Published: June 2022

Mindset plays a vital role in tackling the barriers to improving the preservice mathematics teachers’ (PMTs) conceptual understanding of problem-solving. As the COVID-19 pandemic has continued to pose a challenge, online learning has been adopted. This led this study to determining the PMTs’ mindset and level of conceptual understanding in problem-solving in an online learning environment utilising Google Classroom and the Khan Academy. A quantitative research design was employed specifically utilising a descriptive, comparative, and correlational design. Forty-five PMTs were chosen through simple random sampling and willingly took part in this study. The data was gathered using validated and reliable questionnaires and problem-solving tests. The data gathered was analysed using descriptive statistics, analysis of variance, and simple linear regression. The results revealed that the college admission test, specifically numerical proficiency, influences a strong mindset and a higher level of conceptual understanding in problem-solving. Additionally, this study shows that mindset predicts the levels of conceptual understanding in problem-solving in an online environment where PMTs with a growth mindset have the potential to solve math problems. The use of Google Classroom and the Khan Academy to aid online instruction is useful in the preparation of PMTs as future mathematics teachers and problem-solvers. Further studies may be conducted to validate these reports and to address the limitations of this study.

Authors: Vasanicova Petra , Jencova Sylvia , Gavurova Beata , Bacik Radovan
Published: June 2022

Coopetition has been the issue of various studies in different fields, but there is a research gap in examining coopetition within the tourism sector and destination management. This paper aims to determine whether there are internally homogeneous and externally heterogeneous groups of European Union countries regarding indicators of natural and cultural resources of the Travel and Tourism Competitiveness Index (TTCI), and thus subsequently identify the importance and possibilities of competition among countries within the tourism sector. Multidimensional scaling and cluster analysis are used to verify the research hypothesis, along with ten indicators of the fourth sub-index (Natural and Cultural Resources) of TTCI. The results of the cluster analysis led to a six-group solution. Italy, Spain, and France have the best position in terms of tourism competitiveness. The results show space for competition in the international tourism market. Even though EU countries are competitors at a global level, their cooperation could be beneficial to tourism development. The findings of this study can be helpful in planning and strategy development for tourism policymakers and destination management organizations but can also be used to develop various marketing strategies. Furthermore, cooperation between destinations will support the need for strategic flexibility in the tourism sector, as the diversity of tourism attractions will increase.

Existency, Role and Fading Local Wisdom of Tidal Farmer Community in Ciamis Regency
Authors: Setiawan Iwan , Kurnia Predi Nanda
Published: June 2022

The comprehensive and most successful modernization of agriculture in Indonesia occurs in rice farming, including its institutional aspects. In reality, in Lakbok District, local wisdom still plays an important role in rice farming in Tidal rice fields. This study aims to determine the existence and role of local wisdom in lowland rice cultivation in Tidal rice field and to find out the fading of local wisdom in the lowland rice farming system in Lakbok, Ciamis Regency. This qualitative research method and case study technique are conducted on indigenous people in Lakbok District, Ciamis Regency during 2018-2020. Four traditional leaders are selected as informants and interviewed in-depth, and 47 rice farmers are involved in the focus group discussion. Primary data are collected, selected, and coded, then analyzed dialectically and constructed visually into internalized patterns. The results reveal that local wisdom exists in the form of planting schedule (when to seed, plant, and harvest), water management, planting (cultivation techniques), land management and inheritance, harvest management, and post-harvest handling. These local rules that have been passed down from generation to generation are institutionalized collectively regarding traditional leaders (kasepuhan). Local wisdom exists and plays a role in the management of lowland rice farming systems and assists farmers in managing water, stabilizing production/productivity, and maintaining the integrity of paddy fields. However, its existence is increasingly eroded in the whole rice farming system (agribusiness). The recommendation is that the sustainability of local wisdom is largely determined by regeneration, internalization, and protection processes.

