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 cooling portion disposed between the tobacco medium portion and the filter portion, and a heat transfer portion surrounding at least a portion of the cooling portion.

Abstract: An aerosol generating device includes an accommodation space in a cylindrical shape for accommodating a cigarette, an induction coil wound along an outer surface of the accommodation space, a power supply for supplying electric power to the induction coil, a controller for controlling electric power supplied to the induction coil, and a shield film including a ferromagnetic material for shielding electromagnetic interference from electromagnetic waves emitted from the induction coil. The shield film surrounds only a portion of an outer surface of the induction coil to shield the electromagnetic interference from the electromagnetic waves having a frequency that does not exceed 500 kHz.

Abstract: Provided is an apparatus for generating an aerosol by induction heating, the apparatus including: at least one susceptor formed in an elongated structure extending in a longitudinal direction of a cigarette to be accommodated in the apparatus, and arranged to be inserted into the cigarette to heat the cigarette; an ejector including an accommodating space for accommodating the cigarette, and an opening formed at one end of the accommodating space so that the cigarette is inserted in the accommodating space, wherein the at least one susceptor is arranged opposite the one end in the accommodating space, and the ejector is detached from and attached to the apparatus together with the at least one susceptor; and a coil arranged to surround the ejector along the longitudinal direction when the ejector is coupled to the apparatus, and configured to apply an alternating magnetic field to the at least one susceptor so that the at least one susceptor generates heat.

Abstract: According to an example, artificial ovulation and spawning of freshwater eels may be induced to promote artificial ovulation without employing intraperitoneal injection, by feeding a feminization-inducing material (e.g., 17?-estradiol) for inducing feminization during a predetermined period into a raising bath in which broodfish are raised and, when an ovulation induction period arrives, adding pituitary extracts of catadromous fish as an artificial ovulation-promoting substance to the bath. Raising water of the raising bath may be prepared by selectively setting fresh water, brackish water and seawater conditions, a feminization-inducing material for inducing complete feminization of broodfish of the freshwater eels is fed to the raising bath, including the raising water under a fresh water condition, and pre-treatment for feminization is performed.
