Published: September 2022

CASK is a unique membrane-associated guanylate kinase (MAGUK) because of its Ca2+/calmodulin-dependent kinase (CaMK) domain. We describe four male patients with a severe neurodevelopmental disorder with microcephaly carrying missense variants affecting the CaMK domain. One boy who carried the p.E115K variant and died at an early age showed pontocerebellar hypoplasia (PCH) in addition to microcephaly, thus exhibiting the classical MICPCH phenotype observed in individuals with CASK loss-of-function variants. All four variants selectively weaken the interaction of CASK with Liprin-α2, a component of the presynaptic active zone. Liprin-α proteins form spherical phase-separated condensates, which we observe here in Liprin-α2 overexpressing HEK293T cells. Large Liprin-α2 clusters were also observed in transfected primary-cultured neurons. Cluster formation of Liprin-α2 is reversed in the presence of CASK; this is associated with altered phosphorylation of Liprin-α2. The p.E115K variant fails to interfere with condensate formation. As the individual carrying this variant had the severe MICPCH disorder, we suggest that regulation of Liprin-α2–mediated phase condensate formation is a new functional feature of CASK which must be maintained to prevent PCH.

Bianchi Type V Tsallis Holographic Dark Energy Model with Hybrid Expansion Law
Authors: Das Manash , Mahanta Chandra
Published: September 2022

A number of recent cosmological observations have provided increasing evidence that currently the universe is undergoing a phase of accelerated expansion, the root cause of which is supposed to be due to an exotic component of the universe with large negative pressure, dubbed dark energy. Out of the various candidates of dark energy proposed in the literature, the holographic dark energy emerged from the Holographic Principle is drawing much attention in the research field. In this paper, we investigate a spatially homogeneous and anisotropic Bianchi Type V space-time filled with non-interacting Tsallis holographic dark energy (THDE) with Hubble horizon as the IR cutoff and pressureless cold dark matter within the framework of General Relativity. Exact solutions of the Einstein field equations are obtained by considering the average scale factor to be a combination of a power law and an exponential law, the so called hybrid expansion law first proposed by Akarsu et al. (2014). We study the cosmological dynamics of various models for different values of the non-additive parameter that appeared in the Tsallis entropy and that for that appeared in the exponential function of the hybrid expansion law. We find that our model exhibits present cosmological scenario.

Published: September 2022

In this present study, we model Eckart-Hellmann Potential (EHP) to interact in a quark-antiquark system. The solutions of the Schrödinger equation are obtained with EHP using the Nikiforov-Uvarov method. The energy equation and normalized wave function were obtained. The masses of the heavy mesons such as charmonium (cc-) and bottomonium (bb-) for different quantum numbers were predicted using the energy equation. Also, the partition function was calculated from the energy equation, thereafter other thermal properties such as mean energy, free energy, entropy, and specific heat capacity were obtained. The results obtained showed an improvement when compared with the work of other researchers and excellently agreed with experimental data.

The state of liquid radioactive wastes (LRW) management at Ukrainian Nuclear Power Plants (NPPs) is characterized by the lack of a completed technological cycle from processing to obtaining the final product suitable for further long-term storage or disposal. As a result, the storage tanks for bottoms residue (BR) are 65-75% full (Zaporozhye and South-Ukrainian NPPs), and the resource for placing molten salt at Zaporizhzhya NPP (92.7%) is close to exhaustion [1]. Therefore, the development of technologies and materials for NPP LRW solidification is an urgent need and aims to ensure the processing of LRW to a solid state that will meet the acceptance criteria for disposal in centralized storage facilities. One of the effective methods of LRW solidification is their vitrification. The main advantage of vitrification is that during the vitrification process the volume of waste is reduced by several times and this saves expensive storage space [2, 3]. The purpose of this work is to calculate the absorbed dose that borosilicate glass matrices with included bottoms residue will accumulate over 300 years of storage, and to study the effect of simulated X-ray irradiation on their physical and mechanical properties.

