Because too many articles are under process in IJoST, since August 2022, 
new manuscripts must go through presubmission. Only manuscript that passes 
the presubmission will go through the reviewing process through the system.

Please submit the manuscript for presubmission to ijostpresubmission@gmail.com.

⚠️ Important Notice: Prohibition of Multiple Submissions

We strictly prohibit multiple submissions, defined as submitting the same manuscript
to more than one journal simultaneously. This is a serious violation of publication ethics.

If a multiple submission is confirmed, both the author(s) 
and their affiliated institution will be blacklisted.
Any future submissions from the same institution (regardless of author) 
will be automatically rejected for a defined period (1 year).

This policy safeguards the integrity of the peer review process and 
ensures fairness and accountability across academic institutions.

We urge all contributors to adhere strictly to ethical publishing practices. 
Sanctions will be applied without prior notice upon evidence of misconduct.
