1. The 13th Summer Research Presentation of the Arctic Technology Research Committee The 13th Summer Research Presentation of the Arctic Technology Research Committee held online sessions (Webinar) on August 26 (Thursday), with about 40 members from the relevant industries, academies, and research institutes present. It started with the opening remarks from President Choi Kyungsik, followed by the congratulatory remarks from the SNAK President Kim Hyunsoo. After this, the special session for a retirement ceremony and the special sessions #1 and #2 on a seminar about polar regions were conducted. The first special session was the retirement ceremony for Prof. Nho Insik of the Dept. of Naval Architecture & Ocean Engineering, Chungnam National University, and it proceeded with the presentation on the "Current Development and Status of Ice-Ship Collision Analysis Method." Prof. Noh Insik, in particular, has been conducting his researches on the destructive strength of ice since 1987 followed by the technical development of the shock threshold structural design and ice-structure collision simulation, the assumption on the safe cruise speed of a ship through the ice collision simulation of a ship in the polar regions, and others. The next special session introduced the preliminary feasibility upon the next-generation icebreaking research vessel by Jung Youngsun, Senior Researcher at the Next-Generation Icebreaking Research Vessel Construction Agency of the Korea Polar Research Institute (KOPRI), who presented the concept, basic structure, and development plans for successful vessel construction. This provided that securing a next-generation icebreaking research vessel will greatly contribute to overcoming the limitations of current arctic researches and enhancing Korea's arctic study level. The special session that followed this introduced the types, crystal structures, and growth process of sea ice on the theme of the "Sea Ice in Polar Regions" by Prof. Choi Kyungsik of the Dept. of Marine Engineering of Korea Maritime and Ocean University, and this helped the audience to understand the characteristics of Arctic sea ice with various image data. In addition, the following presentation was about the characteristics of ice applied to the hull during the icebreaking, which was about the "Technical Development of the Assumption on a Real Time Ice-Load based on a Simulator," by Prof. Kim Yooil of the Dept. of Naval Architecture and Ocean Engineering of Inha University, and the audience could understand the direct analysis method and characteristics of the semi-analytic method through this lecture. The last special session conducted was a lecture on the theme of the "Application and Prospect of the Fourth Industrial Revolution Technologies in the Russian Arctic" by Dr. Jeong Seongyeob, KRISO, who explained the concept and characteristics of the industrial revolution and then introduced the future of the new industrial revolution in the Arctic. Chart 1 below organized the information about each lecture and the corresponding speaker for this Summer Research Presentation. To construct the next-generation icebreaking research vessel successfully, it is planned tocommence the precedent development projects on hull form optimization, equipment cold-resistance evaluation, ship monitoring technology, and ice sea trial with a budget of KRW 2 billion starting 2022. Hence, we hope that the president’s group and the steering committee, which will be organized next year, will actively participate in the said development project for the next-generation icebreaking research vessel construction, and that this research committee will become a leader in the field of Korea's polar region research by taking actions for the future research demands in the Arctic.
