To determine the parameters to be considered when designing lower-body apparel, we analyzed the lower-body figures of adult women in their early 20s from Shanghai, China, using 3-dimensional whole body scanner. Thirty-nine lower-body-related measurements were used to analyze the figures of 210 Chinese women. Obesity and height of the lower body, length from waist to crotch, shape of abdomen, and leg bone length were analyzed. Factor analysis was performed and the results were classified into three clusters. The first cluster describes the obesity of the lower body, the second denotes small hip measurement, and the third describes slim and long legs. This is the first study to quantify figure analysis of the lower body of Chinese women using 3-dimensional body measurements. The findings of this study will provide concrete information regarding crotch width, crotch length, inseam, outseam, waist slope, etc., for designing trouser patterns for Chinese adult women.

본 연구는 한우의 체형과 체중이 일령에 따라 어떻게 변화하며, 선발형질인 도체형질과의 상관 또한 체중 및 체형의 변화에 따라 어떠한 형태로 변화하는지 알아보기 위하여 실시하였다. 분석에 이용한 형질은 체중, 체형 및 도체형질을 포함하여 모두 17가지 형질이며 거세우 161두의 자료를 이용하였다. 성장곡선 추정은 logistic 모형을 이용하였고, 추정한 모수를 토대로 변곡일령 및 변곡일령에서의 특성을 다시 계산하였다. 각 형질에 대한 성장곡선 모수를 분석한 결과 좌골폭은 조숙성, 흉위는 만숙성 형질인 것으로 나타났다. 등지방두께에 대한 흉심, 흉폭 및 요각폭의 순위상관계수는 6~24개월까지 꾸준히 증가하는 반면 다른 체형형질들은 18개월령 이후에 감소하는 것으로 나타났다. 본 연구는 표현형 자료에 대한 분석만이 이뤄졌으나, 한우 성장 단계에 따른 유전적 변화를 살펴보기 위해 유전모수 추정과 같은 추가적인 연구가 이뤄진다면 체형형질을 한우개량에 충분히 이용이 가능할 것으로 생각된다.

This study was conducted to investigate the physical characteristics and risk factors for hyperchol-esterolemia (HC) in Korean. 344 adult men who took the annual health check-ups at D or J hospitals were participated in this cross-sectional study. The subjects were grouped by plasma total cholesterol level in to three groups: normal cholesterolemic (n=139) borderline hypercholesterolemic(n=93) and hypercholesterolemic (n=112) groups. The data of height weight and plasma cholesterol level were col-lected from medical records. Body circumferences(midarm, waist, hip, and thight) skinfold thicknesses (biceps, triceps, subcostal, abdomen, and suprailic), and body composition (fat mass and fat free mass) were measured. Body mass index (BMI) height/weight ratio (HWR) waist/hip circumference ratio (WHR) waist/ thigh circumference ratio (WTR) central skinfold thickenss (CSF) and peripheral skin-fold thickness were calculated. The subjects with HC had significantly higher weight BMI waist cir-cumference skinfold thickness and body fat mass than those of the normal subjects. The relative and attributable risks on HC were 1.61 and 0.17 for obesity (BMI$\geq$25) 1,30 and 0.11 for upper body obesity (WTR$\geq$1.30) and 1.54 and 0.18 for central body obesity (CSF$\geq$95.7). Plasma total cholesterol level was positively correlated with several antropometric parameters: BMI (p<0.001) weight(p<0.001) waist circumference(p<0.001) and skinfold thickness of abdomen (p<0.001) spraillic (p<0.01) triceps(p<0.01) subcostal (p<0.01) and biceps (p<0.05) In conclusion the major influencing factors to plasma cholesterol level was BMI. Among the each physical parameters the circumference of waist the skinfol-d thickness of abdomen and the percentage of body fat were closely related to plasma cholesterol level. The important risk factor for hypercholesterolemia was obesity specially upper body obesity and central body obesity.

Physical parameters of milk cow were measured to design and build RMS(Robotic Milking System) with a tape-measurer and body parameter measurer. The parameters are very important variables to design an RMS. For the working zone space of an RMS manipulator and the movement blunting of milk cow, an interval frame was installed on the stall bottom, and then cow's behavioral reactions were tested. The results from this study is summarized as follow. 1. On the general physical condition measurement, the maximum, minimum and average body length of cow which is related to the space that the manipulator could work into the RMS were 175cm, 144cm, and 163cm respectively. It appeared that the average distance between bottom and chest was 60cm. 2. The average length between fore teats, fore and hind teats and hind teats were 178mm, 150mm and 95mm respectively. It appeared that the average length between bottom and teat attachments was 544mm, and the average length between fore teats and tail-end was 331mm. 3. Although a cow kept a some extent length between hind legs for milking, it looked a stable pose. However, the cow kept a some extent distance between front legs for milking, it looked a unstable pose. Based on results of this test, an interval frame of stall bottom should be installed around the position which was located at its hind legs.

