Examining the relationship between pre-service teachers’ educational technology and material development competency and their techno-pedagogical competency

Although digi tal technologies signi fy innovation and prestige, adopting such technology in teaching praxis requires deeper understanding and examination of technology integration with different variables. This s tudy examines the relationship between pre-service teachers' material development competency as a proficiency in which technology is heavily integrated into teaching activi ties and their techno-pedagogical competency. The survey method used in this s tudy had 202 pre -service teachers enrolled in an instructional technologies and material design course delivered in a Turkish s tate university. Application-based educational technology and material development competency scale and techno-pedagogical competency scale were employed. The results showed a positive relationship between both the scales . Increase in proficiency in the techno-pedagogical competency showed an increase in the pre -service teachers' proficiency in technology enhanced material development skills. Based on these findings , issues in developing pre -service teachers ' technology enhanced material development skills within the context of their techno-pedagogical competency are discussed.
Cross-Sectional Associations of Self-Reported Social/Emotional Support and Life Satisfaction with Smoking and Vaping Status in Adults

This study aimed to examine the cross-sectional association of self-reported social/emotional support and life satisfaction with smoking/vaping status in US adults. The study included 47,163 adult participants who self-reported social/emotional support, life satisfaction, and smoking/vaping status in the 2016 and 2017 BRFSS national survey data. We used multivariable weighted logistic regression models to measure the cross-sectional association of self-reported social/emotional support and life satisfaction with smoking/vaping status. Compared to never users, dual users and exclusive smokers were more likely to have low life satisfaction, with an adjusted odds ratio (aOR) = 1.770 (95% confidence interval [CI]: 1.135, 2.760) and an aOR = 1.452 (95% CI: 1.121, 1.880) respectively, especially for the age group 18–34. Exclusive cigarette smokers were more likely to have low life satisfaction compared to ex-smokers (aOR = 1.416, 95% CI: 1.095, 1.831). Exclusive cigarette smokers were more likely to have low social/emotional support (aOR = 1.193, 95% CI: 1.030, 1.381) than never users, especially those aged 65 and above. In addition, exclusive cigarette smokers were more likely to have low social/emotional support than ex-smokers, with an aOR = 1.279 (95% CI: 1.097, 1.492), which is more pronounced among the age group 18–34, as well as 65 and above. Our results suggest that life satisfaction and social/emotional support may play important roles in smoking and vaping, which should be incorporated into behavioral interventions to reduce tobacco use.
Liking Prediction Using fNIRS and Machine Learning: Comparison of Feature Extraction Methods

The fMRI method, which is generally used to detect behavioral patterns, draws attention with its expensive and impractical features. On the other hand, near infrared spectroscopy (fNIRS) method is less expensive and portable, but it is as effective as fMRI in creating a good prediction model. With this method, a model has been developed that can predict whether people like a stimulus or not, using machine learning various algorithms. A comparison was made between feature extraction methods, which was the main focus while developing the model.
Some problems with reproducing the Standard Model fields and interactions in five-dimensional warped brane world models

In the present paper we examine, from the purely theoretical point of view and in a model-independent way, the case, when matter, gauge and Higgs fields are allowed to propagate in the bulk of five-dimensional brane world models with compact extra dimension, and the Standard Model fields and their interactions are supposed to be reproduced by the corresponding zero Kaluza-Klein modes. An unexpected result is that in order to avoid possible pathological behavior in the fermion sector, it is necessary to impose constraints on the fermion field Lagrangian. In the case when the fermion zero modes are supposed to be localized at one of the branes, these constraints imply an additional relation between the vacuum profile of the Higgs field and the form of the background metric. Moreover, this relation between the vacuum profile of the Higgs field and the form of the background metric results in the exact reproduction of the gauge boson and fermion sectors of the Standard Model by the corresponding zero mode four-dimensional effective theory in all the physically relevant cases, allowed by the absence of pathologies. Meanwhile, deviations from these conditions can lead either back to pathological behavior in the fermion sector or to a variance between the resulting zero mode four-dimensional effective theory and the Standard Model, which, depending on the model at hand, may, in principle, result in constraints putting the theory out of the reach of the present day experiments.

Also, this paper examines the opinion of their internal consistency of the development process; others are Dudley’s contribution to political science, an indicator of political national development and conclusion.
Post-COVID-19 Parkinsonism and Parkinson’s Disease Pathogenesis: The Exosomal Cargo Hypothesis

Parkinson’s disease (PD) is the second most prevalent neurodegenerative disease after Alzheimer’s disease, globally. Dopaminergic neuron degeneration in substantia nigra pars compacta and aggregation of misfolded alpha-synuclein are the PD hallmarks, accompanied by motor and non-motor symptoms. Several viruses have been linked to the appearance of a post-infection parkinsonian phenotype. Coronavirus disease 2019 (COVID-19), caused by emerging severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection, has evolved from a novel pneumonia to a multifaceted syndrome with multiple clinical manifestations, among which neurological sequalae appear insidious and potentially long-lasting. Exosomes are extracellular nanovesicles bearing a complex cargo of active biomolecules and playing crucial roles in intercellular communication under pathophysiological conditions. Exosomes constitute a reliable route for misfolded protein transmission, contributing to PD pathogenesis and diagnosis. Herein, we summarize recent evidence suggesting that SARS-CoV-2 infection shares numerous clinical manifestations and inflammatory and molecular pathways with PD. We carry on hypothesizing that these similarities may be reflected in exosomal cargo modulated by the virus in correlation with disease severity. Travelling from the periphery to the brain, SARS-CoV-2-related exosomal cargo contains SARS-CoV-2 RNA, viral proteins, inflammatory mediators, and modified host proteins that could operate as promoters of neurodegenerative and neuroinflammatory cascades, potentially leading to a future parkinsonism and PD development.

