Purpose: The purpose of this study was to investigate the influences of body mass index (BMI), mindfulness and self-esteem on reported body image among university students. Methods: Data were collected through questionnaires from 266 students and were analyzed using descriptive statistics, t-test, ANOVA, Scheffe's test, Pearson's correlation coefficients and Stepwise multiple regression analysis with SPSS/WIN 19.0 program. Results: As defined by body mass index, the sample was divided into an underweight group was 88.7%, a normal weight group was 10.5%, and an overweight group was 0.8%. The levels of body image depended on family income, personality, and BMI. The body image was significantly correlated with BMI, mindfulness, and self-esteem. The influential factors affecting body image were self-esteem, BMI, family income and personality, which explained about 34.6% of the variance. Conclusion: The results of this study indicate that nursing intervention are needed to improve body image, and that such variables should be carefully considered in intervention for university students.

PURPOSE : The purpose of this study was to determine whether tredmill exercise increases pulmonary function and decreases body mass index of the 20s obesity. METHOD : Thirty obesity in their 20s were randomly assigned to on experimental group (n=15) or control group (n=15). Over the course of four weeks, the experimental group participated in tredmill exercise for 30 minutes three times per week and the control group participated in auto-med exercise for 30 minutes three times per week. Subjects were assessed pre-test and post-test by measurement of pulmonary function (tidal volume, inspiration reserve volume, expiratory reserve volume, vital capacity) and body mass index. RESULT : Our findings show that the experimental group had significant difference in expiratory reserve volume and vital capacity and body mass index (p<.05). In the comparison of the two groups, the experimental group had higher pulmonary function and lower body mass index than the control group. CONCLUSION : In this study, the experimental group showed greater improvement in pulmonary function than the control group, which indicates that the tredmill exercise is effective at increasing the pulmonary function and body mass index 20s obesity.

The rigid body properties of a structure may be estimated easily if the mass-line of the structure could be taken exactly. However, the exact mass-line cannot be obtained experimentally. In the past years, the modal analysis for which the structure is mounted on the flexible supporter is frequently used to acquire the mass-line. Unfortunately, it is difficult not only to mount the structure but also to decouple the coupled 6 dof mode. If the structure is pended by very long and flexible rope to act free, the rigid-body modes influenced by the rope will be eliminated and the improved mass-line will be obtained. In this paper, the method using the mass-line of F.R.F. for rigid body in free-condition is suggested. The robustness of the suggested method was tested and verified numerically. The experimental results also showed a good agreement with the true value.

The purpose of this study is to reveal the effect of electrical stimulation of body composition in obese person. Subjects were 30s to 40s aged healthy workers(2004. 3. 8~4. 17) in the S general Hospital in Suwon and they were brought to manage obesity. Subjects were divided into control group(Female<0.85, Male<0.90) and study group(Female>0.85, Male>0.90) by WHR(waist-hip ratio) that is measured by Automatic body composition analyzer(InBody 3.0). And we divided the study group with randomized methods into group A(n=8) and group B(n=8). Then we compared and analyzed the change of muscle mass, body fat, abdominal girth, WHR, BMI(body mass index) after application of electrical stimulation, three times a week, for 30 minutes in each session with 50 Hz of pulse frequency, $20\;{\mu}s$ or $250\;{\mu}s$ of pulse duration. There was statistically meaningful decrement of body fat(p<0.05) and abdominal girth(p<0.05) but not of body weight, muscle mass, WHR and BMI in the control group after application of electrical stimulation with 50 Hz, $20\;{\mu}s$. There were meaningful change of abdominal girth(p<0.05), WHR(p<0.05) and BMI(p<0.05), but not of body weight, muscle mass and body fat after application of electrical stimulation with 50 Hz, $20\;{\mu}s$ in group A. We applied electrical stimulation with 50 Hz, $250\;{\mu}s$ in group B, then there were meaningful change of body weight(p<0.05), body fat(p<0.01), abdominal girth(p<0.01), WHR(p<0.05) and BMI(p<0.01) but not of muscle mass only. Consequently, the pulse duration is the main parameter of electrical stimulation that affect the body composition of obese person in this study and if we combined the diet control to reduce blood components we could have better result. So it would be more effective to manage localized obesity(in abdomen, thigh, upper arm, etc.) if you apply electrical stimulation considering the pulse duration.

BACKGROUNDS/OBJECTIVES: Cancer treatment may lead to significant body composition changes and affect growth and disease outcomes in pediatric cancer patients. This prospective study aimed to evaluate short- and long-term body compositions changes focused on body fat during the first year of cancer treatment in children. SUBJECTS/METHODS: A prospective study was conducted in 30 pediatric cancer patients (19 hematologic malignancies and 11 solid tumors) and 30 age- and sex-matched healthy controls. Anthropometric measurements and body composition analysis using whole body dual energy X-ray absorptiometry were performed at baseline and 1, 6, and 12 month(s) of cancer treatment. Kruskal-Wallis tests, Wilcoxon paired t tests, and generalized estimation equation (GEE) were applied for statistical analysis. RESULTS: At baseline, no differences in weight, height, body mass index, abdominal circumferences, body fat, and fat-free mass were observed between 30 controls and 30 pediatric cancer patients. Total fat mass (P < 0.001) and body fat percentage (P = 0.002) increased significantly during the first month, but no changes were observed from 1 to 12 months; however, no changes in the total mass were observed during the first year of cancer treatment. Meanwhile, the total fat-free mass decreased during the first month (P = 0.008) and recovered between 6 and 12 months of follow-up (P < 0.001). According to GEE analysis, there was a significant upward trend in body fat percentage during the first year, especially the first month, of cancer treatment in children with hematologic malignancies, but not in those with solid tumors. CONCLUSIONS: Our results indicate that cancer treatment is related to significant body composition changes and rapid body fat gain, particularly during the first month after initiating cancer treatment, in children with hematologic malignancies. Therefore, individualized dietary strategies to prevent excessive fat gain are needed in pediatric cancer patients for better outcomes.

