Abstract
Background and Aim: Using Hirsch index as an important tool to describe the scientific outputs of researchers has caused some authors to increase their self-imposed parameters, increase, citing themselves. Therefore it is necessary to consider the effect of self-citation on Hirsch index for every author to have better measuring on the quality of researchers scientific production.
Materials and Methods: This research is descriptive method of citation analysis in general and specifically self-citation analysis. The study, are Iranian prolific authors in the field of medicine that have at least 30 documents indexed in Web of Science database between 2004 to 2006. Citations following up was studied till December 2010 Results was analysis using Excel software version 2007.
Results: The average self-citation observed between prolific authors in medical field was 25/89 percent. Hirsch index for 30/77 percent of authors had changed considerably. The authors rating scheme based on Hirsch index was done after removing self - citation so that 38/46 percent of authors decreased to lower level.
Conclusion: Considering that 10 to 30 percent of self-citation can be normal and justified, the status of self-citatin of Iranian prolific authors in medical field is desirable. Also, lower rates of self - citation of these authors doesnot affect Hirsch index.

Abstract
Background
and Aim: The lack of paying attention
to overlap between two databases cause purchase of duplicate resources waste of
funds. This study examined overlap of articles in the field of cardiovascular
which was indexed in Scopus and Web of science databases during years 2001 to
2010.
Materials
and Methods: In this study, at first,
sub-headings in cardiovascular field from medical thesaurus (Mesh 2012) was
extracted, then each keyword in the title of the articles in both databases
were searched and articles retrieved. Then bibliographic information of these
articles entered into Endnote X3 software and afterwards was arranged based on
alphabetically title. As a result common articles between the two databases and
unique articles to each database was determined. Using SPSS version 0.1.0.8 the amount of relative and traditional overlaps was
calculated between the two databases.
Results:
Totally 45,680 articles were
retrieved. There were 27,979 common titles, 14,875 articles belonged only to
Scopus and 2826 articles belonged to Web of Science. Finally traditional
overlap was 61/5%. Overlaps of Web of Science with Scopus 65/28% and Scopus
with Web of Science were 65/28% and 90/82% repectively.
Conclusion: The amount of relative overlap between the two
databases as well as relative overlaps from Scopus with Web of Science is more
than the relative overlaps from Web of science with Scopus. It means many
articles that have been indexed in Scopus don’t exist in the Web of science.

approach. The population of the study includes scientific journals and articles in
medical sciences indexed in Scopus database. In this study, EMRO academic
products and 140 scientific journals have been investigated.
Results: The results show that a large number of member countries’ scientific
works have been produced and published in medical fields (The main topic of
144,628 out of 573,067 documents published by these countries has been medical
fields). Meanwhile, the number of journals which were indexed during the studied
period increased from 17 to 127.
Conclusion: The production of scientific documents and academic journals in
the field of medicine in EMRO member countries has increased during the studied

Abstract
Background and Aim: Indexing a country's scientific journals in international citation databases can lead to the promotion of its academic status and its participation in global knowledge production. This study aimed to assess the conformity of Iranian English-language medical journals’ citations with the objective criteria of journals in the selected databases.
Materials and Methods: This was a descriptive, evaluative research. The study population included 52 Iranian English-language medical journals that are not indexed in Web of Science, PubMed and Scopus databases and 465 articles in these issues, and about 11235 citations to the articles. The data have been collected by a checklist. For data analysis, Excel software was used.
Results: Some 88.5 percent of journals had a style for writing references; a style that has been observed by most of them. The rate of self-citation was low. Only 2.9 percent of citations were done in the year this study was performed. Journals with 87.2 percent had received the highest number of citations. The old citation time and the imbalance in the types of cited resources were the most important reasons of the weakness of the studied journals and of their not being indexed in the mentioned databases.
Conclusion: Providing valid styles for writing references and controlling the citations accurately should be put on the agenda of journals. The time of references must be newer, and there should be a relative balance in the types of referenced sources.

Abstract
Background and Aim: Periodic assessment of medical sciences databases is a necessary principle of the process of enhancement these databases. The aim of this study was to Comparatively evaluate structural features of medical bibliographic databases including MedLib, Barakat knowledge network system, Irandoc, SID, Magiran and PubMed, based on Gulliver criteria.
Materials and Methods: This survey was carried out in accordance with Gulliver's assessment checklist 2002. This checklist consists of 12 sections including entry page, searching, limiting, record viewing and manipulating, graphics, record retrieval, selective dissemination of information services, general design, terminology, icon design and placement, help and advanced features. The study was conducted on five national databases and one foreign database.
Results: Among the databases, PubMed gained the first ranking with a score of 89.16 percent. Among the national databases, new SID database with a score of 57.5 percent gained the top rank. Other databases including Irandoc (56.25%), Magiran (54.58 %), Barkat knowledge network system (52.91 %), MedLib (51.25%) and old SID (47.5 %) obtained next ranking respectively.
Conclusion: Despite improvements indices in updated national databases, many of the indicators are far from prestigious databases such as PubMed. It is recommended that in development of national databases, features such as search, help, SDI, entry page, advanced features and record retrieval should be considered.

