  • The flow field around a three dimensional minivan-like body has been simulated. This study solves 3-D unsteady incompressible Navier-Stokes equations on a non-orthogonal curvilinear coordinate system using second-order accurate schemes for the time derivatives, and third/second-order scheme for the spatial derivatives. The Marker-and-Cell concept is applied to efficiently solve continuity equation. The fourth -order artificial damping is added to the continuity equation for numerical stability. A H-H type multi-block grid system is generated around a three dimensional minivan-like body. Turbulent flows have been modeled by the Baldwin-Lomax turbulent model. The simulation shows three dimensional vortex-pair just behind body. And the flow separation is also observed the rear of the body. It has concluded that the results of present study properly agree with physical flow phenomena.

  • The pourpose of this study is to determine the exact size which can be the basic elements of the fashion design with the measurement of middle-aged women's body, and to grasp the peculiar tomato type of the middle-aged women by compacting each measurement and examing the change of body shape. Making 215 house wives about 40 to 55 years old the subject of this research, we measured the body size from June to August, 1994. After analyzing the data through the 43 item.; of the body measurement, grasping the characteristics of the tomato type, we classified three types of physical standard and looked into the element of body structure. The results were as follows; 1. The average Rohrer index of middle-aged women in Tas-gu is about 1.5 and they usually seem to be fat compared with other groups. 2. Age has much influence on the body change of middle-aged women. Especially around 45 years old, the body change showed remarkable. 3. When analyzing the elements of the body measurement, the biggest elements of middle -aged women's body structure are in the items of width, thickness and girth related to the expansion of body line. Therefore in the middle age, the thickness and the girth have more influence on the human body than the height and the length, so the items of thickness and girth is the most important factor in the somato type. 4. In the slim body and standard body, the thirst factor is the items of height and length related to vertical size and the second is the items of width and thickness and girth. In ice fat body the first factor is the items of width, thickness, girth and the second is those of height, length. Unlike other body shapes, the fat body has many factors, which shows that the fat body has much variation in each part in proportion to fatness.

  • This paper presents some of the efforts by the authors towards numerical prediction of springing of ships. A time-domain Higher Order Boundary Element Method (HOBEM) based on cubic shape function is first presented to solve a complete second-order problem in terms of wave steepness and ship motions in a consistent manner. In order to avoid high order derivatives on the body surfaces, e.g. mj-terms, a new formulation of the Boundary Value Problem in a body-fixed coordinate system has been proposed instead of traditional formulation in inertial coordinate system. The local steady flow effects on the unsteady waves are taken into account. Double-body flow is used as the basis flow which is an appropriate approximation for ships with moderate forward speed. This numerical model was used to estimate the complete second order wave excitation of springing of a displacement ship at constant forward speeds.

  • The characteristics of the demographics in Korea as it gets older are the increase of Elderly Women and continuous progress in urbanization. In this study, body shapes are classified as standard, obese, and tiny according to the previous studies based on the body shape characteristics and the body measurement of the Elderly Women. Based on the classification, we developed prototype of the panty for the Elderly Women to provide basic materials for the quality enhancement of the clothing of the increasing Elderly Women. The followings are the result of the study. 1. To categorize the body shapes of the Elderly Women focusing on the lower half, we grouped the target subjects using the nested approach by the average standard deviation and the factor analysis minimal diffusion method. Accordingly, type 1 and 2 had 36 members respectively and type 3 had 43 members. In this study, two Elderly Women subjects with standard body shape falling under the type 1 were selected as the subjects. 2. In the second trial evaluation for the prototype panty for the Elderly Women 32 items for appearance test and 3 items for functional test were evaluated. The scores in leg, sideline and hip were shown high and the balance between the parts was maintained very well. In the functional test, the panty used to be too tight for the leg curve but in the second trial it was improved, too. In each item, the second trial test showed better score than the first trial test. Conclusively, the most optimal panty prototype for the Elderly Women was proposed according to the trial test result.

  • Background The length of the second digit (the index finger) relative to the length of the fourth digit (the ring finger) is sexually dimorphic as males have a lower second to fourth digit ratio (2D:4D). There is evidence that sex differences in 2D:4D arise from in utero concentrations of sex steroids, with a low 2D:4D (male typical ratio) being positively related to prenatal testosterone, while a high 2D:4D (female typical ratio) is positively associated with prenatal oestrogen Objective To investigate possible associations between 2D:4D ratio and sexually dimorphic body composition Methods 2D:4D ratio, body mass index (BMI), waist circumference, waist-hip ratio (WHR), weight, and body fat percentage was measured from 46 men and 20 women Results Digit ratio was found to be significantly lower in men than in women. No significant correlation between 2D:4D ratio and body compositions was found for both men and women while digit ratio in obese men was significantly higher than normal weight men. Conclusion This finding dose not support the significant correlation between digit ratio and sexually dimorphic body composition. However digit ratio in obese men was significantly higher than normal weight men.

