The purpose of this study was to investigate muscle activity of the lower limbs when walking in jeans in order to obtain basic information for development of new jeans patterns with excellent movement adaptability. Using three types of jeans (basic, medium, and slim) with different ease on hip, knee circumference, and crotch length, and two different types of shoes, Electromyogram (EMG) of the lower limbs muscle was measured for four healthy subjects walking on treadmills and stairs. EMG of vastus lateralis, semitendinous, tibialis anterior and medial head of gastrocnemius muscles was measured. The muscle activity was assessed in RMS (Root Mean Square) value of the EMG. On the treadmill in sneakers, only the vastus lateralis muscle showed a significant difference in RMS value depending on patterns. Basic and medium jeans allowed higher muscle activity than trunks of slim jeans did. On the treadmill in high heels and slim jeans, the RMS values of all muscles were significantly smaller than in basic jeans, whereas no significant differences were shown while in trunks or medium jeans. On the stairs either in sneakers or in high heels, no significant differences were shown between all muscle activities for all types of jeans. On the treadmill, greater fatigue was induced in all muscles from walking in high heels than in sneakers for all jeans patterns. When walking on the stairs wearing either type of shoes, however, the effect of jeans pattern on muscle activities was different from muscle to muscle.

The purpose of this study was to compare and analyze the pants pattern of the lower body of 70-85 aged women. I tried to present excellent pants pattern that is convenient and suitable for the activities of elderly women. Through this, I tried to provide basic data necessary for making elderly women 's pants. As a result of evaluating the appearance of the pants pattern according to the body type, the fit of the type 2 was evaluated as the highest in the item except the position of the front waist line. For the objective evaluation of the 3D simulation, the air gap of the pants by the body part analysis showed that there was not much difference in the air gap around the waist circumference, hip circumference, thigh circumference, and knee circumference by applying the same drawing method and body size. However, in type 2, the air gap of thigh and knee circumference parts was larger than that of type 1 and type 3. Because type 2's legs were thin but it used same size of hemline. It was thought that it is necessary to adjust the space of front and back crotch length to 1 inch (2.54 cm) instead of 1.9 cm (3/4 inch) so that the waistline position of all three types can be set up a little to cover the abdomen. This study was conducted to investigate changes in body shape of elderly women and to develop appropriate pants patterns.
This study researched the sizing system of dress form for apparel manufacturing in the domestic market. It aims to be used as basic data for the development of a dress form that could be used by manufacturers of senior men's clothing. Research focused on the sizes presented on the homepages of 17 dress form manufacturers in the USA, France, Japan, and Korea. Body measurement was made for senior men in their 50's over men (n=134). Six items were measured by the 'Standard body measurement of Size Korea'. The type of dress form in the domestic market can be classified into half-body type (upper body type and lower body type), torso, and whole-body type; in addition, each type is divided into upper arm, arm, crotch, and thigh. Korean dress form manufacturers produced/sold diverse kinds (size 7-9) for women; however, they used large/small sizes or product sizes for men without defining sizes. The chest size (93-105cm) has not been standardized while the rates of waist circumference, hip circumference and shoulder length (in accordance with the chest size) were all different. Global dress form brands manufactured reflecting body dimensions by the state organization USA ASTM. Japan JIS. For this reason, most domestic clothing businesses depend on imported dress forms. Especially, there were no dress forms for senior men. With the growing market for seniors, it would be necessary to produce senior dress forms for clothing production that reflect the body shapes and sizes of seniors.
The construction of athlete's tight-fitting garments by reducing the elastic knit pattern is an interesting subject, which directly influences the performance of the wearer. Therefore, relationships between the reduction rates of the men's pants pattern obtained using measurements of Size Korea 2004 and clothing fitting were explored to improve clothing comfort. Two pattern making methods were developed and the reduction rates were applied to those pants depending on the parts of human body. The four male subjects were university students in the ages of 20 to 24. Subjective wear sensations of the experimental garments were rated using seven Likert scales during 4 consecutive days. While wearing the garments, subjects were kept four various postures including waist flexion and sitting etc by requests of the researchers. Likert type scale was used for the evaluation and 7 point indicates that it gave the best fit as tight-fitting pants. As results, differences in the length and girth between two piece pants pattern(style 1) and one piece pants pattern(style 2) were 0.0$\sim$0.3cm. Between two pattern making methods, one piece pants pattern(the style 2) was superior to two piece pants pattern in terms of subjective sensation and fit. Among eight tight-fitting pants, C, D, G, H pants were superior in terms of fitting and stability of waist and hip part to the others. ill case of tight-fitting pants, the reduction rate of the pattern in the course direction, the reduction rate of T2/3(66%) was better than that of T/2(50%), but the reduction rate of the pattern in the wale direction, that of the part of crotch, which was very sensitive part, should be kept the same as suggested earlier by Ziegert(1988).

