Abstract:
The present invention relates to a biopolymer-modified nanocarrier in which chitosan is bound to a water-soluble biocompatible polymer that has been crosslinked via a photo-crosslinkable functional group; wherein the chitosan-modified nanocarrier has a diameter which changes in accordance with changes in temperature, has enhanced skin permeability or cellular uptake and selective delivery to cancer tissue as compared with a bare nanocarrier to which chitosan has not been bound, and exhibits characteristics that are advantageous in photothermal therapy. The chitosan-modified nanocarrier of the present invention exhibits highly superior efficacy as a transdermal carrier, since the skin permeability is enhanced to a very suppressing level as compared with a bare nanocarrier that has no chitosan. The chitosan-modified nanocarrier of the present invention can be used to very great advantage in the imaging and photothermal therapy of tumour cells and cancer cells, since the cellular uptake by tumour cells and cancer cells is substantially improved.

Abstract:
A mobile terminal and an interface method thereof for connecting external devices, such as an adapter, a Universal Serial Bus (USB) cable, a docking station, an accessory, and the like, to the mobile terminal are provided. The mobile terminal includes a battery, a connector including a pin for data communication and first and second power pins for charging the battery, a memory for storing a reference voltage indicating a dedicated adapter of the battery, and a controller for receiving a voltage input from the first and second power pins, for recognizing an external device connected with the connector as the dedicated adapter when a voltage input from the pin for data communication is the reference voltage, and for charging the battery with power input to the first and second power pins.
Abstract:
Disclosed are a nanoparticle having a size of 1-20nm prepared by electrolyzing a tin or a tin alloy, and a method for preparing same. The nanoparticle surface-melts in a temperature range of 80-130?. A solder ball having the nanoparticle can be sintered at or below 160?, and can thus, first, save 22% of energy by resolving the energy consumption of 74 kW for the conventionally used reflow processing device to an energy consumption of 50 kW by enabling the heating temperature to be lowered from 240? to 160? during reflow process. Second, deformation of a PCB board can be minimized by enabling the temperature for the reflow process to be lowered, and application areas for implementation materials having a low unit cost can be created by enabling the use of low cost polymer materials such as PET having low glass transition temperature. And third, the uniformity of a solder paste on a pad can be enhance when using a nanoparticle having a size of 10 nm or smaller, and in the case of a nano-solder ink, the limitations of micro-patterning can be overcome due to the small size of the particle (Figure 4).

Abstract:
An amplifier and an amplifying method are provided. The amplifier includes: an amplifying unit amplifying and transferring a transmission target signal to a TDD switch; the TDD switch transferring a signal received from the amplifying unit to a filter unit when the amplifier operates in a TDD mode, and transferring a signal received from the filter unit to a duplex mode selection switch; the duplex mode selection switch transferring a signal received from the filter unit to a receiving side; and a controller controlling the duplex mode selection switch to transfer the signal received from the filter unit to the receiving side without passing through the TDD switch when the received duplex mode selection signal is a FDD mode selection signal.
Abstract:
The present invention relates to a method for separating calgranulin A and ß-actin as dementia markers which can be utilized in the diagnosis and treatment of dementia, and to a composition for the treatment and identification of dementia (Alzheimer's disease, vascular dementia, alcoholic dementia), comprising an antibody that specifically binds to the calgranulin A and to â-actin. The separation method of the present invention comprises the following steps: separating blood cells containing leucocytes (neutrophils, monocytes, macrophages, granulocytes, etc.), erythrocytes, platelets, and the like from blood; performing DEAE-cellulose column chromatography on the blood cells; precipitating the blood cells using 30 to 80% of ammonium sulfate; performing ubiquitin-Sepharose affinity column chromatography on the blood cells; performing electrophoresis on the blood cells; and checking the proteins of the blood cells.

Abstract:
A matrix relay switch structure that is suitable for micro miniaturization is provided. A matrix switch for electrical signal connection between at least one signal input terminal and at least one signal output terminal is composed of electrical switches, each electrical switch including a signal connection unit opening and closing an electrical connection between a signal input terminal and a signal output terminal corresponding to each other, a first movable driver connected to the signal connection unit and driving the signal connection unit forward or backward, a forward/backward driving unit driving the first movable driver forward or backward and changing an electrical connection state made by the signal connection unit between the signal input terminal and the signal output terminal, and a bistable spring unit connected to the first movable driver and maintaining the electrical connection state while a stability state changes due to the first movable driver. Accordingly, a micro matrix relay switch that is micro miniature yet has excellent stability and expandability can be constituted.
