Thanks to its carbon-free nature, it is possible to say that hydrogen is a potential fuel for future automotive systems. Its main favourable properties include high burning rate, wide range of flammability and low ignition energy. In combination with hybrid electric technology, the hydrogen combustion engine has the potential for further development with the goal of maximum efficiency in energy conversion. For more efficient hydrogen combustion, a dual fuel injection hybrid system is designed, where one injector is designed for direct hydrogen injection into the engine cylinder and the other injector is supply fuel to the engine's intake pipe. The greatest challenge is development of a control algorithm intended for management of the combustion process in hydrogen engine and optimization of fuel injection divided into individual doses.

Auxilio Social. Un espacio de trasmisión intergeneracional del compromiso político durante la inmediata posguerra
Authors: Díaz Sánchez Miguel
Published: December 2024

Este artículo analiza los compromisos políticos desplegados por algunas mujeres dentro de Auxilio Social, principal institución asistencial del régimen franquista durante la inmediata posguerra. Nos centraremos, concretamente, en los espacios de control que dicha institución articuló en torno a la infancia y a las mujeres cumplidoras del Servicio Social de la Mujer. También tomaremos como objeto de estudio a una mujer que ejerció responsabilidades de mando en la institución: Josefina Sánchez Pedreño, primera delegada provincial de Auxilio Social en la provincia de Murcia. Respecto al primer caso, analizaremos los comedores infantiles instalados en la periferia urbana de la ciudad de Madrid. Veremos cómo dichos espacios
fueron proclives para la trasmisión intergeneracional de las diferentes culturas políticas que conformaron la coalición republicana en la Guerra Civil, al menos, durante los primeros resortes de la posguerra; respecto al segundo caso, tomaremos como referencia el recorrido biográfico y político de Josefina Sánchez Pedreño. Definiremos su compromiso político en la Murcia de los años treinta, el cual derivó desde posiciones progresistas a posicionamientos fascistas, para así constatar que las posibilidades de trasmisión intergeneracional de los compromisos políticos estuvieron sujetas a las dinámicas de género imperantes en cada cultura política.

Authors: Kaur Amreen , Duncan Meagan , Takeda Mami , Singh Bhupinder
Published: December 2024

Purpose of the study: The study aimed to assess maturity offset in overweight children nearing adolescence and investigate potential differences in peak height velocity and fitness levels within this population.

Methodology: The study involved 28 individuals (14 boys and 14 girls) aged 8-11 years with a body mass index >85th percentile. Maturity offset, peak height velocity, and cardiovascular fitness were measured for all subjects.

Results: The study revealed that the average age of peak height velocity for girls was 10.69 ± 2.51 years, while for boys it was 13.40 ± 2.29 years. Differences were observed in age of peak height velocity, maturity offset, leg length, and cardiorespiratory fitness, with girls having higher means for the maturity offset and leg length and boys having higher means for peak height velocity and cardiorespiratory fitness.

Conclusions: In late childhood, boys with an elevated body mass index have higher cardiorespiratory fitness as compared to girls. Girls who are overweight tend to reach maturity earlier than boys with a similar body mass index. Additionally, girls experience an early growth spurt in terms of height compared to boys, although boys demonstrate a superior overall peak height gain compared to girls.

PREPARATION OF CONDUCTIVE MEMBRANES BY CHEMICAL IN SITU POLYMERIZATION OF POLYPYRROLE ON CELLULOSE FIBERS
Authors: Duc Dong Tran , Duc Tung Dao , Hoang Van Bui , Dinh Quang Nguyen , Dinh Tu Bui , Thi Thao Vu , Duc Cuong Nguyen
Published: December 2024

