Ethical Principles and Publication Policy

The author may request that certain individuals not be referees due to conflict of interest.
Since it is not possible for the Editor to know all the factors mentioned, referees are expected to inform the Editor of any situations that will prevent them from making a fair evaluation.
No matter how much effort the Editor puts into a research, he/she may not notice any violations of publication policy or ethical problems. It is very important for expert referees to warn the Editor when they encounter such situations.
