The object of this study is a tractor with a front plow without a support wheel. One way to avoid the use of ballast is to use front-mounted plows that operate under the "push" mode. As a rule, such plows are equipped with at least one supporting wheel. The presence of the latter complicates the structure of the plow and, of course, affects the degree of vertical load on the steered wheels of the mobile vehicle.
With the help of the constructed mathematical model and the corresponding amplitude and phase frequency characteristics, the dynamics of vertical oscillations of the front axle of a tractor with a front mounted plow without a support wheel were investigated. Vertical fluctuations of the total force acting on the tractor from the side of the plow were considered as a disturbing influence. According to the simulation results, an increase in the vertical load of the front axle of the tractor by 600 kg causes a desired decrease in the value of the amplitude and an increase in the phase of external disturbances of the dynamic system. The higher the frequency of disturbance oscillations, the more acceptable these characteristics become. It was established that in order to improve the response of the studied dynamic system to disturbances, it is necessary to reduce the stiffness coefficient of the tires of the front wheels. In practice, this is achieved by adjusting the air pressure in the tires. The amplitude-frequency characteristics of the system almost do not change when the damping coefficient of the tires of the front wheels of the tractor is increased in the range from 1 to 3 kN·s/m, while the phase-frequency characteristics improve. This is especially noticeable at the frequencies of oscillations of the disturbing influence in the range of 0–10 s-1.
The results could be used as a basis for evaluating the efficiency of tractors with a front plow without a support wheel in tillage operations. Such efficiency can be achieved under the condition of practical implementation of the recommendations proposed in this paper regarding the selection of design parameters of tires for the front wheels of the tractor

This study aims to investigate the operation of a tractor as part of the tillage unit on the basis of analysis of its interaction with the supporting surface and the correlation between the mass of the tractor and tool. The classic approach to determining the efficiency factor does not take into account the extensive system of power take-off shafts and the extent of their use in combined tillage units. To solve the related problem, a mathematical apparatus was built in the study, which makes it possible to determine the rational ratio between the traction force of a tractor and the mass of the tillage unit.
Underlying the methodological basis of the work is the generalization and analysis of the study of traction indicators of the tractor as part of the tillage unit. Empirical models of unit operation were constructed by employing the basic principles of the system approach and analysis of technical systems. When improving the methodology of research using the method of partial accelerations and our devised procedures, it was possible to significantly reduce the time without compromising the quality of results. The maximum traction efficiency for John Deere 8R series tractors as part of the tillage unit was determined, ηTmax=0.719, as well as the conditions for its provision. The traction efficiency for tractors with wheel formula 4K2, mass Gim=6–10 t, with power consumption from 60 % to 80 % was determined; it is 0.58–0.64. The results of the study make it possible to obtain a new solution to the scientific problem of ensuring the maximum traction efficiency of the tractor as part of the tillage unit, based on the rational ratio between the traction force of the tractor and the weight of the machine-tractor unit. The proposed system approach could be used to justify the layout of units and recommendations regarding their modes of operation in the case of instability of operating mass and traction force

Objective: The objective of this research is to establish a relationship between the theory of multiple intelligences with the management and use of credit cards, including risk, patience, and economic education. This will allow the establishment of a line of marketing and consumption contextualized to the types of intelligence.
Method: The design is observational -correlational, and this analysis was done using structural equation modeling (SEM). There were 498 participants in the study.
Results: We found there was a positive relationship between the logical-mathematical and personal intelligences (intra and inter) with the management of patience, risk conditions, and tendency toward indebtedness. In the conceptual review, no studies were found that relate the present variables. In the same sense, the present work helps the marketing processes and product design better fit the profile of the user and/or buyer.
Conclusion: Finally, it sheds light on the construction of public policy for the management of marketing and financial education.

Introducción: El presente estudio revisa los postulados sobre la contribución de las relaciones infantiles de apego en el establecimiento de relaciones en la adultez. El objetivo fue explorar la asociación entre la percepción de los vínculos primarios establecidos con las figuras parentales y los estilos de apego adulto en jóvenes universitarios.
Método: Se realizó una investigación no experimental, cuantitativa, exploratoria y transversal. Participaron 247 estudiantes universitarios de Quito, 41,6 % de sexo masculino y 58,4 % de sexo femenino, entre 18 y 25 años de edad (M=20,75; DE=2,04). Se emplearon dos instrumentos validados en el Ecuador: la escala Parental Bonding Instrument (PBI) en sus versiones Madre y Padre y la escala Experiences in Close Relationships-Revised (ECR-R).
Resultados: Entre el ECR-R y el PBI se registraron correlaciones significativas únicamente en la versiónMadre: una inversa entre cuidado y evitación (r = -0,226; p < 0,001) y otra directa de sobreprotección con ansiedad (r = 0,203; p < 0,001) y con evitación (r = 0,147; p < 0,05). Se halló que la percepción del vínculo con las figuras parentales, especialmente con la madre, se asocia con los estilos de apego adulto (madre: r = 0,224, p < 0,001; padre: r = 0,136, p < 0,033).
Conclusión: El cuidado infantil contribuye al establecimiento de relaciones saludables en la adultez,no así la sobreprotección. La madre tiene un rol rotagónico en este aspecto, posiblemente debido a factores socio-culturales, por lo que es importante que la figura paterna asuma un rol más participativo.

