A system and method of processing a mailing label through a postal service that requires an account that can be charged for generating the mailing label are described. The systems and methods also extract, using facial structure analysis software of the facial structure analysis system, at least one facial structure variable value from the facial structure data and obtain a predicted potential difficult intubation value using an airway classification model and the at least one facial structure variable value. The constructions of the fabrication process and PDP enables the normal temperature combinationattachment so as to increase product efficiency by reducing a process time and improve product quality by preventing the panel characteristic reduction.
