In order to reduce systemic side effects following administration, flurbiprofen was formulated as O/W microemulsion consisting of the surfactant, oil phase and aqueous phase. Particle size distribution, apparent viscosity, solubility and skin permeation of flurbiprofen in various vehicles and microemulsion were evaluated. The domain of O/W microemulsion's phase diagram had difference between oil types and the area of O/W microemulsion was wide distributed by adding to PG and cosurfactant than that of water alone. As increasing 10, 15 and 20% of Brij 97 content and 1, 2.5, 5% of oil content, the solubility of flurbiprofen in O/W microemulsions and various vehicles was 400~1,000 and 10~500 times higher than that of control. Also apparent viscosity of soybean oil microemulsions was higher than that of IPM microemulsions and that of vehicle were increased as increasing vehicle content. Since skin permeation of flurbprofen decreased as increasing viscosity, in each vehicle, it was not affected 2% β-CD and decreased as increasing PG content and to 2, 5 and 10% of HP-β-CD. In O/W microemulsion, 5% soybean oil, 20% Brij 97 and 75% water(A-1) with high viscosity showed low skin penetration.

The control subjects donated their blood at pre and post(after six month). The collected blood were analyzed for the triglyceride, cholesterol, High density lipopro -tein cholesterol and HDL-C/TC ratio. The result through the statistical analysis of this data were summarized as follows The pre-levels of triglyceride and total cholesterol in Athlete group, especially Bgroup were lower than those in Non-athlete group(p<.01). level and HDL C/TC ratio were highest in B group among three group(p<.05). HDL-C level and HDL-C/TC ratio in both athlete group, especially A group were significantly decreased after three and six month(p<.01) while in control group all item were not changed. The result indicated that Triglyceride cholesterol in pre-adolescent girl can be significantly changed by three month training and the change of need more long term training.

韓國에서의 高等失業問題 硏究를 위한 豫備的 接近

This paper addresses a new approach to the study of educated unemployment problem. After reviewing the extant literature on this subject area, it provides a distinction for the related concepts and further suggests that there should be five different aspects of this educated unemployment phenomenon. The author maintains that the conventional explanations begin by assuming a natural balance of power distribution and end up examining a market structure as given. Within this narrow scheme, it is no wonder to regard any failure to get employment opportunites from the labor market as an individual problem. The author also states that radical perspectives in general have a tendency to over-react to conservative standpoints. In going too far in the opposite direction, the former have substituted impersonal non-market forces, such as capitalism or world-system, for the latter's impersonal market forces. Finally, he argues that a balanced version should include serious attention to the ways in which the domestic political-economic powers have responded to changes in the international division of labor. The role of the state within a develop-ing country, in general, and its specific policies in the vortex of class conflicts, in particular, should be examined by a historical-structural analysis, as for fruitful research in the future.

AC powder electroluminescence(EL) device consists of seven layers : PET substrate, transparent electrode, phosphor layer, dielectric layer, two layer metal electrodes and protective layer. Etch layer needs to control to improve electrical and optical properties. Both phosphor and dielectric layer among them is more important to increase its properties. For long-time reliability, proper choices of passivation and sealing material are essential. In this paper, influence of phosphor and dielectric layer thickness on EL performance is studied. Type of cellulos is selected as a sealing material to avoid moisture. To add two type of plasticizer to resin improves flexibility and passivation of EL devices. Through this experiments, technologies of fabrication low-cost thick film EL device can be established.

Liquid wastes containing uranium ions in high concentration of chemical salts havebeen treated by electrosorption on a activated carbon fibers(ACFs) electrode. Effectiveuranium (VI) removal is accomplished when the potential is -0.5V(vs. Ag/AgCl) ormore negative. For a feed concentration of 100mg/1, the concentration of U(VI) in thecell effluent is reduced to less than 1mg/1, and electrosorption capacity over 500mg/uranium/gACF is reached. The adsorbed uranium can be desorbed up to 99%for 20h by passing a 1.9N NaCl solution at pH 3 through the cell and applying a potential of +1.2V. The amount of desorbed uranium increased as the solution pHwas lowered and the applied potential increased.

The purpose of this study is to measure the changes of regional cerebral blood flow (rCBF) and blood pressure (BP) of Cortex Acanthopanacis in rats, and to determine the effect of Cortex Acanthopanacis on phenylephrine (PE) induced contraction of isolated rat thoracic aorts. The measurement was continually monitored by laser-doppler flowmeter (Transonic Instrument, USA) and pressure transducer (Grass, USA) in anesthetized adult Sprague-Dawley rats through the data acquisition system composed of MacLab and Macintosh computer. Contractile force was measured with force displacement transducer under 1.5 g loading tension. The result of this experiment was as following; 1. Cortex Acanthopanacis did not effect the changes of rCBF and blood pressure significantly. 2. Contractions evoked by phenylephrine were decreased significantly by Cortex Acanthopanacis 3. L-NNA, ODQ, atropine and indomethacin significantly altered the relaxation of Cortex Acanthopanacis. 4. Propranolol did not change the relaxation of Cortex Acanthopanacis. These results indicate that Cortex Acanthopanacis did not change the rCBF and BP, but Cortex Acanthopanacis can relax PE induced contraction of isolated rat thoracic aorta and that this increasing contraction related to endothelium and various mechanism.

This paper proposes a single-stage high frequency resonant AC-DC converter using zero voltage switching with high input power factor. The proposed high frequency resonant converter ingegrates a half bridge boost rectifier as power factor corrector(PFC) and half resonant converter into a single stage. The input stage of the half bridge boost converter is working in discontinuous conduction mode(DCM) with constant duty cycle and variable switching frequency. Therefore, high power factor is achieved naturally. The results of simulation using the Pspice have demonstrated the feasibility of the proposed AC-DC converter. The proposed converter will be able to be practically used as power supply.
