Recently, researches of piezoelectric energy harvesting were tried and in this study, a piezoelectric energy harvesting clothes was developed. First, piezoelectric energy harvesting zone on the extremities were drawn by 3D motion capturing and as a result, the hip, the elbow, and the knee were determined. A new structure of piezoelectric harvester was developed for appling to clothes. Because it needed to be flexible and sensitive for human body, the 2 layer stacked structure was proposed. A prototype of seamless garment was designed for a harvesting clothes because it needed to be body-tight and not to restrict the movement. High peak-to-peak voltages were acquired from the energy harvesting clothes.

This study analyzes changes in the knees, hips, and hip joint length according to the different angles of bending knees by 45°, 90°, and 135° respectively for knees, hips, and the hip joint that have high fracture rates when falling down. The research subjects were 10 elderly women in their 60s (or older) that obtain data collected through direct measurement. For analysis, the study drew a diagram of elongation and shrinkage based on changes and change rate from a straight posture (0°) and conducted a statistical analysis on differences of body surface length by zone according to movements. The more the knees were bent, the vertical surface length in front of the knees, the horizontal surface length above the knee line, the horizontal body surface length below the knee lines on the back, and the vertical surface lengths between front side lines and the side lines increased; however, the vertical surface length on the back decreased. For the hip joint, the difference in the vertical surface length was more distinctive when compared to the horizontal. Finally, the horizontal surface length increased below the hips and the vertical surface length increased in most areas except the sidelines and the front. The result of the change in body surface length according to the movements of this study can be utilized in the development of the motion-variable protector.

Purpose: The buttocks region has been associated with allure and sex appeal for centuries. Gluteal implants enable buttocks remodeling in a way that is not possible in other methods. One of the reasons that render gluteal implant surgeries unpopular is the fear of complications, the main problems being seroma, wound dehiscence, extrusion, and a visible or palpable implant. The authors present the XYZ technique, which provides anatomical reference points to guide the intramuscular dissection procedure in a feasible and safe way, resulting in a lower complication rate. Methods: The XYZ procedure was done for buttock augmentation on 8 patients from December 2009 to June 2010. Patient's ages ranged from 27 to 44 with a mean age of 36. Seven patients were applied the 250cc sized Elastomer implants with one patient 290cc sized implant. Preoperative marking was done with the patients in the standing position. Bisection of the gluteus maximus muscle was done at the midpoint thickness to create a plane for implant insertion, which is called the sandwich plane. Results: The 8 cases were performed safely without major complications. However one patient had minor wound dehiscence, and was managed with conservative treatment. Another patient had a discomfort on the buttocks for a long time. The patients were followed up for average 6 months. All patients were satisfied with the aesthetic results. Conclusion: In performing the XYZ technique for gluteal augmentation, the surgeon must split the muscle into two equal halves with anatomical reference points to guide the muscle detachment in a symmetrical way at an adequate depth. This method provides a guideline for the surgeon in determining the ideal plane during intramuscular dissection and gives predictable results with low complication rates. Intramuscular gluteoplasty with gluteal implants offers predictable, aesthetically pleasing results without contour irregularities and only a low incidence of major complications.

The purpose of this study was to investigate the incidence of sports injury and trend of incidence pattern of national judo athletes. The research method was analyzed based on the records of all injuries experienced by national judo athletes during training and competition for 9 years from 2008 to 2016. A total of 20,345 sports injuries requiring physical therapy were 10,768 (52.93%) for women, 9,577 (47.07%) for men, lower extremities 9,688 (47.62%), upper limbs 5,807 (28.54%), and trunk 4,850 (23.84%) and knee-related injuries (27.82%) occur more frequently than other injuries. Shoulders, feet and back were more frequent in male athletes, and ankle, neck and hand injuries were more common in female athletes. Using the binomial trend line, the trend of the decrease of sports injuries in each area was shown. However, infrequent injuries such as hands and hips tend to increase gradually. The results of this study are expected to be used as a training program for judo athletes' sports injury and basic data.

