Abstract: A method for detecting a modulator that can regulate biological and/or physiological activity of a cellular component is provided. The method can detect a modulator, after determining whether there is a competitive reaction between a reference substance and a modulator toward the cellular component in a cell by imaging a magnetic pattern magnetized in a direction of a magnetic line of force and a pattern of a label bound to the cellular component. The method has a benefit that since the reaction of a cellular component with a reference substance and a modulator such as a drug occurs in a cell, the competition reaction between the reference substance and the modulator toward the cellular component can reflect the real metabolism occurred in a live cell. It can also allow the result of interaction between the cellular component and the modulator such as a drug to be visualized and to be identified directly in a live cell.

Abstract: A method and apparatus for determining a location of a User Equipment (UE) in a communication system. A Base Station (BS) connected to a plurality of antennas by cable receives from each of the antennas reception signal information related to an uplink signal transmitted from the UE, identifies an antenna having a partial service area in which the UE is located, using the reception signal information, and determines the partial service area of the identified antenna to be the location of the UE.

Abstract: An implantable tube to be implanted in a human body so as to be used as a circulation path, and a coating method thereof are disclosed. The implantable tube is a structure with a lumen coated with a bioactive material containing a material promoting fusing of the structure implanted in the body with ambient tissues. When the structure coated with a bioactive material is implanted in the body, the reaction of fusing the structure with ambient tissues can be promoted to shorten a stabilization period required until dialysis begins. In addition, since a chemical drug, medicament for inducing the generation of a growth factor promoting fusing of the structure with ambient tissues, is used, the structure can be easily coated.

Abstract: An apparatus and method for determining a network delay and scheduling a service based on the delay are provided. The method includes determining information about a first time at which data is transmitted, determining information about a second time at which the data is received, determining a time delay using the first time and the second time, and scheduling a service based on the time delay. Because scheduling of service is based on a determined time delay, radio resources are more efficiently used.

Abstract: A method for coating bioactive material and a structured coated with a bioactive material are disclosed. The bioactive material coating method includes: flowing a coating solution, produced as a bioactive material is dissolved in a mixed solvent, inside a structure having a lumen; and coating the bioactive material on at least one of inner and outer surfaces of the structure, with different concentrations. The mixed solvent is mixed with two or more solvents having different features. The occurrence of the strangulation of blood vessels and inflammation can be reduced. An increase in the size of the myofibroblast is not suppressed. The coating solution is produced as a medication is dissolved in a mixed solvent, where the mixed solvent is produced as a polar solvent and a nonpolar solvent are mixed with each other at a certain ratio.

Abstract: The present invention relates to an anti-cancer composition, which comprises a sulfur-containing compound thiacremonone as an active ingredient. The active ingredient induces the death of cancer cells by apoptosis through the action of specific inhibition of the activity of NF-?B. The composition can be effectively used in the treatment or prevention of cancer.

Abstract: A location information tagging method and system for location-based services in a wireless communication system are provided. In the method, if it is determined that a service request message received from a device is being sent to an application server for providing a service based on a location of the device, location information about a base station is tagged to the service request message. The service request message with the tagged location information is transmitted to the application server. Therefore, the application server can obtain location information about the device by merely depending on the message received from the device without referring to a conventional location service server. This reduces a service response time and also rapidly offers a location-based service.

Abstract: Discloses is a method for providing a packet data service in a wireless communication system. A packet data service node (PDSN) or a home agent (HA) allocates an IP (Internet Protocol) address to a mobile station and then registers the allocated IP address information in a DNS (Domain Naming System) server along with a domain name of the mobile station. Alternatively, upon receiving an accounting request message from the packet data service node, an AAA (Authentication, Authorization and Accounting) server registers the IP address information of the mobile station in the DNS server in association with the domain name of the mobile station. Thus, a correspondent node (CN), though it does not recognize the IP address of the mobile station, can access the mobile station using the domain name.

Abstract: Disclosed herein are a tube for arteriovenous anastomosis useful in hemodialysis patients and an insert for use in medicinal operation in the body. The tube or the insert are repetitively treated with a medicament on the surface thereof, which provides stable communication between an artery and a vein of a patient under hemodialysis and can greatly reduce stenosis at arteriovenous connections by releasing the medicament at a suitable rate over a prolonged period of time.

Abstract: Provided is a coordinate conversion apparatus and method capable of removing an accumulation position error when output pixel coordinates are obtained from input image coordinates by using an inverse-mapping technique. In the coordinate conversion apparatus, an output-size register for storing a size of an outputted image, and an input-size register stores a size of an image inputted from an outside. An adder adds, among a quotient and a remainder from dividing the size of the image stored in the input-size register by the size of the image stored in the output-size register, the remainder to the size of the image stored in the input-size register. An accumulation register stores the added value calculated by the adder. A decode logic unit obtains a position between input samples from which an output pixel is re-sampled, by comparing an output value of the accumulation register with an output value of the output-size register.

Abstract: Disclosed herein is a hemodialysis tube treated with a medicament on the surface thereof, which provides stable communication between the artery and the vein of the patient under hemodialysis and can greatly reduce stenosis at arteriovenous connections. As a base material of the hemodialysis tube, expanded polytetrafluoroethylene is used while the medicament is paclitaxel or rapamycin.
