This paper presents the experimental results on the 3-electrode DC-PDP which has a common electrode to improve the PDP life cycle. The measured DC characteristic proves the effectiveness of common electrode absorbing about half of discharge currents. The waveforms for pulse memory operation of3-electrode PDP without crosstalk could also be determined from the I-V characteristics. The pulse memory drives of 8*8 cell array show the frequency response fo memory margin and the luminance efficiency of 3-electrode PDP are quite different from genrally known characteristics of 2-electrode DC-PDP.

Recently great efforts and investment have been made in order to evaluate concrete durability by steel corrosion. But most of study is relatively or qualitatively estimated, therefore it has a great limitation in evaluating a remaining service life of concrete. In this research, steel corrosion rate was measured quantitatively by polarization resistance method and multi-regressed considering chloride, carbonation, coverage depth, relative humidity, W/C, and the use of deicing salts. And a half cell potential method was used at th same time for the purpose of comparing with polarization resistance method.

We analyzed the author's productivity and cited literatures to assess research activities of medical scientists and scientific properties of medical research in Korea by bibliometric research methods. We tested applicability of Lotka's law and analyzed the author's productivity by means of Brookes graphic model. And we measured core journals, aging factors and half-life in medical literatures by the Bradford's law and the law of obsolescence.

The interaction between nalidixic acid and probenecid was studied pharmacokinetically in rabbits. The blood level and the area under the concentration curve(AUC) of nalidixic acid administered orally in dose of 100mg/kg was elevated by the coadministration of probenecid. Probenecid inhibited both the urinary excretion and the biliary excretion of nalidixic acid. Therefore, biological half-life of nalidixic acid was prolonged by the coadministrarion of probenecid. It was considered that the coadmini-stration of probenecid is more desirable than the single administration of nalidixic acid for the therapeutic effect.

The phormacokinetics of acetaminophen were investigated in rabbits with folate-induced renal failure. The blood level, the area under the blood concentraction curve(AUC) and the biological half-life were increased significantly, and the urinary excretion was decreased significantly as compared with those of normal rabbits. Serum creatinine concentration and AUC, creatinine clearance and renal clearance have linear relationship respectively. Dosage regimen of acetaminophen was considered to be adjusted in renal failure.

Many Policies were made to increase women's employment since the latter half of the 1980s in Korean. But work-family conflict of married women can not be solved without reducing the household work load, because all of Korean wives have the responsibilities of household work. So this study aims to establish the supporting system of household work in the women's policies. For this purpose this study examine the actual conditions for supporting the household work. And supporting system and strategies for policy making related to household work and suggested. Supporting system includes arrangement in household raise in social consciousness improvement of market circumstance establishment of relating acts and public facilities.

Since streptozotocin has been known to be chemically stable only under acidic condition(pH 4), the spontaneous degradation and cellular uptake of streprozotocin in neutral incubation medium was determined by chemical assay. Streptozotocin levels in both phosphate buffered saline (pH 7.4) and Krebs-Henseleit buffer (pH 7.4) decreased with a half life of about 2 hours. The presence of erythrocytes or pepatocytes under the same buffers did not affect the streptozotocin degradation rate at all. However, streptozotocin levels in plasma isolated from rats decreased rapidly compared to those in neutral buffers.

We used a multiplex PCR primer set composed of 11 microsatellite (MS) markers and two sexing markers for gender detection. Genomic DNA extracted from hair roots of 3,510 Hanwoo were genotyped. Based on the 11MS markers, no animals had identical genotypes(TGLA227, BM2113, TGLA53, ETF10, SPS115, TGLA122, ETH3, ETH225, BM1824 and INRA23). The expected probability of identity among genotypes of random individuals (PI), the probability of identity among genotypes from random half-sibs ($PI_{half-sibs}$) and among genotypes of random individuals, and the probability of identity among genotypes from random sibs ($PI_{sibs}$) were estimated as $1.31{\times}10^{-23}$, $2.52{\times}10^{-16}$and $1.09{\times}10^{-6}$, respectively using the API-CALC program, version 1.0. We successfully completed the genotype analysis of 3,510 Hanwoo with a 3.93% genotyping failure rate. It was revealed that extracting DNA from the hair root was a time-efficient and cost-effective method to collect specimens for DNA isolation from live animals. This method also minimized stress for the animals during specimen collection. Among the hair roots from the back, belly, upper tail and lower tail, 5~13 hair roots of the lower tail led to the best genotype analysis results. Finally, we established a 96-well-format method of DNA preparation applicable for high- throughput genotype analysis.
