PRE-SERVICE CLASSROOM TEACHERS’ MISLEARNINGS OF CLASSIFICATION OF THE PLANT KINGDOM AND THE EFFECT OF PORPHYRIOS TREE ON REMOVING THEM
Authors: Yangin Selami
Published: February 2022

Students may acquire mislearnings in the course of their academic lives for various reasons and keep them for a lifetime. Some of the most common of those mislearnings are the alternative conceptions university students have about Biology lesson. This study was conducted through one-to-one interviews with 54 students at the 1st grade of the Department of Classroom Teaching in order to determine university students’ alternative learnings about the classification and the diversity of plants and remove these alternative learnings if there were any. In the end, it was found that students had mislearnings about the classification and the diversity of plants. The main mislearning was that students classify some of the plants they knew well in a wrong way according to the criteria which was not biological; for example, they thought fern and bryophyte were plants with seeds, fungi were plants, and the plants belonging to the family of Pinaceae did not have real leaves so they were included in the class of plants without seeds. In order to remove these mislearnings ‘Porphyrios Tree’, which has a structure similar to a concept map, was used. As a result, a great majority of pre-service teachers’ alternative conceptions about the classification of plants were removed through this method of application. Key words: classification, mislearnings, plants, porphyrios tree, pre-service teachers.

Authors: Záhorec Ján , Hašková Alena , Munk Michal , Bílek Martin
Published: February 2022

In the PISA scientific literacy monitoring carried out in 2006 and 2009 Slovak students achieved results below the OECD average scores while Czech students achieved significantly better results. Following the PISA results there was carried out a research aimed at evaluation of the current state of computer science education/informatics teaching at an upper secondary school level in both countries and moreover also in Belgium. In all three concerned countries a lack of textbooks of an appropriate quality was identified as a main weakness. Further identified weaknesses were: in Slovakia a problem of a lack of tasks attractive for students, in the Czech Republic a weak attractiveness of the teacher's presentation of new material for students and identically to Belgium a lack of engagement of students in tasks solved in class. Positively evaluated was: in Slovakia attractiveness of the curriculum and methods of new material presentation by teachers, and in the Czech Republic and Belgium clarity of the teacher’s presentation of new curriculum.
Key words: monitoring of students` scientific literacy, current state of computer science education, evaluation of informatics teaching, strengths and weaknesses of informatics teaching, international comparison.
THE IMPACT OF SITE-VISITS ON THE DEVELOPMENT OF BIOLOGICAL COGNITIVE KNOWLEDGE
Authors: Muscat Miriam , Pace Paul
Published: February 2022

Classroom-based science teaching tends to be dominated by teaching that stifles the students’ natural curiosity and eagerness to discover their surroundings. Knowledge makes sense to students particularly when it is learned within the context of an authentic experience. Thus classroom-based science needs to be complimented by out-of-classroom activities which offer direct and relevant information that influences students’ learning. Students build new knowledge on already existing schema, thus it is important for both teacher and students to question and evaluate their knowledge to be able to build on solid grounds. This paper illustrates examples of meta-cognitive tools (i.e. Vee diagrams and concept maps) used before and after site-visits to explore the contribution of out-of-classroom activities to the students’ biological cognitive development. This research shows that site-visits are a necessary part of science learning because they help students develop observational and reasoning skills, link biology to personal life experiences and contextualise inert classroom knowledge, making it more meaningful and easier to remember.
Key words: concept maps, meta-cognitive tools, out-of-classroom activities, site-visits, Vee diagrams.

