Abstract: Provided is a technique for facilitating evaluation of a relationship between persons in work. An information processing device according to one embodiment includes: an acquisition unit that acquires an achievement value for each work representing an achievement of each work obtained when a plurality of workers is combined and allocated to the work; a calculation unit that calculates an evaluation value for each work by comparing the achievement value for each work with a reference value; a determination unit that determines quality of a relationship between the plurality of workers based on the evaluation value for each work; and a setting unit that sets, based on a result of the determination, a relationship value numerically representing the quality of the relationship between the plurality of workers.

Abstract: Provided are: a beverage which contains an increased amount of xanthohumols, in which an unfavorable sour after-taste specific to xanthohumol compounds including xanthohumol and isoxanthohumol is suppressed; and a method for producing the beverage. This beverage contains one or more compounds selected from xanthohumols, and an iso-?-acid, wherein the total content of the one or more compounds selected from xanthohumols is 3 ppm by mass or greater, and the content of the iso-?-acid is 0.5-80 mass ppm.

Abstract: A plurality of metallic members are laminated via corresponding insulating members to form a metallic layered structure. Then, an energy beam is irradiated onto the metallic layered structure to generate an electric energy through the interactions between the metallic members of the metallic layered structure and the energy beam. The electric energy is extracted from the metallic layered structure. The metallic members are made of at least two kinds of metallic materials with respective different atomic numbers.

Abstract: A plurality of metallic plates are arranged alternately so that the main surface of one of the metallic plates is faced to the main surface of the adjacent one of the metallic plates. The metallic plates are classified into two kinds of plates with different thicknesses. Then, energy beams are irradiated perpendicularly onto the main surfaces of the metallic plates to generate an electric energy by interactions between the energy beams and the metallic plates.

Abstract: A method of encouraging a customer to visit a hair salon is provided. The method includes the steps of deriving an expected date of visit of the customer and producing direct mail containing suggestions of hairstyles that can be applied to the customer when the expected date of visit of the customer is a predetermined period ahead.
