Abstract: A positive electrode active material including a first lithium composite oxide particle including a secondary particle formed by aggregation of one or more primary particles, and a coating oxide occupying at least a part of at least one of surfaces of the secondary particle, grain boundaries between the primary particles, or surfaces of the primary particles, the positive electrode active material satisfying an equation of 1.3?a/b?3.0, wherein a represents a max peak intensity at 2theta=44.75° to 44.80° and b represents a max peak intensity at 2theta=45.3° to 45.6° in X-ray diffraction (XRD) analysis using Cu K? radiation.

Abstract: Disclosed are a separator for fuel cells capable of minimizing the volume of a system and the use of sealants, and a stack for fuel cells, more particularly, a stack for solid oxide fuel cells, including the same. Specifically, by adding a metal sheet having a specific shape, position and size to the separator, the stress applied to the sealant can be uniformized, and thus the oxidizing agent and fuel can be separated and electrically isolated using only a piece of sealant. Therefore, the stack for fuel cells is characterized in that there is no variation in temperature, reactant concentration, power, or the like between respective unit cells, so delamination and microcracks do not occur, the volume is minimized, and the power density per unit volume is very high.

Abstract: Proposed is a 3-dimensional resonant structure-based infrared selective emitter capable of maximizing the infrared selective radiation function by broadening the emissivity in the non-detection bands with resonance phenomena between multiple resonator units at the same time as securing infrared camouflage and energy dissipation-resultant surface thermal stability by reducing the emissivity significantly in the infrared detection band and selectively dissipating energy to the non-detection bands.

Abstract: An apparatus, method, and system for providing information for a wireless network connection using Wi-Fi. Device information for at least one UPnP device is provided from a plurality of wireless devices including the at least one UPnP device, a device information announcement message including the device information for the at least one UPnP device is generated, and the generated device information announcement message is broadcasted. In this way, information on a UPnP device to which to connect a wireless device is provided in advance, and a user can easily perform a network connection.

Abstract: An electronic apparatus is provided.

Abstract: A system and method for displaying document content using Universal Plug and Play (UPnP) is provided. A media server provides meta information corresponding to the document content to a control point if a user request for displaying the document content is received, the control point provides the meta information of the document content to a media renderer that can display the requested document content together with an operation performance command for displaying the requested document content, and the media renderer receives the document content from the media server and renders the document content in accordance with the operation performance command to display the document content on a screen.

Abstract: According to certain embodiments, a method of sharing broadcasting channel information of a mobile device in a Social Networking Service (SNS) includes, if a user comment is posted for a broadcasting program, acquiring broadcasting program information from a Television (TV), uploading the broadcasting program information to a handover broker, acquiring access information that is configured to access the broadcasting program information from the handover broker, and uploading the access information and the user comment to an SNS server.

Abstract: A method and system for sharing content by using context information. A content recommendation server for recommending content to a device includes a context information receiving unit configured to receive position information of a first device from the first device. The server also includes a content registering unit configured to receive a request for registration of content from the first device and register the content together with the received position information. The server further includes a content recommendation unit configured to recommend the registered content to a second device in response to determining that the second device is within a region associated with the received position information of the first device. The region is allocated to the first device and a size of the region is determined based on a number of times that the registered content is provided to another device.
