The present study is an applied one and is a standard questionnaire based on the HSE model in four dimensions. Descriptive and inferential statistics (Mann-Whitney U test and T-test) were used to describe and analyze the data. The study population consisted of Tarbiat Modarres and Shahid Beheshti University students. Members of Tarbiat Modarres and Shahid Beheshti Central Library were enrolled in the study. A total of 26893 students were selected and the sample size was calculated by Cochran formula. Cronbach's alpha was used to assess face content validity and reliability with acceptable reliability (r = 89%).The findings showed that the components of knowledge creation (3.62%), knowledge sharing (1.16%) and knowledge utilization (3.36%) were better in Shahid Beheshti University than Tarbiat Modares University. And knowledge storage (at university with a mean of 1.96%) is better than that of Shahid Beheshti University. The results of the test showed that knowledge management at Shahid Beheshti University with a mean score of 12/12 compared to Tarbiat Modarres University with a mean score of 43/43 was necessary from the students' point of view.

Introduction: Knowledge management, as one of the achievements of the age of knowledge and information, has strengthened its position by entering the realm of various sciences. Successful organizations today, by acquiring the necessary tools with a knowledge management approach, create good opportunities for optimizing their human and organizational resources. Universities and libraries are the main centers of knowledge production and storage, so the purpose of this study is to review the concept of knowledge management in how it is implemented in organizations (academic and library environments).Methods: This study was conducted by reviewing the sources and internal and external articles with the main subject of knowledge management in educational and library places. Also, search was used on the Internet, as well as scientific sites and databases. The range of articles selected was from 1995 to 2017.Results: The results of studies conducted by researchers in different aspects of knowledge management show a positive and significant effect on the usage of knowledge management components with important variables in universities and libraries. In these researches, the results are more favorable and some are reported to be weak, but in general, all of them consensus in the important role of using the knowledge management process.Conclusion: Universities, and especially university libraries as the main centers and knowledge production and storage organizations, should pay more attention to the knowledge management process and provide the necessary infrastructures to implement it in this regard.

The current research was conducted with the aim of explaining the information-seeking behavior of Allameh Tabataba'i University faculty members based on Belkin Episode Model for use in selective dissemination of information services. In terms of its nature and purpose, it was of an applied type and was done with a survey-analytical method. The studied population consisted of 562 faculty members of Allameh Tabataba'i University, and the research sample consisted of 226 people who were selected by stratified random method. The tool used for data collection was a semi-structured questionnaire. The validity of the questionnaire was confirmed by three subject experts, and the reliability of the questionnaire was estimated to be 0.90 by calculating the Cronbach's alpha coefficient. The collected data were analyzed using SPSS software. The findings of the research showed that the information-seeking behavior of faculty members is at an "average level" and is far from the desired level. As a result, it seems that the design of the databases, the suggested keywords and key phrases of databases, and the capabilities and facilities of the database search system for users for the purpose of conceptual searches should be designed more user-oriented to solve the information needs and improve the information-seeking behavior of faculty members. to help In addition, the faculty members' use of subject thesauruses in order to use specialized terms in order to retrieve information sources that match their information needs can also be a way forward.

