Objective. The COVID-19 pandemic has caused a variation in the circulation of respiratory pathogens. Our aim was to analyze the epidemiology of severe acute respiratory infections (SARI) in children during 3 years of the COVID-19 pandemic, in comparison with a previous period. Patients and Methods. An observational study was conducted in a tertiary hospital in Spain, which analyzed the frequency and characteristics of patients admitted for SARI in the Pediatric Intensive Care Unit (PICU) during the COVID-19 pandemic (1 March 2020 to 28 February 2023), compared to pre-pandemic period (1 March 2017 to 29 February 2020). Results. A total of 268 patients were included (59.6% males). The median age was 9.6 months (IQR 1.7 – 37). In the pre-pandemic period, there were 126 admissions with an average of 42 admissions/year. During the pandemic, there were 142 admissions, observing a significant reduction in admissions in the first year (12 admissions/year), in contrast to 82 admissions during the third year, which represented an increase of 95% compared to the average of admissions/year in pre-pandemic. In addition, in the last year there was evidence of an increase in viral coinfections in relation to pre-pandemic period (54.9% vs 39.7%; p=0.032). There were no differences in length of hospital stay or PICU stay. Conclusions. During the last year, coinciding with low rates of hospitalization for COVID in Spain, we observed a notable increase in admissions to the PICU for SARI. Probably, the prolonged period of low exposure to pathogens due to the measures adopted during the pandemic might have caused a decrease in population immunity with a rise in severe respiratory infections.

Published: December 2023

The current paper attempted to measure the effects of digital storytelling (DST) on motivation, self-directed learning (SDL), and vocabulary learning of Omani EFL students. To achieve this goal, 40 learners participated in this study, divided equally into control and experimental groups. Three main instruments were used in this study as pretests and posttests, including the Self-Rating Scale of SDL adopted from Williamson (2007), the Motivation Questionnaire adapted from Mehdiyev et al. (2017), and the researcher-designed vocabulary test. Both groups received face-to-face instructions; however, the experimental group was exposed to extra sessions for creating DST projects. The results of the study in motivation and SDL showed that both groups progressed as the results of instructions, but the experimental group was slightly better. However, in the vocabulary test, the experimental group significantly performed better than the other group. These findings can help teachers, institutions, and students better use the technological resources in language learning environments.
Familiarity and Self-Perceived Competence to Communicate in a Second Language
Authors: Olobia Leoncio P.
Published: December 2023

Communicating in English as a second language spoken inside classroom, among friends and schoolmates, relies on comfort and proficiency. Viewed from an autoethnographic lens, this paper aims to explore and analyze pressing issues besetting a student from communicating fluidly in English as a second language in a classroom context. The methodology of the study consists of the autoethnographer’s self-reflections of classroom learning, analyzed using the interpretive paradigm of the self as located within the culture. The paper reveals that speaking in English as a second language largely depends on self-motivation, economic status, social background, and technological capacity. Moreover, self-perceived competence to communicate manifests in a person’s readiness and openness to communicate a foreign language that impact one’s individual and cultural identity.

This work summarizes the results of structural stability, electronic properties and phonon dispersion studies of biocompatible ZrO2 compound in its cubic (c-ZrO2), tetragonal (t-ZrO2) and monoclinic (m-ZrO2) phases. The authors found that the monoclinic phase of zirconium dioxide is the most stable among the three phases in terms of total energy, lowest enthalpy, highest entropy, and other thermodynamic properties. The presence of rather weak frequencies for m-ZrO2 also confirms the monoclinic phase as a stable conformation of zirconia. Our analysis of the electronic properties showed that during the m-t phase transformation of ZrO2, the Fermi level first shifts by 0.125 eV toward higher energies and then decreases by 0.08 eV in the t-c cross-section. The band gaps for c-ZrO2, t-ZrO2, and m-ZrO2 are 5.140 eV, 5.898 eV, and 5.288 eV, respectively. Calculations to study the effect of 3.23, 6.67, 10.35 and 16.15 mol%Y2O3 on the structure and properties of m-ZrO2 showed that the enthalpy of m-YSZ decreases linearly and accompanies further stabilization of zirconium dioxide. Doping-induced phase transitions of ZrO2 were discovered under the influence of Y2O3 doping, due to which the position of the Fermi level changes and the band gap decreases. It has been established that, not only for pure systems but including those doped with Y2O3, the main contribution to the formation of the conduction band is made by the p-states of electrons.

