E- learning during COVID-19 pandemic, faculty Perceptions, challenges, and recommendations

Introduction: E-learning is a learning system carried out through the internet using electronic devices, it is also called online education. Since the objective of e-learning is to allow students to learn and complete their courses without physically attending a traditional on-campus academic setting, it was only appropriate to use is during the COVID-19 pandemic as a preventive precaution. The preparations to use e-learning were initiated after the university’s decision to suspend on-campus lectures, which challenged the faculty members to prepare virtual lectures in a short period of time. Method: The study’s aim is to assess the perceptions of the faculty members regarding distance e-learning during the COVID-19 pandemic. The conduction of an eﬀective E-learning session depends on knowledge and preparation from faculty members. Putting into consideration that the E-learning environment is signiﬁcantly diﬀerent from that of a traditional classroom; that is why we look for their perception as key players in this process. Results: Two-thirds of the respondents were males, 69% of them were in the age group 35-54, and half of them were assistant professors from departments that had courses during the pandemic. 50% of respondents had more than10 years of experience tutoring. 41% had experience in online teaching, but 52.5% of them had only taught 1-2 online classes. Most of the respondents agree with most of the statements of the self-eﬃcacy perception while, most of them disagree with the usefulness of the e-learning
Analysis of spatial and temporal changes of RUSLE-K soil erodibility factor in semi-arid areas in two different periods by conditional simulation

ABSTRACT Soil erosion is the most important soil degradation process threatening semi-arid and arid areas. In this study, the change in the RUSLE-K soil erodibility values due to changed climatic conditions over a 10-year period was used as a tool to investigate soil erosion potential with Sequential Gaussian Simulation (SGS) method in the Mogan catchment in Turkey. For this purpose, soil erodibility values were determined for soil samples taken from the same coordinates in 2000 and 2010, and erosion susceptibility distribution maps were produced. The results showed that even though land use practices remained unchanged, soil erodibility values changed spatially and temporally, with the relationship dependent on climatic factors. More specifically, the effects of decreased precipitation, exacerbated by increased evaporation and more prolonged dry periods, made some areas in the catchment more susceptible to erosion. The vulnerability soils in the catchment increased markedly, with the area classified as subject to ‘very severe erodibility’ increasing more than threefold, from 762 ha to 2477 ha. This study has reinforced the need for ‘minimal disturbance’ land use, supplemented by monitoring that incorporates meteorological and soil test data, to minimize soil erosion and maximize the sustainability of agricultural activities in semi-arid and arid areas.
Beginnings of Developing Kinetic Scenarios of Plasma Evolution Due to Coulomb Collisions

A new logic of reducing the two-time formalism to a highly informative scenario of redistribution of plasma particles in momentum due to Coulomb collisions is reported. Based on objective plasma evolution equations following from a properly reduced full plasma description, it has a more sound foundation than that presented in the previous report on increasing the informativeness of scenarios of the phenomenon. The possibilities of adapting the approach to the further development of more informative scenarios of plasma collisional relaxation and the modelling of transport phenomena are discussed.
The influence of CaSO4.2H2O upon the hydration character of 3CaO.Al2O3

Summary This paper presents a quantitative interpretation of results of differential thermal analysis of hydration reactions at 2, 12,23 and 52°C of 3CaO.Al2O3 mixed with 0, 0·25, 2·5, 10 or 20% gypsum, and compares these with length changes obtained from the hydration of compacts of these mixtures. Estimates of the relative reaction rates from d.t. a. peak areas and measurement of length change during these reactions showed marked agreement, although interpretation had to be made with caution. It was concluded that the formation of ettringite (high sulpho-aluminate) had no direct effect upon reaction rate, but that the reactivitv of 3CaO.Al2O3 was reduced by the sorption of (SO4)2− ions on active sites of its surface. Gypsum reduces the rate of conversion of the hexagonal hydro-aluminates to the cubic hexahydrate, probably also by sorption of (SO4)2− ions, and thus is a second mechanism by which they can retard the normal hydration of 3CaO.Al2O3. The degree to which a given addition of gypsum retards the .
Evaluation of Rational Use of Antiretrovirals before the Dolutegravir Transition in Kinshasa, Democratic Republic of Congo

