Seoul National University is a national research university founded in 1946, located in Seoul, the capital of Korea. It is widely considered to be the most prestigious university in the country.The university comprises sixteen colleges and six professional schools, and a student body of about 28,000. It has two campuses in Seoul: the main campus in Gwanak and the medical campus in Jongno. According to data compiled by KEDI, the university spends more on its students per capita than any other university in the country that enrolls at least 10,000.The university holds a memorandum of understanding with over 700 academic institutions in 40 countries, the World Bank, and the country's first ever general academic exchange program with the University of Pennsylvania. The Graduate School of Business offers dual master's degrees with Duke University, ESSEC Business School, and the Peking University, double-degrees at the MIT Sloan School of Management and Yale School of Management, and MBA-, MS-, and PhD-candidate exchange programs with universities in ten countries on four continents. The university's international faculty headcount is 242 or 4% of the total. Nobel laureate Paul Crutzen and Fields Medal recipient Hironaka Heisuke are on the faculty roster. Wikipedia.

An apparatus and method for diagnosing rotor shaft are disclosed herein. The apparatus for diagnosing a rotor shaft that is installed in a bearing so that the rotor shaft is rotated around an axis of rotation includes a measurement unit, a calculation unit, an image generation unit, and a diagnosis unit. The measurement unit measures first vibration signals at two points of the rotor shaft located on a surface perpendicular to the axis of rotation. The calculation unit generates second vibration signals, which are vibration signals at points located in a plane identical to the plane of the two points of the rotor shaft at which the first vibration signals are measured, based on the first vibration signals. The image generation unit generates an image based on the second vibration signals. The diagnosis unit diagnoses the rotor shaft based on the generated image.

The present invention relates to a HEA foam prepared by selective dissolution of a second phase within a two-phase separating alloy comprising the HEA and a manufacturing method thereof. The manufacturing method of the HEA foam of the present invention has the effect of preparing a novel HEA foam, which was not available in the past, by leaving only a first phase after manufacturing a two-phase separating alloy comprising a first phase by HEA, wherein at least 3 metal elements act as a common solvent. Furthermore, the HEA foam of the present invention has a structure, wherein pores are distributed inside the HEA, in which at least 3 metal elements act as a common solvent. By adding a functional characteristic of low heat conductivity, etc., to the existing high strength characteristic of HEA, the HEA foam of the present invention can exhibit a complex effect by the combination of the two particular effects, thereby being capable of exhibiting excellent physical characteristics.
