Background and Aim: Personnel of the sheriff's departments as human resources, due to the inherent characteristics of the military profession, are faced with numerous occupational problems and as a result are exposed to greater psychological vulnerability than those of other occupations. The purpose of this study was to investigate the relationship between psychological characteristics of depression, anxiety, and stress with the aggression of Tabriz city police officers and with mediating role of chronic fatigue. Methods: For this purpose, 300 clerical staff of Tabriz city were selected by cluster sampling method. To measure the variables, participants completed the measures of psychological characteristics, chronic fatigue, and aggression. Cronbach's alpha method was used to assess the reliability and validity of these scales. The results indicated the desirability of these scales. Data were analyzed using Amos software and bootstrapping test. Results: The results showed that the total effect of psychological traits on chronic fatigue (P≤, 0. 01, β,= 0. 85) chronic fatigue on aggression (P≤, 0. 01, β,= 0. 45) The psychological effect of aggression on (P≤, 0. 01, B = 0. 37) was statistically significant. The indirect effect of chronic fatigue and psychological traits with aggression was also significant (P≤, 0. 01, B = 0. 70). Conclusion: Recognition and identification of psychological traits in relation to traumatic factors of chronic fatigue of the sheriff's staff point to increased aggression and decreased ability of the person to successfully deal with important changes. Therefore, it is recommended to develop a comprehensive care plan for employees with chronic fatigue and psychological characteristics to reduce the level of aggression toward the sheriff's staff.

Background and Aim: Recognizing the factors involved in the resilience of soldiers and how to regulate emotions in the face of issues and problems of military service, can prevent the occurrence of many adverse behaviors in the military environment and also make the person more compatible with the environment. This study examines the relationship between emotion regulation and resilience and the factors affecting it in the soldiers of Marvdasht police command in 2020. Methods: The present study is a quasi-experimental pre-test-post-test with two control and experimental groups, which was performed by random cluster sampling with a sample size of 118 people (59 people in each group) in 2020 in Marvdasht police stations. Demographic with 8 questions, resilience with 25 questions, cognitive emotion regulation with 18 questions, and self-efficacy with 32 questions questionnaires were used to collect data. Information using SPSS software version 22 Chi-square, Pearson correlation, independent t-test, and linear regression were analyzed. Results: The results showed that the scores of self-efficacy and resilience before and after the intervention of emotion regulation skills on resilience were statistically significant in the experimental group (P>0. 001), while these changes were not significant in the control group (P = 0. 706). Within the groups, the scores of emotional regulations before and after the intervention in the control and intervention groups did not show a significant difference, but the mean of changes in the intervention group was higher. Also, the results of the Pearson correlation test showed that there is a correlation between resilience and emotion regulation (r = 0. 302, P = 0. 002). Linear regression analysis to determine the effect of emotion regulation on resilience in both experimental and control groups after the intervention also showed that 8% of changes in resilience score depend on emotion regulation. Conclusion: Emotion regulation skills training intervention has a significant effect on resilience using selfefficacy theory on soldiers.

Background and Aim: Corona antibody testing is one of the common methods used for diagnosing coronavirus infection due to its low cost, easy access, short testing time, and convenient sampling. Iran, with its valuable Jihadi and military resources, has been able to take some effective steps in controlling the crisis caused by this disease. This is especially important in disadvantaged and underprivileged areas. The present study aimed at investigating the prevalence of Covid-19 among people living around Hamun Lake, Sistan and Baluchestan, Iran, using serological tests while considering the access to medical and healthcare facilities. Methods: This cross-sectional study was conducted by collecting data through administering a face-to-face checklist among people living in Hamun Lake, Sistan and Baluchestan, Iran in March 2021. The checklist included the demographic data, symptoms, and underlying diseases. Laboratory and serological test data including PCR, IgM, and IgG tests were also evaluated. This study was carried out with the help of Jihadi and military forces. Results: According to the IgM and IgG diagnostic tests performed in this study, out of 622 patients, 74 were IgM positive and 105 were IgG positive. Besides, 10 participants were positive for all antigens. People over the age of 30 were significantly more likely to be diagnosed with the disease. However, there was no significant difference between men and women although women were more diagnosed with COVID-19. The most common symptoms associated with the disease in this study were cough (12%), shortness of breath (8%), and body pain (6%). Blood pressure (13%), heart diseases (9%), and diabetes (8%) were the predominant underlying diseases in the participants. Conclusion: The findings of this study indicated that the prevalence of coronavirus disease in Hamun Lake, one of the deprived areas of the country in terms of access to healthcare facilities, was not significantly different compared to other parts of the country. It can be concluded that the level of access to healthcare facilities, cannot be one of the factors affecting the prevalence and incidence of coronavirus disease, at least in this study. The present study revealed the successful experience of using military forces to help the underprivileged people of the country to manage the pandemic outbreak of coronavirus disease.

