The purpose of this study is to provide basic data for more functional and more fitting clothing construction. The subjects were college women aged from 18 to 25 in June, 1997. Data were collected by anthropometry and photometry and analyzed by the characteristic of the upper body- The results are as follows: 1. After analyzing direct anthropometric data, 1 have analyzed the data by the characteristic in each somatotype, classified them and I have had 5 groups. Group 1 with middle height and standard type, group 2 with great height and standard type, group 3 with low height and slim type, group 4 with middle height and fat type, and group 5 with low height and a little fat type. 2. After analyzing indirect photometric data, 1 have analyzed them by the characteristic and I have had 4 groups. Group 1 with lean back type, group 2 with sway back type, group 3 with straight type and group 4 with bend forward type. 3. Through the mutual corresponding relation in the 5 groups classified with direct anthropometric measurement and the 4 groups classified with indirect photometric mea- surement, direct-group 1 comes the most corresponding to indirect-group 2, comes second to indirect-group 4, and comes third to indirect-group 1. Direct-group 2 comes the most corresponding to indirect-group 4, direct-group 3 comes the most corresponding to indirect- group 1, direct-group 4 comes the most corresponding to indirect-group 3, and direct-group 5 comes the most corresponding to indirect-group 1.

After its introduction in Korea, nail art is becoming active, especially among women in their 20s and 30s who are interested in fashion and beauty. Although self-nail tips are available online in various designs for each brand that is currently on the market, these designs and sizes of self-nail tips on the market are different for each age group. Since the design or size is not suggested for the different situations, there are difficulties in purchasing products that match the shape and size of nails of consumers. In this study, frequency analysis was performed using 'SPSS statistics 21.0 for windows program' to analyze data obtained by direct measurement method and 3D scanner measurement method for Korean women in their 20s. For comparative analysis between direct and 3D scanner measurements, a corresponding sample, 'T-test', was performed. As a result, we proposed the standardization of nail tip size after comparative analysis between direct measurement and 3D scanner measurement. Previous studies have been proceeding with direct measurement method. However, this study introduced a 3D scanner measurement method in the nail field and attempted the standardization of nail size by age group of Korean women. Importantly, this sutdy suggests standardization of nail tip size among missing body sizes.

This paper presents a novel method for radius measurement of fillet regions of polygonal models by using optimum onhogonal planes. The objective function for finding an optimum onhogonal plane is designed based on the orthogonality between the normal vectors of the faces in a filet region and the plane that is to be found. Direct search methods are employed to solve the defined optimization problem since no explicit derivatives of the object function can be calculated. Once an optimum orthogonal plane is obtained, the intersection between the onhogonal plane and the faces of interest is calculated, and necessary point data in the fillet region for measuring radii are extracted by some manipulation. Then, the radius of the fillet region in question is measured by least squares fitting of a circle to the extracted point data. The proposed radius measuring method could eliminate the burden of defining a plane for radius measurement, and automatically find a necessary optimum orthogonal plane. It has an advantage in that it can measure fillet radii without prior complicated segmentation of fillet regions and explicit information of neighboring surfaces. The proposed method is demonstrated trough some mea-surement examples.
