  • Patent number: 11954891
    Abstract: Provided is a method of compressing an occupancy map of a three-dimensional (3D) point cloud, and more specifically, a method of compressing an occupancy map of a point cloud in which an occupancy map image of a point cloud existing in a 3D space is compressed based on a compression quality or a patch-by-patch inspection method of the occupancy map image so that compression distortion is minimized when reconstructing the compressed occupancy map image so as to remarkably improve the quality of a reconstructed occupancy map image.

  • Publication number: 20240008460
    Abstract: The present disclosure relates to a JAK3 gene-mutated severe combined immunodeficiency animal model and a method of constructing the same. In the JAK3 gene-mutated severe combined immunodeficiency animal model of the present disclosure, the JAK3 gene is specifically deficient, the expression of cytokines is regulated by controlling the number and activity of macrophages, and the thymus, lymphocytes, and Peyer's patches, which are observed in conventional severe combined immunodeficiency animal models, particularly mini-pigs, are completely lacking. In addition, the animal model of the present disclosure can be used as a treatment model for JAK3 SCID patients, as similar phenotypes are observed in patients with human severe combined immunodeficiency caused by a JAK3 gene mutation, and can be used for artificial blood development or xenotransplantation.

  • Publication number: 20210392863
    Abstract: The present disclosure relates to a dwarfism animal model carrying an IGF-1 gene mutation and a method for generating the same. According to the present disclosure, the problem that an animal dies immediately after birth is overcome, the majority of phenotypes seen in Laron syndrome patients may be observed in the dwarfism animal model, and the dwarfism animal model has decreased expression of personality genes. Thus, the dwarfism animal model may be effectively used as a dwarfism-related disease model.

  • Patent number: 10713478
    Abstract: The present invention includes: a three-dimensional moving image generation module for generating a moving image of an experiment target person; an object extraction module for extracting the experiment target person, separately from a background, from the moving image; an object definition module for defining an object by measuring a length, a size and a weight center of the object and extracting a depth image of the object; a behaviour pattern definition module for defining a basic behaviour pattern of the object by cumulatively analyzing a movement speed and movement time of the weight center of the corresponding object, and changes in the extracted depth data when the object defined by the object definition module is extracted by the object extraction module; and a behaviour pattern analysis module for analyzing and identifying a lasting time and a frequency of the basic behaviour pattern with respect to the object.
