By comparing this new method to the Hess screen test, we validate its applicability among 304 patients with ocular motor nerve palsy. This new method shows great assistant value as the Hess screen test in making accurate diagnosis and quantitative evaluation the severity of diplopia. Furthermore, it is more convenient and suitable for daily clinical use.展开更多

In this article, we challenge this belief by showing how interpretation concerns psychology as a whole. To do this, the authors will first consider some dominant tendencies characterising the psychological field in general, such as the ＂empiricist illusion＂ and the ＂trap of scientism＂ （Vygotsky 1999）. Moreover, they will introduce the cultural perspective in psychology, pertinent to deconstruct several assumptions regarding research within the discipline. Stemming from this approach, ＂indirect methods＂ will be presented with regard to their potential to analyse psychological phenomena both qualitatively and scientifically. They will conclude by describing a set of principles that can be implemented when doing qualitative research as to ensure the quality and the adequacy of interpretation.展开更多

Detection and evaluation are needed to determine the parameters such as the location and depth of drilling. The record of elastic wave can be gained through laying the surveying lines of the ring and ver- tical direction in the shaft lining by the elastic wave method. And specifically, through analyzing the different parameters of seismic attribute such as the velocity of high frequency reflection wave, amplitude and frequency, the abnormal range on the wall or under the wall can be forecasted. The concrete quality of shallow layer in the shaft lining can be evaluated through the velocity of surfer wave. Using the evaluating technique of comprehensive frequency and the phase feature of waveform, the basic features such as inner construction, wall back filling and failure depth of shaft lining can be interpreted from qualitatively to half quantitatively, and the interpreting section can be drawn.
