Abstract: Provided is a battery discharge apparatus, which includes a main control unit; a first discharge unit configured to discharge a battery from a discharge start voltage to a discharge completion voltage under control of the main control unit; a second discharge unit configured to discharge the battery from the discharge completion voltage to a reverse potential voltage under the control of the main control unit; and a short-circuit switch configured to short-circuit the battery under the control of the main control unit when a voltage of the battery is increased from the reverse potential voltage to become 0 V.

Abstract: The present disclosure provides a current control-type battery discharging apparatus including: a plurality of power switches connected to one terminal of a battery; at least one current feedback control circuit configured to apply at least one control signal to the plurality of power switches; at least one current measurement resistor connected to the plurality of power switches and the other terminal of the battery; and a microprocessor configured to supply at least one reference signal to the at least one current feedback control circuit.

Abstract: The present invention relates to a composition for viral RNA extraction and a viral RNA extraction method using the same, wherein various contaminants (e.g., fungi, bacteria, pollens, etc.) can be effectively removed from samples and thus the diagnosis of sample-derived viruses can be attained more sensitively, and more cheap reagents compared with existing compositions for RNA extraction are used and thus the scales of diagnosis tests of disease-mediated viruses and various monitoring programs can be further enlarged, thereby contributing to public health.
