Abstract: BACKGROUND: Workplace bullying is a serious stressor with devastating short- and long-term consequences. The concept of organizational social capital may provide insights into the interactional and communicative dynamics of the bullying process and opportunities for prevention. OBJECTIVE: This study aimed to explore the association between organizational social capital and being a target or observer of workplace bullying. METHODS: Based on self-reported cross-sectional data from a large representative sample of the Danish working population (n  = 10.037), logistic regression analyses were conducted to explore at the individual level the associations between vertical and horizontal organizational social capital with …being a target or observer of workplace bullying. RESULTS: In the fully adjusted models, low organizational social capital (vertical and horizontal) was associated with significantly increased odds ratios of both self-labelled (vertical: OR = 3.25; CI = 2.34–4.51; horizontal: OR = 3.17; CI = 2.41–4.18) and observed workplace bullying (vertical: OR = 2.09; CI = 1.70–2.56; horizontal: OR = 1.60; CI = 1.35–1.89), when compared with high organizational social capital. CONCLUSIONS: This study supports that characteristics of the psychosocial work environment are of importance in the development of workplace bullying, and provides focus on the importance of self-reported organizational social capital.

Abstract: BACKGROUND: Musculoskeletal Disorders (MSDs) are among the most common occupational disorders in many countries and have an increasing trend. OBJECTIVE: The present study was conducted in order to determine the prevalence rate of MSDs in different body regions and the effect of personal factors on the prevalence rate of MSDs among rubber industry workers. METHODS: This analytical and cross-sectional study was performed on 206 workers of an Iranian rubber factory in 2014. The samples were randomly selected. Data were gathered by means of personal information form, the Nordic Musculoskeletal Questionnaire (NMQ) and the Rapid Entire Body …Assessment (REBA). The results were analyzed using SPSS16; by descriptive and analytical statistics. RESULTS: The mean age and work history of subjects were 34.54±6.36 and 12.34±6.28 years, respectively. The highest prevalence rate of MSDs in the last twelve-months was related to the lower back region with a prevalence rate of 62.1%. Based on logistic regression, a significant correlation was found between MSDs and the final REBA score so that for a one-unit increase in score, the risk or complaint of neck and low back pain increased by 48.5% and 37.1%, respectively. CONCLUSION: Many rubber factory workers experience MSDs especially in the lower back region as a consequence of occupational risk factors. Therefore, detecting the occupational risk factors, work position standards and following ergonomic interventions are highly recommended. Show more

Abstract: BACKGROUND: All Terrain Vehicles on public roadways become major risk factors for the motorists. OBJECTIVE: To compare characteristics of crashes and injury severity related to single vehicle (SV) and multi-vehicle (MV) All-Terrain Vehicle (ATV) roadway crashes in Pennsylvania, USA. METHODS: Data on ATV crashes occurring on public roads during the years 2010–2013 was obtained from the Pennsylvania Department of Transportation (PennDOT) and analyzed. RESULTS: Almost two-thirds of the incidents were single-vehicle incidents. Single-ATV incidents have a greater risk for incapacitating injury to drivers than do multi-vehicle ATV incidents. Other factors that increase risk for …incapacitating injury in SV crashes include being male, being a driver, alcohol/drug involvement, hitting a fixed object, and the incidents in non-daylight hours. For MV ATV incidents, head on and rear-end crashes and drivers who had alcohol/drug involvement were the two major incapacitating injury risk factors. CONCLUSIONS: This study has enabled us to better understand roadway ATV incidents, characteristics of SV and MV ATV crashes, and the incapacitating injury risks in both SV and MV crash incidents. Our study suggests that road safety and public health programs should focus on the users’ knowledge on laws regarding ATV usage on public roadways. Show more

Abstract: BACKGROUND: Some studies have suggested a causal relationship between computer work and the development of musculoskeletal disorders. However, studies considering the use of specific tools to assess workplace ergonomics and psychosocial factors in computer office workers with and without reported musculoskeletal pain are scarce. OBJECTIVE: The aim of this study was to compare the ergonomic, physical, and psychosocial factors in computer office workers with and without reported musculoskeletal pain (MSP). METHODS: Thirty-five computer office workers (aged 18–55 years) participated in the study. The following evaluations were completed: Rapid Upper Limb Assessment (RULA), Rapid Office Strain Assessment …(ROSA), and Maastricht Upper Extremity Questionnaire revised Brazilian Portuguese version (MUEQ-Br revised). Student t -tests were used to make comparisons between groups. RESULTS: The computer office workers were divided into two groups: workers with reported MSP (WMSP, n  = 17) and workers without positive report (WOMSP, n  = 18). Those in the WMSP group showed significantly greater mean values in the total ROSA score (WMSP: 6.71 [CI95% :6.20–7.21] and WOMSP: 5.88 [CI95% :5.37–6.39], p  = 0.01). The WMSP group also showed higher scores in the chair section of the ROSA, workstation of MUEQ-Br revised, and in the upper limb RULA score. The chair height and armrest sections from ROSA showed the higher mean values in workers WMSP compared to workers WOMSP. A positive moderate correlation was observed between ROSA and RULA total scores (R = 0.63, p  < 0.001). CONCLUSION: Our results demonstrated that computer office workers who reported MSP had worse ergonomics indexes for chair workstation and worse physical risk related to upper limb (RULA upper limb section) than workers without pain. However, there were no observed differences in workers with and without MSP regarding work-related psychosocial factors. The results suggest that inadequate workstation conditions, specifically the chair height, arm and back rest, are linked to improper upper limb postures and that these factors are contributing to MSP in computer office workers.

