| 5352 | Contributions of Healthcare 4.0 digital applications to the resilience of healthcare organizations during the COVID-19 outbreak In this paper, we examine the contributions of digital applications to the resilience of healthcare organizations during the COVID-19 outbreak. The studied applications are framed as Healthcare 4.0 (H4.0), comprising bundles of information and communication technologies used to improve operations in the health value chain. Data collection was carried out through semi-structured interviews with 10 senior managers from clinician and non-clinician departments of two large-sized Brazilian hospitals treating patients infected with SARS-CoV-2. Interviews were analyzed through content analysis, using data analysis categories related to the application focus (i.e., supply chain, patient diagnosis, patient treatment, and patient follow-up) and targeted resilience ability (i.e., monitor, anticipate, respond, and learn). Results indicate that applications oriented to supply chain and patient diagnosis contribute to all resilience abilities. Furthermore, depending on the resilience ability to be improved, different applications may be prioritized. Four research propositions for theory-testing in future studies are also presented. | N/A | 2021 | | CORD-19 |
| 5353 | Online teaching during the COVID-19 pandemic: exploring science/STEM teachers' curriculum and assessment practices in Canada The COVID-19 pandemic necessitated school closures globally, resulting in an abrupt move to online/distance teaching or emergency remote teaching (ERT). Teachers and students pivoted from face-to-face engagement to online environments, thus impacting curriculum, pedagogy, and student outcomes across a variety of disciplines. In this paper, the authors focus on science/STEM teachers’ experiences with online teaching and learning in a Canadian context during the pandemic. Qualitative and quantitative data were collected through an online questionnaire administered to 75 Grade 1–12 science/STEM teachers in a Canadian province in May–July 2020. Through the TPACK framework and self-efficacy theory, the authors explore i) curriculum planning and implementation in online settings, ii) assessment practices and their effectiveness, and iii) student outcomes, as observed by the teachers. Results indicate that teachers used a variety of platforms, and choice of platform was mainly due to user-friendliness and interactivity, or administrative decision making. Despite teachers organizing online lessons during ERT, gaps were identified in teachers’ TPACK framework and self-efficacy, thus impacting their curriculum development, pedagogical approaches, and assessment practices. In general, teaching strategies included pre-recorded videos and self-directed learning in which teachers assigned specific tasks for students to perform independently. Teachers prioritized subject content and covering curriculum objectives over creative and student-centered pedagogical approaches. Assessment techniques employed were viewed by teachers as unauthentic and generally ineffective. Moreover, teachers reported difficulties addressing student needs and abilities, resulting in challenges providing equitable and inclusive online teaching. Finally, online teaching was viewed negatively by most teachers, in terms of student engagement and outcomes. | N/A | 2022 | | CORD-19 |
| 5354 | Supporting undergraduate students' developing water literacy during a global pandemic: a longitudinal study To prepare students to address water-related challenges, undergraduate STEM education must provide them with opportunities to learn and reason about water issues. Water in Society is an introductory-level, innovative, and interdisciplinary undergraduate course offered annually at a large midwestern university. The course focuses on both disciplinary concepts and civic engagement, and is designed around a variety of interactive, research-based practices to support students’ learning, engagement with authentic data, scientific models and modeling, and collaboration and learning among peers. This study aims to evaluate, “how have student outcomes and perceptions changed over five years of the course?”. The results are based on data from students (n = 326) in five consecutive years of the course, during which time the course transitioned from a face-to-face model to fully asynchronous online model due, in part, to impacts of the COVID-19 pandemic. The particularly rapid and abrupt transition between 2020 and 2021 in response to COVID-19 led to many course changes, including modes of communication between instructors and students and opportunities for collaboration. Here, multiple measures are used to evaluate students’ learning about water concepts, model-based reasoning about socio-hydrologic systems, and perceptions of the course across all five years. By the end of each iteration of the course, students improved their knowledge of hydrologic concepts, independent of the course format or other student-level variables. However, results also show that students’ performance on complex socio-hydrologic systems modeling tasks, as well as their overall satisfaction with the course, decreased in Year 5 when the course was fully online. Results provide insight into efforts to move undergraduate STEM courses online and specific evidence of the COVID-19 pandemic’s impacts on undergraduate STEM teaching and learning about water.

