The present invention relates to prognostic methods which are useful in medicine, particularly cancer chemotherapy. According to the invention, an oxidation catalyst that promotes the oxidation effect of hydrogen peroxide-based compounds with a trace amount of the composition, and has excellent effects of suppressing the decomposition of hydrogen peroxide-based compounds and suppressing coloration of the catalyst itself, and a bleaching composition containing the oxidation catalyst can be utilized. A multivariate statistical analysis of the operation of the process is implemented based on the model data and the process measurements. In other embodiments true binocular 3D images can be displayed directly to viewers, without the need for special 3D viewing glasses. A plurality of input streams may be multiplexed into a single output stream.