To simulate solid dynamics,a we must com-pute the mass, the center of mass, and the products of inertia about the axes of the body of interest. These mass property computations must be continuously re-peated for certain simulations with rigid bodies or as the shape of the body changes. We introduce a GPU-friendly algorithm to approximate the mass properties for an arbitrarily shaped body. Our algorithm converts the necessary volume integrals into surface integrals on a projected plane. It then maps the plane into a frame-buffer in order to perform the surface integrals rapidly on the GPU. To deal with non-convex shapes, we use a depth-peeling algorithm. Our approach is image-based; hence, it is not restricted by the mathematical or geometric representation of the body, which means that it can efficiently compute the mass properties of any object that can be rendered on the graphics hardware. We compare the speed and accuracy of our algorithm with an analytic algorithm, and demonstrate it in a hydrostatic buoyancy simulation for real-time applications, such as interactive games.

Objectives : The purpose of this study was to investigate the influence of modified fasting therapy using fermented herbal medicine on the changes of body compositions. Methods : This study was carried out on 11 patients who carried out modified fasting therapy using fermented herbal medicine. They went through reducing food intakes period(7 days), fasting period(10~14 days) and refeeding period(10~14 days). Body compositions(weight, BMI(body mass index), skeletal muscle mass, body fat mass, percent body fat, basal metabolic rate, waist-hip ratio, visceral fat area) were measured at each state. And then the data was analyzed. Results : 1. The weight and BMI decreased during the reducing food intakes period and the fasting period, and increased during the refeeding period. But the weight and BMI decreased during the fasting therapy period, as a whole. 2. The skeletal muscle mass decreased during the fasting period and increased during the refeeding period. As the final outcome, for the whole fasting therapy period, decrease of skeletal muscle mass didn't show significance. The body fat mass and percent body fat decreased during the reducing food intakes period, the fasting period and the refeeding period. 3. The basal metabolic rate decreased during the fasting period and increased during the refeeding period. As the final outcome, for the whole fasting therapy period, decrease of basal metabolic rate didn't show significance. 4. The waist-hip ratio decreased during the fasting period and the refeeding period. The visceral fat area decreased during the fasting period and refeeding period. Conclusions : Results from this investigation showed that modified fasting therapy using fermented herbal medicine have positive effects on changes of body compositions. This results are expected to compensate the defects of existing fasting therapy.

When considering the effects of whole-body vertical vibration, it is valuable to have an understanding of the mechanical characteristics (mechanical impedance and apparent mass) of the body. This paper addresses experimental results carried out to investigate the characteristics of apparent masses fer 41 Korean. The apparent masses of the seated human body in vertical direction were measured during different experimental conditions, such as vibration excitation level (0.5-2 ms$\^$-2/ r.m.s). frequency range (1-50Hz), and upper body posture (relaxed, normal and backrest-upright). We showed the average of all subjects and all conditions and compared the results with ISO5982/DIS (2000).

In this study, we examined chewing frequency, eating rates, and food consumption volume according to the body mass index of male and female college students. Twenty-five male college students were divided into a normal weight male group (<23 body mass index, n=14) and an obese male group (${\geq}23$ body mass index, n=11). Twenty-five female college students were divided into a normal weight female group (<23 body mass index, n=21) and an obese female group (${\geq}23$ body mass index, n=4). Subjects were provided with abundant fried rice and allowed to consume it at their own pace. Chewing frequency, total mealtime, rate of eating, consumption volume, calorie intake, and the amount of one bite were measured. There were no significant differences in chewing frequency, total mealtime, rate of eating, consumption volume, calorie intake, and the amount of one bite between the normal and obese male groups. There were also no significant differences in chewing frequency, consumption volume, calorie intake, and the amount of one bite between the normal and obese female groups. However, the obese female group had a significantly shorter mealtime and significantly higher eating rate compared with the normal group. Thus, our study suggests that females who eat a meal for a longer time may reduce their food intake, consequently inducing body weight loss.

Purpose: The aim of this study was to examine BMI, body fat mass, percent body fat, waist-hip ratio, soft lean mass, skeletal muscle mass, and fat free mass, and to determine the association between dietary behavior and exercise and body composition among students at women's colleges, and decide on the relationships among them. Method: This study employed a cross-sectional study design and a convenient sampling method. Ultimately, a total of 404 students participated in the study, which was conducted from September 1 to December 22, 2009. Measurements administered were comprised of dietary behavior and a questionnaire on exercise. The SPSS Win 18.0 statistics program was used for analysis of final data. Results: Major findings are as follows: 9.9% of participants showed a high BMI, and more than 56% and 38% of participants showed a high percent body fat and waist-hip ratio, respectively. Dietary behavior showed a significant negative association with percent body fat (r=-0.110, p=0.027) and waist-hip ratio (r=-0.118, p=0.018). Compared with the non-regular exercise group, the regular exercise group showed a high level of soft, lean mass (t=4.15, p<0.001), skeletal muscle mass (t=3.13, p=0.002), and fat free mass (t=4.00, p<0.001). Conclusion: For maintenance of proper body composition, health promotion programs for management of dietary behavior and regular exercise for students at women's colleges should be developed.
