    Notifications that related 1st degree burns to reflective striping and impermeable clothing elements did reach the investigators, while the mechanisms behind this phenomenon are still unclear. Material tests for thermal and evaporative resistance, and for heat transmission under dry and wet conditions at low radiation levels were done to evaluate the performance of protective clothing with and without printed logos or reflective striping. The results under the specified conditions showed reduction of heat loss capacity under impermeable elements from dry to wet conditions. Reflective surfaces, even when more impermeable, showed still lower heat transmission through the textile package than materials without striping under tested moisture and radiation combinations. It can be expected that the reported 1st degree burns were related to clothing design and tightness/fit rather than to reflective striping. However, due to the fine balance between clothing thermal and evaporative resistance, outer material emissivity, moisture quantity and location in clothing and applied radiation level, a different setup could lead to different results.

    Rotating shift work is associated with an increased risk of cardiovascular disease (CVD). This study compared the CVD risk score in 129 male line workers aged 22–49 years on different shifts in a medium-sized metal production factory from 2017 to 2020. We classified workers into four groups: permanent day shift, weekly rotation involving five consecutive nights, weekly rotation involving 3–4 consecutive nights, and monthly rotation involving two consecutive nights. We used the Framingham Risk Score to estimate the 30-yr risks of general and hard CVD (CVD risk estimates). We investigated the differences in CVD risk estimates between different groups using linear mixed models. The average 30-yr Framingham CVD risk estimates of each group ranged from 17.5% to 31.2% for general CVD and from 10.5% to 20.5% for hard CVD. Workers on weekly rotations involving 3–5consecutive nights had 5%–10% significantly higher CVD risk estimates than workers on the permanent day shift. Workers on weekly rotations also had 6%–8% higher BMI-based CVD risk estimates than those on the monthly rotation involving two consecutive nights. While 24-h shift rotations are unavoidable, our findings underscored the potential CVD risk among workers on weekly rotations involving more consecutive nights.

    Job strain is considered a potential risk factor of cardiovascular disease (CVD). Our objective was to examine prospective associations of job strain with CVD mortality using data from the national, population-based Mid-life in the United States (MIDUS) cohort study, while considering changes in job strain. Job strain measure was based on Demand-Control model at Wave 1 in 1995-1996 and Wave 2 in 2004-2006, and CVD mortality data through 2018 were retrieved through linkage to the National Death Index (NDI). Cox proportional hazards regression was applied to assess prospective associations between job strain across MIDUS I and MIDUS II and CVD mortality at follow-up in 1,870 workers free from CVD at MIDUS I. After adjustment for relevant covariates, single measurement of job strain at MIDUS I or MIDUS II, and two measurements of job strain between the two waves were not significantly associated with CVD mortality, while the increase in scores between the two waves (increase vs. no increase) demonstrated stronger prospective associations with CVD mortality (HR and 95% CI=2.37 [0.88, 6.42]). Our findings suggest increased job strain may pose a stronger risk to CVD mortality than single exposure measurement.

    The COVID-19 pandemic resulted in a sudden switch to remote working that many organisations and workers were unprepared for. The study investigates the perceived impact of remote working on workers’ health and influencing factors. The topic has received limited attention within published studies. A cross-sectional online survey was distributed to IT and communication remote workers in Malta (N=459). Closed-ended questions were analysed quantitatively in order to identify perceived changes in health. Open-ended questions were analysed qualitatively to determine the perceived reasons for such changes. More workers reported that their health had deteriorated than improved during the first 12 months of the pandemic. Greater proportions of remote work were associated with improved levels of health. Several factors were perceived to have influenced levels of health, including: health behaviours, such as physical activity, nutrition, and sleep; the development of disease, particularly mental health issues; work related factors, such as social support, work demands, and the blurring of work-life boundaries; and personal factors, including family life and leisure. The study concludes that remote working can be beneficial for health when workers engage in the correct health-promoting behaviours and are provided with the necessary support, both during their working and private life.

    The home has become a new physical workplace, and can therefore influence the work, health, and life of workers. This cross-sectional study aimed to evaluate the chronology of the effects of work hazards at home on factors such as workers’ health, productivity, and well-being (WB). Information on novice working-from-home (WFH) workers was derived from the “Occupational health of WFH” project. The selected variables in the hypothesis model comprised problems such as perceived indoor environmental quality (IEQ), working conditions (WC), sick house syndrome (SHS), occupational stress (OS), work productivity (WP), and WB. The relationship between these variables was analyzed using a structural equation model. The group analysis results showed the following significant indirect path effects from work environment through WP: IEQ-> SHS->OS->WP. A non-significant direct effect was observed between IEQ and WP. While WC problems could also have a significant direct effect on WP, or be mediated by OS, WP is a significant consequence and a direct effect of WB. In conclusion, the WFH model’s causal impact between home environment, WP, and WB is a physio-psychological pathway. Therefore, creating a healthy home environment and WC, along with OS management, comprise important issues for improving productivity and WB for this new work style.

    This study (1) evaluated the perceptual and objective physical quality of digital radiographic chest images processed for different purposes (routine hospital use, lung cancer screening, and pneumoconiosis screening), and (2) quantified objectively the quality of chest images visually graded by the Japan National Federation of Industrial Health Organization (ZENEIREN). Four observers rated the images using a visual grading score (VGS) according to ZENEIREN’s quality criteria. Signal-to-noise ratio (SNR) and contrast-to-noise ratio (CNR) were measured. Between groups, differences were assessed using ANOVA (followed by Bonferroni multiple comparisons) or unpaired t-test. The Pearson’s correlation coefficients were calculated for the correlation between perceptual quality and objective physical image quality. The image quality perceived by the observers and the SNR measurements were highest for the images generated using parameters recommended for lung cancer screening. The images processed for pneumoconiosis screening were rated poorest by the observers and showed the lowest objective physical quality measurements. The chest images rated high quality by ZENEIREN generally showed a higher objective physical image quality. The SNR correlated well with VGS, but CNR did not. Highly significant differences between the processing parameters indicate that image processing strongly influences the perceptual quality of digital radiographic chest images.

