Cell division was identified as one of the least learned competencies in teaching biological science to junior high school students. Comics’ combination of pictures and words makes the process more engaging to students by changing their perspective on learning. Reading literacy and motivation are improved by contextualized comic books. The use of comic books as instructional material significantly influences academic attainment, particularly for low achieving youngsters. As a result, instructors’ teaching strategies and approaches reflect the growth and inclusion of comics in teaching-learning. The study aimed to develop and assess a contextualized comic book teach-ing cell division concepts to improve students’ conceptions. The research used a modified exam from the General Biology book based on Curriculum Guide Competency and Most Important Learning Competency (MELC). The accomplishment exam consisted of 20 items covering the following topics: Cell Division/ Cell Cycle. The contextualized comic book was rated accept-able and with moderate agreement by the evaluators. The findings showed that the developed contextualized comic book positively influenced the knowledge level of the student’s cell division concepts. Moreover, there was a significant difference between the student’s pre-test and post-test mean scores. Additionally, they positively perceived that the developed contextualized comic book had increased their interest and creativity and enhanced their knowledge and understanding of Cell Division. Because of their significance to the teaching process, instructional comics are suggested for inclusion in many courses, notably in science.

This research aims to examine teacher’s initial perceptions of STEM Education. The participants in this study were 43 in-service STEM related subject teachers from the northeastern region in Thailand who were keen on participating in the STEM Education for Educators Module, Khon Kaen University. The data was collected through an open-ended questionnaire of Teacher’s Perceptions of STEM Education (TP-STEM) prior to the process of professional development beginning. The aspects of TP-STEM included (1) STEM concept; (2) Experience implementing STEM; (3) STEM PK; (4) Teacher’ competency for STEM education; (5) Assessment in STEM education; (6) Supporting STEM education in schools; and (7) Research in STEM education. An interpretative paradigm was implemented as a methodology to interpret qualitative data in this research. Research findings were discussed around seven aspects of teacher’s perceptions of STEM education according to the TPSTEM questionnaire. The findings reveal that teacher’s perceptions of the STEM concept goes around the term integrated STEM disciplines. Surprisingly, the majority of teachers had never implemented STEM education in their teaching and a number of teachers tend to separate STEM teaching into each discipline rather than link the disciplines for problem solving. Key PK in STEM education was emphasised on practicing, active learning, and integrated disciplines. Teacher’s indicated PK (PK) as the most significant competency for STEM education, whereas partnership was also considered as a competency to support successful STEM implementation. Authentic assessment and formative assessment were emphasised as key features for assessment in STEM education. Teachers indicated good organisation and support from schools on resources, policy, and professional development for successful STEM implementation. Also, enhancing student’s skills, and innovation were indicated as a focus for STEM education research. These findings could explicitly indicate the trail for professional development (PD) provided that teacher’s ideas about STEM education are related closely to the STEM philosophy from the basic background to implications for a more efficient outcome for implementing STEM education in schools. Moreover, there were indications of the need for support from the Ministry of Education, school administrations, and experts from universities in order to produce effective STEM Education in Thailand. The paper has implications for STEM education professional development not only in Thailand but also for Asia Pacific countries.

Measuring students’ conceptual understanding is a challenge for teachers. Teachers usually use open-ended instruments to measure students’ conceptual understanding in depth. However, this instrument is considered highly subjective in the assessment and requires a relatively long time to check the answers. Computerised Testlet instruments developed by combining the advantages of open-ended and closed-ended instruments are deemed the solution to these problems. This study, therefore, aims to analyse the quality of the Computerised Testlet instrument psychometrically. The Rasch analysis model with Winsteps software was used in this study. A total of 10 Testlet items with three supporting questions were developed on the topic of stoichiometry. A total of 413 students (N = 413: 236 female, 177 male) from three different schools took tests on stoichiometry using the Testlet instrument, which was provided through a web developed previously (computerised). Rasch analysis model helped psychometric analysis regarding reliability, linear validity of students’ knowledge, and difficulty of items. This study reveals that Computerised Testlet able to identify students’ thinking processes. Besides, the psychometric analysis results showed that using Testlet to measure conceptual knowledge had good unidimensionality and reliability; it could be used to measure stoichiometric conceptual knowledge. Some questions needed to be revised as they proved unable to distinguish between high and low students’ conceptual knowledge; in general, the instrument could be used and provided a good function in analysing conceptual knowledge on the topic of stoichiometry.

