The purpose of this study was to investigate the wearing condition according to different basic slacks'patterns and to provide fundamental data on structuring slacks' pattern using the multi-dimensional measuring method. 3 different kinds of basic slacks' patterns (A, B, C) were used and cross-sectional measurements of 6 parts were analysed. The results were as follows; 1) It revealed that the girth of waist, hip and thigh effected the degree of ease amounts. 2) Moira pattern shape fully supported that the considerable body parts affected the change of ease amounts. 3) Basic pattern A was usually expected to be suitable for standard-sized or unmarried women who had not experienced body-type change. 4) Basic pattern B and C were suitable for large-sized or married women whose body·type had changed. Therefore the crotch length and depth, gredient of center back line has to be set up accurately.

Permanent magnets of Nd-Fe-B group have kept a key post in the permanent magnet market and used in various parts. Tube Process is a process to produce permanent magnets using a deformable tube for denslfication of powder magnets. Advantage claimed for this process is that it can accomplish both densification and anisotropication in one step forming. In this paper. the simulation has been carried out for a full Tube Process in a closed Qe considering the compressibility of material, arbitrary curved shape and deformable body contact between Nd-Fe-B powder magnet and copper tube. The results show that the analysis of Tube Process is applicable with great help in the stage of preform design.

This paper describes with the stator analysis and design of a ring type ultrasonic motor. The design for piezoelectric ceramic and elastic body of stator were calculated by using the finite element method (FEM) that consider the resonance frequency, vibration mode and coupling efficiency. Namely, such results were acquired the calculation result of the piezoelectric ceramic thickness 0.5[mm], elastic body thickness 2.0[mm], resonance frequency 51.8[kHz], vibration mode 7 order and coupling efficient 12.5[%], the outer and inner diameter of vibrator 50[mm], 38[m]. On the basis of such result, the ring type ultrasonic motor was manufactured. Also for driving characteristics of ring type ultrasonic motor, 2-phase inverter was constructed. Then the propriety of this paper was established from comparision of the simulation and an experiment results of the ring type ultrasonic motor.

The impulsive spin-up flow in a shallow rectangular container is analyzed numerically by quasi 3-D unsteady laminar flow. In the non-inertia coordinates, the flow is generated by the virtual forces as Coriolis force, etc.. After the boundary layers grow up near sidewalls, primary vortexes separate from the sidewalls. As the Reynolds number increases, the subsidiary vortexes take place in the boundary layer. The rigid body rotation is started from the inner region and propagated to the outer region, finally all the fluid reaches the rigid body rotation. According to the Reynolds number and the aspect ratio, the development of vortex pattern is symmetric or asymmetric.

Investigated In this paper is the shock reflection from a blunt body, In particular, a circular cylinder of 20 mm diameter, for the weak shock impinging in the range 1<$M_s$ <2. Pressure and shock speed are measured for various shock strengths. Double-pulse holographic interferograms are taken to study the unsteady flow field at $M_s=1.34$. These experimental results are, in overall, well compared with the unstructured adaptive finite volume computation of the Euler equations performed in this study. Correlation of incident and reflected shocks and shock-shock locus obtained by experiment, computation, and theory are presented in parallel.

In this paper, a numerical procedure for the calculation of the incompressible Navier-Stokes equations in a generalized nonorthogonal body fitted coordinate system is proposed and is validated through three test problems. Present numerical procedure derives the pressure equation by using the pressure substitution method on the regular grid system, and discretized momentum equations are based on the covariant velocity components. Cavity flow, backward facing step flow, and two dimensional channel flow with a sinusoidal wavy wall are chosen as three test problems. Numerical solutions obtained by present procedure shows a good agreement with previous numerical and/or experimental results. Convergence rate is also satisfactory.

The body fat weight changes were 26.92 2.04kg to 20.74 1.98kg for A group, and 27.86 3.37kg to 24.58 3.02kg for B group. The body weight chages were 72.36 3.18kg to 64.54 2.55kg for A group, and 72.48 3.14kg to 67.74 3.11kg for B group. The muscle rate changes were 43.86 1.63kg to 43.10 1.76kg for A group, and 42.72 1.22kg to 41.60 1.86kg for B group. Overall, A group was superior to B group. 13. After being treated for obesity, 13 patients used exercise treatment (65%), 5 continued to receive obesity treatment (25%), and 2 used diet (10%). Based on these results, we could conclude that the importande of setting a criterion of obesity and weight control have changed according to changes in social and cultural values, and that treatment of obesity through Oriental medicine and research should keep up with changes in esthetic and psychological values.

The differences between floating and grounded body effects in polycrystalline silicon thin-film transistors (polysilicon TFTs) are investigated by making a body contact. The floating body effects such as kink effect, subthreshold slope change, and body current characteristics are explained and modeled by impact ionization, which causes source body turn on, and activates the parasitic bipolar junction transistors (BJTs). These effects become crucial for channel lengths of 4㎛ or shorter. Our data show that making a body contact reduces kink effects significantly and identifies impact ionization mechanism in polysilicon TFTs.

This experimental study was designed to investigate the inhibitory effects of hot water extract of Yukeuigambi-tang (YEGT) on high-fat diet-induced obesity and hyperlipidemia in C57BL/6 mice. Animals were divided into normal, control, YEGT(sample A 3.8 g/kg, and sample B 7.6 g/kg) treated group. Obesity with hyperlipidemia was induced by high fat diet treatment for 6 weeks. YEGT was given to the animals by oral gavage. The effect of YEGT on the body weight change, total cholesterol, HDL-cholesterol, LDL-cholesterol, triglyceride, and leptin levels in serum were evaluated. In respect to the body weight change, sample B significantly reduced body weight compared with control group in the 6th weeks. In the total cholesterol, triglyceride, and leptin level, sample B significantly reduced all of them compared with control group; sample A significantly reduced triglyceride and leptin levels compared with control group. The above results suggest that YEGT is effective to prevention and treatment of obesity and hyperlipidemia.

These experiments were carried out to develop new techniques for In Vitro separatin of X-and Y-bearing spermatozoa. The bull semen was applied to the various Gel-Columns filled with swellen Sephadex G-50 Fine and then elutriated wtih Locke solution (elutriation rate; 1ml/3-4min., 1ml/1-2min.). Elutriated solution was fractionated into 1ml by automatic Fraction Collector and spermatozoa included in each fraction were subjected to the estimation of viability and recovery rate, and to B-body test. The results obtained in these experiments were summarized as follows: 1. When the column size and the elutriation rate were adjusted to 15$\times$1.6cm and 1ml/3-4min., respectively, the highest sperm concentration was obtained from the 8th to the 12th fraction. 2. As a trend, the viability of spermatozoa was improved by chromatography, and the degree of improvement ranged 5 to 10 percentage. 3. The average recovery rate of spermatozoa applied to column was 73.2 percentage and ranged 52.6 to 81.3 percentage. 4. The lowest rate of B-body bearing spermatozoa following chromatography was obtained when the column size and the elutriation rate were adjusted to 15$\times$0.8cm and 1ml/1-2min., respectively.
