This paper presents computational support for the Clock Drawing Test (CDT), a simple cognitive dysfunction diagnosis tool. Despite its popularity of current use, the CDT has been administered the same way for the past three decades as a pencil-and-paper test. By making a computerized drawing test, we can understand the process of clock drawing construction(More)
Early detection of cognitive impairment can prevent or delay the progress of cognitive dysfunction. In the field of neurology, the Clock Drawing Test (CDT) is one of the most popular instruments for detecting cognitive impairment. This paper presents the development of the ClockReader system, a computerized Clock Drawing Test. The main function of the(More)
This paper introduces a new approach to dictionary-based source separation employing a learned non-linear metric. In contrast to existing parametric source separation systems, this model is able to utilize a rich dictionary of speech signals. In contrast to previous dictionary-based source separation systems, the system can utilize perceptually relevant(More)
BACKGROUND AND AIMS Inserting a nasogastric tube (NGT) in intubated patients may be difficult because they cannot follow swallowing instructions, resulting in a high rate of first-attempt failure. We introduce a simple technique for inserting an orogastric tube in an emergency department (ED). METHODS Fifty-six patients in the ED, who were intubated and(More)
In this paper, we propose a new recognition algorithm for handwritten digit recognition. This algorithm is designed to enhance the recognition accuracy of current Microsoft SDK recognizer. The algorithm recognizes the unique signature of each number by comparing curved and straight lines, and writing sequences of the stroke. Through the trial experiments,(More)

INTRODUCTION The aim of this study was to ascertain if a modified carotid sinus massage (CSM) using ultrasonography is superior to the conventional CSM for vagal tone generation. METHODS This was a prospective, crossover, clinical trial including 30 subjects with sinus rhythm. Participants were paired, and they performed 2 types of CSM to each other. To(More)
BACKGROUND Delta neutrophil index (DNI) is a new inflammatory marker and the present study aimed to evaluate the predictive value of the DNI for the presence of a perforation in elderly with acute appendicitis. METHODS This retrospective observational study was conducted on 108 consecutive elderly patients (≥65 years old) with acute appendicitis treated(More)
