Some studies have suggested a possible association of occupational exposure that may cause cardiovascular effects. Lead is absorbed through the body through the skin, skin, and respiratory tract and penetrates some tissues. Considering the importance of labor health in each country's development and progress, this study was conducted to determine the amount of lead in the blood of painters in Rafsanjan in 2019.   Materials and Methods: The present study is a cross-sectional study of the descriptive type conducted in 1397 on 77 painters of Rafsanjan city. Data collection was done in two stages, in the first stage, based on a checklist that included demographic information, and in the second stage by performing laboratory tests. Finally, by recording the data in SPSS software, quantitative data was reported as a "mean ± standard deviation" and qualitative information as a "number (percent)".   Results: Of the 77 painter workers, the youngest is 21, and the oldest is 70 years old. A total of 20 people (26%) had a family history of heart attacks. The highest amount of lead in the blood of painters was reported to be 30.7 micrograms per deciliter, and the level of lead was most correlated with blood sugar. Sixty people (77.9%) painters used personal protective equipment. 49.4% of the study's painters wore work clothes, and 28.6% used gloves while working. Lead levels are directly related to blood sugar, cholesterol, triglyceride, LDL, age, work experience, and blood sugar levels were most correlated with the level of lead in painters' blood.   Conclusion: This study's findings show that due to the increase in the work experience of painters, their blood lead level has also increased, and the blood sugar level has had the highest correlation with the lead level in the painters' blood.   1062 Safety and occupational accidents Assessment of the probability of human error occurring in the process of appendectomy operation using SPAR-H method Taherzadeh Chenani khalil n Jahangiri Mehdi o Jafari Nodoushan Reza p Madadizadeh Farzan Fallah Hossein n Department of Occupational Health Engineering, School of Public Health, Shahid Sadoughi University of Medical Sciences, Yazd, Iran o Department of Occupational Health Engineering, School of Public Health, Shiraz University of Medical Sciences, Shiraz, Iran p Department of Occupational Health Engineering, School of Public Health, Shahid Sadoughi University of Medical Sciences, Yazd, Iran Research Center of Prevention and Epidemiology of Non-Communicable Disease, Department of Biostatistics and Epidemiology, School of Public Health, Shahid Sadoughi University of Medical Sciences, Yazd, Iran Department of Occupational Health Engineering, School of Health, Tabriz University of Medical Sciences, Tabriz, Iran 1 10 2020 12 2 17 28 17 03 2020 02 08 2020 1.O'Connor PO, Keogh IJ.

The aim of the present study was to investigate the probability of human error in operating room personnel in the process of appendectomy operations. Materials and Methods: This cross-sectional and descriptive study was performed to identify and evaluate the probability of human error in operating room personnel's tasks in the process of appendectomy in Shahid Sadoughi Hospital in Yazd. Initially, by interviewing personnel and studying the process and procedures of the work, the job duties of the personnel were analyzed using HTA method. Finally, the probability of error was calculated using SPAR-H method for different tasks. Results: The average human error probability for all tasks was 0.173. Also, the highest mean of error was related to anesthesiologist duties (0.23) and the least related to scrub duties (0.101). Conclusion: The SPAR-H method can be used to analyze and quantify the probability of human error in the operating room. To reduce the likelihood of human error, we can reduce dependency by performing different tasks with different people and if possible with long time between them. Also, stress, complexity and procedures were identified as the most important factors affecting the probability of error. 1041 occupational medicine The effect intervention psychological- based on emotional regulation on reduction job stress among nurses working in hospitals kermanshah city: case study of imam reza hospital Hatamian Peyman Hatamian Parastoo Department of Psychology, Faculty of Humanities, Tarbiat Modares University, Tehran, Iran Department of Economics, Faculty of Social Sciences, Razi University, Kermanshah, Iran 1 10 2020 12 2 29 35 06 10 2019 01 10 2020 Introduction: Considering that job stress is one of the most commonly used areas related to health psychology in the workplace.

This study aimed to investigate WAI and its relationship with VO2max at one of the cement companies. Materials and Methods: This cross-sectional study was conducted among 130 employees of a cement company in Iran in 2018. For data collection, the WAI, Queens's test for maximum oxygen consumption, and a questionnaire designed by researchers (socio-demographic and work-related factors) were used. SPSS 21 was used to analyze the data.  Results: The results showed that the mean ± standard deviation of WAI in staff was 39.35 ± 4.64. Among the demographic and related variables, sports activity (P > 0.04) and sleep quality (P < 0.001), and work experience (P> 0.046) were significantly correlated with WAI. There was a significant positive correlation between the mean score of WAI and Vo2max (r = 0.21, p < 0.05). Regression modeling showed that Vo2max was the only significant predictor of WAI. Conclusion: According to the results of the study, to control and enhance the ability of the staff of the study, occupational intervention programs should focus on improving sleep quality and increased exercise. Also, considering the positive relationship of Vo2max to the WAI of the surveyed staff, it is recommended to select suitable employees in terms of aerobic capacity according to the workload of the job. 1064 occupational medicine The role of physical activity on blood factors, lipid profile, and liver enzymes of tile factory workers (A Case Study) Dashty khavidaki Mohammad Hassaan Minaeifar Amir Abbas Rasekh Fatemeh Baghiani Alireza Assistant Professor of Sports Physiology, Department of Physical Education, Payame Noor University, Tehran, Iran Assistant Professor, Department of Biology, Payame Noor University, Tehran, Iran Assistant Professor, Department of Biology, Payame Noor University, Tehran, Iran M.Sc., Department of Management, Payame Noor University, Tehran, Iran 1 10 2020 12 2 47 58 24 03 2020 01 10 2020 Introduction: Inhalation of dust particles is prone to chronic diseases, and regular exercise reduces the risk of cardiovascular disease and improves blood variables. The purpose of this study was to investigate the role of physical activity on blood factors, lipid profile, and liver enzymes in tile factory workers. Materials and Methods: This is a cross-sectional study. 70 workers who were eligible to participate in the study were selected based on the sampling method available at the workplace.
