how the number of (/) in the URL affect page rank...?

Hi all, I would like to hear your opinions about how the number of
subdirectories (/) in the URL affect the google page rank..or not?

I mean, I have the following URL

www.mysite.com/english/infomation/museum/art.aspx

(with 3 levels)

or

www.mysite.com/english_infomation_museum/art.aspx
(with 1 level)

Has the second URL any advantages in terms of page rank ??
I would like to kow if there are any advantages in minimizing the
number of levels (/)....


Thanks All


ALberto
