Abstract: BACKGROUND: Considering current labour shortages, the recent increase in the number of aging workers in the labour market is deemed economically beneficial. However, due to specific characteristics (e.g. biological, generational), aging workers take longer to recover and return to work after an occupational injury. Yet, few studies have examined the rehabilitation, return, and stay at work process of aging workers and current knowledge makes it difficult for stakeholders to identify which interventions to use with this specific population. OBJECTIVE: This study aimed to describe which interventions are used in the rehabilitation, return, and stay at work …process of aging workers having suffered an occupational injury. METHODS: We conducted a five-step scoping review. Five databases were used for the literature search. A qualitative analysis of the retained manuscripts was conducted. RESULTS: Our analysis led to the extraction of information from seven manuscripts that concern the rehabilitation, return, and stay at work process of aging workers who suffered an occupational injury exclusively. We identified 19 interventions (e.g. work capacity development, work task modifications, permanent part-time work, and alternative roles) and were described according to the different phases of the Cycle of Work Disability Prevention (CWDP). CONCLUSIONS: This study offers informative, non-prescriptive, and operational interventions useful for stakeholders who support aging workers. Furthermore, it is a knowledge base to develop future projects that promote the rehabilitation, return, and stay at work process of aging workers. Show more

Abstract: BACKGROUND: Despite the physical nature of the occupation many firefighters have low levels of physical fitness which is associated with poor performance of occupational tasks and increased injury rates. For many fire departments an initial step in promoting health and wellness within the department is to conduct annual fitness testing. OBJECTIVE: To examine the effects of implementing a consequential fitness assessment within a fire department. METHODS: A retrospective repeated measures design was used to analyze annual fitness assessment data of professional firefighters (n  = 1415) from 2019 to 2022 within a large urban fire department located in …the mid-Atlantic region of the United States. The fitness tests included assessments of pull-ups, push-ups, sit-ups, aerobic capacity, and body composition. Repeated measure analyses of variances (ANOVAs) assessed the effect of year and a 2-way ANOVA was conducted to investigate the effects of sex and age on fitness measures on 2022 data. RESULTS: All fitness measures were found to be maintained over the 4-year period. Significant main effects of age and sex across all fitness measures, but no significant interactions were found. Older firefighters (50 + years) exhibited lower performance (p  < 0.001, d > 0.80) on muscular fitness assessments than young firefighters (20–29 years). A large effect of sex (males > females) was found for pull-ups (d = 1.04), push-ups (d = 1.23), and aerobic capacity (d = 1.38). CONCLUSIONS: The results suggest that implementing a consequential fitness assessment could help maintain firefighters’ fitness levels over a multi-year period. Show more

Abstract: BACKGROUND: There is a lack of information about the optimal setup of multiple screen configurations in virtual reality (VR) office work. OBJECTIVE: The objective of this study was to evaluate the effects of different screen configurations on neck flexion, rotation, neck muscle activity, and simulator sickness symptoms during Virtual Reality (VR) office work. METHODS: Twelve participants (7 males; 21 to 27 years old) performed copy-paste and drag-drop tasks in three different screen configurations (single screen, primary-secondary screen, and double screen) in a randomized order. Optical motion capture system, electromyography (EMG) device, and simulator sickness questionnaire (SSQ) …were used to measure the users’ responses. RESULTS: Neck rotation angles, muscle activities, and VR sickness were significantly affected by the screen configurations (p  < 0.021). The primary-secondary screen showed the highest right rotation angle (median: -33.47°) and left sternocleidomastoid (SCM) muscle activities (median: 12.57% MVC). Both single (median: 22.42) and primary-secondary (median: 22.40) screen showed the highest value of SSQ. CONCLUSIONS: The screen configurations in VR could be an important design factor affecting the users’ physical demands of the neck and VR sickness symptoms. Asymmetric neck rotations caused by the primary-secondary screen conditions should be avoided. Show more

