Background and Objective: Overexposure to electromagnetic waves produces by computer cause health disorders by users. This study was performed to determine the employer's exposure risk to electromagnetic fields from monitors of computers in north of Iran Methods: This descriptive-analytical study was performed on 100 of computers using by 100 employee users (69 males and 31 femals) with the mean age of 40.83±7.37 in Gomishan county, Golestan province in north of Iran during 2018. The intensity of the magnetic and electric field caused by computers was measured at 30, 50 and 60 cm intervals and in four directions from the front, back, right and left side of the monitor using SVENSK standard method. The intensity of fields was measured by TM-190 instrument. Data were compared with OEL (Occupational Exposure Limit), MPRII and TCO (The Swedish Confederation of Professional Employees). The NIOSH (National Institute for Occupational Safety and Health) standard questionnaire was used to assess the side effects of working with computers. The health problems in employee users were recorded. Results: The mean±SD of the intensity of the electrical waves was 103.63±33.62 v/m that was less than the standard values. The mean±SD of the intensity of the magnetic waves was 0.1±0.09 mA/m that was higher than the TCO, MPRII standard values and less than OEL. The maximum magnetic-field invasion from the standard range with an average of 157.04 mA/m is on the front of the monitors, at a distance of 30 cm and the lowest of them with a mean of 19.2 mA/m for the off-mode computer and at a distance of 60 cm from the mantle. There was a significant difference between the time of working with computer in the day with burning eye, headache and eye fatigue. There were no significant difference of clinical symptoms in men and women and fatigue syndrome. Conclusion: The electrical waves of monitor of computers were lower than standard limit in all studied conditions, but the magnetic waves were much higher than standard limit.

Background and Objective: Collection and disposal of waste has an important role in public health. Isolation and separation procedures at the origin is considered as one of the most important and least costly methods of isolation and separation of waste. This study was aimed to culture and educate those involved in recycling and waste reduction in the Kalaeh City using two educational methods. . Materials and Methods: This semi-experimental study was conducted in Kalaleh City. In the social and cultural context, Kalaleh was divided into six regions. Using cluster sampling, regions were selected randomly. In each area, 120 samples were used. The first group was face-to-face trained and the second group received training through the training package. Waste collection period was 60 days. After this time, the questionnaires were again filled up and the impact of teaching methods were investigated. Results: Face-to-face training resulted in increasing waste separation from 70.8 (before training) to 95%. Whereas, this figure in the group receiving training package increased from 57.5 (before training) to 86.7%. Waste recycling rate was between 0.6 to 1 Kg per person per week. These wastes included paper, glass, plastic, and metal containers. On average, the waste recycled in face-to-face training group and training package group was 91 and 83 Kg per week. Conclusion: Knowledge, attitude and cooperation in waste separation increased after training in both groups. However, in the face-to-face training group, the knowledge and participation in waste separation was more compared with training package group. Continuous training and organizing waste separators could be helpful to re-use waste. It causes less pollution of the environment, reduce the transmission of diseases associated with non-systematic disposal of solid waste, reduce costs and increase awareness about the problems and issues of solid waste, and reduce the solid waste volume.

Background and Objective: Different coagulants including aluminum sulfate (Alum) and Polyaluminum Chloride (PAC) are used for water clarification process and deposition of colloidal particles. The use of coagulants causes some residual aluminum in water. The residual aluminum higher than 0.2 mg/l, has adverse effects on human health and environment. This study was conducted to determine the amount of residual aluminum by applying Polyaluminium chloride and aluminum sulfate for turbidity removal from turbid water. Methods: In this laboratory study, the experiments were run by using synthetic water having low (10-30 NTU), medium (100-130 NTU) and high (200-230 NTU) initial turbidities. Synthetic turbid water was prepared by adding stock kaolin suspension into distilled water. Samples of 1 liter of water were poured on 6 Jars. After adjusting of pH, coagulant was added into each beaker at various doses and agitated at 100 rpm for 30s. The mixing speed was then reduced to 20 rpm and kept for another 15 minutes. The suspensions were left for sedimentation and after 30 minutes of sedimentation, clarified samples were collected from the top of the beakers. Residual turbidity and residual aluminum was measured. The residual turbidity was measured using a Turbidimeter according to Nephlometric method. The residual aluminum was determined by Eriochrome cyanine R method. Results: Residual alminium in low, medium and high turbidities was 0.006 mg/l, 0.05 mg/l and 0.07 mg/l by applying Polyaluminum Chloride and 0.065 mg/l, 0.15 mg/l and 0.22 mg/l by applying alum, respectively. There was a significant correlation between dosage of Alum and Polyaluminum Chloride with residual aluminium (P

Introduction: Quality of life among patients with epilepsy is severely affected by consequences of physical, psychological, social of epilepsy. The aim of present study was to evaluate predictors of quality of life in epileptic patients and to determine the main effective factors. Methods: This is a comparative cross sectional study on 100 epileptic patients and 100 healthy people from patient's relatives who referred to neurology clinic of 22 Bahman hospital in Mashhad. Data were collected through the WHO quality of life (QOL) standard questionnaire. Multiple linear regression analysis was used to determine predictor factors of quality of life in patients with epilepsy. Results: The mean total score of quality of life in two groups of patients and healthy people showed no significant difference. Only in the physical (P<0.001), environment (P=0.002) and social domain (P<0.001) differences were statistically significant. Multiple linear regression analysis showed that age, sex, education level, type of epilepsy, and numbers of seizures in one month are effective factors. In all four domains of QOL, quality of life score decreased by increasing the episodes of seizures. Moreover, females compared with males had higher quality of life scores. Conclusion: Age, sex, education level, type of epilepsy, and number of seizures were important predictors of total QOL in patients with epilepsy. Number of seizures and female gender had higher effect on QOL. Based on our findings controlling numbers of seizures is the key factor in improving the quality of life among patients with epilepsy.