Aluminum Clusters (N=2-6) on CTF-0 Monolayer for Adsorption of Atrazine: Investigated by Density Functional Theory
Authors: Ibarra Rodríguez Marisol , Sánchez Mario
Published: June 2022

Abstract. We present a theoretical investigation of the structural characteristics and stabilities of neutral and positively charged aluminum clusters Aln n= 2-6 on covalent triazine frameworks (CTF-0). We found that clusters are adsorbed on the CTF-0 with adsorption energies of 26.32 – 91.53 kcal/mol. All calculations showed that the interaction between the aluminum cluster and CTF-0 is strong and prefers to adsorb in the central cavity of the monolayer with Al-C 2.03-2.92 Å and Al-N 1.89-2.12 Å bond formation. Next, we calculated the adsorption of an atrazine molecule on the [AlnCTF-0] n=2-6 systems. It is found that an atrazine molecule is physically adsorbed only on three systems, [AlnCTF-0] n=3-4,6 with adsorption energies in the range of 30.68 to 61.08 kcal/mol. The NBO analysis reveals that aluminum atoms accept electron density from nitrogen of atrazine molecule, but they also return electron density to the atrazine molecule. Although this result suggests that the [AlnCTF-0] n = 3-4,6 systems can be used as a promising candidate to remove the atrazine molecule.
 
Resumen. Presentamos una investigación teórica de las características estructurales y las estabilidades de los cúmulos de aluminio cargados positivamente y neutros Aln n = 2-6 en el fragmento de triazina covalente (CTF-0). Encontramos que los cúmulos se adsorben en el CTF-0 con energías de adsorción de 26.32 a 91.53 kcal/mol. Todos los cálculos mostraron que la interacción entre el cumulo de aluminio y CTF-0 es fuerte y prefiere adsorberse en la cavidad central de la monocapa con formación de enlaces Al-C 2.03-2.92 Å y Al-N 1.89-2.12 Å. Seguido, calculamos la adsorción de una molécula de atrazina en los sistemas [AlnCTF-0] n=2-6. Se encuentra que una molécula de atrazina se adsorbe físicamente sólo en tres sistemas, [AlnCTF-0] n=3-4,6 con energías de adsorción en el rango de 30.68 a 61.08 kcal/mol. El análisis NBO revela que los átomos de aluminio aceptan la densidad de electrones del nitrógeno de la molécula de atrazina, pero también devuelven densidad de electrones a la molécula de atrazina. Estos resultados sugieren que los sistemas [AlnCTF-0] n = 3-4,6 pueden usarse como candidatos prometedores para remover la molécula de atrazina.

Authors: Aras Andi , Zahrawati Fawziah , Busrah Zulfiqar , Nzobonimpa Claver
Published: June 2022

One goal of learning mathematics is to foster students’ critical thinking skills, but this has not been realized well in Indonesia. This study aims to produce a learning trajectory that can help students grow their critical thinking skills in studying quadrilaterals using the Burongko cake context. This study uses a design research method that comprises three stages, namely (1) preliminary design, (2) experimental design, and (3) retrospective analysis. This research was conducted at Madrasah Tsanawiyah As’adiyyah Bontouse with 25 students, nine males and 16 females of class VIII B. The results showed that this learning trajectory could improve students’ understanding of learning quadrilaterals with ease and fun because mathematical concepts are associated with students’ daily habits. The resulting learning trajectory is relevant to indicators of critical thinking skills, including interpretation, analysis, evaluation, and decision making. It was found that there was no significant difference in critical thinking skills between students who had high mathematical abilities and low mathematical abilities. Subjects with high mathematical abilities could carry out critical thinking processes to solve problems much better than subjects with low mathematical abilities. The results provide information about the use of local Bugis culture as a context of learning mathematics to improve students’ critical thinking.

Published: June 2022

This study is intended to result in instruction that will help pupils improve their mathematics understanding skills. The similarity of strategies in both the scientific and reciprocal teaching approaches makes it difficult to choose which approach is better. This investigation aims to investigate and explain (1) Improving pupils' mathematical understanding through comparison of scientific approaches and Reciprocal Teaching based on PAM; (2) The impact of the interaction between learning approaches with pupils' PAM on enriching pupils' mathematics understanding ability. It is a quasi-experimental research project that uses two experimental classes. The results of this study are (1) Pupils who learn through the scientific approach and pupils who learn through reciprocal teaching strategies based on PAM pupils have different mathematical thinking abilities, with the average value of improvement in the scientific approach class being more significant than the reciprocal teaching approach class; (2) Learning and pupils' PAM have no interaction effect. It means that learning in both experimental classes applies to all pupils overall in improving pupils' mathematical understanding ability. Based on the results of this study, this study implies that teachers can employ learning using a scientific approach as one of the learning options for pupils to increase their mathematical understanding abilities.
A learning trajectory of integer addition and subtraction using the kempreng game context
Authors: Salsabila Indri , Amir Mohammad Faizal , Wardana Mahardika Darmawan Kusuma
Published: June 2022

