Abstract: The present disclosure relates to a cosmetic composition containing an extract of Cyperus rotundus extracted using warm microbubbles. The extract inhibits nitric oxide (NO) production and exhibits excellent anti-inflammatory efficacy by inhibiting the expression of interleukin 6 (IL-6), cyclooxygenase-2 (COX-2), interleukin-1? (IL-1?), and tumor necrosis factor-? (TNF-?), which are inflammatory expression factors. In addition, the extract enhances the expression of aquaporin-3 (AQP-3), hyaluronan synthase 2 (HAS-2), claudin-1 (CLDN-1), cadherin 1 (CDH1), filaggrin (FLG), and involucrin (IVL), which are genes related to the skin barrier and moisturizing. Thus, when using the extract for cosmetic products, excellent effects can be exhibited in skin soothing, moisturizing, enhancement of the skin barrier, relief of irritation such as erythema, relief of pruritus, and the like, so the extract can be usefully applied to multi-care products that improve skin conditions.

Abstract: The present disclosure relates to a system and method for detecting an aircraft energy anomaly using an artificial neural network learning model. A system for detecting an aircraft energy anomaly using an artificial neural network learning model according to the present disclosure includes an input interface device for receiving ADS-B (Automatic Dependent Surveillance-Broadcast) data, a memory storing a program which generates a specific energy feature for energy state analysis by extending the ADS-B data through a preprocessing, and a processor for executing the program, wherein the processor generates an energy distribution model by the use of the specific energy feature, and performs artificial neural network-based energy anomaly learning.
