In particular, in emission control of mobile and stationary sources. CO pollutant, which is emitted from various emission sources is a toxic gas and employee exposure at indoor and outdoor workplaces is one of the main world challenges. The approach of present study is to investigate the key performance parameters of non- thermal plasma in CO treatment efficiency by considering of techno- economic considerations at reactor design. Methods: A coaxial reactor composed of two inner (quartz) and outer (pyrex) tubes as dielectric material, tungsten electrode as cathode and copper foil as anode material has been used. In this study, we have investigated the parameters of temperature, space time, reductant gas, and current intensity of power supply voltage on removal efficiency of the pollutant. Sample size and sampling methods are determined based on the experimental design (i,e,. in two and four level) and  ASTM D5835 standard method, Respectively. Data analysis has been done by SPSS software (version 22). Results: The mean conversion of 28- 29% for carbon monoxide is achieved under optimum conditions by temperature of 110 oC, propane to carbon monoxide ratio of 0.05 and SIE of 1000- 1400 j/l. This is one of the main results of present research and suitable primary alternatives at future researches to utilize non- thermal plasma technology. Conclusion: In this study, the key parameters of space time and temperature have been shown significant effect on removal efficiency of pollutant. While, due to molecular- chemical structure of CO gas and complexity of participation during redox reactions in NTP reactor, the presence and concentration of propane gas has no significance effect on treatment efficiency. So, consideration of relevant parameters of electron density, gas mixture properties, and geometric characteristics in designing step could play key role in optimization of temperature conditions and pollutant space time.  }, Keywords = {Air pollution, carbon monoxide, non- thermal plasma, removal, emission}, volume = {15}, Number = {4}, pages = {50-61}, publisher = { Iran University of Medical Sciences}, url = {http://ioh.iums.ac.ir/article-1-2161-en.html}, eprint = {http://ioh.iums.ac.ir/article-1-2161-en.pdf}, journal = {Iran Occupational Health}, issn = {1735-5133}, eissn = {2228-7493}, year = {2018} } @article{ author = {Zendedel, Rezvan and Panjali, Zahra and EsmaeeliTahneh, akbar}, title = {Normal hexane occupational exposure estimation in the benchmark response according to color vision impairment}, abstract ={Background and aims: Exposure to the normal hexane can induce dysfunction of the nervous system and color vision impairment. Occupational risk assessment is established according to no observed adverse effect levels (NOAEL). Recently, because of the NOAEL’s limitations, the benchmark responses were applied for risk assessment. The study’s aim is an analysis of benchmark response in occupational exposure to the normal hexane by color vision impairment. Methods: In this study, inhalation exposure to the normal hexane of some shoemakers was evaluated based on the OSHA ID-07 method. Two samples performed for each subject and cumulative exposure was estimated. Acquired color vision impairment was assessed by a D-15 technique in the both exposed and control groups. A dose-response curve was plotted by normal hexane cumulative exposure and color vision impairment according to the BMDS EPA software. Results: Exposure to the normal hexane in all studied workers was lower than OELs. It was found that 33% of the exposed groups had acquired color vision impairment. A dose-response curve was evaluated by five exposure groups in the range concentration of 0, 10.82, 11.97, 15.11 and 18.55 mg/m3.The results show Log Logistic model is the best model for the benchmark response prediction. Occupational exposure in 10% of responses (benchmark response) was determined 19.54 mg m-3 with a lower limit of 12.15 mg m-3. Conclusion: Neurological toxicity occurred in the levels of airborne exposure lower than occupational exposure limit.

So it is necessary that we have identified the factors that have role in the creation of such behaviors. Therefore, this study seeks to relationship Workaholism with aggressive behaviors with mediate role of job emotions in the workplace. Methods: this research on the basis of objective is practical and the method of collecting data is descriptive-correlation. The Statistical Society consists of all nurses in hospitals of Golestan, Imam Khomeini, Abuzar and Razi in the city of Ahvaz, which sample size was selected 310 with stratified random sampling. In this research to measure variables of obsessive workaholism and success-oriented Workaholism was used of questionnaire of  aziz and et al and to measure variables of job emotions and aggressive behaviors in the workplace was used Respectively of  questionnaires of Watson & Telegen and Hershcovis and et al. Results: the results show that there is a significant positive relationship between the obsessive Workaholism and aggressive behaviors, while the significant negative relationship of success-oriented Workaholism with aggressive behaviors is not confirmed. Also the results confirms the mediate role of positive and negative emotions in the relationship between Workaholism and aggressive behaviors, and positive emotions have full mediating role in the relationship between success-oriented Workaholism and aggressive behaviors, and negative emotions have incomplete mediate role in the relationship between  obsessive Workaholism and aggressive behaviors. Conclusion: the results of the research shows that with increasing the intensity of Workaholism among nurses, the intensity of aggressive behaviors will be increasing among them. Since one of the factors in creating aggressive behaviors is lot of works and work in stressful environments, so it is suggested that managers avoid from giving lot of works to their personnel and in order to reduce Workaholism, they should be developed an organizational culture that is based on proper performance and replace it instead of the organizational culture that encourages employees to hard working.}, Keywords = {Workaholism, job emotion, aggressive behaviors, nurses}, volume = {15}, Number = {4}, pages = {73-83}, publisher = { Iran University of Medical Sciences}, url = {http://ioh.iums.ac.ir/article-1-1972-en.html}, eprint = {http://ioh.iums.ac.ir/article-1-1972-en.pdf}, journal = {Iran Occupational Health}, issn = {1735-5133}, eissn = {2228-7493}, year = {2018} } @article{ author = {Jafari, Asghar and MashhadiAbbasi, Ansiyeh}, title = {The Prediction of Job Motivation of medical employers of Red Cross Organization based on Defense Mechanisms and Culture Intelligence}, abstract ={Background and aims: In occupational counselling have been emphasised on effect of personality, cognitive and affective traits in genesis, development and level of motivation.
