Abstract: A communication apparatus is provided to include an apparatus enclosure that includes a substrate seating surface and at least one or more connection grooves formed on the substrate seating surface, a first printed circuit board disposed on the substrate seating surface, a second printed circuit board disposed on the substrate seating surface on one side of the first printed circuit board, and at least one or more connectors disposed within the connection groove and configured to electrically connect the first printed circuit board and the second printed circuit board.

Abstract: The present invention relates to a signal shielding apparatus and an antenna apparatus including same, and in particular, comprises a shield cover which is stacked and disposed on a printed board assembly (hereinafter, abbreviated to “PBA”), in which a plurality of signal-related components are mounted on one side thereof to prevent leakage of a signal from the plurality of signal-related components, wherein a grooved shield cover seating groove is formed in one surface of the PBA, and an insertion end insertably seated in the shield cover seating groove is integrally formed in the other surface from among one surface and the other surface of the shield cover, the other surface facing the one surface of the PBA, thereby providing advantages in that an increase in the manufacturing cost may be prevented, EMI shielding may be facilitated, and heat dissipation performance may be significantly improved.

Abstract: The present invention relates to Rhizobium sp. KB10 strain having properties of promoting growth of Botryococcus braunii, which is an alga capable of producing biodiesel, and also enhancing production performance of biodiesel. Mores specifically, it relates to novel Rhizobium sp. KB10 strain which has properties of promoting growth of Botryococcus braunii used for biodiesel production and also enhancing content of C18 (i.e., oleate) corresponding to high quality biodiesel component as much as 900%. By using root colonizing bacteria like Rhizobium, it is possible to promote effectively the slow cell growth of Botryococcus braunii and increase as much as possible the oleate amount, which is a high quality biodiesel component. Further, by carrying out mixture culture using such bacteria, problems associated with contamination by other microorganisms during a process of producing biodiesel by culture in an outside environment can be dramatically solved.

Abstract: Provided are a new microalgae strain and a use thereof, and more particularly, Ettlia sp. YC001 (KCTC 12109BP) having high carbon dioxide fixability, lipid productivity and carotenoid productivity, and a use thereof. The strain may be used for producing high quality biodiesel by controlling a lipid content and a composition ratio of a fatty acid according to culture conditions and/or culture time, and may be easily used for industrial uses, for examples, cosmetics, health foods, and medicines since large amounts of carotenoid and pigments are accumulated in cells.

Abstract: There is provided a method of producing biodiesel without drying and lipid component extraction steps in an alcohol-rich condition. Also, there is provided a method of effectively producing biodiesel without a catalyst under optimal conditions for transesterification. Production cost and time are reduced by reducing the number of processes, and biodiesel yield is increased.
