The Confrontation over the Senkakus and the Transformation of Japan’s Security Strategy During the Abe and Suga Administrations
Get PDFThis paper focuses on Japan’s long-term military response to the new status quo of continuous, if often ritualized, confrontation around the Diaoyu/Senkaku islands between Japan and China. It argues that this new status quo of confrontation has had a large impact on Japan’s military strategy in the East China Sea, with broader implications for Japan’s overall security policy, and even domestic politics. It identifies an emerging Japanese A2/AD strategy over the Ryukyus and Senkaku islands designed to hold at risk any Chinese military and Coast Guard units operating in the vicinity of either. Japan is building an A2/AD bubble over the Ryukyus and Senkakus by deploying anti-ship and anti-aircraft missiles to several islands in the Ryukyu chain, and by developing newer and more long-range missiles, including a new ground launched Hyper-Velocity Gliding Projectile (HVGP) missile for targeting ships and remote islands, with deployment expected as early as 2026. This paper also considers some of the challenges Japan faces in fully developing this A2/AD strategy, including limited land area and the difficulty of moving mobile missile units around populated areas.Article【論文／Articles】departmental bulletin pape
動的幾何環境に関する研究動向と展望―ドラッグ機能に焦点を当てて―
Get PDF本稿の目的は，1980年代から進められてきた図形の教授・学習における動的幾何学環境（DGE）の利用に関する研究動向を概観し，今後の研究課題を明らかにすることである。研究目的に対し，まず，Hoyles（1996）などの先行研究に基づき，DGEと「ドラッグ機能」を定義する。次に，DGEの「ドラッグ機能」が幾何学に及ぼす影響に焦点を当てた先行研究をレビューし，「ドラッグ機能」の限界を指摘する。その結果として，学習者の数学的対象に対する個人的な認識や学習経験の分析について議論する必要がある。この議論を進めるためには，初等教育段階からDGE での教授・学習を実践し，学習者の認識の変化を研究する必要がある。さらに，DGEを使用して幾何学の学習環境の構築のための理論を開発する必要がある。
The purposes of this paper are to review the research trend on the use of Dynamic Geometry Environments（DGE）in teaching and learning of Geometry, which has been advanced since the 1980s, and to clarify the research tasks in the future. On these purposes, first, we define DGE and “drag-function” based on the prior researches, for example Hoyles（1996） and so on. Next, we review the previous researches focusing on the effects of “dragging-function” in DGE on Geometry, and point out the limits of “dragging -function”. As a result, we should discuss about the analysis of learners’ individual recognition of mathematical objects and learning experience focusing on difference with the traditional education or other education by using technology. For that, we need to study the change of learner’s recognition based on experiences of teaching and learning in DGE since the primary education. And more, we should develop the theory of Learning Environments for Geometry with DGE.Article【展望／Original Articles】departmental bulletin pape
