JOURNAL FREE ACCESSPhysicochemical and rheological properties were studied in order to elucidate the difference of starches obtained from 14 kinds of non-glutinous rice.
Amylose contents were from 16 to 23% by the measurement of iodine method. Starches of low amylose content were somewhat more adhesive and cohesive in texturometric measurement than those of high amylose varieties. X-Ray diffractometer curve of these samples showed A-spectrum and there was no difference among samples.
Starches obtained from rice of high preference on sensory test showed higher viscosity than those of less paratable rice. The gelatinization temperature by amylography was found to be significantly correlated to the sensory evaluation of cooked rice.View full abstractDownload PDF (945K) -

JOURNAL FREE ACCESSThis study was designed to test the effect of cow-bone-powder on skeletal metabolism of rat model of postmenopausal osteoporosis.
SD-strain female rats weighing about 100 g were ovariectomized and fed on a low calcium diet (0.003% Ca, 0.3% P) for 22 days. The rats were then divided into two groups, CaCO3 diet fed rats and cow-bone-powder diet (containing 0.3% calcium and 0.3% phosphorus) fed rats for 27 days.
Compared with the rats fed with CaCO3 diet, the rats fed with the cow-bone-powder diet showed a significant increase in 1) the calcium content of the femur, 2) the breaking-force of the femur, 3) the number and activity of bone trabecula mass.
The cow-bone-powder may be more suitable as a source of dietary calcium for the skeletal metabolism of postmenopausal osteoporosis than CaCO3.View full abstractDownload PDF (1052K) -

JOURNAL FREE ACCESSExperimental study by a constant stress rheometer on creep compliance and viscosity at 20°C and 30°C has been carried out on the juices of three kinds of Dioscorea opposita Thunb., namely Tsukune-, Icho- and Naga-imo after the treatment with a mixer and a grater.
These samples could be represented as a mechanical model of six elements with a Voigt unit after analysis of the creep compliance data. The samples prepared by mixer treatment were showed as two Voigt units in series at 30°C. The Newtonian viscosities (ηN) seemed to be dependent on mean shear rate during creep measurements.
The viscosity of the sample increased with rest time in general, however, Tsukune- and Nagaimo under the same condition such as in treatment, temperature and rest time showed the highest and the lowest respectively.
Weak correlation existed between the retardation viscosity (η1) and the viscosity coefficient (μ), but no correlation existed between ηN and μ.View full abstractDownload PDF (756K) -

JOURNAL FREE ACCESSBehavior of water in gelatinized glutinous rice starch, nonglutinous rice starch and nonglutinous rice in course of retrogradation at 3°C was studied by pulsed NMR measuring spin relaxation times of water molecules. Changes of T1 and T2, and hence, changes of the correlation time (τb) and the fraction of bound water (P) in retrogradation process of nonglutinous rice starch and rice were both small and closely similar in each other. On the contrary, remarkable change of water behavior was observed in retrogradation process of gelatinized glutinous rice starch. The most remarkable changes observed around the water content of 1 g/DM g, were as follows; P increased from 0.1 to 0.23 and τb from 5 × 10-8 to 12 × 10-8 sec at 3 days after gelatinization. In cases of more or less water content than 1 g/DM g, the changes of P and τb in retrogradation were smaller. As water content was decreased, changes of P and τb occurred fast, namely, on the first day and little change was observed thereafter. Retrogradation proceeded gradually as the water content become larger, and finally no change of P and τb was observable for samples containing larger water content than 3 g/DM g.View full abstractDownload PDF (807K) -

JOURNAL FREE ACCESSA main purpose of winter coats is to keep body warm, whose performance is related to the thermal resistance of their clothing materials. The coefficient of equivalent overall heat transmission, Kr, is measured and studied in relation to compressional properties for five kinds of material groups (fur, imitation fur, packing fabric, woven fabric, and leather). The material group of larger thickness generally results in smaller value of Kr, i.e., larger thermal resistance. However, samples in each group, especially in fur, shows rather a great scatter from the average trend. Closer relations are found between Kr and other compressional properties, and the relevant property depends on the kind of material because of great difference in the structure.View full abstractDownload PDF (1142K) -

JOURNAL FREE ACCESSTo analyze the variation of body proportion in relation to stature, the allometry equation was applied to somatometric data concerning the garment design, which were obtained from 4, 278 males and 4, 123 females aged 25 to 69 years, measured in 1971-1972.
The following results were obtained.
1) Three girth measurements (bust girth, waist girth, hip girth) were judged inappropriate for application of the allometry method, because their correlation coefficients with stature were very low or insignificant.
2) In cases of other three measurements (lower limb length, posterior arm length, posterior shoulder length), all but one of allometry were uniphasic, while the posterior arm length in females, diphasic.
3) All the three measurements showed positive allometry in both sexes. The sex differences of the values α were insignificant for the majority of the cases. The value α in lower limb length was larger than that in posterior arm length irrespective of sex.View full abstractDownload PDF (689K) -

JOURNAL FREE ACCESSA survey on use of time was conducted, mainly to confirm the relationship between household work and age, on 221 subjects (61 males and 160 females) ranging in age from sixties to nineties living together with their children in and around Kumamoto City.
A significant decrease in the total amount of household working time was observed in the senile group over 75 years old. The decrease was most remarkable in household tasks using hands and arms. Periods of household work and rest showed a negative correlation : an increase in the duration of household working time was achieved at the cost of rest time, resulting in a net increase in the total working time.
Current mechanization enabled the senior people to perform daily household tasks more easily by themselves. Such physical exercises seem to give proper stimuli to peripheral nerves and results in checking the progress of aging.View full abstractDownload PDF (899K) -

JOURNAL FREE ACCESSPrincipal component analysis was applied to 23 food expenditure in 49 cities. To begin with, 6 principal components were extracted and characterized. Then, an individual principal component score for each city was calculated, and graded in 5 ranks. The main results were as follows :
1. The first principal component could be regarded as a regional characteristic factor, the second as a modernized dietary life factor, the third as a dietary life service purchase factor, the fourth as an Americanized factor, the fifth as condiments, dry vegetables and seaweeds factor and the sixth as a traditional luxury factor.
2. In the first factor, the top three cities were Akita, Aomori and Toyama; in the second, they were Nara, Wakayama and Osaka; in the third, Gifu, Kyoto and Shizuoka; in the fourth, Naha, Tottori and Urawa; in the fifth, Matsue, Fukuoka and Toyama; in the sixth, Sendai, Kawasaki and Chiba. On the other hand, the bottom three cities in the first factor were Miyazaki, Naha and Kagoshima; in the second, Nagano, Maehashi and Niigata; in the third, Akita, Aomori and Naha; in the fourth, Nagasaki, Shizuoka and Kochi; in the fifth, Kochi, Sapporo and Kofu; and in the sixth, Toyama, Tottori and Fukui.View full abstractDownload PDF (1529K) -
