Selected MPEG-b-PDLLA block copolymers have been synthesized by ring-opening polymerization with systematic variation of the chain lengths of the resident hydrophilic and hydrophobic blocks. The size and shape of the micelles that spontaneously form in solution are then controlled by the characteristics of the block copolymer template. All the materials prepared in this study showed the tunable pore size of 20-80 ${\AA}$ with the increase of hydrophobic chain lengths and up to 660 $m^2$/g of specific surface area. The formation mechanism of these nanoporous structures obtained by controlling the micelle size has been confirmed using both liquid and solid state $^{13}C\;and\;^{29}Si$ NMR techniques. This work verifies the formation mechanism of nanoporous structures in which the pore size and wall thickness are closely dependent on the size of hydrophobic cores and hydrophilic shells of the block copolymer templates.

This study was to carry out interview and survey of currently marketed foundation garment, focusing on manufacturers, on the basis of data of Year 2004 SIZE KOREA in 2004, to re-establish suitable age range and standard size, to simplify size interval scale and size system and to revise the standard for consumers' easy understanding and availability; The findings of this study are as follows. 1. Considering the age, in which a bra is worn, has reduced socially, the applicable age range was expanded into $8{\sim}80$ years old, which was divided into for junior and for adult. 2. For bra size, the standard title changed into the foundation garments size standard, in which girdle and bodysuit were included. 3. Basic physical parts for establishing for bra size are underbust and bust. Interval scale of under bust and bust was 5cm and 2.5cm, respectively. And basic physical parts are waist and hip girth for girdle, and underbust, bust, and hip girth for bodysuit. 4. For bra size, underbust girth was applied together with bra-cup size without 'cm' unit. For bra-cup size, difference between underbust and bust was represented as English alphabet. In other words, AAA means that difference between under bust and bust is 5cm. AA, A, B, C and D means that the difference are 7.5cm, 10cm, 12.5cm, 15cm and 17.5cm. 5. For girdle size, waist girth was applied together with hip girth without 'cm' unit. And for bodysuit size, underbust girth was applied together with cup size like bra size, and English alphabet represented hip girth range.

This study is to investigate the KS size recognition and mother's preference of female children's apparel. The practical research is performed for 150 mothers lived in Seoul and are randomly selected to their age, female children's number, education and income level. For statistical analysis and evaluation of survey data, frequency and percentage use contingency table. Findings in this study as follow: 1. Mother's preference for purchasing the girl's garments shows the significant differences of their subject characteristics such as age, girl's number, education and income level. 2. Mother's recognition about KSK 9403: 2004 sizing system for girl's garments does not show the significant differences of their subject properties. Most mothers only know the part of the KS size specifications because KS sizing systems are complex. So KS sizing systems must be simplified and respecified to understand the KS for mothers easily when purchasing their girl's garments. In summary this paper investigates mother's preference and recognition about KS sizing system for the girl's garments.

Pantyhose is a close-fitting garment. Consumers are highly sensitive to any progress done in fitting their lower body and increasing comfort. However, pantyhose manufactured in Korea are only one-sized. The purpose of this study is to suggest the size designation of pantyhose, using new human body measurement data which were gained from the Year 2004 SIZE KOREA project. For the purpose of this study, the ISO standards and JIS standards were reviewed and questionnaire was carried out to manufacturers and distribution companies. The results are as follows: First, for a difference with size standards established in 2002, applicable age range was expanded from 15 to 70 year-old women to entirely include persons who wear panty hose. Secondly considering the actual condition that panty hose is producing in single size in most companies due to its elasticity of material, number of size was reduced from five to four. Thirdly basic parts of body which were applied to panty hose are height and hip girth. And size of panty hose is decided by a chart which is composed of height-axis and hip-axis.

A brassier supports and protects breasts and makes a better shape of the upper half of the body through shaping breasts. A brassier, therefore, is recognized as the key underwear for female. Recently, the distribution structure and channels of the brassiere industry is diversified from conventional type of markets to department stores, convenience stores, and internet shopping mall. Studies on the sales of brassieres via internet, however, is not sufficient even though the market size has been dramatically increased thursdays. The study on the size structure (including the size and the materials fabric of brassieres circulating via internet) is especially rare. Therefore, this study tries to comply with increasing requests of consumers through comparing brassier brands on internet. In depth, this study compares cases of Korea and Japan in terms of availability of website on sales, quality indication like materials and functions, and size. The results indicated that there were three companies in Korea which run a website and make a sale through a website. All three Japanese companies operate a website and make sales on a website as well. In terms of size, Korean companies diversify their size of products in two ways. It varies from A cup to D cup based on cup size, and 65 to 100 according to its entire size. On the other hand, Japanese companies use AA, A to I to measure cup size, and 65 to 100 for entire size.
