Abstract: A server and a method of controlling a group action of the server are provided. The server can determine whether a conflict occurs between a first group action that is being executed and a second group action that is requested to be executed and determine at least one conflict solution, and the method controls the execution of the group actions by the server and the determination and communication of the conflict solution. The conflict can be determined by using group action characteristics of the first group action and the second group action.

Abstract: A mobile terminal and a method operating the same are provided. The method includes generating a list of a service that may be provided to an external via a Local Area Network (LAN), transmitting the generated service list to the external terminal, receiving a request for providing a service that is included in the service list from the external terminal, and connecting the mobile terminal to the external terminal via the LAN and providing the requested service to the external terminal.

Abstract: Disclosed is a method of controlling a display of an electronic device. The method may include: determining a current situation of the electronic device by using at least one piece of state information on the electronic device and surrounding information on the electronic device by the electronic device; and turning on or off at least some areas of the display according to the determined current situation by the electronic device.

Abstract: Provided are an anode active material for a lithium secondary battery having high reversible capacity and excellent charge/discharge efficiency, comprising a complex composed of ultra-fine Si phase particles and an oxide surrounding the ultra-fine Si phase particles, and a carbon material; and a method for preparing the same. The present invention also provides a method for preparing an anode active material for a lithium secondary battery comprising producing a complex composed of ultra-fine Si particles and an oxide surrounding the ultra-fine Si particles by mixing a silicon oxide and a material having an absolute value of oxide formation enthalpy (?Hfor)greater than that of the silicon oxide and negative oxide formation enthalpy by a mechanochemical process or subjecting them to a thermochemical reaction to reduce the silicon oxide; and mixing the Si phase-containing oxide complex and carbon material.
