In this study, we aim to develop a scenario for educational utilization of disaster response robots that can be used at fire sites and analyze the effectiveness of scenarios according to robot utilization education. Our scenarios were developed based on direction, reality, and rationality determined through the use of a questionnaire survey distributed to current firefighters. In addition, the educational utilization of disaster response robots and training effectiveness were analyzed through repetitive robot control training by a robot development team, current firefighters, and college students. Robot control was divided into direct control, monitor control, and simulation control, and tests were carried out five times. As a result of the analysis of the robot control test, the average time spent for each group was 28 seconds for college students, followed by development teams (30second) and incumbent firefighters (38second). According to the individual analysis results, firefighters (maximum 35second) in direct control, the development team (maximum 14second) in monitor control, and firefighters (maximum 22second) in simulation control showed the effect of shortening control time. These results show that robot control education and training is necessary for robots to be used more effectively at disaster sites.

Recently, a series of massive earthquakes have been occurred northeast Asia and there has also been constant sensible earthquakes in South Korea. Particularly, after diagnosing educational facilities with Sichuan earthquake momentum, remodeling construction of old educational facilities and buildings which were not designed not to resist earthquake are actively underway. Remodeling construction sites, however, are mostly small construction sites which consist of less than 30 full-time laborers, where a number of deaths from a fall occur by improper uses of protective gear. Therefore, to reduce the disaster from a fall caused by inadequate uses of protective gear in domestic small construction sites such as those for remodeling, this study conducts research into ways of decreasing accident rates by suggesting providing and administering protective gear as a national project so that donning protective gear is activated.

Negative perceptions of the construction industry are prevalent due to the high accident rate at construction sites. Recently, with the gradual change of the perception in industrial safety, the demand for improving the safety level of construction sites has increased. Accordingly, the government is preparing various safety-level measures such as the Serious Disaster Punishment Act and support for industrial safety management costs. In addition, private industries are incorporating various safety equipment in the sites. This paper introduced the current status of safety sensors and solutions currently applied to construction equipment and industrial vehicles. The technology development direction suitable for construction equipment was introduced by comparing the operating environment of automobiles and construction equipment. and the need to develop performance standards to protect and revitalize the market for safety devices for construction equipment was suggested.

This study is a basic study to improve responsiveness in the event of a disaster in the landside area of the Airport Passenger Terminal, and it investigated the airport emergency plan and the status of emergency response in the event of a disaster by the airline's ground staff. The Airport Emergency Plan examined the airport evacuation plan of Korea's Gimpo Airport and Japan's Ministry of Land, Infrastructure, and Transport, confirming that the domestic airport emergency plan was not specific. In addition, a survey of 100 airline ground employees working at check-in counters found that 69% of the respondents were unaware of their role in disaster situations, 90% were not educated in emergency response and 98% were not trained in disaster training in landside areas. Cross-analysis confirmed significant results in the safety of the airport where the service life worked and whether it was a role in the event of a disaster. Therefore, it is suggested that the airport emergency response plan should be improved to improve the ability to respond to disaster sites in the landside area of the airport passenger terminal and that the airline's ground staff should be educated and trained to enhance disaster response.

In this study, a cloud-based processing method using Agisoft Metashape, a commercial software, and Amazon web service, a cloud computing service, is introduced and evaluated to quickly generate high-precision 3D realistic data from large volume UAV images acquired in disaster sites. Compared with on-premises method using a local computer and cloud services provided by Agisoft and Pix4D, the processes of aerial triangulation, 3D point cloud and DSM generation, mesh and texture generation, ortho-mosaic image production recorded similar time duration. The cloud method required uploading and downloading time for large volume data, but it showed a clear advantage that in situ processing was practically possible. In both the on-premises and cloud methods, there is a difference in processing time depending on the performance of the CPU and GPU, but notso much asin a performance benchmark. However, it wasfound that a laptop computer equipped with a low-performance GPU takes too much time to apply to in situ processing.

This study intends to provide a model for the establishment of a rehabilitation room for the safety and rehabilitation of firefighters by proposing a basis for the establishment of a firefighter rehabilitation room at disaster sites. To achieve the research objectives, a questionnaire, frequency analysis, and variance analysis were conducted to assess the effectiveness of rehabilitation rooms for firefighters. Based on the results of the research, the policy suggestions for operating an effective rehabilitation room are as follows. An organization of the operation of the rehabilitation room should be established at each firefighting headquarters, and human resources must be secured for the operation of the rehabilitation room. In addition, detailed operating standards such as the operation contents of the rehabilitation room's operation manager and its operator, as well as its operation procedures should be prepared. Additionally, training to improve the rehabilitation room and its understanding is needed.

According to the recent "Status of Industrial Accidents at the End of December 2020" released by the Ministry of Employment and Labor, each industry is subject to industrial accidents. The number of accident deaths by construction industry, accident deaths by accident type fell, and accident deaths by workplace size were 5 to 49, indicating that most accident deaths occurred due to falling accidents at small construction sites. Therefore, urban living houses are small construction sites, and the probability of falling accidents is very high. Fall simulation training for disaster occurrence is conducted mainly by large construction ordering organizations in the public sector, and it is the first case in Korea that a housing construction company has conducted at a small construction site. This study analyzed and presented the definition, construction characteristics, and safety management status of urban living houses, and developed and spread an emergency relief procedure manual in the event of a fall accident to minimize deaths.

Purpose: Mobile cranes are machines that contribute to high mortality, and the High Risk Factor (SIF) information, which analyzed 2,574 accidental deaths in the construction industry in the past 6 years (2016~2021), resulted in a total of 61 mobile crane accidents. Despite safety measures in the field, it is not used properly. In this study, we present standard risk assessment indicators that contribute to accident prevention. Method: Through expert interviews, fatal accident case analysis, field analysis, and literature research, we present the standard risk assessment index method of the 4M risk assessment method. Result: As a result of analyzing the risk assessment of eight sites, it was concluded that it cannot make a significant contribution to disaster prevention and should be applied as an improvement measure of the Standard Risk Assessment Index Law. Conclusion: Switching to the standard risk assessment index method at construction sites has been proposed to make it easier for health and safety personnel and workers to use, contributing to the reduction of accidents.

In this study, the risk of landslides was analyzed for planned development sites in mountainous areas. Field survey was conducted on the research area with the slope and valley site. The criteria for evaluating the risk of landslides in the field survey were based on the risk assessment table of the Korea Forest Service Notice No. 2023-10. The research area has 13 slopes and 11 valleys. As a result of evaluating the risk area, two slopes and two valley were found to be dangerous sites in each. Numerical simulation was performed on the investigated risk areas to predict the spread of damage. The debris flow was simulated to have an affect on roads and buildings located in the lower part of the basin, and it was determined that a disaster prevention facility was nacessary to minimize damage. This information can be used to determine the impact of disasters before carrying out mountain development.
