Introduction: Assessment of the citations to scientific researches and journals by invention patents is a way to analyze the relationship between the science and technology. The purpose of this research was to investigate citations to English-language journals approved by Iranian Ministry of Health and Medical Education in patents registered in the United States Patent and Trademark Office (USPTO) database.Methods: This descriptive survey was conducted based on citation analysis and scientometrics techniques. The study population included 268 English-language journals approved by the Iranian Ministry of Health and Medical Education. The title of each journal was used to search at the USPTO database.Results: 207 patents cited to 49 English-language journals approved by Iranian Ministry of Health and Medical. Note that 65% of patents in this group were in the class A (i.e., human necessities). Most patents citing Iranian medical journals belonged to the United States, and were assigned by Stanford University.Conclusion: Iranian journals, using the necessary processes and strategies according to their policies, can have a better internationally position in terms of article status and being technology-centered. Therefore, due to the increasing publication rate of articles in the country, their quality should be considered (focused on) more than quantity.

Introduction: Since chronic heart failure is considered as one of the main causes of death around the world, it is necessary to map the intellectual structure of studies in this area. This study attempted to map the knowledge structure of chronic heart failure using document co-citation analysis.Methods: Bibliometric methodology and social network analysis were used as the research methods. The study population comprised 11967 records in the field of chronic heart failure published during the period of 2000-2015, which were retrieved from Web of Science database. The correlation matrix and hierarchical clustering were used for document co-citation analysis.Results: “Anker SD”, with 194 papers, was the most productive researcher in chronic heart failure. Again, “Anker SD”, with 12820 citations, was the most cited scientist in this field in Web of Science. “Bristow M” and “Cleland J” were the most frequent co-citation pairs within chronic heart failure, with 634 co-occurrences.Conclusion: The intellectual structure of knowledge in chronic heart failure is an evolving structure, and the clusters identified in this study can be included in the curriculum of the field. Furthermore, these results can help policymakers to identify both unaddressed and matured topics.

Introduction: Citation is the fundamental principle of research compilation; therefore, researchers and their organizations always try to increase their citation rates by means of attracting other researchers. This study aimed to evaluate the quality of the scientometrics indicators of the researches done in Iranian type-one universities of medical sciences.Methods: This was a descriptive study with the scientometrics approach. A full-scale method was used in this research and frequency, percentage, and mean were used to describe the data. The research population consisted of articles which cited articles from researchers in Iranian type-one universities of medical sciences on the Web of Science Database from 2010 to 2014.Results: During the years 2010 to 2014, with increase in the number of articles, the average rate of citations to the articles had increased significantly. Although the average citation per article was low, the citation rate was acceptable (between 1 to 3 percent).Conclusion: The results of this research can be useful for reducing the barriers of obscurity and citation which are the most important factors in the growth of the scientometrics indices of the articles produced by high-level researchers in medical sciences in the country.

Introduction: An important aspect in the evaluation of scientific and research products is citation. Yet, a percentage of citations consist of self-citations, which, when employed excessively, although increases the impact factor (IF), leads to the demotion of journals. This study aimed to investigate the correlation between self-citation and impact factor in Iranian journals indexed in the journal citation reports (JCR) of the Institute for Scientific Information (ISI).Methods: This applied survey was conducted using document analysis method. Samples included 44 Iranian journals indexed in JCR of ISI by the end of 2014. The data were collected via filtrated output for Iran from the ISI database. Data analysis was performed using Pearson correlation coefficient in SPSS software.Results: The 44 studied journals had 6004 citations (mean = 136.45). Moreover, 43.18% of the journals showed a rate of 21%-69% self-citation, to the extent that after removing the rate, their impact factor decreased significantly. Pearson correlation coefficient revealed a direct significant relation between self-citations and IF (P < 0.001).Conclusion: The self-citation rate of the studied journals is rising in ISI. There is a direct correlation between their self-citation rate and IF. Although self-citation is to some extent acceptable, its sharp increase will result in the devaluation and deterioration of the journal. It is suggested that in order to increase real citation of journals, the use of improper methods to increase IF are avoided, and instead, studies are shared on international scientific networks.

