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.

Introduction: To report the result of the thigh perforator free flap for the reconstruction of the soft tissue defect of the lower extremities and usefulness of this flap. Materials and Methods: We have performed 23 cases of thigh perforator free flap to reconstruct the soft tissue defect of the lower extremities between February 2004 and July 2005. The anterior aspect of the legs were 9 cases, the ankle joints were 4 cases, the dorsal aspect of the feet were 6 cases, the sole of the feet were 4 cases as recipient sites. The anterolateral thighs were 13 cases, the anteromedial thighs were 10 cases as donor sites. The size of the flap ranged from $4{\times}5\;cm$ to $12{\times}18\;cm$. The mean flap area was $73.2\;cm^2$. The length of the pedicle ranged from 5 cm to 15 cm. Every patient except children was operated under the spinal anesthesia. Results: 21 flaps (91.3%) survived, 2 flaps (8.7%) failed. In the 21 flaps that had survived, there were partial necrosis in 4 cases, which healed without any additional operation. In the 13 anterolateral thigh perforator flaps, 9 cases survived totally, 3 cases had the partial necrosis, 1 case failed. In the 10 anteromedial thigh perforator flaps, 8 cases survived totally, 1 case had the partial necrosis, 1 case failed. Conclusion: The authors had a good result with the thigh perforator free flap and believe that this flap is a good option for the reconstruction of the soft tissue defect of the lower extremities, because this flap has a thin thickness and it is easy to dissect the vessels. Moreover the patients can be operated with supine position.

Analysis of elders' behavioral characteristic during showering provides important fundamental data when developing an automatic showering system. We recorded showering behavior of 37 elders' at the front, back, left and right view using four CCTV cameras. The photographic data were analyzed by counting the frequencies of body scrub and identifying zones where hands could reach. And we measured their body sizes, and conducted questionnaire of showering for 302 peoples. Analysis was done according to the analysis criteria established. The human body was divided into 14 zones from a body, and the numbers of body scrub for each zone were counted. The average total numbers of body scrub were 170.8 excluding the head, the face and the neck. The average numbers of body scrub with right hand were 70.2, left hand were 88.2, and both hands were 81.8. The percentages of body scrub frequencies were 16.3% (breast), 12.2%(crotch), 8.8% (abdomen), 7.5% (waist), 8.8% (shoulder), 7% (hips), 0.4% (back), 15.2% (arm), and 23.9% (leg). Elders scrubbed the breast, crotch and abdomen more frequently than the back and hips. According to the video analysis and questionnaire results, the distribution of shower heads (or nozzles) at the front side should be arranged at the ratio of 40% of the trunk(breast, shoulders, abdomen), 20% of the thighs, the calves, and the crotch, respectively. The distribution of shower heads (or nozzles) of the back side were arranged at the ratio of 20% of the waist and the arms, 20% of the back, the thighs, the calves, and the hip, respectively.

On the subjects of the female adults in their 20s who love to wear jeans, the wearing reality of basic jean pants and engineered jean pants was examined while pattern comparison and the evaluation of appearance and functions were made to reach the following conclusions: 1. Wearing reality of engineered jean pants Among the examined subjects, 74.8% were found out to favor engineered jean pants. Those who have engineered jean pants turned out to pursue well-known brands more than practicality. 2. Pattern comparison analysis of basic jean pants and engineered jean pants Though similar sizes existed in pants tips and belt width, engineered jean pants showed bigger values in waist circumference, crotch circumference, hip circumference, knee circumference, thigh circumference and so on. There were no big differences in the front part except for the items like crotch circumference and crotch length, but engineered jean pants had bigger sizes in the rear part. Engineered jeans in the rear contained the outward curved silhouette of the legs, curved tips, and a dart design instead of a back yoke. 3. Evaluation of appearance and functions In the scores of appearance, basic jean pants were higher at 3.65 in the order of front > side > back. On the contrary, engineered jean pants were excellent in the order of side > back > front. In the items of functions, engineered jean pants were higher at 4.23 in the order of hips > thighs> waist > abdomen > knee > crotch. On the other hand, basic jean pants showed the order of knee > crotch & thighs > abdomen > hips > waist. In every movement, engineered jean pants revealed higher functionality. In particular, the bigger physical movement led to the greater functional differences between the two kinds of jean pants.

This study aimed to identify professional climbers'demand for movement functionality in pants worn for rock climbing and ice climbing. Data were collected through in-depth interviews with 12 professional climbers using a semi-constructed questionnaire. The respondents were instructor-level experts whose climbing ability ranged from 5.9 to 5.14 on the Yosemite Decimal System rating scale. The research findings were as follows. Experts wore different climbing pants depending on the type of climbing. For example, they mostly wore high-stretch, second layer pants for rock climbing, while layering first layer, second layer, and third layer pants for ice climbing. There were gender differences regarding the parts of the body in which climbers reported the most discomfort when wearing climbing pants; male climbers most commonly responded 'knees', 'inner thighs' and 'hips' while their female counterparts most commonly responded 'inner thighs', 'exposed back and waist' and 'hips' in that order. Differences were found between rock climbing and ice climbing in terms of wear and tear on pants, preferred fabric properties, and length of pants. Wear and tear was found mainly on the hips and knees of rock climbing pants and on the inner lower hem of ice climbing pants. Listed in the order of preference, the most preferred fabric properties were elasticity, light weight, and durability for rock climbing pants and elasticity, insulation, and protection against water and wind for ice climbing pants. Regarding the length of rock climbing pants, respondents preferred ankle-length pants and cropped pants that did not cover the feet. For ice climbing pants, respondents favored heel-length pants that prevented pieces of ice from entering the clothing. Men showed a high level of preference for ergonomically cut climbing pants. Respondents said the waistband on climbing pants should be simplified so as not to adversely affect climbing maneuvers.

