Abstract: Provided is a wireless communication device for receiving a mobile broadcasting signal and transmitting/receiving a Bluetooth® signal through a single antenna, which allows separation of the two signals using a difference in their frequency bands. A diplexer separates the signals using different band-pass filters. The signals are respectively input into a mobile broadcasting module and a Bluetooth® module. The wireless communication device allows reception of mobile broadcasting and Bluetooth signals within different frequency bands through a single antenna, thus achieving a compact and thin device with a reduced antenna mounting space.

Abstract: A method and apparatus for setting up a wireless ad-hoc network, the method including: interchanging a terminal identifier and Wi-Fi protected setup (WPS) capability information with other terminals of the wireless ad-hoc network; selecting a role as a registrar or an enrollee based on the interchanged terminal identifier and the interchanged WPS capability information of the wireless ad-hoc network; and optionally registering in the registrar based on the selected role.

Abstract: Provided is an allosteric trans-splicing group I ribozyme whose target-specific RNA replacement activity is controlled by theophylline, wherein the hTERT-targeting trans-splicing ribozyme recognizes mRNA of human telomerase reverse transcriptase (hTERT) as a cancer-specific RNA transcript to bind a theophylline aptamer to an hTERT target trans-splicing ribozyme via a communication module, the hTERT target trans-splicing ribozyme having a verified trans-splicing ability. The allosteric trans-splicing group I ribozyme may be useful to selectively diagnose only cancer cells that express target hTERT RNA, or induce their apoptosis since the activity of the allosteric trans-splicing group I ribozyme is dependently controlled by theophylline to correct target hTERT RNA by the trans-splicing reaction.

Abstract: Disclosed a nuclease-resistant RNA aptamer for inhibiting the replication of HCV replicon. This aptamer is capable of binding specifically to HCV NS5B and inhibiting the proliferation of the HCV replicon, and is composed of at least one sequence selected from a group consisting of SEQ ID NOS. 1 to 4, in which a fluoro group is substituted for 2?-hydroxy of both U (uracil) and C (cytosine) bases, and SEQ ID NO. 4, which is tagged with a cholesteryl group at a 5? end and with idT at a 3? end. The RNA aptamer is useful in the diagnosis and treatment of HCV infection.

Abstract: A dual band antenna unit for a mobile device may include an antenna receiving part, a first antenna part having a first contact point and a second contact point, a second antenna part, a first feed point and a second feed point. The second antenna part may be formed integrally with the first antenna part and may extend from the first antenna part. The second antenna part may be extractably and retractably mounted in the mobile device. The first antenna part and the second antenna part may have resonant frequencies of different frequency bands. When the second antenna part is extracted, the first contact point may contact the first feed point. When the second antenna part is retracted, the second contact point may contact the second feed point. The mobile device may operate in different frequency bands using a single antenna unit, thereby allowing freedom of internal design and meeting the demand for miniaturization.

Abstract: Provided is a method of processing and transmitting transport stream packets and processing the transmitted transport stream packets. A time stamp is generated in a medium access control (MAC) layer based on time information managed by the MAC layer, and a data frame including the transport stream packets is retransmitted based on an algorithm different from that used for a general data frame when a transmission error occurs. Therefore, there is no need to transmit and receive additional synchronization packets in order to precisely transmit the transport stream packets between transmitting and receiving terminals, and it is possible to reduce performance deterioration caused by latency and jitter.

Abstract: The present invention relates to a method for fabricating a semiconductor device. In more detail of the aforementioned method, a first mask layer covering a cell region is formed on an insulation layer in the cell region. Meanwhile, a second mask layer is formed in a peripheral circuit region with a predetermined distance from the first mask layer. The insulation layer is then etched with use of the first and the second mask layers as an etch mask to form a spacer at both sidewalls of each gate line pattern in the peripheral region and simultaneously form a guard beneath the second mask layer. The first and the second mask layers are removed thereafter. Next, a third mask layer opening the cell region but covering the whole regions including a guard region in the peripheral circuit region is formed. A wet etching process is performed to the insulation layer remaining in the cell region by using the third mask layer as an etch mask.

The apparatus includes a diplexer being connected to both a first-frequency communication module and a second-frequency communication module, and separating a first-frequency signal and a second-frequency signal from each other so that the two frequency signals share a single communication route; and a switch unit for performing a switching operation so as to connect a communication route either between the intenna and the diplexer, or between the intenna and a third-frequency communication module. The apparatus may include a controller for generating a control signal in order to control the switching operation of the switch unit, wherein the control signal is used to establish a first mode for transmitting/receiving the first-frequency signal or the second-frequency signal, or to establish a second mode for receiving a third-frequency signal.