Published: September 2022

Protein aggregation into highly ordered supramolecular aggregates is the hallmark of many degenerative diseases including the neurological disorders (Parkinson’s, Alzheimer’s, and Huntington’s diseases), type II diabetes, systemic amyloidosis, spongiform encephalopathies, etc. One of the simplest and effective methods for the identification and characterization of amyloid fibrils in vitro and the visualization of amyloid inclusions in vivo is based on the use of probes sensitive to the beta-pleated motifs. In the attempt to design new amyloid-sensing dyes or to optimization the existing molecules, it is crucial to have the sufficient knowledge of the molecular and atomic levels interactions in the binding sites. Among the especially useful methods available to provide the atomic-level insights into the mechanisms of various types of biomolecular interactions is molecular docking technique. In the present study, the molecular docking tool has been employed to investigate the interactions between the monomethine cyanine dyes and the lysozyme amyloid fibrils constructed from the K-peptide of lysozyme, GILQINSRW (residues 54–62 of the wild-type protein). Using the AutoDOCK and the protein-ligand interaction profiler PLIP it was found: i) monomethines interact with the fibril surface (with the aromatic residues on the top of β-sheet or with the edges of the β-sheet); ii) the dye binding is governed by the hydrophobic interactions, salt bridges and the hydrogen bonds between the aliphatic substituents on the nitrogen atom of benzothiazole part of dye molecules and the lysozyme amyloid fibril; iii) the variations in the cyanine structure and in the lysozyme amiloid twisting didn’t insert significant effect on the binding mode of cyanines.

Authors: Marcus Lloyde George , Nora Innocent-George
Published: September 2022

First-In-First-Out cores (FIFOs) are memory storage elements that are used in digital systems for buffering data through a system for later processing. This paper presents the design and implementation of a General Purpose FIFO Core which allows adjustment of the capacity along with the size of each data word. Status indicators were provided to indicate whether or not the FIFO was empty, half-full, or full. The number of data words stored in the FIFO was also indicated by designated output ports of the system. A status flag was also available to indicate when the size reached a predetermined threshold value. A separate interface was provided that allowed the data at any address to be accessed for reading. It was also possible to write a data word to the back of the FIFO while another data word was read from the front simultaneously. The FSM-D architectural model was applied to the design of the FIFO Core and the implementation was done in VHDL using the Xilinx ISE 14.7. The implemented core was simulated using ISim Logic Simulator of the Xilinx ISE platform, and it was found that the system core behaved as specified by the test cases.

Study of carbon dioxide corrosion products by the X-ray diffraction method
Authors: Vagapov R. K. , Mikhalkina O. G.
Published: September 2022

The internal carbon dioxide corrosion is one of the most common types of corrosion in the gas fields development. The results of studying the composition of carbon dioxide corrosion products by X-ray diffraction method are presented. FeCO3 is the main product resulting from dissolution of steel upon carbon dioxide corrosion. Siderite is characterized by the phenomenon of isomorphism in the crystal structure (a change in the chemical composition of the phase at the same crystal structure). In this case, some of the iron ions in FeCO3 can be replaced by manganese, calcium, and magnesium ions. It is shown that phases of the precipitates of non-stoichiometric composition (CaxMgyMnzFe)CO3 thus formed are poorly crystallized which is attributed to the presence of defects in the crystal structure. They will exhibit inferior protective properties compared to stoichiometric FeCO3. The film of FeCO3 is packed, uniformly distributed and tightly adhering to the steel surface. An analysis of the diffraction patterns revealed a good crystallization of FeCO3. The shape of FeCO3 particles tends to a regular hexagonal habitus. The results obtained can be used in studying the resistance of corrosion products formed on the internal surfaces of gas production equipment under aggressive conditions in the presence of CO2 in produced and transported hydrocarbons.