Background: The ultimate goal of AntiRetroViral Treatments (ART) is to achieve complete immune restoration and lasting viral suppression in the infected patient. In order to ensure the efficacy, safety and accessibility of antiretroviral drugs (ARVs), it is recommended that they should be prescribed according to national guidelines; which are evolving with the various recommendations of the World Health Organization (WHO) and the arrival of newer, more effective and safer molecules. Objective: The objective of this study was to assess the rational use of Antiretrovirals in patients treated in Kinshasa before the use of Dolutegravir within the national program in order to assess the correct use of these molecules. Methods: This work is a descriptive cross-sectional study to assess the rational use of first-line ARVs among People Living with HIV (PLHIV) in different Centers of Treatment (ATCs) in Kinshasa before the introduction of Dolutegravir. The records of patients on ARVs were randomly and rationally selected in 12 different ATCs for HIV in Kinshasa according to three centers per district in the period from June to September 2018. Information on use and consumption of ARVs, compliance with guidelines, change of therapeutic combination as well as their reasons were consulted for the present study. Results: 507 files of PLHIV were collected in the various ATCs. 274 (54.1%) were from female patients. The most represented age group was 26 to 35 years with 192 patients (37.9%). The mean duration of first-line treatment for all patients included was 16.30 ± 5.85 months. The most widely used combination of ARVs overall was TDF + 3TC + EFV at 45.4%. 305 (60.2%) PLHIV kept the same first-line treatment molecule throughout the treatment period with an average treatment duration of 12.9 ± 2.77 months. The most common combination found in this population was TDF + 3TC + EFV (69.2%). 202 (39.8%) PLHIV changed treatment molecule yet respecting the first-line combinations. The average duration of treatment for those who changed molecules was 21.43 ± 7.25 months. Before the change, 112 (55.5%) of these patients were using the ZDV + 3TC + EFV combination. After switching, 105 (52%) of the patients used the TDF + 3TC + NVP combination. The first reason for changing molecules was its unavailability (53.3%) in the ATCs. Conclusion: Although some banned molecules are still available in some treatment centers, the guidelines on first-line treatments are respected in different centers in Kinshasa.
Adaptation of the Beliefs about Well-Being Scale to the Spanish population

Título: Adaptación de la Escala de Creencias sobre el Bienestar a la población española. Resumen: El estudio de la felicidad y el bienestar está recibiendo cada vez más atención en diferentes campos. Las investigaciones recientes sobre el bienestar se han centrado en profundizar en la concepción del individuo sobre la experiencia del bienestar. McMahan y Estes (2011a) crearon una escala que evalúa las concepciones legas del bienestar en base a cuatro dimensiones: la experiencia de placer, la evitación de la experiencia negativa, el autodesarrollo y la contribución a los demás. El objetivo de este estudio fue adaptar esta escala, Beliefs about Well-Being Scale (BWBS), a la población española. La muestra estuvo formada por 1.024 participantes de la población general con un intervalo de edad entre 17 y 87 años. El análisis factorial confirmatorio da como resultado una estructura de cuatro dimensiones, similar a la escala original, aunque en la adaptación de la escala los ítems disminuyen de 16 a 12. Los resultados del análisis de fiabilidad revelan índices similares a los de la escala original. Estos resultados confirman la validez de la Escala de Creencias sobre el Bienestar con población general en un contexto cultural diferente al del estudio original. Esto permitirá realizar estudios transculturales para analizar la influencia de la cultura en la percepción del bienestar. Palabras clave: Bienestar. Felicidad. Eudaimonia. Hedonismo. Abstract: The study of happiness and well-being is receiving increased attention in different fields. Recent research into well-being has focused on delving deeper into the individual’s conception about the experience of well-being. McMahan and Estes (2011a) created a scale that assesses lay conceptions of well-being based on four dimensions: the experience of pleasure, avoidance of negative experience, self-development and contribution to others. The goal of this study was to adapt this scale, the Beliefs about Well-Being Scale (BWBS), to the Spanish population. The sample consisted of 1,024 participants from the general population ranging in age interval from 17 to 87 years old. The confirmatory factorial analysis results in a structure of four dimensions, similar to the original scale, although in the adaptation of the scale the items decrease from 16 to 12. The results of the reliability analysis reveal indexes similar to those of the original scale. These results confirm the validity of Beliefs about Well-Being Scale with general population in a cultural context different from the original study. This will allow cross-cultural studies to analyze the influence of culture in the perception of well-being.
Detection of Waxed Chestnuts using Visible and Near-Infrared Hyper-spectral Imaging

