Toward Getting IF

The Impact Factor (IF) is an indicator of how many citations an article has received, and is published annually by Clarivate Analytics for selected journals [1-3]. RPT journals are not yet assigned an IF, but they are included in the company’s Emerging Sources Citation Index (ESCI) database, which is used to calculate the IF. According to the publisher’s own calculations, the latest estimate is 1.427 (2019), and more citations are needed. If the journal becomes a journal with IF, more excellent academic papers will be submitted than ever before, and it will be transformed into an academic journal that is even more highly regarded internationally.
In order to achieve this, we need to develop the RPT journal by ourselves. We hope that you will submit your excellent research results to RPT for future publication. We also hope that you will make use of our recent publications when you write your academic papers.

List of citations for papers published in RPT

The Impact Factor (IF) is calculated from the number of citations for the two years following the year of publication and the year after that.
The list of the number of citations for papers published in each year is as follows
