In industry society, it is challenging to identify and prevent potential hazard factors since an industry is complex and changing variously. Particularly, as industrial accidents occur more frequently by secondary and tertiary indirect causes, rather than primary direct causes such as environmental changes or selfinduced disasters, it becomes more difficult to analyze the risk in safety management perspective. The purposes of this study are to reconsider the variable factors used in the existing Risk Priority Number (RPN) assessment method and to explore a new prioritization method for risks and disasters caused by various external environmental changes. To achieve this, various variables are considered including the currently used variables such as the occurrence frequency, the likelihood of occurrence, the severity. Among the variables, the eight key variables will be selected, and it is to take account of the relative weights between the variables.

In small and medium-sized enterprises and small service enterprises, environmental, social and governance(ESG) is perceived as an abstract and broad in perspective of management, and there is lack of specific methodologies to implement ESG management philosophy. Especially in safety-prioritized industries such as manufacturing, construction, and electricity where the Severe Disaster Punishment Act directly applied, many companies are studying which aspect should be emphasized to establish practical safety culture and system in the organization. This research suggests the evaluation items, using the Analytic Hierarchy Process(AHP), to settle the industrial safety and the safety culture that a small size enterprise executes ESG management.

This study investigates the gap between statutory calculation standards and actual field conditions in estimating Occupational Safety and Health Management Expenses (OSHME) for large-scale construction projects. The current fixed-rate method, based on construction type and cost, fails to account for on-site factors such as project complexity, duration, and workforce structure, often leading to discrepancies between estimated and actual costs. To address this, data from 21 completed projects over KRW 5 billion were analyzed. Multiple regression analysis was conducted using variables including material and labor costs, project duration, floor area, number of floors, and the number of safety personnel. The results showed a significant statistical difference between calculated and actual OSHME, and the proposed model explained 95.3% of the variance (R2 = 0.953). Variable selection techniques were applied to improve prediction accuracy by addressing multicollinearity. The model offers practical value for early budgeting and supports policy improvements that align safety expenses with real on-site needs, in order to more effectively prevent industrial accidents.

Neighboring living facilities and commercial housing have increased along with the rapid expansion of the city. However, unlike general apartment complexes and planned cities, most buildings are built on a narrow site in neighborhood living facilities and commercial housing areas, so securing sidewalk blocks, which are pedestrian passages, is insufficient. The water supply fire hydrant installed in such a narrow sidewalk block has become an obstacle to pedestrian traffic. As a result of the survey, 62% of the walking passages in places where water supply fire hydrant (including protective frames) are installed in the sidewalk block were less than 1.5m. The "Rules on Road Structure and Facility Standards" stipulate that the minimum width of the sidewalk block is 2m or more, and the obstacles and effective width of passage are 1.5m or more. In addition, it was confirmed that the protective frame was interfering with the connection of the fire hydrant hose according to the media reports and the actual results of this study. Therefore, it is necessary to secure a space where the water supply fire hydrant can be used smoothly in case of fire and a safe walking passage, and to manufacture a protective frame, establish construction standards, and prepare legal and institutional standards for efficient maintenance.

In this study, chemicals with acute toxicity experimental data were selected as research subjects, and compareed the model derived from statistical analysis and QSAR open-source programs. The physical and chemical properties, dynamic behaviors, and toxicological estimates of the chemicals were calculated using Mordred, a molecular descriptor calculation program based on RDKit. LD50 was set as the toxicity comparison target for each chemical, and independent variables or factors with similarity to independent variables were estimated from the molecular descriptors calculated through Mordred. Molecule descriptors composed of independent variables were compared to predictions from QSAR open-source models, A regression model was created with the selected molecule descriptors and compared with predictions from QSAR programs, confirming high accuracy for specific functional groups. The QSAR model created in this study considers the characteristics and experimental values of each chemical, and provides evidence for selecting variables when constructing toxicity data for machine learning applications.

This study analyzed fall accidents involving boatswain’s chairs over the past ten years to investigate their underlying causes and effective preventive measures. The fall accidents in this study were classified according to construction type, work category, and sequence of work. Next, their direct causes were identified by applying the concept of serious injury factor. A focus group interview was conducted with six experts in boatswain’s chair-type scaffolding to derive preventive measures. The results of the investigation indicate that the majority of accidents occurred in maintenance works among construction types, and painting, caulking, and cleaning tasks among work categories. In terms of work sequence, most fall accents occurred while working with descending due to rope defects (loosening, breakage, or insufficient length) and anchorage failures. Based on these findings, two key preventive measures were proposed: (1) installing lifelines as a fail-safe measure to provide safety redundancy, and (2) implementing inherent safety measures to prevent rope defects and failures such as regular inspections, use of high-performance ropes, and ensuring proper anchorage strength. The findings of this study can be utilized in development of effective safety guidelines and policies for boatswain’s chair operations.

