Corrosive water solve primery materials of pipes, joints and valves in municipal water distribution systems and home plumbing systems and cause a lot of health, aesthetic and economic problems in water distribution systems. Thus, determination of corrosion potential of drinking water using methods which are feasible and reliable is necessary, and corrosion should be controlled in drinking water for water sanitation and health promotion among citizens. Materials and Methods: This research was carried out to determine water corrosivity or sedimentation potential in Khorramabad city, using corrosion indices. In this project 50 points as samples in two stages in the Summer and Autumn seasons were determined, and amount of corrosion indices, including Langelier Indice, Ryzener indice, Aggressive indice and Pokurious indice, corrosivity and temperature, calcium hardness, alkalinity, total dissolved solid and PH were calculated two times within a 3-month interval, then the data obtained from results were analyzed using SPSS software and statistical tests. Results: Results of corrosion indices show that drinking water of Khorramabad is in equilibrium condition and has tendency to corrosion. Calculated corrosion indices are as fllows: Langelier (-0.157), Ryzener (7.86), Aggressive (11.626), and Pokurious indice (7.65). Conclusion: Statistical tests of Pearson and Spearman correlation coefficient don indicate significant relationship between quality parameters with corrosion indices Results of corrosion indices showed that drinking water of Khorramabad is inclined to corrosion.

Abstract
Background: Nowadays, neurofeedback is used as a new method to improve the symptoms of ADHD and epilepsy. The effectiveness of this new therapeutic approach in various disorders has been investigated. The purpose of this study was to compare the efficacy of this treatment in patients with hyperactivity and epilepsy.
Materials and Methods: This study was quasi-experimental with pretest and post test and the control group. The study population comprised all the children with ADHD and epilepsy in Karaj. The sample consisted of 60 infected children (15 indivuduals suffering from ADHD, 15 people with epilepsy and 30 controls) who were selected by the random sampling method. In the pre-test, the behavioral behavior (executive summary) for children was completed. This tool reflects the teacher's view of student behaviors in the field of executive functions. In fact, it provides a tool for screening the performance problems. Executable executive functions in this log include inhibition, flexibility, emotional control, initiation, work memory, planning / organizing, inventory management and monitoring. To conduct the research, the beta / theta program was used for all the subjects. The aim was to increase theta waves and decrease beta waves. After completing 10 sessions (5 weeks and 2 sessions per week), the neurofeedback was run and the log was re-entered. Descriptive statistics (mean and standard deviation) were used to analyze the data and the one-variable covariance method was used to infer the data. Spss version 18 was used to analyze the data.
Results: The findings of the research indicated that the performance scores in the pre-test and post-test of the studied groups were significantly different )P<0.001(. Moreover, the effect of neurofeedback treatment on the improvement of executive functions in the ADHD group was higher than the epileptic and control groups )P<0.001(.
Conclusion: Based on the findings, neurofeedback is efficient but its effect is different in patients with ADHD and epilepsy. Hence, the use of neurofeedback is more effective in improving the performance of ADHD patients. These results can be useful in the field of overactive treatment using novel methods.

Abstract
Background: Trampoline rebound is one of the recent interesting exercises. The present study aimed to investigate the effect of six weeks of trampoline rebound exercises on cardiovascular indices, body mass index, and lipid profile of obese and overweight women.
Materials and Methods: The statistical population of the present quasi-experimental study consisted of 20 obese and overweight women in Zahedan ( (BMI) ≤27.5 kg/m2), and randomly assigned to two groups of exercise (n=10) and control (n=10). The subjects participated in four 90-min sessions of rebound trampoline exercises for six weeks using a trampoline mat. Physiological, BMI, and lipid parameters were measured in two stages of pre-test and post-test. Data were analyzed in SPSS software (version 21) using independent and dependent t-test, as well as an ANCOVA test. A p-value less than 0.05 was considered statistically significant.
Results: The results demonstrated a significant decrease in post-test values of LDL (from 92.90±1.52 to 73.10±3.81), cholesterol (from 182.10±1.96 to 166.30±6.32), triglyceride (from 108.30±1.33 to 95.30±5.35), and body mass index (29.44±1.07 to 27.38±1.02), as well as a significant increase in HDL (from 59.60±2.75 to 77.00± 3.09) and Vo2max (from 45.50±1.31 to 57.80±1.31) in posttest of the training group, compared to their pre-test (P<0.05). Furthermore, there were the same changes in these parameters in the exercise group, compared to the post-test values of the control group (P<0.05).
Conclusion: As evidenced by the results of this study, six weeks of trampoline rebound training had beneficial effects on controlling lipid profile, cardiovascular indices, and body mass index of obese and overweight women. This training protocol is suggested to improve these indicators in the same groups with obesity and overweight, especially for the variety of exercises.
