Abstract: A light generating unit includes a plurality of light sources generating lights with different wavelengths. Among the light sources, at least one is disposed on a horizontal surface which differs in height from horizontal surfaces on which the other light sources are disposed. A display device includes the above light generating unit and a display panel for displaying an image by using the lights generated from the light generating unit. A method of improving color uniformity in the display device includes arranging the light sources as in the light generating unit.

Abstract: Provided is a method for identifying relevant groups of genes using gene expression profiles. More particularly, it is provided a method for identifying relevant groups of genes using gene expression profiles, which analyzes the gene expression profiles obtained from microarray experiments to automatically extract seed genes of significance and identifies the relevant groups of genes based on the extracted seed genes, so that effective identification is possible regardless of the number of genes and a blind setting of initial input parameters are not required for users to readily use the method, wherein the method comprises the steps of (a) preprocessing the gene expression profiles; (b) setting the number of gene groups to be desired (k) and a input parameter(s); (c) extracting k seed genes (k=1, 2, 3, . . . ,n) based on the set input parameter(s); (d) identifying relevant groups of genes by means of the extracted seed genes; and (e) evaluating the identified relevant groups of genes.

Abstract: A method for manufacturing a planar optical waveguide, includes the steps of coating, over a lower cladding layer, an optical waveguide layer including an inorganic-organic matrix uniformly doped with photosensitive photochemical monomers, selectively exposing the waveguide layer to a beam with a predetermined range of wavelengths so as to immobilize the doped photochemical monomers, and thermally treating the waveguide layer to remove unexposed monomers and cure the exposed optical waveguide layer. Requiring no etching processes, the method can reduce the number of processing steps and produce a planar optical waveguide with a low optical loss.