    Due to the COVID-19 pandemic, the number of employees in flexible work from home has increased markedly along with a reliance on information communication technologies. This study investigated the role of an organisational factor, psychosocial safety climate (PSC; the climate for worker psychological health and safety), as an antecedent of these new kinds of demands (specifically work from home digital job demands) and their effect on work-life conflict. Data were gathered via an online survey of 2,191 employees from 37 Australian universities. Multilevel modelling showed that university level PSC to demands, y=−0.09, SE=0.03, p<0.01, and demands to work-life conflict, y=0.51, SE=0.19, p<0.05, relationships were significant. Supporting the antecedent theory, university level PSC was significantly indirectly related to work-life conflict via demands (LL −0.10 UL −0.01). Against expectations PSC did not moderate the demand to work-life conflict relationship. The results imply that targeting PSC could help prevent work from home digital job demands, and therefore, work-life conflict. Further research is needed on the role of digital job resources as flexible and hybrid work takes hold post COVID.

    This study was conducted to check whether benzene is contained inside the petroleum-based cleaning agent used in the printing industry and measure whether it is actually exposed to the air. Benzene was analyzed inside the cleaning agent and air exposure evaluation was done by area sampling. Risk assessment was performed using the CHARM (Chemical Hazard Risk Management) technique. Most products contained benzene based on the results obtained from this study. As a result of collecting air samples and checking whether the workers were exposed to benzene actually, benzene was detected in three samples. As a result of the risk assessment, most of printing businesses scored more than four points. Benzene was detected in all petroleum-based cleaning products. In addition, benzene was detected in some of air samples. Considering the fact that even small exposure level of benzene is dangerous to worker health and most of the printing businesses in South Korea operate on a small scale with fewer than five employees so the health management system is poor, it is necessary to prepare appropriate measures to prevent work diseases provoked by benzene exposure.

    Short rest (<11h) between evening and day shifts – known as quick returns (QRs) – impede recovery and may impair health. Nevertheless, QRs remain popular among some shift workers. This study explores nurses’ and nursing assistants’ perceptions of the merits and demerits of QRs from individual and organizational perspectives. Participants were recruited from eleven wards at two Swedish hospitals as part of a larger quasi-experimental intervention study. The majority (79%) had influence over their work schedules. Frequency distributions of responses are presented. Ninety six undertook a baseline survey regarding recovery, tolerance and work performance in relation to QRs. A majority experienced difficulties unwinding before bedtime (76%), insufficient sleep (80%), and daytime fatigue (72%). A third experienced an increased risk of errors and mistakes. However, QRs appeared to facilitate taking reports from patients and planning work, as this task was more often rated as ‘very easy’ following a QR compared to other shift combinations. Tolerance of QRs varied substantially. In conclusion, QRs seem to benefit continuity in work processes, but may do so at the expense of recovery and safety. Wards planning to reduce QRs –through participatory or fixed schedule models – should consider impacts on work processes.

    Teleworking has been adopted as a response to COVID-19 to reduce the spread of the infection, while continuing business operations. Saudi Arabia was among the countries that adopted stringent teleworking policies accompanying the first documented COVID-19 case. A descriptive, cross-sectional study was conducted to explore experiences of employees towards teleworking as a mandated work setting during COVID-19 in Saudi Arabia. We collected data using a questionnaire that was disseminated via different social media platforms during the partial curfew in the Country. The study sample included 471 participants. Most participants (78%) were satisfied with teleworking and reported higher job efficiency (44%) and work concentration (48%), and better work-life balance (56%) and stress management (55%). The positive experience was dependent on factors, such as gender, age, marital status, educational level, working sector and teleworking mode. Men, bachelor’s degree holders, nonmarried, and employees working in health and education sectors as well as working flexible hours had less positive experience than their respective counterparts. The research contributes to literature about teleworking as a legitimate alternative work arrangement, while approaching teleworking as a means to reduce risks. As the first study conducted within Saudi Arabia, the study’s findings have implications for policy, practice and research.

    This study aimed todetermine the effect of physiotherapists’ physical burden caused by different bedheights during manual therapy. Thirty-three male physiotherapists performedtasks simulating lumbar massage and passive hip abduction range-of-motionexercise (ROM) on the beds with low height (LH) and adjusted height (AH), witheach task performed three times. The anterior inclination angle of thephysiotherapist’s trunk was measured, the surface electromyograms of theerector spinae and trapezius muscles were recorded, and perceived stress wasassessed. The indexes obtained were statistically compared for different bedheights. Additionally, the lumbar disc compression force and flexion torquewere estimated. The lumbar burden caused by the excessive bending and thebiomechanical burden and perceived stress were stronger at LH than AH. In ROM tasks using the right hand, the muscleactivity was lower at the left lumbar region at LH than at AH. At LH, the anteriorinclination angle increased and the lumbar muscle activity declined as the numberof tasks increased. The burden on the shoulders was not significantly differentby bed heights. Our results showed that, when physiotherapists perform manualtherapy, it is necessary to adjust the bed height to reduce physicalburden and ensure higher quality of service.

    When using a local exhaust hood to remove harmful substances from the production process, the exhaust airflow rate must be calculated according to the capturing velocity specified by the relevant regulations. The Numano and ACGIH equations are used in Japan and the US, respectively, for estimating the exhaust airflow rate of slot hoods. However, these equations differ from each other, and when using these equations to calculate the exhaust airflow rate of the capture hood, whether using Japan’s equation or ACGIH, the hood type (slot or rectangular hood) should be distinguished at first. Therefore, this study performs experiments and a CFD simulation to investigate the relationship between the centerline velocity and the aspect ratio for five types of capture hoods. The results showed good agreement between simulated and experimental centerline velocities when the distance from the hood face. A dimensionless velocity was introduced and a significant difference in the relationship between the centerline velocity and the distance from the hood face with different aspect ratios was found. A unified equation was obtained that can express the relationship between exhaust airflow rate and centerline velocity regardless of the aspect ratio of the hood face of the free-standing capture hood.

