Implication statement

The COVID-19 pandemic has limited in-person experiences for medical students, especially in situations involving aerosol-generating procedures. We designed a video in situ simulation to orient students to critical steps in COVID-19 intubation algorithms. Small groups of students were paired virtually with facilitators (faculty and residents) and watched a video of an in situ simulation of emergency staff performing a protected intubation, with discussion points appearing on screen at discrete times. The simple design drives engagement, discussion and allows for scheduling flexibility with no risk to the learners. It can be adapted to several different scenarios or levels of training.
Integrasi Islam dan Sains: Sebuah Telaah Epistemologi

Published: April 2021

Abstrak

Pemisahan Islam dan sains berakibat pada kemunduran peradaban umat Islam, di satu sisi, dan krisis eksistensial pada sisi yang lain. Integrasi keduanya dapat mengantarkan umat Islam pada prestasi peradaban sekaligus kesempurnaan moral. Upaya Integrasi Islam dan sains telah dimulai oleh para pemikir Muslim baik melalui dewesternisasi ilmu, Islamisasi ilmu, ilmuisasi Islam, dan lain sebagainya. Berbeda dengan tulisan serius para cendekiawan muslim tersebut, tulisan ini hanya akan berupaya mendeskripsikan integrasi bangunan epistemologis Islam dengan sains melalui library research berdasar pada data kepustakaan yang terkait. Fokus tulisan ini dibatasi pada masalah sebab keterpisahan umat Islam dengan sains dan bagaimana pola keselarasan espistemologi Islam dan sains. Tulisan ini menyimpulkan dua hal. Pertama, keterpisahan Islam dengan sains lebih dikarenakan aspek historis, sosiologis, politis dan bukan karena faktor sistem ajaran. Islam sebagai sebuah ajaran yang komprehensif tidak menempatkan “ilmu agama” dan “ilmu umum” dalam posisisi diametral-paradoksial. Kedua, pola keselarasan epistemologi Islam dan sains adalah kulli-juz’i (universal-partikular). Dengan kata lain, sains merupakan salah satu bagian dari ajaran Islam dalam satu keutuhan dan kesatuan sistem yang disebut sebagai way of life (jalan hidup).

Abstract

The separation of Islam and science resulted in the decline of Muslim civilization, on the one hand, and an existential crisis on the other. The integration of fatigue can lead Muslims to achievement as well as moral perfection. Efforts to integrate Islam and science have been initiated by Muslim thinkers through the dewesternization of science, the Islamization of science, the science of Islam, and others. In contrast to the serious writings of these Muslim scholars, this paper will only attempt to describe the integration of Islamic epistemological buildings with science through library research based on related library data. The focus of this paper is on the problem of the separation of Muslims from science and how the pattern of harmony between Islamic espistemology and science. This paper concludes two things. First, the separation of Islam and science is based more on historical, sociological, political aspects and not because of the teaching system factor. Islam as a teaching includes not placing "religious knowledge" and "general science" in a diametral-paradoxical position. Second, the pattern of harmony between Islamic and scientific epistemology is kulli-juz'i (universal-particular). In other words, science is a part of Islamic teachings in a whole and unified system known as a way of life.

PERFORMANCE DES GRANDS PROJETS : DEUX LECTURES COMPORTEMENTALES
Authors: Paché Gilles , Ika Lavagnon
Published: April 2021

La question de la contre-performance des grands projets, incluant ceux relatifs aux data industrialisés et aux SI, est l’objet de nombreux débats quant à leurs réelles retombées économiques par rapport aux retombées attendues, sans toujours mentionner leurs dépassements récurrents de temps et de budget. Cette contre-performance, une sorte de rendez-vous manqué, interpelle sur ses causes. Deux principes clé, la « hiding hand » et la « planning fallacy », apportent des réponses opposées, qui témoignent d’une controverse majeure entre Albert O. Hirschman, d’un côté, Daniel Kahneman, Amos Tversky et Bent Flyvbjerg, de l’autre. L’article s’intéresse plus spécifiquement aux comportements de projets que ladite controverse met en avant, en concluant sur l’importance d’une étude approfondie de leurs enjeux au plan sociétal, et pas seulement au plan managérial.

Authors: Gustina Gustina
Published: April 2021

Astronomy was born from the needs of society, such as in agriculture and marine fields. However, many people are not familiar with astronomical phenomena, and they tend to build myths about these phenomena. Efforts to introduce astronomy need to be spread to society. Academics have introduced astronomy, but they mostly did in the school place. Adding astronomy to a broader community is done by taking moments of Car Free Day (CFD) activities, for instance, at CFD in Palembang. The event aimed to educate people about astronomical phenomena and observe the sun with a telescope and sunglasses. The community gave responses through questionnaires on a Likert scale. The society response was outstanding, with an average value of 3.53. As many as 95.83% of respondents stated that it was necessary to hold this activity again.