Published: September 2022

Anemia is a significant public health concern in pregnant women and women of reproductive age globally. The prevalence of anemia in Thailand was approximately 36.7%. Common causes of anemia were iron deficiency anemia (IDA) and beta-thalassemia trait (BTT). World Health Organization (WHO) recommends that dietary adjustments focusing on iron-rich foods foster the improvement of IDA and IDA with BTT. This study aimed to evaluate the effect of nutrition counselling in pregnant women with IDA on anemia parameters and dietary intake records. Retrospective data were obtained from the Division of Nutrition and Antenatal Care (ANC) Clinic at Bamrasnaradura Infectious Diseases Institute (BIDI) in Nonthaburi, Thailand. Nutrition Care Process Model was used in nutrition service at BIDI. During the second trimester, nutrition counselling was provided at the ANC Clinic by a dietitian routinely based on WHO guidelines for nutritional anemia. The anemia parameters and dietary intake records were recorded during ANC visits at the second and third trimesters. A paired t-test was used to evaluate differences within each group. Collected data from 61 pregnant women with anemia were analyzed (IDA: 55; BTT: 6). In the third trimester, the changes in hematocrit levels were significantly high in both IDA (p ≤ 0.001) and BTT groups (p = 0.016). In addition, the improvement in daily energy consumption and iron-rich foods was significantly observed in both groups (p ≤ 0.001). In conclusion, the delivery of nutrition counselling focusing on iron-rich foods significantly enhanced IDA parameters and eating behaviours, including increased hematocrit levels, and improved daily energy intake and iron-rich foods intake among pregnant women with anemia.

Authors: DAĞ Mustafa
Published: September 2022

Mut Hükümet Konağı altında hapishane olarak kullanılan mekân, fiziki şartları itibariyle hapishane vasfından uzak olmakla birlikte daha çok zindan (mahbes) olarak kullanılmıştır. Bu nedenden dolayı İçel İli Mutasarrıflığı tarafından merkezi yönetimden bir hapishanenin inşa edilmesi istenmiştir. Bu talebe 1914 yılında cevap verilerek inşa çalışmaları başlatılmıştır. Bu çalışmada Mut Hapishanesi’nin fiziki yapısının ıslahına yönelik tadilat çalışmaları, mahkumların tutukluluk türlerinin ve suç türlerinin dağılımına dair incelemelerde bulunulmuştur. Ayrıca hapishanede bulunan mahkûmların sağlık durumları, yiyecek ihtiyacının karşılanması ve hapishane görevlilerine dair bilgiler aktarılmıştır. Çalışmada Mut Hapishanesi’ne odaklanılarak imparatorluk genelinde hapishanelere yönelik devam eden reform çalışmalarının kazaya yansımaları incelenmeye çalışılmıştır. Genel olarak 19. yüzyıl sonları ile 20. yüzyıl başlarını kapsayan çalışmada Başbakanlık Osmanlı Arşivi ile telif eserlerden istifade edilmiştir. Çalışma neticesinde, kazada mahbes veya zindandan modern hapishaneye geçiş aşamasında zorlukların yaşandığı, yapının barınma açısından yetersiz olmasının yanı sıra sıhhi açıdan da elverişli olmadığı saptanmıştır. Görevli hapishane personelinin ise nicelik ve nitelik açısından yetersiz olduğu tespit edilmiştir. Hapishanenin fiziki yapısının ıslahına yönelik mahalli ve merkezi yönetim tarafından sağlanan bütçelerle giderilmeye çalışılmıştır.

Published: September 2022

This study attempts to restructure teaching, learning and evaluation guidelines in the national mathematics curriculum based on a group of experts’ opinion collected by conducting a survey and focused-group discussions. Three key points of distance learning, mathematical competence reinforcement, and future-oriented mathematics education were drawn from the literature to be investigated. Semantic network analyses were used to extract significant topics and meanings from the survey data. We further investigated experts’ suggestions in their vivid voices on reforming teaching, learning, and evaluation guidelines. The results suggest that it is necessary to provide detailed information on how to utilize distance learning environment with specific guides to new technologies including various platforms for building effective teaching, learning, and evaluation. Secondly, it is suggested to provide clarified concepts and specific components of mathematical competence with differentiation by school level. Thirdly, majority of experts pointed out the necessity of reinforcing process-oriented assessments and adaptive learning. The findings raised an issue of balancing between pursuing teacher autonomy and providing detailed guidelines in the national mathematics curriculum. Further findings and implications are discussed in terms of possible innovations and constraints in teaching, learning, and evaluation policies of the mathematics curriculum document.
A Critical Suggestion on Finance for High School
Authors:   The Korea Society Of Educational Studies In Mathematics, Cho Seung Mo
Published: September 2022