    We aimed to systematically review and meta-analyze the association of employees working in various kinds of open-plan offices with sick leave data, compared to those working in traditional cell offices. Databases of PubMed, PubPsych, and Psyndex were systematically searched following the PRISMA statement. Pooled summary estimates of odds ratio (OR) were calculated comparing sick leave of employees in cell offices with those working in small open-plan offices (4–9 people), and those in various open-plan office solutions (≥ 4 people). We used Forest plots visualizing study-specific estimates and the pooled fixed and random effects estimators. Five studies were identified (2008–2020) with a total of 13,277 (range 469–6,328) participants. Compared with employees working in cell offices, those working in small open-plan offices were associated with higher odds of sick leave days (OR=1.27; 95% CI 0.99–1.54; p=0.046) as well as those working in various kinds of open-plan offices with ≥ 4 colleagues (OR=1.24; 95% CI 0.96–1.51; p=0.004). Our results are consistent with those of earlier reviews focusing on other effects of open-plan office solutions such as health and well-being. Different solutions for office design and architectural lay-out should be the focus of future studies to balance pros and cons of open-plan offices.

    The present study analyses the effect of jobcontrol at work on psychological stress for Indian Middle-Level Managers (MLMs)of a public telecom organisation. 210 MLMs from different parts of India haveparticipated in the survey. Three dimensions of job control visualize controlover work (CoW), control overworking time (CoT1) and control over working days (CoT2), were considered. The validity and reliability were confirmedusing Factor and reliability analysis. A Binary Logistics Regression (BLR) wasperformed to find the effect of job control on behavioural, somatic and cognitive stresscontrolling for age, gender, and experience. The Odds Ratio andAdjusted Odds ratio were calculated. 56% of the participants reported sufferingfrom psychological stress. Results showed that CoT1 had a significantassociation with somatic stress while CoT1 and CoT2 with cognitive stress. LowCoW and low CoT2 were associated with high psychological stress amongmiddle-level managers while low CoT1 to low psychological stress. The findingsindicate that job control have both positive and negative relationships withpsychological well-being depending on its dimension. Increasing job controlcannot entirely ensure the psychological well-being of employees. Therefore, organisations need to assessdifferent dimensions of job control carefully before providing work flexibilityto employees.

    Return to Work (RTW) programmes have become imperative in manpower scarce countries. This paper describes a RTW programme in a Singapore tertiary hospital, reports patient outcomes and discusses the practicality and effectiveness of the programme. Seventy-three workers participated in the programme over a two-year period. A statistically significant increase in work ability and self-perceived overall health status from first contact with worker (baseline) to discharge was observed. Continued programme participation till first RTW was associated with higher work ability and self-perceived overall health status at baseline. The RTW Coordinator-anchored multidisciplinary model which provided holistic support to the worker and addressed stakeholder interests were central to the programme’s success. Greater awareness of RTW programme benefits will improve sustained participation. Our RTW programme features, implementation experiences and participant reported effectiveness may inform the development of improved return to work models.

    Female nurses experience work-family conflict due to performing multiple roles, leading to burnout. Thus, this study aimed to verify the association between burnout and the multiple work and family roles performed among Japanese female nurses. The data for 2,255 nurses at 23 Japanese hospitals obtained from the Work Environment for Nurses Study in Japan were used. The variables included burnout, demographic information, additional work roles, and child-rearing or caregiving. Half of the nurses were categorized under the “no-role” group (NRG), approximately a quarter under the “work-role” group (WRG), 16% under the “family-role” group (FRG), and 7.3% under the “multiple-role” group (MRG). Compared to the NRG, the FRG and MRG showed statistically lower emotional exhaustion (B=−0.79, p<0.05; B=−0.94, p<0.05, respectively) and depersonalization (B=−0.80, p<0.05; B=−1.09, p<0.05, respectively). Personal accomplishment was not statistically different among the four groups. Burnout was relatively low among nurses with family roles, suggesting that family roles may have a positive spillover effect on work-related emotions.

    To evaluate whetherfinancial aid for acupuncture therapy is beneficial for non-manufacturing jobworkers (office workers) who are aware of reduced job performance due to healthissues (presenteeism), a four-week pragmatic multicenter randomized study was conductedwith office workers who were aware of their presenteeism. The control group onlyimplemented the workplace-recommended presenteeism measures, whereas theintervention group received financial aid for acupuncture therapy of up to 8,000 JPY in addition to implementing the presenteeismmeasures recommended by each workplace. The major outcome measure was the WorldHealth Organization Health and Work Performance Questionnaire relativepresenteeism score. A total of 203 patients were assigned to the intervention(n=103) and control (n=108) groups. The intervention group underwent a medianof 1.0 (interquartile range [IQR], 1.0 to 2.0) sessions of acupuncture for neckdisorders (64%), back disorders (16%), and depressed mood/anxiety/irritation (5%),among others. Results showed that the intervention group had slightly better jobperformance than the control group (effect size [r] = 0.15, p=0.03).Financial aid for acupuncture therapy may help compensate for losses incurredby enterprises in the form of 14,117 JPY per worker a month.

    This study evaluated the differences in respiratory protection between replaceable particulate respirators (RPRs) and powered air-purifying respirators (PAPRs) based on different wearing methods during exercise tasks. Ten participants wore RPRs and PAPRs alternately in ways comparable to those adopted by workers in actual workplaces. We measured the fit factor of the respiratory protective equipment (RPE) during exercise tasks for each wearing variation. The exercise load was set to 80W using an ergometer. The exercise tasks comprised five actions described in the Japan Industrial Standard T8150 in 2018. We compared the results with experimental data obtained at rest in our previous studies. The fit factor of RPRs during exercise was significantly lower than (p<0.001) and about half that measured at rest, indicating inadequate respiratory protection. On the other hand, the fit factor of PAPRs during exercise tasks was also significantly lower than (p<0.001) and about half that at rest, but respiratory protection was maintained. This suggests that the protection provided by PAPRs is independent of wearing method during exercise. PAPRs may thus be better than RPRs for workers who have to wear RPE inappropriately due to health problems.

