Abstract: The present invention relates to a method for preparing a biomaterial having selectively functionalized tyrosine, a biomaterial having selectively functionalized tyrosine, and a pharmaceutical composition containing the same as an active ingredient. The method for preparing a biomaterial to which a compound represented by formula 2 is coupled, of the present invention, allows the compound represented by formula 2 to be selectively coupled, in a high yield in a biomaterial, to tyrosine, which is present on the surface of an aqueous solution such that the coupling thereof to amino acids other than tyrosine does not occur and, when only one tyrosine is present, heterogeneous mixtures are not present and the inherent activity of the biomaterial is maintained, and thus the compound can be effectively used as a pharmaceutical composition containing a biomaterial drug as an active ingredient.

Abstract: In an air conditioner, a drain extraction unit and a refrigerant pipe connecting unit may be disposed in a blocking region in which a discharge port is not provided so that a size of the discharge port may be secured and the discharge port may be uniformly disposed, thereby generating uniform airflow in a room. In a lower housing formed in a circular shape, some of components inside an indoor unit of the air conditioner may be disposed in a protrusion portion that protrudes from the circular housing, thereby facilitating the installation of the air conditioner. A condensate water collecting space disposed outside the housing may be provided in a drain tray, thereby efficiently preventing a leakage due to condensate water generated outside the housing. The housing, the drain tray, and the cover member of the air conditioner may be coupled by a coupling member coupled outside.

Abstract: A water heater includes a tank device including a tank that extends in an up-down direction and stores a fluid therein and a heating device that heats the outside of the tank to heat the fluid in the tank. One direction crossing the up-down direction is referred to as a reference direction, and the heating device includes a compressor that is located in the reference direction with respect to a lower side of the tank and that compresses a refrigerant, a condenser that has an upper end portion connected with the compressor, has a shape surrounding an outer peripheral surface of the tank, and condenses the refrigerant released from the compressor, an expansion valve that is connected with a lower end portion of the condenser and that expands the refrigerant released from the condenser, and an evaporator that heats the refrigerant passing through the expansion valve.

Abstract: The present invention relates to a pharmaceutical composition comprising trimebutine as an active ingredient for prevention or treatment of cancer. Having an excellent effect of selectively inhibiting growth and proliferation of cancer stem cells, the pharmaceutical composition can suppress the recurrence, metastasis, and progression of cancer even when used alone. Thus, the composition can be advantageously used as a pharmaceutical composition for prevention or treatment of cancer or in combination with other agents.

Abstract: Proposed is a solar power leveling system, more particularly, a solar power leveling system via string-based power compensation, wherein outputs between strings are equalized by charging or discharging using a power compensation device so that output through solar power generation is maximized with a simple device configuration, and when there is reduction in output of a plurality of strings, compensation power for maximizing the total string output is calculated to achieve power compensation, whereby the power compensation device performs power compensation with a single discharging part and maximizes the total power generation amount of the strings connected to each other in parallel.