The development of flexible electronic devices, particularly flexible and bendable energy storage devices, has catalyzed significant interest in the research of flexible composite materials. In this study, conductive paper membranes were synthesized by polymerizing polypyrrole (PPy) on the surface of cellulose fibers. The cellulose material, derived from cardboard, underscores an eco-friendly approach to waste reduction and environmental protection. Characterization of the cellulose/PPy conductive membranes using Fourier-transform infrared spectroscopy (FT-IR), field-emission scanning electron microscopy (FE-SEM), and differential scanning calorimetry (DSC) confirmed the formation and uniform coverage of PPy on the cellulose surface. To enhance the uniformity of PPy polymerization on cellulose relative to previous studies, this work focuses on elucidating the formation and deposition of PPy particles on cellulose fibers, leading to the development of a homogeneous membrane. The membrane exhibited a peak electrical conductivity of 18.04 mS/cm at 0.1 mA, with conductivity increasing alongside PPy concentration, albeit at the expense of mechanical properties. Additionally, the membrane demonstrated charge storage capability, with specific capacitance values ranging from 22.5 to 50 pF/cm2 at a frequency of 1 kHz. The uniformity of PPy coverage on the cellulose surface was a crucial factor influencing the electrical properties of the composite membrane. This research highlights the significant potential of conductive membranes for application in flexible and bendable energy storage devices.

Published: December 2024

SABATH is one class of enzyme belonging to the class of methyltransferase, playing a crucial role in plant defense and stress response mechanisms. Despite its importance, no systematic analysis of the expansion of the SABATH gene family in cassava (Manihot esculenta) has been reported up to date. In this study, we investigated the SABATH gene family in cassava, revealing their random distribution across 18 chromosomes, with variable numbers of gene copies per chromosome. According to gene duplication analysis, five duplication events were identified, primarily segmental duplications, indicating their evolutionary significance. The Ka/Ks ratio analysis indicated that most duplicated genes are under negative selection, preserving their functions, while one pair showed signs of positive selection, suggesting adaptive benefits. Gene structure analysis showed diverse exon counts, primarily three or four. Expression profiling across 11 cassava tissues demonstrated tissue-specific expression patterns, with some genes highly or exclusively expressed in specific tissues such as root apical meristems, embryogenic calli, and fibrous roots, implying distinct functional roles in cassava growth and development. Overall, this study provides valuable insights into the evolution and functional diversity of the SABATH gene family in cassava and identifies candidate genes for further functional characterization.

Authors:   The Korea Association of Yeolin Education, Hwang Sungwon , Lee Hyunjoo
Published: December 2024

This study qualitatively analyzes the self-report of 22 Generation Z pre-service early childhood teachers attending a four-year university, in anticipation of the imminent implementation of the policy integrating early childhood care and education systems. The self-reports consist of freely written reflections on various topics, including the reasons for aspiring to become an early childhood teacher, the background of their family environment, their innate dispositions, personal experiences related to their career path, their self-assessment of whether they possess the qualities and competencies required as early childhood teachers, and in what aspects they see themselves as suitable or lacking for the role.The total text amounted to 48 pages, and a continuous comparative analysis method was applied through the coding process. The qualitative content analysis resulted in the identification of three key concepts: developmental and environmental characteristics, personal characteristics, and relational characteristics, which were further categorized into seven main themes. The developmental and environmental characteristics included motivations for choosing a career in early childhood education. The personal characteristics encompassed self-management, the thoughts and attitudes of early childhood teachers, and efforts to improve oneself in preparation for the role. The relational characteristics were categorized as empathy and consideration, cooperation and support, and the demand for professionalism among early childhood teachers. An understanding and analysis of Generation Z pre-service early childhood teachers can provide valuable reference material when restructuring teacher education or teacher personality development courses in early childhood education departments, particularly after the integration of early childhood education and care systems.

