Owing to increasing the frequency of dance performance, the interest of dance has been raised socially in the 1980`s. But, coming up to the 1990`s, dance culture has not reached the expectations both to activate socially more than before and to enlarge the base of the nostalgia class. On the other hand, some performances advertised by mass media, such as a performance by a famous foreign dance company, can attract audience`s interest. Therefore in order to activate dance culture, public information should be required. Today is called an information-oriented society. All through the world, information has been put to practical use, and the structure has begun to change fundamentally across the all aspects of politics, economy, society, and culture. At once information technology and network development lead the world to unite one, and bring about a sharp competition among countries for the 21 st century. Informationized change has proceeded as a course of social change, and the core of information society is a computer. The development of communication by a computer has made Internet place one of the most important media which is used by all the people in the world. As as result, to industrialize Internet has been proceeding with rapidity. The development of information technology, which can make mutual communication possible unlike a common mass medium, has already settled as a medium of next generation. And as a method of public information, internet has been used widely. Considering a present situation of using Internet on domestic dance culture, there is little professional and satisfactory website on dance except showing its contents and photographs for the purpose of advertise a performance. In the scopes of music, culture, art, and movie, however, it not only offers detail information and public information but also achieves industralization of it. As a result, the interest on it leads to be industrialized in reality as well as cyberspace. As a subject of 400 persons who majored and are engaging in dance, their informationized senses were researched. The results are as follows; First, the result of information infra shows the rate of holding a computer is 58% of all the respondents and 53% of not-holding a computer will purchase it in one or two years. Second, on PC communication or Internet use, 42% use it one or two hours a month, 8% one or two hours a day, 20% one hours a day. Utilizing network appears low. Third, as the result of informationized mind, 99% responded that professional Internet service on dance should be needed. Fourth, many responded choreography, establishment of dancing signs, and public information can be possible by using a computer. That is, science of dance should be necessary. According to the above, persons who majored and are engaging in dance recognize the need of information, but don`t take an active advantage of it. Therefore, their positive attitude to accept will be required and the activation of dance culture will be led as education of a new learning. The reason why culture industry considers Internet as business of public information results from rapid increase of Internet and PC communication users. And the interest of culture art has been raised through Internet and Internet and PC communication by a computer has been made better use of acquiring materials on culture art. Dance culture should notice the flow of information across the whole society. It is an inevitable object to which we should be adapted, for future audience and its activation. In conclusion, public information on dance culture by using network, which is being spreaded as a medium, should be accomplished for potential future audience. Not it can be done by an individual, but the entire dance culture should be adapted and activated for our informationized society.