Authors: Paymulina Anastasia , Potoroko Irina , Naumenko Natalia , Motovilov Oleg
Published: March 2023

Algae are a source of many biologically active compounds that can be used in food production to expand the range of functional products. For instance, sodium alginate possesses a complex of scientifically proven biologically active properties. In the food industry, it usually serves as a thickener, stabilizer, gelatio n agent, and water-retaining agent. The biological activity of this polysaccharide and its effect on the technological properties of food systems depend on the molecular weight and particle size uniformity. The present research objective was to study the method of sonochemical microstructuring of sodium alginate to increase its biological activity and efficiency as part of v arious bakery formulations.

The research featured alginate gels, yeast suspensions of Saccharomyces cerevisiae, and bakery products. The sonochemical microstructuring of sodium alginate involved a low-frequency ultrasonic treatment at 240, 435, and 630 W/L and 50°C for 20, 25, and 30 min. The effect of the treatment included the following indicators: particle morphology vs. distribution of the hydrodynamic particle diameter in a dispersed medium, antioxidant activity, dynamic viscosity, in vitro bioactivity, and bioavailability against Paramecium caudatum and S. cerevisiae. The quality assessment of bakery products followed State Standard 58233-2018.

The process of sonochemical microstructuring depolymerized large particles of sodium alginate into shorter ones: 5670 nm – 30.6%, 502 nm – 53.4%, 56.1 nm – 16%. It increased the antioxidant activity by 7 times and the potential in vitro bioactivity by 3.9%. The microstructured sodium alginate improved the fermentation activity of S. cerevisiae and reduced the yeast biomass by 8%. The resulting bakery products had a greater porosity by 5.9% and antioxidant activity by 3.7 times.

The sonochemical microstructuring reduced the particle size of sodium alginate, as well as increased its biological activity. The sonochemically microstructured sodium alginate demonstrated a great potential for baked foods.

Published: March 2023

Benefit of dietary fiber has proven by clinical studies. Dietary fiber can be incorporated into food products with whole grain cereals. Whole barley tolokno is a valuable source of soluble dietary fiber β-glucans. As a result, it is often used in fortified bakery products. The research objective was to modify the dietary profile of biscuits by substituting refined wheat flour with barley tolokno.

The study featured refined wheat flour, barley tolokno, composite flours, model suspensions, and formulations of biscuits. Standard methods helped to measure the sensory profile, physicochemical parameters, fatty acid composition, structural characteristics, and mechanical properties of the research objects.

The content of dietary fiber in the flour and the tolokno was 3.7 and 19.8%, respectively. The fatty acid composition of the tolokno differed from that of the wheat flour. The content of oleic acid was 21.1 in the tolokno and 15.9% in the flour, while the content of linoleic acid was 46.8 in the tolokno and 54.0% in the flour. A greater proportion of tolokno in the composite flour led to an increase in the content of dietary fiber (3.7–11.8%), protein (11.5–12.8%), and fat (1.4–2.7%). The water and fat absorption capacity of composite flours increased by 125 and 65.7%, respectively, when the share of tolokno reached 50%. As the proportion of tolokno increased, the viscosity of the model suspensions rose from 3.1 to 17.3 Pa·s at a minimal shear rate. The water absorption capacity of the control sample was 190%: in the experimental biscuits, it rose from to 221 and 227% at 30 and 40% of tolokno, respectively. Extra tolokno also increased the content of dietary fiber in the biscuit, which reached 7.53% in the sample with 50% tolokno. The experimental biscuits were even in shape, surface, and porosity; they had a balanced taste and a pleasant smell with a slight grainy tint.

