Abstract: BACKGROUND: Knowledge on long-term participation is scarce for patients with paid employment at the time of stroke. OBJECTIVE: Describe the characteristics and the course of participation (paid employment and overall participation) in patients who did and did not remain in paid employment. METHODS: Patients with paid employment at the time of stroke completed questions on work up to 30 months after starting rehabilitation, and the Utrecht Scale for Evaluation of Rehabilitation-Participation (USER-P, Frequency, Restrictions and Satisfaction scales) up to 24 months. Baseline characteristics of patients with and without paid employment at 30 months were compared using …Fisher’s Exact Tests and Mann-Whitney U Tests. USER-P scores over time were analysed using Linear Mixed Models. RESULTS: Of the 170 included patients (median age 54.2 interquartile range 11.2 years; 40% women) 50.6% reported paid employment at 30 months. Those returning to work reported at baseline more working hours, better quality of life and communication, were more often self-employed and in an office job. The USER-P scores did not change statistically significantly over time. CONCLUSION: About half of the stroke patients remained in paid employment. Optimizing interventions for returning to work and achieving meaningful participation outside of employment seem desirable. Show more

Abstract: BACKGROUND: The recent growth of the aviation industry, which poses significant environmental challenges, has heightened the pressure on the sustainability of airports. Airport sustainability requires a holistic approach that encompasses economic, social, environmental, and operational aspects. In this regard, the United Nations’ 17 Sustainable Development Goals (SDGs) Agenda provides a roadmap for the aviation industry. However, despite recognizing the importance of SDGs, aviation authorities and airports often fail to effectively integrate them into their activities and annual reports. OBJECTIVE: This study aims to evaluate the significance of SDGs for airports and select the airport that prioritizes SDGs the …most using Multi-Criteria Decision Making (MCDM) methodologies. METHODS: This study introduces a novel approach that integrates Step-wise Weight Assessment Ratio Analysis (SWARA) and Weighted Aggregated Sum Product Assessment (WASPAS) methods, which are MCDM techniques, to enhance airport sustainability. The SWARA method is employed to evaluate and assign weights to the SDGs in the context of airports. RESULTS: SDG 8 holds the highest level of significance among the goals concerning airports, while SDG 14 falls outside the scope of airport sustainability aspects. Then, five international airports that have been designated as green airports by aviation authorities and assessment organizations are selected, and the optimal alternative is determined using the WASPAS method, considering the weights obtained through SWARA. CONCLUSION: Dallas/Fort Worth International Airport is the top choice due to its successful implementations and reports aligning with the SDGs. Show more

Abstract: BACKGROUND: The coronavirus disease 2019 (COVID-19) pandemic has led to a change of pedagogical strategies from on-campus to “online” modality (synchronous and asynchronous learning) and may influence the health of university students, including their mental workload. OBJECTIVE: To identify the association between mental workload, perception of musculoskeletal discomfort (MSD), and the level of physical activity of Masters’s students’ online learning due to the pandemic. METHOD: This was a pilot descriptive study with a cross-sectional, quantitative, non-experimental study design. The sample consisted of 20 students. To collect the data, the participants answered a sociodemographic questionnaire, NASA-Task Load …Index, International Physical Activity Questionnaire, and the Nordic Musculoskeletal Questionnaire. RESULTS: The students presented mental workload at medium (45%) and high (55%) levels, with time demands as the most prevalent dimension. In addition, 80% of the students reported experiencing MSD in the last seven days, with the most frequent areas being the neck and lower back. Regarding the level of physical activity, five students had a low level (25%), five students had a medium level (25%), and ten students had a high level (50%) of activity. CONCLUSION: Most of the students (95%) conduct their master's degree along with maintaining a full-time job. Therefore, the adaptive requirements according to “time demands” is a negative factor because of its contribution to mental workload. Especially in addition to students’ perception of musculoskeletal discomfort, organizational aspects would be fundamental to prevent physical and mental health risks. Show more

