In order to study a swelling process of beans, we measured volume and weight of seven kinds of beans using a hand-made volumenometer reported in the previous paper.
As the results, it became clear that both weight and volume of beans were saturated after swelling for 8 hours, and weight of beans increased by two times that of its original, and volume showed a value 2-3 times as much.
We estimated change of net volume, net weight and normalized density of each beans according to 24 hours' swelling, and discussed the swelling mechanism of beans.

After a mixture of egg white lysozyme and methyl linoleate in aqueous system was irradiated with UV, lysozyme was polymerized during incubation at 40°C. Molecular sizes of the polymers were not affected by a reducing agent, dithiothreitol. The blockage of amino groups by succinylation prevented the polymerization of lysozyme. The cleavage of disulfide bonds by carboxy-methylation of sulfhydryl groups changed the conformation of lysozyme and promoted the polymerization. These results indicated that not disulfide bonds but amino groups of lysine residues contribute to the polymerization of lysozyme. It was also suggested that the conformational change of lysozyme affects the polymerization.

The effects of methanol extracts from beni-koji produced by Monascus pilosus (MP) or Monascus ankar (MA) and pigments (MAP) produced by MA on blood pressure, lipid metabolism and cation balance of male spontaneously hypertensive rats (SHR) fed a 1% NaCl diet for 17 days were examined. The results were as follows.
1) The blood pressure of control group markedly elevated, while the blood pressure of group fed diets added extract equivalent to 0.3% and 0.03% MP or MA koji-moldes depressed significantly at 10th and 15th feeding day, respectively. On the contrary, MAP could not exhibit any hypotensive effects.
2) Plasma Na/K ratio of groups fed MP- or MA-diet decreased during the test period. Positive correlation between blood pressure and Na/K ratio was observed. There are no significant difference in mineral balance of cations tested so far.
3) Increase of fecal excretion of Na, K, Ca, Mg, Cu and Fe was observed in the group fed 1% but not 0.1% MAP-diet.
4) The plasma total cholesterol levels of groups fed MP-, MA- and MAP-diet were lower than that of control group on both 7th and 15th day.

An inquiry of the taste preference was made for infants ranging from 3 to 6 years of age (120 males and 88 females) and their parents (208 males and 208 females) in order to find the tendency of the preference toward sweet, sour, salty and bitter tastes. Thresholds of gustatory sensitivity toward sweet, sour and salty taste were measured by using aqueous solutions of sucrose, citric acid. and sodium chloride, respectively. Patterns and correlations of the taste preference were explicated by using Hayashi's Quantification Method. The pattern of the taste preference of the infants was different from that of their parents and a little difference between infant males and females was observed. Infants had a tendency to prefer sweet foods such as chocolate, short cake and ice cream, especially female infants sour foods such as natsumikan. There were high correlations between infants and their parents upon preferring salty and bitter foods such as shiokara and celery. Gustatory thresholds of infants were lower than those of 20-years-old females. Infants had perceived 0.20.8% concentration of sucrose, 0.0290.06% concentration of citric acid and 0.044.16% concentration of sodium chloride. Difference of the infants' expression was recognized for aqueous solutions of three tastes.

In order to understand quantitatively the loss phenomena in the width of sewn fabrics, the relations between the loss in the width of sewn fabrics and each of the thickness of threads, the thickness of fabrics and the seam finishes were investigated by using various man-made leathers and polyester threads of different thickness.
(1) In the relation between the thickness of the thread and the loss in the width of the sewn fabric, the thicker the thread, the larger the loss.
(2) The loss in the width of the sewn fabric of welt seam is larger than that of open seam.
(3) The thicker the fabric, the larger the loss in the width of the sewn fabric. Furthermore, there are high correlations between the thickness of fabrics and the loss in the width of sewn fabrics.
(4) In the schematic models of the loss in the width of sewn fabrics, the theoretical loss in the width of the sewn fabric D can be approximately expressed as,
D=(π-2)t+πα or D=πt+πα
where t is the thickness of fabric, α is the swelling in the area of the seam and is associated with the thickness of thread and the stitch density. As above mentioned, from the experimental and theoretical view points, it is made clear that the loss phenomena in the width of sewn fabrics is related to the fabric thickness, the thickness of the thread, the stitch density and the method of seam finishes.

In the previous report, we have measured images of 304 dress samples which were selected from photographs in fashion magazines for young ladies and factor-analyzed the data. The purposes of this paper were (1) to classify dress samples according to the factor scores by cluster analysis, (2) to clarify the difference in the features of the design among the classified dress types, and (3) to find the effective scales to distinguish these dress types by quantification theory II. The results are summarized as follows :
(1) These dress samples were classified into four types; (1) career elegance type, (2) elegance feminine type, (3) basic casual type, and (4) trendy casual ty pe.
(2) The significant relationship between the dress types and the design-elements were found in 27 items within 43 items.
(3) The most effective scale to distinguish the four types was elegance-casual. The degree of the distinguishment was dependent on the dresses. The features of the design made it possible to discriminate two dress types selected from the four dress types clearly.

Based on the data obtained in the first report (Part 1), we have categorized the stability of the residential life of the elderly persons which is observed in the change of their residential relationship with their families for the past 16 years (1970-1986). The changes seen in their working conditions, situations of employment and the changes of residential relationship due to their selection of residential place, have been analyzed and the characteristic points we have found are as follows.
1) The residential relationship of the elderly persons with their families has been changed due to the selection of their residential place on the occasion of their childrens marriage and finding employment, etc., and there by formed a variety of residential lives such as those of stable, quasi-stable, quasi-unstable and unstable types.
2) Characterizing the residential life of the elderly persons, 67 families are of stable type (60.4% of the sample) and 44 families of unstable type (39.6% of the sample).
3) Considering of tenure of residence, in the families which don't live in their own residence, stable type is 1.7%, other types are 15.4%. Therefore, the stability of residential life relates considerally with tenure of residence.
4) 86 elderly persons are having no occupations and 85 are considered to be supported financially by their children, where one person has no children to be supported by 67 persons are belonging to the category of the future stable type of the residential relationship and will be supported closely by their children.
5) There are many issues to be solved for the families with elderly persons of a variety of residential relationship, particularly from the viewpoints of their residential life, medical care and welfare. In addition to their own efforts, regional care and administration should play bigger and various roles in taking measures to meet with these new situations.
