The purpose of this study was to evaluate wearing evaluation method in order to propose well fitted bodice pattern. For this study, the subjects were drawn from obese boys at the ages 9 to 11. Wearing evaluation had use of 3 bodice type and 3 evaluative method. The appearance evaluation was to evaluate subjects by professional group. The functional evaluation was to valued subjects by self-evaluation. The quantitative evaluation was to estimate subjects through Electomyograph. Wearing evaluation was done through questionnaire of 32 item in objectivity, 36 item in subjectivity, and 36 item in quantity. The data were analyzed by using ANOVA. From wearing evaluation, appearance and functional evaluation had significant most of them but quantitative evaluation had not significant. It was known that the human sense was more sensitive the quantitative mechanism. And its obtained by both functional evaluation and quantitative evaluation, respectively was found to be significantly correlated, Independent relation was observed in the results from both appearance evaluation and functional evaluation as well as from both functional evaluation and quantitative evaluation. Therefore, we propose that it is proper to evaluate the propriety of bodice pattern for obese boys of school year, mutually compromising both appearance evaluation and functional evaluation or both functional evaluation and quantitative evaluation.

In this study, we tried to verify the effectiveness of 3D scans of clothed participants from 20 to 24 year old men in fit analysis process. Carrying out fit analysis, we used 3D scan data and direct fit evaluation with the basic garments made as semi-fitted bodice pattern for men. The result of fit evaluation through 3D scan data showed the expert rated fitting items more positive than direct fit evaluation. Even though, generally there was a no significant difference in the response between 3D and direct fit analysis. Only there was a significant difference in the response to the specific place such as the center front line, neckline, shoulder seam, and etc. There was a no significant difference between the result of 3D scan and direct fit evaluation in the subjects' group. Also the result of assessment of 3D targeting consumers showed very positive and interested in using 3D scans for fit analysis. The ability to rotate the 3D scans for a variety of views proved to be a very effective process to analyze fit. Moreover, digital data is easily accessed at any locations and any time. Fit analysis using 3D scans could be great tool for not only fit evaluation in research but also better fitting in apparel industry.

Currently, a lot of people are aware of their health and well-being, so they are concerned about their healthcare. 'Taekwondo' is one of the popular sports that Korean people are passionate about Taekwondo has also become globalized. The uniform of Taekwondo is gaining importance. Taekwondo involves a lot of movement, hence the pattern should facilitate the movement. In addition Taekwondo uniform pattern should meet the demands of functionality, fit and consumer design preferences. This study aimed to provide the basic data for development of Taekwondo uniform pattern based on design preferences and functionality to wearer satisfaction. The result of this method indicated fit and design details. Also, the length of pants, top, and sleeve was too wide, which has to more fitted for both of genders. For females, the breakpoint was too low, which requires some increase to make females feel more secure. In conclusion, the results of this study indicated that in order to increase 'Takwondo' value, Taekwondo uniform is required to be more fashionable and comfortable to wear, which could influence other sports wear.

With recent advances in 3D scanning technology, three-dimensional (3D) patternmaking is becoming a powerful way to develop garments pattern. This technology is now applicable to the made to measure (MTM) system of both ordinary and tightly fitting garments. Although the pattern of fitted clothing has been developed using 3D human data, it is still interesting to develop cycling pants by considering while-cycling body posture and fabric elasticity. This study adopted the Garland's triangle simplification method in order to simplify data without distorting the original 3D scan. Next, the Runge-Kutta method (2C-AN program) was used to develop a 2D pattern from the triangular pixels in the 3D scanned data. The 3D scanned data of four male, university students aged from 21 to 25, was obtained using Whole body scanner (Model WB4, Cyberware, Inc., USA). Results showed the average error of measurement was $4.58cm^2$ (0.19%) for area and 0~0.61cm for the length between the 3D body scanned data and the 2D developed pattern data. This is an acceptable range of error for garment manufacture. Additionally, the 2D pattern developed, based on the 3D body scanned data, did not need ease for comfort or ease of movement when cycling. This study thus provides insights into how garment patterns may be developed for ergonomic comfort in certain special environments.

