Published: February 2024

Salah satu tipe rumah tradisional di Sumatera Selatan adalah Rumah Ulu banyak ditemui di dataran tinggi dan pegunungan di Kab. Muara Enim  khususnya Desa Pulau Panggung, Kec. Semende Darat Laut,. Rumah ini memiliki karakter rumah tradisional berupa rumah panggung (bangunan rumah kayu yang ditopang oleh beberapa tiang kayu atau batang pohon secara utuh). Saat ini, Rumah Ulu/Semendo telah mengalami banyak perubahan dari sisi arsitektur, yakni perubahan material dan perubahan fungsi ruangan. Hal yang paling mencolok adalah banyaknya kolong rumah Ulu/Semendo telah berubah fungsi menjadi ruang tamu, garasi ataupun sebagai tempat berjualan. Perubahan-perubahan ini terjadi dengan sangat signifikan sehingga pada masa sekarang, Rumah Ulu asli sudah sangat sulit untuk ditemukan utuh. Tujuan dari penelitian ini adalah mengetahui perubahan material dan fungsi ruang pada rumah Ulu/Semendo di Kecamatan Semende Darat Laut. Metode yang digunakan adalah metode kualitatif. Metode pengambilan data dilakukan dengan cara in-depth interview, dokumentasi, dan observasi lapangan. Hasil penelitian yang ditemukan adalah Rumah Ulu/Semendo berangsur-angsur mengalami perubahan dari segi material dan fungsi ruang. Saat ini sangat sulit untuk menemukan Rumah Ulu/Semendo yang masih asli. Perubahan-perubahan ini sangat dipengaruhi sulitnya menemukan bahan material asli sehingga masyarakat harus mensubsitusi dengan bahan material lain. Selain itu, perubahan ini juga terjadi dikarenakan, masyarakat di daerah Semendo memiliki kebutuhan-kebutuhan tambahan akan sarana dan prasarana seperti dapur, toilet, dan sebagainya. Pada akhirnya, lambat laun, Rumah Ulu/Semendo akan mulai hilang dan tidak dapat ditemukan lagi.
El proceso de verticalización en la CDMX (1990-2017) y la institucionalización de la participación ciudadana. Una lectura desde el fenómeno NIMBY
Authors: Garrido Rodríguez Laura Alejandra , Pérez Campuzano Enrique
Published: February 2024

En los últimos veinte años es más que evidente el proceso de verticalización de la oferta inmobiliaria residencial en la Ciudad de México. A la par de este proceso, existe una creciente preocupación social por los cambios en la ciudad y en los barrios. La transformación de la urbe ha generado diversas reacciones. En este artículo se presenta una lectura de éstas desde un punto poco analizado: la institucionalización de la participación ciudadana. Para ello se usan datos de la transformación de la oferta inmobiliaria en la Ciudad de México de 1990 a 2017 y las denuncias presentadas ante la Procuraduría Ambiental y de Ordenamiento Territorial (PAOT). Los resultados indican que, a la par de la transformación de la oferta inmobiliaria (mayor densidad y en altura), también las denuncias crecen. Este proceso podemos equiparlo al denominado No en mi patio trasero (NIMBY, en inglés).

Published: February 2024

This qualitative study delves into the impacts of taking on the role of a class monitor among Vietnamese English-major students, focusing on the nuanced experiences and growth trajectories stemming from this leadership position. Conducted within two higher education institutions in the Mekong Delta, the research employed semi-structured interviews to capture the voices and narratives of 15 participants. Grounded in the Constructivist Grounded Theory and the Phenomenological Approach, the study unearthed several pivotal themes. These included feelings of empowerment through leadership responsibilities, the intricate balancing act of cultural mediation and dual identities, enhancement of English communication skills, the evolution of prioritization skills, profound introspective journeys towards self-realization, and a deep-seated desire to inspire and create a lasting legacy. The findings not only shed light on the multifaceted impacts of the class monitor role but also underscore the transformative potential of such positions in fostering personal and academic growth. The study contributes uniquely to the discourse on student leadership, offering educators, policymakers, and institutions a deeper understanding of the experiences and challenges faced by student leaders in a Vietnamese context. It emphasizes the importance of recognizing and harnessing the profound personal and collective journeys these roles can initiate.
Comparing Grammar Translation Method and Communicative Language Teaching in EFL Context: A Qualitative Literature Review
Authors: Nisha Paulomi Rahman
Published: February 2024

