The purpose of the present case study was to clarify calligraphic skill of a Japanese calligrapher quantitatively. For this purpose, the brushwork of an expert calligrapher was kinematically compared with that of a novice as well as an intermediate. Three subjects (an expert calligrapher, an intermediate, and a novice) participated in the experiment. A motion capture system was used to capture the motion of a brush during writing a kanji on a Japanese writing paper. As results, absolute writing speed tended to fasten and the variability of the vertical displacement of a brush decreased along with the calligraphic skill. The frequency analysis of the horizontal velocity of a brush revealed that a dominant region shifted toward a low-frequency direction in the expert in comparison with the intermediate although their absolute writing speeds were not significantly different. These results suggest that the expert calligrapher could move the brush with rather slow than rapid change of velocity on the horizontal plane accompanying with lowering the vertical brush displacement.

Educational and research activity of physical education teaching staffs in Daito Bunka University were assessed by Corporation of the University Physical Education (Japan). Data for assessment were obtained from reports published in The Bulletin of Daito Bunka University and other published reports by Daito Bunka University. Physical education teaching staffs in Daito Bunka University were highly evaluated and awarded a prize of model for promoted faculty development in physical education. The performance of physical education teaching staffs were well improved by establishment of the Department of Sports and health sciences at Daito Bunka University in 2005.

The authors reported 7 cases that showed development of new aneurysms or enlargement of small aneurysms originally less than 3mm in diameter. New aneurysms of the anterior communicating artery and the right pericallosal artery were found in one case. In this patient with a 5 year history of hypertensiovn, cerebral angiography performed 8 years before following a head trauma had revealed marked arteriosclerosis and a hypoplasia of A1_1, but no aneurysm. Development of an aneurysm from a dilatation at the origin of the right embryonal posterior cerebral artery was found 3 years after the clipping of an aneurysm of the left internal carotid artery in the other case. In 3 cases, a small unruptured aneurysm all originally less than 3mm in diameter previously noted in conjunction with a ruptured aneurysm were found to have enlarged 3 to 13 years after the clipping of the ruptured aneurysm. In these 3 cases, anomalies of the circle of Willis, such as hypoplasia of unilateral A_1, infundibular dilatation at the origin of the posterior communicating artery and the embryonal posterior cerebral artery were revealed. Arteriosclerosis and hypertension were noted in 2 cases. In 2 cases, a small ruptured aneurysm, which had not been recognized at the first subarachnoid hemorrhage, was noted to have enlarged 5 and10 years after the first bleeding. Changes of the arterial wall due to hypertension, arteriosclerosis, etc., and hemodynamic stress caused by anomalies of the circle of Willis seemed to be responsible for the new development of aneurysm and the enlargernent of aneurysm. A small aneurysm less than 3mm in diameter, including an unruptured aneurysm that is found in association with the ruptured aneurysm, have a high incidence of progressive enlargement and rupture. Therefore, even a small aneurysm should be diagnosed and treated precisely.
