Published: December 2023

The objective of this paper is to evaluate the effects of creep feeding supplementation during the preweaning phase on the growth performance and metabolic characteristics of Nellore heifers. Forty-two female Nellore calves (age = 100 ± 25 d; initial body weight (BW) = 113.4 ± 16.6 kg) were randomly assigned to the following treatments: control, where calves received mineral mix supplementation (n = 21); supplemented in creep feeding, where calves received 6 g/kg BW of a concentrate supplement (n = 21) during a period of 140 d. In the postweaning phase, all heifers received 6 g/kg BW of a concentrate supplement during a period of 210 d. Supplemented heifers had a greater average daily gain (ADG) than control heifers during the preweaning phase and, consequently, were heavier at weaning and at the end of the growing phase (p < 0.05). However, preweaning supplementation did not influence (p > 0.05) the body measurements or BW at the end of the growing period. Greater (p < 0.05) rib fat was observed in supplemented heifers. Concentrations of metabolites were not affected by preweaning supplementation (p > 0.05). Thus, supplementing heifers in the preweaning phase improved growth performance of weaning and body adiposity.

Authors: Huang An-Chi , Huang Chung-Fu , Shu Chi-Min
Published: December 2023

With the continual acceleration of urbanization, the amount of urban infrastructure and the quality of public services are increasing in many cities. A pressing concern in this context is the growing problem of incompatible fire protection construction, indicating a need for urban fire stations with well-planned layouts. However, research on optimizing the layout and placement of fire stations by considering the various factors affecting station layouts is lacking. The current study addressed this gap by establishing an optimal fire station layout by using a geographic information system (GIS) and elucidated the trends of GIS application in firefighting and rescue operations. The study’s findings reveal the benefits of avoiding blind spots, enhancing the selection of fire station sites, and optimizing service coverage. Furthermore, this study optimized the layout of CZ city’s downtown fire stations, which could enhance CZ city’s firefighting capabilities.
Developmental Outcomes among Children within the Context of Maternal Incarceration: Findings from a Study of Family Inequality
Authors: McGee Zina T.
Published: December 2023

This research addresses behavior difficulties and maladaptive coping among African American children and adolescents, and the manner in which these outcomes differ among those with incarcerated mothers. The study also provides an in-depth analysis of the experiences of mothers during and after their incarceration. Earlier investigations suggested that mothers’ victimization and offending, including drug use, are related to children’s emotional and behavioral outcomes. Hence, this research extends an ongoing project by investigating the nature of this relationship using aggregate data on adolescent health outcomes. Generally, most research addresses parental incarceration, typically followed by negative responses of male youth. Less research has evaluated the outcomes of parents’ incarceration on African American children and adolescents specifically. This is particularly true among those with incarcerated mothers. Additionally, examinations have highlighted the role of fathers’ incarceration on negative family functioning, yet we know less about the impact of mothers’ imprisonment and re-entry on children’s behavior. Many of these mothers are single and live in poverty, and their economic situations lead to higher risks of recidivism, deleteriously affecting their children. Moreover, several of them are raising children while experiencing traumatic mental health concerns amid drug usage with minimal support or treatment. For the current project, special attention is also placed on the mothers’ experiences with contact with children, prior history of substance abuse, mental illness, treatment for drug and alcohol problems, and coping with separation from children in an attempt to reveal the subsequent, harmful impact on children’s behavioral adjustment.

Published: December 2023

While various quantifiable physical attributes have been found to contribute to athletes’ performance, there is a lack of scientific literature focused on examining how they relate to success during competition performance. The aim of this study was to investigate different countermovement jump (CMJ)-derived force–time characteristics and their utility in distinguishing high from low performers within a measure of on-court contribution (i.e., minutes per game played). Twenty-nine collegiate athletes (n = 15 males and n = 14 females) volunteered to participate in this investigation and performed CMJs on dual force plates sampling at 1000 Hz, weekly over the course of their basketball season. The athletes’ average of their three best test-days across the season was used for further analysis. To identify their on-court contribution, athletes were divided into groups with high and low minutes per game, based on a median-split analysis. The findings suggest that at the overall group level (i.e., both genders), the modified reactive strength index (mRSI) and braking rate of force development (RFD) revealed the greatest between-group magnitudes of difference, with athletes playing more minutes per game showing greater performance. At the team-specific level, the braking RFD, average braking velocity, and mRSI were shown to be the greatest differentiators between groups for the men’s team. The women’s high-minutes group displayed greater magnitudes of mRSI and jump height. By identifying the neuromuscular qualities seen in top performers within their respective populations, the attributed physical performance underpinning these qualities may be identified, providing practitioners with insights into physical performance qualities and training methodologies that have the potential to influence basketball performance.
Vulnerability Assessment for Port Logistics System Based on DEMATEL-ISM-BWM
Authors: Qian Yuntong , Wang Haiyan
Published: December 2023

