The 2019–2020 Black Summer fire season highlighted the vulnerability of water monitoring sites, causing damage, data loss, and negatively affecting water management during massive wildfires. It becomes crucial to reduce the impact of wildfires on them. The current study aims to improve the fire resistance of monitoring equipment. Internal thermal insulation was designed for the instrumentation cabinets and tested under different wildfire conditions to evaluate the performance of various materials and equipment designs. The results demonstrated that the new design of the instrumentation cabinet managed to significantly reduce the effect of thermal exposure and kept the temperatures inside the cabinet below the critical threshold of 70 °C for electronics components. Recommendations of insulation and alternative designs are provided for construction in wildland and wildland-urban interface areas.

The accidental release of a flammable gas on a road can result in a vapour cloud explosion (VCE). Such VCEs generate a blast wave that propagates away from the explosion, potentially damaging nearby structures. The TNO Multi-Energy Method is commonly used for a simplified estimate of the blast load resulting from a VCE. The method characterises the severity and duration of the blast wave using a case-specific strength class and combustion energy (which the method relates to the gas volume of the equivalent blast source). However, no specific guidelines for estimating the strength class in urban roads or related settings (such as carparks) are currently available in the literature. This makes implementing the method in such scenarios challenging and imprecise. The authors’ work used computational fluid dynamics (CFD) to evaluate multiple gas explosion scenarios and proposed recommendations for determining the strength class and gas volume at the blast source. These scenarios comprised a group of vehicles engulfed by a stoichiometric propane-air cloud. It was concluded that the strength class could be reasonably estimated based on the number of vehicles in the transverse direction. Furthermore, the guidance for estimating the gas volume at the equivalent blast source was based on the critical gas volume, after which no further enhancement of overpressure was obtained. The recommendations were implemented in several scenarios and compared with corresponding CFD analyses. The results showed very good agreement for predicting impulse. Predicting overpressure was affected by the inherent asymmetry of the scenarios, although it was possible to achieve acceptable and conservative results.

With the continuous advancement in vehicle intelligence, enhancing safety has emerged as a key priority in intelligent vehicle research and development. Intelligent vehicles are currently limited in supporting autonomous or human-driven modes. This limitation becomes apparent in complex driving scenarios, where vehicle risk response capabilities are inadequate. This paper suggests that shifting from a single decision maker to a human–machine collaboration approach is a potential solution. However, current research on human–machine collaboration in intelligent vehicles primarily focuses on intelligent systems that assist the driver, rather than treating the driver and the system as equals. This approach overlooks the role of the driver in helping the system, lacks effective communication, and diminishes the sense of collaborative cooperation, all of which hinder the promotion of efficient, safe, and stable driving. Inspired by the aviation approach to risk management through Crew Resource Management (CRM), this study introduces the Collaborative Operation Mode (CO-Mode) for intelligent vehicles. Based on CO-Mode’s requirements for human–machine collaborative perception, decision making, and control, the Autonomous Vehicle Collaborative Resource Management (AV-CRM) is proposed. In addition, challenges and future perspectives are explored by analyzing the abilities and limitations of relevant technologies. The proposed AV-CRM redefines the relationship between drivers and intelligent systems, offering new insights into the safety of intelligent vehicles and their technological evolution.

Cyber–physical systems (CPSs) are becoming increasingly complex, integrating physical entities with diverse computing and communication resources, multiple processors, networks, and devices. One example is the Unmanned Aircraft Systems (UAS) Traffic Management (UTM) system, where interactions among components can lead to UAS collisions and harm to people and property. System Theoretic Process Analysis (STPA) is a systems theory-based technique for conducting early-stage safety analyses of complex systems. The Model the Control Structure step in STPA involves identifying each controller component, its process models, and its control actions. However, conventional STPA process models use only variables and states, which may be insufficient for systems involving entities that transition through multiple state flows. This study introduces a novel extension by integrating Finite State Machine (FSM) modeling into the Model the Control Structure step. The FSM-based approach captures detailed behaviors of entities requiring control by explicitly modeling their states and transitions in an iterative process. This extended STPA was applied to the UTM to control the delivery of UAV packages. The results demonstrate that the FSM extension enhances identifying control actions, feedback loops, process model variables, and unsafe control actions. The study concludes that the extended STPA provides a systematic approach for analyzing CPSs with entities that undergo complex state transitions, contributing to improved systematization and consistency of safety analyses.

