Published: February 2025

This study explores the creation process of "Weightless," a relaxation music piece by Marconi Union, with a focus on its compositional elements and how frequencies are manipulated. The aim is to deepen the understanding of both educators and undergraduate students regarding the use of Digital Audio Workstations in composing music, thereby promoting digital literacy within 21st-century music education. The research employs a descriptive qualitative method, utilizing an exploratory approach and content analysis.Through this analysis, it becomes clear that "Weightless" effectively incorporates slow tempos, minimalistic textures, and gradual changes in dynamics to create a relaxing atmosphere. The frequency analysis highlights the importance of low frequencies (ranging from 20 to 200 Hz), which contribute to a sense of depth and tranquility. In contrast, mid and high frequencies are carefully balanced to ensure they do not overwhelm the listener. Additionally, the loudness analysis reveals a smooth dynamic range, with an average level of -13.9 LUFS and no sudden peaks, which guarantees a pleasant listening experience across various playback devices. Overall, these findings emphasize the critical role of precise frequency manipulation and loudness control in producing effective relaxation music, providing valuable insights for both music composition and education.

Published: February 2025

The issue of manipulation in the problem of environmental damage is a topic that never expires. Literary works as a medium to disseminate good values and morals in life. One of them is the drama script Mata Air Mata (MAM) by Lab Teater Ciputat which raises environmental issues. Dissemination of this good message can be done because the MAM script is a collection of collective unconsciousness that needs to be traced to the markers and signifieds of the characters it presents. This study will discuss the collective unconsciousness in the form of archetypes, semiotic archetypes, and character ideologies from an ecocritical perspective, in the MAM drama script. The limitation of the problem focuses on the dominant archetype of each character in the MAM drama script, namely the character of Kabut Asap. The research methodology uses qualitative descriptive. The discussion uses the theory of the collective unconscious of Carl Gustav Jung and the semiotics of Charles Sanders Peirce. The results of this study show that the dominant archetype of the Kabut Asap character, namely the trickster, shows the ideology of anthropocentrism.
Exploring Te Kooti’s 1886 Te Umutaoroa prophecy as a climate adaptation framework
Authors: Rangiwai Byron
Published: February 2025

This paper is the beginning point of reflecting on and exploring the 1886 Te Umutaoroa prophecy, given by Te Kooti Arikirangi Te Tūruki, as a climate adaptation framework, inspired by the Toi Rito Toi Rangatira - Rangatahi Climate Leadership Programme. Selected by my hapū, Patuheuheu and Ngāti Haka, I joined this programme aimed at rangatahi Māori involved in Deep South Research projects. Despite initial reservations about my age, my kaumātua encouraged my involvement, seeing potential benefits for our hapū. The programme was transformative, enriching my understanding of climate leadership and integrating contemporary perspectives with traditional wisdom. This experience led to a deeper exploration of the Te Umutaoroa prophecy, promising restoration of land, dignity, and sovereignty. The prophecy’s eight mauri provide a foundation for a hapū-centred climate adaptation framework. Climate change, driven by industrialisation, threatens ecosystems, and Māori communities, are particularly vulnerable. Integrating mātauranga Māori with scientific methods offers holistic, culturally meaningful solutions. Te Umutaoroa’s principles—spirituality, land stewardship, hapū well-being, faith/belief, healing, discovering hidden potential, conflict resolution, and returning to ancestral lands—guide potential adaptation strategies. This paper presents Te Umutaoroa as a framework to strengthen the resilience of Patuheuheu and Ngāti Haka against climate change, advocating for further research and collaboration to refine and implement these strategies, ensuring they align with hapū values.

