Abstract: A junction passage control system based on a location of an OHT using a power line communication, includes: an OHT controller mounted on an OHT which moves along tracks; and a central controller that is installed in a junction section of the tracks and controls junction passing of a plurality of OHTs, wherein power lines are laid on the tracks in a zone from a start point of the junction section to an end point of the junction section, and the central controller and the OHT controller transmit and receive data for a junction passage control through power line communication to and from each other.

Abstract: The present invention relates to a method of diagnosing ovarian cancer through microbial metagenomic analysis, and more particularly to a method of diagnosing ovarian cancer by analyzing an increase or decrease in content of specific bacteria or archaea-derived extracellular vesicles through metagenomic analysis using a subject-derived sample. Extracellular vesicles secreted from microorganisms existing in the environment are absorbed into the human body, and thus may directly affect the occurrence of cancer, and it is difficult to diagnose ovarian cancer early before symptoms thereof so that efficient treatment thereof is difficult.
