Abstract: An apparatus and a method for measuring a creep crack growth property using a small specimen with a micro groove are provided. The apparatus for measuring a creep crack growth property includes a lower die on which an edge of the specimen is mounted and which includes a lower die hole formed in the center thereof, an upper die coupled to an upper portion of the lower die so as to fix the specimen, and a punching unit inserted into an upper die hole formed in the center of the upper die so as to press an upper surface of the specimen, wherein a semielliptical micro groove is formed in a lower surface of the specimen to measure a creep crack growth property.

Abstract: The present invention relates to a reversible permeability measuring device for measuring magnetic characteristics and magnetic flux change in a specimen, as one of a plurality of non-destructive methods for evaluating mechanical properties. The reversible permeability measuring device of the present invention directly measures a magnetic field change induced at the surface of the specimen through the use of a magnetic potentiometer and a flux meter, thereby accurately evaluating the deterioration of materials.

Abstract: A gas station safety management system of the present invention includes a sensor network having sensors which are provided at gas station equipment, a monitoring module which receives sensing signals from the sensors, maps the gauge values of the sensing signals on a map in which the gas station equipment is described, and generates a warning signal when the sensing signals exceed a predetermined reference range, and a user interface for displaying the map, the mapped gauge values, and the warning signal on a screen.
