“…Because long-lived active longitudes have been reported by Lanza et al (2019), the star is also a good target to confirm to what extent we can measure the spot area and variation rates of individual spots based on the Kepler's rotational light curve. We analyzed the rotational modulations of Kepler 17 by using the local minima tracing method (Namekata et al 2019) and newly-developed light curve modeling method (Ikuta et al 2019), and compared the results with the spots detected in-transit. The light curve modeling method is developed for the validation of the local minima tracing method.…”

Star spot evolution is visible evidence of the emergence/decay of the magnetic field on stellar surface, and it is therefore important for the understanding of the underlying stellar dynamo and consequential stellar flares. In this paper, we report the temporal evolution of individual star spot area on the hot-Jupiter-hosting active solar-type star Kepler 17 whose transits occur every 1.5 days. The spot longitude and area evolution are estimated (1) from the stellar rotational modulations of Kepler data and (2) from the brightness enhancements during the exoplanet transits caused by existence of large star spots. As a result of the comparison, number of spots, spot locations, and the temporal evolution derived from the rotational modulations is largely different from those of in-transit spots. We confirm that although only two light curve minima appear per rotation, there are clearly many spots present on the star. We find that the observed differential intensity changes are sometimes consistent with the spot pattern detected by transits, but they sometimes do not match with each other. Although the temporal evolution derived from the rotational modulation differs from those of in-transit spots to a certain degree, the emergence/decay rates of in-transit spots are within an order of magnitude of those derived for sunspots as well as our previous research based only on rotational modulations. This supports a hypothesis that the emergence/decay of sunspots and extremely-large star spots on solar-type stars occur through the same underlying processes.

Original teaching materials with dot codes, which can be linked to multimedia such as audio, movies, web pages, html files, and PowerPoint files, were created for use with students with disabilities. Hand-crafted original teaching materials can easily be created by the users themselves—for example, by schoolteachers—with newly developed and easy-to-handle software. A maximum of four multimedia files can be linked to each Post-It sticker icon and/or dot codes overlaid with a specially-designed software (GM Authoring Tool), and such multimedia files are replayed with a specially-designed sound pen (G-Speak) and scanner pen (G-Pen Blue) with Bluetooth functionality just by using the pen to touch the Post-It sticker icon and/or the dot codes on the printed document. Many activities using dot code materials have been successfully conducted, especially at special needs schools. Basic information on the creation of these materials—and on their use in schools—is presented in this chapter.

Original e-book teaching materials containing media overlays were created for use in teaching students with reading disabilities. FUSEe developed by FUSE network, Japan was used to create EPUB 3 e-books, where an audio was replayed with synchronized highlighting of the corresponding text. SMIL language or JavaScript package for iOS, ibooks.js was used to replay the audio reproduction. These EPUB 3 e-books were read effectively with an EPUB 3 reader (for example, iBooks for iOS, and Sony and Kobo Readers for Android). E-books created with special needs school, general school, and Japanese Foreign Language Institute schoolteachers were implemented at many schools for students with reading disabilities and dyslexia. Some assessments of the reading activities were performed to clarify the e-books containing media overlays. Basic information regarding the creation of these e-books and their use in schools is presented in this chapter.
