The main purpose of this study is to investigate the information-sharing behavior of librarians of public libraries in the Khorasan region on social network sites. This research was an applied one for which an analytical survey method was employed. The research population consisted of librarians of public libraries affiliated with the Public Library Foundation. Based on Cochran's formula, the sample size was 231 people. A total of 150 people (65%) completed the online research questionnaire. Findings show that about 42% of librarians have used social network sites for more than three years, and nearly half of them use these networks for half an hour to an hour during the day. Librarians have performed significantly below the desired level of information sharing on these networks. The results also showed that there was no significant difference in the information-sharing behavior of male and female librarians as well as librarians of different educational levels on social network sites. But there was a significant and positive relationship between both indicators of trust (trust in network and trust in network members) and librarians' information sharing behavior on social network sites.

User participation behavior when using cyberspace is influenced by several factors. In recent years, researchers have studied the behavior of users and while identifying the factors affecting it, have proposed various models to explain how they participate. The purpose of this article is to identify the impact of attitude on the behavior of cyberspace users. Participatory behavior of users means using the facilities provided in cyberspace, including communicating, exchanging ideas, sharing text and images, and in general, interacting with other people present in cyberspace. This research is methodologically in the combined research group and initially, the qualitative approach and deductive content analysis method were used to design the model, and the quantitative approach and structural equation modeling method were used to test and validate the model. The content of the research was collected using a semi-structured interview technique with experts. Findings indicate the effectiveness of users' participatory behavior from the variable of attitude directly and indirectly and through the mediating variables of desire and intention directly. Findings indicate a positive and significant relationship between the factors of attitude and desire and intention, which was explained in previous research.

The purpose of this study was to survey the effect of the role of willingness to share knowledge of the staff on the effective strategic areas of team sports federations. The method of the present study was descriptive and survey type which is applied based on the purpose. The statistical population of the study includes the employees of the national team sports federations (N = 350) and 183 people were selected as a statistical sample using the Morgan table and random sampling method. The collection tool of this research is based on the strategic areas questionnaires of Moghimi Organization (2015) and Taylor and Todd's (1995) Tendency to Share Knowledge Questionnaire. The reliability coefficient of both questionnaires was above 0.7, which indicates the acceptable reliability of the questionnaires used. Data analysis was performed using descriptive statistics indicators such as frequency distribution and inferential statistics and structural equation modeling with the partial least squares (PLS) approach. The results showed that the tendency to share employees' knowledge affects the strategic areas of team sports federations. The tendency of employees to share knowledge has a significant effect on culture with a path coefficient of 0.289, on infrastructure with a path coefficient of 0.370, on capability with a path coefficient of 0.457, on resources with a path coefficient of 0.459, on information with a path coefficient of 0.710. The findings also indicate that the value of GOF in this study is equal to 0.257, which indicates that the research model has a higher than average fit. According to the results, managers need to provide conditions in sports federations so that knowledge sharing is well developed among employees.

The aim of this study was to investigate the functional role of knowledge management in the relationship between the quality of teamwork and organizational agility. The research is descriptive-survey and cross-sectional (2020). The statistical population is 120 employees of the Marivan Education Department. The library and field method (questionnaire) was used to collect data. By the three standard questionnaires of Hogel and Gmuinden teamwork (2001) and the standard questionnaire of organizational agility of Zhang (2001) and the researcher-made questionnaire of knowledge management based on the Probst model, their validity was confirmed by experts, and their reliability was confirmed by Cronbach's test. Structural equation modeling using LISREL software was used to analyze the data. The results showed that the given model with RMSEA values = 0.058 and χ ^ 2 / Df = 2.43 fits reasonably and appropriately. On the other hand, the factor load of the variables in the standard mode was more than three tenths, which indicates a positive correlation between the variables. In addition, the amount of factor load was in the case of significant coefficients of the variable quality of teamwork with organizational agility (3.60); the relationship between team quality and knowledge management (4.65), and the relationship between knowledge management and organizational agility (5.49). The significant point of the study was that the relationship between team quality and organizational agility with the functional role of knowledge management has increased from 3.60 to 5.49, ie knowledge management has well mediated the role of teamwork quality and organizational agility.

