*The Reviewer Performance Score (RPS) is determined as follows for reviewers who made at least 6 reviews in 2020 (review time limit, 14 days):

*RPS= [(Number of reviews completed within 1 week) × 2 + (number of reviews completed within 2 weeks) × 1 + (number of reviews completed within 3 weeks) × 0.2] × quality of review (average) – (number of declined reviews) + (number of editorial comments published in the Journal) × 10.

The review quality of reviewers was evaluated for each manuscript by an Associate Editor who was in charge of the manuscript (range: 1~3) and the average score used.

The above Reviewers will be awarded by the Japanese Circulation Society with a Certificate of Achievement and an honorarium.

In the year ahead in 2021, we expect a steady increase in the number of submissions, as well as an increase in the scientific impact of the Journal.
