Abstract: A method and apparatus for protecting digital content stored in a universal serial bus (USB) mass storage (UMS) device from unlimited distribution are provided. According to the method and apparatus, a UMS device generates a random key according to a request from a user and shows the generated random key to the user, and then, by using the random key, registration data is encrypted. Accordingly, only a USB host that registers the UMS device after the user connects the USB host directly to the UMS device, can freely use digital content of the UMS device, and even if encrypted registration data of the UMS is leaked out, unauthorized devices cannot register the UMS device.

Abstract: A method and apparatus for performing authentication are provided. The method includes: receiving an authentication request signal for requesting authentication from an external device; determining whether authentication has been performed with the external device that has transmitted the authentication request signal; based on the determination, selectively outputting an indication representing that it is necessary to perform authentication with the external device; if the indication representing that it is necessary to perform authentication with the external device is output, receiving an authentication execution command for instructing the execution of authentication in response to the indication; and performing authentication with the external device according to the authentication execution command.

Abstract: The present invention provides a method for manufacturing a printed circuit board and a print circuit board manufactured thereby, in which through holes of a core board are filled by reverse pulse plating so that it allows to manufacture a core board having greater than 100 ?m of a thickness which has been a processing limitation with conventional technologies and form bumps on a thick insulation layer, which has been difficult till now, and thus providing resistance against pressure of paste bumps produced during stacking due to the increased strength of a core board, convenience to join between layers, excellent heat-releasing effect, and collectively stacking of core boards, which was not possible with conventional methods.

Abstract: Disclosed is a three-axial displacement measuring apparatus. The three-axial displacement measuring apparatus includes: a fixation grip fixed to one surface of a hanger supporting a structure to be measured; a universal joint connected to the fixation grip which is capable of rotating by 360 degrees; a link section being connected to the universal joint and having at least one angle sensor; an angle sensor section connected to the link section, for measuring angles; and a three-axial displacement measuring section for calculating three-axial displacement values of the measured structure by using the angle values measured by the angle sensor section.

Abstract: A method and apparatus for generating and updating a license for content and for providing content are provided. The method of generating a license includes generating license signature information for authenticating the license; generating use rule information for controlling the use of the content; generating authentication code information for authenticating a coupon for changing at least a portion of the use rule information; and generating key information required for decrypting the content.

Abstract: A method for etching platinum (Pt) includes etching a platinum layer using a gas mixture including a fluorine (F) containing gas and an inert gas. A method for fabricating a capacitor having a bottom electrode, a dielectric layer, and an upper electrode includes forming the bottom electrode by etching a platinum layer, and forming the upper electrode by etching another platinum layer, wherein the platinum layers are etched using a gas mixture including a fluorine (F) containing gas and an inert gas.

Abstract: A printed circuit board using paste bumps and manufacturing method thereof are disclosed.

Abstract: Provided are a method and apparatus for effectively fixing scrambled content. The method includes checking fixing information for a program map table (PMT) packet of packets constituting the content, the fixing information being used to fix a transformed part of the content; extracting location information of a next PMT packet containing fixing data for fixing the transformed part of the content from the fixing information of the PMT packet; and fixing the transformed part of the content by using the fixing data in the next PMT packet indicated by the extracted location information. Accordingly, it is possible to easily detect a location of the content, which stores the fixing information, thereby expediting fixing of the transformed content.

Abstract: The present invention relates to an efficient snapshot technique based on a mapping for a large logical volume shared in multiple hosts. According to the present invention, problems of time delays in a conventional snapshot technique is solved by employing a FAB and an SSB, which are bits representing whether a COW operation is carried out to a mapping entry. In other words, the present invention solves the problems of delaying a write operation of corresponding volume, which is simultaneously executed when a snapshot is created, until the snapshot creation is completed. Further, in the write operation carried out after the snapshot creation, an operation of determining whether the COW operation is carried out is achieved by reading only an original mapping block by using the FAB and the SSB, without reading out the snapshot mapping block.

Abstract: The invention relates to an agent for the medicamentous treatment of acute and chronic pain, in particular of allodynia and hyperalgesia. Fields of application of the invention are medice and the pharmaceutical industry. A new pharmaceutical composition for the treatment of acute and/or chronic pain, in particular allodynia and hyperalgesiais provided, the pharmaceutical composition comprising calcium channel blockers which are suitable for blocking voltage-dependent calcium channels, in particular of the T-type, more preferably the CaV3.2 channel and/or of the L-type. Mibefradil and dihydropyridines can, for instance, be used as calcium channel blockers.
