Background & objectives: The challenges in government organizations and centers, including medical universities in the country, indicate the existence of several organizational problems, and without a doubt, the existence of these problems will reduce the effectiveness, efficiency and productivity of the organization. A significant part of these problems is related to the staff recruitment process. Improper selection of these staffs will impose irreparable damage on organizations and consequently on public health. Therefore, the purpose of this study was to investigate the process of manpower selection in Iran and other countries, since the process of human resources recruitment in Iran and the world is different. Methods: Methods: The present study is a descriptive study. The statistical population includes all universities in the world that work in the field of medical services delivery. Information about the process of selecting and employing human resources was collected by searching valid Persian and English sources using the keywords Human Resources Selection, Human Resources Management, Selection Patterns. Also, reference books on manpower management from different parts of the world were collected and reviewed separately. Results: The review of the human resources selection in Iran and different parts of the world indicates that there are a number of criteria due to the many cultural, social and economic differences between countries in accordance with the prevailing conditions in those countries. However, criteria such as expertise, proficiency, work experience, personal interest and the spirit of participation are common in all these countries and should be considered in the selection of human resources. Conclusion: According to the studies conducted in each country, the patterns of manpower selection should be done within a logical framework according to the prevailing conditions of

Background & objectives: Sometimes artificial dyes are used instead of saffron as a fraud to improve the color of grilled chicken. Due to the adverse effects of some industrial colors such as tartrazine on human health, this study was conducted to determine the prevalence of using this color instead of saffron in the preparation of grilled chicken. Methods: In a cross-sectional analytical study, 550 samples of colored grilled chicken were collected in a simple random sampling method in the cities of Ardabil province, 2016. Thin layer chromatography was used to extract the dye in the collected samples and the results were compared with the National Standard of Iran No. 2634. Data were analyzed by descriptive statistical tests. Results: The results showed that of the total samples of grilled chicken prepared for consumption in Ardabil province, about one third (31.81%) of tartrazine dye was used. Although, there was not significant correlation between the colors used in the samples and the sampling site using the Spearman Correlation Coefficients the percentage of using this color was different among different cities of the Ardabil province. The highest percentage of color was found in Sarein city (35.29%) and the lowest was in Kosar city (21.95%). Conclusion: The present study showed that in all cities of Ardabil province, synthetic tartrazine is used to dye grilled chicken instead of saffron dye. Almost one third of the grilled chicken samples were contaminated with tartrazine synthetic dye.

Background and objectives: First pregnancy, due to unknown pregnancy experiences, can cause psychological and emotional distress for mothers. Therefore, the purpose of this study was to investigate the effect of maternal-fetal attachment training to tolerate distress and rumination of first pregnant mothers. Methods: The research method was quasi-experimental with pretest, posttest, control group, and forty-five-day follow-up period design. The statistical population consisted of all the first pregnant mothers in Tehran in 2016. The study sample consisted of 30 first pregnant mothers with an age range between 25 and 35 years. Participants were selected through a non-random sampling method and they were randomly assigned into intervention and control groups. The intervention group received nine sessions of ninety-minute comprehensive training of maternal-fetal attachment during one month while the control group did not receive such intervention during the study process. The questionnaires used in this study included Distress Tolerance Questionnaire (Simmons and Gaher, 2005) and Ruminant Questionnaire (Nolenhoxma and Murrow, 1991). The data were analyzed by repeated measurement ANOVA. Results: The results of data analysis showed that training maternal-fetal attachment has significantly influenced distress tolerance (f=153.08, p<0.001) and rumination (f=256.11, p<0.001) in the first pregnant mothers. Conclusion: Based on the findings of the present study, it can be concluded that training maternal-fetal attachment by using relaxation and breathing techniques to reduce anxiety and mental imaging training can increase distress tolerance and reduce rumination of first pregnant mothers. Accordingly, training maternal-fetal attachment can be applied as an effective treatment to reduce the distress tolerance and rumination of first pregnant mothers.

Background & objectives: One of the most important water-related issues is the pollution of water resources, which is mainly due to human activities and currently threatens many water resources in the world. Therefore, the use of appropriate tools to manage surface water quality seems necessary. This study was conducted to determine the potential risks of pollutants in Sabalan Dam using a WRASTIC model. Methods: WRASTIC evaluation model and GIS software were used to assess the risk of Sabalan Dam pollution accidents. To determine the level of pollution risk, the catchment area of Sabalan Dam was divided into 8 sub-basins. Then, in each sub-area, pollution source maps including various indicators of industrial effluents, agriculture, housing, recreation and transportation accidents were prepared in GIS software environment. Then scoring for each indicator was performed based on the potential intensity of pollutant sources. Finally, based on the obtained data, sub-basins were classified in terms of risk. Results: The results showed that based on the model used in terms of health and environmental pollution risk, the average risk of water pollution for the catchment area of Sabalan Dam was 48.29. Classification of the level of pollution risk in the sub-basins of Sabalan Dam showed that sub-basin S1 had a high level of risk and the level of risks in subbasins S2 and S4 were moderate. Conclusion: The use of WRASTIC model in determining the risk level of Sabalan Dam pollution accidents showed that the most important indicators of Sabalan Dam catchment was the entry of domestic wastewater and effluents of aquaculture and agricultural activities and mineral hot springs. The results of this study indicated the desirability of using the WRASTIC model in determining the pollution risk of the Sabalan dam catchment.

Background& objectives: Zarrinehrud River is one of the most important permanent and water-rich rivers in West Azerbaijan province located in the catchment area of Lake Urmia. In this study, to evaluate the quality of the Zarrinehrud River, with a length of 57.5 kilometers from the outlet of Noroozlou to the drainage dam to the Lake Urmia, QUAL2K computer simulation model was used. Methods: The selected parameters of the model included: flow, dissolved oxygen (DO) and biochemically required oxygen. The selected time for the simulation was May 2016. Model calibration was performed by determining the oxidation coefficients of carbonaceous materials and the re-aeration coefficient of the river, using the mean square root of error (RMSE) method Results: The results show that the water quality of the river downstream of the Noruzlu regulatory dam has caused significant changes in the quality parameters of the river due to receiving wastewater from slaughterhouses, sugar factories, urban, rural and agricultural drains. Conclusion: Due to the high self-purification capacity of the river, the amount of dissolved oxygen is appropriate and the amount of BOD has reached an acceptable level despite a sudden increase. In terms of matching the observational data with the output diagram of the model, there was a good fit in other parameters except flow rate. In the case of noncompliance of the observed flow data with the simulation diagram, it may be due to unauthorized withdrawals from the river for agricultural purposes.