Published: December 2023

This work was designed to evaluate the unmodified and modified natural dye obtained from a sensitizer in dye-sensitized solar cells using experimental and computational approaches. Natural dye (APPE) was extracted from Avocado pear (Persea Americana) peels and chemically modified into nanocomposite by a one-pot reaction with silver nitrate. The modified dye was characterized by UV-Vis spectroscopy, X-ray diffraction (XRD) spectroscopy, Energy dispersive spectroscopy (EDS) and transmission electron microscopy (TEM). The APPE and APPE-AgNPs composite show maximum wavelength of light absorption at 542 nm and 493 nm respectively. Both APPE and APPE-AgNPs were evaluated as sensitizers for dye-sensitized solar cells (DSSC). The APPE-AgNPs dye afforded a higher power conversion efficiency of 0.93% compared to 0.44% for APPE. Current-voltage responses and photo-electrochemical properties were determined at one sun illumination. The electronic properties of the major phyto-compounds in the dye, namely perseorangin and cyanidin associated with light harvesting and sensitization were modeled using a quantum chemical computational approach. The power conversion efficiency of APPE-AgNPs obtained from this study compares with other plant-based dye sensitizers and hence could be deployed for practical application.
The Challenges of University Strikes on Students: A Case Study from Madagascar
Authors: Nirindrainy Avosia Francis
Published: December 2023

Achieving higher education in Madagascar is a challenge given the various barriers students must overcome to gain admission into university. However, once enrolled, students often face additional challenges that affect their ability to obtain education. One such challenge is the frequent occurrence of labor strikes at the university. Using a qulatiative approach, this study conducted a survey among alumni and current university students in Madagascar to investigate the perceived causes and consequences of university strikes in Madagascar. The findings from the survey (N=31) showed that all students have experienced delays in their education program ranging from 1-6 months and that strikes were the primary cause of these delays. Governmental lapses in salary payments and scholarship disbursements were identified as the primary catalysts for these disruptive strikes. Despite expressing frustration with the strikes, students directed their discontent primarily at a national level, underscoring a more extensive disillusionment with the government's management of the education sector. Notably, students affirmed their belief in the genuine dedication of their teachers to their education. The study unveils the emotional and financial toll of university strikes, with participants reporting anxiety, frustration, and concerns about education quality. Financially, the strikes compound challenges, affecting job market entry, rent payments, family dynamics, and overall education costs. Alarmingly, there was a consensus among participants that university strikes have led to student disenrollment. These findings serve as a crucial warning for Madagascar, signalling potential erosion of trust in the education system. If students lose faith, there is a risk of reduced educational pursuit or even international migration, contributing to increased brain drain. This poses serious implications for the holistic development and progress of Madagascar. Urgent interventions are imperative to address the root causes of university strikes, restore confidence in the education system, and mitigate the far-reaching consequences on the nation's future

Published: December 2023

Autoimmune pancreatitis (AIP) is a complex, poorly understood disease gaining increasing attention. "Clinical Characteristics and Outcome of AIP Based on Serum IgG4 levels," investigated AIP with a focus on serum immunoglobulin (Ig) G4 levels. The 213 patients with AIP were classified according to serum IgG4 levels: Abnormal (elevated) and normal. Patients with higher IgG4 levels exhibited a more active immune system and increased relapse rates. Beyond IgG4, the IgA levels and age independently contributed to relapse risk, guiding risk assessment and tailored treatments for better outcomes. However, limitations persist, such as no IgA correlation with IgG4 levels, absent data on autoantibody-positive AIP cases critical for Asian diagnostic criteria, and unexplored relapse rates in high serum IgG AIP by subtype. Genetic factors and family histories were not addressed. As the understanding and referral of seronegative AIPs increase, there's a growing need for commercially available, highly sensitive, and specific autoantibodies to aid in diagnosing individuals with low or absent serum IgG4 levels.