Abstract: 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. Show more

Abstract: BACKGROUND: In the discourse on the heterogeneity of gender and environmental concern, gender equality awareness can further illuminate the complexity of gender and environmental concern across different cultural backgrounds. OBJECTIVE: Differing from prior research, our study focuses on exploring the relationship between different genders, gender equality awareness, and environmental concern, as well as investigating whether gender equality awareness has distinct effects on environmental concern among different genders. METHODS: Utilizing data from the 2021 China General Social Survey (CGSS), we conducted a theoretical investigation into gender differences in environmental concern. First, we used descriptive statistics to observe …the differences between the samples. Secondly, in order to compare the influence of gender equality awareness on different genders, we conducted t -tests on gender subgroups. Subsequently, an Ordinary Least Squares (OLS) regression model was employed to examine the effects of gender and gender equality awareness on environmental issues. Finally, gender equality awareness was introduced as a moderating variable to explore its potential interaction with gender and investigate whether a moderation mechanism exists between gender and environmental concern. RESULTS: Findings indicate that 1) male respondents in China exhibit greater concern for the environment compared to female respondents; 2) higher levels of gender equality awareness are positively correlated with higher levels of environmental concern; 3) the influence of gender on environmental concern is moderated by the degree of gender equality awareness. Specifically, when gender equality awareness is strengthened, female respondents exhibit a higher degree of environmental concern. CONCLUSION: Enhancing gender equality awareness contributes to improving both social gender equality and equitable concern for the environment. The findings could provide insights for similar developing countries like China. Show more

Abstract: BACKGROUND: Problem-based learning (PBL), a student-centered approach which has been implemented in many educational institutes worldwide. OBJECTIVES: This study aimed to evaluate and compare the proficiency of students in 5 key areas of PBL process and assess perceptions of students towards PBL learning using a self-explanatory questionnaire. METHOD: This cross-sectional study was conducted from March 2020 to September 2022 and evaluated perceptions of 1st year dental students of Batch 2021 (having Face-to-face PBL sessions) and batch 2020 (having online PBL sessions) using a questionnaire. Three similar PBL cases were used, which assessed PBL parameters that …included attendance, group dynamics, knowledge, communication skills and preparation. Statistical analysis was performed for all the categorical and continuous variables. RESULTS: Majority of Distance Learning (DL) group (66.7%) concurred that PBL helped improve their communication skills, decision making power (66.7%), self-directed learning (80%) and promoted interaction with peers (66.7) and teachers (68.9%). The Face –to- Face (FF) group demonstrated better scores (7.7±2.42 & 7.55±2.55) with respect to their attendance and group dynamics (7.44±2.17 & 8.02±2.40) in PBL 1 & 3 as compared to DL group. Overall, better performance in all the 5 key areas of PBL was observed for the FF group versus the DL group. CONCLUSION: The Distance learning (DL) group displayed a positive attitude and perception towards PBL as a learning strategy whereas Face-to-face (FF) group showed greater performance and proficiency in the key PBL parameters scores.

Abstract: BACKGROUND: Work-related musculoskeletal disorders (WRMSDs) is a multi-factorial disorder in most occupational setting and it has increased significantly in recent years. OBJECTIVE: This study aimed to investigate the relationship between physical, cognitive, and environmental factors of ergonomics with the prevalence of WRMSDs in a car-parts manufacturing industry METHODS: This cross-sectional study was performed among 220 workers in a milling unit of a car parts manufacturing company in 2021-2022. The prevalence of WRMSDs was assessed using the Extended Version of the Nordic Musculoskeletal Questionnaire. Noise exposure was evaluated using dosimetry method. Mental and physical …workload were evaluated by the NASA-TLX and key index methods (KIM-MHO and KIM-LHC), respectively. Data analysis was performed using SPSS version 25.0. RESULTS: The subjects’ mean age and work experience were 36.3±6.5 and 8.35±6.41 years, respectively. Eighty-five percent of the subjects reported WRMSDs in at least one area of the body. The results of mental workload assessment revealed a high workload mean range (73.23±14.89) in all of the subjects. Mean score of KIM-LHC and KIM-MHO were 738.18±336.42 and 201.86±36.41, respectively with odds ratio of 1.32 for KIM-LHC in creating the WRMSDs. There was a significant relationship between the noise exposure, mental and physical workload and the prevalence of WRMSDs (p -value < 0.05). CONCLUSION: The results of the present study revealed that environmental, physical and cognitive factors can simultaneously be effective in the prevalence of WRMSDs. Therefore, performing effective control measures requires comprehensive attention to physical, environmental, and cognitive ergonomics in the algorithm of ergonomics management in the workplace.

