Background: The aircraft cockpit is a highly intensive human-computer interaction system, and its design directly affects flight safety.
Objective: To optimize the display interface design in complex flight tasks, the present study aimed to propose a dynamic conceptual framework and a timeline task analysis method for the quantization of the dynamic time effect of mental workload and the influencing factors of task types in the mental workload prediction model.
Methods: The multi-factor mental workload prediction model based on attention resource allocation was integrated to establish the dynamic prediction model of mental workload. The ergonomics simulation experiment was carried out by recording the data on the performance of embedded subtasks, National Aeronautics and Space Administration-Task Load Index (NASA-TLX) subjective evaluation, and eye tracking.
Results: The results indicated that the prediction model had a good prediction accuracy and effectiveness under different simulated interfaces and complex tasks, and the real-time monitoring of pilots' mental workload state was realized.
Conclusion: In conclusion, the prediction model and the experimental method could be applied to avoid the overload of the pilot throughout the flight phase by optimizing the display interface and adjusting the flight task.

School principals' proposals for preventive actions to improve mental health.
Arch Public Health
January 2025
Division of Occupational and Environmental Medicine, Lund University, Lund, Sweden.
Background: School principals face a demanding work situation that puts them at risk for stress-related poor mental health. Ideally, preventive actions should be based on knowledge about the underlying notions that motivate action. However, knowledge about prevention areas and suitable initiatives for school principals is scarce or lacking, leaving key stakeholders without the overview necessary for effectively engaging in preventive actions.

Department of Nursing, Kwame Nkrumah University of Science and Technology, Kumasi, Ghana.
Background: The nursing profession plays a crucial role in the quality of healthcare services. While nurses face occupational injury challenges globally, mental workload, which is often overlooked, plays a significant role in these injuries. Understanding nurses' coping strategies can help develop effective interventions.

Background: Driver disengagement in partially automated driving is a serious safety concern. Intermittent conversational prompts that require responses may be a solution.
Background: Critical care nurses are vulnerable to depression, which not only lead to poor well-being and increased turnover intention, but also affect their working performances and organizational productivity as well. Work related factors are important drivers of depressive symptoms. However, the non-liner and multi-directional relationships between job demands-resources and depressive symptoms in critical care nurses has not been adequately analyzed.

BMC Prim Care
January 2025
Faculty of Medine, University of Jordan, Jordan University Hospital, Amman, Jordan.
Background: Musculoskeletal (MSK) conditions, such as back pain and joint disorders, are common globally and significantly burden healthcare systems. Family medicine clinics serve as the first point of care, requiring providers to manage diverse MSK issues and address gender-specific differences, especially in regions with limited resources, like the Middle East. This study evaluates MSK management, gender differences, and patient perceptions in Jordanian family medicine clinics, aiming to improve care strategies and outcomes in similar settings.
