The present study analyzed the two hand backhand stroke motion of six female high school tennis players who won the championship at the National Athletic Meeting in 2006, and drew conclusions as follows. The open angle of the racket at the moment of impact was 90 degree without significant difference among the players, making a wide contact between the ball and the racket. The racket angle was 43 degree at take back and 91 at impact, showing a style of holding the racket rather upright in general. In back swing from the top to the impact, the shoulders and the hips turned by 97 degree and 40 degree, respectively. At the moment of impact, the height of the impact was 54%H, and the position of the impact was 10%H ahead of and 37%H left from the central axis of the body. The right hand made a continental grip and the left hand made a Western or semi Western grip. Through the entire swing motion, the grip angle of the left hand was smaller than that of the right hand, and those who maintained a large grip angle of the right hand at the moment of take back put the racket head slightly farther from the body. In the swing of the racket head from the lowest point to the impact, the vertical length of movement was 11%H and the horizontal length of movement was 60%H, quite long.

Lower body type of middle-aged(40 to 59) women was analyzed to develop body type-specific slacks. The analysis has four factors. Factor one is hip and leg type. Factor two is lower body height and length. Factor three is waist type, and factor four is hip length. By conducting a cluster analysis with scores of four factors, it came to have three types of classifications. Type one is a rectangular-shaped slim type. Women of this type have a high and lengthy lower body and middle-length hip. They have thin and small legs, their lower body is the longest, and the smallest with small curve among three types. Type two is the diamond-shaped obese type. They have a high and long lower body and legs are medium they are the most obese type. Type three is the large, trapezoidal-shaped, slightly overweight type. They have the longest and the biggest leg and hip. But the length and height of the lower body is the shortest among the three, and the hip is small. Legs are the thickest and shortest. The hip is big compared with the waist and is the longest. They have big hips and thick legs.

This study analyzed the body shape of adult women aged 20 to 59 with a waist and hip circumference difference of 22.00 cm or more to characterize the lower body shape of women with slender waist. The researchers analyzed the data using SPSS 26.0. Among the lower body measurements of women with slender waists, the waist circumference was 70.79 cm and the hip circumference was 95.25 cm, with a difference of 24.56 cm between the waist and hip circumferences. We categorized the components of a slender waist body type into four factors: lower body horizontal, lower body vertical, lower calf horizontal, and hip and crotch length. We categorized women with slender waists into four body types: slender long crane legs, short thick lamb legs, short thin ladder legs, and thick long pole legs. In their twenties, many people have slender, long-legged lower body, but as they age, they are more likely to have thicker lower bodies and short, thin ankles. Body types with slender waist had larger proportions of abdominal and hip dimensions in the width, circumference, and thickness categories based on waist dimensions than those with average or thick waists.

The focus of this research was concerned with studying lower body type for Korean adult males. To understand the features of men's lower body required to organize an optimal sizing system for men's tight-fit slacks, information from the measuring values based on research on the physical standard of the nation(l997) were summarized; in addition, a factor analysis and a cluster analysis among multivariate analyses were performed. In terms of the need for appropriate fit in motorcycle wear, basic lower body parts applying to each item had to be taken into consideration to enhance sizing suitability. In the case of the length of the lower limbs, the inclusion of protectors plays an important role in affecting sizing. The factors related to the lower body were defined as follows: Factor 1 was the vertical dimension of the lower body, Factor 2 was the horizontal dimension of waist and hip, Factor 3 was the horizontal dimension of the lower limbs, Factor 4 was the length of hips, and Factor 5 was the ankle height. The lower body part was also divided into 3 clusters. Cluster 1 referred to the smallest stature and skeleton structure among the 3 body types. Cluster 2 represented the biggest stature, with a thin lower limbs body type. Cluster 3 represented a medium stature but with a large skeleton structure of lower limbs, a muscular type. In conclusion, Cluster 2 appeared most in the 20s age groups, but Cluster 3 appeared most in each of the 30s, 40's, and 50's age groups.

The purpose of this study is to grasp the inconvenience and problems with caregivers' uniforms and preferred designs by examining the wearing conditions of these uniforms in medical welfare facilities for the aged. To attain this purpose, a questionnaire was completed by direct observation and by interviewing caregivers in specialized hospitals for the aged and those engaged in nursing and then a preliminary examination was carried out. The questionnaire was given to 228 caregivers. Following are the results of this research. It was found that the caregivers in medical welfare facilities for the aged were women in their 50s, wearing primarily a size 77 uniform. It was revealed that when the caregivers bathe patients, they usually get wet from the knees to the bottom part of their pants and many of them (61.2%) change both their tops and pants after giving a bath. The caregivers said that every part of the tops of existing uniforms, except the armpits, were a little large or too long. It turned out that the area of the armpits, the front buttons, crotch, hip area, and knees are mostly the areas that readily wear out in the uniforms. It was reported that the uncomfortable parts in the uniforms a.e the armpits, shoulders, and the front adjusting parts of the tops and the hips, thighs, and the crotches of the pants. The material for the uniforms have problems in ventilation, fluffing, absorption of sweat, and permeation of odor.

