A method of controlling a display device including a touch screen is provided. The method includes setting an application execution space having one or more sub spaces in which windows executing applications are arranged, arranging windows corresponding to one or more applications which are being executed in the sub spaces of the set application execution space, displaying a first sub space corresponding to one of the one or more sub spaces on the touch screen, receiving a data sharing command for sharing data included in a first window arranged in the first sub space, and sharing the data to be shared by a second window arranged in a second sub space corresponding to one of the one or more sub spaces based on the data sharing command.

Disclosed are an apparatus and a system for managing circadian rhythm. The apparatus includes an illuminance measuring portion which measures a bio illuminance value of external light using a circadian lambda filter which passes the external light along according to a circadian rhythm sensitivity curve and a visual lambda filter which passes the external light along according to a visual sensitivity curve, a controller which outputs a control signal for reinforcing a user's circadian rhythm on the basis of the bio illuminance value, and a circadian rhythm reinforcing portion which emits light of a circadian wavelength band toward the user according to the control signal.

Methods for producing nanoparticle thin films are disclosed. According to one of the methods, a nanoparticle thin film is produced by modifying the surface of nanoparticles to allow the nanoparticles to be charged, controlling an electrostatic attractive force between the charged nanoparticles and a substrate and a repulsive force between the individual nanoparticles by a variation in pH to control the number density of the nanoparticles arranged on the substrate.

An apparatus and method for determining contents information corresponding to a Rights Object (RO) by transmitting information on contents together when the RO is moved from a mobile device to a memory card or a smart card or when the RO is moved from the memory card or the smart card to the mobile device are provided. The apparatus includes a meta information manager for determining information on contents corresponding to the RO when the RO is moved, and for generating meta information containing the determined contents information, and a controller for providing control to transmit the RO and the meta information generated by the meta information manager to a portable storage device. Accordingly, the conventional problem can be solved in which information on contents cannot be determined by using a Contents IDentifier (CID) if the RO does not exist together with the contents.
