  • Potassium ($K^+$) is one of the most abundant cations in higher plant. It comprises about 10% of plant dry weight and it plays roles in numerous functions such as osmo- and turgor regulation, charge balance of plasma membrane and control of stomata and organ movement. Several potassium transporters and potassium channels regulate $K^+$ homeostasis in response to $K^+$ uptake systems. In this review, we describe the biological, biochemical and physiological characteristics of shaker like potassium channels in higher plant. Especially, we searched the rice genome databases and analysized expressed genes, genome structures and protein domain characteristics of shaker like potassium channels.

  • Bio-electronics has been considered as one of the most appropriate candidates to overcome the frequently encountered problems in the development of future electronic devices. It has some advantages such as ultra fast electron transfer rate and high-energy efficiency compared with the silicon-based electronic devices. In silicon-based electronics, there are some of limitations of manufacturing process and physical problems. Bio-electronics can overcome the limitation and problem of silicon-based electronics. Bio-electronics has possible application areas as biosensor, biochip, bio-transistor and bio-computer. In the future, bio-electronics can substitute the silicon-based electronics.

  • In this study, to investigate the feasibility of malodorous substance and organic matter removal by digest sludge in sewage treatment plants, ammonia, methyl mercaptan(MMC), and hydrogen sulfide($H_2S$) in a reactor submerged with BIO-CLOD(BIO-CLOD) and a reactor not submerged with BIO-CLOD(Non BIO-CLOD) were measured at 24 hours, 48 hours, and 72 hours after the submergence of BIO-CLOD. Whereas the reactor in which BIO-CLOD was submerged showed an ammonia removal rate of 48% and high $H_2S$ and MMC removal rates exceeding 98% in 24 hours, the reactor in which BIO-CLOD was not submerged showed an ammonia removal rate of 45%, an $H_2S$ removal rate of 71%, and an MMC removal rate of 84% in 24 hours indicating the possibility of removal of malodor using BIO-CLOD. A nitrification was shown in which ammonia concentrations decreased over time while nitrate nitrogen concentrations increased and sulfur based malodor components were oxidation decomposed indicating that BIO-CLOD had effects to increase sulfate concentrations in the solution and that sulfate concentration increases and atmospheric $H_2S$ removal rates were correlated with each other. With regard to decreases in organic matter in reactor effluents, BIO-CLOD did not affect in a short period of time and when reactors were operated with HRT 12 hours and HRT 24 hours, HRT 12 hours was considered desirable in terms of economy.