Authors: Vinacur Tamara , Kelly Valeria , Sanchez Yamila , Steinberg Cora
Published: December 2024

El presente documento examina la integración de tecnologías digitales en la educación inicial en Argentina, haciendo foco en la alfabetización temprana. Esta última, entendida como la adquisición de la lengua escrita desde la primera infancia, se caracteriza por empezar antes de que el niño o la niña domine las habilidades técnicas que implican la lectura y la escritura, y es clave para su desarrollo educativo. En este contexto, las tecnologías digitales ofrecen una oportunidad para enriquecer este proceso, particularmente en un momento en el que la calidad educativa en Argentina enfrenta importantes desafíos, según las últimas evaluaciones estandarizadas para América Latina y el Caribe (ERCE). En 2016, el país fue el único de la región en el que los resultados de aprendizaje en Lengua y Matemática empeoraron en 3 y 6 grado de primaria, lo que ha profundizado las brechas de desigualdad y resaltado la necesidad urgente de intervenir en el sistema educativo.

En este contexto, el informe enfatiza la centralidad del nivel inicial para sentar bases sólidas en la alfabetización, y que las tecnologías digitales, si se integran adecuadamente, pueden facilitar el acceso equitativo al aprendizaje y ayudar a reducir las brechas. A lo largo del documento se analizan tanto las oportunidades que ofrecen estas tecnologías como los desafíos que plantea su implementación, incluyendo las barreras de acceso, la capacitación docente y los riesgos asociados con un uso excesivo o inadecuado de estas herramientas.
O Papel Legitimador do Conteúdo Estereotípico para a Diferença Salarial entre Homens e Mulheres
Authors: Amorim Ana Karolyne Florencio , Conceição Andreza Conrado , Pereira Cicero Roberto , Do Bú Emerson Araújo
Published: December 2024

A discriminação contra as mulheres é generalizada nas sociedades contemporâneas, e a persistente disparidade salarial para funções idênticas em comparação aos homens sugere que esse viés é socialmente justificado. Abordamos essa questão propondo que os indivíduos evocam estereótipos de gênero de uma maneira que reforça sua tendência a reafirmar as diferenças salariais de gênero. Em dois estudos, analisamos como o mero ato de evocar justificações para contratar alguém produz a disparidade salarial de gênero e se as justificativas baseadas em estereótipos medeiam esse efeito. No Estudo 1 (N = 95), manipulamos o gênero de um candidato a uma posição de trabalho e identificamos que o simples ato de justificar a contratação influencia a disparidade salarial de gênero. No Estudo 2 (N = 302), os participantes evocaram mais estereótipos de competência para um candidato a emprego do sexo masculino, e essa evocação mediou a disparidade salarial de gênero. Discutimos o papel da justificativa baseada em estereótipos na disparidade de gênero em decisões críticas dentro de contextos relacionados ao trabalho. Esses achados possuem implicações importantes para a compreensão da discriminação contra mulheres no local de trabalho e para o desenvolvimento de políticas públicas voltadas à promoção da igualdade de gênero.
CHARACTERIZATION AND CO2 STORAGE CAPACITY ANALYSIS OF THE “LU” RESERVOIR IN THE ORIENTE BASIN

Published: December 2024

The objective of this work is to determine the CO2 storage capacity of the Lower “U” reservoir and identify a sealing formation that does not compromise the integrity of the PRH field in the Oriente Basin.

Information obtained from drilled wells in the field, such as core analyses, logs, thin sections analyses, and pressure-transient analyses, were utilized to evaluate the petrophysical properties, the reservoir quality, and the reservoir fluids. Also, petrophysical properties were determined by different methods to address the uncertainty in the measurements. All these properties were utilized in the static and dynamic model to understand the behavior of the Lower “U” reservoir under CO2 injection as a mechanism to increase the recovery factor (i.e., enhanced oil recovery (EOR) through CO2 injection). The continuity and adequate CO2 storage capacity of the Lower “U” reservoir were demonstrated. The presence of a sealing formation of ultra-low permeability/porosity (shale, limestone) above the Lower “U” reservoir provides a safe geological storage system for greenhouse gases (GHG). The central area of PRH field has the best characteristics for CO2 injection due to low reservoir pressures. Additionally, the azimuth providing greater stability for the CO2 injection process was determined, preventing the generation of micro-fractures in the Lower “U” and the communication of the sandstone with other formations.

