The aim of this study was to validate a new paper and pencil test battery to diagnose minimal hepatic encephalopathy (MHE) in Korea. A new paper and pencil test battery was composed of number connection test-A (NCT-A), number connection test-B (NCT-B), digit span test (DST), and symbol digit modality test (SDMT). The norm of the new test was based on 315 healthy individuals between the ages of ...

To continue and expand upon the foundation provided by the recent flight of the NASA Scatterometer (NSCAT), NASA is developing the SeaWinds instrument which is scheduled to fly on the Quikscat mission in November 1998, and on the Second Japanese Earth Observation Satellite (ADEOS-11) to be launched in early 2000. In a significant design departure from previous “fan-beam” scatterometer systems, ...

Absfracf-We present a study of a matrix pencil method for estimating parameters (frequencies and damping factors) of exponentially damped and/or undamped sinusoids in noise. Comparison of this method to a polynomial method (SVD-Prony method) shows that the matrix pencil method and the polynomial method are two special cases of a matrix prediction approach but the pencil method i s more efficien...

This paper studies the problem of designing a rational Bézier developable surface pencil with a common isogeodesic, and provides an algorithm for the representation of complicated geometric models in industrial applications which need to satisfy that the shape surface can be developed and a given curve is geodesic. By employing the local Frenet orthonormal frame, the explicit expression of the ...

A model for beam customization with collimators and a range-compensating filter based on the phase-space theory for beam transport is presented for dose distribution calculation in the treatment planning of radiotherapy with protons and heavier ions. Independent handling of pencil beams in conventional pencil-beam algorithms causes unphysical collimator-height dependence in the middle of large ...

BACKGROUND Postdural puncture headache (PDPH), mainly resulting from the loss of cerebral spinal fluid (CSF), is a well-known iatrogenic complication of spinal anesthesia and diagnostic lumbar puncture. Spinal needles have been modified to minimize complications. Modifiable risk factors of PDPH mainly included needle size and needle shape. However, whether the incidence of PDPH is significantly...

Multigroup confirmatory factor analysis was applied to the responses of 4,909 employees of a multinational organization with locations in 50 countries to examine the measurement equivalence of otherwise identical Web-based and paper-and-pencil versions of 20 items comprising the transformational leadership component of Bass and Avolio’s Multifactor Leadership Questionnaire. The results supporte...

The precise relationship of functional writing and pencil grasp has not been determined. Occupational therapists and educators have long recommended the mature dynamic tripod grasp. This grasp provides the most control of the pencil. Variations of this grasp (lateral tripod, dynamic quadrupod, adapted tripod) are common in children with legible handwriting. A grasp with an open web space betwee...

abstract The theory of eigenvalues and eigenvectors of rectangular matrix pencils is complicated by the fact that arbitrarily small perturbations of the pencil can cause them disappear. However, there are applications in which the properties of the pencil ensure the existence of eigen-values and eigenvectors. In this paper it is shown how to develop a perturbation theory for such pencils. ABSTR...

The aim of the present study was to explore the ability of first-year mathematics major students to use a mathematical theorem to solve a problem through a paper-pencil and an electronic-based dynamic assessment. In this study, a convenient and purposeful sampling method was used. Thirty-five students from a public university in voluntarily participated in this study. Data gathering and analysi...
