Abstract: Disclosed is a system and method for supporting automated self-experimentation based on lifelog data for health behavior change. The system includes a data collection unit configured to collect data related to a user from a plurality of smart terminals and preprocess the data as variables that represent a lifelog of the user; a causal inference unit configured to establish a causal relationship hypothesis between the variables of the user and infer a causal relationship between the variables collected from the user using a statistical analysis method; a variable recommendation unit configured to recommend a variable for verifying the causal relationship through self-experimentation for the user based on an inference result acquired from the causal inference unit and an interaction of the user with the system; and a self-experimentation planning unit configured to plan and conduct an experiment to verify the causal relationship through the self-experimentation for the user.

Abstract: According to an embodiment of the inventive concept, a magnetic memory device includes a substrate on which a transistor controlled by a word line is disposed, a spin detection layer disposed on the substrate, and a magnon spin valve disposed on the spin detection layer. Here, the magnon spin valve includes a free layer disposed on the spin detection layer, a reference layer disposed on the free layer, and a spacer disposed between the free layer and the reference layer. Also, one edge of the spin detection layer is connected to a source/drain region of the transistor, the other edge of the spin detection layer is connected to a source line, and the magnon spin valve is disposed on a portion between the one edge and the other edge of the spin detection layer. The spin detection layer includes a topological material or a weyl semimetal. Each of the reference layer and the free layer includes a ferromagnetic insulator.
