Many organizations, including government institutions and agencies, continue to increase their financial investment on information technology (IT) solutions. Despite these investments, during the global pandemic, employees and managers are either struggling or unequipped to use these tools effectively and efficiently for sustainability, competitive advantage, and decision making. Due to global pandemics, companies must harness the power of various digital channels such as big data analytics and artificial intelligence to better serve their customers and business partners. Using Information Technology Advancements to Adapt to Global Pandemics provides insights and understanding on how companies and organizations are using advances in IT to adapt to global pandemics such as COVID-19. It explores how the various IT approaches can be used for strategic purposes. Covering topics such as higher education institutions, religious organizations, and telework, this premier reference source is an essential resource for government officials, business leaders and managers, industry professionals, IT specialists, policymakers, libraries, academicians, students, and researchers.
1m Oktober 1968 trafen Klinikchefs mit Spezialisten aus dem Bereich der Hoch- schulen und der Computer-lndustrie in Reinhartshausen zusammen, urn innerhalb der raschen Entwicklung der sogenannten zweiten technischen Revolution den Trend der modernen Medizin aufzusptiren. Ais Diskussionsgrundlage dienten ausgewillllte Refe- rate. Ein tiberblick tiber den Verlauf dieser Tagung Ui.l3t es niitzlich erscheinen, die Thematik einem grol3eren Kreis zugiinglich zu machen. So haben wir uns entschlossen, die Manuskripte der Autoren zu einem Werk zusammenzuschliel3en. Die technischen Grundlagen der elektronischen Datenverarbeitung sollen dabei allerdings unbertick- sichtigt bleiben. Die Durchsicht der Beitrage mag den Eindruck erwecken, dal3 anscheinend bereits zurtickliegende Entwicklungsphasen mit phantasievollen Forderungen an die Zukunft inhomogen zusammengestellt seien. Aber es kommt uns darauf an, in der bestaunens- wert en Schnelligkeit, mit der sich eine elektronische Informationsverarbeitung - oder besser formuliert - die moderne Wissenschaft der Informatik vollzieht, den gegen- wartigen Zustand in der Medizin aufzuzeigen und in ihm an den Einzelheiten die Ten- denzen darzustellen, die sich bald aus den ursprtinglichen mechanischen Formen der Erfassung und Verarbeitung von Daten, bald aus dem Bild der Zukunft deutlicher ab- zeichnen. Wir hegen die Hoffnung, dal3 auf dieser Basis sich pragende Konzeptionen fUr die Gestaltung der Zukunft ergeben. Herrn Kollegen NORBERT EICHENSEHER danken wir fUr seine wertvolle Unter- stiltzung bei den Korrekturen und der Abfassung des Sachverzeichnisses.
Als Stahl bezeichnet man heute alle Eisenlegierungen - mit Ausnahme der nicht schmiedbaren hochkohlenstoffhaltigen Gu sorten wie Grauguli, Hartguf und Ternperguf - ohne Riicksichr auf ihre Eigenschaften. Friiher wurde als wesentliches Merkmal des Stahles die Hartbarkeit angesehen. Es gibt aber eine ganze Reihe von Stahlen, die sich nicht harten lassen, die durch das Abschrecken aus hohen Temperaturen im Gegenteil sogar weicher, zaher werden. Edelstdble werden vielfach solche Stahle genannt, die au er mit Kohlenstoff auch noch mit anderen Grundstoffen, z. B. mit Chrom, Nickel, Wolfram, Vanadin usw. legiert sind. Diese Begriffsbestim- mung ist jedoch nicht erschopfend und auch anfechtbar, Denn man wird einen reinen Kohlenstoffstahl, der sorgfaltig erzeugt und auf dem ganzen Wege der Herstellung - vom Gu bis zum Versand - immer wieder gewissenhaft gepriift worden ist, zweifellos auch zu den Edelstahlen rechnen miissen. Andererseits enthalten manchmal Massenstahle - auch als unbeabsichtigte Verunreinigungen - ge- wisse Mengen von Legierungselementen. Das Richtige wird man treffen, wenn man die bei den grofsen Hiittenwerken in grofien Mengen erzeugten billigen Stahle als .Mas- senstahle bezeichnet, die von einem Edelstahlwerk mit Sorgfalt und unter scharfster Kontrolle hergestellten Stahle dagegen als Edelstahle. Die billigen Massenstahle werden meistens nach Festigkeit ver- kauft, die Edelstahle dagegen nach dem Verwendungszweck und unter einer Markenbezeichnung.

