Features of a continuing group and a dropping out group observed from the results of group medical examinations over a period of 15 yearsTetsuo TOKUDA1993 Volume 29 Issue 1 Pages 1-10

JOURNAL FREE ACCESSThree hundred and eighty-three persons of the seventy-year-olds of different sexes were selected. They underwent four times of group medical examinations at an interval of five years. A secular change of physique and strength of a “continuing group” persons who attended every occasion of the group medical examination, and a “dropping out group” persons who were absent from some of the occasions, was analyzed. The method of analysis was mainly focus on the features of the continuing group by taking those of the dropping out group into consideration.
Persons who underwent every occasion of the group medical examination, i.e. four times, accounted for only 16% of the examinees who had attended the first occasion of the medical examination. Although declines in the physique and strength due to aging were observed, but the pace of the declining did not progress uniformly. The tendency of contraction of stature with the advance of age became dull, the tendency of losing weight became intense and one-foot balance time with eyes open had a tendency to reduce by half every five years. Daily vitality, grip strength and one-foot balance time with eyes open of the continuing group were higher than those of the dropping out group, and the rates of declining in stature, weight and grip strength per five years of the continuing group remained at low levels.View full abstractDownload PDF (4830K) -

JOURNAL FREE ACCESSThe figures are perceived and preferred in different ways depending upon the interaction between the human aspects and the objects for which the figures are used. This study investigated how the visual impression and preference of the figures were affected by the major of the university students and their sensation seeking tendency. Literature course students, science and engineering course students, and art course students were asked to rate the visual impression for nine figures divided horizontally and vertically by orthogonal lines, and to take Sensation Seeking Scale. The principal component analysis and the cluster analysis of the data indicated that the art course students more preferred the figures in which division intervals strikingly changed from narrow to wide than the students of the other courses did, and that the higher sensation seekers tended to prefer the dynamic and complex figures more than the lower sensation seekers did.View full abstractDownload PDF (2736K) -

JOURNAL FREE ACCESSIn this study, the test method was developed for measuring perceptional abilities of colors, characters and figures. Subjects were twenty-five patients with cerebral palsy who were classified into disabled class 1 or 2 on the one hand, spastic or athetoic type on the other. It was found that the function indexes with upper limbs movement differed significantly between two disabled classes and between two paralytic types. The disabled class 2 showed higher scores than those of the class 1, and the spastic type higher scores than the athetoic type. Further it turned out that perceptional abilities were in close correlation with ADL (Activities of Daily Living). Perception time was examined without the upper limbs movement. There were significant differences in perception time between the two paralytic types and the disabled class 1 manifested a longer time. However no marked difference was recognized between the paralytic types.View full abstractDownload PDF (2605K) -

JOURNAL FREE ACCESSThis paper examines napping effects on arousal level in a night duty taken by hospital nurses. Nine healthy unmarried hospital nurses had participated in this experimental field study. They were subjected to both “nap condition” and “no-nap condition”. They took nap from 2:30 to 4:00 (a formal nap period in the hospital) under nap condition. Under no-nap condition, they chatted with an experimenter in that period. Measurements during awakening had carried out 90min. intervel from 23:30 to 10:00. The measures are CFF (Critical Flicker Fusion Frequency), 4 SRT (4 Selective Reaction Time), SFF (Subjective Fatigue Feelings) and KSS (Kwansei-Gakuin Sleepiness Scale: it was modified Stanford Sleepiness Scale for Japanese). During sleep periods, polygram was measured by ambulatory monitoring system. The results are that they slept for 59.6min. during napping period. Its sleep structure occupaied stage 2 (31.8min.), and little consisted of SWS and REMS. However, under nap and no-nap condition, there was signiicant difference between in CFF, 10% faster 4 SRT and SFF (factor of sleepiness and dullness" and “difficulty in concentration”) after 5:30. It was suggested that a small amount of SWS and REMS in a sleep structure of a nocturnal nap has an effect of improving arousal level during a night duty.View full abstractDownload PDF (2605K) -

JOURNAL FREE ACCESSThis paper examined napping effects on subsequent sleeps in a night duty taken by hospital nurses. Six healthy unmarried hospital nurses had participated in this experimental field study. They were subjected to both “nap condition (slept from 2:30 to 4:00)” and “no-nap condition (chatted with an experimenter for that period)”. During sleep periods, polygram was measured by ambulatory monitoring system. The results were that they slept for 59.7min. and showed short sleep latency and high sleep efficiency during napping period. But its sleep structure occupaied stage 2 and little consisted of SWS and REMS. For daytime sleep, hours of each sleep variables under no-nap condition showed long tendency compared with those under nap condition. These hours in daytime sleep under no-nap condition were nearly the same as those in nocturnal nap plus daytime sleep under nap condition. In nocturnal sleep in the next day taken after night duty, there were more intermittent awaking time and stage 1 sleep under no-nap condition. However these results showed hardly significant differences both conditions. It was considered that “prophylactic nap” taken in the evening before working night duty effected on subsequent sleeps.View full abstractDownload PDF (2916K)
