The purposes of this study were to investigate the relationship between anthropometric data of foot and other body sizes. to categorize the foot shape of elementary school boys and to find out determinant factors related the foot that enable us to deduce the foot shape and size for the design of more comfortable shoes. Subjects of this study were 249 elementary school boys of age ranged from 6 to 11 residing Seoul and lncheon area. Anthropometric sizes were measured with the direct measurement method using Martin scales and the indirect measurement method using digital photos. Pearson's correlation, factor analysis. cluster analysis. analysis of variance, post-hoc test, and cross tabs were performed for statistical analysis of the data by SPSS program. From the investigation on the relationship between foot-related items and body items, most items of foot measure were significantly related to body size items. However, angle of the foot did not related to other body sizes although other height items and mass items of the foot did have relationships with other body sizes. Results of ANOVA indicated there were significant differences in foot-related items except for items of foot angle and all body anthropometric items by subjects' age. This implicates big toe angle, little toe angle and foot ratio factors are required in sizing shoes besides foot length. On the basis of cluster analysis using factor scores. three different foot shapes were categorized. Type 1 was large and wide foot, Type 2 was small and narrow foot with large toe angle. and Type 3 was medium foot with no deformity on big toe. These three groups show significant differences in almost all measurement items. However, Rorher index and foot angle didn't show any significant differences among groups. This implicates the foot shape can be a determinant of shoe size.

A microwave device measurement tool kit using the TRL method for microwave tuner was developed. Teflon substrate was used for easy manufacturing. An adapter from CDI was used for the junction transition between microstrip and coaxial line. Mask production procedure which have the 3:1 reduction ratio was developed for microstrip transmission line manufacturing. Using these procedure the Cal Kit which can have Thru, Reflect, and Line was manufactured. TRL error correction method can be applied to the Kit. We tested the Cal kit and the error due to the microstrip line could be corrected. It can be applicable to the accurate measurement of microwave transistors.

The purposes of the study were to present the optimum slacks pattern for elementary school girls and to compare and evaluate wearing ease of the slacks. 3D scans using the Cyberware PS motion platform were carried out for 3 subjects who have different body type. The automatic drafting method was programmed by AutoLISP in CAD. Wearing tests using 3D Scanner was done for evaluation of fitness of slacks. Regression analysis, analysis of variance and post-hoc test were performed for statistical analysis of the data by SPSS program. The procedure and results were as follows: The slacks construction components for pattern drafting were derived from 10 horizontal section maps obtained from 3D scans. The automatic drafting was based on the measurements of slacks construction components and the curve of crotch line. The crotch line was drafted using of the arc function in AutoCAD. The total crotch length was calculated using the multiple regression equation. Wearing test represented that the slacks pattern developed to accomodate individual body measurements was estimated more highly than existing patterns.

The purpose of this study was to evaluate the effect of PEG onto warm/cool touch when the PEG was treated on the polypropylene fabrics. PEG with molecular weight 1450, which was expected to release heat at around 20℃ was selected. Add-ons were controlled to be 23%, 35%, 46% and 53% for woven fabrics and 20% for knit fabrics. Dry and wet specimens were also compared. For the objective measurement of warm/cool touch, Qmax was measured using KES-FB Thermolabo Ⅱ. Environmental temperature was simulated for 20, 30 and 40℃. Subjective sensory test were performed with 30 male and female subjects. Results showed that the increase in add-on did not contribute to the warm cooling of the woven fabrics, which is probably due to the hygroscopic properties of PEG. As the environmental temperature was changed knit showed the increase in Qmax at 20℃ and decreased at the higher temperatures. When the specimen was wet, Qmax was decreased for both types of fabrics and the difference was bigger with the knits. Subjective evaluation showed that the PEG treatment increased the stiffness but the knit was softer than the woven fabrics were.

The purpose of this study were to analyze the anthropometric data of feet of Korean women with aging, to categorize the women's foot shapes, and to compare the shoe size according to the foot shapes in order to provide the basic information for more comfortable shoes. Subjects of this study were 181 women over age 20. Theey were measured with the direct measurement method and the indirect measurement method, 26 items were measured from the right foot and 6 items were taken on foot outline. Factor analysis, cluster analysis, analysis of variance, post-hoc test, and cross tabs were performed for statistical analysis of the data by SPSS program. There were significant differences in height items, breadth items, girth items, and angle items by subjects' age. The older subjects' feet were wide and thick with big deformity on toes. The arch height of the older ones was low. This implicates that the degree of deformity on toes, the foot ratio, the foot girth, the foot breath and the arch height as well as the foot length are needed to be considered in developing comfortable shoes. Nine foot construction factors were extracted by the factor analysis of anthropometric measurements; foot size factor, heel and instep factor, malleolus lateralis factor, malleolus medialis factor, foot shape factor, shape of toes factor, heel height factor, big toe height factor, and intemal factor. On the basis of the cluster analysis, three different foot shapes were categorized. Type 1 was large and wide foot with little deformity on little toe. Type 2 was medium foot with defrmation of big toe, and with the lowest arch height. Type 3 was small and narrow foot with the highest arch height. Distribution of shoe size according to the foot shape was analyzed. The ball of foot breath was of wide distribution than the ball of foot girth. This implicates that girth items and breath items of the foot should be enclosed for the same foot length in the sizing system.

The purpose of this study was to classify lower body types of elementary school girls. The subjects for anthropometric study were 368 girls aged from 10 to 11. Factor analysis, cluster analysis, discriminant analysis, and analysis of variance were performed for statistical analysis of the data. Four lower body construction factors were extracted by the factor analysis of antropometric measurements. The factors extracted were lower body fatness factor, lower body height factor, lower body length from the waist to the crotch factor, and lower body configuration factor. On the basis of the cluster analysis, three different lower body types were categorized. Type 1 was short and small sized type and 42.4% of subjects belonged under this type. Type 2 was tall and fat type and 22.3% of subjects belonged under this type. Type 3 was the most similar to the average type having the largest waist-hip drop value and 35.3% of subjects belonged under this type. Discriminant analysis showed 7 discriminant factors that can classify the children s lower body type were Rohrer's index, height, fibulae length, waist girth, ilio cristale girth, trochanter girth, and weight.

The methodology of applying fabric stretch ratio in the pants pattern drafting was evaluated. The experimental fabrics employed in this study were 3 different knit fabrics with various stretch ratio in vertical or horizontal direction. The firm fitting pants pattern was modified by applying the fabric stretch ratio in vertical and horizontal direction. The computer automatic drafting method was used for pants pattern alteration. The suitability of the altered pattern was!' evaluated by the 7 clothing specialists. The results showed that fit of all experimental garments was improved in general. The garment which was constructed with the fabric having large difference between horizontal stretch ratio and vertical stretch ratio showed poor fit at crotch area. This result implies that computer aided pattern alteration is appropriate when fabric stretch ratio is vary by the fabric directions.