NATURAL SCIENCE EDUCATION IMPORTANCE IN ADOLESCENCE
Authors: Lamanauskas Vincentas
Published: February 2022

Natural science importance is indubitable. Research studies of the last few decades confirm such position. Science education has been frequently accepted as an inseparable and extremely important part of comprehensive schooling (Lamanauskas, 2008). By natural education we seek personality maturity in a wider sense. It would seem that everything is said concerning this question. However, it is not so. Rapid spread of scientific cognition inevitably raises new challenges for natural education, induces to re-evaluate generally used education strategies and methodologies. There is a rapid development of ICT; their penetration into educational environments is really intensive, though not always adequate to the raising educational goals. On the other hand, our understanding about human brain activity and possibilities is extending. Generally speaking, neuroscience opens new opportunities for people. Even though it is firstly connected with treatment, new treatment methods, on the other hand, the achievements in this field have a great influence on education.

Published: February 2022

Since the widespread introduction of Information and Communication Technology (ICT) in education the use of multimedia environments has increased substantially. This qualitative study analyse how teachers integrate multimedia tools into teaching and learning sequences (TLS) in science education. Four in-service teachers’ groups have been investigated across a 40 h teachers’ training course to analyse their pedagogical strategies and difficulties for introducing multimedia tools in science teaching. During the training program to discuss multimedia environments teachers (n=14) were invited to build teaching learning sequences (TLS) about some science content using multimedia tools. The results obtained through a content analysis suggest that these teachers are integrating multimedia tools mostly to enhance particular concepts and skills (integrated approach) than to innovate presentations (enhancement approach). In all cases teachers adopted structured tasks and in two of these they were not aware of the necessity to make explicit links between the multimedia tools and the other activities. Some difficulties related to pedagogical approaches and teachers’ knowledge are discussed. Key words: multimedia tools, science education, teachers’ knowledge, teachers’ pedagogical approaches.

The use of self-regulated learning strategies tend to have an impact on student learning and achievement; however, the nature of this relationship for primary science achievement needs further investigation. The purpose of this study was to examine the relationship between learning strategies used by primary students and their science achievement. The use of learning strategies was measured by the 50-item modified version of the Motivated Strategies for Learning Questionnaire (MSLQ) and the science achievement was measured by a test compiled from the released TIMSS items. Bivariate correlation analysis results showed that among the nine learning strategies that were investigated, seven of them were significantly associated with the science achievement. There were no correlations between peer learning and help seeking and achievement. Multiple regression analysis results showed that among the seven strategies, effort regulation, metacognitive self-regulation and critical thinking significantly contributed to the science achievement.

A SUSTENTABILIDADE SOCIAL, O PRINCÍPIO DA UNIVERSALIDADE DO SISTEMA ÚNICO DE SAÚDE E A JUDICIALIZAÇÃO DE MEDICAMENTOS
Authors: DEMARCHI CLOVIS , DREHER DE ARAUJO FLÁVIA
Published: February 2022

Este artigo faz uma relação entre a sustentabilidade social, o princípio da universalidade do Sistema Único de Saúde (SUS) e a judicialização de medicamentos. O direito à saúde, tratado como um direito social, que visa garantir o bem-estar físico, mental e social de toda uma população, enquadra-se na dimensão social da sustentabilidade. O princípio da universalidade, tratado inclusive pela Organização Mundial da Saúde (OMS), “propõe que sistemas de saúde priorizem serviços que ofereçam grandes ganhos em saúde a custo baixo e com evidência científica robusta de segurança e efetividade, ainda que isso implique não financiar tratamentos pouco custo-efetivos ou de natureza experimental”. Respeitando o princípio da universalidade a Constituição Federal estabelece que a saúde é um direito de todos e um dever do Estado, desde que os tratamentos de saúde oferecidos pelo SUS estejam previstos em políticas públicas de saúde. A concessão judicial de tratamentos de saúde não previstos nestas políticas públicas, desrespeita a noção de sustentabilidade social do direito à saúde uma vez que, ao usar o orçamento da saúde que deveria abranger o maior número possível de pessoas, aloca tais recursos para situações individuais, deixando a parcela mais vulnerável da população sob o risco de não ter seus direitos respeitados.
Palavras-Chave: Sustentabilidade social. Direito à saúde. Judicialização.
 