The purpose of this study was to establish a sizing system according to size and dimension whereby manufactured pants can be classified and develop men’s formal pants pattern based on the analysis of ready-made and educational pants pattern. The first, we surveyed the sizing and the basic pants patterns of the men’s ready-made wear companies, Secondly, through the survey data of the domestic men’ready-mad clothing industry, we proposed a new sizing system. Lastly, after compared three different types of ready-mad pants manufactured according to their patterns and an additional type of pants made after the educational pattern, the new men’s basic pants pattern were developed. The findings were as follows: 1. Survey of the domestic ready-mad garment industry showed that each company classified its own manufactured goods according to its own sizing system: moreover, they each used its own unique patterns which appeared to be resulted from a combination of two factors : the experience of a patterner and foreign know-how technology. 2. New sizing system was developed with 12 steps from size 74-88 to size 96-106 based on the high frequencies of the companies’3. New basic patterns for men’s formal pants were developed: Inseam length = 80cm, crotch line = H/4+4.6cm, pants ham = 23.5cm as basic lines and front waist girth =W/4+9.1cm as drafting line. 4. the superiority of the new basic patterns were been demonstrated by a high approval rate of the subjects who participated in testing.
The purpose of this study is in the investigation to relieve into the clothing inconvenience levels and to need by arthritis patients who experience clothing difficulties in daily living even without showing conspicuous physical disabilities. For this study, personal interviews were carried out with 151 female arthritis patients, using a questionnaire form consisting of a total of 206 items. Data analysis were done with spss 12.0 for the frequency analysis, cross tab analysis, t-test, and ANOVA. The findings are as follows. 1. The survey subjects were diverse in their age from 20s to 60s and 18.5% of them have need of other's assistance at the time of getting dressed or undressed of clothing. The knee part was felt to be the most uncomfortable, causing the inconveniences in wearing pants or panties. 2. The investigation into the inconvenience levels at the time of dressing or undressing of clothing was indicated that the wearing of pants was the hardest movement to arthritis patients, as the items relating to the movements for putting feet into or pulling them out of pants and those for raising pants over the hip were also accompanied by the feeling of pains. In addition, the aged arthritis patients felt the clothes-wearing movements more difficult. 3. The survey on the kind and inconvenience levels for the clothes currently being worn showed the highest wearing ratio for the pants, which were pointed out to be the most inconvenient. 4. As for the clothing improvement, the needs were located as a whole in the sufficiency in measures of pants crotch and circumference items, the flexibility in materials, the short length of pants, or the front clearance.
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 moisture-absorbing 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 aimed to develop a a custom-made dress form for draping using a live model's 3D body scan obtained from an entry-level 3D handheld scanners, 3D modeling software and 3D printing technology. A female subject was recruited whose body size fell under the normal (N) body shape criteria suggested by KS K 0051. First, the handheld scanner reduced the length of the legs in scanning, but most of the scanning operations between the neck and crotch levels were conducted accurately. Therefore, this study was designed to develop a torso dress form. The full body 3D scan was edited into a torso shape using ZBrush® software. Using Rhinoceros® and Materialise's Magics software, a 3D body scan was modeled so that the user could fit two types of mannequin stands (one with a neck fixation from above and one with an insert from below) to the dress form. The body scan was divided into 9 pieces to fit the printable size of the Stratasys 3D printer Fortus 250mc, and the cross-sectional distance from the center to the periphery was downsized by 2 mm. After outputting the dress form scan file with a 3D printer, the dress form was manufactured by the first covering it with a 4 oz nonwoven pad and the second covering with a single jersey material.

This research is the initial step for establishing a convertible body sizing table applicable to the Korean and American female apparel industry. All 3D female measurement data of the two countries were obtained from Size Korea Project and SizeUSA Project. The sample subjects used in this study were 1,988 Korean and 6,306 American females. Thirty-four(34) variables were chosen as the principal measurements in making garments. The conclusion of this research was as follow: First, it was determined that American women were larger and longer than Korean women in all measurement except shoulder slope measurement. Second, according to the differences analysis of the each age group in Korean Females, all measurements except hip girth had significant differences among the age groups. In case of American females, all measurements except arm length(shoulder to wrist) had significant differences among the age groups. Third, in the comparison of differences between the age groups of the two countries' women, some dimensions varied significantly with age, while others did not show any statistical significance among the age groups. Fourth, according to the t-tests of same age groups between Korean & American female measurements, American female measurements were larger and longer than Korean in all measurements except crotch length total, shoulder slope, hip girth-bust girth and hip girth-waist girth.
