A Comparison of Solving Process of Problems in Exercises by Frequency of Brain Wave

本研究は、基礎的な学習課題（宣伝的知識（漢字の書き取り）と手続き的知識（一次方程式））を紙面上とVDT(Visual Display Terminals)の二つの学習メディア提示形態で被験者に行わせ、脳波の周波数分析を用いて、教育メディアの提示方法の違いが学習者の学習心理にどの様な影響を及ぼすかを脳波性状から比較分析した。開眼安静時と学習時αブロッキングを基準とした脳波の周波数解析の結果から、学習課題解決時の学習者の心的状態を考察した結果、VDTでの作業の方が一般的に緊張状態になりβ波が大きく作業能率がよいとは限らない、学習での脳波成分の個人差が大きい等の知見を得た。In this paper, we describes the comparative experiments to the students on solving process of Problems on declarative knowledge (Kanji dictations) and procedure knowledge (ichiji equation) in Exercises in both in VDT works and on desktop works by Frequency Analysis of Brain Wave. The difficulties of Kanji dictations are various. And α reduction rate in brain wave in each brain work (Kanji dictation and ichiji equations) were comparatively analysed. As the results, it was elucidated that VDT works are more impressive to the brain work than desktop works. And, by frequency Analysis of Brain Wave, the defferences of αreduction rate between individuals are recognized to be so high

Reservoir formations are often very heterogeneous and fluid flow is strongly determined by their permeability structure. Thus, when a scale inhibitor (SI) slug is injected into the formation in a squeeze treatment, fluid placement is an important issue. To design successful squeeze treatments, we wish to control where the fluid package is placed in the nearwell reservoir formation. In recent work1, we went "back to basics" on the issue of viscous SI slug placement. That is, we re-derived the analytical expressions that describe placement in linear and radial layered systems for unit mobility and viscous fluids. Although these equations are quite well known, we applied them in a novel manner to describe scale inhibitor placement. We also demonstrated the implications of these equations on how we should analyse placement both in the laboratory and by numerical modelling before we apply a scale inhibitor squeeze. An analysis of viscosified SI applications for linear and radial systems was presented both with and without crossflow between the reservoir layers. In this previous work, we assumed that the fluid being used to viscosify the SI slug was Newtonian1. However, the question has been raised concerning what the effect would be if a non-Newtonian fluid was used instead. We mainly consider the effect of shear thinning although our analysis is generally applicable if the non-Newtonian flow rate/effective viscosity function is known. We address the questions: (i) Does the shear thinning behaviour result in more placement into the higher or lower permeability layer (in addition to the effect of simple viscosification)? (ii) Can the shear thinning effect be used to design improved squeeze treatment?</p