Tackling Sustainability in Today’s Building Climate
Authors: Gosav Cosmin-Ionuţ
Published: February 2025

The construction industry is composed of the entirety of our built environment, from small houses to apartment buildings, to bridges and offices and as such, it serves as the basis on which our society develops, providing context for our world. Since late 2019, with the start of the COVID-19 pandemic the world as we know it has suffered from a social, economical and political shift, as activities have halted in an attempt to stop the spread of the virus. Restrictions and regulations meant to guard our livelihood have had lots of unpredictable and unwanted consequences, and industries from across the globe, especially the building industry have deteriorated, devolved or diminished, resulting in a decrease in quality of life overall. This, combined with the effects of global warming accumulating over the years makes us really consider the importance of building sustainable and minimizing the impact of our lives over the medium we design and thrive. In this regard, the legislative bodies governing the European Union have given guidelines and suggestions on how and why everyone should build with efficiency in mind and trying to lessen the waste that the process of building produces. As such, from 2021 all new buildings must comply to the nZEB standard, meaning they have to be designed with sustainability as a key element. As new technology and engineering feats commence, how can architects adapt to this shift in the design paradigm? And how can this be achieved in underdeveloped countries, where there are many other factors which can be detrimental in the outcome of the built project?

Authors: Bunea Georgiana , Atanasiu Gabriela Maria
Published: February 2025

This paper analyses the response of a set of RC frame structures, with different structural parameters, under seismic actions. The purpose is to observe how the structural response varies depending on the structural and seismic action parameters. For this analysis, four structural parameters were selected to be modified and each structure thus obtained was subjected to three seismic actions. In this study case, the structural response is given by the fundamental vibration period of the damaged structure Tf
, the maximum displacement dmax
and the inter-story drift ratio IDR. Two of these values, i.e. Tf
and IDR, are related directly to the post-seismic structural damage state, which is one of the most important indicators of the structural response.

Published: February 2025

For the last two decades, Serbian family policies have gone through several changes in accordance with contemporary trends and changes in family life and also influenced by EU regulations and recommendations. Current legislation is in line with the gender equality principle, enabling both parents to exercise their rights and to pursue a work-life balance. However, when it comes to paid parental leave, the Serbian legal framework is considered inflexible in terms of choosing the combination of length of leave and the remuneration amount. In this paper, we argue that Serbian parental leave policies must be analysed in relation to the specific context of a (unfinished) post-socialist transition at the semi-periphery of Europe, population decline and strong familism. The burden of parenthood is still predominantly on women’s shoulders, even though ideas about a “new fatherhood”, more involved in child rearing, have become more widespread. Whether they are employed or not, women/mothers remain the primary caregivers, while the typical Serbian family can be described as a male breadwinner model.

Authors: Nowak Błażej , Zwierzykowski Piotr
Published: February 2025

Today’s computer and telecommunications networks, irrespective of the technical solutions and technologies used to build them, are multi-service in nature. The modelling of networks and nodes in such networks is still an important research problem. The article presents the results of a simulation study of multi-service switching networks in which service-specific priorities are introduced. A specially developed and executed simulation programme was used to carry out the research. In the study, we considered the two most optimal placement of the switching elements performing the functions of multicast traffic splitting in a 3-stages Clos switching network. During the tests, it was assumed that the switching network supported a mixture of multiservice unicast and multicast traffic streams. The aim of the research conducted is to investigate the impact of the introduction of priorities on the loss probability of multicast traffic in a multiservice switching network. The results obtained from the simulation are presented on the graphs in the form of points with confidence intervals.

Authors: Pouliou Anna , Kehagia Fotini , Meselidis Christos
Published: February 2025

The objective of this paper is the investigation of the parameters that influence the crash occurrence in the case of an unexpected incident. It draws inspiration from the Safety System Approach, which is built on the position that serious injury and death in transport networks cannot be ethically acceptable. To this end, the research takes into consideration parameters regarding both the road environment and the human factor. A driving simulator experiment takes place with the participation of 56 drivers, and the employment of the appropriate equipment (driving simulator, physiological parameters sensors and software, camera, synchronization software). It investigates the effect of different road and environment parameters (road category and complexity of the environment, visibility conditions), parameters of the driver (age, gender, mental workload), physiological parameters of the driver (heart rate, skin conductance, skin temperature) and the reaction time of the driver to the unexpected incidents, as well as the way of reaction (brake, maneuver, both, none). Furthermore, parameters of the vehicle are taken into consideration (speed, acceleration, headway). Α mixed logistic regression model is being developed for examining the relationship between the under study explanatory variables and the crash occurrence in unexpected incidents.
The Paradox of Urban Travel Behavior on Public Transport Use: A Bibliometric and Critical Theoretical Review
Authors: Kaamah Abdallah Faisal , Kombe Wilbard Jackson , Sakijege Tumpale
Published: February 2025