The study incorporated existing information from the oil exploration of the PRH field, and various methodologies were applied to determine petrophysical parameters. Characterizing the Lower “U” provided crucial details about the reservoir, fluids, and lithology. The theoretical storage volume for the Lower “U” reservoir was 9.13 million tons of CO2. This work is one the very first to assess the carbon capture and storage (CCS) in the Oriente Basin to reduce the environmental impact of GHG emissions.
Interpretation of Biblical Texts in Contemporary Panentheistic Discourse
Authors: Palchyk Andrii
Published: December 2024

This article addresses the issue of the interpretation of biblical texts by representatives of contemporary panentheistic thought. While examining the issue of the “God – world” relationship, they not only used fragments of the Holy Scripture to develop their concepts, but at the same time gave these fragments a panentheistic tone. Therefore, understanding the specificity of the panentheistic interpretation of such fragments in the works of individual authors becomes possible only after taking into account the internal logic of this or that concept.
The article presents the panentheistic understanding of biblical fragments in the context of Ch. Hartshorne’s processual panentheism, where certain fragments of the Holy Scripture are understood as a pattern of quasi-panentheistic thought. The paper also includes the concept of the “field of rationality” by J. Życiński; the value of biblical texts in the soteriological panentheism presented by N. Gregersen is emphasized, and the panentheistic interpretations of the description of the creation of the world in the works of Ph. Clayton and D. Griffin are discussed. The conducted analysis allows us to state that the specificity of some panentheistic concepts determines the selection of these and not other biblical texts. These texts not only emphasize God’s immanence in the world, but also His transcendence.
The Role and Significance of Monastic Chronicles in Reflecting Social and Monastic Life in Ukrainian Lands in the Background of the Chronicle From the Protection of the Mother of God Monastery in Yavoriv in the Years 1897–1935
Authors: Steblyna Yeremia Okasana
Published: December 2024

The article presents the role and significance of monastic chronicles from Ukrainian lands as an important element of reflections on the historical processes of a given era. They were written in Ukrainian, which is very close to the people’s spoken language. Keeping chronicles in monasteries was one of the main tasks of monks and nuns, who left behind a rich spiritual and historical heritage. The development of historical events in the Church and the state during those times is shown using one such chronicles, namely the chronicle of the monastery of the Protection of the Mother of God in Yavoriv in the years 1897–1935. The monastery of the Basilian Sisters in Yavoriv was the center of spiritual and cultural life for Ukrainians. The chronicle compiled there reflects not only the facts of the monastic life of the Basilian Sisters, but also events from the social, political and cultural life of the region at that time. It is a valuable source of research for both historians and linguists.

Authors: Li Siyu , Lim Chia Yean , Ang Sau Loong
Published: December 2024

The adoption of information technology for teaching and learning activities has caused technostress among teachers. The China teachers’ technostress research in the past few years was limited to factors such as techno-overload, techno-complexity, techno-insecurity, techno-uncertainty, and technoinvasion, and neglected an emerging factor which is the new technology adoption. Moreover, all the technostress research did not identify the teachers’ groups according to the technostress factors for further deliberations. This research covers the scope of technostress factors identification and teacher cluster generation among teachers in Hunan, China. A questionnaire was adopted to gather the teachers’ agreement on five technostress factors, and the responses were measured with statistical methods. The findings showed that all investigated factors have positive and significant relationships with technostress among Hunan, China’s teachers. The teachers were clustered into five distinct clusters with the K-means clustering method. This research discovered new technology adoption as a new technostress factor and successfully clustered the teachers into significant clusters to enable China’s Education Department to provide targeted technological training to the teachers.