| 5355 | Traditional ecological knowledge on the slope of Mount Lawu, Indonesia: all about non-rice food security As a country with rice as the staple food, the dominant traditional ecological knowledge (TEK) on food in Indonesia is rice. However, in Tawangmangu District, Central Java Province, the TEK inherited from their ancestors is about non-rice food security. This study aimed to explore how villagers pass on and practice their knowledge and beliefs in food defense based on traditional ecological knowledge. The data were collected through FGD, interviews, and field observations of traditional ceremonial processions, agricultural activities, and natural resource management. The results showed that TEK in Tawangmangu had three themes, including (1) TEK communication and inheritance through folktales on the origin of vegetables and corn, taboo words, such as the prohibition of planting rice, and the symbolic meaning of traditional rituals and offerings; (2) the people’s philosophy is reflected in their view of God, ancestors’ spirits as folktales figures, village guards’ spirits, and other living things. The folktales protagonists’ spirits are asked to provide protection, while the antagonists' spirits are asked not to interfere; and (3) natural resources sustainability involves maintaining non-rice plant commodities, terraced agricultural land management, intercropping systems, managing water resource and crop yields, and traditional houses architecture. The locals protect the forest on Mount Lawu and Pringgodani Cave as their source of life by prohibiting cutting trees and reforestation. | N/A | 2022 | | CORD-19 |

| 5358 | Ge/GaAs Based Negative Capacitance Tunnel FET Biosensor: Proposal and Sensitivity Analysis A highly sensitive, accurate, fast and power efficient biosensor is the need of the hour. Undoubtedly, dielectrically modulated (DM) tunnel FET (TFET) assures better sensitivity as compared to MOSFET biosensors in case of label-free biosensing. However, there exists immense possibilities to upgrade TFET biosensor properties through the improvement of its DC characteristics. Therefore, in this paper a ferroelectric (FE) gate oxide and a hetero material (HM) source/drain-channel based TFET is designed for biosensor applications. A FE layer of HfZrO(2) above SiO(2) gives rise to negative capacitance (NC) effect that causes voltage amplification and hence, boosts subthreshold swing (SS) and I(ON)/I(OFF) ratio. In addition, use of a low band gap material (Ge) in source and a high band gap material (GaAs) in drain-channel junctions enhances the probability of band-to-band-tunneling (BTBT) of charge carriers. Further, to introduce biomolecules, a cavity is impinged below HfZrO(2) near SiO(2) above source/channel junction that modulates BTBT as a function of charge density (N(f)) and dielectric constant (K). This paper presents a detailed comparative analysis of Ge/GaAs-NCTFET and Ge/GaAs-TFET biosensors for different K and N(f) values from which we can conclude that the incorporation of NC effect in TFET biosensors leads to enhanced sensitivity with high speed and low power consumption. | N/A | 2022 | | CORD-19 |
| 5359 | Performance Enhancement and Comparison of Graphene Field Effect Transistor Devices Coated with HMDS Layer Graphene-based devices show good transfer characteristics, which depend upon the surface morphology of the material and substrate. During fabrication of the device, the substrate morphology is disturbed inappropriately by the surface contamination. In the present study, monolayer Graphene Field Effect Transistor (GFET) has been driven with hydrophobic Hexamethyl Disilazane (HMDS) layer. The HMDS layer is dehydrated before and after the exfoliated monolayer graphene, and the electrical characteristics were measured. The transfer curve of the HMDS coated graphene device demonstrates excellent FET characteristics and prevents contamination from the atmosphere under ambient conditions. Fabrication of GFET device on the hydrophobic substrate enhances the effective ambipolar behavior. It is beginning with an excellent platform and user-friendly device for biosensing applications. | N/A | 2022 | | CORD-19 |
