Integration of the Maker Education into Teacher Training – The Digital Laboratory at Osnabrück University

Der folgende Beitrag stellt das Konzept eines universitätsweiten Digitallabors der Universität Osnabrück vor, das in seinem Aufbau an Makerspaces und Fablabs angelehnt ist, insbesondere Lehramtsstudierende bei der Entwicklung von Digitalkompetenz fördert und Impulse für die Verwirklichung innovativer Lehr- und Lernsettings liefert. Es handelt sich um einen offenen Lernort mit mehreren Räumen für selbstorganisiertes Lernen, z. B. einem Maschinenpark sowie Podcast- und Videostudios. Da in Bezug auf Kompetenzentwicklungsmodelle, die die Anbahnung von Digitalkompetenz bei angehenden Lehrer:innen modellieren, eine Forschungslücke besteht, werden derzeit auf Basis von DigComp und DigCompEdu curriculare und extracurriculare Angebote im Digitallabor konzipiert, die der Zielgruppe den intrinsisch motivierten Zugang und das Entwickeln eines sich durch Digitalkompetenz auszeichnenden Profils ermöglichen sollen. Parallel zum Lernen vor Ort vermitteln praxisvorbereitende extracurriculare Online-Selbstlernmodule grundlegendes Technikwissen, wie am Beispiel des 3D-Drucks gezeigt wird. Der curriculare Ansatz basiert auf einem didaktischen Methodenmix inkl. eines E-Portfolios. Die Lernbegleiter:innen schaffen in Anlehnung an das Cognitive Apprenticeship-Modell einen geeigneten Rahmen, um authentische Probleme mit Lebensweltbezug im Sinne situierten Lernens abzubilden und intrinsische Motivation zu erzeugen. Ziel des Digitallabors ist es, so die Anbahnung von Digitalkompetenz in die Erfahrungswelt der Lernenden zu implementieren und Transferprozesse für spätere Herausforderungen anzustossen.

Identification of symptomatic carotid artery plaque: a predictive model combining angiography with optical coherence tomography.

Symptomatic carotid artery disease is indicative of an elevated likelihood of experiencing a subsequent stroke, with the morphology of plaque and its specific features being closely linked to the risk of stroke occurrence. Our study based on the characteristics of carotid plaque assessed by optical coherence tomography (OCT), the plaque morphology evaluated by digital subtraction angiography (DSA) and clinical laboratory indicators were combined, develop a combined predictive model to identify symptomatic carotid plaque. Patients diagnosed with carotid atherosclerotic stenosis who underwent whole-brain DSA and OCT examination at the Affiliated Hospital of Jining Medical University from January 2021 to November 2023 were evaluated. Clinical features, as well as DSA and OCT plaque characteristics, were analyzed for differences between symptomatic and asymptomatic cohorts. An analysis of logistic regression was carried out to identify factors associated with the presence of symptomatic carotid plaque. A multivariate binary logistic regression equation was established with the odds ratio (OR) serving as the risk assessment parameter. The receiver operating characteristic curve was utilized to assess the combined predictive model and independent influencing factors. A total of 52 patients were included in the study (symptomatic: 44.2%, asymptomatic: 55.8%). Symptomatic carotid stenosis was significantly linked to four main factors: low-density lipoprotein-cholesterol >3.36 mmol/L [OR, 6.400; 95% confidence interval (CI), 1.067-38.402; p = 0.042], irregular plaque (OR, 6.054; 95% CI, 1.016-36.083; p = 0.048), ruptured plaque (OR, 6.077; 95% CI, 1.046-35.298; p = 0.048), and thrombus (OR, 6.773; 95% CI, 1.194-38.433; p = 0.044). The combined predictive model generated using four indicators showed good discrimination (Area Under Curve, 0.924; 95% CI, 0.815-0. 979). The p value was <0.05 with 78.26% sensitivity and 93.10% specificity. OCT is valuable in evaluating the plaque characteristics of carotid atherosclerotic stenosis. The combined predictive model comprising low-density lipoprotein-cholesterol >3.36 mmol/L, irregular plaque, ruptured plaque, and thrombus could help in the detection of symptomatic carotid plaque. Further research conducted on additional independent cohorts is necessary to confirm the clinical significance of the predictive model for symptomatic carotid plaque.