Abstract: This article relates the social sustainability concept with the universal health coverage principle of the Brazilian Public Health System and the judicialization of medicines. The right to health, seen as a fundamental social right, which ensures physical, mental and social well-being of the whole population, is placed in the social sustainability concept. The universal health coverage principle, analyzed by the World Health Organization, proposes that health systems coverage should offer the greatest total improvement in health at lower budget and considerer solid scientific effectiveness and security, even if this implies not financing treatments with low cost-benefit or experimental. Regarding the universal health coverage principle, the Brazilian Constitution establishes that the right to health should cover everyone and should be provided by the State, but this coverage should be limited by the public health policies. When justice provides to someone a medicine that is not included in these public health policies, it disrespects the social sustainability concept of the right to health, since it uses the public budget that should benefit as many people as possible, toward one only person, leaving the vulnerable population under the risk of not having its rights respected.

This study aimed to determine the students' motivation of non-English Department—intrinsic and extrinsic—in learning English. It was carried out at the second-grade students of the Quran Science and interpretation study program (IAT) academic year 2020/2021. This study employed descriptive-survey research. There were 34 students becoming the participants of this study.  The researchers employed the questionnaire, which consisted of twelve statements to get the data about students’ motivation. it was divided to nine statements about intrinsic motivation and three statements for extrinsic motivation. The data obtained revealed that for intrinsic motivations level, the students were at a high level of motivation with a total mean score of 4. 09 and for extrinsic motivation, the total mean score was 3.97, and it showed that students were also at high level of motivation. Thus, it can be summarized that the students have both intrinsic and extrinsic motivation in studying English although they were non-English Department students. Moreover, the students’ intrinsic motivation in learning English was higher than extrinsic motivation. It can be said that the students were able to control themselves to learn English, even though there was not much external motivation from lecturers or others. Regarding the result of this research, future researchers are expected to conduct depth research related to this topic. Moreover, the English lecturers who teach the students from the non-English department who are motivated should have good techniques and methods in teaching them, in the order they can achieve their goals in learning English.
The Role of Competitive Activities on Preschool Children Performance
Authors: Tsiakara Angeliki A. , Digelidis Nikolaos M.
Published: February 2022

It is well recognized the importance of preschool children understanding of a product goal or a process goal in a school activity and in which way the kind of the goal could affect children’s performance in this activity. As known, product goals determine the outcome of learning and lead students’ attention to the outcome rather than to the strategy or method that can lead to the result. Instead, the process goal refers to methods and strategies that lead students learn handling a specific task. Herein, 30 preschool children, at a mean age of 5 ½ years, participated in two different games, twice each with different goal each time (product goal/process goal). The results showed that preschool children exhibited better performance in both games when the goal was of product type. Moreover, in the case of a process goal, it was observed that children encouraged their classmate who played the game, while in case of a product goal they did not encourage their classmate, but they only counted his successful efforts. The results show that children understand the difference between process goal and product goal, enhancing their performance in case of product goals aiming to win. Nevertheless, previous studies which contacted in older children, under competitive learning environment where the goal of an activity emphasize to the outcome, showed that children brake their efforts, when they feel that they cannot win. According the obtained results, preschool teachers should avoid the product goals and emphasize to the process goals.

Published: February 2022

There are many channels which can be used for advertising – Google Ads, Facebook, Google Hotel Ads, Trivago, some of which allow direct communication with a single person, while other only allow to advertise to groups of people. A typical booking process through Google Ads looks as follows: the hotel creates an ad (potentially a personalized ad), a potential client searches for a hotel in Google, the ad is shown to the user, the user clicks on the ad and is redirected to the hotel’s website, and there makes a reservation. As the advertiser pays per click, the proper measure of the ad/offer performance is the average value per click. The main problem solved can be stated as follows: design hotel clients segmentation techniques coupled with automated offer generation methods allowing to maximize the value per click from an ad campaign.

