Abstract: A defect detection system for detecting a defect of an aircraft component object includes an image processing unit configured to extract, from an original image of the object including a defect point, a defect candidate region based on luminance of the image, and calculate a feature amount of the defect candidate region based on a difference in luminance between the defect candidate region and surrounding regions; a setting unit configured to associate the feature amount for an original image for learning with information about the defect point to set a defect feature amount range or a non-defect feature amount range; and a defect detection unit configured to determine, based on the feature amount for a target original image in which a defect point is not detected yet, the defect and non-defect feature amount ranges, whether the defect candidate region in the target original image is a defect point.

Abstract: The present invention provides a ceramidase activity inhibitor which inhibits ceramidase activity, specifically neutral/alkaline ceramidase activity, characterized in that the inhibitor comprises, as an active ingredient, a processed product derived from at least one plant selected from the group consisting of plants belonging to Ginkgoaceae, plants belonging to Cucurbitaceae, plants belonging to Rutaceae, plants belonging to Laminariaceae, plants belonging to Myrtaceae and plants belonging to Compositae, and a medicament, a quasi-drug, cosmetics and a food, each comprising the inhibitor.
