Abstract: Disclosed is a method for, preventing, ameliorating or treating dementia by administering a composition containing 2?-fucosyllactose. 2?-FL ameliorates brain damage caused by amyloid beta and neuroinflammation by suppressing or preventing accumulation of the amyloid beta, thus being highly effective in preventing, ameliorating and treating dementia.

Abstract: A vacuum suction head may include a holder including a through hole formed therein, a suction pad surrounding at least a portion of a side surface of the holder, and a packing pad on a lower surface of the holder. The suction pad may protrude below a lower surface of the holder. The packing pad may include a cutout part. The cutout part may allow a space between the suction pad and the packing pad such that the space and the through hole may be in fluid communication with each other.

Abstract: Disclosed is a method of adjusting the performance of a wear leveling operation depending on the pattern of a workload according to a command inputted to a storage device, thereby managing a difference in the count of erase operations between storage areas included in a memory not to exceed a limit value and enabling a wear leveling operation to be performed.

Abstract: The present invention relates to a method for increasing the productivity of 2?-fucosyllactose through various changes in culture medium composition and culturing on the basis of lactose, which is a substrate, wherein 2-fucosyllactose can be continuously produced in a high-yield at an optimum lactose concentration discovered by a culturing method of the present invention.

Abstract: Provided is a trench line for the disconnection of a solar cell, capable of effectively insulating a semiconductor layer at an upper portion of a substrate from a semiconductor layer at a side portion of the substrate and improving disconnection reliability. The trench line for the disconnection of a solar cell according to the disclosure which electrically insulates the semiconductor layers formed at the upper portion and the side portion of the substrate of the solar cell from each other, includes a plurality of unit trench lines which are disposed to intersect at an upper surface of the substrate of the solar cell. Intersecting points of the intersecting unit trench lines are positioned on the unit trench lines and are positioned at points spaced inwardly from starting points or ending points of the unit trench lines by a predetermined distance.

Abstract: An improved copy protection circuit of a data stored in a memory capable of advantageously protecting an illegal copying of a data stored in a memory such as a mask ROM (Read Only Memory) by storing a data in a security data store cell. The protection circuit includes a security data store circuit for storing a security data encoded in accordance with a chip enabling signal applied thereto, a switch circuit for outputting a switching signal controlled by the security data, and a data converting circuit for converting an input address by receiving the input address and the security data and for outputting the converted address or the input address to a X, Y-address buffer/decoder in accordance with an output of the switch circuit.
