This study has analyzed the engineering characteristics of resource-cycling mortar according to the variation of fine aggregate type using illite with high development potentials by setting the goal as developing eco-friendly construction materials. As a result, while flow has increased if recycled fine aggregate and waste refractory are used separately or mixing them adequately in case of flow and compressive strength, the flow had somewhat declined followed by illite replacement. However, the possibility of such usage is determined to be adequate if used by mixing illite, recycled fine aggregate and waste refractory properly due to the dry shrinkage effect.

This is a literature Study on ophthalmologic disease remedies of the four famous physicians in Jin Yuan period. The results were as follows: 1. Yu Wan So regarded the cause of ophthalmologic disease as the wind and heat(風熱), the blood deficiency(血少), or the deficiency of vital function and essence ,of the kidney(腎氣虛). For each treatment he used the method to remove wind and heat(除風散熱), the tranquillizing and tonifying method to nourish the heart and to relieve mental strain due to dificiency of vital essence(養血安神). the method to nourish Yin in the kidney(補腎水). The important nature of the these medicines is bitter and cold. 2. Jang Jong Jeung regarded the cause of ophthalmologic disease as the blood excess(血太過). or the blood deficiency(血不及). or the fire and heat(火熱). For each treatment he used the method to extract blood(出血療法). the method to nourish the liver and the kidney(補肝腎療法). or the method of vomiting and diarrhea(吐不法). The medicines are usuallly classified into external treatment medicines(外用藥). medicines to disintegrate mass(破積聚藥). purgating medicines(攻下藥). 3. Lee Dong Won regarded the cause of ophthalmologic disease as the spleen and the stomach weakness(脾胃虛弱), excessive fire in the heart(心火太盛). For each treatment he used the method to tranquillize the spleen and the stomach (調理脾胃). the tranquillizing and tonifying method to nourish the heart and to relieve mental strain due to deficiency of vital essence(養血安神). 4. Ju Dan Gye regarded the cause of ophthalmologic disease as the wind and heat(風熱). the blood deficiency(血少). the mental exhaustion(神勞). the kidney weakness(腎弱). For each treatment he used the method to remove wind and heat(除風散熱), the method to nourish blood and yin water(養血補水), the method to relieve mental strain and to remove spiritual heat(安腎瀉神火). the method to nourish yin water(養陰水). These drugs are usually classified into the medicines to remove endogenous heat(淸熱藥). the medicines to nourish yin(補陰藥).

Lee Jema said in his book, Dongui Susebowon, that the prescriptions for Soum constitutional type were already developed by doctors during the Song Jin Yuan China around 10th-13th century. Those prescriptions were common techniques that were used throughout the East Asian region. Among them, Lee Jema specially selected some candidate formulas and modified them according to his constitutional theory. This study investigated how similar his modified prescriptions to original formulas through database[ancient formula database] analysis. 24 out of 24 Soum prescriptions selected meaningful ingredient herbs from the original formula. A 50% or higher concordance rate compared to the original formulas. There are only 9 treatment prescriptions that cannot be checked in the ancient formula database. A future task will be to reveal the practical meanings of the ingredients Lee Jema adjusted for the Soum constitutional type patients.

Objectives: Uwhangchungsim-won(UC) has been used in the treatment of a wide variety of conditions including stroke, hypertension, arterosclerosis, autonomic imbalance, and mental instability, in Korean traditional hospitals. The aim of this study was to evaluate the effect of DC on cerebral hemodynamics and to determine the appropriate dosage. Methods: We studied changes in hyperventilation-induced cerebrovascular reactivity and mean blood flow velocity of the middle cerebral arteries(MCAs) were studied by means of transcranial Doppler ultrasound. Changes in mean blood pressure, pulse rate and expiratory CO2(PECO2) were observed using Cardiocap TM/5. Six healthy young volunteers who were administrated with full doses of DC for group A, and half doses for group B. Six other healthy subjects comprised the control group. The evaluation was performed during basal condition, and repeated at 20, 40, 60, 120, and 180 minutes after administration. Results: Increases of cerebrovascular reactivity and mean blood flow velocity in the middle cerebral artery in group A were significantly different compared with group B and the control group (p<0.1). Mean blood pressure, pulse rate and expiratory CO2 did not change during the observation and were not different among these three groups. We observed that in cerebrovascular reactivity induced hyperventilation, group A was most effective at 40 minutes after administration, and its effectiveness lasted for 120 minutes. Conclusions: This study provides evidence for UC, in full doses, as an agent for dilation of the cerebral arteriols to increase hyperventilation-induced cerebrovascular reactivity as a consequence of faster recovery of blood flow velocity.

In this research the processing method of Desulfurized Plaster is changed to cyclotomy, 0.3mm sieve analysis and 500℃ heat exposure, and by changing the mix rate of the binding agent to 0~20%, it was applied to mortar that used cyclic aggregate and blast furnace slag for testing. The test results showed that the flow decreased in the order of cyclotomy, high heat exposure, and sieve analysis according to the mix rate of FGD, and while the air volume decreased for cyclotomy, it was shown to have almost no effect on sieve analysis and high heat exposure. The setting time accelerated as the mixing rate of FGD increased, and the compression strength increased as the mixing rate of FGD increased and especially showed a high trend with cyclotomy and sieve analysis.

Objectives : We investigated the effects of fermented soybean(FSOB) on body weight and examined whether hepatic lipid accumulation are inhibited by it in high fat diet-fed obese male mice. Methods : 8 weeks old, high fat diet-fed obese male mice were divided into 5 groups: C57BL/6N normal, control, FSOB(1), (2) and (3). After mice were treated with FSOB for 9 weeks, we measured body weight gain, food intake, feeding efficiency ratio, fat weight, plasma leptin and lipid levels. We also did histological analysis for liver and fat on the mice. Results : 1. Compared with controls, FSOB-treated mice had lower body weight gain and adipose tissue weight, the magnitudes of which were prominent in FSOB(3) and FSOB(1). 2. Compared with controls, FSOB-treated mice had lower feeding efficiency ratio and blood plasma leptin levels, the magnitude of which was prominent in FSOB(3). 3. Compared with controls, FSOB-treated mice had lower blood plasma total cholesterol and LDL-cholesterol levels. 4. Blood plasma AST and ALT concentrations were not changed by FSOB, indicating FSOB do not show any toxic effects. 5. Consistent with their effects on body weight gain, the size of adipocytes were significantly decreased by FSOB, whereas the adipocyte number per unit area was significantly increased, suggesting that FSOB decreased the number of large adipocytes. Hepatic lipid accumulation was decreased by FSOB. Conclusions : These results demonstrate that FSOB effectively reduces body weight gain, feeding efficiency ratio, blood plasma leptin level and improves hepatic lipid accumulation.

The electromagnetic parameters of a permanent magnet synchronous motor (PMSM) such as the open load permanent magnet flux, d axis reactance $X_d$, and q axis reactance $X_q$, are most essential to the performance analysis and optimization design of the motor. Based on the numerical analysis of the 3D electromagnetic field, the three electromagnetic parameters of permanent magnet synchronous motors with U form interior rotor structures are calculated by FEA. The rules of the leakage coefficient and reactance parameters changing with the air gap length, permanent magnet magnetism length, and isolation magnetic bridge dimensions in the rotor are given. The calculated values agree well with the measured values. The FEA results are integrated with the self compiled electromagnetic design program to optimize the prototype motor. The tested performances of the prototype motor prove that the method is suitable for the optimization of motor structure.
