The Kirishima volcanoes located in southern Kyushu are comprised of more than 20 volcanic edifices. The volcanoes occupy an elliptical area of approximately 330km^2 with the WNW-ESE direction. Among the different types of volcanic edifices, the typical ones are compound maars and lava flows in Ebinokogen. We studied the volcanic history of Ebinokogen by geological examination of tephra layers and lava flows. After the Karakunidake-Kobayashi plinian eruption, seven tephra were formed in this area. We determined the ages of those tephra and two lava flows. The magmatic eruptions, produced Tamakino B tephra, occurred after Karakunidake-Kobayashi tephra eruption. The first activity in Ebinokogen from about 9.0 cal ka BP generated Fudoike lava flow, and Fudoike-Tamakino A tephra erupted from Fudoike crater. Karakunidake north-Ebino D tephra was generated from the northwest flank of Karakunidake at 4.3 cal ka BP, with debris avalanche and lahars. Phreatic Fudoike-Ebino C tephra erupted from the Fudoike crater at 1.6 cal ka BP. Ioyama-Ebino B tephra eruption started from around the 16^<th> to 17^<th> century with lava flow. Phreatic Ioyama east-Ebino A tephra erupted from Ioyama east crater in 1768 AD. The Ebinokogen area is one of the active regions of Kirishima volcanoes explicated by geophysical observations. Our results indicate cyclical tephra depositions mainly produced by small magmatic and strong phreatic eruptions in this area after the Karakunidake-Kobayashi pyroclastic eruption. Furthermore, the vent locations were found to migrate with each eruption.

The data collected in Hiroshima and Nagasaki during the past 40 years on the children of survivors of the atomic bombings and on the children of a suitable control population are analyzed on the basis of the newly revised estimates of radiation doses. No statistically significant effects emerge with respect to eight different indicators. Since, however, it may confidently be assumed some mutations were induced, we have taken the data at face value and calculated the minimal gametic doubling doses of acute radiation for the individual indicators at various probability levels. An effort has also been made to calculate the most probable doubling dose for the indicators combined. The latter value is between 1.7 and 2.2 Sv. It is suggested the appropriate figure for chronic radiation would be between 3.4 and 4.5 Sv. These estimates suggest humans are less sensitive to the genetic effects of radiation than has been assumed on the basis of past extrapolations from experiments with mice.

マガキ由来の新規の抗酸化物質(DHMBA)において、肝培養細胞を用いた抗酸化能の観察、及び非アルコール性脂肪肝炎(NASH)モデルマウスを用いた肝病変の改善効果を検証した。肝培養細胞を用いた実験では、DHMBAは酸化剤に対する細胞保護作用や酸化誘導性のアポトーシスに対する抑制効果が観察された。NASHモデルマウスを用いた実験では、DHMBA を高濃度含むマガキ抽出物によりNASHの肝臓特有に見られる病理組織学的症状の改善、及び抗肥満、インスリン抵抗性の改善が見られた。これらのことから、DHMBAは酸化ストレスが発生原因と考えられているNASHの予防や治療に有効と考えられた。

Transparent epoxy resin root canal models were used to evaluate vertical condensation techniques for obturating lateral canals. The root canal model was configured with a straight main root canal and four right-angled lateral canals at 1.0 and 3.0 mm from the apex. Root canal obturation was performed with Thermafil, Obtura II, or NT condenser. Obturation volume in lateral canals was measured by three-dimensional microcomputed tomography, and one-way analysis of variance was used to analyze differences between groups. Lateral canals at 1.0 and 3.0 mm were uniformly filled by all obturation methods. Among the three obturation methods, Thermafil resulted in the highest obturation volumes for all lateral canals.

This paper proposes a new field-weakening control considering voltage saturation for vector controlled induction motor. The proposed method improves the output torque characteristics in the field-weakening region. The effectiveness of proposed method is verified by the experimental results.

Careful measurements of the changes induced by photoquenching in the infra red transmission image of GaAs wafers at Liquid Nitrogen temperature shows an important enhancement of the mean light level and disappearance of the usual fourfold feature; but it also shows that the contrast of the pattern (cell structure) is not affected at all. The contribution of EL2 centres to the image is questioned; it is deduced from these results that photoquenchable EL$^{0}2$ centres are slightly more abundant in the cells than in the walls. In large cell materials an intermediate zone is found surrounding the cells and containing higher EL$^{0}2$ densities. This sheds new light on the role of the dislocations; these results are discussed and compared with etching and luminescence images.