In this article, we have analyzed the financial contents in high school , first introduced by 2015 Amended Curriculum, from the curricular integration perspective by comparing them with those in 2020  by Financial Supervisory Service and Korea Institute for Curriculum and Evaluation, 2015 , 2015 , and 2015 . Through such analysis, we have pointed out some limitations of the financial contents in high school  and have offered an alternative for them. The limitations we have found are as follows: firstly, high school  is not well integrated to  and the other subjects because it only deals with savings but not investments while the others deal with both. Secondly, it confuses pensions and annuities causing misconception. Thirdly, its contents on annuities and perpetuities are not realistic. As a concrete alternative for such criticism, we have suggested that the subject should include valuation of stocks and bonds instead of annuities and perpetuities. And we have further shown that we do not need additional mathematical concepts in this case because valuation of stocks and bonds is also an application of geometric series and infinite geometric series just as that of annuities and perpetuities and that we have the additional educational benefit of enhancing integration with the differentiation chapter in the subject by differentiating bond prices with the differentiating techniques allowed in the subject.
Development and Application of Meta-affect Learning Strategies in Mathematics
Authors:   The Korea Society Of Educational Studies In Mathematics, Kim Sun Hee
Published: September 2022

This study developed meta-affect learning strategies in mathematics and applied them to mathematics classes. The meta-affect strategies are consisted of affective planning, monitoring, and reflection. The affective planning is to represent emotions that student expects, the affective monitoring is to check his/her affect in the process of solving problems, and the affective reflection is to look back and compare the emotions before and after mathematical activities, and to write a math emotion diary. As a result of applying the meta-affect strategies 12-14 times to 66 first graders in middle school, students’ affective achievement in mathematics was improved later than before the experiment, especially in value recognition and confidence. Meta-affect was also improved compared to before the experiment, especially in affective regulation, using and awareness. In the texts written by students about the meta-affect strategy experience, the awareness and use of affect were remarkable. Through this study, it was suggested that more studies on the development and application of meta-affect strategies should be conducted in the future, since meta-affect can be taught.

Published: September 2022

In this study, first and second-year high school math textbooks in France, which are actively introducing algorithms and programming as the content area of the mathematics curriculum, were analyzed. We looked at how algorithms and programming were used by areas such as algebra, geometry, and analysis, and analyzed the types of coding languages used and types of tasks. As a result of the analysis, algorithms and programming were used in all content areas in French textbooks, and text-based codes and pseudocodes were mainly used. In addition, it was confirmed that algorithms and programming can be dealt with in mathematical tasks in various forms, such as interpretation/modification/writing of code, execution and problem solving, and reflection. Based on the analysis results, implications for the introduction of algorithms in the mathematics curriculum were presented.

Authors:   The Korea Society Of Educational Studies In Mathematics, Suh Heejoo
Published: September 2022

Competency-based teaching should be promoted to prepare students for future society. Teachers, however, experience difficulty with teaching competency. Research on curriculum materials, including teaching guides, suggested that they could provide ample opportunity for teachers’ professional development, when carefully designed to be educative. The current study sought to understand educative opportunities for competency teaching presented in high school mathematics teaching guides. For the analysis, educative curriculum material was used as a theoretical framework. The results showed that the teaching guides provide supports for limited kinds of educative opportunities only. Similar patterns were observed through out each units from the curriculum. In addition, the range covered by each kind of support was narrow, curriculum designers’ intentions are not communicated in most cases, and instructions for implementations are often omitted. These findings indicate that high school teaching guides require significant amount of revision. To make such revision happen, redesigning curriculum writing process might be necessary.
Longitudinal Analysis on Probability and Chance in Elementary School Mathematics Curriculums and Textbooks
Authors:   The Korea Society Of Educational Studies In Mathematics, Chang Hyewon
Published: September 2022

Probability is characterized by uncertainty and chance, unlike most topics of school mathematics based on causality, and causes difficulties in teaching and learning due to conceptually various aspects. The purpose of this study is to identify changes and to check the direction of ’probability and chance’ in elementary school mathematics through longitudinal analyses of previous curriculums, textbooks, and coherence between curriculums and textbooks. As a result of the analyses, probability-related contents in the curriculums went through the 3rd introduction period, the establishment period of 4th~2007 revision, and the transition period of 2009 revision~2015 revision. As for textbooks, they underwent the 3rd dealing with the most diverse topics, the 4th~6th focusing on the number of cases, the 7th~2007 revision using the word ‘probability’ and including a few probability experiments, and the 2009 revision~2015 revision focusing on the chance. The coherence between curriculums and their textbooks is relatively good, but there are some factors that were insufficient to implement achievement standards, and there are several contents included in the textbooks but not explicitly mentioned in the curriculums. Based on these results, some implications for curriculum and textbooks were discussed.

