Dear authors!

According to international requirements and recommendations for publications of the Committee for Quality Assurance in the Field of Science and Higher Education of the Republic of Kazakhstan, if there is more than one author, it’s necessary to indicate the contribution of the individual author - the CRediT author's statement. CRediT statements must be provided during the site application process and described before the Acknowledgments section. To correctly format CRediT, use Elsevier's recommendations
