| Outline of Final Research Achievements |
In order to keep the sanitary conditions around the kitchen, toilet, and bathroom clean and to maintain a comfortable living environment, a theoretical analysis method is required to propose hygienic materials, surface treatments, and operating conditions that prevent the growth of biofilm stains. Therefore, based on the ultra-accelerated quantum molecular dynamics method, by applying the particle-level dynamic Monte Carlo method and the macro-level computational fluid dynamics that deal with the bacterial cells, a completely new "Quantum-Based Multiscale Computational Chemistry" in the field of hygiene engineering was established.