Published: September 2022

The purpose of this study is to analyze teachers' perceptions about the mathematical competency of the 2015 revised curriculum. To this end, 42 high school mathematics teachers were asked to describe mathematical competencies in their own words. It was analyzed using semantic network analysis. In addition, the questionnaire was also conducted on the competencies that were considered important or not important in mathematics classes, and the reasons were analyzed and categorized by competencies. As a result of comparing teachers' responses to competencies and the description of the curriculum, information processing showed high agreement, but creativity and integration, attitude and practice showed low agreement. Also, teachers lacked understanding of some sub-elements of each competency. Teachers recognized problem solving as the most important competency in school mathematics. creativity and integration and information processing were mainly mentioned as competencies that were not considered important in class, but the reasons were different. Based on the main results, implications for mathematics teaching and learning were presented.

Published: September 2022

The aim of this study is to explore how to restructure the probability content standards in the national mathematics curriculum by pursuing the goals of developing probabilistic thinking competence and probabilistic problem solving. We named the perspective pursuing these goals as Data-Driven Probabilistic Education (DDPE) in that data sensitivity plays a significant role in probabilistic thinking and problem solving, and moreover relations between data and probability matter in statistics and machine learning fields. We further investigated into how to facilitate probabilistic thinking and probabilistic problem solving as well as what to adapt the meaning or grounding sense of the two major goals in the context of DDPE. Findings suggested some alterations to be made in the content standards and directions of teaching and learning in the curriculum document. First, to understand the probability concept based on data sensitivity, to understand randomness, and to solve probabilistic problems using modelling approach are suggested to be included in the contend standards. Second, we suggest to include contexts in which decisions about risk are made in the teaching and learning directions to enhance competence of dealing with volatility and uncertainty using probabilistic thinking competence. Third, rather than writing general statements on using technological tools, it is suggested to present specific ways or procedures of probability simulation using a computer in relation to understanding stages of probability concepts and solving probabilistic problems as guides to teaching and learning to realize DDPE.

Kelompok Pembudidaya Ikan Fish Under Crew berlokasi di Desa Pulau Semambu yang berdiri sejak tahun 2016 dengan komoditas ikan antara lain tambakan. Ikan tambakan yang dibudidaya sudah dapat merespons pakan buatan yang diberikan. Namun, pemanfaatan pakan oleh ikan tambakan tersebut masih belum efisien. Hal ini menjadi permasalahan yang dihadapi oleh pembudidaya ikan, termasuk di kelompok pembudidaya ikan Fish Under Crew. Penambahan enzim papain pada pakan dapat meningkatkan kecernaan pakan sehingga ikan dapat memanfaatkan pakan lebih efisien. Tujuan dari kegiatan pengabdian pada masyarakat ini adalah mengaplikasikan penggunaan enzim papain dalam pakan buatan untuk meningkatkan kecernaan pakan dan pengaruhnya terhadap pertumbuhan dan produksi ikan tambakan. Metode kegiatan berupa: 1) sosialisasi kegiatan, 2) penyuluhan terhadap terhadap anggota kelompok dan masyarakat di Desa Pulau Semambu, 3) pemberian bantuan berupa dua kolam terpal dengan kerangka besi beserta kelengkapannya, 4) Aplikasi enzim papan pada ikan melalui kegiatan pemeliharaan ikan selama 1 bulan, dengan menggunakan dua perlakuan yaitu perlakuan 0% enzim papain dalam pakan sebagai kontrol (P0) dan 0,75% enzim papain dalam pakan (P1). Sosialiasi dan penyuluhan dilaksanakan dengan melibatkan anggota kelompok dan masyarakat di Desa Pulau Semambu. Masyarakat mamahami materi penyuluhan yang disampaikan dan sangat antusias untuk mengaplikasikannya dalam kegiatan budidaya yang mereka lakukan yang dibuktikan dengan tanya jawab yang sangat interaktif selama sesi diskusi serta jawaban dari kuisioner yang diberikan pada peserta. Bantuan kolam diterima oleh anggota kelompok, didampingi oleh aparat desa dan pengurus Bumdesma. Pada pemeliharaan ikan dengan mengaplikasikan penambahan enzim papain pada pakan memberikan laju pertumbuhan mutlak yang lebih tinggi (pertumbuhan bobot mutlak 0,41 g dan panjang mutlak 0,56 cm) dibandingkan pakan komersial tanpa penambahan enzim papain. Berdasarkan kegiatan yang telah dilakukan, UPR Fish Under Crew telah mengaplikasikan penambahan enzim papain pada pakan untuk ikan tambakan. Hasil yang diperoleh dapat meningkatkan pertumbuhan ikan tambakan yang dipelihara dan penggunaan pakan lebih efisien.

