Background: Studies have extensively examined the factors contributing to the onset of occupational stress, burnout, and depression. However, the relationship between these variables is limited.

Objective: This study aimed to explore the association between occupational stress, burnout, and depressive symptoms and to investigate the mediating effect of burnout between occupational stress and depressive symptoms in medical staff.

Methods: A cross-sectional survey was conducted among medical staff in Chongqing, China. The Core Occupational Stress Scale (COSS), Maslach Burnout Inventory: General Survey (MBI-GS), and Patient Health Questionnaire-9 (PHQ-9) were used to assess the status of occupational stress, burnout, and depressive symptoms, respectively. The bootstrapping analyses using SPSS PROCESS macros version 3 were conducted to examine mediating effects.

Results: The study conducted on medical staff in Chongqing revealed that the detection rates of occupational stress, occupational burnout, and depressive symptoms were 31.8%, 23.3%, and 30.3%, respectively. Hierarchical regression analysis revealed that occupational stress and burnout accounted for 19.3% (p < 0.001) and 18.8% (p < 0.001) of the variance in depressive symptoms, respectively. Mediation analysis showed that occupational stress indirectly affected depressive symptoms through the mediating effect of occupational burnout, with a mediation effect value of 0.13 (bootstrap 95% CI: 0.116-0.144) and the mediation effect accounting for 44.8% of the total effect.

Conclusion: Our results indicated that occupational stress and burnout were predictors of depressive symptoms. Occupational stress had a significant indirect effect on depressive symptoms via burnout. These results suggest that reducing occupational stress and burnout could be effective strategies for preventing depression among medical staff.

Background: Despite the societal importance to improve understanding of the role of employers in the inclusion of workers with a distance to the labor market, scant knowledge is available on the effectiveness of human resource management (HRM) bundles for the inclusion of vulnerable workers.

Objective: This paper studies which HRM bundles are applied by employers that hired people with a distance to the labor market, and to what extent these different bundles of HRM practices are related to employment of workers with specific vulnerabilities, such as people with disabilities or people with a migration background.

Methods: A latent class analysis of 1,665 inclusive employers was used to identify HRM bundles based on seven HRM practices: financial support practices, specialized recruitment, promotion and career opportunities, training opportunities, part-time work, job crafting, and adaptations to the workplace.

Results: Six bundles were identified: a recruitment and development bundle (34.4% of employers), a development bundle (24.8%), maintenance-focused practices (16.5%), a recruitment bundle (9.4%), a sustainable employment bundle (8.9%), and passive HRM (6.0%). Post-hoc analyses showed the probability of hiring specific vulnerable groups for each bundle (e.g., sustainable employment bundles showed the highest overall probability to hire people with a physical disability).

Conclusion: Nuancing what is suggested in strategic HRM literature, we conclude that both extensive HRM and focused HRM bundles can be successful for the employment of vulnerable workers. In conclusion, there is no one-size-fits-all approach to inclusive employment and employers, large or small, can tailor their HRM systems to include vulnerable workers.

Background: Educational environments can have environmental conditions that are incompatible with the needs of students, compromising their well-being and affecting their performance.

Objective: To identify the environmental variables that influence the performance of university students and measure this influence through an experiment in indoor environments.

Methods: The study applied an experimental methodology for three consecutive days in seven educational environments located in different regions of Brazil, measuring the environ-mental conditions, the students' perception of the environment, and their cognitive performance. The impact of environmental variables and environmental perception on student performance was analyzed using Generalized Linear Models and a Structural Equation Model.

Results: Students who took the test at air temperatures between 22.4°C and 24.7°C had a 74.20% chance of performing better than those outside this range. Air temperatures between 26.2°C and 29°C were associated with an 86% chance of taking less time to complete the test. High illuminance levels increased the chance of taking longer to answer the test by 41.7%.

Conclusions: Three environmental variables (relative humidity, lighting and air temperature) and two perceptual dimensions (light and thermal perception) directly influence student performance.

Background: During the COVID-19 pandemic, the mental health of healthcare professionals has emerged as an issue of great concern.

Objective: To investigate the levels of professional quality of life, psychological well-being, and work engagement among healthcare professionals in two Greek hospitals during the COVID-19 pandemic.

Methods: A cross-sectional study was conducted in December 2021 in two public hospitals in Greece. To assess the levels of professional quality of life, psychological well-being, and work engagement, respondents completed the Professional Quality of Life Scale Version 5 (ProQOL-V), the Psychological Well-being (PWB) scale, and the Utrecht Work Engagement Scale (UWES-17).

