Abstract:
Provided is a fault tracing system and method for remote maintenance. The fault tracing method includes detecting faults by receiving error events or fault diagnosis request messages, generating transactions for the detected faults, tracing the faults according to the transactions, and notifying a client terminal or user of the fault diagnosis results. Accordingly, it is possible to accurately trace a fault even in a home/building network environment complicatedly consisting of various resources.
Abstract:
A method of communicating between an access point (AP) and a station (STA) in a Wireless Local Area Network (WLAN) system is provided. The method includes receiving an association request (AREQ) frame requesting an association, from a STA, the AREQ frame comprising a common association response (C-ARSP) indicator indicating whether the STA has been received common association information for the association between the STA and the AP, determining an association response (ARSP) type for the STA based on the C-ARSP indicator and performing an association response for the ARSP type to the STA.
Abstract:
A semantic search system using a semantic ranking scheme including: an ontology analyzer analyzing ontology data related to a search target to determine a weight value of each property according to a weighing method for property; a semantic path extractor extracting all the semantic paths between resources and query keywords and determining a weight value of each extracted semantic path according to the semantic path weight value determination scheme by using the weight value of each property; a relevant resource searcher traversing an instance graph of ontology based on a semantic path having a pre-set length and weight value of more than an expectation level to search resources that have a semantic relationship with the query keywords and are declared as a type presented in the query; and a semantic relevance ranker selecting a top-k results having the highest rank from among the candidate results extracted by the relevant resource researcher by using a relevance scoring function.
Abstract:
An apparatus and a method for preventing copying of terminal unique information in a portable terminal are provided. The method includes storing a root public key for certifying the terminal unique information and a first model class ID of the portable terminal in an One-Time Programmable (OTP) region, encrypting the terminal unique information and certification information of the terminal unique information for certifying the terminal unique information with a terminal unique value and storing the encrypted terminal unique information and the encrypted certification information thereof, obtaining the certification information based on the root public key if certification with respect to the terminal unique information is requested, and certifying the terminal unique information based on the certification information.
Abstract:
The present invention discloses a bioartificial liver system comprising a fixed-bed bioreactor packed with gel beads containing hepatocytes of an animal, a plasma reservoir, a plasma separator, and an efflux chamber, wherein the plasma reservoir is located at a position higher than the bioreactor, a ventilation filter in contact with atmosphere is provided at the top of the plasma reservoir, and the top of the plasma reservoir is directly connected to the efflux chamber via a connecting line. The inventive system satisfactorily performs the essential liver functions without the problems of gel bead damage or channeling.
Abstract:

A plurality of input keys positioned in the vicinity of the plurality of setup information items, respectively, are displayed on the display unit. A mode input unit selecting one among a plurality of modes in which different digital device functions are performed and a modifier modifying at least one of the setup information items according to at least one among the mode selected by the mode input unit and an input from at least one of the input keys.
Abstract:
A method of reducing power consumption caused by leakage current in an interface circuit between modules that are driven by different power sources is disclosed. The interface circuit includes an output driver that operates by a first power supply voltage in a first mode and does not operate in a second mode in which the first power supply voltage is prevented from being applied, an input buffer that is operated by a second power supply voltage in the first and second modes, and a transmission line that connects an output terminal of the output driver to an input terminal of the input buffer. The interface circuit further includes a current leakage prevention circuit that prevents, in the second mode, a current leakage in the input buffer between a second power supply voltage source that supplies the second power supply voltage and a ground voltage source.
