The main purpose of this study is to identify the information behavior of  IRINN  reporters in finding the subject of reports and using information sources.

The present study is an analytical survey using a questionnaire on the statistical population of 60 journalists active in the IRINN in the summer of 1398. The validity and reliability of information measuring instruments were confirmed by the professors of information science and epistemology and its reliability was calculated with Cronbach's alpha coefficient equal to 0.89. Data were analyzed in two sections: descriptive statistics and inferential statistics.

The results showed that the components of "slow internet speed (average 4.47)", "correct understanding and clear view of the subject to increase confidence" and "search for information to report" are the most important barriers to accessing information. The component "role of family, relatives, friends, neighbors in determining the news subjects of journalists" with an average of 3.04 has the lowest rate.

The results obtained from the study show that factors such as: insufficient information from available sources, ignorance of search methods, unprofessional reporters, limitations of providing attractive news, unpopularity of subjects, tendency to meet the demands of managers Media, lack of use of library and archival resources, lack of field news research, problems of formal and in-service education, lack of diversity and inattention to research are the most important components affecting the correct information behavior of journalists.

The aim of this study was to evaluate the e-learning readiness of medical students of Mazandaran University of Medical Sciences.

The research is of applied type and survey-analytical method. The statistical population included 210 professional doctoral students of Mazandaran University of Medical Sciences who answered the questionnaires by census sampling method of 96 people. The data collection tool was a questionnaire and its reliability was confirmed according to Cronbach's alpha coefficient (0.839). Descriptive statistics, Kolmogorov-Smirnov test and "Student's" and "Friedman" tests were used to analyze the data.
