To assess the prevalence of various radiological reduction methods for childhood intussusception in training hospitals by means of a nationwide phone survey, and to demonstrate recent trends in this area by comparing the findings with those obtained in a survey conducted. $BaTiO_3$ system was prepared by using fabrication of classical conditioning ceramics. Polycrystalline and surface structure characteristics of the specimens were measured by X-ray diffraction, SEM(Scanning Electron Microscopy) and EDAX (Energy Dispersive Spectrometer), respectively.