Teaching English as a foreign language (EFL) differs greatly from teaching English as a first language (L1). To ensure that teaching and learning are successful and efficient, teachers must possess a broad range of pedagogical expertise. Each method needs to be adjusted to the particular educational and environmental setting. The primary objective of this article is to provide comprehensive insights into two prominent language teaching methods, namely the Grammar Translation Method (GTM) and Communicative Language Teaching (CLT). While GTM has been historically prevalent, CLT has recently gained widespread popularity. This paper focuses on the understanding of educational practitioners, particularly in the domain of English Language Teaching (ELT) setting, by conducting a comprehensive comparison of GTM and CLT thoroughly, focusing on teaching techniques, characteristics of both teaching methods, and the way the instructor addresses students’ mistakes. Although CLT is recognized as the more realistic and advantageous method in contemporary contexts, it is still acknowledged that GTM possesses certain positive attributes. Additionally, since every country has its own unique set of circumstances, social norms, and background, the teacher must be aware of the most suitable teaching-learning method.

Pronematus ubiquitus (McGregor) is redescribed based on specimens collected at the type locality. Additionally, in a survey for natural enemies of Aculops lycopersici (Tryon), P. ubiquitus was found in most European countries where samples were gathered as well as in Morocco. Together with specimens available from museum collections and originating from Brazil, South Africa and Türkiye, the newly collected specimens were measured and morphologically compared with those from the type locality. Additionally, single female expansion lines were set-up with specimens from California (USA), Belgium, France, Italy, The Netherlands and Morocco, and molecular analysis were performed in order to construct a phylogenetic tree. The tree showed differences between origins, but this was assigned to intraspecific variation. A PCA analysis on morphological characters separated the Brazilian specimens from those of all other geographical origins. The Californian (USA) specimens grouped together, as did the Moroccan and all European specimens, but with overlap between the groups. The Brazilian specimens were described as a new species, P. brasiliensis n. sp. All other specimens were considered as P. ubiquitus. Furthermore, we searched for types of early described Pronematus species and studied P. rykei, P. karrooi and P. tenuisetosus types; the first two species were confirmed morphologically as a distinct Pronematus species while the latter belongs to the genus Pseudopronematulus. The morphological characteristics of specimens that were used for a recent redescription of P. rykei did not coincide with our redescription of the type. We transferred those specimens to the new species, P. juglandi sp. nov.
Oral bacteria may affect conjunctival microorganisms in brachycephalic dogs: a preliminary study
Authors: Shin Sehan , Seo Kangmoon , Lee Gi Yong , Yang Soo-Jin , Kim Se Eun
Published: February 2024

OBJECTIVE

To evaluate the prevalence of oral bacteria in the conjunctiva of brachycephalic and nonbrachycephalic dogs.

ANIMALS

12 brachycephalic (9.58 ± 3.55 years) and 12 nonbrachycephalic (8.33 ± 4.92 years) dogs without systemic disease, regardless of breed and sex, were included in the study, and half of the dogs in each group had periodontitis.

METHODS

This prospective study investigated clinical data including craniofacial ratio, ophthalmic examination results, and periodontal status of the included dogs. Bacterial samples were collected by swabbing the oral mucosa and conjunctival surfaces. The presence and quantity of bacteria were analyzed by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry, 16S rRNA sequencing analysis, and the 10-fold dilution method. Statistical analyses were performed to assess correlations and factors influencing the presence of oral bacteria in the conjunctiva.

RESULTS

The most common bacteria in the conjunctival flora in both groups were Micrococcus luteus, Corynebacterium spp, and Staphylococcus spp. The prevalence of oral bacteria on the conjunctival surface was 33%, with a significantly higher incidence in brachycephalic dogs (P = .027). Oral bacteria detected in the conjunctiva were predominantly Frederiksenia canicola, Neisseria spp, and Moraxella spp. Multiple regression analysis identified age, craniofacial ratio, and gingival index as factors influencing the presence of oral bacteria in the conjunctival flora.

