Submission and Closing of registration

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. If the authors submit to the OJS system without passing presubmission, the manuscript will be directly rejected.
