Each manuscript undergoes an initial review, and if it is not written clearly and coherently or does not conform to the guidelines in the current "Requirements for Authors", it may be rejected without review. An author publishing in English, which is not their first language, is encouraged to use a dedicated language editor to review the manuscript before it is submitted to the journal's editorial office.

The received manuscript is subject to double blind review. Within 2 months of receiving the manuscript in the editorial office of the journal, the executive editor informs the corresponding author about the status of the manuscript. If corrections are needed, the manuscript approved after peer review is returned to the corresponding author. The author has 15 days to correct the manuscript and return it to the editorial office of the journal. After the expiration of this period, it is assumed that the author refuses to publish the manuscript. The time for corrections can be extended once after a written request has been submitted by the corresponding author to the editor-in-chief of the journal before the expiry of the 15-day period.

The editors are not responsible for inaccurate citations, including misquoting of website content and copyright infringement.