Published: December 2023

There is rapidly increasing uptake of GLP-1 (glucagon-like peptide-1) agonists such as semaglutide worldwide for weight loss and management of non-alcoholic steatohepatitis (NASH). remains a paucity of safety data in the vulnerable NASH cirrhotic population. We report herein the first documented case of liver decompensation and need for liver transplant waitlisting in a patient with NASH-cirrhosis treated with semaglutide. Rapid weight loss led to the development of ascites and hepatic encephalopathy and an increase in the patients Model for Endstage Liver Disease-Na (MELD-Na) score from 11 to 22. Aggressive nutritional supplementation was commenced and the semaglutide was stopped. Over the following months she regained her weight and her liver recompensated and her MELD-Na decreased to 13, allowing her to be delisted from the transplant waitlist. This case serves as a cautionary tale to clinicians using semaglutide in the cirrhotic population and highlights the need for more safety data in this patient group.

Amidst the current shift towards sustainable development and a low-carbon economy, it is important to assess the preparedness of mining companies for implementing large-scale technology modernization programs. The extent of modernization and the level of the company’s involvement are the factors determining the nature of modernization transformations. Major modernization of production makes it possible to address the challenges of improving corporate social and environmental responsibility, including industrial safety issues in mining operations. When implementing technology modernization programs, it is important to focus on environmentally-oriented objectives while improving operational efficiency. The mining industry, characterized by unique technological solutions, often necessitates unconventional modernization measures, entailing substantial investments in research and development (R & D). In Arctic deposit development, a higher level of technological advancement, including digital technologies and automated control systems, is imperative. Digital solutions, automation, and robotization should be integrated into modernization programs in the mining sector. Our research methodology is based on the summary and synthesis of theoretical and methodological approaches to assessing the effectiveness of modernization measures and developing a typology of technology modernization models. This study aims to refine conceptual approaches to the typology of organizational and economic models of technology modernization and to assess the effectiveness of modernization programs in the context of mining in the Arctic. The article delineates the fundamental principles of technology modernization and substantiates the effects arising from modernization measures, using mining companies functioning in the Arctic economic zone as an illustrative case study. The article proposes a typology of technology modernization models based on criteria developed by the authors, among which are key technology, management effects, and key approaches to efficiency assessment. It is emphasized thatadvanced technology modernization models should holistically reflect both economic and socio-ecological effects.

Published: December 2023

Progress toward achieving SDG 6 ("Clean Water and Sanitation") is monitored by means of thirteen global indicators. However, insufficient data from countries, including Russia, underscore the need to assess regional water supply as well as its effective and sustainable use. This study aims to comparatively assess water use in northern regions based on UN-defined sustainable development criteria, utilizing information from Rosstat, The National Information Agency "Natural Resources", and the FAO's Global Information System for the period from 2007 to 2020. The study is based on statistical and comparative analyses, the Decoupling Diamond model, and sustainability window (SuWi) analysis. Its findings indicate high water availability across all regions, aligning with the "low water stress" category under SDG 6.4.2 (threshold ≤25%). The Falkenmark water index shows that water availability doesn't hinder economic growth in northern regions. Regional variations in water use across industries are discussed, which impact productivity (SDG indicator 6.4.1) and water intake intensity (water capacity of GRP). Water use productivity highlights the efficiency of recycled water, reducing intake and increasing productivity. Regions with low intake intensity (below 1.4 m3/thousand rubles, which is the target according to the Water Strategy) and high water capacity of the gross product were identified. Using the Decoupling Diamond model, the study assessed economic growth as a function of water use. The sustainability window method revealed environmental constraints on economic growth related to water use in northern regions. These results offer insights into water use in Arctic regions in the context of the Sustainable Development Goals and Water Strategy implementation. They are essential considerations for regional development programs.

