Abstract:
A method of stabilizing a field emitter includes performing plasma treatment on carbon nanotubes of the field emitter. The plasma treatment evens the surface of the carbon nanotubes, stabilizing the current density of the carbon nanotubes and increasing the durability of the field emitter.
Abstract:
The present disclosure relates to a method for predicting demand using a visual schema of a product, a device therefor, and a computer program therefor. The demand predicting method includes the operations of: creating visual schemas in which attributes of a product are digitized; analyzing the visual schemas and creating visual schema analysis data which are data relating to the attributes of the product; creating prediction data which are data obtained as a result of demand prediction analysis by attributes of the product using the visual schema analysis data; and creating visual narrative data expressing the prediction data into correlation between products or customers, and describing demand prediction.
Abstract:
The present invention relates to a circulator for a cooling mat, whereby water is brought into contact with a frozen refrigerant, cooled thereby, and then circulated through a pipe of the mat, such that a cooling effect can be provided to a user in contact with the mat by using the circulator having a simple structure.
Abstract:
The present invention provides a novel 2-pyridyl substituted imidazole derivative, or a pharmaceutically acceptable salt or solvate thereof, which selectively inhibits the transforming growth factor-β (TGF-β) type I receptor (ALK5) and/or the activin type I receptor (ALK4); a pharmaceutical composition comprising same as an active ingredient; and a use of the 2-pyridyl substituted imidazole derivative for the manufacture of a medicament for preventing or treating a disease mediated by ALK5 and/or ALK4 receptors in a mammal.
Abstract:
A semiconductor device includes a buffer layer on a semiconductor substrate including first and second regions, a first channel layer on the buffer layer of the first region, a second channel layer on the buffer layer of the second region, and a spacer layer between the second channel layer and the buffer layer. The buffer layer, the first and second channel layers, and the spacer layer are formed of semiconductor materials including germanium. A germanium concentration difference between the first and second channel layers is greater than a germanium concentration difference between the buffer layer and the second channel layer. The spacer layer has a germanium concentration gradient.

A semiconductor substrate and a semiconductor device are provided. The semiconductor substrate includes a base substrate, a first silicon germanium layer on the base substrate and a second silicon germanium layer on the first silicon germanium layer. A germanium fraction of the second silicon germanium layer decreases in the direction away from the base substrate, and a germanium fraction of a lowermost part of the second silicon germanium layer is greater than a germanium fraction of an uppermost part of the first silicon germanium layer.
Abstract:
A spacer covering a sidewall of a contact plug includes a relatively more damaged first portion and a relatively less damaged second portion. An interface of the first and second portions of the spacer is spaced apart from a metal silicide layer of the contact plug. Thus reliability of the semiconductor device may be improved. Related fabrication methods are also described.
Abstract:
Provided are picolinamide and pyrimidine-4-carboxamide compounds, a method for preparing the same, a pharmaceutical composition containing the same, and a medical use using the compound as an agent for preventing, regulating, and treating diseases related to regulation of glucocorticoids by using selective inhibitory activity of the compound for an 11β-HSD1 enzyme.

Abstract:
An apparatus and a method for recovery of sulfur hexafluoride is provided. Sulfur hexafluoride (SF6) may be separated with high-concentration and improved recovery ratio through a multi-stage separation and recovery processes using a plurality of separation membrane modules, and as well, SF6 gas may be concentrated to maximize the SF6 recovery ratio before the separation and recovery processes through the separation membrane modules. Furthermore, sulfur dioxide (SO2) and moisture included in the SF6 waste gas may be removed effectively so as to extend the service life of the separation membrane modules.