    The amount of asbestos body (AB) in the human lungs is used as an index to assess asbestos lung cancer (ALC). This study reports a new method to observe the same AB previously observed by analytical transmission electron microscope (ATEM) by phase contrast microscope (PCM). Four kinds of specimens were prepared from the lung tissue of an asbestos related worker: ordinary PCM specimen (A); PCM specimen (B) of which the cover glass was stripped off and ashed at a low temperature; transmission electron microscope (TEM) specimen (C); and PCM specimen (D) covered a TEM specimen (C) with immersion liquid and cover glass. These specimens were all observed by PCM, and the specimen (C) by analytical TEM (ATEM). The results showed that the TEM specimen (C) is transparent in visible light and we can also see the particles by PCM. The image by PCM of the TEM specimen (C) showed very similar features to that of PCM specimens (A) and (B). Accordingly, we could observe various same particles by both ATEM and PCM. In conclusion, the method observing the same AB by both PCM and ATEM will contribute to standardize the recognition of AB by PCM analysts.

    An imbalance in the keyorganizational psychology constructs viz. “Workload”, “Reward”, “Community”,“Control”, “Values” and “Fairness” are potential factors leading to negativeoccupational mental health, i.e. burnout. Burnout, a psychological syndrome is thecombination of emotional exhaustion, sense of reduced compassion andaccomplishment. To note, the concept of occupational mental health in a nationwith second largest workforce is nascent. Further, the utility of existingwestern tools in Indian subcontinent is limited by culturallyinappropriateness, patented, less comprehensible and other factors. Presentstudy attempted to develop tools to screen occupational mental health andworkplace areas. Conventional steps involved in psychological tool development,viz. construct identification, drafting of pertinent questions, contentvalidation, field testing of questions and others were adopted. After series ofsteps, tools for screening occupational mental health and key constructsinfluencing mental health at workplace (workplace assessment) were developed.The screening tools exhibited adequate test - retest reliability, internalconsistency / reliability (cronbach’s α>0.73) and correlation (correlationcoefficient > 0.6) with the general mental health in larger evaluation of 153consenting workers. The proposed simple and easy to administer tool requiresdevelopment of normative scores thereby aiding early diagnosis and managementof those requiring intervention.

    Since the turn of the millennium, the information technology (IT) industry has been growing rapidly in mainland China. One of the significant characteristics of IT employees in mainland China during the past decades was that they tended to work more overtime, which might result in more work-family conflicts and higher turnover rates. Our study tested the mechanism of work-family conflict and work withdrawal behaviors using data from 389 IT employees in mainland China. Using the job demands-resources model and the conservation of resources theory, we examined the mediating effect of emotional exhaustion and the moderating effect of job autonomy. The results indicated that work-to-family conflict was negatively related with work withdrawal behaviors, whereas family-to-work conflict was positively related with work withdrawal behaviors. Moreover, we found the opposite moderating role of job autonomy, which enhanced the relationships between emotional exhaustion and work withdrawal behaviors. That is, the relationship was stronger among employees with higher job autonomy than among those with lower job autonomy. These findings indicate that work-family conflict relates to employees’ psychological well-being and behavior, and that job autonomy might play a special role between work-family conflict and work withdrawal behaviors.

    N95 masks filter 95% of the small particles and respiratory droplets (>0.3 µm diameter). Therefore, they are widely used both by general public and health workers during pandemic. When physical activity or exercise is performed wearing N95 mask, it induces hypercapnic environment. The heat burden is also increased leading to discomfort and reduced compliance. This study was done to compare physiological effects and subjective perceptions while wearing N95 mask and powered air-purifying respirator (PAPR) (2 fans, N95 filter) during incremental exercise. ECG, respiratory movement, SpO2, temperature inside the mask were recorded and perception of discomfort was also assessed. Heart rate variability (HRV) values during baseline were within normal limits in both the mask conditions signifying that cardiac autonomic tone is comparable. During incremental exercise, fall in SpO2 was significantly lesser in PAPR as compared to N95 mask at 60–70% and 70–80% of maximum achievable heart rate. The temperatures inside both the mask conditions were significantly higher than ambient temperature. The scores of humid, hot, breath resistance and fatigue were significantly lower in PAPR than N95 mask. In conditions where prolonged use of mask is required with strenuous physical exertion or exercise, PAPR could be preferred over N95 mask.

    The rate of industrial accidents in Korea is two to three times higher than those in advanced countries such as Germany. These accidents are mainly concentrated in high-risk industrial areas. Using the ninth wave of the Occupational Safety and Health Company Survey by the Occupational Safety and Health Research Institute (OSHRI), we analyzed the influence of corporate culture on the occurrence of occupational accidents in high-risk industries using negative binomial regression. We found that older workers and foreign workers had a positive effect on the accident rate, while female workers had a negative effect on the accident rate. In addition, it was found that the health and safety management organization also reduced occupational accidents. Corporate culture and workplace environment significantly reduced industrial accidents among workers. This suggests that internal elements of an organization such as corporate culture and working environment can have an impact in reducing the occurrence of industrial accidents.

    Sickness absences are a significant public health and economic problem worldwide. However, sickness absence diagnoses and trends have not been reported in much detail in Japan. This study was a retrospective cohort study. We examined data on certified diagnoses and the durations of sickness absence lasting over 90 days (long-term sickness absence) from 2009–2018 among city public servants in Japan. We found that 1) “Mental and behavioral disorders” (495.0–780.6 per 100,000 employees) was the most prevalent reason for long-term sickness absence, and “Mood disorders” (318.6–584.3 per 100,000 employees) was the most prevalent mental disorders diagnosis in each study year; 2) the prevalence of long-term sickness absence for mental disorders showed decreasing trends (781/100,000 in 2009 to 622/100,000 in 2018; [p=0.005, for the trend test]); 3) the trends differed by gender (p<0.05) and age (p<0.001); and 4) the duration of long-term sickness absence related to mental disorders (13.2 ± 9.0 months) was longer than long-term sickness absence resulting from all physical disorders except for diseases of the circulatory system (15.1 ± 11.6 months). Increased focus on significant depressive and neurotic disorders is needed when promoting mental health in the workplace.

