The purpose of this paper is to determine the percentage of body fat by measurement of skin-fold thickness of the triceps and the subscapular area to investigate the relationship between the daily energy intake and expenditure among obese women and nonobese women based on the percentage of body fat and age. This survey included 422 females in Cheju. 1) The age distribution of the 422 females surveyed was : 26.8% were in their 20's, 20.6% in their 30's, 21.3% in their 40's, 19.0% in their 50's and 12.3% were above 60 years of age. The 422 females consisted consisted of 78% housewives, 12.8% college student and 9.2% single working women. 2) The average height and weight of the surveyed women were respecitively 159.0$\pm$4.2cm and 56.0$\pm$7.2kg, the percentage of body fat of the surveyed women was 24.8$\pm$9.8%, and the BMI of those surveyed was 22.7$\pm$2.7. If higher than 30% body fat was defined as being obese, 15.6% of the surveyed women were assessed to be obese. 3) Total daily food consumption and energy intake of the group of women aged 60 and older was significantly small. Food consumption and nutrient intake of obese women was greater than that of the nonobese group, but not significant. Carbohydrate intake of the obese group in their 40's was significantly higher than the nonobese group. Total food consumption, energy and carbohydrate intake of the obese group in their 50's was significantly higher than the nonobese group. Vegetable intake of the obese group in their 60's and older was significantly higher than the nonobese group. 4) The total time of physiological activity of women aged 60 and older was significantly higher than for the other age groups and the total work time was significantly lower. The total work time of women in their 20's was not lower than the other groups. Considering the low energy expenditure of physical activity for women in their 20's, they appeared to have light activity. However, there was not a significant difference in the physical activity time among middle aged women groups(from 30 to 50). The entire energy expenditure of the obese group was greater than the nonobese group. However, the energy expenditure per body weight in the obese group was significantly less than that of the nonobese group in terms of the basal metabolic rate in consideration of the fat free mass. 5) There was a positive correlation between the percentage of body fat and the factors of age, sleeping time, total time of physiological activity, housework time, time spent watching TV, energy expenditure, energy intake, carbohydrate and cereal consumption. On the other hand, the percentage of body fat was negatively correlated with energy expenditure per body weight based on the basal metabolic rate in consideration of the free mass.

This study was conducted to determine the effects of chromium-methionine (CrMet) supplementation at various levels on obesity index, body fat, and serum glucose, insulin and leptin in rats. Forty male Sprague-Dawley rats were randomly assigned to one of four dietary groups and fed AIN-76 semi-purified basal diets supplemented with 0, 300, 600 or 1200 ppb Cr from CrMet. After 4 weeks on the respective diets, the rats were killed and serum glucose, insulin and leptin concentrations were determined. The CrMet supplementation did not affect weight gain, feed intake or feed efficiency ratio, fasting glucose, insulin or leptin levels among treatment groups. Although final body weight in all treatments were not significantly different, naso-anal length was longer in the 1200 ppb CrMet group than those of control or other groups (p<0.05). The lowest obesity index and body fat were observed in the 1200 ppb dietary group (p<0.05). The obesity index of the rats fed 1200 ppb supplemental CrMet was lower than in the other groups. These results suggest that CrMet supplementation results in a significant decrease in obesity index, possibly by decreasing the body fat that corresponded to increasing CrMet dosage.

It is known that displacements, velocities and accelerations of the tractor- trailer type vehicle system in shock & vibration analysis by the flexible-multi-body dynamics including the flexibility of structure are bigger and more repetitive than them by the rigid-multi-body dynamics, and it is necessary to prove above results by the experimental field test. Therefore, in this paper, theoretical analysis by the flexible-multi-body dynamics and experimental field test for a tractor-trailer type vehicle system are conducted and their results are compared with each other. Because of unexpected metal contact and impact in the air coupler part in the field test, some accelerations measured from the experimental field test are bigger than them analyzed from the theoretical analysis, but most accelerations are well coincide with each other in the amplitudes and trends. Thus more refined dynamic analytical models for some special type vehicle systems will be possible in the future.

