An acetone concentration estimate device acquires a measured acetone concentration measuring acetone excreted from a user, acquires an elapsed time which has elapsed since the user ate a meal, and estimates an acetone concentration, which is a ketone body concentration of when an amount of change in blood sugar level of the user per given unit of time is stable, based on the acquired current measured acetone concentration and on the acquired elapsed time, and outputs information corresponding to the estimated acetone concentration.

A biological gas detection device acquires a reference output value that is an output value outputted from a semiconductor gas sensor in a reference air sample, the semiconductor gas sensor having sensitivity to an interfering gas and a target gas contained in a biological gas, acquires a target gas concentration that is a concentration of the target gas measured based on a first output value, the first output value being outputted from the semiconductor gas sensor during measurement of the biological gas, corrects the target gas concentration based on a second output value and the reference output value, the second output value being outputted from the semiconductor gas sensor in an air sample prior to measurement of the biological gas; and outputs information according to the corrected target gas concentration.

The invention provides a poor physical condition determination device, method, and program enabling simple determination of a physical condition level. A poor physical condition determination deviceacquires a ketone concentration measurement measuring ketone excreted from a user, determines a physical condition level related to the physical condition of the user based on the acquired ketone concentration measurement, and outputs a determination result.

The invention provides a physical change evaluation device, method, and program capable of easily evaluating physical change from the past to the present, and from the present into the future. A physical change evaluation deviceacquires a ketone concentration measurement measuring ketone excreted from a user, acquires physical data relating to the body of the user, evaluates physical change in the user based on the acquired ketone concentration measurement and the physical data, and outputs an evaluation result.

A gas measurement apparatus of the present invention includes a gas sensor and is capable of being in any one of an open state in which the gas sensor is connected to an outside air and a closed state in which the gas sensor is cut off from an outside air. The gas measurement apparatus includes: an acquisition unit; and a determination unit. The acquisition unit acquires a detection value of the gas sensor in the open state and a detection value of the gas sensor in the closed state. The determination unit compares the detection value of the gas sensor acquired in the open state and the detection value of the gas sensor acquired in the closed state to thereby determine the state of the gas sensor.
