This study estimates the number of evacuees that can be accommodated in 32 shelters in Bunkyo Ward and investigates shelters' refugee-acceptance preparations. Across shelters, the estimated evacuee number ranges from 500 to 2,500, with 2 shelters having an excess of approximately 1,000 people, who arrive because of house destruction and fires. Some shelters underestimate the number of these evacuees. Regarding the check-in procedure, counter-plans prove insufficient for large-scale evacuations and for shelters that do not follow the local government's policy regarding stranded commuters. Therefore, each shelter must estimate the number of refugees and establish an appropriate situation-based individual system.

In the case of a fire incident such as arson, the combustion experiment that reconstructed the fire scene will be conducted to clarify the facts. However, various problems such as construction costs and securing an experimental environment must be dealt with. Therefore, the purpose of this study is to utilize fire simulation for the investigation of fire incidents. In this study, combustion experiments and FDS (Fire Dynamics Simulator) simulations assuming gasoline arson in the kitchen, which have not been reported so far, were conducted and compared. Next, the observation of fire damage using the accumulated heat-flux was evaluated by a newly developed analysis tool for visual evaluation. The simulation results such as burning behavior, temperature changes, and the burned away phenomenon of the door showed good agreement with those experimental results. Burning behavior in the kitchen, that couldn't be observed in the combustion experiment were grasped in detail in the simulation. Furthermore, the relationship between the fire source and the fire damage on the floor, which couldn't be explained only by the observation results after extinguishing the fire, could be reasonably explained by the visual evaluation of burning behavior and the accumulated heat-flux in the kitchen by using the simulation. Therefore, the fire simulation was shown to be an effective tool for analyzing fire phenomena.

With the increase in the recording density of hard disk drives, the narrower magnetic pole and read-sensor widths in writing and reading heads are required, and techniques used for the magnetic behavior analysis in a nanoscale area is essential. The observation of the in-plane domain structure of the writer pole for a perpendicular recording (PMR) head was performed by electron holography in order to elucidate the mechanism of the pole erasure originating from the instability of the magnetic domain state. The results revealed that the stability of the domain structure is strongly related to the domain wall trapping, and the pole erasure can be suppressed by realizing the stable domain structures. With respect to a current perpendicular to plane (CPP)-giant magneto-resistive (GMR) head, which has been promising candidates of a next-generation reading head element, the insertion of non-magnetic materials, such as Cu, between the ferromagnetic pinned and free layers is known to increase the MR ratio. For realizing the practical use of the CPP-GMR head, effects of the insertion of materials on the increase in the MR ratio were investigated by X-ray magnetic circular dichroism (XMCD). The results revealed that XMCD is a powerful technique to obtain information on electronic states and magnetic moments with the help of the theoretical electronic band calculation. The potential application of secondary cantilever resonance magnetic force microscopy and spin-polarized scanning electron microscope to the in-situ magnetic imaging of PMR heads will be also discussed.