This study used data from a survey of adult Korean women in their twenties to learn their current practices for wearing and purchasing tight-fit jeans available on the market as well as perceptions regarding size measurements and satisfaction levels. We then determined product sizes and pattern measurements for the type of jeans worn. This study also analyzed discrepancies in product size measurements among brands to determine whether the measurements were generally suitable for average body shapes and measurements of women in their twenties. The study results were as follows. First, the survey asked women in their twenties about current practices in wearing jeans. Many respondents answered that their preferred fit is "a perfectly snug fit" and that the most common fit style of jeans was the skinny fit. Second, we selected a test pair of jeans with an identical fiber content from brands that women prefer to wear, according to the survey results. We researched the product measurements of the size respectively labeled 27 inches for each of the 8 brands' test jeans; consequently, the results showed that there were significant differences among the brands in the product measurements of each part of jeans. Third, we analyzed the pattern measurements of 8 selected brands for each area and identified pattern characteristics by brand.

The purpose of this study was to provide some preliminary results on application of 3D scan data of head shapes to the hat design and pattern-making. This paper defined necessary measurement items and concepts in 3-dimensional images of head shapes. And also it presented the methodology to pattern-making of 6-piece crown hat based on 3D data. It used the data of Size Korea to pick up and choose a head shape model with the average head size of Korean women in their twenties. Main results were: 1. The 3D scan data of head shape was better than the 1 dimensional measurement data. Because I could establish a hat pattern-making theory by the 3D scan data of head. 2. The 3D scan data provided the basis for conceptualization of basic measurement points and items for a better fit of hats as well as the definition of the basic hat circumference. 3. This presented a methodology for analyzing out head shape by 3D scan data, and allowed the derivation of the basic hat circumference from the maximum head circumference. 4. As the 6-piece Crown cloche hat made by this method fitted the head shape model perfectly, this methodology could suggest potential applicability to various hat design.

This study focuses on looking at the influence of silhouette in the 1930s on fabric pattern design by comprehending how differently flower-pattern design were found according to clothing silhouette. The period scope of research was limited to 1930s, and the research object was set as the flower patterns seen in the designer's high-fashion and the women's daily apparel as well as the clothes for sports and leisure activities. Based on the above research scope, the researcher investigated the clothing silhouette and the textile patterns in 1930s by reviewing the literature about domestic and foreign books, research papers, domestic and foreign fashion magazines, information on the Internet. A glance at the women's clothing in the 1930s reveals that they emphasized something inactive, elegant, feminine and that great popularity was given to feminine silhouette that closely fitted the body and long and slim, as skirts became longer and longer. Like this, silhouette refused traditional methods in the technique of expressing flower patterns that were on-trend in that period, pursued the freedom of line and form, used shadowing technique by means of free pens and brushes and the effect of watercolors. It also arranged in a semitransparent way and painted contours alone, too. Flower patterns fell into two categories: amorphous abstract patterns and standardized abstract patterns. The patterns expressed themselves, divided into small-scale irregular patterns and abstract geometric patterns that filled the entire textile.

The shape of womens breast is the most important part of body silhouette. For the high-fitted clothes, in particular, more refined brassiere effective enough to show the beautiful line of female breast is asked. This study focuses on comparing the difference of the two different textiles of brassiere as to their effectiveness as a brassiere. The Stockman Lingerie Mannequin made by England is used for the draping method for the brassiere pattern. Two different brassieres of stretchable and unstretchable(cotton) textiles respectively were made out of this pattern, and the difference of effectiveness wearing the two brassieres was compared. 30 females ranging in the ages of 19 through 24, and whose size is 75A were selected as the test group who are to wear them. The result of each measurement proves that the cotton brassiere is more effective than the stretchable brassiere as a whole considering center concentration of breast, projection of breast, and bust up function. The result of the test on satisfaction of wearing brassiere was also in favor of cotton brassiere as to projection effect, bust up effect, making a good shape of bust. For the cup, in particular, unstretchable textile is more effective for making a breast look better.

Atomized liquid jets from the washing nozzle which configured with recirculation chamber for cleaning hot-zone area are accelerated and impinged on the head lamp surface. Cleaning efficiency of head lamp can be increased with injecting washing fluids into the hot-zone area. Experimental and numerical studies with various design parameters were executed to reveal the relations between internal geometry and internal flow in the washing nozzle. Spray structures were fitted with each of the head lamp surfaces and spray nozzles were optimized to the spray pattern. The recirculation chamber induces a recirculation flow and can be decreased the pressures perturbation inside the chamber. Orifice determines the mass flow rate. When the diameter of orifice is excessively large, it showed an unstable spray pattern. As a nozzle exit angle increases, density distributions are separated with two section. Also, as a protrusion length of nozzle exit increases, spray patterns are spread into a large area and density distributions showed unstable trend.
