Abstract
Introduction: Human error is considered as a crucial challenge in occupational settings. Health care system is amongst occupational environments with high rate of human errors. Numerous preceding studies noted that more than 2/3 of medical errors are preventable. Accordingly, different methods are suggested to evaluate human errors, especially in nuclear industries. The aim of this study was to evaluate the application and accuracy of HEART technique in medical health system.
Material and Method: This qualitative study was conducted in surgical intensive care units of a hospital in Shiraz city. All nurses recorded errors were categorized regarding the given tasks and then all tasks were ranked based on the number of errors. The probability of nurses’ tasks error was estimated through AHP-HEART method and the resultant ranking was compared with the recorded errors. Additionally, the prioritization of contributing factors to errors, determined by AHP and AHP-HEART methods, was compared employing Pearson statistical test.
Results: Based on the results, there was a concordance in the rate of nurses’ error determined by HEART method and the recorded errors. However, no significant correlation was between errors contributing factors determined by AHP and AHP-HEART methods.
Conclusion: This study suggested that although HEART technique was successful to rank the tasks considering the magnitude of error probability, but the coefficients of error producing conditions should be customized for nurses’ tasks in order to provide appropriate control measures.

Abstract
Introduction: Carpal tunnel syndrome is followed by pushing Median nerve in the carpal tunnel of the wrist. Occupational factors such as repetitive movements of the hands and fingers and frequent wrist disturbances affect the development of this syndrome. Quality of life is a multidimensional concept including physical and mental performance. The aim of this study was to determine the prevalence of CTS and its impact on the quality of life of typists in Tehran.
Material and Methods: This analytic descriptive cross sectional study was conducted in 1396 on 363 typists from 50 typing institutes in Tehran. Data were collected Demographic-Job Profile Questionnaire, Boston (BQ), quality of life (SF36) and Visual Analog Scale (VAS). Data were analyzed using SPSS-22 software and methods such as ANOVA and Pearson correlation tests.
Results: Among 363 participants, 215 of them were female (59.23%) and 148 were male (40.77%). The mean age was 37 ± 12.58 years. Among the typists, 51 (14.55%) had one-sided hand conflict, and 312 (85.95%) were two-sided hand conflicts. Results indicated that the prevalence of CTS symptoms among women was higher than that of men The value of Pearson correlation coefficient (range: 0.0613-0.783) showed that there was a moderate to strong correlation between the severity of symptoms scale (SSS), functional status scale (FSS) and visual analog scale (VAS) in the population under study (p< 0.05). There was also a strong and significant correlation between SSS and FSS among typists. In this study, CTS symptoms have a significant negative effect on the quality of life of the typists, but the psychological dimension quality of life is not to be affected by these symptoms.
Conclusion: Regarding the existence of CTS symptoms among typists who work most of a day with computers, there is also a statistically significant relationship between the incidence of CTS symptoms and the quality of life in this occupational group. Therefore, it is recommended that more attention should be paid to these individuals, appreciate tools be correctly designed, and further study be done.

Abstract
Introduction: Nowadays, air pollution is now considered to be the largest environmental health threat. This study was conducted with the aim of determining occupational exposure to chemical pollutants, including sulfur dioxide (SO2) and hydrogen sulfide (H2S) and assessing the health risk of exposure to these compounds using a combination of AERMOD and SQRA methods.
Material and Methods: The present study is considered as a descriptive-analytical and cross-sectional research, which was conducted in 2002 in one of the gas air refineries of South Pars in the Persian Gulf region, in such a way that the amount of emissions coming out of refinery chimneys was measured by the Testo 350- XL. AERMOD model was used to simulate the dispersion of H2S and SO2 chemical pollutants. Respiratory exposure and health risk assessment of refinery personnel and nearby residents were performed using the recommended method by the Singapore Occupational Health Services Pte Ltd.
Results: Hydrogen sulfide and sulfur dioxide were introduced as the most dangerous chemicals. According to the results, the highest risk value for sulfur dioxide among the exposure groups was related to the sulfur recovery unit (SRU), the west side of the Train Gas unit and the gate pass building of the refinery, and the highest risk values for sulfur dioxide among the exposure groups were related to the HSE building, security door, fire stations building, tanks, steam generating unit, west side of Train Gas unit, dining hall and gate pass building of the refinery. Hydrogen sulfide obtained a low to medium risk level, and sulfur dioxide a low to high risk level in terms of frequency.
Conclusion: This model can be considered as a suitable and quick solution in the superior management of the concentration of pollutants and also a promising solution in order to increase the ability of decision makers to assess the health risk of industries’ personnel. Also, ensuring quality monitoring results and reducing sampling costs are discussed.
