To meet today’s business culture of rapid deployment of new products and processes, engineering and manufacturing personnel must utilize efficient means for process development. This paper discusses a novel approach to characterize a task driven manufacturing process. The approach utilized Response Surface Methodology (RSM) to investigate, identify, and prioritize the key process drivers and subsequently develop quantifiable methods for setting the operating levels for the process drivers to determine if the current levels of these key process drivers result in a process response value that is near optimum. The approach identifies the improved response region, generates a mathematical model of the process and specifies an operating window that would yield consistent results for each of the process drivers. A High Strength Fiber Splicing process was used to demonstrate this approach. This study led to the identification of the region that improved the process yield from 65% to 85%.

Background and Objectives: There is emphasis on systems-based practice competencies and quality improvement (QI) training in postgraduate medical education. However, we lack effective approaches to provide experiences in these areas during undergraduate medical education. To address this, we developed a novel approach to providing didactic and experiential learning experiences in QI during a third-year family medicine clerkship. Methods: We implemented and evaluated a QI curriculum combining self-directed learning with real-world experience to increase knowledge and confidence in the plan-do-study-act (PDSA) process for family medicine clerkship students. Students collaborated and presented their change ideas in a “Shark Tank” format for practice leaders at the end of their rotation. We used pre- and postcurriculum surveys to assess knowledge of and comfort with completing QI projects. Results: Three hundred eighty-nine students completed precurriculum surveys and 242 completed postcurriculum surveys. Pre- and postlearning evaluations revealed an increase in agreement or strong agreement with self-reported understanding of specific QI topic areas of 50%. Almost all (91.3%) reported feeling confident or reasonably confident in their ability to create change in health care after exposure to the curriculum, compared with 66.3% in the precurriculum survey. One-third of students (34%) reported intent to complete the Institute for Healthcare Improvement Open School curriculum in QI. Conclusions: Self-directed learning about QI, combined with practice observation, small-group discussion and presentation in a Shark Tank format was effective and engaging for learners. Students had limited preexisting knowledge of QI principles, suggesting a need for preclinical exposure to this topic. The family medicine clerkship provides an ideal environment for teaching QI.

This paper proposes a robust algorithm for the quality improvement in human silhouettes, to improve the gait recognition percentage of a person. In silhouette based gait recognition approach, the presence of incomplete and noisy silhouettes has a direct impact on recognition performance. Using blob detection, initially the incomplete silhouettes are identified. Fusion of frame difference energy image with dominant energy image of a silhouette along with a morphological filter output, preserve the kinetic and kinematic information to make incomplete silhouette into a high quality and a complete silhouette. The results prove that the resultant silhouettes are well suited for human gait recognition algorithm with improved variance. The silhouette database is taken from CASIA database.

Abstract Background The Accreditation Council for Graduate Medical Education requires each residency program to have a Program Evaluation Committee (PEC) but does not specify how the PEC should be designed. We sought to develop a PEC that promotes resident leadership and provides actionable feedback. Methods Participants were residents and faculty in the Traditional Internal Medicine residency program at Yale School of Medicine (YSM). One resident and one faculty member facilitated a 1-h structured group discussion to obtain resident feedback on each rotation. PEC co-facilitators summarized the feedback in written form, then met with faculty Firm Chiefs overseeing each rotation and with residency program leadership to discuss feedback and generate action plans. This PEC process was implemented in all inpatient and outpatient rotations over a 4-year period. Upon conclusion of the second and fourth years of the PEC initiative, surveys were sent to faculty Firm Chiefs to assess their perceptions regarding the utility of the PEC format in comparison to other, more traditional forms of programmatic feedback. PEC residents and faculty were also surveyed about their experiences as PEC participants. Results The PEC process identified many common themes across inpatient and ambulatory rotations. Positives included a high caliber of teaching by faculty, highly diverse and educational patient care experiences, and a strong emphasis on interdisciplinary care. Areas for improvement included educational curricula on various rotations, interactions between medical and non-medical services, technological issues, and workflow problems. In survey assessments, PEC members viewed the PEC process as a rewarding mentorship experience that provided residents with an opportunity to engage in quality improvement and improve facilitation skills. Firm chiefs were more likely to review and make rotation changes in response to PEC feedback than to traditional written resident evaluations but preferred to receive both forms of feedback rather than either alone Conclusions The PEC process at YSM has transformed our program’s approach to feedback delivery by engaging residents in the feedback process and providing them with mentored quality improvement and leadership experiences while generating actionable feedback for program-wide change. This has led to PEC groups evaluating additional aspects of residency education.
