This study analyzed 214 sports knee braces found on Chinese websites between October 2022 and November 2022 to assess product type (impact protection material, fastening method, and protection method), material composition, size, weight, and main characteristics. The product type was further categorized according to (1) use of hard guard and soft guard protection method; (2) cover type, strap type, and slip-on type fastening method; and (3) pressure type and support type protection method. It also noted the physical shock protection materials used, including foam (EVA or polyurethane) attached to joints as a buffer material and plastic (TPU or PP) that protects the user’s knee from external impacts. The study found that the materials that primarily comprise sports knee braces are a combination of nylon, polyester, and neoprene. Additionally, it found that most sports knee braces available on the market are available in three sizes based on knee circumference: M (35–38cm), L (38–41cm), and XL (41–44cm), while some products are available in one size only. Furthermore, the majority of the 214 products studied weighed 200g, followed by 1,000g. Finally, in terms of product characteristics, many sports knee braces utilize ring-shaped silicone pads to distribute the load pressure on the knees or incorporate sturdy adhesive velcro to improve knee stability.

This study aimed to suggest a suitable collar pattern by visually evaluating the appearance of the amount of collar drape by the starting position of the lapel line of a double-breasted tailored jacket using a 3d virtual fitting program. It created an avatar based on the mean size of women in their 20s (the 8th Size Korea) using clo network (double fastening: 10cm, collar width: 4.5cm, collar stand: 3cm, and lapel width: 8.5cm). The starting of the lapel twist line was waistline level, the 1/2 level of bustline and waistline, or bustline level, and collar laying amount was 4.5, 5.5, 6.5, or 7.5cm. It was evaluated by garment construction experts using 5, 6, and 4 items on the front, sides, and back, respectively. Descriptive statistics, F-test, Duncantest, and reliability analysis were conducted using SPSS 22. When collar laying amount was 6.5cm, it was best rated regardless of the starting point. Under waist line, when collar laying amount was 6.5cm, it was best rated regardless of the starting point. When collar laying amount was large, the collar’s outline length increased, resulting in unnecessary wrinkles from the neckline to the lapel, affecting the overall collar appearance. When collar laying amount was the smallest, the collar was lifted and the width was narrowed, exposing the seam connecting the collar and neckline. The length of the collar’s outline varied depending on collar laying amount, which was important to make the outline sit comfortably on the body.

This study initiated research aligned with the body positivity movement, aiming to explore size diversity for groups facing relative size discrimination due to their deviation from average body types. Using KS adult women's apparel dimensions as a reference, jackets were developed for women in their 20s to 30s who belong to the small petite-size (S[P]) category, which is characterized by a height under 155cm (petite) and a bust-circumference from 72cm to less than 82cm (small). Using 3D virtual-fitting, we conducted experiment-pattern production and refinement and subsequent real-fitting evaluations by participants to objectively validate aesthetics and comfort. The study’s findings are as follows: First, utilizing a 3D virtual-fitting program by identifying ‘creases’ and ‘garment pressure points’ in the jacket appearance, experiment patterns were refined and real jackets were produced. This approach addressed challenges in recruiting participants with specific body types and allowed for efficient research in terms of cost and time. Second, through real-fitting evaluations, basic-fit and slim-fit jackets labeled as <79-88-150> were developed for the S(P) size. we presented ‘size spec’ and ‘ease allowance’ for jackets by waist fit. Both fits received positive evaluations with approximately 53.5cm sleeve length, and 11.7cm shoulder length. The ease allowances for the basic-fit jacket were approximately 9.2cm at the bust circumference, 12.8cm at the waist circumference, and 6cm at the hip circumference. Similarly, the slim-fit jacket exhibited ease allowances of about 4.8cm at the bust circumference, 4cm at the waist circumference, and 4cm at the hip circumference, receiving positive evaluations for aesthetics and comfort.

