The purpose of this study was to investigate kinematic coordination and control of lower segments in skill process. For the investigation, we examined the difference of resultant linear velocity of segments and angle vs angle graph. Novice subjects were 9 male middle school students who has never been experienced a taekwondo and expert subjects were 7 university taekwondo players. We analyzed kinematic variables of Dollyochagi motion through videographical analysis and the conclusion were as follows. 1. Examining the graph of novice subjects' maximal resultant linear velocity of the thigh, shank, and foot segment, as it gets closer to the end of the training, the maximal resultant linear velocity in each segment increased. Statistical analysis showed the following results; thigh segment caused the increase of speed, using the trunk segment's momentum in the latter term of learning, while the shank segment utilized the momentum of the adjacent proximal segment at the beginning of learning, and the foot segment in the middle of learning. 2. Until the point where the knee joint angle is minimum, as the novice group learn the skill, the flexion of knee and hip joints has changed into the form of coordination pattern in phase. On the other hand, the expert group showed continual coordination pattern in phase that the movement sequences were smooth. From the knee joint maximal flexion to impact timing, all novice and expert groups showed coordination pattern out of phase. 3. From the knee joint maximal flexion to impact timing, the ankle joint was fixed and the knee joint was extended to all the novice stages and expert subjects.

The purpose of this study is to provide basic materials for amateur golf players or golf maniacs to learn desirable iron swing motions. This study compared and analyzed the swing motions of iron clubs(3, 6, 9) by using 3-D in three elite golf players. 1. There was no a great difference in the total of swing time by club and the time by phase was nearly similar. 2. There was no a difference in the change in a head location at address and impact by club. 3. The angle change in a right knee joint was similar by club except the difference according to the length of the club. 4. There was a subtle difference in hip rotation angle by club. 5. In each club, the same rotation angle of shoulder joint at address and impact motions contributed to accurate swing, and the maintenance of more than $90^{\circ}$ of shoulder rotation angle in top swing increased swing rotation. 6. Although subtle, the forward angle of upper body was increased with a shorter club. $30-36^{\circ}$ of forward angle of upper body was maintained at address, top swing, and impact motions.

Obesity is an independent risk factor fur coronary artery disease in the postmenopausal women, which may be mediated by alteration of blood lipid metabolism. We are aimed to evaluate the effects of low energy diet, restriction of high fat foods and exercise education on weight, fat mass and blood lipid profile. Fifteen postmenopausal obese women were studied. Subjects received detailed advice about how to achieve a reduction of weight by a low-energy diet (1,200kcal), restriction of high fat food and increased exercise in every 4 wks during 8 wk. To evaluate the effectiveness for education programs, dietary fat habit and daily nutrient intakes, exercise were tested before and after intervention. Anthropometry, computerized tomography, and blood lipid profile were assessed before and after intervention. According to the nutrition education, energy intake (from 1776.1 ${\pm}$ 28.2 kcal to 1268.7 ${\pm}$ 115.2 kcal, p < 0.001) and percent of energy from fat (21.9%, p < 0.01) were significantly decreased. However, the index of nutritional quality was over 1.0. On the contrary, exercise (from 341.3 ${\pm}$ 222.1 kcal to 569.4 ${\pm}$ 309.8 kcal, p < 0.05) was increased and dietary fat habit scores (from 30.8 ${\pm}$ 5.2 to 36.1 ${\pm}$ 3.0, p < 0.01) were improved. Also, body weight (4.2%, p < 0.001), BMI (4.5%, p < 0.001), body fat mass (3.4%, p < 0.05) and waist to hip ratio (1.1%, p < 0.05) were decreased. Among abdominal fat, visceral fat (26.1%, p < 0.05) and subcutaneous fat (14.8%, p < 0.01) were decreased. But there was no difference in visceral fat to subcutaneous fat ratio. We observed HDL-cholesterol increase (11.7%, p < 0.05), triglyceride reduction(14.8%, p < 0.05) and atherogenic index improvement (from 2.7 ${\pm}$ 0.7 to 2.3 ${\pm}$ 0.7, p < 0.05) However, there was no change in LDL-cholesterol and total cholesterol. Theses results showed that low energy diet, restriction of high fat foods and exercise education could result in reduction of body weight, fat mass, visceral and subcutaneous fat, and in improvement of blood lipid profile in the postmenopausal obese women.

