Los residuos sólidos urbanos (RSU), al ser vertidos sin tratamiento adecuado, ocasionan daños severos al ambiente influyendo en la calidad de vida de la población, razón por la cual actualmente se le presta atención diferenciada al vertido de residuos urbanos. En este trabajo se evalúa la fracción orgánica de estos residuos (FORSU), tomando como referencia el grupo poblacional de una de las Residencias estudiantiles de la Universidad de Oriente. La generación de FORSU en la residencia es de 0,06 kg/hab/día, con un contenido de sólidos totales de 30,9 ± 5,3 % de los cuáles el 81,7 ± 0,6 % son sólidos volátiles. Se evalúa el funcionamiento de un reactor en lote de lecho escurrido, que permitió un tratamiento discontinuo e in situ de la FORSU, en codigestión anaerobia con un 25 % de estiércol vacuno en una primera etapa. También se evalúa, en una segunda etapa, el tratamiento anaerobio para los lixiviados que se generan en el reactor en lote, empleando un reactor UASB. En el reactor en lote se alcanzó una remoción de sólidos volátiles del 44,1 %, mientras que en el reactor UASB se removió un 81,2 % de DQO. Como resultado del sistema de tratamiento evaluado, se alcanzó una productividad total de 5,37 LCH4·kgSV-1·d-1.

En este trabajo se determinó la residualidad de plaguicidas organofosforados (OF) y organoclorados (OC) en los frutos de dos solanáceas comúnmente consumidas en la dieta diaria de la población del departamento del Quindío (Colombia): tomates (Solanum lycopersicum L.) cosechados en cultivos regionales y uchuvas (Physalis peruviana L.) obtenidos en mercados de cadena. Con el fin de evaluar la calidad con la que se comercializan estos frutos, se midieron parámetros fisicoquímicos tales como el pH y la concentración de sólidos solubles (°Bx). El análisis de los plaguicidas en piel y pulpa de ambos frutos se realizó mediante cromatografía de gases con detección por microcaptura de electrones (GC-μ-ECD), empleando técnicas de extracción en fase sólida como pretratamiento de muestra. Como resultado del análisis cromatográfico se encontró la presencia de un total de 10 plaguicidas OF y OC tanto en la piel como en la pulpa de ambos frutos, algunos de ellos en concentraciones mayores a 0,13 ppm en tomate y 0,39 ppm en uchuva. Los resultados obtenidos en este estudio sugieren una alta residualidad de este tipo de fitosanitarios y ponen de manifiesto el uso desmesurado de estas sustancias en el cultivo de frutos de consumo masivo como el tomate y la uchuva. Esto revela el uso de malas prácticas agrícolas y la falta de un control más riguroso sobre el empleo de estos agroquímicos. In this work was studied the residuality of organophosphorus (OP) and organochlorinated (OC) pesticides in fruits of two Solanaceae species which are commonly consumed in the daily diet by the population of Quindio, Colombia: tomato (Solanum lycopersicum L.) from regional crops, and cape gooseberry (Physalis peruviana L.) obtained from supermarkets. In order to evaluate the quality in which the fruit is commercialized, physicochemical parameters as pH and soluble solids concentration (°Bx) were measured. The skin and pulp pesticides analysis in both fruits was performed using gas chromatography with microelectron capture detection (GC-μ-ECD), and employing solid-phase extraction techniques as sample pretreatment. The result of the chromatographic analysis showed the presence of 10 different OP and OC pesticides both in the skin as well as in the pulp of both fruits, some of them in higher concentrations than 0.13 ppm for tomatoes and 0.39 ppm for gooseberries. The results found in this study suggest the high residuality of these substances, revealing the disproportionate use of these pesticides in the cultivation of consumer crops as tomatoes and gooseberries. In this sense, this work suggests that the agricultural practices are poorly implemented revealing the lack of a more rigorous control over the use of these agrochemicals. Neste trabalho, determinou-se a residualidade de praguicidas organofosforados (OF) e organoclorados (OC) nos frutos de duas solanáceas comumente consumidas na dieta alimentar da população do estado de Quindío (Colômbia): tomates (Solanum lycopersicum L.) colhidos em cultivos regionais e physalis (Physalis peruviana L.) obtidas em redes de supermercados. A fim de avaliar a qualidade com a qual são comercializados, mediram-se parâmetros físico-químicos, como o pH e a concentração de sólidos solúveis (°Bx). A análise dos praguicidas na pele e na polpa de ambos os frutos se realizou por meio de cromatografia de gases com detecção por microcaptura de elétrons (GC-μ-ECD), empregando técnicas de extração em fase sólida como prétratamento de amostra. Como resultado da análise cromatográfica, constatou-se a presença de um total de dez praguicidas OF e OC tanto na pele quanto na polpa de ambos os frutos, alguns deles em concentrações maiores a 0,13 ppm em tomate e 0,39 ppm em physalis. Os resultados obtidos neste estudo sugerem uma alta residualidade desse tipo de fitossanitários e evidenciam o uso desmedido dessas substâncias no cultivo de frutos de consumo massivo como o tomate e a physalis.

