Abstract: The presents invention relates to a composition for manipulating an immune cell which is used for artificially manipulating an immune cell. More particularly, the present invention relates to a composition for manipulating an immune cell which is used for artificially manipulating an immune cell and a manipulated immune cell comprising an artificially modified immunity regulating gene and an artificial receptor which is produced using the composition, and use thereof.

Abstract: An exemplary embodiment provides matching media for perfect transmission of ultrasonic waves by easily implementing perfect transmission of ultrasonic waves at a boundary between different elastic media through a matching layer provided at the boundary between the different elastic media and proposes a matching layer having a single layer structure of a simple single pattern that is easily processed, thereby easily implementing effects such as miniaturization of the matching layer, reduction of manufacturing cost, and improvement of manufacturability.

Abstract: An exemplary embodiment attempts to provide a full transmission device for wide-angle mode conversion of elastic waves which can realize mode conversion of elastic waves with high energy efficiency over a wide range of angle of incidence by a single filter. A full transmission device for wide-angle mode conversion of elastic waves includes an incidence medium where elastic waves including longitudinal waves and transverse waves enter obliquely within a preset wide angle range, a transmission medium that transmits elastic waves when the elastic waves enter the transmission medium within the wide angle range through the incidence medium, and a filter that is formed so as to satisfy a wide-angle mode conversion full-transmission condition when the filter is interposed between the incidence medium and the transmission medium, such that elastic waves entering the incidence medium within the wide angle range are completely converted without being reflected so as to be transmitted to the transmission medium.

Abstract: Disclosed is an acoustic matching member comprising matching pattern to determine an impedance of the acoustic matching member and a phase change of the acoustic matching member defined as the product of a wave number and thickness of the acoustic matching member, which satisfies the impedance and the phase change matching conditions so that 90% or more of an ultrasound may be transmitted through a barrier located between an incident medium and a target medium.

Abstract: A thin film thickness measuring apparatus and a method that can overcome the measurement limit of the reflected ultrasonic wave signal when measuring the thickness of a thin film using retroreflection of ultrasonic waves can be provided. A thin film thickness measuring apparatus includes: an ultrasonic retroreflector that is provided under a test object formed in the shape of a thin film and retroreflects an ultrasonic wave incident through the test object; an ultrasonic wave input portion that is provided on one side of the test object and inputting an ultrasonic wave to one side of the test subject; and a measurement portion that is connected to the ultrasonic wave input portion and measures an arrival time of the ultrasonic wave reflected through the test object.
