JOURNAL FREE ACCESSWater heated in 600 W microwave oven vaporized at the rate of 10-12 g/min with definite periodicity. The period expressed in terms of water height was found to be 8 mm regardless of beaker diameter. On the basis of this value, a standing wave may possibly be produced during heating in microwave oven, because the value is in agreement with a wavelength of standing wave of 2, 450 MHz in a dielectric medium of ε=60.
With an increase in starch content (0-40%) and heating time, the evaporation rate decreased. in the case of conventional heating, owing to development of a dense starch-rich-layer on the surface of the mixture. In contrast, the evaporation rate of water in a microwave oven was fast and almost independent of starch content, since the dielectric loss of gelatinized starch was exceeded that of water.
The hardness of starch-water mixtures tested by Tensilon was the same following conventional and microwave heating, so far as the same water content was concerned.View full abstractDownload PDF (792K) -

JOURNAL FREE ACCESSThe relationship between food liking characteristics and food liking factors was studied for 211 villagers of Osato, Saitama Prefecture, using Hayashi's Quantification Method III and data obtained from the results of a survey on their food liking and from health examination data.
1) Eigenvalues given by the analysis using the food liking for 33 ordinary foods as variables showed that the response patterns to food liking can be categorized with common factors.
2) The first and the second axes indicated the food liking category and the food items, respectively, and when cooking methods and food groups were similar, food liking tended to be alike.
3) The food liking characteristic for Western dishes and their raw materials such as meats and dairy products was closely associated with such factors as the 20 to 40 age group, high T-ch value, TG value and preference for less salty taste.
4) The food liking characteristic for Japanese dishes such as salted vegetables, Miso soup, noodles and Sake was closely associated with such factors as the 50 to 60 age group, high blood pressure, smoking habits and preference for a salty taste.View full abstractDownload PDF (1021K) -
Assessment of Moisture-Transporting Performance of Disposable Diapers (Part 1)Kyoko KAI, Makiyo SAITA, Sonoe HIRAMATSU1987 Volume 38 Issue 3 Pages 191-197

JOURNAL FREE ACCESSNon-transporting disposable diapers (ND), moisture-transporting disposable diapers (MD), and diapers covered by wool flannel (WC) were tested for their moisture-transporting performance by cup method test and wearing test.
Wearing test : Under ordinary clothes, the samples were worn for 2 hr. Humidities inside diapers (H) were measured at the front and the back in sitting and lying postures. The samples were weighed before and after the test to obtain weight change (W).
The result is as follows :
1) The moisture transport ratios of water proof materials was 25 % for WC. 20 % for MD-sheet, and 0 % for ND-sheet. The difference between WC and MD wasn't significantly recognized.
2) In general the inside humidities at wearing of above diapers were increased in order to ND >MD >WC. The difference between WC and MD was significantly recognized.
3) The correlation between final H and W was : γ=0.79 (30 ± 1°C, 60 +5 % R.H.).View full abstractDownload PDF (948K) -
Methods for Analyzing Pressure on the Shoulder by the OvercoatHiroko YOSHIMURA, Toyoko SAKAI, Kinzo ISHIKAWA1987 Volume 38 Issue 3 Pages 199-203

JOURNAL FREE ACCESSWhen we put on a garment, we are aware of pressure on the shoulder. In this study, from the point of comfort and fitness, the pressure caused by weight of an overcoat is investigated.
Garment pressure (P) imposed on the body is stated by following equation,
P=Tv/γv+Th/γh+p,
where, T, tensile force; γ, radius of curvature on the body; and ρ, pressure by fabric weight (ρ). v means a direction in the vertical cross section and h is a direction parallel with the shoulder slope.
1) In the vertical cross section, downward force (Tv) at θ location is calculated as follows,
Tvθ=A·e-μθ+B.
A and B are variables that depend on ρ, μ (friction coefficient), γ and θ. Value of Tv rapidly drops as θ increases, and are balanced on the shoulder.
2) Th is regarded as tensile force which supports sleeve weight. It is measured with tension gauges at a point on the armhole.
3) Radius of curvature is the vertical cross section (γv) is the smallest at the vicinity of the top of the shoulder. On the other hand, radius of curvature (γh) is infinite, therefore, Th has no effect on garment pressure. As a result, the highest value of garment pressure is obtained near the top of the shoulder.View full abstractDownload PDF (517K) -

JOURNAL FREE ACCESSThe investigation of the seasonal (during summer and winter), menstrual (during menstruation period and non-menstruation period) and daily (during morning and afternoon) changes of lower leg surface areas and lower leg volumes of the women were performed.
1) The changes of lower leg surface areas were measured by using the Japanese paper replacement method. The subjects were 5 females aged from 21 to 24 years old.
The seasonal change of the lower leg surface areas was greater in the summer than in the winter, showing the mean difference of 16.5 cm2 from 5 subjects. The change of surface areas during the menstrual period was greater by 8.8 cm2 than during the non-menstrual period. The daily change of surface areas was greater by 10.0 cm2 in the afternoon than in the morning.
The seasonal, menstrual and daily changes of surface areas were greatest at the ankle among four parts of the lower leg.
2) The seasonal, menstrual and daily changes of the lower leg volumes were measured by using the water replacement method. The subjects were 5 females aged from 21 to 24 years old. The results of the volume change were the same as those of the surface area measurement. The portion where the individual differences appear most conspicuously was the ankle in both experiments.View full abstractDownload PDF (1445K) -
Multivariate Analysis on Body Measurement for Garments Planning in Boys and Girls (Part 4)Tomoko OMURA, Fusayo KAWAMURA, Naoko OSADA1987 Volume 38 Issue 3 Pages 213-219

JOURNAL FREE ACCESSCluster analysis was applied to five items which were obtained by the factor analysis of our previous report Part 3, after classifying 902 boys and 888 girls aged from 7 to 18 years into four aged groups.
The results were as follows :
1) It was found, by age and sex, that the classification into five clusters was most effective.
2) The body form was classified into ten patterns for girls, and nine patterns for boys.
3) For 28% of girls and 18% of boys, it is necessary to consider not only the size but also the silhouette of the body for classification of the body form.View full abstractDownload PDF (844K) -
A Basic Investigation on Scissors-Cutting in Homemaking Education (Part 3)Yoko TAKEI1987 Volume 38 Issue 3 Pages 221-230

Released on J-STAGE: March 10, 2010
JOURNAL FREE ACCESSExperiments of the straight-line cutting and curvilinear cutting with five kind of scissors and shears which have different mechanism were made on female elementary school pupils and female adults, and analysis of respiration curve and E.M.G. were made.
Practice investigation were also examined, and examination about scissors which was easy to use was done.
The results were as follows :
1) The same characteristic pattern was observed as reports, Parts 1 and 2 both in the respiration curve which was rhythmical and in the E.M.G. of which of discharge was small, the “experienced” who had used scissors and shears which were valued on easy to use.
2) The characteristic of scissors and shears which were easy to use were that the height of handle and position of screw was higher than touched line when people had it correctly, and that the swinging interval of screw position in cutting was short.
3) There was a coincidence between the evaluation of respiration curve and E.M.G. and that of practice investigation.View full abstractDownload PDF (1824K) -
