Query: Gauged R-symmetry, Fermion and Higgs Mass Problem   We consider the simplest model of $SU(3) \times SU(2) \times U(1)_Y \times
U(1)_R$ gauge symmetry with one extra singlet field whose vacuum expectation
value breaks the horizontal $R$-symmetry $U(1)_R$ and gives rise to Yukawa
textures. The $U(1)_R$ symmetry is able to provide both acceptable fermion mass
hierarchies and a natural solution to the $\mu$ problem only if its mixed
anomalies are cancelled by the Green-Schwarz mechanism. When the canonical
normalization $g_3^2=g_2^2={5\over3}g_1^2$ of the gauge coupling constants is
assumed, the Higgs mass parameter $\mu \sim m_{3/2}$ can arise taking into
acount the uncertainty in the ultraviolet relation $m_e m_\mu m_\tau/m_d m_s
m_b \simeq \lambda^q$ with $q \neq 0$. When $q=0$ is taken only a suppressed
value of $\mu \sim \lambda m_{3/2}$ can be obtained.
