The recent relationship between Japan and Korea has become closely aspect of politics, culture, and so on. There are many research activities cooperated with Korean researchers in Kyushu University. This is because Kyushu University is one of core stations about gigabit network between Japan and Korea. Many experiments of the advanced applications were performed using this network. However most of them were demonstration held by professional, and we thought the consideration for demonstration by amateur was very interesting. So we made a opportunity that freshmen, what is called absolute end user, performed demonstration experiment in lecture form. We focus on actual remote communication with Korean researchers using DVTS system in this paper, as a part of curriculum for freshmen in Kyushu University as a consideration of demonstration. Especially we focus on way to preparation of system and configuration of the remote class.
