In this paper, the EPICS2017 photoatomic database was used to evaluate the photon mass attenuation coefficients and buildup factors of soils collected at different depths in the Philippine islands. The extraction and interpolation of the library was accomplished at the recommended linear-linear scales to obtain the incoherent and total cross section and mass attenuation coefficient. The buildup factors were evaluated using the G-P fitting method in ANSI/ANS-6.4.3. An agreement was achieved between XCOM, MCNP5, and EPICS2017 for the calculated mass attenuation coefficient values. The buildup factors were reported at several penetration depths within the standard energy grid. The highest values of both buildup factor classifications were found in the energy range between 100 and 400 keV where incoherent scattering interaction probabilities are predominant, and least at the region of predominant photoionization events. The buildup factors were examined as a function of different soil silica contents. The soil samples with larger silica concentrations were found to have higher buildup factor values and hence lower shielding characteristics, while conversely, those with the least silica contents have increased shielding characteristics brought by the increased proportions of the abundant heavier oxides.

The curiosity of the human afterlife created many imaginations. The Death Angel's Character are also the product of this imagination. This is because we needed a connection between this world and the otherworld in human' imaginations. The Death Angel revealed in detail in Shamanistic Epics. First, It is the person who performs the task assigned by The King of the Otherworld. Second, It is a person who can go to this world and the otherworld. Third, It is the person who takes the deceased to the otherworld. Fourth, It is the person who takes out the soul of human and modify the life list. Fifth, It is the person who sympathetic and humane qualities. This The Death Angel's character is actively accepted in modern contents. The most representative works are <49 Days>, , . Contemporary content, but the otherworld and the afterlife were accepted. And The Death Angel played an important role. Of course, this process also happens that modern changes. Namely, Function and personality retains existing character. And the appearance and background change a modern sense. As a result, The Death Angel became a new character through the encounter between the past and the present.
