Published: March 2023

Numerous agricultural wastes are well-defined as low-cost sources and rich in silica content. The residue of oil palm wastes combustion seems a promising silica source and can be recovered through a straightforward method. In this study, the combustion followed by an alkaline extraction method was employed to extract high purity of silica. The oven-dried oil palm decanter cake (DOPDC) was heated at combustion temperatures of 600, 700, 800, and 900°C to produce OPDC ashes (OPDCA), followed by an alkaline extraction using 5M of NaOH solution. Thermogravimetric analysis (TGA) was used to observe the thermal behavior of DOPDC where the suitable combustion temperatures to produce silica ranged between 600 and 1000 ℃. X-Ray Fluorescence (XRF) analysis showed that silica contents were 31-36% after combustion, increasing to 76.95% after the chemical treatment. Moreover, the spherical shape of the silica was observed through electron microscope analysis. It was represented by the aggregation of silica after going through chemical treatment. The X-Ray Diffraction analysis also proved that the amorphous silica was produced, characterized by the hump-shaped spectrum. The infrared analysis confirmed that the silica had been successfully extracted from OPDCA by the presence of silica functional groups shown in the spectrum.

The reduced graphene oxide (rGO) and metal (Cu,Zn)-oxide composites were prepared using a one-step hydrothermal technique. The role of (Cu,Zn)-oxide on the physical and electrochemical properties of the composite was investigated. The composite consists of various shapes of ZnO nanoflowers and micro-spheres, as well as Cu-oxide nanoflakes and octahedron-like shapes. The (Cu,Zn)-oxides were formed in between the rGO layers and observed in the rGO-ZnO, rGO-CuO, and rGO-CuO-ZnO composites. The presence of ZnO, CuO, and rGO within the composite structure is also confirmed by the analyses of crystal structure, microstructure, and surface functional groups. Some excess impurities remaining from the surfactant give considerable differences in the electrochemical performance of the composites. The specific capacitance values of the rGO, rGO-ZnO, rGO-CuO, rGO-(0.5CuO-0.5ZnO), and rGO-(0.25CuO-0.75ZnO) composites are 9.32, 58.53, 54.14, 25.21, and 69.27 F/g, respectively. The formation ofa double metal-oxide structure as well as their insertion into the rGO sheet can significantly improve the electrochemical properties of the supercapacitor.
A poetic inquiry into an EFL learner’s identity and study abroad experience in a non-English speaking country
Authors: Amalina Nur , Musthafa Bachrudin
Published: March 2023

This qualitative case study investigates the way an EFL student reflects on her identity and study abroad experience through a series of pantuns, a four-lined rhyming Indonesian poem. This study conducts a poetic identity analysis on ten English pantuns written by a Ukrainian student who studied English education in Indonesia. The poems were analyzed in terms of their context, content, and stylistic choices. The study unveils that through the ten pantuns, the participant voiced the sociocultural and racial issues she faced as an international student in a non-English speaking country, contemplating her membership in local and global communities, expressing the sense of camaraderie she felt with Indonesian EFL learners and with multicultural community, and constructing new identity in the third space. Further, she recounted her pantun writing experience as challenging due to the genre’s economic word count and rhyming scheme, but satisfying because writing pantun brings her closer to a form of Indonesian literature, and its culture by extension. In pantun’s prefatory section, the participant set the tone of the poem and drew metaphors of her personal and emotional insight, whereas in the following content section, she wrote rhyming lines while expressing said insights. Thus, this study illustrates how writing pantun helps a language learner exercise her linguistic and literary awareness while also enable her to explore her memories, emotion and perception. Pedagogical implication is also presented in this study.

Teacher Professional Development in Developing English Assessments Through TPACK
Authors: Zuhri Fauris
Published: March 2023

