The author exemplifies the framework of PSI (Pervasive System for Indoor-GIS) for exploring the spatial model of dynamic human behavior and developing various services in an ubiquitous computational environment. This does not mean merely constructing a software framework; rather, it means attempting to establish an inclusive service framework for ubiquitous computing. The most advantageous aspect of this component-oriented framework is that it contributes toward developing various service applications for ubiquitous computation as the occasion demands. That is, service applications are expected to do modeling, simulation, monitoring, Web services, and other applications. The author also discusses the relative issues on making a coordinating bridge between behavioral sciences and multiagent systems.
To date, our global society is endlessly threatened by disasters. This article devotes to describe both risks and crises on disaster, and especially it deals with the nature of Fukushima case caused by accident of nuclear power plant (aftermath of the disaster at 11th Mar. 2011). Since the human history, this case was one of extreme disasters and multiplied tragedies damaged by quakes, tsunamis, and nuclear power plant accidents. Still now, it presents a number of challenges indeed to be overcome. One of the hardest problems from the inventory of the Fukushima case was characterized as intensive purifications of nuclear pollutions around Fukushima and collective migration of evacuees caused by both natural and human-made disasters. And ongoing disputes against safety seem to vary widely such as compensations, socioeconomic reasons, environmental restorations, and community reconstructions. The author intends to review these issues and discuss future design for the lessons from the disaster.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
