Socialfest, organized by Karabük University, increases the interest of our country`s youth in scientific activities. This facilitates the integration of original scientific thinking and the scientific production process into the lives of young people and makes it easier to apply scientific production to daily life. Problems and issues facing human and social life can be addressed from a scientific and practical perspective thanks to Socialfest. Thus, it will contribute not only to academic development but also to spiritual, social, and cultural development. Socialfest 2026, which will be organized jointly with Istanbul University this year with the aim of leading the way in building a society where people can live in peace and harmony by producing social models that will meet the needs of Turkey and the world both today and in the future, is accepting applications for its model design competitions, which are structured under four categories: The Turkish Century, The Turkic World, Theology, and Health. Applications are open until April 1, 2026. The information book and promotional images for the Socialfest 2026 model design competitions, which will take place on May 10-11, 2026, are attached.
