Published: April 2024

Evaluating an information system for success is key. Evaluating success factors of a Learning Management System (LMS) is essential in perspective of information systems success in a developing country context. eLearning is vital to educational system considering its benefits and impacts, particularly in accessing learning from remote areas, suitable for different learners’ categories, minimal resource utilization in terms of cost and time. Through the literature reviewed on eLearning and Information System, the desire to determine the variables that measure the success factors for information systems continues. Existing Information System (IS) success models do not sufficiently evaluate eLearning in developing country, Uganda inclusive as the current IS success models are generic in nature. This study aimed to describe a model of information system success tailored to eLearning system, Kampala International University as a case study, a Uganda’s context. To address the above objective, a field study was conducted, using questionnaire to determine factors for information systems success in Uganda, a sample size of 370 respondents were used from population size of 5500 using Sloven formula. The respondents comprise of 340 students, 27 lecturers and 4 administrators. The identified success factors are skills & training, infrastructure and management support. Data were cleaned and analyzed using Statistical Package for Social Scientists version 20.0 (SPSS). This study adopted Delone and Mclean’s Information System Success model (2016) and extended it using factors obtained from the field study survey. Analysis was performed to evaluate the model. Results of the study showed that all the independent variables management support, infrastructure, skills and training are positively related to the dependent variable of intention to and use of information system. There exists a strong relationship between the multiple independent variables and the dependent variable. All factors identified, has positive impact in explaining the variation in intention to use and use of the system with r coefficient of 0.343, 0.406 and 0.406 respectively. The results of the study presented a model of success factors for Learning Management System, eLearning specifically. For future research, this study recommends conducting qualitative studies to delve deeper into the nuanced perceptions and experiences of learners and teachers as well as looking into policies that can promote eLearning especially in developing countries.

La realización del presente trabajo está orientado a investigar la relación entre el aprendizaje del idioma quechua y el silabo de la asignatura de taller de quechua o lengua nativa en los estudiantes de los primeros ciclos de la Escuela profesional de Administración de la Universidad andina del cusco filial Sicuani.
En tal sentido se planteó una investigación de tipo cuantitativo, haciendo uso del diseño correlacional; se requirió de conceptos teóricos puntuales sobre aprendizaje y silabo, para luego aplicar como instrumentos de recojo de información y de medición; una prueba escrita que permitió medir el nivel de aprendizaje de los estudiantes de los primeros ciclos en la escuela profesional de Administración y una guía de observación instrumento que permitió al estudiante situarse de manera sistemática observar la estructura del silabo de la asignatura con el desarrollo de temas y temáticas incluidas en el silabo, para ello se consideró un grupo de 32 estudiantes.
            Si bien estadísticamente existe una correlación entre ambas variables que alcanza a 0.350 con un p-value de 0.049, concluimos que dicha relación no es significativa porque los factores del silabo que influyen son más informativos que sustanciales en la formación de los estudiantes. Por ello recomendamos replicar esta investigación en otras carreras profesionales y revisar los contenidos del sílabo para mejorarlo y hacer que sean significativos en la formación profesional.

Authors: Ore Garvan Claudia Clara , Valdivia Holguin Claudia Isabel , Nina Manchego Elizabeth Martha
Published: April 2024

La actual crisis sanitaria ha destacado la falta de desarrollo de habilidades sociales en los profesores universitarios, en relación con su impacto en la educación académica y profesional de los estudiantes. En este contexto, algunos autores defienden la importancia de la empatía tanto cognitiva como emocional en el entorno educativo. Sin embargo, la actuación de los profesores no ha sido coherente con la adopción de esta perspectiva ni con la comprensión emocional. El propósito de este estudio es examinar el nivel de influencia de la empatía del profesor universitario en la formación académica de los estudiantes de maestría en educación durante la pandemia de Covid-19 en 2020, a través del análisis de los resultados del test de empatía cognitiva y afectiva. Se concluye que la empatía del profesor universitario es un elemento influyente en la formación académica y este trabajo contribuye a una comprensión limitada de los resultados de diversos instrumentos de desarrollo de habilidades sociales.

