Daily observations for ambulance transports due to heat stroke from July to September in 2010 in Okayama prefecture, Japan were obtained from Fire and Disaster Management Agency in Japan. Data of meteorological parameters in Okayama prefecture, Japan were also obtained from Japan Meteorological Agency. Effect of meteorological parameters on ambulance transports due to heat stroke was analyzed. A total of 1133 ambulance transports due to heat stroke were observed in from July to September of 2010 in Okayama prefecture, Japan. Ambulance transports due to heat stroke was significantly correlated with air temperature. In addition, number of subjects with ambulance transports due to heat stroke over 34°C in the highest air temperature was 21.2 ± 9.8 per day. Higher air temperature was closely associated with higher ambulance transports due to heat stroke by using daily data in Okayama, prefecture, Japan.展开更多

Data of temperatures in Okayama (1891-2009), Tsuyama (1943-2009), Tokyo areas (1876-2009) and Hachijo Island (1907-2009) in Japan was obtained from Japan Meteorological Agency. Changes in temperatures in 4 areas in Japan were analyzed and compared. By using data from 1943 to 2009, some parameters of temperatures were significantly correlated with years. The change in parameters of temperatures in Hachijo Island was calmest among 4 areas. The changes in mean temperature in August and in a year in Okayama area for 50 years were the highest (August: 1.55?C, Year: 2.05?C) among 4 areas. In addition, correlation coefficient rate between years and the number of days over 35?C in August in Okayama area was highest (r = 0.407, p = 0.0037). Parameters of temperatures were gradually increased with years in Okayama area, especially in recent years. However, those associations were not clearly noted in Hachijo Island. In conclusion, global warming in Okayama might be accelerated more rapidly than that in Tokyo area in recent 50 years.展开更多

The Yoshii Group is composed of siliceous rocks and clastics, comprising chert-clastic sequences. The Yoshii Group is divided into four structural units （Units Ot 1, Ot 2, Ot 3, and Ot 4） in structurally ascending order. Lithological similarities and radiolarian age suggest that these units exhibit almost identical ocean plate stratigraphy. These units are structurally-repeated to form an imbricate structure. This structure was possibly formed by off-scrape accretion at a toe of an accretionary complex. Additionally, a review of previous studies indicates that an imbricate structure is common in the Akiyoshi terrane. The presence of an imbricate structure in the Akiyoshi terrane, Permian accretionary complex, indicates the possibility that a specific horizon of Permian pelagic sequences acted as a drcollement zone.展开更多
