Примечание [11]: @ALL Worksho organizers: Please check the preface, in particular the description of your worksh Preface It is our pleasure to present you the proceedings of ICTERI 2019 PhD Symposium being held in conjunction with ICTERI 2019, the Fifteenth International Conference on Information and Communication Technologies in Education, Research, and Indus- trial Applications: Integration, Harmonization, and Knowledge Transfer. The confer- ence and symposium take place in Kherson (Ukraine) on June 12 - 15, 2019. This volume thematically follows the scope of ICTERI and is focused on research advances, information systems technologies and applications, business/academic ap- plications of Information and Communication Technologies, the role of ICT in Edu- cation. These aspects of ICT research, development, technology transfer, and use in real-world cases are vibrant for both the academic and industrial communities. There- fore, giving the floor to young researchers from academia and industry working to- ward receiving their PhD was considered a plausible extension for ICTERI 2019. The Call for Papers of this PhD Symposium was aligned with the thematic scope of ICTERI. It also emphasized that the contributions are sought in the form of extended abstracts explaining and justifying the ideas for PhD projects or short papers present- ing the first obtained results. The authors were encouraged to present the results of their research to prove that their ideas are tractable. Young researchers joined the Symposium to take part in discussions and/or present their papers. They were offered an opportunity to exchange and discuss their research ideas with their peers, supervi- sors, and senior scientists working in the fields within the scope of ICTERI 2019. Overall the PhD Symposium attracted 20 submissions. Out of these, we have accepted 10 high quality and most interesting papers to be presented at the symposium and published in our proceedings. The PhD Symposium would not have been possible without the support of many peo- ple. First of all, we would like to thank all the authors who submitted papers and thus demonstrated their interest in the research problems within our scope. We are very grateful to the members of our Program Committee for providing timely and thorough reviews. We hope that all presented in this volume papers will be presented by authors during Symposium sessions and by discussed the session participants.
