Summary: This study analyzed the posture of oral and maxillofacial surgeons using RULA and found that their working positions put them at high risk for musculoskeletal strain, particularly in the wrists and hands, elbows, lower arms, and neck. The first dental quadrant of their work caused the most unfavorable postures for the surgeons.

Summary: This study investigates the ergonomic risks for dentists and dental assistants in different fields of dental specialization, and compares the risks between dentists and dental assistants within each field. The results show significantly reduced ergonomic risks in endodontology and orthodontics for dental assistants, and in orthodontics for dentists compared to general dentistry. Furthermore, there are specific differences between the fields of specialization.

Summary: Manual material handling in supermarkets may contribute to work-related musculoskeletal disorders, especially in the lower back. The study found that high shoulder forces were associated with lifting heavy merchandise to high shelves, while the weight of handled merchandise was the main predictor of high knee forces. The research addressed limitations of traditional analysis tools and provided a detailed analysis of biomechanical loads in manual material handling tasks in the supermarket sector based on field measurements.

Summary: In this research, real-time motion tracking of kinematic chains is achieved by placing inertial sensors on rotational joints. Reliable motion tracking is ensured by avoiding the use of magnetometer measurements. The observability of the relative pose of body segments is formally analyzed and validated through simulation studies and experimental data.

Summary: The validity of the 4D Motion IMU system for analyzing baseball pitching motion compared to marker-based motion capture was evaluated. Significant differences were found between the two methods, with the IMU system lacking internal consistency and reliability. Caution should be exercised when using metrics provided by an IMU-based system for individualized monitoring.

Summary: The authors demonstrate a topographic design for wearable MXene sensor modules with wireless streaming or in-sensor computing models for avatar reconstruction. The wearable strain sensor modules exhibited ultrahigh sensitivities within the working windows that meet all joint deformation ranges. By integrating the wearable sensors with a ML chip, an edge sensor module is fabricated, enabling in-sensor reconstruction of high-precision avatar animations.

Summary: This study investigated the measures for dealing with violence in emergency care and employees' subjective evaluations. The results showed that the availability of security staff and standardized reporting of incidents were considered important measures, but they were not consistently implemented. High workload in emergency care may impede the implementation of measures, and there is a clear demand for increased support from supervisors and hospital management.

Summary: This study aims to explore the perceptions of ED staff on available violence prevention measures and their effectiveness. Participants reported the effectiveness of environmental, organisational, and individual-focused measures, but financial constraints were identified as the main barrier for implementation. To address this, reducing workload, developing tailored guidelines, and implementing screening tools are recommended. Hospitals should provide guidelines to ED staff, and prevention measures need to be practiced and communicated.

Summary: The aim of this study was to analyze the influence of different music genres, modulated noises and pink noise on heart rate, and to compare the effects among young healthy adults, elderly healthy adults, and patients with Parkinson's disease. The results showed that younger people have a higher variability in heart rate, indicating that they are more sensitive to the conditions studied. The findings suggest that listening to music does not have a systematic influence on decreasing or increasing heart rate.

Summary: The study aimed to investigate work-related musculoskeletal disorders among dance teachers in Germany. A survey was conducted with 229 dance teachers, revealing a 12-month prevalence rate of 60.7%. The most affected areas were the lumbar spine and ankle, and no significant differences were found based on dance styles and gender. These findings are important for developing prevention strategies and personalized interventions.

Summary: Due to irregular working hours and additional family responsibilities, nursing staff may experience disturbances in their internal clock and have a higher risk of daytime sleepiness compared to other occupational groups who do not work in shifts. Female nurses are particularly at risk and have a statistically significant increased risk of excessive daytime sleepiness compared to men from other occupational sectors.

Summary: This systematic review examined the relationship between aggressive and chronic periodontitis and orthodontic treatment. The results showed that orthodontic treatment can improve function and esthetics in periodontally compromised patients, resulting in lower probing depths and clinical attachment gains. However, more high-quality studies are needed to obtain reliable and reproducible treatment results.