Abstract: BACKGROUND: Sexually Transmitted Infections (STIs), such as Human Immunodeficiency Virus (HIV) transmitted by biological, socioeconomic and cultural factors that increase the vulnerability of certain population groups such as civil construction workers. OBJECTIVE: To evaluate the knowledge of workers in the construction industry about infection by HIV and associated factors. METHODS: A cross-sectional, analytical study was conducted, including 381 construction workers, in the cities of João Pessoa, Cabedelo, and Santa Rita, in the State of Paraíba, Brazil, performed through interviews, using a data collection instrument with social demographic variables and the HIV Knowledge Questionnaire. Data were analyzed …using descriptive measures, and for comparison between the categories the Kruskal-Wallis test was used, with margin of error of 5%. RESULTS: A predominance of male workers was observed (97.4%) among 381 workers; aged 30-39 (34.1%); married (81.4%); with up to eight years of education (66.6%); family income of up to 2x the minimum wage (52.8%) and coming from the country (43.8%). The average of correct responses was 63.3%, with higher indices (70.0%) related to transmission and forms of prevention. There were higher percentages of hits among those who had studied for 12 years or more. Workers from the capital of Paraíba presented a higher number of correct responses (67.44%). CONCLUSIONS: There is a low index of knowledge of construction workers about HIV, highlighting their consequent vulnerability to acquiring this infection. Show more

Abstract: BACKGROUND: Self-reported test is one of the main psychosocial risk assessment tools. However, this test it is susceptible to certain sources of error, including social desirability. Since psychosocial risks are emerging, there are not many studies on their assessment. OBJECTIVE: The aim of this work is to analyze the impact of social desirability on the short version of the CopSoq-ISTAS 21 assessment tool. METHOD: A total of 563 workers (45.10% women and 54.90% men) participated in this study. The short version of the CoPsoQ-Istas21 questionnaire with four Likert scale questions as markers, which …correspond to the Eysenck Personality Lie Scale Questionnaire Revised (EPQ-r), were used. The sample was divided into two halves, and both a confirmatory analysis and an exploratory analysis were carried out to find out the factorial structure of the scale and, with it, apply the bias filtering method. RESULTS: The results indicate that 10% of the scale is biased due to social desirability, and that there are significant differences between the group with bias clean scores and the group with scores without bias control. CONCLUSIONS: The effects of social desirability on the scale are verified, so it is concluded that in a psychosocial risk assessment is not enough to apply a self-report test and interpret its results, being necessary to minimize the sources of error.

Abstract: BACKGROUND: The American Conference of Governmental Industrial Hygienists (ACGIH) Threshold Limit Values (TLVs) for Lifting is a manual material handling (MMH) assessment method to identify weight limits that nearly all workers may be exposed to without developing work-related low back disorders (LBD). However, this assessment method only applies to lifting with the torso within 30° asymmetry of the sagittal plane. OBJECTIVE: Estimate TLV weight limits while lifting with torso asymmetry greater than 30° beyond the sagittal plane. METHODS: Lifting tasks were performed from various horizontal and vertical locations, at torso asymmetry angles of 0°, 15°, 30°, …45°, 60°, 75° and 90°, using ACGIH identified TLVs. Validated MMH assessment methods (NIOSH Lifting Equation, Ohio State University LBD Risk Model) were utilized to estimate TLVs at torso asymmetries greater than 30°. RESULTS: The current ACGIH TLVs resulted in low- to moderate-risk risk levels for torso asymmetries from 0° to 30°, and the risk incrementally increased as torso asymmetry increased to 90°. With the intention to keep the risk levels to that found at 30° torso asymmetry, lower TLV weight limits in the vertical and horizontal zones investigated were estimated for torso asymmetries from 45° to 90°. The resulting adjusted TLVs were consistent with weight limits identified for similar lifting conditions from other assessment methods that account for torso asymmetry. CONCLUSIONS: This research found current ACGIH-defined TLVs possess less than high-risk for LBD, and provided guidance to practitioners for reduced TLVs when torso asymmetry is greater than 30° from the sagittal plane.

Abstract: BACKGROUND: Vibration is one of the harmful factors for forklift drivers. The use of non- standard seats and not paying attention to how the seats are maintained can be affected by the amount of vibration transmitted to the person. OBJECTIVE: This study investigates the amount of vibration transmitted from the forklift and the effect of different types of polyurethane foam in reducing the vibration transmitted from the forklift seat. METHODS: This descriptive-analytical study was performed on 38 forklifts in 4 diesel models with the same weight class. The amount of vibration transmitted from forklift seats according …to ISO2631 standard, taking into account the effect of various factors such as foam type (hot and cold), thickness (6–12 cm), load and year Function was measured. The amount of vibration caused by the forklift on the seat and under the seat was evaluated using ISO7096 standard. RESULTS: The average total vibration of the whole body in all foams in no-load mode is more than with load. The transmission vibration of cold polyurethane foam is less than that of hot polyurethane foam. With increasing thickness, the efficiency of cold polyurethane foam increases by 12 cm and in the loaded state 40.63% and in the unloaded state 49.58% in reducing the vibration transmitted to drivers. CONCLUSION: The results of this study show that cold foam has better effectiveness and efficiency than hot polyurethane foam. Also, the thicker the foam, the less vibration is transmitted to the driver. Show more

