Abstract: The present invention relates to an acellular skin substitute for breast reconstruction and a preparation method therefor. In the present invention, an acellular skin substitute may be prepared through the removal of epidermal layers and an acellularization process, in which the use of a proteolytic enzyme and a surfactant is excluded. In addition, since the acellular skin substitute is cut into suitable sizes and shapes to cover a breast reconstruction implant through design software and then cut out with a CNC machine, the time for breast reconstruction surgery may be reduced, and since no dead space is formed after suturing, the incidence of seromas may be reduced. Accordingly, the side effects of surgery may be lessened.

Abstract: A hybrid tag interface system and an interfacing method therefor are provided. First codes for an object from a wireless recognition tag containing the first codes are received through wireless communication, a second code for the object from an image tag expressing the second code by using a 1- or 2-dimensional image is read through optical contact, and then information on the object is calculated from the first codes and the second code based on their correlation. By doing so, automatic recognition and visibility can be maximized using the hybrid tag combining a wireless recognition tag and an image tag.
