The definition of the absolute value for a fuzzy number is obtained.Furthermore,a lot ofproblems,such as absolute integrability,bounded variation and absolute continuity,arepresented and discussed.The representation theorem of the absolute values of fuzzy num-bers is established.It plays an important role in discussing the problems conceming theabsolute value.The relation between the absolute integrability and integrabili-ty is discussed,and the following result is obtained:aintegrable fuzzy-number-valued function is absolutely integrable iff it is integrable.The relation between theabsolute integrability and the absolute continuity of the primitive for fuzzy-number-valuedfunctions is dealt with.It is also pointed out that a fuzzy number valued function is ab-solutelyintegrable if and only if its integral primitive is fuzzy absolutely continuous.

Explores what is challenged now concerning the empirical turn of the philosophy of technology in view of the cause and effect of the development of cultural criticism on technology The classical cultural criticism on technology is discussed through an analysis made for the contradiction between Heidegger's phenomenological standpoint based on existentialism and his hermeneutic methodology taken for studying the philosophy of technology Then, the inexhaustiveness of empiristic methodology that is currently prevailing in cultural study on technology is discussed further to expound the necessity for "embodying" as an empiristic methodology to study the technological culture The way to spread over the embodying in technological study is therefore taken into account to deepen the empirical turn of philosophy of technology
