  • Patent number: 10314915
    Abstract: Disclosed is a catechin bioavailability enhancer comprising cyclodextrin as an active ingredient. Further, disclosed is a composition comprising a catechin bioavailability enhancer comprising catechin and cyclodextrin. The composition disclosed in the present specification may improve the stability of catechin which has significantly low intestinal absorption rate, and thus may improve bioaccessibility, intestinal transport rate and bioavailability of catechin. Accordingly, the improved bioavailability may further increase the effects of catechin such as the effects of reducing weight and body fat, anti-oxidative effects and anti-aging effects. The composition disclosed in the present specification having the abovementioned characteristics can be effectively used in the fields of food or pharmacy.

  • Publication number: 20190138989
    Abstract: Provided is a technical spillover effect analysis method. The technical spillover effect analysis method according to an embodiment of the present invention includes: obtaining technical co-classification information from a patent concurrently technically classified into two or more technical categories from patent data formed of a plurality of patents classified into preset technical categories; calculating the degree of the relationship between the technical categories from the technical co-classification information; and deriving a technical spillover effect for the technology classification using the degree of the relationship between the technical categories.

  • Patent number: 9307595
    Abstract: A light emitting device driving module may be provided that includes: a light emitter including a first light emitter and a second light emitter connected to the first light emitter; a rectifier which receives an AC power and outputs a rectified voltage; and a controller which receives the rectified voltage from the rectifier and controls on/offs of the first light emitter and the second light emitter in accordance with a magnitude of the rectified voltage. The light emitting device driving module according to the embodiment controls the on/offs of two or more kinds of the light emitting devices by using the AC power, and thus, drives the light emitting device in such a manner as to have a high color rendering index.
