Purpose – The purpose of this research is to suggest researchers to know the standards of research ethics violation and eliminate the researchers’ anxiety for the possible cases in violation of research ethics through the notification on the web site with online paper submission system for over the last year. We have made an effort and achieved the most exemplary and leading position in the academic journals, however, not satisfied with this, we will endeavor to strengthen it. Research design, data and methodology – Plagiarism and overlapping publications are the most serious problems in research ethics. Therefore, it is necessary to verify the submitted articles making use of paper similarity test programs such as copy killer, KCI test, etc. Editorial board and reviewers should present clear evidences and notify contributors on research ethics violation after close review the contributors’ article content. Results – This research focused on the submitted articles which were verified as research ethics violation, and categorized them into 7 cases. Conclusions – With analyzing the verified 7 cases from KODISA journals, this research will examine closely the verification system and regulations in the current academic research ethics. Afterwards, this research will seek for solution to the problems and make an effort to get improvement for them.
