Abstract: The present invention provides an infection prevention device and an infection prevention method including a light source 11 for radiating light in specific wavelength range, and a beam-firming optical element 12 for forming the light radiated from the light source 11 on a radiant film 20 having a predetermined width, wherein pathogenic microorganism which levitates together with airborne droplets or particles or which levitates alone is inactivated or killed by the radiant film 20 formed in air, or moisture of the airborne droplets or the particles is evaporated. According to this, pathogenic microorganism which levitates in air can be inactivated or killed in air.

Abstract: One aspect example is a system for photogrammetry of a building. A memory stores design data and physical material data. The design data includes virtual material information on attributes for each of virtual materials of a virtual building. The physical material data is on the attributes for each of physical materials and generated based on measured data acquired from a physical building constructed on the basis of the design data. A material associating processor is configured to generate pairs of virtual and physical materials by determining an association between the virtual materials and the physical materials based on the virtual material information and the physical material data. An attribute associating processor is configured to determine an association between the virtual material information and the physical material data in accordance with the attributes for each of the pairs.

Abstract: An explicit knowledge conversion assistance apparatus 100 includes: a table acquisition unit 10 that acquires a table in which, for each agricultural task for a specific crop, an influence degree indicating influence that the agricultural task has on an outcome, a type of skill required for the agricultural task, and a level of a worker required for the agricultural task are defined by numerical values; an evaluation value calculation unit 20 that, for each agricultural task, calculates an evaluation value based on the values for the influence degree, the type of skill, and the level, using the table; and a priority rank setting unit 30 that sets a priority rank for each agricultural task based on the calculated evaluation value.

Abstract: A skill transfer facilitating apparatus 10 is an apparatus for facilitating skill transfer, and includes a data accumulation unit 11 that accumulates data regarding tasks that are executed using skills that are to be transferred; and a rule creation unit 12 that extracts, from the data that is accumulated, task names, task execution results, and task reasons as information, executes, for each combination of a task name and a task execution result thus extracted, statistical processing with respect to each corresponding task reason, and then creates, for each task, a rule that serves as a condition for executing the task or a condition for not executing the task, based on the result of statistical processing.

Abstract: A noninvasive method for measuring biological materials which is configured to enable an immediate diagnosis is used in an analytical absorption spectroscopy apparatus including a broadly tunable infrared laser oscillation device, a photodetection device, and an analysis device. The method applies an infrared ray to an analyte organism while tuning the wavelength from the laser oscillation device with or without the ray going through a nonlinear optical device. The photodetection device detects a reflected beam, a transmitted beam, or a scattering beam from the organism or ultrasound generated within the organism by using the detection device. The analysis device analyzes a signal input by the photodetection device.

Abstract: In a laser scanning method for measuring in vivo substances, wavelength of the anti-Stokes line is made greater than wavelength absorption band of the specific substance, the wavelength of the probe light is shifted from the wavelength of the anti-Stokes line by a shift amount of Raman scattering of the specific substance, and the wavelength of the Stokes light is shifted from the wavelength of the probe light by the shift amount of the Raman scattering of the specific substance. According to this, density (concentration and distribution) of lutein in an eye fundus is measured quantitatively and non-invasively from a signal strength level of the anti-Stokes line.