Abstract: BACKGROUND: Dentists have a high prevalence of musculoskeletal (MS) pain, which is the most common symptom associated with work-related musculoskeletal disorders (WMSDs). To overcome this problem, identification of the risk factors and preventive measures for MS pain are of paramount importance to dentists in order to improve their quality of life and work. OBJECTIVES: The aims of this study were to recognize the risk factors for MS pain and their impact on dental work, as well as to identify preventive measures of MS pain among dentists. METHODS: Self-reporting questionnaire consisting of 78 questions was exclusively developed …for the study and sent to 500 working active dentists in Serbia. RESULTS: Response rate was 71.2% (356 dentists). The prevalence of MS pain was 82.6% among dentists. The main risk factors for MS pain were advanced age, female dentists, presence of chronic diseases, long working hours, and high frequency of treated patients. The most effective preventive measures in preventing MS pain were massage treatments and physical activities. Followed by use of ergonomically designed equipment, correct and dynamic working positions, and an adequate workflow organization. CONCLUSION: The risk factors for MS pain and their impact on dental work should widely be disseminated among dentists. Importantly, proper implementation in everyday life of adequate preventive measures is essential for preventing MS pain and development of WMSDs. Show more

Abstract: BACKGROUND: Stroke has been identified as a global cause of neurological disability with a resultant burden shared not only by the survivor but also by society. The resumption of an individual’s role as a worker after having a stroke, is an important rehabilitation goal. South-West Nigeria has experienced a high incidence and prevalence of stroke, leaving a quarter of survivors with severe disabilities and difficulties in community integration after rehabilitation. OBJECTIVE: The study was aimed at exploring and describing the experiences of rehabilitated stroke survivors and perceptions of stakeholders about stroke survivors returning to work in South-West Nigeria. …METHODS: A qualitative research design was used to explore these experiences and perceptions from 19 participants, comprising nine stroke survivors, two key informants, who were rehabilitation specialists, and eight caregivers of the respective stroke survivors. The researcher made use of focus groups with the caregivers and semi-structured interviews with the stroke survivors and rehabilitation specialists. The data from the study were analysed using thematic analysis. RESULTS: Three themes emerged: Themes one and two described the barriers experienced by the stroke survivors on returning to work. Theme three described the factors that facilitated the resumption of the worker role. CONCLUSIONS: The study findings clearly depicted the many barriers experienced by stroke survivors and how these negatively impact their worker roles. Limited facilitatory factors exist to assist stroke survivors in regard to adapting to their worker roles. Promoting participation of stroke survivors in work emanating from government policies was deemed to be a necessary recommendation for the study. These policies were seen to be achievable if rehabilitation resources were improved. Show more

Abstract: BACKGROUND: In an advanced nuclear power plant (NPP), the operators are responsible for monitoring a massive number of alarm parameters. OBJECTIVE: To assist the operators, a monitoring-aid system (MAS), that applies four quality control chart methods, was proposed and evaluated. METHODS: Two types of MAS, namely, text and graph marks, were proposed and compared with the original display. To validate the proposed MAS, 17 professional engineers and operators were invited to join an experiment. Two different system states, normal and abnormal, were simulated. The operators were asked to manipulate the system, monitor the critical parameters, search …for operational procedures, and deal with other secondary tasks. The primary and secondary task performance and heart rate were measured. After each task was conducted, three subjective rating questionnaires, namely, mental workload, situation awareness, and preference ratings, were implemented for the proposed MAS and the original system. RESULTS: With the assistance of the MAS, the alarm detection rate, secondary task performance, and subjective mental workload demonstrate significant improvements. The proposed MAS helps the operators monitor critical parameters. CONCLUSIONS: Therefore, the MAS should be considered for implementation with the control panel to increase the safety of NPPs. Furthermore, the MAS could reduce the mental workload might decrease the health hazard of the operators. Show more

Abstract: BACKGROUND: The aim of the study was to determine the parameters of the postural changes between two sitting positions: sitting on a saddle chair compared to sitting on an office chair. OBJECTIVE: The aim of the study was to determine the impact of an adjustable saddle chair compared to an adjustable office chair with a backrest on sitting posture. METHODS: The study involved 60 healthy subjects, mean age 24.7±2.3 years. The study used a MORA 4G system, operating on the basis of spatial photogrammetry. RESULTS: It was found that there were statistically significant differences …regarding the depth of thoracic kyphosis and the angle of the trunk forward inclination. These values were lower when measured on a saddle chair, and the inclination of the upper thoracic section and the lumbar lordosis depth were significantly higher when sitting on a saddle chair. CONCLUSIONS: Sitting on the saddle chair caused the positive effect of an increase of lumbar lordosis. A significant increase in the protraction in the cervical spine was observed, which would be considered to be a negative effect. Show more
