No more Itaewon crowd crush disaster: Safety in dense crowds transformed by ‘KOSMOS’ service with AI reinforcement learning

“The 2022 Itaewon crushing incident raised public safety concerns. In response, we developed KOSMOS, an AI service addressing “”crowd turbulence””. It employs a reinforcement learning-based AI, designed to suggest routes for crowd dispersion and collision minimization. Our model’s effectiveness in suggesting safe, efficient routes was verified through a simulation that recreated the Itaewon incident using Seoul’s road data. The KOSMOS …

Effects of Compounds in Life on Antibiotic-Resistant Bacteria

Chemical stress on compounds was pointed out as one of the causes of bacterial antibiotic-resistance and observed in S. aureus whether various substances in daily life affect changes in the antibiotic-resistance. It has been confirmed that pesticides and heavy metal ions such as Cr ion affect antibiotic resistance. In addition, even though each of the two substances that does not …
