The Spatiality of the Body in Football
Authors: Nunes Nuno André , Petiot Grégory Hallé , Adeosun Kola
Published: March 2024

This research aims to address the critical issue of how the spatiality of the body intersects with football philosophy, with a specific focus on the context of training and match strategies. Traditionally, in football, coaching factors emerge within the training environment and are closely aligned with the intended game model. However, isolating these factors from the broader game model risks decontextualizing them, potentially undermining crucial aspects such as solidarity, team spirit, motivation, discipline, and rigor. Moreover, there is a pressing need to ensure that physical, technical, and psychological aspects are subordinated to tactical thinking and a relentless pursuit of victory during training sessions. This imposes a mindset of seriousness and rigor to effectively navigate the demands of complexity inherent in collective play. Drawing insights from philosophical discussions by Merleau-Ponty and Edgar Morin, as well as contributions from Manuel Sérgio and other scholars, this research seeks to deepen our understanding of the intricate relationships between players within a team. By exploring these dynamics, the study aims to shed light on how interactions among players shape team dynamics and influence individual players’ perceptions within the broader coaching context. Ultimately, the paper endeavours to contribute to a nuanced comprehension of the spatial and philosophical dimensions inherent in football training processes, thus offering valuable insights for both researchers and practitioners in the field.

Natural law and the rights of nature – in search of more effective environmental protection
Authors: Kowalska Samanta
Published: March 2024

The paper discusses innovative legal regulations that may contribute to increasing standards ofenvironmental protection. In the face of increasing nature degradation and climate change, current protection measures are insufficient. The dysfunction of the political system, international institutionalisation, and existing legal regulations, result in the strengthening of the global economy instead of increasing the extent of activities aimedattheprotection of nature. It is argued that the concept of natural law, which focuses on the protection of human rights, is not the same as the rights of nature. However, the analysis of the origins and axiological and legal assumptions of boththese concepts allows us to formulate the conclusion that both can form a common ethical perspective needed in order to protect the community of life on Earth. The aim of the considerations is to discuss the concept of the rights of nature, which are the basis for shaping the new environmental ethics. Appealing to common axioms, the idea of the rights of nature favours overcoming the limitations resulting from property law and the currently dominant economic and utilitarian factors. The paper arguesthat the environmentally-profiled rights of nature can become an ally in environmental protection.

Variational multiscale stabilized FEM for cardiovascular flows in complex arterial vessels under magnetic forces
Authors: Sahoo Dipak Kumar , Rathi Anil , Kumar B. V. Rathish
Published: March 2024

In this study, we present a variational multiscale stabilized finite element method for steady-state incompressible fluid flow under magnetic forces. In particular, an algebraic approach of approximating the subscales has been considered, and then, the stabilization parameters are derived using Fourier analysis. The proposed scheme is used to trace the blood flow dynamics in complex arterial vessels under multiple pathological conditions. We examine the pressure and stress distribution in addition to the flow pattern to assess the criticality of the diseased condition.
Assessing the impact of information-induced self-protection on Zika transmission: A mathematical modeling approach
Authors: Manisha  , Nidhi  , Kumar Anuj
Published: March 2024

As per the World Health Organization’s (WHO’s) suggestions, personal protection via adopting precautionary measures is one of the most effective control aspects to avoid Zika infection in the absence of suitable medical treatment. This personal protection further can be enhanced and explored by propagating information about disease prevalence. Therefore, in this study, we wish to see the effect of information on Zika transmission by formulating a compartmental mathematical model that quantifies the effect of an individual’s behavioral response as self-protection due to information. Furthermore, the basic reproduction number was calculated using the next-generation matrix technique. The model analysis was carried out to determine the local and global stability properties of equilibrium points. In addition, the model shows the occurrence of forward bifurcation when the reproduction number crosses unity. To understand the impact of various model parameters, we conducted a sensitivity analysis using both the normalized sensitivity index and the partial rank correlation coefficient methods. Moreover, we performed numerical simulations to assess the influence of important parameters on the model’s behavior for Zika prevalence. Our study accentuates that as information-induced self-protection increases, the prevalence of Zika infection will be at a very minimum level, and this observation is in line with WHO suggestions.

