Abstract: In a display apparatus, a projected member is arranged in a direction in which a driver of a moving body looks while driving, from the perspective of the driver. A projecting unit projects at least one display object in a position that overlaps a background that is visible to the driver through the projected member, so as to be displayed in a superimposed manner as a virtual image. A measuring unit measures a luminance value of the background. A control unit determines a luminance value of the display object based on the luminance value of the background measured by the measuring unit, chromaticity values of the display object, and a sense of superimposition that is a value having a range of 0 or greater and 100 or less, and controls the projecting unit such that the display object is projected at the luminance value of the display object.

Abstract: The present invention is produced as a polymerized peptide prepared by oxidatively cross-linking collagen-like peptides having the triple-helical structure containing three peptide chains each containing multiple cysteine (Cys) residues. This polymerized peptide can be processed into a hydrogel and a thin membrane sheet before use, and is capable of imparting a particular physiological function such as cellular adhesion by incorporating functional amino acid sequences present on biological polymers. Further, the present invention provides a method for producing the abovementioned polymerized peptide and the like; and use applications employing the same, such as cell culturing, wound dressing, and compositions including regenerative medical materials and research materials.

Abstract: An analysis method and a diagnostic device, enabling one to determine whether a longitudinal melanonychia is caused by a malignant melanoma or a benign nevus by correcting color variation in a dermoscopic image through standardization of color balance without depending on an imaging device or an operator; and a computer program for allowing a computer to function as the diagnostic device. Proposed is a structure including: an image reading step of reading a color image of a longitudinal melanonychia or an affected skin site of a subject as a digital color image; an image processing step involving an image size conversion step of converting the whole size of the digital color image into a preset size through pixel size conversion, and a region of interest (ROI)-extraction step of extracting an ROI required for the diagnosis from the digital color image; a chromatic adaptation transformation step of controlling the color balance of the digital color image data through chromatic adaptation transformation; and a discrimination index (DI) calculation step of determining a DI value using the image after the chromatic adaptation transformation.
