JOURNAL FREE ACCESSIn the present investigation, a geometrical description of the range of motion (ROM) of lower limb multiple joints including the effects of biarticular muscles was developed. The ROM illustration was also represented mathematically in the matrix formulation indicating separately the ROM due to monoarticular and biarticular muscles. This systematic and quantitative method involves all the conventional clinical ROM measurements and is able to be applied even to patients with severe joint contracture. Photographic analysis was used to measure lower limb joint angles in patients with spastic cerebral palsy (SCP) and normal subjects, then, their ROM was assessed by the geometrical method. The SCP patients showed greater reduction in the ROM of the joints presumably due to the joint soft tissue contracture and the shortening of both monoarticular and biarticular muscles. The symptoms seem to result from their disused joint mobility as well as the intrinsic spasticity. From the results, the necessity and usefulness of the geometrical method were also determined.View full abstractDownload PDF (2709K) -

JOURNAL FREE ACCESSIn this study, avoidance areas, based on avoidance locus in human passing behavior, were investigated by two experiments. In order to examine general characteristics of passing behavior, an experiment on a road was conducted. In the experiment, passing behaviors were recorded using a VTR. The passing behavior was classified into three types based on its path. The most typical type observed in the first experiment was as follows: The subject returned to the original locus he had before starting avoidance motion, after the subject had finished passing. In order to analyze and identify avoidance areas of this type, an experiment in a laboratory was conducted. In this experiment, the subjects passed an experimenter who stood, walked, and ran with short steps. Subjects' motion paths under these conditions were analyzed and the following two characteristics were found: (1) locus agreed well with the catenary, and (2) walking velocity was constant in passing. Avoidance areas were calculated using these characteristics. Results indicated that an avoidance area of an experimenter standing was similar to that of an experimenter walking.View full abstractDownload PDF (920K) -
(Part. 3) Relation between the difference of body figure and clothing pattern —The upper body—Haruko MAKABE, Miyuki BEPPU1999 Volume 35 Issue 1 Pages 17-24

JOURNAL FREE ACCESSThis paper is based on results of the principal component analysis on the upper body. The purpose of this is to investigate the validity of clothing patterns classified by physical type. In order to confirm the fit of the neck-base to shoulder, nine waist patterns were drawn, and sewn into the experimental clothes. The subjects were 262 young adult women from 20 to 21 years of age.
The shoulder slope type clothes were found to fit 143 persons. Each different type of clothing fit on the corresponding body type of the subjects. The physical type clothes fit on all subjects. Body measurements are essential for the experimental clothing in order to support the measurements of the feature figure. Based on body size and figure, comfortable and good-fitting clothing can be made.View full abstractDownload PDF (7383K) -

JOURNAL FREE ACCESSThis paper investigated the effect of the lighting factors on the atmospheric evaluation of the texture of the interior material. In a full-sized model living room with diffusional lighting from its ceiling, an experiment was conducted under three illuminance conditions (65lx, 200 lx and 650lx), each of two lighting-color conditions (Daywhite color and Incandescent color). The results showed that the evaluation was constituted by four factors, ‹Evaluation›, ‹Potency›, ‹Appearance›, and ‹Modern-ness›. ‹Evaluation› and ‹Modern-ness› were affected by illuminance, ‹Potency› was affected by lighting-color, and ‹Appearance› was affected by both lighting-color and illuminance. Also there was a tendency for rough and dense surface to be strongly affected by the lighting conditions. The reason for this was thought to be that the appearance of the surface was varied with illuminance, and so the evaluation was affected by this change of appearance. Also, it was considered that the evaluation of softness was affected by lighting-color in the same way as warmth.View full abstractDownload PDF (3104K) -

JOURNAL FREE ACCESSThis paper examines the effects on mental fatigue of changes in the intensity of physical activity. An ergometer-equipped bicycle was used to attain three levels of physical activity: 20% below AT (where no muscular fatigue occurs), AT, and 20% above AT (where muscular fatigue occurs). As an indicator of mental fatigue, scores obtained in addition tests administered before and one hour after physical activity at each intensity level were used. The results of these tests showed that mental fatigue decreased after physical activity at 20% below AT, increased after physical activity at AT, and underwent no change after physical activity at 20% above AT, where AT is the level below which long periods of activity can be sustained. These results demonstrate that physical activity at a level easily sustained for a long period of time can lower mental fatigue, suggesting that the intensity of physical activity must be selected carefully.View full abstractDownload PDF (772K) -

JOURNAL FREE ACCESSInfluence of food temperature on oral stereognosis and preference were examined in healthy university students. Stereognosis between a column and an ellipse-shaped pillar, between a cube and a rectangular solid for boiled fishpaste and bean curd were compared among temperatures of 10°C, 36°C and 60°C, using triangle test. The rating scale tests were performed to determine the hedonic tone for the materials with different temperatures.
In ellipse-shaped pillar for boiled fishpaste, discriminative ability at 36°C were superior to those at 10°C and 60°C. In ellipse-shaped pillar and rectangular solid for bean curd, discriminative ability at 36°C were superior to that at 60°C.
While there was no difference in preference among temperatures for boiled fish-paste, preference values at 10°C and 60°C were higher than that at 36°C for bean curd.
These results suggest that oral stereognosis of food is different among temperatures, and that its stereognosis does not correlate with preference.View full abstractDownload PDF (2246K) -
