All abstracts should be submitted via the online abstract submission system. Abstracts submitted by post, fax or mail cannot be accepted. All abstracts must be submitted and presented in English. When submitting the abstract, the author can choose the preferred presentation method. You can submit more than one abstract in the same abstract category or different abstract categories. The corresponding author and presenting author must be identified when submitting an abstract. Changes cannot be made after the submission of the abstract. Please ensure that your abstract does not contain spelling, grammar, or scientific mistakes, as it will be reproduced exactly as it is.
