It has been said that lower legs are the parts where 70% women in their 20's notice swelling. In this study, subjects were eight women around 20 years old. An examination has been carried out for the relation among the volume changes in lower legs and feet using the measuring boot made by our own selves, and outside air temperature / room temperature on awakening / basal body temperature / girths of a trunk and lower legs I body weight measured on the same day. The volume of lower legs and feet were measured after 4-hour wearing of normal knee-high socks. At first, an examination has been performed for the volume of lower legs and feet in a specific subject. The volume of both legs increased significantly in the afternoon compared with that of the morning. A right leg increased its volume than a left leg did. Also, the volume of right lower leg and foot in the afternoon (2614.4 +/- 298.0 mL) significantly increased by 65.6 mL (α≤0.01) compared with that in the morning (2548.9 +/- 269.1 mL) for all subjects (of 20.4 +/- 1.4 in BMI) . In the sitting position, the difference in volume of the lower leg and foot obtained by subtracting the volume in the morning from that in the afternoon was 45.2 mL. By contrast, in the standing position, the above difference was 79.7 mL. Thus a significant difference, 34.5 mL is found (α≤ 0.05) between the standing and sitting positions. It was clear that lower legs and feet were hard to get swelled if we spent in sitting position. From the reason why all subjects were right-footedness and the volume changes in the left leg has a positive correlation with that in the right leg, so the left volume of lower legs and feet of all subjects changed as the same as the right. The examination of the regularity of the swelling mentioned above has shown that the significantly positive correlation was found among volume changes of right leg and foot / outside air temperature / room temperature on awakening / basal body temperature / body weight / the volume of the left lower leg and foot, if attention is paid to two weeks before and after the menstrual start day. It seemed that the simple relations were concluded. The more outside air temperature was high, the more the room temperature on awakening was high. The more the room temperature on awakening was high, the more the body weight and the volume of both legs increased.

Recently, a lot of compressive knee-high socks for beauty shape in legs are marketed. A person minding swelling is apt to choose a product having high pressure to make a leg and foot look slender. However, no effect has been clarified of compressive knee-high socks on the aim for the beauty shape and on the action of the living body. In this study, we examined the basic design of comfortable and effective knee-high socks to compensate swelling. Using the measuring boot developed by our own selves, we measured the volume of a leg and foot, twice a day, keeping a measuring interval more than four hours. We examined the clothing pressure, its pressure feeling (evaluated by a ratio scale), and relative volume changes (the relative value that subtracted the volume in the morning from that in the afternoon) when we wore three kinds of knee-high socks which consist of socks A (with most comfortable fit), socks B (the compressive knee-high socks with the lowest pressure on the market), and socks C (socks A covered with a shin supporter over the calf) . In the foot, the clothing pressure of socks B was significantly higher than that of socks A and C. The subjects reported socks B as “tight”, even if no difference was recognized in relative volume rate of change among three kinds of socks. And, even if we compressed only a lower leg without compressing foot (by wearing socks C), we obtained the same compressive effect of a lower lei as that of a foot (bv wearing socks B) .

To develop a new experimental teaching material for improving the sanitary consciousness, the number of bacteria colonies cultured on shirts and blouses were measured by using the food stamp method. A comparison has been made between the number of colonies in collars, sleeves, abdomens, and back of the shirts and that of the blouses respectively. The significant differences were observed between the number of colonies on the collars and the sleeves, and between that on the collar and the back of male and female students. The number of colonies on the collar of the female students was higher than that of the male students, and that of the back of the male students was higher than that of the female students.
For all of both male and female students, the number of colonies on the sleeve was positively correlated with that on the abdomen and the back. Many colonies have been found on the collar, the abdomen, and the back of the students who didn't put on underwear in the winter.
