Objective : The purpose of this study is to extend indications of Four-Constitution Medicinal formulas by comparing with formulas on Dongeuibogam(東醫寶鑑), focusing on their composition. Method : 1. We analyzed the composition of Sanghan formulas(傷寒方) and non-classical formulas(後世方) which are mentioned on Donguisusebowon(東醫壽世保元), focusing on their composition. 2. We analyzed the composition of formulas on Dongeuibogam(東醫寶鑑) comparing with Bojungyikgi-tang for So-Eum type. Result & Conclusion: 1. Je-Ma Lee didn't say the Sanghan formulas(傷寒方) and non-classical formulas(後世方) with criterion of composition on his book. 2. We finally selected one formulas(Insamhwanggi-tang) and its effect as similar formulas with Bojungyikgi-tang for So-Eum type.

Objectives : The object of this study was to observe the pharmacological effects of Yookmijihwang-tang-gamibang (Liuweidihuang-tang-jiaweifang, YGB) consisted of 17 types of herbs has been traditionally used in Korean medicine for treating various disorders in clinics, aqueous extracts on the genetically obese and type II diabetic C57BL/6JHam-ob/ob(ob/ob) mice. Methods :Three different dosages of YGB were orally administered, once a day for 28 days to ob/ob mice with ob/ob control and C57BL/6JJms normoglycemic intact mice. Four weeks after treatments of YGB: the changes on the body weight, food consumption, blood glucose levels, leptin and adiponectin contents were observed for monitoring the antiobese and antidiabetic effects of YGB. The effects were compared to those of CLA(conjugated linoleic acid) which improve type II diabetes and inhibit related obesity. Results : After end of 28 days of continuous treatments, ob/ob control showed increases of adipocyte hypertrophy, vasodilated atrophic glomerulus which were detected with marked hyperplasia of pancreatic islets, insulin and glucagon producing cells. These obese and related type II diabetes induced in ob/ob mice were markedly and significantly inhibited by 28 days of continuous treatment of three dosages of YGB. The YGB 50mg/kg showed similar favorable effects on the diabetes and related diabetic complications as compared with CLA 750mg/kg in ob/ob mice of the present study. Conclusions : The results obtained in this study suggest that over 25mg/kg of YGB extracts favorably retarded the obese and type II diabetes in genetically obese and type II diabetic ob/ob mice.

This study sought to understand the mechanical behavior according to the shape of the connecting part of the hybrid beam. This part is composed of central steel. with the end reinforced by concrete in the experiment of cyclic loading. The experimental result was compared and verified with the ultimate strength formula. Likewise, the composite effect and the effectiveness of seismic capacity and stress transmission were examined. The types of each setup were as follows: main bars by welding type, reinforcing by end-plate type, reinforcing by shear connector type, and shear connector type. Results showed that the reinforcing by end-plate type and the shear connector type had excellent strength and seismic capacity as well as better stress transmission. This was due to the unity between reinforced concrete and the steel's connecting part. However, the experimental result was somehow different from the previously established ultimate strength formula. Thus, a definite ultimate strength formula is required.

Objective : The present study was designed to investigate whether the water extract of the root of Scutellaria baicalensis could regulate lipopolysaccharide (LPS)-induced type 1 interferon. Methods : To evaluate of type 1 interferon inhibitory effect of the root of Scutellaria baicalensis, we examined type 1 interferon in LPS-stimulated RAW264.7 cells. Furthermore, Interleukin (IL)-10 and interferon regulatory factor (IRF) - 1, 7 expression level were examined to study the inhibition mechanisms. Results 1. Extract from the root of Scutellaria baicalensis didn't have any cytotoxity itelf. 2. Extract from the root of Scutellaria baicalensis inhibited interferon-a,b in dose dependant- and type 1 interferon production in time dependant manner. 3. Extract from the root of Scutellaria baicalensis reduced IL-10 and IRF-1, 7 production in LPS-stimulated RAW 264.7 cells. Conclusion : The extract from the root of Scutellaria baicalensis down-regulated LPS-induced type 1 interferon through suppression of IL-10 and IRF-1, 7 expression. This results suggested that the extract from the root of Scutellaria baicalensis may be a beneficial drug against inflammatory diseases.

The leakage and rotordynamic coefficients of see-through type gas labyrinth seals are determined using a two-control-volume-model analysis with Moody's wall-friction-factor formula which is defined with a large range of Reynolds number and relative roughness. Jet flow theory are used for the calculation of the recirculation velocity in the cavity. For the reaction force from the labyrinth seal, linearized zeroth-order and the first-order perturbation equations are developed for small motion about a centered position. The leakage and rotordynamic coefficient results of the present analysis are compared with Scharrer's theoretical analysis using Blasius' wall-friction-factor formula and Pelletti's experimental results. The comparison shows that the present analysis using Moody's wall-friction-factor formula and Scharrer's theoretical analysis using Blasius' wall-friction-factor formula give the same results for a smooth seal surface and the range of Reynolds number less than $10^5$.

This paper presents linear algebraic equations in the form of recursive formula to compute elastokinematic characteristics of a suspension system. Conventional methods of elastokinematic analysis are based on nonlinear kinematic constrant equations and force equilibrium equations for constrained mechanical systems, which require complicated and time-consuming implicit computing methods to obtain the solution. The proposed linearized elastokinematic equations in the form of recursive formula are derived based on the assumption that the displacements of elastokinematic behavior of a constrained mechanical system under external forces are very small. The equations can be easily computerized in codes, and have the advantage of sharing the input data of existing general multi body dynamic analysis codes. The equations can be applied to any form of suspension once the type of kinematic joints and elastic components are identified. The validity of the method has been proved through the comparison of the results from established elastokinematic analysis software. Error estimation and analysis due to piecewise linear assumption are also discussed.

In this paper, we derive a change of scale formula for conditional Wiener integrals, as integral transforms, of possibly unbounded functions over Wiener paths in abstract Wiener space. In fact, we derive the change of scale formula for the product of the functions in a Banach algebra which is equivalent to both the Fresnel class and the space of measures of bounded variation over a real separable Hilbert space, and the $L_p-type$cylinder functions over Wiener paths in abstract Wiener space. As an application of the result, we obtain a change of scale formula for the conditional analytic Fourier-Feynman transform of the product of the functions.

One of the critical issues associated with the 40mm long hollow cylinder's development and maintenance is the prediction of cylinder erosion. The actual firing test is the most accurate method to measure the cylinder erosion rate. But it costs a great deal and requires a long measurement time. Hence many empirical methods have been proposed to predict the erosion rate and life span of long hollow cylinders. An EFC formula is calculated. An approximate erosion formula for the ammunition type A is derived to interpolate 16 observation values up to 4,000 rounds. A new erosion equation and muzzle velocity formula are also suggested. Several numerical results are presented.