CLINICAL RELEVANCE

Oral resident bacteria have often been isolated from severe infectious corneal ulcers. This study provided evidence that brachycephalic dogs may require dental prophylaxis to reduce their oral bacterial load and that the association of oral bacteria in ocular diseases should be considered.

Multi-User System for Earth Sensing Spacecraft Attitude Calibration and Analysis
Authors: Whorton Mark S. , Crassidis John L.
Published: February 2024

The Teledyne Multiple User System for Earth Sensing (“MUSES”) was developed for commercial Earth imaging and instrument technology development on the International Space Station (ISS). MUSES simultaneously hosts up to four Earth ensing instruments and provides inertial pointing and tracking to orient instruments toward planned targets on the ground. Up to four instruments are robotically installed on MUSES and periodically interchanged as warranted. MUSES was delivered to the ISS in June 2017, with initial testing successfully completed and subsequently documented in an initial requirements verification report. Assessing the performance of the MUSES attitude estimation system is challenging due to the lack of an independent attitude estimate of the platform attitude. A novel approach is introduced herein where the ISS attitude estimate, derived from ISS Global Positioning System sensors, is employed as an independent measure of MUSES platform attitude. Spectral decomposition methods are used to account for the contributions of ISS deformations to the variance in disparities between the ISS and MUSES attitudes and thus enable a less conservative estimate of the variance in MUSES attitude error. Implementing the spectral decomposition results in a best estimate upper bound on MUSES attitude errors of 34.5 and 27.7 arcsec, respectively, in the along-track and cross-track axes. Both the simulated and real results obtained from the spacecraft are presented.
Investigation of Compressor Cascade Flow Using Physics-Informed Neural Networks with Adaptive Learning Strategy
Authors: Li Zhihui , Montomoli Francesco , Sharma Sanjiv
Published: February 2024

In this study, we utilize the emerging physics-informed neural networks (PINNs) approach for the first time to predict the flowfield of a compressor cascade. Different from conventional training methods, a new adaptive learning strategy that mitigates gradient imbalance through incorporating adaptive weights in conjunction with a dynamically adjusting learning rate is used during the training process to improve the convergence of PINNs. The performance of PINNs is assessed here by solving both the forward and inverse problems. In the forward problem, by encapsulating the physical relations among relevant variables, PINNs demonstrate their effectiveness in accurately forecasting the compressor’s flowfield. PINNs also show obvious advantages over the traditional computational fluid dynamics (CFD) approaches, particularly in scenarios lacking complete boundary conditions, as is often the case in inverse engineering problems. PINNs successfully reconstruct the flowfield of the compressor cascade solely based on partial velocity vectors and near-wall pressure information. Furthermore, PINNs show robust performance in the environment of various levels of aleatory uncertainties stemming from labeled data. This research provides evidence that PINNs can offer turbomachinery designers an additional and promising option alongside the current dominant CFD methods.
NUMERICAL MODELING OF THE STRESS-STRAIN STATE DURING ADDITIVE MIG WELDING WITH CuSi3Mn SILICON BRONZE
Authors:   National Technical University of Ukraine «Igor Sikorsky Kyiv Polytechnic Institute», Prokhorenko Dariа , Lahodzinskyi Ivan ,   National Technical University of Ukraine «Igor Sikorsky Kyiv Polytechnic Institute»
Published: February 2024

