The purpose of this study were: (1) to determine buying practices of mothers concerning child-ren's shirts and slacks; (2) to find out the characteristics of satisfaction and dissatisfaction about these same two items of children's clothing; (3) to make gathered information available to consumers and manufacturers, and to suggest ways to improve children's clothing for consumers. The data for this study were collected through questionaires to 789 mothers of seven and eight years old children in three elementary schools from December 3 to December 14, 1978. The findings are as follows: 1. More than $71\%$ of mothers stated that all of their children's shirts and slacks were purchased ready-made. More than half of the children acquired some part of their clothing through hand-me-downs. 2. The store in which mothers purchased their children clothing most frequently was near-by market or wholesale market and the next was children's wear specialty shop. 3. Childrens accompanied mothers more frequently when slacks were being purchased than when shirts were. 4. More than half the children of seven and eight years old wear size 9$\~$10 and the next common size was size 11$\~$12. 5. Most mothers determined the proper size in clothing by having the child actually try on the clothing. 6. $44\%$ of mothers stated that they have a fitting problem with shirts and $64\%$ of mothers stated that they have fitting problems with slacks.

This study attempts to discern the purchasing pattern of urban husbands' clothing in Korea. Studies on this subject in other cultures show that wives play lesser role in purchasing activities of their husbands' clothing in the industrial societies rather than in the pre-industrial ones. It would be interesting to know the way selecting and buying husbands' clothing in urban Korea. Specifically questions to be answered include: Who makes the decision in selecting in kinds of husbands' clothing and who buy them? Data for this study has been collected through structured questionaire survey for 606 married women in the City of Seoul including 192 mothers of elementary school students, 58 elementary school teachers, 210 mothers of middle and high school students, 56 mothers of undergraduate students, and 47 college professors. Since most women of our sample are relatively high in educational level and working for various educational institutions, the findings of this study should not be generalized as a general trend of urban Korea. Major findings of this study include: 1) Purchasing husbands' clothing is not entirely wives' domain. The degree of participation on the part of wives in selecting and buying of their husbands' clothing depends upon the kinds of clothings. If it is for such items as underwear, socks, handkerchief, or umbrella, which are relatively easy to choose in terms of size, outlook, and price, more wives do the job. Other- wise, however, husbands more actively participate in selecting and buying their own clothings such as shoes, overcoats, neck tie, and formal wear. 2) In terms of clothing behavior of husbands, it seems to be a general trend that husbands select their clothings, but wives buy them. 3) Variables related to socio-economic status seem to affect the clothing behavior of husbands. Those who more actively participate in selecting and buying their clothings include: husbands whose wives have a job outside thier family, younger in age, middle school or high school graduates rather than college graduate or husbands with far lesser education, and husbands who live in western style houses rether than in traditional Korean houses.

To study possible modification of acrylic fiber, Cashmilon SF was treated with hexamethylene-diamine(HMDA) in toluene at elevated temperature. Physico-chemical properties of treated fiber were tested by dyeing with benzyl scarlet BS and by measuring tensile strength of the fiber. Following results were obtained from this experiment. 1) HMDA and fiber were condensed at above $120^{\circ}C$. 2) Treated samples could be dyed with acidic dyes. 3) Treatment with HMDA decreased tensile strength of the fiber. This study therefore suggests that HMDA can be used to modify the properties of the fiber.

The studies on shrinkage and characteristics of the weft knitted fabrics were investigated under the various dry and wet treating conditions. Various relaxation values were found out according to treating conditions. The characteristics of knitted fabrics such as shrinkage rate, thickness, spirality, elongation and recovery were also measured. The used knitting yams were OE (open-end) cotton and POY (pre-oriented yarn)-DTY (draw textured yam) polyester. The conclusions obtained in this study are as follows. 1. In case of dry relaxation little change of Ks values was seen with increasing time after 48 hours. So it was found that relaxation shrinkage of dry relaxation reached its maximal state in about 48 hours. 2. In case of wet relaxation, higher Ks values were observed, in comparision with those of dry one and higher shrinkage rates were also observed. But when experimental temperature was constant, sudden marked increases in Ks values and shrinkage rates appeared through the initial 4 hours, and after that time little change was seen in them. 3. As Ks value increases, thickness also increased. But thickness showed to some degree stability around Ks value 23. 4. As Ks value increases, spirality values also increased gradually. But little change of spirality values was observed above a certain Ks values (cotton 22.5, polyester 21.5). 5. As Ks value increases, the elongation decreased under a certain load, and the recovery was random.

Gan Tack is meetings for marriage in Royal Families only. There are three selection courses before the final decision of one person, and it done with a view to finding the best person in the country. On the history of costume, it was greatly changed in Yungjo's period. In this thesis, I studied the costumes of king Yungjo, Jungsungwanghu who is the consort of Yungjo, Inwonwanghu who is the consort of the late king, Sunhigung who is a seraglio of Yungjo, Ongjus who are King's daughters by seraglios, Sanggungs who are court ladies, Yumo who is a wet nurse, and etc., for Gan Tack with Hyaegyunggung-Hong who is chosen the consort of Prince, and research the Dresses, which are Jugori, Chima, Dangui, Gonryongpo, and Wonsam. The girls who attend Gan Tack dress up Jugori whose color is yellow, Chima whose color is red, and Dangui whose color is green. King wears in Gonryongpo, the Consorts in Wonsam, and the court ladies and Ongjus in Dangui, of course, there are differences of the colors and ornaments on the ranks. Finally, I hope this thesis will be of great help to the costume of historical dramas.

The effect of free fatty acid in fatty soil on the detergency of particulate soil was investigated. Cotton lawn fabric was soiled with the mixture of polmitic acid, hydrogenated fat, paraffin oil and iron oxide black altering the contents of palmitic acid and was laundered with different sur-fastants under various temperature and alkalinity. The rate of soil removal was estimated by means of the spectoometic analysis of iron on the fabric before and after washing. The results of dergency were compared those obtained by reflactance and K/S value from Kubelka-Munk equation which were derived from reflactance measurements.

Because of the scarcity of data, a study of costume during the Baikje period can be made imaginarily only with historical records as data. According to records, Baikje costume was almost the same as that of the Koguryo period. Consequently, we may well imagine Baikje costume by means of studying such materials as the mural paintings found in Koguryo tombs and the remains found in the royal tomb of Munyung. The basic form of costume of the Baikje period, therefore, might have been like this: Both male and female wore a kind of jacket(유: JEOGORI) and trousers(고: BAJI) with female-wearing skirt (상: CHIMA) thereon. Both men and women wore overcoat(포: DURUMAGI). They used to wear headdress(관모) and used leather shoes(화) Such a form of costume can be found in the costume of HANIWA(식륜) of Japan, which belonged to the costume of HOBOK (호복) of the northern area. Under the SHIMNEUK-PUM-KWAN-KE(십육품관계) system, that is, 16 grades of official ranks, officials of the Baikje dynasty wore clothes, coronets and belts, all of which differed from one another in colors, according to ranks. Such a system of Baikje might have influenced the KANI-JUNI-KAI (the 12-grade color discrimination of the coronet, 관위십이계) for the government officials of ancient Japan the Suiko period. For the study of such matters, I have tried to review the flow of the Korean culture into ancient Japan in the field of costume.
