What is this pipe on our pool deck?

We have a mystery pipe on our pool deck in Southern California. Photos are here:

Do you think it contains electrical wires? If so, would it be 110V AC or 220V AC? It's located in a place that might be suitable for an outdoor (electric?) grill. Or perhaps it's a gas pipe, for a permanent BBQ/grill?

The markings on the top cap include the word KOREA. Other symbols look like a bell, and maybe the number 15 or 16. The round symbol I can't decipher.

The pipe's outside diameter is 0.37 inches.

Any suggestions would be much appreciated! Don't want to mess with it until I have a better sense of what's in there.

Almost 2 years later, I have the answer -- it's a gas pipe.
Being galvanized and many decades old, its long underground run started leaking. The Gas Company rep had a meter, which led him along our pool deck (with drains) in the direction of this pipe stub.
So, I guess the idea was to provide for a BBQ, which nobody ever installed.
I found the run originating under the house, heading in that direction, and had it cut and capped there.
Thanks everybody for your comments here.

Thanks for letting us know. Glad you got it sorted.
