Abstract: A composition for preventing or treating synucleinopathies, which includes efavirenz or a salt or solvate thereof and a pharmaceutically acceptable carrier, is provided. The composition is useful in preventing or treating synucleinopathies, such as Parkinson's disease, dementia with Lewy bodies, and multiple system atrophy, because the composition serves to hinder cell-to-cell transmission of alpha-synuclein, prevent intracellular aggregation of ?-synuclein, and inhibit transmission of aggregated ?-synuclein.

Abstract: A linear vibrator includes a casing defining an internal space of the vibrator, a bracket disposed under the casing and having a coil, to which electricity is applied to induce a magnetic field, an oscillator having a magnet received in a hollow portion of a yoke, one end of which is closed, and a cylindrical weight coupled onto the circumference of the yoke, and a spring member coupled with an upper portion of the casing to elastically support the oscillator such that the oscillator is movable in a linear motion, wherein the weight is provided with a plurality of circumferential recesses in which a rotary member is rotatably inserted while being in contact with a sidewall of the casing.

Abstract: A linear vibration generator is disclosed. The linear vibration generator may include: a stator having a coil, which induces a magnetic field when an electric current is applied; an oscillator having a magnet, which has one side facing the coil; a spring member, which is joined to the stator, and which elastically supports the oscillator such that the oscillator moves linearly; a damper, which prevents the oscillator from contacting the stator according to the linear motion of the oscillator; and a guide portion, which guides the linear motion of the oscillator. This linear vibration generator makes it possible to generate stable linear vibration, prevent generation of touch noise when the oscillator impacts the stator, and prevent right/left vibration due to an external impact.

Abstract: Disclosed herein is a linear vibrator. The linear vibrator includes a casing, a vibration unit, a bracket, a circuit board, a coil unit, a lead wire and a soldering part. The casing defines an internal space therein. The vibration unit is provided in the casing and vibrates upwards and downwards. The bracket supports the casing and the vibration unit. The circuit board is provided on the bracket. An electric circuit and a plurality of electronic devices are provided on the circuit board. The coil unit is mounted to the central portion of the circuit board in a perpendicular direction, so that power is applied from the circuit board to the coil unit. The lead wire extends from the lower end of the coil unit and is electrically connected to the circuit board.
