The ethical policy of IJOPEC Publication follows the European Code of Conduct for Research Integrity (
Authors must be honest in presenting their results and conclusions of their research. Research misconduct is harmful for knowledge. It could mislead other researchers.
Reproducing text from other papers without properly crediting the source (plagiarism) or producing many papers with almost the same content by the same authors (self-plagiarism) is not acceptable. Submitting the same results to more than one journal concurrently is unethical. Exceptions are the review articles. Authors may not present results obtained by others as if they were their own. Authors should acknowledge the work of others used in their research and cite publications that have influenced the direction and course of their study.
IJOPEC is a member of CrossCheck, a multi-publisher initiative to screen published and submitted content for originality. All manuscripts submitted will be checked for plagiarism (copying text or results from other sources) and self-plagiarism (duplicating substantial parts of authors’ own published work without giving the appropriate references) using the CrossCheck database. Plagiarism is not tolerated.
All authors have an obligation to inform and corporate with journal editors to provide prompt retractions or correction of errors in published works.
