We aim at designing an effective evacuation support system for disaster response, specifically tailored to aid the walking wounded, a significant group of victims suffering from relatively minor injuries. Supplying walking wounded victims with a simple navigation aid enables them to arrive at a predetermined safe area, while allowing first responders to be allocated where they are most needed. ...

Almost all terrestrial plants produce green leaf volatiles (GLVs), consisting of six-carbon (C6) aldehydes, alcohols and their esters, after mechanical wounding. C6 aldehydes deter enemies, but C6 alcohols and esters are rather inert. In this study, we address why the ability to produce various GLVs in wounded plant tissues has been conserved in the plant kingdom. The major product in completel...

The IPO (ipomoelin) gene was isolated from sweet potato (Ipomoea batatas cv Tainung 57) and used as a molecular probe to investigate its regulation by hydrogen peroxide (H(2)O(2)) and nitric oxide (NO) after sweet potato was wounded. The expression of the IPO gene was stimulated by H(2)O(2) whether or not the plant was wounded, but its expression after wounding was totally suppressed by the pre...
