This paper describes the approaches and the factors which are important in the designing of database interface. The models and approaches and also the designing principles are discussed. Regarding this the paper talks about the cognitive elements and the behaviors which influence the human computer interaction when searching a database. It concludes with some guidelines and suggestions for interface designers of information systems.

This research is a comparative evaluation of PJCR and SID from the viewpoint of journal selection criteria. At first, for accomplishing this study, some criteria which are needed for evaluating PJCR and SID were extracted from the texts and ISI database, then they were used after testing their validity. Some information is gained from the observation and the other are gathered from a checklist which includes 4 general criteria and 22 sub-criteria. In some cases, necessary information was completed via interview with some experts and managers in their databases. Also, for some criteria, separate questionnaires are designed, and other information is extracted from some journals that are indexed in their databases and other information is gained from the users and article's authors.This study was carried out using different methods, the library method and in some cases the survey method and for analyzing and comparative the results. We also used the evaluation technique. The results show that PJCR is more in concordance with journal selection criteria than the SID

With the development of IT in organizations‚ using of it is increasing in KM too. Using LAN‚ Intranet‚ email and databases have an effective role in KM. What in IT is important is the information base thought or thought that is composed of a collection of productive and reliable information. It has the most contribution in km in a way that it is hidden behind all KM activities but it is not the only element of KM. Other elements such as the changing organization structure and process of decision making as well are important in KM components.Most analysis show that the emergence of technologies facilitates the distribution and performance of KM but there is this view that these technologies sometimes are anti-knowledge and anti-KM and only store information not knowledge.The aim of this article is to show the role of modern technological tools for improving KM‚ for example Intranet‚ databases of organization and the use of IT in the improvement of KM in Iran and in other countries. The paper also describes the advantages and probable disadvantages of these tools in KM.

While, there have been many efforts in research & practice about digital libraries, library managers encounter whit new challenges for developing digital libraries. These challenges include "domain attitude", "building digital collection", "staff" & "preservation". This paper discusses the issues & challenges of digital libraries from the viewpoint of management using other libraries' experiences and research results and give solutions to these challenges. The challenges may be grouped under the following five broad categories: attitude, staff, building digital collection, digitizing tools and preservation.

This research was conducted to evaluate the structure and content of electronic databases of Iranian journals. The population included Sid, Magiran and Namamatn databases. To review the structure of the target databases, data were gathered by a checklist and to review the content of them, the database managers were interviewed and some aspects of the databases were observed. The compatibility rate of Sid, Magiran, and Namamatn with the structure criteria were 50.43%, 54.70%, 41.88%. respectively. Findings showed that the coverage of Magiran, in comparison with all the Iranian journals, and the Sid, in comparison with scientific and research journals, were more comprehensive (36.35%, and 94% respectively). The databases subject coverage was reviewed and it was revealed that Sid database was rich in medical and paramedical subjects but Magiran and Namamatn databases included more journals in human sciences. Contrary to Sid and Magiran, and because of using a controlled indexing language, Namamatn database had a more clear and consistent procedure for indexing. The traditional overlap of the databases was calculated. The most overlap was observed between Magiran and Sid databases (with 23.82%) and the least one was between Sid and Namamatn databases (with 0.67%). Overall overlap of the three databases was calculated 5.12%. Relative overlap was also measured and findings showed that the most overlap was in Sid (45.15%), and the least one was in Magiran (10.47%).

National Information Policy is a framework for information organization and access for the Society. One of the most important function of such a framework is to provide a balance among competitors interested in the information cycle. To formulate such framework, we should understand the national information policy. The aim of the present paper is to address the concept, significance, scope and constraints of the national information policy.First, the definitions and the common elements of them one discussed. Then the national information policy map introduced by Rowland is analyzed with reference to different perspectives and types of information. Also the different levels and the advantages of addressing such a concepts for Iran are discussed.

The aim of this research is to discover the relation between citations of documents and subject related dissertations in library and information science. In this study citations are used as content descriptors of documents. A comparison has been made between subject related and citation related documents to explore the degree of capability of citations to bring together subject related documents. A measure of relatedness was computed between each pair of dissertations based on number of overlapping citations. For this aim, we used library and information science dissertation abstracts subject categorization as a base for categorization of studied dissertations. Degree of subject similarity was measured by title keywords and degree of citation similarity was measured by overlapping citations among them. It is shown that the dissertations which have more overlapping citations, have less subject similarity. Therefore, there is a weak correlation between the two types of subject grouping and citation grouping of documents.

Using a comparative survey method, this study has explored the problems which Persian articles databases in searching different morphologies of a word are encountered with. The population of the research covers three Persian articles databases including the Regional Information Center for Science and Technology, the Scientific Information Database, and the Iranian Information and Documentation Center. A checklist of 17 keywords were carefully chosen from the Persian texts which represent a challenge of persian language facing the new technology. Then the keywords were searched in the mentioned databases and the results recorded. The study indicated that the recognized morphological challenges in the Persian language had a high impact on information retrieval in each database and no databases have considered words morphological problems in a comprehensive and considerable way, just each one has tried to solve a small number of mentioned challenges separately.

Mobile phones have revolutionized telecommunications and communications and have had a massive impact on our private and social life. Mobile phones have had an undeniable impact on all aspects of our social, economic, cultural and scientific lives in a way that it would not be wise to ignore them in designing and implementing any information system. This article aims to introduce and discuss the capacities of mobile phone technology as a communication tool for library services, with an emphasis on its application in Iranian library and information centers.

The main purpose of this study was to investigate the role of information resources and psychological characteristics on the information seeking behavior among Iranian agricultural extension and education students. This research was a survey and the statistical society of the study consisted of all B.Sc and M.Sc students of agricultural extension and education from 4 universities in Tehran, Shiraz, Ramin-Mollasani and Kermanshah. By using stratified proportional random sampling, 290 students (230 B.Sc & 60 M.Sc students) were selected by Morgan table. Statistical methods of C.V, F& t-test, Tukey test, Scale free technique, principal components analysis technique and Pierson correlation were used for data analysis. The findings revealed that although faculty members are first priority for taking information by students, but at both educational levels of B.Sc & M.Sc, the major human information resource related to the student educational activities had been senior students. Psychological capability of conscientiousness was at a high level in female students and among of B.Sc students, but psychological capability of Extraversion was high in male students and among of M.Sc.

Agility as the irrecusably and dominant paradigm of business in the third millennium is just the option that organizations should accept for their survival. Consequently, there have been lots of research in obtaining a proper level of agility in organizations. But lack of attention to basic elements of competition has made many of these effort inefficient. Quality as the most important customer need forms an integral part of competition by the end of the last century. In this research with considering these two significant concepts, agility path was defined through quality coverage. The agility -as the dependent variable- was described through multi-level regression. The agility describer elements were determined and finally ranked by multi criteria decision making techniques. Results showed that setting clear and quantitative goals by the manager and committing to them, updating library employers' information and proper delegating of authority are the most effective quality components which affect library agility.
