Abstract: The present disclosure relates to an eco-friendly flame retardant fabric and a preparation method thereof and in particular to an eco-friendly flame retardant fabric and a preparation method thereof prepared by sequential surface treatment with two types of solutions. According to the present disclosure, flame retardancy and durability may be improved by surface-treating a flammable natural fiber using an eco-friendly flame retardant.

Abstract: The present invention relates to a superconducting magnet apparatus using movable iron core and induction heating apparatus thereof. The superconducting magnet structure is composed by including a pair of superconducting magnets and a pair of movable iron cores which are symmetrically located with respect to the heating target product located between the superconducting magnets and a part of which move through the cutouts of the superconducting magnets. And the distance from the superconducting magnets is adjusted by moving the movable iron cores. Further, the present invention manufactures an induction heating apparatus by using the superconducting magnet structure.

Abstract: The present disclosure relates to a flexible support apparatus for superconducting magnet in superconducting rotating machine. The present disclosure relates to a flexible support apparatus for superconducting magnet in superconducting rotating machine that includes a superconducting magnet that is located in a rotor body of a superconducting rotating machine, a vacuum container that internally stores the superconducting magnet, a first support that supports the superconducting magnet by being internally attached to the vacuum container, a third support that supports the superconducting magnet by being externally attached to the superconducting magnet, and a second support that is located between the first support and the second support and that supports the superconducting magnet by including a flexible material.

Abstract: A DC reactor consisting of a coil formed of a superconducting material is provided. It is possible to reduce leakage reactance and to increase critical current by using a coil formed of a high temperature superconducting material and forming a first bobbin of the DC reactor as a toroid shape.

Abstract: In a radio communication system of hierarchical cell structure in which macrocells provided by a macro base station and femto cells provided by a femto base station are overlapped on each other, a method and a system for handing over a terminal are provided. To be specific, if load of a serving base station increase or decreases more than a predetermined extent, a method and a system adaptively adjust the handover between macro base stations, between femto base station, or between femto base station and macro base station.