The standard of care treatment for neovascular age-related macular degeneration, delivered as ocular injection, is based on anti-vascular endothelial growth factor (anti-VEGF). The course of treatment may need to be modified quickly for certain patients based on their response. Models that track both the concentration and the response to an anti-VEGF treatment are presented. The specific focus is to assess the existence of analytical solutions for the different types of models. Both an ODE-based model and a map-based model illustrate the dependence of the solution on various biological parameters and allow the measurement of patient-specific parameters from experimental data. A PDE-based model incorporates diffusive effects. The results are consistent with observed values, and could provide a framework for practitioners to understand the effect of the therapy on the progression of the disease in both responsive and non-responsive patients.
Center of Mass Offset Enhances the Selection of Transverse Gallop in High-Speed Running by Horses: A Modeling Study

Published: February 2022

Horses use the transverse gallop in high-speed running. However, different animals use different gaits, and the gait preference of horses remains largely unclear. Horses have fore-aft asymmetry in their body structure and their center of mass (CoM) is anteriorly located far from the center of the body. Since such a CoM offset affects the running dynamics, we hypothesize that the CoM offset of horses is important in gait selection. In order to verify our hypothesis and clarify the gait selection mechanisms by horses from a dynamic viewpoint, we developed a simple model with CoM offset and investigated its effects on running. Specifically, we numerically obtained periodic solutions and classified these solutions into six types of gaits, including the transverse gallop, based on the footfall pattern. Our results show that the transverse gallop is optimal when the CoM offset is located at the position estimated in horses. Our findings provide useful insight into the gait selection mechanisms in high-speed running of horses.

Published: February 2022

The regeneration defect of bone is a long-term physiological process after bone injuries. To accelerate the bone remodeling process, the combination of chemical and physical stimulations provides an efficient strategy to allow maturation and to functionalize osteoclasts and osteoblasts. This study aims to investigate the dual effects of a tricalcium phosphate (TCP)-based gelatin scaffold (GGT) in combination with electroacupuncture stimulation on the activation of osteoclasts and osteoblasts, as well as new bone regrowthin vitro and in vivo. We demonstrated that electrical stimulation changes the pH of a culture medium and activates osteoblasts and osteoclasts in anin vitroco-culture system. Furthermore, we showed that electroacupuncture stimulation can enhance osteogenesis and new bone regrowthin vivoand can upregulate the mechanism among parathyroid hormone intact (PTH-i), calcium, osteoclasts, and osteoblasts in the bone-defected rats. Those results showed the potential interest to combine the electroacupuncture technique with GGT scaffolds to improve bone remodeling after injury.

Published: February 2022

Background

The discrepancy between the high technical success rate and the relatively low clinical response rate of renal artery stenting (RAS) raises the importance to identify atherosclerotic renal artery stenosis (ARAS) patients who are most likely to benefit from RAS. This study aimed to investigate the feasibility and accuracy of blood oxygen level-dependent magnetic resonance imaging (BOLD-MRI) in predicting split renal function (SRF) improvement after RAS in patients with ARAS.

Methods

Thirty patients with severe ARAS who were treated with RAS were enrolled. Baseline cortical and medullary R2* values of each kidney were measured by BOLD-MRI, and each patient’s SRF was evaluated by nuclear renal dynamic imaging at baseline and 1-month follow-up.

Results

In total, 35 severe stenotic renal arteries of the 30 patients were analyzed. At 1-month follow-up, 34 kidneys (97.1%) of severe ARAS had acquired SRF. SRF improved in 12 kidneys of 10 patients. The cortical R2* and medullary R2* values in the SRF improvement kidneys were higher than those in the non-improvement kidneys (P ≤ 0.001). The area under the curve of medullary R2* was 0.879 (95% confidence interval [CI] 0.736–1.000). A medullary R2* value ≥29.1 s–1 was noted to provide good sensitivity (0.833, 95% CI 0.552–0.970) and specificity (0.864, 95% CI 0.667–0.953) in predicting SRF improvement. Medullary R2* value was the only independent predictor of SRF improvement in multivariable analysis (P = 0.034, OR 3.017, 95%CI 1.089–8.358).

