Dear Participants of ART 2021,

I hope you had a pleasant and safe trip back home.

It was great pleasure and honor for me to have you with us at ART 2021 as a hybrid conference offering both onsite at Phoenux Jeju, Jeju, Korea with virtual version in parallel during last November 10~12, 2021. On behalf of the Organizing Committee for this conference, I would like to express my sincere gratitude for your active participation and involvement in the conference.

This ART was an overwhelming success, attracting more than 200 delegates, speakers, and sponsors from around 10 countries and provided great intellectual and social interaction for the participants. I hope that all participants had a meaningful time listening to the presentations and having fruitful discussions on scientific and technological issues with experts from all around the world. I also hope that the conference provided you with a good opportunity to build up ever-lasting friendships with many participants.

Without your support, the conference would not have been as successful as it was. I trust that you found your involvement in the conference both valuable and rewarding. The photographs taken during the conference are now available for download on the website at www.art2021.kr, and you can enjoy and share the memories about ART 2021, Korea. 

Once again, I would like to convey my deepest appreciation for your contribution and wish you good health and happiness in the years ahead, and I hope to see you all again in the next ART conference soon!

With best regards,
