Abstract:
Provided is a method of producing D-psicose using a D-psicose epimerase derived from Agrobacterium tumefaciens. Provided are a protein having an amino acid sequence of SEQ ID NO:1 and having a psicose 3-epimerase activity, a gene encoding the protein, a recombinant expression vector containing the gene, and a method of producing D-psicose by reacting the protein produced on a mass scale with D-fructose. The method of producing D-psicose is an environmentally friendly method using a new enzyme, in which an inexpensive substrate is used, and the activity of the enzyme can be retained for a prolonged time period. Thus, the method can be efficiently used for the mass production of D-psicose.

Abstract:
The computer manufacturing system includes an assembly unit wherein various assembly parts are assembled into a main chassis according to a process order to complete the assembly of a computer body, an aging and test unit for testing and checking the performance of the computer body transferred from the assembly unit, and a package unit for packaging the computer body transferred from the aging and test unit. The assembly unit, the aging and test unit, and the package unit are sequentially aligned in accordance with process sequences. The assembly unit and the package unit are aligned to the opposite facing each other while the aging and test unit is located between the assembly unit and the package unit.
Abstract:
Provided are methods of forming semiconductor devices. A method may include preparing a semiconductor substrate including a first region and a second region adjacent the first region. The method may also include forming sacrificial pattern covering the second region and exposing the first region. The method may further include forming a capping layer including a faceted sidewall on the first region using selective epitaxial growth (SEG). The faceted sidewall may be separate from the sacrificial pattern. The sacrificial pattern may be removed. Impurity ions may be implanted into the semiconductor substrate.
