Authors: He Yuhong 
Published: February 2024

Abstract
Under the development needs of the times, cultivating students’ ability to master rhythms is crucial to improving the quality of English talent cultivation. The vocal rhythm teaching method is used to establish an optimization model for music teaching in colleges and universities in this paper. In this teaching model, a real-time music beat recognition method combining music styles is proposed based on recurrent neural network and long and short-term memory neural network, and the feature fusion of mutual attention mechanism is utilized to carry out emotion recognition of multimodal music, to accurately control the music learning effect of students. Concerning the effectiveness of the optimization model of music teaching in colleges and universities, it is applied to the teaching practice, and the data are quantitatively analyzed in terms of music recognition ability and teaching effect. The results show that the recognition rate of the multimodal music emotion recognition method for 10 kinds of emotion categories of folk songs reaches up to 0.98, and the mean value of the final music literacy assessment scores of the experimental class after the experiment is increased by 2.89-3.38 points compared with that before the experiment, and the positive classroom mood shows a very significant difference at the level of 5%. The application of the optimization mode of college music teaching based on vocal rhythmic teaching methods in the practical teaching of music courses can cultivate students’ interest in music, help students improve their aesthetic level, and promote their overall development.

Published: February 2024

Abstract
In the context of aesthetic education infiltration action, the construction of musicology majors in colleges and universities needs to design diverse teaching contents. This paper analyzes the dynamic impact of the construction of musicology professional skill course clusters with the help of the variable impulse response function of the VAR model and explores the promotional relationship between aesthetic education and music professional literacy. Aiming at the problem that the VAR model cannot reflect the time-varying features and nonlinear features, the TVP-VAP model is used to capture the time-varying features, and at the same time, the Bayesian algorithm is used to calculate the parameters in the model to improve the operation efficiency of the model. After the design was completed and put into practical use, the professional knowledge scores of musicology majors in colleges and universities and students’ aesthetic ability scores in January-October 2023 were selected as databases to establish the TVP-VAR model. When implementing aesthetic education, the response value is 0. From the second month onwards, aesthetic education will have a lasting positive effect and level off, and the response value is around 0.003. The value of the impact effect of students’ professionalism on aesthetic education is 0, which indicates a lag, and shows a gradual upward trend in periods 1-4, with a maximum response value of 0.26. This paper provides a quantitative analysis of the effects of integrating aesthetic education and music and proposes a new direction for reforming the curriculum of the music major.

Authors: Liang Baoran , Liu Ruijuan 
Published: February 2024

Abstract
MA algorithms have received extensive attention from scholars soon after they were proposed, and are rapidly developing in various fields such as the problem of project schedule and the optimal allocation of cloud resources. In this paper, firstly, to address the lack of performance of the ordinary MA algorithm, Kent chaotic mapping is used in the initialization position to improve the initial traversal ability, and Sigmoid function is introduced to optimize the step-size settings in different stages of the crawling process. Different test functions are chosen to compare the efficiency of the solution and verify the performance of the improved MA algorithm. Finally, the improved MA algorithm is applied to allocate human resources in a city called China Mobile and a multi-project environment. Searching for the optimal solution and solving for the optimal value is the strongest performance of the improved MA algorithm compared to the other three algorithms. The human resource balance metrics of a city China Mobile are optimized and the peak human resource demand reaches the project below 120, reducing the waste of resources by about 20 people. In a multi-project environment, where 4 employees perform four different tasks, the optimal solution was found, resulting in an improvement in profitability.

