Strengths of Exaggerated Tsunami-Originated Placenames : Disaster Subculture in Sanriku Coast, Japan

Disaster-originated placename is a kind of disaster subculture that is used for a practical purpose of identifying a location while reminding the past disaster experience. They are expected to transmit the risks and knowledge of high-risk low-frequency natural hazards, surviving over time and generations. This paper compares the perceptions to tsunami-originated placenames in local communities having realistic and exaggerated origins in Sanriku Coast, Japan. The reality of tsunami-originated placenames is first assessed by comparing the tsunami run-ups indicated in the origins and that of the tsunami in the Great East Japan Earthquake 2011 using GIS and digital elevation model. Considerable proportions of placenames had exaggerated origins, but the group interviews to local communities revealed that origins indicating unrealistic tsunami run-ups were more believed than that of the more realistic ones. We discuss that accurate hazard information will be discredited if it contradicts to the people’s everyday life and the desire for safety, and even imprecise and ambiguous information can survive if it is embedded to a system of local knowledge that consistently explains the various facts in a local area that requires explanation

Effects of life events and stress on neutrophil functions in elderly men

Abstract Background Psychological stress or life events might significantly decrease neutrophil function in elderly individuals and lead to infectious diseases. However, relationships between these factors have not been examined in detail. We investigated the relationships between neutrophil function measured using the nitroblue tetrazolium (NBT) reduction test and measurements of psychological stress and life events among 81 men aged over 60 years. Results The numbers and scores for life events were significantly higher (p  Conclusions Chronic psychological stress due to life events decreases neutrophil functions among elderly men.</p

土佐湾及び四国沖黒潮流域で採集されたウナギ目魚類レプトケファルス幼生の分布

土佐湾及び四隅沖黒潮流域で、1990年1月にウナギ目魚類レプトケファルス幼生の採集を行った。採集は丸稚ネット(口径1.3m、網口面積1.33㎡、目合O.33mm)による傾斜曳あるいはステップ曳と高速稚魚ネット(網口面積2.03㎡、目合2.0mm)による表層曳で行われた。計41尾のレプトケファルス幼生が黒潮流域で採れた。その内訳はギンアナゴGnathophis nystromi nystromi(JORDAN et SNYDER)(33尾)、ニラミアナゴ属sp. 5 Ariesoma sp. 5(1尾)、ニラミアナゴ属sp. 7 Ariosoma sp. 7(2尾)、クロアナゴConger japonicus BLEEKER(1尾)、クロアナゴ亜科sp. 1 Congrinae sp. 1(2尾)、メクラアナゴDysomma anguillare BARNARD(2尾)であった。全個体の82.9%(34尾)が黒潮南外側域に分布していた。またギンアナゴは全個体が表層曳で、それ以外は全でステップ曳(ワイヤー長;500, 400, 300, 200, 100m)で採集された。A total of 41 leptocephali was collected in the Kuroshio waters off Shikoku Island. They included 33 Gnathophis nystromi nystromi (JORDAN et SNYDER), one Ariosoma sp. 5, two Ariosoma sp. 7, one Conger japonicus BLEEKER, two Congrinae sp. 1, and two Dysomma anguillare BARNARD. Most of leptocephali collected (82.9% of a total catch) were occurred in the southern boundary of the Kuroshio Current. All the Gnathophis leptocephali were collected with the surface horizontal tow of High Speed Larva Net, and the other leptocephali were with step tow of Larva Net
