Abstract: Learning guidance tailored to personality, etc., of a user is provided to improve learning efficiency of the user. A transition acquisition section acquires transition of answer status of a user to questions on a test based on operation history information indicating a history of input operations performed by the user on a terminal when the user takes the test. An understanding level estimation section estimates level of understanding of the user of the respective questions on the test using scoring results of answers of the user. A guidance generation section generates guidance regarding learning guidance for the user based on the transition of the answer status of the user acquired by the transition acquisition section and the level of understanding of the respective questions on the test estimated by the understanding level estimation section.

Abstract: The object is to provide a liquid container capable of supplying liquid to a liquid ejection apparatus with simple configuration. Liquid container 100 has liquid containing bag 120 and an introduction member. The introduction member includes the first and second liquid introduction members. The first introduction member has the first spacer unit and the first coupling unit integrally connected to the first spacer unit in which the first groove for letting liquid flow to a liquid lead-out unit is formed. The second introduction member has the second spacer unit and the second coupling unit integrally connected to the second spacer unit in which the second groove for letting liquid flow to the liquid lead-out unit is formed. The first and second liquid introduction members are adjoined so that the surface on which the first groove is formed and the surface on which the second groove is formed face each other.

Abstract: This composition for forming a charge-transporting thin film, which contains an organic solvent and a charge-transporting substance precursor that has a 9-t-butoxycarbonyl carbazole structure in the molecule, yields a thin film that exhibits excellent charge transport properties even when firing is performed at a low temperature. As pertains to the charge-transporting substance precursor, the composition can be prepared using a low-polarity solvent that causes less damage to a substrate or a member comprising an organic compound than is the case with a high-polarity amide-based solvent, etc.
