Abstract:
Provided are a main-memory resident object-relational database management system (ORDBMS) and a method of deleting a class instance using the ORDBMS. The method includes obtaining a mutual exclusive lock for a class to be deleted as per the query and a child class inheriting from the class when a query of deleting an instance is input from a database access application program, and deleting the instance from the class and at least one instance related to the instance from its child class using OID reference.
Abstract:
The present invention relates to a long-acting human follicle-stimulating hormone formulation having improved in vivo duration and stability, comprising a human follicle-stimulating hormone conjugate that is prepared by covalently linking human follicle-stimulating hormone with an immunoglobulin Fc region via a non-peptidyl polymer, and a preparation method thereof. The long-acting human follicle-stimulating hormone formulation of the present invention maintains in vivo activity of human follicle-stimulating hormone at a relatively high level and remarkably increases the serum half-life thereof.
Abstract:
An apparatus and method of improving the quality of a speech codec are provided. In the method, a first energy of a signal decoded by a low-band codec is calculated, and a second energy of a signal decoded by a low-band enhancement mode is calculated. Then, when the first energy is less than a first threshold value or less than a product of the second energy and a second threshold value, a size of the decoded signal is scaled. Accordingly, generation of a quantization error with respect to a silence segment is reduced.
Abstract:
An access point (AP) measures a congestion level of a transmission channel representing a collision probability between frames at a channel busy duration and transmits the congestion level to a terminal. Therefore, the terminal extracts a congestion level that is included in a frame that is received from the AP through a scan process for searching for an AP to which the terminal is to connect. The terminal selects an AP to connect from at least one AP based on the extracted congestion level of the transmission channel.
Abstract:
An apparatus, electronic apparatus and method for adjusting jitter buffer is provided. A previous jitter buffer size based on a jitter buffer size determined according to an adaptive jitter buffer size calculation algorithm is applied in predicting a jitter buffer size of future time such that the predicted jitter buffer size is applied to obtain a jitter buffer size of a valid time. The audio quality of the speech transmitted over a packet switched network is enhanced.
Abstract:
Provided is a vehicle data providing apparatus supporting to easily generate vehicle internal communication data at the development stage of a product to perform a test. According to an aspect, there is provided a vehicle data providing apparatus including: a vehicle data analyzer configured to analyze a vehicle data file that is used in a vehicle, and to provide a reference data graph about reference data included in the vehicle data file; a vehicle data changing unit configured to receive a user input signal for changing the reference data, and to change related data associated with the reference data based on the reference data graph; and a test data file generator configured to generate a vehicle data file for test, including the changed reference data and the changed related data.
Abstract:
A fixed mobile convergence terminal using a wideband voice codec is provided. The fixed mobile convergence terminal includes a communication unit configured to connect to a network, and a control unit configured to download a wideband voice codec identical to a wideband voice codec of an opposite party terminal from a call control server in a call setting with the opposite party terminal through the communication unit, so that a high-quality voice call function is achieved.
Abstract:
A method for the mass production of human coagulation factor VII. The method includes a) providing an expression vector carrying i) a dihydrofolate reductase promoter devoid of one or more CCGCC repeat sequences from the GC-rich region thereof and a dihydrofolate reductase (DHFR) gene operably linked thereto and ii) a cytomegalovirus (CMV) promoter and a human coagulation factor VII gene operably linked thereto; b) obtaining a transformed a host cell line containing the expression vector; and c) culturing the transfected host cell in the presence of a dihydrofolate reductase inhibitor to select cells which express human coagulation factor VII with high efficiency; and d) adding sodium butyrate to the selected host cells.
Abstract:
The present invention relates to a message service method and a message service system. The message service method receives a message and a message transmission request from an open service application user and transmits the message to an appropriate transmission infrastructure such that the message arrives at a destination terminal. To achieve this, the message service system includes an open service application server which sends the message and the message transmission request, an open service gateway which reconstructs the message as one of a short message, a WAP Push message and a multimedia message through message analysis, and transmission infrastructures which transmits messages.
Abstract:
An apparatus and method for testing conformance of service choreography are provided. The apparatus for testing conformance of service choreography analyzes an architecture and an operation between web services cooperating on a distributed network to test conformance of a choreography application into which the web services are combined, on the basis of a service choreography specification.
