Abstract: A plasma processing apparatus includes a chamber, a lower and upper electrodes vertically spaced apart from each other in the chamber, a RF transmitting part connected to the lower electrode and configured to supply RF power to the lower electrode, a ground plate spaced downwardly from the lower electrode, and an insulating member laterally surrounding a cavity formed between the lower electrode and the ground plate. The cavity is isolated from a region under the ground plate by the ground plate.

Abstract: In accordance with an aspect of the disclosure, an electronic device is provided. The electronic device comprises a first subscriber identity module (SIM) and a second SIM, a first communication circuitry configured to perform wireless communication over a cellular network, a second communication circuitry configured to perform wireless communication over a Wi-Fi network, and at least one processor operatively connected with the first SIM, the second SIM, the first communication circuitry, and the second communication circuitry. The at least one processor is configured to perform a packet-based call associated with the first SIM using the first communication circuitry, and transmit a first re-registration message for internet protocol multimedia subsystem (IMS) re-registration for the second SIM to a network associated with the second SIM using the second communication circuitry, during the packet-based call associated with the first SIM.

Abstract: A system verification method includes generating a first verification vector as a result of a first action of an agent, the first verification vector referring to an observation corresponding to at least one state already covered, from among states of elements of a target system, identifying a first coverage corresponding to at least one state covered by the first verification vector, from among the states of the elements, updating the observation by reflecting the first coverage in the observation, and generating a second verification vector through a second action of the agent, the second verification vector referring to the updated observation.