Abstract: BACKGROUND: Like other things, psychological safety has a too-much-of-a-good-thing effect on the risk prevention process. There are warranted systematic and theoretical discussions on both positive and negative influences of psychological safety, which provide useful guides to handling potential risks for workers. OBJECTIVE: This study focuses on the psychological safety analysis of work safety for workers in high-risk industries through the construction of a theoretical model, illustrating that a higher level of psychological safety is not better. METHOD: This study explores the impact of workers’ psychological safety on the potential risk of work safety by conducting a …comprehensive analysis of relevant literature and employing inductive reasoning and analogy methodology. RESULTS: We systematically reviewed the research background and several hypotheses of psychological safety, described the relationship between psychological safety and risk prevention from three levels, and constructed the threshold initial, special, and extended model of psychological safety to reveal the importance of workers’ psychological safety when handling potential risks. CONCLUSION: This research effectively describes the influence of high, moderate, and low levels of psychological safety on the risk prevention of work safety, which provides a psychological model guide to developing measures for the improvement of work safety management.

Abstract: BACKGROUND: Ethnic minorities make up approximately 14% of the UK workforce. Despite the disproportionate burden of ill-health amongst ethnic minorities, and the increased interest in Diversity, Equity & Inclusion (DE&I) in the workplace, workplace health and wellbeing interventions are still most often designed for the ethnic majority. OBJECTIVE: The purpose of this scoping review was to explore the depth and breadth of evidence on the attitudes to and perceptions of health and wellbeing interventions in the workplace within ethnic minority groups in the UK, and to identify gaps in evidence that would provide direction for future …research needs. METHODS: A scoping review with quality appraisal was undertaken, supplemented by a review of grey literature and a narrative review exploring related evidence from the knowledge bases related to community and cultural adaptation. RESULTS: Only three peer-reviewed studies met inclusion criteria, preventing broad conclusions. 14 papers from the community and cultural adaptation literature provided additional information about how health promotion may be approached effectively in the workplace, including the importance of culturally sensitive, people-centred design, and the use of established adaptation frameworks. CONCLUSION: The literature suggests a need for improvements in four key areas: (1) reporting of ethnic minorities in data relating to workplace health and wellbeing research, (2) more thorough review of perceptions and attitudes of ethnic minority workers in the UK, (3) design of culturally appropriate interventions that are tested for impact, and (4) testing of the effectiveness of culturally adapted interventions.

Abstract: BACKGROUND: Low back pain is a common health issue, and such pains are often associated with muscle tightness. Understanding the link between lower back pain and tight lower extremity muscles is essential for effective pain management and enhanced quality of life. OBJECTIVE: The objective of this study was to investigate the relationship between lower extremity muscle tightness and pain and disability in individuals with non-specific low back pain (NSLBP). METHODS: A total of 52 individuals with NSLBP were enrolled in this cross-sectional study. Lower extremity muscle tightness was assessed using various clinical tests, …including the Active Knee Extension Test, Active Straight Leg Raise, Ober Test, and Modified Thomas Test. Pain intensity and disability were evaluated using the Visual Analog Scale and the Oswestry Disability Index, respectively. Statistical analyses were conducted to assess the correlation between muscle tightness, pain, and disability. RESULTS: The study found weak to moderate negative correlations between lower extremity muscle tightness and both pain intensity and disability in individuals with NSLBP (r: –0.287 to –0.526, p  < 0.05). Dominant and non-dominant extremities exhibited differences in muscle flexibility, with the dominant extremity showing greater flexibility (p  < 0.05). CONCLUSIONS: In individuals with NSLBP, lower extremity muscle tightness is closely related to pain severity and disability. These findings suggest that lower extremity muscle tightness plays a significant role in the severity of low back pain and disabilities. Additionally, the observed flexibility difference between dominant and non-dominant extremities warrants further investigation for more personalized treatment approaches. Show more

