Abstract: A three-terminal synaptic device includes a substrate; a source electrode and a drain electrode which are provided on the substrate and spaced apart from each other. The three-terminal synaptic device further includes: a channel layer provided on the substrate, the source electrode, and the drain electrode; an ion reservoir layer which stores active ions; a gate electrode provided on the ion reservoir layer; and an ion barrier layer disposed between the ion reservoir layer. In particular, the channel layer controls movement of active ions between the ion reservoir layer and the channel layer. The three-terminal synaptic device inhibits rapid movement of ions.

Abstract: An exhaust gas recirculation (EGR) control method applied with a humidity sensor for preventing condensation to prevent corrosion caused by exhaust gas in a vehicle, may include a first step of measuring a temperature, humidity, and atmospheric pressure of intake air which is introduced from the outside of the vehicle and flows into the EGR; a second step of determining a molar fraction of water vapor included in the intake air by a combustion equation of the water vapor and determining water vapor pressure in the EGR; and a third step of opening an EGR valve so that EGR gas flows when the water vapor pressure in the EGR is lower than saturated water vapor pressure in the EGR.

Abstract: This invention relates to a process for producing exopolysaccharide from submerged mycelial culture of mushroom and more particularly, to the process for improving the exopolysaccharide production from the mycelia using the different bistage pH control technique comprising the steps of; (1) a process for the production of mycelia whose pH conditions in a batch medium are kept constant at 2 to 6 at the initial pH, while adding ammonium ion to the medium, and (2) a process for the production of exopolysaccharides whose pH conditions in a batch medium containing the mycelia are adjusted to 3 to 7. According to this invention, the optimized mycelial morphology and rheological properties in the culture media can lead to EPS production in more efficient and stable manner.
