The Middle East City: A Harmonious Enviroment for Modern Man February 2-5, 1985, Paris, France   Dr. Yitzhak Kayutman makes a point, with illustrations of plans to restore Beirut in the background.   Participants have a good laugh over lunch.   L-R: Prof. Saad Eddin Ibrahim, Dr. Abdullah Schleifer, and Dr. Hoda Subhi on the results of rapid  urbanization in Cairo.   Discussions were frank, sometimes intense, but there was also room for humor.
