漢字の学習方法を身につけることで漢字学習に対する負担感を減らせないだろうか，という観点から，大学の交換留学生を対象に2015年度前期のクラス活動のための教材を作成した。その作成の経緯，内容，実施結果を報告する。教材の使用後のアンケート調査と事後テストの結果，漢字の学習方法についての知識をあまり持たない学習者からは教材が役に立つと評価されたが，授業での扱い方や，改善すべき点なども検討課題として見つかった。

平安時代の古辞書『新撰字鏡』所引の『切韻』を扱った専論としては, 上田［1981］ が実質唯一のものであり, その成果は上田［1984］に反映されている。ただし, それぞれ問題点も少なくない。『新撰字鏡』の依拠『切韻』については, 上田［1981］が長孫訥言『切韻』の系統としているが, 貞苅［1989］では下平声部分のみ異なることを述べている。本稿ではまず, 貞苅［1989］のいうごとく下平声部分のみ異質であることを例示し, その特徴が「唐韻」系のものであることを指摘する。続いて, 上田［1981］が長孫訥言『切韻』の増訂本として挙げた例証に問題が多いことを述べる。また, 上田［1981, 1984］では『切韻』反切の誤った採録例を挙げているが, そうした特殊な引用がほかにも多数見られることを, 実例を挙げて示す。

On the basis of data obtained from boring and surface survey to Quaternary sediments in the district under consideration, has it become clear that thickness of the alluvium is less than 15m. and early to middle Pleistocene formations lie under the Alluvium.
Besides standard penetration test to these sediments indicates that N value of Alluvial fine to medium sand and silt is not more than 10 at shallower than 5m. underground, while that of Diluvial sand is more than 25 at deeper than 15m. But as for gravel, their N value is not always in proportion to depth where they 1ie.
The Alluvium is composed mostly of shallow sea sediments, on the other hand, the Diluvium contains very often tuffs, and lacustrine materials in the lower part and bay ones in the upper.

The formation of the Oda District during the Ritsuryô Period is un-documented. We may safely assume, however, that formation took place in the Pre-Taika Period by the aggregation of parts of the two agata of Kibi-Naka and Kawashima to Hokuki which, consequently, became the central part of the Oda District.
Oda is the name of both the whole district and the central part of the district. Many names connected with the Gûke (District Office) have been found in the central part and the Kôri-gongen-gu, which was probably the central shrine for the entire district during the Ritsuryô Period, is still extant.
The so-called Oda Umaya (Oda Relay-station) was probably located in Maido east of Oda. Many roof tiles from the temple which was probably the Gunji (the district temple connected with the Gûke) have also been found in Maido.
Since both Oda, which gave its name to the whole district, and Maido, which is near Oda, show traces of having been centers of the district, we conclude that the Gûke was established in Oda.
The San-yo Road is thought to have passed through the southeastern part of the Gûke area; thus, we can infer that the Gûke had easy access to land transportation. Moreover, since the Gûke was situated on the Oda River, it must have been connected to good water transportation links.
Judging from the fact that three different Jôri systems have been found in the comparatively small Oda valley, it seems certain that the Gûke was established at the time when the Jôri systems were being enacted. As the southern side of the Gûke is 6 cho (about 654 meters) in length, it can be assumed that the Gûke was 6 cho square.

This paper clarifies that the Late Pliocene to Middle Pleistocene formations distribute in the Hiji area, north of Beppu Bay and these formations are correlated to the Takio Formation of the Oita Group in the Oita area, south of Beppu Bay, where is a standard area for the late Cenozoic stratigraphy in Kyushu.
The Oita Group in the Hiji area is stratigraphically divided into the Hiji Formation, Oga Formation, Katano Volcanic Rocks and Kanagoe Volcanic Rocks in ascending order. Lower member of the Hiji Formation yields marine molluscan fossils living in coastal water associated with oceanic water and they indicate Late Pliocene to Early Pleistocene. The Hiji Formation consists of hornblende andesitic pyroclastic rock and marine elastic rocks, and the Oga Formation consists of augite hypersthene andesitic pyroclastic rocks and fresh water elastic rocks. The Katano and Kanagoe Volcanic Rocks are hornblende augite hypersthene andesite and augite hypersthene andesite lavas respectively.
Change of volcanic activity in the Hiji area coincides with that of the formations corresponding to the Takio Formation in surroundings of the Hiji area. Because the basal part of the Hiji Formation suffers epithermal alteration, age of the Usa Group in the marginal area of Beppu Bay which was correlated to Miocene must be reviewed.

本研究は，漢字書字の習得が困難な学習障害児における国内の研究動向を調査し，今後の課題を明らかにすることを目的にした．漢字書字の習得が困難な要因には視覚情報処理や聴覚情報処理を問題とする報告が多かったが，書字成績に認知スタイルや筆順の正確さが寄与した報告も見られた．また介入研究では，単一事例研究法を用いた研究は少なかった．今後は単一事例研究法を用い，認知スタイルだけでなく，書字運動や運動覚心像に着目した研究や，各児童の特性に適応した介入方法をフローチャート化し自主学習しやすいツールを開発していくことが求められる．併せて，Information and Communication Technology（ICT）を活用した支援の普及も重要である．

【目的】読み書きに困難を抱える児童を対象に、視覚関連基礎スキルアセスメント（WAVES）を用いて視覚認知機能を評価し、支援への活用を検討すること。

【対象および方法】対象は2020年3月から2021年6月の帝京大学病院小児科LD外来受診者のうち、WAVESと見る力に関するチェックリストを実施した30名（男児25名・女児5名、年齢9.8±2.1歳）。WAVESを行い下位検査評価点と4つの指数を算出した。

【結果】下位検査評価点の平均値の多くが標準値より低かったが、線なぞりの合格点と比率、形なぞりの比率は標準値より高かった。4つの指数では、視知覚＋目と手の協応指数（VPECI）と視知覚指数（VPI）が標準値より低く、VPIが最も低かった。目と手の協応全般指数（ECGI）と目と手の協応正確性指数（ECAI）は標準値より高かった。

【考按】視知覚指数（VPI）は読み書き困難を持つ児童では低く、過去の報告と同様の傾向を示した。眼科検査、言語検査、心理検査と合わせてWAVESを活用することで苦手の背景にある児童の特性を推測し、読み書き指導に有用な情報を与える可能性がある。