The optimal proportion of barley tolokno was 40%. This amount brought up the content of dietary fiber to 6.5 g per 100 g. The resulting biscuits could be classified as products rich in dietary fiber (Technical Regulations of the Customs Union 022/2011). The research made it possible to expand the range of functional biscuits fortified with native dietary fiber and whole grain raw materials.
Effect of Microwave Radiation on the Chemical Composition of Chickpeas
Authors: Khramova Valentina , Surkov Dmitry , Lubchinsky Kirill
Published: March 2023

Chickpea (Cicer arietinum L.) is rich in protein and has a balanced amino acid profile. However, its characteristic bean flavor limits its use as a functional food ingredient. Microwave treatment may help to solve this problem. The research objective was to select the optimal parameters of microwave treatment to obtain chickpea samples with no bean flavor and to study their chemical composition.

The study featured chickpeas of the Volzhanin variety. The experimental samples were processed in a microwave oven with a magnetron frequency of 2450 MHz at different power and time values. The protein tests, the analysis of amino acid profile, and the sensory assessment involved standard research methods.

The microwave processing loosened the consistency of chickpeas and eliminated the bean flavor after 5–6 min at 200 W or 3 min at 400 W. A longer treatment time resulted in a peanut flavor followed by bitterness. The microwave treatment reduced the mass fraction of protein and the amount of essential amino acids. This process could be slowed down by increasing the power of microwave radiation and reducing the processing time. However, the intensification had a negative effect on the content of arginine, methionine, and tyrosine in chickpea protein.

The results obtained can make it possible to use chickpeas as a functional food ingredient.

Authors: Chaplygina Olga , Kozlova Oksana , Zharko Maria , Petrov Andrey
Published: March 2023

Antibiotics have traditionally been used to prevent and treat common diseases in farm animals. However, residual antibiotics in dairy products and meat remain a serious public health problem, which is associated with antibiotic resistance. The research objective was to assess the impact of antibiotic contamination on the quality and safety of dairy products, the microbiological composition of milk, and antibiotic-resistant bacteria.

The study featured six years of Russian and foreign scientific articles registered in PubMed (National Center for Biotechnology Information, USA), Scopus and ScienceDirect (Elsevier, the Netherlands), Web of Science (Clarivate, USA), and eLibrary.ru.

The analysis involved 63 foreign and domestic sources. Residual antibiotics in milk inhibits the vital activity of lactic acid bacteria, which, in its turn, disrupts the technological process of yogurts, cheeses, etc. After such processing as normalization, pasteurization, and homogenization, antibiotics accumulate in fermented dairy products and bind with milk proteins and fats. Antibiotics, in their initial amount, enter yoghurts from dairy raw materials. In cheese production, antibiotics usually pass into the whey, but aminoglycosides, quinolones, and tetracyclines remain in the finished product because they bind with the protein fraction.

The problem of biological safety of dairy products is associated with antibiotic resistance developed by human intestinal microbiota. This problem remains understudied, and the number of scientific papers on the matter is limited.

