Abstract: A bioreactor for suspended cells is provided. The bioreactor for suspended cells comprises: a housing which is formed in the shape of a container having a culture space with a predetermined volume, and which comprises pots for seeding; a support assembly comprising a plurality of supports arranged at intervals in multiple stages in one direction of the housing; at least one gas inlet penetrating the housing by a predetermined area; and a porous member for covering the gas inlet, wherein the culture space comprises a medium storage space filled with a predetermined amount of a medium so that all the plurality of supports are submerged therein, and the medium storage space can comprise a plurality of cell growth spaces divided through the plurality of supports arranged at intervals in multiple stages.

Abstract: Disclosed is an apparatus for determining an energy cost applied to an energy sharing transaction system which performs a secondary energy sharing transaction between a seller and a buyer having an energy production facility which is operated by using primary energy as a power source to produce secondary energy.

Abstract: A bioreactor for suspension cells is provided. The bioreactor for suspension cells may comprise: a frame unit; a driving unit mounted on the frame unit, and a cell culture unit including a housing having an inner space filled with a medium containing suspension cells, and a plurality of supports disposed in multiple stages in the inner space to be spaced at intervals from each other, the cell culture unit having one end axially coupled to the driving unit.

Abstract: A network separation device that can separate an internal network and an external network with little changes in the networks in a video surveillance system providing monitoring picture data through the internal network and the external network. The network separation device receives monitoring picture data from a monitoring camera that acquires a monitoring picture, transmits outbound picture data unidirectionally to an external network client through an external network in response to a request of the external network client, and transmits inbound picture data to an internal network client through an internal network in response to another request from of the internal network client.