| 5360 | The burden of pediatric emergency departments, constipation: a systematic review BACKGROUND: Constipation constitutes an important part of emergency service applications in our country as well as all over the world. We aimed to illuminate the situation in our regional hospital regarding the increase in the emergency department density and the financial burden of applications due to constipation. METHODS: This descriptive retrospective study was conducted in a regional tertiary hospital. The medical records of all constipation-related admissions to the emergency department between 01 January 2019 and 31 December 2019 were retrospectively reviewed. The etiology of constipation, complaints, physical examination, imaging studies, treatment modalities, and health expenses costs were recorded. RESULTS: A total of 3271 patients aged 0–17 years (mean 4.24 ± 3.56 years) were included in the study. One thousand nine hundred and seventy-six (60.3%) of the patients were male, and 1295 (39.6%) of them were female. The majority of patients (n = 3107, 95%) were discharged without hospitalization. Health expenditure due to constipation was 834.626 Turkish liras. The health cost of the patients who were treated from the emergency room without hospitalization was 780.126 Turkish liras. CONCLUSIONS: In order to reduce unnecessary constipation applications and costs in emergency services, more detailed information should be given to prevent constipation during outpatient services, and dietary counseling should be provided when necessary. | N/A | 2022 | | CORD-19 |
| 5361 | The influence of air supply inlet location on the spatial-temporal distribution of bioaerosol in isolation ward under three mixed ventilation modes The outbreak of COVID-19 and the spread of infectious pathogens through bioaerosols have once again aroused widespread concern worldwide. Isolation ward is an important place to prevent the spread of infectious bioaerosols. However, infection of health care workers (HCWs) in the isolation ward often occurs, so it is urgent to carry out relevant research to reduce the cross-infection between HCWs and patients. In this paper, the temporal and spatial distribution characteristics of bioaerosols under three mixed ventilation modes in a single ward were studied, namely, upper supply side return air of Case 1 and side supply and side return ventilation are Case 2 and Case 3 respectively. The results show that the removal efficiency of bioaerosol in the ventilation mode of Case 3, in which directional airflow is formed from the air supply inlet to the release source and then to the exhaust outlet, is 46.6% and 67.7% higher than that of Case 1 and Case 2, respectively. In addition, ventilation methods based on mixed theory do not guarantee good air quality in the breathing zone (1.3m to 1.7m) of HCWs, which may increase the inhalation risk for HCWs. It is hoped that our results can provide some useful suggestions for optimizing the airflow layout of the isolation ward, reducing the risk of cross-infection, and virus elimination. | N/A | 2022 | | CORD-19 |
| 5362 | Antioxidant properties, anti- SARS-CoV-2 study, collagenase and elastase inhibition effects, anti-human lung cancer potential of some phenolic compounds Lung cancer is one of the main reasons for death worldwide.

