Abstract:
Disclosed herein is a chip for inspecting toxicity and efficacy, including: a first substrate including fitting holes formed at corners thereof; and a second substrate including gap forming members formed at corners thereof corresponding to the fitting holes to form a gap between the first substrate and the second substrate, and protrusions formed on the gap forming members corresponding to the fitting holes and fitted in the fitting holes. The chip for inspecting toxicity and efficacy is advantageous in that alignment of the chip can be easily performed, in that problems with the emission of fluorescence or the penetration of measuring light in the chip can be solved, and in that the cost of producing the chip can be reduced.
Abstract:
A handover method at a source eNB (enhanced Node B) of a mobile communication system is provided. The method includes, in case a request message for providing content is received from UE (User Equipment), checking whether the content is stored in a cache thereof, and therefore transmitting the content to the UE, in case a handover request message is received from the UE, transmitting a content confirmation request message, which requests confirmation of whether the content is stored in a cache, to a target eNB to which the UE is to be handed over, and in case a content confirmation response message is received from the target eNB, transmitting context information, which is information about contents offered to the UE, to the target eNB.
Abstract:
Provided are an apparatus and method for controlling program conversion according to program protection information. The method for controlling conversion of a broadcasting program includes: demultiplexing a broadcasting program into broadcasting program data and program protection information; encrypting the broadcasting program data based on distribution condition of the program protection information when recordation of the broadcasting program data is requested; and recording the encrypted broadcasting program data.
Abstract:
There is provided a micro-ejection device including: an ejector ejecting a fluid; and a body having an installation space in which the ejector is installed, wherein the installation space is provided with a guide unit inducing a line-contact or a point-contact between the ejector and the body.
Abstract:
The present invention relates to novel hydrogenases isolated from novel hyperthermophilic strains belonging to Thermococcus spp., genes encoding the hydrogenases, and methods of producing hydrogen using strains having the genes. According to the hydrogen production methods of the invention, a large amount of hydrogen can be produced merely by culturing the strains in specific culture conditions. Thus, the methods of the invention have advantages in that they are more economic and efficient than existing hydrogen production methods and can produce hydrogen even at high temperature.
Abstract:
There are provided an electronic paper display device and a method of manufacturing the same. The electronic paper display device includes: a lower substrate having lower barrier ribs formed thereon, the lower barrier ribs forming cells for receiving electronic paper display elements; electronic paper display elements mounted in the cells of the lower substrate and having optical and electrical anisotropy; and an upper substrate formed to cover the lower substrate and including upper patterns bonded to the lower barrier ribs so as to secure a fluid moving path of the cell.