Los sistemas agroforestales (SAF’s) de café tienen un alto potencial en la captura de carbono (C) gracias a la gran diversidad de especies leñosas usadas como sombra. El objetivo del presente estudio fue evaluar el potencial de captura de carbono en la biomasa vegetal aérea, mantillo y la materia edáfica en diferentes profundidades de suelo en cinco diferentes SAF’s de café en la región cafetalera de Huatusco, Veracruz, México. Los sistemas agroforestales estudiados fueron: a pleno sol (03.PSC-MZ, 04.PSC-ZI), especializados (05.ESP-MZ, 06.ESP-MZ, 07.ESP-CH) y se compararon con un bosque mesófilo de montaña CRUO (02.BMM-CH) y un potrero (01.POT-TH). El SAF con el mayor contenido de C en biomasa aérea, estimado con ecuaciones alométricas, fue el 05.ESP-MZ, con 373.75 Mg ha-1, seguido del 07.ESP-CH con 231.88 Mg ha-1, 04.PSC-ZI con 123.96 Mg ha-1, 03.PSC-MZ con 61.08 Mg ha-1, 06.ESP-MZ con 45.95 Mg ha-1, 02.BMM-CH 456.64 Mg ha-1 y 01.POT-TH 3.14 Mg ha-1. Respecto al C orgánico total el sistema 05.ESP-MZ obtuvo el mayor valor con 477.54 Mg ha-1 y el 06.ESP-MZ el menor con 108 Mg ha-1. La implementación y conservación de los SAF del café es vital ya que contribuye a mitigar el impacto ambiental negativo como las emisiones de CO2 a la atmósfera, compactación del suelo y pérdida de biodiversidad en flora y fauna que otros sistemas productivos han ocasionado.

En la actualidad existen investigaciones sobre los diferentes efectos de nanomateriales en la agricultura para mejorar la germinación y la productividad de los cultivos, con la finalidad de garantizar la sostenibilidad económica y el uso eficiente de los recursos de producción en la agricultura. Las nanopartículas de ZnO aplicadas en este estudio fueron sintetizadas por un método de precipitación química y su caracterización se realizó por (XRD), (SEM), espectroscopía UV-visible y (FTIR). Se determinó el efecto sobre la germinación de semillas de lechuga (Lactuca sativa) por medio de un diseño completamente al azar con cinco tratamientos de NPs-ZnO y un tratamiento control cada uno con cuatro repeticiones. Se midieron índices fisiológicos, se cuantificó el contenido de clorofila y carotenoides, y el contenido de compuestos fenólicos en las plántulas de lechuga. Los resultados indican que aplicando dosis de 50 mg L-1 NPs-ZnO, se lograron mayores valores del porcentaje de germinación (36.97%), peso fresco de plúmula (23.91%), peso fresco de radícula (63.25%) y longitud de radícula (50.58%) respecto a los grupos control. Asimismo, se incrementó el contenido de fenoles totales (207.9%). Dosis superiores a 125 mg L-1 NPs-ZnO disminuyen el contenido de clorofila, causando efectos fitotóxicos en las plántulas de L. sativa. En cuanto al contenido de carotenoides el mejor tratamiento fue de 100 mg L-1 NPs-ZnO. El uso de NPs-ZnO sintetizadas a través de un método de precipitación química es una buena alternativa para ser utilizadas como inductores en la biosíntesis de compuestos bioactivos en plántulas de lechuga.