Authors: Lu Biao 
Published: February 2024

Abstract
To do a good job of school ideological and political work and ideology work in the Internet era, it is especially important to integrate the organic integration of Civic and Political teaching and student management. This paper takes H city as an example and establishes an evaluation index system for student management and informationalization of ideological and political teaching. After normalizing and quantifying the indicators, the entropy weight method is used to solve the weights of the indicators, and the coupling coordination degree model is established to judge the integration level of the two informatizations. To investigate the integration factors of the two, the gray correlation coefficient and the degree of correlation between the indicators are derived using the gray correlation method. The results show that the average annual growth rate of the integrated development level between the two is 4.42% and 8.15% during 2011-2020, and the coupling degree is higher on the whole, with an average of 0.8994, and the coupling degree of coordination is also on the trend of increasing year by year. The gray correlation between the two is high, in which the correlation between the working mechanism of cooperative education in the informatization of the work of Civic Teaching and the quality of practice indicators and student management reaches 0.7806 and 0.7876. To diversify, it is necessary to develop the integration of student management and Civic Teaching based on the research in this paper.

Authors: Du Mingyin 
Published: February 2024

Abstract
Biomathematics is a cross-discipline formed by the interpenetration of mathematics with life sciences, biology, and other disciplines, and biomathematical models provide an effective tool for solving problems in the above application areas. Our aim in this paper is to combine mathematical analytical tools and numerical simulation methods to investigate the existence and steady state of periodic solutions in different nonlinear models. Time lags with both discrete and distributed characteristics are introduced into the Lotka-Volterra predator-feeder system, and based on the discussion of the central manifold theorem and canonical type theory, it is proved that the branching periodic solution exists when the discrete time lag parameter τ > τ
0. In the SEIRS infectious disease model with nonlinear incidence term and vertical transmission, the global stability of the disease-free equilibrium point and the local asymptotic stability of the endemic equilibrium point are analyzed through the computation and discussion of the fundamental regeneration number R
0 (p, q). A class of convergence-growth models with nonlinear sensitivity functions is studied, and the global boundedness of classical solutions and their conditions are demonstrated based on global dynamics. A mathematical generalization of the muscular vascular model is made by introducing a centralized parameter, the relationship between periodic solutions and chaotic phenomena is explored utilizing a systematic equivalence transformation, and the equation of the homoscedastic orbitals is deduced to be

Optimization of Teaching Innovation Path of Music Education in Colleges and Universities Based on the Stochastic Process Model
Authors: Liu Yu 
Published: February 2024

Abstract
In this paper, byte-pair coding is used to automatically learn the optimal combination between notes and chords, so that there are stronger dependencies between notes and chords in the sliced music blocks. Based on byte-pair coding to encode the information of the main melodic part of the original music, and after matrix transformation of the sample songs to obtain the note transfer probability matrix, the Markov chain in the stochastic process model is utilized to design an automatic music generation model. After preprocessing, experimental simulation is conducted in light of the flaws in music creation, and the music generated using the stochastic process model is examined following the pertinent evaluation indices. The findings suggest that the music generation technique suggested in this thesis is effective, as the UPC index value stays consistent between 3 and 5 throughout the training phase. Using stochastic process model-based music generation makes it easier for students to acquire music knowledge. This study has successfully aided in the development of music instruction in colleges and universities and has generated a more significant function in supporting the teaching of music education in these settings.

Authors: Luo Zhide 
Published: February 2024

Abstract
Eco-agricultural characteristic tourism is one of the important contents of China’s tourism research, and is also one of the important initiatives to solve the “three rural problems” and realize comprehensive well-off. This paper proposes a particle algorithm-optimized RBF neural network model based on a neural network, which greatly overcomes the defects of its busy convergence speed and complex learning and calculation process. This paper uses this neural network to analyze and summarize the existing historical data on ecological and agricultural characteristics of tourism management, and presents the current problems of agricultural characteristics of tourism management to the tourist site managers in the form of data, to develop the ecological and agricultural characteristics of tourism management mechanism. The analysis of data focuses on passenger flow management, human resource structure management, and tourist satisfaction management in tourism management. The data calculation indicates that the staff at the scenic spot has an inadequate educational degree and lacks strong professionalism. In this regard, the eco-agricultural tourism attractions make corrective measures, the proportion of employees with a bachelor’s degree and above is pulled to 39%, and the average value of tourists’ experience of the attraction reaches 0.737. The neural network model proposed in this paper can effectively analyze and summarize the data of the characteristic tourism management, and provide data support for the improvement and development of the eco-agricultural characteristics of the management of tourism.

