A 29-years old woman, who had a history of mental retardation and abnormal habit of eating tissue papers, was admitted to our hospital because of abdominal pain and vomiting. Abdominal X-ray and CT scan demonstrated much intestinal gas, and a colonoscopy revealed obstruction caused with tissue papers and large ulcers in the sigmoid colon. Therefore, we removed the tissue papers endoscopically using a grasper. After endoscopic treatment, her symptoms were immediately improved and a few longitudinal ulcer scars were seen, three month later. The endoscopic extraction was safe and effective in the colonic obstruction with tissue papers.

In this paper, we proposed a simple urban model including individuals' travel behavior and residential choice behavior. Multi-agent simulation framework is described. We performed several experiments to evaluate political measures which will solve problems about motorization. As a result, drastic mobility management scheme increased the number of travelers using a train, and the distribution of residences became compact. However, it also increased many agents' total costs of living because of high rent and several kinds of cost including time cost and fatigue cost to reach a station. On the other hand, raising gas price made CO2 emission less and kept total cost of living lower than the drastic mobility management measure. This suggests that to have people use train or bus by changing their attitude might be socially more expensive than to make people chose whether they use car or not under the condition that gas price is raised.

本研究では、ガボールフィルタを用いて各々の波の方向のエッジを検出し、スケール、回転変化にも対応した、ジェスチャ識別の為の指を精度よく捉える特徴点自動抽出の提案をする。提案手法では、対象となる画像から背景差分により手領域を抽出しガボールフィルタを用いて手が画像上に持つ方向性の情報を画像として抽出する。また各々のフィルタリングされた画像を局所的に比較することで指先に特化した特徴点の抽出を試みる。
