Abstract:
An apparatus and a method for handover between a broadband wireless communication system and a heterogeneous communication system are provided. An operating method of a base station for the handover between a broadband wireless communication system and a and a heterogeneous communication system includes when a terminal enters a border cell, sending 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 a handover, to a corresponding heterogeneous communication system, over a core network, receiving a message, including channel allocation information for the handover, from the corresponding heterogeneous communication system, and forwarding the message, including the channel allocation information, to the terminal. Hence, when the terminal gets out of the service coverage area of the broadband wireless communication system, it can be handed over to the heterogeneous communication system seamlessly.

Abstract:
The present invention relates to a ginseng mixed composition with improved bioavailability of saponin. Further, the present invention relates to a method for improving saponin bioavailability of a subject comprising: administering to the subject an effective amount of at least one extract selected from a Schizandra chinensis extract and a Liriope platyphylla extract that improves saponin bioavailability in the subject.
Abstract:
In a semiconductor device having an enlarged contact area between a contact structure and a substrate, the substrate may include a first region on which a conductive structure is arranged and a second region defining the first region. The first region may include a multi-faced polyhedral recess of which at least one of the sidewalls is slanted with respect to a surface of the substrate. An insulation layer may be formed on the substrate to a thickness that is sufficient to cover the conductive structure. The insulation layer has a contact hole that may be communicated with the recess. The active region of the substrate is exposed through the contact hole. A conductive pattern is positioned in the recess and the contact hole. Accordingly, the contact resistance at the active region of the substrate may be kept to a relatively low value even though the gap distances and line width of pattern lines are reduced.
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 oscillatory wave generating unit and an oscillatory wave sensing unit are installed at both ends of a refrigerant pipe of an evaporator of the cooling system, an amount of frost formed on the refrigerant pipe is determined by comparing a wave form of an oscillatory wave generated from one end of the refrigerant through the oscillatory wave generating unit and a wave form of the oscillatory wave sensed by the other one end of the refrigerant through the oscillatory wave sensing unit, and whether or not a defrosting operation is performed is determined by a result of the determination. The cooling system increases the accuracy in sensing the amount of the frost formed on the evaporator of a refrigerator, a Kimchi refrigerator, or an air conditioner, and respectively starts and ends the defrosting operation at proper points of time, thus enhancing a heat-exchanging performance and increasing energy efficiency.