Development of a mathematical model of underwater towing, based on single- and double-link rod models of towing lines
Authors: Tishchenko Maksim S. , Ivanovskii Nikolai V.
Published: December 2023

This paper develops a mathematical model of underwater towing by the example of a complex fishing complex "vessel - vaer - trawl" by calculating its traction and speed characteristics.

The tow line is an important factor when towing an underwater object because it can affect the stability and maneuverability of the towing vessel. If the shaft is too long, it can create a lot of drag and make it difficult to move the boat. On the other hand, if the shaft is too short, it may cause the towed object to sink too deeply and potentially damage the object or towing equipment. Consequently, it is critical to select the proper towing system settings based on the size and weight of the object being towed, the depth of the stroke, and the environmental conditions.

Existing methods for writing models of tug - towing object systems, namely, methods based on stationary and non-stationary nature of the vaer selection process are investigated.

The paper presents a comparative analysis of single-link and two-link rod models of towing lines. The main errors in the construction of trajectories of towed objects using these types of towing lines are revealed.

In particular, one of the results of the study is, building a model of the system "ship - vaer - towed object", which has a similar accuracy index to the more complex two- and three-link lines.

Published: December 2023

The study examines the energy efficiency performance of hotel façades in relation based on the annual cooling energy consumption simulation. In achieving the objective, two case studies of high-rise city hotels are selected within the locality of Penang, Malaysia. The case studies are selected based on the year of construction coupled with the architectural styles encompassing conventional and modern design of hotel facades. In the traditional design of hotel facades, passive design elements including proper selection of window and wall materials alongside window-to-wall ratio (WWR) are less significant. Comparatively, elements of passive design in the modern hotel facades are notable. In assessing the thermal performance of the hotel façade, a case study of the conventional and modern high-rise city hotels in Penang are selected to undergo hourly cooling load simulation of hotel guestroom using the DesignBuilder program in establishing the hotel’s energy efficiency performance.

An electrode is a vital transmission tool of electrical charges that erodes a workpiece surface in die-sinking electrical discharge machining (EDM). However, the demanding requirements of the geometrical complexity and accuracy of an electrode significantly affected its manufacturing cost and time. Therefore, rapid tooling (RT) was attempted to improve electrode manufacturing. This research aims to verify the application of the FDM electrode in die-sinking EDM. Furthermore, the metallization and the machining performance of the FDM electrode were also studied. Fused Deposition Modelling (FDM) was utilized to fabricate a cylindrical electrode core made of Polyethylene Terephthalate Glycol (PETG). In primary metallization, the electrode core was immersed in copper paint. Next, the coated PETG substrate was electroplated in secondary metallization at a current density of 0.023 A cm-2 for 168 hours (7 days). The electrolyte consists of 80 g/ℓ copper (II) sulphate pentahydrate and 20 ml/ℓ sulphuric acid. The machining performance of FDM electrode such as material removal rate (MRR), electrode wear rate (EWR) and surface roughness (SR) was benchmarked with a copper electrode. Copper coating with an average thickness of 334 µm was successfully electroplated on the surface of the FDM electrode. Additionally, the FDM electrode was able to machine the mild steel workpiece with 1 mm infit at a peak current of 16 A and pulse-on time of 50 µs without suffering premature electrode failures such as edge failure, delamination, distortion and rupturing. Lastly, the machining performance of the FDM electrode was comparable to the copper electrode in terms of MRR, EWR and SR. The potential of the FDM electrode in EDM machining is proven successful and can be investigated further to enhance the performance of this electrode.

