PURPOSES : Recently, interest in radioactive accidents has increased due to domestic and international nuclear power plant accidents. In particular, local residents' concerns are increasing due to safety issues such as radioactive leaks at the Hanbit Nuclear Power Plant in South Korea. As Gwangju Metropolitan City is not included in the emergency planning area set by the Nuclear Safety and Security Commission, there are significant limitations to establishing disaster prevention measures for nuclear power plant accidents. Considering the Fukushima and Hanbit nuclear power plant accidents, the improvement of Gwangju Metropolitan City's radioactive leak accident response manual is urgently required. This study aimed to establish disaster prevention measures to respond to nuclear power plant accidents in Gwangju Metropolitan City in the event of a Hanbit Nuclear Power Plant accident and to improve resident protection measures by estimating the arrival time of radioactive materials and radiation dosage through a nuclear power plant accident simulation. Additionally, we aimed to supplement the on-site action manual for radioactive leaks at the Hanbit Nuclear Power Plant. METHODS : This study focused on establishing disaster prevention measures centered on Gwangju Metropolitan City in the event of a major accident such as a radioactive leak at the Hanbit Nuclear Power Plant. Simulations were conducted assuming a major accident such as a radioactive leak, measures to improve resident protection were established by calculating the arrival time of radioactive materials and radiation dosage in the Gwangju area in the event of a nuclear power plant accident, and on-site response action manuals were supplemented in response to a radioactive leak. RESULTS : This study considered the concerns of local residents due to the Fukushima nuclear power plant accident and the Hanbit nuclear power plant failure, conducted a simulation to derive the impact on Gwangju Metropolitan City, and examined the effectiveness of an on-site response manual for radioactive leaks to derive improvement measures. CONCLUSIONS : In the event of an accident at the Hanbit Nuclear Power Plant in Gwangju Metropolitan City, insufficient portions of the on-site response action manual should be supplemented, and close cooperation with local governments within the emergency planning area should be ensured to respond to radioactive disasters. Therefore, based on the revised on-site response action manual for radioactive leaks, close cooperation and a clear division of roles among local governments will enable effective resident protection measures to be implemented in the event of a radioactive disaster.

일반차량과 자율주행차량이 혼재하는 상황에서 발생가능한 미래 재난상황에 대한 관리방안 준비가 필요하다. 특히 재난 상황 중 안 개 발생 시 시야 확보가 어려운 일반차량 운전자와 센서기반 자율주행차량의 주행 특성이 다를 수 있다. 해당 상황에서의 문제점을 도출하고 이를 극복하기 위해 혼합교통류 관리 방안을 제안하고자 한다. 본 연구에서는 다양한 재난 상황 중 안개를 연구 대상으로 설정하였다. 과거 기상 상황별 일반차량을 주행 특성을 이력자료로 분석한 후, 안전한 교통흐름을 유지하기 위하여 자율주행차에게 정 보를 제공하는 방안을 제안한다.

자율주행차가 보급되어 도로에서 사람 운전자와 함께 운영되는 미래가 다가오고 있다. 사람 중심으로 운영되는 도로 체계가 자율주 행차와 공존하는 형태로 변화하고 있으며, 도로 시스템도 사람 운전자와 자율주행차가 혼재된 혼합교통류를 대상으로 변화하고 있다. 현재 도로에서는 예상하지 못한 상황들이 다양하게 발생한다. 교통사고, 도로 낙하물 등 교통흐름에 영향을 주는 상황들이 발생하며, 대응을 위한 전략들이 각 지방자치단체에서 준비되어 있다. 미래 교통상황에는 도로상에 자율주행차가 혼재되어 있으며 이를 포함하 는 돌발 및 재난상황에 대한 제어전략은 아직 부재하다. 본 연구에서는 돌발 및 재난상황 발생 시 자율주행차 제어전략에 대한 설계 방안을 제안한다. 돌발 및 재난상황 범위에 대해 정의하며, 상황 구분을 위한 기준을 제시하여 각 상황에서 자율주행차가 안전하게 대 응할 수 있도록 제어전략을 제시한다.

As the distribution of vehicles and logistics increases due to the development of human civilization and the increase in population, various roads play an important role in domestic traffic and transportation. However, the recent emergence of large cities and new cities is causing traffic problems, and the increase in roads is inevitable for the smooth distribution of vehicles and logistics. In Korea, mountainous regions occupy 70% of the country, so tunnels are used to open roads. Without this, it is difficult to open the road. Currently, there are 3,720tunnels (as of December 31, 2023) installed on high-speed national highways, general national highways, and local roads nationwide, with a length of 2.499 and increasing every year. Accordingly, fire accidents in tunnels will also increase, and due to the nature of tunnel fire accidents, there is a high probability that they will escalate into large-scale disasters, resulting in casualties and property damage, as well as significant social losses due to the disruption of logistics transportation, etc. As the possibility of potential hazards is increasing, the purpose of this study is to build a safe and efficient tunnel system by optimizing maintenance and management for fire and disaster accidents in tunnels.

