The aim of the present experiments was to investigate the effect of Palmijihwangtang water extracts on the plasma renin activity and plasma levels of atrial natriuretic peptide and aldosterone in rats. The results of this study were as follows 1. Plasma renin activity was not different after the administration of Palmijihwangtang water extracts 2. Plasma levels of aldosterone decreased significantly after the administration of Palmijihwangtang water extract 3.0 ml/kg. 3. Plasma levels of atrial natriuretic peptide (ANP) decreased significantly after the administration of Palmijihwangtang water extracts.

The purpose of this study is to ensure natural restoration of gingiva's form by making effective use of materials in a bid to improve the technique of festooning for denture base. 1. The improved technique is expected to prevent the degradation and deformation of cavity structure and restore it. 2. The improved technique is expected to prevent the change of facial appearance from esthetic viewpoint and restore it. 3. The improved technique is expected to impress again the deformed part on wax denture for additional festooning.

The performance of insulate materials gets worse with stress time in power system and because this causes lowering of function and accidents in equipment, development and performance improvement of excellent insulate materials are needed to make stable system. In this paper, to study the influence of degradation in XLPE, inner semiconducting layer and outer semiconducting layer, we studied dielectric characteristics at temperature $25{\sim}100[^{\circ}C]$ and frequency $20{\sim}1[MHz]$ and volume resistivity at temperature $25{\sim}100^{\circ}C$, voltage.

Bioassay-directed chromatographic fractionation of a methylene chloride extract of Ailanthus altisshima indicated the presence of 20(S). 24(R), epoxy-25-hydroxydammarane-3-one(compound 1. ocotillone). which was isolated from this plant for the first time. Antimicrobial activity of compound 1 was measured by its degree of growth inhibition against bacterial and fungal cells and by a hemolytic assay with human erythrocytes, respectively. (omitted)

Purpose : The purpose of this research was to determine the effects of Proprioceptive Neuromuscular Facilitation(PNF) and Functional Electrical Stimulation(FES) of combined on gait ability in hemiplegic gait. Methods : The subjects of this study were 13 hemiplegic patients. Each subjects was taken PNF pattern and FES of combined with 5 times per week for 4weeks. Pre- and Post-intervention change in gait ability were measured using an Timed up and Go test, stride length of the affected side, step length of the affected side. The data were analyzed using the paired t-test. Results : The results of this study were showed significantly improvement in TUG, stride length of the affected side, step length of the affected side after intervention. Conclusion : These results suggest that the Proprioceptive Neuromuscular Facilitation(PNF) and Functional Electrical Stimulation(FES) of combined exercise is an effective way of improving gait ability for hemiplegic patients.

The application of BZO (Boron-doped Zinc Oxide) films use as the TCO(Transparent Conductive Oxide) material for display and solar cell industries, where the conductivity of the BZO films plays a critical role for improvement of cell performance. Thin BZO films are deposited on glass substrates by using RF sputter system. Then charging flow rates of O2 gas from zero to 10 sccm, thereby controlling the impurity concentration of BZO. BZO deposited on soda lime glass and RF power was 300 W, frequency was 13.56 MHz, and working pressure was $5.0{\times}10-6$ Torr. The Substrate and glass between distance 200 mm. We measured resistivity, conductivity, mobility by hall measurement system. Optical properties measured by photo voltaic device analysis system. We measured surface build according to oxygen flow rate from XPS (X-ray Photoelectron Spectroscopy) system. The profile of the energy distribution of the electrons emitted from BZO films by the Auger neutralization is measured and rescaled so that Auger self-convolution arises, revealing the detail structure of the valence band. It may be observed coefficient ${\gamma}$ of the secondary electron emission from BZO by using ${\gamma}$-FIB (Gamma-Focused Ion Beam) system. We observed the change in electrical conductivity by correlation of the valence band structure. Therefore one of the key issues in BZO films may be the valence band that detail structure dominates performance of solar cell devices. Demonstrating the secondary electron emission by the Auger neutralization of ions is useful for the determination of the characteristics of BZO films for solar cell and display developments.
