Abstract:
Provided is a washing method. The washing method includes: setting a target water level of washing water supplied for a washing cycle; supplying washing water and measuring a time for the washing water to reach the target water level; and setting a spray time for a rinsing cycle conducted after the washing cycle based on the time measured in the step of measuring a time to reach the target water level. Adequate rinsing performance can be achieved even in a region with different water pressure.

Abstract:
Disclosed herein is a. skin external composition containing ginseng berry extract. More specifically, disclosed is a skin external composition, which contains, as an active ingredient, ginseng berry extract having the specific components and compositions, among the above-ground parts of ginseng, and thus promotes the production of collagen in the skin, shows an MMP-I inhibitory effect and, at the same time, has skin-aging inhibitory and wrinkle-reducing effects, resulting from antioxidant effects and DNA damage-protecting effects. Also disclosed is a skin external composition, which contains, as an active ingredient, ginseng berry extract, which has a skin whitening effect resulting from the effects of inhibiting melanin production and reducing pigmentation caused by UV radiation, the effects of relieving dry skin symptoms and atopic symptoms by inducing and maintaining the normal differentiation of skin keratinocytes, the effect of relieving acne and skin troubles by the regulation of sebum secretion and an anti-inflammatory effect, and makes complexion ruddy through the improvement of peripheral blood circulation to make the skin clean and clear. Also disclosed is a food composition for reducing and preventing obesity, which contains, as an active ingredient, ginseng berry extract, which increases the expression of a carnitine palmitoyl transterase-1 (CPT-I) gene, serves to transport fatty acids into mitochondria in fatty acid oxidation and promotes fat oxidation.
Abstract:
An operating method, a base station, and terminal of a cell of a first communication system for a handover between the first communication system and a second communication system are provided. The method includes, when a terminal initiates a handover between the first communication system and the second communication system, transmitting, by the base station, a message, requesting to measure a signal level of a downlink, to the terminal, when a signal level measured by the terminal falls below a preset threshold, requesting, by the base station, a handover to the second communication system over a core network, receiving, by the base station, a message, including radio channel parameters the that is required when the terminal accesses to the second communication system, from the second communication system, and forwarding, by the base station, the message, including the radio channel parameters of the second communication system, to the terminal.
