The study aimed to analyze the functional differences in 3D virtual garment programs and compare body scan data with the corresponding 3D virtual models. We selected 3D virtual garment programs, formed virtual models in a representative size for high-school male cyclists, and analyzed them using the Design-X program. The results were as follows. In the 3D virtual garment programs, the anthropometric items for virtual model forming differed significantly from the standard anthropometric items suggested by Size Korea. Comparing the lower body scan data and virtual models formed by the 3D virtual garment programs, the biggest difference was in the shapes of the waist and hips, i.e., the flatness values of the waist and hips were different for each program in the cross-section view. In the lower body, a data-input-based program was needed for changing the exact measurement position of the waist circumference and hips' shape in detail. If a 3D virtual garment program provides functions for the virtual model's joint angle input and free motion transformation, it is expected to be widely used in the sportswear industry.

The purpose of this study was to investigate the effects of strength training on knee joint torque during walking in an adolescent with trisomy-21 Down syndrome. One adolescent with Down syndrome and one normal child participated in this study. Strength training consisted of eight exercises: squat, hamstring curl, hip adduction, hip abduction, knee extension, toe raise, sit-ups, and hyperextension of the waist. The participant with Down syndrome was participated in strength training for 12 weeks, three times a week, three sets, 10-15 RM; resistance was adjusted according to the principle of progressive overload. To measure the effect of strength training, isokinetic strength variables and knee joint torques were measured before training and after 12 weeks of training. The participant with Down syndrome had some abnormalities in controlling knee motion during walking due to muscle hypotonia, ligament laxity, and weakness of muscles. Post-training isokinetic strength increased compared to pre-training measurements. Knee range of motion were increased after strength training. Strength training did not affect ad/adduction and in/exteranl moments but did have an effect on flexor/extensor moment and timing.

Purpose: This study was to examine the effects of 12-week Tai Chi exercise on the autonomic nervous system activity and risk factors of metabolic syndrome in patients with metabolic syndrome. Methods: A single group pre-posttest was used. Subjects were 16 participants aged 51~71 years with metabolic syndrome. All of the subjects were met the criteria of the National Cholesterol Education Program-Adult Treatment Panel III (NCEP-ATP III). The Tai Chi exercise consisted of 19 movements from Yang and Sun styles provided twice a week for 3 months. Metabolic syndrome risk factors including waist circumference, blood pressure, glucose, triglyceride, high density lipoprotein cholesterol (HDL-cholesterol) were measured. A heart rate variability device was used to measure the activity of autonomic nervous system. Results: After 12-week Tai Chi exercise, systolic pressure, waist circumference, and HDL-cholesterol improved significantly. Tai Chi exercise had no effect on the autonomic nervous system activity. Conclusion: The 12-week Tai Chi exercise was partially effective in managing risk factors of metabolic syndrome. A larger study with longer period to improve the autonomic nervous system activity in patients with metabolic syndrome is needed.

A girdle is a body-shaping article of clothing. The garment pressure of the girdle is considered an indispensable factor. The purpose of this study was to identify changes in body size and distribution of garment pressure after donning the girdle. The changes of body size and garment pressure were analyzed by body types. Korean women (n=19) in their 20s participated in the experiment. Their body types were classified according to four factors: the index value(hip girth-waist girth), and waist, hip, and thigh girths. The garment pressure was measured at 12 points. The results of this study showed that the hip and thigh girths were reduced mostly after donning the girdle. These values were 2.0~2.8cm and 1.7~2.3cm, respectively. The garment pressure was high at the waist band, the hip joint, and the gluteal furrow region at the back. The subjects whose waists, thighs, or hips were well developed showed great garment pressure in the hip area, but their hip girth decreased very little. The subjects with less developed or slim thighs or hips showed a slimming effect, with moderate pressure in the hip and thigh regions. These results show that the hip and thigh can be slimmed with moderate pressure by donning a thigh-length girdle. High garment pressure is not necessary for the girdle's body shaping effect. The hip area is hard to get body slimming effect with high garment pressure. The current girdle sizing system needs to be revised in order to lower garment pressure in the hip region. The researchers suggest using 3cm size intervals rather than 6cm size intervals for hip girth.

This was written based on the type and structure of korean man's waist belt in the early and middle era of the Chosun era. The waist belt was excavated from the Mokdaldong in the Daejeon city. The types of korean man's waist belt in the Chosun era were classified into Wondahae (i.e., round shape belt) and Gwangdahae. The Wondahae consist of two types which are circle shaped and straight types. The circle shaped wondahae contain one fringe in the main body of the belt and its joint part is decorated with a small network such as lacing decoration with the size about 1 cm around. The shape of the Wondahae has been changed from the circle shaped into the straight types and also has a tendency to be wider and longer as time went by. The standard form of the Gwangdahae is straight with about 2-3 cm width and elaborated by lacelike fringe as well. This also has a tendency to be wider starting from the 1600s show. The structure of this belts were divided into braid and ornament parts. The ornament part was constructed with the lacelike netting and fringe parts. The sophisticated craft techniques have a great decorative beauty. Through an analysis of FT-IR, the materials of those three belt are known which are made of the silk and the core thread was filled with cotton. Moreover, it can be confirmed that the glitter material of the ornament part were designed with gold foil and has been analyzed with SEM-EDX.

This study investigated the demand for functional clothing that compensates for the physical deformation of women due to aging. For this, the degree of perception of physical deformation at the new silver generation was examined. The demand for functional clothing that corrects body shape and posture according to differences in age and degree of perception was analyzed. Study participants(n=138) were women who ranged from 55 to 65 in age. Perception of physical deformation was investigated in the categories of deformation of body posture, cognition of joint pain, and deformation of body shape. Analysis results showed that cognition of joint pain was the largest of the three elements of body deformation, and each element had a high correlation between each other. Perception for degree of body deformation for women in their 50's and 60's was similar. These results show that changes in posture or body shape occur severely from the late 50's, and this appears as joint pain. The group with a high perception of posture deformation showed an especially high demand for functional clothing that corrects body shape and posture. The group with a high perception of body shape deformation had high demand for functional clothing that corrects body shape by lifting the hips and the breasts, and making the abdomen and waist slimmer. The results of this study show that women of the new silver generation are attuned to deformations in body shape and posture as well as joint pain beginning in their mid-fifties. There is a need to develop functional clothing to correct posture and body shape for the new silver generation women.
