Abstract: The present disclosure relates to an antibody binding specifically to CD55 or an antigen-binding fragment thereof; and a composition for preventing, treating and/or diagnosing cancer containing the same. The antibody of the present disclosure may be used as an effective therapeutic composition for various CD55-mediated diseases since it shows high binding ability and inhibitory effect for the CD55 protein which promotes tumor growth by inhibiting the complement immune mechanism. In addition, the antibody of the present disclosure may be usefully used as an effective therapeutic adjuvant that fundamentally removes drug resistance and remarkably improves therapeutic responsiveness in various diseases in which resistance to therapeutic agents with CDC (complement-dependent cytotoxicity) as a mechanism of action has been induced due to overexpression of CD55.

Abstract: Provided is a bioresorbable stent including a stent substrate including a bioresorbable polymer and a contrast medium containing an iodine component, coated on the stent substrate. Since the stent according to the present invention is absorbed in and removed from the human body after a predetermined time, it has excellent biodegradability since it has improved radiopacity by iodine contrast medium coating, it has a high radiography contrast and is very efficient even when a procedure is performed with real time radiography, and since it has low foreshortening and high flexibility, radial force, and re-coil, it may be useful for insertion into a blood vessel having a small diameter, an acute occlusive lesion, an imminent occlusive lesion, and the like.

Abstract: The present invention relates to an auxiliary precursor, a thin film precursor composition, a method of forming a thin film using the thin film precursor composition, and a semiconductor substrate fabricated using the method. The present invention provides the thin film precursor composition including a thin film precursor compound and a compound having a predetermined structure that exhibits reaction stability as the auxiliary precursor. By using the thin film precursor composition in a thin film deposition process, side reactions may be suppressed, and thin film growth rate may be appropriately controlled. In addition, since process by-products are removed from a thin film, even when a thin film is formed on a substrate having a complicated structure, step coverage and the thickness uniformity and resistivity characteristics of the thin film may be greatly improved.

Abstract: A method performed by a managing server includes: receiving, from an electronic device, operation data of the electronic device; identifying, by using artificial intelligence (AI), a device usage pattern of the electronic device; identifying, by using the AI, information related to a failure or an abnormal operation of the electronic device and a solution to the failure or the abnormal operation based on the device usage pattern and the operation data received from the electronic device; and transmitting, to a user terminal, the information related to the failure or the abnormal operation of the electronic device and the solution to the failure or the abnormal operation.

Abstract: The present disclosure relates to a serum exosomal SF3B4 marker composition for diagnosing early stage hepatocellular carcinoma for noninvasive in vitro diagnosis, wherein, by analyzing an expression level of SF3B4 in plasma proteins as well as expression of SF3B4 in exosomes present in sera of hepatocellular carcinoma patients, the possibility as the most suitable liquid biopsy marker was identified, and a new noninvasive biomarker with high diagnostic accuracy in early stage hepatocellular carcinoma for which no reliable biomarker exists at this present was discovered. As such, by using exosomes to identify cancer cell genomes and proteomes without biopsy, the exosomes are highly applicable in the future as a diagnostic biomarker that is useful in a disease group with a high risk in the biopsy such as hepatocellular carcinoma.

Abstract: The present invention relates to a method for designing a cycloidal gear tooth profile of a gear shift actuator, the method designing a profile to have a backlash through a change in the radius of a rolling circle of an internal or external tooth profile of a cycloidal gear, and thus enables the smooth engagement of internal teeth and external teeth, reduces the engagement range of the internal teeth and the external teeth to have excellent durability and enable power loss to be reduced, and enables the shape machining of the gear by using general cycloidal gear machining, thereby facilitating manufacturing and being capable of improving machining precision.
