Abstract: A display apparatus and a controlling method thereof are provided. The method includes sensing a first touch, in response to the first touch being sensed, transmitting a first signal corresponding to the first touch to at least one peripheral display apparatus, receiving a second signal corresponding to a second touch from a peripheral display apparatus where the second touch corresponding to the first touch is sensed from among the at least one peripheral display apparatus, and performing communication connection with the peripheral display apparatus where the second touch is sensed, using the first signal and the second signal.

Abstract: The present invention relates to a head and neck simulation phantom device for simulating the head and neck of a body, the phantom device including: a flat type first plate having a first insertion groove formed on one surface thereof; a flat type second plate disposed to come into contact with the other surface of the first plate and having a second insertion groove formed on the contacted surface with the other surface of the first plate in such a manner as to correspond to the first insertion groove; and a plurality of teeth simulants inserted into the first insertion groove and the second insertion groove and for simulating the teeth of the body.

Abstract: Provided is a transdermal drug delivery system, which is a delivery system for transdermal absorption, having a multi-lamellar emulsion structure, including: lipids including long-chain amides, sterols, fatty acid and fatty alcohol; an emulsifier; oil; and at least one drug for transdermal administration. The transdermal drug delivery system in a multi-lamellar emulsion structure, according to the present invention, has a lamellar structure in which a layered structure visible in stratum corneum intercellular lipids of the human body is repeated, and thus has an excellent skin barrier effect and enables a drug to be effectively partitioned through skin lipids, thereby obtaining an excellent drug delivery effect.

Abstract: Methods and apparatuses for managing rule based on informal data are provided, one of methods comprises, receiving, by a rule management apparatus, informal data representing a rule, analyzing, by the rule management apparatus, the informal data, generating, by the rule management apparatus, formal data that can be processed by a rule engine of the rule management apparatus, using results of the analysis of the informal data, selecting, by the rule management apparatus, one or more items to be corrected for setting the rule from the formal data with reference to a target thesaurus relevant to the rule and processing, by the rule management apparatus, the formal data with the selected items corrected, using the rule engine.

Abstract: Disclosed is a stack for simulating a cell voltage reversal behavior in a fuel cell. The stack is configured to have a structure in which a separator of a portion of a plurality of cells in the stack have an inlet of a hydrogen flow field partially blocked to induce hydrogen starvation only in the portion of the plurality of cells.

Abstract: Disclosed is a pinhole inspection apparatus, system and method for a membrane electrode assembly of a fuel cell, which can easily detect the position of a pinhole using water and a pH test paper from discoloration caused when the water is in contact with the pH test paper through the pinhole, thus solving the existing problems and allowing the membrane electrode assembly to be reused after the inspection. In particular, a lower fixture is configured to support the membrane electrode assembly and water is uniformly distributed on an upper surface of the membrane electrode assembly. A pH test paper is inserted between the membrane electrode assembly and the lower fixture and discolored upon coming in contact with water that passes through a pinhole in the membrane electrode assembly, thus detecting the presence and position of the pinhole.

Abstract: A membrane-electrode assembly (MEA) for fuel cells includes an electricity-generating array including an anode, a cathode, and an electrolyte membrane. A subgasket array includes an anode subgasket surrounding a periphery of the anode and a cathode subgasket surrounding a periphery of the cathode. A junction array includes a polar junction and a nonpolar junction surrounding a periphery of the electrolyte membrane and attaching the anode subgasket and the cathode subgasket to each other.

Abstract: The present invention provides an apparatus and method for non-destructive measurement of bending stiffness of a gas diffusion layer (GDL) for a fuel cell by measuring a sagging length of a GDL sample, which can be used for a fuel cell, without damaging or destroying the GDL sample.

Abstract: A method of clamping a fuel cell stack includes a stack preliminary clamping step, a stack pre-treatment step of performing a gas flow rate variation cycle or a clamping pressure variation cycle, wherein the gas flow rate variation cycle repeatedly changes a flow rate of a gas supplied to an anode and a cathode included in the preliminarily clamped stack, and wherein the clamping pressure variation cycle repeatedly increases and decreases the clamping pressure by pressurization and pressure release of the preliminarily clamped stack using the pressure tool, and a stack main clamping step of correcting a variation in clamping pressure occurring due to a variation in thickness of a gas diffusion layer to mainly clamp the stack after the stack pre-treatment step.

Abstract: When a multi-step process reaction is carried out in a solution, it generally requires several treatments and purification procedures to go through with after the reaction, however, the inventive method for preparing 2,2?-disubstituted-3,4-dihydro-7,8-disubstituted-6-amino benzopyran derivative using a solid-phased synthetic method simplifies the treatment and purification procedures after the reaction, which makes possible to efficiently construct numerous drug-like libraries.
