In Japan, Quarter-million crossing collisions at intersections accounted for one-fourth of the total accidents in 2005. Three-fourths of collisions took place at urban intersections, more than half of them occurred at uncontrolled intersections. Risks of crossing collisions depend on the quality of visual environment at intersection. This study aimed to assess the legibility and effectiveness of 23 traffic convex mirrors installed at 10 urban intersections, after the road management authority inspected and repaired. The legibility of mirror was assessed by means of the photographs of each mirror taken from the drivers’ viewpoint at a legal stop line, entering from the lower priority direction. “Three ergonomics requirements” suggested by the authors were used as the criteria of legibility assessment; (1) Position of road lane, (2) Blind area and (3) Road surface markings. Combining these 3 criteria, the comprehensive assessment of mirror was indicated in 2-grade scale, such as “Good” or “Poor”, namely so dangerous to be improved. A field assessment revealed that 11 among 23 mirrors were still improperly installed. However, simulation analysis showed that 7 among 11 poor mirrors could be improved by adjusting the angle of mirror plate or displacing mirror plate/poles. In conclusion, the present official guideline in regard with installing mirror should be revised to add newly “three ergonomics requirements” for preventive safety. Application of these new guidelines in practice, a typical low-cost and low technology-oriented improvement to reduce crossing collisions, was highly recommended.

4개월령 때의 예방접종을 위한 진찰에서 수축기잡음이 청취되었던 1세령의 암컷, 체중 3㎏의 치와와가 각종의 검사에서 중증의 판막상성(瓣上性)-판막성(瓣性)폐동맥협착증으로 진단되었다. 이 증례에 대하여 표면냉각단순저체온마취(表面冷却單純低體溫麻醉)에의한 심장박동 정지하(停止下)에서의 심장막 패치법(Patch method)으로 외과수술을 실시하여 교정에 성공하였다. 수술 후에는 X선 검사에 의하여 심흉격비율(心胸隔比)의 축소와 우심실압(右心室壓)의 저하가 인정되었다. In a one-year-old female Chihuahua, weighing 3㎏, which had shown a systolic murmur at the examination of vaccination at 4 months of age, we diagnosed several supravalvular and valvular pulmonic stenoses using various examinations. Our surgical treatment with the pericardial path-method under cardiac arrest succeeded using simple surface hypothermia. The treatment induced a reduction of the cardiothoracic ratio in radiographic examination and decline of right ventricle pressure after operation.
