This survey is aimed to know research methods of master's dissertations in the field of the Knowledge and Information Science in Tehran state Universities from 2006 to 2012 and also to specify the abundance methods of research at state universities of Tehran. This survey has done by content analyzing and bibliometric method. The society of research is 154 dissertations in MA degree at University of Tehran, Tarbiat Modaress and Medical University of Iran. The tool of information gathering has been a check list. Results show that among 154 studied dissertations, Tehran University has the most one. The most abundance in methods of survey is "survey method" (70 %) and the least abundance is "documenting method". After reviewing the thesis of knowledge and information science the State University of Tehran was determined that the increased interest in using survey method and the documentation method Has been used less.

Current study has been done to assess the ability to understand the Vocabularies used in the user interface of Web of knowledge and Scopus databases by Shahid Beheshti’s graduate students. The methodology of present research is quantitative. A survey has been done as a research method. The research population was graduate students studying in Shahid Beheshti University and the random sampling method is used. The data were collected by questionnaire from 350 graduate students who 309 (88%) of them responded to the questionnaire. The results showed that Vocabularies used in interfaces of both databases had good capabilities of understanding. 69.4% of Vocabularies studied in Web of knowledge have very high and high level of understanding and 30.6% of words had the modest capabilities of understanding. According to results of words studied in Scopus, 59.5% of Vocabularies had very high and high capabilities of understanding. However 24.3% of the words have the modest and the 16.2% of the Vocabularies had low and very low capabilities of understanding. In this study, it was found that the plural words have higher level of understanding than singular words; also the level of understanding of short sentences is higher than long sentences; the understanding level of imperatives sentences is higher than declarative sentences and adjectival phrases and explanation of the words effect on the understanding of words concept. The results of the research showed that familiarity with and use of the database and the knowledge of English language effect on the better understanding of words. Finally, by using the obtained results and to enhance of theVocabularies understanding capabilities the suggestions is presented.

The purpose of this research is analysis of pluralistic methodology and tools in research papers of FaslnameKetabe Iran from 1385 _ 1389. and discussion communication of them to gather and with articles ‘ author. This article is performed by using content analysis method and. The population was 161 of articles in FaslnameKetabe. Among161 research papers only 59 cases (36.46%) have benefited of pluralistic methodology and 12 cases (7.4%) of pluralistic tool.So can be said that in this papers pluralistic method and tool have been used very little. According to the results of Kay square test there is a significant relationship between pluralistic method and tool. While, there isn’t significant relationship between authors’ grade in charge of science and education and selection of used methods and tools in research.

The purpose of the present research is to study the feasibility of implementing distance reference services in the central libraries of Islamic Azad University (Region 13).
This is an applied research that has been done using survey approach. The research population included post graduate students¡ librarians and managers of central libraries of Islamic Azad University (Region 13). 380 Students were selected using stratified random sampling based on Cochran formula. As the number of librarians and managers wasn’t very much¡ all of them have been considered in study. 3 researcher made questionnaires were used to gather data. Their validity and reliability were confirmed by Library and Information Sciences specialists and Cronbach’s alpha.
Findings: The findings showed that the mean level of familiarity with distance reference service technologies and its usage were higher than average among students. More than half of them preferred non-attendance reference services. Also¡ librarians’ and managers’ familiarity and usage were in a desired level. Libraries had not enough facilities and equipment and budget to set up distance reference services.
According to research findings¡ despite the human resources are appropriate¡ due to the lack of facilities and equipment¡ as well as funds¡ setting up distance reference services in mentioned libraries is not possible at present.

Descriptive statistics consist frequency, percentage and mean, while for analytic statistics Single-Sample T test and Pearson correlation coefficient were applied. The finding showed technological factors (relative advantage, adoption, easy to use, Trainability and observability) were affective in Namaye Nashryat technology adoption by librarian in public library in Tehran. There was a significant positive and direct relation with adoption. Moreover, the adoption and complexity are recognized respectively as the strongest and the weakest affective factor in technology adoption. Results showed that all technological factors have been affecting the adoption of these technologies.

The highest number of citations has been received from Chinese, Indian, American, Spanish and Turkish researchers. The results also demonstrated that among Iranian universities and research centers, Islamic Azad University was the most productive university and Razi University of Kermanshah had the most citation impact. Moreover, among all sub-disciplines of the Chemistry, Multidisciplinary Chemistry has had the highest share in scientific publication with 6462 documents. Conversely, the least number of publications has been published in Applied Chemistry with 1533 documents. The results of the study also revealed that researchers from 81 countries all over the world had scientific collaboration with Iranian researchers.
