Abstract: The present invention relates to a method of simultaneously diagnosing active tuberculosis and latent tuberculosis infection (LTBI) using one or more biomarkers selected from a white blood cell count, a hemoglobin concentration, a neutrophil count, a lymphocyte count, a monocyte count, a procalcitonin concentration, a C-reactive protein concentration, an ?1-acid glycoprotein concentration and an erythrocyte sedimentation rate, or a combination thereof. The present invention may provide a diagnostic method for simultaneously differentiating active tuberculosis and LTBI without a separate additional test on a patient diagnosed as positive by a conventional tuberculosis infection assay such as a tuberculin skin test (TST) or an interferon-? release assay (IGRA).

Abstract: A system, apparatus, and method for generating one or more path rules or combination or path rules for performing the operations of an application. According to various embodiments, a user terminal through an intelligence server may generate a path rule and may perform the operation of an application based on the path rule to provide a service. The user terminal may provide a user with the processing status of a user utterance and may receive an additional user input to process the user utterance. For example, when a keyword (or parameter) required to process the user utterance is insufficient, the user terminal may provide the user with a state requiring additional information and may output feedback corresponding to the insufficient state in order to receive the necessary information from the user.

Abstract: An engine device for a vehicle is configured such that a clutch pulley may be rotated together with a crankshaft or may not be rotated depending on the application of electric power. Therefore, when an auxiliary drive system does not need to rotate, the clutch pulley is prevented from rotating. Accordingly, torque loss attributable to dispersion of torque to the auxiliary drive system is minimized As a result, fuel efficiency is improved, and engine output is increased.