Abstract: BACKGROUND: Numerous people use computer mice for long hours, especially in offices. Mouse users reported various pains and discomfort. OBJECTIVE: The study aimed to assess three types of most common mice (vertical, traditional, flat) in Iran in terms of their effects on carpal tunnel syndrome, hand discomfort, and usability. METHODS: The Boston Carpal Tunnel Syndrome questionnaire, the Cornell Hand Discomfort Questionnaire (CHDQ), System Usability Scale (SUS), and Workplace Ergonomic Risk Assessment (WERA) scores were used to assess vertical, traditional, and flat mice. In addition, the participant’s hand position was analyzed by observation method. RESULTS: …Most participants had medium carpal tunnel syndrome severity; however, flat mouse users had a higher score, and the difference between mice was insignificant (p  > 0.05). Most mouse users felt discomfort in their small and ring fingers, and the type of mouse significantly affected thumb discomfort level. More flat users felt Pain in the different parts of their hands. The flat mouse has the least SUS score. There was a significant difference between the three mice regarding SUS scores (p  < 0.05). WERA mean values were acceptable for numerous mice. Adopting neutral wrist postures was more common among vertical, flat, and traditional mouse users, respectively; however, the flat mouse users tended to bend their fingers. CONCLUSION: There are differences between vertical and traditional flat mice in terms of ergonomic indicators. Although more studies are needed, it seems that vertical mice are better in some indicators. Show more

Abstract: BACKGROUND: Several heat indices have been developed in industrial health, but each has its limitations. OBJECTIVE: The objective of this article is to determine the validity and applicability of a temperature-humidity index, named Humidex compared with the Standard Wet-Bulb Globe Temperature (WBGT) index (ISO 7243). METHOD: This cross-sectional study was conducted in the summer of 2019, in a tile factory in the west of Iran. 59 measurements were performed in 8 different workstations. Environmental parameters including natural wet bulb temperature (Tnw ), dry bulb temperature (Ta ), globe bulb temperature (Tg ), and heat stress (WBGT) …were measured. Humidex was calculated according to an equation. SPSS software (version 16) was used for data analysis. RESULTS: There was a high correlation between Humidex and WBGT in the estimation of heat stress (R=0.912, P<0.001). The Kappa Coefficient between Humidex and WBGT was 0.298, P=0.001. CONCLUSION: Humidex is highly correlated with WBGT. Humidex can be used instead of the WBGT index, especially in hot and humid environments. Show more

Abstract: BACKGROUND: Violence is common in emergency departments and is also increasing in primary care settings. It is important to research the factors that cause violence to prevent incidents. OBJECTIVE: The aim of this study is to determine the frequency, causes, and effects of violence in the workplace of primary care physicians in a province in Turkey. METHODS: This cross-sectional study was conducted among 303 family physicians working in Family Health Centers. The subjects completed a questionnaire consisting of questions designed to elicit healthcare professionals’ perspectives on violence. The analysis was performed using SPSS 15.0 software, with …p  < 0.05 considered significant. RESULTS: The participants’ mean age was 48.05±6.11. The majority (82%) stated that they had been subjected to violence throughout their professional life. Although the rate of exposure to violence was 56.4% in the previous year, they did not report these incidents to the appropriate authorities. The main reason for failing to report violent acts was “not caring” (40.1%). Respondents who believed “violent incidents should be reported” were under 50 years old (p  = 0.045). The impact of violence on their lives was expressed as “losing interest in their profession” (40.8%). The most commonly cited cause of violence was “educational problems” (74.9%). CONCLUSION: Violence is prevalent in primary healthcare settings. It is suggested that there can be numerous reasons for violence, primarily a lack of education, and its effects, such as professional disengagement, are notable. Measures should be implemented to provide physicians with safe working conditions and reduce the risk of violence. Show more

