Abstract: The present disclosure relates to a Mitochondria-Associated endoplasmic reticulum Membrane (MAM)-specific fluorescence calcium sensor and the use thereof. The present disclosure can surmount the limitations of a conventional technique in that verification of calcium migration through MAM requires separate measurements of calcium ion concentrations within ER and mitochondria and situational explanations of the phenomena, and can directly measure concentrations in the paths through which calcium ions move to exclude influences on calcium ion changes through numerous different calcium ion channels existing in mitochondria, thereby providing a convenient and accurate MAM-specific calcium ion sensor.

Abstract: A refrigerator and a method for controlling the same are disclosed. The refrigerator may minimize the size and material cost of the control system by controlling the internal temperature and the speed of a compressor using a thermostat used in the conventional low-capacity/low-cost refrigerator without using a system controller equipped with various sensors (internal sensors and/or external sensors) capable of controlling the internal temperature. In addition, since an inverter controller capable of controlling a BLDC compressor estimates the internal/external temperature based on operation information of the compressor, and determines the internal load, it may save energy and reduce vibrations and noise, which are the largest disadvantages of a constant-speed compressor, thereby improving satisfaction of the consumer. In addition, the BLDC compressor may be started and operated stably by applying a differentiated algorithm of the inverter controller.
