Abstract: A light emitting module unit includes a circuit board and a light emitting device. The light emitting device includes a plurality of light emitting elements electrically coupled through the circuit board, one or more electrodes arranged on a first surface of the plurality of light emitting elements, a surface barrier formed on a second surface of one or more of the plurality of light emitting elements, and an encapsulation portion disposed above a third surface of the plurality of light emitting elements. The surface barrier is disposed between the encapsulation portion and the second surface of one or more of the plurality of light emitting elements.

Abstract: A display device and a method of driving a display device are disclosed.

Abstract: A catheter-type ultrasound endoscope according to an embodiment of the present invention includes an ultrasound module for acquiring an ultrasound image, and a biopsy needle, wherein the ultrasound module includes a pMUT module and an ASIC signal processing circuit, and the ASIC signal processing circuit uses CMOS-MEMS technology. This steerable catheter-type ultrasound endoscope capable of performing tissue biopsies according to the present invention obtains ultrasound images from representative digestive organs, such as the bile duct and the pancreatic duct, through the miniaturization of the ultrasound module, and performs a biopsy while the ultrasound images are observed in real time, and thus can improve the accuracy of diagnosis.

Abstract: The present invention provides a capsule for diagnosis of Helicobacter pylori including a body section into which a gastrointestinal fluid including the Helicobacter pylori is selectively introduced; a decomposition section that is accommodated in the body section and contains urea; a sensor unit for measuring information on a result of decomposing the urea by Helicobacter pylori in the decomposition section; and a control unit for transmitting the information measured by the sensor unit to the outside.

Abstract: Disclosed is a therapeutic patch for the gastrointestinal tract including a mucoadhesive material along with magnetic nanoparticles and a drug to be delivered to a living body, which are supported on the mucoadhesive material. A method of manufacturing the therapeutic patch for the gastrointestinal tract is also provided and includes preparing a mucoadhesive polymer, preparing a catechol precursor, mixing the mucoadhesive polymer and the catechol precursor, freeze-drying a mixture in the mixing step, mixing a powder resulting from the freeze-drying step with magnetic nanoparticles and a drug, and subjecting the resultant mixture to molding using a mold and then freeze-drying.

Abstract: A biopsy needle device for collecting a tissue sample by penetrating a living body includes a needle. The needle includes a tip portion having a cross-sectional area getting gradually smaller toward a front end thereof and a tissue container portion arranged behind the tip portion for holding the tissue sample therein. The tip portion includes a rear surface contiguous to the tissue container portion and a recess formed on the rear surface.
