Extended Distribution System for Electronic Document Distribution as the Application Realized on the Network Introducing DACS Scheme

An Electronic medium is not always used in the educational sites all over the world for teaching. This is because of the following two drawbacks. First, it is difficult for a teacher to understand the laws governing the document distribution in educational site on own country. Second, when the teacher is not very computer savvy, managing document distribution becomes troublesome and stressful. Therefore, a system that facilitates easy document distribution is required. However, because laws have already been established in each country, developing a system on the basis of the system requirements that are derived from those laws produces a different system in each country. Therefore, we aim at realizing a standard system by considering the common factors all over the world for developing a system. As a first step, the system that facilitates distribution through an electronic medium in the educational site is proposed and examined under the two factors: time factor (whether it is class time or not) and physical factor (whether the student is present in classroom or not), i.e., under a face-to-face class. Such a system is called a document copying/distribution system that conforms to copyright protection laws (Distribution System). The Distribution System has a single drawback for the user and for the network administrator. In this paper, to solve these drawbacks, a DACS portal realized by a dynamic display function of a static document realized on the network introducing Destination Addressing Control System (DACS) Scheme is applied to the Distribution System. A mechanism that is easy to use for the user and is easy to manage for the network administrator is realized.
