Abstract: BACKGROUND: Accurate assessment tools for work rehabilitation are essential in healthcare settings. Adapting the Work Rehabilitation Questionnaire (WORQ) to Arabic-speaking populations ensures effective evaluation and intervention for individuals with work-related disabilities. OBJECTIVE: To execute a cross-cultural adaptation of interview-administered version Work Rehabilitation Questionnaire –Arabic (WORQ-A) and assess the psychometric properties of WORQ-A in patients with musculoskeletal problems. METHODS: WORQ is mainly intended to assess the work functioning of persons who are involved in vocational rehabilitation. Psychometric properties were scrutinized in the outpatient rehabilitation center. Test–retest reliability was examined with intraclass correlation coefficient (ICC), …and internal consistency was evaluated with Cronbach’s alpha. The usability of WORQ-A was established in 46 patients with musculoskeletal problems. RESULTS: WORQ-A exhibited exceptional internal consistency (0.93) and a great test–retest reliability (0.87). Regarding usability, the ability to understand the questions and answer choices was established as good. Five percent of the participants encountered minor difficulties with certain words, while the majority found it quite straightforward to choose the correct answers. CONCLUSIONS: The WORQ-A is an effective, consistent, and very easy to administer questionnaire to assess the work-related functions assumed in our study context and the individualities of the sample.

Abstract: BACKGROUND: It is extremely important for nursing students to be professionally motivated to train qualified future professional nurses. Students’ vocational motivation is affected by their experiences in clinical and academic learning environments. OBJECTIVE: The aim of this study was to investigate the correlation between the vocational motivation levels of nursing students and their attitudes toward clinical practice. METHODS: 292 nursing students participated in the cross-sectional, descriptive study. The Student Information Form, Nursing Students’ Attitudes Towards Clinical Practices Scale, Motivation Sources and Problems Scale (MSPS) were used to gather the data. RESULTS: …The average score for students’ attitudes toward clinical practice was 107.08±18.13, while the total score for MSPS stood at 3.80±0.63. A positive correlation was identified between the attitude toward clinical practice and vocational motivation levels (r  = 0.367; p  < 0.001). There were positive correlations between the intrinsic motivation (r  = 0.572; p  < 0.001) and extrinsic motivation (r  = 0.58; p  < 0.001), and negative correlations were observed between the negative motivation (r  = -0.324; p  < 0.001) and the attitude toward clinical practice scale. There were positive correlations between belief and expectation (r  = 0.492; p  < 0.001) and positive approach (r  = 0.532; p  < 0.001) with the MSPS. In the multiple regression analysis, intrinsic motivation, extrinsic motivation, satisfaction with studying nursing, and participation in vocational courses were determined as effective predictors of attitudes towards clinical practice and explained 60.4% of the variance. CONCLUSIONS: The study concluded that nursing students’ attitudes toward clinical practices affect vocational motivation. Clinical learning environments should be arranged in a way to increase the motivation level of students towards professional learning. Show more

Abstract: BACKGROUND: Work-related shoulder disorders adversely affect the quality of life and lead to increased costs related to decreased productivity and injury treatment. Therefore, understanding the relationship between strength, upper extremity function and work ability contributes to the development of interventions aimed to improve the well-being of healthcare workers. OBJECTIVE: Correlate shoulder abduction and handgrip strength with upper extremity function and work ability in healthcare workers with shoulder complaints. METHODS: 67 workers with shoulder pain in the last year were assessed by Disability of Arm, Shoulder and Hand (QuickDASH), Work Ability Index (WAI), isokinetic shoulder …strength and isometric handgrip strength dynamometers. Data were analysed with Spearman’s Correlation Coefficient (ρ = 0.05), SPSS 20.0® . RESULTS: 52% males, mean age 48.4 years, 42% physically active, most administrative and general services workers. Low correlation between handgrip strength and QuickDASH (r =-0.359; p  = 0.004); low correlation between handgrip strength and WAI (r  = 0.359; p  = 0.003) and between shoulder abduction strength and the QuickDASH (r  = -0.267; p  = 0.049); no significant correlation between shoulder abduction strength and WAI (r  = 0.001; p  = 0.997). CONCLUSIONS: Handgrip and shoulder abduction strength were inversely associated with upper extremity dysfunction. Shoulder abduction strength was associated with work ability. The inclusion of strength assessment in workers is important to guide strategies to prevent musculoskeletal disorders. Show more

