Abstract: The present disclosure relates to an antibody binding specifically to CD55 or an antigen-binding fragment thereof; and a composition for preventing, treating and/or diagnosing cancer containing the same. The antibody of the present disclosure may be used as an effective therapeutic composition for various CD55-mediated diseases since it shows high binding ability and inhibitory effect for the CD55 protein which promotes tumor growth by inhibiting the complement immune mechanism. In addition, the antibody of the present disclosure may be usefully used as an effective therapeutic adjuvant that fundamentally removes drug resistance and remarkably improves therapeutic responsiveness in various diseases in which resistance to therapeutic agents with CDC (complement-dependent cytotoxicity) as a mechanism of action has been induced due to overexpression of CD55.

Abstract: A method and system of measuring a domain specific spatial ability required in the field of architecture or interior design are disclosed. In the method, in order to measure a spatial ability of a user, one or more of a mental rotation measurement and a spatial visualization measurement for the user is first performed. Then, the spatial ability for the user is evaluated according to a result of performing one or more measurements. Then, the evaluated result is provided to the user as a domain specific spatial ability required in the field of architecture or interior design. Here, the mental rotation measurement is performed by measuring a rotation state estimation ability for a 3D figure, and the spatial visualization measurement is performed by measuring ability of translating 3D spatial information into 2D spatial information and an ability of translating a 2D spatial information into a 3D spatial information.

Abstract: An electric device includes a communication unit to communicate with at least one of a gateway and a plurality of other electric devices, and a controller to broadcast a request signal for searching for a gateway, communicate with the gateway on the basis of a search response signal after transmission of the gateway response signal from at least one of the gateway and the plurality of other electric devices, and transmit a registration request signal to a power management unit through the gateway. Thus, the electric device can be automatically registered/re-registered in the electric device or be deleted from the electric device, a power management system and electric devices can be easily managed. If the user moves the electric device from a current position to another position, the power management system recognizes the movement and informs the user of the recognition result.