This paper presents a study that was performed for rapid and noninvasive detection of waxed chestnuts using hyper-spectral imaging. A visual near-infrared (400_1026 nm) hyper-spectral imaging system was assembled to acquire scattering images from two groups of chestnuts (waxed and non-waxed chestnuts). The spectra of the samples were extracted from the hyper-spectral images using image segmentation process. Then multiplicative scatter correction (MSC) was conducted to preprocess the original spectra. Effective wavelengths were selected to reduce the computational burden of the hyper-spectral data. Using the seven effective wavelengths that were obtained from a successive projections algorithm (SPA), three calibration algorithms were compared: partial least squares regression (PLSR), multiple linear regression (MLR) and linear discriminant analysis (LDA). The best model for discriminating between waxed and non-waxed chestnuts was found to be the MSC-SPA-MLR model.

Rock varnish record of the African Humid Period in the Lake Turkana basin of East Africa

Rock varnish is a manganiferous dark coating accreted on subaerially exposed rocks in drylands. It often contains a layered microstratigraphy that records past wetness variations. Varnish samples from latest Pleistocene and Holocene geomorphic features in the Lake Turkana basin, East Africa display a regionally replicable microstratigraphy record of Holocene millennial-scale wetness variability and a broad interval of wetter conditions during the African Humid Period (AHP). Three major wet pulses in the varnish record occurred during the generally wet interval of the early Holocene (11.5–8.5 ka) when the lake attained its maximum high stand (MHS) at 455–460 m. A >23 m drop from the MHS occurred between 8.5 and 8 ka. Subsequently two additional wet pulses occurred during the early to middle Holocene (8–5 ka) when the lake occupied its secondary high stand at 445 m. Collectively, these five wet phases represent an extended wet interval coincident with the AHP in the region. One moderate wet phase occurred during the subsequent climatic transition from the humid to arid regime (5–4.3 ka) after the lake level dropped rapidly from 445 m to <405 m. Five minor wet phases took place during the overall arid period of the late Holocene (4.3–0 ka) when the lake level oscillated below 405 m. These findings indicate that the AHP terminated rapidly around 5 ka in the Turkana basin in terms of lake level drop, but the regional shift in relative humidity from the AHP mode to its present-day condition lagged for about 700 years until 4.3 ka, hinting at a gradual phasing out in terms of moisture condition. These findings further suggest that Lake Turkana overflowed intermittently into the Nile drainage system through its topographic sill at 455–460 m during the early Holocene and has become a closed-basin lake thereafter for the past 8 ky.
Synthesis and properties of a new halogen-free flame-retardant epoxy resin curing agent

A novel intumescent flame-retardant curing agent, poly-(meta-xylylenediamine spirocyclic pentaerythritol bisphosphonate) (PMXSPB), was synthesized and subsequently characterized using Fourier transform infrared, proton nuclear magnetic resonance, and mass spectroscopies. PMXSPB was used as a flame-retardant and curing agent for preparing halogen-free flame-retarded epoxy (EP) resins. The thermal stability, mechanical properties, flame resistance, and morphology of the char layer of flame-retarded EP resins were investigated using thermogravimetric analysis, tensile and Charpy impact tests, limiting oxygen index (LOI), the UL94 test, and scanning electron microscopy, respectively. The results demonstrated that the addition of PMXSPB improved the flame resistance of EP resin composites, and the residual char ratio at 600°C was significantly increased. The flame-retarded composites filling with 3.01% phosphorus content (EP 100 g and PMXSPB 35 g) exhibited the best combination of properties, including a higher glass transition temperature (147°C), good thermal stability, an initial weight loss temperature of 269°C, and an LOI of 31.2. The vertical burning test reached the UL94 V-0 level, and the tensile and impact strengths were 51 MPa and 4.8 kJ m−2, respectively.
Bio-Mediated Soil Improvement Using Plant Derived Enzyme in Addition to Magnesium Ion

