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: Disclosed is a data collection apparatus for sea creatures including a main body, an antenna, a battery case and a separation unit. The main body includes a sensor assembly configured to collect information about surroundings of a target creature to be recorded, and a battery coupler formed at one side of the main body. The antenna protrudes in one direction from the main body so as to send data to outside. The battery case has a male connector configured such that at least a part thereof is accommodated in the battery coupler so as to be rotatably coupled thereto, and a battery installed in the battery case so as to supply electrical energy to the main body. The separation unit is detachably coupled to the battery case, and is fixed to the target creature to be recorded.

Abstract: Proposed is a complex system of offshore wind power generation, seawater desalination, and water electrolysis. The system may include a wind power generator which generates electric power in such a manner that blades are rotated by wind power. The wind power generator may include a cooler for preventing a overheating phenomenon caused by electric power generation. The system may also include a seawater desalination apparatus which desalinates seawater by using hot water discharged after heat exchange through the cooler. The system may further include a water electrolysis apparatus which receives fresh water produced by the desalination apparatus and a heat source discharged therefrom to use the fresh water and heat source for producing hydrogen. A part of a heat source discharged from the water electrolysis apparatus after the production of hydrogen may be heat-exchanged with the cooler, and heat-exchanged with the heat source discharged from the desalination apparatus.

Abstract: Proposed is a system and method for estimating a drift path of a marine floating body for more accurately estimating a path with a relatively simple configuration and at a relatively low cost. The system and method may achieve a quick and accurate search and contribute to minimizing damage because the system and method can consider both left drift and right drift with respect to a wind direction. The system and method may simulate drift (Leeway) of a marine floating body with respect wind in consideration of both of a Downwind Component of Leeway (DWL) and a Crosswind Component of Leeway (CWL), for example, using Monte Carlo technique, and by creating signs (+/−) by applying a uniform random number to the CWL.
