Background and Aim: This study aims to explore the concept of information culture, and survey its status among the faculty members of Ferdowsi University of Mashhad.

Method: This research is applied research that conducted via survey research. Population included faculty members of Ferdowsi university of Mashhad that 250 of them were selected via random sampling. A questionnaire based on (Choo et al., 2008) model were used for data collection. This questionnaire including six dimensions: information integrity, information formality, information control, information transparency, information sharing, and proactive use of information. Before collecting data, validity and reliability of the questionnaire was confirmed.

Results: The results showed that, from the perspective of faculty members of Ferdowsi University of Mashhad, information culture and its dimensions are not desirable at the university. Among the dimensions of information culture information sharing has highest average and information transparency has the lowest average. Also the results show information culture pattern of the Ferdowsi University of Mashhad is Relationship-Based Culture. The relationship between demographic variables and information culture also showed that there is a significant relationship between gender and field of study with some dimensions of information culture.

Conclusion: survey the information culture as an empowerment variable that influence information behaviors and programs in organizations is essential, Because of the important role of information in organizations. Moreover, information culture is a new subject that addressing the new research area for further research, especially in the field of knowledge and information science.

Background and Aim: The aim of this study was to measure the overlap of 4 local Persian search engines of Parsijoo, Yooz, Parseek, and Rismoun and to compare the capabilities of these engines in covering indexable web.
Methods: This was an applied and evaluative research. To collect data, a keyword-based method was used. First, the selected keywords were entered into the search engines and then a sample was extracted of the retrieved records. Finally, based on the existence or absence of these records in the search engines, the necessary data were gathered. Accordingly to analyze the data, inferential statistical methods were used.
Results: The relative overlap of the Parseek compared to that of Parsijoo and Parsijoo's one compared to Yooz was 26 percent on average and Parseek had the most recall. Rismoun had not any common records with the other investigated search engines. Three search engines (Parseekc, Parsijoo and Yooz retrieved 27 common records out of 225 recalled records; there was a significant difference between the relative overlap of the 4 search engines. Also, on average, Parseel, Parsigoo, Yooz and Rismoun covered respectively 38, 31, 26, and 6 percent of the indexable web. There was a significant difference between the coverage of the 4 search engines.
Conclusion: It seems that each search engine has a different indexing policy, and users need to search for more than one search engine to get comprehensive information about an issue. It can be predicted that by foraging in two search engines, Parseek and Parsijoo, one may access 70 percent of the indexable web.

Purpose: the aim was to identify users' search strategies and the rate of using search strategies on the web.

Method: It is a practical survey. The statistical population included all the postgraduate students in the first semester at Ferdowsi University of Mashhad. 95 students were selected by stratified random sampling method. To gather the data, log files were used.

Findings: 12 search strategies were identified which was divided into 5 general categories. Iterative evaluation strategy in another tab was a new form of evaluation strategy of results. Among all, starting search strategies were the most commonly used category which were repeated 397 times, and the search results evaluation strategies were ranked afterward, with 321 replications. The category of Simultaneous multiple resource access strategies, with 77 repetitions, were also the least used strategies, but in particular, the recurring exploration strategy, with 21 repetitions, was the least applicable strategy. Conducting correlation test between strategies showed that some of Pearson's correlation coefficients were significant. The strongest relationship was between the starting search strategies and the search result evaluation strategies with a 0.591 correlation coefficient.

Discussion: The results showed that the majority of students used traditional and simple strategies, such as the formulation of search terms strategy and the iterative result evaluation strategy, and they used more complex strategies in few cases. These results showed that the students need to be trained in using strategies.

Background and Aim: Under the influence of various factors, people use different methods and methods to obtain information and express different information behaviors. These behaviors have been introduced in the form of patterns and models of information retrieval by information science experts in recent decades, which can be used in various fields. One of these areas that almost all people are directly or indirectly involved in is the field of treatment and medicine.   
Methods: This paper whit quasi-experimental examines the Analysis of information behavior of psychotherapists in the process of diagnosing and treating mental disorders based on the Kuhlthau information search process model. The population of this study is psychologists and psychiatrists with more than two years of treatment history. The sample selected from this group also includes 30 therapists who entered the competition through a public call as a top therapist using a simple sampling method. 
Results: The findings show that the sequence of therapists' movements is in accordance with Kuhlthau's opinion and they perform a repetitive movement in the diagnosis and treatment process, but the level of presence of therapists (time spent) differs at different stages from the model considered by Kuhlthau. The findings also showed that variables such as treatment history, field of study, and gender could influence the behavior of therapists. On the other hand, the relationship between the information of the therapists' information behavior and variables such as information literacy, state anxiety and trait, specialized knowledge and self-assessment of therapists was significantly evaluated.    
Conclusion: The information behavior that a treatment specialist performs in his or her treatment process can be analyzed according to the Kuhlthau model.

Aim: The main purpose was to investigate the students’ information sharing behavior in social network sites with a qualitative approach.
Methodology: An applied research with qualitative approach - A Thematic Analysis method was used.  Population consisted of all the students at the Universities in South Khorasan Province affiliated with the Ministry of Science, Research and Technology who had a  minimum of six months experience in using one of the social network sites such as: Telegram, Instagram or WhatsApp.   A non-probability (non-random), and a snowball sampling procedure was used and 17 persons were interviewed. The semi-structured type of interview was incorporated.
Findings: Results showed that most students’ information sharing was done on Telegram and Instagram, respectively. Eighteen primary codes were provided by  students as motives for information sharing in social network sites. These primary codes were categorized into two main categories (personal and social motives) and seven subcategories. Among all the primary codes of the two main categories, the sub-category of “net-surfing and entertainment” had the highest occurrence. For the types of information shared on social network sites by student, 24 primary codes were obtained. These primary codes were categorized into eight sub-categories and two main categories (knowledge and entertaining information). Among the sub-categories identified, the most recurrently shared types of information were “literary-artistic information” and “scientific-educational information”.
Conclusion: For surfing and entertainments’ own good - information sharing on social network sites could lead to admittance of valuable information. If properly planned, it may function as a suitable platform (available to diverse strata of the society, especially the students, at the lowest possible cost) to attain the best possible practice especially in educational settings.