Purpose : The purpose of this study was to determine the effects of hip adduction using a ball on the activation of the vastus medialis oblique (VMO) and the vastus lateralis (VL) during dynamic semisquat exercises. Methods : Twenty seven participants performed three repetitions of a double-leg semisquat and squeeze semisquat (semisquat with hip adduction using a ball) at $60^{\circ}$ knee flexion. The activation of the VMO and the VL was recorded at dominant leg during both semisquat exercises using surface electromyography (MP 100). EMG data were normalized to the maximal voluntary isometric contraction (MVIC) of the quadriceps produced during seated, isometric knee extension. Results : Results of paired t-test analyses revealed that there were no differences between activity of the VMO and the VL in both double-leg semisquat and squeeze semisquat. The activity of the VMO was significantly increased in squeeze semisquat whereas there was no difference in activity of the VL between double-leg semisquat and squeeze semisquat. Conclusion : Combining hip adduction using a ball with semisquat at $60^{\circ}$ knee flexion preferentially increases the activity of the VMO. We can conclude that semisquat at $60^{\circ}$ knee flexion with hip adduction using a ball selectively recruits the VMO. Rehabilitation for quadricep imbalance should consider these findings when selecting exercises which could preferentially activate the VMO.

This study aims to establish measures to prevent emotional abuse by analyzing court precedents related to emotional abuse at daycare centers of Korea. For this, ten precedents of first trial and four precedents of appellate trial related to emotional abuse were analyzed in depth. In the results of study, there were diverse types of emotional abuse at daycare centers such as assaulting(hitting head, face, and buttocks with hands and feet), throwing things, neglecting, forcefully feeding food, stopping mouth with handkerchief and wet tissue, skipping meals, and showing scary images. And the main issues of precedents included the matter of justifiable act as circumstances precluding wrongfulness, and the matter of applying the joint penal provision. Based on such results, the measures to prevent emotional abuse at daycare centers were suggested.

The purpose of this study was to suggest the skirt grading rule for different somatotypes. For this study 9 subjects were classified three types according to the shape of front hips such as diamond, standard, heart. Skirts pattern were made by Moonwha grading method for traditional grading rule. For each somatotypes, skirt pattern were graded by new grading rule. The sensory evaluations were practiced for appearance and function. At the result, comparing between the new grading rule and traditional grading rule, new grading rule was fitter than the traditional grading rule. And diamond type was distinctively better than the other somatotype at sensory evaluation appearance. For pattern making of diamond type it had better use the new grading rule that was considered the characteristics of body shape.

The purpose of this study is to provide a basic pattern to assist in the development of formal pants that reflect the physical characteristics of women with lower-body obesity. The subjects selected for this study were women in their 20s and 30s with a Rohrer index of 1.6 or higher, a waist circumference 78.5cm to 83.5cm, and a lower drop of at least 18cm. The experimental pants patterns were developed by varying the waist line position, the waist ease, the ease in the hip area, the crotch length, the front and rear crotch width, the leg width, and the total length. Data analysis was performed using the SPSS statistics program(version 18.0). To verify the difference, this study used a variance analysis and Duncan's test. The conclusions drawn by the study are as follows. To reflect the form element of an abdomen with fatty deposits, the waist circumference should have an ease of 2cm. The front waist result was W/4+0.5cm+0.75cm and the rear waist result was W/4-0.5cm+0.25cm. The hip circumference showed a total ease of 4.5cm. The front hip result was H/4+0.75cm and the rear hip result was H/4+1.5cm. The crotch width set to H/16-1cm and the applied rear crotch width was H/16+2cm. The rear hip area was given more ease to reflect the protrusion of the hip. Along the line extending from the knee area to the crotch line, the outer seam line was designed with a gradual S-shaped curve to accommodate the protrusion from the maximum thigh width.

The purpose of this study was to analyze the effects of Hatha Yoga exercise on serum leptin and metabolic syndrome factors in obese and menopausal middle-aged women. The subjects were 26 obese women divided into the Hatha Yoga exercise group (n=13), which trained for 16 weeks, and the Control group (n=13). Variables of body composition, serum leptin and metabolic syndrome factors were measured in all the subjects before and after the 16-week Hatha Yoga training. The results of the study in the Hatha Yoga group were as follows: body weight, % fat, BMI, WC, WHR and VFA had significantly decreased, but SMM had increased. HDL-C had significantly increased, but leptin, TC, TG, LDL-C, insulin, glucose and HOMA-IR had decreased. The main variables affecting changes in VFA were % body fat, BMI, WHR, TC, LDL-C, glucose, and HOMA-IR. Therefore, regular and continuous Hatha Yoga exercise was effective in improving body composition, visceral fat and serum lipids. Consequently, Hatha Yoga exercise will be effective in preventing cardiovascular disease caused by obesity in obesew and menopausal middle-age women.