Exploring teacher professional development requires two main teaching factors in the digital era. They are internal factors and external. In internal, the teacher plays an essential role in developing professionalism in teaching. In shallow, it is teaching instruments – lesson plans. The appropriate English teacher and lesson plan development contribute significantly to teaching achievement. Therefore, this study explores how English teachers implement technological pedagogical and content knowledge to improve their English instructional assessments in teacher professional development. Implementing technical pedagogical and content knowledge in teacher professional development can gradually enhance their English instructional evaluations. They have different language competencies backgrounds by progressively implementing technological pedagogical and content knowledge in teacher professional development. Still, they can improve their English instructional assessments. The study uses a survey: a questionnaire, interviews, and observation are applied to find the data. The subjects are English teachers who joined teacher professional development in Surabaya 2020. The research results showed that implementing technological pedagogical and content knowledge can improve English instructional assessments in teacher professional development. Three factors contribute to integrating English instructional assessment with technical pedagogical and content knowledge. English teachers are more comfortable making English instructional assessments, alternative instructional English evaluations are available, and improved English instructional reviews. Therefore, English instructional evaluations are more exciting and challenging. Thus, integrating English instructional assessments with technological pedagogical and content knowledge in teacher professional development is crucial in improving teaching English in Indonesia.
Exploring the Local Language Students’ Foreign Language Anxiety in EFL Online Class: Students’ Genders and Speaking Performance
Authors: Hakim Lukman
Published: March 2023

Students’ anxiety, speaking performance and their relation to genders have been investigated extensively in the EFL context and most participants are English students, but most of the studies with the same variables were conducted in an offline setting. Thus, the purpose of this research is to describe the anxiety levels of students who studied another language than English in learning English and to investigate the relationship between their anxiety and performance in English-speaking classes. By employing a quantitative approach, 32 male and 66 female Sundanese Language and Culture Study Program students whose anxiety levels were assessed using Horwitz et al.’s (1986) Foreign Language Classroom Anxiety Scale (FLCAS) participated voluntarily in the research. Because the data were normally distributed and homogenous, the obtained data were analyzed using parametric statistical tools; independent t-test and Pearson Product Moment Correlation. The results imply that the majority of the participants’ anxiety levels were moderate, and there was no statistical difference in students’ anxiety levels between male and female students. Further exploration of the relationship between the anxiety levels of the students and their speaking performance was weak and negative (r = -0.12, p .68). Thus, the online and offline foreign language classroom settings do not seem to differentiate students’ anxiety levels for both male and female students.

Teaching Narrative Texts in Young Learners’ Classroom During Pandemic Covid-19: An Analysis from A Multiliteracies Perspective
Authors: Atsani Iffianti Azka , Damayanti Ika Lestari
Published: March 2023

There is an urgency in education to situate literacy instruction in practices that are responsive to the globalized, multilingual world we live in. The New London Group (1996) has predicted the situation and conceptualized multiliteracies, which view literacy as supplemental, continual, and modifying established literacy teaching and learning rather than replacing traditional teaching and learning practices (Rowsell, Kosnik, Beck, 2008). With the pandemic Covid-19 outbreaks, all schools were forced to be online, encompassing the principles of more than just a traditional literacy pedagogy. Thus, this study aims to see types of teaching and learning resources and pedagogical acts conducted in the classroom seen from multiliteracies perspective during the online classroom. This qualitative study explored the teaching and learning resources and the pedagogical acts based on the multiliteracy pedagogy perspective. The data was collected from classroom observation, interview with the teacher and document analysis. The results showed that the teacher in this study mostly focused on Situated Practice and Overt Instruction in teaching narrative texts in an online classroom. This indicated that the teaching and learning practices only focused on the knowledge process of experiencing and conceptualising. The teacher did not really promote the process of analysing-both functionally and critically- and applying creatively. Keywords: Multiliteracies, Narrative texts, COVID-19, English for Young learners

Authors: Lagos-Hernández Roberto Ivan , Bruneau-Chávez José
Published: March 2023

Introduction: The Mapuche is the most represented ethnic group (79.84%) among the eight native peoples of the Chilean indigenous population, however research examining body composition of aboriginal groups is scarce, including the Mapuche.
Objective: To determine anthropometric and body fractionation differences between indigenous (Mapuche) and non-indigenous students in Chile.
Methods: The sample included 151 indigenous students and 217 non-indigenous male students. Body fractionation was estimated using the protocol described by the International Society for the advancement of Kinanthropometry (ISAK). One-way analysis of variance (ANOVA) was used to estimate the statistical significance of differences between variables.
Results: Mapuche children showed lower values for body weight (p < 0.01), height (p < 0.01) and all skinfolds, body perimeters and bone diameters evaluated compared to non-Mapuche, except for forearm circumference (p < 0.05) and transverse chest diameter (p < 0.05). Regarding body composition, the native students presented lower values of fat mass (p < 0.001), residual mass (p < 0.05) and epithelial mass (p < 0.05). However, they reach higher percentages for muscle mass (p < 0.01) and bone mass (p < 0.05) than non-indigenous students.
Conclusions: Mapuche students present better scores for muscle and bone mass, while showing lower percentages of residual fat and epithelial mass with respect to non-Mapuche students from the same area of residence.