In order to identify and assess the vulnerability of the port logistics system itself, this paper further improves the methodology on the basis of previous studies by using the Deterministic Experimentation and Evaluation Laboratory (DEMATEL) and Interpretive Structural Modeling (ISM) methods to study the correlation between the vulnerability factors of the port logistics system, and the best-worst method (BWM) to identify the key vulnerability points of the system. The results of the study showed that in terms of the correlation between the factors, port consolidation capacity and average arrival time are the most direct factors affecting the vulnerability of the port logistics system, and the strength of government regulation and coordination and the level of port management are important indirect factors affecting the vulnerability of the port logistics system. This paper also found that port loading and unloading facilities and natural disasters are the main vulnerabilities affecting the port logistics system itself. Port enterprises should focus on reducing the vulnerability of the system by strengthening the above aspects. The model constructed in this paper can also be applied to future research on the resilience and sustainability of port logistics.

Arecoline is a pyridine alkaloid derived from areca nut in the Arecaceae family. It has extensive medicinal activity, such as analgesic, anti-inflammatory, and anti-allergic. However, the toxicity of Arecoline limits its application. Most current studies on its toxicity mainly focus on immunotoxicity, carcinogenesis, and cancer promotion. However, there are few systematic studies on its hepatotoxicity and mechanisms. Therefore, this research explored the mechanism of hepatotoxicity induced by Arecoline in rats and analyzed endogenous metabolite changes in rat plasma by combining network toxicology with metabolomics. The differential metabolites after Arecoline exposure, such as D-Lysine, N4-Acetylaminobutanal, and L-Arginine, were obtained by metabolomics study, and these differential metabolites were involved in the regulation of lipid metabolism, amino acid metabolism, and vitamin metabolism. Based on the strategy of network toxicology, Arecoline can affect the HIF-1 signaling pathway, MAPK signaling pathway, PI3K-Akt signaling pathway, and other concerning pathways by regulating critical targets, such as ALB, CASP3, EGFR, and MMP9. Integration of metabolomics and network toxicology results were further analyzed, and it was concluded that Arecoline may induce hepatotoxicity by mediating oxidative stress, inflammatory response, energy and lipid metabolism, and cell apoptosis.
Differential Urban Heat Vulnerability: The Tale of Three Alabama Cities
Authors: Fall Souleymane , Coulibaly Kapo , Quansah Joseph , El Afandi Gamal
Published: December 2023

Urban heat vulnerability varies within and across cities, necessitating detailed studies to understand diverse populations’ specific vulnerabilities. This research assessed urban heat vulnerability at block group level in three Alabama cities: Birmingham, Montgomery, and Auburn-Opelika. The vulnerability index combines exposure, sensitivity, and adaptive capacity subindices, incorporating Landsat 8 satellite-derived Land Surface Temperature (LST), demographic, and socioeconomic data using factor analysis and geospatial techniques. Results showed strong positive correlations between LST and impervious surfaces in Auburn-Opelika and Montgomery, with a moderate correlation in Birmingham. An inverse correlation between LST and Normalized Difference Vegetation Index was observed in all cities. High LST correlated with high population density, varying across cities. Birmingham and Montgomery’s central areas exhibited the highest heat exposure, influenced by imperviousness, population density, and socioeconomic factors. Auburn-Opelika had limited high heat exposure block groups, and high sensitivity did not always align with exposure. Correlations and cluster analysis were used to dissect the heat vulnerability index, revealing variations in contributing factors within and across cities. This study underscores the complex interplay of physical, social, and economic factors in urban heat vulnerability and emphasizes the need for location-specific research. Local governance, community engagement, and tailored interventions are crucial for addressing unique vulnerabilities in each urban context.

