The breast types of middle-aged women of 80A (formerly 80B) size were classified through a 3D scanned nude body. Thirty seven measurements including the radius of curvature, surface area, volume, surface length, and breast displacements were used as input variables. We extracted five main factors through the factor analysis of the measurements and classified 36 subjects into 3 clusters through the cluster analysis. As a result of the factor analysis, the size of the breast, breast sag, the curvature of the inner and the outer breast curve, the width of the breast, and the nipple direction were found as the main factors. For the results of the classification of breast types, Cluster 1 was characterized by narrow breast width and unsymmetrical under the breast curve, whereas Cluster 2 was a wide and sagged shape. Cluster 3 was classified into big breast volume and symmetrical under-breast curve. The results are useful to the product development of high quality brassieres which reflect the 3D characteristics of breast types of middle-aged women.

This study comparatively analyzed the changes in the dimensional stability and the mechanical properties of stretch knit fabrics associated with washings conditions in order to determine the most appropriate washing method. Polyester and spandex knit fabrics were washed 25 cycles with nine washing condition profiles that controled detergent, hardness. temperature and RPM. The knit fabrics with repeated washings were evaluated by dimensional stability and measured by the KES-FB system. Polyester and spandex fibers have good chemical resistance. However, the changes in the dimensional stability and the mechanical properties were observed in washed knit fabrics. After repeated washings, the knit fabrics washed in an alkali or neutral detergent had good dimensional stability compared with the knit fabric washed in functional detergent. The washed knit fabrics were extended, stiff, rough, and had a smaller volume. The changes were the result of the rearrange of polyester fibers which twisted around spandex core and chemical interactions involving the detergent and the physical and mechanical forces of washing. Especially, using an alkali detergent resulted in increased stiffness and roughness of the knit fabric. In conclusion, the washing in water with low hardness and a neutral detergent can minimize the changes in dimensional stability and mechanical properties of polyester and spandex knit fabric.

For design of early childhood children's footwear, this study was to analyze the properties of their foot. This study was performed in 200 male and 200 female early childhood children from 3 and 6 years old lived in susan urban area. There were measured 17 items of the foot and calculated 4 indexs for analysis. The result was as follows; 1 The growth rate differs from the sites of a foot. According to the growth of age, early childhood children's foot are more slender. 2. The average of foot print angle is $15~27^{\circ}$ and it is flat. Among the age groups, the numbers of 4 kinds of foot print angle are different siginificantly. 3. The average of metatarso phalanx angle is $174~178^{\circ}$ that is higher than adults'. 4. There are no significant difference between male children's foot and female childen's one except tarsal circumference and tarsal height. Tarsal part of male children is higher and ticket than female children's. 5. Because some of 3~6 age groups belong to the one foot length group, we should consider the age properties of foot in order to design footwears. When the size of footwear is divided by only foot length, the ranges of another measurements are larger than the range of foot length.

This study analyzes the foot shape of female high school students using 3D foot scan data based on a comparison with adult women (20s'-30s'). Data were collected from the foot anthropometry of 199 female high school students in Gwangju and Jeollanam-do. The right foot was measured indirectly by 3D laser scanner. There are 16 items in the foot anthropometric measurements. The $6^{th}$ Size Korea (measured by 3D scan data) is used for women's foot data. The results of the 3D measurements data investigation show that the foot length and foot width became longer and wider as the age increased. It is classified by three types after analyzing foot shape. Type 1 (28.1%) represented the shortest foot length, the narrowest foot width as well as the thick foot and long ankle shape. Type 2 (4.3%) represented the wide foot width such as the wide lateral ball width and semi-thickness shape. Type 3 (67.7%) referred to the widest foot width, flat foot and short ankle shape.

Effect of fixation methods and relaxation treatment on the dimensional stability and physical properties of MDPPA/HMM treated cotton knitted fabrics were studied. Combination of four different fixation methods - relaxation, swelling agent treatment, pad dry cure fixation, and wet fixation - were applied to flame retardant finish of 4 kinds of cotton knitted fabric with MDPPA/HMM. Then these fabrics were washed 10 times. As a result, In swelling treatment on 10G showed relatively higher value of length shrinkage than 14G. Length and width shrinkage were increased by initial washing treatment and no further change was shown after 6 washing cycles. After 10 washing cycles, length and width shrinkage decreased. The KES standardized basic value of B/W, 2HB/W and bursting strength of interlock were relatively larger than those of single jersey. The values of B/W and 2HB/W of cotton knitted fabrics were increased by relaxation and washing treatment but were decreased by swelling treatment. In addition, the bursting strength of the cotton knitted fabrics was decreased after fusing, washing and relaxation treatment.

This study researches the application methods of Wearable Technology (WT) realizing the convergence of Design and Electronics that could broaden the fashion expression boundaries to correspond to current convergence trends. For this, students in the Department of Fashion design and the Department of Electronics conducted an oriented convergence-design-workshop. The initial step of the workshop, included a lecture on WT including existing cases and brainstorming. As a result, two types of concepts; 'Light' using the lighting technology and 'Complex' using transforming and lighting technologies together were generated. Designers created garments that did not externally expose digital devices and engineers then configured basic systems with the minimum size of the devices applying. At the development stage, designers constructed internal structures of garments which do not influence the comfort situation and activities of those wearing the garments. Engineers then adjusted and finished the fashion prototypes' whole WT systems drawing on designers' guidelines. As the result of this study's workshop, the fashion prototypes were extracted by collaboration according to WT concepts; therefore, there could be the promising potential to broaden fashion expression boundaries through the application of WT.

To examine the effect of heat treatment temperature in finishing process on PET/PBT Fabric, PET/PBT Fabrics were treated at different relaxing temp., pre-set temp., and final-set temp.. The dimensions such as thickness and density were measured, and the handles were evaluated by Kawabata system. In relaxing which was wet heat treatment, thickness and bulkiness were increased, and NUMERI, FUKURAMI, SOFUTOSA, and THV also were increased but KOSHI was decreased with elevating temperature. With elevating pre-set temp., thickness and bulkiness were decreased, but KOSHI was increased. NUMERI, FUKURAMI, SOFUTOSA, and THV were the best at 180$^{\circ}C$ pre-set treatment. In final-set which was dry heat treatment like pre-set, thickness, bulkiness, NUMERI, HUKURAMI, SOFUTOSA, and THV were decreased, but KOSHI value was increased with elevating temperature. Therefore the best heat treatment condition was 130$^{\circ}C$ relaxing, 180$^{\circ}C$ pre-set, and 160$^{\circ}C$ final-set. And the handle of PET/PBT Fabric was affected much more by relaxing temp. than pre-set temp. and final-set temp.
