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: The purpose of this study was to analyze the co-occurrence of the terms of medical and laboratory equipment patents in the United States Patent and Trademark Office between 1984 and 2014.
Materials and Methods: This research was an applied study using scientometrics and co-word analyses. The statistical population of the present study included all patents of medical and laboratory equipment registered in the United States Patent and Trademark Office database between 1984 and 2014. As a result, a total of 13424 patents were retrieved.
Results: The results revealed that in terms of frequency, the keyword "Menstrual Fluid" and in terms of co-occurrence, two keywords (Menstrual Fluid and Magnetic Resonance Image Apparatus) were the most frequent ones in medical and laboratory equipment studies. The results of hierarchical clustering with "Ward's method" led to the formation of eight clusters in this area including the following: General Equipment, Rehabilitation Equipment, Dental Equipment, Therapeutic Equipment, Emergency Equipment, Laboratory Equipment, Diagnostic Equipment, and Medical Consumables.
Conclusion: The analysis of the co-occurrence of words revealed the scientific structure of medical and laboratory equipment well. Accordingly, the scientific issues were extracted and the relationship between them was discovered. The maps of co-word analysis showed several changes, sustainability of concepts, and terms related to this field of science.

Abstract

Background and Aim: The purpose of the present study is to map the coronavirus domain citation network to better understand this domain based on all other citation networks. 
Materials and Methods: The present study is applied in terms of purpose, and is descriptive scientometrics in terms of type, which has been done with the all-citation method. In this study, all scientific publications on coronavirus(6980 documents) in the period 1985-2019 AD were studied on April 10, 2020 in the Web of Science database. For analysis and drawing all citation maps, VOSviewer and Excel software were used.
Results: In the field of coronavirus, 6815 documents, 10246 journals, and 40298 authors were identified. Ksiazek(2003) with the acute respiratory syndrome(SARS) topic received 875 citations and won the first place. The most cited documents in the field of coronavirus have 5 clusters; and the first cluster with 201 documents and with the topic of studying the structure of coronavirus is the largest one. Journal of Virology -- with the thematic range of genome structure and replication, virus identification, etc. -- ranked first with 35,383 citations. The most cited journals in the field of coronavirus are 5 thematic clusters, and the first one is the largest cluster with 121 journals and with the thematic domains of health policy, coronavirus, etc. Also, Woo won PCY first place with his specialization in identifying new microbes and emerging infectious diseases, and receiving 1491 citations. The most cited authors in the field of corona virus are in 6 thematic clusters; the first cluster with 195 authors in specialized field of virology and coronavirus is the largest cluster.

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.
