Abstract: An integrated sieve device for particle size screening of a soil sample is provided, the device comprising: a particle size screening unit having at least one sieve and configured to screen the soil sample by particle sizes and to drop the soil sample; a body housing in a cylindrical shape, wherein a part of a lateral surface of the body housing is open, wherein the particle size screening unit is detachably coupled to an inner lateral surface of the body housing; a sample reception unit mounted at a lower portion of the particle size screening unit coupled to the body housing and configured to collect soil and water discharged below the particle size screening unit by being screened by the sieve; and a water supply unit mounted at an inlet formed on an upper end of the body housing and configured to supply water into the particle size screening unit.

Abstract: The purpose of the present disclosure is to provide a system and a method for identifying lithofacies classification information of rare earths in deep-sea sediments using the natural gamma ray data, as well as for estimating rare earth resource quantities in the deep-sea sediments. An aspect of the present disclosure provides a system for estimating rare earth resource quantities in deep-sea sediments using gamma rays, the system comprising: a data collecting unit configured to collect gamma ray data about deep-sea sediments; a data processing unit configured to normalize and process the gamma ray data collected by the data collecting unit; and an estimation modeling unit configured to generate a model for estimating a rare earth lithofacies classification information and the rare earth resource quantities using a linear regression based on the gamma ray data normalized by the data processing unit.

Abstract: Compositions containing extracellular vesicles (EVs) derived from a Faecalibacterium sp. strain are disclosed. The compositions can be used to prevent and/or treat cancer and/or ameliorate symptoms of cancer, and can be pharmaceutical composition, food stuffs, or dietary supplements. The compositions may contain a pharmaceutically acceptable carrier or excipient. The compositions exhibit an excellent effect on the prevention or treatment of cancer, or ameliorating symptoms of cancer.
