The aim of this research is to study the dependency of students on social networks based on demographic variables. This applied and quantitative research carried out in survey design. The measurement tool for the study was a social networks addiction subscale adopted from questionnaire of Arslan & Kırık (2013). The reliability of tool based on Cronbach's alpha was 0.932. The content validity of tool was measured by view of specialist and construct validity was measured by factor analysis. The population of the study was 4771 undergraduate students at Azarbaijan Shahid Madani University and the sample size was 368 cases based on stratified random sampling method. SPSS software was used in descriptive and inferential statistics. Based on Pearson correlation test, the relationship between students’ dependency on social networks and Internet/social network rate of usage at 99 percent confidence level was positive and significant. Based on independent t-test, there was a significant difference in students’ social network dependency based on accommodation type. Based on ANOVA test, there was significant difference at 95 percent confidence level based on domain of study. Students’ dependency on social networks was in midpoint level. The students, who had further daily Internet or social network usage, had more dependency on networks. Students’ dependency on social networks with different levels of academic achievement was moderately similar. Dependency on social networks among two groups of students (dormitory/humanities domain) was more.

The present study is going to evaluate the relation between knowledge management processes and job performance of employees in university of Tehran. The research’s sample includes 105 employees of Tehran university (21 men and 84 women) using the random sampling and applying the Cochran formula. Besides, research’s data was gathered through performance appraisal checklist and knowledge management questionnaire. The analysis of information was done by using statistical methods (T -test, Anova , U Whitney, mean and Pearson correlation coefficient). The findings of the study showed that the status of knowledge management among employees is lower than the supposed mean and that the job performance is above average. Evaluation of knowledge management and job performance among demographic variables: gender, age, educational level and history of serving demonstrated that only the age with knowledge management and also age, sex with job performance showed a significant difference. The results of the correlation coefficient between the components of the knowledge management and those of job performance indicated that the only significant correlation was found between the components of knowledge acquisition and the components of job performance (task and context performance) and among other variables no significant correlation was discovered.
