Background and Aim: Relative generality and precision are two important criteria for measuring the efficiency and performance of information retrieval systems. The aim of this study was to compare the integrity and location of evidence-based bases in the digital library of Hamedan University of Medical Sciences in data retrieval of diabetes.   
Methods: The design of this research is cross-sectional, survey, descriptive and is an applied type. Preparing a list on clinical questions here was done as referring to the Diabetes Center in Semirom for 5 months. The following keywords were searched on databases: Up To Date, Clinical Key, Embase, Cochrane, Ovid, and PubMed Tool. The data were analyzed using the descriptive and inferential statistics in terms of tables, diagrams, chi-square test.
Results: The findings showed that both Ovid and Clinical Key databases recovered more relevant documents in contrast to other databases Based on the most relevant documents. According to the relevant and relatively relevant documents, Clinical Key, Embase, Ovid and Up To Date databases had the highest recall in contrast to the PubMed and Cochrane databases which possessed the lowest recall. According to the most relevant documents, the Ovid Database has the highest precision while the PubMed Database had the lowest precision. Among the databases, up to date had retrieved the relevant documents.
Conclusion: Ovid possesses more recall and precision among the databases analyzed, but evidence-based resources are generally well-suited to clinical questions in the field of diabetes

Background and Aim: The aim was to investigate the effect of membership in social networks and mental rumination on cognitive flexibility of female law students at Islamic Azad University of Ghaemshahr.

Method: The research method was correlational.    Sample of 70 law students randomly selected by Krejcie Morgan. Instruments used were: 1. A questionnaire to study the effects of membership in social networks and; 2.  Cognitive flexibility questionnaire (Taghizadeh and Nikkhah) and mental rumination scale questionnaire (Taghizadeh).
Results: Results showed that the intensity of the effect of membership in social networks (24.5%) was higher than the intensity of the effect of mental rumination (12.8%). The intensity of the effect could also be seen for all three subscales of the two variables. The results of structural equations to reject or confirm the hypotheses had shown that both variables of membership in social networks (P = 0.001 and β = 0.526) and rumination (P = 0.002 and (β = -0.379) on flexibility Cognitive have had a significant effect that giving the value of the path coefficient could be said that membership in social networks has a positive effect and mental rumination has a negative effect.     
Conclusion: Membership in social networks has had far greater and more destructive effects than mental rumination on students' cognitive flexibility, and it could be said that both the variables of membership in social networks and mental rumination have affected cognitive flexibility.

Purpose: The purpose of this research is to investigate the effect of increasing positive mood and academic-emotional, behavioral and cognitive enthusiasm on the decision-making power in interacting with information in technical engineering male students of Noushirani University.
Methodology: The research method is descriptive and correlational. The statistical sample in this study is 70 available samples from Noushirani technical engineering male students in the academic year 2019-1400. The sampling method in this research is simple random. To determine the sample size in this research, the Kargesi Morgan table was used. To collect data, the questionnaire of effective factors in increasing positive mood and the academic enthusiasm scale - behavioral, emotional, and cognitive enthusiasm and the decision-making power questionnaire were used. Data analysis was done using software (PLS).
Findings: The results indicated that the effect of positive mood on decision-making power had a significant value of 7.743, which is significant at the 95% confidence level. The effect of academic enthusiasm on decision-making power has a significant value of 8.579, which is significant at the 95% confidence level, so the researcher's claim is confirmed with a probability of 95%. Also, all three components of this variable, including behavioral passion-emotional passion, and cognitive passion, have had a positive and significant impact on decision-making power at the 95% confidence level. Based on this, it can be said that the two variables of academic enthusiasm and positive mood together affect decision-making power by 86.9%.