This study experimentally and numerically evaluated the fire risks and structural vulnerabilities of tunnel-type noise barriers (hereinafter referred to as hereinafter referred to as soundproof tunnels). In Korea, soundproof tunnels are typically constructed using combustible polymeric materials such as polymethyl methacrylate (PMMA) and polycarbonate (PC) for noise reduction and lightweight design. However, due to their enclosed structural characteristics, concerns have been raised regarding heat and smoke accumulation as well as the rapid spread of fire. In this study, fire scenarios were established by varying structural conditions, including roof opening ratios and the presence or absence of central partitions, and analyzed using the Fire Dynamics Simulator (FDS). The results demonstrated that PMMA exhibited a lower thermal decomposition temperature and a higher heat release rate, indicating a higher level of fire risk, while PC showed superior fire resistance with higher decomposition temperature and delayed ignition properties. PMMA rapidly exceeded the critical thresholds for temperature and radiative heat flux, resulting in complete combustion. Central partitions were found to accelerate smoke spread, whereas side or roof openings facilitated smoke discharge to the exterior, contributing to fire suppression and improving life safety. In conclusion, this study confirmed that the fire risks of soundproof tunnel are jointly influenced by the combustion characteristics of the materials and the structural conditions. The findings are expected to serve as fundamental data for material selection and design standard improvements in future soundproof tunnel fire safety.

This study evaluated the effectiveness of fire safety education in high school dormitories—high-density residential environments—by assessing both cognitive and behavioral changes. Pre- and post-surveys were combined with measurement of the Required Safe Egress Time (RSET), which recorded 264 seconds from alarm activation (T₀ + 0 sec) to final evacuation completion (T₀ + 264 sec). This enabled a quantitative analysis of behavioral improvement. Results revealed that academic performance and family background significantly influenced learning outcomes, whereas the “evacuation during fire” domain showed no statistically significant change, suggesting insufficient instructional content or delivery. Policy recommendations include customized fire safety programs reflecting learner characteristics, experiential evacuation drills, school–home safety integration, mandatory dormitory fire drills, and certification with best-practice dissemination. The findings offer a practical framework for enhancing fire safety education tailored to dormitory-based schools, contributing to improved preparedness, response capability, and student survival in real fire emergencies.

This study quantitatively analyzed the effect of ceiling height on the response time of rate of rise heat detectors. A 7 m × 5 m simulation model was constructed using the PyroSim program, and scenarios were conducted by varying the installation height from 4.0 m to 7.5 m in 0.5 m increments. A wooden pallet fire source, placed at a height of 1.22 m, was simulated. The simulation results showed that as the installation height increased, the response time was delayed from 155.6 seconds to 204.6 seconds a difference of approximately 49 seconds. Meanwhile, the activation temperature decreased from 50.4 ℃ to 43.4 ℃, representing a drop of about 7 ℃. These findings indicate that in structures with higher ceilings, the responsiveness of detectors may be compromised due to the delayed arrival of hot air flows. Therefore, current height based installation standards in prescriptive design should be re-evaluated for high ceiling structures. Complementary design measures such as optimized placement, detector type selection, and increased installation density are recommended.

The Pyrosim fire simulation program was used to investigate changes in operating time as a function of the attachment height of a fixed-temperature detector. Operating times were analyzed for detector heights ranging from 4 m to 7.5 m, in 0.5 m increments, within a 30 m2 space. The fire source was modeled as a wooden pallet 1.22 m in height, and a Type 1 fixed-temperature detector with an activation temperature of 67.9℃ was used. The simulation results showed that operating time increased progressively with detector height, rising from 155.7 seconds at 4m to 206.3 seconds at 7.5 m a maximum delay of 50.6 seconds. Notably, larger increases were observed in the 4 m ~ 4.5 m and 6 m ~ 6.5 m ranges 14.9 and 11.5 seconds, respectively than those observed in other intervals. This suggests that critical height ranges should be considered when establishing detector installation standards. This study found that current design standards may not ensure adequate detection performance in high-ceilinged structures. In warehouses and industrial facilities with ceilings of 6m or higher, such delays in detector activation could hinder early detection, indicating a need for improvements

This study analyzed the prevalence and determinants of work-related musculoskeletal disorders (WMSDs) using domestic statistical data from 2007 to 2024. Over the past 18 years, the number of WMSD cases approved for industrial accident compensation increased by 110.6%, accounting for 60.3% of all occupational diseases, confirming it is a serious social issue. In this empirical study, we utilized crossanalysis and Pearson's Chi-squared test to examine the relationship between WMSD types and worker characteristics (gender, age) and workplace characteristics (industry, size). The analysis revealed a statistically significant difference in WMSD types based on the worker's gender, age, industry, and workplace size, confirming all hypotheses. Men had a higher proportion of diseases from "tasks imposing excessive physical burden," while women had a higher rate of "carpal tunnel syndrome". The incidence of disorders from physically demanding tasks was also higher with increasing age, in physically intensive sectors like manufacturing, construction, and mining, and in larger workplaces. These findings underscore the critical need for future WMSD prevention policies to be tailored by comprehensively considering both worker characteristics and the specific work environment. The results of this study provide valuable foundational data for establishing targeted and effective occupational health and safety policies, ultimately contributing to the reduction of industrial accidents and improving the well-being of workers.
