This study focusses pattern draft and grading of jeans for women in their 20s, who consume jeans the most. Pattern was drafted based on existing patterns collected from companies. It is different from the existing educational patterns. It suggests new sizing system for twenties referring to sizes used companies and grading rule and method. he results were as follows; 1. Companies manufacture 2-8 sizes and they referred to the Korean Industrial Standards, KS K 0051, for their sizing system. 2. Drawing method for Pattern of the study had following measurements for each part: in the case of waist circumference, front part was W/4+1.5cm, back part was W14+2cm, front hip circumference was H/4-1.5cm, crotch line was the crotch length (practical measurement), hip circumference was (upper crotch line length)/5+0.5cm, front crotch part was 2.7cm, back crotch part was W/5+2.7cm, knee height was (the length of leg)/2+6cm and the circumference of knee and the tip of pants were 40cm. Through the wearing test on the subject of twenties, researched pattern received higher ratings, especially in appearance than the existing pattern. 3. 5 sizes system was made referred to the sizing system of companies and National Anthropometric Survey of Korean in 1997 Grading rule for 12 grading points of front part and 13 grading points of back part was suggested. Results of wearing test on the graded patterns showed high ratings similar to standard size.

The purpose of this research was to evaluate the size fitness of ready-made jacket and their demands through the survey of the middle aged women, and having them try on the jackets, and present the basic data on the ways to increase the fitness by better size controls. The jackets, that were modified and improved through the experiment of the women with triangle-figure in their 50s, were compared and evaluated. The experiment showed a difference in the appearance and the motional function. The triangle-figure had the lowest fitness, thus most uncomfortable. The triangle-figure is characterized by the large waist, leaving small space between body and clothes. This creates the wrinkles in bust or waist area, making it uncomfortable to move. The jacket, that was produced by modifying these problem areas and developing research pattern, showed a good results on the appearances and function.

Tight fitting glove pattern is necessary to convey oscillation to the skin from the sensors attached on the hands as found in the haptic device. However, it has been difficult to provide customized glove pattern for haptic device so far. The objective of the paper is to develop a 2D pattern that fit tightly to hands by adopting the recent 3D technology to the clothing science. In this study, the user graphic interface application software(2C-AN) for the semi-automatic garment pattern generation has been utilized to develop the methodology of construct tight-fitting glove pattern for the hand in natural position. A basic pattern was developed directly from the 3D images of hand and the verification of the proposed pattern was also provided.

The purpose of the paper is to find the elements of jacket pattern far the obese women who went to slenderize their shape by optical illusion. Representative four subjects participated in wear tests. Subjective evaluation of the visual appearance we collected and, at the same time, 3D clothing air volume was observed for the four types of experimental jackets. As results it was found that narrower shoulder width, back upper width, and front waist width resulted in slender look, however, back abdomen width and front shoulder length induced more slender appearance in waist area. The result of the distance between clothing and skin measured by 3D scanner clearly demonstrated the distribution of ease due to the elements of pattern, which is useful to find the pattern variables responsible for the slender appearance of the obese women.

This study identifies methods to design patterns for jeans that are suitable for women in their twenties. Five patterns suggested by previous researchers were used to draw the same size of jeans (waist 67 and hip 91). The author compared and analyzed the measurements and shapes of the patterns, ranging from waist to crotch. Samples were produced based on these patterns and then tests were conducted to observe the dynamic functions and exteriors of the samples. The dynamic functions observed in this study include walking, ascending stairs, descending stairs and sitting on chairs. The results of the current study are as follow. The best evaluated pattern in terms of exteriors is the one where the hips and thighs are tightest compared to other patterns and where the back part is wider than the front part. This pattern also received high evaluations in dynamic functions due to comfort when walking. Regarding ascending or descending stairs, the tests found that all its parts (except the front crotch) are more comfortable than those of any other patterns. All these results show that a comfortable fit and easy movement is possible when the crotch width of the back is broader than the hip width so that the hips are comfortably supported.

