Abstract: A structure for a physical unclonable function using spontaneous chiral symmetry breaking and a method of preparing the same are described, in which a chiral random pattern, which is unclonable and is observable with an optical microscope and a mobile phone camera, is formed using chiral photonic crystals in which chiral symmetry breaking occurs and is applied to a physical unclonable function (PUF), thereby attaining high encoding capacity, high recognition rate, and security while achieving high performance in reproducibility, uniqueness, unpredictability, and reconfigurability, and forming a desired pattern through a conventional photolithography method.

Abstract: Disclosed is a method and apparatus for quantifying severity of infectious disease based on a vision transformer using a chest X-ray (CXR) image. Here, a method of quantifying severity of infectious disease based on a vision transformer includes receiving an input CXR image; extracting a feature map from the received input CXR image using a pretrained neural network; classifying a lesion in the input CXR image using the vision transformer based on the extracted feature map; and quantifying severity of the input CXR image based on the extracted feature map and the classified lesion.

Abstract: Disclosed is an inductive knowledge graph embedding method and system through a relation graph. An inductive knowledge graph embedding method performed by a knowledge graph embedding system may include training a graph neural network-based knowledge graph embedding model using a knowledge graph and a relation graph generated from the knowledge graph; and performing link prediction for the knowledge graph that includes a new relation and a new entity through the trained graph neural network-based knowledge graph embedding model.

Abstract: Disclosed is a random sampling-based collective classification method and system for Sybil account detection. A random sampling-based collective classification method performed by a collective classification system may include performing a first collective classification using training data; constructing sampled new training data by randomly extracting a portion of the entire nodes based on a label assigned to each node according to a result of performing the first collective classification; performing a second collective classification using the constructed new training data; and applying a posterior score difference of each node computed through the first collective classification and the second collective classification to a prior score of each node to be used for training data at a next iteration.

Abstract: A method of preparing a food composition for an egg fluid substitute or for a milk substitute is described, including a step of lysing microorganisms, and corresponding food compositions prepared by such method. The egg fluid substitute or milk substitute changes into a gel having properties similar to egg fluid when heated and exhibits excellent foaming performance, and can replace egg fluid in a wide range of food applications, including confectionery and baking. The described method enables the production of an egg fluid substitute or milk substitute in an environmentally friendly and sustainable manner, and provides a method for utilizing nutritionally valuable microorganisms as an egg fluid substitute or a milk substitute, as well as contributing to the food industry by expanding the choice of food ingredients.
