Mapping the Scientific Structure of Medical and Laboratory Equipment Patents in USPTO database between 1984 and 2014
Maryam Emami, Nosrat Riahinia, Faramarz Soheili,
Volume 12, Issue 6 (3-2019)
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.

Scientometric Study of SMA International Research Outputs
Somayeh Ghavidel, Nosrat Riahinia, Samira Daniali,
Volume 13, Issue 6 (2-2020)
Abstract
Background & Aim: studying scientific outputs by using scientific indices is a useful tool for understanding scientific research. The purpose of this study is to visualize the international research outputs of the SMA subject Area.
Materials & Method: This study is an applied one with an analytical approach and using scientometric indices. The population present in this study includes 4217 WOS records all in the SMA area from 1946 until the end of 2018. The MeSH have been used to identify keywords and Ravar PreMap software for words’ homogenization, VOSviewer, HistCite, and Excel used also.
Conclusion: Ninety-one countries involved in scientific production outputs of this subject area, were among the most influential countries in scientific collaboration. The USA has most of its collaborations with other countries. Of the 946 essential journals identified, HUMAN MOLECULAR GENETICS SMA has got the highest number of citations. Articles in SMA Subject Area with the total number of 6097 keywords have got the 1st rank, of which the “Spinal Muscular Atrophy” has got the highest frequency and the core subject among the nine influential countries. The total number of articles in this area is 8505. Worthy of mentioning, Iran with 58% of the total scientific output ranked nine on the list.
Results: The upward trend of SMA scientific research trend indicates the increasing importance of this area in the world. Due to the the international growth of research in this area and the importance of the participation of international research, researchers in our country should pay more attention to scientific cooperation.

Analysis of the Publication Process in the Field of Road Accidents and Injuries and Visualization of its Scientific Structure
Dr. Afshin Hamdipour, Hashem Atapour, Fatemeh Ghasemzadeh,
Volume 15, Issue 1 (3-2021)
Abstract
Background and Aim: Road injuries are one of the most important public health problems and the leading cause of death and injury all over the world. The aim of this study is to investigate the trend of publication in the domain of road incidents and injuries and to visualize its scientific structure.
Materials and Methods: The present study is of scientometric type, its method is cross-sectional, and it was done during the period of 2005-2018. A total of 6563 records of road accidents and injuries were selected as the statistical population. The data collection tool was the Web of Science database and the HistCite software was used to visualize the scientific structure.
Results: The United States, Australia, and the United Kingdom ranked first to third with the production of 927, 700, and 651 documents, and the records of these three countries received 26373, 24447, and 23733 citations, respectively. Besides, the rank of road accidents and injuries for these countries were 89, 115, and 132, and the rate of casualties per 100,000 populations was equal to 10.6, 4.5, and 2.9. On the other hand, Libya, Thailand and Malawi (in South-Eastern Africa) are ranked first to third in the areas under study. The number of publications of these three countries was 5, 58 and 18, and their rank in document publications was 100, 34 and 65, respectively. 
Conclusion: The relationship between rank in publications and rank in road accidents was negative and significant; countries with higher publications had a lower rank in road accidents and injuries. This indicates an inverse relationship between the number of publications and the number of road injuries; This means that as the number of publications in this field increases, the rank in injuries will improve. It seems that one of the factors that may be effective in reducing injuries and road accidents is the serious intervention of researchers to conduct research in this area in order to raising awareness and create a traffic culture for citizens.