Background and Aim: Myocardial infarction (MI) is one of the leading causes of mortality worldwide. This disease imposes a high socio-economic burden on patients. Since the Spatio-temporal analysis of diseases plays an essential role in the design of prevention and management programs. The present study aimed to identify regional clusters of MI and also analyze the time trend of the disease among an Iranian military community. Methods: In this ecological study, all registered cases of MI from different provincial centers of the military community were studied during the period 2015 to 2018. The Getis-Ord Gi statistics were used to identify the hot spots of MI and the Spearman correlation coefficient to the trend of the disease. Results: The incident cases of MI in military officers and conscripts during the study period were 103 and 4, respectively. Gilan and Golestan provinces (90% confidence level) in 2015, Gilan, Golestan, Semnan, and Zanjan provinces (95% CI) and Isfahan province (90% CI) in 2016, Golestan province (95% CI), and Gilan province (90% CI) in 1396 and Golestan province (95% CI) in 1397 were identified as hot spots of the disease. The results of the temporal analysis also indicated a significant increasing trend of MI in military officers. Conclusion: The Northern regions of Iran are at high risk of MI, and the trend of the disease also demonstrates a significant increase. The findings of this study can be considered in policymaking in the field of public health of military communities for control strategies and preventive programs. In future studies, the risk factors and nonecological parameters should be addressed in hotspot regions.

Background and Aim: Evaluation of the performance of these products is mainly based on their efficiency in numerical removal of particles in the range of different sizes. While the most important features of filters are the dust holding capacity, and the ability to remove the mass of particles with different densities, fewer studies have addressed this issue. Therefore, the present study evaluates the dust holding capacity of nanofiber media and its ability to capture synthetic dust to determine its ability to remove the mass of particles with different densities. At the same time, the initial efficiency of the fabricated media in the numerical removal of particles is also examined. Methods: For producing nanofibers, a 16% w/w electrospinning solution of polyacrylonitrile polymer was prepared. The initial efficiency test in numerical removal of particles was performed according to ISO 29463 standard and the BS EN 779 standard was used for synthetic dust capture or arrestance test. Morphological characteristics, diameter, and surface porosity of the produced nanofibers were investigated using scanning electron microscopy. Results: The investigation of the numerical removal of particles by the produced media showed that the average initial efficiency for collecting particles from 10 to 1000 nm was 72. 06 ±,19. 62%. The results of the arrestance test showed that with increasing the mass of injected particles in different loading stages, the media pressure drop also increases. The dust holding capacity and the arrestance of the media for the final pressure drop of 265 Pascal were calculated to be about 180 mg and 99. 86%, respectively. The total mean of arrestance was calculated to be about 99. 86% after 6 loading steps. The morphological characterization of the produced nanofibers showed that the average diameter of the fibers was 380 nm with a coefficient of variation of 1. 20, the morphology of nanofibers was non-uniform, and the surface porosity was determined to be 51%. Conclusion: Proper collection efficiency and dust holding capacity, along with the low thickness of nanofiber media, make their applicability more specific in air filtration properties.
