Background: In order to investigate possible consequences of radiofrequency electromagnetic radiations of Wi-Fi modem devices on the information processing speed of university students, six hundred teenagers (14-17 years old) selected by cluster random sampling. They further classified into two groups consisting one control group (without Wi-Fi modem at home; n=200) and experimental group (with Wi-Fi modem at home; n=400). Methods: By means of reaction time machine and KDT test, the speed of information processing was examined. Results: According to our analyses, a significant decrease in the reaction time could be detected in Wi-Fi modem users. The results also revealed that a significant correlation between the uses of Wi-Fi modems with the speed of information processing exists. Conclusion: In conclusion, it has been demonstrated that the everyday radiofrequency electromagnetic field emitted by Wi-Fi devices has the ability to affect the normal functioning of young people's brain.

Background: Drug abuse issue is an internationally serious and important problem viewed from different economic, social, physiological, and psychological angles. It is a multidimensional phenomenon which has attracted the attention of many psychologists, consultants, and social workers. Objectives: The current study aimed to compare the level of adherence to the Islamic lifestyle among addicted and non-addicted young inmates in the prisons of Alborz province. Materials and Methods: The research method of the current study was causual-comparative, and the implementation method was survey. Data were collected by Kaviani`s Islamic lifestyle questionnaire (2011). The statistical population and sampling method: All inmates of the Alborz province prisons formed the population of the study, and 250 subjects were selected by multi-stage cluster method from the population. Results: One-way analysis of variance (ANOVA) showed a significant difference in the level of adherence to the Islamic lifestyle (F = 10.52, Df = 2) among three groups of addicted and non-addicted inmates, and the personnel of the prisons. T-test of two independent groups also showed significant difference in the level of adherence to the Islamic lifestyle between women and men (t =-2.39, P ≤ 0.05). Conclusion: A significant difference was observed among three groups of addicted and non-addicted inmates, and the personnel of the Alborz province prisons in the level of adherence to the Islamic lifestyle, this difference was also significant in terms of sex.

Exposure to electromagnetic fields is considered as a potential hazard for biological systems. The objective of our investigation is the study of probable consequences of radiofrequency electromagnetic fields from Wi-Fi router devices on the short-term memory, and attention's levels. A population consisting of 312 female college students (14 to 17 years old) was elected by cluster random sampling. Teenagers were divided into two groups of control group (Wi-Fi nonusers; n = 138), and experiment group (Wi-Fi users; n = 174). Both groups have been examined using short-term memory tests; selective attention, and also divided attention tests. According to the results, there was no significant difference between using Wi-Fi router devices on levels of selective attentions and short-term memory of the sample students with the control group. However, analyses revealed that there is a significant correlation between the use of Wi-Fi routers and declining levels of divided attentions. Our investigation has demonstrated the adverse consequences of 2.4-2.48 GHz radiofrequency electromagnetic fields of Wi-Fi router devices on divided attention levels of female university students that should be mentioned as a technological risk factor and taken into account by healthcare organizations.

Objective: The aim of this study was to determine Effectiveness Life Review on Life Satisfaction among Adolescents under the Supervision of Qazvin Well-being Center 2012-2013. Method: This study was a quasi-experimental research including experimental and control groups with a pretest-posttest design. The statistical population consisted of all 12 -18 years old male students who were nurtured in Qazvin Well-being Center, among whom 16 individuals were selected through applying purposive sampling method and were randomly divided into experimental and control groups with equal number of subjects. The investigation was done using Diener's (1985) Satisfaction with Life Scale (SWLS) Questionnaire. The experimental group received life review therapy in 6 sessions (90 minutes per session). Data were analyzed by using Analysis of Covariance (ANCOVA), using SPSS software. Results: Results indicated that life review therapy was effective in increasing male adolescents' life satisfaction living in the welfare center. Conclusion: Life review therapy improves quality of life and life satisfaction; therefore, this treatment can be used as an effective method to improve the living conditions of young people.