Published: March 2023

Natural-based skin-lightening cosmeceutical products are attracting high popularity nowadays due to their relatively high bioavailability upon application. Artocarpus species have been highlighted with such potential, and our previous studies have reported that Artocarpus heterophyllusLam. stem bark extract exhibited a potent anti-melanogenic activity by reducing melanin content and inhibiting cellular tyrosinase activity in B16F10 melanoma cells. Hence, this study aimed to identify the bioactive fraction from A. heterophyllus Lam. stem bark and determine its anti-melanogenic mechanisms in B16F10 melanoma cells. Our results showed that a fraction (H-3) demonstrated the most pronounced anti-melanogenic effect at 12.00 µg/mL by reducing melanin content to 22.86 ± 2.90% and inhibiting cellular tyrosinase activity at treatment concentration 33-fold lower than kojic acid, without being cytotoxic against B16F10 melanoma cells. Moreover, treatment with H-3 for 24 and 48 h substantially scavenged intracellular reactive oxygen species (ROS) of hydrogen peroxide-challenged B16F10 melanoma cells by 1.8 and 4.4%, respectively. Based on the microarray profiling and qPCR analysis, H-3 downregulated Creb3l1, Creb3l2, Creb3l3, Mitf, Tyr, Tyrp1, and Dct genes in B16F10 melanoma cells, whereas the expression of Map3k20, Mapk14 (p38), and Foxo3 genes was markedly increased. Altogether, these results demonstrated that H-3 exhibited its anti-melanogenic activity in B16F10 melanoma cells through scavenging ROS and concurrent inhibition of the cAMP and activation of the p38/MAPK signaling pathways. These findings indicate that H-3 has the potential to be used as a skin lightening cosmeceutical agent in the treatment of skin hyperpigmentation.

SPECIFICS OF DEVELOPMENT OF AESTHETICS STUDIES: BETWEEN SOVIET AND CHINESE MARXISM
Authors:   Taras Shevchenko National University of Kyiv, Ukraine, Turenko Vitalii
Published: March 2023

The article reveals the features of the formation and functioning of aesthetic research in such two areas of Marxism as Soviet and Chinese. The study identified three key stages in the development of aesthetics in Soviet Marxism – the pre-war (the 1920s and 1930s), late Stalinism and the Khrushchev thaw, and the late period (1970-1980s). It should be noted that in the context of Soviet Marxism, the key tasks were that aesthetics becomes influential and in-demand science, included in the program of "technical progress" and "education of the builder of communism", important ideological, aesthetic, and applied field of philosophy. Therefore, in addition to the fact that purely ideological works were developed within the framework of aesthetic discourse, aesthetics itself in Soviet Marxism was able to develop thanks to contacts with semiotics, psychology, anthropology, cultural history, and sociology. Relying on a selective stream of translations of Western philosophies of art, Soviet aesthetics is beginning to resonate with global trends, which is facilitated by the unspoken consensus of the idea of aesthetics as a part of philosophical and humanitarian knowledge that has its own autonomy. Proved that in China culture and the cultural revolution are inextricably linked with the Marxist projects of critiquing capitalist modernity and building alternative modernity. Aesthetics and culture also were at the center of attention in Chinese Marxist circles. In this respect, the diverse practices and designs of Chinese Marxism are similar to those of Western Marxism or an equally distinct variety of Euro-American Marxist intellectual enterprises. Aesthetic Marxism in China had a dual mission – to criticize the internal contradictions of revolutionary hegemony and to offer a constructive vision of culture in a post-revolutionary society. This is the value of Chinese aesthetic Marxism, the implications of which go beyond China proper in the world of global cultural criticism. Moreover, being non-Western, Chinese aesthetic Marxism deliberately questioned the inherent Eurocentrism of Marxism. If this Eurocentrism is to be challenged and problematized, the questions posed by Chinese aesthetic Marxists cannot be ignored.

