舌の先天異常としては,舌癒着症,葉状舌,巨舌症,小舌症,無舌症などがある.そのうちの小舌症,無舌症はきわめて稀な疾患である.我々は,本学小児歯科外来を訪れた8歳5カ月の男児の小舌症に遭遇し,次の所見を得た.1.患児に,小舌症,下顎前歯部の先天性欠損,上下顎の劣成長,高口蓋,口蓋粘膜下破裂を認めた.また,先天性心室中隔欠損症の既往があった.2.舌は口腔底のほぼ中央部に位置し,舌根部に異常はないが,舌体は長さ約2cm,幅約1cmで舌尖に向かって狭いV字状の形態を示した.3.舌の運動,嚥下運動,味覚の異常は認めなかった.また発音は,舌背が軟口蓋に接触してできる「キ」「ギ」「ケ」「ゲ」などの破裂音に歪を認めたが,他の構音障害は軽度で日常会話はかなり明瞭であった.4.妊娠2カ月時の風疹ウイルスによる子宮内感染が原因の1つとして考えられた.5.今後,小舌症自体の手術等による処置は不可能と考えられるが歯列,歯周組織を含めた総合的な口腔管理の必要性があると思われた.

The heteropterous fauna of the Oki Islands lying far-off the Shimane Peninsula, western Honshu, Japan, has been poorly known up to the present. Eighty-six species of Heteroptera from there are listed in the present paper. Of these, 38 are newly recorded from the Islands based on the materials collected by the author's research made in 1984. These 86 species excepting Orius sp. are classified into the following five groups according to the difference in their distributional patterns as shown in the author's papers (TOMOKUNI, 1979,1981). Group 1 contains 18 species of the Oriental origin such as Macroscytus subaeneus. Scotinophara lurida, Nezara antennata, Plautia crossota stali, Leptocorisa chinensis and so on. Of these, Gardena melinarthrum is the most typical species of this group. As far as the author knows, this rare reduviid has been known only from Kyushu in Japan. Group 2 is predominant in the heteropterous fauna of the Islands. It consists of 36 species, that is Megacopta punctatissima, Poecilocoris lewisi, Halyomorpha mista, Homoeocerus unipunctatus, Piocoris varius and so on, distributed within the southern area of the Palearctic Region. Group 3 includes 24 species, whose ranges are limited within the northern part of the Palearctic Region, such as Legnotus triguttulus, Graphosoma rubrolineatum, Dybowskyia reticulata, Carbula humerigera and so no. One of the representatives of this group is Saldula scotica which dwells on the surfaces of large dry stones exposed in mountain streams. The heteropterous fauna of the Islands is comparatively rich in this group considering their low elevation. This seems to be attributed to the richness of vegetation. The 6 species, Nysius plebejus, Acalypta sauteri, Stephanitis takeyai, Amphiareus obscuriceps, Lygocoris (Apolygus) nigritulus and Gerris (Gerris) yasumatsui, are discriminated from the others as Group 4. Though they are endemic to Japan, all of them seem to be of Palearctic origin. Group 5 includes only one widespread species, Zicrona caerulea. The heteropterous fauna of the Oki Islands is rather poor, and most of the known species are common and widely distributed in the other areas of Japan. The following two reasons can be pointed out for this : 1) The area of the Islands is small (348 km^2), 2) The Islands were covered by volcanic products from the end of the Tertiary to the beginning of the Quaternary, though they were isolated on the Sea of Japan at the middle of the Miocene. It is, however, worth noticing that two apterous species, Acalypta sauteri and Schidium marcidum, are distributed on the Islands. The problem when and how the ancestors of these species immigrated in the Islands should be carefully elucidated on the basis of more adequate data than are now at hand.

昆虫神経系で抑制性シナプス伝達を担うレセプターは農業薬剤の重要なターゲットである。本研究では、抑制性グルタミン酸レセプター(iGluR)の組織局在、機能および薬理学的性質を多方面から調べ、薬物作用点としての重要性をγ-アミノ酪酸レセプター(GABAR)と比較した。その結果、GABARの方がiGluRより薬剤ターゲットとしては重要であると考えられた。

This paper explores the expansions and limitations of popular culture consumption in colonial Korea within the wider East Asian regional system/context during the 1930s by examining Yadam, a modern Korean narrative and performance genre. This research challenges previous academic interpretations that focus on domestic popular culture consumption in the colonial period within the boundaries of the nation state. While existing perspectives emphasize a short but "splendid" flourishing of modernity during the 1930s that was subsequently replaced by a colonial period of cultural stifling during the wartime of the 1940s, this research explores the previously excluded transnational spread of' Chosun-esque(Korean)' popular culture by adopting the colonial modernity research arguments regarding the periodic coexistence of modernity and coloniality. Magazine and newspaper articles about Baeknam Yun's Yadam provincial performances as well as internal publications of the Japanese Government General of Korea during the 1930s were analyzed to establish a regional context of the Yadam market expansion beyond the Korean peninsula to Manchuria. The research reveals how the consumption market spread with Chosun farmers emigrating to Manchuria in order to escape impoverished depression era rural Chosun, which was a way for the Japanese Government General to alleviate surplus labor and rural poverty, while it was in the interest of the Japanese government to prevent such influx to mainland Japan, and also served demand for farming labor in Manchukoku. In conclusion, by examining the expansion of the Yadam market situated in the solidifying East Asian regional system during the 1930s, the research traces how people moved and lived across and within the imperial confines of colonial Chosun whilst the formation of an unequal regional market economy.査読研究論文Refereed Papers

多次元反射壁ブラウン運動を用いて複数の株価モデリングを行う.反射壁ブラウン運動はスコロホド方程式と呼ばれる関数方程式から導出された確率微分方程式によって定義されるが、まずその近似解をランダムウォークを用いて構成する。この近似解から株価過程のモデリングを行う。複数の株価はそれらの企業の経済的な関係が強ければ相関が強くなり、ある一定の期間株価を観測すると、近似的に反射壁ブラウン運動と同様の振る舞いをする.このことから、多次元反射壁ブラウン運動によるモデリングとその有効性について考察する.

第5世代移動通信システムでもDual Connectivityが想定され,セカンダリ基地局はビームフォーミングを適用することが考えられる.端末がセカンダリ基地局を切り替えるとき,切替先セカンダリ基地局が端末で特定した1ビームのみを用いて接続動作を行うと,端末移動のため,接続確立に失敗する可能性が高くなる.そこで特定ビームに加え,その隣接ビームも同時使用して接続動作を行うビーム制御を提案する.提案の複数ビーム利用接続確立方式により,特定ビームのみを用いる場合に比べ,端末移動速度30 km/hのときにセカンダリ基地局の切替失敗率を63%以上改善できることを簡易モデル解析とシミュレーションで示している.