The usage of basic bodice blocks at men's apparel companies is investigated and the domestic and international men's upper bodice blocks are compared to find directions of research on development of bodice basic blocks. The following conclusions are found in this study. 1. The survey shows that basic bodice blocks are not used at men's apparel companies although all the respondents have good knowledge on bodice basic blocks. They responded that basic bodice blocks for representative body figures of each age category or of each country would help comparative studies on domestic and international basic bodice blocks and development of exporting apparel products. Also, they expected the utilization of men's basic bodice blocks both as education materials and in studies of design, of body figures, and of basic blocks for industry. 2. The comparative study on men's bodice blocks shows that waist circumference, hip circumference, neck circumference, height, and shoulder length, in addition to the minimal essential size items such as chest circumference and center back length, are used in most basic bodice blocks. The size formulae of each basic block are compared to find how the sizes are determined. For center back length, either measured back length or a certain proportion of height is used. For front and back interscyes, chest circumference is used in most basic bodice blocks. Either measured size, or a certain proportion of height or chest circumference is used for back height. The averaged ease allowances of basic bodice blocks are 3.2 cm for chest circumference, 10.8 cm for waist circumference, 1.2 cm for front interscye, 0.1 cm for back interscye, 0.2cm for shoulder length, and 0 cm for center back length. However, body blocks for different types of clothes have different ease allowances. Shirt basic blocks have ease allowances of 6.1 cm for chest circumference, 13.7 cm for waist circumference, 1.4 cm for front interscye, 0.6 cm for back interscye, 1.2 cm for shoulder length, and 1.8 cm for center back length. On the other hand, jacket basic blocks have ease allowances of 8.8 cm for chest circumference, 16 cm for waist circumference, 1.1 cm for front interscye, 1.4 cm for back interscye, 1.1 cm for shoulder length, and 0.8 cm for center back length.

As a result of research, the character of the general dress-costumes from the late 17th century to the early 18th century in Genre Paintings of DuSeo Yun and YoungSeok Cho is as follows. Firstly young women wore braided hair at the back of head and married women wore hair in the style of Unjeun-mori with Gache. The length of Jeogori (Korean traditional jacket) covered waistor shortened to waist length. The width of Jeongori was suitable, because side-seam line was straight or oblique as it comes into inner line. The width of Git was enough and Mokpan-git (shape of board) and Kal-kit (shape of knife) appeared, and sometimes used other color fabric. Sleeve was narrow and ostly folded up. Chima (Korean traditional skirt) used darker color fabric than Jeogori and the width of Chima was narrow and its length was short. Sokbaji (Korean traditional underpants) shown below were narrow and its end narrower. They were barefoot or they wore Hye (Korean traditional shoes) after putting on Beoseon (Korean traditional socks). Secondly general man's hair tie a topknot (sangtu) and put on headdres, 'Bang-lip', 'Mang-geon', hairband, 'Tang-geon' on head. The length of Jeogori became shorter from the line which covered hip to the line which covered waist. The width of Jeogori was suitable and sometimes it had a slit of side-seam line. The width of Git (neckand) was wide and the length of Git was long. 'Kal-git'appeared and it used other color fabric. The shape of sleeve was straight and narrow. They folded up their sleeves. They folded up their sleeves. They folded up their slack that look like 'Jam-bang-i'and the width of slacks was not suitable, and it was narrow. Baji (Korean traditional pants) were with or without knot, worn 'Hangjeon'(ankle band). They were barefoot and wore 'Hye'or 'Jipsin'(Korean traditional straw shoes). Thirdly a person of high birth or a low-ranked official put 'Yu-geon', 'Mang-geon', 'Gat', 'Tang-geon', 'Bok-du', 'Bok-geon', 'Whi-hang'on their head on a topknot. They wore 'Po (Shim-ui, Jick-ryeong'Jung-chi-mak, Do-po, etc)'on Baji and Jeogori. 'Po'was long and wide, it knot with 'Se-jo-dae'(string belt) or 'Po-baek-dae'(band belt). It had a slit of sideline and 'Mu'which had or had not or which were hard to confirm. The shape of sleeve was straight or very wide and its length was long. The width of Baji was wide and knotted with 'Hangjeon'and wore'Beoseon'and 'Hye'. Fourthly child's hair was short or knotted to the back of the head. The length of Jeogori reached waist line and its width was wide. It had a 'Jeogori'which had s slit of sideline. The shape of sleeve was 'Tong-su'(straight), and the length of sleeve was diverse. They put 'Baeja'on 'Jeogori'. The width of Baji was not wide. They wore them straight without or with knot, 'Hangjeon'. They were barefoot or put on 'Jipsin'.

