Abstract: A multilayer electronic component includes a body including a plurality of dielectric layers, side margin portions disposed on the body, and external electrodes disposed on the body. The reliability of the multilayer electronic component is improved by controlling the contents of Si for each position of the dielectric layer and the side margin portion.

Abstract: The present disclosure relates to a fusion protein of Z-domain and calsequestrin having improved reactivity, stability, and antibody recovery, and a method of isolating and purifying antibodies using the same. Specifically, the present disclosure relates to: a nucleic acid encoding a fusion protein of Z-domain and calsequestrin having improved reactivity, stability, and antibody recovery; a recombinant expression vector including the nucleic acid; a host cell transformed with the recombinant expression vector; and a method of isolating and purifying antibodies by using the fusion protein of Z-domain and calsequestrin having improved reactivity, stability, antibody recovery, and purity.

Abstract: A signal detection apparatus includes a signal reception unit, an Analog to Digital (A/D) signal processing unit, and a user interface unit. The signal reception unit receives an external signal. The A/D signal processing unit determines whether the received signal is an abnormal signal based on a plurality of signal profiles having different signal characteristics, and obtains the abnormal signal if, as a result of the determination, it is determined that the received signal is the abnormal signal. The user interface unit displays the abnormal signal.

Abstract: An exercise step with air-cushioning legs. The exercise step (1) includes a plate-shaped panel (10), and air-cushioning legs (30). Each of the air-cushioning legs is provided under the panel to support the panel, and absorbs a load applied to the panel by air cushioning effect. The exercise step has a high air cushioning effect, thus protecting a user's knees from injury, allowing the user to exercise in comfort and safety, and minimizing noise generated during a cushioning operation. Further, the exercise step prevents the panel from being deformed due to a load applied to the panel.
