Examining the determinants of the intention of using E-learning among university students in China During COVID-19

The main objective of the study is to examine the intention of using E-learning among university students in China. The factors such as computer experience, personal innovativeness, computer self-efficacy, and performance expectations on the impact on the intention of using e-learning during COVID-19. PLS-SEM approach is used for analyzing the research models of complex nature, where there are numerous observed and unobserved variables in the model the response rate came out 77%, which is considered more than sufficient for further analysis. An empirical study based on e-learning was conducted in a developing country. It was found by the researcher that e-learning acceptance among the users is significantly influenced by CSE. The experience of using a computer has been regarded by previous studies as a strong determinant of attitudes toward using computers. E-learning systems are used by individuals when it is perceived that it will improve their effectiveness and productivity in learning education during COVID-19. Their intentions to use e-learning systems are influenced by these beliefs. As the high rate of attrition has become a key issue in e-learning, the main concern related to online teaching and learning is motivation. Their relationship results in improved use of the e-learning system. A computer self-efficacy construct was adapted in a study based on a specific implementation of e-learning. Computer self-efficacy was defined as the level with which people feel confidence in their skills for using online technology of learning and achievement of course-related tasks. The study has highlighted an important issue related to personal innovativeness, computer experience, and personal self-efficacy among students in China during COVID-19.
Application of the Slime Mould Algorithm on the Bi-Objective Environmental Economic Dispatch Problem

This paper investigates the performance of one of the latest metaheuristic swarm-based approaches called Slime Mould Algorithm (SMA). SMA is used here to solve the static bi-objective constrained Economic Emission Dispatch (EED) problem in the presence of renewable energy sources while considering the Valve-Point Effects (VPE). The SMA approach is applied to indicate the adequate optimal solutions for operating the committed thermal units under different operational constraints. The sought optimal solutions are the midpoint between cost saving and pollutant gas emission reduction. This study also examines the influence of integrating renewable energy sources (wind and solar) into the conventional power production network. SMA technique is applied on 3- and 6-unit IEEE test systems in several case studies. The simulation numerical results indicate that SMA has a high efficiency and a better performance compared to known state-of-the-art algorithms. The proposed approach was programmed and simulated in MATLAB.
Nudging oral habits; application of behavioral economics in oral health promotion: a critical review

Background Oral health disorders significantly contribute to the global incidence of chronic diseases. Nudge interventions have demonstrated effectiveness in enhancing people’s decision-making and self-management capacities in a cost-efficient manner. As a result, these interventions could be valuable tools for fostering improved oral care habits. This critical review explores potential behavioral nudges applicable to promoting oral health. Methods A thorough electronic literature search was conducted on Scopus, Embase, and PubMed databases for papers published post-2008. The search focused on empirical evidence concerning the direct and indirect application of Nudge theory in oral health enhancement. In addition, the investigation included the nudge intervention’s role in managing common non-communicable disease risk factors (tobacco, alcohol, and sugar) and their use in other health sectors. Results and conclusion There is a dearth of studies on behavioral economics, particularly those involving reward and reminder techniques. However, various successful nudge interventions have been identified in other sectors that aim to improve health decisions. These include strategies encouraging healthier nutritional choices, tobacco and alcohol cessation, medication compliance, routine physical activity, and regular health check-ups. Such interventions can also have direct or indirect positive impacts on oral health. Implementing these interventions within an oral care framework could promote oral health due to similar underlying cognitive mechanisms. However, different types of nudge interventions have varying degrees of effectiveness. Furthermore, factors such as the method of delivery and the characteristics of the targeted population significantly influence the outcome of the intervention. Hence, it is imperative to conduct extensive studies in diverse socioeconomic settings to fully understand the potentials, limitations, and impacts of nudge interventions in promoting oral health.
Amphibians of Parque Estadual do Forno Grande, State of Espírito Santo, Southeastern Brazil: Species composition and conservation

