The fracture toughness Jc of the material in the ductile to brittle transition temperature (DBTT) region shows test specimen thickness (TST) effect and temperature dependence, and apparently increases when compressive residual stress is applied. In this paper, as TST effect and temperature dependence, the fact that Jc apparently increases due to compressive residual stress is attributable to the loss in the one-to-one correspondence between J and the crack-tip stress distribution, and then, the fracture prediction of the specimen with compressive residual stress was performed using the T-scaling method proposed by the authors, and its validity was confirmed for high strength steel of 780 MPa class and 0.45 % carbon steel JIS S45C. In addition, it was suggested that the minimum of Jc with compressive residual stress can be predicted by requiring only the tensile test.

The middle Pleistocene time range is defined here the period before the last interglacial in the Brunhes epoch. In Japan, the Shimosa-Kazusa Groups around the Tokyo Bay in Kanto and the upper part of the Osaka Group in Kinki both represent the standard middle Pleistocene sequences and have been studied in detail. These groups are characterized by the cyclic sedimentation caused by transgression and regression corresponding to climatic changes.The purpose of this paper is to attempt the correlation of the Kazusa Group and the Osaka Group by identification of widespread marker-tephras. Accurate determinations of the refractive indices of volcanic glass, orthopyroxene and hornblende, together with other determinations, have enabled successful characterization for correlation to be made for several tephra layers in southern Kanto and Kinki. The following marker-tephras are found over two districts, resulting in the establishment of several important datum planes in the middle Pleistocene sequences.The vitric tephra called Ks 11, which is sandwiched in the Kasamori Formation and its correlatives in southern Kanto, can be identified as a marker tephra of the Osaka Group called Sakura ash, in the vicinity of Osaka and Kyoto. The estimated age of this tephra, about 450, 000 years, is based on its stratigraphic relationship with the underlying dated tephra, Kinukawa ash (460, 000-470, 000 years). Stratigraphically, it is included in the deposits immediately below the transgressive horizon (Tama-f and Ma 7) and also occurrs in the biozone of Stegodon orientalis in both districts. The vitric tephra called Ku 1, sandwiched in the Kokumoto Formation, is identified and correlated with a tephra called Imakuma I ash. It is included in the deposits immediately above the Brunhes-Matuyama boundary. The very important dated tephra, Azuki ash (870, 000 years), in the Osaka Group, can be correlated with Ku 6C tephra in the lower part of the Kokumoto Formation by their peculiar petrographic properties. Both are sandwiched in the deposits below the Brunhes-Matuyama boundary.From the relationship between the identified tephras and marine sequences, it is concluded that during the period from 700, 000 years to 450, 000 years at least three interglacial-glacial cycles are recorded, and that after 450, 000 years the following major interglacial episodes are indicated; 450, 000YBP, 370, 000YBP, 300, 000YBP, 230, 000YBP, and 130, 000YBP.

[Purpose] The purpose of this study was to measure gluteal pressure and center of force (COF) during sitting in children with cerebral palsy (CP). [Subjects and Methods] The participants were five children with CP and five typically developing controls. We measured peak gluteal pressure and COF using the TekScan system. During the measurements, all children sat on the therapeutic table for 1 minute without back and foot support. [Results] The peak gluteal pressure and COF in children with CP were significantly higher than values in controls. [Conclusion] This study suggests that it is important to distribute hip pressure evenly and transfer COF in a forward direction during rehabilitation in children with CP.

学校歯科保健は,児童生徒が歯・口腔の健康に関する知識・習慣・態度への変容を期待して行われる保健活動の1つで,養護教諭は常にその要として「保健教育」と「保健管理」に携わってきた。また,平成7年度に学校保健法の改正が行われ,健康診断票や健診内容は大幅に変わった。これは,従来からの検診を中心とした健康管理から,本来求められていた健康教育を積極的に取り入れるものとして注目されている。そこで,千葉市内の養護教諭171名を対象に,児童生徒への口腔保健教育の進め方や学校健診の評価など10項目について,Delphi法によるアンケート調査を行った。その結果,(1)健診時の器具の消毒についての回答では,公的機関が診査器具を一括管理し必要な時期に必要な量を配送してもらうことを希望するものが1回目は51.8%であったが,2回目以降は71.5,72.8%と回を追うごとに回答率が上昇した。(2)学校現場で行える事後措置としては,「保健だより」などを利用した「家庭との連絡」と回答したものに集中して72.3〜83.1%であった。(3)学校でのフッ化物洗口については,「必要ない」と回答しているものが50.4〜57.8%で,「実施が望ましい」は12.7〜17.7%あった。Delphi法の特徴の1つである収束傾向は,「新しい健診法の全体的評価」,「要観察歯の導入」,「年間の健康診断の回数」,「診査器具の消毒」,「学校保健委員会の活動」および「学校歯科医とかかりつけの歯科医との関係」の設問にみられたが,特に診査器具の消毒についての「業者に依託する」応答に顕著に示された。
