The journal's Open Access Editorial Policy is developed based on the recommendations and standards of the Budapest Open Access Initiative (BOAI).

The journal utilises the concept of "open access" as defined in the official documents of the Budapest Open Access Initiative.

By "open access" to peer-reviewed scientific literature, we mean its free availability on the public internet, permitting any users to read, download, copy, distribute, print, search, or link to the full texts of these articles, crawl them for indexing, pass them as data to software, or use them for any other lawful purpose, without financial, legal, or technical barriers other than those inseparable from gaining access to the internet itself. The only constraint on reproduction and distribution, and the only role for copyright in this domain, is to give authors control over the integrity of their work and the right to be properly acknowledged and cited.

The journal’s Editorial Board upholds the principles and values of open science and regards open scientific (research) data as a vital component in ensuring the transparency and reproducibility of scientific research. In its work, the Editorial Board is guided by the FAIR principles (Findability, Accessibility, Interoperability, Reusability), which ensure the discoverability, accessibility, interoperability and reusability of data ("The FAIR Guiding Principles for scientific data management and stewardship").

FAIR Principles: Findable. Research materials must be hosted in a reliable repository and have a permanent identifier (DOI) that allows them to be uniquely identified and cited. Accessible. Data must be accessible via standardised access mechanisms. If there are restrictions (ethical, legal, contractual), authors must clearly state them. Interoperable. Where possible, data should be presented in open or widely used formats that allow for their use in different research environments. Reusable. Data must be accompanied by sufficient description (metadata) so that other researchers can understand the context of their creation and use them correctly.

The publication operates under the Creative Commons Attribution International License (CC-BY). This allows users to read, download, copy, distribute, print, search, cite, or link to the full text of the articles in this journal.

The journal provides immediate open access to all published materials, making research results freely available to the public and supporting a greater global exchange of knowledge. This means the following: every internet user has free and unrestricted access to the full text of articles published in the journal; manuscripts are freely available without subscription or financial barriers; immediately upon publication, all materials are available online (without an embargo period).

The publisher allows the author to preserve (lodge) the final version of the article in an institutional or subject-specific repository, where it is available as open access, thereby ensuring maximum visibility and impact for the publication.

Authors whose articles are published in open access retain all copyrights and grant the journal the right of first publication for original scientific articles containing the results of experimental and theoretical research that are not under consideration for publication in other editions.

The author warrants that the submitted material:

• Does not infringe upon the copyrights of other individuals or organisations.
• Has not been previously published by other publishers and has not been submitted for publication in other editions.

The rights granted by the author to the Editorial Board of the journal include, in particular, the rights to:

• Publish the article in Ukrainian or English and distribute its printed version.
• Translate the article into English (for articles in Ukrainian) and distribute the printed version of the translation.
• Distribute the electronic version of the article, as well as the electronic version of the English translation (for articles in Ukrainian), through any electronic means (hosting on the official website of the journal, in electronic databases, repositories, etc.).

The author retains the right, without prior approval from the Editorial Board and founders, to:

• Use the article materials in whole or in part for educational purposes.
• Use the article materials in whole or in part for writing their own dissertations (theses).
• Use the article materials to prepare abstracts, conference reports, and oral presentations.
• In all cases, providing a bibliographic citation to the article or a hyperlink to its electronic copy on the journal's official website is mandatory.
