A method and electronic device are disclosed herein. The electronic device includes a display, a communication unit, a processor and a memory storing instructions. The process executes the instructions to implement the method, including establishing wireless communication with one or more IoT devices, displaying a user interface for managing IoT devices, receiving a user input selecting a group of IoT devices, transmitting first information including user account data to an external server, transmitting second information to another device, the first information also indicating a selected group of IoT devices, and the second information causing the other device to communicatively connect with the first external server.

Method for managing and controlling external IoT device and electronic device supporting the same

Provided herein is a method of preparing a bile acid derivative using a continuous flow reaction. When bile acid derivatives are synthesized using a continuous flow reaction according to the present invention, the reaction is very safe compared to an existing batch-type reaction, the reaction time is significantly reduced, and high-quality bile acid derivatives may be synthesized with high efficiency. In particularly, according to the present invention, a hydrogenation reaction proceeds under substantially water-free reaction conditions, and thus the conversion rate (UDCA: CDCA) of a UDCA hydrogenation reaction may be significantly enhanced.

Method for bile acid derivative by using continuous flow reaction

An air conditioner, having an outdoor unit and an indoor unit, to perform a heating operation and a defrosting operation, the air conditioner including a detection unit to detect a state of at least one selected between the outdoor unit and the indoor unit and to output the detected value, a controller to determine whether the air conditioner is in a stable state when the defrosting operation is completed and, upon determining that the air conditioner is in the stable state, to control the detected value output from the detection unit to determine entry time of the next defrosting operation, and a storage unit to store a value detected in the stable state. The entry time of the defrosting operation is accurately determined, thereby minimizing the number of times of the defrosting operation during the heating operation.

Air conditioner and control method thereof

A compressor capable of reducing oil foaming and reducing the waiting time taken until the heating of the compressor is completed, and a method of controlling the same, the method of controlling a compressor including sensing temperature of the oil in the compressor, if the temperature of the oil is below a reference temperature, performing a loss operation, in which an amount of heat radiation of the motor part is increased, while operating the motor part at a low speed, and if the temperature of the oil increases to be equal to or higher then reference temperature, performing an efficiency operation by converting an operation of the motor to a normal operation.

Compressor and control method thereof

A power supply includes a rectifier circuit to rectify power, a smoothing circuit unit to smoothen a voltage of the rectified power, and a voltage drop circuit unit to drop the smoothened voltage. The voltage drop circuit unit includes an electric charge storage circuit to output the voltage-dropped voltage, a resonance circuit to receive first current from the smoothing circuit unit and to supply second current to the electric charge storage circuit, and a current interruption circuit to control the first current and the second current using zero current switching for performing switching when current does not flow using a resonance circuit.

Power supply and DC-DC converter with voltage drop circuit therein
