First-Year Students\u27 Satisfaction by E-Learning: Case: School of Nursing, NUMS
No full textUniversities around the world have been using electronic learning systems more and more in recent years. Due to the Covid-19 pandemic, Mongolian universities are changing the way of teaching online and thus starting from the second semester of the 2019-2020 academic year. The purpose of this study is to investigate the satisfaction of students towards e-learning and the factors affecting it.
321 first-year students of the School of Nursing of NUMS participated in this survey, the survey questionnaire filled in Google form, and received by electronically. The relationship between satisfaction and its influencing factors was evaluated by using the Pearson test (correlation coefficient).
According to the indicators of the research results, students\u27 satisfaction is the most satisfied with learning materials (4.16), student engagement (4.15), and the lowest with e-educational technology (3.25). Due to this, there is a didactic need to improve the quality of e-learning and to update the lesson technology.
Students\u27 satisfaction level had a direct strong positive correlation (r=0.65) with grade (r=0.65) and a weak direct positive correlation (r=0.38) with lesson access (p<0.001), and e-learning satisfaction scores had a direct correlation (p<0.001) to the quality of teaching, supply of learning materials, assessment, and student engagement

QR-Codes als intermediale Verknüpfungsmittel der öffentlichen Textwelt
Get PDFZusammenfassung. QR-Codes sind keine völlig neue Entwicklung, doch ist ihr Einsatz im öffentlichen Raum erst in den vergangenen Jahren in den Vordergrund getreten. Besonders die digitale Mediatisierung der Gesellschaft durch Smartphones und mobiles Internet hat die Nutzung dieser Technik für Medienunternehmen und private Nutzer deutlich interessanter gemacht. Noch ist jedoch unklar, welchen effektiven Nutzen diese Technik bringt und welche Anwendungsbereiche sinnvoll und lohnenswert für potentielle Rezipienten sind. In diesem Beitrag möchte ich sowohl auf die technische Seite von Barcode-Strukturen eingehen als auch die Gestalt des QR-Codes unter semiotisch-semantischen Gesichtspunkten erfassen und ihre Besonderheiten herausstellen. Es wird untersucht, welches Wissen erforderlich ist, um QR-Codes als Zeichen zu erkennen und erfolgreich zu nutzen, und ein Beitrag zur Verdeutlichung des Nutzungspotentials von QR-Codes als ein neuer Zeichentyp im öffentlichen Raum geleistet.Summary. QR codes are not a new phenomenon, yet their use for advertising in public spaces has become more frequent during the last years. The growing digitalization of our society, and especially smartphones and mobile internet access, have brought more attention to this technology. Nevertheless, it is still not entirely clear which applications of QR codes are really useful and for which scenarios they will become generally accepted. The contribution discusses the technical side of barcode-structures and focuses on the form of QR codes and on its semiotic aspects. It investigates how recipients understand the uses of QR codes and what kind of knowledge is needed to recognize and to successfully use them. The general aim is to understand the potential and the limits of QR codes as a new type of sign in the public space
Binäre Diskurskonstruktionen als mentale Realitäts- und Möglichkeitskonstruktionen. Exemplifiziert am ‚Dramatischen Dialog‘ des 16. bis 18. Jh.*
Get PDFZusammenfassung. Der Beitrag skizziert die Konzeption von Diskurskonstruktionen und stellt Aspekte der Analyse von zwei binären Diskurskonstruktionen vor, wer p, (der) q und wenn p, (dann/so) q. Diese binären Konstruktionen dienen dazu, Relationen zwischen Elementen auf der Basis des Konditionalschemas zu definieren, dies jedoch in unterschiedlicher Weise, nämlich als objektiv gesetzte Realität oder als zu evaluierende Möglichkeit. Die Konzeption der Diskurskonstruktionen ist angebunden an die Mental Space Theory, nach der Wissensstrukturen als Repräsentationen in mentalen Räumen integriert, selegiert, komponiert und elaboriert werden. Je nach Aufbau der Räume ergeben sich unterschiedliche inferentielle Prozesse, die auf soziale Praktiken entweder als quasi objektiv gegeben oder verhandelbar verweisen. Der kognitiv-konstruktionsgrammatische Ansatz ist verknüpft mit der philosophischen Frage, auf welche Weise das Selbst und seine Realitäten durch soziale Interaktion sichtbar werden. Binäre Diskurskonstruktionen kommen in Dramentexten des 16. bis 18. Jh. unterschiedlich häufig vor. Evidenzen aus dem literarischen Korpus stützen die theoretischen Überlegungen.Summary. This contribution explains the notion of discourse constructions, and presents aspects of the analysis of two binary discourse constructions, wer p, (der) q and wenn p, (dann/so) q. These binary constructions serve to define relations between elements on the basis of the conditional schema but in different ways, namely as an objective reality or as a possibility that needs to be evaluated, respectively. The conception of discourse constructions is related to Mental Space Theory, which considers knowledge structures as representations that are being integrated, selected, composed, and elaborated within mental spaces during interactions. Depending on the space builder, different inferences are drawn that point to social practices either as quasi objective or as negotiable. The cognitive approach of constructional grammar is combined with the philosophical question of how the self and its realities become visible through social interaction. Evidence from a corpus of 16th to 18th century drama is presented that supports the theoretical assumptions
An Energy-aware Ad-hoc Routing Strategy for Queriable Wireless Sensor Networks
Get PDFThe data volume handled by wireless sensor networks (WSN) is ever growing due to increasing node counts and node complexity – be it in traditional WSN applications or for Car2X or Internet-of-Things. Queriable WSN are a concept to handle the large data volumes in such networks by abstracting the network as a virtual database table to which users can pose queries. This declarative approach enables networks which can flexibly adapt to changing application requirements. In addition they possess a flat learning curve since users do not need to have a high technological understanding of the sensor node firmware. Upon executing a query it is first propagated through the network and once it has reached the desired nodes, results are collected and send back through the query-posing node (usually the sink). The routing which is used for the data aggregation step plays a major role in the energy efficiency in networks with increasing node and sensor value counts as represented by Car2X networks for instance. In this paper, an ad-hoc routing strategy for queriable WSN is proposed which is both energy-aware and application-specific. It will be shown that this routing can contribute greatly towards decreasing the energy consumption needed for data aggregation and thus helps increasing the network’s lifespan