Using WhatsApp During the COVID-19 Pandemic and the Emotions and Perceptions of Users

Background Social media is an integral part of daily life as people are exposed to considerable amounts of information via social media. In particular, WhatsApp is a messaging application used for sharing information and keeping in touch with individuals and groups. It is a platform considered appropriate for expressing emotions. Purpose This study analyzed a WhatsApp group of friends in Saudi Arabia and their messages regarding the coronavirus disease 2019 (COVID-19) pandemic during the first wave of infections to capture their attitudes, emotions, and perceptions related to the pandemic. We also investigated WhatsApp usage during COVID-19. Methods and Participants A quantitative exploratory study and qualitative content analysis of a sample of WhatsApp group interactions during the pandemic in Saudi Arabia were combined. Results We found that WhatsApp was used more frequently than other social media platforms for communication with family and friends. Moreover, denial was the first behavior evident at the beginning of the pandemic, followed by hope, sadness, and anxiety, and then, panic, fear, and happiness. Conclusion WhatsApp affects its users’ attitudes, perceptions, and behavior just as much as any other social media. Posts and comments shared on WhatsApp reflected different emotions, ranging from fear, anger, and sadness to hope, happiness, and pride.
Impact of Waiving Out-of-Pocket Access Fees on HIV Testing and Linkage Services in Rivers State, Nigeria

Introduction: The financial implications of accessing health services negatively impact end-users and result in the non-utilization of healthcare services in most resource-poor countries. Direct and indirect costs of access to HIV services impede the uptake and adherence to ART, thereby hindering viral suppression in these regions. Evidence showed that out-of-pocket user fee waivers effectively improve access to healthcare services and expand their utilization. The payment of out-of-pocket user fees to access HIV services in Rivers State affected linkage to ART and was consequently waived to increase uptake of HIV services. The study aimed to determine the waiver's impact on linkage to ART. Methods: descriptive trend study to determine the difference in linkage to ART services following the waiver of access fees using data collected from the HIV control program, Rivers State. Findings: There was a gradual increase in the Number of individuals who received HIV Testing Services (HTS) and received their test results (HTS_TST_POS) after the implementation of the user fee waiver, the total HTS_TST_POS during the study period was 157,525; with a mean (IQR) of 1101.57 (107, 2061) HTS_TST_POS per week. The increase occurred between the third quarter of 2019 and the second quarter of 2021, after which a decline occurred. The waiver of the out-of-pocket payments policy was announced about week 8 of 2021, after which linkage to ART consistently tethered above 90%. The weekly mean (IQR) value of linkage to ART was 98.7% (76.6%, 105.9%); and ranged between 94% to 100% within yearly quarters; there was a 100% linkage to ART throughout the year 2021. The total number of persons currently on treatment increased from 21,914 to 173,212. Conclusion: Although the evidence supporting the effectiveness of user fee waiver as an intervention is debatable, removing out-of-pocket payments to access HIV services was effective in Rivers State and significantly improved linkage to ART.
Ammonia-oxidizing archaea and ammonium concentration as drivers of nitrification in a protected freshwater lake

Nitrification rates and ammonia-oxidizer functional gene abundance were measured in the water column of Lake Lacawac, Pennsylvania, USA, a freshwater lake on a nature sanctuary that allowed an investigation with minimal human impacts. Nitrification is a 2-step process consisting of ammonia oxidation followed by nitrite oxidation. Recent studies have shown that these 2 nitrification steps may be uncoupled and respond in different ways to environmental conditions. Additionally, the relative contribution of ammonia-oxidizing archea (AOA) vs ammonia-oxidizing bacteria (AOB) to nitrification rates varies widely across aquatic systems. To determine how nitrification rates are related to environmental parameters and the ammonia-oxidizing community in a nearly pristine environment, rates and gene abundance were measured over multiple seasons where in-situ environmental conditions varied. Rates of ammonia and nitrite oxidation were measured separately and summed to calculate total nitrification rates ranging from 1 to 568 nM/d. Ammonia oxidation rates generally outpaced nitrite oxidation rates, and rates of both ammonia and nitrite oxidation were higher at depth (10 m) compared with near-surface and mid water column. Ammonia oxidation, nitrite oxidation, and total nitrification rates were all strongly, positively correlated with in-situ [NH4+] (Kendall’s τ > 0.35, p < 0.02). AOB ammonia monooxygenase (amoA) gene copy numbers were generally greater than AOA amoA. However, AOB gene copy numbers were not correlated with any ammonia oxidation or total nitrification rates, whereas AOA abundance was positively correlated with both ammonia oxidation and total nitrification rates (Kendall’s τ > 0.41, p < 0.01). A Bayesian generalized additive model, which accounted for sampling month, indicated that total nitrification rates were best explained by AOA and [NH4+]. Thus, substrate concentration and AOA likely play key roles in regulating rates of nitrification in this small, nearly pristine freshwater lake. These reported relationships between rates of ammonia and nitrite oxidation (and, thus, total nitrification), in-situ environmental parameters, and the ammonia-oxidizer community in a protected environment establish a reference for evaluating the impact of a changing environment on mesotrophic lake water quality.
Graphene Doping Technique in TIO2 for Dye-Sensitized Solar Cells Photo-Anode

