The talking touchscreen: A new approach to outcomes assessment in low literacy

PSYCHO-ONCOLOGY, Issue 2 2004
Elizabeth A. Hahn
Purpose. Cancer patients who are deficient in literacy skills are particularly vulnerable to experiencing different outcomes due to disparities in care or barriers to care. Outcomes measurement in low literacy patients may provide new insight into problems previously undetected due to the challenges of completing paper-and-pencil forms. Description of study. A multimedia program was developed to provide a quality of life assessment platform that would be acceptable to patients with varying literacy skills and computer experience. One item at a time is presented on the computer touchscreen, accompanied by a recorded reading of the question. Various colors, fonts and graphic images are used to enhance visibility, and a small picture icon appears near each text element allowing patients to replay the sound as many times as they wish. Evaluation questions are presented to assess patient burden and preferences. Results. An ethnically diverse group of 126 cancer patients with a range of literacy skills and computer experience reported that the ,talking touchscreen' (TT) was easy to use, and commented on the usefulness of the multimedia approach. Clinical implications. The TT is a practical, user-friendly data acquisition method that provides greater opportunities to measure self-reported outcomes in patients with a range of literacy skills.

A Simple Tool for Teaching Flap Design with Digital Images

DERMATOLOGIC SURGERY, Issue 12 2001
Daniel Berg MD
Background. Defects created by excision or Mohs micrographic surgery must be analyzed and surgical options including flaps must be considered. Teaching flap design to dermatology trainees is often done at the bedside of the patient with the trainee describing or marking a proposed flap. Open discussion of the options in this way is sometimes unnerving for the patient. Blackboard discussions or drawings are limited in their realism. Objective. To describe a rapid, simple method using commonly available software to allow a trainee to draw and redraw a proposed flap on a digital image of the defect without the time and cost of printing. Methods. We describe a feature in the widely used presentation program Microsoft PowerPoint which can be used to draw on an imported digital image in various colors. Results. A digital photograph taken at the bedside can quickly be loaded into PowerPoint and viewed as a full-screen picture on a computer. Using an electronic pen, multiple lines can be drawn and erased on the picture, allowing surgical planning and teaching away from the bedside. Conclusion. Design and analysis of potential incision lines for a flap can be done quickly using a digital image and commonly available software, allowing a new option for teaching flap design. [source]

Photoconductivity of CaGa2S4 single crystals doped with Eu2+ and Ce3+

PHYSICA STATUS SOLIDI (C) - CURRENT TOPICS IN SOLID STATE PHYSICS, Issue 8 2006
Kazuma Hiraguri
Abstract CaGa2S4 compounds doped with rare-earth elements (REE) exhibit luminescence with various colors. The emission process between the transition levels of REE ions has ever been extensively studied. We have measured the photoconductivity (PC) to confirm the locations of the 4f ground levels of the Eu2+ and Ce3+ ions in the band gap of the host compounds of CaGa2S4 for the first time. The estimated values for Eu2+ and Ce3+ are 1.8 eV and 0.95 eV from the top of the valence band of CaGa2S4, respectively. (© 2006 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim) [source]

Color, arousal, and performance,A comparison of three experiments

COLOR RESEARCH & APPLICATION, Issue 2 2009
Rikard Küller
Abstract Three studies of the psychological and physiological effects on people of colored room interiors are described. Experiment 1 compared a colorful and a gray room, whereas in experiments 2 and 3 red and blue rooms were compared. The results indicate that the color of an interior space will have effects on many different levels. The perception of the room itself was affected, and the colors also had an impact on the emotions and physiology of those who stayed in the rooms. Strong, especially red, colors and patterns put the brain into a more excited state, sometimes to such an extent as to cause a paradoxical slowing of the heart rate. Introvert persons, as well as those already in a negative mood, became more affected than others, which caused severe changes in their performance. The series of experiments described here were among the first to be carried out in full-scale rooms painted or otherwise decorated in various colors. One practical implication is that a moderate use of good color design will serve to improve the overall mood and well-being of people. In future research more emphasis should be placed on color, as just one component in the highly complex real-life situations. © 2009 Wiley Periodicals, Inc. Col Res Appl, 34, 141,152, 2009 [source]
