This paper aims to discover the conceptual system of Persian Subject Headings (PSH) through the content analysis method. In order to discover the PSH's global hierarchical structure (GHS), all PSH records (84545 records) were investigated. Conceptual system of PSH was compared to the both Academic system of Iran and Library of Congress Classification system (LCC). Findings show strong relationships between PSH and LCC in Science (%19.5), Technology (%14.4), Social Sciences (%10.6) Medicine (%9.5) and Philosophy and Psychology (%6.6) classes. Identifying the hierarchical structures (tree structures) embedded in the entire PSH, 241 trees were found. Large trees and top headings (e.g. Medicine and Psychology, Sociology, Philosophy, Contracts, Founding, Mathematics, Management, law and …) were selected as the representation of the conceptual system of PSH to compare with the two other conceptual systems in this study. It shows that only %21.05 of top headings match the academic system of Iran and it is narrower than it. It means that a limited part of the academic system has been represented in PSH. The matching rate of top headings with the LCC is %71.05. In conclusion, the conceptual system of PSH is narrower than it is expected. It is recommended to correct the errors and enrich both its relational structure and conceptual system.

Cloud Computing is dominant mode of current and future of information and communication technologies. It is not beyond the realm of possibility that it would foment upheaval within libraries and information centers service-wise. The wide-reaching extent of these changes would envisage a new feature to libraries both in organization and service delivery. The present study, employing a descriptive analysis method, examines the concepts of cloud computing while laying the foundations for a cloud-based library as its corollary. While presented as a conceptual construct, the paper posits that the model can solve some of the issues such as digital right managements as well as copyright. Several models are offered and discussed with respect to applicability, missions, client group, financing as well as service blendals.

To study the scholarly production of Iran in the basic sciences and identify the place of the country among Islamic countries and the world، and also comparing the different disciplines in this field of knowledge، help to plan properly to provide necessary facilities for the advancement in these areas. The purpose of this study is the analysis of scientific poverty line of Iranian scientists and comparing them to the scientists of the superior Islamic countries. This is an applied research. Data were gathered and analyzed with the descriptive approach. In this study data collected from ISI during 1990 to 2011. Five disciplines of basic sciences، including mathematics، physics، chemistry، biology and earth science were studied. Yi and Xi and Sx scientometrics indicators were used. Based on the findings of this research، Iran with 35542 documents، academic ability 0. 509 % and the relative performance of 0. 468% is in the first place among the Islamic countries. Iran also is in the first place in physics، chemistry، earth science and mathematics and in second place in biology among the Islamic countries. Despite Iran''s ranking first among Muslim countries، it is below the scientific poverty line in terms of Xi and Sx indicators. So it seems necessary to pay more attention to production and distribution of basic science especially in biology. The weaknesses and barriers also should be recognized.

C. 27002 in the field of information security management in the central libraries، is 4 being in a good condition and there is no significant differences between the performance of the Central libraries of the governmental Universities in Tehran، since It is not observed significant difference between them in the field of information security management according to ISO IEC. 27002.

This research addresses the issues of measuring the geographic distribution of scientific wealth in Iranian provinces. It focuses on mapping and visualization of scientific production and use in the country. The share of each province in the national scientific wealth of Iran has been measured through counting the documents indexed and retrieved from IRANDOC bibliographic databases. The seven specialized databases of IRANDOC include journal articles، conference articles، theses، governmental reports and so on consisting over half a million bibliographic records. Dividing the provinces in three classes of poor، average and rich according to their contribution in Iranian scientific wealth، Tehran and Isfahan provinces were tagged as the richest. A comprehensive description on developing a GIS model to visualize the distribution of scientific wealth in Iran is given in the paper and results are interpreted. In each case، the search results have analyzed more via a post-query spatial analysis for extraction of locations and comparing the extracted locations with a national gazetteer in order to find the proper province (s) for each single retrieved record. Using an interactive map، the share of each province in the retrieved results was illustrated on map and compared with the other provinces. It has been noticed that a combination of online or offline interactive maps e. g. Google Maps and Google Earth and geographically tagged bibliographic data can result in a location-aware search and retrieval tool where in-depth analysis of search results will be possible. The outcomes of this research can be used in planning for sustainable and balanced development of the country.

Knowledge sharing (KS) is a process through which individuals mutually exchange their knowledge with each other and potentially through this process، opportunity for learning new experiences، training and implementing experience، skills and abilities are provided. Therefore، KS is important for various organizations. Accordingly، and because of the importance of KS، this research studies the status of KS and management of public universities’ central libraries websites in Tehran city. Survey method is pilot-descriptive and research tool is a questionnaire. Research community is staffs and stakeholders who are working or commenting on websites. Results of research show that sharing knowledge and influencing factors (including individual factors، organizational and information technology) in the study population have a more favorable situation. Findings indicate that among the above three factors، organizational factors than other factors are more barriers on KS. Website management does not have good situation and website management by libraries and good condition، by a library is limited to content part and other parts of technical and structural are managed by the University’s IT Section. Employee’s capabilities and skills that could be effective on working with the website and KS do not have good situation، especially in website’s structural and technical parts and staffs have more skill for working with the content of website. In all، although KS has a good situation among staffs، but KS and management of website is not coherent، dynamic and efficient.

