BACKGROUND Although the socioeconomic burden of 2009 pandemic influenza A (H1N1) was considerable, no reliable estimates have been reported. Our aim was to compared medical costs and socioeconomic burden resulting from pandemic influenza A (H1N1) 2009 with that of previous seasonal influenza. METHODS We estimated the medical costs and socioeconomic burden(More)
Many researchers who use laboratory-scale synthesis systems to manufacture nanomaterials could be easily exposed to airborne nanomaterials during the research and development stage. This study used various real-time aerosol detectors to investigate the presence of nanoaerosols in a laboratory used to manufacture titanium dioxide (TiO2). The TiO2 nanopowders(More)
Fungi are the known sources of irritation associated with atopic diseases (e.g., asthma, allergic rhinoconjunctivitis, and atopic eczema). To quantitatively estimate their presence in the indoor environment of atopic dermatitis-inflicted child patient's houses (ADCPHs), the high-efficiency particulate air (HEPA) filters installed inside the air cleaners of(More)
Benzene is one of the target compounds to be removed from air owing to its carcinogenicity. In this study, benzene oxidation with ozone over a MnOx/KIT-6 catalyst was carried out for the first time. MnOx/KIT-6 was synthesized using two different Mn precursors: Mn acetate and Mn nitrate. The characteristics of the synthesized catalysts were examined by X-ray(More)
