Notes for Mac Users: "Play stopped. Recording tool detected."

This message popped up due to the detection about activation of video related software in the meantime.
please recheck that any of video player, recording or screen capture software (e.g. Quick-Time Player, OBS, Zoom, etc) is running in the meantime while you are opening the presentation video on your device. The strongest feature of the media player is blocking such video-sharing related activities (e.g. screen capture, recording, etc.) from users.
Because of all that, the message might’ve been appeared because the player detected such kind of program is running.

Live Online Presentation Session

To promote a greater interaction between the speakers and the audience during the workshop, we have organized a live online presentation session which will be held on May 31 (Monday). Due to the time limitation, 8 papers were selected based on the abstract review results and the authors’ willingness to give their talk live. An online Zoom meeting will be created for the session in which workshop registrants can participate remotely. Each talk will be 15 minutes long including Q&A.
The session starts at 9:00 pm May 31, Korean Time (GST+09:00)
For those who’ve fully registered for the workshop may get the live session link with the password through the online conference page after logging in.