This study proposes a model integrating YOLOv11 and STGCN for accurate and real-time detection of fall behaviors within buildings. A specialized video dataset comprising fall behaviors performed by six volunteers was developed and used to validate the model’s effectiveness in cloud computing and edge computing environments. The results obtained in the cloud computing environment were characterized by ample computational resources and the absence of real-time constraints. The model achieved precision, recall, and F1-score for fall behaviors exceeding 0.98. The model was integrated into edge computing devices in an actual test environment to directly process real-time video stream data. A missed detection rate of 18 % was observed on the Jetson ORIN NX 16GB device, while the Jetson AGX Orin 64GB recorded a lower missed detection rate of 15 %. Similarly, a false alarm rate of 16 % was observed on the Jetson ORIN NX 16GB device and 12 % on the Jetson AGX Orin 64GB device. These performance differences between the high-performance cloud computing cluster and edge computing devices, as well as among different edge computing devices, may be attributed to variations in computational resources, data quality, and device parameters. The results demonstrate the potential of the proposed model for real-time fall detection in resource-constrained environments.
本研究提出了一个整合YOLOv11和STGCN的模型,用于准确实时地检测建筑物内的坠落行为。开发了包含六名志愿者摔倒行为的专门视频数据集,并用于验证该模型在云计算和边缘计算环境中的有效性。在云计算环境中获得的结果具有计算资源充足和没有实时约束的特点。该模型对跌倒行为的查全率、查全率和f1得分均超过0.98。在实际测试环境中,将该模型集成到边缘计算设备中,直接处理实时视频流数据。Jetson ORIN NX 16GB设备的漏检率为18%,而Jetson AGX ORIN 64GB设备的漏检率较低,为15%。同样,在Jetson ORIN NX 16GB设备上观察到的误报率为16%,在Jetson AGX ORIN 64GB设备上观察到的误报率为12%。高性能云计算集群和边缘计算设备之间以及不同边缘计算设备之间的这些性能差异可能归因于计算资源、数据质量和设备参数的差异。结果证明了该模型在资源受限环境下进行实时跌倒检测的潜力。

Musculoskeletal disorders (MSDs) in the mining sector are frequently associated with exposure to ergonomic risk factors, leading to decreased productivity and increased absenteeism. This study presents a systematic literature review of ergonomic evaluation methods, identified risk factors, and affected body regions, based on journal articles indexed in ScienceDirect, Emerald, Taylor & Francis, Wiley, Scopus, Sage, IEEE Xplore, and Web of Science. From an initial pool of 213 studies, 49 primary studies were selected, 82 % of which were published in Q1 or Q2 journals. The review identifies six individual ergonomic assessment methods (Nordic Questionnaire, ISO/IEC 2631–1, REBA, OWAS, NIOSH, and Risk Score) and two hybrid methods (Bayesian Network + REBA, and RULA + Nordic Questionnaire). Additionally, it categorizes 13 affected body parts (e.g., back, shoulders, neck, waist) and 11 ergonomic factors (e.g., heavy loads, repetitive tasks, vibration, static postures, and work schedules). The findings reveal that a majority of studies focus on underground mining operations, with the Nordic Questionnaire and ISO/IEC 2631–1 being the most frequently used methods. The back and shoulders are the most commonly studied body parts, while vibration and working hours emerge as the most prevalent risk factors. Finally, six challenges are proposed to address current research gaps, including the integration of deep learning techniques and the evaluation of less-studied joints such as the wrist and elbow. This review provides a valuable foundation for researchers and mine safety professionals seeking to advance ergonomic assessment in mining environments.

