Abstract: A droplet infection suppression system includes an airflow generator capable of generating an airflow for separating a space into first regions, a first detector that detects human presence in each of the first regions, a second detector that detects coughing or sneezing in the space, and a controller which, when the second detector detects coughing or sneezing, controls the airflow generator to generate an airflow such that a second region including one or more first regions including a first region where human presence has been detected by the first detector is separated by the airflow from other regions.

Abstract: A liquid treatment apparatus includes a liquid storing vessel, a first electrode, a second electrode at least partly arranged inside the vessel, a tubular first insulator surrounding a first-electrode lateral surface with a first space interposed therebetween, and including a first opening in an end surface in contact with the liquid, a tubular second insulator surrounding the first-electrode lateral surface inside the first insulator, a gas supply device supplying gas into the first space and ejecting the gas into the liquid through the first opening, and a power supply applying a voltage between the first and second electrodes and producing plasma. The second insulator is arranged with a second space interposed between the first and second insulators. Portions of the first and second insulators, those portions being positioned inside the vessel, are covered with the gas when the gas is supplied into the first space by the gas supply device.

Abstract: A building evaluation method for evaluating a space inside a building on a basis of features used for certain building certification. The building evaluation method includes conducting a thermo-fluid analysis on the space using a feature value of the space that is set for a first feature and whose change causes a change in an evaluation value of the first feature, the thermo-fluid analysis being conducted under each of two or more conditions between which the feature value is different, calculating, on a basis of a result of the thermo-fluid analysis, a correlation coefficient of an evaluation value of each of second features in relation to the feature value, the features being the first feature and the second features, and finding, among the second features, correlation features, whose calculated correlation coefficients satisfy a certain condition and outputting the correlation features.

Abstract: A cleaning route determination system includes an analyzer that analyzes behavior of airflow and particles inside a facility, a map generator that generates a dust accumulation map indicating one or more dust accumulation areas inside the facility and one or more dust amounts corresponding to the one or more dust accumulation areas, and a route calculator that determines a first route from second routes. Each of the second routes is a route for a cleaner to pass through, within a certain period of time, at least one of the one or more dust accumulation areas. A total amount indicating a sum of dust amounts corresponding to dust accumulation areas included the first route is largest among total amounts corresponding to the second routes, each of the total amounts indicating a sum of dust amounts corresponding to dust accumulation areas included in each of the second routes.

Abstract: An infection risk map provision system includes virus sensors for detecting viruses in the air, the virus sensors being provided at different positions, a communication unit that collects detection information obtained by the virus sensors, and a control unit that provides, on the basis of the detection information, an infection risk map representing the distribution of infection risk information. The control unit sets display granularity for the infection risk information on the infection risk map displayed on an information terminal on the basis of granularity information corresponding to the virus sensors and creates the infection risk map by superimposing the infection risk information upon a map on the basis of the set display granularity and positional information.

Abstract: A liquid treatment device comprises: a first insulator including a first opening and a first inner surface, a gas being emitted into a subject liquid through the first opening; a first electrode that is at least partially disposed within a first space surrounded by the first inner surface; a second electrode that is at least partially disposed within the subject liquid; a gas supply source; and a power supply source. The first inner surface includes a first partial region which contacts the first opening. A forward end of the first electrode protrudes from the first opening to outside the first space, or the forward end retreats from the first opening into the first space by less than 3 mm. A first distance, which is a shortest distance between an outer surface of the first electrode and the first partial region, is 1 mm or greater.