The main objective of this research was to evaluate creativity components in the central library websites of the universities dominated by the Ministry of Science، Research، and Technology (MSRT) of Iran to improve those components in university libraries. Research population included 35 library websites of the mentioned universities which had a separate homepage for their central libraries. Data were gathered by the use of a checklist that was made by researcher based on literature. This checklist contained the dimensions of creativity in university libraries websites. It encompassed 30 creativity components which were categorized under 4 main dimensions: originality (novelty، uniqueness)، form (design and aesthetics)، function (interest، usefulness، usability، and personalization)، and source (motivation، and creative skills). To test the content validity of the checklist، it was sent to 9 specialists to gather their views. The results indicated that 3 library websites (Zanjan University، University of Mazandaran، and Tehran University)، were gained top ranks. In the other hand، the central library websites of 3 others (Babol Noushirvani University of Technology، Tarbiat Moallem Azarbayejan University، and Birjand University) were at the end of ranking scale of creativity. Only 9 out of 35 investigated websites (including Zanjan University، University of Mazandaran، Tehran University، Imam Khomeini International University، Ferdowsi University of Mashhad، Isfahan University of Technology، University of Sistan & Baluchestan، University of Tabriz and Arak university) were in desired conditions of creativity components. Findings showed that، out of 4 creativity dimensions (originality، form، function، and source) evaluated، 65. 71% of components of source dimension (the most) and 40% of function dimension one (the least) were available in the 35 central library websites of investigated universities. The results also revealed that there was a significant correlation between the ranking of the central library websites of MSRT and the ranking of the same universities websites regarding the receiving links (at α=0. 05).

The aim of the study is investigate the Federated search engine user interface criteria from perspective of Al-Zahra post graduate students. In this research، survey analysis has been used. The study populations were all post graduate students of Al-Zahra University. Because of the extensive community، stratified random and relative sampling was used and total 330 students were accepted as Sample that only 303 people participated in this study. For data collection a researcher made questionnaire designed. The criteria from literature study. The results of the questionnaire by using SPSS software (version 20) and Excel 2007 application were analyzed. The results showed that the major component from graduate students'' perspective is guidance and navigation and searched filter components. Results indicate that more than 50 percent of students the importance of 74 criteria of 96 criteria considered high and very high and، (therefore) the majority of the criteria in the study from the viewpoints are acceptable. However، findings also showed that among the four components of this study، the search filter، display and record review، consolidation and guidance is a positive relation، and between the views of different faculties is not significant difference about the importance of criterias and components.

The main objective of this research is to rank the critical success factors of knowledge management using fuzzy quality function deployment (QFD) approach in MECO Company. The research has utilized a three-step qualitative-quantitative-qualitative strategy. At the first step (1st qualitative phase)، the critical success factors of knowledge management and knowledge management outcomes were characterized in MECO. Then، the critical success factors of knowledge management which were identified by the first step were ranked using fuzzy quality function deployment in the second step (quantitative phase). Afterwards، some solutions were provided to realize and improve the critical success factors of knowledge management in the selected company within the third step of research (2nd qualitative phase). 11 critical success factors of knowledge management were introduced in addition to 4 knowledge management outcomes by the first qualitative phase. The result from the quantitative phase were indicative of the fact that “human resource management”، “support and leadership of management”، “organizational infrastructure”، “organizational culture” and “activities and processes” are known as five critical success factors of knowledge management in the chosen company. Furthermore، 23 solutions provided by this research in order to realize and improve the critical success factors of knowledge management in this company are achieved as a result of implementing the second qualitative phase. Based on the information accessible for the researchers، this is one of the first works which evaluates the key factors of successful knowledge management through fuzzy quality function deployment approach. It is expected that the proposed method would represent appropriate tools for enterprises which have decided to implement knowledge management because it prioritizes the critical success factors based on the knowledge management outcomes.

Abstract: Information and communication technology has had effects on the different aspects of living، like working ways. One of these effects is to work anywhere، far away office and without geographical limitation. This working method has advantages and disadvantages that can affect on its performance and contituity in organizations and offices. This article reviewed shortly the literature of teleworking and the advantages and disadvantages of teleworking، then surveyed the viewpoint of teleworkers in department of information processing in National Libray and Archives of I. R. of Iran. The results showed that teleworking had benefits and porblems in this department and despite of that fact (especially weakness in techonogical infrastructs)، all of teleworkers in research population (100%) tended continue teleworking. Teleworkers had a high satisfaction of teleworking (5/53).

Many companies have adopted Service-Oriented Architecture (SOA) as an approach to improve agility and increase performance of system development. However، deploying SOA has been encountered to some challenges and problems including difficulties in designing effective decision structures and building a SOA roadmap، lack of service funding and lack of consistent governance processes. Therefore، to address SOA challenges، organizations require a comprehensive and applicable SOA governance framework to implement management and control mechanisms. Study of existing SOA governance frameworks reveals that these frameworks are not expressive enough to cover all important elements of SOA governance and also، the y have very little discussions and clarifications regarding underpinning structures such as SOA processes and activities، governance procedures and measurement metrics. In this paper، in the process of proposing a new SOA governance framework، a set of important elements for a desired SOA governance framework is proposed. Based on these elements، a more comprehensive and expressive framework is developed based on governance structure of COBIT. It focuses on covering SOA governance elements and resolving the shortcomings of the existing frameworks and can delivers an appropriate solution to help enable effective SOA governance.