Published: December 2023

This pilot study explores alterations in miRNA profiles among pregnant women and their neonates upon receiving different doses of COVID-19 vaccines. Blood samples, including maternal blood (MB) and neonatal cord blood (CB), collected from five pregnant women were scrutinized using the miRNA PanelChip Analysis System, identifying nine distinct miRNAs, including miR-451a and miR-1972, which exhibited significant downregulation with two vaccine doses in both MB and CB. When compared with women vaccinated with four doses, miR-486-5p, miR-451a, and miR-1972 in the two-dose group also showed notable downregulation. Evaluating recipients of three and four doses, miR-423-5p and miR-1972 expression were significantly reduced in both MB and CB. Further comparative analysis highlighted a decline in miR-223-3p expression with increasing vaccine doses, while miR15a-5p, miR-16-5p, and miR-423-5p showed an upward trend. Notably, miR-451a, miR-1972, and miR-423-5p levels varied across doses and were associated with pathways such as “PI3K-Akt”, “neurotrophin signaling”, and “cortisol synthesis”, suggesting the profound influence of vaccination on diverse molecular mechanisms. Our research has uncovered that escalating vaccine dosages impact miRNA profiles, which may be associated with the immunological response mechanisms in both the mother and fetus, thus indicating a substantial impact of vaccination on various molecular processes.

Published: December 2023

The interrelatedness of social-structural aspects and psychological features with vaccination intention provides the context to explore personal psychological features related to vaccination. Specifically, we focused on general decision making and vaccine-related dispositions, and their contribution to the intention to vaccinate, within post-pandemic circumstances, after the imposed possibility of choosing a vaccine brand. Our study aimed to map the function (promotive, protective, risk, vulnerability) of a set of personal psychological aspects in the intention to vaccinate among people holding different social roles regarding the vaccination. We surveyed three samples of people: healthcare providers (HPs), parents, and laypeople, within the post-pandemic context. Negative vaccine attitudes lower intention to vaccinate in all regression models (all βs ranging from −0.128 to −0.983, all ps < 0.01). The main results indicate that, regardless of the sample/social role, there is a shared attitudinal core for positive vaccination intention. This core consists of [high] trust in large corporations, government, and healthcare systems, as well as perceived consensus on vaccine safety/efficacy and experience of freedom (protective factors), and [low] vaccination conspiracy beliefs, trust in social media, and choice overload (risk and vulnerability factors, respectively). There are no common promotive factors of intention to vaccinate: for parents, perceived consensus on vaccines, and trust in corporations and the healthcare system, play such roles; for HPs, the experience of freedom is obtained as a unique promotive factor. In contrast, for laypeople, no unique promotive factors were found. Our findings provide insights into the function of psychological factors of vaccination intention across different social roles, particularly healthcare providers, parents, and laypeople, and emphasize the need for tailored immunization interventions in the post-pandemic landscape.
Next-Generation Sequencing for the Detection of Microbial Agents in Avian Clinical Samples
Authors: Afonso Claudio L. , Afonso Anna M.
Published: December 2023

Direct-targeted next-generation sequencing (tNGS), with its undoubtedly superior diagnostic capacity over real-time PCR (RT-PCR), and direct-non-targeted NGS (ntNGS), with its higher capacity to identify and characterize multiple agents, are both likely to become diagnostic methods of choice in the future. tNGS is a rapid and sensitive method for precise characterization of suspected agents. ntNGS, also known as agnostic diagnosis, does not require a hypothesis and has been used to identify unsuspected infections in clinical samples. Implemented in the form of multiplexed total DNA metagenomics or as total RNA sequencing, the approach produces comprehensive and actionable reports that allow semi-quantitative identification of most of the agents present in respiratory, cloacal, and tissue samples. The diagnostic benefits of the use of direct tNGS and ntNGS are high specificity, compatibility with different types of clinical samples (fresh, frozen, FTA cards, and paraffin-embedded), production of nearly complete infection profiles (viruses, bacteria, fungus, and parasites), production of “semi-quantitative” information, direct agent genotyping, and infectious agent mutational information. The achievements of NGS in terms of diagnosing poultry problems are described here, along with future applications. Multiplexing, development of standard operating procedures, robotics, sequencing kits, automated bioinformatics, cloud computing, and artificial intelligence (AI) are disciplines converging toward the use of this technology for active surveillance in poultry farms. Other advances in human and veterinary NGS sequencing are likely to be adaptable to avian species in the future.