Authors: Yousif Maysam Ali , Zghair Hussein H. , Alsaeedi Firas
Published: March 2024

To sustain the life of flexible pavement materials, the quality of the binder needs to be modified and improved. The purpose of the current research is to investigate the optimum mechanical performances, Marshall characteristics, and moisture damages of hot asphalt mixtures containing nano-clay (nC) additives. Three nominated contents of nC additives of 3, 5, and 7% of the hot asphalt weight were combined by a shear blender at 4,000 rpm for 45 min at 150 ± 5°C. Significant mechanical tests were carried out to estimate the modified asphalt mixture characteristics, such as Marshall stability and moisture susceptibility. Mechanical test results showed that the use of nC as an additive was suitable for enhancing the main characteristics of hot asphalt mixes. Generally, it was found that the indirect tensile strength ratio and stability values of the asphalt mixtures containing 3, 5, and 7% of nC were improved by 8, 23, and 24% and 12.5, 40, and 52%, respectively. The 7% nano-clay additive showed superior values of tensile strength and stability as compared with all asphalt mixtures (i.e., 94% and 15.8 kN, respectively).
Examination of archaeological bronze parts using micro-computed tomography and metallography
Authors: Haubner R. , Strobl S.
Published: March 2024

Archeological finds, such as old coins among which some show signs of corrosion, are, in general, unique pieces even though several copies exist of individual types. Subferrati, Roman coins with an iron core and a bronze coating, for instance, could be examined by conventional computed tomography (CT). The CT image allows an easy distinction of corrosion products, metallic iron, and the bronze so that appropriate sections could be selected from the images for metallography.

The micro-CT technology even allows examining smaller archaeological objects to get an overview. The resolution of the micro-CT is a function of the object size and lies between 5 and 10 μm. The following metallographic examinations are intended to characterize the microstructure. Apart from these examinations, SEM analyses may also be performed on the sections.

Different bronze pieces from cremation and inhumation burials were examined. Micro-CT provides a well recognizable contrast between corrosion products and the metallic bronze.

If several similar objects exist, micro-CT examinations allow a decision to be made on which parts are suitable for metallographic analyses and which are not.
AI recommendations’ impact on individual and social practices of Generation Z on social media: a comparative analysis between Estonia, Italy, and the Netherlands
Authors: Arkhipova Daria , Janssen Marijn
Published: March 2024

Social media (SM) influence young adults’ communication practices. Artificial Intelligence (AI) is increasingly used for making recommendations on SM. Yet, its effects on different generations of SM users are unknown. SM can use AI recommendations to sort texts and prioritize them, shaping users’ online and offline experiences. Current literature primarily addresses technological or human-user perspectives, overlooking cognitive perspectives. This research aims to propose methods for mapping users’ interactions with AI recommendations (AiRS) and analyzes how embodied interactions mediated by a digital agent can lead to changes in social and cultural practices. For this, this work proposes a comparative analysis of central practices evoked by AI recommendations-mediated communication on SM among users in Italy, Estonia, and the Netherlands in the age category 18–26 years old. The data used in the comparative analysis was collected via semi-structured interviews and elaborated based on cognitive psychology and semiotics. This research highlights the contextual significance of AI recommendations as a mediator in creating new communication practices. Findings confirm that young adults often choose practices that would enhance their digital representations according to AiRS’ dominant patterns and categories. AiRS impacts individual interpretations and practices and can further affect social and cultural levels.
Lubrication Performance of Compound Microtexture Friction Pairs
Authors: Wang Lili , Liu Ying’ao , Zhang Wei , Bao Yunlong
Published: March 2024