The aim of this study was to provide data to enable the development of skateboarding pants. From the Chinese skateboard club SNS, 126 skateboarders in their 20s and 30s were chosen to participate in a survey. Data was gathered using a questionnaire from May 14 to May 28, 2021, and then analyzed using SPSS 23. The results concerning production were as follows: clothing sizes are generally divided into six stages: XS, S, M, L, XL, and 2XL. The silhouette is wide, and most pants have e-bands and normal hems. The pants are made from cotton-blend fabric, which is mostly moistureabsorbing and quick-drying. Baggy pants are preferred by skateboarders, with cotton being the most common fabric. The crotch, knees, and buttocks of pants are the least satisfying for skateboarders. When they skateboard, their ankles sustain the most injuries, followed by their knees and wrists. In the survey of consumers’ preferences for skateboarding pants, different styles were rated in the following order: straight pant silhouette, ribbed knit and string waistband design; full-rise waist height, string hemline design; and ankle-high pants length (fit), fabric and design. The hygroscopicity and ventilation of the fabric are crucial considerations when purchasing pants. In terms of color, chromatic and pastel colors are most popular. In addition, some people expect new fibers to be used and expect protective equipment and pants to be integrated.

This study analyzed product conditions in terms of “size system,” “clothing construction depending on fit,” “details,” “colors,” and “prices,” with an emphasis on young contemporary brands for spring/summer 2021, in order to provide basic data for the development of small-sized women’s jackets. Out of 96 domestic and foreign brands, the study analyzed 254 small-sized jacket products from 23 brands that produce size-XS jackets. First, when examining the sizes for women’s jackets, we found that 8 out of the 23 brands offer a size-XXS option. After conducting tree analysis to analyze the factors affecting the production of size-XXS, the study found significant results in the areas of “distinction between domestic and foreign brands” and “product price.” Second, after categorizing small-sized women’s jackets into 3 categories— fit-slim, basic, and straight—the study analyzed clothing construction elements depending on fit. This seasons mainly feature straight-fit’s hip-line length jacket, a 4-panel pattern, and a panel without a waist dart. Third, the study, through the analysis of the colors of small-sized women’s jackets, found a higher frequency of colors in the order of black (23.0%), white (13.3%), and beige tones (10.1%), with additional colors such as sky blue, rose pink, and aquamarine in production, which exhibit the senses of the seasons. Price analysis revealed that small-sized jackets constituted a price range at the mid-to-low end, as in ₩50,000-100,000 (30.3%), ₩100,000- 150,000 (19.3%), and ₩150,000-200,000 (11.8%).

In this study, the sales status of female ball-jointed dolls and their parts were investigated and analyzed. Baseline data from 194 products and 54 brands on domestic and international Internet sites was gathered for the manufacture of ball-jointed dolls and the development of prototype costumes for them. The results are as follows. First, the sizes used for ball-jointed dolls are SD, USD, MSD, 13SD, and 70SD together with height. This study analyzed 39 sizes (15~70cm) by classifying them into numbered groups: 1 (15~22cm), 2 (23~33cm), 3 (35~51cm), 4 (53~62cm), and 5 (63~70cm). The price varied depending on the size; for example, 50cm dolls were approximately 45,000 won, while limited editions were sold at high prices, regardless of their size. They were classified into designs according to their body proportions and facial features as follows: 7- or 8-head-figure, 5-head figure, and 3-head figure, and were presented proportionally as images of women, adolescents, and infants. Second, the head was incised so that the top could be removed horizontally or the facial region vertically, allowing attachment of the eyeballs (which were either glass, resin, or acrylic) to the inside. More than 30 different colors were sold. Various wig styles were provided, including cut, short hair, and perm. These were made from human hair, heat-resistant fiber, and artificial hair. For the hands, there was a design expressing human hand gestures. For the feet, heels were in the form of wearing either high-heels or flat soles.

The purpose of this study was to review materials that could provide basic data about sports brassieres. In this study, 486 sports brassieres were collected online from 31 brands between November 2015 and February 2016. First, the comparison of compression and encapsulation in sports brassieres identified many different styles. The characteristics of compression brassieres included a cut cup, the front center height of a full cup, round neckline, short front hem, all in one shoulder strap with a patterned racerback design, all in one closure, no wire, and separation cup styles. The characteristics of encapsulation brassieres included a V-shape neckline, mixed round shoulder strap design, back closure, and all in one cup. Second, the comparison of domestic and international sports brassieres sorted the items differently. The characteristics of domestic products included compression brassieres, non-cut cup, the front center height of a full cup, round neckline, short front hem, an all in one shoulder strap with a patterned round design, all in one closure, no wire, and a separation cup. The characteristics of international products included a cut up, racerback shoulder strap design, and an all in one cup. Third, the analysis of domestic and international sports brassieres sizes found that six options were available for domestic compression sports brassieres and nine sizes were available for international products. Domestic encapsulation sports brassieres offered five under bust sizes and five cup sizes. International products offered eight under bust sizes and sixteen cup sizes.
