The fire department has one of the most important role as public resources of response to disasters in the aspect of supply and the adequate distribution of resources of response is essential, but the distribution of the response capability to disaster of fire department does not reflect the regional hazard vulnerability and hazard risks. Researchers performed database process with simple mapping based on the regional fire disaster response capability and the regional hazard vulnerability and hazard risks. The cities and towns are divided to four types each, total eight types and relative threat ratios are extracted from every type. The fire disaster response capability was extracted from number of firemen and fire vehicles in defined region. The distribution of the fire disaster response capability was inadequate and not matching to relative threat especially in small cities and some types of towns. The regional relative threat and resources should be analyzed by more delicate mapping and software development in the future.

The disaster preparedness system in Korea has been developed in spite of many obstacles, but there are still many problems for response to newly emerging terrorisms due to the existing problems of disaster response system. The newly emerging terrorism in 21th century like biochemical terrorism has made us focus on terrorism preparedness, but health and medical aspect of terrorism has been overlooked. The health disaster system is more necessary for 21th terrorism response as well as the disaster engineering, economic and administrative aspects. The disaster preparedness system for bioterrorism has been developed by Ministry of Health with syndromic surveillance system and no case has been found in Korea yet and the resources of personnel and equipment as decontamination system in medical facilities are lacking in case of chemical terrorism. So through the multiple access method reflecting the risk factors in real terrorism field and human based health disaster concept, the disaster preparedness and response system to make up for the weak point should be suggested.

Reinforcement learning(RL) is the method to find an optimal policy through training. and it is one of popular methods for solving lifesaving and disaster response problems effectively. However, the conventional reinforcement learning method for disaster response utilizes either simple environment such as. grid and graph or a self-developed environment that are hard to verify the practical effectiveness. In this paper, we propose the design of a disaster response RL environment which utilizes the detailed property information of the disaster simulation in order to utilize the reinforcement learning method in the real world. For the RL environment, we design and build the reinforcement learning communication as well as the interface between the RL agent and the disaster simulation. Also, we apply the dimension reduction method for converting non-image feature vectors into image format which is effectively utilized with convolution layer to utilize the high-dimensional and detailed property of the disaster simulation. To verify the effectiveness of our proposed method, we conducted empirical evaluations and it shows that our proposed method outperformed conventional methods in the building fire damage.

Hybrid disaster refers to a type of unexpectedly large-scale disaster that results from continuous or simultaneous occurrence of natural and social disasters. Since hybrid disaster is a completely new type of disaster that has simultaneity and continuity, it requires a different management method compared to the conventional disaster management method. Accordingly, this study suggested policy directions for hybrid disaster response system of Korea after reviewing hybrid disaster response systems in developed foreign nations.

Purpose: The purpose of this paper is to present a method for effectively conducting discussion-based training in disaster response safety training. Method: To this end, we analyzed the disaster response training of developed countries and suggested the training scenarios by applying the war-game process that is currently applied in the operation planning of our military. Result: In one disaster situation, several contingencies could be identified, and supplementary requirements for the manual could be derived. Conclusion: Therefore, in conclusion, if the military war-game process is applied to the discussion-based training in disaster response safety training, effective training can be carried out.

If a disaster occurs in the underground like subway, disaster response system should minimize the casualties. It must quickly guide passengers to a safe evacuation route. But sometimes the system does not work properly. And then they need distributed disaster response system which make decision autonomously. We perform conceptual research about distributed autonomous decision-making disaster detection and response system and disaster detection method.

Recently the frequency of coastal disasters caused by global warming is increasing and the damage is becoming greater. Therefore, the Korean government is establishing various policies and measures to minimize damage. For disaster prevention, this study will evaluate the disaster response capacity of each local resident(Eup/Myeun/Dong) in coastal areas through the survey. The purpose of this study is to quantitatively understand the disaster response capacity and analyze spatial autocorrelation between hot spots(vulnerable area) and cold spots. Thus this study was conducted a survey of 311 towns(Eup/Myeun/Dong) about the disaster response capacity of coastal residents. As a result, Namhae has the highest average score(4.9). On the contrary, Hampyeong has the lowest(1.6). Coastal residents in Namhae seem to have better understanding of first aid and preventive maintenance. But coastal residents in Hampyeong seem to not have these characteristics. Afterwards, this study builds a database of disaster response capacity, and analyzes it using the spatial autocorrelation method. Finally, the area of hot spots and cold spots for disaster response capacity was quantitatively detected.

Purpose: To investigate the perception of paramedic students about core competence and methods of disaster response. Methods: A self-reported questionnaire was completed by 210 paramedic students in Jeollado from March 2 to April 2, 2018. It comprised 57 questions on topics such as general characteristics (6), related experience (11), cognition of core competence (15), and knowledge of disaster response methods (25). Data were analyzed by means of a frequency analysis, a t-test, an ANOVA, and the Pearson's correlation coefficient using SPSS WIN 21.0. Results: The average score of the participants on disaster response core competence was 3.21. The statement "In case of a disaster, I know the duties of medical staff" scored the second highest, at 3.58, and "In the case of disaster, I can conduct the basic treatment" scored the highest ar 3.59. The average score for the disaster response methods was 3.31. Within the section, the statement "I know what I need to do in the case of burn patients" scored 3.59 and "I know what I need to do in the case of a cardiac arrest patient" scored the highest at 3.93. Conclusion: It is necessary to develop a training module considering the diverse types of disasters and a standardized education program for simulation similar to real-life situations.

A first-order moment method (FORM) reliability analysis is commonly used for structural stability analysis. It requires the values and partial derivatives of the performance to function with respect to the random variables for the design. These calculations can be cumbersome when the performance functions are implicit. A Gaussian process (GP)-based response surface is adopted in this study to approximate the limit state function. By using a trained GP model, a large number of values and partial derivatives of the performance functions can be obtained for conventional reliability analysis with a FORM, thereby reducing the number of stability analysis calculations. This dynamic renewed knowledge source can provide great assistance in improving the predictive capacity of GP during the iterative process, particularly from the view of machine learning. An iterative algorithm is therefore proposed to improve the precision of GP approximation around the design point by constantly adding new design points to the initial training set. Examples are provided to illustrate the GP-based response surface for both structural and non-structural reliability analyses. The results show that the proposed approach is applicable to structural reliability analyses that involve implicit performance functions and structural response evaluations that entail time-consuming finite element analyses.

Purpose: For effective crisis communication in the event of a disaster, we present policy measures by exploring what activities are required of companies on a daily basis. Method: Employees working for L company were surveyed about the disaster response department, disaster message, and perception of the company during the company's response to COVID-19, as well as the level of response behavior of the employee. Results: First, caller characteristics did not have a significant effect on behavioral changes of members. Second, while the disaster response message within the company had no effect on the members' normative behavior, it had a positive effect on the discretionary behavior. Third, caller characteristics and disaster response messages had a positive effect on public relations, and public relations appeared to mediate caller characteristics and members' discretionary behavior. Conclusion: Studies on disaster response messages are required in the disaster control tower inside the company in normal times, and activities to build a member-friendly corporate culture for strengthening public relations are needed.
