Upcycling is a sustainable way to recycle waste resources and solve the global problem of environmental pollution. Upcycling is now attracting attention as fiberization and the disposal of waste clothing have become a serious issue. However, the customer's willingness to purchase upcycled products should be increased by propagating that the product value of a reborn commodity is of high value; these products are meant for new purposes and prepared with recycled materials. In this study, we created 11 designer items by applying an eco-friendly concept in the design process of upcycled textiles and products. From 2020 to 2021, a PBL(Problem Based Learning) curriculum was taught in design planning classes. The final 11 design items were derived after developing an eco-friendly product design for upcycled textiles. These final items were as follows: 5 fashion bags, 3 dog products, 1 clothing, 1 fashion accessory, and 1 sanitary mask design. In order to develop only one aesthetic design idea for upcycling, we considered the following features: user-centered convenience, functionality, and practicality. Then, tie-dye, drawing, patchwork, and embroidery were used to create innovative design items. The product design of recycled materials is based on high functionality, waterproofing, and the use of organic natural materials. The results of this study indicate that the creative product design of upcycling has contributed to a sustainable and eco-friendly environment. Related research studies must be conducted for innovating the continuous design process of the future.

After the corona pandemic, when consumers choose clothes, the issue of sustainability has become a more important selection criterion. The eco-friendly functional fiber used in the study is a smartcell, which has functions such as UV protection, decomposition of harmful substances, deodorization, antibacterial and biodegradation. This eco-friendly functional fiber was dyed using five kinds of natural dyes to examine the color change according to dyeability and dyeing conditions. As natural dyes, gardenia, turmeric, sappan wood, lac, and indigo were used. For comparison with smartcell, rayon, a cellulose regenerated fiber, and wool fiber, a protein fiber, were dyed under the same conditions to compare dyeability and color. The study results are as follows. It was found that smartcell had superior dyeability compared to rayon and wool in gardenia dye and showed lower dyeability than wool when dyeing turmeric, sappan wood, and lac dyes, but showed superior or similar dyeability than rayon. In case of indigo dyeing, the dyeability of smartcell was the best when dyed once, but it was found that smartcell had a lower effect on repeated dyeing compared to wool or rayon. Therefore, smartcell has superior dyeability compared to rayon fiber in gardenia, turmeric, sappan wood, and lac dyeing, and in case of indigo dyeing, it is suitable for light dyeing. When smartcell is produced as textile fashion products, natural dyeing is actively introduced and commercialized, and it is hoped that this study can be a reference material.

The aim of this study is to develop upper bodice pattern for obese girls aged 10~12 by using 3D virtual garment simulation system. The criteria for subjects in this study were girls who had over 1.46 of the R$\ddot{o}$hrer Index. A total of 229 schoolgirls who met these criteria were enrolled. The results of this study are as follows: First, by using 3D virtual garment simulation, new upper bodice pattern considered obese-schoolgirls was development. The basic numerical formula were as follows ; bust girth B/2+4.5, armhole depth B/4-1, waist girth W/4+0.5+dart amount, front chest width B/6+2, back width B/6+2, neck width B/12-0.5 and neck depth B/12+0.5. Second, armhole darts were added to compensate the loose amount of front armhole and dart manipulation was used to ensure a better appearance on armhole in the design. The dart side line was modified concavely to help cover the protruding stomach. Curved lines on the armhole were significantly relieved using dart manipulation and the darts side line was modified concavely to reduce the tightness around the front waist darts. Third, according to the results of the new upper bodice pattern's appearance evaluation, it estimated more highly than existing pattern in silhouette and ease amount, confirming that new upper bodice pattern was appropriate for the obese-schoolgirls. This study is expected to serve as one of important basic data for ensuing studies that may utilize 3D virtual garment simulation system with 2D patterns.

The purpose of this study was to examine the appropriate surplus of clothing for a jacket bodice pattern of middle-aged obese men by using the 3D virtual twin and virtual garment simulation system. The results were as follows ; 1. BMI rate of middle-aged males was 28.13 which was equivalent to mild obesity, whereas WHR(W/H ratio from waist to hips) rate was near 1.00 which was highly dangerous against their obesity. In case of middle-aged obese men, the WHR was significantly higher than the entire middle-aged men's average and the section shape in which their thickness was relatively more than width. 2. As a result of appearances evaluation through virtual garment simulation, the cut-off amount of the side seam and the center back was regulated accordingly. Hereby, the final tolerance range was set up at 21.15 cm at the hips, so that the appearances became better and the bilateral distribution of the cross section and space length was formed symmetrically. Especially in case of increasing the cross amount of hems to produce a natural silhouette of the waist-to-hips parts, the ease of buttocks was judged to be moderate, but it turned out that a wavy cross section was made and the silhouette was not good. Thus it was found to be not good that the ease of the hips became excessively increased in proportion as circumference of waist and belly were increased in obesity. The use of the virtual twin made it impossible to comprehend the appearances and ease correspondent to motions. In order to evaluate wearing fitness, therefore, the system should be improved so as to change arm positions and perform various motions.

