Abstract: Disclosed is a sleep management system including at least one sensor that to detects a biometric signal of a user, at least one electronic device, and a hub device that communicates with the at least one sensor and the at least one electronic device. The hub device identifies, based on the biometric signal of the user, a stage as a sleep preparation stage, a sleeping stage, or an awake stage, and transmits, to the at least one electronic device, a control command to control the at least one electronic device based on the identified stage.

Abstract: Provided is a fluorine-based resin that has liquid-repellency and high solubility in a fluorine-based solvent, and becomes insoluble in the solvent by photocrosslinking at low light exposure intensity. A fluorine-based resin of the present invention includes: a repeating unit that is represented by Formula (1) including a photocrosslinkable group; and a repeating unit that includes a fluorine atom, where R1 represents hydrogen or methyl, L1 represents a single bond or a linking group, A represents a linking group, and R2 through R6 represent one selected from the group consisting of hydrogen, halogen, alkyl, alkyl halide, alkoxy, aryl, aryloxy, cyano, and amino.

Abstract: Provided is a resin which is excellent in terms of solubility in common solvents, crosslinking temperature, time required for crosslinking, solvent resistance (cracking resistance), breakdown voltage, leakage current, solvent wettability, and planarity in cases where the resin is formed into a thin film. A resin which comprises repeating units represented by formula (1) and formula (2), and wherein the repeating unit represented by formula (2) is contained in an amount of 20% by mole or more relative to the total amount of the repeating units represented by formula (1) and formula (2).
