不織布の飽和透水係数を用いた排水過程における水分特性曲線の推定

素材の異なる土木用不織布に対して保水性試験を実施し排水過程における水分特性曲線を求めた．その結果と既往研究から読み取った水分特性曲線にvan Genuchtenモデル（以下，VG式）を適用し，不織布の飽和透水係数を用いた排水過程における水分特性曲線の推定について検討した．その結果，不織布の水分特性曲線は，素材が異なる場合おいても土質材料と同様にS字型の形状となり，VG式によって評価することができることを示した．また，不織布の飽和透水係数から推定したVG係数を用いた水分特性曲線の予測式の誤差は0.5～2倍程度であり，不織布の飽和透水試験を実施するだけで，不織布の排水過程の水分特性曲線を推定できることが示唆されることを示した．Articleジオシンセティックス論文集.31:149-154(2016)journal articl

Item factor analysis with target rotation for the one hundred and twenty items of the Yatabe Guilford Personality Inventory

The Yatabe Guilford Personality Inventory was developed for measuring the twelve traits of personality (Tsujioka, 1957). Although ten items for each trait were selected using the item analysis method (item-total correlation), some researchers have questioned the dimensionality of the one hundred and twenty items of this inventory. In this research, we conducted item factor analysis for the one hundred and twenty items using the target rotation method with Weighted Least Square Mean and Variance adjusted of Mplus. The results of twelve factors were evaluated according to the principle of factor-trueness by Cattell and Tsujioka (1964). The communality of each scale of ten items was compared with alpha coefficient as an index for estimating the reliability of the scale. By examining the sixty-six figures of two-dimensional plotting for the factor patterns of one hundred and twenty items and twelve scales, the implications of the methodology for scale development were discussed.YG性格検査は、12のパーソナリティの特性を測定するために開発された (辻岡、1957) 。各特性の10個の項目は、項目分析法 (項目－合計相関) によって選択されたにもかかわらず、一部の研究者は、この検査の120個の項目の次元性について疑問を提起した。この研究では、MplusのWeighted Least Square Mean and Variance adjustedで解を推定し、ターゲット回転法を使用して、120個の項目の項目因子分析を行った。12因子の結果を、Cattell and Tsujioka (1964) による因子的真理の原理の観点から評価した。尺度の信頼性を推定するための指標という観点から、10項目からなる尺度の共通性をアルファ係数と比較した。120項目と12尺度の因子パターンについての66個の2次元プロット図を吟味しながら、尺度開発の方法論について議論した

新規蛍光プローブ探索のための C2C12 細胞を用いた機能性組織の再構築

The second near-infrared window ranged between 900 and 1400 nm, namely NIR-II, has advantages for deep tissue imaging with extrinsic fluorophores due to lacking autofluorescence, low light absorption, and reduced scattering. Most of the proposed probes were used for labeling with antibodies. As a new application, we plan to monitor electrical activity in a living tissue noninvasively using membrane potential dye with NIR-II fluorescence. So we need the excitable cell culture system to screen candidates of such dyes. C2C12 skeletal myoblasts were morphologically differentiated to myotubes under the optimal conditions, and the electrical stimulation-induced contraction of the myotubes was monitored optically. This myotube system would permit screening membrane potential dyes in NIR-II

複合不織布の細孔構造や物理的性質に及ぼすWater Jet二次圧の影響

Nonwovens are used widely in technical textile applications, but it is necessary to advance apparel industry to get a further growth of Japanese nonwovens industry. In apparel applications, however, various types of characteristics such as clothing comfort, good absorbency, durability, drapeability, shape stability. Strength and elongation etc. are required. In this study, we try to apply nonwovens to apparel uses by using compounding technique for different nonwovens such as spunlace and spunbonded nonwovens. The purpose of this study is to develop the multilayer composite nonwovens which is useful for apparel clothing and medical care sheet by using compounding techniques with high pressure water jet. Especially, we measured effects of secondary water jet pressure on the pore structure and physical properties of composite nonwovens

複合不織布の性能に及ぼす構成要素の影響

The compounding is one of the most important technology for the development of nonwovens products. So far many composite nonwovens has been developed. However, there are few examples studied about the effects of composite components on the composite nonwovens. In this study, we aimed at clarifying the effects of the components in the composite nonwovens developed for the medical and healthy sheet. As a result of investigating many experiments, the properties of composite nonwovens is influenced considerably by specific components, and then the multilayer composite nonwovens could be used for the object for medical and healthy shee
