Provided are a method and system for transferring data between a plurality of devices. The method of transferring data from a first device to a second device includes: selecting at least one content; acquiring relevant information about the selected content; storing the acquired relevant information; and providing the second device with the stored relevant information when a communication channel is formed between the first device and the second device.

Method and system for transfering data between plurality of devices

Disclosed are a catalyst for dehydrogenating a paraffinic hydrocarbon and a method of preparing the same, wherein the catalyst is configured such that a sponge-type alumina support having 3D meso/macro pores is directly impregnated with an active metal, thus decreasing the diffusion resistance of a material, realizing structural stability, and maximizing the distribution of the active metal in the support, thereby significantly increasing olefin conversion and selectivity. In this catalyst, the sponge-type alumina support is directly impregnated with the active metal to thus form an active metal layer inside the support having 3D meso/macro pores that are interconnected to each other.

The present invention provides a method for providing a service to a device having an interest in a specific service in a device-to-device (D2D) condition. The method includes: searching for a device which enters into an area managed by a device which provides the specific service; and identifying an interest of the searched device in the specific service and inviting the searched device to participate in the specific service. In the method, by selectively connecting a session based on a service interest, an efficient management in view of an entire network capacity is possible and an advantage of reducing a time for session connection is achieved.

Apparatus and method for providing a specific service

Disclosed is a method for controlling a wireless power transmitter for transmitting charging power to a wireless power receiver. The control method of the present invention comprises the steps of: adjusting the internal impedance of the wireless power transmitter such that the impedance variation occurring when the wireless power receiver is positioned is set to a second impedance variation different from the first impedance variation; applying detection power for detecting the wireless power receiver; detecting the second impedance variation during the application of the detection power so as to detect the wireless power receiver; and changing the impedance variation occurring when the wireless power receiver is positioned from the second impedance variation to the first impedance variation.

Disclosed herein is a method for manufacturing oxide fuel pellets. The method for manufacturing the oxide fuel pellets includes (step 1) preparing nuclear fuel powder containing uranium dioxide (UO2+x, x=0 to 0.20), (step 2) compacting the nuclear fuel powder prepared in step 1 to manufacture green pellets, sintering the green pellets manufactured in step 2 at a temperature of about 1,200&#xb0; C. to about 1,400&#xb0; C. by using an atmosphere gas, and reducing the green pellets sintered in step 3 at a temperature of about 800&#xb0; C. to about 1,000&#xb0; C. by using a reducing atmosphere gas. The method for manufacturing the oxide fuel pellets according to the present invention performs the sintering at a low temperature of about 1,200&#xb0; C. to 1,400&#xb0; C. to manufacture economical and safe oxide fuel pellets that are adequate for the nuclear fuel specification.

A method for acquiring a service category table required for finding a service includes acquiring information on a latest service category table by identifying version information of a service category table from a broadcasting signal received from adjacent devices during a process of searching for a device supporting a service desired among devices, and acquiring a service category table of a latest version by establishing a session connection with a device supporting the service category table of the latest version based on the information. By acquiring the information on the latest service category table, a session connection with only the device providing the desired service is established so that an optimized session connection establishing process can be performed and a total network capacity can be efficiently managed. Also, the latest service category table can be acquired from the session-connected device, and thus a new service can be easily identified.