Published: April 2024

As we concentrate on addressing the challenges in responsible beauty product recommendation, particularly when it involves comparing the product’s color with a person’s skin tone, similar as for foundation and robe p conditions. The features uprooted using the prints from illuminated terrain can be largely deceiving or indeed be inharmonious to be compared with the product attributes. Hence bad illumination condition can oppressively degrade quality of the recommendation. We introduce a machine learning frame for illumination assessment which classifies images into having moreover good or bad illumination condition. We also make an automatic stoner guidance tool which informs a stoner holding their camera if their illumination condition is good or bad. This way, the stoner is handed with rapid-fire feedback and can interactively control how the print is taken for their recommendation. Only a many studies are devoted to this problem, substantially due to the lack of dataset that's large, labeled, and different both in terms of skin tones and light patterns. Lack of similar dataset leads to neglecting skin tone diversity. Thus, we begin by constructing a different synthetic dataset that simulates colorful skin tones and light patterns in addition to a being facial image dataset. Next, we train a Convolutional Neural Network (CNN) for illumination assessment that outperforms the being results using the synthetic dataset. Eventually, we dissect how the work improves the shade recommendation for colorful foundation products
Ultrasound-Assisted Extraction of Phenolic Compounds from Red Jute (Corchorus
olitorius L.) Leaves Using Aqueous Ethanol

Published: April 2024

Extraction of bioactive components from natural sources has recently gained
interest due to their medicinal benefits. Jute or “saluyot,” a fast-growing perennial
herb abundant in the Philippines, is known to have high nutritive value and is a good
source of phenolic compounds. This study focused on the optimization of the
ultrasound-assisted extraction of the antioxidant phenolic compounds from red jute
(Corchorus olitorius L.) using aqueous ethanol. Characterization of fresh jute leaf
samples showed that jute leaf contains 84.52 ± 0.00% w/w moisture, 3.81 ± 0.98% w/w
extractives, 11.67 ± 0.98% w/w total solids and total phenolic content (TPC) of 17.72 ±
0.36 mg gallic acid equivalent (GAE)/gram bone dried leaves (gdl). Screening of the five
factors (extraction temperature, extraction time, particle size, solid to solvent ratio
and ethanol concentration) showed that extraction temperature, extraction time and
ethanol concentration significantly affected the TPC of the extracts. Likewise, the
interaction of particle size and ethanol concentration (negative effect) is significant.
The optimum conditions were found to be 50 oC extraction temperature, 20 min extraction
time and 69.037% ethanol using suggested quadratic equations obtained through the models
generated via Central Composite Design. Optimum TPC was 15.08 ± 0.03 mgGAE/gdl and
optimum percent recovery was 85.11 ± 0.17%. Small percent differences (0.80% both) with
respect to predicted suggest high desirability of the model equations. The high recovery
of phenolic compounds with the aid of ultrasonication even at one extraction cycle is
therefore proven to be significant, suggesting the potential of jute as source of
phenolic compounds

Published: April 2024

Biochar’s potential value as a soil amendment is in continuous demand. However,
as-produced biochar comes in different forms and sizes making its application and
distribution challenging. Because there is a limited commercialized biochar pelletizer
machine in the Philippines, a biochar pelletizer was developed to meet the requirements
of the end-user and to produce a relatively efficient and comparatively inexpensive
machine. The developed pelletizer was fabricated in local shops. The pelleting mechanism
was composed of a horizontal die and two rollers. Pellet rollers were designed to press
the biochar against the die. As the mixture passed the holes, pellets were formed and
then fell to the catchment. The developed pelletizer was tested using three (3)
different feedstocks, namely: carbonized rice hull (CRH), carbonized coconut shell
(CCS), and carbonized wood chips (CWC). Cassava paste was utilized as the binder in
levels of 10%, 15%, and 20%, respectively. The pellets produced in the study were 13 mm
long with a range of 6.60 to 7.79% moisture content. Particle and bulk densities were
highest with CRH at 764.22 and 343.67 kg-m3, respectively. The hardness and durability
were highest with CWC with 1272.75 Pa and 87.48%, respectively. The highest actual
capacity was observed with the CRH at 678.22 kg/day. An analysis of variance showed that
the mean machine efficiency ranged from 67.86% to 71.02%, irrespective of the binder
level. On the other hand, the binder level had a significant effect on the pelleting
recovery with the highest recovery of 98.50%was achieved with a binder level of 20%. CCS
and CWC could hold water up to 101 to 104% of their weight and could resist up to 806.66
to 1559.6 Pa of pressure. The study recommends the testing of pellets with other
feedstock materials and other binder types and formulations.