The article analyzes in detail the stress-strain state during additive manufacturing using silicon bronze CuSi3Mn1 (БрКМц3-1), which is widely used in the machine-building industry for the manufacture of bushings, spring parts, and parts of chemical apparatus. The high cost of non-ferrous copper-based alloys makes it important to use Welding Arc Additive Manufacturing (WAAM) technologies. The processes of layer-by-layer surfacing of silicon bronzes lead to residual stresses at the tensile strength of the material, which can eventually provoke the development of critical defects in the form of cracks. Based on the simultaneous solution of the finite element method for the equations of heat balance and mechanics of a solid deformed body, the peculiarities of temperature distribution and parameters of the stress-strain state for the developed model of a triangular equilateral prism, which is additively generated from CuSi3Mn1 bronze, are determined. Verification of the experimental model with the calculated one was carried out by comparing the thermal cycles of surfacing. Based on the anal-ysis of the results of numerical modeling, it was found that the nature of the temperature change and the magnitude of its decrease in the corresponding layer after the deposition of subsequent layers are the same and do not depend on the deposition trajectory, and the largest residual equivalent plastic deformations are formed in the first layer with a gradual decrease inthe value in each subsequent deposited layer, which is associated with a decrease in the degree of volume of the VAT prism from the 1st to the 10th layer. The lower layers are characterized by a volumetric stress state due to the presence of rigid binders in the form of the substrate and the upper welded layers, which increases the probability of cracking in these layers during the cooling stage due to a decrease in the material's strength below σB< 170 MPa in the temperature range of 475-550 °C
Exploring Challenges and Strategies for Online Classroom Interaction
Authors: Entusiastik Entusiastik
Published: February 2024

Research has indicated the importance of classroom interaction as one of the determinant factors for language learning to be successful. However, with the fact that the online learning mode has been a new norm in the education context, creating a supportive classroom interaction is considered challenging. Both the teachers and students rely on the technological resources to interact both synchronously or asynchronously. Although theoretically, the online platforms are available to make interaction more explicit, it seems that interaction among learners during online class is either more difficult to create or is not fully encouraged. This research intends to answer two questions, firstly, what challenges students face which potentially prevent them from participating in classroom interaction? And secondly, what can be done to improve the quantity and quality of classroom interaction to maximize learning. An online survey is conducted to explore possible challenges in creating interactive learning activities as well as strategies to improve classroom interaction. It is expected that the research may offer insights for instructors and educators to have a more meaningful classroom interaction and engage learners more effectively.

Authors: Daheri Mirzon , Dwi Julianti Cica
Published: February 2024

Tradition is a habit passed down from time to time across generations. Each tradition has values useful for maintaining life personally and socially, including the Cambuk Lidi tradition in Derati Village, Kota Padang District, Rejang Lebong, Indonesia. Researchers explore its values by conducting observations, interviews, and documentation. Interviews were conducted with community leaders, namely the chairman and members of the Badan Musyawrah Adat (BMA), religious officials, village officials, and perpetrators who were sentenced to Cambuk Lidi (people who had been Cambukped). The results show that at least two important values are contained in this tradition, namely the values of faith and moral values. The value of faith is to believe and carry out all His commands. The moral value of Cambuk Lidi is to build a responsible attitude, have a sense of shame and immediately correct themselves from mistakes.

Published: February 2024

The increasing sugar intake has become a global issue due to its impact on health. The survey conducted in Jakarta revealed that the median sugar intake for adolescents and adults is 18.8 g/capital/day and 24.5 g/capital/day, respectively. The government has taken several ways to reduce sugar intake, one of which is by using labels on packaged food. Therefore, this research aims to investigate the knowledge and attitude towards nutrition fact panels with sugar intake in Indonesian adolescent. This research was a cross-sectional study using an online questionnaire for adolescents in Indonesia with age range between 15-18 years old. Data on sociodemographic, mass media exposure, knowledge, and attitude were collected through online questionnaires, while sugar intake was assessed through online SQ-FFQ interviews. The study’s findings showed that the majority of respondents were women (90%), with parents having below 12 years of schooling on average. Additionally, the median monthly pocket money and pocket money for food and drinks below IDR 300,000 and IDR 200,000, and mass media exposure occurred more than 3 times per month. More than half of the respondents displayed good knowledge (51.7%) and a positive attitude towards NFP (60.8%), with the majority having high sugar intake (53.5%). There is a relationship between knowledge of NFP, mass media exposure, and mother education with sugar intake in adolescents. It recommended to enhance knowledge of NFP among adolescents and parents through social media platforms, posters and TV ads to enable them select and consume appropriate foods.
Factor Xa inhibitors versus warfarin in severely obese patients with venous thromboembolism or atrial fibrillation
Authors: Tierce Haley Elizabeth , Lusk Kathleen Ann , Kitten Amanda Kristine , Long Christina Marie
Published: February 2024

Objectives:

Clinical data for the safety and efficacy of Factor Xa (FXa) inhibitors in severely obese patients is limited. Additional information is needed to assess the risks and benefits of using FXa inhibitors in this patient population.

