Resettlement to their radiation-contaminated hometown could be an option for people displaced at the time of a nuclear disaster; however, little information is available on the safety implications of these resettlement programs. Kawauchi village, located 12-30 km southwest of the Fukushima Daiichi nuclear power plant, was one of the 11 municipalities where… (More)
BACKGROUND The Fukushima Dai-ichi nuclear disaster, the first level-7 major nuclear disaster since Chernobyl, raised concerns about the future health consequences of exposure to and intake of radionuclides. Factors determining the risk and level of internal radiation contamination after a nuclear accident, which are a key to understanding and improving… (More)
BACKGROUND Safety of evacuation is of paramount importance in disaster planning for elderly people; however, little effort has been made to investigate evacuation-related mortality risks. After the Fukushima Daiichi Nuclear Plant accident we conducted a retrospective cohort survival survey of elderly evacuees. METHODS A total of 715 residents admitted to… (More)
Perspectives On 11 March 2011, the great earthquake in eastern Japan and its accompanying tsunami caused a meltdown at the Dai-ichi nuclear power plant in Fukushima. Large amounts of airborne radioactive materials were released into the atmosphere, causing widespread environmental contamination throughout eastern Japan with potentially damaging long-term… (More)
BACKGROUND The Fukushima Daiichi nuclear disaster caused a global panic by a release of harmful radionuclides. In a disaster setting, misusage of contemporary media sources available today can lead to disseminated incorrect information and panic. The study aims to build a scale which examines associations between media and individual anxieties, and to… (More)
We formulate multiple-view geometry for omni-directional and panorama-camera systems. The mathematical formulations enable us to derive the geometrical and algebraic constraints for multiple panorama-camera configurations. The constraints permit us to reconstruct three-dimensional objects for a large feasible region.
To generate drought-tolerant sugarcane, we obtained hybrid lines by the intergeneric hybridization of a Saccharum spp. hybrid with Erianthus arundinaceus. A test using 5S rDNA as a marker identified five intergeneric hybrid lines with a production efficiency of approximately 3 %. There was difficulty in maintaining these hybrid lines because they were weak,… (More)
