  • This paper presents an equalizer reducing CCI(cell-to-cell interference) in MLC NAND flash memory. The CCI is a critical factor which affects occurring data errors in a cell, when surrounding cells are programed. We derived a characteristic equation for CCI considering write procedure of data that is similar with signal equalizing. The model considers the floating gate capacitance coupling effect, the direct field effect, and programming methods of the MLC NAND flash memory. We verify the proposed equalizer comparing with the measured data of 1-block MLC NAND flash memory. As the simulation result, the equalizer shows an error correction ratio about 60% under 20nm NAND process.

  • Objectives: This study was undertaken to determine if Plantaginis Semen(PS) has a protective effect against $CCI_4$ induced hepatoxicity in Rats. Methods: The experimental groups were divided into Normal group (untreated Group), Control group $(group\;treated\;with\;CCI_4)$, Sample 1 (group treated with 0.1 ml Plantaginis Semen herbal acupuncture in both sides of $G\bar{a}nsh\bar{u}\;(BL_{18})$ after $CCI_4$ treating) and Sample 2 (group treated with feeding of 1 cc Plantaginis Semen extraction after $CCI_4$ treating). Rats were administered orally $CCI_4\;(0.1\;ml/kg)$ for 4 days. In experiments for PS effect, rats of Sample 1 group received 0.lml herbal acupuncture of PS extraction in both sides of corresponding $G\bar{a}nsh\bar{u}\;(BL_{18})$ of human body for 3 days after treated $CCI_4$. Rats of Sample 2 group feeded PS extraction (1cc) for 3 days after treated $CCI_4$. Variation of weight and biochemical assays (AST, ALT, LDH, ALP, total cholesterol, triglyceride, total protein, albumin) were performed. Results: In Control group, $CCI_4$ increased serum AST, ALT, LDH, ALP, total protein, albumin and decreased weight, total cholesterol, triglyceride. Sample 1 and Sample 2 significantly decreased serum AST, ALT, LDH, ALP, total protein, albumin as compared with Control group. Conclusion: These results indicate that PS could be used in prevention and treatment of hepatoxicity. However, precise mechanisms of PS protection remain to be determined.

  • Pharmacokinetics of aucubin, an irdoid glucoside, was compared in rats of experimental hepatic failure(EHF). EHF was induced by CCI$_{4}$ or D-galactosamine pretreatment. This work was designed to find out any differences in the pharmacokinetics of aucubin that may explain the different protective effect of aucubin on CCI$_{4}$- and galactosamine-induced EHF : aucubin reportedly protected CCI$_{4}$-inducing hepatotoxicity effectively, but did not for galactosamine-hepatotoxicity. EHF was induced by intraperitoneal injection Of CCI$_{4}$(0.9ml/kg) or galactosamine(250 mg/kg) to Wistar rats 24 hr before the pharmacokinetic study. The rats were fasted during the 24 hr. Aucubin was iv injected at a dose of 15 mg/kg and the plasma aucubin was assayed by HPLC. There were no significant differences in the pathophysiologies(body weight, liver weight, GTP, hematocrit, blood cell distrbution and plasma protein binding of aucubin) between the two EHF models except GOP which was significantly (p<0.05) higher in CCI$_{4}$-than in galactosamine-EHF. On the other hand, pharmacokinetics of aucubin such as total cleatance(CL$_{t}$), distribution volume at steady-state(Vd$_{ss}$), and mean residence time(MRT) differed significantly(p<0.05) between the models : for example, CL$_{t}$ was increased two fold by CCI$_{4}$, but not by galaclosamine ; Vd$_{ss}$, in galactosamine-EHF was higher than that in CCI$_{4}$-EHF ; MRT was decreased by CCI$_{4}$, but increased conversely by galactosamine. The increase of CL$_{t}$(and decrease of MRT) in rats of CCI$_{4}$-EHF was contrary to the general expectation for the hepatic failure : most of the hepatic failures have been known to decrease CL$_{t}$ of the administered drugs. Whether the difference in the pharmacokinetics is responsible for the different protective effect of aucubin against the two EHF models is of interest. However, much more studies on biliary excretion, urinary excretion, and hepatic uptake in cellular level should be preceded before any conclusions are made on the role of different pharmacokinetics on the different pharmacology of aucubin.

  • This paper presents a modified CCI image interpolation method based on the even-odd decomposition (EOD). The CCI method is a well-known technique to interpolate images. Although the method provides better image quality than the linear interpolation, its complexity still is a problem. To remedy the problem, this paper introduces analysis on the EOD decomposition of CCI and then proposes a reduced CCI interpolation in terms of complexity, providing better image quality in terms of PSNR. To evaluate the proposed method, we conduct experiments and complexity comparison. The results indicate that our method do not only outperforms the existing methods by up to 43% in terms of MSE but also requires low-complexity with 37% less computing time than the CCI method.

  • The effects of Fucoidan extracted from Ulva lactuca on carbon tetrachloride ($CCI_4$)-induced dysfunction in $CCI_4$-posttreated rats were investigated. Ulva lactuca fucoidan (ULF) of 100 mg/kg concentration was intraperitoneally administered into rats at dose of 1 ml/kg for 14 days. On the day 15, 3.3 ml/kg of $CCI_4$ dissolved in olive oil (1 : 1) was injected 12 hours before anesthetization. We examined the levels of glutamate oxaloacetate transaminase (GOT), glutamate pyruvate transaminase (GPT) in serum of rats, superoxide dismutase (SOD) in mitochondrial fraction and catalase (CAT), glutathione peroxidase (GPx), malondialdehyde (MDA) in liver of rats. SOD, CAT, GPx decreased, and GOT, GPT, MDA increased in the $CCI_4$-treated group. But SOD, CAT, GPx increased, and GOP, GPT, MDA decreased in the ULF and $CCI_4$-treated group. These results showed that ULF had the protective effects on the liver dysfunction of $CCI_4$-treated rats.
