404 Page Not Found in Codeigniter - php

Question

I am new to CodeIgniter and experiencing the following error after creating new model for the purpose of user dashboard in addition to admin dashbaord. It is really great if some one can help me. I checked previous answers in the StackOverflow but none helped me.
I am experiencing following error.
Code segment relevant to the error is as follows.
