On the Hopf Structure of W(2) Algebra and N=1 Superconformal Algebra in   the Ope Language
  Hopf structure of the prototype realizations of the W(2)-algebra and also N=1 superconformal algebra are obtained using the bosonic and also fermionic Feigin-Fuchs type of free massless scalar fields in the operator product expansion (OPE) language.