Challenges in starting to design and make together: Examining family engagement in Fab Labs: A nexus-analytical inquiry

Making in a digital fabrication laboratory (Fab Lab) using Fab Lab processes is generally challenging for novice makers, particularly for families with young children. We conducted a qualitative study on family engagement in open-ended digital fabrication activities in an informal Fab Lab setting, where families engaged in 2D/3D designing, laser cutting, and 3D printing. We observed challenging transformations when families moved from brainstorming to digital designing and, subsequently, from digital designing to machine-making a physical object. Fab Lab instructors’ work, parental approaches, and oral discussions, which were all intended to facilitate children's participation in the activities, were central in and intertwined with these transformations, and led to the engagement or disengagement of children. Through this study, we shed light on the challenges families faced and provide insights into how to reduce the complexity of digital fabrication for families who have no prior experience of it as well as into how Fab Lab instructors can help enable young children's participation in the related activities.

Micro-structural characteristics of asphalt mixture and its effect to mechanical performance based on two-stage mixing method

Conventional asphalt mixtures are prone to material separation during mixing, causing rutting, loosening, and cracking of the pavement. This study proposes a two-stage mixing method to address these problems. The theoretical asphalt film thickness is calculated, and a physical index of the mixture for aggregates with different specific surface areas is used to determine the optimal asphalt mixing ratio. The microstructural characteristics and mechanical properties of the mixtures are evaluated using digital image processing, laboratory experiments, and correlation analyses. The results show that the two-stage mixing process mixes the aggregate more thoroughly, resulting in a uniform asphalt film with sufficient contact between the asphalt particles, improving the mixture’s mechanical performance. The results of this study can be used to improve the design of asphalt mixtures and reduce the use of petroleum asphalt.

The use of digital technologies in education: the case of physics learning

The article reveals the trends in the use of digital technologies in teaching physics by summarizing scientific results over the past 20 years. To solve the problem, a bibliographic analysis of the sources of the scientometric database of the WOS was used with the involvement of the computer tool VOSviewer (for the construction and visualization of bibliographic data) as of June 2023. The tool was used to analyse publications by keywords (a network of connections is built on the basis of all keywords of given publications). Networks of connections of keywords were built according to the queries: “physics learning”, “physics education”, “physics teaching” and “technologies”, as well as “digital technologies in teaching physics”, “physics application”, “mobile physics learning”, “virtual physics laboratory”, “digital physics laboratory”, “virtual reality &amp; physics”, “augmented reality &amp; physics”. The landscape of the use of digital technologies in teaching physics is characterized by four aspects (general, technological, educational-motivational, educational-organizational). Modern trends in teaching physics are singled out: the use of environments where simulation, modelling, visualization, virtualization of physical processes, etc. are possible; increasing popularity of virtual, augmented and mixed reality tools; use of mobile applications for learning physics; using artificial intelligence to teach physics; organization of an educational environment based on mobile or online learning, where active learning methods are determined to be appropriate. The importance of developing young people's intellectual skills (computational skills, algorithmic thinking skills, modelling processes, etc.) and visual thinking for the successful mastery of various sections of physics has been confirmed. The demand for integration links between natural sciences, mathematics, engineering, and digital technologies for STEM education has been monitored. Recommendations for the training of physics teachers have been formulated.

Artificial Lift Timing and Selection Optimized With Reduced-Physics Models

_ This article, written by JPT Technology Editor Chris Carpenter, contains highlights of paper SPE 213089, “Optimizing Artificial Lift Timing and Selection Using Reduced-Physics Models,” by Hardikkumar Zalavadia, SPE, Metin Gokdemir, and Utkarsh Sinha, SPE, Xecta Digital Labs, et al. The paper has not been peer reviewed. _ The complete paper presents an artificial lift timing and selection (ALTS) methodology based on a hybrid data-driven and physics-based work flow. The proposed method predicts future unconventional reservoir inflow performance relationship (IPR) consistently and allows for continuous evaluation of ALTS scenarios in unconventional reservoirs with multiple lift types and designs. Continuous use of this process has been shown to improve production, reduce deferred production, and extend the life of lift equipment. Introduction The intent of the work flow is to maximize the positive economic impact of a well. The authors write that, to their knowledge, incumbent methods do not include the effect of subsurface performance. In the proposed approach, feedback is injected to the reservoir and a closed-loop response is obtained implicitly because of the selection of artificial lift type and operational parameters of that type. The hybrid reservoir modeling methodology is based on identifying transient well performance (TWP). The method is based on a novel formulation that combines diffusive time of flight (DTOF), succession of pseudosteady-state material balance, and transient productivity-index (PI) concepts for estimating dynamic reservoir deliverability. (Equations associated with these processes are provided in the complete paper.) This is combined with well-deliverability estimation for different artificial lift methods and their operating parameters to perform continuous nodal analysis and forecast phase rates using novel PI-based forecasting techniques. TWP Analysis This work establishes a practical method to estimate transient-well PI for every well at field scale to understand unconventional well performance. This transient PI then can be used in a variety of applications, including well forecasting, artificial lift planning, production optimization, and field development planning. The complete paper is focused primarily on using the TWP work flow for optimizing ALTS in unconventional reservoirs that is practical in its application at a field scale. Fig. 1 depicts the suggested work flow, which combines reduced-physics and data-driven methodologies to describe well performance over a series of steps. For TWP calculations, material balance is used through a sequence of pseudosteady states on the drainage volume evolution of a closed system.

