Abstract: BACKGROUND: Workplace Ergonomics and Human Factors (E/HF) remains as relevant and important as ever to respond to contemporary workplace design challenges. Therefore, E/HF expertise must be involved in early and appropriate phases of the workplace design process, in order to leverage user needs and requirements to constrain the proposed design solution. In this process, design decisions are made. OBJECTIVE: The aim of this article is to describe the use of a systems-theoretical framework as a guide in collaborative workplace design, focussing on planning and documenting which decisions and activities should involve E/HF expertise. METHODS: As this …is a conceptual paper, its method is to synthesise a framework from a combination of design process methodology-, general systems theory- and sociotechnical systems literature. RESULTS: The framework organises the design decisions to be made into hierarchical abstraction levels and cross-cuts them into five perspectives from which the design problem can be viewed holistically. CONCLUSIONS: The ACD3 framework is intended as an enabler of many types of design, including the design of work systems. It provides a framework that allows all stakeholders to converge around design decisions that ensure that the work system is optimised to human characteristics and the activity to be performed.

Abstract: BACKGROUND: Lumbar disc-related disorders are a main cause of work-related osteo-articular morbidity. Lumbar disc surgery (LDS) has been chosen as sentinel event for the epidemiological surveillance of these disorders since LDS can be identified in the medical databases from public and private hospitals. OBJECTIVE: To assess the theoretical impact of workplace-based primary interventions designed to reduce exposure to personal and/or work-related risk factors for LDS. METHODS: Cases of LDS were assessed using hospital discharge records for persons aged 20–64 in 2007-8 in the French Pays de la Loire region. We estimated the number of work-related cases …of LDS (WR-LDS) in high-risk industry sectors. Three theoretical scenarios of workplace-based primary prevention have been simulated: a mono-component work-centered intervention reducing the incidence of WR-LDS by 10%, and two multicomponent global interventions reducing the incidence of all cases of LDS by 5% and 10% by targeting personal and occupational risk factors. RESULTS: Four high-risk sectors were identified, amounting to 277 [216–352] cases, of which 98 [37–175] were WR-LDS: construction and information & communication for men; wholesale & retail trade and accommodation & food service activities for women. AFE was limited for each industry sector, 30%, 50%, 33% and 55%, respectively. CONCLUSIONS: Prevention scenarios combining actions on personal and occupational risk factors would be the most effective, compared to prevention focused only on occupational risk factors. Implementing actions of promotion of health at work would be necessary in addition of actions on occupational risks. Show more

Abstract: BACKGROUND: Measurement of hand exertion is very important to quantify the risk of Work-related Musculoskeletal Disorders (WMSDs) in manufacturing fields. Although a direct measurement is the most accurate way to quantify physical load, it is expensive and time consuming. To solve this limitation, a subjective self-report method has been proposed as a possible alternative. OBJECTIVE: The purpose of this study was to analyze the accuracy of subjective perception for grip force exertions associated with handedness (dominant and non-dominant hands). METHODS: A total of nine healthy adults participated in this study. All participants were …asked to exert hand grip forces for randomly selected target force levels without any information about the actual target force levels. Then, participants were also asked to rate the subjective perception of their exertion level using % Maximum Voluntary Contraction (MVC) after each hand grip force exertion. RESULTS: The trend of subjective perception for various target force levels was different according to the handedness. In the case of the dominant hand, participants tend to rate less MVC levels (under-estimation) than the actual target force levels at lower than 50% MVC, whereas they tend to rate more MVC levels (over-estimation) than the actual target force levels at higher than 50% MVC, respectively. In case of non-dominant hand, generally participants showed over-estimate for all levels of MVCs in this study. CONCLUSIONS: According to the results of this study, subjective perception of exertion showed different patterns on the handedness (S-shape for dominant hand vs . over-estimation for non-dominant hand) for various target force levels. Therefore, it would be necessary to apply different criteria for each hand to evaluate subjective perception of hand grip exertion tasks. Show more

Abstract: BACKGROUND: Flexed head and neck postures are associated with the development of neck pain in the office environment. There is little evidence regarding whether a wearable posture sensor would improve the head and neck postures of office workers. OBJECTIVE: The aim of this study was to evaluate the effect of the wearable posture sensor on the posture and physical demands on the head and neck during office work. METHODS: Nineteen participants performed a typing task with and without the wearable sensor in the sitting and standing positions. They were allowed to adjust their workstation during the experiment based …on a psychophysical method. The flexion angles of the head and neck, the gravitational moment on the neck, and the positions of the workstation components were measured. RESULTS: On average, participants with the wearable sensor had 8% lower neck flexion angles and 14% lower gravitational moments on the neck than those of participants without the wearable sensor. The effect of the wearable sensor on reducing postural stress of the neck was more significant when using the standing workstation compared to the sitting workstation. CONCLUSIONS: The wearable posture sensor could be an effective tool to alleviate the postural stress of the neck in the office setting. Show more

