This application relates to reporting and monitoring a location of a mobile device. Disclosed is an attendance recording service in which when an employee requests attendance recording using a mobile application installed in a smartphone, the smartphone communicates with a server and records clock-in and clock-out of the employee. When the employee selects an attendance recording request button from the mobile application, an analysis is made as to whether the employee is positioned in a workplace, and clock-in or clock-out of the employee is recorded only when it is determined that the employee is positioned in the workplace, thereby maintaining reliable attendance recording.

Method and system for reporting and monitoring location-related activities of mobile devices

An extreme ultraviolet (EUV) collector inspection apparatus and method capable of precisely inspecting a contamination state of an EUV collector and EUV reflectance in accordance with the contamination state are provided. The EUV collector inspection apparatus includes a light source arranged in front of an EUV collector to be inspected and configured to output light in a visible light (VIS) band from UV rays, an optical device configured to output narrowband light from the light, and a camera configured to perform imaging from an UV band to a VIS band. An image by wavelength of the EUV collector is obtained by using the optical device and the camera and a contamination state of the EUV collector is inspected.

To manufacture an integrated circuit (IC) device, a lower structure having a step structure defining a trench is prepared. A material film is formed inside the trench. To form a material film, a first precursor including a first central element and a first ligand having a first size is supplied onto a lower structure to form a first chemisorbed layer of the first precursor on the lower structure. A second precursor including a second central element and a second ligand having a second size less than the first size is supplied onto a resultant structure including the first chemisorbed layer to form a second chemisorbed layer of the second precursor on the lower structure. A reactive gas is supplied to the first chemisorbed layer and the second chemisorbed layer.

Method of forming material film, integrated circuit device, and method of manufacturing the integrated circuit device

Provided are a radical monitoring apparatus capable of monitoring electrical diagnosis of a radical produced by direct plasma or remote plasma and the amount of change of the produced radical, and a plasma apparatus including the radical monitoring apparatus. The plasma apparatus includes a process chamber in which a plasma process is performed, a dielectric film in the process chamber and surrounding sides of a plasma discharge space in the process chamber, and a sensor inside the dielectric film and configured to monitor plasma to thereby monitor a radical generated in the plasma.

An information display method for displaying diverse communication protocol information in order is provided. The communication protocol information display method of a mobile device includes discovering devices connectable through diverse communication protocols, displaying information on the discovered devices, displaying symbols of communication protocols supported by the discovered devices respectively, and displaying image objects associated with applications or functions for use in interoperation with the discovered devices.

Display method and mobile device

A method and apparatus are provided for conveniently managing messages that are received from or sent to external devices through a network by a mobile device. At least one message is displayed and selected by a user for a further operation. Attribute information of the selected message is checked in a message history database. Based on the checked attribute information, a message related to the selected message is displayed. The selected message may be a previously marked message and the related message may be an unmarked message.

Method and apparatus for managing message

A method for dividing and displaying a content unit includes: extracting a sub-content unit which is generated by dividing an original content unit by a preset time interval; displaying the entire sub-content unit when receiving a sub-content unit display command; receiving a jump command that selects a replay time point for an arbitrary sub-content unit among the above sub-content units; and replaying and displaying the original content unit from the replay time point.