Electric mobility is one of the key technologies for the replacement of non renewable energy sources in the long term; creating new markets, opportunities, and
new technologies, as the old energy order comes to an end with the evolution of new
ones. With the passing of around two centuries, electric vehicle technology has
developed to different levels across the globe. Norway has the highest percentage of
electric vehicles, while China has the highest number of electric vehicles sold per year
in the world. India is catching up with electric vehicle penetration. As per 2018 data,
49% of the total vehicles sold in Norway were electric. In 2019, China registered the
maximum number of electric vehicles sold – 1.15 million vehicles. The key advantages
of e-mobility are a reduction in GHG emissions, a reduction in the dependency on
fossil fuels, higher efficiency compared to ICE vehicles, fewer noise emissions, and the
flexibility of EVs becoming a platform for collaborative development of autonomous
cars and shared mobility and MaaS. The key challenges are the total cost of ownership,
charging infrastructure, reliance on the imported content and parts, customer
acceptance of EVs, vehicle range anxiety and battery manufacturing, and availability of
raw materials. This research investigates in detail the opportunities created by
technologies such as solar-powered vehicle charging, the second life of traction battery,
smart grid integration, connected and autonomous CAVE and vehicle light-weighting
to enable e-mobility as a more commercial means of transportation

Published: March 2023

The current scenario in the field of aviation is focused on hypersonic-speed
vehicles. To achieve the required performance, engines have to be designed in such a
way that their outcome should be maximum. Nowadays high-speed performance
engines have utilized a type of air-breathing engine amongst which, the scramjet is
found appropriate. However, the engine can only perform under atmospheric area
because the supersonic combustion ramjet engine utilizes the atmospheric air as an
oxidizer. Nonetheless, engines do not comprise any rotating or moving parts. So, to
complete the mixing and chemical kinetics, engine geometry has special dimensions.
The present chapter is focused on a rigorous review of the geometrical modification of
the combustor and fuel injector. The impact of mixed fuel, different types of working
fuels, and variable inflow conditions have been explored to uncover the beneficial
effects on scramjet combustion performance. Since numerous authors have explored
different aspects of the ongoing challenges in scramjet hence a summary has been
drawn to acquire a suitable model for future work.

Pros and Cons of Artificial Intelligence in Education: A Review
Authors: Ghosal Barnali
Published: March 2023

The COVID-19 pandemic has truly become a watershed in the global
education scenario, resulting in an unprecedented surge in the advancement of
educational technology. The usage of Artificial Intelligence (AI), whose reach is
expanding in the post-pandemic era is one such quickly rising trend in the education
industry. To put it simply, it is the field of study dealing with machines that have
human-like intelligence and other traits like adaptability, problem-solving, and
learning. The use of artificial intelligence is working as a relief for teachers from their
tedious administrative work such as grading student assignments, and on the other
hand, it provides personalized and customized learning experiences to the learners
based on their own needs and interests, which in turn, facilitates effective learning.
However, the application of artificial intelligence in education is not a bed of roses.
Apart from the risks of lessening human contact and being a threat to the human
workforce, there is another crucial issue - as pointed out by UNESCO - of inclusion
and equity, especially in developing countries where neither every school nor every the
learner has the means necessary to benefit from the advent of artificial intelligence.
This chapter makes an effort to delve into the pros and cons of applying artificial
intelligence in education through a qualitative research approach by doing a review of
existing literature.

Enabling Early Health Care Intervention by Detecting Depression in Users of Web-Based Forums using Language Models: Longitudinal Analysis and Evaluation
Authors: Owen David , Antypas Dimosthenis , Hassoulas Athanasios , Pardiñas Antonio F , Espinosa-Anke Luis , Collados Jose Camacho
Published: March 2023

Background

Major depressive disorder is a common mental disorder affecting 5% of adults worldwide. Early contact with health care services is critical for achieving accurate diagnosis and improving patient outcomes. Key symptoms of major depressive disorder (depression hereafter) such as cognitive distortions are observed in verbal communication, which can also manifest in the structure of written language. Thus, the automatic analysis of text outputs may provide opportunities for early intervention in settings where written communication is rich and regular, such as social media and web-based forums.

Objective

The objective of this study was 2-fold. We sought to gauge the effectiveness of different machine learning approaches to identify users of the mass web-based forum Reddit, who eventually disclose a diagnosis of depression. We then aimed to determine whether the time between a forum post and a depression diagnosis date was a relevant factor in performing this detection.

