  • 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.

  • In order to improve the luminous efficiency in ac PDP(Plasma Display Panel), we have suggested the new structures of sustain electrodes with waffle-type barrier ribs and the discharge current for a given pulse voltage has been decreased by eliminating the electrode area which has nothing to do with visible light emission area compared with conventional structure. As a result, the luminous efficiency was improved about 30% compared with the conventional structure.

  • The purpose of this study is to investigate the recognition of "Jung Pung(中風)" mentioned in "Jae-Byoung-Won-Hu-Ron(諸病源候論)" The conclusion would be summerized as follows. 1. "Pung Byoung(風病)" is a symptom that man was damaged by "Pung Chi(風氣)", which is a wide meaning inclusive of cloudiness of conscious, apasia and the limbs disorder of "Jung Pung(中風)", "Bi 痺symptom", "Yeuk Jeil Pung(歷節風)", the skin disease, psychopathy and leprosy. 2. In cause of "Jung Pung(中風)", this book was received the theory of invasion of "Pung Sa (風邪)" from outside claimed in "Nae Kyoung(內經)", "Kum Gaeu Yo Rak(金?要略)", but in a viewpoint of "Hyel Chi(血氣)", "Young Yui(營衛)" and "Bi Yui Heo Sil(脾胃虛實)", especially, insists on the weakness of "Bi Yui(脾胃)" function. 3. In the pathology of "Jung Pung(中風)", there was a recognition that symptoms appear following each "Jang Bu(臟腑)" invaided and changed by a way of "Kyoung Rak Jang Bu(經絡臟腑)", because "Pung Sa(風邪)" invades the space of the skin, disturbs the circulation of "Hyel Chi(血氣)" in a inner and isn't given out in a outer. 4. Thereare, , , , , in the symptoms of "Jung Pung(中風)" and ", , , , , , in the similar symptoms of "Jung Pung(中風)". 5. The principle of treatement is "getting sweating, helping the insufficent energy and diminishing the sufficent energy", but the presciption isn't mentioned and "Do-in Method(導引法)" was recorded after each symptom because of taking a serious view of "Bo-Yang-Sun-Do(補養宣導)" 6. The prognosis of "Jung Pung(中風)"is suggested in a view of pulse diganosis, symptoms and is bad in case of appearance of no sweating, rigidity, vomitting a bubble and apasia.
