GENDER DIFFERENCES AND LANGUAGE LEARNING STRATEGIES OF INDONESIAN STUDENTS: A CRITICAL RESEARCH REVIEW
Authors: Martina Martina , Afifi Nur
Published: January 2025

This study explores gender differences in language learning strategies (LLS) within the Indonesian context. Drawing on various studies, it reveals mixed results regarding the preference for strategies between male and female students. Some studies, such as Budiarti (2022), report no significant gender differences, while others (e.g., Rianto, 2020; Melvina et al., 2020) suggest that female students, particularly those with higher English proficiency, use strategies more frequently. Female learners tend to prefer metacognitive strategies (e.g., planning and self-monitoring), while male students lean toward cognitive strategies (e.g., memorization) and social strategies (e.g., peer interaction). The study highlights strengths in the use of validated instruments like the Strategy Inventory for Language Learning (SILL) but also identifies weaknesses such as response bias and limited consideration of contextual factors like motivation and social support. These findings indicate that gender influences strategy use, but external factors, including proficiency and motivation, also play significant roles. The research recommends adopting more comprehensive research methods and practical teaching approaches that account for gender-specific strategy preferences, thus fostering more inclusive language learning environments. This study contributes to both theoretical and practical insights in foreign language education in Indonesia.

Published: January 2025

The purposes of this research are to 1) find out the influencing factors of the students' unwillingness to speak in EFL classroom. and 2) find out how the factors influence students' unwillingness to speak in EFL classroom. A mixed-methods approach was used. The research subjects were 10th grade students majoring in Agribusiness Processing of Agricultural Products at SMK Negeri 4 Jeneponto. Participants were selected through a purposive sampling technique in determining the sample of this research, nine students were selected as participants, with three students categorized as having low score in English practice, three students categorized as having intermediate score in English practice, and three students categorized as having high score in English practice. The results of the research showed that psychological factor influencing students' unwillingness to speak in EFL classroom is lack of self-confidence. Meanwhile, linguistic factors included: (1) Lack of vocabulary (2) Lack of grammatical pattern knowledge and (3) Incorrect Pronunciation. A lack of confidence, frequently rooted in past negative experiences of language errors that have resulted in reluctance to speak in public, is a significant psychological barrier, discouraging students from participating. Linguistic challenges further exacerbate this issue; limited vocabulary and insufficient knowledge of grammatical patterns lead to hesitation and fragmented speech, as students struggle to articulate their thoughts clearly. Pronunciation errors also play a crucial role, as they can affect intelligibility and cause students to fear that their speech may not be understood, thus reinforcing their unwillingness to speak up in class.

Authors: Nur Arsyad Susalti , Tangkin Wiyun Philipus , Sumartono Sumartono , Astuti Budi
Published: January 2025

Jerome Bruner's cognitive theory plays a significant role in modern education, particularly in primary education, by emphasizing active student involvement in the learning process. This theory is structured around three stages of learning: enactive, iconic, and symbolic. Bruner's discovery learning approach encourages students to construct knowledge through exploration, fostering critical thinking, creativity, and problem-solving. The spiral curriculum further supports continuous learning, revisiting basic concepts at progressively complex levels. In the context of 21st-century education, Bruner's theory aligns well with the development of higher-order thinking skills, communication, and collaboration, supported by the integration of technology. Despite the promising outcomes, challenges such as limited resources, teacher training, and technology integration remain. This literature review explores studies from 2010 to 2024 that analyze the application of Bruner's cognitive theory in primary education, with a focus on the effectiveness of discovery learning, scaffolding, and spiral curriculum in fostering critical thinking and 21st-century skills

Práxis dialógica, pesquisa como princípio formativo e a formação das novas gerações em Benincá
Authors: Fávero Altair Alberto , Cenci Angelo Vitório
Published: January 2025

