Abstract: Provided is a novel space evaluation system capable of simply and quantitatively evaluating how close an unknown space is to a natural environment. The space evaluation system 1 comprises: a setting unit 12 for setting naturalness as an index of how close a space is to a natural environment; and an estimating unit 11 for estimating, from air quality data indicating a type of material including a microbe included in a sample collected from air in a target space to be evaluated and indicating an abundance of each material, the naturalness of the target space from which the sample has been collected.

Abstract: An information processing system includes: a sample data acquisition unit that acquires, for each sample, sample data in which a first cluster and a second cluster are associated with each other, the first cluster including a plurality of sets of a biological element detected from the sample and a biological element quantity indicating a quantity of the biological element, the second cluster including a plurality of sets of a morpheme regarding text describing an environment in which the sample is present and an appearance frequency of the morpheme; and a generation unit that analyzes a plurality of pieces of the sample data with the biological element quantity and the appearance frequency as parameters and generates information indicating a relationship between the environment and the first cluster.

Abstract: A polyolefin-based laminate film including at least 4 layers which includes a polyolefin-based resin layer; a polyolefin-based mixed resin layer formed on one surface of the polyolefin-based resin layer of which surface is treated by a discharge treatment, the polyolefin-based mixed resin layer containing at least one of petroleum resins and terpene resins in an amount of 5-30% by weight; a vapor deposited metal layer formed on the discharging-treated surface of the polyolefin-based mixed resin layer; and a heat seal layer formed on the surface of the polyolefin-based resin film opposite the surface on which the polyolefin-based mixed resin layer is formed. The laminate film has excellent moisture-proof and gas-barrier properties, and the rejection rate due to blocking in the production process is low.
