Exposure to ultraviolet radiation (UVR) occurs from both natural and artificial sources. The main natural source is the sun. On the other hand, artificial UVR sources are widely used in industry and also used in hospitals, Iaboratories, etc. because of their germicidal properties. They are even used for cosmetic purposes. UVR can be classified into three regions according to its wavelength : as UVA (320-400nm), UVB (320-280nm) and UVC (280-200nm). The UVC has the greatest health effect on humans among the three. The sun radiates a wide range of spectrum of electromagnetic radiation including the UVR, however the radiation below 290 nm in wavelength does hot reach the surface of the earth for effective absorption by the strato-spheric ozone layer. As a result, UVR from a natural source consists of only UVA and a part of UVB. On the other hand, artificial UVR sources include UVC region and have serious effects on the human body, especially on the skin and eyes.

Utilizing an ultrasonic device (B-mode, 7.5MHz), the thickness of subcutaneous fat was measured at 54 different points in the bodies of 59 males (aged 20-25) and 66 females (aged 20-23). The results were as follows;1. The females had significantly thicker subcutaneous fat than those of the males at every point measured.2. The thick subcutaneous fats were obsereved at the abdomen, buttocks, and the anterior and medial parts of the thigh in the males, and at the breast, buttocks, abdomen, the posterior, medial, and anterior parts of the thigh, and the anterior, medial, and posterior parts of the upperarm in the females, respectively.3. The subcutaneous fat of both sexes was more likely to be thicker in body parts closer to the trunk than the extremities.4. The correlation coefficient between the percent body fat and the mean thickness of subcutaneous fat obtained from data was 0.91 for the males and 0.83 for the females.

The present study was desigend to examine the effects of illuminance and color tempera-ture of room lighting. Four male students volunteered as subjects. Each of them performed a calculation task for 95 minutes under nine different lighting environments consisting of a combination of three levels of illuminance (320lx, 1000lx and 2000lx) and three levels of color temperature (3000°K, 5000°K and 7500°K). Three types of fluorescent lamps were used as a light source to vary the color temperature. Blood pr.essure, critical flicker frequency (CFF) and accommodation time of eye movements were measured every 30 minutes during the task. The accommodation time was significantly influenced by the illuminance level and both the relaxation time and contraction time were prolonged under 2000lx. The diastolic blood pressure was significantly affected by the color temperature level and increased under 7500°K. As for the CFF, the interaction between illuminance and color temperature was significant. These results mean that not only the illuminance but also color temperature produces physio-logical effects. The present study may be the first to recognize the effect of color temperature on the blood pressure

Blood lactate level begins to increase at a certain work load or oxygen consumption which is called as anaerobic threshold (AT). However, numerous studies showed that anaerobic glycolysis is not the cause of the enhanced accumulation of blood lactate during exercise. Increased lactate production is seen even in fully aerobic muscles. Some studies suggest that elevation of lactate is due to a temporary imbalance between the rates of pyruvate formation by aerobic glycolysis and pyruvate utilization in the Krebs cycle. These results clearly suggest

To elucidate the mechanisms of adaptation to a low-energy and low-protein vegan diet, we carried out dietary surveys and nitrogen balance studies five times during one year on two women and a man who ate raw brown rice, raw green vegetables, three kinds of raw roots, fruit and salt daily. Individual subjects modified this vegan diet slightly. The mean daily energy intake of the subjects was 18, 14, and 32 kcallkg, of body weight. The loss of body weight was about 10% of the initial level. The daily nitrogen balance was -32, -33, and 1lmg N/kg of body weight. In spite of the negative nitrogen balance, the results of routine clinical tests, initially normal, did not change with the vegan diet. Ten months after the start of the vegan diet, the subjects were given 15N urea orally. The incorporation of 15N into serum proteins suggested that these subjects could utilize urea nitrogen for body protein synthesis. The level of 15N in serum proteins was close to the level in other normal adult men on a low-protein diet with adequate energy for 2 weeks.

The purpose of the present study was to examine hemispheric differences in visual recogni-tion of two kanji letters. Kanji phrases and nonsense kanji letters were presented unilaterally to the left or right visual hemifield in thirty normal right-handed men by a tachistoscope. The experiments were separated into three conditions ; the mixing task (ten phrases and ten sets of nonsense letters are presented by mixture), the phrase task (twenty phrases are presented), and the nonsense letters task (twenty sets of nonsense letters are presented). Under all conditions, significant right visual hemifield superiorities for the accuracy of recognition of phrase and nonsense letters were observed.