Abstract: BACKGROUND: Quantitatively analyzing the impact of UV radiation and noise during welding operations is essential to assess the exposure, identify potential hazards, and develop targeted safety protocols to ensure worker safety and adherence to safety regulations, especially in developing countries with inadequate adherence to safety standards and resources. OBJECTIVES: This study employs machine learning for predicting ultraviolet radiation and noise levels during welding, emphasizing worker safety. The focus is on the Indian foundry sector to gauge actual exposure vis-á-vis safety standards. MATERIALS AND METHODS: Ultraviolet radiation and noise emitted during the welding of …a ferrous alloy were collected from three foundries in Agra, India. Five machine learning (ML) algorithms were applied for data analysis and prediction of UV radiation and noise levels, and a relative performance comparison was carried out on the compiled data against safety standards. RESULTS: Out of all the ML algorithms applied, the Support Vector Machine regression algorithm (RMSE = 356.93) obtained the best performance on UV radiation data, and the Random Forest algorithm (RMSE = 11.4) was found to give the best results for the noise level prediction task. CONCLUSIONS: This work represents the first known application of machine learning techniques for predicting UV radiation and noise levels in arc welding processes. The results show the efficacy of algorithms such as SVM regression and Random Forest for the problem. Further, the datasets and ML algorithms implemented in the work will be made openly available to support further research endeavors in this and related areas. Show more

Abstract: BACKGROUND: Hajj is a series of rituals that are done in specific areas and periods in Mecca. Performing Hajj requires a great amount of physical demand which may result in musculoskeletal pain (MSP) in different age groups. OBJECTIVE: To estimate the prevalence of MSP and understand its pattern via exploring the factors that could be associated with muscular pain among pilgrims in the 2022 Hajj. METHODS: A web-based survey was distributed during the annual Hajj mass gathering. Pilgrims were recruited from Hajj ritual sites. The collected data included demographics, musculoskeletal …pain at ten anatomical body sites, and physical activity (PA) level. Descriptive and inferential statistics were used to analyze the data at a 0.05 significance level. RESULTS: A total of 248 pilgrims participated in the study. The mean age of the sample was 43.49±12.70 years. Of all pilgrims, 78.6% had reported MSP in at least one anatomical body site during performing Hajj. Results revealed that Pilgrims were more likely to have MSP in the lower limb while performing Hajj rituals where the most prevalent reported pain was in the legs (46%), followed by the lower back (45%), knees (37%), and ankles/feet (30%). Age, sex, and PA were not significantly associated with MSP except the BMI was found to be a significant factor related to MSP among pilgrims (p <0.05). CONCLUSION: Many pilgrims exhibited pain in at least one body part. Although physical fitness recommendations are published in the Saudi Ministry of Health, MSP preventative measures need to be disseminated by organizations and interested parties worldwide.

Abstract: BACKGROUND: Recent research indicates that as men age, their tendency to ruminate about work decreases, while ruminating remains high in women, which poses an increased risk for impaired health among older women. OBJECTIVE: This study explored gender differences/similarities in the process of unwinding from work in men and women aged between 56–65 years. METHODS: Semi-structured qualitative interviews were conducted online with eight men and eight women, recruited from a UK leading organization that provides health care solutions between May and June 2022. Participants were asked about their job role and responsibilities, their leisure …time activities, how they unwind post work, and their experiences of thinking about work related thoughts outside of work. Transcripts were analyzed using an inductive analysis. RESULTS: Three superordinate themes were identified that underpinned their ability to unwind: ‘Work style’, ‘Creating work-life balance’ and ‘Switching off from one’s responsibilities’. Women reported a more perfectionist approach, they set high standards for themselves, were worried about making mistakes, and demonstrated, if in a supervisory role, a more nurturing and holistic approach to their colleagues/subordinates, while men, were more focused on task completion. Most women, but not men, also described difficulties in psychologically switching off from work, and stated they could only truly relax outside the home, when they are away from household activities. CONCLUSION: The study provides nuanced insights into the experiences of unwinding from work, and the findings suggest the need for person-centric approaches in developing interventions to help workers over 56 years to psychologically disengage from work.

Abstract: BACKGROUND: Presenteeism-induced productivity loss is a global concern. This issue is equally serious in Japan. As a “super-aged society,” maintaining and promoting Japanese employees’ health is an urgent issue. The combination of these factors makes it imperative to identify the factors that affect presenteeism and clarify the mechanisms driving these factors in Japanese organizations. OBJECTIVE: Only a few extant studies address presenteeism as a performance variable. Presenteeism can create serious productivity losses in Japan, as it is a “super-aged society.” Hence, this study aims to clarify the relationships between humble leadership, psychological safety, and presenteeism …in Japanese organizations. METHODS: We hypothesized that psychological safety mediated the effect of humble leadership on presenteeism. The data of 462 employees from 11 companies were analyzed. RESULTS: The results supported our hypothesis. Additionally, leader humility, as perceived by the followers, was positively correlated with leaders’ own psychological safety in their teams. CONCLUSIONS: Our findings contribute to the existing literature by highlighting the roles of humble leadership and psychological safety in health and productivity management while accounting for cultural influences. The practical implications of our findings and future directions are also discussed. Show more