Methods

A total of 2 Reddit data sets containing posts belonging to users with and without a history of depression diagnosis were obtained. The intersection of these data sets provided users with an estimated date of depression diagnosis. This derived data set was used as an input for several machine learning classifiers, including transformer-based language models (LMs).

Results

Bidirectional Encoder Representations from Transformers (BERT) and MentalBERT transformer-based LMs proved the most effective in distinguishing forum users with a known depression diagnosis from those without. They each obtained a mean F1-score of 0.64 across the experimental setups used for binary classification. The results also suggested that the final 12 to 16 weeks (about 3-4 months) of posts before a depressed user’s estimated diagnosis date are the most indicative of their illness, with data before that period not helping the models detect more accurately. Furthermore, in the 4- to 8-week period before the user’s estimated diagnosis date, their posts exhibited more negative sentiment than any other 4-week period in their post history.

Conclusions

Transformer-based LMs may be used on data from web-based social media forums to identify users at risk for psychiatric conditions such as depression. Language features picked up by these classifiers might predate depression onset by weeks to months, enabling proactive mental health care interventions to support those at risk for this condition.

Authors: Van Mens Kasper , Lokkerbol Joran , Wijnen Ben , Janssen Richard , de Lange Robert , Tiemens Bea
Published: March 2023

Background

Predicting which treatment will work for which patient in mental health care remains a challenge.

Objective

The aim of this multisite study was 2-fold: (1) to predict patients’ response to treatment in Dutch basic mental health care using commonly available data from routine care and (2) to compare the performance of these machine learning models across three different mental health care organizations in the Netherlands by using clinically interpretable models.

Methods

Using anonymized data sets from three different mental health care organizations in the Netherlands (n=6452), we applied a least absolute shrinkage and selection operator regression 3 times to predict the treatment outcome. The algorithms were internally validated with cross-validation within each site and externally validated on the data from the other sites.

Results

The performance of the algorithms, measured by the area under the curve of the internal validations as well as the corresponding external validations, ranged from 0.77 to 0.80.

Conclusions

Machine learning models provide a robust and generalizable approach in automated risk signaling technology to identify cases at risk of poor treatment outcomes. The results of this study hold substantial implications for clinical practice by demonstrating that the performance of a model derived from one site is similar when applied to another site (ie, good external validation).
A Web-Based Gender-Sensitive Educational Simulation on Vocational Rehabilitation for Service Providers Working With Youth With Disabilities: Pilot Evaluation (Preprint)
Authors: Lindsay Sally , Thomson Nicole , Moll Sandra , Colantonio Angela , Stinson Jennifer
Published: March 2023

BACKGROUND

Although there is a need for gender-specific health care, especially within the context of vocational rehabilitation for youth with disabilities, clinicians, trainees, and community service providers commonly report lacking training in gender-sensitive approaches. Therefore, an educational tool designed for clinicians working with youth, that addresses how to approach such issues, could help clinicians to augment the care they provide.

OBJECTIVE

The objective of our study was to conduct a pilot evaluation of an educational simulation for health care and service providers focusing on gender-sensitive approaches within the context of supporting youth with disabilities in vocational rehabilitation.

METHODS

We conducted a survey from May to September 2021 to assess the relevance of the simulation content, preliminary perceived impact on gender-sensitive knowledge and confidence, and open-ended feedback of a web-based gender-sensitive educational simulation. A total of 12 health care providers from a variety of professions who had experience working with youth in the context of vocational rehabilitation participated in the survey (11 women and 1 man).

RESULTS

Most participants reported that the content of the simulation was relevant and comprehensive. The majority of participants reported that the simulation helped to increase their perceived knowledge or understanding of the topic, changed their perceived understanding of their intervention or approach, and informed their perceived confidence. Our qualitative findings from the open-ended questions highlighted three main themes: (1) relevance of the simulation content, (2) perceived impact for clinical practice (ie, gender-sensitive language and communication and building rapport with patients), and (3) perceived impact on organizational processes (ie, practices, policy, and privacy).