    In this study, we aimed to determine whether 21-hour continuous wakefulness decreases performance in the Iowa Gambling Task and examine the effect of the interaction between a weak emotional stressor and prolonged continuous wakefulness on the decision-making process, as measured by the Iowa Gambling Task. Approximately half of 38 healthy college students were in the sleep deprivation condition (they performed the task at 4:30 a.m.); the remainder were in the daytime condition (they performed the task during the day). The participants in each sleep condition were further divided into non-exposed and exposed to an emotional stressor via a social exclusion procedure before the task, with the Iowa Gambling Task score as the dependent variable. In the sleep deprivation condition, performance in the final block of the task was significantly worse in the group with an emotional stressor than the group without. There was no main effect of sleep conditions or emotional stressors on the task performance in either block. The results of this study suggest that even 21 hours of continuous wakefulness, which can occur in daily work life, may prevent appropriate learning in people exposed to an emotional stressor, even if the stress caused due to it is low.

    To clarify the combined effect of the sub-factors of organizational commitment, this study examined the relationships between organizational commitment profiles and work engagement, psychological distress, and turnover intention among nurses. A cross-sectional survey was conducted; 455 nurses (38 men and 417 women) were included in the statistical analysis. We extracted six clusters through k-means cluster analysis and applied a one-way analysis of variance and chi-square test for work engagement, psychological distress, and turnover intention. Consequently, significant differences were found in work engagement and turnover intention (both p <0.05), and no significant difference was found in psychological distress. These results indicate the formation of affective and normative commitment among nurses in working energetically or preventing turnover. Additionally, no negative effects related to increases in continuance commitment were identified in this study.

    There is a drive to support workers in Japan undergoing medical treatment who wish to continue working, known as the work–treatment balance. This support for the work–treatment balance is expected to boost their mental health. This study examines the relationship among the work–treatment balance, job stress, and work engagement. This study was conducted in December 2020 in Japan, with 27,036 participants. We divided the participants into three groups by the receipt state of support for work–treatment balance: control group (do not need support), unsupported group, and supported group. The scores on the parameters of the job content questionnaire and the Utrecht Work Engagement Scale (UWES-3) were compared among groups using a multilevel regression with age-sex or multivariate-adjusted models. In the two models, the job control score of the unsupported group was significantly lower than that of the control group. The two social support scores of the supported group were significantly higher than those of the control group. The scores on the UWES-3 of the unsupported group were significantly lower than those of the control group. The support of work–treatment balance for workers could have a positive impact on their mental health.

    Occupational safety and health management expense (OSHE) in construction industry is a statutory expense used for the purpose of preventing occupational accident and health disorders for construction workers, and the detailed usage standard is stipulated in the law and regulations governed by the Ministry of Employment and Labor in Korea. Previous studies focused on improvement of the accounting rate of OSHE and institutional improvement to secure usage transparency, but analysis showed that the review of improvement directions for usage items was insufficient. Considering recent trends, such as the increase in industrial demand to improve existing usage items and the introduction of various smart safety products incorporating the Fourth Industrial Revolution technology, it is expected that it will be necessary to review ways to improve the usage items to enhance the operational efficiency of OSHE. Accordingly, this study collected opinions from various stakeholders, and presented a roadmap to improve usage items of OSHE through importance-performance analysis (IPA) based on the data. This study is expected to meet the needs demanded by industry, and to be utilized as a reference for policy preparation to enhance the safety of construction sites.

    The present study investigated the role of job/home resources in the relation between job/home demands and exhaustion, job satisfaction, work-home interference, and home-work interference during the COVID-19 pandemic. We explored the prevalence of job/home demands and resources during the COVID-19 pandemic, and examined whether working at different locations (i.e., working from home or at the office) affects how both job/home demands and resources are associated with employees’ health and well-being. An online cross-sectional survey study using self-report questionnaires was carried out among the networks of the International Commission on Occupational Health (ICOH) association (N=153). The findings of this study illustrated that (1) cognitive job demands/resources and emotional home demands/resources were crucial in predicting employee health and well-being; (2) a conceptual match was detected between corresponding demands and resources; (3) subgroup analysis showed that employees were not heavily affected by the different working locations during the pandemic. In conclusion, this study confirms the positive role of job/home resources. We suggest that cultivating specific job/home resources and establishing an appropriate match between specific job/home resources and corresponding job/home demands is necessary to ensure employees’ health and well-being in times of a pandemic.

    Interpersonal conflicts at workplace are increasing in relation to high competitiveness and pressures at work, mainly connected with labor market globalization. Their manifestation is multifaceted in relation to different working conditions and they not only hinder health, performance, and job satisfaction, but can also harm people's rights and dignity. The study analyses issues related to work conflicts and adverse health consequences in 1,493 workers who approached a hospital service for work-related stress and harassment over a 3-year period. The subjects were examined according to a broad protocol covering working conditions, sources of conflict and negative actions suffered, and resulting impact on health status. Many critical conditions were reported in all occupational sectors with some differentiation in relation to gender (women more at risk) and employment status. Higher qualified levels were more exposed to experiencing severe personal adversities aimed at their progressive expulsion or resignation, with consequent higher risk of chronic adjustment disorders, while lower levels reported more stressful conditions in terms of interpersonal disputes and greater interference in the home-work interface. The study can provide useful indications for a better understanding of workplace conflicts in order to set up the most appropriate actions to manage and prevent them.

