Outline of Experiment

JAXA and NICT installed earth stations for each prefectural Medical Association where communication line disconnection is expected to occur at a large-scale disaster, and provided Internet environment
using "Kizuna" communication line at “The satellite application demonstration experiment 2015 (disaster prevention training) on the assumption of the Great Nankai Trough Earthquake” conducted by Japan Medical Association.
They also performed the transmission of HD video via “Kizuna” communication line from a vehicle-mounted station owned by NICT, and information sharing with a virtual stricken area, using of the "Disaster Relief Aircraft Information Sharing Network (D-NET)".

Experiment
Results

JAXA installed earth stations at Mie Medical Association and Miyazaki Medical Association, and NICT installed earth station at Shizuoka Medical Association to provide internet environment using "Kizuna" communication line respectively. JAXA also set up an earth station in Kochi Prefectural Office and provided Internet environment using "Kizuna" line to the Kochi Medical Association by installing a long-range wireless LAN line between Kochi Prefectural Office and Kochi Medical Association. NICT provided internet environment using "Kizuna" communication line to Haibara Medical Association ,a virtual stricken site, through the vehicle-mounted station.
At “The satellite application demonstration experiment 2015(disaster prevention training) on the assumption of the Great Nankai Trough Earthquake”, disaster-related information was shared between JMA and each Medical Association using a cloud-based web conference system (LiveOn) and a cloud-based medical information system. Any prefectural Medical Associations in Japan was able to grasp the state of this training using a cloud-based web seminar system (V-CUBE meeting), and to share relevant information.
The video image taken by the HD video camera on the vehicle-mounted station at the virtual stricken site was transmitted to Japan Medical Association and Shizuoka Medical Association via the “Kizuna” line in real-time. Also, it has been proved that the use of D-NET which JAXA is doing research and development was effective in disaster medical service activity.

◆Information sharing by the cloud-based web conference system
Information sharing using the cloud-based web conference system was performed between seven sites (five sites connected by "Kizuna" communication line and two sites of Japan Medical Association and Wakayama Medical Association used the regular communication lines). It was demonstrated that the Internet video conferencing using the "Kizuna" communication line was as effective for information sharing as using regular communication lines.
JAXA also provided image data of simulate flooded areas of Mie, Shizuoka, Miyazaki, Kochi and Wakayama prefecture captured by "Advanced Land Observing Satellite-2(DAICHI-2)". The images were shared on the cloud-based web conference system between prefectural Medical Associations.S

◆Information sharing by the cloud-based medical information system
At the medical association of each prefecture of Shizuoka, Mie, Kochi, and Miyazaki and also Haibara Medical Association, it connected with the cloud-based medical information system via the "Kizuna" communication line, and information was shared. The same system was used at the other 44 prefectural Medical Associations by connecting to the regular communication line and the information was shared.
It was proved that the medical support service using the “Kizuna” communication line could be effectively performed by sharing the patient information by the Electronic Medical Record which is filled in at each local place and the disaster information such as disaster stricken area map between all prefectural Medical Associations.


Disaster information sharing


◆Understanding the disaster situation by HD video images transmission
HD Video images taken by a HD camera from a moving car with the vehicle-mounted station owned by NICT were transmitted in real time to Japan Medical Association and Shizuoka Medical Association. The high resolution hi-vision video images from the vehicle-mounted station transmitted via “Kizuna” communication line which is a high-speed and broadband makes it possible to grasp the situation of a stricken area in detail and immediately. It was evaluated by a participant of this training to be effective in disaster medical services activity.

◆Information sharing by "Disaster Relief Aircraft Information Sharing Network (D- NET)"
D-NET terminal was installed in an official car of the Miyazaki Medical Association, a virtual ambulance, and Japan Medical Association, which uses the regular communication line, and Miyazaki Medical Association, which uses “Kizuna” communication line, confirmed the information car position and the situation of patient transportation which are transmitted through Iridium Satellites Communication from the car.
A staff of Miyazaki Medical Association made a comment that sharing the position of the car in real time is a good thing, and information sharing using D-NET via "Kizuna" communication line was able to demonstrate that it was effective in a disaster medical service activity.
