     View Summary

    SARS-CoV-2 is the causative agent of COVID-19, which is a global pandemic. SARS-CoV-2 is transmitted rapidly via contaminated surfaces and aerosols, emphasizing the importance of environmental disinfection to block the spread of virus. Ultraviolet C radiation and chemical compounds are effective for SARS-CoV-2 disinfection, but can only be applied in the absence of humans due to their toxicities. Therefore, development of disinfectants that can be applied in working spaces without evacuating people is needed. Here we showed that TiO2-mediated photocatalytic reaction inactivates SARS-CoV-2 in a time-dependent manner and decreases its infectivity by 99.9% after 20 min and 120 min of treatment in aerosol and liquid, respectively. The mechanistic effects of TiO2 photocatalyst on SARS-CoV-2 virion included decreased total observed virion count, increased virion size, and reduced particle surface spike structure, as determined by transmission electron microscopy. Damage to viral proteins and genome was further confirmed by western blotting and RT-qPCR, respectively. The multi-antiviral effects of TiO2-mediated photocatalytic reaction implies universal disinfection potential for different infectious agents. Notably, TiO2 has no adverse effects on human health, and therefore, TiO2-induced photocatalytic reaction is suitable for disinfection of SARS-CoV-2 and other emerging infectious disease-causing agents in human habitation.

  • UVC disinfects SARS-CoV-2 by induction of viral genome damage without apparent effects on viral morphology and proteins

     View Summary

    Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has been a pandemic threat worldwide and causes severe health and economic burdens. Contaminated environments, such as personal items and room surfaces, are considered to have virus transmission potential. Ultraviolet C (UVC) light has demonstrated germicidal ability and removes environmental contamination. UVC has inactivated SARS-CoV-2; however, the underlying mechanisms are not clear. It was confirmed here that UVC 253.7 nm, with a dose of 500 μW/cm2, completely inactivated SARS-CoV-2 in a time-dependent manner and reduced virus infectivity by 10–4.9-fold within 30 s. Immunoblotting analysis for viral spike and nucleocapsid proteins showed that UVC treatment did not damage viral proteins. The viral particle morphology remained intact even when the virus completely lost infectivity after UVC irradiation, as observed by transmission electronic microscopy. In contrast, UVC irradiation-induced genome damage was identified using the newly developed long reverse-transcription quantitative-polymerase chain reaction (RT-qPCR) assay, but not conventional RT-qPCR. The six developed long RT-PCR assays that covered the full-length viral genome clearly indicated a negative correlation between virus infectivity and UVC irradiation-induced genome damage (R2 ranging from 0.75 to 0.96). Altogether, these results provide evidence that UVC inactivates SARS-CoV-2 through the induction of viral genome damage.

     View Summary

    <p>Few studies have comprehensively screened for ionic small molecules with high water-solubility in the traditional Japanese mandarin orange <i>Citrus unshiu </i>Marc. Here, we performed metabolomic analysis with capillary electrophoresis-mass spectrometry (CE-MS) to comprehensively identify and accumulate gross quantitative data for water-soluble components in the different varieties of 'Aoshima' and <i>'</i>Okitsu/Miyagawa Wase', according to grade and processing method. In this analysis, we focused on 151 components and showed the characteristic components related to each different variety and processing method, e.g., Met, Gly, and Asp in var. Wase; ornithine, putrescine, synephrine, and Gln in var. Aoshima; and pyroglutamate, GABA (<i>γ</i>-aminobutyric acid), and malonate in the juice of var. Aoshima. Furthermore, we conducted processing tests and identified components that were affected by squeezing or heating. These data represent basic data for further investigation of the metabolism of <i>C. unshiu </i>Marc. or chemical changes in their components due to external factors such as processing.</p>

  • Development of a National Integrated Agricultural Field Data Application Programming Interface (API) that Combines Field Polygons, Agricultural Field Pins, and Soil Map Data

     View Summary

    <p>In this research, we proposed a national integrated agricultural field data API that combines field polygons, agricultural field pins, and soil map data. To improve the convenience of using agricultural field data as the foundation of agricultural production, we organized various data related to agriculture as well as current conditions and problems with the data collaboration platform WAGRI, which is commonly used in agriculture in Japan; we then created an integrated national agricultural field data API. Three types of data were targeted: field polygons, agricultural field pins, and soil maps. We tried to integrate the field pins and soil maps based on field polygons and were able to completely integrate 5,999,291 of the 31,591,036 basic data points, for a success rate of 19.0%. The remaining data could not be integrated because some data were missing and there were format differences, including the existence of multiple integration targets. To solve this problem, the rules for preparing the target agricultural data must be unified. API's output formats are GeoJSON and WebMapTileService (WMTS), which are standard formats in geographic information systems. We confirmed the API was more convenient to use because a user can obtain three data types in one request. To improve widespread use, we still need to speed up data integration and add a mechanism that can download many types of data at once.</p>

     View Summary

    © 2018 IEEE. We propose an Agri-InfoScience platform which addresses the need for skill transfer in response to various food problems associated with global population growth. The platform consists of various tools and methods for collection, analysis and reconstruction of information. The agricultural skill learning support system is the central tool of the platforms. This system serves to address the issues pertaining to the acquisition of 'master craftsmanship.' We conducted an experiment using kiwi pruning operations as an example of a skill that takes a few years to acquire to verify the effectiveness of the learning support system.