INTERPRETATION OF "PRATYAKṢA" IN THE FIRST CHAPTER OF THE FIRST PART OF "NYĀYA SŪTRAS"
Authors:   Taras Shevchenko National University of Kyiv, Ukraine, Hnatovska Нanna
Published: March 2023

The Article is concerned with the investigation of interpretation of the concept "pratyakṣa" in the first chapter of the first part of "Nyāya Sūtras", which became the determining ground for the entire subsequent history of the development of this concept in the teachings of the adherents of this philosophical school and their polemics with opponents. The methods of etymological and contextual analysis are applied, the key meaningful connotations of "pratyakṣa" are outlined, and the main issues of its interpretation and translation are revealed. The first chapter of the first part of "Nyāya Sūtras" is the systemic core of the work as a whole, therefore its thorough study is of primary importance, both for the reconstruction of the teachings of Nyāya darshan, and for clarifying the specifics of the actualization of the lexemes presented in this part of the text and in the philosophical discourse of India as a whole. However, the brevity of the text chosen for analysis in this article opens a rather comprehensive perspective of different interpretations and creates a number of open questions. The duration of the tradition of comments dedicated to "Nyāya Sūtras" is an evidence of the importance of this work and the difficulty of reconstructing its content. The open questions actualized in the process of this study should not only become the basis for further investigations, but also reveal the specifics of the problematization of "pratyakṣa" in the philosophical discourse of India. The article reveals that the study of the concept of "pratyakṣa" in the teaching of Nyaya darshan, first of all, requires the analysis of the following concepts: prama̅ṇa, indriya, manas, artha, jñāna, buddhi. The article also suggests that "pramana pratyakṣa" is rather a "situation" of acquiring knowledge that meets the criteria of truth, rather than a simple "tool of knowledge" or "ability to know", so its simple translation as "perception" seems insufficiently substantiated. The article declares that the issue whether every contact between indriya and artha necessarily leads to the formation of a jñāna that meets the criteria of avyapadeśyam ("that which precedes definition and expression"), avyatirekavyabhicārin ("that which is clear, distinct, uncontroversial and steady'), vyavasāyātmaka ('that which is intense, bright and full of energy') is open and urgent for further research. It also states that the issues whether it is possible to talk about the contact of indriya, in the sense of a simple list of empirical senses (sight, hearing, touch, taste, smell), with artha without the mediation of manas; and how to interpret the possible role of the Western concept of "consciousness" in this process are also important.
LANGUAGE "LOCKDOWN" AS A MEAN OF TOTALITARIAN MANIPULATIONS

Published: March 2023

This article explores the role of language and ideology in Soviet philosophy and education. The author argues that the Soviet regime deliberately used philosophy as a tool for manipulation, with the aim of creating a common understanding that Marxism and Leninism are the only true doctrines of philosophy. The course of philosophy was mandatory at all levels of education and was fully standardized, with a focus on scientific grounds that only Marxist philosophy was valid. The article also highlights the role of language in the Soviet language lockdown policy, where the Russian language was prioritized as the primary language of education and science, suppressing national languages and cultures of member countries. Furthermore, translations of key philosophical texts were selectively done, presenting only those texts that did not touch upon political or religious issues. The article concludes that the oppressive language and ideology practices in Soviet philosophy had a significant impact on the intellectual and cultural development of the Soviet Union and its member countries.
Giant condyloma acuminatum in a female renal transplant recipient with rapid development: a case report
Authors: EVRÜKE İpek Merve , USTA KORKUT İrem
Published: March 2023

Giant condyloma acuminatum (GCA) usually occurs on a set of human papillomavirus (HPV) subtype 6 or 11 infections and is characterized by cauliflower-like aggressive growing mass over the anogenital region. Lesions are more often observed in immunocompromised patients since host immunity is one of the main risk factors of the disease. We report a case of a GCA in a sexually inactive renal transplant recipient. A 25-year-old patient who had renal transplantation four years prior and has been receiving immunosuppression therapy since presented with the rapid growth of a vulvar mass noticed. A wide surgical excision was performed and the patient had no recurrence at her follow-ups. Surgical excision is the definitive treatment in immunocompromised patients with the rapid growth of vulvar condylomas.

Purpose: The aim of this study is to show whether radiologically diffusion tractography imaging (DTI) and electrophysiologically F responses methods support clinical examination in Amyotrophic Lateral Sclerosis (ALS). It is to determine the relationships between these two methods.

