Abstract: The present invention relates to a non-oriented film, a laminated body, and a package; the non-oriented film has a sealant layer composed of a resin composition including 30 to 90 mass % of a propylene-based polymer (A) and 10 to 70 mass % of a 1-butene/?-olefin copolymer (B), and a substrate layer; the propylene-based polymer (A) has a melting point (Tm) measured by differential scanning calorimetry (DSC) of 120° C. or higher and 135° C. or lower, and contains 50 to 90 mol % of a propylene-derived constitutional unit; the copolymer (B) has a melting point measured by DSC of lower than 120° C. or has no melting point observed by DSC, and contains 50 to 99 mol % of a 1-butene-derived constitutional unit and 1 to 50 mol % of an ?-olefin-derived constitutional unit (provided that a total of the 1-butene-derived constitutional unit and the ?-olefin-derived constitutional unit is 100 mol %), the sealant layer has a thickness of 3 to 30 ?m, and the substrate layer has a thickness of 10 to 100 ?m.

Abstract: The present invention provides a method for easily and quantitatively evaluating a degree of fatigue of a human being, a kit therefor, and an application thereof. Specifically, by measuring a concentration of amino acid in plasma taken from a subject, the degree of fatigue of the subject in daily life can be easily and quantitatively evaluated. Furthermore, an in vivo anti-fatigue effect of an anti-fatigue substance and that of an anti-fatigue food product can be measured.