Die Absicht, ein Buch iiber Programmieren von Ziffernrechenanlagen zu schreiben, entstand auf Grund einer Vorlesung gleichen Titels, die ich seit nunmehr sieben Jahren an der Technischen Hochschule Wien halte. Ich hatte dabei bemerkt, daB das Interesse fiir die Programmierung von Ziffernrechnern immer weitere Kreise zieht und daB es moglich ist, dieses Interesse aus einem einheitlichen Gesichtswinkel zu befriedigen. Der Zugang zur Kenntnis des Programmierens erfolgt heute iiblicher- weise mit Hille der Mathematischen Verfahrenstechnik oder von seiten der Administrativen Automation, oder schlieBlich iiber die mit tech- nischen Einzelheiten vermengte Beschreibung spezieller Maschinen. Ich bin nun der Meinung, daB man ein Buch iiber Programmieren schreiben kann, ohne auf Einzelheiten der Mathematischen Verfahrenstechnik und der Biiroautomation oder auf technische Eigenschaften spezieller Ma- schinen eingehen zu miissen, und ohne damit jewells einem Tell der Leser das Verstandnis zu erschweren. Was nach Fortlassung der ge- nannten Gebiete bleibt, ist nicht ein trockener, unverstandlicher Rest, sondern der Inbegriff aller fiir das Programmieren wesentlichen Prin- zipien. Sowohl der Naturwissenschaftler als auch der Verwaltungsfach- mann, der diese Prinzipien erfaBt hat, wird jederzeit in der Lage sein, sie seinen besonderen Aufgaben dienstbar zu machen. Kapitel A solI zeigen, welchen Platz der Rechenautomat unter den technischen Errungenschaften einnimmt und wie er dorthin gelangt ist. Besonderes Anliegen ist mir hier der geschichtliche Uberblick, well einer- seits die deutschsprachigen Biicher auf diesem Gebiet kaum historische Angaben enthalten und andererseits die anglo-amerikanische Literatur die kontinentaleuropaische Entwicklung iibergeht. - Kapitel B enthalt die Beschreibung einer gedachten Maschine TElCO in allen Einzelheiten.

Tragwerke, die besonderen Belastungen oder au13ergewohnlichen Kraft- einwirkungen ausgesetzt sind, durch die Kiihnheit ihrer Konstruktion bzw. eine nicht alltagliche Zweckbestimmung sich auszeichnen, endlich solche, die aus neuartigem, noch nicht geniigend durchforschtem Material bestehen, werden unmittelbar vor Dbergabe an den Betrieb einer amtlichen Belastungsprobe unterzogen, die in bestimmten Zeitabschnitten wiederholt wird (periodische Erprobung). In Verbindung mit den Ergebnissen einer plangema13en Dberpriifung stehen uns damit ausreichende Anhalte zur Abgabe eines zutreffenden Urteiles iiber die Giite des in Frage stehenden Bauwerkes zur Verfiigung. Die periodischen Deformationsmessungen an bereits im Betriebe stehenden Tragwerken geben wieder Aufschlu13 iiber zwischenzeitlich etwa entstandene, optisch nur schwer wahmehmbare Mangel an lebenswichtigen Traggliedern, mit deren Bestehen immer dann zu rechnen ist, wenn im Vergleiche mit den Ergebnissen voran- gegangener Proben unzulassig gro13e Deformationen auftreten. Die Wichtigkeit und Notwendigkeit solcher diagnostisch unentbehrlichen Messungen wurde schon friih erkannt. Fehldiagnosen sind allerdings nicht ausgeschlossen, besonders wenn die verschiedenen Faktoren, die das Me13ergebnis ma13geblich beeinflussen, nicht richtig gedeutet und gegeneinander abgeschatzt werden. Hier setzt die ebenso schwierige wie verantwortungsvolle Tatigkeit des mit der Priifung und Erprobung betrauten Ingenieurs ein, der daher nicht nur iiber griindliches Wissen und reiche Erfahrung, sondern dariiber hinaus auch liber gewisse technisch- diagnostische F iihigkeiten verfligen mli13te. Andernfalls besteht, wie die Erfahrung lehrt, die nicht llnbegriindete Befiirchtung, daB z. B. Rekonstruktionen angeordnet werden, die, abgesehen von den Kosten, zumindest abwegig, wenn nicht gar system widrig sein konnen.
