All conference attendees must register. The registration categories and rates have changed now that CDC 2020 will be in a fully virtual format. First category includes paper uploads and the rates are substantially reduced. Second category, newly introduced for the virtual CDC, does not include paper uploads and is available at rates even further reduced (see the tables below). Both categories include access to the virtual venue, electronic proceedings, live sessions, and on-demand presentations. A number of pre-conference workshops will be offered at CDC 2020. Access to the workshops is not included in the conference registration. Please see the Workshop Registration section below. Please carefully review the registration and refund policy at the bottom of this page, as refund penalties may apply.

In case of any question about registration rates and/or refund policy, please contact the Registration Chair Professor Yongsoon Eun or the Conference Secretariat.

Member, Non-Member and Life Member registrants may upload up to three final papers.
Reduced rate (Students and Retirees) registrants may upload one final paper.

All accepted and invited papers are limited to six (6) pages. Authors may upload longer manuscript up to a maximum of eight (8) pages total. Each page in excess of six will incur an additional charge of KRW 230,000. Each additional paper is subject to a charge of KRW 230,000.
