The purpose of this study is to clarify the characteristics of Home Economics by the method of citation analysis of the Journal of Home Economics of Japan for about 40 years from Vol. 1, No. 1 (1951) to Vol. 40, No. 12 (1989).
The results are as follows :
(1) The secular change of the number of the cited literature, the form of the cited literature, and the proportion of citation from J. Home Econ. Jpn. to all citations are as same as Okamoto et al.'s results (J. Home Econ. Jpn., 38, 1117 (1987)).
(2) J. Home Econ. Jpn. is the main cited journal.^* The variety of cited literature increases gradually and citations concentrate to some major journals, * that is J. Home Econ. Jpn., J. Agric. Chem. Soc. Jpn., J. Jpn. Soc. Nutr. Food Sci., and so on.
(3) The proportion of foreign literature to all cited literature is low. Home Economics may have a character of independence or isolation internationally.
(4) As to the proportion of journal ^* citation to all citations, Home Economics is equal to arts and near to engineering or technology. Home Economics has a character of applied science.
(5) As to the proportion of citation from J. Home Econ. Jpn. to journal^* citations, Home Economics may have a character of autonomy or self-dependence.
(^*The concept of these “journal” used in this study will be explained in exactly detail in the text.)

In order to understand the present state or condition of Home Economics, the author analyzed original papers from the Journal of Home Economics of Japan over a 40 year time span from Vol. 1, No. 1 (1951) to Vol. 40, No. 12 (1989).
The results are as follows :
(1) The yearly number of original papers increases gradually. On the other hand, the number of original papers in an issue decreases.
(2) The proportion of the number of original papers on the topic of food science and clothing and textiles-related science to all the number of original papers is 80.7%. Throughout about 40 years the number of papers in food science has consistently increased, but the number of papers in clothing and textiles-related science has decreased recently.
(3) The proportion of the number of original papers using experimental methods to all original papers is 78.3%.
(4) Many figures are used in natural science studies, and many tables are used in social science studies. In humanities studies, figures and tables are not used much.
(5) The number of figures and tables, space of results and discussion, and space of summary were made to indexes and were plotted on a three dimensional figure, which makes it clear more discrepancy both food science and clothing and textiles-related science existed than in other fields. If the quantity of the new knowledges is related to these dimensions, therefore both food science and clothing and textiles-related science contribute much to Home Economics.

The purpose of this study is to explore gaps between attitudes toward gender roles of male and female students, by using such criteria as attitudes toward role relationships between male and female, the double standard of sexual morals, men's leadership in dating, and energy allocation to occupation and homemaking after marriage. The survey was conducted in January, 1990 to 735 university students in Tokyo and its outskirts. The major findings are as follows :
(1) ISRO (The Index of Sex-Role Orientation, E.A. Dreyer et al.) scores on attitudes toward role relationships between male and female point out that 45% of the female students are innovative type, but about the half of the male students are traditional one.
(2) Compared with female students, male students tend to accept the double standard of sexual morals.
(3) Female students expect that males play leadership roles when they go out together more than male students themselves intend to.
(4) Male students wish to allocate less energy to occupation than their fathers do, and female students hope to allocate less energy to homemaking than their mothers. As a result, the present tendency to give too much attachment to occupation for males and homemaking for females will be relieved in their married life.

Flavor compounds of boiled radish odor and changes of 4-methylthio-3-butenyl isothiocyanate (MTBeI) that has an irritating odor were studied. Flavor condensates of boiled radish prepared by shaking with ether and SDE method were analyzed with GC and GC-MS. The flavor of boiled radish showed strong hydrogen sulfide-like odors from the low boiling compounds and the desirable, boiled radish-like odor. The main flavor constituents were the same with those of the fresh radish odor.
It was thought that MTBeI was almost decomposed into the volatile CH₃SH, CH₃SSCH₃ and, in part, formed non-volatile compound (colour) and methylthiobuthyl isothiocyanate (MTBI) which was the main constituents of the boiled radish (78%). It was assumed that the decomposition of MTBeI and the remaining of MTBI or the change of MTBeI to MTBI were necessary for the formation of the boiled radish odor.

The heat-induced gelatinization of collagen and the solubilization, of myofibrillar proteins in meat during the preparation of soup stock were investigated. The ratio of gelatin originating from collagen to the total soluble protein in soup stock was about 30% after heating for 6 hr. When the purified myofibrillar proteins were heated, most disappeared from the SDS-polyacrylamide gel electrophoretic pattern, and 40, 000-, 23, 000- and 10, 000-18, 000-dalton proteins appeared. The molecular weights of these proteins were similar to those of the proteins in soup stock. Furthermore, the content of heat-soluble protein from myofibrils increased gradually with incteasing heating time.
The content of soluble proteins was lower when a mixture of sarcoplasmic and myofibrillar proteins was heated than when they were heated individually. A mixture with a higher ratio of sarcoplasmic proteins to myofibrillar proteins gave a more intense protein band of 10, 000-18, 000 daltons by SDS-polyacrylamide gel electrophoresis, the content of this low molecular weight protein increasing with increasing heating time.
These results suggest that some proteins in soup stock originate from not only stroma proteins, but also from sarcoplasmic and myofibrillar proteins.

This study was taken to know the way of living and the evaluation of the access-type on the public housing with terrace. This public housing with terrace was designed as the house plan suitable for the subtropical zone. The terrace was expected to plan an important role of giving shade and of making a court yard. This public housing was built at Setouchi town, Kagoshima Prefecture in 1980. The housing unit plan was divided into two kinds by the access-type. One is the improved type of the north door access, the other is the south terrace type.
The questionnaire survey was carried out in July in 1990. The results of survey are as follows :
(1) The evaluation of the quality for the terrace, the staircase, and the access-type.
(2) The differences of the way of living and the use of the rooms under each access-type.
