Abstract: Provided is a computer. The computer includes: a plurality of parts including heat-generating components that generate heat during operation; a case in which the parts are installed; and one or more heat-dissipating plates separated from the case by a predetermined distance and facing the case; wherein the heat-generating components include a central processing unit and a power supply, and the central processing unit and the power supply are each thermally connected to the heat-dissipating plates so that heat generated by the central processing unit and the power supply can be dissipated to the outside of the case via the heat-dissipating plates. Accordingly, the heat-generating components installed in the case can be noiselessly and efficiently cooled without using cooling fans.

Abstract: The present invention relates to a promoter directing high levels of expression of a gene in plant storage roots, derived from the sweet potato MADS-box gene, a vector directing high levels of expression of a gene in plant storage roots comprising the same and a transient assay method expressing a foreign gene transiently in plant storage roots using the same vector. The promoter according to the present invention can induce high levels of expression particularly in plant storage roots. Therefore the present invention is very useful for the development of transgenic plants to produce valuable materials in large quantities in plant storage roots.