Authors: Bina Nuraini Sri , Armanto Dian , Rajagukguk Waminton
Published: December 2024

Digital technology-based learning media is an effective tool in the development of modern education. Despite the potential, several schools have not fully implemented this tool in the learning process. For example, the competence of Indonesian students in mathematics is ranked 68th out of 81 participating countries in PISA 2022. Therefore, this study aimed to develop web-based comic in education for generation z or i-gen students using Indonesian cultural heritage. The study procedures were carried out based on the method proposed by Plomp as well as the development model. The results showed that learning media developed was valid with scores of 4.4 and 4.3 for practicality and effectiveness, respectively. In addition, 86.11% of students achieved Minimum Completeness Criteria (KKM), with 97.7% providing a positive response regarding Webtoon digital comic. The findings also revealed a significant increase in students' mathematical communication skills after the intervention, as evidenced by changes in each indicator. Based on these results, Webtoon digital comic had the potential to be developed for learning different materials and other subjects.

Published: December 2024

The paper presents results of a study the aim of which was to find out what causes difficulty in teaching technical subjects at upper secondary schools. For this purpose, a panel discussion was held with 20 selected staff members of two schools. The task of the panellists was to answer three questions: what are causes of difficulties in teaching technical subjects; what are the effective ways of motivating students to study technical subjects and how is it possible to maintain the motivation of students for a longer period of time; hence, what makes it possible to attract the attention of students more significantly in the teaching of technical subjects. The discussion was led by 3 moderators, university teachers from Slovakia, the Czech Republic and Poland. As it resulted from about 45-minute discussion of each of the stated questions, the main difficulty of technical subjects teaching is lack of students´ motivation what is partially caused by the way in which the students are assessed, and partially linked with the need to replace verbal teaching methods by other ones.
Debate Based on Inquiry Learning (DBOIL): An Innovative Learning Model to Improve Students’ Skills in Scientific Argumentation
Authors: Hendratmoko Ahmad Fauzi , Madlazim Madlazim , Widodo Wahono , Astutik Sri
Published: December 2024

In the 21st century, education places significant emphasis on developing scientific argumentation as a crucial skill. Teaching these skills requires an instructional design that allows students to construct and critique arguments actively, support claims with evidence and reasoning, and then reject opposing claims and evidence. Debate based on inquiry learning (DBOIL) is an innovative learning model that was developed and is believed to be able to facilitate these things. This research seeks to assess the influence of implementing DBOIL on enhancing students' skills in scientific argumentation. This research employed a one-group pretest-posttest design, with normalized change analysis and paired t-test. Research findings indicate that the implementation of DBOIL has demonstrably improved scientific argumentation skills, with a notable 76.67% of students exhibiting improvement in the high category. Other findings show that each phase of DBOIL significantly contributes to increasing the achievement of indicators of scientific argumentation. To maintain the reliability of DBOIL in enhancing students' skills in scientific argumentation, conducting future research on a broader scale is imperative.

Better Organisation of Occupational Pensions: What Else Can Germany Learn From the International Context?
Authors: Dombek Robert Piotr , Jurčík Radek
Published: December 2024

