The composition comprising extract or organic solvent fraction of oak vinegar as an effective ingredient has superior insect-repellent or insecticidal activities against lasioderma serricorne, which damages tobacco, grains, paper or clothes, reticulitermes speratus kyushuensis Morimoto, which chews the woods from within, or sitophilus oryzae, which has strong tolerance to insecticides, and therefore, can be applied efficaciously as an insect-repellent or insecticidal composition to conserve wooden furniture, an old house, or many organic cultural heritages.

Abstract: Disclosed herein is an insect proof or insecticidal composition for the conservation of cultural properties against termites, comprising an extract of Asarum sieboldii as an active ingredient. Based on a methanol extract of Asarum sieboldii or a hexane fraction from the methanol extract, the composition is environmentally friendly and non-toxic to humans and animals. Also, because of its excellent insecticidal activity against termites, the composition can be used to protect wooden structures and cultural properties from termite damage, which is a great threat to the life of wooden structures and cultural properties, without toxicity to humans and animals.

Abstract: An insect-repellent and insecticidal composition comprising extract or fraction of phellodendron amurense as an active ingredient is provided. The extract of phellodendron amurense, or the hexane (Hex) extract, methylene chloride (MC) fraction, or ethyl acetate (EtOAc) fraction provides insect-repellent or insecticidal activities against lasioderma serricorne which harms tobacco, crops, paper, clothes or wood, or against sitophilus oryzae which has strong tolerance to insecticide, and thus can be effectively applied as an insect-repellent or insecticidal composition to conserve wooden furniture, an old house, or many organic cultural heritages.

Abstract: The present invention relates to a pharmaceutical composition, including inhibitors for expression or activity of TIP41 protein, for prevention and treatment of cancer. When the liver cancer cell lines, showing resistance to TRAIL, are treated with TIP41 siRNA and TRAIL, apoptosis is induced in cancer cell. The same effect is found in cases of lung cancer and colon cancer with resistance against TRAIL. Moreover, this induction of apoptosis by TIP41 siRNA and TRAIL was confirmed in tumor xenograft, which was injected with Huh7 liver cancer cells and then was subjected to TIP41 siRNA transfection and TRAIL treatment. In addition, it was confirmed through animal experiments in which the tumor size has reduced and apoptosis was induced by treatment with TIP41 siRNA and TRAIL. Of note, MKK7/JNK pathway was confirmed to mediate the apoptosis induced by the application of TIP41 siRNA and TRAIL. The apoptosis were verified to be caused by the activation of MKK7/JNK signaling pathway.

Abstract: A sound zoom method, medium, and apparatus generating a signal in which a target sound is removed from sound signals input to a microphone-array by adjusting a null width that restricts a directivity sensitivity of the microphone array, and extracting a signal corresponding to the target sound from the sound signals by using the generated signal. Thus, a sound located at a predetermined position away from the microphone array can be selectively obtained so that a target sound is efficiently obtained.

ZNF312b gene expression is specifically increased in stomach cancer. And the over-expression or the under-expression of the gene affects activation or inhibition of cell proliferation and tumor formation of a stomach cancer cell line and cell proliferation signal transduction system as well to induce stomach cancer at last. Therefore, ZNF312b marker gene can be effectively used for diagnosis of stomach cancer, construction of a stomach cancer animal model, prevention and treatment of stomach cancer and development of a stomach cancer specific anticancer agent.

Abstract: A method, medium, and apparatus for extracting a target sound from mixed sound. The method includes receiving a mixed signal through a microphone array, generating a first signal whose directivity is emphasized toward a target sound source and a second signal whose directivity toward the target sound source is suppressed based on the mixed signal, and extracting a target sound signal from the first signal by masking an interference sound signal, which is contained in the first signal, based on a ratio of the first signal to the second signal. Therefore, a target sound signal can be clearly separated from a mixed sound signal which contains a plurality of sound signals and is input to a microphone array.
