Abstract This paper presents a computer vision system for evaluating the quality of deburring and edge breaking on aluminum and steel blocks. This technique produces both quantitative (size) and qualitative (quality) measures of chamfering operation from images taken with an off-the-shelf camera. We demonstrate that the proposed computer vision system can detect edge chamfering geometry within a 1–2mm range. The proposed technique does not require precise calibration of the camera to the part nor specialized hardware beyond a macro lens. Off-the-shelf components and a CAD model of the original part geometry are used for calibration. We also demonstrate the effectiveness of the proposed technique on edge breaking quality control.

The Public Sphere

The discipline of communication encompasses a broad spectrum of humanistic, interpretive, and social scientific approaches to studying public deliberation. Early work engaged Habermasian theories of the public sphere, and rhetorical scholarship has foregrounded the deliberative threads running back to the discipline’s earliest history in ancient Greece. The bulk of contemporary work, however, has examined the dynamics of deliberation, particularly in the context of face-to-face discussions and dialogues in small groups. These studies have revealed the importance of narrative and dialogic exchanges during deliberation, as well as the critical role of facilitation and the maintenance of deliberative norms. Research has also assessed the practical consequences of participating in deliberation. The discipline’s practical orientation has led some scholars to seek ways to optimize deliberative designs to maximize simultaneously the quality of their decision outputs and their civic impacts on participants.

Overall Evaluation

To assist researchers to identify Environmental Microorganisms (EMs) effectively, a Multiscale CNN-CRF (MSCC) framework for the EM image segmentation is proposed in this paper. There are two parts in this framework: The first is a novel pixel-level segmentation approach, using a newly introduced Convolutional Neural Network (CNN), namely, “mU-Net-B3”, with a dense Conditional Random Field (CRF) postprocessing. The second is a VGG-16 based patch-level segmentation method with a novel “buffer” strategy, which further improves the segmentation quality of the details of the EMs. In the experiment, compared with the state-of-the-art methods on 420 EM images, the proposed MSCC method reduces the memory requirement from 355 MB to 103 MB, improves the overall evaluation indexes (Dice, Jaccard, Recall, Accuracy) from 85.24%, 77.42%, 82.27%, and 96.76% to 87.13%, 79.74%, 87.12%, and 96.91%, respectively, and reduces the volume overlap error from 22.58% to 20.26%. Therefore, the MSCC method shows great potential in the EM segmentation field.

Healthcare Interventions

Overdiagnosis and overtreatment—overuse—is gaining wide acceptance as a leading nosocomial intervention in medicine. Not only does overuse create anxiety and diminish patients’ quality of life, in some cases it causes harm to both patients and others not directly involved in clinical care. Reducing overuse begins with the recognition and acceptance of the potential for unintended harm of our best intentions. In this paper, we introduce five cases to illustrate where harm can occur as the result of well-intended healthcare interventions. With this insight, clinicians can learn to appreciate the critical role of probability-based, evidence-informed decision-making in medicine and the need to consider the outcomes for all who may be affected by their actions. Likewise, educators need to evolve medical education and medical decision-making so that it focuses on the hierarchy of evidence and that what ‘ought to work’, based on traditional pathophysiological, disease-focused reasoning, should be subordinate to what ‘does work’.

Clinical Level

Health outcomes data are a major focus of the Australian health policy debate and the national research agenda. There is general agreement that health outcomes data should be collected. Outcomes data have been shown to be a powerful stimulant to service quality at the clinical level. It is argued here that policy which places health outcomes data at the centre of resource allocation and competitive cost control strategies is likely to undermine its capacity to stimulate quality at the clinical level. Policy is needed to support the role of health outcomes data so that it is relevant to clinicians and is seen as being fundamental to quality improvement processes at the organisational level. Governments and other funding bodies require that services be accountable for the quality of their services. By using health outcomes data this quality guarantee can be based on evidence that the data are analysed routinely and, where appropriate, clinical services are modified and improved. Without this clear role for health outcomes data, they may become yet another ‘top-down’ accountability tool that has little relevance to clinicians and therefore loses its value as a stimulant to quality improvement.

National Framework

In Crossing the Quality Chasm, the Institute of Medicine (IOM) Committee on Quality of Health Care in America identified the critical role of information technology in designing a health system that produces care that is “safe, effective, patient-centered, timely, efficient, and equitable” (Committee on Quality of Health Care in America, 2001, p. 164). A subsequent IOM report contends that improved information systems are essential to a new health care delivery system that “both prevents errors and learns from them when they occur” (Committee on Data Standards for Patient Safety, 2004, p. 1). This review specifically highlights the role of informatics processes and information technology in promoting patient safety and summarizes relevant nursing research. First, the components of an informatics infrastructure for patient safety are described within the context of the national framework for delivering consumer-centric and information-rich health care and using the National Health Information Infrastructure (NHII) (Thompson & Brailer, 2004). Second, relevant nursing research is summarized; this includes research studies that contributed to the development of selected infrastructure components as well as studies specifically focused on patient safety. Third, knowledge gaps and opportunities for nursing research are identified for each main topic. The health information technologies deployed as part of the national framework must support nursing practice in a manner that enables prevention of medical errors and promotion of patient safety and contributes to the development of practice-based nursing knowledge as well as best practices for patient safety. The seminal work that has been completed to date is necessary, but not sufficient, to achieve this objective.

The role of education is to improve the quality of education, especially in producing high-quality students. High-quality students are those who are able to think critically, creatively, logically and take initiatives in responding to issues in society caused by the impact of the development of science and technology. This study aims to determine the effect of a scientific approach to students' critical thinking skills. This study is an experimental research with one group pretest-posttest design. The sample of this study consisted of one class (28 students), which was treated using a scientific approach. Critical thinking skills are measured using a test instrument and then analyzed statistically (t test). Hypothesis test results indicate that there is an effect of using a scientific approach toward students' critical thinking skills.
