Abstract: The present invention relates to a bending adjustment apparatus using a curved bar, a bendable electronic device including the same, and a method for adjusting bending of the electronic device. The bending adjustment apparatus according to the present invention includes: a guide unit attached to a flat panel member made of a flexible material; at least one curved bar extending in a curved shape and rotatably installed in the guide unit; and a power transmission drive unit configured to rotate the curved bar so as to adjust a tensile force applied to the flat panel member corresponding to a curved shape of the curved bar. Accordingly, the degree of bending of the panel may be controlled by adjusting an angle formed by the curved direction of the curved bar with the panel in a state in which the bent-type curved bar is coupled to the flat panel member such as a display panel, and the curvature of the panel may be adjusted to a desired degree by controlling the rotation of the curved bar to an arbitrary angle.

Abstract: Disclosed is a flexible electronic device, including: a body made of a flexible material; a display unit; a flexible circuit board; a bending adjuster having a first plate that maintains a flat shape at room temperature, and a second plate that maintains a bent state at a specific temperature or more and having an elastic force larger than that of the first plate in a superelastic state, and is configured to adjust bending of the body by these plates, such that it is possible to improve reality of an image on a display unit by controlling the overall electronic device to be bent at a predetermined angle, more stably maintain a bent state and a flat state, reliably prevent a display unit and a flexible circuit board from being damaged, and stably maintain the bent state and the flat state despite using for a long period of time.

Abstract: An embryonic stem cell line derived from a nucleus-transferred oocyte prepared by transferring a nucleus of a human somatic cell into an enucleated human oocyte may differentiate into various desired cell types.

Abstract: An optical DPSK signal demodulator includes a signal separator that separates an optical signal into an input optical signal and an output optical signal in a signal optical path. First and second reflectors are provided at a predetermined interval and reflect the optical signals with a predetermined time delay to have substantially the same intensity. A phase shifter is provided between the first and second reflectors and configured to allow the optical signals reflected from the first and second reflectors to have a phase difference.