IntroductionOne of the most important challenges of context-based information systems with emphasis on cognitive structures is the formulation of receiving and displaying knowledge of cognitive actors empirically in the process of information retrieval interaction. The aim of the present study was to identify the variables of the dimensions of information retrieval context in the interaction process using the framework of the information system and retrieval. of Ingwersen and Jarvelin.Literature RieviewHuman-information interaction is a multidisciplinary problem-oriented research field that studies the interaction between humans and information (with its different forms and purposes). In other words, instead of examining the interaction between humans and technology, which is the field of human-computer interaction and human-machine interaction, or examining the interaction between humans and information agents (i.e., the field of librarianship), it examines the interaction between information and people (Jones & et al, 2006).MethodThe present study is of fundamental and developmental type and has been carried out by Colaizzi phenomenological method (1978) in 7 stages. Data collection tool was using In-depth semi-structured interview with 7 experts in the field of information retrieval to identify variables in the interaction process of information retrieval context. Validity is a tool for collecting and content validity data using the experience of experts and reliability is based on the criteria of Lincoln and Goba (1988) based on Credibility, reliability, verifiability. Description and analysis of information has been compared and validated using the results of systematic review and experiences of experts in the field of information retrieval.ResultsThe identification of the following variables in the context dimensions of information retrieval in the interaction process has led to the stabilization of search, retrieval and access terms that cognitive actors can consider as information retrieval system designers. The variables of comprehensiveness include: identifying the level and nature of information; Knowledge of the problem; Level of knowledge; prior knowledge; mental models; Identifying temporal and linguistic factors to convey meaning and concept; sociological and psychological factors; action effects; Mental presuppositions, taking into account the skill of formulating search terms, can lead to an increase in the efficiency of the retrieval system for overlapping and matching information in the subject coverage of information and documents, the type of metadata standards, the way information is organized. The variables of the obstacle dimension include: the ability to communicate between the information needs and the retrieved document with an objective attitude (information retrieval systems with an emphasis on relevance) and a subjective attitude (use of the system with an emphasis on user characteristics, tasks and environment); attention to the possibilities of the system in the way of organizing information and knowledge; integrated access to information and knowledge; And eliminating human error in the search leads to discarding irrelevant evidence. The variables of the effectiveness dimension include: applicability and accessibility of information according to ethnic and linguistic characteristics, in other words, leveled accesses; meeting mental needs; filling the knowledge and cognitive gap; the extent of using knowledge and experience and transferring it; According to the functions of the information retrieval system, it can help in expanding knowledge and in identifying and correcting the errors of users in accessing information and knowledge, and it leads to the appropriateness of the results in achieving the goals and providing satisfaction with the information services in the system. The variables of the information quality dimension include: the qualitative aspects of the information in terms of influencing the mental structures related to the need; stability of information in its repeatability; the ability to compare and evaluate sources in the ability to cite and reason information; participation in the creation of new knowledge; Finding resources based on the user's knowledge level; It is related to the user experience and leads to an increase in the qualitative level of user recognition and having the desired structure of the information system. The variables of the quality dimension of the time management process include: extraction of resources based on relevance; Meeting the need for information based on information seeking (targeted search); Displaying the steps and process and components of the information system leads to the quality of search processes from the point of view of the user interface.DiscussionAs a result, by searching for the meanings and essences of cognitive actors over time according to experience, in order to reach a common understanding in identifying, discovering and creating a deeper understanding, it led to the description and analysis of the cognitive structures of the information and retrieval system framework of Ingwersen and Jarvelin and finally It provides design and access to information in a networked and systematic way.ConclusionThe approach of cognitive actors in the design of information retrieval system and the role of database designers, user interface designers, information retrieval model designers and search engines are of particular importance in the context of information retrieval. This approach with mental presuppositions with an emphasis on identifying the level and nature of information needs to be recognized and the effects of action over time from the perspective of the user interface. Creating an objective and subjective relationship with interactive and static attitudes reduces human errors in intelligent search and expands knowledge and repairs the knowledge gap, especially by having the desired structure of the information system automatically and by comparing and evaluating resources. The qualitative aspects of the information and process of these steps will be visible and accessible.

Psychology of theology has a great deal of scope and subcategories, and the study of the relationship between these sections as well as the dimensions and structure of each of its subclasses can help to understand the structure of this knowledge. for this reason, this study has been done to explore the Intellectual Structure of the Positive Psychology studies. The present research is applied in a practical way. It uses scientometric techniques and, in particular, the both occurrences of vocabulary method and text mining, to explore the internal structure and subject relations of positive psychological studies. The community of this research is the articles of the positive psychology field indexed at the Scopus base. The total number of articles in the period from 2000 to 2012 was 1086 articles. By extracting related terms from the title, abstract and keywords of the articles and applying the methods of text and rooting, a coincidence matrix with 43 × 43 dimensions was created. Results: The results of this study showed that among the 7 optimized clusters, the cluster 2 with 10 words and the cluster 4 with 9 words, are recognized as the main clusters. The cluster 5 has the largest number of main subjects among the selected concepts, and clusters 2 and 1 have the least distances, which indicates that the connection between the main and minor issues in these clusters is greater. In contrast to cluster 7, it has the greatest distance from most clusters, indicating at least the similarity of cluster threads with other cluster themes. Conclusion: Based on this, the most correlation was found between the internal structure of positive psychology between the concepts of adult, construct, individu, positive psychology and strength in cluster 1 with the concepts effects, chang, develop, educ, emot, model, optim, posit, role and support in cluster 2 is established. In this regard, it is anticipated that cluster 7 with its concepts will become an independent study area in the future.