CONCLUSIONS

Our educational simulation shows preliminary potential as an educational tool for service providers working with youth who have a disability within the context of vocational rehabilitation. Further research is needed to assess the impact of the tool with larger samples.

Published: March 2023

The core of building first-class applied curriculum is to cultivate first-class applied talents, and the key lies in first-class applied curriculum design. This paper adheres to the concept of results-oriented education (OBE), centering on tasks, main lines, and processes, to meet the needs of application-oriented undergraduate first-class curriculum design and practice. This paper proposes, practices and improves the six-step teaching method based on constructivism, which includes “raising questions (creating situations), discussing problems, introducing hot topics, constructing new knowledge, applying concepts, evaluating effects and reflecting”. It reasonably integrates the case elements of “curriculum ideology and politics”, making the two main courses of “knowledge imparts” and “value guidance” reach the curriculum objectives.
Litoesculturas del período Formativo en Chillia (Patáz, La Libertad-Perú): una aproximación a su cronología y significado.
Authors: Villar Quintana Anthony
Published: March 2023

El artículo presenta el estudio de las representaciones de dos litoesculturas provenientes de Chillia y Ushno de Agotuna, dos sitios arqueológicos del distrito de Chillia, en la provincia de Pataz, departamento de La Libertad, en el norte peruano. Dicha investigación consistió en un estudio inicial y general de las representaciones iconográficas plasmadas en estos soportes líticos.
Mediante esta investigación se busca reconocer el estilo y posición cronológica de ambas esculturas dentro del período Formativo. De esta manera, también buscamos aproximarnos a las implicancias de estas representaciones en la cosmovisión de quienes las elaboraron. Consideramos así, que la litoescultura de Chillia fue elaborada entre el Formativo Temprano y Medio, mientras que la de Ushno de Agotuna entre el Formativo Medio y Tardío. Las representaciones plasmadas en ambas litoesculturas presentan rasgos que podrían definirlos como seres míticos, deidades u oficiantes de cultos religiosos. Por otra parte, también notamos que algunos aspectos de estas representaciones reflejan que esta área estuvo inserta dentro de flujos de interacción interregionales.

Abstract: Wind turbines are the most ancient known means of extracting energy from natural sources (wind in this case). It is not possible to create high consistent power from a wind turbine due to changeable weather and wind speed, but a small-scale wind turbine can be used to power tiny appliances at home and in moving vehicles. This research investigates the design features of an innovative small-scale wind turbine intended to supply power. The paper covers design, improvement, power management, and production procedures.

Published: March 2023

Abstract: Deep learning, integrated with Artificial Intelligence algorithms, has brought about numerous beneficial practical technologies. However, it also brings up a problem that the world is facing today. Despite its innumerable suitable applications, it poses a danger to public personal privacy, democracy, and corporate credibility. One such use that has emerged is deepfake, which has caused chaos on the internet. Deepfake manipulates an individual's image and video, creating problems in differentiating the original from the fake. This requires a solution in today's period to counter and automatically detect such media. This study aims to explore the techniques for deepfake creation and detection, using various methods for algorithm analysis and image analysis to find the root of deepfake creation. This study examines image, audio, and ML algorithms to extract a possible sign to analyze deepfake. The research compares the performance of these methods in detecting deepfakes generated using different techniques and datasets. As deepfake is a rapidly evolving technology, we need avant-garde techniques to counter and detect its presence accurately.

We have used FTIR for study of coals from different deposits of Mongolia. As a measurements result, IR spectra of all coals have organic and inorganic bands. Khushuut coal spectrum owns more C-C bands than other coals, which can be related to its high carbonization. Coals from Uvurchuluut, Aduunchuluu, Baganuur and Nalaikh have hydroxyl group bands more than others which may relate their high content of moisture.