Traditional games can be used as a context to understand mathematical concepts. Many studies on learning trajectory (LT), which are set in the context of traditional games, have been carried out. However, no study focuses on using the context of the traditional kempreng game to facilitate primary students in understanding integer addition and subtraction. This research aims to design an LT through traditional game kempreng to help construct students' understanding and mathematical concepts through various activities that have been developed. This study uses design research with stages, namely preliminary design, teaching experiment, and retrospective analysis. This study produces LT which consists of five activities, namely: consisting of calculating addition points through the kempreng context, calculating subtraction (difference) through the kempreng context, performing additional operations on the “same” kempreng card, performing subtraction operations on “different” kempreng, and determining the results of addition or subtraction operations of number cards with the opposing group. In this study, LT set in the traditional game of kempreng can be used as a context in preparing learning designs that could stimulate students thinking in understanding the mathematical concepts of integer addition and subtraction. The impact of the research design also occurs on teachers. Learning becomes a student center, the teacher as a facilitator. The results of this study can have implications as one of the considerations for using contexts with real and cultural backgrounds to reduce or build a meaningful understanding of the concept of integer addition and subtraction for primary students.

Published: June 2022

Reflecting on PISA and TIMSS, international mathematical, reading, and science literacy assessments, the Indonesian government began implementing the Minimum Competency Assessment (MCA) for primary, secondary, and high school students. MCA demands the ability to solve daily life problems, one of which is geometry problems that require spatial ability. This research focused on describing spatial thinking ability used in numeracy competencies on geometry content. This research is descriptive with a qualitative approach. Thirty junior high school students in Malang, East Java, Indonesia, took the MCA preparation test and assessed their spatial thinking skills. The research was conducted in three stages: preparation, implementation, and analysis, and showed that three aspects of spatial ability, namely visualization, orientation, and relations, had not yet fully emerged. Some students cannot arrange the expected pattern. There are even students who ignore the geometric shapes requested. Students simplify drawing a hexagon with a quadrilateral, which are two different geometric objects, which leads to fatal errors. This study suggests that teachers emphasize learning mathematics that can train students' spatial thinking skills because it can lead to better mathematical understanding and performance.

Published: June 2022

Creativity is the highest order of thinking, which leads students to generate new ways to find a solution to many unpredictable problems in the future. Although there are many studies on creative thinking ability, no research focused on augmented reality and visualizer-verbalizer cognitive style in creative thinking ability. This study aims to describe creative thinking ability assisted with augmented reality view from visualizer-verbalizer cognitive style. This study used a qualitative descriptive approach. The subjects of this study were selected four students' 52 from the 10th grade. The process of selecting this subject was analyzed by the Rasch Model analysis using Winsteps software version 3.73. The data were collected using Visualizer-Verbalizer Questionnaire (VVQ), a creative thinking ability test assisted with augmented reality and interview. The final scale from the visualizer scale has a Cronbach alpha value of 0.67, while the verbalizer scale has a Cronbach alpha value of 0.66. The results show that the visualizer students meet all the indicators of creative thinking ability: fluency, flexibility, originality, and elaboration. While the verbalizer students only meet fluency indicators or fluency and originality indicators in creative thinking ability. Therefore, based on this research analysis, teachers can pay more attention to the students' cognitive style in creative thinking ability.

