The hi-index proposed by Batista et al. in 2006 is one of the complementary indicators of the h-index based on the role and status of authors. In this article, we will introduce this indicator and its features.

The Scientific Quality Index (SQI) was proposed as a qualitative index in 2017 to evaluate the scientific outputs of researchers. In this article, in addition to introducing this index, the results of the most recent researches using this index are mentioned to provide the necessary background for related researches within the country.

Today, scientometrics is the main method of assessing and comparing the scientific publications of countries, universities, scientific institutions, specific subjects and authors. The aim of this study was to evaluate the Iranian scientific outputs on thalassemia based on scientometric indicators. In this scientometric study, the social network analysis was used to investigate the co-authorship, word co-occurrence and collaborative coefficient. The study population included 476 articles on thalassemia, indexed in the Web of Science (WoS) from 2006 to 2016. Excel ،Raver-matrix ،SPSS19، UCINET 6/28، Netdraw 2/141 and VOSviewer were utilized for data analysis based on scientometric indicators. The growth rate (27.94%) suggested that scientific outputs on thalassemia had an increasing trend in the WoS. Mean collaborative coefficient was 0.78, and the findings showed that there was a significant relationship between the number of authors and citations to each paper (p=0.05). The Pearson correlation coefficient was 0.650, indicating a direct and positive relationship among the studied variables. However, the co-authorship network of authors and institutes with density of 0.006 and 0.015 indicated low coherence of researchers' network in the field of thalassemia. In the field of thalassemia, both scientific outputs and scientific cooperation level have increasing trend, but compared to other fields, the collaborative network has no good coherence, and it is a great way to achieve the desired status.

Various scientometric indicators have been developed for quantitative and qualitative evaluation of scientific output. Each of these indicators has its own weaknesses and strengths. The study aimed at using the keywords as a qualitative evaluation instrument in research of many scholars of Medical Sciences University. This study was conducted as a cross-sectional study within a 6-year period (2005-2010). The research population included all papers published by faculty members of Medical Science University of Babol who were as the first/corresponding authors with at least 2 papers and these indexed articles in periodicals published in WOS during this period. The data were collected by means of a tailor-made data collection sheet. The repeated or synonym keywords were collected from different papers of an author and were analyzed in terms of repetition for qualitative evaluation of the research of every scholar. The data were analyzed by using descriptive statistical indexes and statistical software spss version16. During this period, 127 articles have been indexed in WoS database from researchers of this University. in 11 articles of 300 words, 21 repeated words or synonyms were used by 25 researchers who had two or more than two papers. By considering these findings, the overall ratio of articles with repetitive keywords was 16% and the proportion of repeated keywords to whole words was 7%.Statistical processing of the data using linear regression indicates an inverse relationship between the number of articles of each author and repeated keywords or synonyms in his/her articles. So, by increasing the number of articles for every author from 2 to 5, the repeated words in per article were decreased to 0/83, 0/77, 0/25 and finally zero, respectively. low rate of the same keywords and synonyms in the articles of one researcher may be a sign of dispersion and lack of coordination in research activities. Therefore, regarding the coordination and concentration of the subject in scientific activities is very important in assessing the quality of research and researchers.

The recognition and the evaluation of a country’s research status are essential for the country’s research planners and policymakers as well as researchers within that country. Nowadays، the study of the quantity of scientific output (especially research articles and papers) is one of the most important factors in research and generation of science. The Science Citation Index Expanded (SCIE) database is presented by the ISI scientific information center، which is considered an important center in Scientometrics Studies. This study aims to look into the scientific output of Shahrekord University of Medical Sciences (IR Iran) ’ researchers until the end of 2011 using data taken from the science citation index، Web of Science (WOS). The research was application-descriptive. The data were gathered from the internet or from the WOS center. Using different spelling methods of Shahrekord University of Medical Sciences from 1993 to 2011 in the search engine of the center under the heading of SCIE، an extensive search was carried out. The data gathered from this search were entered in the Histcite software. Descriptive statistics، percentages and some scientometric regulations were used to analyze the data. The total number of documents by researchers in the Shahrekord University of Medical Sciences in the science citation index up until the end of 2011 was 142، which were published in 89 different magazines. The total number of references made to these articles was 352، with an average of 2. 48 references to each article and the h-index of the university was 9. The total number of documents by researchers in Shahrekord University of medical sciences in this database increased from 1 document in 2000 to 45 documents in 2011 and the total number of citations made to university articles increased from 1 document in 2004 to 93 documents in 2011. The biggest portion of scientific production was related to general practitioners with 22 records (15. 5%). Scientific output in the Shahrekord University of Medical Sciences has had an ascending trend and the rise in the number of references made to these articles show that the quality has also improved.

One of the most important indicators in scientific output in the world is the number of articles indexed in international and reliable indices. Many scientific institutions perform statistical analysis on countries, institutions and individuals. An Institution of Scientific Information (ISI) indexes the scientific information of most of international scientific journals. Using information on Web of Science we can evaluate scientific output of countries, universities and individuals and compare them with one another. The aim of this study was to assess the status of scientific output of Kurdistan University of Medical Sciences according to scientometric indicators until the end of 2011and compare it with those of other universities within the same rank, in Iran. By use of basic search in Web of Science and choosing SCIـEXPANDED index from 1993 to 2011 different affiliated addresses indexed in WOS for Kurdistan University of Medical Sciences combined by using OR operator, then data were collected and analyzed. Total number of records indexed in WOS till the end of 2011 was 157. Maximum and minimum number of records were 111 (71. 5%) for original articles and 1 (0. 5%) for letter respectively. Maximum number of scientific output belonged to public, environmental and occupational health with 35 (22. 87%), tropical medicine with 24 (15. 68%), general and internal medicine with 21 (13. 75%), pharmacology with 12 (7. 19%), and multidisciplinary chemistry with 10 (6. 53%) records. Each of the other subjects had less than 10 records. Canada had maximum international collaboration with 7 records and Egypt, Philippines, Thailand, each with one record had minimum international collaboration. Maximum national collaboration was related to Tehran University of Medical Sciences with 29 records and Tarbeyat Modaress University with 13 records. 157 records of Kurdistan University of Medical Sciences had been published in 89 journals, among them 23 journals, published maximum number of articles (54%). Only 5 journals were Iranian. Total number of citations was 300 and a median citation per article was 1/91. Average article for every academic member was 1/01. Scientific output of Kurdistan University of Medical Sciences has been on the rise. Increase in citations is indicative of improvement of the quality of the articles in this university.