Efficient investigation tools are required to elucidate the changes in climatic change caused by various climate processes, variables, and socioeconomic development activities around the world. In this study, we track the changes of daily rainfall at three flood-prone sites in Terengganu between 2012 to 2017. In recent years, topological data analysis (TDA) has been applied in many fields of data analytics to rank, classify, and cluster time series datasets. In this work, we employ Persistent Homology to quantify and identify topological patterns from a rainfall data. A sliding window (SW) approach is used for each 1D rainfall dataset to embed in higher dimensions before computing its Persistence Diagrams (PD). The topological information obtained from PD, namely connected components (H0) is then retrieved and vectorized in the form of Persistence Curves (Persistence Landscape (PL), Persistence lifetime Curve (PLC), and Persistence Lifetime Entropy (PLE)) to identify unusual rainfall patterns. We employ various types of L1-norms from these Persistence vectors to identify anomalies in rainfall data which can be used as an early warning flood system. The irregular pattern of Persistence lifetime and Persistence entropy mismatch the actual flood events suggesting that the irregular points may not be as closely related to flood risk. However, PL analysis of the irregular points shows match of about 59% to the flood events.It is expected that other determining factors, for example, land use, cloud cover, and wind information, which can be obtained via satellite gridded data may increase the predictability of flood events thus promotes an effective flood risk management strategies.

The provision of timely feedback with useful guidance towards the correct solution is very important within the learning process of higher education students. This paper describes an implementation of timely feedback in a 3rd year electrical engineering undergraduate course, Communication Principles (SKEE 3533) that was carried out during COVID-19 pandemic. Given the substantial depth of this course syllabus, it is important that students receive sufficient feedback on their understandings on current topic before moving to the next. The implementation of this assessment technique is carried out using online quiz assessment through Google quiz platform. Two types of guided explanation are given in the feedback: text explanation for simple, conceptual based questions, and video explanation for design and calculation-based questions. For the latter, YouTube platform is used to perform the video-based explanation. Study on student feedbacks was carried out using a routine, official university’s survey while the impact on student performances was analysed based on their acquired grades in the SKEE3533 course. Findings demonstrate positive outcomes from the routine university survey and course grades which revealed the method’s potential in improving student satisfactions and performances on the assessment aspect of teaching component.

Since 2017, the Ministry of Education has introduced Basic Vocational Skills subjects that able special students to master basic living skills in their schooling years underlying Secondary School Standard Curriculum – Special Education (KSSM –PK). The biggest challenge for individuals with ASD is to be independent and get jobs after schooling. Hence, beginning in 2017, Secondary School Standard Curriculum – Special Education (KSSM –PK) has introduced the Basic Vocational Skills subject, which students must master during their schooling years. From the preliminary study, many teachers revealed that they face difficulty delivering lessons primarily related to teaching and learning materials to enhance ASD students mastering living and vocational skills. Designing and developing effective teaching and learning aids, especially for children with special education needs are in alarming stages. Parents and caregivers indicated they face insufficient enhancement and practice learning tools for their children, especially after school hours. The guidebook and extra exercise books are essential for them to master their learning while at home. In response to the gap mentioned earlier and decipher the myriad of potential uses of Augmented Reality (AR) as an assistive educational technology, the current study aimed to design and develop a differentiated instructional pedagogical kit (Kit-MASAK) with AR to assist children with special education needs especially ASD students master in basic vocational skills Preparing and cooking skills). Methodologically, a total 3 students were involved in the phenomenological study. The preliminary analysis of the data summary across the case studies revealed that the Kit MASAK successfully brought contemporary content into the classroom, leading to an exciting teaching and learning environment among students. Furthermore, this study also provides several significant implications for the research and practice.

Education aims to form a generation of faith and piety as mandated by the law. And realizing this goal is not easy so it requires a process and cooperation from various parties, including PAI teachers who have their homework related to moral degradation that is increasingly becoming. Especially in this era where technological sophistication has advanced so rapidly that social media has emerged. So it takes a more interesting packaging of material from PAI teachers to students in the learning process to hit the heart so that the hope can be applied in everyday life. So the purpose of this study is to describe the role of social media for PAI teachers in the student learning process at school. The method used is a literature study with a qualitative descriptive approach, data collected from various relevant sources, and then concluded. The results showed that social media became a separate innovation for PAI teachers during the learning process with students, especially in the current era, and it acts as a means of learning from several sources, as a means of administrative documentation and integration, then as a means of planning both strategically and management and finally as a means of control that includes evaluation and measurement. And with all of that, learners will easily absorb information, develop their potential, and be able to learn.
