Papers commonly end with "Conclusions" or a "Summary". The two are not the same. Conclusions are just that - the inferences that can be drawn from your data, not a reprise of the entire paper. In a sense, this may be a list of the main points you want the reader to take away from reading your paper - the points demonstrated by your research. A summary, on the other hand, is indeed a recapitulation of the entire paper that hopefully incorporates the main conclusions. A summary is usually redundant and unnecessary. Conclusions, on the other hand, may be very useful to drive home the key points, especially for readers who have waded through the discussion but are still asking "So what is the bottom line here?".
