Evaluation of a Biomathematical Modeling Software Tool for the Prediction of Risk in Flight Schedules Compared Against Incidence of Fatigue Reports
Jaime K. Devine, Jake Choynowski, Steven R. Hursh
Background: Modeling tools should be tested against real-world outcomes to confirm their predictive ability compared to random chance. Insights is an analytical tool within the biomathematical modeling software SAFTE-FAST that identifies work patterns that consistently result in elevated fatigue risk. This study investigated the ability of Insights to correctly identify duties with an associated fatigue report using previously collected flight schedule and report data. Methods: Planned and completed flight roster schedules were analyzed using SAFTE-FAST Insights after the rosters had been flown. Fatigue reports were independently linked to planned and completed schedules at the duty level. Odds ratio (OR) analysis investigated the ability of Insights to predict which duties would be linked to a fatigue report. Differences in duties were compared using a one-way analysis of variance (ANOVA) and a two-sample <i>t</i>-test. Results: There were 157 fatigue reports out of 78,061 planned duties and 235 fatigue reports out of 82,612 completed duties. Insights had 3.04 odds of correctly identifying fatigue reports in planned duties but 0.41 odds for completed duties. Discussion: Insights showed good odds of correctly identifying a fatigue report duty using planned schedules but poor odds of identifying a fatigue report duty from completed schedules. Completed duties started later in the day and were shorter in duration than planned duties. Day-of-operations schedule changes may have reduced the fatigue risk in response to the fatigue reports.

Exploring the Prevalence of Burnout in Medical Residents: Socio-Demographic and Job Characteristics as Predictors in Iran
Shima Shakiba, Ahmad Sharifi, Farnaz Hashemi
et al.
Introduction: Burnout is a psychological syndrome that develops due to chronic stressors in a person's professional life, resulting in emotional exhaustion and detachment. The objective of this study was to determine the prevalence of burnout among medical residents, considering socio-demographic variables and job characteristics, and to predict burnout in this group. Medical residents often face specific pressures such as long working hours, sleep deprivation, high patient loads, and emotional demands from patient care, which contribute to their overall stress levels. Methods: A cross-sectional study was conducted in the academic year 2019-2020, involving 164 residents from two general hospitals who completed the Persian versions of the Job Content Questionnaire (JCQ) and Maslach Burnout Inventory (MBI-HSS). Results: A significant proportion of residents reported burnout symptoms, with 73.7% experiencing moderate to high levels of emotional exhaustion and 64.4% indicating moderate to high levels of depersonalization. Additionally, 90.1% of residents reported low perceived professional efficacy. Among the subscales of MBI-HSS, reduced professional efficacy was found to be the highest. Psychological demands and limited decision latitude were significant predictors of burnout, particularly in relation to emotional exhaustion and depersonalization. Conversely, support from family and co-workers, as well as higher levels of experience, were associated with lower depersonalization and improved professional efficacy. Conclusion: Overall, medical residents in Iran face significantly high levels of burnout, which are influenced by specific personal and job characteristics. Consequently, preventive and therapeutic interventions are necessary to address this pressing issues.

Disclosures of Occupational Health and Safety Performance Indicators: A Perspective from South African Listed Companies
Oscar Rikhotso
Employers in South Africa are mandated by labour laws to implement systems of work for the maintenance and promotion of health and safety at work. In response, companies have adopted and implemented occupational health and safety management systems (OHSMSs) whose effectiveness should be continuously monitored through performance measurement. However, there remains no national convention on the specific performance measurement indicators for companies to use. The objective of this study was to determine, characterise and compare lagging indicators adopted and reported by the top 150 Johannesburg Stock Exchange (JSE)-listed companies in South Africa. This qualitative study evaluated annual reports and data books from these companies by analysing textual data through qualitative document analysis. Only 87 of the 150 case companies reported performance using lagging indicators. The basic materials, consumer goods, consumer services and industrial sectors had the most companies which reported performance metrics. Fatality count and lost time injury frequency rate (LTIFR) were the most commonly reported performance metrics and were reported by 64 and 41 companies, respectively. There was variation in the number, type and form of adopted lagging indicators by the case companies. Companies in the manufacturing and mining sectors were more likely to report OHS performance, in general, than those in other sectors. The observed variation across sectors emphasises the need for harmonised indicators to measure and report OHS performance in South Africa.