Dynamic infrared thermography (DIRT) has been used for the preoperative mapping of cutaneous perforators. This technique has shown a positive correlation with intraoperative findings. Our aim was to evaluate the accuracy of perforator mapping with DIRT and augmented reality using a portable projector. For this purpose, three volunteers had both of their anterolateral thighs assessed for the presence and location of cutaneous perforators using DIRT. The obtained image of these "hotspots" was projected back onto the thigh and the presence of Doppler signals within a 10-cm diameter from the midpoint between the lateral patella and the anterior superior iliac spine was assessed using a handheld Doppler device. Hotspots were identified in all six anterolateral thighs and were successfully projected onto the skin. The median number of perforators identified within the area of interest was 5 (range, 3-8) and the median time needed to identify them was 3.5 minutes (range, 3.3-4.0 minutes). Every hotspot was correlated to a Doppler sound signal. In conclusion, augmented reality can be a reliable method for transferring the location of perforators identified by DIRT onto the thigh, facilitating its assessment and yielding a reliable map of potential perforators for flap raising.

This study was carried out to observe the effect of superheated steam combined with oven heating on the physico-chemical and sensory properties of chicken meat. Specially, chicken breasts and thighs were heated for 40 min in various heating formulations such as oven heating, superheated steam heating or a combination of two kinds of heating. In the physical properties measurement, the shear force was increased as superheated steam heating time and chicken thighs were higher than chicken breasts in all treatments (p<0.05). The highest level of water holding capacity was solely superheated steam treated chicken for 40 min (p<0.05). The $L^*$ value was decreased but $a^*$ value or $b^*$ value were increased after cooking. Chicken breast exhibited a higher colour value than chicken thigh. Superheated heating was effective to reduce heating loss as 22.64% (p<0.05). However, pH was not different depending on the heating formulation or part of the chicken meat (p>0.05). In the sensory test, the combination of 10 min oven heating and 30 min superheated steam heating was effective to create a good flavour of chicken meat. In this study, an optimum formulation was developed which was a combination of 10 min oven heating and 30 min superheated steam heating. It was more effective to improve the quality of chicken meat than the single heat treatment of chicken meat.

Background The result of illicit polymer injection is chronic inflammation with foreign-body granuloma (FBG) formation. Treatment can be divided into medical and surgical. Some patients develop severe complications with need surgical treatment. This study aims to describe patients who underwent surgical removal of the FBGs and autoimmune/inflammatory syndrome induced by adjuvants (ASIA); additionally, we evaluated the quality of life after surgery. Methods In this retrospective single-center study, the authors examined data of patients who underwent surgical removal of FBG caused by illicit polymer injection for cosmetic purposes and confirmed ASIA from 2015 to 2020 by three different surgical approaches. Descriptive summary statistics were reported on patient demographics, presenting symptoms and clinical examination features, treatment strategies, histopathology reports and quality of life. Results The cohort included 11 female patients with FBGs and ASIA. The most affected anatomical zones were the combination of gluteal region, thighs and legs (40%); and thighs with legs (20%). Main presentation was: skin hyperpigmentation (90.9%), skin induration (63.6%), chronic fatigue (63.6%), and ulcers (36.4%). Surgical modalities consisted of: ultrasonic-assisted liposuction in four patients (36.4%); open en bloc excision and primary closure in four patients (36.4%); and open en bloc excision and microsurgical reconstruction in three patients (27.2%). The postoperative quality of life visual analog scale score was 83.9. Conclusions ASIA treatment represents a challenge for the plastic surgeon. Adequate surgical treatment emphasizing, when possible, the total or near-total resection of the FBG must be performed to improve ASIA evolution.

Squatting of agricultural work can cause musculoskeletal disorders due to excessive pressure and rotational force on the knee joint In order to improve the assistive chair used in squatting agricultural work so that it can be used in a narrow groove, it is intended to improve the musculoskeletal harm of squatting work by attaching a spring on the assistive chair. Therefore, in the presenty study, 3D drawing was done using ProEngineer (3D), and a mock-up was produced and tested. Using pro-Engineer, it was judged that it was rare for plastic to be broken by a spring, so the analysis was conducted with a focus on springs. It was found that the structure that can absorb the shock according to the rigidity of the tape spring and balance the body is that the power to withstand the load of the weight is distributed as a whole when five springs are used. Electromyography was measured using ME600 (Mega Electronics, Finland) Measuring equipment attached to the waist, thighs, calves, and shins. EMG values were measured and compared with the prototype in two ways, when the worker did not wear the product and when he wore an existing product on the market. As a result of the experiment when using the prototype, the maximum EMG value for each part is considered to be helpful in preventing musculoskeletal diseases as the amount of muscle used is reduced in the waist, thighs, calves, and shins.

The aim of this study is to show the effect of starting block angle on the starting motion of sprinters using a crouching start. After installing starting blocks on forced platform, and having four highly comparative sprinters use the starting blocks, I analyzed the angular momentum of a crouching start. From the results of the analysis, the following conclusions could be drawn: There were differences of angular momentum both in body's X, Y, and Z axes and in the thighs' X axes, but not in the pelvis and lower legs. As to the general change of block angle, we noticed that an angular momentum for each segments was higher at an angle of 50 to 55 degrees.