Materials and Methods:

A single-center and retrospective chart review was conducted in severely obese patients (body mass index [BMI] >40 kg/m2 or weight >120 kg), who received rivaroxaban, apixaban or warfarin for venous thromboembolism (VTE) treatment or prevention of stroke and systemic embolism in non-valvular atrial fibrillation (AF). The primary endpoint was treatment failure, defined as recurrent VTE in VTE treatment or stroke, transient ischemic attack or systemic embolism in AF within one year of anticoagulation initiation. Secondary endpoints included a composite of major bleeding rates and clinically relevant non-major bleeding (CRNMB) rates.

Results:

Seventy-three patients were included in the final analysis consisting of 43 patients in the FXa inhibitor arm (apixaban [n = 33] and rivaroxaban [n = 10]) and 30 patients in the warfarin arm. The rate of treatment failure was similar between the FXa inhibitor and warfarin groups (4.7% vs. 6.7%; P = 0.814). Although not statistically significant, major bleeding and CRNMB occurred less frequently in patients receiving FXa inhibitors compared to warfarin (9.3% vs. 23.3%; P = 0.182). Subgroup analysis in patients with BMI >50 kg/m2 or weight >150 kg demonstrated similar efficacy and safety outcomes. The use of non-recommended dosing was more common in the apixaban group compared to the rivaroxaban group.

Conclusion:

FXa inhibitors (apixaban and rivaroxaban) appear to have similar efficacy and safety compared to warfarin in severely obese patients. Larger prospective studies are needed to confirm these results.

Principles and Metaphysics of Modernity: Towards Modernization in Yakutia
Authors: Pudov Aleksey G.
Published: February 2024

In the 21st century, an urgent topic is the assessment of the dynamics of cultural development of ethnic groups living in the natural and climatic conditions of the North and the Arctic and bearing conservatism towards their traditional culture, which has become the basis for centuries of survival and adaptive flexibility. In the period of total relativization of postmodern values, the task of making a balanced choice in one’s spiritual heritage and historical practice remains important. The aim of the article is to identify the potential of modernity for ethnic cultures of the North-East of Russia, which experienced incomplete modernization on the wave of bourgeois transformations and Soviet socio-cultural modernization in the 19th—20th centuries, to determine the options for the development of modern culture against the background of the deadlock of postmodernity, which constrained the productive options for the development of “culture of traditions” by the phenomena of global mass culture.

The general scientific methods and the method of symbolic ontologisation of culture, explicating the synthesis of interaction of symbolic constructs of metaphysical and mythological nature, underlying the regularities of ethno-cultural dynamics in the aesthetic sphere and organic modernization transformations in general, have been applied.

It is shown that the metaphysics of modernity determines the dynamic stability of ethnoculture, allowing to realize its undiscovered potential through the principles of modernity, independently reproduce these principles, making the transition of ethnos from the culture of mimesis to the culture of the birth of primordiality. The quality of modernity gives the Sakha a sense of metaphysical continuity with the stages of evolution of European culture, freeing them from mythological predetermination of fate, including by intensive innovative knowledge-intensive economy. The synthetic synergy of “ethno” and “modern” reveals the potential for cultural growth institutionalized by the paradigm of ethnomodernity, which resolves the contradictions of modernity, bringing ethnoculture to the idea of socio-cultural and scientific-technological development, dignity and natural human rights.

