Objectives : The limited number of studies to date have mainly focused on the effect of obesity on the characteristics of plantar foot pressures. This study is designed to find the correlation between plantar pressure and obese index. Methods : This study assessed the body composition of 30 obese women using bioelectrical impidence analysis and Gaitview AFA-50. The static and dynamic plantar pressure was determined from electronic footprints captured using a capacitive pressure distribution platform during standing and walking. The data were analysed by independent t-test and Pearson Correlation. Results : Positive correlations were noted between body weight, body mass index(BMI), waist circumference(WC), waist-hip ratio(WHR) and difference of fore and rear plantar pressure. And negative correlations were noted between body weight, BMI, WC, WHR and difference of left and right plantar pressure. Conclusions : The findings of this pilot study suggest that body composition influences the waight distribution in overweight and obese subjects.

Sleeping is important activity in bedroom and it takes one third of our lifetime. The body pressure distribution on bed has been considered as one of the most important factors affecting sleeping comfort. The measurement contact pressure has been applied to design seat, mattress, shoes, etc., for prevention of pressure sores and improvement of products. This paper discusses the recognizing rule of sleeping posture using contact pressure. Subjects' ages are ranged from twenties to fifties. They include 29 males and 35 females. Body pressure distribution is measured in the state of stable bed when subject lies on his/her back, on his/her side and on his/her face. We made recognizing rules of sleeping posture through statistical analysis; ANOVA and regression analysis, qualitative analysis.

This study was intended to figure out the effects of the amount and the distribution of body fat on the risk fators of adult disease. Sixty-four male college students paticipatied in this study, whose to find out body fat distributions were classified on the basis of Waist/hip ratio(WHR) into three groups-upper body type(UBTM), intermediate body type (IBTM) and lower body type(LBTM). Various risk factors such as adiposity, body fat ammount, serum lipid amount and blood pressure and their intercorrelations were analyzed. The three bodys type groups showed significant differences each other in weight(P<0.001), WHR showed considerable correlations with BMI and the percentage of body fat. The frequency of obesity assessed by BMI$\geq$25 and body fat percentage were the highest in the UBTM of the three groups. Thus, we could conclude that the closer the body fat distribution is to the upper body type, the higher the BMI and body fat percentage. Waist/girth ratio(WTR, P<0.01) and BMI(P<0.05) were positively correlated with serum triglyceride levels, and % of body fat was positively correlated with both serum triglyceride (P<0.01) and serum total cholesterol(P<0.05) levels. WHR (P<0.05), BMI(P<0.01) and % of body fat(P<0.01) also showed positive correlations with systolic blood pressure. From the above results, we could conclude that body fat distribution was a good index reflecting adiposity and body fat amount and that blood and serum amount of triglyceride was highest in the upper body type group showing the highest frequency of obesity.

A finite element simulation model was developed for the performance optimization of a closed type air-cell mattress used for the ulcer prevention. An H-model with material properties of human flesh and kinematic joints were used for the calculation of the body contact pressure. The material property of rubber air-cell was evaluated by tensile test of standard specimen. We evaluated the body contact pressure distribution after laying human model on the inflated air-cell mattress. It was found that the body contact pressure was dependent on cell height. but hardly affected by the thickness of the rubber in a cell.

This study was intended to figure out the difference of the blood lipids, insulin and nutrients intake by fat distribution among the obese young male in Korean. Twenty-eight male college students participated in this study, whose to find out body fat distributions were classified on the basis of Waist /hip ratio (WHR) into three groups-upper body type (UBTM), intermediate body type(IBTM) and lower body type (LBTM). To conduct this study, anthropometric measurements , blood pressure, serum lipids and insulin levels, and daily nutrients intake were analized . The results are as follows : The three body type groups showed significant differences each other in waist circumference(p<0.05), WTR(p<0.001) and body fat percentage (p<0.05). Also they showed significant difference each other in the daily construction in the daily energy intake. But they did not show significant differences in the blood pressure, serum lipids and insulin levels. From the above results, we could concluded that the body fat distribution in obese the young men could affect nutrients intake pattern.