The fundamental aim of transport policies especially on public transport is to get the most ridership by meeting the demands of users. The study provides a holistic view of public transport use by understanding the integration of the constructs of the Theory of Planned Behavior (TPB) and the Random Utility Theory (RUT). A bibliometric and systematic literature search and review approach was used to identify, evaluate, and synthesize all relevant research on urban travel behavior and public transport use. The paper followed the PRISMA guidelines to ensure the transparency and reproducibility of the review process. The application of the guideline helped in the selection of 78 articles to understand public transport use, behaviors, and rationality taking into account the TPB and the RUT. It emerged from both theory’s tenets that public transport rationality actions are made, based on some inherent conditionalities that influence urban travel behavior. The model shows that the constructs of the TPB are a good predictor of travel intentions, but it does not fully explain actual travel behavior because it does not take into account RUT constructs. Based on the results, the study proposes an integrated system for transport and travel behavior that seeks to understand the rationality (conscious and unconscious actions) of transport users through the clarification of relationships between TPB and RUT constructs. The understanding of the model can helpfully predict how transport users will make decisions based on conscious and unconscious actions, which can help policymakers develop better policies for sustainable transport.
Advanced Optimization Models for Bandwidth Provisioning and Routing in Fixed Microwave Backhaul Networks
Authors: Mehadji Djamil Abdelhak , Kaddour Mejdi
Published: February 2025

This paper addresses the problem of determining bandwidth allocation and traffic routes in fixed microwave networks such that overall bandwidth cost is minimized while traffic demands are satisfied with a required reliability level. These networks exhibit high variability in link throughput as modulations schemes are adapted dynamically to ensure acceptable bit-error rate at the receivers according to external conditions such as the weather. First, we formulate an optimal optimization approach based on mixed-integer linear programming, which is subsequently reinforced by inserting problem-specific valid inequalities based on global network capacity to reduce the search space and eliminate the unfeasible bandwidth/modulation combinations, thus reducing the number of decision variables. Then, we introduce a Lagrangian-based heuristic that provides near optimal solutions while reducing drastically the computation time. In comparison to previous work, our experimental results show that our approaches are capable to solve large real-world network instances in an effective manner. Furthermore, the results evaluate the impact of reliability and transported traffic demands on bandwidth cost.

Published: February 2025

Background
Plastic and reconstructive surgery is a unique surgical specialty that is often misunderstood. Unlike other specialties, it encompasses a wide range of procedures, considering anatomical regions, specific diseases, and patient characteristics. This study aims to assess the awareness levels (knowledge and perception) of plastic surgery among medical students and interns at Jouf University's College of Medicine.
Methods
A cross-sectional study was conducted between December 2023 and March 2024 at Jouf University, involving 558 medical students and interns. A sample size of 228 was calculated using OpenEpi software with a 99% confidence level. Participants were selected through simple random sampling, and data were collected using a validated questionnaire covering demographics, knowledge, and perceptions of plastic surgery. Data analysis was performed using Statistical Package for the Social Science (SPSS), with Chi-squared tests applied and a significance level set at p < 0.05.
Results
The study found that 79.1% of participants had limited knowledge of plastic surgery, and only 4.7% had prior experience with a plastic surgery rotation. Burns were the most recognized condition treated by plastic surgeons (89.8%), with the internet being the primary source of information (72.6%). Significant associations were found between knowledge and factors such as age, academic year, and having a medical family background (p < 0.05). Despite 53.4% of participants demonstrating good knowledge, only 20.1% expressed interest in pursuing a career in plastic surgery, citing competitiveness and ethical concerns as barriers.
Conclusion
This study highlights a gap in medical students' knowledge and perception of plastic surgery at Jouf University. To address this, the curriculum should incorporate clinical rotations and educational sessions covering both reconstructive and cosmetic surgery.