The present text aims to focus on a potential relation among dialogical praxis, research as a formative principle and formation of new generations. In order to do this, we begin by resuming the dialogical praxis in educational and philosophical hermeneutic tradition indicating the formative dimensions contained in it. In this regard, Gadamer’s contributions (1999; 2002) stand out, as well as their implications for the educational field carried out by authors such as Hermann (2002) and Cruz (2010), among others. In the following step, always considering the hermeneutic role of dialogical praxis, we go into Benincá’s work to explore the way how he takes common sense as the basis of praxis methodology research. This step allows us to advance by thematizing the existing articulation among the praxis method, the researcher’s continuing education and the research group’s formative role. In conclusion, we demonstrate the contribution which this approach brings to the formation of new generations.
SYNTHESIS AND APPLICATION OF PMMA EMULSION FOR COATING MEDICAL NATURAL LATEX GLOVES
Authors: Zhang Chengye , Yuan Yizhong , Sun Jinyu , Zhang Yao , Tian Xiaohui , Cai Chunhua
Published: January 2025

Natural latex gloves are prone to allergies and adhesion during use. Corn starch and talc, while improving adhesion, do not solve the allergy problem. These powders even increase allergy transmission pathways as well as create safety hazards such as granulomas. Depositing polymethylmethacrylate (PMMA)-chitosan (CS) on glove surfaces improves surface adhesion and does not become airborne like powders. However, the physical stability of the film formed by PMMA-CS deposition leaves much to be desired, and azobisisobutyronitrile (AIBN) and hexadecane present safety hazards. To ameliorate these problems, PMMA-CS was prepared by replacing AIBN and hexadecane with tween-80 and β-cyclodextrin, and PMMA-TOFA was prepared by using methyl methacrylate (MMA) and tall oil fatty acid (TOFA). The sulfur-prevulcanized natural rubber (SPNR) films deposited with PMMA-CS and PMMA-TOFA (PMMA CS/PMMA-TOFA/SPNR) had fewer safety hazards, higher roughness and physical stability. It is expected that PMMA emulsion can be applied to the inner and outer surfaces of medical gloves to reduce the safety hazards that exist in medical gloves.
IMPACT OF 1-BUTYLPYRIDINIUM BROMIDE–MODIFIED GRAPHENE NANOPLATELETS ON THE PROPERTIES OF SBR NANOCOMPOSITES
Authors: Joseph Subin , Francis Bejoy
Published: January 2025

It is essential to achieve a strong interfacial interaction between the filler and polymer matrix for the production of polymer nanocomposites with superior performance. Ionic liquid (IL) 1-butylpyridinium bromide (BPB) was used for the surface modification of graphene nanoplatelets (GnPs). The modified GnP (PMG) was characterized using Fourier transformation infrared spectroscopy, Raman spectroscopy, X-ray diffraction, X-ray photoelectron spectroscopy, transmission electron microscopy (TEM), and thermogravimetric analysis. BPB functioned as an intermediary between GnP and SBR via noncovalent interactions and promoted GnP dispersion in the SBR matrix. TEMs demonstrated that IL facilitates the homogeneous dispersion of PMG in the SBR/PMG nanocomposites. Dynamic mechanical analysis was used to understand viscoelastic behavior of the nanocomposites. The fraction of immobilized rubber chain around the PMG in the nanocomposites was obtained from the differential scanning calorimetric curve. The SBR nanocomposite prepared shows an improvement of 273% in tensile strength and 12.1 °C in degradation temperature.
CONTRIBUTION OF CROSSLINK NETWORK STRUCTURE TO THE VISCOELASTIC CHARACTERISTICS OF EPDM: TUNING DYNAMIC PROPERTIES THROUGH HYBRID CURING
Authors: Parathodika Arshad Rahman , Aziz Barkat , Naskar Kinsuk
Published: January 2025

