Dear colleagues,

A new coronavirus infected over ten thousand people and hundreds of lives have been taken. The tragic numbers are still increasing every day. The virus occurs mainly in China but also spreads internationally. On 30 January 2020, the World Health Organization declared the virus as a Public Health Emergency of International Concern (PHEIC) but the restriction of travel is not recommended. Very strong measures have been applied all over China to prevent the infection and to treat the infected.

We still hope that the virus would be eliminated in time and our conference could take place as scheduled. We are closely watching the development of the infection and keeping contacts with relevant authorities. At the present, please do not book your flight and hotel until the end of February when we will make the final decision on whether the conference should be postponed. The early bird registration can also be extended.

Please feel free to contact me or anyone of the organizing team for any assistance.



Please register with relevant payment before Jan. 31, 2020. Advance registration is requested for participants who want to present their papers at the conference. Otherwise, their papers will not be included in the presentation program of the conference. On-site registration will be available at the registration desk during the Congress, but it is only for participants without presentation.
