1.3 Location:
Nerima Culture Center (tent set up in parking lot)
1-17-37 Nerima, Nerima Ward, Tokyo

1.4 Details of display:
IAA System

• Video presentation showing explanation of IAA System using notebook computer
• Demonstration of IAA safety confirmation information registration and search using mobile phones (FOMA)
• Panel presentation (4 panels)
• Distribution of pamphlets

1.5 Goals:

• To draw attention to the presence of the IAA Alliance through presentations
• To confirm the feasibility of replication between Monster IAA and NetStar IAA

Also, to obtain basic data for use in future safety confirmation data exchanges.

1.6 On-site response:
The IAA Alliance participated in the 2002 Tokyo Nerima Ward Comprehensive Disaster Prevention Drill, offering a video presentation of the IAA System and a demonstration of IAA safety confirmation information registration using mobile phones. There were relatively few visitors (less than 100) at the site, partly because this drill was held on Disaster Prevention Day, and evacuation drills were being conducted in many locations. The visitors received explanations using panel presentations, and also viewed a video presentation of the IAA System and a demonstration of IAA safety confirmation information registration using mobile phones.
We also distributed pamphlets encouraging participation in a test of safety confirmation information searches using the IAA System.

1.7 Observations regarding on-site response:
Contacts were made immediately before the event, so one point for reflection is that various persons involved were contacted with very little notice. There were few accesses to the IAA system, so increasing the number of accesses remains an issue for the future.

2.1 Report of operation results:
We tabulated the registrations from September 1 to October 7

Total number of registrations from Monster IAA	55
Total number of registrations from NetStar IAA	102
Total	157

The graph in Figure 1 shows the number of registrations day by day. Note, however, that this data was tabulated based on a log for NetStar IAA.
The number of registrations on September 1 was considerably larger for NetStar IAA (NIAA) than for Monster IAA (MIAA). This is because of inadequate settings for MIAA, which resulted in poor coordination. Among the main reasons for this were:

• Data was not transmitted from MIAA.
• The disaster ID handled by MIAA was incorrect. For this reason, data registered from one location could not be searched from another location.

These problems were resolved by around 11:00 on September 1.

2.2 Points for reflection and issues for the future

• There were inadequacies in the operation system for IAA Alliance as a whole. Regarding collaborations, it was confirmed in a preliminary rehearsal that there were no problems, but the system for handling problems was insufficient, and as a result it took time to resolve these problems.
• Verification tests between two systems were successful, but further studies will be required regarding operation policies, methods, and other issues in the case of links among three systems or more.
• At this event, we decided on provisional specifications to enable the exchange of the minimum information required for safety confirmation. In the future, however, it will be necessary to conduct open discussions to establish specifications for information to be exchanged.