Conclusion

This study showed that a BOLD-MRI medullary R2* value ≥29.1 s–1 was an excellent predictor of SRF improvement in patients with severe ARAS who underwent renal artery stenting.

Current predictive models for patients undergoing coronary angiography have complex parameters which limit their clinical application. Coronary catheterization reports that describe coronary lesions and the corresponding interventions provide information of the severity of the coronary artery disease and the completeness of the revascularization. This information is relevant for predicting patient prognosis. However, no predictive model has been constructed using the text content from coronary catheterization reports before.

Objective

To develop a deep learning model using text content from coronary catheterization reports to predict 5-year all-cause mortality and 5-year cardiovascular mortality for patients undergoing coronary angiography and to compare the performance of the model to the established clinical scores.

Method

This retrospective cohort study was conducted between January 1, 2006, and December 31, 2015. Patients admitted for coronary angiography were enrolled and followed up until August 2019. The main outcomes were 5-year all-cause mortality and 5-year cardiovascular mortality. In total, 11,576 coronary catheterization reports were collected. BioBERT (bidirectional encoder representations from transformers for biomedical text mining), which is a BERT-based model in the biomedical domain, was utilized to construct the model. The area under the receiver operating characteristic curve (AUC) was used to assess model performance. We also compared our results to the residual SYNTAX (SYNergy between PCI with TAXUS and Cardiac Surgery) score.

Results

The dataset was divided into the training (60%), validation (20%), and test (20%) sets. The mean age of the patients in each dataset was 65.5 ± 12.1, 65.4 ± 11.2, and 65.6 ± 11.2 years, respectively. A total of 1,411 (12.2%) patients died, and 664 (5.8%) patients died of cardiovascular causes within 5 years after coronary angiography. The best of our models had an AUC of 0.822 (95% CI, 0.790–0.855) for 5-year all-cause mortality, and an AUC of 0.858 (95% CI, 0.816–0.900) for 5-year cardiovascular mortality. We randomly selected 300 patients who underwent percutaneous coronary intervention (PCI), and our model outperformed the residual SYNTAX score in predicting 5-year all-cause mortality (AUC, 0.867 [95% CI, 0.813–0.921] vs. 0.590 [95% CI, 0.503–0.684]) and 5-year cardiovascular mortality (AUC, 0.880 [95% CI, 0.873–0.925] vs. 0.649 [95% CI, 0.535–0.764]), respectively, after PCI among these patients.

Conclusions

We developed a predictive model using text content from coronary catheterization reports to predict the 5-year mortality in patients undergoing coronary angiography. Since interventional cardiologists routinely write reports after procedures, our model can be easily implemented into the clinical setting.

Published: February 2022

Background

Acute myocardial infarction (AMI) is considered an acute coronary syndrome (ACS), which is caused by the death of myocardial cells after prolonged ischemia, and there is a high risk of sudden death during AMI. Therefore, the purpose of this study is to explore the relationship between thrombin activatable fibrinolysis inhibitor (TAFI) and AMI and provide evidence for their association and potentially the prevention of AMI.

Methods

There were 228 subjects included in this retrospective study, which included 78 AMI patients and 150 controls. The immune turbidimetry was used to measure TAFI concentration in the serum. Mann–Whitney U test was used to compare serum TAFI levels. The logistic regression analysis was used to construct a model of influencing factors of AMI. The dose-response relationship between serum TAFI level and AMI was explored by using the restricted cubic spline (RCS) functions combined with logistic regression analysis.

Results

The serum TAFI levels of the AMI group were higher than the control group’s (P = 0.003). The risk of AMI in the high-TAFI level group was 2.24 times higher than the low-TAFI level group (P = 0.007) and it was 2.74 times higher after adjustment of other risk factors (P = 0.025). According to the dose-response curve, the risk of AMI increased significantly with an increase of serum TAFI concentration (P = 0.0387).