Multilevel Safety Climate for Lone Heavy Vehicle Drivers in the UK Quarrying Industry: Validation of the Heavy Vehicle Safety Climate Scale (HVSCS)
Jim Morgan, Laura Jackson, Matteo Curcuruto
The primary goal of our research was to validate a context-specific safety climate measure (the Heavy Vehicle Safety Climate Scale: HVSCS) in a sample of heavy mobile equipment operators (N = 277). An exploratory strategy was adopted, using exploratory factor analysis (EFA) to validate the items. The statistical results revealed a five-factor structure, with two factors at the organisational level and three factors at the group level. In addition, a nomological analysis showed that both organisational and supervisory safety climate factors presented distinct correlation patterns with other safety-related variables, including situational and routine violations, safety citizenship behaviour, context-specific safety behaviours and risk propensity. In this study we developed and psychometrically validated a context-specific safety climate tool for lone heavy vehicle drivers in the quarrying industry: the Heavy Vehicle Safety Climate Scale (HVSCS). It is hoped that the final 37-item HVSCS will be utilised by those managing heavy vehicle operations, particularly in the quarrying industry, to identify context-specific opportunities for safety climate improvements and in turn reduce the risk of safety incidents.

Digital and Virtual Technologies for Work-Related Biomechanical Risk Assessment: A Scoping Review
Paulo C. Anacleto Filho, Ana Colim, Cristiano Jesus
et al.
The field of ergonomics has been significantly shaped by the advent of evolving technologies linked to new industrial paradigms, often referred to as Industry 4.0 (I4.0) and, more recently, Industry 5.0 (I5.0). Consequently, several studies have reviewed the integration of advanced technologies for improved ergonomics in different industry sectors. However, studies often evaluate specific technologies, such as extended reality (XR), wearables, artificial intelligence (AI), and collaborative robot (cobot), and their advantages and problems. In this sense, there is a lack of research exploring the state of the art of I4.0 and I5.0 virtual and digital technologies in evaluating work-related biomechanical risks. Addressing this research gap, this study presents a comprehensive review of 24 commercial tools and 10 academic studies focusing on work-related biomechanical risk assessment using digital and virtual technologies. The analysis reveals that AI and digital human modelling (DHM) are the most commonly utilised technologies in commercial tools, followed by motion capture (MoCap) and virtual reality (VR). Discrepancies were found between commercial tools and academic studies. However, the study acknowledges limitations, including potential biases in sample selection and search methodology. Future research directions include enhancing transparency in commercial tool validation processes, examining the broader impact of emerging technologies on ergonomics, and considering human-centred design principles in technology integration. These findings contribute to a deeper understanding of the evolving landscape of biomechanical risk assessment.

I. Moreira-Silva, R. Queiros, N. Ventura
et al.
According to previous studies, the prevalence of musculoskeletal symptoms among call center operators is high. However, although this is a developing occupation in Portugal, there is a lack of studies assessing this issue as well as its associations with different risk factors. Therefore, the aim of this study is to investigate the 7-day and 12-month prevalence of musculoskeletal symptoms among Portuguese call center operators and their associations with gender, body mass index, hours of work and sitting time. The study was conducted in a call center company in Portugal. One-hundred and forty-eight workers agreed to participate, and filled out questionnaires to evaluate sociodemographic, anthropometric, and occupational variables, as well as the Nordic Musculoskeletal Questionnaire (NMQ) to assess musculoskeletal symptoms in the last 7 days and 12 months of 9 body regions. NMQ revealed the 12-month prevalence of musculoskeletal symptoms, the 3 most affected body regions were the neck (56.1%), the low back (54.7%) and the shoulders (43.9%). And the 7-day prevalence, the three most affected body region were the same, but in different percentages: low back (31.8%), neck (23.6%) and shoulders (21.6%). Significant associations were found between gender and reporting symptoms in the wrist/hands (p=0.033) and the knees (p=0.031), with females reporting significantly more symptoms than males; and between body mass index and reporting symptoms in the thighs/hips, with overweight operators reporting more symptoms (p=0.010). No significant associations were found for the hours of work, neither in sitting time. Conclusion: Workplace interventions are needed to decrease the prevalence of musculoskeletal complaints among call center workers.

