[ASEE Conferences 2015 ASEE Annual Conference and Exposition - Seattle, Washington (2015.06.14-2015.06.17)] 2015 ASEE Annual Conference and Exposition Proceedings - A Capstone Project on Design and Development of a Digital Light Processing 3D Printer
摘要： This paper documents an undergraduate 3D printer design and development capstone project spanning multiple semesters. Recently, a team of five undergraduate mechanical and manufacturing engineering students were given the task of rebuilding a non-functional Digital Light Processing (DLP) printer which was originally designed and built at this institution. DLP process is based on curing heat sensitive resin in printing 3D objects in layers, patented by EnvisionTec. This project had been worked on two previous semesters before this team took charge and had multiple problems needed to be addressed. The project team also inherited an overheated projector as the heat source, inefficient resin box, and old resin supply. The team’s task was to fix the necessary problems with the 3D printer, make alterations to its design and equipment to increase its functionality, and get the printer to a working condition by printing a 3D part before the semester ended.

IR and Vendors: Selecting the Right Product
摘要： Choosing the right software or tools for data dissemination, dashboards, or analysis at higher education institutions (HEIs) requires numerous things and can often be bewildering. The process should be a systematic and objective assessment resulting in a decision to accept or reject (Uzoka, Akinnuwesi, Oluwole, Adekoya, & Ebbekunle, 2016). Certain pieces are required to make this objective decision including defining needs, collecting business requirements, and understanding the climate of the institution. The latter, understanding campus climate, is about feasibility and requires investigating the resources (financial, human, technology) available, politics across departments, and ethics. This chapter reviews what it takes to choose the right software product for an HEI.

Impact of Microscope-Integrated OCT on Ophthalmology Resident Performance of Anterior Segment Surgical Maneuvers in Model Eyes
摘要： PURPOSE. The integration of swept-source optical coherence tomography (SS-OCT) into the operating microscope enables real-time, tissue-level three-dimensional (3D) imaging to aid in ophthalmic microsurgery. In this prospective randomized controlled study, we evaluated the impact of SS microscope-integrated OCT (MI-OCT) on ophthalmology residents’ performance of ophthalmic microsurgical maneuvers. METHODS. Fourteen ophthalmology residents from a single institution were strati?ed by year of training and randomized to perform four anterior segment surgical maneuvers on porcine eyes with (MI-OCTt) or without intraoperative OCT guidance. Subsequently, both groups repeated the same maneuvers without MI-OCT feedback to test whether initial MI-OCT experience affected subsequent surgical performance. Finally, the MI-OCT(cid:2) group was crossed over and allowed to repeat the same maneuvers with direct MI-OCT guidance. Each resident completed a survey at the completion of the study. RESULTS. With direct MI-OCT feedback, residents demonstrated enhanced performance in depth-based anterior segment maneuvers (corneal suture passes at 50% and 90% depth and corneal laceration repair) compared with the residents operating without MI-OCT. Microscope-integrated OCTt residents continued to outperform the controls when both groups subsequently operated without MI-OCT. For clear corneal wound geometry, there was no statistically signi?cant effect of MI-OCT as applied in this study. Overall, the resident surgeons rated their subjective experience of using MI-OCT very favorably. CONCLUSIONS. Microscope-integrated OCT feedback enhances performance of ophthalmology residents in select anterior segment surgical maneuvers. Microscope-integrated OCT represents a valuable tool in the surgical education of ophthalmology residents.

[IEEE 2018 IEEE Conference on Virtual Reality and 3D User Interfaces (VR) - Tuebingen/Reutlingen, Germany (2018.3.18-2018.3.22)] 2018 IEEE Conference on Virtual Reality and 3D User Interfaces (VR) - Evaluating the Effectiveness of Head-Mounted Display Virtual Reality (HMD VR) Environment on Students' Learning for a Virtual Collaborative Engineering Assembly Task
摘要： The emerging VR social networks (e.g., Facebook Spaces, Rec Room) provide opportunities for engineering faculties to design collaborative virtual engineering their classroom instruction with HMD VR system. However, we do not how this capacity will affect students’ learning and their professional skills (e.g., communication and collaboration). The proposed study is expected to fill this research gap and will use a mixed-methods design to explore students’ performance and learning outcomes in a virtual collaborative automotive assembly task. The quantitative data will be collected from the pre-and-post task survey and the task itself. This data will be used to analyze the differences among experiment and control groups. Students’ responses to the open questions in the post-task survey will serve as triangulation and provide deep insight for the quantitative results. The study is expected to not only contribute to the research field but also benefit different stakeholders in the engineering education systems.

Augmented Reality to Localize Individual Organ in Surgical Procedure
摘要： Objectives: Augmented reality (AR) technology has become rapidly available and is suitable for various medical applications since it can provide effective visualization of intricate anatomical structures inside the human body. This paper describes the procedure to develop an AR app with Unity3D and Vuforia software development kit and publish it to a smartphone for the localization of critical tissues or organs that cannot be seen easily by the naked eye during surgery. Methods: In this study, Vuforia version 6.5 integrated with the Unity Editor was installed on a desktop computer and configured to develop the Android AR app for the visualization of internal organs. Three-dimensional segmented human organs were extracted from a computerized tomography file using Seg3D software, and overlaid on a target body surface through the developed app with an artificial marker. Results: To aid beginners in using the AR technology for medical applications, a 3D model of the thyroid and surrounding structures was created from a thyroid cancer patient’s DICOM file, and was visualized on the neck of a medical training mannequin through the developed AR app. The individual organs, including the thyroid, trachea, carotid artery, jugular vein, and esophagus were localized by the surgeon’s Android smartphone. Conclusions: Vuforia software can help even researchers, students, or surgeons who do not possess computer vision expertise to easily develop an AR app in a user-friendly manner and use it to visualize and localize critical internal organs without incision. It could allow AR technology to be extensively utilized for various medical applications.

