현재 전 세계적으로 태풍, 지진, 홍수 등의 재해 피해가 빈번히 일어나고 있고, 4차 산업의 발달로 인한 AI기술을 활용하여 자연재해 전반을 예측 할 수 있는 시스템이 도입될 정도로 과학적으로 발전 되어진 반면에, 재난으로 인한 인명 피해 수를 저감 시키는 방향을 도모 하는 데에는 어려움이 있고, 국민들의 재난피해의식도 심각 하지 않은 추세이다. 이와 같은 문제점을 파악하기 위해 한국 국민 남녀 489명을 대상으로 재난위험인식에 대한 설문을 작성하여 조사를 진행하였다. 본 연구의 목적은 국민들의 재난 안전의 위험도에 대한 인식 수준이 어떠한지 분석하고, 영향 요인을 탐색 하는 데에 있고, 조사결과 안전취약계층은 스스로 대피 하는 데에 있어 큰 어려움이 있으며, 이중 여성은 남성에 비해 안전교육과 훈련의 접근성이 적음에 따라 위험도가 더 큰 것을 확인 할 수 있었다. 본 연구를 통해 재난 안전교육의 필요성을 가지고 재난 안전 시뮬레이션 프로그램이 구축되는 필요성이 있다고 사료되어지고, 미래에 자연재해 발생 시 문제점을 파악하고 인명피해 감소가 될 전망으로 기대가 된다.

In the SORA methodology developed for the operational risk assessment of a specific category of operation of a UAS, the ground and the air risk levels are determined, and a SAIL indicating the level of assurance and integrity for the corresponding risk is assigned, and accordingly, the operational safety level for the proposed operation. Objectives should be demonstrated at an appropriate level of robustness. Because of the nature of the specific category of operation, people on the ground are the first risk subjects to be considered. The resulting ground risk class plays an important role in the allocation of SAIL. In this paper, the impact on SAIL and OSO according to the final risk level and the reduction of the level through the determination of the ground risk level and the application of mitigation measures among risk assessments for specific categories of UAV operation was investigated.

Recently, industrial accidents have continued to increase due to the industrialization, and worker safety management is recognized as essential to reduce losses due to hazardous factors at work places. To manage the safety of workers, it is required to apply customized safety management artificial intelligence technology that takes into account the characteristics of industrial sites, and a service for real-time risk detection and response to workers depending on the situation based on safety accident types and risk analysis for each task and process. The proposed safety management service consists of worker devices to acquire sensor data, edge devices to collect from IoT-based sensors, and a voice chatbot to support workers' disaster response. The voice chatbot plays a major role in interacting with workers at disaster sites to respond to risks. This paper focuses on real-time risk response using an IoT-based system and voice chatbot on a server for work safety according to the worker's situation. A Scenario-based voice chatbot is used to process responses at the edge level to provide safety management services.

Purpose: The purpose of this paper is to analyze accidents and potential risks occurring at container terminals and to conduct on safety management plans tailored to container terminals. Method: A model for establishing a safety management plan is presented through a case study of container terminal risk assessment and literature analysis. Result: According to the 'Statistics of Accidents in the Harbor Handling Industry', 2,800 people were killed or injured during port work for 10 years from 2011 to 2021. This corresponds to an occupational accident rate of one person every 1.5 days. As a method of improving these accidents and disasters, a highly effective safety management plan should be established to prevent the recurrence of accidents in accordance with the Special Act on Port Safety. It is proposed to establish a safety management plan that reflects the risk assessment of container terminals, safety organization, safety budget, safety rules, and safety education.

With remarkable development of industry and technology, various chemical articles are developed to improve the quality of human life, yet some of chemicals are hazardous to human and the environment. However, safety control of chemical articles such as transportation, storage, and handling is emerging as a major issue lately. The road transportation needs well-organized safety management system, especially it has high probability of accidents. In this research, we point out problems in current state and related regulation of transportation of dangerous goods to compare the regulation in UN-RTDG. In addition, we suggest the enhancement law, the plan for standardization of classification in road transportation of dangerous goods and harmonization of labeling in transportation of dangerous goods to contribute to human health and environment protection.

Risk management should be controlled systematically by effectively evaluating and suggesting countermeasures against the various risks which are followed by the change of the society and environment. These days, enterprise risk management became a new trend in the field. The first step in risk analysis is to recognize the risk factors, that is to verify the vulnerabilities of loss in the security facilities. The second step is to consider the probability of loss in assessing the risk factors. And the third step is to evaluate the criticality of loss. The security manager will determine the assessment grades and then the risk levels of each risk factor, on the basis of the result of risk analysis which includes the assessment of vulnerability, the provability of loss and the criticality. It is of great importance to put the result of risk analysis in mathematical statement for a scientific approach to risk management. Using the risk levels gained from the risk analysis, the security manager can develop a comprehensive and supplementary security plan. In planning the risk management measures to prepare against and minimize the loss, insurance is one of the best loss-prevention programs. However, insurance in and of itself is no longer able to meet the security challenges faced by major corporations. The security manager have to consider the cost-effectiveness, to suggest the productive risk management alternatives by using the security files which contains every information about the security matters. Also he/she have to reinforce the company regulations on security and safety, and to execute education repeatedly on security and risk management. Risk management makes the most efficient before-the-loss arrangement for and after-the-loss continuation of a business. So it is very much important to suggest a best cost-effective and realistic alternatives for optimizing risk management above all, and this function should by maintained and developed continuously and repeatedly.

Ensuring the safety of automobiles and trains during system operation is regarded as indispensable due to the progress in unmanned operation. The automotive functional safety standard, ISO 26262, has been proposed to ensure the safe design of vehicles. This standard describes in detail the required risk analysis and evaluation procedure and safety measures, while appropriately reflecting the system design information. Therefore, much research has been done on the risk analysis procedure, wherein the design information is mostly extracted from physical components of similar systems already in operation, the information traced back to obtain constituent functions, and then methods of identifying risk sources are studied. This method allows the sources of risk to be identified quickly and easily, however if the design requirements are changed or systems are newly developed, others may be introduced which are not accounted for, thereby yielding mismatched design information. To resolve this problem, we propose a top-down analysis in order to utilize the system design information appropriately. Specifically, a conceptual system is designed to obtain the functions, which are then analyzed. Then, a function-based fault tree analysis is conducted, followed by a risk source analysis. In this paper, a case study of automotive safety is presented, revealing that the proposed method can analyze the risk sources with reduced possibility of omission by systematically reflecting the system design information.