Abstract: BACKGROUND: Outdoor workers experience high injury rates in the winter due to slipping on ice and snow. Our testing program has demonstrated that most safety footwear does not provide adequate slip-resistance and/or comfort in icy conditions. OBJECTIVE: Our objective was to determine which of the most commonly worn safety footwear available to outdoor municipal workers in Toronto, Ontario, Canada would best prevent slips on icy surfaces and which models had good wearability. METHODS: We selected 45 of the most popular types of winter footwear worn by these workers and applied our Maximum Achievable Angle (MAA) test …method to rate the slip-resistance of the footwear. A ten-point rating scale was used for recording participants’ perceptions of wearability. The MAA test measured the steepest ice-covered incline that participants can walk up and down without experiencing a slip. RESULTS: Of the 45 types of footwear tested, only one model achieved an MAA score of 8 degrees that exceeded our cut-off for acceptable performance set at 7 degrees. Secondary measures of performance including thermal insulation; wearability and heaviness of footwear tested were also ranked. CONCLUSION: Our results demonstrate that footwear manufactures have the opportunity to differentiate their footwear by investing in slip-resistant outsole materials. Show more

Abstract: BACKGROUND: Despite income growth and improvement in Chinese soldiers’ social status, indicators related to occupational well-being have not improved significantly, such as job satisfaction and occupational commitment. OBJECTIVE: This study aimed to examine the mediating effect of occupational commitment on the relationship between relative deprivation and job satisfaction in Chinese Army officers. Additionally, the moderating effect of career calling was also explored. METHODS: 245 army officers (184 male, 61 female) in a short-term training class were recruited as participants and completed questionnaires that measured relative deprivation, occupational commitment, career calling, and job satisfaction. Multivariate regression analysis, …bootstrap test, Sobel test, and path analysis were adopted to test the moderated mediating effect. RESULTS: Multivariate regression analysis showed that occupational commitment partially mediated the relationship between relative deprivation and job satisfaction. The results of the bootstrap estimation procedure and subsequent analyses indicated that the indirect effect of relative deprivation on job satisfaction was significant. Additionally, career calling significantly alleviated the effects of relative deprivation on occupational commitment and job satisfaction. Path analysis showed the moderated mediating model fit the data well. CONCLUSIONS: Occupational commitment partially mediates the effect of relative deprivation on job satisfaction, and career calling can moderate the effects of relative deprivation on occupational commitment and job satisfaction in Army officers.

Abstract: BACKGROUND: Working in direct contact with the public may involve psycho-social hazards for employees who are frequently exposed to rude or verbally aggressive customers. Negative encounters may undermine employees’ well-being and job performance, impairing the quality of the service provided with tangible costs for organizations. OBJECTIVE: The paper provides a systematic review of research on customer incivility and verbal aggression in service settings using the following framework 1) antecedents of customer misbehavior as reflected in worker perceptions, customer reasons and environmental factors; 2) maladaptive and adaptive coping strategies used by service providers in response to customer incivility and …verbal aggression; 3) effects of customer incivility and verbal aggression on service providers’ well-being and work-related outcomes; and 4) practical implications for the management. We present a model of the relationships between these four areas. METHODS: A systematic review was conducted using PsychINFO and Scopus. RESULTS: Fifty-three papers (20 pertaining to customer incivility and 33 pertaining to customer verbal aggression) were included. CONCLUSION: Both customer incivility and verbal aggression may impair employees’ well-being and job outcomes. Current gaps, practical implications, and directions for future research are discussed.

Abstract: BACKGROUND: Job stress can positively influence individuals’ work motivation; however, it is more typical for job stress to have adverse physical and psychological effects, which in turn undermine job satisfaction. OBJECTIVE: The present study has two purposes: to evaluate the effect of the health-promotion lifestyle and job stress to job satisfaction and turnover intention, respectively; and to investigate the moderating effect of mindfulness on each relationship. METHODS: The present study surveyed 200 nurses employed at small-to-medium-sized hospitals in South Korea. To verify the internal consistency, the reliability of the scales that was administered with the Cronbach’s …alpha. Correlations between mindfulness, health-promotion lifestyle, job satisfaction, stress factors, and turnover intention were analyzed. The moderating effect of mindfulness on the relationships among aforementioned measures were evaluated. RESULTS: We found significant associations between the health-promotion lifestyle and job satisfaction (p  < 0.001), and mindfulness had a moderating effect on the relationship between the health-promotion lifestyle and job satisfaction (p  < 0.05). CONCLUSIONS: The enhancing effect of mindfulness in these relationships can suggest an important role of mindfulness in the relationship between life style and job attitude. Show more