The aim of this study is to help out-size consumers purchase the ready-made clothes and improve clothing fitness by classifying the lower bodies of abdomen-obese adult males and by setting up some size system according to each size interval of obesity types. The including criteria for subjects in this study was over 25 kg/$m^2$ of the BMI, over 90 cm of waist, and over 0.85 of WHR, and a total of 538 adult males satisfying them were enrolled. Results are as follows; 1st, the higher the age bracket was, the more increase in each age bracket's lower-degree obesity rate there was along with the more decrease in moderate-degree, while the higher the age bracket was, the more increasing tendency toward each age bracket's abdominal obesity there was. 2nd, 3 clusters were categorized by cluster analysis, into abdominal obesity, high-degree-type, trapezoid-type and cylinder-type. And 3rd, as a consequence of size system establishment according to lower-body types, the basic body sizes and reference body sizes were different according to types even in commonly-appeared size names at sections of respective types. The research findings above suggests that it is necessary to figure out the obesity types according to waist and hip sizes representing basic sizes and to design the patterns in consideration of the characteristics of obese body shapes when lower-half body clothes are designed among obesity groups. And it may be used as a basic data to decide the desirable output of production according to respective body types.

The purpose of this study was to develop torso pattern of underweight female in their 20s~30s by using Clo 3D virtual garment simulation system. The results were as follows; first, as a result of analyzing torso somatotype, underweight women showed lower average than average values of whole women in their twenties and thirties in the items such as length, width, circumference, thickness except for height. Second, by using 3D virtual garment simulation, new torso pattern considered underweight female was development. The basic numerical formula were as follows ; bust girth B/2+3.5, armhole depth B/4+0.5, front waist girth W/4+0.5+0.7, back waist girth W/4+0.5-0.7, front hip girth H/4+1+0.5, back hip girth H/4+1-0.5, chest width B/6+3.1, back width B/6+4.5, neck width B/12+0.2 and neck depth B/12+1.7. Third, by reducing hollowed amount of front, back, and side line, and hollowed amount of back center line, the reduced quantity was included to darts amount. Number of dart was adjusted to two pieces so that darts amount was equally distributed to two darts. Forth, according to the results of the new torso pattern's appearance evaluation, it estimated more highly than existing pattern in silhouette and ease amount, confirming that new torso pattern was appropriate for the underweight women. This study is expected to serve as one of important basic data for ensuing studies that may utilize 3D virtual garment simulation system with 2D patterns, and also for future 3D pattern production program development.

As children's apparel industry expands, there are many researches on purchasing and wearing children's clothing and optimal sizes, but researches on purchasing and wearing children's clothing and the appropriateness of sizes comparing average body shape and obese children are still inadequate. Therefore, in this research Late Elementary Schoolgirls ranging in age from 12 to 13 are categorized into the average or the obese body type, and by comparing and analyzing purchasing and wearing children's clothing and the appropriateness of its sizes between these groups, the problems in the size system of children's apparel are realized and the basic information about designing children's clothing for average body shape and non-average body shape(out-size)children are presented. The survey questions were composed of topics about general personal information, the purchasing practice and wearing practice, the appropriateness of its size when wearing children's clothing and the practice of mending apparel according to the satisfaction level of children's clothing sizes. Because subjects are often too big to wear children's clothing, and in the case of obese children the deviation of a body type is amplified, therefore in buying and wearing children's clothing, they demonstrate different forms of purchasing and wearing characteristics than adults. Considering the practice of increasing obesity in children due to westernized eating habits and decreased physical activities, along with developing programs for improving obesity, the development of an optimal size system in response to various body types will become an important challenge.

This study was performed to investigate purchasing practice and size satisfaction in order to establish marketing strategy and produce free-size clothes for the male and female in their 20s. Results were as follows; first, regarding the size selection method, it has been found that 71.5% of subjects answered that they buy clothes as a sales clerk chooses for them without knowing the old size name or notation. Second, 47.5% of subjects answered that free size is the size, which fits well to 55~66 size. Meanwhile, 36.1% answered that free size fits well to any body type; while 4% answered that free size fits well to 77 size. Third, regarding the clothes kind, which consumers buy most as free size, consumers buy shirts and sportswear by free size. Fourth, they were observed to purchase free-size clothes "free-size clothes what I want" and to not purchase clothes "due to the lack of right sizes." The size notation of clothes products is basic information, by which consumers can tell whether the clothes fit to self or not before the consumer would wear the clothes and confirm its fitness. Therefore, it is suggested that all clothes products would be manufactured by having KS clothes size as basic data and they would use standard size notation so that consumers would not have confusion. Standardized size notation by proper education and utilization on new KS notation method and attitude change of companies and consumers on size are suggested.