The purpose of this study is to identify the expression methods of uncanny images shown in contemporary fashion through the visual expression methods of plastic arts. The study results are as following. First, there is a concept-forming element of 'The return of Repressed', which is a psychological mechanism for generating uncanny sets to the component of 'repression' and 'return'. 'Repression' herein consisted of 'unconsciousness', 'the other', and 'anxiety', while the return was composed of 'trauma' and 'repetition compulsion'. Second, there are visual expression methods of the uncanny in contemporary art. The subject of 'repressed things' was expressed as grotesque and having a terrible look. 'Fragmented body' was analyzed as 'dismantling' by mutilation, 'combination' placing cut body parts in other places, and 'damage' suffering from an illness or accident. 'Fear of death' was shown as 'anatomy' reminiscent of death and 'iconography of death' meaning return of the dead. 'Post-human' was a surrealistic being such as a monster and mechanized human, and was analyzed as 'gene variation' and 'cyborg'. Third, the methods of visual expression of the uncanny reflected on contemporary fashion was analyzed as 'fragmented body', 'fear of death', and 'post-human'. 'Fragmented body' appeared as the object reminiscent of the fragmented body, 'dismantling and combination of the body', and 'damage of the body' through the distortion of the clothing construction principle. 'Fear of death' visualized the characteristic elements of the subject reminiscent of death as 'iconography of death' and 'symbolic object of death' through the motif. 'Post-human' was the description of the subject beyond the body's function and form, and was shown as 'gene variation' and 'cyborg'.

The purpose of this study was to interpret consistently a phenomenon in Korean Women's ideal body with analyzing the change of the body of winners in beauty contests such as Miss Korea and Super Model. The method of this study was to investigate the objective data of body size of winners in beauty contests. The meanings in the change of Korean Women's ideal body are as follows. First, the body have got the commercial value with the start of Miss Korea contest and maximized its commercial purpose with the introduction of Super Model contest. While Miss Korea contestants are evaluated by their body, character, intelligence altogether, Super Model contestants are evaluated by body itself than other factors. So the body of Super Model is accepted as the highly value added commodity. Second, a tall height as a natural gift anions characteristic of the ideal body have become the significant factor of the myth of social and commercial success.

Pulmonary function test has been know to be greatly affected by body indices, such as sex, age, height, body weight, body surface area (BSA) and body mass index (BMI), so hat this study was focused to see the relationship between body index and flow-volume curves. Subjects were 156 (male 90, female 66) and they were examined for pulmonary function test in terms of body index and correlation/multiple regression analysis of flow-volume curves at Presbyterian Medical Center from March to August, 2009. The followings results after analyzing the correlation between body index and flow-volume curves. Although flow-volume curve FEF25-75% showed close correlation with age, body weight, and body surface area, but not with body mass index. In addition, multiple regression analysis was performed to see how each body index affects flow-volume curve FEF25-75%, and FEF25-75% dispersion was explained as 74.5% with age only, 94.2% with age and height, and 96% with age, height, and sex. Therefore, sex, age and height that are mainly used for predictive formular of pulmonary function test and nomogram were important factors for pulmonary function test itself, and further study must be done for other body index.

The purpose of this study is first, to see through the aesthetic essence of the clothing as art, through theoretical consideration of cultural feature and body style in Postmodern Feminism. Also, this study will examine the aesthetic value in artistic meaning regarding a Deformational body image in visual an. Second, this study will analysis the formative character of Modern Art to wear which expressed unfixed body style, followed by the change of Postmodern Feminity, as a Deformation image. This character will be categorized by Expansion, Grotesque, Pleasure, and Virtuality. The following is the result of this study. Expansion expressed in modern Art to wear created intentional structure of the form, and intentionally presented refusal of body existence through disembodied. Grotesque expressed refusal and deviation of women's ideal body style, which is defined by mannish discourse, very grotesquely. Pleasure pleasantly presented free emotion through an intentional transformation like distortion or imbalance of the body By paradoxically reproducing women's virtual body as other unfixed female identity was expressed visually through virtuality to embody post-gender.

