  • Body fat proportion is a major issue in health. The prevalence of obesity in childhood has been increasing on thesedays. A series of indirect estimates of body fat have been developed. There are hydrodensitometry, BIA and anthropometry equation for body fat. Hydrodensitometry has been regarded as a common criterion method. BIA made it possible to analyze body fat mass more related to hydrodensitometry than anthropometry. The purpose of this unvestigation were to compare body fat and other body composition between boys & girls and to know which anthropometry equation for body fat was most closely associated with BIA in boys & girls respectively. The subjects were 148 4th grade elementary school students(male:70, female:78). They underwent BIA(InBody 3.0, Biospace Korea)to determine body fat and other body composition. Anthropometric measurements were taken of height, weight, skinfolds and circumferences. The results obtained are summarized as follow: 1) Weight, BMI and Rohrer index were $39.9{\pm}7.2kg$, $20.5{\pm}8.0$, $138.2{\pm}17.0$ for boys and $35.9{\pm}6.7kg$, $18.2{\pm}2.6$, $96.6{\pm}13.6$ for girls. 2) Total body fat and percent body fat determined by BIA were $10.3{\pm}4.3kg$, $25.4{\pm}6.6%$ for the boys group and $9.3{\pm}3.8kg$, $25.1{\pm}6.0%$ for girls. 3) Mean triceps skinfold thickness was $20.5{\pm}6.1mm$ in boys, $17.0{\pm}5.1mm$ in girls and mean WHR was $0.88{\pm}0.4$ in bodys, $0.82{\pm}0.4$ in female and the values were significantly different by sex. 4) Correlational nanlyses showed that estimation of body fat by BIA measurement seemed to be closely associated with Rohere index(boys r=0.854, girls r=0.909). Kim's equation was highly correlated with the body fat in girls(r=0.910) but less correlated in boys(r=0.710). We need to develop specific anthropometric equations based on age and sex to determine body fat for children.

  • With a view to developing male dress forms for educational purposes, human body measurement was made for male adults in their twenties residing in Busan, Korea. Based on the results, the following conclusion was obtained: 1. Comparison d the measurement in Busan and the data of the 5th Korean physical dimensions(Size Korea) In the comparison of the Busan male adults in their 20s with national physical dimensions(Size Korea) by way of the Mollison relational deviation line, all the 28 items revealed differences less than 0.7. As the Busan sample reflects the body type d the average Korean men in their 20s, Busan's measurement results can be safely used as the data for dress form development. 2. Results of front body type classification According to the factor analysis, seven factors of the front body type were produced to explain 77.25%. The factors were shoulder angles, waist height, hip shapes, chest shapes, proportion of body(chest, waist, hip)width to shoulder width and so on. Cluster analysis brought about three somatotype groups. First, the body type with the least differences in hip-waist width, shoulder-waist with, and hip angles (24,23% in appearance) was named Type H. Second, the body type with the most chest-waist width and hip angles (38.66% in appearance) was called Type Sam X Third, the body type with the greatest shoulder-chest width, shoulder-hip width, and shoulder angles (37.11% in appearance) was termed Type Y.

  • This research aims at developing the dress form for the aged women based on their body shapes using the three-dimensional body scan data with the body shape categorization(according to the previous research). To accomplish this goal, the sample group of representative body shape of the 50% of median was selected by using the high frequency proportion range of each type of body shape of the aged women, and the sample group of representative body shape of each type was averaged in a three-dimensional way by using the morphing method of a three-dimension reverse-engineered software. RP in the form of torso was produced based on the shape data of the final model and the data was formed into an actual object, by which an aged women's dress form model was drawn out. The differences of the girth of the bust, hip and waist between the developed dress form model and the existing dress form model were examined. The result showed that the developed dress form had a bigger size of waist girth than that of bust and hip girth, compared to the existing dress form, which shows that it reflects the aged women's tendency of abdomen obesity, so it's expected to be more proper for the human bodies of the targeted age group than the existing dress form. These research results may help design the clothing suitable for the body shape of the aged women so that their demand for the clothing of good fit will be satisfied in the future.

  • Obesity is considered as a primary health problem over the past century in line with life environmental changes. It is mainly associated with increased risk of numerous chronic diseases which may significantly reduce health-related quality of life. Therefore, efforts to reduce weight should be performed. This study suggested a novel approach to reduce body fat by applying external stimulation which is micro-current stimulation (MCS). In this clinical study, we evaluated the potential effects of MCS for reduction of abdominal fat and weight loss. Prior to the clinical test, computational simulation was conducted to find the proper MCS conditions that allow externally applied stimulation to reach the internal fat section from the external skin. Particularly, the clinical study evaluated the unilateral effects of MCS for body fat loss and lipolysis without any additional limitations such as physical exercise and dietary therapy. The results showed that whole body fat, waist circumferences, and abdominal fat are gradually decreased after intervention in proportion to the time. From the results, we can estimate that MCS can be effective on the body fat loss by activation of lipolysis in human adipose.
