Abstract: The present invention provides a biomarker for identifying the expression of an inflammatory-response-associated gene that specifically causes a change in expression due to exposure to 2-butanone, which is harmful and found in indoor environments, and an identification method using the same, and particularly an inflammatory-response-associated gene, the expression of which is increased or decreased by exposure to 2-butanone in a human bronchial epithelial cell line model (BEAS-2B), and a method of identifying exposure and predicting an inflammatory response using the same. The biomarker of the present invention includes specific genes selected through RNA sequencing, and thus can be useful in monitoring and determining the exposure to 2-butanone in the environment, and can be utilized as a tool predicting the mechanism of inflammatory response and toxicity caused by exposure to 2-butanone.

Abstract: The present invention relates to a functional resin composition comprising a biomass-derived component, and more particularly to a functional resin composition comprising: a biomass-derived component; an aromatic dicarboxylic acid; an alcohol component; a chain extender; and a multifunctional compound. The biomass-derived component is biomass-derived succinic acid alone or a mixture of biomass-derived succinic acid alone and fossil-derived aliphatic dicarboxylic acid. The functional resin composition comprising these components has excellent processability, moldability, tearing strength and tensile strength, and does not easily change over time due to its excellent hydrolysis resistance.

Abstract: Disclosed are a biomarker for identifying specific exposure to ketones, which are one of environmentally harmful substances that may be exposed in the indoor atmosphere environment, and a method for identifying exposure to ketones using the same. More specifically, disclosed are a biomarker composition and a kit for identifying specific exposure to ketones containing genes, the expression of which is increased or decreased specifically in human bronchial epithelial cell lines by exposure to five kinds of ketones including acetone, butanone, pentanone, hexanone and heptanone, and a method for identifying exposure to ketones using the same. Fast-throughput sequencing using a biomarker including a gene showing a changed expression pattern upon exposure to five types of ketones including acetone, butanone, pentanone, hexanone and heptanone is useful for rapidly and accurately monitoring and determining the contamination level of ketones in the environment.

Abstract: A microfluidic device for concentrating or purifying a sample containing cells or viruses including a sample circulating vessel having a constant capacity; a pump connected to the sample circulating vessel and a trapping unit located in the sample circulating vessel. A method of concentration or purifying a sample containing cells or viruses including introducing the sample containing cells or viruses into a sample circulating vessel, circulating the sample within the sample circulating vessel by a pump connected to the sample circulating vessel, capturing the cells or viruses contained in the sample at a specific site inside the sample circulating vessel to concentrate or purify the sample and recovering the concentrated or purified sample from the sample circulating vessel.

Abstract: A method and apparatus for electrically measuring an adverse effect of toxic substances on prokaryotic cells includes measuring a whole intracellular change caused by the presence of toxic substances as a change in an electric signal of cell membranes of the prokaryotic cells. According to the present invention, it is possible to electrically measure the presence of toxicity and the extent of the adverse effect very easily and within a rapid period of time and also to measure the adverse effect of toxic substances regardless of their type. Thus, the method and apparatus of the present invention have wide applicability and can be easily applied to a lab-on-a-chip.

Abstract: A method for transforming and presenting a message and a mobile station using the transformed message is provided. By transforming a received message, such as a voice or character message, into tactilely sensed symbols, the contents of the message can be recognized via touch or sight by a user having a visual and/or auditory disability.

Abstract: A tape substrate including an insulating film, a copper foil pattern formed on the insulating film at one side of the insulating film, and provided with a connecting area where an electronic element is to be mounted, a barrier layer plated on the copper foil pattern at the connecting area, and formed with a plurality of pores, and a tin layer plated on the barrier layer, and alloyed with a portion of the copper foil pattern corresponding to the connecting area, through the pores. A method for fabricating the tape substrate is also disclosed. In accordance with the invention, it is possible to reduce the time taken for the copper foil pattern to come into contact with the electroless tin plating solution used in the tin plating process, thereby preventing the copper component of the copper foil pattern from being eluted. Accordingly, there is no open-circuit fault caused by formation of pores.
