Nous avons mene deux e tudes pour savoir si le modeÁ le en trois composantes de l'implication organisationnelle (Meyer & Allen, 1991) e tait transposable aÁ une culture non occidentale, en l'occurrence la Core e du Sud.

In Study 1, we found that when the 6-item versions of the scales (Meyer, Allen, & Smith, 1993) were translated into Korean, the psychometric properties of the Affective Commitment Scale were similar to those found in North America, but problems were identified in the Continuance and Normative Commitment Scales. In Study 2, we found that these problems could be overcome by adopting a revised set of items written in North America. The new scales demonstrated good psychometric properties in terms of factorial validity, internal consistency, and criterionrelated validity with respect to turnover intention. We concluded that the three commitment constructs are likely to generalise to non-Western cultures, but that there might be a need to refine the measures for cross-cultural research.

ObjectivesSleep is essential for human beings to live and work properly. This study was conducted to investigate the relationship between occupational exposures to workplace risk factors and sleep disturbance in Korean workers.MethodsThe data were drawn from the second Korean Working Conditions Survey (KWCS); a total of 7,112 paid workers were analyzed. The independent variables were occupational exposures such as physical, chemical, biological, and psychosocial risk factor in the workplace, and psychosocial risk factor was divided into five categories (job demand, job control, social support, job insecurity, lack of reward). We estimated the relationship between various occupational exposures and sleep disturbance using multivariate logistic regression analysis.ResultsThe results showed that people who exposed to physical, chemical, biological, and psychosocial (high job demand, inadequate social support, lack of reward) risk factors were more likely to increase the risk of sleep disturbance. Furthermore, after adjusting for general and occupational characteristics, we found significant positive associations between exposures to physical (odds ratios [OR] 1.47, 95% confidence interval [CI] 1.05-2.07) and psychosocial (high job demand (OR 2.93, 95% CI 2.16-3.98), inadequate social support (OR 1.57, 95% CI 1.14-2.15), lack of reward (OR 1.45, 95% CI 1.08-1.96)) risk factors and sleep disturbance.ConclusionThese results suggest that occupational exposures to physical and psychosocial workplace risk factors are significantly related to sleep disturbance.

This study was conducted to investigate the relationship of active and passive smoking with occupational injury among manual workers. Data from the 2011 Korean Working Conditions Survey were analyzed for 12,507 manual workers aged ≥15 yr. Overall, 60.4% of men and 5.8% of women were current smokers. The prevalence of injury was higher among never smokers who were exposed to secondhand smoke (SHS) (7.7% in men and 8.1% in women) than current smokers (4.2% in men and 4.1% in women). After controlling for potential confounders, in men, compared to those who never smoked and were not exposed to SHS, people who never smoked and were exposed to SHS (adjusted odds ratio (aOR)=3.7, 2.2–6.4) and current smokers (aOR=2.5, 1.6–3.8) were more likely to experience injury. Among women, the aORs of occupational injury were 8.4 (4.2–16.7) for never smoking women with occasional exposure to SHS and 3.5 (95% CI: 1.4–8.7) for current smokers, in comparison to never smoking women who were never exposed to SHS at work (reference group). The present study suggests that exposure to SHS is a possible risk factor of occupational injury for never smoking men and women.