본 연구는 재난 피해자의 회복에 주요한 영향을 미치는 연령별 특성별 차이를 고려하여 재난 피해자의 회복탄력성 결정요인을 실증적으로 검증 하고자 시도되었다. 이를 위해 2022년 국립재난안전연구원에서 수집한 재난피해 회복수준 실태 조사의 자료를 활용하여 사회적지지(가족, 친구, 이웃), 지역애착성을 독립변수로 상정하고, 연령대별로 회복탄력성에 어 떠한 영향을 미치는지를 분석하였다. 분석결과 모형1인 일반인에서는 성 별, 연령, 직업유무, 사회적지지의 하위요인에서는 가족, 친구, 이웃이 통 계적으로 유의했고, 모형2인 노인에서는 성별, 최종학력, 직업유무, 사회 적지지 하위요인 중 가족이 유의하였다. 재난 피해자 모형3인 전체에서 는 거주기간을 제외한 모든 변수가 통계적으로 유의하였다. 이는 재난피 해자의 회복을 위해서는 본인이 살고 있는 지역(동네)에서 거주하는 것이 좋으며 가족, 친구와 같은 친밀성을 확보한 지지체계는 효과가 있으나, 이웃은 오히려 회복에 부적인 영향을 줄 수 있다는 결과이다. 분석 결과 를 통해 재난 피해자의 회복을 위해 연령대별 재난 피해자 회복 전략 수 립의 필요성과 재난 피해자의 거주지 지원제도 개선에 대해 제언하였다.

PURPOSES : This study aims to propose drone-command standard operating procedure (SOP) guidelines and Analyze their potential application to increase the use and utility of drones in urban disaster situations. Although the effectiveness and efficiency of obtaining disaster-situation information through drones have been verified by previous studies and practical experience, a survey of actual drone usability indicated a utilization rate of only approximately 4.13%. METHODS : To provide guidance for improving drone command SOPs, prior research and relevant literature were reviewed to identify commonalities between disaster-response command and control and drone use. A sample of 73 active-duty firefighters, including incident commanders (ICs) and drone pilots, were surveyed and interviewed. The data were analyzed and categorized to establish the reasons why drones are not actively used in urban disaster-response procedures. RESULTS : The primary reasons identified for not actively utilizing drones in urban disaster areas were the lack of a drone command and control system and the lack of clear criteria for when to use drones in disaster situations. In addition, many problems were found in drone-operation procedures, including emergency flight approval, securing takeoff and landing sites, and accident burden due to urban flight obstacles. To address the issues identified, standards were proposed for the type, size, and scope of urban disasters requiring drone response; for accident-prevention on basic missions and through flight safety procedures; and for installing a video transmission and reception system to easily share drone video information with ICs. CONCLUSIONS : Application of the drone-command SOP guidelines to actual urban disaster situations by disaster type will help to improve the efficiency of information acquisition and flight safety. This is expected to enable increased drone utilization. In future, extension of the research reported in this paper beyond the Seoul metropolitan area via additional follow-up studies has the potential to establish applicability of the proposed SOP guidelines to a wide variety of environments and organizational characteristics.

기후변화는 연안지역에 심각한 영향을 미치고 있으며 그 영향이 점점 증가할 것이라고 예상되는 바, 최근 기후변화 적응 및 리스크 평가에 있어 많은 연구들이 취약성과 함께 회복탄력성 개념을 이용하고 있다. 본 연구의 목적은 기후변화 적응을 위한 연안재해 회복탄력성 측정 모형을 개발하는 것이다. 측정 모형 개발에 앞서 연안재해 회복탄력성에 대한 광범위한 문헌검토를 통해 취약성과 회복 탄력성에 대한 조작적 정의와 함께 여러 피드백 메커니즘이 포함된 개념적 프레임워크를 작성하였다. 연안재해 회복탄력성 측정 모형은 네 가지 측정값(MRV, LRV, RTSPV, ND)과 연안재해 회복탄력성 복합 지수(CRI)를 포함하고 있으며, 개발된 지수는 국내 연안침식 사례에 적용되었다. 또한 지수 등급에 따른 지역적 분석이 수행되었다. 연구 결과, 네 가지 회복탄력성 측정값을 통해 각 지점이 가지는 연안침식 회복탄력성의 다양한 특성을 파악할 수 있음을 확인하였다. 연안 회복탄력성 복합 지수의 매핑 결과 서해안 및 남해안 지역에 비해 동해 안 지역들은 연안침식 회복탄력성이 상대적으로 떨어지는 것으로 나타났다. 본 연구의 회복탄력성 측정 모형은 적응 이후의 이행전략에 대한 논의를 제공하는 도구로 활용될 수 있으며, 서로 다른 취약 지역 그룹 간 정책지원에 대한 우선순위를 결정하는 데 이용 가능하다.