Published: April 2024

En la vida y formación de los estudiantes en la academia, siempre existirán profesores que causen algún tipo de impacto en los estudiantes. Por supuesto que existe impacto de orden académico y emocional dependiendo de las circunstancias y momentos en donde se efectuaron acciones en diferentes escenarios de la vida institucional.  Sin embargo, el impacto además de ser positivo también puede ser negativo creando una serie de resultados que no favorecen el ámbito académico. Esos impactos generados a través del curso de una carrera como lo es efectivamente la de Cirujano Dental, dejan huellas imperecederas en la mente de nuestros estudiantes evocando buenos y malos recuerdos que permanecen durante su existencia. El conocimiento impartido y la comunicación efectiva con los estudiantes resulta en un impacto integral que perdura en la vida del estudiante y posteriormente profesional.

Authors: Dharma Samjotha , Purushotham Sahana , Surendran Sreeraj
Published: April 2024

Introduction and Aim: While numerous studies have explored the connection between ABO blood groups and disease incidence in various medical contexts, there has been a scarcity of research dedicated to examining the relationship between ABO blood groups and the occurrence of oral diseases with a specific focus on those with and without Type II diabetes mellitus. Understanding the patient’s blood group and salivary secretor status might help to create a new qualitative personalized approach in preclinical diagnosis and to develop preventive measures. Hence, this study delves into the correlation between ABO phenotypes, Rhesus factor, and salivary secretor status in chronic periodontitis patients, with and without Type 2 Diabetes Mellitus
 
Materials and Methods: The study sample comprised 120 subjects aged between 35 and 60 years. Participants were categorized into three groups: Group A, consisting of patients with only chronic periodontitis; Group B, including patients with only Type II Diabetes Mellitus; and Group C, comprising individuals with both chronic periodontitis and Type II Diabetes Mellitus. Salivary secretor status was determined using the absorption elution method.
 
Results: Group B showed the highest percentage of salivary secretors (97.5%), followed by group A (95%) and group C showed the least percentage of secretors (92.5%). Group B showed the least percentage of non-secretors (2.5%), Group A showed 5% and group C showed the highest percentage of non-secretors (7.5%). The common blood groups in Study Group A were O>B>A>AB. Similarly in Group B, the blood groups were B>O=A>AB and finally in Study Group C, the common blood groups were B>A>O>AB. Majority of the individuals were Rh Positive.
 
Conclusion: The current study has identified a correlation between ABO phenotype, Rh phenotype, and secretor status among individuals with periodontitis, both with and without type 2 diabetes.

Authors: M.N. Nidhita , Bhaktha Geetha , S. Prashanth
Published: April 2024

Introduction and Aim: Pregnancy demands vigilant fetal monitoring, yet traditional methods have limitations, leading to research on biomarkers like placental growth factor (PLGF) to enhance predictive accuracy for adverse outcomes. This investigation focuses on assessing the relationship between PLGF levels and pregnancy outcomes in women with suspected preeclampsia.
 
Materials and Methods: A simple longitudinal design was employed, following pregnant women with suspected preeclampsia from enrollment until delivery. The study included 160 subjects, and their characteristics were recorded at admission. PLGF levels were measured, and pregnancy outcomes were assessed.
 
Results: Among the study population, the distribution of pregnancies showed that 45.62% were in the first pregnancy, 40% in the second pregnancy, 11.85% in the third pregnancy, and 2.5% in the fifth pregnancy. The highest PLGF levels were observed in the fifth pregnancy group.Analysis revealed that subjects with NICU admission had a lower mean PLGF value compared to those without NICU admission. Among subjects with low PLGF levels, the mean baby weight was lower by approximately 5.3% when match up to those with normal PLGF levels.Regarding blood pressure, subjects with decreased PLGF levels had a higher mean systolic blood pressure in contrast   to those with normal PLGF levels.
 
Conclusion: Lower PLGF levels were associated with NICU admission, lower baby weight, and higher systolic blood pressure in women with suspected preeclampsia. These findings suggest that PLGF levels may have implications for pregnancy outcomes. Additional investigation with expanded sample sizes is necessary to authenticate these discoveries and look into the clinical relevance of PLGF in understanding and addressing preeclampsia.

