Abstract: A system evaluates residential satisfaction of residents living in a building, based on personal tendencies of the residents and sensing data collected through sensors in the building. The system may include a server that evaluates the residential satisfaction of the residents by analyzing a correlation between the sensing data and residential satisfaction information obtained from the survey conducted through a communication manner including the user terminals. The server may control an air conditioning system in the building of a control target by predicting a feature-based preferred section of the users through random forest model learning.

Abstract: A body temperature estimation system and method based on a one-channel temperature sensor are proposed for estimating the body temperature of a target person considering a change in the space temperature or a change in the skin temperature according to a change in the space temperature when continuously measuring the body temperature. The body temperature estimation system may include a temperature measurement unit and a body temperature estimation unit. The temperature measurement unit is attached to a skin of the target person and measures a skin temperature at regular intervals. The body temperature estimation unit estimates a current body temperature, based on an average body temperature measured at the regular intervals and the skin temperature received from the temperature measurement unit, by reflecting the average body temperature, the skin temperature, a difference value (h) of the skin temperature, and a change amount (h?) of the skin temperature difference value.

Abstract: A system and method are proposed for estimating the body temperature of a target person in consideration of movements of the target person and changes in the external temperature due to a sudden change in the space temperature when continuously measuring the body temperature. The body temperature estimation system includes a temperature measurement unit, a movement measurement unit, and a body temperature estimation unit. The temperature measurement unit is attached to a skin of the target person and measures a skin temperature and an external temperature. The movement measurement unit measures movements of the target person. The body temperature estimation unit estimates the body temperature based on a correlation between the skin temperature and the external temperature, and monitors a change in the external temperature per monitoring time.

Abstract: A system evaluates residential satisfaction of residents living in a building, based on preferred sections of the residents predicted using personal tendencies of the residents and sensing data collected through sensors in the building. The system may include a server that evaluates the residential satisfaction of the residents by analyzing a correlation between the sensing data and residential satisfaction information obtained from the survey conducted through a communication manner including the user terminals, and controls an air conditioning system in the building of a control target by predicting a feature-based preferred section of the users through random forest model learning.
