Having considered the concept of the programs thoroughly, JDDW has defined symposiums, panel discussions and workshops from JDDW 2015 as follows with the aim of acquiring higher academic quality. (Please note that the Japanese Society of Gastroenterological Surgery (JSGS) applies its own definitions.)

Symposiums (including videos) [Duration of presentation: 15 minutes or longer]

Symposiums are lectures given by presenters, whose achievements have already been recognized to a distinguished degree, in order to present their further development results.

Panel Discussions [Duration of presentation: 12 minutes or longer]

Panel discussion are positioned as sessions where all panelists engage in intensive debates on a specific issue. Panelists take the stage for an integrated discussion (30 minutes or longer).

• Oral presentations at JDDW 2015 (lectures, theme session presentations) must be computer-based. Please prepare them as follows.

  For computer presentations, you can either bring your own laptop, or you can register the data by bringing it on a USB flash drive or CD-ROM. To avoid problems, please bring backup media with you. Other media, such as MO, floppy disk, ZIP or DVD cannot be accepted.

  The presentation data file name should be in the following order:
  (Presentation No.) (Name) (Venue No.)
  Example: [IS-S1-3_H_Hanako Shokaki 8]

  At the venue, the presenters will have to manage the equipment and materials on the podium. There will be no PC on the podium but only a monitor and a mouse.

  Please prepare any handouts of presentation data yourself and bring the handouts with you. The event venues (such as the Operations Center) will not be able to handle such matters on the day.

• The time to end your oral presentation will be signaled by a light. We request that all presenters observe the time limits.

Presenter acceptance

• All data should be submitted to the Operation Center at the venue. Please inform the Operation Center of the venue name and presentation number no later than one hour before your presentation.
  The Operation Center will receive your data and copy it to the server. The copied data will be sent to the presentation venue and will be ready. Please take your seat and wait for your presentation near the seats reserved for the next presenters (at the front left side of the venue). The organizers assume full responsibility for the deletion of the data after the conference.

• Presenters should take seats reserved for the next presenters, immediately after the presenter before you has begun his or her oral presentation.

When bringing your own laptop, please note the following

• If bringing your own laptop, you can use a laptop running Windows (Windows 7, Windows 8) or Mac OS (Mac OS X 10.5 or later [if not bringing your own, Mac OS X 10.6 or later]) with a USB port. Please use PowerPoint only.
• If your PowerPoint presentation file contains video (movie), we recommend that you bring your own laptop (there is a possibility that the laptop made available at the venues may not be able to play the videos). Even when bringing your own laptop, please bring backup data on a USB flash drive or CD-ROM, in case your computer malfunctions. Moreover, please be sure to bring your PC AC adapter.
• If bringing an iPad, Windows 8 touch-panel PC or tablet PC, you will be giving a presentation with it connected via a mini D-sub 15-pin cable (not wirelessly). For an iPad 1, presentation will be displayed only on the external monitor and not on the iPad screen. The PCs made available at the venues do not have touch panels. If you wish to use a touch panel for your presentation, please bring your own computer.
• When bringing your own laptop, the PC video output cables made available at the venues are of the mini D-sub 15-pin type. Please bring a computer that can connect to such cables. Moreover, if an adapter is required to connect to the cable, please be sure to bring your own with you.
• The resolution of the projectors at the venues is XGA (1024×768). Please be aware that if your output cannot match this resolution, it may lead to compromised image quality.

At JDDW 2015, there will be no poster presentations in paper form. They will be conducted using plasma displays.

Features

• You can make presentations with video.
• The presentation data will be registered in advance, via a dedicated screen on the Internet.
• As full high-definition monitors will be used for the presentations, they will have the same reproducibility as paper. You can browse through the presentation topics at any time during the event using PCs at the conference venue.

Presentation display modes

There are two display modes: [Poster Mode] and [Slide Mode]. You can use Poster Mode mainly and Slide Mode partially to zoom in on slides, or use just one of the two modes.

Creating presentation data

• Please create your presentation data using PowerPoint. Compatible versions are 2003 or later. (PowerPoint 2010 for Windows is recommended)
• Do not create large-sized poster data (as in the past); please create each slide individually.
• Please set the slides to fit a 4:3 aspect ratio.
• Use the following fonts:
  Japanese: MS Gothic, MS P Gothic, MS Mincho, MS P Mincho, Meiryo
  English: Century, Century Gothic
• PowerPoint files will be converted to images to keep the original layout. Because of this, slide transition animation effects and animations cannot be used.
• You can use video within PowerPoint. You can register up to a total of 200MB of data (PowerPoint file and video). Video is played automatically when the page that contains video is displayed. Please confirm this operation in advance.
• The number of slides you can register is 14 (please state the "conflict of interest" information on the 15th slide). The title slide (presentation title and presenters' names) will be displayed separately. Please do not include the title slide in the presentation itself..
