Cognitive failure is one of the factors which can be influenced by personal and professional characteristics. Hence, this research was carried out to study the effect of workrelated quality of life (WRQoL) and some related factors on cognitive failures (CF) among nurses. Methods. This cross-sectional study was conducted among nurses working in ICU (Intensive Care Unit), CCU (Critical Care Unit), and Emergency Units, in 2014. Results. In this study, 750 nurses participated. The mean ± SD of the total CFs and WRQoL were obtained as 40.5 ± 12.7 and 75.8 ± 13.7 respectively. The result shows that CF statistically has a significant difference among the age groups, experience groups and working units. Multiple regression tests show that age, income and WRQoL have a significant effect on CF. Based on the results, for a unit increase in WRQoL, we expect a 0.26 unit decrease in CF. Analysis of variance (ANOVA) results show that emergency ward had changed the overall effect of WRQoL on the CF, after the effect of WRQoL was controlled. Conclusions. Overall results of the present research indicated that despite the high level of WRQoL among understudied nurses, the rate of CF was not in an appropriate level. Development of supportive and interventional strategies is highly recommended.

Drivers are a high-risk group for work-related stress. The purpose of this study was to determine the association between cardiovascular risk factors and occupational stress among locomotive operators. Methods: This cross-sectional study recruited 350 locomotive operators. The Osipow questionnaire was used to measure stress. After 10 hours of fasting, systolic and diastolic blood pressures were recorded. Intravenous blood samples were also taken. Two groups of job stress were included as "trivial and trivial-to-average stress" and "average-to-acute and acute stress". The Mann-Whitney U test was utilized to compare the risk factors of cardiovascular disease between the 2 groups. The association between education level and job experience was assessed using the χ 2 test. Results: Of the 350 participants, 250 (71.43%) individuals reported average-to-acute stress, 30 (8.57%) reported acute stress, and 70 (20%) reported average stress. There was a significant relationship between education level and job experience (P=0.000). There were no significant differences between the 2 groups in the smoking rate (P=0.92), triglyceride level (P=0.55), and diastolic blood pressure (P=0.21), while the trivial and trivial-to-average stress group had significantly higher blood glucose levels (P=0.024) and systolic blood pressures (P=0.000) than the other group. Finally, the blood cholesterol level in the average-to-acute and acute stress group was significantly higher than that of the other group (P=0.000). Conclusions: High rates of occupational stress were reported in the studied locomotive operators. Stress may have effects on blood glucose, triglyceride, and cholesterol levels in this job group.

Objectives: The aim of the study was to assess the organizational structure of the selected manufacturing industries located at the Qom Province, and its relations to occupational health and safety concerns and success in 2015. Materials and Method: This cross-sectional study was conducted among 39 randomly chosen manufacturing companies. The data collection was conducted using valid Robbins's organizational structure questionnaire. Higher scores indicate higher levels of the respective components. Questionnaires were completed by middle managers of selected companies. Data were analyzed by Pearson correlation using SPSS version 20. Results: The average number of the employed personnel in these companies and organizations' work experience was 105.1 ± 101.1 persons and 15.3 ± 12.1 years, respectively. Average scores of complexity, formalization, and centralization was 14.3, 21.3, and 31.2, respectively. Among the studied organizations, 38.6% of the organizations had formalization, 2.6% had complexity, and 56.6% had high centralization. The results of Pearson's correlation test showed that there was a relation between complexity and organizational size, as well as centralization and work experience of the company significantly (P < 0.05). Conclusion: More than half of the studied organizations had a centralized structure. It should be noted that at a low level authority status, activities related to the health, safety, and ergonomics (HSE) field cannot have the appropriate performance. In addition, it revealed that more than 60% of the studied companies had not formalization. In summary, based on the results of the present study, favorable future conditions of HSE situation is not predictable.
