This means that, in case of the domestic aspect, the function of communication visitors with museurns and feedback between them is very important, while, in case of the overseas aspect, the construction of the network among nations’ museums is urgent. Therefore, this paper aims to look into effective exhibition composition centering on intangible cultural properties by the use of positive communication and computer network and to be used as basic data for culturing participation-oriented museums in the 21st century.

In case of the latter, museurns pays a sincere attention to achieve themore compact and systernic exhibition composition in order not to lose the intention of information search about exhibition and exhibition data, which seems to lose it because of too much information resulting from the networking among museurns of countries. To sum up, the 21st century museum shows a new direction that museurn intend to by coping with various demand of its change with the advanced digital techniques in off-line and on-line places. And this change initiates the capability of constructing communication based on people, performing the global network and thus having museun's challenging to the future.