This paper proposed a technique to dope graphene in Titanium dioxide (TiO2). The work focuses on avoiding the contents of carboxyl, hydroxyl or epoxy groups which is up to 55% of the Graphene Oxide (GO) alone in which enhance the conductive performance of the composite. We have characterised the composite on colour difference and voltage-current measurement (I-V Measurement) and Energy Dispersive Spectroscopy (EDS). The results of a simple eye observation for different thin films indicates a difference in colour shades due to better dispersion in TiO2/Graphene thin film. Then the dispersion of the Graphene sheets can be seen by the uniform colour change with every different ratio. Moreover, the same ratio with different composite weight in I-V measurement resulted is similar to current/voltage readings. Finally, the oxygen atomic level and weight ratio is maintained while better atomic level and weight ratio of graphene sheets and Titania was concluded which shows a higher free electron mobility.
Cell-to-Cell Interactions during Early Drosophila Oogenesis: An Ultrastructural Analysis

Drosophila oogenesis requires the subsequent growth of distinct egg chambers each containing a group of sixteen germline cells surrounded by a simple epithelium of follicle cells. The oocyte occupies a posterior position within the germ cells, thus giving a distinct asymmetry to the egg chamber. Although this disposition is critical for the formation of the anterior–posterior axis of the embryo, the interplay between somatic and germ cells during the early stages of oogenesis remains an open question. We uncover by stage 2, when the egg chambers leaved the germarium, some unique spatial interactions between the posterior follicle cells and the oocyte. These interactions are restricted to the surface of the oocyte over the centriole cluster that formed during early oogenesis. Moreover, the posterior follicle cells in front of the oocyte display a convoluted apical membrane with extensive contacts, whereas the other follicle cells have a flat apical surface without obvious surface protrusions. In addition, the germ cells located at the posterior end of the egg chamber have very elongated protrusions that come into contact with each other or with facing follicle cells. These observations point to distinct polarization events during early oogenesis supporting previous molecular data of an inherent asymmetry between the anterior and the posterior regions of the egg chambers.
Clinical Efficacy and Safety of Pulsed Dye Laser Combined with Pingyangmycin on Hyperplastic Scar after Acne

Background Acne is the most common chronic inflammatory disease of hair follicles and sebaceous glands in dermatology. Hyperplastic scar (HS), a very common sequelae of acne, is also the most common scar type in clinical practice. Objective This research analyzed the clinical effectiveness and safety of pulsed dye laser (PDL) combined with pingyangmycin (PI) in the treatment of post-acne HS. Methods One hundred and nine patients with post-acne HS admitted in June 2020 were selected and divided into a research group (n = 52) and a control group (n = 57) according to the difference in treatment methods. The efficacy, incidence of adverse reactions, skin repair, treatment comfort, and satisfaction were compared between groups. Results The total effective rate was higher in the research group compared with the control group. No statistical difference was observed between groups in the incidence of adverse reactions. The research group showed better scar repair, skin improvement, and granulation tissue maturity than the control group. And compared with the control group, the growth factor of the research group was lower, while the treatment comfort and satisfaction, psychological state, and prognosis quality of life were higher. The two groups showed no notable difference in the recurrence rate. Conclusions PDL combined with PI can effectively improve the clinical efficacy, scar repair effect, overall skin status, and treatment experience of patients and boost the psychological state and prognostic quality of life of patients, which has great clinical application prospect for the treatment of HS.

Analysis of Uplink NOMA in Cellular IoT: A Physical Layer Security Perspective

In this paper, the physical layer security of uplink non-orthogonal multiple access transmission in cellular Internet of Things is analyzed. Using the stochastic geometry model where the location of users and eavesdroppers are respectively modeled by poisson cluster process and poisson point process, reliable performance and secrecy performance are analyzed in terms of coverage probability and secrecy outage probability, taking both intra-cell interference and inter-cell interference into consideration. Moreover, average effective secrecy throughput is analyzed which comprehensively characterize the network reliable performance and secrecy performance. The analytical and simulation results show that increasing intensity of base station bring an opposite effect to reliable performance and secrecy performance, thus there exist an optimal intensity of base station that maximizes the average effective secrecy throughput. In addition, our analysis allows an optimum selection of the system parameters like the intensity of base station and wyner's code rates.
