Abstract: Disclosed is a context-aware real-time spatial intelligence provision system that estimates the locations of persons or things captured in a video by extracting objects representative of the persons and the things from the video captured by viewing a real space and placing the extracted objects in a virtual space to which a digital twin technique is applied. The disclosed context-aware real-time spatial intelligence provision system allows people to keep the distance between each other indoors, thereby preventing the spread of an infectious disease such as COVID-19.

Abstract: Disclosed are an open-porous metal foam and a method for manufacturing the same. An open-porous metal foam according to an exemplary embodiment of the present invention is made of an iron-based alloy including 15 wt % or more of chrome and 5 wt % or more of aluminum. The open-porous metal foam is a semi-product that is formed of iron or the iron-based alloy that does not include chrome and aluminum or includes a smaller amount of chrome and aluminum in the powder when manufacturing, and the surface and the open pore thereof are uniformly coated with the powder of the iron-chrome-aluminum alloy and the organic binding agent. When heat treatment is performed under a reduction atmosphere, sintering is performed.
