Abstract: Disclosed in the present specification is a liquid lipid composite composition comprising ceramide, cholesterol, a C10-30 unsaturated fatty acid having three or fewer double bonds, and natural oil or wax containing a C10-60 fatty acid ester or C10-60 fatty acid ester at a weight ratio of 1:0.03-3:2.5-12:0.3-6. The liquid lipid composite composition comprises a high content of ceramide and is present in a liquid state during storage at normal temperature, and thus can be easily applied as a formulation of a hair cosmetic composition. The liquid lipid composite composition, when used to treat hair, has excellent hair condition improving effects, such as improving the softness of the hair, enhancing the elasticity and strength of the hair, and increasing the shininess of the hair.

Abstract: A transmitter, such as a base station, identifies a potential collision between a first set of resources configured for a CORESET for a receiver and a second set of resources configured for a PT-RS for the receiver. The apparatus may determine whether colliding resources in the CORESET are configured/used for a control transmission or a data transmission. The apparatus punctures the PT-RS based on whether the colliding resources in the CORESET are configured/used for the control transmission (e.g., PDCCH). For example, the apparatus may puncture the PT-RS only for resource blocks of the CORESET colliding with the control transmission without puncturing the PT-RS over an entire set of the colliding resources configured for the CORESET. A receiver may similarly identify potential collisions and determine whether PT-RS will be punctured based on whether the colliding resources in the CORESET are configured/used for a control transmission or a data transmission.

Abstract: The present invention relates to a cosmetic composition using a mannosylerythritol lipid, which is a kind of glycolipid, as a stabilizer in order to prevent kojyl methylenedioxycinnamate, which is an active ingredient having various skin effects such as antiaging, whitening and antioxidation, from causing crystallization inside a dosage form. Even if the cosmetic composition according to the present invention contains a high concentration of an active ingredient, crystal precipitation does not occur in various dosage forms, and thus the functionality of the active ingredient is maximized, skin delivery is increased and the texture during use is improved.