Recently, soil improvement using EICP (Enzyme-Induced Carbonate Precipitation) methods in the geotechnical and geo-environmental field has become a prominent interest worldwide. The objective of this study was to develop an improved extraction technique of crude urease from watermelon seeds in both dry and germinated conditions. Subsequently, this study also analyzed the improvement methodology of crystal polymorphs and soil bonding incorporation of various Mg2+/Ca2+ ratios. The optimization of enzyme-mediated carbonate precipitation was also investigated by Scanning Electron Microscope (SEM) and X-ray Diffraction (XRD) analysis. Results confirmed that the precipitated crystals are mainly calcite, vaterite and aragonite primarily (depending on the Mg2+/Ca2+ ratios). Therefore, to improve the bonding capacity in between the sand particles a novel improvement methodology was investigated by adding various Mg2+/Ca2+ ratios. The mechanical properties of the treated soil (Mikawa Sand, D50 = 0.870 mm) specimens were tested by unconfined compressive strength (UCS) and this confirmed the effectiveness of adding various Mg2+/Ca2+ ratios. The results of the UCS tests showed that, the lower molar ratios of Mg2+/Ca2+ can significantly improve the UCS of the specimen (up to 50%) which could be considered a significant outcome for different bio-geotechnical applications.
Factor Influencing of Telehealth Acceptance During COVID-19 Outbreak: Extending UTAUT Model

Telehealth has become an emerging technology since they offer remote healthcare services for infected patients or those who are worried about being infected. Furthermore, Telehealth can provide routine care without the risk of contracting Covid-19. Although Telehealth offers many potential benefits, the challenge was to encourage people to use them. Research related to Telehealth adoption in Indonesia is still limited, so there is still a lack of understanding regarding their behavior intentions in using Telehealth. One of the most widely used theories to explain Telehealth adoption is the Unified Theory of Acceptance and Use of Technology (UTAUT). However, doctors' opinion and computer anxiety variables have never been applied in the UTAUT model to analyze Telehealth use behavior, especially for cases in Indonesia during the Covid-19 outbreak. In addition, many researchers point out the importance of both variables in the healthcare context increasing the need for examining this feature. This paper discusses it for the first time. The survey was conducted by distributing online questionnaires via Google Docs to 118 Indonesian respondents who have used Telehealth. The results show that performance expectancy, effort expectancy, and facilitating conditions significantly affect behavior intention to use Telehealth. Social Influence is not significantly associated with behavioral intention since early adopters are considered reluctant to other views. Moreover, performance expectancy is significantly affected by doctor’s opinions and effort expectancy is strongly influenced by
A study of structure-activity relationship of PACAP

AIMS To investigate the structure-activity relation- ship of PACAP on guinea pig gallbladder by using syn- thetic PACAP/VIP hybrid peptides. METHODS We synthesized the PACAP/VIP hybrid peptides by a simultaneous multiple solid-phase pep- tide synthesizer using the Fmoc strategy. The peptides were tested on the isolated guinea pig gallbladder us- ing an improved horizontal-type organ bath. RESULTS VIP induced relaxation of gallbladder smooth muscle strips,while PACAP27 contracted them. Positions 4,5,9 and 24～26 can be replaced without significant loss in activity. [Leu~(13)]-PACAP27, a substitution in the α-helix domain,also had no signifi- cant loss in activity (P0.05). It was more potent than [Gly~8]-and [DAsp~8]-PACAP27 and could substi- tute peptides at position 21. Des-[His~1] and [Ala~6]- PACAP27 had no activity at 10~(-7) mol/L. [Gly~8]-, [DAsp~8]-,[Phe~(21)]- and [Pro~(21)]-PACAP27 at 10~(-7)mol/L were about 25% of PACAP27 at 10~(-7) mol/L (P 0.05). CONCLUSIONS In conclusion,for the physiological action of PACAP in guinea pig gallbladder,the N-termi- nal disordered region is more important than another region.
Impact of Interest Loan, Growth of Regional Gross Domestic Product, Inflation and Economic Growth on Loans at Credit Union in West Kalimantan, Indonesia

