Abstract: Disclosed is a composite thermal management system for an electric ship capable of maximizing the performance of a battery through efficient thermal management of a cabin, a battery, and a motor, and selectively switching between cooling and heating by a heat pump control method. The composite thermal management system for an electric ship selectively cools or heats a cabin, a battery, and a motor equipped in the electric ship, and includes a first heating and cooling unit that selectively switches a circulation cycle of a refrigerant according to a cooling or heating mode to cool or heat an inside of the cabin and a second heating and cooling unit that cools and heats the battery and the motor using coolant heat-exchanged with the refrigerant.

Abstract: Disclosed is a thermal management system for an energy storage system capable of efficiently cooling a battery and a power conversion system with different management temperatures by selectively switching a cooling method according to an outdoor temperature of the energy storage system. A thermal management system for an energy storage system cools a battery and a power conversion system arranged inside the energy storage system by selectively switching a cooling method according to an outdoor temperature of the energy storage system, and includes a first cooling unit that cools the battery and the power conversion system with a first coolant cooled using outside air, and a second cooling unit that cools the battery with a second coolant cooled using a refrigerant.

Abstract: Provided is a composition for preventing or treating erectile dysfunction including angiopoietin-4 protein as an active ingredient. Angiopoietin-4 protein increases an endothelial cell-specific protein level to induce regeneration of penile vascular endothelial cells, thereby increasing intracavernous pressure. Thus, angiopoietin-4 protein may be efficiently applied to prevention or treatment of erectile dysfunction.
