Objective : The purpose of this study was to investigate the significance of the Oriental medical treatment using He-Ne laser with low energy intravascular Laser Irradiation of Blood(ILIB) through the superficial venules. Methods : The investigation of details connected with the superficial venules in the literature is performed. The investigation of details connected with the pricking blood techniques through the superficial venules in the literature is performed. The classification of the pricking blood techniques through the superficial venules by the blood-letting puncture methods in the literature is performed. The arrangement of domestic clinical treatises on the effectiveness of medical treatment using He-Ne laser with low energy ILIB through the superficial venules is performed. The consideration on the methodology for the improvement of the clinical effectiveness of He-Ne laser with low energy ILIB through superficial venules is performed. Results and Conclusions : The superficial venules are small arteries, veins and capillaries in the superficial region of the human body. In the pricking blood techniques, there are the blood-letting puncture using the implement of acupuncture to the Jing points, Extra points and superficial blood vessels and the acupuncture using the Hirudo. The methods of the blood-letting puncture are classified into the venous blood-letting puncture, the pricking , the picking out white fiber-like substances from the subcutaneous tissue, the cluster needling, the scattered needling, the blood-letting puncture of the tready collateral branch of the large channel and the blood-letting puncture of skin. The He-Ne laser with low energy ILIB through the superficial venules belongs to the Oriental medical treatment as the method of the blood-letting puncture in the vein of cubital fossa. The He-Ne laser with low energy ILIB has an effect on hyperfibrinogenemia, hyperlipidemia, speech and motor dysfunction in the case of cerebral infarction, headache, dizziness, pain and numbness. It is considered that fundamental research on the biological change of the human body, the experimental animal and the unicellular animal, and research on the effectiveness and the safety, and the development of He-Ne laser with low energy ILIB of an effective wavelength range are necessary.

There is a close relation between the heat generation in the fuel cell stack and the fuel cell performance. In PEM fuel Gell vehicles, the stack coolant temperature is about 65?C, which is far lower than that for general automobile engine. Therefore, it is hard to release heat generated in the stack by using a radiator of limited size because of the reduced temperature difference between the coolant and the ambient air. In this study, indirect stack cooling system using CO₂ heat pump was designed and its stack cooling performance in releasing heat to the ambient was investigated. This work focuses on a series of processes that grasp the relation among the fuel cell power, the radiator capacity and the stack temperature. The purpose of this work is to find out a way to properly release sufficient amount of heat through the finite sized radiator, so that the stack power general ion can not be deteriorated due to the stack temperature increase. The optimization between the compressor power consumption and the fuel cel1 output power can be carried out to maximize the performance of fuel cell system.
V<sub>2</sub>O<sub>5</sub>/TiO<sub>2</sub> 촉매의 활성금속 함량이 촉매 활성에 미치는 영향

In this study, the activity test and characterization were performed to evaluate the hydrogen sulfide removal characteristics using a V/TiO<sub>2</sub> catalyst at room temperature. The optimal vanadium loading was 10 wt%, and the durability was greater than 60 minutes at 60~80% relative humidity. The Brunauer-Emmett-Teller (BET) surface area and raman spectroscopy results confirmed that the structure of the vanadium site exposed to the surface was a dominant factor in catalyst activity. From Scanning Electron Microscope (SEM), Energy Dispersive Spectroscopy (EDS) and X-ray crystallography (XRD) analyses, it was found that sulfur can be accumulated on the catalyst surface, which results in a decrease in durability under catalytic activity tests. Therefore, it is judged that a combined process of catalytic oxidation and regeneration is needed.