The organisation of occupational pension schemes in Germany is a topic worthy of further investigation, as there is an opportunity to benefit from the experience of other countries and increase the prevalence of such schemes. For instance, how might the participation and commitment of employees in company pension schemes in Germany be enhanced through the examination of international models? It is crucial to investigate how the occupational pension scheme diverges from those of other leading countries. These questions can serve as a foundation for a more comprehensive inquiry into how Germany could enhance its occupational pension scheme in light of international experience. The extant literature primarily addresses occupational pension schemes at the national level. It is evident from an analysis of the existing literature that occupational pension provision is becoming an increasingly significant aspect of the German pension landscape. This is due to the fact that an increasing number of employees view occupational pension provision as an important supplement to the statutory pension. Consequently, there has been a notable increase in the willingness to take out a pension, with figures more than doubling over the past three years. Despite an increase in willingness to take out occupational pension plans, Germany is significantly behind other countries in terms of penetration rates. An analysis of existing literature has revealed a lack of research on international occupational pension systems, highlighting the need for a comparative analysis of these systems with the German system. This paper compares selected occupational pension systems with the German occupational pension system. The sample consists of 10 selected countries. In the methodological part of the study, the differences between the international occupational pension systems are first analysed by means of a qualitative content analysis of the existing literature. In the quantitative part of the research, the differences are then evaluated using Kruskal-Wallis analysis with the statistical programme DATAtab. The results show the differences between successful occupational pension systems and are intended to offer a possible approach for the reform of the German occupational pension system.
Reinforcing Learning Management System With OBE-Based Learning Analytics and RIASEC Integration
Authors: Siang Somerset Elcid R. , Reyes Ariel Roy L. , Dumdumaya Cristina E.
Published: December 2024

The emergence of the COVID-19 pandemic brought unparalleled disruptions in people's way of living. Most transactions are done online to practice social distancing. Face-to-face classes were suspended, forcing educational institutions to migrate into flexible learning modalities. Hence, higher education institutions universally utilize learning management systems (LMS) to manage online classes. During this period, outcomes based education’s (OBE) performance was challenging to analyze. This prompted the researchers to explore the integration of OBE learning analytics and RIASEC model into existing LMS to enhance educational outcomes. OBE focuses on achieving student learning outcomes, while the RIASEC model categorizes career interests into six personality types: realistic, investigative, artistic, social, enterprising, and conventional. By combining these frameworks, educators can provide a more personalized learning experience. The integration allows for the continuous monitoring of learners’ performance, improves instructional strategies to meet individual needs, and career aspirations. This paper reviews current literature on the benefits and challenges of implementing OBE-based learning analytics and RIASEC in LMS, demonstrating how this approach can enhance student engagement, improve learning outcomes, and align educational activities with career goals. The findings suggest that this integrated approach holds significant promise for advancing personalized education and preparing learners for successful careers.
Exploring the Impact of Facebook's Reaction- Button on Interpersonal Communication: A Study on Immediacy and Social Acceleration
Authors: Padrigo Ailyn Joy P.
Published: December 2024

In recent years, the evolution of social media, particularly Facebook, has introduced tools that significantly accelerate social interactions. This study investigates the usage of Facebook’s reactionbutton and its impact on interpersonal communication, focusing on immediacy, media richness, and the societal drive for speed. This paper argues that, while the reaction-button enhances the speed and ease of communication, it may reduce the depth and clarity of interactions, potentially leading to miscommunication. This study employed a qualitative method involving in-depth interviews with 16 Facebook users. The participants provided insights into their experiences using the reaction-button and its effects on their social relationships. Results showed the widespread preference for the reaction-button over the traditional 'like' feature. Participants regard reactions as a timeefficient tool that enhances online engagement, though the immediacy of reactions sometimes undermines deeper communication. This suggests that, despite promoting faster communication, the reaction-button may undermine meaningful engagement. These findings have significant implications for understanding the evolving nature of digital interactions and highlight the need for social media platforms to balance speed with clarity.
Students’ Perceptions of the Ethical Aspects of Learning Analytics
Authors: Jagačić Tena , Kadoić Nikola , Gusić Munđar Jelena
Published: December 2024

This paper deals with the students’ perceptions of the ethical aspects of learning analytics (LA), including data privacy, students’ consent for data collection, and regulations. The existence of statistically significant differences in students with respect to gender, type of study and study year was investigated. The research included 295 Croatian students and was implemented using a questionnaire. Students are moderately concerned about privacy in LA; they want to be informed about the data collection and how the data will be analysed, as well as to decide which data will be saved. They think LA should be regulated using rules and guidelines but are unfamiliar with them. Special focus was put on the students’ attitudes towards saving information about their activities and using this data for LA, respecting the data type. Students mostly disagree with all data types being saved for LA purposes, primarily related to the history of Internet browsing and the content of e-mails, and the highest openness to saving for LA purposes is achieved for logs in learning management systems.

