<p>The core elements of a language are its vocabulary. Early childhood development is a critical time in a person's life that holds great significance for their future. There are problems that young learners face in learning language such as hard to get focused, easy to feel bored, struggle to remember or recall vocabulary items, and still need a stimulus to boost their motivation in the learning process. Learning vocabulary through songs and video making are one of the ways to solve those problems. This current study aims to examine if the songs help young learners in retaining English vocabulary and whether a video making is effective in engaging them in learning vocabulary. This current study used a content analysis design and the samples were 5 students who are 3-7 years old and enrolled English class at RainbowKids BPI.

Published: January 2025

The large number of victims of road traffic accidents around the world creates a serious problem for the economy, demography, and health care. The value of global social risk calculated according via relevant method, is within 18, in Russia it is of 9,7. Statistical data shows that government activities in the Russian Federation to improve road traffic safety are effective. Over the past ten years, the core values of road traffic accident rate have been decreasing, despite the increasing level of motorisation. Federal regulations stipulate a further decrease of target social risk index by 2030 to the value of 4.Excessive speed and inconformity of the speed with specific traffic conditions are the most common cause of road traffic accidents (19 % of the total). The ideas of many urbanists (that often are not backed up by specialised research in the field of road traffic safety) to forcibly make abandon cars and reduce speed in cities cannot be implemented to full extent, although they have local positive results.The likelihood of occurrence of a road traffic accident is significantly influenced by the individual characteristics of drivers, such as age, gender, and general risk propensity. One of the factors causing road traffic accidents, especially by young drivers, is the presence of peers. They can be the cause of dangerous driving, inattention, and the driver’s desire to «show off.» Older drivers, on the contrary, become more attentive and careful in the presence of passengers. However, in the scientific literature contains also opposite results (passengers can have a positive effect on young drivers, but a negative effect on older ones).In this regard and in the context of developing recommendations on reduction of road traffic accident rate, it is relevant to study feasibility to set some restrictions for younger drivers. The objective of the work is to evaluate the influence of a passenger of the same age on driving speed for a young driver and to compare it with the influence of a passenger on an older driver. The research method was an experiment in which young drivers aged 18 to 25 years and more experienced drivers over 35 years old drove along a set route with and without a passenger, while the speed of a car was recorded. An increase in speed was revealed when most young drivers were driving with a peer passenger. Considering that most young people overestimate their ability to drive a car, violation of the speed limit under the influence of a passenger can affect the occurrence of a road traffic accident. Based on the results of the work, it is proposed to introduce a system of phased access to driving, introduce a ban on transportation of passengers until the drivers reach a certain age or gain relevant experience, and improve drivers’ training programs.

Published: January 2025

In a harmonious transport system, traffic flows are rationally distributed depending on the capacity of roads and streets to ensure transit capacity, considering the traffic light control systems. At the same time, due attention is not paid to changes in weather and natural conditions, which in turn significantly adjusts driving regimes, taking them out of a stable, predictable state. Modern software and hardware systems and information resources of large cities have a wide range of recorded indicators that affect distribution of traffic flows. Their automated processing using algorithmic machine learning tools has formed a comprehensive understanding of the patterns of change in the traffic intensity indicator, which is a new stage of improving road traffic safety, striving for zero mortality.The scientific novelty of the study refers to the techniques and approaches to studying the weather and climate characteristics and factors of the street-and-road network, their preliminary processing using modern statistical and logical methods of normalisation and eliminating random outliers.The deep learning method opens wide opportunities for analysing the intensity of the road traffic flow. By processing large amounts of data, such algorithms are able to identify complex patterns and relationships, which improves traffic forecasting and optimises traffic management. For correct operation of the neural network for training the model and studying the road traffic flow intensity, a set of software tools for preliminary data processing has been developed, which includes a step-by-step analysis of array structures with subsequent replacement of values or elimination of errors.Preliminary data cleaning in accordance with the syntax of the program logic and the rules of statistical analysis is followed by application of a method for searching and eliminating anomalies was used, i.e. the isolation forest method.This research direction was part of a large study on road traffic flow intensity, and the described results are a set of solutions based on the system interaction of software and methods of statistical and analytical transformations developed by the authors.

