Abstract	Mild cognitive impairment (MCI) conversion prediction is a vital challenge in the area of Alzheimer’s disease (AD) as it could determine possible treatment pathways for AD patients. In this work, we presented a robust MCI conversion prediction framework based on the 3D-Zernike Moment (3D-ZM) method that generates statistical features (e.g., shape, texture, and symmetry information) from 3D-MRI scans and improved dynamic particle swarm optimization (IDPSO) that finds an informative sub-set of Zernike features for MCI conversion prediction. We quantified the efficiency of the proposed prediction framework on a large sample of MCI patients including 105 progressive-MCI (pMCI) and 121 stable-MCI (sMCI) at the baseline from the ADNI dataset. Using the proposed MCI conversion prediction framework, pMCI patients were distinguished from sMCI patients with an accuracy exceeding 75% (sensitivity, 83%, and specificity, 68%), which is well comparable with the state-of-the-art MCI conversion prediction approaches. Experimental results indicate that the 3D-ZM method can represent informative statistical patterns from 3D-MRI scans and IDPSO has a great capability to find meaningful statistical features for identifying MCI patients who are at risk of conversion to the AD stage.

Abstract	BACKGROUND: A teacher's job stress is a teacher's experience of negative and unpleasant feelings such as discomfort, anxiety, depression, and anger that are caused by some aspects of a teacher's work, and has unpleasant consequences. This study aimed to determine the relationship between spiritual intelligence and social intelligence with job stress in teachers of Marivan County, Iran, in 2016. METHODS: This was a cross-sectional descriptive-analytical study. The population of this study was education teachers of Marivan County; using a sample size formula, 443 of them were randomly selected. Data collection tools were Osipow Job Stress Scale, Spiritual Intelligence Scale, and Social Intelligence Scale. The data were collected in autumn and winter and were analyzed using SPSS software. RESULTS: 70.2% of the samples were men and the others were women. The mean of the teachers' job stress score was 165.43 ± 25.67 (total score of the questionnaire: 300). This score indicates that the occupational stress level of the samples is higher than the average. The mean score of spiritual intelligence of the teachers was 100.70 ± 11.63 out of 116, the total score of the questionnaire. Of the social intelligence total score (36), the mean score of social intelligence was 21.29 ± 4.72, which was higher than the average. CONCLUSION: The results of the study indicated that the occupational stress of teachers was higher than average, and this stress could have different reasons. Educational leaders and planners should look for reasons and factors that affect teachers' job stress.

Abstract	Heat waves and urban heat islands are phenomena that affect human life. The purpose of this study is to investigation the relationship between heat waves and urban heat islands in the Ahvaz metropolis from 2003 to 2018. For this purpose days with a temperature higher than +2 standard deviation ) and lasted at least 2 days, were identified as days with heat wave using the Fumiaki index, to investigate the effect of heat waves on the intensification of heat islands , heat islands for daytime and nighttime days with the heat wave and a normal day with the lowest maximum temperature as a day without heat wave, the occurrence of each heat wave was calculated using MODIS-AQUA data. According to the results, most of the heat waves in Ahvaz which occurred in March 2010, were at the end of the cold period. In terms of continuity, it was 7 days and long-term. findings also showed that in heat wave and no heat wave conditions, often formed on the day the cold island and at night the heat island, but in the heat wave conditions during the day the cold island it has been often more severe than normal days, and at night time the heat island is often more intense than normal day. In general, the occurrence of heat waves has an effect on the intensification of the thermal islands of Ahvaz in both hot and cold months. these conditions have been more noticeable in warm months than cold months.

Abstract	Background and Aim: One of the problems of the researchers at the start of the research is the estimation of sample size and selection of an appropriate sample of the population. Small sample size can damage research credibility and lead to loss of money and waste of time. In contrast, large sample size can lead to increased workload, cost, and lack of proper feedback. The purpose of this study was to evaluate the sample size in various medical studies. Materials and Methods: In this study, after determining the types of studies, various sources (books, journals, articles, etc.) were searched and different sampling methods based on the type of variable, were determined and classified on the basis of the corresponding formulas. Among the different methods, we extracted the best formulas and methods on the basis of the type of study and other important and confounding factors. Result: Various studies have shown that several factors affect sample size including effect size, power of the test, significance level, the maximum error of measurement, ratio, and variation of the trait. In this study, it was shown that in regression models, the effect of the correlation coefficient between variables should be controlled and the sample size should be estimated by considering and balancing the generated dispersion amount. Also, the size of the effect of the most important indicator and the test power is strongly influenced by the sample size. Conclusion: In most similar studies, it has been shown that for estimation of the effective and valid sample size, the error rate should be low and the test power should be high, and also the effect values, level of significance and dispersion, and the correlation between the variables should be controlled.

Abstract	Among various techniques available for leachate treatment, nano-photocatalytic-based techniques have been considered as efficient. The photocatalytic leachate treatment using nanoparticles of zinc oxide doped with molybdenum oxide was performed in the presence of sunlight at a laboratory scale. The molybdenum oxide doped ZnO nanoparticles were synthesized. The properties of nanoparticle were analyzed by using FTIR, SEM, and XRD. Then the parameters such as pH (3, 5, 7, 9, & 11), concentration of nanoparticles (0.5, 1, 2 and 3 g/l), concentration of leachate with dilution (1:10, 1:25, 1:50 and 1:100), and contact time (15, 30, 45, 60, 90, & 120 min) were measured to determine the removal of COD and turbidity. The analysis indicated that nanoparticle size was appropriate and acceptable. Electron microscope images also showed that the nanoparticle shape was hexagonal. The optimum value of pH was 5. It was found that increasing the concentration of nanoparticles enhances the efficiency of the process, the concentration of nanoparticles from 0.5 to 2 g/l at 60 min of contact time, and the efficiency from 34.8 to 55.6%, and increasing in contact time decreases the COD and turbidity leachate. Enhancing the initial concentration of leachate reduces the treatment efficiency of landfill leachate.

