Distinguished scientists, we are glad to meet you in the fourth gathering of our congress. We would like to thank you for the deep interest regarding national and international participation, enriching the literature with scientific papers through discussion and opinion exchange of experts. The verbal and poster papers presented in our Congress will be published in the relevant journals on condition that the papers are edited according to the publication principles of the journals and uploaded to the websites of relevant journals following the evaluation process of editors and referees. The unilateral authority in publication of the papers belongs to the editors and administrators of relevant journals. There isn't a certain condition about the publication of papers in these journals. The papers considered to be suitable for publication after the referee evaluation process will be published in the journals. Thank you for your understanding.
