Abstract: Disclosed herein are a microorganism with excellent deacetoxycephalosporin C (DAOC) productivity and a use thereof. A mutant microorganism with improved DAOC productivity and a use thereof for producing 7-aminodeacetoxycephalosporanic acid (7-ADCA) are provided.

Abstract: A switch apparatus, includes: a base module including a base case, and a moving magnet movably mounted in the base case; and a manipulation module including a manipulation case, and a first magnet fixedly mounted in the manipulation case, wherein the moving magnet moves between a hold position and a releasable position, the hold position refers to a position in which the manipulation module is held onto the base module as an attractive force acts between the moving magnet and the first magnet, and the releasable position refers to a position in which the manipulation module is releasable from the base module as a repulsive force acts between the moving magnet and the first magnet.

Abstract: A spiral phase plate, according to one embodiment, for generating a Laguerre Gaussian beam by reflecting an incident beam emitted from a light source, may comprise: a first quadrant area in which the step height increase rate per unit angle decreases progressively in one direction from the point with the lowest step height to the point with the highest step height; and a second quadrant area in which the step height increase rate per unit angle increases progressively in the one direction.

Abstract: Disclosed are novel compounds of Chemical Formula 1, optical isomers of the compounds, and pharmaceutically acceptable salts of the compounds or the optical isomers. The compounds, isomers, and salts exhibit excellent activity as GLP-1 receptor agonists. In particular, they, as GLP-1 receptor agonists, exhibit excellent glucose tolerance, thus having a great potential to be used as therapeutic agents for metabolic diseases. Moreover, they exhibit excellent pharmacological safety for cardiovascular systems.

Abstract: The present disclosure relates to a multipurpose laser pointing-equipment for medical use, and more particularly to a multipurpose laser pointing-equipment for medical use that can minimize errors in an operation (treatment, surgery) by definitely marking a reference for a surgery part from the outside the patient's body using point and line types of laser beams and by making it possible to accurately measure the surgical target. The present disclosure is characterized by including: a pointer assembly lifted from a floor and emitting downward a laser beam for marking a reference for a surgical part on the body of a patient and for measuring a surgical range; a standing base being a basis for supporting the equipment in an erect position; a positioning supporter being erect on the standing base to lift the pointer assembly and adjust a height, a position, and an angle of the pointer assembly; and a controller disposed at a position for a user to operate the equipment.

Abstract: Disclosed herein is a complex spine-inspection support apparatus capable of multi-posture correction, which can apply various acting forces in a longitudinal direction of a spine while stably maintaining a patient's posture, can transmit a constant bending force to the left and right, thus facilitating accurate and various inspections, and can observe a spinal disc ligament varying depending on a posture.

Abstract: Novel tools and techniques are described for generating or extracting keywords based on trend data related to contemporary news events, social media topics, and/or Internet searches, etc. Local and/or remote content catalogs, which are respectively associated with local and remote content libraries, are searched for relevant multimedia content (e.g., video, audio, and/or written content) using the generated or extracted keywords. Dynamic automated on-demand and/or broadcast channels are generated that incorporate the relevant multimedia content, and streamed and/or broadcast to one or more user devices (including PCs, televisions, and mobile devices). User-interactive selection capabilities are optionally provided during the channel generation process.
