An algorithm (breast sizer) was developed to measure the breast area using 3D scan data. Since the measurement value through this algorithm should be preceded by the measurement points setting, it should be compared with the setting of the direct measurement points verified in the previous study and standardized through this. Particularly, since the size and the breast shape should be considered for the breast area, 3D and 2D measurements were compared for subjects with large breasts and flat breasts. The 3D measurements in circumference, width, and depth were all larger than the manual dimensions and there was less than 1 cm of error in the measurement method in the breast-related details required to create a bra cup pattern. The difference between the two breast types was less than the difference between the two measurement methods. To reduce the error between the two measurement methods, it is necessary to set the measurement points to match the difference in the shape of the breast, to add the appropriate skin pressure when measuring differently to the flexibility and softness of the breast tissue, and to minimize the measurement error caused by setting the incorrect measurement points. Because of the different breast shapes, consideration should be given to the setting of the clear skin boundaries and measurement postures.

A breast model was for the human body was devised by studying a body scan and human body index of a desirable breast type. Thus, when manufacturing various 3D models, these results can accordingly become a fundamental basis for realizing a desirable breast model. This study aims to provide a basic data for designing the cup patterns of brassieres in order to improve the function and wearing comfort. The comfort of three kinds of brassieres were compared: one manufactured by the actual measured size; another manufactured as per the ratio of desirable upper and lower breast lengths; and the third manufactured by the 3D model attained by the desirable human body ratio. In this study, we suggest a process for realizing the desirable breast model using the ratio of bust breadth and waist front length, which are the components for deciding the appropriate position and size of breast, and which are easy to measure. The ideal breast shape is an equilateral triangle formed by connecting the nipple with the center of the clavicle. After deciding the interval between the nipples, this value can be used to configure the locations of nipples by drawing a tangent, with equal length, from the anterior neck point (which is the center of clavicle) to the nipple. Also, since inside points of breast do not exist, the outer point of breast, upper point of breast, and below point of breast on the same plane, and the depths from the nipple point to the respective points, are applied to simulate a 3D image, by modifications along the x, y, and z axes. Depending on the type of breast, the length from the center of shoulder to the nipple, the diameter of breast, upper length of breast, and the position of nipple, are different. In conical or protruding breast, the wearing sensation is better when the nipple point of brassiere was lifted, by modifying the upper and lower lengths of breast. Considering the wearing sensation and function of a brassiere, it was better to leave the wearer’s size as it is and use a pad within the same cup, rather than increase the basal area of the breast in order to increase the volume.

This research was conducted to help on the activation of internet marketing by providing the basic data about estimation on the method of introduction in internet marketing and utilization state according to college women"s ability of application and degree of preference on internet. The subjects were 177 college women residing in Cheongju. Collected data were analyzed by frequency analysis, analysis of variance, analysis of correlation, and cross-tabulation analysis using SPSS Win 11. The results were as follows; 1) Clothing items that purchased vis internet were casual wear, accessory, underwear, and formal wear in order. 2) The higher subjects were on degree of preference of window-shopping via internet, the frequenter purchased apparel products. 3) The ability of application on internet the more than degree of preference on purchasing effected on purchasing apparel products vis internet. therefore, apparel industry should be put to practical use this at internet marketing strategy.

The purpose of this study is to develope a new demining boots which has the maximum protective rate with impact absorption to the fragments of land mine.<BR> Under the necessity for the detecting and demining work in the summit with North Korea, the wearing behaviors and problems of existing boots are figured out by investigating the wearing conditions of military personnel participated in detecting or demining work. New demining boots is designed to decrease injuring fracture based applications on dispersion and absorption of impact.

This paper analyzes desirable breast types using measurements from 31 selected female subjects based on the ratio of breast in works of art and to design a brassiere cup design according to the breast type of 182 female subjects in their 20s. The subjects selected for this paper are somewhat larger than a previous study on aesthetically perfect breasts of foreigners according to chest breadth, center neck point to breast point, breast circumference, and breast volume. However, the aesthetic breasts of foreigners are larger than the subjects selected for this study according to chest depth, under-bust circumference, and bust point to bust point. Comparing various breasts types and aesthetic breasts, padding is necessary to complement the form of flat breasts to increase the volume and diameter. Brassiere cups for cone-shaped breasts should be designed to increase breast volume through an increase in nipple height. Hemisphere breasts should be designed to increase the overall volume-leaving diameter. Protrusion breasts should enhance the functions of aggregating and supporting without any increase or decrease of the breast volume. Drooping breasts require the ability to support a large volume to stabilize the breast. Subjects were selected depending on the ratio of breast silhouette as works of art and who have large breasts in disproportional to a slender trunk. Three items, the circumferential length of breast, height of the nipple, and the depth of inner breast using the anthropomorphic measurements of 182 subjects were measured through regression equations for breast volume. Breast volume = -394.86 + 27.52 × (the circumferential length of breast) + 18.73 × (height of the nipple) + 12.85 × (the depth of inner breast). Regression equations to extract the aesthetic breast volume in measurements irrelevant to breasts using the anthropomorphic measurements of 31 subjects were as follows. Aesthetic breast volume = -611.30 + 17.67 × (bust circumference) - 24.29 × (under-bust circumference) + 16.31 × (neck point to breast point to waistline) + 22.83 × (bust breadth) + 12.22 × (waist depth) - 8.34 × (interscye- front). This prediction equation is useful to develop a breast type brassiere pattern, complement breast enhancement surgery, or minimize the effect a mastectomy.

Many of the apparel business and fashion educational institutes in land adopt fashion shows employing fashion models. Draping is effective tool rather than flat pattern making in the majority of the complicated design works for the fashion shows. However for the different features between the dress form and the fitting model, problems occur.<BR> This study was performed to provide fundamental data on difference between the dress form and fitting models in flat and draping bodice pattern with three-dimensional clothing air volume and two-dimensional bodice pattern analysis. There are difference between flat and draping bodice pattern in shoulder length, shoulder angle, armhole and from bust circumference to waist circumference in back bodice pattern.