  • The author carried out this study to research the biological value of the protein fermented wheat bran. This study mainly devided into two parts. First part includes seven subgroups composed of five rats and second part fourteen subgroups composed of six rats each. In the first part of this study forty weanling male rats, aged 40${\pm}$5 days were fed by fermented wheat bran diet for seven weeks. In second part of this study 90 male weanling rats were fed by rice and soybean diet supplemented by fermented wheat bran. In the first part of this study food consumption rate of fermented group showed higher than standard group but the former group is lower than the later in the body weight gains. In the second part of this study, rice groups showed same trend of the result of the first part, but soybean groups did not go along with the result of rice group. In regard to body nitrogen retention rate, fermented wheat diet group showed higher than the standard group in the first part of this study. In the second part of this study rice diet groups revealed same result as that of the first part of this study but soybean diet did not give the same result in this respect. There was no significant difference in organ weight in all experimental groups but devided by 100 gram of body weight, the reverse is true in compare with body weight gains. Hematological investigation did not show the significance in both experimental and standard groups of the first and the second studies. It is conclusion of this study that rice which is inferior to soybean in protein quality, increases the rate of supplementary effect by fermented wheat bran in all respects of this study.

  • An Eulerian-Lagrangian method, so called immersed boundary method, is used for analysing viscous flow around arbitrary bodies, where governing equations are discretized on a regular grid by using a finite volume method. To improve the accuracy of flow near body boundaries, a second-order accurate interpolation scheme is used and a level-set based grid deformation method is presented to construct the adaptive grids around body boundaries. The present scheme is used to simulate steady flow around a semicircular cylinder mounted on the bottom of flow domain and calculated results are validated by results of a body fitted grid method. Finally, present method is applied to a complex flow around multi body and the usefulness is checked by investigating calculated results.

  • The purpose of this study is to make an ideal dummy for adult Maltese with proper investigation of its character and direct measurement of dog body-shape. The results of the study are as follows; First, there were 6 factors to affect the characteristics of Maltese body in the analysis, which are size of body, leg shape, chest shape, leg thickness, body length, length between fore-legs. In the cluster analysis with the 6 factors there were two types of Maltese body. Type 1 has body characteristics with large body, thick leg, and small distance between front legs. Type 2 has average size of all factors including body size, leg thickness, and length between fore-legs. Second, type 2 was selected as a representative one to make a dummy reflected body shape of characteristics because it took 67.71% from entire considered factors and has average value in the measured size. The first dummy pattern was planned by copying the surface area of the representative body shape with the method of surgical tape. A dummy of single body with trunk and legs was made using 30's cotton cloth, polyester inside batting, compressed form PVC and metallic wire on the joint of trunk and legs to support dummy shape. The second pattern was made by correcting size difference of the pattern and adding the pattern of neck covering plate, metal magnetic button was inserted on the center of joint area of trunk and legs to make detachable legs for easy slip on and off the pet's wear.

  • The purpose of this study was to classify the lower body of the lost women and to investigate the three-dimensional characteristics of each lower body somatotype of them. The subject were ninety seven women whose. age were twenties and whose height and bust girth were in the range of mean$\pm1\delta$ of typical body size of twenties' Korean women. The forty one variables of their lower body were measured by Martin's Anthropometric Instrument. And they were analyzed for mean, standard deviations factor analysis, and cluster analysis. In the second phase of analysis, the three participants were re-selected in each type were measured by Sliding Guage and analyzed their lower body somatotype. The results were as follows; The components of lower body of 20s' women were extracted with 7 factors through factor analysis and orthogonal rotation by the method of Varimax. The rate of the cumulative contribution was 84.1% the first factor was the thickness of lower body, the second factor was the vertical size of lower body the third factor was the front shape of hip, the forth factor was the vertical size of hip, the fifth factor was the shape of abdomen, the six factor was the flat-ratio of waist and the seventh factor was flat-ratio of hip. The somatotype of 20's women's lower body can be classified into 3 types. Type 1 is the standard somatotype of 20's women's lower body and the 34.0% of the participants in the study was categorized into type 1. Type 2 is a short and corpulency type with protruded abdomen and hip and the 29.9% of the participants in the study was categorized into type 2. And the type 3 is a tall and thin type with plat abdomen and hip and the 37.1% of the participants was categorized into type 3.