This study was carried out with 505(243 boys and 262 girls in the Sungnam area) high school students to investigate the effects of eating behavior and anthropometric variables of weight and height on excercise performance. General characteristics about subjects and eating behavior were surveyed by questionnaire, anthropometric data were collected using two methods. The weight and height of subjects in 1996 were measured, but the same data in 1995 were collected from health records of each student. Body fat content of subjects was measured by BIA(Body Impedance Analysis). The grades of exercise performance, which were evaluated by physical education teachers were collected from records of a physical strength test score of each subject. From these, the following result were found. Groups with different eating behaviors such as skipping meals, overeating, food preference for a specific food(milk, carbonated drink etc.) were significantly different in their weight and height and body fat contents. The growth rate of height in first and second grade boys was significantly higher than that for grade boys. The amount of weight gain from second grade to third grade was significantly more than that of other grades both for boys and girls. The mean of BMI was $21.66\pm{2.95}$ in boy, $21.50\pm{2.62}$ in girls. The percentage of body fat was $24.91\pm{6.55%}$ in boy $34.73\pm{4.88%}$ in girls. Amounts of body fat were significantly increased in third grade. The group with higher fat content and the higher BMI group had lower values of physical strength. And the ability to exercises perform decreased significantly by promotion of grade. The other variables such as degree of concern about weight control and preference of exercise, and frequencies of exercise per week were significant factors in body fat content and physical strength. As a countermeasure for these problems, nutrition and health education must be developed for adolescents and a practical, proper physical activity guidance campaign for them is necessary.

Wave-body interaction is simulated using a developed code based on the flux-difference splitting scheme for immiscible and incompressible fluids and the hybrid Cartesian/immersed boundary method. A free surface is captured as a moving contact discontinuity within a fluid domain and an approximated Riemann solver is used to estimate the inviscid flux across the discontinuity. Immersed boundary nodes are identified inside an instantaneous fluid domain near a moving body, then dependent variables are reconstructed at those immersed boundary nodes based on interpolation along local normal lines to the boundary. Free surface flows around an oscillating cylinder are simulated and the computed wave elevations are compared with other reported results. The generation of a solitary wave by a moving wave-maker is simulated and the time histories of wave elevations at two different points are compared with other results. The developed code is applied to simulate body motion of an elastically mounted circular cylinder as a solitary wave passes the body. The force acting on an elastically mounted cylinder is compared with the force acting on a fixed cylinder. Grid independency of the computed body motion is established based on a comparison of results using three different-size grids.

The aim of the present investigation was to see whether an anabolic steroid, nandrolone phenylpropionate (NPP), exerts protienanabolic effects under such adverse nutritional conditions as protein deficiency and protein-energy malnutrition in male rats. feeding on a low-protein (8% casein) diet resulted in a marked reduction in body weight gain that was associated with reductions in body protein and protein content of gastrocnemius muscle. Administration of NPP (4 mg/kg body weight) did not alter muscle and body protein depletion induced by a low-protein diet. 50% food restriction caused reductions in body protein and in protein content of gastrocnemius muscle. These reductions were partially prevented by NPP (4 mg/kg body weight). Food restriction did not affect plasma concentration of corticosterone, insulin, or tetosterone plus dihydrotestosterone. On the other hand, neither plasma concentration of corticosterone nor insulin were affected by NPP. The present results show that anabolic steroids do not express anabolic effects under conditions of protein deficiency, but in protein-energy malnutrition, anabolic steroids exert their anabolic effects even in male rats.