Introduction: International scientific collaboration is one of the important aspects of scientific collaboration and study of different aspects of it is conducive in demonstrating scientific communication behavior of faculty members. Findings of its study can be used in policy making, strategic management of research and paving the way for collaboration. Regarding that, this research is to study international scientific collaboration among Shiraz University of Medical Sciences faculty members. Method: Research method was citation analysis and research type was applied. This study was carries out on the articles published by researchers affiliated with Shiraz University of Medical Sciences in WOS from 2005–2011. Data were examined and modified in Excel which resulted into 338 records. Findings were analyzed with descriptive statistics (frequency charts) and inferential statistics (Spearman Correlation) in Excel software. Findings: Based on the results, there were 338 internationally published articles which constitute 11.6 percent of all of the articles (2893) published in WOS during 2005-2011. Spearman test of correlations showed a weak and non-significant positive correlation between the rate of the growth of all of the articles and internationally authored articles (rs: 0.344, p value= 0.544). The most number of collaborations were with US, Australia an England respectively. Overall, 313 faculty members wrote their articles with international collogues. Results: In general, the rate of internationally collaborated articles grew during the timed studied. However, the proportion of their growth in comparison to the growth of all articles is small. Non meaningful correlation between them could show that the growth of all articles is not a result of the growth of internationally collaborated articles and vice versa.

Introduction: The production of Every country`s Medical journals is one of the sign of health development in it. The number of citations in international indexing is a sight of its important in distribution of health information. The rate of self-citations is more been seen. There, the aim of this study had been the comparison of Author self-Citation effect on Impact Factor in Iranian English medical journals in Web of Science (WoS) and Islamic World Science Citation Center (ISC). Methods: By citation analysis, 12 journals in WoS and 26 in ISC were studied from 2006 to 2009. Impact Factors were extracted from JCR, and self-Citaions were obtained by looking of citations in every database and imported to spread sheets. Impact Factor without self-citation recalculated. Data analyzing tool was SPSS software 20 edition. Wilcoxon test was used for comparison of self-citation rates in common journals, and for uncommon journals Mann-whiteny test was used. For correlation test of Author self-citation with IF in WoS Pearson test was used. Because of skewed data in ISC, Spearman test was used. The comparison test of correlation between two databases was Covariance test. Results: There wasn’t any significant deference between Author self-citation rate in two databases (p>0.05). In WoS, the correlation between Author self-citation and Impact Factor was near to meaning surface (p=0.06, r=0.69). The correlation was not meaning in ISC (p>0.05, rsp =0.06). There was significant deferent between the relations of Author self-citation and impact factor in two databases (p<0.001). Conclusion: The effect of Author self-citation in increasing of IF is more significant in WoS. Author self-citation must be decreased to show the really journal´s impact.

Introduction: Scientific documents indexed in citation indices could show the scientific production of an academic institution if the author introduces him/her as a member of that institution. Researchers and faculty members should know about their standard and correct affiliation to declare it in their articles. Nonstandard affiliation could make problems in counting scientific production which can lead to unrealistic wrong place in universities ranking. Identifying scientific documents with wrong affiliation could help the university to correct them in order to reflect more realistic view of scientific production. Methods: This study has been done in a cross-sectional descriptive survey. Research community was 761 documents produces by researchers of Shiraz University of Medical Sciences which is indexed with nonstandard affiliation in Scopus and Web of Science till 2011. As a keyword, "Shiraz" was searched in "affiliation" field in both citation indices. All the documents with nonstandard affiliation were assessed according to their number of citation, subject and type of documents. The results were analyzed with descriptive statistic methods and Excel software. Results: Publication trend of documents were ascending till 2008 and 2009 and then descending. Most of these documents have been cited between zero to 10 times, the least one has a number of 51 to 60 citations. The highest numbers of these documents are original articles. Conclusion: Presence of significant number of documents with nonstandard affiliation shows importance of establishing of accurate policies for the integration of the organization's name and detailed information to investigators to prevent the continuation of this trend. Fortunately however, this trend has been declining in recent years, which may reflect establishment of such a policy and pay attention to this matter.

Introduction: Scientometric indicators are used for measuring and evaluating the quality and quantity of scientific productions in the scale of individuals as well as institutions. The database of Web of Science (WOS) is one of the most prestigious international databases for analyzing scientific publications. This study aimed to determine the relationship between qualitative and quantitative indicators of scientific productions originated by Iranian universities of medical sciences indexed in WOS during 1999-2008. Methods: Using an analytical method, the quality and quantity indicators of publications originated by Iranian universities of medical science were analyzed. Data collection tools were the checklists that we designed in Microsoft Excel. The validity of the checklists was verified by experts. All dissimilar forms of university names were retrieved via Hist-Cite software. The search strategy was conducted based on the obtained various universities names in the WOS database. A total number of 15856 documents were retrieved. SPSS16 was used to analyze the data. KruskalWallis and Spearman tests were used to calculate the chi-square values. Results: Analysis of data indicated a significant difference among three types of universities of medical sciences in the term of quantitative and qualitative indicators. Moreover, the Spearman tests showed a positive and significant correlation between quantitative and qualitative indicators. Conclusion: The study indicated that the universities which produced a greater number of scientific productions also had more favorable conditions in the term of quality attributes such as citations and H-index. This may suggest that the universities have taken into consideration not only the quantitative but also the qualitative aspects of publications