Arabic language learning in grades 10 and 12 still uses conventional methods which apparently have an impact on the lack of vocabulary mastery, seen from the arabic language scores that are below average. This is reflected in the arabic exam scores which are below average. The purpose of this study is to encourage student activeness and improve vocabulary learning outcomes. This research uses experimental method by comparing 2 learning models, namely conventional learning model and cooperative learning model. Conventional learning models tend to be passive and focus on lectures. Cooperative learning, on the other hand, involves collaborative and interactive activities. This model proves that conventional learning produces below-average scores, and cooperative learning of answer play type produces higher scores and has a significant positive impact on the mastery of Arabic mufrodat. It is proven from the pretest and posttest results of 7 to 18, this proves that cooperative learning is an effective alternative compared to the conventional method. Further research can explore how the same cooperative learning model can be applied to other language skills, this will help to see if this model is also effective in improving overall Arabic language skills.

Arabic textbooks in Islamic schools contain many loanwords from Arabic into Indonesian, which facilitate students’ language acquisition due to their similarity and ease of memorization. Vocabulary mastery is crucial, as its deficiency often poses challenges in learning Arabic. This study analyzes the root words of loanwords and their absorption process in Arabic textbooks. Using a qualitative literature review approach, data were collected through document analysis and examined using content analysis. The findings reveal that most loanwords follow a triliteral root pattern 126 words, followed by triliteral roots with one additional letter 16 words, two additional letters 4 words, and quadriliteral roots 3 words. The absorption process occurs through direct adoption, phonological adaptation, and morphological adaptation. This study contributes to the development of more effective vocabulary teaching methods for Arabic learning. However, it is limited to Arabic textbooks published by the Ministry of Religious Affairs, excluding those from private publishers. Future research is recommended to explore loanwords in Arabic textbooks from private publishers to understand variations in absorption processes and root words, as well as to assess the effectiveness of loanword-based teaching methods in enhancing students’ Arabic vocabulary mastery.

Objetivo: Avaliar a eficácia que as intervenções no estilo de vida proporcionam para a prevenção de doenças cardiovasculares. Revisão bibliográfica: As doenças cardiovasculares (DCV) destacam-se como uma das principais causas de mortalidade global, estando associadas a fatores como sedentarismo, obesidade, tabagismo e a adoção da dieta ocidental, caracterizada pelo consumo excessivo de gorduras e carboidratos. Embora os benefícios de mudanças no estilo de vida, como a prática regular de exercícios físicos e a alimentação saudável, sejam amplamente reconhecidos, muitas pessoas enfrentam barreiras para incorporar essas práticas no cotidiano. Ainda assim, estratégias que incentivam hábitos saudáveis têm potencial para reduzir significativamente a morbimortalidade e gerar economias ao sistema de saúde. Considerações finais: As intervenções no estilo de vida demonstram elevada eficácia na prevenção de DCV, conforme evidenciado por estudos que destacam os benefícios de mudanças comportamentais. Nesse direcionamento, pesquisas futuras devem explorar abordagens integradas e multifatoriais, tais como a alimentação balanceada, a atividade física e o suporte psicossocial, ampliando a eficácia e a aplicabilidade dessas intervenções.

Objective

Diabetic retinopathy (DR) is a prevalent and serious complication among individuals with diabetes, significantly compromising their visual acuity and overall quality of life. Lysine acetyltransferase 5 (KAT5), an essential catalytic subunit of the nucleosome acetyltransferase of the H4 complex, is implicated in the development of various diseases, including neurological disorders, breast cancer, and lung cancer. However, the function of KAT5 in DR remains poorly understood. This study aims to investigate the influence of KAT5 on autophagy (Atg) during DR.

Material and Methods

Experiments were conducted using streptozotocin (STZ)-treated rats to induce diabetes and observe changes in KAT5 expression and its effect on Atg. Retinal tissues and RF/6A cells were utilized to analyze the expression levels of various proteins and their involvement in Atg and apoptosis. KAT5 depletion and Atg7 knockdown were performed to further understand their roles in the process.