The burden of diseases can be greatly reduced by reducing air pollution which is one of the greatest risks to health in our environments. The study assessed the different types of micro-organisms present in a major and minor abattoir in Akure metropolis of Ondo state, Nigeria and their sensitivity to Antibiotics. Pre-tested questionnaires were used to obtain socio-demographic information, how the environment of the abattoir is sanitized and diseases likely to be contacted from the workers working in the abattoirs. Different levels of occurrence of isolates were observed in the major and minor abattoirs and the total count was done with the total bacteria counts ranging from lowest to highest. The total count for Escherichia coli range from 3.6×10 cfu/ml to 6.5 ×10 cfu/ml, while the total bacteria count ranged from 1.34×10 cfu/ml to 2.55×10 cfu/ml, also total coliform ranged from 2.8×10 cfu/ml to 4.1×10 cfu/ml at the major abattoir. The total count for Escherichia coli range from 5.7×10 cfu/ml to 7.2×10 cfu/ml, while the total bacteria count range from 5.2×10 cfu/ml to 1.56×10 cfu/ml, also total coliform ranged from 3.4×10 cfu/ml to 4.3×10 cfu/ml at the minor abattoir. During gram staining test it was observed that three out of the eight organisms namely, Micrococcus luteus, bacillus spp, Staphylococcus aureus, were gram positive, while Escherichia coli, Proteus mirabilis, Proteus vulgaris, Enterobacter aerogenes and Aeromonas sppwere gram negative. Antibiotic sensitivity was carried out on each of the isolates. Ciprofloxacin antibiotic had inhibitory effect on both grampositive bacteria with the highest effect on Staphylococcus aureus at 24mm and gram negative bacteria with highest result on Escherichia coli at 21mm. Therefore, there is presence of pathogenic micro-organisms especially Escherichia coli in the air environment of the abattoirs. Conclusively, there is need for routine environment sanitation of these slaughter houses because inhalation of air from these abattoirs can constitute a great environmental menace to the workers and residents around the area where they are situated, resulting in health complications to those with existing health challenges.

Multi-decadal atmospheric carbon dioxide measurements in Central Europe, Hungary
Authors: Haszpra László
Published: April 2024

Abstract. The paper reviews and evaluates a 30-year-long atmospheric CO2 data series measured at Hegyhátsál tall-tower greenhouse gas monitoring site, a member of WMO GAW, NOAA, and ICOS networks (id. code: HUN). The paper also gives the technical description of the monitoring system, and that of the physical environment of the station. This low elevation (248 m above m.s.l.), mid-continental Central European site shows a 3.90±0.83 µmol mol‑1 offset relative to the latitudinally representative marine boundary layer reference concentration presumably due to the European net anthropogenic emissions. The long-term trend (2.20 µmol mol‑1 year‑1) closely follows the global tendencies. In the concentration growth rate, the ENSO effect is clearly detectable with a 6–7 months lag-time. The summer diurnal concentration amplitude is slightly decreasing due to the faster-than-average increase of the nighttime concentrations, which is related to the warming climate. The warming climate also caused a 0.96±0.41 day year‑1 advance in the beginning of the summer CO2-deficit season in the first half of the measurement period, which did not continue later.
Rates of palaeoecological change can inform ecosystem restoration

Published: April 2024

Abstract. Accelerations of ecosystem transformation raise concerns, to the extent that high rates of ecological change may be regarded amongst the most important ongoing imbalances in the Earth system. Here, we used high-resolution pollen and diatom assemblages and associated ecological indicators (the sum of tree and shrub pollen and diatom-inferred total phosphorus concentrations as proxies for tree cover and lake-water eutrophication, respectively) spanning the past 150 years to emphasize that rate-of-change records based on compositional data may document transformations having substantially different causes and outcomes. To characterize rates of change also in terms of other key ecosystem features, we quantified for both ecological indicators: (i) the percentage of change per unit time, (ii) the percentage of change relative to a reference level, and (iii) the rate of percentage change per unit time relative to a reference period, taking into account the irregular spacing of palaeoecological data. These measures document how quickly specific facets of nature changed, their trajectory, as well as their status in terms of palaeoecological indicators. Ultimately, some past accelerations of community transformation may document the potential of ecosystems to rapidly recover important ecological attributes and functions. In this context, insights from palaeoecological records may be useful to accelerate ecosystem restoration.

