Abstract
Most national hospitals and sanatoriums were reorganized into independent administrative corporations, and the National Hospital Organization was established in April 2004. The planning of the feature articles, entitled “Information sharing and the knowledge base in the National Hospital Organization” in this journal is very well-timed, and the articles will be useful for considering what the nation wide hospital network should be in Japan. In these opening remarks, I will survey the knowledge management and comment on some relevant technical terms.