Целью исследования является сравнительный анализ существующих теоретико-методологических подходов и парадигм социально-философского изучения ценностей как основы цивилизационного своеобразия обществ и в частности России.
Методологическую базу исследования составляют методы сравнительного анализа и метаметодологической рефлексии.
Результаты исследования. В условиях усложнения мировой обстановки и роста международной напряженности актуальным становится анализ особенностей и специфических характеристик цивилизаций. В свете этого большое значение приобретает поиск методологии, ориентированной на понимание цивилизационных различий в мировом пространстве. Обычно предпочтительным является обращение к цивилизационному подходу. Речь идет о необходимости цивилизационной рефлексии и укрепления национальной цивилизационной идентичности, что становится актуальным вызовом для общества. В построении основы цивилизации важную роль играют сакральные ценности, формирующие коллективную ментальность. Анализ цивилизационно-культурных ценностей в настоящее время требует использования широкого спектра теоретических подходов и парадигм, взаимодействующих для решения разнообразных исследовательских задач. Среди выделяемых автором наиболее значимых подходов и парадигм отмечается цивилизационный подход, дающий возможность исследования объективных факторов, таких как природные особенности, климатические условия, этногенез и другие предпосылки исторического развития цивилизационных особенностей: аксиологический подход, основывающийся на выделении и анализе базовых сакральных ценностей, принадлежащих культурному ядру цивилизации; социокультурный подход, ориентирующий на рассмотрение базовых ценностей цивилизации в контексте социокультурной динамики, глобального влияния и процесса глобализации в контексте анализа социокультурной триады, объединяющей социальные и культурные аспекты общества; подход, основанный на конструктивистской парадигме, для исследования процессов формирования и направленного конструирования цивилизационной идентичности как субъективного элемента цивилизации. Элементы различных подходов, несмотря на их различия, оказываются совместимыми и необходимы в силу сложности цивилизационной проблематики, которая не поддается редукции.

An labeling of a graph is a function f from the set of vertex V(G) to the set of positive integers for any two vertices u, v where label difference |f(u)-f(v)|≥3 for distance d(u,v)=1 and label difference |f(u)-f(v)|≥1 for distance d(u,v)=2. In this study, the smallest positive integer λ where the maximum label used on L(3,1)-labeling for supercycle graph Sc(n,r) was formulated. The supercycle graph Sc(n,r) is the result of combining two special graphs, namely cycle graph Cn and Hanoi graph Hr. To determine the formula for the minimum span value of labeling on supercycle graph, a pattern detection method is used, which is labeling several supercycle graph with certain n and r values, then we generalized. We obtained that λ(Sc(n,1))=6 if n= 1. Furthermore, λ(Sc(n,1))=7 if n1 and even; λ(Sc(n,1))=8 if n1 and odd. In addition, λ(Sc(n,r))=8, for r1.Keywords: L(3,1)-Labeling, Supercycle Graphs.

Abstract

Introduction: Autism Spectrum Disorder (ASD) is a complex neurodevelopmental disorder that is increasing in prevalence globally. There is an emerging field of research investigating the association between head circumference and ASD but there is a marked paucity of such data from Southern Africa.

Aim: To describe the head circumference (HC) measurement of children diagnosed with ASD and to investigate associations between HC, ASD severity levels and associated comorbidities.

Methods: A retrospective record review of children diagnosed with ASD attending a neurodevelopmental clinic at a large public hospital in South Africa was conducted. Demographic data and HC measurements from the first clinic visit were collected. The World Health Organization data set of head circumference norms were used as the comparator reference population. Statistical analysis was conducted using parametric, descriptive and inferential methods.

Results: Data from 135 children diagnosed with ASD were included. The sample population had a mean age of 43 months (range 13-61 months) and 107 (79%) were males. Thirty (22.2%) patients in the cohort had a HC which was classified as macrocephalic. Almost half (46.7%) had an ASD severity level of three and 94 (69.6%), had been diagnosed with a comorbidity. In this study no significant association was found between macrocephaly and ASD severity.

Conclusions: Measuring the HC during childhood is a cost-effective, simple and non-invasive procedure that may well assist professionals in raising suspicion of ASD at an early age. Early detection and intervention could optimise participation and integration for the individual living with this life-long neurodevelopmental disability.

Published: March 2024

Background: The publicly available large dataset plays an important role in the development of the natural language processing/computational linguistic research field. However, up to now, there are only a few large Indonesian language datasets accessible for research purposes, including sentiment analysis datasets, where sentiment analysis is considered the most popular task.
Objective: The objective of this work is to present sentiment analysis on a large Indonesian product review dataset, employing various features and methods. Two tasks have been implemented: classifying reviews into three classes (positive, negative, neutral), and predicting ratings.
Methods: Sentiment analysis was conducted on the FDReview dataset, comprising over 700,000 reviews. The analysis treated sentiment as a classification problem, employing the following methods: Multinomial Naïve Bayes (MNB), Support Vector Machine (SVM), LSTM, and BiLSTM.
Result: The experimental results indicate that in the comparison of performance using conventional methods, MNB outperformed SVM in rating prediction, whereas SVM exhibited better performance in the review classification task. Additionally, the results demonstrate that the BiLSTM method outperformed all other methods in both tasks. Furthermore, this study includes experiments conducted on balanced and unbalanced small-sized sample datasets.
Conclusion: Analysis of the experimental results revealed that the deep learning-based method performed better only in the large dataset setting. Results from the small balanced dataset indicate that conventional machine learning methods exhibit competitive performance compared to deep learning approaches.