Authors: Catalano Horațiu , Albulescu Ion , Ani-Rus Anca , Mestic Gabriela , Cuc Maria Claudia , Rus Ana
Published: December 2024

Early education leaders need to embrace transformational leadership styles that promote growth and achievement to contribute to the success of the entire community. Research in this area is necessary because, according to conversations with school inspectors, the leaders of early education institutions in Romania need an adequate understanding of leadership styles, as seen by the lack of professional development courses available. Our research aimed to assess the impact of transformational leadership style on early education leaders' success as measured by operational indicators such as effectiveness, satisfaction, and extra effort. In this study, we employed the Multifactor Leadership Questionnaire (MLQX5) and focus group method. To determine the dominating style of the leaders in the study, correlations, regressions, and the Chi-square test were used to analyze the data. The findings indicate a connection between transformative leadership and a growth mindset that characterizes leaders. These aspects lead to high effectiveness and stimulate the individual towards continuous personal and professional development. We can conclude from the investigation that the outcomes of the leader's behavior are closely related to their leadership style and growth mindset.
Adoption of Children with “hard-to-place” Characteristics in Romania during 2016-2022
Authors: Iovu Mihai-Bogdan , Bejenaru Anca-Mioara , Raiu Sergiu-Lucian
Published: December 2024

Aim: This article examines adoption trends for children with "hard-to-place" characteristics in Romania from 2016 to 2022. The central research question is whether recent legislative changes, designed to boost the adoption process, have positively affected the adoption of these children, who are often considered difficult to place due to factors such as age, health conditions, being part of a sibling group, or belonging to an ethnic minority. Method: A secondary data analysis was conducted using official statistics from the National Authority for the Protection of Child’s Rights and Adoption (ANPDCA). The data included adoption trends and characteristics of children awaiting adoption over the study period. Results: While the number of adoptable children continued to increase over the last seven years, there was no significant increase in adoption rates for children with "hard-to-place" characteristics. Many of these children remain in the system, highlighting the ongoing challenges in finding adoptive families able and willing to meet their unique needs. Conclusions and Recommendations: The findings suggest that legislative changes alone have not been enough to improve adoption rates for this vulnerable group of children. A multidimensional education program is essential to prepare prospective adoptive parents, equipping them with the skills and knowledge needed to care for children with complex needs, thereby facilitating more successful adoptions.

The study’s international significance lies in examining language learning in a conflict zone, contributing to a global understanding of how education adapts to crisis. The study focuses on understanding and addressing students’ motivations, preferences, and habits in this unique context. A mixed-methods approach was employed, combining quantitative analysis of survey responses with qualitative insights to understand students’ perspectives. The survey, conducted among first-year students in five Ukrainian universities, identified four key aspects crucial to understanding the dynamics of language education amidst adversity: types of English language learning activities, setting language learning goals, preference for learning environments, learning modalities, and self-study habits. Each aspect provides valuable insights into students’ approaches, challenges, and motivations in their language learning journey. The findings of this study reveal a strong preference for media-based and interactive learning methods among students in Ukraine during wartime. This preference underscores the effectiveness of engaging in activities like watching movies in English and practising conversation with native speakers. The study also highlights a balanced approach to goal-setting, with a significant focus on both short-term milestones and long-term aspirations. It emphasises the importance of flexible learning environments and adaptive educational strategies in supporting language learning during challenging circumstances. Recommendations include leveraging technology, promoting goal-setting skills, and fostering supportive learning environments to enhance English language education in similar contexts.