The survey results showed that teachers have minimal understanding of Artificial Intelligence and its assistance in the classroom. However, they considered it as an educational possibility. The findings indicated that teachers require assistance to be effective and competent in their teaching practices; the findings suggested that AI has the potential to contribute as an assistant
Low Latency Reliable Data Sharing Mechanism for UAV Swarm Missions
Get PDFThe use of Unmanned Aerial Vehicle (UAV) swarms is increasing in many commercial applications as well as military applications (such as reconnaissance missions, search and rescue missions). Autonomous UAV swarm systems rely on multi-node interhost communication, which is used in coordination for complex tasks. Reliability and low latency in data transfer play an important role in the maintenance of UAV coordination for these tasks. In these applications, the control of UAVs is performed by autonomous software and any failure in data reception may have catastrophic consequences. On the other hand, there are lots of factors that affect communication link performance such as path loss, interference, etc. in communication technology (WIFI, 5G, etc.), transport layer protocol, network topology, and so on. Therefore, the necessity of reliable and low latency data sharing mechanisms among UAVs comes into prominence gradually. This paper examines available middleware solutions, transport layer protocols, and data serialization formats. Based on evaluation results, this research proposes a middleware concept for mobile wireless networks like UAV swarm systems

Results From Changes in The Pole of 15 kV Power Transmission Lines
Get PDFBaganuur Southeast Electricity Distribution Network 15 kV electrical transmission line interruptions research was conducted, and a factor analysis was performed to determine the conditions of the line outage. Due to the neutral grounding of the 15 kV electrical transmission line and the relatively small distance between the line wires and crossbar, there is a high incidence of grounding during the landing and flight of birds, which hurts the reliable operation and ecology of the line. Therefore, the structure of the poles changed, and the results are reflected