Results

The eyeballs of STZ-treated rats showed increased expression of KAT5. Depletion of KAT5 attenuated STZ-induced DR injury in rats. The retinal tissues of STZ-treated rats exhibited reduced expression of B-cell lymphoma-2 (Bcl-2) and increased levels of BCL-2-associated X protein and cleaved caspase 3, which could be reversed by KAT5 depletion. STZ treatment induced expression of Beclin-1 and microtubule-associated protein 1 light chain 3B in retinal tissues, and KAT5 knockdown blocked this effect. In monkey retinal choroidal endothelial ( RF/6A) cells, high glucose (HG) treatment decreased 5-ethynyl-2’-deoxyuridine-positivecells and increased terminal deoxynucleotidyl transferase dUTP nick-end labeling-positive cells, which were reversed by KAT5 depletion. KAT5 depletion also attenuated HG-induced apoptosis and Atg in RF/6A cells. Mechanistically, KAT5 depletion reduced histone H3 lysine 27 acetylation and ribonucleic acid ( RNA) polymerase II enrichment on the Atg7 promoter, leading to a decrease in the messenger RNA ( mRNA) and protein expression of Atg7. Atg7 knockdown suppressed Atg in RF/6A cells under HG conditions and reversed the effect of KAT5 depletion on cell apoptosis and Atg.

Conclusion

The findings suggest that KAT5 contributes to DR by modulating Atg through epigenetic regulation of Atg7. KAT5 emerges as a valuable target for DR treatment, providing a fresh perspective on the disease’s pathogenesis and laying the foundation for the development of potential therapeutic strategies.

Objectives

The anterior fontanelle (AF) is a fibrous gap between skull bones and is most important among all fontanelles in clinical examination of neonates and children in the first 2 years of life. There is a lack of normative data on AF size in our region, and hence, establishing normative data and understanding its associations with various perinatal factors can facilitate clinical evaluations and early diagnosis of potential abnormalities. The study aims to generate normative data on AF size in neonates and investigate its associations with gender, mode of delivery, weight at birth, head circumference and gestational maturity.

Material and Methods

This study was conducted over 3 months in the outpatient department section of the Special Care Newborn unit in an associated hospital of medical college in North India, including normal term neonates born between 37 and 42 weeks. The study excluded pregnancies with antenatal risk factors and neonates with certain defined conditions and measured AF size using the Keisler and Ricer method.

Results

In a study of 217 neonates (114 males and 103 females), the mean AF size was 2.43 ± 0.60, with 97.70% having an AF size between 0.6 and 3.6 cm. No significant gender differences were found in AF size. Neonates born through lower-segment caesarean sections had significantly larger head circumferences compared to those born through normal vaginal delivery. Weak positive correlations were observed between AF size and gestational maturity.

Conclusion

The study shows that AF size is influenced significantly by gestational maturity only and not by weight at birth, head circumference, gender or mode of delivery. These results could help paediatricians in assessments of normal and abnormal fontanelle size in neonates. The high percentage of neonates with good-sized fontanelles between 0.6 and 3.6 cm warrants further investigation to determine if this is due to rampant Vitamin D deficiency of mothers in this part of India or influenced by measurement methods.

The extensive use and environmental release of perfluoroalkyl substances (PFAS), often referred to as “forever chemicals”, has raised significant health and environmental concerns. Due to their persistence and resistance to natural degradation, PFAS appear in concerningly high concentrations, e.g., in our drinking water. Among these substances, perfluorooctanoic acid (PFOA) is particularly prevalent. This study explores the application of synthesized zirconium terephthalate (UiO-66) metal-organic framework (MOF) gel for highly efficient removal of PFOA from water. The UiO-66 gel not only maintains the structural stability of its powder form but also offers improved ease of handling. Structural characterization by PXRD and TEM analyses revealed the gel's nanocrystalline structure (~20 nm in size), which was further confirmed by electron diffraction. Quantitative NMR spectroscopy demonstrated a PFOA removal efficiency of 96%. The successful absorption of the polyfluoro compound into the UiO-66 gel after filtration was confirmed by the detection of fluoride within the gel structure using STEM-EDS elemental mapping. In addition, to demonstrate the potential of developing membrane platforms as practical and scalable solutions for environmental remediation, the performance of a MOF gel filter was successfully tested.
