The purpose of this study was to classify the torso shape based on abdominal protrusion caused by changes in the physical characteristics of middle-aged women. This study analyzed 3D shape data of 401 females ranging in age from 40 to 59 years who participated in the 6th Size Korea project. Based on the Size Korea 3D measurement standard, 27 additional items such as height, protrusion, and angle were measured in the 3D scan data. Nine factors were extracted from the analysis of constituent factors of the torso: "vertical size of torso," "flatness and protrusion of abdomen," "torso front extrusion," "upper body height," "bust size and flatness," "size of belly and angle of lower abdomen," "hip length," "hip flatness," and "horizontal size of bust." As a result of the cluster analysis using these nine factors, the torsos of middle-aged women were classified into three types. Type 1 has upper abdominal deposition with a small and long upper body and an advanced abdomen; type 2 has lower abdominal deposition with a small and short torso and a small belly and hip flexion; and type 3 has central abdominal deposition with a big and long torso, large breasts, and protruding abdo¬men front. The middle-aged women were mostly distributed in Type 2. The above results will be useful as basic data for the development of clothing with improved fit to accommodate the changed physical characteristics of middle-aged women.

This study develops a coverall design for the body shape and movement of infants. This research analyzed these processes: 1. The current coverall styles preferred for infants. 2. The appropriate products for the real size, body shape, movement, and fit of infants. 3. The observations of the 6 months to 9 months movement and development of infants. 4. The design and creation of a new coverall base in this study, and to check the suitable test the developed coverall design for the infant. The result of this study are: A coverall for infants that lie or crawl on the floor must avoid opening in the center front and a gore has to be added at the crotch of the pants for the better movement of infants. These ways provide infants a neat appearance and easy movement. The test of developed designs shows that the developed coverall design covers the size gap of the trunk loop according to the growth of the infant and the movement of the legs; in addition it provides a positive aesthetic effect. The waistline in the developed coverall (a waistline that should exist lower than the body waistline of the infant) can reduce seam stress because the pressure of the seam line can be absorbed in a dipper. It is one of the suitable design points for infants lying prone all day long in this study.

This study was to investigate the relationship between time spent on lunch and degree of obesity, eating habits in culinary college male students. This survey was conducted using questionnaires for 106 male students in a Hongseung-located culinary college. Over 16 minutes of time spent on lunch group had significantly lower body weights, obesity degrees and body mass index (BMI) and tended to have lower body fat % than the other groups. It suggests that shorter time spent on lunch is related with lower body weight, obesity degree and BMI. Those who ate the meal prepared by mother had longer time spent on lunch. The shorter times spent on lunch group recognized their body shape was lean, the longer time spent on lunch group recognized the overweight or obesity significantly. The shorter time spent on lunch group tended to eat the cooked rice in the gug and recognized that they were not healthy. Those who had diseases in the past tended to have shorter time spent on lunch. The more they chewed cooked rice and then longer time spent on lunch they had, they recognized their eating speed was not significantly speedy. The shorter time spent on lunch they had, the fewer fruits and salty foods they ate significantly. This study suggests that more chewing time. slower eating speed and longer time spent on eatmg lunch is very related with lowering weight, BMI, body fat % and obesity degrees, so male college students should be educated to have correct eating habits.

A humanoid is a robot with its overall appearance based on that of the human body. When the humanoid moves or walks, dynamic forces act on the body structure. Although the humanoid keeps the balance by using a precise control, the dynamic forces generate unexpected deformation or vibration and cause difficulties on the control. Generally, the structure of the humanoid is designed by the designer's experience and intuition. Then the structure can be excessively heavy or fragile. A humanoid design scenario for a systematic design is proposed to reduce the weight of the structure while sufficient strength is kept. Lower parts of the humanoid are selected to apply the proposed design scenario. Multi-body dynamics is employed to calculate the external dynamic forces on the parts and structural optimization is carried out to design the lower parts. Because structural optimization using dynamic forces directly is fairly difficult, linear dynamic response structural optimization using equivalent static loads is utilized. Topology and shape optimizations are adopted for two steps of initial and detailed designs, respectively. Various commercial software systems are used for analysis and optimization. Improved designs are obtained and the design results are discussed.

