In order to optimize the community emergency supplies reserve, the concept of BCM was introduced to study the multi-objective optimization model of community emergency supplies reserve. Firstly, the key services and related emergency supplies after the disaster were identified, and the community emergency support capacity was quantified by constructing the post-disaster living standard change curve. Secondly, a multi-objective optimization model for material reserves with the maximum guarantee capacity and the minimum cost is proposed. Finally, the numerical examples were solved and the sensitivity analysis of the key parameters was carried out. The results indicate that as the minimum business continuity objective increases, the level of emergency material reserves increases, enhancing the community emergency support capacity. The reserves show a priority order, with lower-cost items being increased first. Under the same level of emergency material reserves, enhancing community emergency response and handling capabilities can improve the community emergency support capacity. Moreover, as the reserves of emergency materials in a community grow, the significance of these capacities in improving the emergency support capacity becomes increasingly pronounced. The emergency material reserve optimization model constructed from the perspective of business continuity can enable the community to provide basic living guarantees for residents after emergencies.

In order to solve the problem of low guidance efficiency of emergency evacuation signs, a layout optimization method of emergency evacuation signs considering pedestrian perceptual behavior was proposed. Firstly, the recognizable range and probability distribution of the signs were investigated to establish a model of pedestrians' perceptual behavior towards the signs; secondly, a layout optimization model was constructed considering the number, location and orientation of the signs by combining it with the distribution of the guidance demand in the multi-exit space; finally, a case study of a cruise ship was used, where a genetic algorithm is applied to solve the problem. The evacuation efficiency, both before and after the optimization of the signage layout, was evaluated through microscopic crowd evacuation simulation, respectively. The results show that the average evacuation time under the optimized layout is 10.3% shorter than that under the unoptimized layout when the pedestrians are randomly distributed at the initial position; the average evacuation time is 4.2% shorter under the scenario simulating the actual evacuation process, and the number of pedestrians guided to different destinations is more balanced.

The human body is susceptible to heat diseases when exposed to high temperature and high humidity for a long period of time. In order to assess the level of human heat stress in indoor high temperature and high humidity environments, the paper utilized the EWM to determine the weights of measurement parameters such as Mean Skin Temperature (MST), Heart Rate (HR), Oral Temperature (OT) and Tympanic Temperature (TT). A new comprehensive evaluation index QI was established based on VIKOR model. The reasonableness of QI was validated by fitting with the subjective parameters and the environmental parameters. The grading of QI was determined by improving the thermal stress intensity grading of the physiological stress indicator PHSI. The results show that the weight ranges of TT, MST, OT and HR are 0.151 9-0.421 1, 0.193 5-0.345 2, 0.160 4-0.426 9 and 0.134 8-0.339 1, respectively. MST has a high mean value of weight, which is greatly affected by environmental factors and labor factors. QI's safety range [0,0.36), thermal tolerance range [0.36,0.57] and hazardous range (0.57,1].

In order to provide a comprehensive overview of the current state of research and knowledge evolution in the field of occupational hazard factors and health risks associated with building decoration, a systematic review of the relevant literature was conducted using the China National Knowledge Infrastructure (CNKI) database and the Web of Science (WoS) core database. Visualisation tools were employed to make knowledge maps of the spatial and temporal distribution, research hotspots and research frontiers of the identified literature. The results show the number of published articles in both Chinese and English increased significantly since 2003. The relevant research is influenced by economic conditions, the real estate market, and the level of emphasis placed on health by both national and international communities. The extant literature can be broadly classified into three categories: workplace environment, occupational hazard factors and health risks. Studies have been conducted throughout the entire period pertaining to indoor air pollution, indoor air quality, detrimental factors and formaldehyde. The research field continues to yield new insights and deepen its understanding. However, there remain areas that require further investigation with regard to the occupational health of workers. In the future, the studies could focus on the occupational health problems caused by different types of decoration, with a particular emphasis on the pollution characteristics of new pollutants and the occupational health risks and protection of workers.

In order to study the SFEP and its characteristics, a method for describing SFEP using quantum concepts is proposed. The relationship between SFEP and event function states was discussed. The principle of describing SFEP by quantum thought was studied. The mathematical model of quantum description of SFEP was constructed. The measurement collapse of SFEP quantum states was realized, and the failure mode and its probability were finally determined. The results indicate that SFEP has diversity and uncertainty, event quantum state superposition, measurement collapse, bipolar state, which is the basis of studying SFEP through quantum thought. SFEP can be decomposed into multiple layers, with distinct objects and quantum state superposition modes in each layer. The SFEP quantum states are derived from the superposition of the quantum states of objects at each layer, which is composed of the polynomial product of the probability amplitude of the objects in each layer. The restriction conditions for the formation of the probability amplitude of quantum states of each layer are given. Each dimension of the SFEP quantum state vector is a fault state. The measurement of the factor phase value makes the SFEP quantum state collapse, and the possible failure mode and occurrence probability are obtained.