PURPOSE: The purpose of the present study was to investigate the effects of whole body vibration exercise on balance, muscle strength and falls efficacy in the elderly. METHODS: In this blinded randomized allocation study, 27 elderly were assigned to a whole-body vibration exercise group (n=14), consisting of 25 min structured exercises for 2 days per week for 6 weeks and a control group (n=13) performing the same program without vibration. At baseline and after the 6-week intervention, balance was measured using the Korean version of the Berg balance scale (K-BBS), timed up and go (TUG) test and functional reach test (FRT). Muscle strength was determined using the 30-s chair stand test (CST). Fear of falling was assessed using the Korean version of falls efficacy scale (K-FES). Paired t-test and independent t-test were used for within and between group comparisons, respectively. RESULTS: After the intervention, the experimental group showed significantly higher changes in all the parameters (K-BBS score, TUG test, CST, K-FES score) (p<.05) compared with the control group. However, there was no significant change in all parameters in the control group (p>.05). CONCLUSION: The whole-body vibration exercise program may be helpful to improve balance, mobility, muscle performance and fear of falling in the elderly.

Most of the numerical and experimental studies on supercavitating flows are focused on the cavitator only. However, the partial cavity growing into the supercavity is affected by the shape of the body placed behind the cavitator. In this paper, we develope a numerical method which is based on the boundary element method to predict supercavitating flow around three-dimensional axisymmetric bodies. We estimate the influence of the body shape on the supercavity growth. Here, we consider various parameters of the body such as cavitator shape, shoulder length and body diameter, and compare the results with the case of the cavitator only. In summary, it is found that the body may impede the cavity growth, the shoulder mainly affects the cavity length, and the supercavity occurring in the cone type cavitator is strongly influenced rather than that of the disk type cavitator.

Six lactating crossbred cows and six Murrah buffaloes, maintained under similar conditions of feeding and management were studied for body composition by the antipyrine dilution technique. Measurements were made at the start of the experiment when the animals had completed about 50 days in lactation and thereafter at monthly intervals up to 90 days of the experimental period. The percent body water estimates in both species at different time intervals did not change significantly. Percent body fat and protein content also remained unchanged. The correlation coefficient between body composition parameters and various hormones (growth hormone, insulin, $T_3$ and $T_4$) were generally low and non-significant. It was concluded that body composition studies using body water are not sufficiently sensitive to predict changes in body composition of lactating cows and buffaloes and/or the changes in body composition during lactation are not very drastic.

Bisphenol A (BPA) is a monomer widely used in the manufacturing polycarbonate plastics or epoxy resin, and xenobiotics recently known as endocrine disrupting chemical. In this paper, to assess the effects of bisphenol A on immunopathological parameters (body weight, organ weight, hematological parameters, cellularity and surface marker) in mice, ICR female mice were orally exposed to BPA dissolved in olive oil as concentrations of 100, 500, 1000 ㎎/㎏/day b.w. 5 days a week for 30 days (subacute exposure). Liver - and kidney weight was significantly increased as dose-dependent manner, but body- , spleen- and thymus- weight didn't changed. In hematological parameters, WBC and MCHC were lowered but HCT and MCV were siginificantly enhanced. There was no significant differences in peritoneal macrophages number of the mice exposed to BPA. However, number of splenocytes of spleen, CD3/sup +/ and CD4/sup +/ cell in splenocytes, CD4/sup +/ and CD8/sup +/ cell in thymocytes were decreased at the mice subacutely exposed to BPA. In addition, BPA decreased expression of B7-1 and B7-2 on macrophages. Therefore, these results showed BPA may affect hematological parameters, cellularity and surface marker of immunocytes.

Dent resistance is an important characteristic to avoid damage on automotive outer panels. From a practical point of view, dents can be caused in a number of ways. Considering doors as an example, denting can occur from stone impacts or from the careless opening of an adjacently parked vehicle door. Denting can occur where the door surface is smooth and may not have sufficient curvature to resist dent. These exterior body parts are designed to improve dent resistance using a combination of work hardening and bake hardening. In brief, dent is affected by the shape of the parts and the material properties such as yield strength, strain and thickness. In this work, forming of door outer panel is investigated by Taguchi method. Main parameters are yield strength, thickness, blank size, blank holding force and so on. For the given value of design parameters, forming analysis of the thirty six cases are carried out according to L18 orthogonal array. After comparing the performance by simple conversion of simulation results into dent resistance, the final suggestion of the forming parameters is verified for the best improvement of dent resistance.
