Abstract: An aerosol-generating article according to one aspect of the present disclosure may include a tobacco medium portion, a filter portion disposed to be spaced apart from the tobacco medium portion, a wrapper surrounding the tobacco medium portion and the filter portion, and a cooling portion surrounded by the tobacco medium portion, the filter portion, and the wrapper so as to have a space therein.

Abstract: An aerosol-generating article according to one aspect of the present disclosure may include a tobacco medium portion and a filter portion coupled to a side of the tobacco medium portion and cooling and filtering an aerosol delivered from the tobacco medium portion. The filter portion may include a first filter segment disposed to be spaced apart from the tobacco medium portion and filtering the aerosol, an inner wrapper surrounding the first filter segment and extending toward the tobacco medium portion, and a second filter segment surrounded by the tobacco medium portion, the first filter segment, and the inner wrapper so as to have a space therein.

Abstract: A cylindrical secondary battery and a manufacturing method of a secondary battery are provided. A manufacturing method of a cylindrical secondary battery includes: winding an electrode assembly to expose a first electrode uncoated portion and a second electrode uncoated portion to opposite ends in a longitudinal direction; bending at least some portions of the first electrode uncoated portion and the second electrode uncoated portion of the electrode assembly in a direction by pressing the first electrode uncoated portion and the second electrode uncoated portion; welding electrode collector plates to ends of the bent first and second electrode uncoated portions; and inserting and sealing the electrode assembly into a cylindrical case.

Abstract: Provided is a duct docking device for a ventilation seat of a vehicle. The duct docking device enables air to be easily blown to a seatback and a seat cushion with a passenger in a seat using only one blower by enabling a seatback duct mounted at the seatback and a seat cushion duct mounted at the seat cushion to be hermetically docked through a connector duct, etc. at an unfolded position of the seatback in which a passenger can sit, and by enabling the seatback duct mounted at the seatback and the seat cushion duct mounted at the seat cushion to be separated from each other at a folded position of the seatback in consideration of that there is no passenger in the seat.

Abstract: The present invention provides a compound having an effect of preventing and/or treating the damage or degeneration of cochlear (and vestibular) mother cells and spiral ganglion neurons by downregulating a cysteinyl leukotriene receptor. Particularly, the present invention provides a composition for preventing or treating sensorineural hearing loss, containing a cysteinyl leukotriene receptor and a Ginkgo biloba extract as active ingredients, on the basis of the co-administration of a cysteinyl leukotriene receptor and a Ginkgo biloba extract having an excellent effect of protecting hearing.
