All manuscripts sent for publication on JTDA will first be checked for plagiarism percentage using Turnitin's online plagiarism detection facility. If less than 20% are detected, the manuscript can still be accepted and continue in the review process. However, the percentage of plagiarism content equals 20-25%. In that case, the manuscript will undergo a more profound examination process to assess whether it violates ethics and copyright and allow the author to correct and resubmit. However, in manuscripts detected by more than 25%, either those that have just been received by the editorial team or those that have been accepted again after the revision stage, the manuscript is declared to have violated ethics and copyright. The manuscript will be returned to the author for another opportunity to revise it again, or possibly others will be rejected.
