This paper describes the design and control technique of a plasma power supply for 3kW LCD cleaning. 3kW plasma is used as a power supply to supply power to DBD (Dielectric Barrier Dischatge) that cleans a large area of LCD. In order to supply power stably during DBD discharge, LC resonance type topology is applied. The validity of the proposed topology is verified through experiments.

This paper describes the design method of 1kW low-temperature plasma power supply and low-temperature torch. Low-temperature plasma is used in systems requiring dry cleaning at low temperatures, such as batteries, where the temperature is less than 50℃. Plasma power supply is designed and manufactured, and the validity of low-temperature plasma generation is verified through experimentation with low-temperature plasma.

N/A We studied several viral replication markers of hepatitis B virus in patients with chronic hepatitis B and hepatocellular carcinoma to evaluate the clinical significance of thesemarkers in serum. The patients comprised of 43 males and 8 females, and ages from 17 to 64 (mean: 34) years. All patients were sero-positive for hepatitis B surface antigen (HBsAg). Histologically, 36 patients showed chronic active hepatitis and 15 showed hepatocellular carcinoma. The viral replication markers tested were hepatitis B e antigen (HBeAg), antibody to hepatitis B e antigen (anti-HBe), Immunoglobulin M antibody to hepatitis B core antigen (IgM anti-HBc), DNA polymerase and hepatitis B virus deoxyribonucleic acid (HBV-DNA). The results were summerized as follows. 1) The younger the patients, the higher was the positive rate of HBeAg; the older the patients, the higher was the positive rate of anti-HBe. 2) There was a reverse correlation between the age and the level of serum alanine aminotransferase (ALT); the younger the patients, the higher was the titer. But no correlation was noted between age and the level of serum aspartate aminotransferase (AST). 3) The histologic findings of the liver tended to be more severe in older patients. The patients with hepatocellular carcinoma were the oldest group. 4) The positive rate of HBeAg was higher in patients with chronic hepatitis than in patients with hepatocellular carcinoma. but there was no difference between these two groups in the positive rate of IgM anti-HBc. 5) The positive rate of HBV-DNA and DNA polymerase was 63% and 35%, respectively, and their titers were significantly low. 6) There was no significant correlation between the positive rate of HBeAg, IgM anti-HBc, HBV-DNA, and DNA polymtrase. On the basis of these findings, it is suggested that the natural history of chronic hepatitis B of Koreans might be different from that of Caucasians; the positive rate and the titers of the viral replication markers were lower in Koreans.