Abstract: BACKGROUND: Aircraft maintenance technicians (AMTs) have the most difficulty in terms of total workload criteria working in line maintenance. This is a very important problem for the Aircraft Maintenance Organization. A systematic and scientific approach is required for its solution. OBJECTIVE: This study proposes a new Multi-Criteria Decision Making (MCDM) based approach to evaluating the total workloads of AMTs to identify the most challenging AMT tasks in the aircraft maintenance organization. METHODS: A new hybrid MCDM approach is proposed by integrating the Decision-Making Trial and Evaluation Laboratory (DEMATEL) and Technique for Order Preference by Similarity (TOPSIS) …methods to compare AMTs on the basis of workloads according to license categories. The hybrid method proposed in this study evaluates the total workload under three main titles: mental, physical, and environmental workload. RESULTS: Focusing on AMTs working in line maintenance of an aircraft maintenance organization, this study revealed that the most important workload criteria determined by the DEMATEL method are lower back strain, upper back strain, time pressure, and air temperature criteria. The results of the TOPSIS method showed that the license categories of AMTs are sorted according to the workloads as follows: A, B2, B1, and B1 + B2. The AMTs holding a “Category A” license have fewer workloads than the other categories. CONCLUSION: The findings of the study reveal some measures that might allow authorities to minimize the workload of AMTs. In addition, the study contributes to the literature because there are few studies that systematically analyze total workloads by using MCDM methods. Show more

Abstract: BACKGROUND: School servants are professionals involved with cleaning and feeding activities in schools. Exposed to conditions of physical and psychosocial overload at work, they may face situations of morbidity and functional restrictions. OBJECTIVE: To evaluate personal and work characteristics and work ability index (WAI) of school servants in Brazil and test the mediating effect of WAI in the duration of sickness absence. METHODS: 163 Brazilian school servants participated in this cross-sectional study, that including the self-completion of a sociodemographic questionnaire, information about the Work Environment, the Protocol of Psychosocial Risks at Work’s Evaluation, and the Work …Ability Index. Also was collected, in a secondary health database, information about sickness absence. A linear regression model was constructed to identify the predictors of the duration of absence, followed by the analysis of mediation with the Path Analysis method. RESULTS: The study found that the WAI partially mediates the relation of the personal characteristics and the work conditions with the duration of absence of the school servants. The predictors included the organizational aspects of work, mental exhaustion, physical damage, health self-evaluation, availability of personal protective equipment, and the need to assume inadequate postures at work. These predictors explained 33% of the duration of absence and 53% of the WAI of these workers. CONCLUSION: This study indicated that inadequate working conditions and low WAI impact in the sickness absence, increasing by 33% the length of time off work of school servants. Show more

Abstract: BACKGROUND: The workplace accommodation process is often affected by ineffective and inefficient communications and information exchanges among disabled employees and other stakeholders. Information systems (IS) can play a key role in facilitating a more effective and efficient accommodation process since IS has been shown to facilitate business processes and effect positive organizational changes. OBJECTIVE: Since there is little to no research that exists on IS use to facilitate the workplace accommodation process, this paper, as a critical first step, examines how IS have been used in the accommodation process. METHODS: Thirty-six interviews were …conducted with disabled employees from various organizations. Open, axial, and selective coding were part of the analysis. Fuzzy set qualitative comparative analysis was used to identify different levels of IS use based on participants’ descriptions. RESULTS: An IS used in the workplace accommodation process consists of electronic request form, accommodation checklist, special budget, specific role, ancillary service, formal policy and procedure. There are different levels of IS use in the current accommodation process. The high-level IS use often results in a better accommodation performance than the low-level IS use, including high efficiency, high effectiveness, and low emotional tolls. Nevertheless, the high-level IS use often uses a specific, inflexible template as well as disregards human elements in the accommodation process. CONCLUSION: This work provides implications that future IS design should raise awareness of disability and accommodation, account for individual differences, involve multiple stakeholder inputs, as well as address the fundamental social issues in the accommodation process.