The Brazilian Atlantic rainforest still holds a rich biodiversity despite the intense habitat loss and fragmentation. This biome is considered one of the four priority global biodiversity hotspots. We studied amphibians of the Parque Estadual do Forno Grande (PEFG), a highland remnant of Atlantic Forest Central Corridor in Espirito Santo, southeastern Brazil. The data was obtained from almost three years of sampling efforts at PEFG, records gathered from literature, and specimens housed at scientific collections. We documented a total of 31 species (30 anurans and one caecilian). According to IUCN Red List, Aplastodiscus cavicola is categorized as Near Threatened and Scinax belloni as Endangered. Megaelosia apuana is listed as Vulnerable to extinction in the state's list. The high species richness and the occurrence of threatened species reinforce the importance of protected areas for the conservation of amphibians.
Updating the Grassland Vegetation Inventory Using Change Vector Analysis and Functionally-Based Vegetation Indices

Abstract The Grassland Vegetation Inventory (GVI), which represents a comprehensive biophysical, anthropogenic, and land-use inventory of grasslands in Alberta, is widely used as a baseline for grassland conditions. An up-to-date GVI is essential for understanding grassland changes and for planning management or conservation actions on grasslands. In this study, a hybrid change detection method is proposed that incorporates change vector analysis and a set of vegetation indices (VIs) measuring different vegetation attributes for mapping the conversion of native grassland to cultivated agriculture, and ultimately to update the GVI based on multiseasonal and multiyear Landsat images. Vegetation indices that contribute significantly to differentiation between existing native grassland and land recently converted from native grassland to cultivated cropland were identified by using stepwise regression analyses and were used as inputs for mapping the conversion between 2006 and 2011 or 2015. The results showed that land conversion can be detected using a single image acquired during the growing season, but that the accuracy of identification is affected by the date of image collection and the nature of the VIs used. The greatest accuracy in detecting land conversion between 2006 and 2011 was achieved using the difference in VI between years (dVI) for the Shortwave Infrared Reflectance 3/2 Ratio (SWIR32) and the Enhanced Vegetation Difference Index (EVI) derived from July imagery (accuracy = 95.2 %; Kappa = 0.86). The same combination of SWIR32 and EVI was also effective, although with lower accuracy (accuracy = 86.0 %; Kappa = 0.64) when tested on a larger geographical area and for detecting land use change between 2006 and 2015. The method proposed here could be applied to detect the land cover conversion in other grassland regions, although the optimal VIs and image acquisition date may need to be modified depending on the type of land use activities implemented in each region.
Analyses of Paleozoic and Mesozoic brittle fractures in West-Finnmark. Geometry, kinematics and relations to structures on the Finnmark Platform in the southwestern Barents Sea