The internet of things will change our life in future significantly and will make the impossible, possible. A large volume of big data which is produced or taken by Internet of Things (IOT) contains valuable and useful information. By the prevalence of the wireless apparatuses technology such as Bluetooth, detection of radio frequency (RFID), Wi-Fi and data services on telephone, sensor, actuators and nodes embedded in the equipment, Wireless Sensor Networks (WSN) the internet of things has already passed its primary stages and is in the threshold of changing the current static internet into a fully integrated internet. Data mining; too, with no doubt plays a large role in smartness of the system and subsequently, provides suitable services and environment in offering services. Also, data mining techniques are used to cluster nodes and determine cluster head, in wireless sensor networks. This paper introduces the internet of things, architecture and its applications.

Advancing the activities, functions, and structure of each organization are related to information. On the other hand, in the era of innovation, exchanging information with the surrounding environment causes change, transformation, and even evolution. The purpose of this study was to draw the flow of information on the uploading of standard resources in the internal library network of Razi Metallurgical Research Center, as well as validating it using the rate of standard resources usage. The present study is an applied one and the method is system analysis with a hybrid approach. Also, by maintaining the reliability criterion, the scientific accuracy of the research is guaranteed and a criterion for the validity and reliability of the research is shaped. The statistical population includes the national and international standards used in the laboratory and the sample equals each component or element of the statistical community. Data gathering was done by observing the process of work, documentary, and library studying as well as interviewing experts. Finally, with the help of the Microsoft Visio software, the information flow diagrams were plotted and then validated with the rate of standard sources used in the library network of the Razi Metallurgical Research Center. The findings show the process of information flow and the usage rate of the loading of standard resources. The process and the method of exchanging information with the internal and external components of the organization are systematically depicted and designed in the Razi Metallurgy Research Center in three stages including analyzing the existing processes, coding the processes and validating the programmed processes regarding requesting the standard, identifying the need of the customer, inserting the standard in the valid standard folder, and purchasing the required standard. Then throughout a year, the usage rate of the loading of standard resources in the created network is reported. Thus, after the systematic process in the internal library network of the Razi Metallurgy Research Center, the lab staff will send their standard request to the information department if needed, then, the standard will be placed in the center's internal network for a quick and timely access.

The purpose of the study is to orient the Digiqual model with the 5S theoretical framework in digital library concepts. The research type is practical and it was conducted using the analysis of qualitative content method. The validity of the research is a logical one which is based on personal subjective judgment. The reliability of the study is a type of credibility based on counseling the specialists in the field of digital libraries. In the digiqual model, content (information) and community (user) as two processes in digital libraries are related to technical environment and human/system interaction. Societies (actors) as a factor in dimensions of some ‘S’ concepts in digital libraries, including accessibility and pertinence of the digital object and also availability, effectiveness, extensibility, reusability and reliability of services, is appreciable with digiqual model. Scenario as a factor in dimensions of ‘S’ concepts in digital libraries including pertinence, and conservation of the digital object; availability, effectiveness, extensibility, reusability and reliability of services, is appreciable with digiqual model. Streams and structures as factors in dimensions of some ‘S’ concepts in digital libraries including accessibility, conservation, relevance, similarity, significance and timeliness of the digital objects; accuracy, completeness and conformance of metadata specification; completeness as a collection; completeness and consistency of the catalog; completeness and consistency in the repository; efficiency and effectiveness of services, is appreciable with digiqual model. Space as a factor doesn’t exist in any of the ‘S’ concept dimensions in digital libraries and it is not appreciable with digiqual model. Finally, the development of ‘S’ concepts in digiqual dimensions in order to integrate the quality of services is proposed.

