ИСТИНА

Dear colleagues, the tenth year of the “Technological Forum” and “Technological Forum Junior”, based on your suggestions and contributions, aims to contribute to the objectives of sustainable development of mechanical technologies. This conference has become a place of traditional meetings of the teachers and the students from technological departments of technical universities and debating the results of their yearly work. The organization of expert and social meetings has also a long tradition. Also the gathering of technological departments has its own tradition. The proof of the meaningfulness is the high quality of the presentations and the papers, increase in the attendance of the participants from the individual departments and the presentation of the new technological research and knowledge. The production with high value-added ideas and responsibilities is the necessary for the sustainable development of our countries in accordance with all of the current and future restrictions and requirements. For this goal the high standard of the education, the skills and the discipline is vital. These attributes are still accepted by the majority of the population in our countries. Let us not give a space to the rest of the population, the minority of indifference. All of the published articles of this year's Technological Forum show rapid development in technologies and requirements for new information. The most important is the mutual cooperation in every field and in every form of education. Topics include up-to-date engineering technologies, materials and other related issues. On Behalf of all organizers I would like to welcome you at the 12th scientific conference “Technological forum 2021”. I would like to thank you for your contribution, cooperation and participation.
