This paper deals with a design of a CSCL (computer supported collaborative learning) referred to as "ProjectBoard", which displays an awareness of task status and division of labor in project-based learning (PBL). According to the situated learning theory, learners learn not only the cultural practice but also the "legitimate learning strategy" which refers… (More)

Networks around home electronics are a recent development. Assuming that home networks will develop in the future, we have been working on networks systems of gas appliances. This paper starts with a description of the existing state of IT usage in gas appliances and the company’s efforts thus far in this field. It then introduces a home network system of… (More)

This paper first introduces cyclic vector multiplication algorithm (CVMA) that is a multiplication algorithm in extension field. Then, it is also introduced that CVMA is useful under the tight restrictions of pairing-based cryptographies. Then, this paper points out a problem about the calculation cost of CVMA. For this problem, this paper proposes an… (More)
