Abstract: Provided is a method of performing a vehicle-to-everything (V2X) communication and a vehicle electronic apparatus. The method includes controlling a first communication module configured for communication of a first communication type to receive, from at least one external device, a broadcast message indicating information about a communication type supported by the at least one external device, disabling the first communication module based on the broadcast message, and using a second communication module to perform communication with the at least one external device using a second communication type.

Abstract: The present disclosure relates to a sensor network, machine type communication (MTC), machine-to-machine (M2M) communication, and technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services on the basis of the above technologies, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services.

Abstract: The present invention relates to a method for recovering an organic-inorganic element-doped metal oxide from a hydrolysable metal compound, accompanied with contaminated water treatment. The present invention comprises steps of: a) adding a hydrolysable metal compound as a coagulant to a contaminated water to form a separable floc between the hydrolysable metal compound and contaminants present in contaminated water; b) separating the separable floc and the pre-treated water after flocculation treatment; and c) calcinating the separated floc over 500° C. to produce an organic-inorganic element-doped metal oxide. More preferably, the present invention further comprises subjecting the pre-treated water of the step b) to a microwave treatment to cause a photocatalytic degradation of an organic contaminant that remains in the pre-treated water, with the assistance of the remaining hydrolysable metal compound.