Abstract
Background and Aim: Scientific journals are known as one of the basic tools in knowledge development in today's world and have a special place in publication of the newest achievements of human knowledge and science. This study aimed to evaluate Iranian journals of medical sciences in Scopus database and determine their level in the world.
Materials and Methods: This is an analytical-descriptive study with Scientometrics approach. The research population includes all Iranian journals in the field of medicine which are indexed in Scopus database until 2016. We used SPSS and Excel software to analyze data and NodeXL to draw shapes and pictures.
Results: The findings show that the number of Iranian journals increased from 2 in 1999 to 78 in 2015. Also, 15 cities and 29 centers and universities have played a role in publishing those journals. Meanwhile, the findings show that Iranian indexed journals are at a lower level compared with those of the developed and industrial countries.
Conclusion: The most important reasons for Iranian journals' growth were "the policy of Scopus to increase scientific journals", "observance of standards and compliance with international fashion and standards of medical journals”, and the like. We concluded that Iranian journals compared with those of other countries are not at a good quality position and that it is essential to have an appropriate policy by the Ministry of Health and its subordinate Universities.

Abstract
Background and Aim: With the development of the Internet and databases and the increasing need to institutionalize evidence-based medicine, physicians' awareness and use of evidence-based medical databases and concepts are considered to be necessary. Therefore, the aim of this study is to evaluate the knowledge and use of evidence-based medical concepts and databases among residents of Shahid Beheshti University of Medical Sciences (SBMU).
Materials and Methods: The present study is an applied and descriptive research. The population of this study comprised 192 SBMU residents in 2016. A questionnaire was used for data collection and SPSS software was applied for data analysis.
Results: The findings showed that residents obtained 2.99 for knowledge and 2.73 for the use of evidence-based medical databases out of a total average of 5 points, which indicates that their knowledge and practical use of evidence-based medical databases are moderate. Databases about which residents have the highest knowledge and practical use are UpToDate, PubMed Clinical Queries, and
Cochrane, respectively.
Conclusion: The majority of residents at Shahid Beheshti University of Medical Sciences do not have sufficient awareness about databases and concepts of evidence-based medicine; in fact, most of the resources that are used to answer their information needs are non-evidence-based resources. Therefore, planning to accept evidence-based medicine and databases and teach them to residents is essential.

Abstract
Background and Aim: To understand veterans’ needs and to make future generations familiar with the culture of self-sacrifice and martyrdom, we need a database to store information. The first step for designing a base is to provide a conceptual framework of the base. This study aims to provide a conceptual model to create the national base of veterans in Iran.
Materials and Methods: This research was conducted in a two-step, mixed approach. The first step was conducted using content analysis method (quantitative) and the second step using Delphi (qualitative) technique. Data collection tool was Excel 2016 software. With the help of Delphi technique, a researcher-made conceptual pattern was sent to the experts in three rounds. Based on their views, the final plan of national base of veterans was formed.
Results: Among the main components, introduction to the war was removed, history of war changed to history of wars, link to links, other materials to other contents, art and war to war and art, and the sub-component of possibilities turned into the main component. Veterans’ personal information turned into veterans’ database that changed into subsidiary components of the martyrs / veterans / prisoners-of-war / warriors database.
Conclusion: The main components of the conceptual pattern of national base of veterans of Iran include: home page, introduction, conflicts and operations, equipment, war zones, facilities, news, cemeteries of martyrs, veterans’ rules, questions and answers, history of wars, war and art, veterans’ database, archives, links, guide, contact with us, FAQs, other content, resources, about the base, search, map.

Abstract
Background and aim: A Library is a safe place to research and study for some students, but it creates anxiety for others. The main purpose of this research is to investigate the library anxiety among Kermanshah University of Medical Sciences(KUMS) residents in using information sources and electronic services based on five factors of Bostick scale.
Materials and Methods: The study was a cross-sectional survey. The sample size was 197 persons who were selected using simple random sampling. Data collection tool was a researcher-made questionnaire whose validity was confirmed by experts and its reliability was confirmed by Cronbach's alpha coefficient of 0.809. The questionnaire consisted of 41 questions on a five-point Likert scale. The library anxiety questions were designed and localized based on the five factors of the Bostick scale. Data were analyzed using descriptive statistics, mean, standard deviation and analytical statistics by Kolmogorov-Smirnov test and Pearson correlation coefficient using SPSS 23 software.
Results: The mean score of library anxiety was 78.32, the mean score of familiarity and usage was 32.08 and 29.54. Mechanical and emotional factors had the highest mean of library anxiety factors. Mean library anxiety was not significantly different between male and female residents(p>0.05). There was a significant relationship between residents' library anxiety and their skills in using information resources and e-services.
Conclusion: The results indicate a level of library anxiety among the assistants. Accepting this fact can be a positive step in solving the problems associated with the use of information and electronic resources.

Abstract
Background and Aim: In this study, in order to increase the visibility of articles in Scopus journals of Tehran University of Medical Sciences (TUMS), selective dissemination of information (SDI) service was presented and its impact on some citation indices was investigated.
Materials and Methods: This is a semi-experimental study of two groups (pretest-posttest design with a control group). In this study, TUMS Scopus indexed journals (20 titles) were randomly divided into test and control groups and their citation indices were assessed. Then, the SDI services for test group journals were designed based on PubMed's Alert system and presented to the university's top researchers for one year. Finally, the citation indices of the journals of test and control groups were reassessed and compared. For data analysis, independent t-test, paired t-test and, covariance analysis were used.
Results: Comparison of mean citations as well as SJR, SNIP and CiteScore indices before and after the intervention showed no significant difference between the test and control groups. But the average CiteScore in both groups after the intervention was significantly higher than the average before the intervention.
Conclusion: The results showed that the provision of the aformentioned services in the time period defined in this study had no significant effect on the citation indices. However, the valuable experiences gained in this study will undoubtedly be applicable to future research as well as services to researchers, librarians, and journal managers.