Housewives' perception on obesity related variables to their family members according to the composition of children in the family was explored. Ninety housewives responded to a questionnaire consisted of sociodemographic informations, body weight perception, eating behaviors perception, and physical activity level for herself as well as her family. They were categorized into three groups based on child composition of the family; boys only (BO), girls only (GO), and boys and girls (BG) families. Boys in BO showed higher value of height, weight, and WHR than girls in GO (p <.05), while no differences were noticed in BMI and the waist girth between the groups. Mothers of BO perceived boys were active while mother of GO did girls were inactive (p <.05). Girls in GO ate meals less regularly than boys in BO and girls in BG. In general, housewives' perception on body weight of family members was relied on BMI and waist girth. As mother's BMI increased, the boy's BMI in BO was also elevated (p <.05), but not in others. Mothers' perception on caloric intake and activity encouragement were not accounted for morphological characteristics. Results suggest that housewives perceived obesity related variables differently based on the composition of children of the family.

This study was performed to investigate the effects of very low calorie diet (VLCD) using meal replacements that contain the wild grass extracts that are consisted of mainly Samul-tang ingredients on weight reduction and health promotion in the obese women (BMI$\geq$25 kg/$m^2$) for four weeks. Fifty six premenopausal women participated in this experiment. Each subject was either classified as part of the control group (C group, n=28) that consumed 3 regular meals a day or the meal replacement group (MR group, n=28) that consumed 1 regular meal and 2 meal replacements within 600 kcal/day. Anthropometric measurements, body composition, health related factors, and psychological factors were assessed before (the initial) and after (the 4$^{th}$ week) the study. Obesity was significantly decreased after the diet intervention. Anthropometric measurements such as weight, waist and hip circumference, and BMI and body composition such as body fat, and fat mass were significantly decreased in all groups after the diet intervention. Anthropometric measurements and body composition of the MR group were significantly decreased more than those of the C group. Serum total cholesterol was significantly decreased in the MR groups but not in the C group and serum triglyceride concentration was significantly decreased in all groups after the diet intervention. All the biochemical measurements were within normal ranges after the diet intervention. Psychological factors such as stress and depression were significantly decreased in two groups after the diet intervention. Therefore, VLCD using meal replacements is very effective for weight reduction in the obese premenopausal women.

The purpose of this study was to evaluate the effects of low calorie meal substitute and weight control preparation containing dietary fibers, ${\alpha}$-amylase inhibitor and hydroxycitrate on the reduction of body weight and visceral fat in obese women. Sixteen pre-menoposal healthy women (age: 20∼50 y, body mass index >25) who were living in the Daejeon area participated in this study. We replaced one meal of the subject with low calorie meal substitute and fed the weight control preparation twice a day for 9 weeks. Anthropometric indices, body composition, dietary intake and stool movements were investigated every 3 weeks during the dietary intervention. The blood was collected before and after the dietary intervention. Results are as follows: 1) The subjects' body weight, body fat, BMI, waist, hip and abdominal adipose tissue decreased gradually and significantly between 3rd and 9th week after intervention. 2) The levels of fasting blood glucose, triglyceride and cholesterol, the indicators of liver dysfunction such as activities of ALT, AST and ALP, and bilirubin level were within a normal range and not affected significantly by dietary intervention. 3) Hemoglobin levels increased significantly and blood urea nitrogen level decreased. 4) Their stool movement was improved 5) Compared with the baseline values, calorie intake decreased by 17.5∼21.9% and the intakes of vitamin A, vitamin B2, folate, Ca, Fe, and Zn were below 80% of Korean RDA. In conclusion, the intake of low calorie meal substitute and weight control preparation could be effective in reduction of body weight and fat mass, improving the stool movement and the general physical symptoms.

