  • 1. Objectives This study is purposed to classify treatment and diagnosis of So-gal on the relationship of Sasang Constitutional Medicine. 2. Methods We compared conception, symptoms, mechanism and treatment of Sasangin's So-gal in ${\ulcorner}$Dongyisusebowon${\lrcorner}$ ${\ulcorner}$Gabobon${\lrcorner}$, ${\ulcorner}$Sinchukbon${\lrcorner}$ and ${\ulcorner}$Chobongwon${\lrcorner}$. 3. Result and Conclusion (1) So-gal of Soyangin is general disease, it is important disease of interior heat syndrome. So-gal of Taeumin is troubled by dryness of the lung, category of interior heat syndrome, but it bring about various complication. So-gal of Soeumin is important point that divide seriousness of disease. (2) So-gal is interior heat syndrome, it is related to interior heat syndrome of Soyangin, Taeumin. So-gal of Soeumin expresses conclusion of seriousness regardless of exterior and interior disease. (3) So-gal is related to nature, it is most important disease to Soyangin who is apt to variation of nature.

  • The line-start permanent magnet synchronous motor has a high efficiency and an advantage in constant speed operation regardless of the effect of load variation. However it is difficult to predict the performance of characteristics accurately, because of the unbalanced starting torque with the initial starting position of the rotor and the generation of a break torque. In this paper the dynamic characteristics of the line-start permanent magnet synchronous motor are described and compared with those of the squirrel-cage induction motor through the simulation to find the characteristics of the permanent magnets and the rotor bars in the line-start permanent magnet synchronous motor.

  • Single-dose toxicity of a new phosphodiesterse inhibitor-5, DA -8159, was studied in rats via oral and intravenous routes and in mice via oral route. In addition, genotoxic potential of DA-8159 was investigated by using of the battery of test; reverse mutation test on bacteria, chromosomal aberration test on cultured mammalian cells and micronucleous test on mice.(omitted)

  • The novel 1-(1-benzoylindoline-5-sulfonyl)-4-phenyl-4,5-dihydroimidazolones 2 shows highly potent and broad cytotoxicities. Their cytotoxicities against human lung carcinoma A549, human chronic myelogenous leukemia K562, and human ovarian adenocarcinoma SK-OV-3 are compatible with doxorubicin. Compound 2p (1-[(4-aminobenzoyl)indoline-5-sulfonyl])-4-phenyl-4,5-dihydroimidazolone) exhibits a cytotoxicity that is far more potent than doxorubicin and also exhibits highly effective antitumour activities against murine (3LL, Colon 26) and human xenograft (NCI-H23, SW620) tumor models.

  • The pulse power system has been widely used to many applications. such as E/P(Electrostatic Precipitator), DeNOx/DeSOx power system, ozon generator. etc. A pulse energy efficiency for load depend on the rising time, peak value, pulse duration, impedance matching. etc. The pulse generator generally required for short pulse duration, high peak value was forced to consider its size and economy. In this study, developing a compact pulse generator that applied for Cascading method to be made of two pulse transformer, we compared cascading voltage with no cascading one by applying the pulse energy to load.
