7例の構音障害児について,外的語音弁別能力(他者が発した語音を弁別する能力)を聴覚的絵ポインティング課題にて検討した.対象とした構音障害児は,すべて構音訓練を受けたことがなかった.健常3歳児および4歳児(各10例)を対照群とした./k//s/を語頭音とした2モーラ語「かめ」「さめ」に,後続音を統一した「あめ」「まめ」を加えた四分の一選択課題を行い,正答数および語彙選択率を算出し,反応時間を計測した.その結果,語頭音/k/を置換している構音障害児群の外的語音弁別能力は,健常4歳児群と同程度であった.しかし,語頭音/s/を置換している構音障害児群に関しては,健常3歳児群と同程度の外的語音弁別能力であることが示唆された.構音障害児の外的語音弁別能力には,構音の誤り方の種類によって,弁別しやすい音と弁別しにくい音がある可能性があり,正しい構音の獲得には,自己の産生音に対する構音の自覚が重要であると考えられた.

An anologue quartz timepiece, Cal. 7A28, the first Analogue Quartz Chronograph in the world, is reported here, which is operated by four independent driving motors. Cal. 7A28 is an Analogue Quartz Chronograph with the improved levels in time measuring efficiency, time accuracy, reliability, and maintenance, and also is an analogue quartz timepiece including complicated and multiple functions. In this paper, the operating performance, structure of the movement, and the electronic circuit are discussed in connection with the fine mechanism and the microelctronics. This paper may serve to promote analogue quartz timepieces equipped with multiple functions.

The single shot fast spin echo single thick slice method(single slice method)is a technique that visualizes the water component alone using a heavy T_2. However, this method is considered to be markedly affected by changes in the viscosity of the material because a very long TE is used, and changes in the T_2 value, which are related to viscosity, directly affect imaging. In this study, we evaluated the relationship between the effects of TE and the T_2 value of bile in the single slice method and also examined the relationship between the signal intensity of bile on T_1- and T_2-weighted images and imaging by MR cholangiography(MRC). It was difficult to image bile with high viscosities at a usual effective TE level of 700-1, 500 ms. With regard to the relationship between the signal intensity of bile and MRC imaging, all T_2 values of the bile samples showing relatively high signal intensities on the T_1-weighted images suggested high viscosities, and MRC imaging of these bile samples was poor. In conclusion, MRC imaging of bile with high viscosities was poor with the single slice method. Imaging by the single slice method alone of bile showing a relatively high signal intensity on T_1-weighted images should be avoided, and combination with other MRC sequences should be used.