Food products based on grain raw materials are products of everyday consumption and are in high demand among consumers. This type of product has a low moisture concentration, so it has a longer shelf life. If the production and storage technology is not followed, undesirable physical and chemical processes and pest infestation may occur in grain products. All this leads to deterioration in the quality and safety of products. It is possible to reduce the likelihood of such situations by using digital tools, such as digital marking, electronic document management and business process modeling. Digital labeling will allow for traceability at all stages from harvesting to the consumer, an electronic document management system will transfer information between stages to the required extent, and a process management system will prevent errors at the processing stage.

From French-Cluniac to Castilian : A Sacramentary-Pontifical in 12th-Century Castile
Authors: Lopez-Mayan Mercedes
Published: December 2023

Cet article examine un sacramentaire-pontifical conservé à la Bibliothèque Capitulaire de Tolède (Ms. BCT, 37-27), seul manuscrit liturgique de ce type existant en Castille avant le 13ème siècle. Une analyse complète a permis de dater le livre du troisième tiers du XIIe siècle à Tolède, de distinguer les aspects français de sa liturgie et de ses enluminures et de proposer qu’il ait été écrit pour l’archevêque de Tolède, Cerebruno (1167-1180). En outre, l’étude propose une analyse préliminaire du panorama complexe des manuscrits liturgiques produits en Castille au XIIe siècle, dans lesquels se retrouve distinctement une influence franco-clunisienne, intrinsèquement liée au rite romain introduit en Castille à la fin du XIe siècle. Cette influence française a persisté pendant des décennies et a été modifiée progressivement par de nouvelles contributions espagnoles.

Published: December 2023

Uncertainty estimation is critical for numerous deep neural network (DNN) applications and has drawn increasing attention from researchers. In this study, we demonstrated an uncertainty quantification approach for DNNs used in inverse problems based on cycle consistency. We built forward–backward cycles using the available physical forward model and a trained DNN solving the inverse problem at hand and accordingly derived uncertainty estimators through regression analysis on the consistency of these forward–backward cycles. We theoretically analyzed the cycle consistency metrics and derived their relationship with the uncertainty, bias, and robustness of neural network inference. To demonstrate the effectiveness of these cycle-consistency-based uncertainty estimators, we classified corrupted and out-of-distribution input image data using widely used image deblurring and super-resolution neural networks as test beds. Our blind tests demonstrated that our method surpassed other models in detecting previously unseen data corruption and distribution shifts. This study provides a simple-to-implement and rapid uncertainty quantification method that can be universally applied to various neural networks used to solve inverse problems.
Le corps augmenté. De la fiction à la réalité
Authors: Boudou Nadine
Published: December 2023

Notre objectif est de montrer comment des films de science-fiction ont traité l’augmentation des facultés corporelles et cognitives. Ces imaginaires cinématographiques permettent de nous interroger sur l’intérêt de telles innovations. Ils dressent le tableau d’un monde dans lequel l’artificialisation et la mécanisation de nombreuses activités mènent à une perte de contrôle sur celles-ci, ce qui nous ferait courir le risque, à terme, d’être privés de nos qualités d’humains. Cependant, nous montrerons que ces films ne s’interrogent pas pour autant sur la viabilité de ce type de société. En effet, ces fictions n’insistent pas sur les contraintes que ces transformations font pourtant peser sur l’environnement. Face à la crise écologique l’emprise des innovations technologiques sur l’ensemble des sociétés, loin d’apparaître comme une solution, risque au contraire d’être identifiée comme une partie du problème.
Réincarner le corps de demain par la science-fiction spéculative : Les employés (2018) d’Olga Ravn
Authors: Marto Joaquín Jesús
Published: December 2023

Dans cet article, nous proposons de réfléchir à l’impact des nouvelles technologies sur le corps à travers l’étude de l’expérience épistémique qu’offre la science-fiction spéculative. Plus précisément, nous montrerons comment le texte littéraire préfigure les enjeux que nos technologies les plus convoitées, attendues et fantasmées pourront avoir sur l’humain de demain. Le roman d’Olga Ravn, Les employés (2018), sera le terrain d’analyse pour étudier de quelle manière le corps augmenté, la vie extraterrestre et l’intelligence artificielle impactent le corps, et par le fait même bouleversent l’entendement de notre propre personne et du monde qui nous entoure. Ainsi, nous verrons qu’un avenir où il est davantage question de progrès technique que social peut engendrer une réalité désincarnée et surtout une humanité aliénée.
Le sujet décentré et la honte prométhéenne dans De Synthèse de Karoline Georges (2017)
Authors: Lansen Greta
Published: December 2023

