No Show Policy 未参会政策
                           For each accepted paper, at least one author or 
							qualified proxy needs to register for attending the 
							conference, and present the paper in the assigned 
							session, either in an oral or as a poster. Publisher 
							reserves the right to exclude a paper from 
							distribution after the conference, if the paper is 
							not presented by the author at the conference. No 
							refund of the paid fees may be claimed by the no 
							show author.
							
							For poster sessions, if the speaker is not present 
							in front of the poster for most of the time during 
							the poster session, this also implies the paper was 
							not presented.
							
							The presenter should start all necessary procedures 
							and approvals (e.g., travel funding, visa 
							application) after receiving notification that the 
							paper is accepted for the conference.
							
							If the authors have, or anticipate, unforeseen 
							circumstances endangering or preventing the 
							presentation, they should notify the conference 
							secretary as soon as possible with proof of their 
							restriction. Substitute presenters may be possible.
