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: Citation is one of the journals ranking factors. Self-Citation rates regarding journals `performance, especially in international databases, is important. The aim of this study is to examine the effect of Journal self-Citation on Impact Factor of Iranian English medical journals indexed in the Web of Science and Islamic World Science Citation Center.
Materials and Methods: The Impact Factor of 12 journals in WoS and 26 in ISC were studied during years 2006-2009 using citation analysis and Journal self-Citation. Self-Citation rate were calculated using cited journals and citing journals tables in ISC. Wilcoxon test and Mann-whiteny test were used for comparison of self-citation rate between two databases. In order to determine any correlation between journal self-citation and IF in WoS, Pearson test was used. In ISC, Spearman test was performed. For comparison of two correlations test, Covariance test was used.
Results: No significant difference between Journal self-citation rates in two databases was noted(p>0.05).There was a significant correlation between Journal self-citation and Impact Factor in WoS(p=0.007, r=0.64). The correlation was not statistically significant in ISC(p>0.05, rsp =0.23). There was not any significant difference between the relations of Journal self-citation and impact factor in two databases(p=0.526).
Conclusion: Attention to the Journal self-citation rates for comparison of Journal Impact Factor in WoS is more important than attention to the comparison of these journals between two Databases.

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.

Abstract
Background and Aim: Today journals are one of the main platforms to exchange information between researchers. This study aimed to assess the status of Approved Latin indexing journals in the field of medical science citation indexes Web of Science and Scopus databases.
Materials and Methods: This study was a cross-sectional descriptive survey. Statistical population of the study was 83 titles Latin journals approved by the Ministry of Health that examined indexing situation of them in Web of science and Scopus databases between the years 2005-2010. Data collection tool was a controlled checklist that was established by consult with experts and specialists in related areas and its reliability was estimated 90 percent. Data were analyzed using the software spss16.
Results: Survey the status of journals showed that slightly less than 26 percent of titles indexed in Web of Science. Also in Scopus Citation Index 69 percent of journals was indexed. Compare criteria for indexing journals in Web of Science and Scopus database show that bibliography information of not indexed journals considered and in some journals (29/30 percent) number of international standards were not mentioned. Also, some journals contact information (postcode publication 9 percent) was not included.
Conclusion: In general, it was observed that despite the enormous growth of scientific journals between examined years, terms of adaption with the criteria of indexing are in unfavorable condition and managers of Latin scientific journals should try to improve their quality and quantity.

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: In the field of scientometrics, little attention has been paid to stem cells. Therefore, the purpose of this study is to draw a Scientific Map of stem cells area (co-word analysis) based on the papers indexed in Web of Science database in selected countries during the years 2011-2013.
Materials and Methods: This study is based on descriptive method, and it was conducted by scientometrics and co-word analysis technique. In this study, 34,142 articles were analyzed from Web of Science database. The search system of Web of Science is a tool for collecting data. Data analysis was done using Web of Science analysis system and CiteSpace software.
Results: Most productions in stem cells are in English and belong to America. Stem cell, cell differentiation, in vitro, gene expression, mesenchymal stem cells, embryonic stem cells and transplantation are the most frequently used words and hot topics in this field.
Conclusion: The growing trend in this area has caused different subject fields to enter stem cells areas. Considering the high frequency of embryonic stem cells in the field, it can be said that different diseases such as spinal cord problems and heart diseases can be treated using these cells.

Abstract
Background and Aim: The purpose of this study is the analysis of articles published about the evaluation of medical scientific products in Web of Science database.
Materials and Methods: This is a quantitative research that is based on literature review. The population of the study consists of 55 articles published in valid national scientific journals on the review of medical scientific products of Iran in Web of Science.
Results: The findings show that during 2006-2016, about 35 articles reviewed the scientific outputs of medical universities and the others examined the scientific outputs of a particular subject area, among which pharmaceutical and surgical fields had the most studies. Some 60.6% of the studies were published by specialists in the field of knowledge and information science, and 39.4% by medical specialists. Among universities, Iran University of Medical Sciences, and among individuals, Hafez Mohammad Hassanzadeh Asfijani were recognized as the most prolific. Most researches have been published using Scientometric Approach, and among scientific software, Pajek has been used more. Among the published articles, those with two and three authors were the most.
Conclusion: The articles have been quantitative, and mentioning various methods indicates a kind of confusion in the choice of vocabulary and terminology.

Abstract
Background and Aim: Transgenic species are the ones whose genomes are genetically modified. The transgenic field is one of the areas that has a high importance and position in the world. Therefore, the aim of the present research is to draw and analyze the co-authorship network of researchers in transgenic subject area.
Materials and Methods: The type of this research is descriptive and was carried out using scientometric techniques such as co-authorship network and social network analysis indices. In this study, 23,456 articles by transgenic researchers indexed in the Web of Science database during the period 2010-2019 were retrieved. VOSviewer and UCINET software were used to draw the co-authorship map and analyze the network indicators.
Results: The scientific cooperation network of transgenic researchers was studied and analyzed using macro and micro indicators of the social network. The status of macro indicators was not appropriate and the network was poorly cohesive. So that, the network density was 0.027, the clustering coefficient was 0.834, the diameter was 15 and the average distance was 4.155. In terms of micro-indicators, the status of researchers in the network was determined in such a way that David Ayares had the most cooperation with other members and also Nam-Hai Chua played the most important role in communicating with people from different clusters of the network, finally, Yan Zhang had the shortest distance with other members of the network.
Conclusion: Based on the findings, it can be concluded that the co-authorship network of transgenic researchers has low cohesion and information is transmitted among members at a low speed. With respect to this, status of different researchers in this study was determined, the results of this study can be used to guide future collaborations, and encourage universities and scientific institutes to develop their interactions with each other and further strengthen collaborations. It should also be noted that according to the findings of the study in this field, Iranian researchers were not identified as key individuals in this network, which requires research on the status and position of Iranian researchers in the field of transgenics.