The purpose of this study is to produce slacks pattern for pregnant women in the mid or second half period of their pregnancy according to the development figure of the body shell from a follow-up measurement. We here would like to produce slacks pattern for pregnant women constructed to fit better with their individual property in their figure and to help maintain the shape and beauty of the lower half of body and would compare it with two manufactured slacks pattern. The results of the study were as follows; 1. As the pregnancy proceeds, the height of natural-waist line went up spontaneously due to the projection of abdominal region, therefore, it was given darts at the front zipper part so that they could maintain a nice figure and to avoid possibility of feeling oppressed. To acquire a slimmer outfit, we made of the slacks-bottom narrower than the width at the knee line, and it worked out. 2. Sensory evaluation for appearance: According to the statistical of the result of 19items on the questionaire, all items showed significant difference(a$\leq$0.01) between the new and A(bunka) B(Kim's pattern) method slacks pattern, with the new pattern having higher scores. The new drafting method proved to be better fitted, to fit the shape of bodies properly and to get a visual effect to look slim.

This study was to investigate the effects of the body fat $\%$ on life styles and self-recognition of health conditions in hotel culinary college students. This survey was conducted using the questionnaires for 144 students (110 males, 34 female) in Hongseung-located college. More exercise time and less frequency of alcoholic beverage they intake, lowered their body fat $\%$. Males did stronger exercise and had lower body fat $\%$ than females. The stronger exercise they did, the lower body fat $\%$ they had, and were more satisfied with their present weight. Since they had more alcoholic beverage, they smoked more. Less smoking, more abdominal obesity they were. The less satisfaction with their body weights, the higher body fat $\%$ they had. The obese less were content with their weights. More recognition of obese shape, higher body fat $\%$ they had and abdominal obesity they were. Female had higher body fat $\%$ and were more abdominal obesity, did weak action, less smoke and weak exercise than male. Higher body fat $\%$ they had, more abdominal obesity they were. The more part time jobs they had, they did not smoke or were not satisfied with their body weights. Female students in culinary arts division had higher body fat $\%$ and were dissatisfied with their body weights and did less exercise or subnormal exercises.

The purpose of this study was to provide basic informations for educating juveniles on desirable body image recognition by examining their body image recognition and comparing and finding problems according to gender and body mass index (BMI) in middle school students. The average age of the subjects was 15, their average height was 162.5 cm, their average weight was 53.5 kg, and their average BMI was $20.1\;kg/m^2$. Male students wanted to gain weight and female students wanted to lose weight. As for body shape, female students thought that they were fat more often than male students. Also the more overweight the students were, the higher their concerns and experiences toward weight control. Among weight control methods, exercise scored highest in all BMI groups. Over 80% of the respondents answered that their weight control effort were not systematic such as via professional counseling. As for the frequency of eating breakfast and dinner in female students, the more a student was overweight, the lower their frequency of eating breakfast and dinner. Many respondents answered that a typical meal time was '10~20 minutes'. The average eating habit score for all subjects was 38.0. The eating habit scores of male students were significantly higher than those of female students, and there were no significant differences among BMI groups. Eating habit score of 'I have more than two meals with rice everyday' in female overweight group was significantly higher than those of other two groups. These results indicate that the female students' degree of preference for a slim body shape were higher than those of male students. In addition, weight control by students is not systematic through professional counseling; instead they attempt to control their weight by themselves such as a meal skip, which lead to potential danger that they may lose weight carelessly. Therefore, correct body image recognition is greatly needed, and families and schools should make ceaseless efforts to help students properly control their weight and have correct eating attitudes.
