Yeon Ju Hwan (蓮珠丸) is a Chinese patent medicine which has been used for improvement of blood circulation and thrombolysis in Korea. It consists of 28 kinds of powdered crude drugs. For the identification of individual ingredients in such powdery mixtures, microscopic method may advantageously be used, as it requires only small amount of specimens. And also it is considered a technique of choice since it takes only minimum time and requires a simple process. In this paper, the effectiveness of this method is exemplified by the identification of the ingredients in Yeon Ju Hwan, which contains 28 powdered crude drug ingredients.

A syudy on hospital architecture was as a circulation effective work as most amount and function at the view of nurse, staff until now. The architect do not have a data about planning patient-centered hospital, do not reflect a demand of patient at the planning step. This study arrange what is concept of patient-centered, recently concept of patient-centered hospital is importantly raised, at centering around a ward that a life of patient is the most influenced. This study make clear character of patient-centered hospital at home, the problem and demand of patient through the P.O.E.

Rubber compounds have high viscoelastic property. One of the viscoelastic behaviors during profile extrusion is the swelling of extrudate. In this study, die swells of rubber compounds at the capillary die have been investigated through experiment and computer simulation. Experiments and simulations have been performed using fluidity tester and commercial CFD code, Polyflow respectively. Die swells of rubber compounds in a capillary die were predicted using non-linear differential viscoelastic model, Phan-Thien-Tanner(PTT) model for various relaxation times and relaxation modes. The results of simulation were compared with the experiments. Pressure and velocity distribution, and circulation flows at the comer of capillary die have been investigated through computer simulation. It is concluded that the PTT model successfully represented the amount of the die swell of rubber compounds for various relaxation times at different modes.

This research aims to develop parts for advanced fuel/oil filtering re-circulation applicable to this kind of regulation proof engines. These parts can playa role of converting traditional air emission type crankcase into recovery type crankcase so that the engine can deal with environmental regulations, which do not allow minimal amount of toxic gas discharge. For the experiment, test method and specially made testing equipment are prepared. The results showed that oil separation efficiency of the cone type CCV(Crank Case Ventilation) system was higher than one of cylinder type both in bench test and in engine.

The purpose of this study is to examine the energy consumption, carbon dioxide emission & energy cost of district heating using sewage source. The annual TOE of heat pump using sewage source save 37.1 percent than city gas boiler. And annual carbon dioxide emission of heat pump cut down 41.3 percent than city gas boiler. If it charges the rate schedule for district heating to apartment resident, collected amount are 3,127,170 thousand won. As energy cost of heat pump & circulation pump are 1,378,072 thousand won. the profits are 1,749,098 thousand won. As payback period is 8.97years, applicability is low level. However, it has advantages in energy consumption, carbon dioxide emission & energy cost. Therefore, it needs to proceed through government assistance.

Thin. Boron-doped conducting diamond films are expected to be excellent electrodes for industrial electrolysis. Boron-doped conducting diamond films were used as anode for generating ozone gas by electrolysis of acidic solution. In this work, we have studied ozone generating system using Boron-doped Diamond electrode. Electrochemical cell and ozone generating system were designed for decreasing the temperature of the system. which was elevated during the reaction. by circulation of electrolyte in the system. In order to determine the ozone generation properties of diamond electrode. experimental conditions, electrolyte concentration, temperature, flow rate and reaction time were varied diversely. As a result, we could confirm that ozone gas was generated successfully and the performance of diamond electrode was stable while $PbO_2$ electrode was disintegrated. Actually we are found that ozone amount increased by lowering the temperature of electrolyte.

The clinical experience with the activated clotting time[A.C.T.] for the control of heparin and protamine therapy during cardiopulmonary bypass in 40 patients between April, 1987 and September, 1987 is reviewed retrospectively. All of patients used with cold blood potassium cardioplegia for myocardial protection under standard cardiopulmonary bypass, priming and perfusate techniques respectively. This study was divided into 2 groups of patients followed by cardiopulmonary bypass time. Twenty patients, within 60 minutes of cardiopulmonary bypass time[group A] were compared with twenty patients, from 60 to 120 minutes of cardiopulmonary bypass time[group B]. Using blood cardioplegia for myocardial protection, Author observed wide variation of A.C.T. in individual response to initial heparinization[2mg /kg] and no requirement of additional heparin during cardiopulmonary bypass until 120 minutes. Total heparin amount during cardiopulmonary bypass was not related to body weight and body surface area in the both groups. After cardiopulmonary bypass, amounts of protamine for neutralization of heparin were more required in group B.

An efficiency of a refrigeration cycle and a reliability of a compressor can be reduced if a refrigerant including excessive lubricating oil is exhausted from a rotary compressor. Thus, the oil behavior inside the compressor should be analyzed to improve the efficiency. A tested rotary compressor has been manufactured with visualization windows at upper parts in this study to investigate the oil behavior using developed visualization techniques. Discharge pipe with level gage has been visualized to investigate discharged oil amount. The oil behaviors inside the compressor and discharging pipe at various operating conditions have been analyzed. The results of the visualization for the discharging pipe have been compared with those of the upper part to confirm the accuracy.