Loans or credits offered by Kopdit credit unions are a potential source of funds that need to be developed, to help accelerate the home industry and the micro and small economies. Therefore, we want to see the impact of several conditions such as the loan interest rate, GDP per capita growth, inflation rate and economic growth. Quite a number of studies have looked at the impact of interest rates, GDP growth, inflation rates and economic growth on loans or credits to banks or banking institutions. We do not look at credit or loans from banks, but on Kopdit credit unions (CU). The results of our research show that simultaneously the loan interest rate, GDP growth, inflation rate and economic growth have a strong enough influence on loans at Credit Union Credit Unions, namely 79.2454%. Partially the variable of loan interest rate, GDP growth per capita, inflation rate affects outstanding loans, while economic growth partially has no effect on outstanding loans.
Reimagining “Collaborative Exploration”—A Signature Pedagogy for Sustainability in Early Childhood Education and Care

The purpose of this article is to identify the components and features of a signature pedagogy for sustainability in early childhood education and care to respond to the call for tradition and innovation in early childhood education. Collaborative exploration is proposed as a pedagogical strategy, a relevant mode of action for sustainable practice. This is a conceptual article that recalls the origins of early childhood pedagogy and uses an exemplary empirical narrative from a recent study to illustrate collaborative exploration in an early childhood educational setting. The outlining of the key features of collaborative exploration is furthermore inspired by dialogism. This article provides an argument against mainstream understandings of pedagogical strategies for early childhood education, which are often based on instrumental program approaches, emphasizing the transmission of information in a traditional classroom setting. It is argued that practices of collaborative exploration are embodied in a way that is aligned with the tradition of child-centered early years pedagogy. Moreover, they are crucial to ensuring that all participating children are given responsive support to become members of ecologically, socially and culturally sustainable educational practices, strengthening children’s resilience and agency and inclusive education. The article’s value lies in its potential to support teachers’ thinking and practice in recognizing and articulating collaborative exploration as a signature pedagogy.
Measuring Acculturative Stress and General Self-Rated Health of Internal Migrant Students in Indonesia: Considering Social Identity Theory

Ethnic identity and national identity are aspects of social identity that bring with them pros and cons in relation to acculturative stress and individual health more generally. As a multicultural country made up of various ethnic groups, Indonesia places a high importance on the concepts of ethnic identity and national identity, and how these twinned concepts affect individuals' physical and mental health. This study aims to identify the effect of national identity and ethnic identity on acculturative stress and general self-related health. Research was conducted on 251 university students who were Indonesian internal migrants, originating from various parts of Indonesia and studying at various universities in Central Java and Yogyakarta. The results of this study show that national identity is a construct that is better able to reduce the risk of acculturative stress and moreover has a positive effect on general self-rated health. Meanwhile, ethnic identity has the opposite effect, where ethnic identity is actually closely related to acculturative stress among students who are Indonesian internal migrants. We discuss the Implications, limitations and future research directions arising from this study.
Anti-CASPR2 and Epilepsy: don’t forget to think about it

Autoimmune encephalitis (AE) is an important cause of seizures. With the discovery of highly specific neuronal-antibodies the recognition of the clinical syndrome associated with each marker is crucial to the right diagnosis and treatment regime. In this short review we summarize the importance of CASPR2 antibodies in unknown etiology seizures and its epileptogenesis.
