The present invention relates to a device for measuring deformation ratios of structures and to a deformation-ratio-measuring method for structures employing the same. More specifically, the device for measuring deformation ratios of structures of the present invention comprises a photonic crystal layer containing nanoparticles disposed at predetermined intervals. According to the present invention, when diverse industrial structures deform due to factors such as loading in use, structural colour changes or magnetic changes in the affected portion are measured such that accurate measurements can be taken of whether or not deformation has occurred and of the deformation ratio in a way which is straightforward and easy, and these measurements can be used to prevent safety incidents from occurring due to excessive deformation of structures.

The present invention relates to a thermoelectric nanowire which is manufactured by laminating an oxide layer and a thermoelectric material, which have different coefficients of thermal expansion, on a substrate, and enabling a single-crystal thermoelectric nanowire to be grown from the thermoelectric material using the compressive stress caused by the difference in thermal expansion coefficients. The present invention also relates to a method for manufacturing the thermoelectric nanowire. The method for manufacturing the thermoelectric nanowire comprises the steps of: providing a substrate on which an oxide layer is formed; forming a plurality of nanoparticles consisting of Al, Ag, Fe, or oxides thereof on the oxide layer; forming a thermoelectric thin film having thermoelectric characteristics on the oxide layer such that the thermoelectric thin film contains the plurality of nanoparticles formed on the oxide layer; performing a heat treatment on the substrate on which the thermoelectric thin film is formed, to enable the thermoelectric nanowire containing the plurality of nanoparticles to grow; and cooling the substrate at room temperature after the heat treatment process.
Abstract:
The present invention relates to a method of suppressing grain growth in an AL-ZN-MG-based aluminum alloy billet for thixoextrusion which is characterized by comprising a Sc-adding step of adding Sc of 0.05~0.15% to molten metal, and a heating step including more than 3 steps of heating treatment processes for the billet moulded from the molten metal. Here, Sc may be added to the molten metal as a master alloy of Al-2 weight percent, and there may be 5 to 10 minutes of sustain time after completion of each heating process. The grain growth rate of the aluminum alloy billet manufactured according to the method of the present invention is below 10% based on the area of the initial grain. Therefore, the method of the present invention is economical because the AL-ZN-MG-based aluminum alloy billet having the low grain growth rate can be manufactured without an additional equipment or cost. Besides, the method offers a billet that has a fine and uniform grain on the inside and the outside.
Abstract:
The present invention relates to an adipocyte differentiation medium composition and a method of differentiating preadipocytes into adipocytes using the same. The adipocyte differentiation medium composition is characterised in that it comprises insulin, DHEA (dehydroepiandrosterone) and histamine. Said medium composition achieves smoother distribution and more stable settling of differentiated adipocytes in comparison with conventional adipocyte differentiation medium compositions, thereby maximising adipocytic cell viability. Furthermore, the DHEA and histamine used in said medium composition is more cost-efficient than conventional adipocyte differentiation medium compositions that rely on dexamethasone and isobutylmethylxanthine.

Abstract:
A method for designating a dual region according to one embodiment of the present invention comprises the steps of: enabling a terminal which is in communication with a first network to calculate a channel state threshold value corresponding to data; comparing the channel state value of the first network and the channel state value of the second network, acquired using a pilot signal of a second network, with the channel state threshold value; calculating a network evaluation score of the first network; comparing the network evaluation score of the first network with a network evaluation threshold value for designating a dual region, if the channel state value of the first network and the channel state value of the second network are larger than the channel state threshold value; and determining whether to designate a dual region in accordance with the result of the comparison using the network evaluation threshold value. The method of the present invention can reduce service cutoff or delay time during inter-radio access.
