Hello.
I have just bought an Arduino UNO R3 and I got here two power supplies but I don't know if they are appropriate for supplying energy to my arduino.

The first one reads:

I.T.E. POWER SUPPLY
MODEL: HK-J206-A12
PRI.: 100-240V ~ 50/60Hz 0.2A
SEC.: 12V DC 0-0.5A (SET AT 0.5A)


And the second:

I.T.E. POWER SUPPLY
MODEL NO: UWP01211075U
INPUT: 100-240V~ 50-60Hz  0.5A
OUTPUT: DC 7.5V  1.3A


PS: where I wrote "DC" it was actually this symbol:

Are any of these fitting for arduino?

Thanks in advance.
Best regards.

That is the symbol for DC.

Both would work.  I'd recommend the 7.5V.  The on-board regulator will generate less heat when running compared to the 12V supply, meaning more current is available to your project.