Hipertrigliceridemija: naujas požiūris į diagnostiką, rizikos vertinimą ir gydymą
Authors: Pudžemytė Erina , Šlapikas Rimvydas
Published: April 2021

Hipertrigliceridemija (trigliceridų (TG) koncentracijos padidėjimas kraujo plazmoje) – tai dažnas lipoproteinų apykaitos sutrikimas. TG yra pernešami chilomikronų (CM), labai mažo tankio lipoproteinų (LMTL) ir CM bei LMTL liekanų. Hipertrigliceridemiją gali sąlygoti genetiniai pokyčiai ir gretutinė patologija. TG koncentracija yra savitas trigliceridų turinčių lipoproteinų – LMTL, CM ir jų liekanų, galinčių sukelti aterosklerozinę širdies ligą, žymuo. Esant padidėjusiai TG koncentracijai, aterogeninių lipoproteinų koncentracija bei aterosklerozės rizika irgi padidėja. 1–10 proc. ūminių pankreatitų sukelia hipertrigliceridemija. Paskutinių tyrimų duomenys rodo, jog pankreatitą gali sukelti ne tik žymi, bet ir lengva bei vidutinė hipertrigliceridemija, esant kitų rizikos veiksnių. TG koncentraciją mažina antilipidiniai vaistai: fibratai, statinai, ezetimibas, PCSK-9 inhibitoriai ir omega-3 polinesočiosios riebalų rūgštys (PNRR). Dažniausiai vartojami fibratai sumažina koncentraciją 30–50 proc., bet skirtingų fibratų poveikis širdies ir kraujagyslių sistemos ligų (ŠKL) baigtims skirtingas. Omega-3 PNRR sumažina TG koncentraciją 20–50 proc., tačiau ŠKL baigčių dažnį sumažina tik didelės (4 g) išgrynintos eikozopentaeno riebalų rūgšties dozės.
MRT-Einbringung im Bestand der Uniklinik Aachen – Der Weg ist das Ziel/MRT-Delivery inside the existing University Hospital Aachen – The Journey is the Reward
Authors: Bertram Guido
Published: April 2021

Am Universitätsklinikum (UK) Aachen werden regelmäßig Großgeräte ersetzt. Der Einbringweg eines neuen, 12 Tonnen schweren Magnetresonanztomographen (MRT) führte über Bestandsdecken mit Tragfähigkeiten zwischen 2,5 kN/m² und 10 kN/m². Der etwa 75 m lange Einbringweg innerhalb des Gebäudes erforderte unter anderem den Bau einer 15 m langen mobilen Behelfsbrücke zur Querung von zwei Kernzonen. Dabei betrug die lichte Durchfahrtshöhe 2,47 m und die Nettohöhe des MRT ohne Fahrwerk 2,35 m, sodass nur wenig Platz für die Behelfskonstruktion und das Fahrwerk zur Verfügung stand. Daher wurde eine leichte Stahlbrücke entwickelt. Das Eigengewicht der Brücke durfte maximal circa 3 Tonnen betragen. Die seitlich am MRT angebrachten Schwerlastfahrwerke wurden daher auf den Untergurten der Brückenträger aufgesetzt, um das Eigengewicht und die Bauhöhe einer Fahrbahnplatte einzusparen. Die Brücke war segmentiert und wurde händisch auf-, um- und abgebaut. Außerhalb der Kernzonen bestehen die Bestandsdecken aus p-Platten mit Stegabständen von 1,80 m und lediglich 10 cm Plattendicke. Hier wurde das MRT mit seinem 2,56 m breiten Fahrwerk „huckepack“ auf einem 12 cm hohen Schwerlasttrolley mit 1,80 m Spurweite schienengeführt auf den Trägerstegen der p-Platten verfahren.
Nachweis der Tragfähigkeit von Stahlsteindecken mithilfe von Belastungsversuchen/Proof of load capacity of steel stone ceilings by means of load tests

Published: April 2021

Das ehemalige Land- und Amtsgericht in Düsseldorf soll einer neuen Nutzung zugeführt werden. Die Deckenplatten erhalten zukünftig eine höhere Ausbaulast sowie eine höhere Verkehrslast. Ziel der geplanten Umbaumaßnahme ist es, die Bausubstanz zu erhalten und die Decke für eine langfristige und nachhaltige Nutzung als Büroimmobilie nachzuweisen. Dies erfordert neue Tragfähigkeitsnachweise, weil Bestandsunterlagen nicht vorhanden sind. Mit den experimentellen Untersuchungen gelang es, bessere Erkenntnisse über die Tragreserven der Stahlsteindecken zu erkennen. Durch die Versuche war es möglich, nicht erfassbare Einflüsse der Bestandssituation auf das Tragverhalten zu beurteilen. Für die Klärung der Materialeigenschaften und des Aufbaus der Bestandsdecken wurden auch zerstörungsfreie und zerstörende Untersuchungsmethoden angewendet. Mithilfe von Belastungsversuchen, die durch rechnerische Standsicherheitsnachweise ergänzt wurden, konnte eine sehr gute Tragfähigkeit und Gebrauchstauglichkeit der Stahlsteindecken nachgewiesen werden.