Globalization, the economic condition and the international financial crisis have resulted in systemic changes in a variety of fields, including physical education and sports. Nationally, demographic changes and migration contributed to a large decline in the number of pupils/students in educational institutions. The current concerns facing the Republic of Moldova's sustainable growth and the European Union integration are the desired ones, requiring active participation of the school/academic communities in effecting change and achieving national/international competitiveness. According to national statistical data and the Legatum Institute's global prosperity index for 2021, "the Republic of Moldova ranks the 60th out of 167 states in the chapter "Education at a higher level than Romania (64th place), but significantly ahead of other Central and Eastern European countries" (Ministry of Justice, 2022). Management and leadership technologies, organization and personnel, methods and tactics used in (initial and ongoing) specialist training require constant improvement aimed at performance and competitiveness. In this context, the development of transformative and perspective skills in the physical education and sports systems will help to lay the groundwork for a knowledge-based society, with citizens' help in order to achieve these long-term responsibility skills, integration into society and contribution to its development. The article's strategies for teaching and developing transformative skills in students are confirmed by educational theories that give a scientific foundation for these processes.

The main scope of this study is to use plyometric means in volleyball training, individualized according to the training period, in order to improve the strength-speed capacity from the point of multidimensional perspective. The longitudinal experiment took place during the competitive year 2022-2023 and consisted in the introduction of plyometric means in training, depending on the training period, the time allocated to the improvement of strength-speed capacity being 20 minutes. We mention that the research was carried out in the gym of Dacia Pitesti Technological High School. The statistical data were collected by using the “Kistler Force Measurement Platform - Quattro Jump v1.1.1.x”. According to the results, we mention that through the use of specialized plyometric programs during training, we obtained significantly improved values in the final evaluation of the applied tests, through a significant percentage increase with a value between 7% and 25% in the group subjected to the experiment. Sports training for U17 female volleyball players is a systematic and continuous pedagogical process with the objective of improving the general motor capacity and in particular the strength-speed capacity, the functional and mental capacity, based on the adaptation of the body to the intense and maximum efforts. In conclusion, the use of specialized plyometric programs in the training of cadet female volleyball players (15-17 years), determines a faster and more extensive development of general physical training, ensures a good rest for the athletes and reveals a more efficient use of the time allocated to the training.

Background: The effectiveness of physical exercise in treating cardiorespiratory diseases is well established. Systematic training can lead to changes in morphofunctional markers; however, the degree of effectiveness varies based on the type of exercise, the intensity of the activity, as well as the age, gender, and overall health of the individual. The purpose of the research: To determine and to develop the impact of fitness activities and specialized breathing exercises on the morphofunctional state of female students with cardiorespiratory diseases. Materials and Methods: The study involved 53 female students from Lviv University of Trade and Economics, aged 18 to 19, who had cardiorespiratory diseases. Participants were randomly assigned to two groups: the experimental group (nEG=25) and the control group (nCG=28). The control group followed the traditional physical education (PE) program designed for students in special medical groups. This program included physical therapy classes, recreational walking, running, and gymnastics. The experimental group participated in individualized fitness programs that combined basic aerobics with breathing exercises for oriental martial arts. The primary markers for assessment included anthropometric measurements, indicators of the cardiovascular and respiratory systems, levels of physical development, and self-evaluations of psycho-emotional wellbeing. The experimental group was engaged in performance of the developed individualized fitness programs using basic aerobics combined with sets of breathing exercises for oriental martial arts. The main markers were anthropometric ones, those of the cardiovascular and respiratory system, physical development and self-assessment of the psycho-emotional state. Results: The results indicate that the experimental program significantly improves various health markers, including body mass index, circumferential measurements, thoracic excursion, heart rate, blood pressure, Robinson index, lung vital capacity, respiratory rate, vital index, and recovery time following a functional test. Conclusion: The recorded and statistically analyzed results indicate that a basic aerobics program combined with specific breathing exercises for oriental martial arts is effective. This program improves the studied markers and contributes to positive changes in the morphofunctional profile. These changes are significant for enhancing the health status of female students with cardiorespiratory diseases.
