Publication of materials in the journal is funded by the authors.

The publication fee per page is determined depending on the total volume of the respective issue of the Series; therefore, the final amount is communicated to the authors after the issue has been compiled and prepared for printing / publication.

The fee for DOI (Digital Object Identifier) assignment is USD 1 per article.

If the author(s) wish to receive a printed copy of the journal issue, they are kindly requested to inform the Editorial Office in advance, either at the time of submission or during the preparation of the issue for publication.

The costs related to printing and delivery of a hard copy are borne by the author(s).

Third-cycle higher education students enrolled in state-funded study programs are exempt from any publication fee, provided that the article is authored solely by them, without co-authors.
