The time allowed for each paper is limited to 30 minutes including discussion; the length of the written version for publication must be agreed with the conveners. Papers offered without special invitation will be selected on the basis of a one-page abstract (300~400 words). Abstracts must be submitted on paper, or preferably in electronic form by e-mail or on disk, by the end of December 2008. Please inform us in which section you would like to read your paper when you submit your abstract. Information about acceptance or rejection of the paper will be given by the end of February 2009 (or by the end of October 2008, if the abstract has been received by the end of September 2008). Invited speakers are requested to send their abstract of paper by the end of May 2009. All abstracts received in time will be published in the abstract booklet.
