In view of the rapid large scale development of underground in the central big cities, especially around terminal stations, evacuation experiments have been conducted with 79 subjects using an underground shopping mall near Tokyo Station actually in service after business hours. Four groups of 20 subjects started from different locations and time to “escape” from any of emergency exits was measured for each subject. 12 out of the 79 subjects wore elderly simulator to compare evacuation behavior of elderly and that of younger people. The evacuation behavior was also monitored by video cameras and escape route of each subject was reproduced afterwards. Five experiments were conducted using the lighting conditions and layout of emergency exits as parameters. The starting point was changed from experiment to experiment, not making any subject repeat similar selection of escape route. The shopping mall is composed of grid of passages, and is installed with escape route sign lights on every passage according to Fire Service Law. In every experiment, it was observed that considerable portion of subjects did not select right passage toward nearest exit at intersection nor passed over right exits. These are not compliant with widely accepted assumption for deterministic modeling of evacuation in mall-like facility. Factors dictating the probability to select right passage at intersections and that to recognize emergency exit are analyzed from the experimental data.

【目的】心肺運動負荷試験(CPX)のAT レベルの心拍数(THRAT)での運動処方が困難な場合はKarvonen の式から得られる心拍数(THRkarvonen)を参考に実施するが, 心不全やβ遮断薬投与例では必ずしも適切な決定ができない.本研究はβ遮断薬投与中の急性心筋梗塞患者を対象にATHRとKarvonen 式の関係を検討し,適切な心拍数を求めることを目的とした.【方法】対象はβ遮断薬投与中の急性心筋梗塞患者20 例,年齢62.7±8.2 歳.a(220-年齢)を最大HR とし,係数a は実際にCPX で得られた実測最大HR からa =実測最大HR/(220-年齢)を求め,また,Karvonen の式から運動強度の係数k =(THRAT-安静時HR)/(最大HR-安静時HR)として求め,係数k と臨床的指標の関係について検討した.【結果】CPX から求めた係数a は0.72±0.09,係数k は0.42±0.13,THRmodified Karvonen = 0.42[0.72(220-年齢)-安静時HR]+安静時HR で,THRAT とTHRmodifiedKarvonen の相関関係はr=0.84(p < 0.01)であった.係数k と臨床的指標の関係は心リハ開始日数とLVEF に関連性が認められTHRclinical =(0.005×LVEF-0.015×心リハ開始まで+0.312)[0.72(220-年齢)-安静時HR]+安静時HR とすると,THRAT との相関関係はr=0.88(p < 0.01)であった.【結語】β遮断薬投与中の急性心筋梗塞患者はTHRmodified Karvonen = 0.42[0.72(220-年齢)-安静時HR]+安静時HR で求められ,係数k はLVEF と心リハ開始日数と関連して変化する可能性が示された.

A series of on-site experiments are conducted on the upward evacuation by escalator of groups of 50 subjects including 12 simulated aged people. Two escalators, 49.5m long and 22m tall one, and 12.3m long and 5.7m tall one with parallel stairs in a large convention facility in downtown Tokyo, were used. The experiments revealed the following.1. Upward walking velocity on a still escalator, 0.78-0.79m/s for normal subjects, is nearly identical with that on normal stairs.2. Upward walking velocity on an escalator running at 0.50m/s is reduced by 5-10% from that on a still escalator.3. Upward walking velocity is virtually independent from the distance from the entrance within the range of 22m in height for normal and simulated aged pedestrians in spite of the height and length of each step significantly larger than those of stairs.4. Effective flow coefficient at the entrance is around 1.15 persons/ms for a still escalator and 1.78p/ms for a one running at 0.50m/s.5. The effective flow coefficient at the entrance of an escalator is reduced by the increase of the escalator length for the local congestions generally seen in long escalators.
