A hybrid translation apparatus includes a source language input unit for generalizing an input source language sentence for each node; a statistics-based translation knowledge database(DB) for storing learning data generalized for each node to be acquired; a first translation result generating unit for transforming the source language sentence generalized for each node into a node expression using the statistics-based translation knowledge to generate a first translation result; and a second translation result generating unit for repeatedly performing the generation of a target word for each node on the first translation result using pattern-based knowledge to generate a second translation result as target words for the respective nodes. Further, the hybrid translation apparatus includes a pattern-based translation knowledge DB for using in the pattern-based translation; and a translation result combining unit for combining the first translation result and the second translation result to output a target language sentence.

Disclosed is a method for preparing a lithium-metal composite oxide, the method comprising the steps of: (a) mixing an aqueous solution of one or more transition metal-containing precursor compounds with an alkalifying agent and a lithium precursor compound to precipitate hydroxides of the transition metals; (b) mixing the mixture of step (a) with water under supercritical or subcritical conditions to synthesize a lithium-metal composite oxide, and drying the lithium-metal composite oxide; and (c) subjecting the dried lithium-metal composite oxide either to calcination or to granulation and then calcination. Also disclosed are an electrode comprising the lithium-metal composite oxide, and an electrochemical device comprising the electrode. In the disclosed invention, a lithium-metal composite oxide synthesized based on the prior supercritical hydrothermal synthesis method is subjected either to calcination or to granulation and then calcination. Thus, unlike the prior dry calcination method or wet precipitation method, a uniform solid solution can be formed and the ordering of metals in the composite oxide can be improved. Accordingly, the lithium-metal composite oxide can show crystal stability and excellent electrochemical properties.

This invention is about extracting two signals from the signal in which more than two frequency components are mixed. In detail, this is about extracting low or high frequency component by distinguishing signal distortion using slope tracing wave. This invention applies two slope tracing wave to an arbitrary signal to track signal distortion and extract and remove low frequency component such as the variation of electrocardiogram signal baseline or easily extract or remove 60 Hz interference wave easily introduced to electrocardiogram. In addition, this allows easy detection of a specific waveform such as P wave and T wave from the electrocardiogram diagram by using the difference between the arbitrary signal and two slope tracing wave. The methods of this invention include distinguishing signal distortion, and detecting, extracting, removing the variation of unfavorable baseline using the shape characteristics of the distinguished section, and also detecting, extracting, removing external interference wave such as 60 Hz noise. In addition, the methods of this invention include distinguishing signal distortion and easily detecting P wave and T wave when the baseline is changed using the shape characteristics of the distinguished section.

The present invention relates to liposomes comprising novel peptide antigens which play a role in regulating human immunity against hepatitis B virus, more specifically, to peptide groups corresponding to epitopes of antigens derived from X protein of HBV which induce cytotoxic T lymphocytes against the virus or immunological tolerance to the virus, and pH-sensitive liposomes comprising said peptide groups to induce cellular immunity so that CTLs specific to the virus can be produced. Since peptide antigens derived from X protein such as X3, X4, X5, X6 and X7 activate CTL which can recognize HBV antigens present in human body, and can also be recognized by the CTL, the liposomes can be used for the development of proposed therapeutic agents for the prevention and treatment of HBV-associated diseases.