Se analizó la formación de clases de estímulos equivalentes vía reglas verbales mediante la utilización de un procedimiento de igualación de la muestra en un formato de “papel y lápiz” para el entrenamiento y evaluación de discriminaciones condicionales. Participaron voluntariamente 36 estudiantes universitarios; el grupo experimental recibió entrenamiento de línea base vía reglas verbales, pruebas de mantenimiento de línea base y pruebas de equivalencia; el grupo control sólo recibió las pruebas. El instrumento desarrollado mostró ser efectivo. Un número considerable de participantes del grupo experimental logró formar dos clases de estímulos equivalentes, a diferencia del grupo control en que ninguno de los participantes formó las clases. El desarrollo de procedimientos efectivos con “papel y lápiz” y reglas, podría apoyar la enseñanza de habilidades básicas de lectura en poblaciones grandes con economía de tiempo y dinero. Equivalent class formation through verbal rules was analyzed. A matching-to-sample procedure for training and probing of conditional discriminations in a “paper and pencil” format was used. Participants were 36 voluntary students, divided in two groups. The baseline training for the experimental group was carried out via verbal rules. This group also received maintenance probes and equivalence probes during the baseline period. The control group was only given the probes. The instrument used proved to be effective. The majority of participants in the experimental group formed two equivalent classes, unlike the control group in which none of the participants showed class formation. The development of effective procedures using “paper and pencil” and verbal rules format, could support the teaching of basic reading skills in large populations with a resulting economy of time and money.

State and federal mandates for education reform call for increased accountability and the inclusion of students with disabilities in all accountability efforts. In the rush to implement high-stakes education reforms, particularly those involving tests or assessments, the particular needs of students with severe cognitive disabilities are only now being addressed by policymakers and educators. For students with significant cognitive disabilities, implementation of alternate approaches to education accountability is increasing. At the same time, the challenges associated with successfully implementing alternate assessment programs are becoming more obvious. This paper describes some of the ways in which alternate assessment as part of standards-based education reform may impact students with significant cognitive disabilities. It provides an overview of state efforts to implement alternate assessments for students with significant cognitive disabilities, followed by an example of how one state has begun to implement alternate assessment through the Massachusetts Alternate Assessment (MCAS-Alt/ Massachusetts Comprehensive Assessment System Alternate). It reviews issues educators in all states will face in the participation of students with significant disabilities in alternate assessment programs, the content and form of alternate assessments, the validity and reliability of the assessments, and the role of teachers in the implementation of alternate assessment programs. ,Education - Published

Introduction The rising prevalence of electronic cigarette (e-cigarette) use has prompted concerns regarding its potential health implications. While much attention has focused on respiratory and cardiovascular effects, injuries, oral trauma, and bone fractures linked to e-cigarette use have received less scrutiny. This paper aims to comprehensively review the landscape of injuries, oral trauma, and bone fractures induced by e-cigarettes, shedding light on this underexplored facet of e-cigarette-related harm. Material and Methods This literature review has analyzed 16 papers. Inclusion criteria: researches and case reports published after 2015. PubMed and Google Scholar has been searched to identify the papers. Analysis of the Literature Existing literature suggests a growing incidence of injuries, oral trauma, and bone fractures associated with e-cigarette use, albeit with limited systematic investigation. Mechanisms underlying these injuries range from device malfunctions to inadvertent impacts during use. Case reports highlight a spectrum of injuries, including oral burns, dental trauma, and skeletal fractures, often involving the face and mouth regions. Conclusions Despite the lack of comprehensive epidemiological data emerging evidence underscores the need for heightened awareness and preventive measures to mitigate e-cigarette-related injuries. Enhanced education, regulation of e-cigarette devices, and promotion of safer usage practices are crucial steps towards reducing the burden of e-cigarette-related harm on oral and skeletal health.

