Abstract:
A chemical mechanical polishing (CMP) slurry and a chemical mechanical polishing (CMP) apparatus and method reduce defects, such as scratches, while maintaining a high polishing rate of a target film to be polished through a CMP process. The CMP slurry includes a ceria-based abrasive having a concentration of 0.001-10 percent by weight and a silica-based abrasive having a concentration of 1-24 percent by weight.
Abstract:
An LCD has a drive power supply structure simplified to simplify manufacturing processes of LCDs and to reduce manufacturing costs thereof. The LCD includes a liquid crystal panel, a drive unit, a controller, a backlight drive unit, and a drive voltage generator. The liquid crystal panel includes image display regions. The drive unit drives gate and data lines in the panel. The controller controls the drive unit using image data and synchronization signals from outside. The drive voltage generator is provided on a system or at least one source printed circuit board on which at least one of the drive unit or the controller is formed and converts a voltage level of a drive power provided from outside to generate drive powers of different voltage levels and provides the drive powers to the drive unit, the controller, and the backlight drive unit.

Abstract:
The present invention relates to a gene construct which is capable of achieving efficient production of an antimicrobial peptide in a microorganism, and a method for efficient mass production and separation of an antimicrobial peptide using the same. The gene construct of the present invention has a translationally coupled configuration of two independent and separate cistrons which encode an acidic peptide and a basic antimicrobial peptide, each having an opposite charge, under the control of a single promoter. The translationally coupled acidic peptide and basic antimicrobial peptide undergo charge-charge interaction simultaneously with expression thereof to neutralize the potential cytotoxicity of the antimicrobial peptide, resulting in prevention of antimicrobial peptide-mediated killing of host microorganisms. In addition, a conjugate of the acidic peptide and the antimicrobial peptide can be separated without chemical or enzymatic treatment. Therefore, it is possible to achieve easy mass production of antimicrobial peptides from recombinant microorganisms.
Abstract:
A detachable mobile seat includes a first part connected to a motor; a second part attached to the seat; and two links, each connected to the first part, the second part, and a wheel. The links transfer movement of the first part to the wheels. The first part includes a shaft connected to the motor, and two nuts disposed around the shaft that have screw threads in opposite directions and move along the shaft in response to operation of the motor. Each link includes a first link connected to the second part and to the nut, and a second link connected to the nut and to the wheel. The end of each second link that is nearest the wheel is rotatably connected to a connecting arm that has a rotating bar that rotates the wheel in response to operation of the links.
Abstract:
Ultralong carbon nanotubes can be formed by placing a secondary chamber within a reactor chamber to restrict a flow to provide a laminar flow. Inner shells can be successively extracted from multi-walled carbon nanotubes (MWNTs) such as by applying a lateral force to an elongated tubular sidewall at a location between its two ends. The extracted shells can have varying electrical and mechanical properties that can be used to create useful materials, electrical devices, and mechanical devices.
Abstract:
The present invention relates to a neuronal differentiation method of adult stem cells using small molecules, more particularly to a method for inducing differentiation of adult stem cells into nerve cells using small molecules, which enables effective differentiation into nerve cells and, thus, is useful in treating intractable CNS disorders such as Parkinson's disease, dementia, Alzheimer's disease and spinal cord injury.

Abstract:
A method to correct a phase of a data sector due to rotational slip of a disk includes measuring a difference in the phase of a servo sector between a plurality of disks and adjusting an amount of cylinder skew of a logical data sector between the plurality of disks based on the measured difference in the phase of a servo sector between the plurality of disks.
Abstract:
In a method of improving read hits to pre-fetch data stored in a memory associated with a hard disk drive (HDD). The method includes; receiving a read command indicating a target sector on a disk in the HDD, obtaining a latency time in relation to a movement time and a search time, and during the latency time, reading pre-fetch data from the disk at a current position of a magnetic head and storing the pre-fetch data in the memory before executing the received read command.