Results: A total of 150 questionnaires were distributed, and 102 were returned (response rate: 68%). It was found that as burnout levels increased, the levels of work engagement decreased (rho = -0.36, p-value < 0.01). Higher levels of compassion satisfaction were associated with higher work engagement (rho = 0.48, p-value < 0.01). Multivariable analysis revealed that healthcare personnel's contact with patients or service users exposed to or who have experienced traumatic events was associated with less positive relationships with others (and, consequently, lower levels of psychological well-being) (p-value = 0.035).

Conclusions: Healthcare professionals in the two public hospitals in Greece, experienced moderate levels of compassion satisfaction, burnout, and secondary traumatic stress during the COVID-19 pandemic. Their psychological well-being was also found to be moderate, and their levels of work engagement were moderate to high. Supporting the physical and psychological well-being of healthcare professionals is essential for their ability to provide high-quality care in times of crisis, such as during the COVID-19 pandemic.

Background: An underground workplace (UGW) is a complex system with multiple subsystems that interact with each other. However, the research on UGW from a systemic perspective has not received due attention.

Objective: This study constructs an evaluation approach to the orderliness of UGW and systematically evaluates the UGW with Guangzhou and Chengdu metro depots as case studies.

Methods: First, the evaluation index system is established based on occupational ergonomics. Second, the system entropy model is constructed based on information entropy. Third, a dissipative structure judgment model is built based on the Brusselator. Fourth, the orderliness evaluation model is constructed based on information entropy and synergetics.

Results: The UGW of the metro depot has not yet reached the dissipative structure and is in a medium-order state. But the system is in the trend of orderly development. The entropy increase caused by the physical environment and health status is the main obstacle for the system to move toward order. The equipment configuration is an essential source of system negative entropy. The coordination between equipment configuration, health status, and physical environment is low, and that of work effectiveness, equipment aging and failure, and organizational environment is high.

Conclusions: Equipment configuration cannot fully cope with the harsh physical environment and meet the needs of underground workers. Safety security equipment has more room for improvement. Humanized support facilities can introduce more negative entropy to the system. Organizational intervention can reduce the negative impact of adverse factors on the system.

Background: During the COVID-19 pandemic, digital working methods were increasingly implemented within the setting of German public administrations. Beyond the ostensible risk of infection, a high psychological burden arose for the employees.

Objective: A subsequent progression of mental strain is to be estimated as a residual effect (approximated by controlling other influencing factors) due to the impossibility of a counterfactual control group.

Methods: An online survey was conducted in 2020 and repeated in 2021 among a cohort of n = 706 employees of 38 departments of three public administrations in North Rhine-Westphalia, Germany. Mental strain was assessed by the Wuppertal Screening Instrument. Its temporal variation was operationalized as the intercept of a first-difference multiple regression model. Unit of analysis was the department level.

Results: The prevalence of suboptimal and dysfunctional strain increased from 71% to 73%. The multiple regression model showed a significant increase whilst controlling the influence of socio-demographic changes on the department level. Children, age and educational level were significant predictors. R2 indicated that about 40% of the variance in the temporal variation of mental strain could be explained.

Conclusion: The observed factors explained a significant proportion of the increase in mental strain in German public administrations. Still, far more than half of the increase stemmed from external influences which were largely determined by pandemic conditions and latency effects remain still to be seen.

Background: Climate change and global warming are emerging as new challenges worldwide. The World Meteorological Organization has reported that the temperature is expected to rise by an average of 1.2°C between 2021-2025. This increase in temperature will expose more and more workers to extreme heat.

Objective: This study aimed to explore the possibility of using thermoelectric coolers for cooling the water circulation circuit of a cooling belt, which can be used for extended periods in high-temperature environments.

Methods: A cooling belt was designed using thermoelectric coolers (TEC) and two blowers. The TECs were equipped with heat sinks and heat exchange block made of aluminum at hot and cold sides to exchange heat effectively.

Results: The experiment was conducted under actual environmental temperature conditions during three different time periods, with mean temperatures of 31, 48, and 41°C. The mean temperature of the belt section was recorded as 20.73, 24.52, and 21.38°C, respectively. The maximum average difference between the inlet air temperature and the inside cooling belt temperature was 40.45°C.