To improve the lubrication performance of friction pairs to the greatest extent and obtain the best microtexture, a new compound microtexture with multiple shapes is proposed, and the influence of compound texture arrangement on the lubrication performance of friction pairs is studied. Based on the Reynolds equation, a numerical calculation model of compound microtexture friction pairs under the condition of hydrodynamic lubrication is established, and equations are solved using the finite difference method. Considering the influence of surrounding texture and cavitation effect, the influence of compound texture arrangement and shape on the lubrication performance of friction pair is studied. The results show that compared with the single microtexture, the compound texture with two different shapes can influence each other during the lubrication process, which can better improve the average pressure in the microtexture region, reduce the friction coefficient, and obtain the stronger hydrodynamic effect and better lubrication performance. The circumferential parallel arrangement of compound microtexture can produce the stronger hydrodynamic effect and improve the performance of the friction pair.
CHARACTERIZATION AND APPLICATION OF WHEY PROTEIN ISOLATE BASED EDIBLE FILMS CONTAINING CLOVE AND APRICOT ESSENTIAL OILS
Authors: Erdem Yeşil Işık , Kaya Sevim , Gökkaya Erdem Burcu
Published: March 2024

The aim of this research is to investigate the effects of essential oils on the mechanical and antimicrobial properties of protein-based edible films. Clove and apricot oils were added to whey protein isolate (WPI) solutions and were named C-WPI and A-WPI, respectively. Kaşar cheese was chosen as a food sample to investigate the behavior of modified films on a food product. It was observed that the oil-protein interaction increased the elasticity but decreased the strength of the emulsified films. The incorporation of oil into the film matrix resulted in a more opaque appearance but also increased thermal stability. It was detected that both types of essential oils impart antimicrobial properties of the films, but clove oil is more effective than apricot oil. In conclusion, the successful antimicrobial properties of the modified WPI film make it a potential packaging material, especially for food products prone to microbiological spoilage.

Published: March 2024

The efforts to build character and control student behavior are executed through the learning process and the application of school rules. Although learning activities and enforcing rules have been well pursued, in reality there are still many behavioral deviations committed by students. The research objectives are to identify forms of deviant behavior by students, analyze the factors that cause students to engage in deviant behavior and identify the types of parenting styles of students as well as school efforts in tackling students' deviant behavior. The data analysis technique used is qualitative data analysis with Merton's structural functional theory. Data collection is done by observation, in-depth interviews and documentation studies. The results showed that there were deviant behaviors executed by students of SMP Nusa Bhakti are smoking, drinking alcohol, and drug abuse. This deviant behavior is caused by the imperfect socialization process and the result of the socialization process of deviant sub-cultural values. The imperfect socialization process is influenced by students' family environmental factors, while the results of the socialization process of deviant sub-cultural values are influenced by environmental factors of peers, schools, communities and mass media. The efforts to overcome deviant behavior are executed by preventive, repressive, and curative methods.

Published: March 2024

Currently, many students attend residential schools, private institutions, and public schools. Many students board during the day while attending Junior High School Teachers' Association of the Republic of Indonesia (SMP PGRI) Brebes from the morning till lunchtime. The purpose of this study is to identify and evaluate the contribution that schools and boarding schools make to students' assimilation of school culture and their religious character (SMP PGRI Brebes). It is a qualitative sort of study. Students, teachers, school administrators, and leaders served as study informants. In-depth interviews and documentation were employed for data collection in this study. Data collection, data reduction, data display, and conclusion retrieval are used in data analysis. The habituation and application of religious principles in the classroom and in society are the functions of schools in the establishment of religious culture in schools. The religious character traits that SMP PGRI Brebes kids can exhibit include, among others, helpful character, discipline character, courtesy character, and justice character. Students who receive support from boarding schools and from schools that instill boarding school culture show signs of internalizing religious culture in their behavior. This study is anticipated to serve as a source of information for school-based character education.
Integrating Population Education in Sekolah Siaga Kependudukan (SSK) in Building a Planned Generation
Authors: Septiani Endah , Setyowati Dewi Liesnoor , Atmaja Hamdan Tri
Published: March 2024