This study focuses on Paleozoic and Mesozoic brittle faults and fractures found onshore and offshore in the northwestern areas of Finnmark, the Finnmark Platform, and the southwestern Barents Sea Margin. These structures have been mapped using software for mapping (ArcGIS 10.5 & Petrel 2013) and analyzing fault-fracture lineaments and faults from bathymetry, digital elevation models, satellite images, aerial images, seismic data, and magnetic anomaly data. The main offshore features studied are the Troms Finnmark Fault Complex (TFFC), the Måsøy Fault Complex, Gjesvær Low, southern parts of Nordkapp Basin and the northern parts of Hammerfest basin. These record Mesozoic and Paleozoic faults, offsetting from the Mesozoic to the Precambrian strata. The Hammerfestand Nordkapp Basins are bounded by NE-SW and NW-SE oriented faults. The onshore areas of the study area comprises Precambrian basement rocks and Caledonian allochthons occurring as a NE-SW trending belt extending from Magerøya in the northeast to the southwest into Troms County. The foliation and basements rocks are visible affected by brittle faults and fractures. Dominant strike directions on northwestern Porsanger Peninsula are NE-SW, NW-SE and EW, while Magerøy records dominantly E-W. Directions are related to the TFFC directions. These faults and fractures manifest in outcrops, lineaments on aerial photos, DEM and bathymetry. The lineaments can be traced onshore to offshore. The landscape displays lineaments, fjords and sounds localized in high-density fracture zones, or in the core zones of major faults. The landscape indicates that there are several larger faults hidden in western Finnmark. The onshore NE-SW and E-W lineaments, faults and fractures can be compared with the offshore NE-SW to E-W faults. These NE-SW to E-W oriented faults, fractures and lineaments are related to the tensional stress from the opening of the Atlantic Ocean Margin. NW-SE oriented lineaments are presumed to be related to the Trollfjord Komagelv Fault Zone (TKFZ), which resulted in strike-slip to oblique-slip faults. The NW-SE oriented leg of TFFC is seen in the extension of TKFZ, there is debate to whether this is a segment of TKFZ, but the listric geometry of TFFC makes this impossible to figure out, as this might overprint TKFZ if it is there. The Hammerfest Basin and Nordkapp Basin in the southwest Barents Sea and the smaller rhombic pull-apart basins on the strandflat and coastal areas are both bounded by similar trending NE-SW and NW-SE trending faults and lineaments, indicating that these are related. The onshore and offshore data show a high degree of similarity, where the NE-SW to E-W striking faults both offshore and onshore exhibits dip-slip to oblique-slip shear. The NW-SE faults and lineaments with strike-slip to oblique-slip shear are related to the TKFZ.
Effect of kinetic properties of zeolites on the gas-sensing performance of zeolite-covered SnO2 sensors

ABSTRACT Zeolite additional layers coating on metal oxide surfaces to improve the selectivity and response values of the sensors are effective and widely used. The specific adsorption and diffusion of gas molecules in the zeolite are recognised to play an important role in gas sensing improvement. In this work, the adsorption and diffusion behaviours of formaldehyde and acetone in H-Y and H-A zeolites were calculated by Monte Carlo and molecular dynamics simulations. The loading of acetone is greater than formaldehyde in these two kinds of zeolites under the same temperature and pressure, and the water load is lower. The simulation results show that the effects of the nature of the guest molecule and steric hindrance of the diffusing molecule on diffusivity are significant. The diffusivity in H-A zeolite decreases by several orders of magnitude than that in H-Y zeolite However, in H-A zeolite, the internal diffusion dominates, and only the smaller diameter formaldehyde can diffuse between the pores, which is beneficial to improving the sensing properties of formaldehyde. In addition, in the competition diffusion with water molecules, formaldehyde dominates than acetone. The H-Y/SnO2 and H-A/SnO2 sensors were prepared to verify the reliability of the molecular simulations. Research highlights The adsorption and diffusion behaviour of formaldehyde and acetone in H-Y and H-A zeolites were investigated using molecular simulation. Molecular diameter mainly influences the kinetic behaviour. The sensitisation mechanism of H-Y/SnO2 sensor to acetone and H-A/SnO2 sensor to formaldehyde was proved. Focuses on the relationship between gas-sensing the performance of zeolite-covered SnO2 sensors and the adsorption.
Microstructural Geochronology of Zircon Across the Central Uplift of the Vredefort Impact Structure, South Africa

The Vredefort central uplift, or ‘dome,’ represents the erosional remnant of one of the largest (~300 km diameter) and oldest (~2.020 Ga) terrestrial impact structures. This investigation was performed to help elucidate the complexity of the shock process on zircon, incorporating various electron beam methods, including BSE and SE imaging, EBSD, CL, and EDS (mapping and semi-quantitative compositional analysis). A new shock microstructural progression in terrestrial zircon is suggested, as well as a complete structure-wide analysis of impact melt inclusions in zircon. Regional trends in the effects of shock on zircon are included. Impact melt glass inclusion compositions vary widely, from felsic to mafic inclusions, and are related to the partial melting of local minerals. This study is significant for the future study of similar impact structures on other rocky planets, and the quantification and qualification of shock conditions as recorded in zircon.
Quantifying the Restrictiveness of Theories

