The method of playing back content using a portable storage includes requesting the portable storage to transmit a right to play back content protected through digital rights management (DRM), receiving the right to play back the content protected through DRM from the portable storage, and informing the portable storage of completion of the playback when a playback of the content protected through DRM using the right is completed.

Abstract: A method and apparatus are disclosed for querying streaming extensible markup language (XML) data comprising: routing elements to query nodes, the elements derived from the streaming extensible markup language data; filtering out elements not conforming to one or more predetermined path query patterns; adding remaining elements to one or more dynamic element lists; accessing a decision table to select and return a query node related to a cursor element from the dynamic element lists; and processing the cursor element related to the returned query node to produce an extracted tuple output.

Abstract: A computer-implemented method for use with an extensible markup language (XML) document includes inputting a high-level mapping specification for a schema mapping; and generating a target XML document based on the mapping. The method may perform schema mapping-based XML transformation as a three-phase process comprising tuple extraction, XML-fragment generation, and data merging. The tuple extraction phase may be adapted to handle streamed XML data (as well as stored/indexed XML data). The data merging phase may use a hybrid method that can dynamically switch between main memory-based and disk-based algorithms based on the size of the XML data to be merged.

Abstract: A method of efficiently managing a, Digital Rights Management (DRM) rights object in a low-performance storage device, which includes causing a host apparatus to divide a DRM rights object into two or more blocks each having a size proportional to an access unit of a low-performance storage device, and transmitting the divided two or more blocks to the low-performance storage device. The access unit is a unit of data reading or data storage in the low-performance storage device.

Abstract: The present invention relates to a method for preparing neodymium-carbon-nanotube and a process for preparing 1,4-cis-polybutadiene utilizing the same and more particularly, neodymium-carbon-nanotube. Neodymium is introduced by coordination with carboxylic acid, which is formed on the surface of carbon nanotube. In 1,3-butadiene polymerization with the neodymium-catalyst comprising the neodymium-carbon nanotube, a particular halogen compound, and a particular organometallic compound in an appropriate ratio, high 1,4-cis polybutadiene having molecular weight of 10,000 to 2,000,000 is produced, which exhibits excellent mechanical properties such as elasticity and durability.

Abstract: The present invention provides a method for preparing a copolymer useful for the manufacture of tires by coupling the ends of a living polymer, obtained from copolymerization of a diene monomers in the presence of an organolithium initiator and a hydrocarbon solvent, with a multi-reactive polysiloxane compound, and subsequently modifying the remaining uncoupled ends of the polymer with an amine compound. The use of the copolymer thus obtained for tire production improves the affinity to silica and greatly enhances the dynamic properties required for tires, such as wet traction and rolling resistance.

Abstract: Disclosed herein are a highly porous ceramic having a high porosity of not less than 60% and a pore density of not less than 108 pores/cm3 fabricated from expandable microspheres and a preceramic polymer, and a method for fabricating highly porous ceramic. The method for fabricating highly porous ceramic from expandable microspheres and a preceramic polymer comprises the steps of: homogeneously mixing a preceramic polymer powder and expandable hollow microspheres, if necessary, a ceramic powder, and molding the mixture to form a molded body; heating the molded body to expand it; curing the expanded molded body; and pyrolyzing the cured molded body. Since the highly porous ceramic has a higher porosity and pore density than conventional porous ceramics, it can be suitably used for various high temperature structure materials, kiln furniture, bulletproof materials, shock-absorbing materials, insulating materials, refractory materials, lightweight structure materials, etc.
