Recording act is prohibited in the presentation halls at Special Lecture, Symposium, Tanabata (Star Festival) Seminar, General Presentation, and Poster. The decision was made under consideration of that unpublished latest data may be restrained by the speakers because of the act. We ask for your understanding and cooperation. We hope the restriction makes presentations include unpublished latest data and have active discussions. In addition, when a recording act without permission is found, the staff will confiscate or erase the data from the recording medium. Please understand the reason and we ask for your cooperation.
