Abstract: A physiological state determination system includes a CPU and a camera. The camera acquires a photographic image data of a time-series change in facial data of a subject to which brain function activation information that activates human brain function was provided. The CPU determines a mental or physical physiological state of the subject based on facial change information corresponding to the photographic image data.

Abstract: A brain activity estimation device includes a brain activity estimation portion. The brain activity estimation portion includes a blood-circulation-amount calculating unit and an estimation unit. The blood-circulation-amount calculating unit is configured to calculate time-series blood-circulation-amount data on a facial surface of a human based on RGB data of photographed image data on the facial surface acquired in time series. The RGB data is obtained by conducting RGB processing on the photographed image data. The RGB processing includes decomposing the photographed image data into three color components composed of an R component, a G component and a B component. The estimation unit is configured to estimate brain activity of the human based on a plurality of decomposition components obtained by decomposing the blood-circulation-amount data by singular value decomposition, principal component analysis, or independent component analysis.

Abstract: A brain activity estimation device includes a facial skin temperature acquisition element and a brain activity estimation element. The acquisition element detects a skin temperature of at least part of a human face, and acquires facial skin temperature data including detected temperature data and location data of a detection region in a time series manner. The estimation element estimates human brain activity based on the facial skin temperature data acquired. The estimation element decomposes the facial skin temperature data into a plurality of components, extracts a component as a determination component, and determines whether the determination component is related to the human brain activity based on a presence or absence of a temperature change in a prescribed region of the human face.

Abstract: Disclosed herein is a method for determining the drug sensitivity of a microbe which comprises pouring a microbial suspension into each of the compartments or wells at a position which is in the vicinity of an electrode for measuring dissolved oxygen concentration, measuring current from each electrode at a second time interval for a third time period, each time is obtained based upon each of the measured currents at which the maximum current is obtained, obtaining each current value within a fourth time period which starts from the time at which the maximum current is obtained, detecting drug sensitivity based upon the variation condition of each current value during the fourth time period. The method allows rapid drug susceptibility measurements.

Abstract: A method and apparatus wherein measurement current values output from a first oxygen sensor and a second oxygen sensor are time sequentially measured. Each moving average value is calculated from each sequential measurement current value. Each time differential value is calculated from the pair of each calculated moving average values, by least squares approximation. Then, drug susceptibility is measured based upon each calculated time differential value, so that drug the susceptibility measurement is performed quickly or accurately.

Abstract: A sanitary measurement system is configured and arranged to reduce a load relating to sanitary measurement in a plurality of food factories. The sanitary measurement system registers a plurality of food factories, manages and effectively utilizes sanitary information obtained from the food factories. The sanitary measurement system includes a sanitary information managing server and a measuring device. The measuring device performs sanitary inspection in each food factory, and sends data (sanitary information) formed of a result of the inspection to the sanitary information managing server.