In order to reduce the incidence of unsafe behaviors and strengthen the effect of unsafe behaviors popularization, a novel golden monkey metaphor was constructed based on the conceptual integration theory. Taking the severity information and the metaphorical framework of unsafe behaviors as independent variables, the experimental process of the unsafe behaviors metaphor was designed to explore the influence mechanism and possible intermediary factors of golden monkey metaphor on unsafe behavior. The results show that golden monkey is a human-subjective, pervasive, and high-frequency unsafe behavior that results in relatively small transient losses. Low severity messages increase willingness to change behavior. The use of golden monkey metaphors to imply unsafe behaviors is more persuasive than nonmetaphors and increases willingness to change behavior. Severity and negative emotions play a suppression effect and a fully mediating effect between severity message and willingness to change behavior respectively, and degree of cognitive fine processing partially mediates the effect between metaphorical framing of unsafe behavior and willingness to change behavior.

In order to improve the work safety management level of China's chemical (hazardous chemicals) industry, firstly, the formation of chemical process safety management was expounded, including the traditional management method and the proposal of process safety concept. Then, the characteristics and specific content of the elements of the chemical process management elements system in China were analyzed, including 8 modules and 20 elements. Finally, a systematic solution was proposed, that was, four-element solution with safety leadership, management barrier (responsibility, equipment, management and capability), and safety culture as the primary-level elements. The results show that core elements of four-element solution are the concept, safety leadership, management barrier (responsibility, equipment, management, capability) and safety culture. Among them, safety leadership is the most critical element, leading the concept into practice, responsibility division, equipment upgrading, management system construction, capability improvement and culture cultivation. Other elements together constitute the skeleton of work safety management, and realize systematization. Businesses can help prevent accidents and improve the overall safety level of the industry by taking the lead and promoting the implementation of various elements through participation of all staff.

In addressing the issues of non-compliance by ground service agents and lax supervision by airlines in the transportation of hazardous materials in civil aviation. Firstly, evolutionary game models between airlines and ground service agents were constructed under both static and dynamic punishment mechanisms. The evolutionary stable strategies under different mechanisms were then explored. Subsequently, a quantitative analysis model was developed by integrating system dynamics to further analyze the interactions between the two parties. Finally, simulations were conducted to analyze the impact of key parameters on the behavioral strategies of both sides. The results reveal that under the static punishment mechanism, no stable equilibrium point is observed in the game system. No evolutionary stable strategy is formed, with the behavioral strategies of both parties showing periodic fluctuations over time. In contrast, when a dynamic punishment mechanism is introduced, a stable equilibrium point emerged in the game system. The behavioral strategies of both parties converge to a stable focal point. Moreover, compared with a low level of punishment, a higher level of punishment is found to be more effective in increasing the probability that ground service agents strictly comply with the agency agreement.

In order to explore the interaction mechanism among various behaviors in coal mine safety management, firstly, the coal mine safety management behaviors were divided into organizational safety behavior and individual unsafe behavior. Then, four dimensions and 16 sub-dimensions of organizational safety behaviors were identified, and 11 types of unsafe behavior were also identified. Finally, the interrelationships of different dimensions of organizational safety behaviors were explored, and the interaction model of coal mine safety management behavior was constructed. The results indicate that the highest degree of cause is safety supervision and inspection, and the lowest degree of cause is safety accident management. Safety education and training plays an important role as an intermediary and a bridge. The higher centrality of implementing training programs and providing adequate and effective safety training indicates that they dominate the interactions of organizational safety behaviors. The most common unsafe behavior is the failure to effectively stop and correct violations. The interaction model of coal mine safety management behavior includes a driving mechanism and a feedback mechanism.

In order to investigate the variation characteristics of flue-gas temperature at different locations of flame retardant belt during a fire, a fire test was conducted on flame-retardant conveyor belts in a full-scale roadway. First, six temperature measurement sections were arranged along the axial direction in the roadway, and five thermocouples were installed at each section to record the flue-gas temperature at different locations during the combustion process. Then, a fire characteristic test was conducted on a 4 m × 1.2 m (length × width) steel wire rope core flame retardant belt under the condition of wind speed of 1.2 m/s in the full-scale roadway. The experimental results show that the distance from the fire source determines the flue-gas temperature and temperature rise process in the downstream area of the fire source. The closer to the fire source, the stronger the heat effect caused by the combustion of flame retardant tape, and the higher the flue-gas temperature at the corresponding location. Since the tape fire is an unsteady combustion process, and the change in smoke temperature at different sections after a period of time is nonlinear related to the distance from the fire source. In a horizontal roadway at the same height, the flue-gas temperature on both sides of the roadway is higher than that in the middle of the roadway. As the distance from the fire source increases, the temperature difference between the middle and the sides of the roadway gradually decreases. In the longitudinal range of the roadway downstream of the fire source, the flue-gas exhibits a stratified state, and the flue-gas temperature decreases gradually from the roof to the floor of the roadway. There is an obvious temperature difference between flue-gas layers at different heights, and the temperature difference between the flue-gas layers decreases gradually with increasing distance from the fire source.
