Abstract: Provided are a novel BBD29_RS02010 variant polypeptide; a polynucleotide encoding the variant polypeptide; a microorganism comprising any one or more of the variant polypeptide, the polynucleotide encoding the variant polypeptide, and a vector comprising the polynucleotide; and a method of producing L-arginine, the method comprising the step of culturing the microorganism in a medium.

Abstract: An electrolyte for a lithium secondary battery including a wettability-improving additive having a trifluoromethylsulfonyl group. The electrolyte has reduced surface tension to improve the wettability of an electrode assembly with the electrolyte. Therefore, it is possible to ensure high electrolyte wettability even when the electrolyte includes a high-boiling point solvent or a high concentration of lithium salt.

Abstract: Provided are a microorganism in which activity of a GNAT family N-acetyltransferase protein is weakened; a method for producing O-acetyl homoserine and L-methionine using the same; a composition for producing O-acetyl homoserine, the composition including the microorganism; and use of the microorganism for producing O-acetyl homoserine or L-methionine.

Abstract: Provided are a microorganism in which activity of an SIRT-type deacetylase protein is weakened; a method for producing O-acetyl homoserine and L-methionine using the same; a composition for producing O-acetyl homoserine, the composition including the microorganism; and use of the microorganism for producing O-acetyl homoserine or L-methionine.

Abstract: The present invention relates to a character arrangement method and a character input method in an electronic device. A telephone-style keypad is assigned symbolic word representations to provide a heuristic and intuitive text input interface to a user. The symbolic word representations on at least some keys on the keypad can create multiple numbers of same alphabets, which can be utilized for easier text entry of frequently-used alphabets. Leftover alphabets which did not get inscribed by the symbolic word representations on some of the keys are grouped together and assigned to leftover keys.

Abstract: Disclosed herein, a new concept of numeral created from alphabet is able to apply in education, telecommunication, computer and toy industry. For the sake of applicability, the present invention provides substitution methods where alphabet is replaced to the corresponding arabic numeral by similarity in shape, similar pronunciation with numbers, similarity in Roman and Chinese. In education, alphabetic language (English, French, Spanish) learners can calculate words and sentences in mathematics (abacus calculation, mental arithmetic, calculation), and learn words and sentences of languages in detail. Math (abacus calculation, mental arithmetic, calculation) learners can study alphabetic languages (English, French, Spanish) not in a tedious repetition of calculation but in a mathematical learning process.