    Among the reports on needlestick and sharps injuries (NSIs), many are orthopedic-related due to the frequent use of sharp devices such as pins and wires. This study aimed to identify high-risk instruments, the most common injury sites for each instrument, and the circumstances of NSIs of the hand during orthopedic surgeries in Japan. Incidents of exposure to blood or bodily fluids among physicians during orthopedic surgeries reported to the Japan EPINet between 2000 and 2015 were included in this study. The four most common devices were identified and the associations among years of experience, equipment users, and injured sites were analyzed. We identified 666 cases of NSIs affecting orthopedic surgeons in the operating room. The instrument most frequently responsible for NSIs was suture needles, which were involved in 265 cases (39.7%). The second most common instrument was pins/wires, which was involved in 111 cases (16.6%). NSIs of the hands of orthopedic surgeons were frequently caused by suture needles used in all surgeries, but relatively often caused by orthopedic devices. Orthopedic surgeons must be aware that they are at risk of NSIs and must take appropriate measures and always be cautious when performing surgery, regardless of their years of experience.

    Gig work is a type of contingent work which has increased markedly in recent times, and is characterised by uncertainty, unpredictability, and instability of both schedules and income earned. Gig workers are also likely to work for multiple platforms and/or employers. These work characteristics mean that performing gig work is associated with higher rates of stress than the general population1). However, it is not currently known which strategies gig workers use to cope with this stress – including which strategies are likely to be effective. The aim of this study was to understand the relationship between coping strategies, number of employers and stress in gig workers. An online survey was completed by 49 gig workers. Validated questionnaires were administered to measure coping strategies (Brief COPE) and stress (Perceived Stress Scale-14). Approach coping strategies (active, planning, and social support) were associated with reduced stress (p<0.05), whereas the avoidant coping strategy of self-blame was associated with increased stress (p<0.05). No differences in stress were seen between gig workers with one employer and those with multiple employers. Findings suggest that some coping strategies may lower stress in gig workers, though long-term outcomes should be considered in future research.

    The association between oral diseases and work productivity loss remains unclear. This study examined whether dental caries, tooth loss, and poor periodontal status were associated with absenteeism and presenteeism. This cross-sectional study used two independent datasets: 184 employees at a medical university and 435 employees from among the registrants of an online research company. Absenteeism and presenteeism, according to the World Health Organization Health and Work Performance Questionnaire, were dependent variables. The independent variables were the number of decayed and filled teeth (DFT), missing teeth (MT), and self-reported periodontal status. Multivariable linear regression models were developed to estimate unstandardised coefficients with 95% confidence intervals (CIs) for absenteeism and presenteeism. After adjusting for covariates, among the 435 employees enrolled from among the registrants of an online research company, poor periodontal status was significantly associated with a 7.8% (95%CI = −14.5, −1.0) decline in presenteeism but not absenteeism. DFT and MT were not significantly associated with either absenteeism or presenteeism in both populations. Given that periodontal status was potentially associated with a 7.8% decline in work performance, occupational specialists, managers, and dental health professionals should be aware of the impact on work productivity.

    In shift work disorder (SWD), disturbed sleep acutely impairs employees’ recovery, but little attention has been paid to sleep during longer recovery periods. We examined how holidays affect self-estimated sleep length, sleep debt, and recovery in cases of SWD. Twenty-one shift workers with questionnaire-based SWD and nine reference cases without SWD symptoms completed a questionnaire on recovery and sleep need. They also reported sleep length on two separate occasions: during a work period and after ≥ 2 weeks of holidays. Sleep debt was calculated by subtracting sleep length from sleep need. We used parametric tests to compare the groups and the periods. The groups reported shorter sleep on workdays than during holidays (median difference: SWD group 1.7 h, p<0.001; reference group 1.5 h; p<0.05). The SWD group’s self-estimated sleep during holidays increased less above the sleep need (median 0.0 h) than the reference group’s sleep (1.0 h, p<0.05). In addition, the SWD group reported good recovery from irregular working hours less often (14%) than the reference group (100%, p<0.001). Although holidays were generally associated with longer sleep estimates than workdays, employees with SWD experienced consistently less efficient recovery than those without SWD.

    Australian’s cocaine use is at record levels. Large increases occurred between 2016–2019, with significant increases predominately found among employed Australians. Patterns, and prevalence of workers’ cocaine use were examined using the 2016 and 2019 National Drug Strategy Household Survey data via frequency analyses. Logistic regression modelling identified predictors of employed Australian’s: cocaine use (2019); and increased use over time (2016–2019). Workers’ cocaine use increased 63% between 2016–2019 (3.8%–6.2%). Predictors of use, and increased use, were age, marital status, state, remoteness, smoking status, alcohol use, and cocaine approval level. Income and psychological distress predicted cocaine use in 2019 only. Highest prevalence in 2019 occurred among workers who approved of regular cocaine use (47.9%), currently smoked (14.9%), were very highly distressed (14.0%), risky alcohol consumers (13.7%), and aged 18–24 years (13.9%). Numerous individual-level characteristics influence workers’ cocaine use. Workplace cultural norms and substance use climates may facilitate increased cocaine use. The workplace is a powerful setting for cocaine prevention and intervention efforts. Potential strategies include targeting social norms, shifting positive drug use workplace cultures, and providing health and safety training focussing on the risk of use to self and co-workers whilst also examining demographic subgroups’ motivations for use.

    Individuals with high levels of autistic traits are at a high risk of experiencing depressive symptoms, and are also vulnerable to job stress. This study aimed to identify which combination of autistic traits and type of job stress are related to depressive symptoms. Participants comprised 992 workers from different regions of Japan. Autistic traits, depressive symptoms, and job stress were measured using the Autism-Spectrum Quotient, K6 scale, and Job Content Questionnaire, respectively. Logistic regression was performed to estimate the odds ratio and 95% confidence interval. Workers with high autistic traits scores reported significantly more depressive symptoms for all job stress types, especially high job demand. Depressive symptoms differed according to autistic traits and job stress. In workers with high autistic trait subscale scores, those with active job stress reported more depressive symptoms than those with high strain job stress, except for the “poor imagination” trait. This is contrary to previous reports that the active stress type is generally less associated with depressive symptoms than the high-strain stress type. To prevent depressive symptoms in workers with high autistic trait scores, it is important to understand which combination of autistic traits and type of job stress contribute to depressive symptoms.

