convert week of the year into a date string

[Ananda Kumar]

HI All,
I have table which stores week_of_the_year and year.
For example

week_of_year        YEAR
32                          2008

I want to convert this into the date. That is , i need to get the date of
first day of the week 32.
some thing like

03-AUG-2008.

Regards
anandkl