Authors: Wulandari Eva Yunida , Alyani Fitri
Published: June 2022

Online learning for students requires high self-regulated learning to maximize problem-solving skills, especially in fractional material. However, elementary school students have not widely seen self-regulated learning and problem-solving abilities. Therefore, this study aimed to determine the relationship between self-regulated learning and problem-solving skills, especially on fractions in online learning in fifth-grade elementary school. This research is included in a quantitative study that uses a sample of fifth-grade students in an elementary school in Depok City. A sample of 122 students (N = 67 female, N = 55 male) was obtained using a non-probability sampling technique. Data collection techniques were carried out through the distribution of a self-regulated learning questionnaire with as many as 29 statements and a problem-solving ability test instrument with as many as eight questions. The data obtained were measured and analyzed using Rasch modeling and assisted by Winsteps software version 4.4.2. Furthermore, the correlation and Effect Size tests were carried out to determine the relationship and influence between variables. The results showed a significant and interrelated relationship between self-regulated learning and problem-solving ability. In other words, the higher the quality of independence in students, the higher the quality of problem-solving abilities they have, and vice versa. That way, it can encourage students to maximize self-regulated learning when learning online to help improve problem-solving skills in learning.
A review of ECG signal filtering approaches
Authors: Anas Fouad Ahmed  , Mohammed K Al-Obaidi
Published: June 2022

An electrocardiogram (ECG) quantifies the electrical activity of the heart to screen for different heart diseases, although it can be impacted by noise. ECG signal filtering is a crucial pre-processing step that reduces noise and emphasizes the characteristic waves in ECG data. In real-world applications, the ECG signal is contaminated by different types of noise. Separating the desired signal from noises produced by artifacts such as muscle noise, power line interference (PLI), baseline wandering (BW), and motion artifacts (MA) is a complicated task. In this paper, a quick review of various ECG signal denoising methods is introduced.
A case study to assess the effects of the Exo-pulse neuromodulation suit on pain, fatigue and sleep patterns of an individual diagnosed with CFS/ME
Authors: Jörgen Sandell
Published: June 2022

The Exopulse suit was initially an approach to reduce spasticity and improve motor function in individuals with lesions in the CNS. Anecdotal findings from Exopulse users suggest that it could benefit people with pain syndromes, fatigue, and disturbed sleeping patterns. The Exopulse neuromodulation suit was programmed to apply multi-site afferent electrical stimulation and subsequently worn for one hour daily for thirty days. The one-hour session was done at the same time every morning, 9 AM to 10 AM, while the patient was lying in bed. One-hour Exopulse treatments consistently led to improvements in activity and sleep patterns. Diary records indicate that results carried over into the following day, which may indicate a training effect. All baseline scores were improved in self-assessments and objective measurements. The patient's parents commented on the increased interaction with friends and family, the increased planning ahead, and decreased agitation. CFS/ME is a condition in which performance and alertness can change due to environmental and internal factors. The results of this single Case Study design need to be approached cautiously.

Published: June 2022

Raḥmān (rḥmn) kelimesinin oldukça uzun bir geçmişe sahip olduğu ifade edilmiştir. Suriye ve Güney Arabistan’daki çok tanrılı dinlerin yanı sıra Yahudilik, Hıristiyanlık ve İslam gibi tek tanrılı dinler tarafından kelimenin hangi çerçevede nasıl kullanıldığını incelemek ve kökeni hakkında bilgi verebilmek adına çalışmamızın önemli birtakım veriler sunacağı kanaatini taşımaktayız. Raḥmān kelimesinin en eski formu olarak kabul edilen rḥmn’ye pagan metinleri arasında yer alan Tell Fekherye ve Palmira Kitabeleri başta olmak üzere Ahikar’ın Öğütleri’nde rastlanmaktadır. Tevrat ve İncil’in yanı sıra Ma’arib ve Murayghan Kitabeleri gibi bazı Yahudi ve Hıristiyan metinlerinde, ayrıca Cahiliye Arap şiiri ve Kur’ân’ı Kerîm’de Raḥmān kelimesinin kullanıldığı görülmektedir. Çalışmamız, pagan bir ortamda doğduğu düşünülen Raḥmān’ın, ilerleyen zamanlarda Yahudi ve Hıristiyan bir bağlama dönüşmesinin arka planını, ayrıca Cahiliye Arap şiiri ve Kur’ân’ı Kerîm’de hangi anlamlarda ve nasıl kullanıldığını ortaya koymaya yönelik olacaktır.