Materials and Methods: Patients with a definite diagnosis of ALS according to the Revised-El Escorial and Awaji criteria at any stage of the disease, who applied to the Electromyography (EMG) laboratory of the Neurology Clinic of Istanbul University Cerrahpaşa, Cerrahpaşa Medical Faculty, prospectively and cross-sectionally, were included in the study. The revised ALS functional rating scale (ALSFRS-R) was scored. Electrophysiological studies included routine nerve conduction studies, F responses and needle EMG. In radiological examinations, diffusion tractography imaging (DTI) maps were obtained in brain and cervical Magnetic Resonance Imaging (MRI) and diffusivity and fractional anisotropy (FA) values were compared.

Results: The mean age of the 12 volunteer patients included in the study was 55.92±9.68 (43-72), and consisted of 4 female and 8 male individuals. The mean ALSFRS-R score was 35.75±7.86 (24-46). MRI was performed in 11 of the patients, spinal imaging could not be performed in one patient. The mean age of the 11 patients who were imaging was 56.4±9.8 years and the disease duration was 2.7±1.9 years. Low values of DTI-FA were found to be associated with poor respiratory and speech scores as assessed by linear regression analysis. Repeater F responses in the ulnar nerves were also associated with a high ALSFRS-R score.

Conclusion: In our study, we observed that low values of DTI-FA were associated with poor respiratory and speech scores. Showing the correlation of low FA with a vital function such as respiration may indicate that this technique will be helpful in the prognosis and progression of the disease. The increase of repeater F responses in the ulnar nerves in those with high ALSFRS-R scores suggests that it is worth investigating whether ALS can be used in differentiating from other anterior horn diseases. The results of this study suggest that DTI-FA, which is an advanced radiological evaluation, and repeater F responses as an electrophysiological method may support early diagnosis in ALS.
P/SVAmplitude Ratios of Shallow Isotropic Explosions and Earthquakes Could Be Indistinguishable at Local Distances: Insights from Single-Station Waveform Simulations
Authors: Zhang Miao
Published: March 2023

Shear waves play a key role in seismic discrimination between explosions and earthquakes due to their different source mechanisms. However, shear waves are often observed in field explosions with unexpectedly large amplitude, and their generation mechanism is still a significant unresolved question in seismology. Many explanations have been proposed, including the asymmetry of explosive sources, and heterogeneity and/or anisotropy of the Earth’s subsurface. However, it has not been well understood whether source or velocity structure can independently and sufficiently explain the shear waves generated by explosions. Theoretically, tangential SH waves can be converted and scattered from vertical and radial SV waves due to anisotropy and heterogeneity. Thus, it is essential to understand the generation of SV waves by explosions. In this study, we utilize the frequency–wavenumber algorithm and 1D layered velocity models to simulate waveforms of isotropic explosions and double-couple earthquakes at local distances (<20 km). Our results suggest that explosions and earthquakes may generate comparable SV waves if both occurred within a near-surface velocity gradient zone. The earliest SV waves by explosions appear to originate from the near-source region. It implies that P/SV amplitude ratios of explosions and earthquakes could be indistinguishable under certain circumstances.
Production of Mandarin Chinese Tones by Sri Lankan CFL Learners: An Acoustic Analysis
Authors: Dassanayake Noel
Published: March 2023

Tonal variation in Mandarin forms a relationship with the meanings of words at a lexical level. Tones and tone sandhi are considered distinctive features of Mandarin Chinese phonetics; thus, acquiring accurate Mandarin pronunciation is challenging for speakers of other languages. The present study examined the production of Mandarin tones by Sri Lankan learners through acoustic analysis of f0 using Praat. The study participants were seven (n=7) undergraduate students at intermediate-level Chinese. Each participant recorded a sample of 20 elements, totaling 140 at three tiers: isolation, disyllabic form, and synthesis. The recorded acoustic data were analyzed using Praat 5.4.04 and SPSS Statistics 21. The results indicated that the mean f0 values of the realization of the four tones by the informants are heterogenous at all three tiers. The realization of T3 demonstrated a low accuracy, while T2 was realized with the highest accuracy at all three tiers. As revealed by the tone sandhi analysis, participants have resorted to the underlying representation of the tone sandhi than the surface realization.