Conclusion

Acute myocardial infarction patients had higher serum TAFI levels, and TAFI was an independent risk factor for AMI patients. Serum TAFI levels demonstrated a dose- dependent response to the risk of AMI. Our study provides evidence that TAFI could be used for risk stratification of AMI patients.

Published: February 2022

Objectives

To evaluate the usefulness of spectral detector CT (SDCT)-derived pulmonary perfusion maps and pulmonary parenchyma characteristics for the semiautomated classification of pulmonary hypertension (PH).

Methods

A total of 162 consecutive patients with right heart catheter (RHC)-proven PH of different aetiologies as defined by the current ESC/ERS guidelines who underwent CT pulmonary angiography (CTPA) on SDCT and 20 patients with an invasive rule-out of PH were included in this retrospective study. Semiautomatic lung segmentation into normal and malperfused areas based on iodine density (ID) as well as automatic, virtual non-contrast-based emphysema quantification were performed. Corresponding volumes, histogram features and the ID SkewnessPerfDef-Emphysema-Index (δ-index) accounting for the ratio of ID distribution in malperfused lung areas and the proportion of emphysematous lung parenchyma were computed and compared between groups.

Results

Patients with PH showed a significantly greater extent of malperfused lung areas as well as stronger and more homogenous perfusion defects. In group 3 and 4 patients, ID skewness revealed a significantly more homogenous ID distribution in perfusion defects than in all other subgroups. The δ-index allowed for further subclassification of subgroups 3 and 4 (p < 0.001), identifying patients with chronic thromboembolic PH (CTEPH, subgroup 4) with high accuracy (AUC: 0.92, 95%-CI, 0.85–0.99).

Conclusion

Abnormal pulmonary perfusion in PH can be detected and quantified by semiautomated SDCT-based pulmonary perfusion maps. ID skewness in malperfused lung areas, and the δ-index allow for a classification of PH subgroups, identifying groups 3 and 4 patients with high accuracy, independent of reader expertise.

Published: February 2022

Background

Despite solid evidence supporting the efficacy of electronic mental health (EMH) services, their acceptance among psychotherapists is limited and uptake rates remain low. However, the acceptance of different EMH services has yet barely been examined in future generations of psychotherapists in a differentiated manner. The aims of this study were (1) to elaborate the intention to use various EMH services for different application purposes and (2) to determine predictors of EMH service acceptance among psychotherapists in clinical training (PiT).

Materials and Methods

Our paper is based on a secondary data analysis of a cross-sectional survey. Respondents were recruited via recognized educational institutions for psychotherapy within Germany and the German-speaking part of Switzerland between June and July of 2020. The survey contained items on the intention to use different EMH services (i.e., guided and unguided programs, virtual reality, psychotherapy by telephone and videoconference) for various application purposes (i.e., prevention, treatment addition, treatment substitute, aftercare). Potential predictors of EMH service acceptance (e.g., barriers and advantages) were examined based on an extension of the Unified Theory of Acceptance and Use of Technology (UTAUT).

Results

Most of the n = 216 respondents were female (88.4%) and located in Germany (72.2%). General acceptance of EMH was moderate (M = 3.4, SD = 1.12, range 1–5), while acceptance of psychotherapy via videoconference was highest (M = 3.7, SD = 1.15) and acceptance of unguided programs was lowest (M = 2.55, SD = 1.14). There was an interaction effect of EMH service and application purpose (η2 = 0.21). Barriers and advantages both had a uniform influence on EMH service acceptance (Pr > 0.999), while impersonality, legal concerns, concerns about therapeutic alliance, simplified information provision, simplified contact maintenance, time flexibility, and geographic flexibility were significant predictors (all p < 0.05). Results showed that the extended UTAUT model was the best fitting model to predict EMH service acceptance (Pr > 0.999).

Conclusions

The intention to use different EMH services varied between application purposes among PiT. To increase acceptance of EMH services and reduce misconceptions, we identified predictors that should be addressed in future acceptance-facilitating interventions when educating PiT.
