Abstract: The present invention relates to a nucleic acid isolation buffer composition, a nucleic acid isolation kit in which a membrane filter comprising same is provided, and a nucleic acid isolation method, wherein the nucleic acid isolation buffer composition has excellent compatibility with membrane filters of various materials, and enables the excellent isolation of nucleic acids from various samples, and, particularly, a nucleic acid isolation kit comprising same enables column-based one-tube PCR, and a nucleic acid isolation method using same enables the direct application of the membrane filter, on which nucleic acids are immobilized, to PCR without a separate elution process. Therefore, the nucleic acid isolation composition, the kit and the isolation method according to the present invention can be effectively used in rapid diagnosis onsite.

Abstract: The present disclosure relates to a portable RT-PCR device and an RT-PCR measurement method that uses the portable RT-PCR device.

Abstract: A method for producing an optically anisotropic film. The optically anisotropic film produced using this method has a reverse wavelength dispersion property, which can control retardation deterioration at high temperature, and can be used in polarizing plates and display devices.

Abstract: A device for electrically connecting a microphone mounted on a flip cover to an audio circuit of a telephone body. The flip cover is detachable from the telephone body when an excessive force is applied thereto. A hinge apparatus includes two hinge modules each including a hinge housing, a hinge shaft having a protrusion at an end and a shaft at another end, being assembled into the hinge housing; conductive means fixedly pressed into a through hole formed along an axis of the hinge shaft; a cam hinge having opposing protrusions and opposing indents formed alternately at one side, engaging with the hinge shaft, and a through hole formed along the axis of the hinge shaft; a hinge cover mounted so as to cover an end of the hinge housing, the hinge cover having a through hole formed along the axis of the hinge shaft, through which an electric wire passes; and a coil spring intervening between the cam hinge and the hinge cover to provide an elastic force.