Toward a digital materials mechanical testing lab

To accelerate the growth of Industry 4.0 technologies, the digitalization of mechanical testing laboratories as one of the main data-driven units of materials processing industries is introduced in this paper. The digital lab infrastructure consists of highly detailed and standard-compliant materials testing knowledge graphs for a wide range of mechanical testing processes, as well as some tools that enable the efficient ontology development and conversion of heterogeneous materials’ mechanical testing data to the machine-readable data of uniform and standardized structures. As a basis for designing such a digital lab, the mechanical testing ontology (MTO) was developed based on the ISO 23718 and ISO/IEC 21838-2 standards for the semantic representation of the mechanical testing experiments, quantities, artifacts, and report data. The trial digitalization of materials mechanical testing lab was successfully performed by utilizing the developed tools and knowledge graph of processes for converting the various experimental test data of heterogeneous structures, languages, and formats to standardized Resource Description Framework (RDF) data formats. The concepts of data storage and data sharing in data spaces were also introduced and SPARQL queries were utilized to evaluate how the introduced approach can result in the data retrieval and response to the competency questions. The proposed digital materials mechanical testing lab approach allows the industries to access lots of trustworthy and traceable mechanical testing data of other academic and industrial organizations, and subsequently organize various data-driven research for their faster and cheaper product development leading to a higher performance of products in engineering and ecological aspects.

Quality Management System in Clinical Digital Pathology Operations at a Tertiary Cancer Center

Digital pathology workflows can improve pathology operations by allowing reliable and fast retrieval of digital images, digitally reviewing pathology slides, enabling remote work and telepathology, use of computer-aided tools, and sharing of digital images for research and educational purposes. The need for quality systems is a prerequisite for successful clinical-grade digital pathology adoption and patient safety. In this article, we describe the development of a structured digital pathology laboratory quality management system (QMS) for clinical digital pathology operations at Memorial Sloan Kettering Cancer Center (MSK). This digital pathology–specific QMS development stemmed from the gaps that were identified when MSK integrated digital pathology into its clinical practice. The digital scan team in conjunction with the Department of Pathology and Laboratory Medicine quality team developed a QMS tailored to the scanning operation to support departmental and institutional needs. As a first step, systemic mapping of the digital pathology operations identified the prescan, scan, and postscan processes; instrumentation; and staffing involved in the digital pathology operation. Next, gaps identified in quality control and quality assurance measures led to the development of standard operating procedures and training material for the different roles and workflows in the process. All digital pathology–related documents were subject to regulatory review and approval by departmental leadership. The quality essentials were developed into an extensive Digital Pathology Quality Essentials framework to specifically address the needs of the growing clinical use of digital pathology technologies. Using the unique digital experience gained at MSK, we present our recommendations for QMS for large-scale digital pathology operations in clinical settings.

Low Cost PID Controller for Student Digital Control Laboratory Based on Arduino or STM32 Modules

In the teaching process, it is important that students do not carry out exercises only by computer simulations, but also that they carry out research in real time. In times of distance learning during the COVID-19 pandemic, it would be necessary to find a solution so that the students can perform such exercises individually at home. Therefore, it has become necessary to develop cheap and simple modules of digital controllers along with analog objects with adjustable order and time constants. This paper describes a low-cost proportional–integral–derivative (PID) controller for teaching students control techniques and analog control objects in real time. The PID controller is based on the cheap and widely available microcontroller modules Arduino or STM32. The advantage of this solution is that the algorithm of the digital PID controller is calculated every constant period of time. Both the solutions presented in the paper have been successfully tested by students in practice during remote learning during the COVID-19 pandemic.