EPDM is the fourth most widely used general-purpose elastomer, accounting for approximately 10% of total synthetic rubber production. With its broad applications in the automotive and construction industries, the analysis of EPDM’s dynamic viscoelastic properties is critical for optimizing product performance. Although the effects of various fillers and their structures on EPDM’s viscoelastic behavior have been widely studied, the impact of crosslink network architecture on long-term viscoelastic properties is seldom explored. To investigate the influence of different crosslink types and their compositions on the long-term viscoelastic behavior of EPDM, we have used thiol-amine analysis, time–temperature superposition for frequency-dependent properties, and temperature scanning stress relaxation. We establish correlations between crosslink features and the viscoelastic properties of carbon black–filled EPDM. In addition, we explore the effects of unique crosslink networks formed through hybrid cure systems containing accelerated sulfur and peroxide on the viscoelastic performance of EPDM. Our findings indicate that the frequency dependence of viscoelastic properties is governed by crosslink length, whereas temperature dependence is influenced by crosslink type. The results also indicated a strong correlation between plateau modulus and polysulfide crosslinks. These insights offer valuable guidance for optimizing the viscoelastic characteristics of next-generation elastomeric materials.

A Data Driven Machine Learning Approach for Predictive Analytics in Healthcare Domain
Authors: Deepa Nikam
Published: January 2025

Machine Learning and Deep Learning are transforming the healthcare domain so as to aid medical practitioners with effective analytical tools which can find pattern in copious amounts of data and augment the diagnosis and potential health risks. While the use of statistical techniques may be shrouded with skepticism for the healthcare sector, its inevitability came into light recently with the Covid-19 pandemic wherein the number of cases saw an exponential growth stressing the healthcare infrastructure. The sudden outbreak of such a global medical emergency stressed upon the need to develop intelligent computational models which can analyze medical datasets and render results pertaining to the onset or existence of a disease, potential cases and hotspots in the future. Such systems would offload the existing medical infrastructure and also give medical practitioners valuable inputs as a strong second opinion. Such systems would also render primary screening in remote location where necessary medical facilities are unavailable. Additionally, controlling and arresting potential pandemic like situations, by identifying potential hotspots or estimating future number of cases would also allow government agencies. This paper presets a data driven approach for classifying medical images, as well as a regression model for forecasting future cases. A comparative analysis with benchmark models in the domain of research clearly indicates that the proposed model outperform exiting research in terms of classification and forecasting accuracy

Published: January 2025

Neurodegenerative diseases are the consequence of progressive brain degeneration caused by the death of nerve cells. Many factors that influence the neurodegeneration development are still not fully known. A lot of studies indicate the contribution of metal ions in this process. Copper, zinc, and iron are trace elements essential for proper functioning of the body. They are part of many enzymes participating in the transmission of the nerve signals, electrons transport, neurotransmitters and nucleic acids synthesis, and oxygen storage. Disorder of metals homeostasis leads to the development of severe diseases and nervous system degenerations. An excess of copper and iron ions causes a significant increase in cellular oxidative stress. Metals catalyze the reactions of free radicals formation that destroy proteins, lipids, and nucleic acids. High concentration of copper and iron ions were found in the deposits of amyloidogenic proteins. Amyloid β (Alzheimer disease) and α synuclein (Parkinson disease) have ions binding chain structures. The metal-protein interaction increases oligomerization speed in vitro. A lot of evidence suggests that the disorder of Cu, Zn and Fe homeostasis accelerates the progress of brain neurodegeneration. Human organism contains many metals, which are not needed for the proper functioning of the body, e.g. aluminum. Al binds to nucleic acids causing an increase in cellular oxidative stress and initiating proteins oligomerization. The presence of aluminum is also considered to be disadvantageous for the nervous system. The lack of medicines for neurodegenerative diseases forces us to search for new therapies. The development of degenerations could be slowed down by chelators of toxic metals, but first, these diseases must be better understood. Adverse effects of high concentration of metal ions on brain functioning are not fully known. This knowledge is necessary to find effective drugs.