The purpose of this study is to analyze the characteristics of older women's torso shapes. The data was collected from the 7th Size Korea, which featured 453 women between the ages of 70-85. A factor analysis was performed of 31 indices, including seventeen based on height and length measurements, eight based on circumference measurements, and six based on torso flattening. The torso shape was determined from seven factors: torso flatness ratio, shape of the side upper torso, vertical size of upper torso, silhouette of the torso, silhouette of the bust and abdomen, shape of the hip, and the vertical size of the back of upper torso. The torso shapes of older women were classified into three types based on the results of the factor analysis. Type 1 is called the large rectangle type. They have the lowest degree of forward bend in the torso, the largest vertical and horizontal size, a round body shape, and the upper torso is gently curved. Type 2 is called the inverted triangle type. They also have a round body shape, but the abdominal size is relatively small compared to the size of the bust, and also have an open and drooping bust, and the biggest degree of forward bend in the torso. Type 3 is called the square type. They are characterized by drooping hips, the smallest vertical and horizontal sizes, and the gentlest curve of the torso.

The purpose of this research is to understand the physiological characteristics of muscular men between the ages of 20 and 34 years who are distinct from the general population due to their muscular development, and to categorize them according to upper body somatotypes. This research was conducted in order to provide basic data necessary for developing clothing products for muscular men. The research method and results were as follows: 1. The study carried out factor analysis with the body measuring value of 168 muscular men according to the body classification method of Sheldon and Heath-Carter. The study materialized muscular men's lower body types statistically by carrying out cluster analysis, regarding scores of each factor extracted from the factor analysis as an independent variable. The study also carried out discriminant analysis with the results of cluster analysis classified so that morphological characters of each type were remarkably distinguished. 2. As the results of factor analysis, the study set up number of factors as three. Factor 1 occupied 38.149% of the total variables as a size factor of the lower body. Factor 2 occupied 20.417% of the total variables as a height and length factor of the lower body. Factor 3 occupied 8.466% of the total variables as a length factor of the hip. 3. The study classified the lower body type into three types and the characteristics by each type were as follows. Type 1 was a group with the best developed muscle in the lower of the body, considering that a size of their lower bodies was the largest. Type 2 was well-balanced muscular males though a size of the lower body was smaller than other types. This type didn't have fatness of the abdomen and large hips. Type 3 was a body type that the length from the waist to the hip was long. 4. As the results of carrying out discriminant analysis to distinguish muscular men's lower body types, the discriminant accuracy was 86.3% over all in the lower bodies.

Objective To replace camera-based three-dimensional motion analyzers which are widely used to analyze body movements and gait but are also costly and require a large dedicated space, this study evaluates the validity and reliability of inertial measurement unit (IMU)-based systems by analyzing their spatio-temporal and kinematic measurement parameters. Methods The investigation was conducted in three separate hospitals with three healthy participants. IMUs were attached to the abdomen as well as the thigh, shank, and foot of both legs of each participant. Each participant then completed a 10-m gait course 10 times. During each gait cycle, the hips, knees, and ankle joints were observed from the sagittal, frontal, and transverse planes. The experiments were conducted with both a camera-based system and an IMU-based system. The measured gait analysis data were evaluated for validity and reliability using root mean square error (RMSE) and intraclass correlation coefficient (ICC) analyses. Results The differences between the RMSE values of the two systems determined through kinematic parameters ranged from a minimum of 1.83 to a maximum of 3.98 with a tolerance close to 1%. The results of this study also confirmed the reliability of the IMU-based system, and all of the variables showed a statistically high ICC. Conclusion These results confirmed that IMU-based systems can reliably replace camera-based systems for clinical body motion and gait analyses.

(K)Hanbok, which is Korea's traditional clothing, differs from the Chinese Hanfu or Japanese Kimono. This study aims to understand the fundamental differences between (K)Hanbok and Hanfu. The Goryeo Dynasty (K)Hanbok, which was particularly popular in China, was established because the Ming Dynasty Hanfu and Chinese fashion were considerably influenced by the 'Koryo Yang'. Firstly, while (K)Hanbok is bulky, Hanfu of the Han Dynasty is characterized by forming a slim silhouette. Due to the climate of the Northern Hemisphere, (K)Hanbok shows a rich silhouette comprising multiple layers of inner pants and a pleated skirt over a voluminous underskirt. On the other hand, the Han's Hanfu creates a straight silhouette in the form of a wrap, revealing the contours of the body. The pleated skirt of the (K)Hanbok can use six to twelve width fabrics, depending on the social position; however, the Hanfu of the Han is a skirt without any pleats. Secondly, the clothing patterns, which have various shapes, are totally different in how they are made and sewn. The Korean (K)Hanbok is a two-piece separate, whereas the Chinese Hanfu style is a one-piece with a skirt. The short length of the (K)Hanbok jacket has a Sup which is cut and pasted allowing the front closure to overlap. Nevertheless, the Hanfu of the Han does not have this Sup because it is of a wrap-around, one-piece style and has an exceptionally large front, and wraps around at the waist which extends to the sides. Thirdly, the (K)Hanbok jacket has separate string Gorums for fastening, and an additional belt around the waist; however, in the case of Gorum, it is unnecessary for a wrapping style of Hanfu. Fourthly, Koreans as an agricultural horse-riding people, basically wore the trousers attached a comfortable gusset, while the Chinese Hanfu had no pants, but the Chinese wore Gaedanggo pants which exposed the hips, inevitably during the Warring States period.
