Abstract: Presented are an apparatus and a control method, which execute an artificial intelligence (AI) algorithm and/or a machine learning algorithm and recommend a do-not-disturb mode based on a context recognized by an electronic equipment user in a 5G environment connected for the Internet of Things (IoT). An apparatus control method includes collecting user context information including time information and place information from at least one of data stored in a sensor, a communication module, or a memory of an electronic equipment, determining the recommendation of a do-not-disturb mode by applying the user context information to a learning engine, and displaying, on a display, a user interface capable of setting the do-not-disturb mode based on the determination of the recommendation of the do-not-disturb mode.

Abstract: Disclosed are an apparatus and control method for recommending an application based on a recognized situation of a user of an electronic device by executing an artificial intelligence (AI) algorithm and/or machine learning algorithm in a 5G environment connected for the Internet of Things and a driving method thereof. The apparatus control method according to an embodiment of the present disclosure includes applying context information including at least one of environmental information collected through a sensor of the electronic device or a network, or usage information generated by the use of the electronic device to a machine learning based first learning model in response to a user input, and displaying, on a display, a first shortcut related to an application determined on the basis of a result of applying the context information to the first learning model and displaying, on the display, a second shortcut related to a preset application.

Abstract: An islanding detection apparatus minimizes a reduction in power quality and detects islanding when distributed generations are operated in parallel. Also, another islanding detection apparatus for parallel distributed generations synchronizes parallel distributed generations by periodically applying a reactive current at a half cycle. Further, another islanding detection apparatus for parallel distributed generations easily synchronizes parallel distributed generations even when inverters installed in the respective distributed generations are fabricated through different makers.

Abstract: A method of fabricating a printed circuit board is disclosed. A method of fabricating a printed circuit board that includes: stacking an insulation layer on at least one surface of a core layer, on which an inner circuit is formed, and forming an outer circuit pattern; burying the outer circuit pattern in the insulation layer; removing the outer circuit pattern to form minute grooves and curing the insulation layer; and forming an outer circuit by filling metal in the minute grooves, makes it possible to readily form high-resolution fine-line circuits, as well as to reduce fabrication costs and increase productivity.
