Robust block copolymer mask for nanopatterning polymer films.

The formation of well-oriented cylinders with perpendicular morphology for polystyrene-b-polydimethylsiloxane (PS-PDMS) thin films was achieved by spin coating. The self-assembled PS-PDMS nanostructured thin films were used as templates for nanopatterning; the PDMS blocks can be oxidized as silicon oxy carbide microdomains, whereas the PS blocks were degenerated by a simple oxygen plasma treatment for one-step oxidization. As a result, freestanding silicon oxy carbide thin films with hexagonally packed nanochannels were directly fabricated and used as masks for pattern transfer to underlying polymeric materials by oxygen reaction ion etching (RIE) to generate topographic nanopatterns.

Measuring mobile patient safety information system success: an empirical study.

Objective: The Health Risk Reminders and Surveillance (HRRS) system was designed to deliver critical abnormal test results of severely ill patients from Laboratory, Radiology, and Pathology departments to physicians within 5 min using cell phone text messages. This paper explores the success of the HRRS system.

Method: This study employed an augmented version of the DeLone and McLean IS success model.

Improving patient safety with RFID and mobile technology.

Medical errors have become a leading cause of death, killing more people each year than AIDS or aeroplane crashes. These medical errors can be classified into five categories: poor decision making, poor communication, inadequate patient monitoring, patient misidentification, inability to respond rapidly and poor patient tracking. Employing innovative information technologies in correcting these deficiencies and meeting the Joint Commission on Accreditation of Healthcare Organistion (JCAHO) patient safety goals is the current trend in enhancing patient safety.

Pervasive Observation Medicine: The Application of RFID to Improve Patient Safety in Observation Unit of Hospital Emergency Department.

Over the past decade, observation medicine has become an important component of emergency medicine. There are several settings in which observation medicine has been useful and valuable.(1) RFID as the patient identification, not only generates the on-line laboratory data and radiology report via hand-held wireless PDA, this RFID system help physician stream-line patient admission to acute bed or ICU in the emergency department more effectively.