Single Molecule Magnets (SMMs) emulate permanent magnets and are highly regarded for their role in compact information storage and molecular spintronics. Their behavior is primarily governed by magnetic anisotropy, expressed through parameters like the axial zero-field splitting (D) and orientation of magnetic anisotropy (gx, gy, gz) in mononuclear transition metal complexes. Low-coordinate mononuclear transition metal complexes stand out for their substantial anisotropy and higher blocking temperatures. However, understanding the intricate interplay between these parameters poses a significant challenge, often beyond traditional magneto-structural correlations. Hence, machine learning (ML) tools have been embraced to address these complexities. By employing an ML model based on Co-ligand bond length and angle relative to the pseudo-C3 axis, this study effectively rationalizes variations in D values, g-factors, and rhombic anisotropy, crucial for determining magnetic properties. Leveraging a dataset of 627 molecules, the research explores ML's potential in predicting magnetic anisotropy parameters in three-coordinate Co(II) complexes, achieving a minimal mean absolute error (MAE) of approximately 17 cm⁻¹ and high accuracy levels exceeding 95% for classification tasks. These insights offer valuable guidance for the development of innovative single-ion magnets.

Published: February 2024

The biaryl motif is important for many fields within chemistry and the life sciences. Thus, new cheap and expeditious strategies to forge these aryl-aryl bonds are valuable. Herein, we report the discovery of conditions permitting the room temperature arylation of acetanilides, and related amides, using ubiquitous aryl boronic acid reagents. Critical to the success of this method is the use of Selectfluor as a cheap, sustainable alternative oxidant to silver-based additives and the deployment of a bulky QuinOx ligand supporting the palladium catalyst.

Soil contamination by metallic trace elements (MTEs) poses a significant environmental challenge, with far-reaching implications for human health and biodiversity. In this context, the exploration of biological methods for chelating MTEs has emerged as a promising, environmentally sustainable approach. Notably, certain metallophores, particularly pyoverdine, demonstrate effective scavenging properties, offering a viable solution. This study involved screening forty-five Pseudomonas isolates for their potential to extract these metals from contaminated soils. Additionally, we monitored the synthesis of various metabolites, including siderophores, indole-3-acetic acid (IAA), ammonia, hydrogen cyanide (HCN), and phosphate solubilization. The purified siderophore fraction was characterized using Fourier Transform Infrared Spectroscopy (FT-IR). Results indicated a notably higher level of siderophore production in P. lactis, P. atacamensis, and Pseudomonas sp. PS11. Particularly, the pyoverdine from P. lactis demonstrated a higher binding affinity for bromine, tin, rhodium, and lead. Our findings conclude that pyoverdine extracted from P. atacamensis exhibited an enhanced capacity for copper ion removal (49.63%), surpassing that of P. lactis (47.65%) and the control agents (EDTA and citric acid, ranging from 43.11% to 27.58%).
On integration with respect to filter

This article is devoted to the study of one generalization of the Riemann integral. Namely, in the paper, it was observed that the classical definition of the Riemann integral over a finite segment as a limit of integral sums, when the diameter of the division of the segment tends to zero, can be replaced by a limit of integral sums over a filter of sets, which can be described in a certain "good way". This idea was continued, and in the work we propose a new concept - the integral of a function over a filter on the set of all tagged partitions of a segment. Using of filters is a very good method in questions related to convergence or some of its analogues in general topological vector spaces. Namely, if the space is non-metrizable, then the concept of convergence is introduced precisely with the help of filters. Also, using filters, you can formulate the concept of completeness and its analogues. The completeness of spaces is one of the central concepts of the theory of topological vector spaces, since Banach spaces are complete. That is, using a generalization of the completeness of spaces constructed using filters, we can explore various generalizations of Banach spaces. We study standard issues related to integration. For example, does the integrability of the filter function imply its boundedness? The answer to this question is affirmative. Namely: the concept of filter boundedness of a function is introduced, and it is shown that if a function is integrable over filter, then its integral sums are bounded over the filter, and this function itself is bounded in the classical sense. Next, we showed that the filter integral satisfies the linearity property, namely, the integral over filter of the sum of two functions is the sum of the filter integrals of these functions. In addition, we can to subtract the constant factor from the sign of the integral over filter. We introduce the concept of an exactly tagged filter, and with the help of such filters we study the filter integrability of unbounded functions on a segment. We give an example of a specific unbounded function and a specific filter under which this function is integrable. Next, we prove a theorem that describes unbounded filter-integrable functions on a segment. The last section of the article is devoted to the integration of functions relative to the filter on a subsegment of this segment.
