A multilingual disaster information system (MLDI) has been developed to overcome the language barrier during times of natural disaster. MLDI is a web-based system that includes templates in nine languages so that translated texts can be made available immediately. Mobile phone e-mail with graphic text is a useful tool for delivering multilingual disaster(More)
A 26-year-old man was referred to our hospital with vomiting and high fever. He was disoriented and laboratory results showed microangiopathic hemolytic anemia (Hb 7.1 g/dl) and severe thrombocytopenia (15 x 10(3)/microl). The diagnosis of thrombotic thrombocytopenic purpura (TTP) was established. The activity of von Willebrand cleaving protease (ADAMTS13)(More)
BACKGROUND Prophylactic use of anticoagulants for septic patients in intensive care unit is a standard therapy for the prevention of venous thrombosis. Moreover, recent studies have demonstrated the anti-inflammatory effects of anticoagulants such as Factor Xa inhibitors and heparins. However, there have been no studies to examine the effects of(More)
BACKGROUND Direct hemoperfusion with a polymyxin B-immobilized column (PMX-DHP) is recognized to be effective for the treatment of septic shock and is widely applied in Japan. However, it is still unknown whether the efficacy is limited to cardiovascular dysfunction. Therefore, the purpose of this study was to examine the effects of PMX-DHP on a(More)
We developed a method to analyze sketch maps by GIS, and applied it to an actual case study. We found that analysis using buffer operation was more effective for sketch map analyses than other methods, such as the entire road length method and area method. After modeling the buffer method, an experimental study of the micro-genetic cognitive process was(More)
A man aged in his 60′s was admitted to Kobe Rosai Hospital, Kobe, Japan, because of impaired consciousness. One week before admission, he manifested erythema on his trunk and extremities that was associated neither with fever nor with flulike symptoms. Thirst and nausea developed within a few days of erythema onset. Whereas the erythema disappeared(More)
We examined the effects of predator-prey distance (PPD) and trajectory of the predator on the body patterns that the pharaoh cuttlefish, Sepia pharaonis, shows in response to a predator. A model predator moving in three different trajectories was presented to the cuttlefish: T1, approached the cuttlefish but bypassed above; T2, approached directly toward(More)
Mesoporous titania-silica composite films with highly aligned cylindrical pores are prepared by the sol-gel method using a substrate with structural anisotropy. The strong alignment effect of a rubbing-treated polyimide film on a substrate provides a narrow alignment distribution in the plane of the film regardless of the fast condensation rate of titania(More)
