    “eポートフォリオによる自己教育力の育成 : モバイル端末を活用した参画型看護基礎教育で培うキャリア形成”が文部科学省平成20年度「質の高い大学教育推進プログラム」に選定され、キャンパス館内に無線ローカルエリアネットワーク(LAN)環境を構築した。それにより、平成21年4月から、従来の設置型パソコンを用いた有線LANに加え、モバイルパソコンを用いた無線LANの活用が可能となった。今回は、島根県立大学短期大学部・出雲キャンパスにおいて構築した無線LANの概要とその環境下における看護基礎教育における活用について紹介する

    Repeated Relative Gravity Measurements in Sakurajima Volcano (October 2021 and March 2022)

    Relative gravity values were repeatedly measured at 19 gravity points in and around Sakurajima Volcano in October 2021 and March 2022, to monitor spatiotemporal mass variations associated with volcanic activity. The gravity values obtained from 1998 to 2022 showed a clear increase of up to +4.3 Gal/yr in the central part of the volcano. The gravity increase can be explained by the point mass increase of 8 × 109 kg/yr under the center of the volcano at a depth of 3 km below sea level. This result implies that volcanic mass continuously increases under Sakurajima Volcano, even during the quiet period of eruptive activities at the Minami-dake crater

    Relative gravity values were repeatedly measured at 19 gravity points in and around Sakurajima Volcano in October 2020 and March 2021, to monitor spatiotemporal mass variations associated with volcanic activity. The gravity values obtained from 1998 to 2021 showed a clear increase of up to +4.3 μGal/yr in the central part of the volcano. The gravity increase was even observed by the LaCoste’s G31 and G375 gravimeters; these gravimeters have been used at Sakurajima Volcano since 1975, and their temporal variations in reading values are negligibly small these days. These facts indicate that the gravity increase observed in the central Sakurajima is the actual one, because the artificial gravity change due to temporal variation of instrumental scale factor is expected to be small for the G31 and G375 gravimeters. The gravity increase can be explained by the point mass increase of 1.9×10¹⁰ kg/yr under the Kita-dake summit at the depth of 3 km below sea level. This result implies that volcanic mass continuously increases under Sakurajima Volcano, even during the quiet period of eruptive activities at the Minami-dake crater
