This technology relates to a wireless communication interface with physical random number generation capability, including a wireless communication antenna, a divider that separates received signals into seed communication signals and seed random number signals, a communication processing module, and a random number generation module.
Existing wireless communication devices required separate hardware for random number generation, leading to complex structures and difficulties in ensuring security.
To address this issue, this technology utilizes the received wireless signal itself as a seed to generate physical random numbers, thereby simultaneously enabling random number generation for both communication and security without requiring additional components.
This technology relates to an authentication server, method, program, and metaverse server that authenticates the authenticity of a product using recognition tag information and provides a metaverse virtual product creation key or NFT creation information based on the authenticated product.
Existing authenticity verification methods had limitations in preventing counterfeiting and in digital utilization because they could not link offline products with digital assets.
To address this, this technology authenticates genuine products by matching tag information with stored information and, by creating virtual products and NFTs based on those results, ensures both product authenticity and digital assetization.

This technology relates to a method for operating an electronic device that identifies and evaluates a user's emotions and symptoms through conversations with an AI chatbot and provides therapeutic content tailored to depression and anxiety disorders.
Existing counseling services have struggled to consistently provide appropriate therapeutic content in response to changes in a user's symptoms.
To address this, this technology enables personalized management by having a user-specific chatbot evaluate depression and anxiety disorders during each conversation and provide therapeutic content based on the results.
This technology relates to an antibody that specifically binds to human Fc alpha receptors and its immunologically active fragments. It maximizes the mechanism of action of various antibody therapeutics by binding to Fc alpha receptors on effector cells while maintaining the IgG format.
Conventional IgA antibodies had limitations in utilizing effector functions, making it difficult to fully achieve the cell-killing effects (ADCC and ADCP) of antibody therapeutics.
This technology is designed to bind to Fc alpha receptors on neutrophils, which constitute the highest proportion of immune cells in mammals. It overcomes the limitations of conventional IgA by enhancing antibody-dependent cell-mediated cytotoxicity (ADCC) and phagocytosis (ADCP), and can be broadly applied as various Fc-fusion protein therapeutics.
