So the Korean, who has been active in a small peninsula attached to the north-east of the huge Chinese continent, gave significant influence to Chinese science and technology with his own creative model.

During the Sejong era of the fifteenth century, in particular, Korean science and technology had reached its climax, thus its accomplishments could reveal themselves clearly in the history of world civilization, let alone of East Asian civilization.

This book contains the great part of my endeavour to realize those cumulative achievements, though I believe there still remain so many related fields that are not dealt in this edition but deserve a thorough investigation.
