Disclosed are a combination of active components inducing synergistic effects of multi-targeting and a use thereof. More particularly, disclosed are a functional food composition, a cosmetic composition, a pain-suppressive composition, and a composition for treatment or prevention of pruritus or atopic dermatitis, which comprise as active components, two or more components selected from a group consisting of (a) a 5-hydroxytryptamine subtype 2 (5-HT2) receptor antagonist; (b) a P2X receptor antagonist; and (c) any one of a glycine receptor agonist, a glycine transporter (GlyT) antagonist, a gamma-aminobutyric acid (GABA) receptor agonist, and a GABA transporter 1 (GAT1) antagonist.

Combination of effective substances causing synergistic effects of multiple targeting and use thereof

Disclosed are a novel benzamide derivative and pharmaceutical use thereof, and more particularly, a novel benzamide derivative having a structure of Formula 1 or pharmaceutically acceptable salts thereof, and a composition for prevention or treatment of pain or itching including the above material. The novel benzamide derivative and pharmaceutically acceptable salt thereof according to the present invention exhibit excellent pain-suppressive effect and, in particular, pain-suppressive effect in not only a neuropathic animal model but also other models such as a formalin model, and therefore, may be used in suppression of different pains such as nociceptive pain, chronic pain, etc. Further, since it was demonstrated that the present invention displays anti-pruritic efficacy even in an itching model, to which a mechanism and treatment concept established with respect to pain is applied, the present invention may also be effectively used in radical treatment of atopic dermatitis by applying the inventive product to an anti-pruritic composition in order to suppress an initial itching stage and treat symptoms thereof, thus preventing skin damage or inflammation after the scratching stage.

Benzamide derivative and use thereof

A stereo camera system for obtaining a stereo image of an object to measure distance between the stereo camera system and the object is provided. The stereo camera system comprises a camera and a prism arranged at a desirable distance from the front side of the lens of said camera . The prism may be a delta shaped biprism having a base , a first incline and a second incline , in which both the first incline and said second incline obliquely face the lens of said camera . Alternatively, the prism may be a trigonal pyramid shaped triprism having a base and three inclines, in which the three inclines obliquely face the lens of said camera. The camera may be a charge coupled device camera. The present invention also relates to a distance measurement system and a distance measurement method for measuring distance between the stereo camera system and an object using disparity of a stereo image of the object.

A holographic interference exposing device using a visible laser source and a chopper to easily align the optical system while confirming the light path of the laser beam with the naked eye. The exposing device comprises a main laser source generating a short wavelength laser beam, a beam splitter for splitting the laser beam into two laser beams to cause a difference in the light path of the laser beam and to form an interference fringe on a semiconductor substrate, mirrors for guiding the laser beam to the beam splitter, and mirrors for focusing the two laser beams on a surface of the semiconductor substrate, an auxiliary laser source generating a long wavelength laser beam, and a chopper making the light path of the long wavelength laser beam get together with that of the short wavelength laser beam. The auxiliary laser source generates a visible laser beam having a wavelength longer than that of an ultraviolet laser beam.

Holographic interference exposing device

The photoelectro-chemical etching system of compound semi-conductor is disclosed. The system comprises a laser generator, a shutter to cut off laser beam, a laser beam chopper, a secondary high reflection mirror, a beam expander, a waveform generator, a chopper controller, a potentiostat to apply the reverse or forward voltage to the optical glass cell. Instead of applying the reverse-bias voltage to a semiconductor material, the reverse and/or forward voltage with a uniform pulse period is applied so that homogeneous and damage-free surface is obtained and etching process is made available in a more efficient manner.
