The ultra-low-field nuclear-magnetic-resonance device includes magnetic shielding room; a high-sensitivity magnetic field sensor disposed adjacent to a measurement target disposed inside the magnetic shielding room; and a bias magnetic field generating coil for providing an external measurement bias magnetic field, corresponding to a proton magnetic resonance frequency (nuclear magnetic resonance frequency) corresponding to a frequency of periodic myocardial activity of a lesion desired to be measured, to the measurement target. The high-sensitivity magnetic field sensor measures a magnetic resonance signal generated from the measurement target.

Abstract: A method of controlling a magnetization state using an imprinting technique may be provided. The method may include moving first and second magnetic structures, which have different magnetization states, toward each other and changing a magnetization state of the first or second magnetic structure, when a distance between the first and second magnetic structures is reduced. A magnetic field, which is produced by a magnetization state of one of the first and second magnetic structures, may be used to align a magnetization state of the other, when the magnetization state of the first or second magnetic structure is changed.

Abstract: A vacuum sample chamber for a particle and optical device includes on one surface thereof, an aperture through which a particle beam to be focused along an optical axis of particles such as electrons, ions and neutral particles is incident; and on the opposite surface thereof, a detachable sample holder through which light penetrates, thereby enabling a sample to be observed and analyzed by means of the particle beam and light. A sample chamber is capable of reducing observation time by maintaining a vacuum therein even when a sample is put into or taken out from a sample chamber of an electron microscope or focused ion beam observation equipment, and capable of obtaining an optical image on the outside thereof without inserting a light source or an optical barrel into the sample chamber. A light-electron fusion microscope comprising the sample chamber.

Abstract: An ultraviolet index measuring method and apparatus includes preparing a first photosensor having spectral response only in a first section of a wavelength between 250 nm and 298 nm, a second photosensor having spectral response only in a second section of a wavelength between 298 nm and 328 nm, and a third photosensor having spectral response only in a third section of a wavelength between 328 nm and 400 nm. An output signal of the first photosensor, an output signal of the second photosensor, and an output signal of the third photosensor are calibrated using spectral irradiance of reference solar light. First photocurrent of the first photosensor, second photocurrent of the second photosensor, and third photocurrent of the third photosensor are measured under a measurement environment. An ultraviolet index is calculated using the first photocurrent, the second photocurrent, and the third photocurrent under the measurement environment.

Abstract: The present disclosure relates to a temperature controllable anechoic sound absorber using two different kinds of scattering particles and a method for manufacturing the same. More specifically, a temperature rise controllable anechoic sound absorber using two different kinds of scattering particles, which absorbs a sound wave which is transmitted through a medium, includes a composite material which induces a scattering process of the sound wave and has a first scattering particle and a second scattering particle; and a base material which fills a base of the absorber during the scattering process of the sound wave. Herein, volume content ratios of the base material, the first scattering particle, and the second scattering particles are adjusted so that a heat capacity of the absorber is within a set heat capacity range.