De Synthèse brise la conception du corps organique comme producteur de sens. Par le dédoublement identitaire et l’ouverture transcendante, le roman défie la distinction cartésienne fondamentale entre un corps singulier et une âme. En utilisant tout ce qui est en son pouvoir, la protagoniste-narratrice ambitionne une libération complète de son corps organique. Pour la protagoniste, le sang et la chair deviennent au fur et à mesure plus abstraits que la représentation des corps augmentés virtuels qu’elle se crée elle-même. Au lieu de définir son individualité à travers son corps organique, la protagoniste transfère son existence vers un lieu virtuel, dégradant son corps organique en un corps-machine qui se trouve définitivement à l’extérieur de sa subjectivité. En fin de compte, l’effort de la protagoniste de se transformer en image ne fait que détourner l’attention du fait que le récit suit en réalité le schéma le plus classique des romans, à savoir celui de la quête familiale.

Objetivo: Evaluar la eficacia del dispositivo artesanal de asistencia respiratoria no invasivo de administración de presión positiva continua en las vías respiratorias (CPAP) Wayrachi en comparación con la cánula de alto flujo comercial (CAF) para el tratamiento de pacientes con SARS-CoV-2. Métodos: Estudio realizado en el Hospital Honorio Delgado Espinoza de Arequipa (Hospital COVID-MINSA Arequipa). Se evaluó a las historias clínicas de pacientes con SARS-CoV-2, de severidad moderada o grave que requerían asistencia respiratoria no invasiva, hospitalizados en el servicio de medicina interna durante la 2da ola de COVID en el Perú. Se realizó un análisis de supervivencia considerando los días a la muerte comparando al Wayrachi con la CAF. Se exploró el efecto de las variables sobre la muerte mediante una regresión de Cox. Resultados: Se evaluaron 114 pacientes tratados con Wayrachi (56,44%) y 88 con CAF (43,5%), observándose una frecuencia de muerte de 34,2% y 34,1% respectivamente. Al comparar la frecuencia de muerte, o su sobrevida, en ambos manejos no se observó una diferencia significativa (p=0,986 y p=0,928), esto se mantuvo en el modelo multivariado. Conclusión: El CPAP Wayrachi tuvo resultados similares a los presentados por el equipo CAF comercial lo que lo indica como una opción eficaz para el manejo de pacientes COVID que requieran soporte respiratorio no invasivo.
Learners’ Satisfaction with Adaptive Learning Systems
Authors: Lim Seo Hong , Lim Lyndon , Lim Rebekah Wei Ying
Published: December 2023

To enhance diverse students’ learning experiences, tertiary educational institutions are increasingly adopting adaptive technologies. Although there are views that adaptive learning platforms contribute to learning within higher education, efficacy research of such systems yields mixed results. This is an indication that more could be studied concerning how adaptive learning can be efficacious within higher education contexts particularly when cognate studies have mostly discussed how cognitive measures differ between learners who engaged and those who did not engage with an adaptive learning system. Beyond cognitive measures such as achievement scores provided by adaptive learning systems, this brief paper proposes that learner satisfaction towards such systems - as an imperative factor due to its direct and significant relationship between users and the system - needs to be examined, in part to evaluate the efficacy of adaptive learning systems. Given the complexity of learner satisfaction as a construct, such investigations have the potential to illuminate important factors of system optimizations, developments, and interventions that provide crucial guidelines for higher education institutions to implement successful adaptive learning courses that meet students’ satisfaction.

Recently, a microporous copper inverse opals (CIO) wick material has been utilized in the thermal management of microelectronics as it significantly enhances heat transfer performance with capillary-fed boiling, providing a high critical heat flux of up to ~1100 W/cm2. In this study, we numerically investigate the thermomechanical reliability of the CIO structures with a finite element method. The mechanical stress of ordered and graded CIO structures is simulated under the conditions of external shear load and boiling-induced thermal expansion. Different geometric parameters, including pore diameter and the neck-to-pore ratio of ordered CIO, and overlap distance and pore gradient of graded CIO, have been parametrically studied. Based on the effective mechanical properties extracted with the representative volume element (RVE) method, the mechanical response of the porous structure is being further understood. The von Mises yield criterion is applied to determine the fracture of the copper structure. The reliability of ordered CIOs is assessed by evaluating the maximum von Mises stress and shear stress under the shear load, showing lower stresses with larger pore diameters and smaller pore-to-neck ratios. In contrast, a decrease in thermal stresses is found to appear in ordered CIOs with small pores and large neck-to-pore ratios under boiling conditions. The thermomechanical reliability of graded CIOs is analyzed with different pore gradients and overlap distances. The stress distribution of graded CIO structures indicates maximum stresses near the Si-Cu interface in the shear test, while the interfaces between layers of CIOs are more vulnerable under boiling conditions. In terms of the pore gradient effects, the graded CIO with a larger gradient tends to be more fragile due to the larger stresses at the interfaces between pore diameters induced by the increased differences in pore diameter.

