The present disclosure relates to a novel method of preparing a vanadosilicate molecular sieve, and a vanadosilicate molecular sieve and their derivatives prepared by the same method. The preparing method of a vanadosilicate molecular sieve includes forming a vanadosilicate molecular sieve by a hydrothermal reaction of a reaction mixture containing a silicon source, a base, a V-containing compound as a vanadium source, a reducing agent, a salt and water.

The present invention relates to a biomarker for the identification of exposure to lower aliphatic saturated aldehydes by using micro RNA and a method for the identification of exposure to lower aliphatic saturated aldehydes using the same. In this invention, the micro RNA at least 1.5 fold up-regulated by exposure to lower aliphatic saturated aldehydes and the micro RNA up to 0.66 fold down-regulated by the same were selected. These two micro RNAs can be effectively used as the biomarker for the monitoring of lower aliphatic saturated aldehydes and for the risk assessment thereby and at the same time as a tool to investigate the mechanism of toxicity caused by such lower aliphatic saturated aldehydes.

The present invention provides a chiral inorganic-organic composite porous material in which cationic chiral organic molecules are present as charge-balancing cations in a porous material containing charge-balancing cations, as well as a method for preparing the same by an ion exchange process. The chiral inorganic-organic composite porous material according to the present invention is excellent in stability, selectivity and durability, and thus, will be useful as a chiral-selective catalyst or a material of separating an isomeric mixture.
