Abstract: An intake air guide device for a vehicle includes an air guide surrounding the outside of a heat exchanger mounted on a front portion of a vehicle and extending forward to guide an airflow so that the air flowing into the front portion of the vehicle flows into the heat exchanger, and a sealing guide extending backward from the front portion of the vehicle to surround the air guide in a state of being spaced apart from the outside, and extending inward or outward to overlap the air guide.

Abstract: An embodiment core molding system includes an upper hopper partitioned to define a first accommodating part that accommodates first core sand coated with an organic binder and a second accommodating part that accommodates pure sand, a lower hopper disposed under the upper hopper and connected to the first and second accommodating parts, the lower hopper being configured to measure weights of the first core sand and the pure sand, a mixer connected to the lower hopper, wherein the mixer is configured to allow the first core sand to pass directly therethrough and to accommodate the pure sand, a binder supply unit connected to the mixer and configured to supply an inorganic binder into the mixer, and a core mold configured to mold each of the first core sand and second core sand into a preset shape, the second core sand including the pure sand coated with the inorganic binder.

Abstract: The invention relates to a method and a system for improving performance of text summarization and has an object of improving performance of a technique for generating a summary from a given paragraph. According to the invention to achieve the object, a method for improving performance of text summarization includes: calculating a first likelihood of each of a plurality of nodes included in a graph corresponding to a natural language-based context; calculating a second likelihood of each of the plurality of nodes by assigning a weight to a first likelihood of a node corresponding to a keyword not presenting in the context among a plurality of keywords corresponding to each of the plurality of nodes; calculating a third likelihood of each of all paths present in the graph based on the second likelihood of each of the plurality of nodes; and generating a summary for the context based on a path having the highest third likelihood among the paths.

Abstract: A grinding wheel includes a plurality of wheel tips. The plurality of wheel tips include a plurality of diamond abrasive grains and a bonding material mixed with the diamond abrasive grains. The plurality of diamond abrasive grains have a ratio of a length in a long axis direction to a width in a short axis direction of 1:2.5 to 1:3.5 and includes edges or vertices having a grinding angle of 90° or less.
