Abstract: A superconducting rotating machine having a cooler for a rotator is provided. The superconducting rotating machine includes a rotator wound with a superconducting coil, a stator enclosing the rotator and separated therefrom by a predetermined gap, the cooler having a cold head directly attached to the rotator and at least one compressor connected with the cold head, and a flexible coupling disposed between the cold head and the compressor and enabling a cryogenic refrigerant to flow therein. The cold head is directly connected to the rotator, and the cold head and the compressor are driven using the flexible coupling, so that it is possible to prevent vibration of the compressor and enhance cooling efficiency by thermally separating the cryogenic cold head from the compressor.

Abstract: The present invention relates to novel hydrogenases isolated from novel hyperthermophilic strains belonging to Thermococcus spp., genes encoding the hydrogenases, and methods of producing hydrogen using strains having the genes. According to the hydrogen production methods of the invention, a large amount of hydrogen can be produced merely by culturing the strains in specific culture conditions. Thus, the methods of the invention have advantages in that they are more economic and efficient than existing hydrogen production methods and can produce hydrogen even at high temperature.

Abstract: An operation method of an electronic device includes performing a sleep mode and at least one function that is allowed during the sleep mode, if at least one preset condition is satisfied.

Abstract: Example embodiments are directed to a stack-type image sensor including resistance change elements. The stack-type image sensor includes at least two light-sensing layers that detect different color light stacked on different layers. The stack-type image sensor may not require a size of a unit pixel that detects a light color to be less than 1 ?m in order to generate a high resolution color image. As such, resolution saturation may be avoided.

Abstract: The present invention relates to a phosphatidylinositol 3-kinases activity regulator which include the fifth zinc finger domain of FOG2 and which, more specifically, can induce cancer cells to die due to the inclusion of the fifth zinc finger domain of FOG2. Since the death of cancer cells is induced by suppressing the transfer of PI3K signals, the fifth zinc finger domain of FOG2 according to the present invention can be suitably use as a composition for the prevention and treatment of PI3K-related diseases.
