JOURNAL FREE ACCESSThe actual measurement of the body surface area generally take much trouble. And the existance of some interrelation among the height, weight and the others now lead to the calculation of the body surface area using a way of multipling these factors by a constant coefficient. After much investigation about a variety of calculation formula which have desingned by now we reached a conculusion that a from A=K1X+K2Y+Q (Howland-Dana from) is more desirable than the others, above all by applying X for the height (H .... cm) and Y for the weight (W .... g) the most desirable approximation can be got. From this point of view we achieved a new calculation formula for Japanease adult man and woman as follows. A=0.0901W+62.49H+266 for man and A=0.1309W+ 37.33H + 1799 for woman come as the result.View full abstractDownload PDF (535K) -

JOURNAL FREE ACCESSWe have fixed the new calculation formula of surface area of Japans over 12 years of age as follows
A=0.1342W+51.48H-375 (A=cm2W=g H=cm)
This formula have the least error both in mean and variance than Takahira's and formula, which is most widely in our country, and Nagasaki Univ. formula.View full abstractDownload PDF (943K) -

JOURNAL FREE ACCESSIn the studies of physical motion analysis the multiple photographic method with a stroboscope or the fast motion picture which has been used, are not sufficient to pursue a motion of some kinds of sports and of some hidden physical spot only from one direction and difficult to synchronize picture obtaind from three direction.
To make use of electrical engineering from the points of Physiology and Kinesiology, it is worthy of pursuing a physical motion on three dimensions, up & down, right & left and before & behind at once, and furthermore, physiological phenomena in electrocardiogram and electromyogram with connection to the above analyzer.
For that purpose a physical locomotion pursuit analyzer (SN-type, refered to PLPA later on) was devised.
The present devised analyzer is composed of a three dimensions-accelerometor in a gyroscope, a preamplifier, a integration amplifier and a pen-writing recorder.
As already known in the principle of physics, velocity can be obtained by single integration of acceleration rate and displacement by double integration of a acceleration rate.
In above the PLPA, therefore, acceleration rate, velocity and displacement, each of three dimensions can be determined. Capacity of the present analyzer was as follows; Frequency rate : 1.5-20.0 HZ (Static accelerated component under 1.5 HZ was cut by differentiation circuit of DC-cut), time constant of electrical integration circuit : about 0.2sec.
In the present report the outline of PLPA and some data of our experiments obtained by use of it were dealt.
The problems of the telemetering system of this analyzer and digital exhibition by connection to computer require further study.View full abstractDownload PDF (1135K) -

JOURNAL FREE ACCESSIn order to find the useful carpet in human life, physiological and morphological changes in the young women who standed and walked for 30-120 min on the three kinds of ones were studied.
As physiological changes before and after standing or walking on the each carpet, the flicker value, the volume change and the skin temperature of leg, the body swaying, the O2 consumption, the lactate formation and the blood sugar were measured. As morphological test, x-ray photograph of the foot ankle was obtained and it was examined on the stand point of Orthopedics.
In summary, it was found that the experimental results obtained on the middle soft carpet showed the most reasonable for daily life.View full abstractDownload PDF (2674K) -
