Abstract:
There is provided a method for direct transaction of metal scrap through enlarged collection quantities that can increase profitability by enabling to calculate a conversion price in which a weight value on a weight basis and on timing basis of scraps formed in a large quantity is reflected while making small quantities secured by scrap dealers to a large quantity by collecting, to transmit the conversion price to each dealer, to determine a sale intention, to sell the scraps to several kinds of buyers, and to sell the scraps to a dealer, a middle merchant, and a large merchant with a highest price and that can enhance productivity while minimizing a management cost by providing a large quantity of scraps to steel companies.
Abstract:
A multi-step exposure method using an electronic shutter and a photography apparatus using the same are provided. The photography apparatus includes an image sensor, and a control unit which divides an area of the image into a first area and a second area using brightness information of the acquired image, and controls so that a first row group and a second row group of the second area have different exposure times. As a result, an image with a wider dynamic range is provided.
Abstract:
The present invention relates to a novel quinoline derivative compound, an optical isomer thereof, a pharmaceutically acceptable salt thereof, and a hydrate or a solvate thereof. The novel quinoline derivative compound, the optical isomer thereof, the pharmaceutically acceptable salt thereof, and the hydrate or the solvate thereof accelerates gastrointestinal movement, and thus can effectively prevent or treat gastrointestinal mobility disorders.
Abstract:
An X-ray device is disclosed. In one embodiment, the device includes an X-ray detector and a power contactor which includes a contact terminal. The device may further include an X-ray table that provides a space into which the X-ray detector is inserted and that includes a push pin pressing the power contactor, wherein the power contactor selectively protrudes from the inside to the outside of the X-ray detector due to a pressure applied by the push pin, and the contact terminal is electrically connected to a power terminal of the X-ray table. The X-ray detector prevents exposure of the power contactor to the outside thereof when the X-ray detector is carried or transported and thus prevents a malfunction of the X-ray detector.
Abstract:
The present invention relates to novel derivatives of oxazolidinone, a method thereof and pharmaceutical compositions comprising the derivatives for use in an antibiotic. The oxazolidinone derivatives of the present invention show inhibitory activity against a broad spectrum of bacteria and lower toxicity. The prodrugs, prepared by reacting the compound having hydroxyl group with amino acid or phosphate, have an excellent efficiency on solubility thereof against water. Further, the derivatives of the present invention may exert potent antibacterial activity versus various human and animal pathogens, including Gram-positive bacteria such as, Staphylococci, Enterococci and Streptococci anaerobic microorganisms such as Bacteroides and Clostridia, and acid-resistant microorganisms such as Mycobacterium tuberculosis and Mycobacterium avium. Accordingly, the compositions comprising the oxazolidinone are used in an antibiotic.
Abstract:
Disclosed is a maskless exposure method, where it is possible to perform a more precise optical alignment using a first pattern of a maskless exposure part and a second pattern of a main reference unit, and it is also possible to reduce generation of a blur in an exposed pattern.
Abstract:
A light guide plate includes a light incident surface, a light emitting surface and a light guide surface. The light incident surface receives light from an external light source. The light emitting surface emits outward the light received through the light incident surface. The light guide surface faces the light emitting surface and includes a diffusion pattern formed thereon. The diffusion pattern includes a plurality of porous particles and a plurality of spheroidal particles, and the porous particles have pores formed therein and on surfaces thereof.
Abstract:
A multi-step exposed image acquisition method by an electronic shutter and a photography apparatus using the same are provided. The photography apparatus includes a controller configured to divide an image sensor into a plurality of areas and separately control an exposure time with respect to the plurality of areas of the image sensor and a display configured to display an image on which the exposure times for the areas has been controlled. Accordingly, a multi-step exposed image can be acquired from an image having varying brightness.
Abstract:
A method and system for providing search results only inclusive of valid webpage(s) to a user is disclosed, the method comprising: receiving a first search query from a first user; providing to the first user first search results obtained in response to the first search query; determining whether a webpage selected by the first user from the first search results is valid or not; receiving a second search query from a second user; providing to the second user second search results obtained in response to the second search query if it is determined that the webpage selected by the first user is valid; and correcting the second search results obtained in response to the second search query and providing the corrected second search results to the second user if it is determined that the webpage selected by the first user is not valid and is included in the second search results.
Abstract:
A plasma display panel including address electrodes extending in a first direction, and scanning and sustain electrodes extending in a second direction, the electrodes corresponding to discharge cells. Each of the scanning and sustain electrodes includes a transparent electrode that extends toward the other of the scanning and sustain electrode, and over the discharge cell; a main bus electrode positioned adjacent to and parallel with a barrier rib member; and a sub-bus electrode disposed between the main bus electrode and the other of the scanning and sustain electrode. Some embodiments also include an intermediate electrode disposed between the scanning and sustain electrodes. Embodiments of the disclosed plasma display panel exhibit a reduced voltage drop over the transparent electrodes of the sustain electrodes and scanning electrodes, thereby permitting the generation of a sustain discharge at a lower voltage, and a reduced time for generating an address discharge light.