This study provides basic data to develop a brassiere pattern that can cover the big breast of breast enlargement patients. In this study, we also showed areas of the brassiere cup pattern and the body surface of the breast on a breast enlargement patient. The results of the study are as follows. Correlation analysis was obtained between volume and body surface area and breast detail dimensions. After the correction process, we proposed a research bra pattern for breast augmentation patients. The cup-boundary in bra patterns of breast enlargement surgery patients is longer than the bra patterns of the general breast; therefore, the height of the inner and outer edges of the upper cups is higher. Also, it is necessary to set the new breast upper point when measuring the upper length in patients with breast augmentation surgery because the points of circumference of the breast are marked higher than chest circumference.

This study improves the fitness of Air Force winter service uniforms through the development of a shirt pattern drafting method and automatic pattern drafting program for MTM production. A calculation formula is formed through a correlation analysis and regression analysis using Size Korea 2004 3D measurement data after analyzing 4 kinds of existing shirt pattern drafting methods and 3 types of shirt patterns currently used for the Air Force service uniform. The results of this study are as follows: The developed pattern drafting method has 4 parts that use calculated dimensions: neck base width, front interscye, back interscye and scye depth. Other body measuring parts that have a high correlation with calculation parts are inserted into regression analysis as independent variables to create dimension calculation formulas. The result of the final study patterns were better than existing winter service uniforms in nearly all items for the appearance evaluation and motion adaptability evaluations. The method was converted into an automatic pattern drafting program using C++ after the completion of pattern drafting method development.

This study was to develop an ergonomic Korean male military winter jackets (inner and outer) pattern. First, we developed a prototype pattern and sample jackets based on a previous investigation for fitness and motion suitability of Korean male military winter jackets and evaluated fitness and motion suitability by a wearing test. The evaluation results were positive with an over 3.0 (5.0 Likert scale) for both the inner and outer jacket. However, a relatively low score was shown in the sleeve length and collar front height at the inner jacket and shown in hem circumference, neck circumference, elbow and front neck at the outer jacket. Next, we developed the secondary pattern and sample jacket reflecting the prototype evaluation result and executed expert evaluation. The result showed that the ease amount was appropriate (except for the collar back height) and the appearance was good. Finally, we developed a final pattern that showed good results after evaluation at a Korean military army base.

This study examined the sales pattern relationship with respect to product attributes to propose sales forecasting for fashion products. We analyzed 537 SKU sales data of T-shirts in the domestic sports brand using SAS program. The sales pattern of fashion products fluctuated and were influenced by exogenous factors; therefore, we removed the influence of exogenous factors found to be price discounts and holiday effects as a result of regression analysis. In addition, it was difficult to predict sales using the sales patterns of the same product since fashion products were released as new products every year. Therefore, the forecasting model was proposed using sales patterns of related product attributes when attributes were considered descriptive variables. We classified sales patterns using K-means clustering in order to explain the relationship between sales patterns and product attributes along with creating a decision tree classifier using attributes as input and sales patterns as output. As a result, the sales patterns of T-shirts were clustered into six types that featured the characteristic shape of peak and slope. It was also associated with the combination of product attributes and their values in regards to the proposed sales pattern prediction model.

This study investigated fabrics, washing and cares, design, pattern, subsidiary materials, and sewing methods with a focus on the functional outers using moisture-permeable waterproof fabric as a shell; in addition, each element was analyzed for differences depending on fabric type. The characteristics of 34 outers were investigated through labels, online product introductions, visual inspection, observations from two experts with more than 30 years experience and wear tests. Moisture-permeable waterproof fabrics used for the outer were classified into two types; in addition, the shell of the high-density fabric and the 2 & 3-layer fabrics had different characteristics. Various fabrics, detailed designs, and three-dimensional patterns suitable for each part of the human body were used to improve functionality. In addition, various subsidiary materials and sewing methods were used to form an organic relationship. The same washing and cares, patterns and subsidiary materials were used regardless of fabric type; however, the fabric type influenced the detailed design and sewing. The outers with high-density fabric had a loose fit, short placket, e-banded cuffs, lock-stitch, and lock-stitch+binding. However, the outer with 2 & 3 layer fabric had a slim fit, hood width adjustment, zippered pockets, cuffs with tab, seamless adhesive sewing such as laminating, lock-stitch+ seam-sealing, and welding.
