Repeated publication of papers refers to submitting published papers to other academic journals or conferences for publication without making substantive changes or supplementary research. This kind of behavior is regarded as academic misconduct, which violates the academic requirements for originality and independence. The direct publication of master's thesis is not regarded as repeated publication, because master's thesis is usually written to fulfill the degree requirements, which is different from the originality required in academic journals or conferences and can be regarded as a degree thesis. However, if the master's thesis has been published and marked with corresponding citation information, submitting to other academic journals or conferences again may lead to copyright disputes or academic ethics problems. Therefore, when deciding whether to publish a master's thesis, it is best to consult the requirements of tutors or academic institutions.
