Disclosed are a spindle motor and a method of manufacturing the same. A base plate is integrated with a bearing housing using an insert molding or insert injection method at the same time when the bearing housing is made of resin, thereby being capable of securing the verticality of a bearing and a pivot assembled with the bearing housing and the base plate, reducing the manufacturing cost, and improving the efficiency of a manufacturing process. The motor includes a rotor, a pivot configured to have one end connected to the rotor, a bearing configured to rotatably support the outer circumferential face of the pivot, and a bearing housing made of resin and configured to comprise a first concave groove for receiving the bearing and a second concave groove for supporting the other end of the pivot.

Antenna switch modules and methods of making the same are provided. In certain implementations, an antenna switch module includes a package substrate, an integrated filter, and a silicon on insulator (SOI) die attached to the package substrate. The SOI die includes a capacitor configured to operate in the integrated filter and a multi throw switch for selecting amongst the RF signal paths. In some implementations, a surface mount inductor is attached to the package substrate adjacent the SOI die and is configured to operate in the integrated filter with the capacitor. In certain implementations, the inductor is formed from a conductive layer of the package substrate disposed beneath a layer of the package substrate used to attach the SOI die.

Disclosed herein is a stent which is inserted into a blood vessel of a patient who has to periodically undergo hemodialysis. The stent includes a wire frame which has a hollow cylindrical structure, and a window which is formed in a predetermined portion of a circumferential surface of the wire frame. The window has no wire therein. In an embodiment, the stent may further a graft which covers the wire frame and the window. The present invention can solve problems not only of deformation of the stent graft which occurs when a hemodialysis needle is inserted into the stent in the conventional technique, but also of patient discomfort when having skin punctured high cost, thrombopoiesis, a risk of recurrence, etc.

A method for indexing a suffix tree in a social network includes: scanning an input string and dividing the string into partitions each having a common prefix; performing no-merge suffix tree indexing on the divided partitions; storing information on the partitions on which no-merge suffix tree indexing is performed; storing suffix nodes of the no-merge suffix tree; and establishing a prefix tree. The performing no-merge suffix tree indexing includes: generating a set of suffixes having the common prefix in the input string; generating a suffix set from the set of suffixes and storing the suffix set; and building the suffix set as a sub-tree.

Disclosed herein is an apparatus and method for providing social magazine information. The method is configured such that an apparatus operating in conjunction with at least one user terminal provides social magazine information to a corresponding user terminal. In the method, a social magazine is dynamically reconstructed according to a context of a user of each user terminal. Customized information corresponding to the user terminal is provided based on the reconstructed social magazine. A community is formed among user terminals which share the reconstructed social magazine, and social magazine information is shared through the formed community.
