Abstract: The present disclosure relates to a device and method for forming skyrmion in a magnetic thin film. A skyrmion forming method comprises aligning the surface of the magnetic thin film and a horizontal magnetic field to be applied to the magnetic thin film and applying the horizontal magnetic field and a vertical magnetic field to the magnetic thin film. Accordingly, it is possible to form the bubble skyrmion easily even in the case of a wide width of a stripe formed on the magnetic thin film.

Abstract: The present disclosure is directed to a system and a method for compensating non-linear response characteristics in measuring the shape of an object using phase-shifting deflectomerty. More particularly, the present disclosure is directed to a method for compensating non-linear response characteristics in phase-shifting deflectometry including steps of: generating a pattern by a pattern generating portion and projecting the same to a measurement object; obtaining an image of a deformed pattern reflected from the measurement object by a detector; linearizing non-linear responses on the basis of a look up table considering non-linear response characteristics of the pattern generating portion and the detector by a compensation means; and compensating phase-shifting amounts generated due to non-linear response characteristics by the compensation means.

Abstract: The present invention relates to a system and a method for determining a stroke based on a voice analysis. According to the present invention, voice data of subjects are collected to extract and analyze voice onset times to determine stroke patients based on voices. The system for determining a stroke generates and collects voice data from test subjects reading a predetermined word that includes a plosive sound. The system for determining a stroke extracts and calculates voice onset times from the voice data to calculate probability parameters for the voice onset times of each of a normal group and a stroke patient group. The system for determining a stroke uses a set of probability parameters to determine an integration section, and calculates probabilities of being in the normal group and the stroke patient group. The system for determining a stroke applies the calculated probabilities to the Bayes theorem to determine whether the subjects are stroke patients.

Abstract: Provided is a method of preparing Raman-active nanoparticles, which includes a) preparing a metal nanocore having a nano-star shape from a first reaction solution in which a first metal precursor is mixed with a buffer solution; b) fixing a Raman reporter in the metal nanocore; and c) forming a metal shell, which surrounds the nanocore in which the Raman reporter is fixed, from a second reaction solution in which a second metal precursor is mixed with the nanocore in which the Raman reporter is fixed. The Raman reporter has a binding affinity for each of a first metal of the metal nanocore and a second metal of the metal shell.

Abstract: A method is disclosed for increasing an intensity of a signal detected in a spectroscopy device using a vapor cell and a spectroscopy device using the same. An operation method of the spectroscopy device may include: causing a first light for exciting an atom trapped in a vapor cell in a first hyperfine ground state to a first excited state to be incident on the vapor cell; causing a second light for exciting an atom trapped in the vapor cell in a second hyperfine ground state to a second excited state to be incident on the vapor cell; causing a third light for exciting the atom in the second excited state to a third excited state to be incident on the vapor cell; and detecting fluorescence which is emitted while the atom in the third excited state returns to the ground state.
