Abstract: The disclosure relates to a tobacco material including a flavor material and a method of preparing the tobacco material. The tobacco material may have a core-shell structure in which a core includes a first tobacco mixture and a flavor material and is surrounded by a shell including a second tobacco mixture, such that the aerosol generating article including the tobacco material generates a characteristic flavor.

Abstract: The present invention relates to a method for determining the DNA quality of a biological sample and, more specifically, to a method for determining the DNA quality of a biological sample by performing a quantitative polymerase chain reaction (PCR) using primers capable of amplifying a target gene, a method for preparing the primers used in the method, and a method for standardizing the amount of detected target gene mutation by using the determined DNA quality. The method of the present invention enables objective evaluation of the DNA quality of a biological sample used in gene analysis and the presentation of objective results on the expression ratio of a gene mutation, thereby providing reliable information in the fields of clinical research and companion diagnosis.

Abstract: An embodiment of the present disclosure discloses tobacco material including: a center portion including a flavor material; and an outer portion including a tobacco mixture, wherein the outer portion surrounds the center portion.

Abstract: Proposed is a terminal coupling structure of an electric actuator in which a press rib is installed on the end of a contact plate such that a contact protrusion and a motor assembly terminal are more securely in contact with each other.

Abstract: A flexible vibration module is disclosed. The flexible vibration module includes a piezoelectric composite layer, including: a plurality of piezoelectric portions each having a piezoelectric characteristic, where at least two of the plurality of piezoelectric portions have different sizes; and a flexible portion between the plurality of piezoelectric portions.

Abstract: Proposed is a terminal coupling structure of an electric actuator in which a press rib is installed on the end of a contact plate such that a contact protrusion and a motor assembly terminal are more securely in contact with each other.

Abstract: A sweatband using micro fiber yarn for headwear that is made to 0.5˜1.05 denier thickness of micro fiber yarn and woven of 100% polyester warp-way and weft-way, made to single or two-ply without any polyurethane and additional stitched portion. The resulting sweatband, which preferably provides excellent sweat absorbing capability, and having high dryness factor, anti-static electricity function and the highly washable function, and exhibits good elasticity through the structure of the textile without imposing undue pressure on the wearer, with the result that the sweatband may be worn comfortably for long periods of time. The yarn used to produce the sweatband is processed by high temperature and piece dyeing methods and has twist per each certain length.