Biological hazards that can affect the health of the workers that handle hospital waste
Trajano Felipe Barrabas Xavier da Silva, Humberto Costa, Marcelo Ribeiro
et al.
Technological advances allow the science development, with the creation of new materials / equipment and the offer of different products and services. Some of these materials, after use, are discarded, becoming waste. Mismanagement of these wastes and improper handling within the hospital environment can cause serious harm to workers' health. Comprehensive studies in hospital settings are essential to increase knowledge about the risks that workers are exposed to, including biological hazards. Thus, a systematic review is proposed to obtain relevant information on these risks to plan future interventions appropriate to avoid related negative consequences. Thus, following the preferential reporting items for systematic reviews and meta-analysis protocols (PRISMA-P), this systematic review protocol was developed with the objective of presenting suitable guidelines for the development of a research that can provide results to meet the goal sought. Five databases will be accessed (SCOPUS, PubMed, Science Direct, EBSCOhost and Web of Science) and a total of 9 keyword combinations will be used. This protocol is registered in PROSPERO under the code of PROSPERO CRD42019127145

Opportunities for Using Building Information Modeling to Improve Worker Safety Performance
Kasim Alomari, John Gambatese, Jason Anderson
Building information modelling (BIM) enables the creation of a digital representation of a designed facility combined with additional information about the project attributes, performance criteria, and construction process. Users of BIM tools point to the ability to visualize the final design along with the construction process as a beneficial feature of using BIM. Knowing the construction process in relationship to a facility’s design benefits both safety professionals when planning worker safety measures for a project and designers when creating a project’s design. Success in using BIM to enhance safety partly depends on the familiarity of project personnel with BIM tools and the extent to which the tools can be used to identify and eliminate safety hazards. In a separate, ongoing study, the authors investigated the connection between BIM and safety to document the opportunities, barriers, and impacts. Utilizing an on-line survey of project engineers who work for construction firms together with a comprehensive literature review, the study found those who use BIM feel that it aids in communication of project information and project delivery, both of which have been found to have positive impacts on construction site safety. Further, utilizing the survey results, the authors apply the binary logistic regression econometric framework to better understand the factors that lead to safety professionals believing that BIM increases safety in the work place. In addition, according to the survey results, a large percentage of the engineers who use BIM feel that ultimately it helps to eliminate safety hazards and improve worker safety. The study findings suggest that improvements in safety performance across the construction industry may be due in part to increased use of BIM in the construction industry.

Factors Influencing Learner Permit Duration
Johnathon P. Ehsani, Kaigang Li, Brydon J. B. Grant
et al.
An increasing number of countries are requiring an extended learner permit prior to independent driving. The question of when drivers begin the learner permit period, and how long they hold the permit before advancing to independent licensure has received little research attention. Licensure timing is likely to be related to “push” and “pull” factors which may encourage or inhibit the process. To examine this question, we recruited a sample of 90 novice drivers (49 females and 41 males, average age of 15.6 years) soon after they obtained a learner permit and instrumented their vehicles to collect a range of driving data. Participants completed a series of surveys at recruitment related to factors that may influence licensure timing. Two distinct findings emerged from the time-to-event analysis that tested these push and pull factors in relation to licensure timing. The first can be conceptualized as teens’ motivation to drive (push), reflected in a younger age when obtaining a learner permit and extensive pre-permit driving experience. The second finding was teens’ perceptions of their parents’ knowledge of their activities (pull); a proxy for a parents’ attentiveness to their teens’ lives. Teens who reported higher levels of their parents’ knowledge of their activities took longer to advance to independent driving. These findings suggest time-to-licensure may be related to teens’ internal motivation to drive, and the ability of parents to facilitate or impede early licensure.

THE APPROACH TOWARDS THE ESTIMATION OF THE ARTILLERY AND ROCKET TROOPS “FIRE FOR EFFECT” ON ENEMY MODERN UNMANNED AIRCRAFT COMPLEX POSITIONS EFFECTIVENESS
Yurii Y. Repilo, Oleksii O. Riman, Dmytro D. Demydko
The approach towards the estimation of the artillery and rocket troops “fire for effect” on enemy modern unmanned aircraft complex positions, which, unlike the existing approach, takes into account main (reconnaissance) function of the complex in modern combat conditions. The features of such conflicts are distinct “fire nature” and integration of reconnaissance and “fire for effect” means into reconnaissance-fire system. The core function of this system is the implementation of the most appropriate from available “fire for effect” means on reconnoiter object (target) at any moment of operation. Reconnaissance-fire system combat effectiveness is presented by the number of our troops destroyed targets, which are unified into relatively homogenous combat elements. The reduction of reconnaissance-fire system combat effectiveness due to the unmanned aircraft positions fire damage dealt by rocket troops and artillery is characterized by the “fire for effect” efficiency, dependent on the number of destroyed complexes of appropriate class. System combat effectiveness is defined with the use of method of dynamic alteration of our troops main elements average quantity. Our troops take part in fire confrontation and under the influence of enemy reconnaissance-fire system change corresponding conditions. One of the values characterizing the intensity of the elements condition change is the intensity of enemy on our objects reconnaissance, which value is a result of enemy reconnaissance functioning results multiplication, among them unmanned aircraft complexes.