    This study aimed to identify the major industries and jobs with the highest proportion of workers’ compensation (WC) claims for COVID-19, characterize COVID-19 WC claims in terms of their demographic properties and disease severity, and identify factors influencing the approval of COVID-19 WC claims as occupational disease. A total of 488 workers who submitted COVID-19-related claims to the Korea Workers’ Compensation and Welfare Service (KWCWS) from January 2020 to July 2021 were analyzed. A Fisher’s exact test was employed to associate the severity of COVID-19 infection with demographic properties. The highest proportion of all COVID-19 WC claims compensated as occupational disease (N=462) were submitted by healthcare workers (HCW=233, 50%), while only 9% (N=41) of the total originated from manufacturing industries. The 5% (N=26) of the COVID-19 WC claims accepted were evaluated as severe (N=15) and acute respiratory distress syndrome (N=9). A total of 71% (N=329) of the COVID-19 patients compensated (N=462) were from workplaces with infection clusters. A total of 26 WC cases were rejected for various reasons, including unclear infection routes, infection at private gatherings (including within families), no diagnosis, and more. Given our findings, we suggest an official system should be established to detect and compensate more job-associated infectious diseases like COVID-19.

    Previous studies have shown that shift workers are more prone to non-communicable diseases. The aim of the present crossover study is to investigate whether it is possible to improve the health status of shift workers. Nineteen male shift workers (38.5 years ± 7.4) received every other month a dietary counseling for one year. All subjects kept a seven-day diet diary during a night shift, received bioelectrical impedance analysis, and a laboratory examination was performed at the beginning of the study, after one year and at the end of the study. The laboratory blood test included the main metabolic parameters, melatonin and serotonin. Beside subjects were also motivated to incorporate more physical training into their daily routine. After the intervention period, participants reduced energy intake, mean portion size, table salt, consumption of sugar and saturated fat. C-reactive protein (CRP), mean corpuscular volume (MCV), liver enzymes, triglycerides, and uric acid decreased, while melatonin level increased. Participants lost body weight and reduced waist circumference after the intervention. Lifestyle modification and dietary information could contribute to the health of shift workers. However, further studies are needed to investigate whether this can prevent disease and whether melatonin production can be influenced by diet.

    Sedentary behavior at work contributes to detrimental cognitive outcomes (e.g., decreases in attention). The length of time that cognitive performance benefits are sustained following bouts of breaking up sitting (e.g., using sit-stand desks or walking) is not known. A narrative review of the literature was conducted using a systematic search strategy, with keywords related to breaking up sitting interventions in office-based environments and cognitive performance outcomes in the period immediately post the cessation of the breaking up sitting intervention. Three types of office-based breaking up sitting interventions were identified; 1) sit-stand desks, 2) walking desks and 3) cycling desks. From the eight studies which met the criteria, the impacts of these interventions on cognitive performance outcomes were mixed, with significant benefits in some studies and others reporting no benefit. Of the cognitive domains assessed, working memory, attention, and psychomotor function showed significant sustained improvement for up to 30 minutes post intervention. While there are benefits to a key set of cognitive performance domains following breaking up sitting interventions in office-based settings, no studies have evaluated whether benefits to cognitive performance persist for longer than 30 minutes after the breaking up sitting intervention. Furthermore, specific applications of these cognitive benefits to tasks outside of work (e.g., driving home from work) are unknown.

    This study examines the effects of short sleep duration (SSD) on hemodynamic and psychological responses under long working hours (LWH) in a laboratory experiment. Sixteen subjects participated in a crossover design experiment consisting of two conditions: normal (7-hours) sleep and short (5-hours) sleep. In each condition, participants engaged in simulated LWH (13 hours a day), comprising 12 task sessions. Hemodynamic and psychological responses were measured in each session. Results showed that there were significant main effects of condition and session but no interaction for hemodynamic and psychological responses. Systolic blood pressure and fatigue were higher in the later sessions than the first one. Stroke volume, sleepiness, fatigue, and stress were higher in the 5-hour than the 7-hour sleep condition (all p<0.05). These results suggest that although the combined effect of LWH and SSD was not significant, both LWH and SSD caused a hemodynamic and psychological burden.

    The types of workplaces and occupations with coronavirus 2019 (COVID-19) clusters vary between countries and periods. We aimed to characterize major occupational groups with mass outbreaks of COVID-19 infections in several Asia-Pacific countries. Data on the major occupations or workplaces reporting COVID-19 cases in workplaces from January 2020 to July 2021 was collected from industrial hygiene professionals in nine countries. The proportion of workers accounted for 39.1 to 56.6% of the population in each country. The number of workers covered in the national statistics varies among nations based on their definition of a worker. None of the countries examined here have systematically collected occupational data on COVID-19 illnesses and deaths classified by type of industry, occupation, or job. Most countries experienced COVID-19 clusters among health and social care workers (HSCW) in hospitals or long-term care facilities. The types of occupations or workplaces with virus clusters in some participating countries included prisons, call centers, workplaces employing immigrants, garment facilities, grocery stores, and the military, which differed among countries, except for a few common occupations such as HSCW and those populated by immigrants. Further study is necessary in order to seek ways to control infection risks, including revisions to industrial-health-related laws.

