A Srudy on the Changes of the Performance Space in Awa-Dance

阿波踊りのパフォーマンス空間は、利用される公共空間や運営管理、仮設の装置、踊り集団によって一丁廻り期、桟敷及び審査場・競演場期、演舞場期、演舞場・街角踊り期の4つに分けることができる。一丁廻り期、その踊り範囲は、藩政期は町民地、明治期以降は市内全体へと広がった。踊り集団は地域に帰属するコミュニティで形成され、地域の街路や空地で踊った。桟敷及び審査場・競演場期は、阿波踊りが観光化し、踊り手・見手の関係をつくる仮設の装置を作った。このことによって、踊りに「見せる」・「見る」の意識がうまれた。演舞場期は運営組織や管理体制が統一され、さらに阿波踊り全体の規模や個々のパフォーマンス空間を大きくすることができた。また公園や道路整備が進んだことによって、道路以外のパフォーマンス空間も多くつくられた

Duodenal mucosal hemodynamics in patients with liver cirrhosis.

Clinical studies show that patients with liver cirrhosis associated with portal hypertension have a high incidence of duodenal ulcer and duodenitis. However, little information is available concerning pathophysiological process of such duodenal diseases in liver cirrhosis. Hemodynamics of the duodenal mucosa was studied in cirrhotics with esophageal varices (68 cases) and in noncirrhotics with non-ulcer dyspepsia (37 cases) as well. In each group, hemoglobin concentration in the peripheral venous blood was measured, and mucosal hemodynamics was examined in 4 regions of the duodenum by endoscopic reflectance spectrophotometer. No significant intergroup difference was noted in the mean age or sex ratio. Hemoglobin concentration in the peripheral venous blood was significantly lower (p less than 0.01) in the cirrhotics. There were no significant intergroup differences in duodenal mucosal blood volume. However, the cirrhotics showed significantly lower oxygen saturation of hemoglobin in all regions of the duodenum (p less than 0.01). These results show that the cirrhotics with esophageal varices had relative increase in blood volume and decrease in oxygen saturation of hemoglobin in the duodenal mucosa. Such microcirculatory disturbances seem to predispose liver cirrhosis patients to duodenal injury.</p