We propose an algorithm for quantifying the restrictiveness of economic models. Our restrictiveness measure is evaluated on simulated, hypothetical data sets that are drawn at random from a distribution that satisfies some application-dependent content restrictions, such as that people should prefer more money to less. For each such data set, we measure the extent to which the best version of the model (i.e the parameters that give the lowest crossvalidated prediction error) improves on a naive prediction rule such as guessing at random, compared to the best achievable improvement. Models that can fit almost all data well are not restrictive. We illustrate the proposed approach with two applications: using Cumulative Prospect Theory to predict certainty equivalents for lotteries, and using the Poisson Cognitive Hierarchy Model to predict the distribution of initial play in games. ∗Department of Economics, MIT †Department of Economics, U.

Improving the quality of life of diabetes mellitus patients through education on tips for being friendly with diabetes mellitus using audiovisual media

Diabetes mellitus is a chronic condition that occurs when the pancreas cannot produce enough insulin to regulate metabolism. Diabetes mellitus cannot be cured, but with good management it can prevent organ damage and failure. Diabetes mellitus has an impact on several aspects, namely: physical health aspects, psychological aspects, social aspects and environmental aspects. The aim of this research is to determine the effect of education on diabetes-friendly tips using audio-visual media on changes in the quality of life of diabetes mellitus patients. This research method is quasi-experimental. A total of 86 diabetes mellitus patients recorded in Abadijaya Village, Sukmajaya District, Depok were selected using a purposive sampling technique. The results showed that the mean value of quality of life for the audio-visual media group before was 62.26 with SD 17.583 and after 70.26 with SD 16.441. Meanwhile, the mean value of quality of life for the leaflet group before was 61.60 with SD 19.336 and after 62.21 with SD 18.252. The results of statistical tests using the independent t-test showed that the difference in quality of life scores after being given treatment between the intervention group and the control group was p value 0.035 (<0.05). There is a significant influence between education on diabetes-friendly tips using audio-visual media compared to diabetes management education using leaflets in improving the quality of life of diabetes mellitus patients. It is hoped that this research can make educational videos on tips for being friendly with diabetes mellitus as a nursing intervention standard for patients with diabetes mellitus.
Peak nasal inspiratory flow values and visual analog scale in snoring patients

Objectives: Nasal congestion is a common symptom in nasal disease. There are objective and subjective methods for the evaluation of nasal patency. Acoustic rhinometry, rhinomanometry, and peak nasal inspiratory flow (PNIF) can be counted as objective methods. In this study, the correlation between PNIF measurement and the subjective perception of nasal obstruction measured with the method of the visual analog scale (VAS), was investigated. Methods: Our study was carried out with participants who applied to Adnan Menderes University Otorhinolaryngology Clinic Snoring Polyclinic between 2021-2022 and volunteered to participate in the study. Patients with lung diseases were excluded from the study. All patients were examined in the same environment. PNIF measurements were made. For nasal obstruction, the patients were asked to indicate their VAS score, the most severe of which was 10 points. Results: The study was carried out with 92 participants. The mean age of the patients was 38±11, the mean PNIF was 128±42 L/min, and the mean VAS score was 5.2±2. When the mean distribution of PNIF values according to age, gender, BMI, smoking habits, regular sports habits, presence of rhinitis findings, and presence of septum deviation was examined, no statistically significant difference was found between the groups. There was a weak negative correlation between PNIF and VAS score values. Conclusion: PNIF is a low-cost, easy-to-use method for the objective evaluation of nasal obstruction. The VAS score can also be used for the preliminary evaluation of nasal obstruction before objective tests. We recommend using both methods together, if possible.
Robust and fast quantitative MRI for clinical deployment

