On 28-29 May 2022, we had three oral presentations about our research results at the annual meeting of Japan Associaiton of Fire Science Engineering (JAFSE). This is the first time for oral presentation at the academic society for Mr. Ito and Mr.Suematsu, who are 1st grade of graduate students. Although we have not always completely feel the mood of presentation at the academic society because of online, we have done nice presentation with some degrees of pressures. Mr. Nakazawa, who are former graduate student of our laboratory (graduated at March 2022, present affiliaition: Tokyo Metropolitan Industrial Technology Research Institute) also presented his research results conducted at our laboratory in his master's course. I hope that this expeience is good for their life. We aim to improve our research considering precious questions and comments received at this meeting.