Indonesia is a disaster-prone archipelagic country and one of the world's largest emitters. Climate change has increased the risk of disasters in Indonesia, such as rising sea levels leading to floods. This is undoubtedly a threat to the Indonesian population in coastal areas and small islands. They will be forced to become Internally Displaced Persons (IDPs) if sea levels continue to rise and drown their houses. The number of IDPs in Indonesia has increased significantly in recent years. While IDPs have a legal status and are entitled to protection from the state, there is unfortunately no specific provision for IDPs due to climate disasters in Indonesia. This article examines the legal protection afforded to IDPs in Indonesia as a result of climate-related disasters; deals with the existing legal framework for IDPs; and assesses its adequacy in addressing the specific challenges faced by climate-related IDPs.

Recently, there are some outdoor floor advertising lighting devices as one of the active marketing methods. However, for outdoor use, there are many restrictions due to the Outdoor Advertisement Act, according to requiring high-output heat generation, waterproofing, and AC power, etc. The purpose of this study is to develop a Duo Light product optimized for indoor use through publicity and information guidance in normal times and automatic evacuation route guidance display in case of disaster, in conjunction with disaster safety. To that end, patent search and patent association analyses were conducted, and a comparative analysis with commercial products was conducted as a case study. In addition, prototypes were designed and produced through the review of operation principles, where field environment surveys and self-tests were conducted. Also, technology roadmaps were presented by preparing plans for expandability and advancement of products. For the analysis of technology commercialization, the feasibility of technology commercialization was examined through the analysis of Jolly’s Model and Lean Canvas Model. The results of this study will be able to contribute to minimize human damage through the effective response to disasters, which can increase the effect of indoor advertising by using the proposed indoor floor advertising lighting device in advertising and disaster situations.

본 연구는 경로의존성과 정책선도자의 개념으로 최근의 주요 경비업 법 개정 관련 논란 및 사태 등을 살펴, 10.29 참사 이후 경비업법 개 정 관련 논의를 하고자 한다. 이를 위해 각종 논문 및 학술자료와 신문 기사 등 자료를 통한 문헌분석 방법을 통해 살펴본다. 경비업법은 경비 업 제한(지도와 감독, 규제와 처벌 논리)법으로서 기능을 하여 왔으며, 경비업의 권한 남용의 방지에 관한 광범위한 기술적인 규정을 두는 경 로의존성을 지니고 있으며, 경비업법에서 정책선도자인 행정안전부(경 찰청)의 역할과 기능은 매우 중요함을 알 수 있었다. 결국, 경비업법의 경로의존성은 개정 입법 논의의 한계로 작용하고 정책선도자인 행정안 전부(경찰청)의 의지에 달렸다. 최근 10.29 참사로 인해 경비업법의 개 정에 대한 정책의 창이 열렸다. 그간의 경비업법 개정 과정 분석을 통 해 경로의존성과 정책선도자의 특성을 고려해 본다면, 개정의 논의가 순탄치 않음을 탐색해 볼 수 있다.

This study attempted to analyze the comparative advantage in terms of disaster safety costs in verifying the effectiveness and economic feasibility of the high-performance water-bulwark system in the pole tunnel, which was recently promoted as a part of the acceleration of vehicles. The tunnel to be analyzed was divided into a short tunnel(Anyang, Cheonggye) and a long tunnel(Suraksan, Sapaesan). As a result, it was analyzed that 25% of the improvement effect would occur if one lane was secured by applying the Water-Bulwark System. It was analyzed that this is because the time value cost, which accounts for a large proportion of the traffic congestion cost of short tunnels and pole tunnels, differs depending on the congestion time and traffic volume, not the length of the tunnel.

This study is to investigate the degree of field awareness of how each provision of the Serious Disaster Punishment Act will affect accident prevention. As a result of conducting a survey of construction site workers, it was analyzed that construction site workers had a low sense of safety and did not voluntarily engage in safety activities. And it can be seen that they are taking a very passive position that it is efficient to implement safety under the supervision of the supervisor. Workers who need voluntary construction site safety activities are most aware of the situation at the site, but the problem was pointed out as “lack of procedures for listening to opinions and preparing improvement measures” for these problems. Future research is needed to see if this is a problem for individual workers or for those in charge of safety and health who do not correct it even though active opinions have been submitted.

Mt. Umyeon is a low-altitude mountain near a residential area, and the actual forest area is not large due to the fact that development for use as a living green space is being completed and in progress across the mountain, so the buffering action for landslides was weak. The unit was located at the top of Mt. Umyeon, and there were reports of contents related to the military unit in some accident areas. Some experts suggested that the landslide that started on the cut side of the unit could be one of the causes of the landslide at Mt. Umyeon. It is presumed that there was a sudden collapse of trees that had fallen due to erosion inside the valley. In the case of the Umyeon landslide, localized torrential rain is the biggest cause, but the fact that it suffered a lot of damage is the result of no preemptive measures. In particular, it can be said that the damage was caused by the concentration of residential and commercial facilities due to the unplanned urban expansion without prior review of the feng shui geography of settlement areas. The important lesson we have learned is that we should recognize nature as living things and live in harmony and coexistence between humans and nature through understanding and cooperation. Adapting to changes in the environment can survive, but if it doesn't, it will be slaughtered. As such, geography influences changes in feng shui. Changes in feng shui have a profound effect on not only humans but also the natural ecosystem.
