Abstract: Disclosed is a target-based drug screening method using inverse quantitative structure-(drug)performance relationships (QSPR) analysis and molecular dynamics simulation. The method includes modeling a molecular structure of a test compound group against a target molecule, obtaining a quantitative structure-(drug)performance relationships (QSPR) of the test compound group, acquiring the optimal pharmacophore of a novel target-based drug through a numerical inversion of the QSPR, and selecting drug candidates having a molecular structure similar to the optimum pharmacophore from the test compound group.

Abstract: Disclosed are a method of manufacturing a billet used in plastic working for producing a composite member and a billet manufactured by the method. The method includes (A) ball-milling powders of two more materials to prepare a composite powder and (B) preparing a multi-layered billet containing the composite powder. The multi-layered billet includes a core layer and two or more shell layers. The shell layers except for the outermost shell layer are made of the composite powder. The outermost shell layer is made of a pure metal or metal alloy. The composite powders contained in the core layer and each of the shell layers have different compositions. The method has an advantage of manufacturing a plastic working billet being capable of overcoming the limitation of a single-material billet and enabling production of a characteristic-specific composite member such as a clad member.

Abstract: The present invention relates to: a portable probe for photoacoustic tomography, capable of performing line-by-line scanning or area-by-area scanning by using a small number of light inputs; and a real-time photoacoustic tomography device. The probe for photoacoustic tomography includes: a lens receiving light inputs from an optical fiber so as to make the same proceed as small diameter parallel light; a Powell lens receiving the small diameter parallel light and generating a line beam of a predetermined thickness, and allowing energy dispersed on a line to be uniform on the entire line; a lens making the line beam pass therethrough such that the line beam has a predetermined width and a reduced thickness so as to be line-focused at a target area; an acoustic reflection glass for separating, from a light path, an acoustic wave outputted from the target area; and an acoustic measurement unit for measuring acoustic strength.