| 5364 | Predictive modeling of surface and dimensional features of vapour-smoothened FDM parts using self-adaptive cuckoo search algorithm Despite numerous advantages of fused deposition modeling (FDM), the inherent layer-by-layer deposition behavior leads to considerable surface roughness and dimensional variability, limiting its usability for critical applications. This study has been conducted to select optimum parameters of FDM and vapour smoothing (chemical finishing) process to maximize surface finish, hardness, and dimensional accuracy. A self-adaptive cuckoo search algorithm for predictive modelling of surface and dimensional features of vapour-smoothened FDM-printed functional prototypes has been demonstrated. The chemical finishing has been performed on hip prosthesis (benchmark) using hot vapours of acetone (using dedicated experimental set-up). Based upon the selected design of experiment technique, 18 sets of experiments (with three repetitions) were performed by varying six parameters. Afterwards, a self-adaptive cuckoo search algorithm was implemented by formulating five objective functions using regression analysis to select optimum parameters. An excellent functional relationship between output and input parameters has been developed using a self-adaptive cuckoo search algorithm which has successfully found the solution to optimization issues related to different responses. The confirmatory experiments indicated a strong correlation between predicted and actual surface finish measurements, along with hardness and dimensional accuracy. | N/A | 2022 | | CORD-19 |
| 5365 | A blockchain and smart contract-based data provenance collection and storing in cloud environment Data uploading needs security and privacy in the cloud. But there are some problems like centralized provenance data (PD) collection, storage, lack of security, integrity, and more time consumption. There are methods like Rabin, Knapsack, McEliece, Elagamal, and Rivest–Shamir–Adleman for the generation of keys but it increases the encryption and decryption time and less security. Therefore, the blockchain and smart contract-based data provenance (BSCDP) Architecture is proposed for providing secure storage in the cloud environment. Initially, the fingerprint biometrics and physically uncloneable functions (PUF) have been used in verification process. The combination of PUF and fingerprint biometrics is used for secure data transmission. To protect privacy and strengthen the security, the fuzzy extractor is employed. Secondly, we use an elliptic-curve key based cyclic shift transposition cryptography algorithm for enhancing the security when sharing the key. Thirdly, we introduce the blockchain and the interplanetary file system (IPFS) for PD collection, hash computation, and storing with reduced computational overhead (CO). The integrity of data is maintained by using blockchain based secure hashing algorithm-3. By arranging fuzzy based smart contracts (FSC), the data user (DU) tracks their data. FSC is employed for tracking the history of data. The data collected is directly stored in IPFS and the DU gets a hash from IPFS to retrieve the data in the future. Finally, the data verification is done by the provenance auditor. When comparing our proposed BSCDP method with existing methods, the proposed BSCDP method achieves high security in the cloud environment for 2 K users in terms of evidence insertion time (30 ms), verification time (30 ms), response time (40 ms), total change rate (5%), CO (5.8 Kb), encryption (50 ms) and decryption time (52 ms). | N/A | 2022 | | CORD-19 |
| 5366 | Self-directed Learning Predicts Online Learning Engagement in Higher Education Mediated by Perceived Value of Knowing Learning Goals Online education has made it possible to implement the “classes suspended but learning continues” policy during the COVID-19 outbreak. However, the intangible sense of the online educational setting requires self-directed learning (SDL) and may force students to know the goals of learning that may impact their engagement. To understand the effect, based on situated expectancy-value theory, this study considered SDL as attitude and approach and constructed a research model to explore the mediating power of perceived value of knowing learning goals (PVKLG) related to participants’ online learning engagement during the COVID-19 lockdown. Data were collected from 497 higher education students in China. After the confirmatory factor analysis with structural equation modeling, the results reported that SDL attitude and approach positively predicted learning engagement mediated by PVKLG. The results suggest that only when students have a high level of PVKLG will they be able to regulate their learning process through the two types of SDL and enhance their engagement in online learning contexts during the COVID-19 lockdown. | N/A | 2022 | | CORD-19 |
| 5367 | The effect of cashless payments on the internet and mobile banking Some of the problems of cash transactions were the inconvenience of handling cash and the limited availability of banking services to facilitate cash withdrawals. The purpose of this paper is to examine the impact of cashless payments on the usage of the internet and mobile banking services in twofolds. First, the Wald test was applied to determine the short-run causal effect of the diffusion from cash to cashless payment on the internet and mobile banking. Second, the autoregressive distributed lag (ARDL) bounds test was employed to determine the long-run effect of cashless payments on the internet and mobile banking. The novelty of this study is threefold. First, this study employed the total value of cashless payments transacted per month data that were previously unavailable for time series analysis. Second, unlike studies on the intention to adopt cashless payments, internet and mobile banking, this study used data of actual transactions paid by a consumer. Third, this study established that the internet and mobile banking were delivery channels for cashless payments. | N/A | 2022 | | CORD-19 |