Abstract. The Geostationary Environment Monitoring Spectrometer (GEMS) launched in February 2020 is now providing continuous daytime hourly observations of nitrogen dioxide (NO2) columns over East Asia (5° S–45° N, 75° E–145° E) with 3.5 × 7.7 km2 pixel resolution. These data provide unique information to improve understanding of the sources, chemistry, and transport of nitrogen oxides (NOx) with implications for atmospheric chemistry and air quality, but opportunities for direct validation are very limited. Here we correct the operational level-2 (L2) NO2 vertical column densities (VCDs) from GEMS with a machine learning (ML) model to match the much sparser but more mature observations from the low Earth orbit TROPOspheric Monitoring Instrument (TROPOMI), preserving the data density of GEMS but making them consistent with TROPOMI. We first reprocess the GEMS and TROPOMI operational L2 products to use common prior vertical NO2 profiles (shape factors) from the GEOS-Chem chemical transport model. This removes a major inconsistency between the two satellite products and greatly improves their agreement with ground-based Pandora NO2 VCD data in source regions. We then apply the ML model to correct the remaining differences, Δ(GEMS-TROPOMI), using as predictor variables the GEMS NO2 VCDs and retrieval parameters. We train the ML model with collocated GEMS and TROPOMI NO2 VCDs, taking advantage of TROPOMI off-track viewing to cover a wide range of effective zenith angles (EZAs) for the GEMS diurnal profiles. The two most important predictor variables for Δ(GEMS-TROPOMI) are GEMS NO2 VCD and EZA. The corrected GEMS product is unbiased relative to TROPOMI and shows a diurnal variation over source regions more consistent with Pandora than the operational product.

Abstract. The aerosol particles that provide cloud condensation and ice nuclei contribute to key cloud processes associated with cold-air outbreak (CAO) events but are poorly constrained in climate models due to sparse observations. Here we retrieve aerosol size distribution modes from measurements at Andenes, Norway during the Cold-Air Outbreaks in the Marine Boundary Layer Experiment (COMBLE) and at Zeppelin Observatory, approximately 1000 km upwind in Svalbard. During CAO events at Andenes, the sea spray mode number concentration is correlated to strong over-ocean winds with a mean of 8±4 cm-3 that is 71 % higher than during non-CAO conditions. Additionally during CAO events at Andenes, the mean Hoppel minimum diameter is 6 nm smaller than during non-CAO conditions though the estimated supersaturation is lower and the number concentration of particles that likely activated in-cloud is 109±61 cm-3 (similar to non-CAO conditions). For CAO trajectories between Zeppelin Observatory and Andenes, the upwind-to-downwind change in number concentration is largest for the accumulation mode with a mean decrease of 93±95 cm-3, likely attributable primarily to precipitation scavenging. These characteristic properties of aerosol size distributions during CAO events provide guidance for evaluating CAO aerosol-cloud interaction processes in models.

Abstract. This study advances the understanding of climate projection uncertainties in the Nemunas River, Curonian Lagoon, and southeastern Baltic Sea continuum by analyzing a subset of climate models, focusing on a coupled ocean and drainage basin model. Four downscaled and bias-corrected high-resolution regional atmospheric climate models were used to set up the hydrological (SWAT) and hydrodynamic (SHYFEM) modeling system. This study investigates the variability and trends in environmental parameters such as water fluxes, timing, nutrient load, water temperature, ice cover, and saltwater intrusions under Representative Concentration Pathway 4.5 and 8.5 scenarios. The analysis highlights the variability among model results underscoring the inherent uncertainties in forecasting climatic impacts, hence highlighting the necessity of using multi-model ensembles to improve the accuracy of climate change impact assessments. Additionally, modeling results were used to evaluate the possible environmental impact due to climate change through the analysis of the cold water fish species reproduction season. We analyze the duration of cold periods (<1.5 °C) as a thermal window for burbot spawning, calculated assuming different climate forcing scenarios and models. The analysis indicated coherent shrinking of the cold period and presence of the changepoints during historical and different periods in the future, however, not all trends reach statistical significance, and due to high variability within the projections, they are less reliable. This means there is a considerable amount of uncertainty in these projections, highlighting the difficulty in making reliable climate change impact assessments.