Abstract	Background and aims: Growth of labor productivity is one of the most important factors of development and competitiveness of the economy. In targeting economic growth, a significant contribution is being made to improve productivity. Labor productivity in a community has several socio-economic dimensions. Since labor productivity reflects the level of production and performance of people in the community, it is therefore very close to general well-being, because when a society produces its population, it has more prosperity and resources than a lower-productivity economy. The situation of labor productivity determines the success of an economy in competing with other economies, with lower finished product costs and lower prices that may not be feasible for a low productivity economy and exit from market competition. Worker productivity in a community is one of the key multivariate variables, which is always a matter for the attention of community planners and policymakers. The importance of this issue for developing economies, such as Iran, is twofold; in fact, one of the main priorities of the Iranian economy is to improve productivity, which is, of course, in large-scale programs of the community, such as development plans (in development programs, it is usually said that one-third of economic growth will be achieved through improved productivity) Or general policies such as resistance policies and policies to reduce dependence on oil and enhance the competitiveness of the Iranian economy. Although productivity improvements in the Iranian economy have always been seriously addressed, significant improvement in productivity, especially compared with other economies, has been a mystery of numerous theoretical and empirical studies. One of the reasons for failure to improve the productivity indicators in Iran is that less attention has been paid to the relationships and determinants of productivity. Hence, effective factors on improving the productivity, has been the focus of attention of researchers in different ...

Abstract	Background and Aim: The aim of this study was to compare personality characteristics and coping strategies between the patients with irritable bowel syndrome and normal individuals. Material and Method: In this cross sectional study we selected 200 people (100 irritable bowel syndrome patients and 100 normal individuals) on the basis of convenient method. We used two questionnaires including the NEO- Five Factor personality Inventory and Lazarus- Folkman coping Questionnaire for data collection. Data were analyzed by t-test and Mann- whitney U Test. Results: The results showed that the mean scores of neuroticism factor in the patients with irritable bowel syndrome were higher than those in the normal individuals. While the mean scores of extraversion and conscientiousness factor in the normal subjects was higher than those in the patients with irritable bowel syndrome. There were no significant differences between the two groups in openness and agreeableness. Data showed that normal individuals compared to the patients with irritable bowel syndrome, used more problem- oriented coping styles. There were no significant differences between the two groups in regard to the escape-avoidance variable. Conclusion: The results showed that IBS was affected by personality characteristics and coping strategies. Study of these factors can have many applications in the fields of research, etiology and treatment of this disease.

Abstract	Background: Human papillomavirus (HPV) can infect the epithelium of the esophagus, but so far there is no reliable and comprehensive evidence about the prevalence and association of HPV with esophageal cancer in Iran, as high incidence region. This study aimed to evaluate the prevalence and association of HPV with esophageal squamous cell carcinoma (ESCC) in Iran. Methods: Relevant English and Persian articles published up to Aug 2017 and indexed in databases were reviewed. Frequency of HPV genotypes in ESCC cases and controls was surveyed according to regions of Iran. Data were meta-analyzed with random effects models using Comprehensive Meta-Analysis software. Results: Overall, 14 studies were eligible including 1444 samples (1062 ESCC cases and 382 controls). HPV was positive in 269 (25.32%) of 1062 ESCC cases and in 65 (17.01%) of 382 controls. Total prevalence of HPV in both groups was estimated 0.256 (95%CI, 0.208%-0.310%). The prevalence of HPV-16 and HPV-18 was estimated 0.121 (95%CI: 0.087-0.183) and 0.046 (95%CI; 0.023-0.088), respectively. The difference in HPV prevalence in different regions of Iran was statistically significant (Q=18.20, df =4, P=0.001). In 6 case-control studies, the pooled odds ratio was estimated 1.99 (95%CI; 0.916-4.315). Conclusion: High-risk HPVs were observed in ESCC cases and controls from different regions of Iran. The odds ratio indicates that the HPV infection in ESCC cases was approximately 2 fold more than the controls. More case-control studies in other populations with larger sample size are necessary.

Abstract	Among the pharmaceutical compounds, antibiotics have been paid specific consideration, due to their acute and chronic toxic effects on organisms. Amoxicillin (AMX) is used widely for treatment of bacterial infections. About 80% of amoxicillin excreted unchanged and enters the aquatic environment through different routes including disposal of municipal wastewaters, hospital wastewaters and farm wastewaters. In this study degradation of amoxicillin by UV/Na2S2O8/FeS2 process was evaluated. According to the results, the R-squared and adjusted R-squared were 0.9877 and 0.9828, respectively. The AMX removal efficiency was 93% at optimum conditions. Thus, UV/Na2S2O8/FeS2 process is a useful process for amoxicillin removal. Keywords: Amoxicillin, Box-Behnken, UV/Na2S2O8/FeS2
