Abstract: An electronic device comprising: a sensor; a memory; and a first processor, wherein the first processor is configured to: receive first data of a user of the electronic device sensed at preconfigured intervals via the sensor; identify second data comprising location information of the user or information input by the user; compare the first data and the second data with threshold values pre-stored in the memory to generate a result; detect a current health state of the user based on the result; output recommended guide information based on the detected current health state; and re-detect the current health state of the user based on changed first data received at the preconfigured intervals and the second data.

Abstract: A method for the treatment of water, the method comprising the steps of anaerobic uptake and storage of at least a portion of the organic components in the water by a heterotrophic denitrifying biomass absorption of ammonium ions with an ammonium ion absorbent; and aerobic oxidation of the absorbed ammonium by a nitrifying biomass comprising ammonium oxidizing microorganisms, wherein the step of aerobic oxidation of the absorbed ammonium is preceded by the step of exposing at least a portion of the nitrifying biomass to atmospheric oxygen.
