Abstract: Disclosed herein are a novel crown ether with bulky and rigid groups and a method for preparing the same. Also provided are a lithium adsorbent comprising the novel crown ether immobilized onto a nanofiber, and a method for preparing the same. The lithium-selective crown ether is synthesized through intermolecular cyclization between a bulky epoxide and a rigid aromatic compound such as 1,2-dihydroxybenzene, and can effectively recover lithium ions. For use as a lithium adsorbent, the novel crown ether with both bulky and rigid subunits is immobilized onto a polymer nanofiber. The crown ether-immobilized polymer nanofibers may be formed into a recyclable membrane.

Abstract: The present invention relates to fusion polynucleotides for biosynthesis of beta-carotene and a method for producing beta-carotene using the same. More particularly, it relates to fusion polynucleotides encoding phytoene synthase, connective sequences of FMDV-derived 2A sequence or internal ribosome entry site (IRES) and carotene desaturase, and a method for producing beta-carotenes using the same. Fusion polynucleotides and the recombinant vector using the same of the present invention have the effect of expression both phytoene synthase gene and carotene desaturase gene stably within cell transformants. Accordingly, fusion polynucleotides of the present invention can be used to regulate the biosynthetic metabolism of plant producing beta-carotene. Furthermore, it can be applied to effectively increase the content of beta-carotene, a useful metabolite.

Abstract: Disclosed are a composition for inhibiting the expression of GA733-2 or for detecting GA733-2, which comprises TREM-2 gene or protein, a transgenic animal containing same, and a method using the same.

Abstract: A wet type scrubber for exhaust gas includes a wet scrubbing chamber which is disposed such that the exhaust gas introduced through an inlet flows horizontally toward an outlet and includes an overflow opening formed at a position in a side surface thereof spaced apart by a certain distance upwardly from the bottom thereof an eliminator which is disposed within the wet scrubbing chamber and installed such that the bottom thereof is positioned below the overflow opening, and includes a plurality of bent blades arranged to form a passage for the exhaust gas; an oil/water separation tank for scrubbing liquid received from the overflow opening by sequentially passing the liquid through a plurality of reservoirs, and a spray nozzle installed to spray the liquid into an inlet-side space of the wet scrubbing chamber.

Abstract: A tile lighting system is provided in which an interior space of a tile is lit by LEDs, such as in a grid or edge-lit formation, and a light diffusing panel is disposed over the interior space. The tile lighting system can be combined with others to tile any surface, such as a floor, ceiling, wall, or building exterior. Lighting control signals can be supplied to generate a wide range of effects on the tile lighting units, including effects coordinated among different tile lighting units. Two- and three-dimensional embodiments are contemplated.

Abstract: A microorganism cotransformed with a gene expressing HIV nucleocapsid protein and a plasmid vector containing HIV ? gene and ?-galactosidase reporter gene, and a method for screening HIV inhibitors employing the transformant. The invented method comprising the steps of culturing the transformant, treating it with putative compounds or compositions of HIV inhibitors, and measuring the degree of change in ?-galactosidase expression in the culture, can be practically applied in screening HIV packaging inhibitors by which the interaction between HIV nucleocapsid and HIV ? sequence is blocked.