Due to the necessary security for the airport and flight, passengers are required to have strict security check before getting aboard. However, there are frequent complaints of wasting huge amount of time while waiting for the security check. This paper presents a potential solution aimed at optimizing gate setup procedures specifically tailored for Chicago O’Hare International Airport. By referring to queueing theory and performing Monte Carlo simulations, we propose an approach to significantly diminish the average waiting time to a more manageable level. Additionally, our study meticulously examines and identifies the influential factors contributing to this optimization, providing a comprehensive understanding of their impact.

Published: December 2023

The primary symptom of Alzheimer's disease is memory impairment, which is a neurodegenerative condition. The manifestation of these symptoms can be attributed to the impairment of the cerebral nerve responsible for cognitive functions such as learning, thinking and memory. Alzheimer’s disease is a prominent cause of mortality and lacks a definitive curve. However, appropriate medicinal interventions have demonstrated the potential to mitigate the progression and severity of the condition. This study presents the comparison of Convolutional Neural Network (CNN) models, namely ResNet50, VGG19 and VGG16 architectures, as an approach to construct an automated classification system for Alzheimer’s disease in future. The study utilises Magnetic Resonance Imaging (MRI) datasets to identify MRI datasets of individual with Alzheimer’s disease (AD), Cognitively normal (CN), mild cognitive impairment (MCI), early mild cognitive impairment (EMCI), and late mild cognitive impairment (LMCI). In the conducted experiment, the study achieved accuracy rates of 91.18% and 94.56% while utilising an epoch size of 2. The accuracy results indicate that the VGG16 model outperforms the ResNet50 model. The utilisation of automated Alzheimer’s disease classification holds potential as an auxiliary tool for healthcare professionals in determining the stage of Alzheimer’s disease hence facilitating the administration of suitable medicinal interventions.

The cliff terrace site, Woodstock Rocks, was exploited occasionally by hominins from the Earlier Stone Age to the Iron Age. A small excavation uncovered an Acheulean quartzite workshop with many flakes, but lacking large cutting tools and without organic preservation. Below the workshop site, a ferricrete river terrace cements Acheulean lithics that include large cutting tools, giant flakes and heavy-duty scrapers. A palaeomagnetic study reveals reversed polarity, implying that the ferricrete formation likely took place during the Matuyama Chron and that the lithic assemblage is older than 780 000 years. The cliff face was painted expansively, but both the Bushman and Iron Age farmer art is faded. There are some rare images including a wild dog, a bird and a possible genet. The southern edge of the cliff terrace has Middle and Later Stone Age lithics on the surface and talus slope, as well as grindstones, and ceramics that include Bambata sherds from six vessels. The proximity to the Mokolo River and sources of rocks for knapping, as well as smooth rock walls for painting ensured repeated Woodstock Rocks visits (not necessarily occupation) for generations of Homo sapiens visitors, as well as earlier hominins.

Amid changes in world politics and the chaos of musical culture in the 20th century, the need for research on the fusion of classical music and jazz emerged. Therefore, this study reveals the characteristics that the jazz elements in “Kapustin’s Piano Concerto No. 2 Op. 14” (Concerto) combined with classical music to contribute to the evolution of modern music. Analysis of various aspects such as musical form, tempo, rhythm, melody, harmony, and instrumentation based on the orchestral score revealed that Kapustin’s Concerto exhibited musical diversity and innovation through the fusion of classical music and jazz, and was a work that went beyond the boundaries of tradition and experiment. Kapustin developed a unique musical style by incorporating jazz elements into classical music and demonstrated the potential of the third stream. Kapustin’s musical fusion was clearly revealed as a new trend in modern music in which various musical elements interacted. These results can help find and create new works by promoting the popularization of classical music and innovation of popular music.
