The importance of efficient utilization of expensive imaging equipment has been brought to full public attention by the current health care debates. In particular, the use of imaging equipments such as Computed Tomography (CT), Mammography (MG) and Magnetic Resonance Imaging (MRI) is known to contribute to the rising cost with health care. Though medical practices and research attempt to address this issue through measuring and improving imaging equipment productivity, the analysis has mainly focused on enterprise (hospital, clinical) level instead of operational (examination) level. This is due to the lack of technical data available from medical imaging. We have recently developed and implemented an enterprise wide imaging dose tracking system for Mayo Clinic which enables a comprehensive study on imaging equipment utilization. In this research, we first propose three standardized productivity metrics to study the imaging equipment productivity. Design of experiment is then conducted to identify significant factors affecting equipment productivity and utilization. The insights can be gained for medical administrators to better allocate resource and schedule resource utilization that in turn may reduce health care expenses.

Cyberforensics is a fairly new word in the technology our industry, but one that n- ertheless has immediately recognizable meaning. Although the word forensics may have its origins in formal debates using evidence, it is now most closely associated with investigation into evidence of crime. As the word cyber has become synonymous with the use of electronic technology, the word cyberforensics bears no mystery. It immediately conveys a serious and concentrated endeavor to identify the evidence of crimes or other attacks committed in cyberspace. Nevertheless, the full implications of the word are less well understood. Cyberforensic activities remain a mystery to most people, even those fully immersed in the design and operation of cyber te- nology. This book sheds light on those activities in a way that is comprehensible not only to technology professionals but also to the technology hobbyist and those simply curious about the ?eld. When I started contributing to the ?eld of cybersecurity, it was an obscure ?eld, rarely mentioned in the mainstream media. According to the FBI, by 2009 organized crime syndicates were making more money via cybercrime than in drug traf?- ing. In spite of the rise in cybercrime and the advance of sophisticated threat actors online, the cyber security profession continues to lag behind in its ability to inves- gate cybercrime and understand the root causes of cyber attacks. In the late 1990s I worked to respond to sophisticated attacks as part of the U. S.

This research presents the development and evaluation of a breath alcohol measurement device utilizing the MQ-3 alcohol sensor and an Arduino Nano-based control system. The primary objective was to design an accurate and reliable system for detecting breath alcohol concentration, with real-time feedback provided through an OLED display and an active buzzer for alerts. The device operates by measuring the alcohol concentration in the breath and converting the sensor data into parts per million (ppm). When the alcohol concentration exceeds the predefined threshold of 5% ABV, the system activates an audible alarm via the buzzer and displays the corresponding ppm value on the OLED screen. A series of tests were conducted with eight volunteers who consumed varying amounts of alcohol. The results demonstrated the system's high accuracy and responsiveness, with the ability to detect alcohol concentrations ranging from safe levels to dangerous thresholds. The device was tested multiple times to ensure consistency and minimize errors, with the final results confirming its effectiveness in providing reliable alcohol measurements. This system holds significant potential for applications in monitoring alcohol levels in drivers and individuals involved in safety-critical activities. The research underscores the importance of real-time alcohol detection systems in enhancing public safety and ensuring compliance with safety regulations.