Abstract: BACKGROUND: There is need for more knowledge about the relationship between work and cognitive functioning in sick-listed individuals. OBJECTIVE: This study investigated whether the degree of work participation is relevant for recovery of cognitive functioning in sick-listed individuals. METHODS: 177 occupational rehabilitation participants and 70 controls participated in a non-randomised, longitudinal study. Participants completed computerised cognitive tests targeting sustained attention and working memory at start and end of rehabilitation and 3 and 12 months after rehabilitation. The change score performance in attention and memory between start and end, start and 3 months and 12 months was …compared in individuals on sick leave 100–75%, 74–40% and 39–0% (three sick leave groups) of the time in the year after rehabilitation, and a control group not being on sick leave. Fixed effect analysis of covariance adjusting for education and work ability was used. RESULTS: The sick leave group 100–75% had significantly lower score on work ability compared to the other groups at baseline. The main findings indicated that the sick leave group 39–0% improved significantly more in sustained attention compared to the sick leave group 100–75% between start and end of rehabilitation and from start of rehabilitation to 3 and 12 months after. CONCLUSION: The degree of work participation seems relevant to recovery of the cognitive function sustained attention in sick-listed individuals. These findings encourage work rehabilitation clinicians, work consultants and employers to develop RTW plans which take into account that graded employment influence cognitive functioning. Show more

Abstract: BACKGROUND: Because of the continually changing nature of work, workplace spirituality (WPS) has drawn more attention in recent years from studies, organizations, and both public and private sectors. Organizations strive to enhance employee well-being and general job satisfaction while developing a feeling of community inside the workplace through fostering WPS. OBJECTIVE: The study aims to assess the literature on WPS in an attempt to provide a broader perspective on the impact of spirituality in the workplace to strengthen and comprehend how an individual or collective spirituality is integrated and manifested in the workplace. METHODS: The literature …was reviewed between 1994–2022 (including articles published online in 2023) and the deductive method was used. RESULTS: As a new and significant contribution to knowledge in this study, maintaining a work environment of otherworldliness can help to advance work commitment (sympathy, mindfulness, significant work). Human resources practices should consider including care contemplation as an individual development program that results in increased empathy for others to support care and sympathy in the workplace. WPS centers around the humanistic idea of representatives in the work environment regarding how they experience a feeling of association, which means satisfaction and arrangement with the working environment. There are three ways to look at WPS: individual, authoritative, and intuitive. CONCLUSION: This study has a significant contribution to knowledge enhancement and development. Such an approach to the development of a spirituality program within an organization can make a positive contribution to the improvement of business achievement and competitive gain. This model has some implications for organizational management where an internal spirituality program is desired. Future and additional research on model assessment under the same topic is strongly recommended. Show more

Abstract: BACKGROUND: The involvement of Perchloroethylene (PCE) in the development of autoimmune diseases has been reported. However, few studies investigated immunotoxicity in PCE-exposed workers. OBJECTIVE: To study changes in the oxidative stress and cytokine profile of young female dry-cleaning workers exposed to PCE. METHODS: Thirty-eight exposed workers and 38 unexposed controls were recruited. All the participants were young nonsmoker females. Individual interviews were conducted by a physician. Blood samples were collected and hematological tests were performed by an automated Coulter Counter. Plasma PCE levels were determined using gas chromatography/flame ionization detection. Plasma total antioxidant capacity (TAC), Catalase …(CAT), Superoxide dismutase (SOD), and Malondialdehyde (MDA) levels were measured using the colorimetric method. The levels of plasma cytokines interleukin-1β (IL-1β), IL-2, IL-4, IL-6, IL-8, tumor necrosis factor-α (TNF-α) and interferon-γ (IFN-γ) were measured by commercially kits. RESULTS: The levels of plasma PCE averaged 561±96 ng/ml in the exposed group compared with 1.3±0.5 ng/ml in the controls. The hematological tests failed to find abnormalities in the exposed workers. Exposed workers presented significantly increased plasma levels of MDA, SOD and CAT. There were no significant differences between the two groups for level of plasma TAC. Significantly increased plasma IL-1β and TNF-α and decreased IL-2 and IL-8 levels were seen in the exposed workers. There were no significant differences between the two groups for IL-4, IL-6, and IFN-γ. CONCLUSION: PCE exposure resulted in changed cytokine profile in dry-cleaning workers, suggesting the potential immunotoxicity of PCE at low exposure levels. Show more

