i'd like to now if their is a simpler way to do that :

IN_NEWS=@h['IN_NEWS']

because here i do have to know their is a key of name "IN_NEWS"

want i want is to affet the value of all the @h['key_name'] to the
variable key_name ???

(as far as i remember well it's possible in php then i think this is
also possible in ruby ))))

Thinking out loud...

hash.each_key{|k|
   eval("#{k}=hash[#{k}]")
}

There may be a better way, though...