Solid phase extraction (SPE) is an analytical procedure developed with the purpose of separating a target analyte from a complex sample matrix prior to quantitative or qualitative determination. The purpose of such treatment is twofold: elimination of matrix constituents that could interfere with the detection process or even damage analytical equipment as well as enriching the analyte in the sample so that it is readily available for detection. Dispersive solid phase extraction (dSPE) is a relatively recent development of the standard SPE technique that is attracting growing attention due to its remarkable simplicity, short extraction time and low requirement for solvent expenditure, accompanied by high effectiveness and wide applicability. There is an enormous abundance of articles concerning advances in sample preparation and analysis published every year. The aim of this review is to bring to closer attention developments of materials with potential application as sorbents in dSPE technique through a thorough survey of recently conducted analytical studies focusing on methods utilizing novel, interesting nanomaterials in dSPE procedures and evaluation of their performance and suitability based on comparison of provided validation parameters with previously reported analytical procedures. The first part of this review focuses on widely known and utilized materials such as silica and carbon and their modifications, up to and including graphene and carbon nanotubes. Studies chosen for this review will be listed in tables alongside their relevant validation parameters at the end of each chapter. Applications found to be particularly interesting due to high effectiveness, unusual operating procedure or scope, among other reasons, will be described in greater detail.

This work is focused on the electroanalytical application of the system composed from two immiscible electrolyte solutions also known as the electrified liquid-liquid interface. The particular attention is given to the electroanalytical signals originating from the simple ion transfer reactions (transfer of ion either from the aqueous to the organic or from the organic to the aqueous phase) providing ionic currents that can be probed in a function of the applied potential. Advantages and limitations of the soft junctions are underlines and discussed based on the examples published in the literature. Finally, future directions are given further indicating the utility of the concerned platform for the electroanalytical applications.

Rising prices of electricity, conventional fuels and heating require decisive steps in the further development of technologies based on renewable energy sources. These include geothermal-; hydrothermal-; aerothermal-; and solar energy. Due to the fact that the petrochemical industry is one of the fastest growing branches of the economy, we would like to expand on the topic related to biofuels. Biodiesel is an alternative fuel similar to conventional diesel. It is usually made from animal fat, vegetable oil and waste cooking oil. Its biodegradability, non- toxicity and lack of sulfur and aroma content make it superior to conventional gasoline and diesel. During fuel consumption, it emits fewer air pollutants and greenhouse gases other than nitrogen oxides. In this literature review, we will discuss the latest trends in the world related to catalysts used in biodiesel synthesis.

Plastics are currently used in almost every branch of industry. Their popularity is due to excellent mechanical properties, durability combined with low weight. Global production of plastics in 2020 reached 387 million tons and a great amount of waste from plastics is generated as they are usually non-biodegradable and often are used only once before disposal. Since the 1970s, the problem of plastics pollution started to be noticed, and then the first regulations on their production, limiting and management options were introduced. There are several methods preventing the plastics waste going to landfill. Among the plastics management methods are mechanical recycling, solvent based purification, chemical recycling, energy recovery and biodegradation (Figure 1). Mechanical recycling is the reprocessing of the plastic waste to its original form (polymer) using simple physical operations like grinding, separating, extruding. This option is the most popular for thermoplastics as they are easily reprocessed and the cost operations are low. During solvent based purification the plastics products are purified from different additional compounds like colorants, antioxidants, fillers to obtain original polymer. Biodegradation is available only for some polymers. Energy recovery process releases the energy contained within plastics through combustion and is suitable only for materials which are difficult to recycle. Nowadays chemical recycling of plastic waste is the most noteworthy polymers recovery technique as it is complementary to mechanical recycling. Chemical recycling can be divided into two main processes: chemical and thermal depolymerization (Figure 2). Thermal depolymerization processes are conducted using heat and in the absence of oxygen, or with limited access to oxygen or other compounds (H2, CO2). It converts plastics into monomers or basic chemical (hydrocarbons, oil, H2) and is typically used for polyolefins, PMMA, PS. During chemical depolymerization plastics are broken down into oligomers or monomers as a result of a chemical reaction with a low molecular weight agent (H2O, alcohols, amines, glycols, acids) and usually refers to condensation and addition polymers (PET, PC, PA, PU). Chemical recycling enables for multiple recycling of plastics to its monomers, which can be polymerized to produce the original polymer. The manuscript presents a literature review on chemical recycling of commonly used plastics such as vinyl polymers, polycondensation polymers, thermosets and polymer blends.