Abstract: BACKGROUND: Return-to-work (RTW) programs are provided as rehabilitation for people who have taken sick leave from work because of mental health problems. However, methods to present this information to workplaces objectively remain limited. OBJECTIVE: This study aimed to conduct an exploratory investigation of the relationship between duration of sick leave and time variation of words used in RTW programs for depression from textual data collected from electronic medical records as a new evaluation indicator. METHODS: The study subjects were those who had taken sick leave because of major depressive or adjustment disorder and had participated in …an RTW program. The study data comprised demographic characteristics and texts. Textual data were collected from electronic medical records and classified based on the SOAP note. Thereafter, the textual data were quantified into category scores based on a standard text analysis dictionary. A generalized linear mixed model was used for the statistical analysis, with the score for each category (emotional, social, cognitive, perceptual, biological, motivational, relativity, and informal) as the dependent variable and the duration of sick leave, time, and interaction between the duration of sick leave and time as the independent variables. The level of statistical significance was set at 0.05. RESULTS: In total, 42 participants were included in the analysis. The results revealed a significant interaction between the social (p  = 0.001) and emotional (p  = 0.002) categories. CONCLUSION: The findings suggest a relationship between word changes in electronic medical records and the duration of sick leave. Show more

Abstract: BACKGROUND: Mobbing in the workplace is a critical problem affecting healthcare workers’ psychological health and performance. However, there is a lack of data on the relationship between mobbing and depression and a lack of regulations to create a decent working environment. OBJECTIVE: We aimed to determine the frequency of exposure to mobbing and the depression levels that may be related to mobbing among the employees of the Anesthesiology and Reanimation Clinic. METHODS: In this multi-center cross-sectional study, employees were evaluated with Leymann’s Inventory of Psychological Terror scale and the Beck Depression Inventory. …RESULTS: Of the participants, 86.2% stated that they were exposed to mobbing. The presence of mobbing was also associated with the presence of psychological and depressive symptoms. CONCLUSION: The frequency of mobbing was relatively high among Anesthesiology and Reanimation clinic employees. Mobbing exposure was found to be associated with a high level of depression. Institutional and legal precautions should be taken, and awareness of mobbing should be increased to eliminate mobbing and its consequences on healthcare workers. Show more

Abstract: BACKGROUND: Contemporary literature raises serious questions about the inclusion of negatively worded items in the safety climate scale. Despite these reservations, limited efforts have been made to address this shortcoming. OBJECTIVE: The present study aims to adapt and empirically validate the ten-items group-level safety climate scale with the purpose of replacing negatively worded items with positively worded ones after a thorough validation process. The present study is one of the first to propose an empirically validated group-level safety climate scale that uses positive items to measure the safety climate construct. METHODS: Study 1 …was conducted using a sample of 135 participants. Study 2 used a time-lagged approach to validate the scale, with a sample of 173 production workers from six oil and gas organizations in Malaysia. The Partial Least Squares Structural Equation Modeling (PLS-SEM) method was used to test the hypothesized relationships. RESULTS: In Study 1, the results of the exploratory factor analysis showed good reliability for the revised scale. In Study 2, the results of the PLS-SEM analysis demonstrated a positive relationship between safety climate and safety behaviors, thereby validating the revised and translated scale of safety climate. CONCLUSION: The revised safety climate scale will not only improve data quality, but it will also increase response rates. Additionally, the revised scale will assist managers in understanding the true perceptions of safety climate in their organization, regardless of the cultural context in which the scale is used.