Im Hinblick auf die Herstellung gewichts- und eigenschaftsangepasster Bauteile wird die Umformtechnik vor neue Herausforderungen gestellt. Der Trend einer steigenden Variantenvielfalt fordert zudem individualisierte Komponenten und damit auch flexible Fertigungsprozesse. Dafür wird eine neue Fertigungstechnologie, die inkrementelle Blechmassivumformung (iBMU), vorgestellt. Die lokale Einstellung der Werkstückkontur, der Blechstärke und der Kaltverfestigung anhand individueller Vorgaben kennzeichnen die wesentlichen Möglichkeiten dieses Verfahrens.

 

A new forming class called incremental sheet-bulk metal forming (iSBMF) has been established in order to fulfill future economic and ecological requirements, particularly in the automotive sector. Furthermore, within the trend of individualization, a flexibility of manufacturing processes is necessary for a high product variety. The local setting of the workpiece contour, the sheet thickness and the strain hardening based on individual requirements are the most important advantages provided by this incremental approach.

Zur Massereduktion und Erhöhung der spezifischen Steifigkeit einer Portalfräsmaschine wird die Gestalt des Maschinenschlittens verbessert und ein Materialwechsel der Strukturbauteile des Schlittens von Aluminium zu Faser-Kunststoff-Verbunden durchgeführt. Um einen starken Anstieg der Fertigungskosten zu vermeiden, wird in Differentialbauweise aus verklebten CFK-Halbzeugplatten konstruiert. Die Laminatauslegung der Bauteile erfolgt in Anlehnung an die Netztheorie unter Berücksichtigung der Hauptspannungen und deren Richtungen. Mithilfe der Gestaltänderung und des Materialwechsels wird für den Schlitten bei einer Massereduktion von einem Drittel die spezifische Steifigkeit um den Faktor 2,5 verbessert.

 

In order to pursue mass reduction and furthermore to increase the specific stiffness at the same time, the tool’s slide of a portal milling machine is redesigned. In this process, not only the shape was modified but also a change of material towards composites was performed. To prevent rise in manufacturing costs, the specific design is carried out using the differential design method considering bonded semi-finished sheets. The layout of laminates is inspired by the net theory, taking value and direction of the main tensions into account. The performed redesign leads to one third mass reduction and a 2.5-fold increase in the specific stiffness of the tool’s slide.

Published: April 2021

The present study aims to identify the five major factors of personality and their relationship to meta-motivation among university students. The two researchers used the correlational descriptive approach, and the study population consisted of 5260 male and female students pursuing a bachelor's degree from Palestine Technical University. The two researchers chose the sample by a simple random method, which consisted of 377 students split between 133 males and 244 females. The results showed that the extraversion factor, one of the five major personality factors, is the most prevalent factor among students of Palestine Technical University, whereas the neurotic factor is the least prevalent factor. They also showed a direct correlation between the five major factors (extraversion, openness, conscientiousness and all dimensions of meta-motivation), the existence of an inverse correlation between the neurotic factor and all dimensions of meta-motivation and the absence of a correlation between the compatibility factor and all dimensions of meta-motivation. The study recommends conducting field studies to enhance meta-motivation among university students while depending on the five major personality factors and forming the ideal personality for a university student.

Company YS participates in managing the natural gas network by creating a Metering Regulating System (MRS), which is a tool to measure gas usage and damage to the natural gas network. Based on the data obtained, the MRS delivery process was often not in accordance with the agreed schedule, there was a delay of up to 46%, namely 50 days late from the planned schedule. To overcome these delays, waste reduction is carried out by mapping the overall condition of the company in Value Stream Mapping (VSM) and mapping in detail with the Value Stream Mapping Analysis Tools (VALSAT). In the VSM method, a Current Value Stream Mapping is carried out which then identifies the waste in which the correlation score between the wastes is described in a matrix called the Waste Relationship Matrix then followed by the calculation of the Waste Assessment Questionnaire. Then in the VALSAT method, further waste identification was carried out using seven tools. The most influential percentage of waste that has been obtained is then searched for the root cause using a fishbone diagram and then eliminated and depicted in the Future Value Stream Mapping. The most influential waste in the fabrication process is Waiting and after repairs according to the recommendations, the lead time is obtained from 41,822.60 minutes or 99 working days to 35,055.60 minutes or 83 working days so that the fabrication process can be completed 3 days faster than scheduled.