Within this thesis, my work carried out in order to prepare an existing quantitative imaging method, multi-parameter mapping, for clinical use, is summarized. My tasks were to improve the motion-robustness of the acquisitions used in this protocol, and to reduce the scan time of the protocol to a clinically viable level. In order to reduce acquisition times, I investigated the use of higher parallel imaging acceleration factors, compared to those used in the protocol to date. I found that increasing the acceleration factor from 2 to 2-by-2 is a viable approach to decrease scan time, as is elliptical k-space coverage. In order to improve the robustness versus inter-scan motion, I investigated the effect of inter-scan motion on the quantitative maps derived from the protocol. I found that, while rigid-body motion correction is not sufficient in cases where a map is calculated from more than one scan, as the changes in the receive field are unaccounted for. I introduced a correction method, based on measuring the receive field for each structural scan, and showed that it improves image quality in the presence of inter-scan motion. Motion robustness was also improved by selecting a relatively motioninsensitive acquisition trajectory, from a set of clinically available trajectories. To further address the issue of intra-scan motion, I developed a novel navigator technique, based on acquiring data concurrent with gradient spoiling. Crucially, the acquisition of this navigator did not require additional scan time. I found that this navigator is sufficiently sensitive to motion, such that outlier rejection can be used to identify motion-corrupted data points. I implemented a data re-acquisition approach, based on the outlier rejection, and showed that image quality can be improved by this method.
Effects of cognitive load and different exercise intensities on perceived effort in sedentary university students: a follow up of the Cubo Fitness Test validation

Work and intellectually fatiguing environments can significantly influence the health of individuals, which is strictly bound to motor efficiency. In particular, desk workers and university students may have a sedentary lifestyle and a condition of mental fatigue caused by daily routine, which could impair motor efficiency. The assessment is a starting point for enhancing awareness of the individual’s psychophysical condition through the perception of one’s body motor efficiency, motivating to move towards improvement. This way, a submaximal test based on perceived exertion was developed (Cubo Fitness Test, CFT) and validated in previous studies. Hence, two further studies were employed to enhance the consistency and accuracy of this instrument in different conditions. The first study investigated the internal responsiveness of CFT, evaluating if mental fatigue could affect motor efficiency. The second study investigated which perceived intensity (weak, moderate, strong, or absolute maximum) could be more reliable for applying the CFT (as previous research focused the investigation only on moderate intensity). In the first investigation, participants assessed two stimuli (mental fatigue induced with a Stroop color-word task and a neutral condition based on the vision of a documentary) lasting 60 min each. The quality of psychophysical recovery (total quality recovery) and the mood state (Italian Mood State questionnaire) were evaluated before the stimuli. After the fatiguing or the neutral task, the mood state was newly assessed, together with the evaluation of the workload’s characteristics (Nasa TLX) and the CFT motor efficiency. In the second investigation, participants had to perform CFT twice for each at different intensities of Borg’s Scale of perceived exertion. Researchers successfully requested to fill out the NASA TLX questionnaire regarding the perceived workload characteristics of CFT, and the reliability of each intensity was assessed. Results seem to enhance the consistency and the accuracy of the instrument. Indeed, findings evidenced that CFT is not influenced by mental fatigue conditions typical of the intellectual work of desk workers and university students for which this test was specifically conceived. Moreover, moderate and strong perceived intensity are the most adequate conditions to assess motor efficiency in these populations.
Compact Omnidirectional Circularly Polarized Antenna via Alford Loop and Wire-Patch Structure Combination

A compact single-fed omnidirectional circularly polarized (OCP) antenna is presented. The circular polarization is obtained by combining an Alford Loop (AL) and a Wire-Patch (WP) radiating structures, which are used to generate two orthogonal E-field components. The antenna exhibits a clear right-handed circular polarization (RHCP) with a dipole-like omnidirectional radiation pattern. A prototype has been realized using two FR-4 printed circuit boards (PCBs) and experimentally tested. The measured overlapped −10 dB impedance matching and 3 dB axial ratio bandwidth is 120 MHz wide (4.9%) from 2.40 to 2.52 GHz. The measured RCHP maximum realized gain and total efficiency are 1.91 dBic and 87%, respectively. Its compact size $(0.25\lambda \times 0.25\lambda \times 0.08\lambda)$ , and its low-cost, robust, and easy-to-realize structure make this antenna suitable for IoT applications.