This study was to investigate the effects of a silk peptide, and prune and raspberry mixture on the body fat, serum lipid composition and fat distribution in Korean women during the time they received these supplements. During the 4 month period of this research (June to October, 2002), 75 women (average age 22.9 yr) were selected as subjects. Their nutrient intake was investigated by use of a questionnaire and the 24-hour recall method. Antropometric assessments of the subjects were investigated by using the SBIA Method (Segmental Bioimpedance Assay, Inbody 3.0). The results were as follows: their mean body weight was 59.3 kg, their mean body height was 161.7 cm and their mean Basal Metabolic Indices (BMI) was 22.7. The status of their dietary fiber intake significantly increased (p < 0.05) after use of the supplements. Their body fat significantly decreased following the $3^{rd}$ stage of supplementation (p < 0.05), and their percent of body fat signiflcantly decreased after supplementation (p < 0.05). Their triceps and suprailiac circumference significantly decreased following the $3^{rd}$ stage of supplementation (p < 0.05). Their waist circumferences and waist-hip ratios (WHR) significantly decreased after both the $2^{nd}$and $3^{rd}$ stage of supplementation (p < 0.05). Their total cholesterol significantly decreased following the $3^{rd}$ stage of supplementation, as compared to their baseline results and those obtained following the 1$^{st}$ stage of supplementation (p < 0.05). Their LDL-cholesterol and LDL / HDL ratios significantly decreased following the $3^{rd}$ stage of supplementation, as compared to their baseline results and those obtained following the 1$^{st}$ stage of supplementation (p < 0.05). Their 4-HNE and total antioxidant statuses significantly decreased following the $2^{nd}$ and $3^{rd}$stage of supplementation, as compared to their baseline results and those obtained following the $1^{st}$ stage of supplementation (p <0.05). Their $2^{nd}$ stage supplementation results were significantly negatively correlated with their triceps measurements and WHR (p < 0.05). Their $3^{rd}$stage supplementation results were significantly negatively correlated with their anterior thigh measurements (p < 0.05). The above results show that prune, raspberry, silk peptide and dietary fiber supplementation to a routine diet improves body fat distribution, total cholesterol, and triglyceride levels. The decrease of abdominal fat and WHR were especially noteworthy. This implies a decrease of risk factors. (Korean J Community Nutrition 8(3) : 356~367, 2003)003)

As late as middle of 1980s, what was referred to as new model cars consisted, on the premise of a standardized packaging layout, principally of the endeavor to transform their style images by changing little by little the form of layouts almosts similar to or with larger bodies than those of the old model ones. Afterwards even in the period of competition of engeineering and mechanical body styles for reducing fuel cost and improving comfortability in riding, the standardized packaging layout did not change visibly, simply trying to ameliorating commercialism through high output and high efficacy on the engineering part. Today the sudden prevalent motorization in every walk of life has brought about the development of the car industry, thus producing surplus supply and technical standardization. This phenomenon of technical standardization leads the concept of the renovation of car design to a way quite different from that of the past and so may be said to be confronted with an era that requires genuine-sense car design in a way. It seems that interior design plans are of much more importance than external shapes. This is because the effort for enhancing comfortability to keep car passengers' needs of transportation is one of the essences of car design. The objective of this study consists in inquiring into how to plan motorcar interior design, an essential prerequisite in determining the external or of a car, obtaining data needed via analysis of interior design plans of the car models that have won favorable criticism from consumers, thus contributing to the use of the data obtained for reference in car design activities in a genuine sense.
