Abstract: A developed impact mark analysis apparatus includes: an image acquisition unit configured to obtain at least one first image by photographing impact marks that are developed, and to obtain a second image of impact marks at a crime scene that are developed from evidence at the crime scene; an outliner configured to outline the at least one first image to obtain at least one first outline image, and to outline the second image to obtain a second outline image; a database configured to store the first outline image corresponding to related tool characteristic information; a matching unit configured to search the database for the first outline image determined to be similar to the second outline image and match them with each other; a display unit; and a user input unit.

Abstract: A semiconductor device includes: a substrate includes an active area; a first landing pad connected to the active area and disposed on the substrate; a second landing pad connected to the active area, and spaced apart from the first landing pad, wherein the second landing pad is disposed on the substrate; a first lower electrode disposed on the first landing pad and extending in a direction substantially perpendicular to the substrate; a second lower electrode disposed on the second landing pad and extending in the direction substantially perpendicular to the substrate; a dielectric layer extending along the first lower electrode and the second lower electrode; and an upper electrode disposed on the dielectric layer, wherein a first upper surface of the first landing pad is disposed below a second upper surface of the second landing pad with respect to a lower surface of the substrate.

Abstract: A road guide post includes: a supporter which is fixed to the ground by being coupled to an anchor bolt; a guide post body which has a post shape that is screw-coupled to or fitted into the supporter; reflective sheets, multiple layers of which are attached to the concave groove part of the guide post body; and a bracket which is inserted and fixed into the bottom surface of the supporter.

Abstract: The present invention relates to a road guide post comprising: a supporter (110) which is fixed to the ground by being coupled to an anchor bolt (10), and which is provided in the form of a semicircular body; a guide post body (120) which has a post shape that is screw-coupled to or fitted into the supporter (110), with a concave groove part (111) on the upper outer surface of the body to allow reflective sheets to be attached thereto; reflective sheets (130), multiple layers of which are attached to the concave groove part (111) of the guide post body (120): and a bracket (140) which is inserted and fixed into the bottom surface of the supporter (110) and is used to reinforce the coupling force of the anchor bolt (10).

Abstract: Disclosed herein is an end-cap structure of an oil filter for vehicles. The end-cap includes a base cap which has a hole in a central portion thereof, and a hook cap which is installed in the hole so as to be movable upwards or downwards. In this structure, a surface of the hook cap that comes into contact with the base cap when the hook cap moves upwards is a sealing portion. When the hook cap moves downwards, the sealing state is released and a bypass is formed. According to the structure of the present invention, since the sealing portion of the end-cap can be protected from heat, the quality of the product, the productivity, the economic efficiency, etc. can be enhanced.

Abstract: The invention relates to a method for manufacturing dielectric ceramic powder and a multilayer ceramic capacitor using the ceramic powder. According to the invention, BaCO3 powder is dispersed into a solution of solvent and dispersant to prepare BaCO3 slurry and then the resultant BaCO3 slurry is wet-milled. Also, TiO2 powder slurry is mixed into the wet-milled BaCO3 slurry to form mixed slurry and then the mixed slurry is dried into mixed powder. Finally, the dried mixed powder is calcined to produce BaTiO3 powder.
