Provided is a skin external preparation for cellulite improvement and a cellulite improvement method that do not require any special equipment and manipulation and are capable of conveniently improving cellulite. The skin external preparation for cellulite improvement containing at least one component (A) is selected from α-glucosyl hesperidin and α-glucosyl naringin. The cellulite improvement method includes a step of externally applying the skin external preparation for cellulite improvement containing at least one component (A) selected from α-glucosyl hesperidin and α-glucosyl naringin to the skin of a target.

An ultrasound diagnostic apparatus (1) includes a frame thinning-out unit (8), a urinary bladder extraction unit (9), a feature quantity calculation unit (10), a candidate frame extraction unit (11), and a urine volume measurement unit (13). The frame thinning-out unit thins out ultrasound images of some frames from ultrasound images of a first frame group to form a second frame group of ultrasound images, the second frame group being constituted by a smaller number of frames than the first frame group of ultrasound images. The urinary bladder extraction unit extracts a urinary bladder region from each ultrasound image. The feature quantity calculation unit calculates a feature quantity of the urinary bladder region. The candidate frame extraction unit extracts, based on the feature quantity, an ultrasound image of at least one candidate frame from the ultrasound images of the second frame group. The urine volume measurement unit analyzes an ultrasound image of a measurement frame selected from the ultrasound image of the at least one candidate frame to measure a urine volume.

A method of spectrometric analysis comprises obtaining one or more sample spectra for an aerosol, smoke or vapour sample. The one or more sample spectra are subjected to pre-processing and then multivariate and/or library based analysis so as to classify the aerosol, smoke or vapour sample. The results of the analysis are used for various surgical or non-surgical applications.
