1. Given non-negative real numbers \( x, y, z \) satisfying \( x^{2} + y^{2} + z^{2} + x + 2y + 3z = \frac{13}{4} \), determine the maximum value of \( x + y + z \).

2. Given \( f(x) \) is an odd function defined on \( \mathbb{R} \) with a period of 3, and when \( x \in \left(0, \frac{3}{2} \right) \), \( f(x) = \ln \left(x^{2} - x + 1\right) \). Find the number of zeros of the function \( f(x) \) in the interval \([0,6]\).