Abstract: BACKGROUND: Mild traumatic brain injury (mTBI) can profoundly impact overall health, employment, and family life. Incidence of mTBI in the workplace represents an important subgroup with poorer outcomes. Mental health (MH) and substance use (SU) challenges are a primary correlate of TBI, but are rarely assessed among individuals with a work-related (wr)-mTBI, particularly at a population-level. OBJECTIVE: This study aimed to assess the association between lifetime wr-mTBI and non-wr-mTBI and the experience of MH and SU challenges. METHODS: The 2019 Centre for Addiction and Mental Health (CAMH) Monitor is a cross-sectional telephone survey …of adults aged≥18 years in Ontario, Canada, employing a stratified (six regions) two-stage (telephone number, respondent) list-assisted random digit dialing probability selection procedure (N = 1792). Adjusting for sociodemographic variables, binary logistic regression was conducted to assess the association between lifetime wr-mTBI and non-wr-mTBI (relative to no TBI) and four outcomes: hazardous use of alcohol and of cannabis, psychological distress, and fair/poor mental health. RESULTS: Adjusting for sociodemographic variables, non-wr-mTBI demonstrated increased odds of hazardous alcohol (AOR = 2.12, 95% CI = 1.41, 3.19) and cannabis use (AOR = 1.61, 95% CI = 1.05, 2.45), psychological distress (AOR = 1.68, 95% CI = 1.14, 2.49), and fair/poor mental health (AOR = 1.70, 95% CI = 1.11, 2.59). Lifetime wr-mTBI demonstrated increased odds of reporting psychological distress (AOR = 3.40, 95% CI = 1.93, 5.97) and fair/poor mental health (AOR = 2.16, 95% CI = 1.12, 4.19) only. CONCLUSIONS: Non-wr-mTBI was associated with both MH and SU, whereas wr-mTBI was associated with MH only. MH outcomes were more strongly associated with wr-mTBI than non-wr-mTBI. Physicians, employers, and insurers need to consider the potential association between wr-mTBI and MH, and provide care accordingly. Show more

Abstract: BACKGROUND: Unemployment and restricted work opportunities for youth are enduring social challenges that affect health, well-being, and quality of life, especially in low- to middle-income countries. When considering the advantages associated with work as a determinant of health, unemployment is understood to contribute to occupational injustice. However, self-employment, hailed the solution to youth unemployment, is often necessity-driven, precarious in nature and restricted by the low success rate of business start-ups. OBJECTIVE: Research was undertaken to explore factors perceived to contribute to the success of start-up businesses in an informal settlement in the Western Cape of South …Africa. The importance of support in the success of business start-ups will be the focus of this article. METHODS: A collective case study, using narrative interviewing and - analysis, was undertaken in South Africa. Two narrative interviews were conducted with each of the five participants who were youth entrepreneurs and founders of start-up businesses. Data analysis comprised the use of narrative analysis and paradigmatic type narrative analysis. RESULTS: Three themes captured factors deemed to have contributed to the success of start-up businesses. The vital role of support systems and networks in business success was demonstrated.

Abstract: 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.

Abstract: BACKGROUND: In the context of smart mine construction, coal mine safety management is imposing stringent requirements on the safety competence of miners. To meet these demands, coal mine enterprises have initiated proactive measures to recruit a new generation of knowledge-based miners who possess high qualifications and specialized backgrounds. OBJECTIVE: This study aims to explore the underlying mechanisms of identity conflict (IC) and its influence on unsafe behavior (USB) among KBMs within the context of China’s smart mining initiatives, as well as to identify the role of potential mediating and moderating variables in this relationship. …METHODS: An empirical study was conducted on a sample of 304 KBMs with a college degree or above, selected from multiple coal mines in Shanxi Province, China. Hierarchical regression analysis and the Bootstrap method were employed for data analysis. This model incorporated IC as the antecedent variable and meticulously investigated the mediating effects of role breadth self-efficacy (RBSE) and psychosocial resources (PSR), along with the moderating effect of positive explanatory bias (PEB). RESULTS: The findings indicate a significant positive correlation between IC and USB among KBMs. RBSE and PSR were found to mediate the relationship between IC and USB. Moreover, this mediating effect further influenced the relationship between IC and USB through a chain mediating effect. Additionally, PEB strengthened the positive impact of KBMs’ RBSE on PSR. CONCLUSION: These results provide a broader perspective on the antecedent variables associated with KBMs’ USB and provide valuable insights and practical management strategies enhancing the safety management practices within coal mining enterprise.

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