Assessing a Virtual Laboratory in Optics As a Complement to On-Site Teaching
摘要： Contribution: There are many on-line resources available to learn about optics and photonics, but no assessment tools exist to evaluate the learning achievements. This paper presents an assessment framework whose validity has been proven on a course with over 70 engineering students. Background: There is evidence that on-line resources complement the learning experience in many engineering fields. In the context of optics and photonics, it may be worthwhile to assess the learning experience of engineering students taking a virtual lab as a complement to on-site, traditional lab. The assessment should use empiric, measurable results that demonstrates the effectiveness of the didactic innovation proposed, based on the Technology Acceptance Model. Intended Outcomes: Students using OPTILAB software are expected to be able to demonstrate their learning of optics and photonics by having a good score in the specific question about optical diffraction included in the final exam. Application Design: OPTILAB software, simulating the optical diffraction produced by different apertures, was developed. Students use OPTILAB to check, in advance, the experimental results they will obtain in the on-site lab, with various optical apertures and settings. This is expected to make the on-site lab session more efficient, minimize errors that inevitably occur when students are confronted with a new physical phenomenon, and ultimately increase the students learning experience. Findings: The marks obtained in the exercise about optics in the final exam by the experimental set (～67.3%) and control set (～49.2%) demonstrate that OPTILAB can improve students’ learning experience in optics. The findings from the survey based on the Technology Acceptance Model are also discussed.

Integrating Google Glass into simulation-based training: experiences and future directions
摘要： Background: Education experts are starting to explore the potential uses of wearable technology and augmented reality in simulation-based training. In this article, we summarize our experiences with using Google Glass in simulation-based training and discuss potential future directions with this advanced technology. Methods: Emergency medicine residents and medical students participated in a pilot study where each team captain was asked to wear Google Glass during 15 separate simulation-based training sessions. Video obtained from Google Glass was analyzed and utilized during debriefing sessions for the residents and medical students. Results: We were able to successfully integrate Google Glass into simulation-based training and debriefing. During the analysis of each recording, observations were noted about the events that transpired and this data was used to provide instructional feedback to the residents and medical students for self-reflection and appraisal. Post-exercise surveys were conducted after each simulation session and all participants noted that Google Glass did not interfere with their simulation experience. Google Glass enabled the observers to analyze the team captain’s primary visual focus during the entire simulation scenario and feedback was provided based on the data recorded. Conclusions: Wearable technologies such as Google Glass can be successfully integrated into simulation-based training exercises without disrupting the learners’ experience. Data obtained from this integration can be utilized to improve debriefing sessions and self-reflection. Future research is underway and required to evaluate other potential uses for wearable technology in simulation-based training.

The learning about imaging diagnosis technology
摘要： Objective: To investigate the learning about management of the technology (efficient use, acquisition and maintenance of imaging diagnosis equipment) in the radiology residency program of Escola Paulista de Medicina – Universidade Federal de S?o Paulo, with a view to improving the education of radiologists. Materials and Methods: Exploratory research where residents, faculty staff and tutors of the program were quantitative and qualitatively approached with Likert scale questionnaires (46), and deepening with recorded interviews (18) and categorization based upon meaning units (thematic analysis). Results: Among the participants, 66% agreed that they had the opportunity of learning about the use of radiological equipment; for 61% the program should include knowledge on the importance of acquiring equipment; and 72% emphasized the lack of learning about equipment management and maintenance. Conclusion: As the major moment in the education of specialists, the medical residency program provides residents with a favorable environment to the learning of the skills required to the future of their professional practice, but with limited emphasis on the management of the technology: efficient use, acquisition and mainly maintenance of equipment, still poorly explored. Both the investigated program and the medical residency in radiology should incorporate, whenever possible, the commitment with the training in supplementary skills related to equipment management, developing the competence of the future radiologists.

Exploring the electromagnetic spectrum with superheroes
摘要： The various radiation types that make up the electromagnetic (EM) spectrum are ubiquitous and highly significant in modern society. Detection of visible light by the eye facilitates sight, radio waves and microwaves are used in communication technologies, x-rays are used in medical imaging, and gamma rays are frequently employed in medical procedures. Although radiation plays a predominant role in daily life, many students have developed and retain misconceptions concerning EM radiation. These misconceptions could be addressed through the use of popular culture content such as superheroes in the classroom. In a number of superhero narratives, EM radiation plays a key role in the emergence or development of superpowers. In this paper, we outline three approaches for using superheroes to support the learning of the EM spectrum, and to potentially address key student misconceptions. In one approach we have designed a student worksheet based on Captain America and vita-rays, a fictional radiation type that plays a key role in his superpowers. The worksheet has been designed to instigate critical reflection on the part of the student, while allowing the student to apply their understanding of other forms of radiation.
