Abstract: Disclosed is a genome reconstruction method using whole genome data. According to the present invention, the genome reconstruction method reduces detection errors by converting a nucleotide sequence having a structural variation into a graph form, and then reconstructing the graph so that the structural variation and the copy number variation have consistent values. Thereafter, the genome arrangement form was restored by constructing a haplotype graph using heterozygous single nucleotide polymorphism information and then finding an Eulerian path with a minimum entropy value.

Abstract: The present invention relates to a multi-microorganism detection system, and more particularly, to a multi-microorganism detection system using a dielectrophoresis force. Provided is a rapid and accurate multi-microorganism detection system. Microorganisms are concentrated at a high throughput using DEP after synthesizing the microorganisms and fluorescent magnetic particles, and when a complex in which the fluorescent magnetic particles are bound to the microorganisms passes through a detection unit by moving only the microorganisms to the detection unit after separating the magnetic particles from the complex (i.e., the microorganisms to which the magnetic particles are bound) using a DEP force, a fluorescence signal of a specific wavelength band is generated according to the type of the fluorescent magnetic particle and the concentration of the microorganisms according to the type of microorganism is measured by measuring and analyzing the fluorescence signal.