To solve increasing population in Indonesia, population education can be implemented in school. The purpose of this study was to analyze the integration of population education in SSK as an effort to realize a planned generation. A phenomenological design with an interview, observation, and documentation was employed in this research. The study's results showed that the integration process of population education in secondary schools occurred through teaching and learning and extracurricular activities, school programs, and pojok kependudukan (population corner). The integration of population education in SSK is inseparable from adaptation, goal attainment, integration, and latency, creating a substantial value and resilience system. The novelty of the research lies in the analysis of Talcott Parsons' structural-functional theory to integrate SSK for the Planned Generation with an adaptation process, where students learn about various population issues. The integration of multiple parties raises students' self-awareness to reach marriage-age maturity, avoiding premarital sex, and sustainably maintain their reproductive health. However, the iintegration requires a more effective delivery medium for the current generation. Therefore, it is necessary to use technology-based population education media that students can utilize. Meanwhile, for science, population-based technology can also be an innovation in streamlining the integration process of population education.

Tobacco Marketing Conflict between Farmers and Middlemen in Palongan Village, Bluto District, Sumenep Regency
Authors: Shadiqin Bani , D. W. P. Sucihatiningsih , Rachman Maman
Published: March 2024

The existence of tobacco is intended to meet the demand for cigarette factories. The indirect marketing chain is the cause of the price game by stakeholders. This situation has led to a loss of trust in trading partners, farmers suspect that there is a selling price game being played by middlemen and warehouses. The price game creates negative prejudice to stakeholders. The aim of this research is to analyze conflicts between farmers and stakeholders and solutions for farmers to the problems that occur. This research uses a qualitative method with a phenomenological approach. Data collection was carried out by observation, interviews, and document study from related research. The results show that determining the category of tobacco can certainly trigger conflict between farmers, bandol, and factory warehouses because it affects general selling price indicators in the market. Farmers' expectations of selling prices and intimidation by bandol elements give rise to conflicting opinions about the two, thus triggering conflict. The uncertainty of tobacco prices has made some farmers use an alternative substitute for this commodity by cultivating corn.

Abstract. Kindergarten-aged children are going through an important period of cognitive development, such as the ability to think concretely, including recognizing simple geometric shapes such as circles, triangles, and squares. However, many children find it difficult to understand the basic concepts of two-dimensional shapes.Purpose: It is necessary to develop prototype learning aids in the form of intelligent systems in two-dimensional shapes applications for kindergarten students, which utilize information technology and object visualization directly through cameras on smartphones. This is expected to increase children's learning motivation and help strengthen their understanding of two-dimensional shapes.Methods: The research combines Waterfall and Agile methodologies, tailoring them to four stages: plan and discovery, analysis and design, application development, and testing. Testing gathers accuracy with 120 smartphone-collected data points for square, triangle, circle, and pentagon shapes. Also, usability testing based on learnability, efficiency, memorability, error handling, and satisfaction, was obtained from six kindergarten teacher questionnaires and quantitatively processed.Results: The application achieves an accuracy rate of approximately 79%. Notably, accuracy decreases with fewer corners, mainly due to low resolution or lack of focus, resulting in simplified detected shapes. Regarding usability, it is evident that the application has received positive feedback from users, particularly kindergarten teachers, who have given it an average score of 78.83.Novelty: Distinguished from previous research, the novelty of this study resides in its ability to capture objects through a camera, eliminating the need for predefined shapes within the application, and innovating by creating an educational tool aligned with the kindergarten curriculum to recognize two-dimensional shapes. The research contribution is the creation of an innovative learning tool for kindergarteners, merging smartphone technology with real-world objects to teach two-dimensional shapes, thus integrating technology into early childhood education effectively, which has urgency in efforts to improve the quality of learning.
