also query heavy, try change , check difference:

select u.name user_name, dp.name dept_name `user` u inner join query       q on  u.id = q.user_id left  join profile     p on  p.id = u.profile_id left  join degree      d on  d.id = p.degree_id left  join department dp on dp.id = d.department_id order u.name;
