The similarity rate of the work done should be submitted to the editorial board as a report by the author(s). The upper limit of acceptable similarity rate is 20%. When it is determined that the upper limit of the similarity rate is exceeded, the editorial board rejects the article in question.
The editorial board may use various "plagiarism control" software or programs (such as iThenticate) to check the originality of submitted works.
Suppose plagiarism is detected by both the referees and the editorial board at any stage of the submission (before or after acceptance, at any stage before publication). In that case, the editor may warn the author(s) and request rewriting and/or appropriate citation of the submission. If the plagiarism rate is more than 20%, the work may be rejected, or the institution(s) of the author(s) may be notified of the plagiarism rate. If plagiarism is detected after publication, this situation is disclosed to the readership as an editorial note in the journal, and the author(s) institutions are notified of this violation rate.
