Abstract: The present disclosure relates to a cell culture medium composition and a preparation method therefor. By replacing an animal serum with a Spirulina hydrolysate, cell growth can be induced and cell proliferation can be promoted to a level greater than or equal to that of a medium containing an animal serum, while significantly reducing the added amount of animal serum.

Abstract: The present disclosure provides a resource-circulation-type and eco-friendly livestock manure treatment method, and a system for producing algal biomass used therein, the method being capable of: preventing water pollution while allowing livestock liquid fertilizer to be treated on the basis of a biological process; producing algal biomass; and supplying the produced algal biomass to livestock feed and farms.

Abstract: The present invention relates to an integrated connector and a heat exchanger including the same, in which a connector main body is formed by pressing one pipe, a cap is press-fitted into the connector main body, such that the integrated connector is formed so that an interior of the connector main body is blocked by the cap. Therefore, the number of components used to manufacture a connector, which connects and securely couples a header tank and a gas-liquid separator, may be reduced, the integrated connector may be easily manufactured, and a brazing defect may be reduced at portions where the integrated connector is joined to the header tank and the gas-liquid separator of the heat exchanger.

Abstract: The disclosure relates to a sensor network, machine type communication (MTC), machine-to-machine (M2M) communication, and technology for internet of things (IoT). A method of a server is provided. The method includes determining a target temperature range to be applied to a first zone; predicting an indoor temperature for each of a plurality of zones included in a second zone in which the first zone is included; predicting efficiency of at least one first outdoor unit connected to first indoor units installed at the second zone; and controlling operations of the first indoor units based on the target temperature range, the indoor temperature for each of the plurality of zones, and the efficiency of at least one first outdoor unit.