An Integrated Approach to the Treatment of Pulmonary Embolism: Current State of the Problem
Authors: Khrebtiy Yaroslav V.
Published: June 2022

The aim. Treatment of venous thromboembolism remains perhaps the most challenging problem of modern phlebology. The aim of our study was to analyze current data and guidelines on the use of surgical and minimally invasive approaches in the treatment of pulmonary embolism (PE) and to compare these with our own results.

Materials and methods. The results of treatment of 168 patients with PE, who underwent inpatient treatment at the clinic from 2009 to 2021, were analyzed. Among them, 162 (96%) patients had deep vein thrombosis, in 6 patients the cause of PE could not be identified. Recurrent PE was observed in 2 patients. PE with a high risk of death was observed in 51 (30.3%) patients, with a medium and low risk of death in 117 patients (69.6%).

Systemic thrombolysis was performed in 44 (26%) cases. In 5 (2.9%) cases, vena cava filters were implanted. One (0.6%) patient underwent aspiration thrombectomy of the pulmonary artery using an Aspirex catheter. Two (1.1%) patients underwent pulmonary artery thrombectomy using an artificial circulation device.

Results. Significant improvement in patients treated with thrombolytic therapy was observed in 40 (92.8%) cases. After surgical treatment of PE, significant improvement was observed in 100% of cases, 2 patients after PE showed complete de-obstruction of the pulmonary artery. No hemorrhagic complications were observed during the study period. No fatalities were reported. No recurrent PE was observed during the study period.

Conclusions. The choice of treatment for PE is determined by the degree of the impact on the pulmonary tract, the stability of the patient’s condition, indicators of dysfunction of the right heart, the period from the onset of the disease, the risk of death.

The use of aspiration thrombectomy using an Aspirex catheter (Straub, USA) and pulmonary artery embolectomy in the absence of thrombolytic therapy allows to obtain satisfactory results in patients with PE.
Determining the Epistemological Obstacles Regarding the Concepts of Infinity, Undefined and Uncertainty

Bu sonsuz, belirsiz ve tanımsız işlemlere verilen cevapların ve bu kavramlara ait tanımların incelenerek kavramlara dair epistemolojik engellerin belirlenmesi amaçlanmıştır. Bu bağlamda eğitim fakültesinde ve fen fakültesinde öğrenim gören matematik öğrencilerinin belirtilen kavramlara dair algılarından yola çıkılarak epistemolojik engelleri belirlenmiştir. Bu çalışmanın modeli, temel nitel araştırmadır. Çalışma grubunu Eğitim Fakültesi’nde ve Fen Fakültesi’nde öğrenim görmekte olan 71 öğrenci oluşturmaktadır. Çalışmanın verileri araştırmacılar tarafından hazırlanan ve iki bölümden oluşan test vasıtasıyla elde edilmiştir. Sonsuzluk, tanımsızlık ve belirsizlik kavramlarıyla ilgili epistemolojik engelleri belirlemek amacıyla veriler betimsel analiz tekniği kullanılarak çözümlenmiştir. Çalışma sonucunda öğrencilerin günlük hayat deneyimleri yoluyla edindikleri birincil sezgilerinin lisans eğitimi almalarına rağmen sonsuzluk algılarını çok fazla değiştirmediği görülmüştür. Öğrencilerin tanımsız, belirsiz kavramlarını karıştırdığı ve sonsuzla yapılan işlemlerin belirsiz olduğunu düşündükleri tespit edilmiştir. Matematik tarihinde kavramların gelişim süreci ve bu süreçte matematikçilerin yaşadıkları zorluklar göz önüne alınarak matematik öğrencileri ve öğretmen adayları daha çok bilgilendirilebilirler. Bu amaçla lisans öğretim programlarında olan Matematik Tarihi dersleri, kavramların gelişim süreci ve yaşanan zorluklar hakkında farkındalıklarının artacağı şekilde düzenlenerek öğrencilere sunulabilir. Böylece gelişimleri yüzyıllar alan kavramlar farazi bir ders içeriği olarak kalmak yerine öğrencilerin profesyonel hayatlarında kullanabilecekleri olgular haline gelebilirler
