Information technology (IT) has produced a deep impact on human lives, and the most important aspect of its effect is on education and learning. This study was done for the purpose of evaluating the effectiveness of electronic health information on our Web site http://www.teen.hbi.ir in the promotion of health education and in increasing the capabilities of the students in the use of the Internet. This study was performed on the basis of the information obtained from the questionnaires on selected health issues from 649 students from 3 high schools. Information was collected in 2 steps (pretest and posttest). The t test and Leven's test were used in the statistical analysis of data. Results of the t test showed that educating students through health information Web sites has increased their knowledge by at least 14.5% on environmental health and 48.9% on nutrition and was statistically meaningful in all fields (P=.000) with the exception of mental health. The fact is that the use of IT has become a part of our society and is perhaps the most promising medium for achieving health promotion initiatives.

Background: Web is considered an important tool for formal and informal communication and cooperation among members of the community including researchers. Universities’ websites played a significant role in the development of social structure through the creation of cyberspace. We aimed to evaluate the growth and Webometrics rankings of the country’s medical universities web sites base on interventional approach. Methods: This interventional study assessed Iranian universities of medical sciences’ websites from the periods of Jan 2015, Jul 2015 and Jan 2016. Medical universities websites were ranked based on four Webometrics indicators; PRESENCE, VISIBILITY, OPENNESS, and EXCELLENCE. To enhance the ranking of websites, 4 strategies were introduced in 3 seminars conducted from Jan to Jul 2015. Information needed from these 30 medical universities were obtained from Webometrics Ranking of World Universities based on 4 indicators and were collected in 2 steps (before and after introduction of strategies) Results: About 21% to 70% of the country’s medical universities have increased ranking after the interventions while 9% to 30% obtained a downward trend in their rankings, Tehran University of Medical Sciences obtained the highest rank followed by Shahid Beheshti University of Medical Sciences and the third rank was obtained by Shiraz University of Medical Sciences. Conclusion: The presence of websites play a vital role in the academic community. Doubtlessly, the idea of designing and launching a website without any knowledge of the principles and standards would be problematic and impossible.

Introduction:This study aimed to evaluate the effectiveness of neurofeedback on attention deficit hyperactivity disorder.Methods:This is a quasi-experimental study without a control group. The study population included all children aged 5 to 12 years old affected with attention deficit hyperactivity disorders in Tehran, Iran who were referred to psychiatric clinics and given the diagnosis. The sample included 12 children with attention deficit hyperactivity disorder who were selected based on their availability (non-random sampling). They received 30 sessions of neurofeedback treatment, 2 times per week. Before and after neurofeedback training, the children were evaluated and compared with the use of cognitive assessment system test. Data were analyzed using dependent T-test.Results:The total mean score for pretest was 88.81 while the total mean score for the post test was 82.23. The mean in pretest for attention hyperactivity disorder was higher than the mean in the post test. Moreover, The difference of pretest and post test scores of children affected with learning disorder associated with ADHD was calculated that showed significant (P=0.003).Conclusion:Neurofeedback is effective in the improvement of attention deficit hyperactivity disorder.