In the last few months, and especially in the last few weeks, the outbreak of Covid-19 (Corona) has become an international crisis. Regardless of the consequences, one of the most tangible results is the impact of formal education systems and the closure of schools in 188 countries. Therefore, at this point in time, public education in countries should be implemented in homes instead of schools. One effective way to solve this problem is to create mobile learning areas. Therefore, the study of the effect of teachers' media literacy components on improving the mobile learning process during the Corona outbreak in the country was determined by this study. The present study is based on the purpose and style of descriptive data collection, in terms of application type and in terms of quantitative method (in order to answer the first question, the research method is documented, and to answer the second question, the descriptive-survey method is used). The measurement tool in the second stage of the research was a researcher-made questionnaire whose validity was confirmed by experts and its reliability was confirmed by Cronbach's alpha coefficient of 0.864. In this study, the statistical population was formed by all principals and teachers working in schools in Tehran in the year 1399-1389, and the statistical sample in the quantitative section was selected by the available method with a volume of 102 people. In order to answer the questions of the present study, descriptive and inferential statistical methods such as the chi-square test have been used. The results showed that from the perspective of school principals and teachers, the three main components of media literacy: the main component of access and use of cyberspace with 5 sub-components, the main component of critical view of virtual media with 5 sub-components, and the main component of virtual media production with 5 sub-components, were identified and prioritized as the most effective components of media literacy on improving the mobile learning process during the Corona outbreak in the country.

COVID-19 as an infectious disease has been declared the sixth public health emergency of international concern. The disease caused not only the risk of death from the virus's rapid spread but also severe psychological consequences. The aim of the current study is to investigate the psychological impact of the coronavirus epidemic among college students. the study is a descriptive correlational study. The study was conducted in the summer of 2020 and a total sample of 801 participants recruited from universities all over Iran answered online questioners of Depression anxiety stress scale-21 (DASS-21), Generalized anxiety disorder scale-7 (GAD-7), coronavirus anxiety scale, and demographic information. To analyze the data, chi-square, independent T, and variance analysis were used. The results showed that the mean of coronavirus anxiety was 13.77, the mean of anxiety was 6.83, the mean of stress was 6.68, also, the mean of generalized anxiety was 4.85 and finally the mean of depression was equal to 5.54. The results also showed that general anxiety and generalized anxiety were able to predict coronavirus anxiety among study participants. Also, results of the T-test and ANOVA revealed that individuals who had a contact history with the virus, or one of their family members was infected showed more severe levels of anxiety in comparison with individuals who had not. Moreover, participants who lived with friends experienced more anxiety symptoms (p< 0.001). the findings of the present study showed that COVID-19 caused public, psychological problems which are more severe in individuals who had a history or contact (through their family) with coronavirus or lived with their friends.

The purpose of this study is to use ontologies in the information retrieval of digital collections with an emphasis on images. The present research is of applied type and has been done by library method and systematic review of resources with an analytical approach. Using this method, the sources were collected around the research axis and selected for a more detailed review, and finally, the sources were reviewed according to specific and systematic instructions. In this method, all research in the field of ontology and its effect on image retrieval has been reviewed. The research findings show that image retrieval techniques, considering the backgrounds, include: text-based image retrieval, content-based image retrieval, composite model image retrieval, and semantic (conceptual) retrieval that used related feedback schemes to improve performance as well as the accuracy of the image retrieval process.Most of the researched studies have emphasized the necessity of using ontologies in digital collections. Therefore, in the current situation, we are moving towards the Semantic Web in order to organize digital images that deal with various structural and linguistic problems such as ambiguities, doubts, and human metaphors for the machine, and the use of ontologies. It is very effective in improving accessibility and retrieval accuracy.
