Each patient has renal failure in any dialysis with high water volume, which is in direct contact with the patient's blood. The presence of any chemical and microbial contamination in water used in homodynamic devices can be very dangerous for these patients. The purpose of this study was to determine the efficiency of reverse osmosis open systems in improving the water quality used in the preparation of liquid dialysis.

In this cross-sectional study, a descriptive study was carried out to evaluate the microbial and chemical parameters of the dialysis center of Shahid Beheshti Hospital Qorveh and three times at the end of each season in 1396 on 18 samples including reverse osmosis and the resource is done. The method of conducting the tests from standard book and independent t-test was analyzed for data analysis in SPSS version 20 software.

Reverse osmosis system significantly reduced the amount of sodium, magnesium, calcium, nitrate and sulfate. The average of chemical parameters is significantly less than the standard limit. The results of the test for reverse osmosis efficiency showed that there is a significant difference in water quality before and after the purification system in the hospital...

The average of all compounds measured in two laboratories inside and outside of the province was lower than the standard for evaluation of microbiological and chemical indices. It does not have microbial and non-clinical chemical and is a standard AAMI radar standard.

 Activities aimed at achieving the goals of the resistive economy by students who are influential groups of the country will lead to the development of society in various aspects such as socio-economic, cultural and even religious. The purpose of this study was to evaluate students' knowledge and practice in relation to resistive economics.

This descriptive study conducted among 691 students of medical, dentistry and paramedical schools in five consecutive periods from 2013 to 2016. Samples were collected in simple method. The data were collected by a researcher-made form, comprised of two sections of personal data and questions about resistive economics. Data processing was performed using descriptive statistics.

Students' awareness of resistive economy over time increased from 42.4% in the second half of 2013 to 93.4% in the first half of the 2016. Students' performance on the resistive economy showed that their performance fluctuated over time, but changed over the course of 5 consecutive periods from 8.8 to 8.4%. The question about the person responsible for the issue of resistive economy indicated that most students considered the responsibility of the people and governmental authorities.

Although the results indicate an improvement in students' awareness and about resistive economy, their performance status does not seem satisfactory. Therefore, it is imperative that universities apply specific programs for greater participation and improvement of students' performance in national and social issues.

The electronic and electrical wastes are special types of wastes, the main components of which include capacitors, transistors, ICSI, electronic circuits, cathode and anode components, and have toxicity, pathogenicity and stability in the environment and even in the body of organisms. , Corrosive installations and equipment, and the like. Accordingly, the purpose of this study is to investigate and identify the factors affecting the release of these metals and especially the thallium element in the surrounding environment.

In order to study the effect of different factors such as temperature, pH, hamic acid and time on the release of thallium from such waste to aquatic and terrestrial environments has been studied. For this purpose, the selected parts were analyzed and examined.

The results indicated that in the aqueous medium, the amount of thallium penetration increased at a very acidic and very alkaline pH. Also, in an aqueous medium, the temperature increase increases the penetration of the thallium element in the environment, and the effect of the contact time parameter is also proportional to the pH variation.

Increasing of moisture in the soil enhances the release of thallium in the environment.

The prevalence of skin cancer is increasing all over the world, especially in Iran; however, this cancer is preventable by several protective measures like lifestyle changes. This study aimed to investigate the effect of lifestyle education on preventing skin cancer behaviors in Urmia midwifery students.

In this quasi-experimental study, 100 midwifery students (50 in the intervention group and 50 in the control group) were enrolled. The research sample was selected using stratified ran-dom sampling method. The data gathering tool was a researcher-made questionnaire. Educational inter-vention was administered in three 45 min sessions. The study data were collected through direct inter-views once before and then three months after the intervention. The obtained data were analyzed by the Independent t-test and paired t-test.

The mean scores of knowledge and attitude in the intervention group increased compared to those in the control group after the intervention. Also, some difference, but not significant was observed in the control group. Finally, the mean scores of skin cancer prevention behavior in the intervention group signifi-cantly increased compared to the control group.

Regular and planned education can be effective in promoting skin cancer prevention behaviors.

According to the researchers' recommendations for applying the Health Belief Model (HBM) in smoking prevention, increasing smoking among students and the role of attitude in smoking prevention, this study was implemented aimed to determine the effect of educational intervention based on HBM on University students' attitude towards smoking prevention.

This was a quasi-experimental interventional study that was conducted in 2016 and among 130 dormitory students of Shahid Beheshti University of Medical Sciences in Tehran (65 in each intervention and control group). Data gathering tool was demographic and background characteristics questionnaire and a valid and reliable questionnaire based on HBM about smoking disadvantage that was completed in two stages before and three months after the intervention. Educational intervention was performed using telegram application and educational messages were sent to the students of the intervention group in 6 sessions. The collected data were analyzed using proportional tests and SPSS software version 18.  

Before the intervention, there was no significant difference between demographic and background variables, and mean scores of all the constructs of HBM in both groups (P>0.05). Three months after intervention, comparing two groups showed that the mean scores of all the constructs have changed significantly in intervention group compared to control group (P<0.05). 

Considering the effectiveness of intervention through telegram application and based on HBM on university students' attitudes toward smoking prevention, it is suggested that research be conducted on the effects of telegram usage on other health problems of university students.

Lice infection as a social issue is one of the common health problems among students. Therefore, the aim of this study was to determine the effect of education based on Health Belief Model (HBM) on preventive behaviors of head lice infestation in students.

This was a semi-experimental interventional study. The study population consisted of 138 students (69 in each intervention and control group) in the sixth grade of primary school in Marivan city in 2017, that were selected by two-stage cluster sampling. Educational intervention was presented at 5 sessions. The data gathering tool was a demographic and Background questionnaire and a researcher-made questionnaire based on HBM and knowledge and Preventive behavior of Pediculosis, which completed in two stages before and two months after the intervention. The collected data were analyzed using SPSS software version 16 and proportional tests.

There was no significant difference between demographic and Background variables between the two groups before intervention (P>0.05). Two months after the intervention, there was a significant difference between the mean scores of the knowledge and the perceived susceptibility and perceived barriers in the intervention group (P<0.05), but in other constructs of the HBM, as well as behavior, were not significantly different, before and after the intervention (P>0.05).

Despite the significant increase in knowledge and Perceived susceptibility and perceived barriers structures, the educational intervention did not have a significant effect on the adoption of preventive behaviors of head lice infestation.