Published: January 2025

The article considers the efficiency of providing priority conditions for urban passenger transport by allocating separate lanes for public transport on the roadway. The results of modelling the traffic flow on the considered segments of the city street network are complemented by a conclusion about the need to improve road traffic management on these segments, considering the intensity and composition of the traffic flow.Simulation allows creating mathematical or computer models for analysing and assessing the traffic conditions of urban passenger transport. The models are based on various parameters of traffic flows, the schedule of urban passenger transport, the location of public transport stops, etc. Modelling allows conduct of different experiments to assess the effectiveness of various measures and changes in the transport system.The objective of the study is to develop a methodology for analysing traffic conditions that will identify and assign priority to urban passenger transport traffic to achieve efficiency and comfort of its operation, improve transport accessibility and reduce traffic delays.Optimisation of the traffic provides for various management scenarios to find optimal solutions that reduce delays, congestion, traffic intensity, etc.Route planning is necessary for developing an optimal strategy for efficient passenger service. Demand forecasts make it possible to predict not only passenger traffic, but also the need for transportation in different periods, which is necessary for route planning and selection of optimal rolling stock features. All these areas of modelling the urban passenger transport traffic are developed to achieve the goals of increasing efficiency, reducing the risk of road traffic accidents, improving the quality of transport services and the safety of passenger transportation, which should create a sustainable system aimed at satisfying the basic needs of urban transport passengers.
A New Approach to Determining Road Capacity
Authors: Tolkov A. V. 
Published: January 2025

The objective of the study is to analyse capacity of a road which depends on many factors. The formula underlying the regulatory methodology for determining capacity relates the actual capacity to the maximum capacity through the final capacity reduction coefficient, consisting of the product of seventeen partial coefficients.According to this methodology, it is recommended to use no more than six partial coefficients in calculations while defining a set of these partial coefficients for each specific case. And this is where the problem of choosing the most significant partial coefficients arises.One of the central streets of the city of Vladimir, Gorky Street, was chosen as the object of study.The objective was achieved with the observation method and experimental studies of intensity of vehicle traffic on the considered street.Several cross-sections were selected along the length of the street for measuring traffic intensity and composition of traffic flow during rush hour. The parameter being determined is the final coefficient of reduction in road capacity. It was calculated for each lane in the cross-section area. Then, its values were averaged over even and odd sides of the street, as well as along the length of the entire street.This work uses, as an example, due to the small number of cross-sections, geometric interpolation with a Lagrange polynomial. Next, the maximum interpolation error was determined, and graphs were drawn of the dependences of the experimental and interpolated curves of the final coefficient of reduction in road capacity for even and odd sides of the street, as well as along the length of the entire street. For practical purposes, it is necessary to choose an interpolation method that will provide the minimum error. Thus, having a mathematically described curve, it is possible to determine the value of the final capacity reduction coefficient for any cross-section of the street.The work has resulted in development of a methodology for experimental determination of road capacity, which allows one to determine the final capacity reduction coefficient for a specific, already existing road.

Published: January 2025

White maize is a staple food for Andean populations in Ecuador, particularly in rural and impoverished areas. This study aimed to assess the potential impact of mycorrhizae fungi and nitrogen fertilization on the growth and yield of white maize in the Andean conditions of Loja, Ecuador. The field trial was conducted in Loja, Ecuador, using a completely randomized design arranged in a bifactorial scheme. The first factor involved the mycorrhizae inoculation, comprising three doses: 0 (control), 330 and 660 spores per plant of the mycorrhizal fungi. The second factor focused on nitrogen fertilizer, with three doses: 0 (control), 40 and 80 kg ha-1 of nitrogen applied throughout the crop cycle. The combination of mycorrhizal inoculation and nitrogen fertilization promoted plant height and stem diameter: the best results were attained when applying 330 spores per plant of mycorrhizae and 80 kg ha-1 of nitrogen. Independent nitrogen and mycorrhizal application significantly increased the cob number per plant, grain weight and yield, reaching a maximum of 9.9 t ha-1. Notably, mycorrhizae inoculation significantly increased grain nitrogen content by 7 % compared to the control, which suggests its potential to enhance the dietary quality and food security of the Andean population.