    The scientific literature about presenteeism among farm workers is scarce. This study estimated the prevalence of and factors associated with presenteeism among paid fruit farm workers. A cross-sectional study investigated 340 paid employees of both sexes, aged 18 years or above, who worked during the 2019 irrigated fruit harvest in the municipality of Petrolina, Northeast Brazil. Information about sociodemographic characteristics, lifestyle, general health status, occupational characteristics, interpersonal work aspects, and the work environment’s structural characteristics was collected in a structured questionnaire. Presenteeism was established when participants reported working one or more days during the previous season despite feeling ill or when injured. Cox regression was used to estimate prevalence ratios adjusted by sex, area of residence (urban or rural), employment contract (permanent or seasonal), satisfaction with management, participation in workplace decision-making, availability of on-site healthcare facilities, and on-site availability of sunscreen. The prevalence of presenteeism during the previous season was high: 58.2%. In the final multivariate model, the adjusted prevalence ratio was higher (≥1.20) among female workers (1.42), workers dissatisfied with management (1.28), and those for whom sunscreen was not available on site (1.61). The prevalence of presenteeism was high and associated with personal, work organizational, and workplace resources characteristics.

    In Taiwan, over 80% of home caregivers have experienced musculoskeletal disorders (MSD) in the past year. Although MSDs in health care workers have been discussed in existing literature (e.g., in nursing staff), there is limited understanding of the association between MSD and the work content of home caregivers. This study aimed to investigate the correlation between the work content and MSD of home caregivers. This cross-sectional study was conducted in long-term care units in central Taiwan. A structured questionnaire was used to collect data, including basic information, work content survey, and information from the Nordic Musculoskeletal Questionnaire. Logistic regression analysis was used to examine the association between work content and MSD. A total of 149 home caregivers with a mean age of approximately 50.97 ± 9.80 years were recruited for the study. The frequency of transfer of toilet and wheelchair was significantly associated with shoulder discomfort, upper back discomfort, and wrists/hands discomfort. In addition, the frequency of passive range of motion exercise was significantly associated with elbows discomfort. The results of this study indicated that the highest risk factor for MSD was transfer of toilet and wheelchair followed by passive range of motion exercise.

    Potential insomnia in healthcare workers is a public health concern as it may degrade the quality of patient care. We examined the prevalence of insomnia symptoms in healthcare workers and their perceived need for a sleep intervention. Participants were 62 nurses working full-time at a U.S. hospital. These nurses were asked about background characteristics, perceived stress, sleep concerns, and need for a sleep intervention. They also participated in 14-day ecological momentary assessment (EMA) and actigraphy sleep study. A qualitative analysis showed that the majority (92%) of participants reported at least one sleep concern with insomnia-related concerns being most prevalent (68%). Quantitative analyses indicated that those with insomnia-related concerns had higher perceived stress overall and lower EMA sleep sufficiency and sleep quality. Moreover, participants with insomnia concerns had shorter actigraphy-measured nap duration prior to non-workdays than those without. Nearly all (95%) expressed interest in participating in a sleep intervention; an online format and mindfulness contents were most preferred. Our results suggest a high prevalence of insomnia symptoms and a high interest in a sleep intervention in nurses. Information obtained from this study could be used to deliver a tailored sleep intervention for nurses whose role in public health is essential.

    This study evaluated whether cold-induced deterioration in neuromuscular function can be restored by intermittently increasing the workload. We examined the level of muscular strain, agonist-antagonist co-activation, the occurrence of EMG gaps and neuromuscular efficiency in wrist flexor and extensor muscles at 21°C (TN) and 4°C (C10) with a 10%MVC workload. During second exposure to 4°C (C50) the workload was increased every fourth minute to 50%MVC. The results indicated that muscular strain and co-activation was the highest and the amount of EMG gaps and neuromuscular efficiency the lowest at C10. By intermittently increasing the workload at C50 we were able to reduce muscular strain and co-activation (p<0.05) and induce a trend like increase in EMG gaps and enhance neuromuscular efficiency in relation to C10 (NS). It may be concluded that intermittently increasing the workload, i.e. breaking the monotonous work cycle was able to partially restore neuromuscular function.

    Leukotrienes (LTs) are involved in the pathogenesis of lung fibrosis and were increased in exhaled breath condensate (EBC) of the patients with pneumoconiosis. However the possible influence of extra-pulmonary disorders on the EBC markers is not known. Therefore in parallel with EBC, LTs’ levels in the plasma and urine were measured in patients with pneumoconiosis (45x asbestos exposure, 37x silica exposure) and in 27 controls. Individual LTs B4, C4, D4 and E4 were measured by liquid chromatography - electrospray ionization - tandem mass spectrometry (LC-ESI-MS/MS). In EBC, LT D4 and LT E4 were increased in both groups of patients (p<0.001 and p<0.05), comparing with the controls. Both LT B4 and cysteinyl LTs were elevated in asbestos-exposed subjects (p<0.05). Asbestosis with more severe radiological signs (s1/s2-t3/u2) and lung functions impairment has shown higher cysteinyl LTs and LT C4 in the EBC (p<0.05) than mild asbestosis (s1/s0-s1/s1). In addition, in the subjects with asbestosis, cysteinyl LTs in EBC correlated with TLC (-0.313, p<0.05) and TLCO/Hb (-0.307, p<0.05), and LT C4 with TLC (-0.358, p<0.05). In pneumoconioses, EBC appears the most useful from the 3 fluids studied.

    Many work activities include hazards to workers, and among these biological risk is particularly important, mostly because of different types of exposure, contact with highly dangerous agents, lack of limit values able to compare all exposures, presence of workers with defective immune systems and therefore more susceptible to the risk. Bioaerosols and dust are considered important vehicles of microganisms at workplaces and interaction with other occupational agents is assumed. Moreover, biological risk can be significant in countries with increasing economic development or particular habits and some biological agents are also classified as carcinogenic to human. Specific emerging biological risks have been recently pointed out by Risk Observatory of the European Agency for Safety and Health at work, and we must consider the worker’s attitude and behaviour, influenced by his own perception of risk more than his real knowledge, that could over-underestimate the risk itself. Therefore, biological risk at work requires a complex approach in relation to risk assessment and risk management, made more difficult due to the wide variety of biological agents, working environments and working techniques that can determine the exposures.
