  • We investigate the inducing method of irrational numbers in junior high school, under algebraic as well as geometric point of view. Also we study the treatment of irrational numbers in the 7th national curriculum. In fact, we discover that i) incommensurability as essential factor of concept of irrational numbers is not treated, and ii) the concept of irrational numbers is not smoothly interconnected to that of rational numbers. In order to understand relationally the incommensurability, we suggest the method for inducing irrational numbers using construction in junior high school.

  • The absence of the commensurable general mass media system theory has been problematic in empirical communication studies. This study first suggests the static mass media system theory based on modified Habermas's two level society, and then develops the dynamic mass media system theory based on the boundary-agencement theory that synthesizes Luhmann's boundary theory and Delueze & Guattari's agencement theory. In the static mass media system theory, the mass media system interpenetrates other social subsystems and the life world as a part of the cultural system coordinated by generalized language media. In the dynamic mass media system theory, the mass media system is a boundary of all social subsystems. The mass media system also articulates its self-referential observations to other-referential observations from other subsystems, mediated interpenetrations between the social subsystems and the life world. Especially, performances in the mass media system deterritorizes social systems to the life world, and reterritorizes the life world to social systems. The general mass media system theory can provide commensurability for various empirical mass media system studies, and prevent biases when researchers choose research topics.
