摘要:
A method of alarming an abnormal state of a line of an automated manufacturing system using a programmable logic controller (PLC) signal pattern is provided. The method includes obtaining a plurality of change sequences of a plurality of PLC signals for control of the line in a normal operating system by repeating a cycle for which the line is sequentially controlled by the PLC signals that are transmitted and received between a PLC and the line according to an operation of PLC internal logic; acquiring a reference sequence from a plurality of the change sequences, wherein the reference sequence indicates an order of change of a plurality of the PLC signals for control of the line in a normal operating state; and determining whether the line is in a normal operating state or an abnormal operating system based on whether or not the reference sequence is matched with a change sequence of a plurality of PLC signals for control of the line in use after the acquisition of the reference sequence, and outputting a determination result.
摘要:
Disclosed are a PLC (Programmable Logic Controller) symbol structure for a PLC code for automatically generating an input/output model, and a simulation apparatus and a simulation method for testing the PLC code using the same. In one embodiment, a computer-readable recording medium records a PLC code including a plurality of PLC symbols, wherein each of the PLC symbols includes a plurality of levels identified by an identifier, and a computer automatically generates an input/output model using the structure of each of the PLC symbols, thereby performing a simulation for testing the PLC code. The PLC symbol structure according to one embodiment systematically contains information required for automatically generating the input/output model, making it possible to automatically generate the input/output model for testing the PLC code in an easier manner without knowledge of simulation and modeling, and reducing the time consumed and the labor required for generating the input/output model.
摘要:
An apparatus and method for distinguishing between tack-welding and welding are provided. The apparatus for distinguishing between tack-welding and welding includes: a current sensor configured to detect arc current of a welder; and a distinguish control unit configured to distinguish whether a welding operation performed by the welder is tack-welding or welding based on the arc current detected by the current sensor for a predefined period of time. Accordingly, the amount of work performed by a welding worker can be fairly and accurately evaluated.

The present invention relates to a composition for inhibiting cellular senescence, comprising N-[2-(cyclohexyloxyl)-4-nitrophenyl]-methanesulfonamide.
摘要:
The present invention relates to a pharmaceutical composition for promoting the healing of wounds, containing lysophosphatidic acid and an adenylyl cyclase inhibitor as active ingredients, and more particularly, to a pharmaceutical composition which contains an adenylyl cyclase inhibitor and which promotes the healing of wounds in senescent cells or aged persons having physiological characteristics different than those of young cells or young persons. In addition, the present invention relates to a method for promoting the healing of wounds involving treating a wounded person with an effective dose of the lysophosphatidic acid and adenylyl cyclase inhibitor.
摘要:
The present invention relates to a composition for the treatment and improvement of diabetes comprising caveolin as an active ingredient and a method for treating diabetes using the same, more precisely a composition comprising caveolin-1 as an active ingredient for the treatment and improvement of type II diabetes which is age-dependent but not showing obesity symptom and a method for treating diabetes using the same. The treatment method and composition of the present invention is very effective in improving and treating diabetes by regulating insulin sensitivity by increasing caveolin level in muscle tissues of type II diabetes patient which is age-dependent but not showing obesity symptom.
摘要:
The present invention relates to a composition for inhibiting cellular senescence, comprising N-[2-(cyclohexyloxyl)-4-nitrophenyl]-methanesulfonamide. During the progression of cellular senescence, the expression of COX-2 was decreased, whereas the enzymatic activity of COX-2 was increased, and the cellular senescence regulatory effects of the three selective COX-2 inhibitors had no connection with the concentration of intracellular reactive oxygen species, the activity of NF-κB and the amounts of p53 and p21 proteins. Rather, it was found that the three selective COX-2 inhibitors regulated the expression of caveolin-1 at the transcriptional level and regulated the intracellular total cholesterol concentration, and these results were closely connected with the cellular senescence regulatory effects of the three selective COX-2 inhibitors.
摘要:
The sequences of a pair of human proteins, trichohyalin and transglutaminase-3, in addition to the sequence of the mouse transglutaminase-3 protein, have been discovered. The enzyme transglutaminase-3 is used to cross-link the structural protein trichohyalin in order to form a gel.