The study’s purpose is to explain Guilford’s intelligence model as a management information system processor with library and museum’s entities in the content, processing operations, and products levels. The research method is exploratory and content analysis. The findings show that in the content level, auditory is equivalent with audio content objects, visual is equivalent with visual content objects, semantic meaning is equivalent with the specialized knowledge’s audio and visual content objects, symbol is equivalent with ISSN and ISBN, and Fankha identifiers, behavioral is equivalent with responses based on the knowledge of users. At the level of processing operations, recognition is equivalent with the process of recognizing content objects, memory is equivalent with the process of storage and retrieval, divergent thinking is equivalent with the process of creating value added information and knowledge, intellectualism is equivalent with the process of categorizing objective and subjective information, explicit and implicit knowledge’s content objects, evaluation is equivalent with the process of evaluating performance. At the level of the product, the unit is equivalent with the elements of content objects, the relationship between the units is equivalent to the relation of the elements of content objects, the class of the group is equivalent to the classification of content objects, the system of identification of structural relationships is equivalent to creating the semantic content of content objects, the transformation of the processing is equivalent to extraction, discovery, and argumentation of available data, the application derived from the use of content is equivalent with databases, expert systems, and mapping of knowledge. As a result, the information management system for library and museum performance entities is possible based on the structure of Gilford’s conceptual framework of intelligence

The Aim of current research is to study the feasibility for initiating the electronic reference services in public libraries of Guilan province which are under the authority of Iran Public Libraries Foundation. This study is applied, descriptive and survey-based. Data was collected using two questionnaires based on the Orbis questionnaire and the American Library Association's evaluation tool, one of which was used for the heads of the libraries and the other for the librarians and library authorities. The research population consisted of 65 active libraries established in Guilan Province. Data analysis was done descriptively by Microsoft Excel and SPSS. The results showed that more than two third of the surveyed librarians have the necessary skills for this job and it is possible in this area. The majority of the surveyed libraries have no problems for initiating the electronic reference service with regards to the technical equipment based on the selected software used in the study, but there is a shortage in electronic databases and resources to satisfy the information needs of users. Currently, there is no special budget dedicated for the establishment and provision of such services and it is the main problem of the libraries for providing electronic services. It can be concluded that the public libraries of Guilan province are able to launch virtual reference services by providing the necessary electronic resources and databases.

AbstractThe purpose of this study is a survey of the relationship between cognitive and metacognitive strategies and information seeking behavior among the faculty members in Agricultural Research, Education and Extension Organization (AREEO). The method of this study is descriptive survey – relationship and data are collected by 2 questionnaires; one is learning and studying strategies questionnaire and the other is information seeking behavior questionnaires. The research community consists of all faculty members in Agricultural Research, Education and Extension Organization (N= 2012) and the sample of this study size is determined by Morgan table (N=322) and probability stratified sampling is used as a sampling method. Descriptive and analytical statistical methods are used to study the questions. The results indicate that the correlation coefficient between cognitive strategies with information seeking behavior among the faculty members is r=0/065, and according to p=0/24, that means, there is not a significant relationship. The correlation coefficient between metacognitive strategies with information seeking behavior among the faculty members is r=0/128 and accordingly the value is p=0/02, that means there is statistically significant relationship. Finally, this study indicates that increasing metacognitive strategies among the faculty members can increase their information seeking behavior.

Pur: the purpose of the present study is to determine the level of knowledge sharing and creativity and the relationship between them. Among Libraries’ Librarians Tarbiat Modares University in 1392. Methodology: the methodology applied for the present study is descriptive-correlation. The study population included 50 librarians and libraries of Humanities, Engineering and the Central Library of the Tarbiat Modares University. Findings: the status of knowledge sharing among the librarians of Tarbiat Moddares University is far from satisfactory, but the creativity of these librarians is up to the scratch. The rate of solidarity between knowledge sharing and creativity with %8 shows that no significant solidarity or relationship exists between them .Conclusion: the libraries ought to participate in educational and research activities in order to improve and enhance knowledge sharing, to propagate and share information and knowledge among librarians and ought to provide required infrastructures for sharing knowledge in the library.