Authors: Hu Dongming , Zheng Ying 
Published: February 2024

Abstract
In this paper, the fusion teaching model was constructed, and the clustering of music elements was statistically calculated by calculating the intra-class distance of music elements. The feature vector of big data clustering is extracted, the traditional music element data is partitioned using linear FM signal, and the spatial matrix of traditional music element data is obtained after initializing the clustering center. To form the information flow model of big data time series, the phase space reconstruction analysis method is used to process piano data in nonlinear mapping. To achieve the objective function after clustering, adjust the weights within the fitness function, and then output the optimal program of the integrated teaching model. The results show that the post-test scores of students in the experimental group are higher than those of students in the control group, and the scores of tuning and composition have been improved by 2 and 2.5 points to reach the full score of 10 compared with those of the control group, which demonstrates the validity and feasibility of the fusion teaching mode of traditional music elements and college piano.

A Comparative Study of PSO, GWO, and HOA Algorithms for Maximum Power Point Tracking in Partially Shaded Photovoltaic Systems
Authors: Berttahar Fares , Abdeddaim Sabrina , Betka Achour , Omar Charrouf 
Published: February 2024

Abstract
Solar energy harnessed through photovoltaic technology plays a crucial role in generating electrical energy. Maximising the power output of solar modules requires optimal solar radiation. However, challenges arise due to obstacles such as stationary objects, buildings, and sand-laden winds, resulting in multiple points of maximum power on the P–V curve. This problem requires the use of maximum power point tracking algorithms, especially in unstable climatic conditions and partial shading scenarios. In this study, we propose a comparative analysis of three MPPT methods: particle swarm optimisation (PSO), grey wolf optimisation (GWO) and Horse Herd Optimization Algorithm (HOA) under dynamic partial shading conditions. We evaluate the accuracy of these methods using Matlab / Simulink simulations. The results show that all three methods solve partial shading problems effectively and with high precision. Furthermore, the Horse Herd Optimization approach has superior tracking accuracy and faster convergence compared with the other proposed methods.

Authors: Buenfil Heredia Carmen Antonia , Vanega Romero Sally , Carrillo Trujillo Carlos David 
Published: February 2024

Se ha descrito la flexibilidad psicológica como uno de los factores protectores más importantes para la salud mental ante la pandemia de covid. El Cuestionario de Aceptación y Acción-II (AAQ-II) es el instrumento más ampliamente empleado en la evaluación de la flexibilidad psicológica y del proceso de cambio en las intervenciones para promoverla, principalmente la Terapia de Aceptación y Compromiso (ACT). Se han desarrollado numerosas adaptaciones y traducciones del instrumento a circunstancias clínicas y no clínicas particulares, pero no se tiene conocimiento de uno que explore específicamente la flexibilidad psicológica ante la pandemia de covid, debido a lo cual en el presente estudio se llevó a cabo la fase piloto del desarrollo del Cuestionario de Aceptación y Acción ante la Pandemia de Covid-19 (AAQ-COVID), un instrumento que valora el constructo unidimensional de flexibilidad psicológica, el cual consta de diez reactivos que se evalúan en una escala Likert de cinco opciones de respuesta. Empleando una muestra no clínica por conveniencia de 36 adultos en un rango de edad de 42 a 76 años, se concluye que tales reactivos tienen poder discriminatorio. Se discuten los cuidados metodológicos en el desarrollo y piloteo de los reactivos de instrumentos adaptados a contextos específicos.

