NMR Study of Orientational Order in the 7OCB Nematic Liquid Crystal
Mitsuo Machida,T Kakiuchi 한국물리학회 2007 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.51 No.2I
Orientational ordering of 7OCB (4-heptyloxyl-4'-cyanobipheny) in the nematic phase was studied by analyzing the chemical shift of the 13C NMR spectra. The spectra calculated for aromatic carbons reproduce well the observed ones. The obtained orientational order-parameters are 0.444 at 343 K and 0.595 at 315 K.g

Acetone sensitized photoadditions of isopropanol to (5R)-5-menthyloxy-2-(5H)-furanone were investigated in two different microflow reactor systems. Setup A employed a commercially available glass reactor under a UVB-panel. Setup B utilized a FEP microcapillary wrapped tightly around a Pyrex cylinder with a single UVB fluorescent tube at its center. The reactions under flow conditions were subsequently compared to analogue reactions conducted in a batch chamber reactor. Overall, the microflow systems gave faster conversions and higher isolated yields. The flexible microcapillary setup, however, showed the best performance and promise in terms of future scale-up and reactor optimization.

The radial particle flux induced by drift-type fluctuations is observed by use of a gold neutral beam probe in the tandem mirror GAMMA 10. When the drift waves are excited in the plasma, the measured phase difference between the density and potential fluctuations is not zero; the radial profile of the phase difference is not constant. This showed that the radial particle flux had some profile and then the density profile would be varied due to the radial particle transport induced by the fluctuations through the radial particle flux. Experimental results showed the density reduction due to the transport induced by the drift-type fluctuations. The phase difference is an important parameter to decide the radial particle flux. The profiles of the phase difference are measured to understand the decision mechanism of the phase difference. The radial profile of the phase difference is varied by the ion heating power, the density and the potential profiles. As a result, the phase difference had a correlation with the difference between the local drift frequency (the electron diamagnetic drift frequency and the E×B drift frequency) and the observed frequency.
自己評價活動における學習者の意識と評價シ一トの分析 -敎科書を用いる一齊授業の韓國人中級日本語學習者を對象に-

本稿は、自律學習を促すための自己評價活動を改善することを目的とし、敎科書を用いる中級クラスの一齊授業において、アンケ一トによる自己評價に關する學習者の意識調査と、自己評價活動で用いた自己評價チェックシ一トの記述の分析を行った。 その結果、アンケ一ト調査においては、學習者が「自分の實力が把握できたこと」や「學習內容の把握やふりかえりができたこと」を自己評價の利点として捉えている一方で、「客觀的に評價すること」や「自分で考えて評價基準を設定したり、氣づきを記述すること」等に對して難しさを感じていることが分かった。また、自己評價活動が敎科書のPart每に同じ手續きで繰り返されることや敎師フィ一ドバックがないことが、學習者の自己評價に對する動機を低下させ、自己評價は日本語學習の役に立たないと判斷する要因となっていることも明らかになった。 更に、評價シ一トの記述を記述量や記述の多樣さという觀点から、アンケ一ト調査の結果と關連付け、學習者の分類を試みたが、それぞれの分類にある程度の特徵は見られるものの、記述量や記述の多樣さと自己評價に對する認識の間には關連がないと判斷できた。 これらのことから、自己評價活動をより效果的に機能させるためには、記述に關する指導以上に、自己評價の意義や有用性を十分に理解させることや、敎師フィ一ドバック等により自己評價に對する動機付けを行って興味·關心を高めることがまずは重要であるという結論に至った。 The main objective of this paper is to improve self-assessment activities to encourage autonomous learning in intermediate level classroom lesson using textbooks, and this paper carried out a questionnaire survey on the learners’ perception of self-assessment and analyzed Can-do check sheets used in self-assessment activities. The questionnaire survey shows that some learners recognize the self-assessment helps them “to grasp their own ability” and “to grasp the contents of learning and reflection”, while others find the difficulty with self-assessment “to assess themselves objectively”, “to set assessment criteria on their own” and “to describe what they noticed from their learning”. In addition, it was revealed that there are certain factors that reduce the learners’ motivation for self-assessment and learners judge that the self-assessment is useless for their Japanese learning. The factors are the repetition of self-assessment activities for each part of the textbook with the same procedure and no teacher feedback. Furthermore, a classification of learners was attempted associated with the result of the questionnaire survey and descriptive quantity in Can-do check sheets. However, it can be judged that there is no relation between the perception of self-assessment and the descriptive quantity. In addition, from the viewpoint of descriptive contents, it could not be either found any characteristic differences depending on the classification. The result of survey shows that, in order to make the self-assessment activities more effective, it is more important to increase leaners’ interest and concern for self-assessment by making them fully understand the significance and usefulness of self-assessment or motivating them with feedback of teacher rather than teaching how to describe what they noticed from their learning in self-assessment activities.
