ISSN : 2693 6356 2020 | Vol 3 | Issue 3 A Scientometric Study of the Productivity of the Literature in the Engineering and Materials Sciences Mr. MANJULA G, Mr. KRISHNA Associate Professor 1,2 Librarian KLE Society S. Nijalingappa College Rajajinagar, Bangalore-560010 Abstract This report examines the research output of the journal "Indian Journal of Engineering and Materials Sciences (IJEMS)" between the years 2001 and 2018, focusing on a subset of the total 1215 papers published in the magazine. The year 2014 saw the greatest volume of published works. Researchers most often used journal articles as references in their work. There were 10,952 papers published with two or more authors and just 120 published with a single author. The Relative Growth pace of academic communication is 1.99, which means it is growing at an average pace. This study indicates that IJEMS's research output and growth rate of scholarly communication are on the decline, and it also looks at the authorship pattern of this communication using the collaborative index, which is the collaborative coefficient. Keywords: Science, technology, engineering, and mathematics (STEM), and scientometrics Introduction Scientometrics is a field that uses the analysis of scientific papers to learn more about how science works and how it develops over time. The quantitative and qualitative features of a publication are dissected using bibliometric, scientometric, and informetric methods. Quantitative measures of scientific information, such as the number of scientific articles published in a given time period, the citation impact of those articles, etc., are used to examine the development of science in this discipline (Rajendran, 2011)."Scientometrics" is the "application of those quantitative methods dealing with the analysis of science viewed as information processes," as stated by Patra et al. (2006). The Indian Journal of Materials Science and Engineering Launched in 1994, the journal features articles from a wide range of engineering disciplines, including aerospace, mechanical, metallurgical, electrical/electronic, civil, fluid mechanics, instrumentation, and materials science. As of the year 2018, the IF of IJEMS was 0.794 (JCR). (http://op.niscair.res.in/index.php/IJEMS/index ) The mission of the Indian Journal of Engineering & Materials Sciences is to disseminate significant new findings in the theory and application of all branches of engineering and materials science. Aerospace, mechanical, metallurgical, electrical, electronic, civil, and materials engineering are all subfields of engineering. (https://www.niscair.res.in/jinfo/IJEMS/ijems_i nst_auth.pdf). The objective of the Study  To study the growth of research productivity on during 2001-2018.  To examine the Relative growth rate of articles.  To find out the Doubling time of the articles.  To analyses the Author pattern and collaboration like CI, CC, DC, etc.,  To know the ranking of the author. Scope and Methodology The paper represents the scientometric analysis of IJEMS publications in the field of engineering during the period 2001 to 2018. The data is confined to articles on IJEMS. A total number of 1215 articles have been found and the same has been analyzed by using the spreadsheet application. Computed growth rate and collaborative measures using a set of formulas. Analysis and Interpretation of Data Analysis of the data based on the publishing chronological order from the year 2001 to 2018. Using worldwide set of formulas i.e. Log formula and mean value the study analyzing the Author collaboration i.e Collaborative index (CI), Collaborative coefficient (CC), Degree of collaboration (DC) also Average Author per publication (AAPP) and Average publication per author (APPA) etc., also examines the Growth rate of scholarly communication through Relative growth rate (RGR) and Doubling time (Dt).

Findings and Conclusion The Relative growth rate (RGR) has an increasing trend whereas the Doubling time (Dt) has increasing trend. Average doubling time was 0.37 years. The Mean number of authors (CI) was 3.5 Highest author collaborative coefficient is 0.67 in the year 2018. The average Degree of Collaboration (DC) was 0.90. Average author per publication (AAPP) is high i.e. 3.03, Average publication per author (APPA) is very less that is 0.33. There is collaborative research trend in IJEMS. Scientometrics analysis of a subject field helps in identifying the research status. It can be seen whether it is conducting more or fewer research works in a particular field. Through this analysis, one can found subject areas in which research trend is high and the areas where research trend is low; and subject areas where no significant change in research is seen world- wide.