Abstract: BACKGROUND: Occupational hearing loss is one of the most common work-related diseases with various risk factors and considerable negative impacts on both physical and mental well-being of affected workers. Occupational noise-induced hearing loss (ONIHL) has a complex interaction with personal, environmental and occupational factors. OBJECTIVE: This study aimed to develop a risk model for ONIHL in workers by identifying risk factors and their interactions. METHODS: The subjects were 605 males in an industrial factory in Arak, Iran. The study took place between 2022 and 2023. The sociodemographic and occupational characteristics were collected by a health technician …using questionnaires and medical records. Hearing status was assessed using audiometry by a qualified audiologist. Hearing loss was analyzed by univariate logistic analysis including age, smoking, medical history, type of occupation, and some workplace hazards. The risk model was generated by logistic regression. RESULTS: Hearing loss in the participants was 44.13% (n  = 267). In univariate logistic analysis, age (OR: 2.93,95% CI: 1.848–4.656), smoking (OR: 1.80, 95% CI: 1.224–2.655), work experience (OR: 1.06, 95% CI: 1.016–1.107), previous exposure to noise (OR: 1.60, 95% CI: 1.112–2.312) or vibration (OR: 1.68, 95% CI: 1.150–2.475) and type of occupation (OR: 2.126, 95% CI: 1.055–4.285) were associated with an increased risk of ONIHL (P  < 0.05). CONCLUSION: It was found that vibration exposure, work experience, previous noise exposure, type of occupation as well as age and smoking significantly affected the likelihood of developing ONIHL. This risk model could help management to prevent ONIHL and enhance application-oriented research on the condition. Show more

Abstract: BACKGROUND: People with long work hours, as evidenced by teachers, were more likely to present health problems that impact their quality of life (QoL). The reduced physical activity (PA) level or higher sedentary behavior in public school teachers was related to obesity. Although PA seems to improve the QoL in other professions, assessing whether the PA level could influence the relationship between workload and QoL in public school teachers is necessary. OBJECTIVE: To analyze whether the high workload was related to worse QoL in teachers considered less active and more active. METHODS: Two …hundred forty-three teachers from public schools participated in this study. The domains of QoL and PA levels were assessed by SF-36 and Baecke questionnaires, respectively. Workload perception was assessed by a Likert scale. Binary logistic regression analyzed the association between high workload and QoL domains in teachers considering the PA level in a model adjusted by confounding factors (i.e., sex, age, and socioeconomic condition). RESULTS: Heavy workload was associated with less chances of having better physical limitation domain of both less and more physically active teachers. Less active teachers with heavy workloads were 53%, 61%, and 56% less likely to have better vitality, social functioning, and mental health, respectively. No such associations were observed in the more physically active teachers. CONCLUSION: Less active teachers with a heavy workload demonstrate lower QoL. Although the PA practice eliminated this relationship, both active and less active teachers with a heavy workload demonstrated lower QoL in physical limitation domain. Show more

Abstract: BACKGROUND: Small-scale industries (SSI) are the global economy’s backbone since most industrial workers are connected. Most of these workers are contractual and temporary without appropriate training. Also, the SSI does not have a standard workplace with an appropriate layout and infrastructure, as they manage with minimum resources. Therefore, the work hazards, i.e., musculoskeletal disorders and fatigue, often go unnoticed as holistic postural risk methodology is still scarce for identifying the awkward postures in SSI. OBJECTIVE: The present study proposes a novel holistic methodology to track and mitigate awkward postural risks in human-physical activities in SSI. To determine the …effectiveness of the proposed methodology, a case study is presented in the South Indian Pump industry, wherein a critical workstation with a complex ergonomic work environment is employed. METHODS: An ergonomic evaluation was conducted empirically and numerically in the workplaces using Digital Human Models. In numerical evaluation, three virtual workspaces have been created to redesign the identified crucial workstation, focusing on ergonomics and workflow. RESULTS: The results obtained from the case study are encouraging for to use of the novel methodology in SSI. The case study reports that the proposed design significantly reduced the REBA score and WISHA lifting index by 6 and 1.20, respectively, without significant investment.