The purpose of this study was to investigate differences in body fat distribution between normal and obese subjects and the relationship between risk factors(fasting blood sugar, blood pressure. fasting serum lipids) and obesity. Measurements of height. weight, skinfold thickness. body circumference. percent body fat. blood pressure, fasting blood sugar and serum lipids were made and a dietary survey was performed on 120(Males 61. Females 59) adult subjects. 1) Among the female subjects, the obese group appeared to have significantly higher centrality of body fat than the normal group. Obese groups of both sexes appeared with higher blood pressure than normal groups. No differences in daily average nutrient intake, fasting blood sugar and fasting serum lipids concentrations were observed between obese and normal groups. 2) In males. the serum triglyceride concentration was observed to have a significantly positive correlation to body weight, body mass index and body circumference, additionally concentrations of total cholesterol and LDL-cholesterol were observed to have significantly positive correlations to the skinfold thickness. but the ratio of HDL-cholesterol/total cholesterol was observed to be significantly negatively correlated to the skinfold thickness. 3) In females. the obese group consumed about 47% of total energy intake at lunch. whereas the normal group consumed about 29% . The food habit score of males appeared to be negatively related to body weight, percent ideal body weight. But the food habit score of females appeared to be negatively related to percent body fat(r=-0.32, p<0.05) .

The contact pressure distribution between a rubber wiper blade and a glass windshield is a major factor for wiping performance. A modeling and simulation method has been developed to forecast the contact pressure distribution on a wiper blade. For modeling multi-body dynamics of an wiper linkage system and flexible nature of wiper blade, ADAMS and ADAMS/flex are employed. A simulation study has been also conducted to obtain contact pressure distribution. Comparison between simulation and measurement is provided to ensure fidelity of the model and the simulation method.

A girdle is a body-shaping article of clothing. The garment pressure of the girdle is considered an indispensable factor. The purpose of this study was to identify changes in body size and distribution of garment pressure after donning the girdle. The changes of body size and garment pressure were analyzed by body types. Korean women (n=19) in their 20s participated in the experiment. Their body types were classified according to four factors: the index value(hip girth-waist girth), and waist, hip, and thigh girths. The garment pressure was measured at 12 points. The results of this study showed that the hip and thigh girths were reduced mostly after donning the girdle. These values were 2.0~2.8cm and 1.7~2.3cm, respectively. The garment pressure was high at the waist band, the hip joint, and the gluteal furrow region at the back. The subjects whose waists, thighs, or hips were well developed showed great garment pressure in the hip area, but their hip girth decreased very little. The subjects with less developed or slim thighs or hips showed a slimming effect, with moderate pressure in the hip and thigh regions. These results show that the hip and thigh can be slimmed with moderate pressure by donning a thigh-length girdle. High garment pressure is not necessary for the girdle's body shaping effect. The hip area is hard to get body slimming effect with high garment pressure. The current girdle sizing system needs to be revised in order to lower garment pressure in the hip region. The researchers suggest using 3cm size intervals rather than 6cm size intervals for hip girth.

This study was undertaken to provide correct posture guidance and reference material for sports injury and injury prevention programs, by analyzing body alignment and plantar pressure distribution in high school baseball players. Totally, 32 subjects were enrolled for the study. Body alignment was measured from the trunk imbalance, kyphotic angle, lordotic angle, pelvic tilt, and pelvic torsion. Foot pressure was measured from the left maximum pressure, right maximum pressure, left weight, and right weight. The mean and standard deviation of the measured factors were calculated and tabulated, and the correlation between body alignment and foot pressure distribution was analyzed using Pearson's correlation analysis. All statistical significance levels were set at 0.05. Body alignment and foot pressure distribution show a positive correlation between the lordotic angle of lumbar spine and the left maximum pressure. There was no correlation between trunk imbalance, kyphotic angle, lordotic angle, pelvic tilt, pelvic torsion, and the left·right weight distribution and the left·right maximum pressure of each foot. Results of this study determined that the increase of the lordotic angle of lumbar spine results in more force on one side of the foot, thereby increasing the maximum pressure. We believe our data could be a reference for exercise programs on physical alignment and plantar pressure distribution of athletes.

The pressure distribution between human body and seat surface has been considered as an important factor affecting seating comfort. However, it is rare to find general guidelines of how to analyze these pressure patterms related to the seating comfort. In order to investigate the relationship between the pressure patterns and the subjective feeling of seating comfort, a high-resolution body pressure measurement system was adopted. The measured patterns showed that the clear distinctions between the comfortable seats. It was also possible to estimate the seating comfort based upon the analysis of the pressure patterns. The further research will be focused on finding out the relationship between physical seat design parameters and the seating discomfort.