Facing the global pandemic of coronavirus disease 2019 (COVID-19), countries and regions have implemented different policies and non-pharmacological interventions (NPIs) according to their circumstances. These policies and intervention measures provide new insights into assessing local resilience from the perspective of response capacities in the public health system. This study aims to establish a multi-dimensional and dynamic resilience assessment model based on the index system method. The complete assessment model includes building a comprehensive system, executing the system in specific scenarios, and measuring resilience. The comprehensive system, like a guideline, is constructed from six key categories. The system involves the entire society, encompassing various levels, including country, state, province, city, local community, and individual. It considers not only policy formulation but also the actual implementation of the policy. The comprehensive system does not necessarily apply to all scenarios during the system's implementation. The actual case, the prevention & control in England, is introduced to assess the local resilience and verify the proposed assessment model. The results prove that our model can be used to assess local resilience for the public health system and seek capacity improvement when responding to epidemic situations.

In recent years, with continued urbanization, subway stations with complex structures have developed rapidly, posing serious challenges to daily crowd management and emergency evacuation safety. A social force-based evacuation guidance model was developed to simulate the process of pedestrian evacuation at the concourse level of a subway station in Shenyang by combining questionnaires and field surveys. The objective was to explore the impact of various factors—such as the viewing distance, guidance number, guidance location, and proportion of pedestrians accepting the guiding information—on evacuation efficiency in subway station halls with multiple exits. The results showed that static leaders reduced the evacuation time, especially in situations with a limited field of view. Compared with the “no guidance” case, the evacuation time was shortened by approximately 20.16 % and 9 % when the viewing distances were 2 and 6 m, respectively. Moreover, a small number of static leaders could effectively guide the crowd to evacuate the subway station hall, demonstrating the positive role of guidance in emergency evacuations. Considering the actual situation and human cost, it was reasonable to have eight static leaders in the subway station hall, which reduced the evacuation time by approximately 40.47 % compared to the situation without guidance. Influenced by the viewing distance, scene layout, and pedestrian density, when static leaders were distributed at the exits, evacuation improved. Moreover, the higher the percentage of pedestrians accepting the guidance information, the better the evacuation performance. This study provides scientific support for guidance arrangements in the daily management and emergency evacuation of subway stations.

Working at height is widespread across various industries, with frequent and hazardous falls occurring regularly. Such tasks are often linked to multifactorial issues, where the interplay of diverse factors leads to accidents that are challenging to control effectively. This study establishes an index system for the factors influencing falls from height by statistically analyzing 101 incidents, identifying 64 causative elements classified into four categories. These include 17 factors related to operator condition and behavior, 13 concerning equipment and facility conditions, 7 pertaining to site conditions, and 27 associated with production operations management. Utilizing the Apriori algorithm and Gephi software, the study mined the association rules of causal factors in falls from height and constructed their network diagram. By examining association rules with high support, confidence, and lift, the relationships between key causal factors leading to accidents are clarified, identifying critical operational control points and providing a scientific foundation for reducing the incidence of falls from height. Currently, China's standards related to working at height remain fragmented. This study lays the foundation for the development of comprehensive, systematic, generic safety management standards for working at height, satisfying the needs of the field.

Stone, sand, and gravel mining accounts for 80 % of all mining operations. Maintaining a skilled labor force is essential for this large and growing mining sector. Occupational injuries negatively impact worker health and well-being and are costly. Additionally, injuries may impact workers’ job satisfaction and their desire to seek other employment. The impact of work-related occupational injuries on job satisfaction and turnover intention has not been explored in stone, sand, and gravel mining operations. This study analyzed cross-sectional data from 459 workers employed in the stone, sand, and gravel mining industry in the midwestern United States. Mplus was used to complete path analysis to assess a hypothesized model and its relationships. Analyses determined the model was a good fit for the data, occupational injuries negatively impacted worker job satisfaction, job satisfaction negatively impacted turnover intention, and job satisfaction mediated the relationship between occupational injuries and turnover intention. These findings confirm posited hypotheses and provide evidence that occupational injuries not only harm workers but also result in diminished job satisfaction and ultimately turnover intention, important business outcomes for the stone, sand, and gravel mining industry.