Conclusion: The experiment revealed that the cooling performance of the designed prototype remained within an acceptable range (18°C) despite the increase in ambient temperature. Moreover, the cooling system can be utilized in high-heat environments to reduce thermal stress.

Background: While effective apprehensions of non-compliant suspects are central to public safety, the minimal force needed to transition a suspect from standing to the ground, vital for apprehension success, has not been established.

Objective: To examine the technical-tactical behaviors of general duty police officers during simulated apprehensions and quantify the minimum force required to destabilize non-compliant suspects.

Methods: Task simulations conducted with 91 officers were analyzed to identify common grappling movements, strikes, control tactics, and changes in body posture. A separate assessment of 55 male officers aimed to determine the minimum force required for destabilization in five body regions (wrist, forearm, shoulder, mid-chest, and mid-back). Data are presented as mean±standard deviation.

Results: On average, apprehensions took 7.3±3.2 seconds. While all officers used grappling movements (100%) and the majority employed control tactics (75%), strikes were seldom used (4%). Apprehensions typically began with a two-handed pull (97%; Contact Phase), 55% then attempted an arm bar takedown, followed by a two-handed cross-body pull (68%; Transition/Control Phase), and a two-handed push to the ground (19%; Ground Phase). All officers began in the upright posture, with most shifting to squat (75%), kneel (58%), or bent (45%) postures to complete the apprehension. The minimum force required to disrupt balance differed across body regions (wrist: 54±12 kg; forearm: 49±12 kg; shoulder: 42±10 kg; mid-chest: 44±11 kg; mid-back: 30±7 kg, all P < 0.05), except between the shoulder and chest (P = 0.19).

Conclusion: These findings provide insights that can enhance the design and accuracy of future apprehension evaluations and inform the optimization of law enforcement physical employment standards.

Background: Occupational therapists (OT) assess and prescribe assistive devices to older adults with limitations in performing daily living activities. Timely prescription of assistive devices to accommodate the rising demand has been affected by the COVID-19 pandemic. Tele-assessment allows for continuity of care, but its success depends on therapists' acceptance.

Objective: This study examined OTs' perceptions of the feasibility of conducting tele-assessment and developing a clinical practice guideline for remote prescription of assistive devices for older adults in Singapore.

Methods: Eligible OTs were recruited from purposive sampling. Semi-structured interviews were conducted via a virtual platform (Zoom). Audio recordings were transcribed verbatim. Inductive thematic analysis using a line-by-line coding method was used to identify common trends.

Results: Interviews with 10 participants revealed three main themes: (1) therapists' perceptions of the feasibility of tele-assessment, (2) criteria for safe and appropriate prescription of assistive devices via tele-assessment, and (3) practical considerations for the implementation of tele-assessment. Participants felt that tele-assessment increases efficiency with more older adults being more receptive towards technology. They also raised suggestions to address OTs' concerns regarding the safety and accuracy prescription of assistive devices following tele-assessment. This included establishing the client's suitability for assistive device prescription, characteristics of assistive devices, resources required, and considering the preferences of stakeholders involved.

Conclusion: Tele-assessment for assistive device prescription by OTs appears feasible in Singapore. OTs should consider collaborating with other stakeholders to develop a tele-assessment clinical practice guideline for assistive device prescription. Further studies testing its clinical effectiveness during and/or post-pandemic are warranted.

Background: Few ergonomics studies have explored the work required to implement territorialized public policies.

Objective: To identify key challenges for ergonomists who analyse and support intermediation work taking place in the design and implementation of a Territorial Food Project or TFP (a public policy device).

Methods: We adapted a framework developed in the field of political sociology. The analysis focuses on two scales to identify key characteristics of intermediation work: the agri-urban area as delimited and targeted by the TFP; and the farm and its relationships to food systems. To capture how intermediation work articulates prescription and action, we studied first the work carried out by the actors to use a public policy device such as TFP, and second the evolving farming work systems' connections to food systems and how they are supported by various actors.

Results: Intermediation work is spread across a wide diversity of actors. Coordination at governance level aims to allocate resources among institutional actors and to check the progress of the elaborated action plan. Coordination at operational level, which is meant to support farming work system dynamics or to implement the action plan, focuses on fostering the emergence of initiatives but seems to lack a shared vision and time availability.

Conclusion: We identify two main challenges: to further develop a framework for analysing the intermediation work occurring in a multi-scale and territorial perspective; and to develop new intervention methods so that ergonomists can take part in and support such intermediation work.
