If you just want to have a traditionalform output, you can do it like 
this :

MakeBoxes[Log[a_], TraditionalForm] := RowBox[{"ln(", a, ")"}]

Afterwards, all the traditionalform ouptuts will write ln(x) instead of 

But I'm not sure that it is a good idea... Maybe we better just get used 
to the Mathematica habits!

The natural logarithm function in "traditional form" in Mathematica 


This is "not a bug but a feature", but in mathematics the natural 
is just ln(x) or even ln x.
The true traditional notation use log for decimal logarithm, ln for 
logarithm, lb for binary logarithm, and
log_{b}x  for logarithm with base b. Unfortunatelly in most computer
programs (see FORTRAN) LOG
stands for natural logarithm (an exception is Pascal).

Nevertheless, how to force to use ln(x) instead log(x) ?

The brute way is use /.Log->ln//TraditionalForm.

Is any more elegant way to do this?
