JOURNAL FREE ACCESSThis paper introduces a new method which estimates the performance of workers on the work production, using the work achievement and the tendency equation which are derived from the mean of the data observed.
This method is an analytical method using a kind of ratio method. That is, the results of work are estimated by a work achievement Q which is a function of the ratio of variation δ, where δ is the dispersion of the data.
As an example of practical applications this paper shows the performance of individual press workers.View full abstractDownload PDF (1883K) -

JOURNAL FREE ACCESSThe Kata thermometer was invented as a man-thermal model by L. Hill in 1916. Nowadays, the thermometer is said to be available for measuring low air movement such as we find in an ordinary room in everyday life.
In the present study, the formula for calculating air movement is discussed and the experiments on the heat transfer coefficient of the Kata are made. As a result of the investigations and the experiments, it is proved that the existing Kata calcuating formula of air movement can not be applied to an ordinary thermal environment where the ambient air temperature is not equal to the radiant and that the value of Kata's convective heat transfer coefficient is considerably larger than that obtained from the present laboratory work in a controlled test-chamber. Further, an approach for a rational measurement of air movement by using the dry and the wet Kata thermometers at the same time is proposed. It is possible to obtain the correct value of air movement by the present method, regardless of whether the air temperature is equal to the radiant or not.View full abstractDownload PDF (2223K) -
Development of the improved thermal dolorimetersIchiro FUKUMOTO1982 Volume 18 Issue 6 Pages 325-331

JOURNAL FREE ACCESSThe thermal dolorimeter by Hardy has been used to measure thermal pain threshold. The original model is accurate but has following drawbacks. Measurements must be repeated to arrive at the thermal pain threshold. It is too large in size and requires elaborate preparations for the subjects in field works.
A new thermal dolorimeter is constructed improving those drawbacks. In order to avoid repetition in measurement we adopt period of heating until tolerable temperature as the thermal pain threshold, keeping the stimulating energy fixed. In order to reduce size and to make more convenient, a small lamp is used to heat subject by thermal conduction. The results were satisfactory. The time for measurement is drastically decreased enabling the instrument to follow fast changing phenomena.
As applications of the improved thermal dolorimeter, thermal pain thresholds were measured under following conditions.
(1) Patients are treated by electrical pain abater.
(2) Measurement for a month to know relationship to ambient temperature.
(3) Subjects are under physical exercises such as swimming, running and bathing.
(4) Measueament to know the relationship of threshold to circadian rhythm.
(5) Subjects are under visual biofeedback.
(6) Computer simulation to estimate the depth of heat sensor in human body.
(7) Application to Oriental medicine to find the location of acute point for moxibustion.
The results of measurement were compared to the data of Hardy's instrument. The accuracy of our model is almost the same as Hardy's to be 5% in one subject and 18% between different subjects.View full abstractDownload PDF (798K) -
