Abstract: The present invention relates to a method for preparing a two-dimensional hybrid composite that is capable of solving the problems with the two-dimensional plate type materials, that is, step difference, defects, stretching, etc., that occur as the second-dimensional plate type materials overlap with one another. The present invention provides a method for preparing a two-dimensional hybrid composite that includes: (a) preparing a first plate type material in the solid or liquid state; (b) mixing a second plate type material with the first plate type material, the second plate type material being thinner and more flexible than the first plate type material; (c) mixing a solid or liquid binder with the first and second plate type materials to make the first and second plate type materials partly contact with or apart from each other; and (d) solidifying a composite formed by the steps (a), (b) and (c).

Abstract: The present invention relates to a system and method for issuing an authentication key for authenticating a user in a CPNS environment. The system comprises a user terminal, a gateway and a CPNS device. The user terminal is equipped with a short-range wireless communication function, requests the gateway to register terminal information including an ID and password, encrypts the terminal information including the ID and password using the password, transmits an authentication request signal including the encrypted terminal information to the gateway, and receives an authentication key generated by a CPNS device. The CPNS device stores the terminal information, performs user authentication by decrypting the encrypted terminal information in response to the authentication request, generates an authentication key for the CPNS when a user is authenticated, encrypts the generated authentication key using the password, and transmits the encrypted authentication key to the user terminal through the gateway.

Abstract: The present invention relates to a system and method for outputting contents in a CPNS environment, comprising: a user terminal for searching for a contents playback terminal including a wireless communication unit supporting CPNS, sharing the contents with the contents playback terminal by connection to the user terminal through a short-range communication network, decoding corresponding contents in response to a contents playback request received from the user terminal, converting the corresponding contents into frequency modulation (“FM”) data, transmitting the converted FM data to a contents output device for demodulating the FM data received from the contents playback terminal and outputting the demodulated FM data in real-time through a contents output device.

Abstract: The present invention relates to a system and method for providing contents through a network in a device incapable of connecting to a network, the system including a contents playback device provided with an audio output port, for playing back the contents; and a dongle device supporting CPNS and attached to the audio output port to enable the contents playback device to operate as a device capable of connecting to a network, for capturing and encoding contents outputted from the contents playback device and providing an external user terminal with the encoded contents through the network. Accordingly, according to the present invention, the contents playback device incapable of connecting to a network is enabled to operate as a device capable of connecting to a network only by attaching the dongle device, and since the dongle device encodes the contents (e.g.

Abstract: The present invention relates to a system and method for outputting contents in a CPNS environment, and the system for outputting contents in a CPNS environment comprises: a user terminal for searching for a contents playback terminal supporting CPNS, sharing the contents with the contents playback terminal by receiving contents information from the searched contents playback terminal and downloading at least one piece previously stored contents to the contents playback terminal, and requesting playback of contents selected by a user among the shared contents; the contents playback terminal for sharing the contents with the user terminal by connecting to the user terminal through a short-range communication network, and outputting corresponding contents through a contents output device in response to a contents playback request received from the user terminal; and the contents output device for outputting the contents received from the contents playback terminal.

Abstract: Disclosed herein are a fluorine-doped tin oxide (FTO) transparent conductive film glass used for defogging purposes comprising a glass layer, a dielectric barrier layer, a functional layer, a metal electrode layer, a plastic intermediate layer, and a glass layer, stacked in this sequential order, in which the functional layer comprises an FTO transparent conductive film having a molar ratio of F to Sn in the range of 0.5 to 2, mainly including a (301) crystal plane and being formed by a spray coating method, and a method of fabricating the same.

Abstract: The present invention provides a method of preparing a colorless and transparent FTO conductive film using a polymer post-treatment process, in which a polymer is coated or bonded to an FTO film having a low transmittance due to optical coloring, thereby increasing the transmittance.
