Differing from conventional approaches for improving sexual dysfunction of an adult man being commonly carried out by letting the adult man administer a dosage of synthetic drug or a composition of Chinese herbal medicines, the present invention particularly discloses a method for treating male sexual dysfunction by using underpants comprising far-infrared fibers. A variety of clinical data have proved that, after wearing this underpants for 3 months, both the men diagnosed with sexual dysfunction and the men not sure to suffer from sexual dysfunction have an apparent progress on improvements of their erectile ability, erectile quality, ejaculation control ability, and lower urinary tract symptoms (LUTS). Moreover, clinical data have also proved that, despite the fact that a male person wears the underpants provided by the present invention for three months, there is no adverse effect induced by the underpants for causing the physiological condition of the men be abnormal.

Systems and methods for augmented-reality tutoring can utilize optical character recognition, natural language processing, and/or augmented-reality rendering for providing real-time notifications for completing a determined task. The systems and methods can include utilizing one or more machine-learned models trained for quantitative reasoning and can include providing a plurality of different user interface elements at different times.

A modular learning device comprising of a base board having a frame with plurality of sides, a network of tracks having a spinal track and several other tracks; a plurality of sliding blocks; and a plurality of wisdom cards having an identifier section, a margin having same number of sides as the base board, a plurality of zones in the margin, and a middle area, a solution code for the problems or situations, each wisdom card containing different problems or situations, and an indicator for each problem or situation, for generating the solution code. The wisdom card may be on academic, linguistic, cultural and behavioral subjects, including situations for persons with physical or mental constraints. A plurality of base boards can be unified by a complementary construction to use combination wisdom cards for cross learning of two or more subjects and for learning several languages together.

A wide range of subjectsacademic, linguistic, cultural and behavioural, cross learning of two or more subjects, learnable using wisdom card can be deployed in the modular learning device, including problems or situations for persons with specific physical or mental constraints. A plurality of base boards can be unified by a complementary construction so as to use combination wisdom cards for cross learning of two or more subjects and for learning several languages together.