Abstract: BACKGROUND: While absenteeism refers to not attending work, presenteeism is defined as not being present at work. These two conditions, which negatively affect employee health, can be indicators of work efficiency, work peace, work safety and work engagement. OBJECTIVE: Several factors were evaluated in this study concerning absenteeism and presenteeism among factory workers. METHODS: This cross-sectional study was conducted among workers in a factory operating in a heavy industry in southern Turkey in 2021. A survey consisting of 57 questions was applied to 152 factory workers by face-to-face interview method. The participants’ behaviour over the last …month was evaluated regarding absenteeism and presenteeism. RESULTS: It was reported that 24 (15.8%) of all employees were absent from work in the last month (absenteeism), excluding holidays and sick leave, and that 20 (13.2%) employees engaged in presenteeism, working when they should not have been at the workplace. There was a high absenteeism rate among employees who had an acute illness and were dissatisfied with their jobs. Several factors have been associated with presenteeism, including poor economic conditions, family health problems, previous unemployment, working overtime, job dissatisfaction, poor relationships with colleagues and difficulty finding a replacement, acute illness, sleep problems and fatigue. CONCLUSIONS: To increase the productivity and commitment of employees, it may be useful to identify the reasons for absenteeism and present behaviours, to facilitate effective interpersonal communication skills by examining the organisational climate of employees, and to regulate workload based on a comprehensive assessment of the health status of employees.

Abstract: BACKGROUND: Work-related musculoskeletal disorders (WMSDs) located in the low back and neck/shoulder regions are major concerns for both workers, workplaces, and society. Masons are prone to WMSD, because their work is characterized by repetitive work and high physical workload. However, the knowledge on the physical workload during bricklaying is primarily based on subjective measurements. OBJECTIVE: This cross-sectional field study with technical measurements aimed to quantify physical workload in terms of muscular activity and degree of forward bending during bricklaying at different working heights among masons, i.e., knee, hip, shoulder, and above shoulder height. METHODS: …Twelve male (36.1±16.1 years) experienced masons participated in a cross-sectional field study with technical measurements. Surface electromyography from erector spinae longissimus and upper trapezius muscles and an inertial measurement unit-sensor placed on the upper back were used to assess the physical workload (level of muscle activation and degree of forward bending) different bricklaying heights. Manual video analysis was used to determine duration of work tasks, frequency, type, and working height. The working heights were categorized as ‘knee’, ‘hip’, ‘shoulder’, and ‘above shoulder’. The 95 percentiles of the normalized Root Mean Square (RMSn) values were extracted assess from erector spinae and trapezius recordings to assess strenuous level muscle of muscle activation. RESULTS: The RMSn of dominant erector spinae muscle increased from hip- to shoulder height (from 26.6 to 29.6, P  < 0.0001), but not from hip to above shoulder height and decreased from hip to knee height (from 26.6 to 18.9, P  < 0.0001). For the dominant trapezius muscle, the RMSn increased from hip- to shoulder- and above shoulder height (from 13.9 to 19.7 and 24.0, respectively, P  < 0.0001) but decreased from hip- to knee height (from 13.9 to 11.5, P  < 0.0001). Compared to hip height (27.9°), an increased forward bending was detected during bricklaying at knee height (34.5°, P  < 0.0001) and a decreased degree of forward bending at shoulder- and above shoulder height (17.6° and 12.5°, P  < 0.0001, respectively). CONCLUSION: Based on technical measurements, bricklaying at hip height showed the best compromise between muscular load and degree of forward bending. This study contributes to the development of the work environment for masons and can help guide preventive initiatives to reduce physical workload. Show more

Abstract: BACKGROUND: Pushing is a typical workplace activity that may result in musculoskeletal disorders (MSDs). A convenient method of assessing the risk of MSDs is to determine the association between the force applied and the subjective rating of force exertion. OBJECTIVES: This study aimed to determine the relationship between the subjective rating of force exertion and the force applied to both a fixed and a movable handle. It also aimed to confirm that the participants could apply a higher one-handed push force at shoulder height than at elbow height. METHODS: A one-handed pushing experiment was conducted. In …the push-to-scale session, the participants pushed a handle fixed on a rig on four levels on the CR-10 scale. The push force was measured. In the force-rating session, the participants rated their force exertions when pushing a movable handle with metal blocks suspended on the two sides. The subjective ratings on the CR-10 were recorded. RESULTS: The one-handed push force at shoulder height was significantly higher than that at elbow height. More effort was needed to push on a movable handle than a fixed one. Two regression models were established to describe the relationship between the push force and the subjective ratings of pushing for each of the fixed and movable handles, respectively. The correlation coefficient results showed that these models are adequate to describe the relationship between the one-handed push force and the ratings of the CR-10 scale. CONCLUSION: Participants applied a higher one-handed push force at shoulder height than at elbow height was confirmed. Participants needed more efforts to push the movable handle under the same CR-10 level than the fixed handle. The predictive models developed in this study may be used to estimate the push force for one-handed pushing tasks when assessing the risk of MSDs. Show more
