Abstract: Disclosed are a lead frame and a method for manufacturing the same. The lead frame includes a copper substrate and a rough copper layer having surface roughness of 110 nm to 300 nm on a surface of the copper substrate.

Abstract: An expanding vascular stent is disclosed that is inserted into a blood vessel in the human body and expands the blood vessel. The stent is configured in such a way that adjacent rows, each of which is comprised of a plurality of identical cells, are symmetrically arranged, in an out of phase manner. When the stent is expanded in the radial direction, the adjacent rows are expanded in opposite directions, maintaining their linearly symmetrical state. Therefore, the reduction in the length of the stent can be minimized. Since the stent has also a great degree of flexibility, when it is inserted into the blood vessel, it can minimize the damage to the blood vessel wall.

Abstract: Disclosed herein is a method for enhancing sensitivity of cancer cells to compounds or radiation by inhibiting the expression of testis-specific protein, Y-encoded like 5 (TSPYL5). More specifically, because methylation of TSPYL5 protein expressed in lung cancer cell line was inhibited to increase the expression level of the gene, resistance to stress such as radiation or anticancer agents was increased. Because the sensitivity of cancer cells to stress such as radiation or anticancer agents was increased by inhibiting the expression of the TSPYL5 gene to promote the apoptosis of the cells, an anticancer supplement agent containing an inhibitor of the expression or activity of the TSPYL5 gene of the present invention inhibits the growth of cancer cells and enhances the sensitivity to various stresses to maximize the apoptosis. Thus, when used in combination with radiotherapy or chemotherapy, the anticancer supplement agent may be used very usefully for anticancer treatment.

Abstract: A color correction apparatus and method thereof in an image system are capable of automatically processing color correction by storing reference colorimetric data regarding a predetermined test pattern for estimating the color correction in a storage medium, and then scanning the estimating test pattern so that the color correction can be performed by minimizing an error between the reference data and the scanning data obtained by scanning the test pattern. As a result, color correction can be performed without using an optical densitometer or a colorimeter, and the operation for correcting the color can be performed without knowledge of the color coordinate system or the color signal.

Abstract: A sensor-to-sensor distance correcting method and a circuit therefor in an image reading apparatus having a plurality of line sensors are provided.

Abstract: An image scanning apparatus which can reduce a shading distortion generated by luminous characteristics of a light source, vignetting of a lens, etc. adopts color filters having a geometrical structure which enables to counterbalance a shading distortion and is characterized in that a line sensor is vertically arranged for the radial direction of the rotary filter. The image scanning apparatus can accomplish a simple shading calibration by arranging color filters and the line sensor so that a shading distortion is calibrated geometrically.

Abstract: An apparatus for converting a resolution and a gray scale of document image data, which includes a latch circuit for setting variable values of image control data, a resolution-converting clock generator for generating resolution-converting clock signals, a clock selector for selecting a pixel clock signal, a unit data detector for detecting byte detecting clock signal according to gray scale conversion as a unit data, an image data converter for gray scale conversion and binary codification of the image data, an image data selector for selecting the gray scale of the image data of the image data converter, and an image data output portion for outputting the image data with the selected gray scale in units of bytes. The image data processing can be performed at high speed, and the resolution and the gray scale control is carried out in the hardware, which allows the apparatus to be highly compatible and also to be widely adapted.
