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: A bypass apparatus of an oil cooler is provided that includes an oil pump that is configured to supply oil in an oil pan to an engine through an oil cooler and an oil filter. In addition, a solenoid valve is connected to front and rear ends of the oil cooler and is configured to change a circulation path of oil by being opened or closed by a controller.

Abstract: A method for diagnosing a bypass valve on an oil cooling circuit for vehicles includes: a measurement step of measuring a temperature of a downstream oil of the bypass valve, a prediction step, and a diagnosis step. The prediction step compares the temperature of the downstream oil with an opening reference temperature or a closing reference temperature and predicts an open or closed state of the bypass valve. The diagnosis step depending on a result of the prediction step, compares the temperature of the downstream oil with a lowest reference temperature or a highest reference temperature and diagnoses whether the bypass valve is in a failure state in which the bypass valve is stuck in an open or closed state.
