-Preparation and Adaptation for the Separation by Death-Kumiko TAKAHASHI1989 Volume 40 Issue 7 Pages 575-585
Published: July 05, 1989
Released on J-STAGE: March 10, 2010
JOURNAL FREE ACCESSHusbands and wives who coped with, the crises of the independence of their children and the retirement, further in old age, have to confront more serious crisis that is the death of their spouses. The purpose of this study is to examine problems of the preparation and adaptation for the death of their spouses. The investigation was conducted to the widowed over 60. Among them, those who had been over 55 when their spouses had died, under 20 years after their spouse's death, and had children were selected. The samples were 174 males and 207 females.
The results are summarized as follows :
Nearly half of them did not talk with spouses on problems after the separation by death. Among changes of life after spouse's death, it is remarked that anxieties about their old age and the feeling of loneliness have been increasing. Man's feeling of loneliness is stronger than woman's one. After spouse's death, children play an important role as the object of emotional tie, but do not match spouse. However, the influence of spouse's death on the idea concerning living with a child is not so much. Thirty % of males and 40 % of females still want to live apart from children.View full abstractDownload PDF (2281K) -
On the Factors Affecting Variation of α-Amylase Activity in Saliva of Normal Subjects (Part 2)Nobuko TANAKA, Hirosi OKAMURA1989 Volume 40 Issue 7 Pages 587-592

JOURNAL FREE ACCESSThe effect of 3 kinds of tea solution (green tea, oolong and black tea) to human saliva α-amylase activity was examined.
Black tea specifically lowered the activity of a-amylase (89 % inhibition). Judging from such a result that the activity of α-amylase was not almost changed by the tannin free black tea extract prepared using the same black tea, it was cleared that tannin was a factor for lowering the activity of a-amylase.
The amounts of tannin in the extracts of 3 kinds of tea prepared from the same tea leaves were compared with each other but no difference was confirmed between green tea and black tea (0. 19, 0.21% respectively).
However, analysis of tannin component of tea solutions by thin layer chromatography revealed that black tea contained more amount of highly polymerized tannin than other teas did.
It was strongly suggested that this highly polymerized tannin is responsible for the inhibition of human salivary α-amylase.View full abstractDownload PDF (1560K) -
Kimiko OHTANI1989 Volume 40 Issue 7 Pages 593-601

JOURNAL FREE ACCESSThe relationship between cooking properties of different varieties of potato (Solanum tuberosum), Danshaku and Meikuiin, and their structure of non-starchy polysaccharides including cell wall polysaccharides was investigated.
Non-starchy polysaccharides were fractionated by successive extractions with water, hot water, 0.5 % ammonium oxalate, 5 % sodium hydroxide, 24 % potassium hydroxide and 90 % dimethyl sulfoxide.
When compared these two varieties of potato, the proportion of pectic substances, water-, hot water- and ammonium oxalate-soluble polysaccharides, showed higher in Danshaku and that of hemicellulosic substances, alkali-soluble polysaccharides, showed higher in Meikuiin.
The results of the structural investigation of water-soluble polysaccharide were reported.
Water-soluble polysaccharide from Meikuiin contained two kinds of α-1→6 glucan and that from Danshaku consisted of complicated structural polysaccharides, which have 5- linked-arabinose, 2-linked-rhamnose, 4-linked-galactose and 2, 6-linked-galactose residues.
Dextran-like polysaccharides obtained from Meikuiin can play an important role in preventing breakdown of potato tissues during cooking.View full abstractDownload PDF (1260K) -

JOURNAL FREE ACCESSAroma components of fresh Japanese radishes (Karami and Aokubi Daikon) were extracted with ether by shaking and analyzed by combined gas chromatography and mass spectrometry. Seventeen compounds, including 3 isothiocyanates, 5 methylthioisothiocyanates, 2 nitriles and 7 other compounds were identified. Main constituents were six compounds containing sulfur, which constituted more than 99 % of all aroma components of Karami Daikon.Among them, the most important compound was (E) -4-methylthio-3-butenyl isothiocyanate, which was contained about 62.7 mg% (627 ppm) in aroma condensate exacted from Karami Daikon. It has the irritating fresh radish odor at the concentration of 1.3 ppm. These results suggest that this compound contributes mainly to the characteristic odor of Karami Daikon, too.View full abstractDownload PDF (910K) -
The Shrinking Effects on the Drawing Force of Cloths along the Seam When Sewing by HandEiko ABE, Yasushi OMURA1989 Volume 40 Issue 7 Pages 609-617
Published: July 05, 1989
Released on J-STAGE: March 10, 2010
JOURNAL FREE ACCESSUsing a device made for a trial to record continuously the drawing force Fd, produced along a seam by worker's fingers, Fd diagrams were obtained. Analyzing these diagrams, the mechanical properties of cloths related to Fd were found. Then the differences of Fd between pre- and after-shrunk cloths were discussed. The results were obtained as follows :
In Fd, (1) the force constricting the interpenetrated sewing needle with the sewn cloths and (2) the force flattenning out crumpled cloths on the needle being held in the sewing-worker's right palm are concerned. (1) has some connections with dia. of sewing needle, stitch length, density of cloths, Young's modulus of cloths, and c with stitch length, bending rigidity and hysteresis of bending moment of cloths. High correlations between these factors and Fd were observed.
By the shrinking treatment, density, bending rigidity and hysteresis of bending moment of cloths decrease and Young's modulus of cloths increases. But, as the contribution of Young's modulus to Fd is smaller than those of other properties, Fd of shrunk cloths result smaller values than those of unshrunk ones, when the cloths sewn with the same stitch length using the same size of needle.View full abstractDownload PDF (1608K) -

JOURNAL FREE ACCESSIn order to investigate the fatigue of sewing threads in handsewing, the tenacity and elongation of the threads removed from seams was tested. And the surface of the threads was observed through an electron microscope.
The following results were obtained.
1) The tenacity, elongation and toughness of the threads after sewing varied with the distance from a needle eye.
2) The fatigue of the threads was widely varied depending on the kind of the threads.
3) The fatigue was related to the yarn-density and bending rigidity of the fabric.
4) The fatigue of the part of the threads touching a needle eye increased as the sewing progressed.
5) The observations through an electron microscope showed that the hairiness of the threads increased and that the structure of the threads was disarranged by sewing.View full abstractDownload PDF (1621K) -
