates of casualties in actual disaster areas is not deployed. For the United States, the consistent countermeasure system is established in FEMA through a close cooperative system with relevant organizations for serious accidents including terrorists' attacks or natural disasters. For the emergency medical services in disasters, the disaster medical plan is set to cope with any disasters in perfect order by special area as operating the National Disaster Medical SystemESF#8 Role by FEMA. Accordingly, we need to set the extensive and integrated disaster prevention system for rapid and flexible operation against various kinds of serious accidents. This study identified overall problems in disaster control plans in Korea and suggested how to improve the emergency medical service system in disaster areas. Furthermore, it aims to prepare the basic data to set the effective emergency medical service plans when substantial casualties break out and more reasonable and systematic disaster control plans to cope with the future occurrence of serious disasters.

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.

Construction sites have various risks, and safety managements are enforced based on the law such as Industrial Safety and Health Act, etc. Safety management by the law saves lives and preserves health of workers by removing and understanding risks in advance. When the emergency situation has come, poor response causes loss of lives and physical damages. This study suggests basic strategy that can mitigate the industrial disaster in all construction sites. A survey was conducted to identify the current safety consciousness and to evaluate first aid ability of coworkers. Finally, four measures were suggested: (1) designating muster points; (2) hiring occupational health managers; (3) increasing the first aid ability of coworkers; and (4) carrying safety brochure. The proposed suggestions can be helpful in mitigating the construction disaster, and in responding the major accident efficiently within a short time.

The suggestions that follow are about the Qualitative Improvement of private security Industrial. First, in legal and institutional policy, new establishment by law for private security and more support from government is asked. Moreover, the restructuring or M&A between petty companies and the pricing for security service should be performed. Second, in the structural aspect of private security industry, the professional education center for private security guards should be established and the terms of payment and welfare should be improved to the level above standard. In addition, it should be achieved to change the public to have a new and correct understanding of private security and develope the specialized parts suited to the characteristic and ability of each companies. Third, the construction of operating system for private security service should be achieved; recruit system for competent security guards, marketing strategy and enforcement system, widely known confidence to client, normal training system for security guards and post management system for client. This is also to be suited to the characteristic of each companies.

Drone is currently used for wide application areas in our real life. Also it performs more important functions. We propose a method of drone operation system for the prevention of industrial disaster. In normal operation of drone system the drone monitors the industrial sites according to the planned flight path with acquiring the monitored images and send the image information to the server. The server analyzes and compares the images to DB information by calculating the similarity based on the threshold. Then the system decides whether the industrial sites has problems or not. If the abnormal condition is occurred, the drone change the flight path to abnormal flight path and keep monitoring the industrial sites with measuring the air status by sensors and sends all information to server system on the ground. If the emergency case is occurred, drone approaches the closest position of accident points and acquiring the all information and send them to server and 119 center.

Recently, as the frequency of natural disasters has increased, causing enormous human and material damage, the importance of managing disasters is emphasized. In particular, as the concept of Build Back Better becomes meaningful, it has appeared that considering it during Post-disaster Reconstruction is a necessity. Therefore, in this study, the relative importance evaluation and correlation analysis were performed for each influencing factor through the derivation of the influencing factors that should be considered during the reconstruction approach stage of reconstruction after disasters, and a survey of overseas disaster-related experts. As a result of the analysis, 'Adaptability to the environment changes in the future was derived as the most significant influencing factor. It seems that the results of this study can be used as basic data when carrying out the reconstruction project.
