A silicon crystallization method renders it is possible to form alignment key without additional photolithography, and to adjust a substrate to a correct position by sensing a deviation of the substrate when the substrate is loaded. The silicon crystallization method includes aligning the substrate by sensing a fixed substrate with a sensing device, and moving and/or rotating a stage, wherein the sensing device faces toward an edge of the substrate to directly sense the edge of the substrate; forming alignment keys on predetermined portions of a non-display area of the substrate by correspondingly placing a mask for formation of an alignment key above the substrate; and crystallizing an amorphous silicon by correspondingly providing a mask for crystallization above the substrate.

The present invention relates to the elucidation of a gene that can act as a novel marker for liver cancer diagnosis and to diagnostic and prognostic measurements of liver cancer using the same. More specifically, it relates to a diagnosis kit that enables diagnostic and prognostic measurement of a liver cancer using a preparation that measures expression levels of at least one gene selected from a group of liver cancer diagnosis markers consisting of S100P, NK4, CCL20, CSPG2, PLAU, MMP12, ESM-1, ABHD7, HCAPG, CXCL-3, Col5A2, MAGEA, GSN, CDC2, CST1, MELK, ATAD2, FAP and MSN and/or a method for diagnostic and prognostic measurement of liver cancer using the same. These have been discovered using normal liver tissues and liver cancer tissues collected from the same liver cancer patient of the present invention and represent the markers whose accuracy and reliability have been greatly improved as markers of liver cancer. The markers of the present invention can be used for the accurate diagnosis and prognosis of liver cancer.
