The invention described herein provides for methods and systems for determining, selecting, andor treating diseases and conditions caused by or associated with high quantities of methanogens in a subject, or diseases and conditions caused by or associated with low quantities of methanogens in a subject. A plurality of terminals and an extruding arm for extruding the external electronic device, which extruding arm is an insulator and moves elastically, are adapted in the jacks. Insulating layers are applied to the bond pads-forming surfaces of the semiconductor chips, and via-holes for exposing bond pads are formed in the insulating layers. When the media stream discontinuity rate associated with the portion of the media stream is greater than the lower media stream discontinuity threshold, the method may further include determining a quality of experience associated with the portion of the media stream based upon, at least in part, a payload associated with the portion of the media stream.