Published: February 2024

Introducción: Los intentos de suicidio han aumentado entre la población joven, convirtiéndose ya en un problema de salud pública, y tienen importantes implicaciones individuales, familiares y sociales. El objetivo de este estudio fue establecer la relación entre ciertas variables culturales y el funcionamiento familiar en jóvenes con y sin intento de suicidio en Ecuador. Método e instrumentos: El presente fue un estudio de casos y controles. Se aplicó la Entrevista Neuropsiquiátrica Internacional para adolescentes y adultos, la Escala de Intención Suicida de Pierce, la Batería de Cuestionarios de Variables Multidimensionales Culturales, el FACE III y el FF-SIL, todos estos adaptados y validados culturalmente al contexto ecuatoriano. Para el análisis estadístico se realizó la prueba de comparación de medias entre dos grupos U de Mann-Whitney y el coeficiente de correlación rho de Spearman. Resultados: Se encontraron diferencias significativas en torno a la variable cultural independencia entre casos y controles (p > 0.05). En relación al funcionamiento familiar, los jóvenes que intentaron suicidarse pertenecían a familias disfuncionales. Discusión: Los patrones culturales influyen en el intento de suicidio en los jóvenes; sin embargo, el funcionamiento familiar, caracterizado por dificultades en la adaptación y una escasa cohesión, es un factor de riesgo para que se produzca la tentativa suicida.

Authors: Mendoza-Contreras Luis Alberto , Domínguez-Trejo Benjamín Domínguez-Trejo , Rodríguez-Medina David Alberto , Galindo-Vázquez Oscar 
Published: February 2024

El dolor es un importante problema de salud pública y uno de los síntomas más comunes en los pacientes con cáncer. Identificar los factores psicosociales relacionados con el dolor que genera esta enfermedad permitiría desarrollar tratamientos multidisciplinarios específicos con los que mitigar su impacto y así contribuir a mejorar la calidad de vida de los pacientes. Objetivo: Efectuar una búsqueda de la literatura de variables psicosociales relacionadas con dolor por cáncer. Método: Se llevó a cabo una búsqueda en las bases de datos Pubmed y PsycINFO de la literatura publicada entre los años 2016 y 2021 mediante la estrategia PICO. Resultados: Se revisaron en texto completo 22 estudios que cumplieron los criterios de inclusión. La intensidad de dolor es un predictor de calidad de vida y de sus diversas dimensiones y de la inferencia de dolor, esto es, grado en que interfiere con varios aspectos de la vida diaria. Los pacientes con síntomas de ansiedad y depresión tienen mayor probabilidad de sufrir una mayor intensidad del dolor, la que a su vez está relacionada con una salud autoevaluada más pobre, un menor apoyo social y un mayor sufrimiento y catastrofización del dolor. Conclusión: La identificación de las variables psicosociales asociadas con el dolor oncológico supone el establecimiento de objetivos de intervención para futuras investigaciones en el tratamiento no farmacológico para modular la percepción de dolor y mejorar la calidad de vida de los pacientes con cáncer en México.

Published: February 2024

Durante su educación universitaria, los estudiantes experimentan un nuevo entorno que implica adaptarse a las nuevas formas de relacionarse con sus familias y compañeros. Tal periodo se caracteriza por cambios en la edad adulta temprana que pueden afectar la salud mental. Debido a la reciente pandemia de covid-19, las actividades de los estudiantes se llevaron a cabo en un formato virtual. Considerando lo anterior, este estudio analiza la asociación de los indicadores de depresión y la conexión académica en estudiantes universitarios de la universidad pública de Guatemala. Se obtuvieron datos de 494 estudiantes de diferentes carreras. Para medir la conexión académica, los estudiantes completaron una adaptación de la subescala del instrumento What it is Happening in the School (WHITS), y para la depresión el cuestionario Patient Health Questionnaire (PHQ9), además de un cuestionario sociodemográfico. Se llevó a cabo una regresión lineal simple, siendo significativo el modelo (F [1, 49] = 79.10, p < .001, R² 13%), con una ecuación Y = β0 (17.53) + β1 (-0.32) X. Los resultados obtenidos demostraron una asociación negativa entre las variables estudiadas; es decir, que una mayor conexión académica se asocia a una disminución de los indicadores de depresión.
