Abstract: A method of balancing rack voltages of a battery pack having a plurality of racks includes (a) a voltage measurement step of measuring voltages of the racks, (b) a sorting step of sorting the racks in ascending powers based on the voltage values of the racks, (c) a comparison step of comparing a difference between a maximum voltage value and a minimum voltage value with a set voltage, (d) a charging/discharging count step of comparing the voltage values of the racks with a reference voltage to increase a charging or discharging count, and (e) a charging/discharging step of charging or discharging the racks according to the charging or discharging count. In a case in which, at step (c), the difference between the maximum voltage value and the minimum voltage value is lower than the set voltage, the racks are charged with the maximum voltage value without steps (d) and (c).

Abstract: Disclosed herein is a method of balancing rack voltages of a battery pack configured to have a structure in which a plurality of racks is connected in series or in parallel to each other, and a plurality of unit modules is connected in series to each other in each of the racks, the rack voltage balancing method including (a) a voltage measurement step of measuring voltages of the racks, (b) an sorting step of sorting the racks in ascending powers based on the voltage values of the racks, (c) a comparison step of comparing a difference between a maximum voltage value and a minimum voltage value with a set voltage, (d) a charging/discharging count step of comparing the voltage values of the racks with a reference voltage to increase a charging or discharging count, and (e) a charging/discharging step of charging or discharging the racks according to the charging or discharging count, wherein, in a case in which, at step (c), the difference between the maximum voltage value and the minimum voltage value is lower

Abstract: Disclosed are a real time automatic update system and method for disaster damage investigation using wireless communication and a web-GIS (Geographic Information System), which are able to prevent disaster recurrence by effectively acquiring various data associated with a disaster area in disaster investigation, quickly establish a disaster register and enable easy searching by loading corresponding data on the web.

Abstract: The present invention relates to heterodimeric conjugates of neomycin-chloramphenicol, of formula 1, their preparation and their use. Because of their heterodmieric structure, they can recognize both stem and loop of RNA motif and show binding ability to a certain RNA such that they have an enhanced pharmaceutical efficacy and reduced side effect which can be caused by non-specific drugs. For these reasons, they can be effectively used as an antiviral agent, an antibacterial agent or an anticancer drugs.

Abstract: The present invention relates to novel oxazolidinone derivatives represented as following compound I and a process for the preparation thereof. The compounds of the present invention have wide antibacterial spectrums superior antibacterial activity and low toxicity. Therefore, it can be expected to use as novel antibacterial agent. wherein, R1 is alkylcarboxyl group or —CH2R2 (wherein, R2 is OH, argido group, —OR3 (wherein, R3 is C1-4 alkyl, methansulfonyl, p-toluensulfonyl, carboxyl, C1-4 alkylcarboxyl, C1-4 alkylcarbonyl, benzyloxycarbonyl, or imidazolylcarbonyl), or —NHR4).
