After careful consideration regarding the pandemic in China, the local host and the organizing committee decided to postpone the ICCT 2022 Conference to October 18-20, 2023, renaming it ICCT 2023. The new website homepage is www.icct2023.com and the event listing on the IASS website has been updated.

SEWC Presidents
R. Sundaram (India) was the association’s president from 2007 to 2022. At the SEWC Board Zoom meeting on May 6th, 2022, Professor Akira Wada (Japan) was elected as the new SEWC President.

SEWC Congresses
The 8^th SEWC Congress to be held in Shanghai, China, in 2021, due to the Covid-19 Pandemic situation, was postponed to October 2022. Unfortunately, the conference was again delayed to the year 2025, and it will be the 9^th edition of the SEWC Conference. The SEWC South Korea Group will conduct the 8^th SEWC Congress in Seoul in 2023. The 10^th SEWC Congress will be organized in Wroclaw by the SEWC Poland Group in 2027.

SEWC Website
The current address of the SEWC website is suspended. A new SEWC website is under construction.

The deadline for submission of abstracts for IASS/APCS 2022 has been extended from the original date of 31 January to 31 March. Note that this extension applies also to Hangai Prize applicants (see Hangai Prize Page).

For more information, see either the symposium website http://www.iass2022.org.cn/ or the appropriate entry in the Events page of this website.

A decision has been made to hold the IASS/APCS 2022 Symposium in hybrid online and in-person format. All delegates from outside China should pay the online registration fee, and then pay the remaining fee if and when they have met the requirements and can enter in accordance with China's epidemic prevention regulations.

The earlybird registration deadline is 30 June 2022. See the symposium website http://www.iass2022.org.cn/ for full information about registration and the fee structure, including reduced fees for IASS members.

At the 2021 Annual Symposium, the Tsuboi Award for the best paper in the Journal of the IASS in 2020 was conferred to:

Ch. Robeller and N. von Haaren (Germany): "Recycleshell: Wood-only Shell Structures Made From Cross-Laminated Timber (CLT) Production Waste," J. IASS, Vol. 61 (2020) No. 2, n. 204 June, pp. 125-138.

There was only one award for 2020, because the Symposium award was not conferred since the 2020 symposium was postponed until 2021 due to the Covid-19 pandemic.

The Hangai Prize Committee announced the winners of the 19th Hangai Prize, and their papers were presented at the 2021 Annual Symposium:

• Ting-Uei Lee (Australia): "From ruled surfaces to elastica-ruled surfaces: New possibilities for creating architectural forms"

• Kotaro Sempuku (Japan): "Self-folding rigid origami based on auxetic kirigami"
  
• Xiuming Liu (China): "Study on thermal damage of large-span ice shell structure based on thermal-mechanical coupling"
• Qian Zhang (China): "Programmable and reconfigurable surfaces with kirigami-inspired bistable elements"

The papers will be included in the December 2021 issue of the Journal of the IASS.