El biodiesel es un biocombustible producido a partir de grasas yaceites, y debido a las desventajas del uso de los combustiblesfósiles, su producción y consumo ha aumentado en los últimosaños. En este trabajo fue estudiada la esterificación por catálisisácida y la transesterificación alcalina de aceites residuales paraobtener biodiesel. Las condiciones de relación aceite-metanol (6:1 y5:1) y concentración de catalizador fueron variadas para seleccionarlas más favorables para el proceso. Los aceites usados fueronrecolectados en restaurantes de la ciudad de Cartagena. Seencontró que la variable con mayor efecto en el rendimiento de lareacción fue la relación aceite-metanol, favoreciéndose para bajasconcentraciones de metanol (6:1), a las cuales se obtienenrendimientos superiores al 93%. La concentración de catalizador noinfluyó de manera significado la eficiencia de la esterificación. Elbiodiesel obtenido presentó buenas características de acidez y bajocontenido de azufre. Adicionalmente, se evidenció la necesidad deun pretratamiento a los aceites y una purificación del biodiesel paralograr el cumplimiento de estándares internacionales. Biodiesel is a biofuel produced from fats and oils and because of thedisadvantages of fossil oils use, its production and consumption hasincreased in recent years. In this work the esterification of waste oilby acid catalysis and alkaline transesterification to obtain biodieselwas studied. The oil-methanol (6:1 and 5:1) ratio conditions andcatalyst concentration were varied to select the most favorable forthe process. The oils used were collected in restaurants in the city ofCartagena. It was found that the variable to greater effect on thereaction yield was the oil-methanol ratio, favoring low concentrationsof methanol (6:1), from which yields higher than 93% are obtained.The catalyst concentration did not affect significantly the efficiency ofesterification. The biodiesel obtained had good acidity characteristicsand low sulfur content. Additionally the need for a pretreatment to oils and biodiesel purification to achieve compliance of international standards was evidenced.

La aspiración actual de la Educación Científica de enseñar a las personas cómo enfrentarse a problemas, de desarrollar destrezas de alto nivel intelectual al mismo tiempo que conocimientos específicos, queda reducida en la enseñanza habitual de la Física a la resolución de problemas de “lápiz y papel” al final de los temas. Sin embargo, el fracaso generalizado de los alumnos en esta actividad requiere poner en cuestión si, de verdad, se les está enseñando a resolver problemas. El análisis realizado de textos y profesores pone en evidencia que no se les enseña a resolver problemas, sino que se les explican soluciones ya hechas, transmitiendo serias deficiencias actitudinales y metodológicas que hacen enormemente difícil que puedan tener éxito ante nuevos problemas. One of the expectations in Science Education nowadays is to teach people how to solve problems, to develop high-level intellectual skills at the same time that specific knowledge is acquired. In common practice of Physics Education, this objective is usually limited to solving “paper and pencil” problems appearing at the end of each book chapter. However, the widespread failure of students in this activity forces us to question if, indeed, we are teaching them how to solve problems. An analysis of both textbooks and teachers’ practices shows that students are not taught how to solve problems but, instead, ready-made solutions are just explained to the students. This procedure transmits serious deficiencies both in attitudinal and methodological terms, which makes it very difficult for them to tackle new problems.

Human capital theory (HCT) has moved from a core tenet of neoclassical economic theory to a normative and prescriptive policy position that guides our understanding of economic growth across multiple scales, from the individual to the national. In this paper, a diverse group of graduate students interrogate their experiences of accumulating and realising ‘human capital.’ They argue that HCT holds at its centre an abstract and falsely universal subject that obscures how transnational relations of patriarchy, race, and coloniality constitute class relations and thus create a reality in which investments in human capital cannot be realised by all. This paper further elaborates how this group of adult learners developed an understanding of class as a socially constituted relation within capital and thus foregrounds the need for adult educators to work from a more nuanced articulation of class that recognizes relationality with other forms of oppression.

Introduction and purpose Non-specific and specific lower back pain syndrome is one of the leading causes of musculoskeletal disability and affects more than half of the population worldwide. The aim of this paper is to confront the problem of lumbar pain, possible diagnostic options, conservative and surgical opportunities with long term satisfactory rate. State of knowledge The paper reviews literature on lower back pain syndrome, sciatica, radiculopathy and lumbar disc herniation in regards to detection of the problem, classifying it and possible methods of resolvement. The WHO defines lower back pain as one of the leading causes of musculoskeletal dysfunction and it focuses on reducing the occurrence by programs like WHO Rehabilitation 2030 Initiative, UN Decade of Healthy Ageing and others. The paper also focuses on non surgical options of treatment. Material and method A review of the literature available in the “PubMed” and Google Schoolar was conducted. We focused on differential diagnosis depending on clinical presentation and possible treatment methods depending on symptoms, pathogenesis of the disorder and available procedures. Summary Our review managed to present the current state of development, possible differential diagnosis, prevalence of neural compressions, sciatica and radiculopathy in different diagnostic options. By receiving multiple studies we confront varied opinions of specialists regarding the approach to lower back pain syndrome and favorable forms of care. Additionally we came to the conclusion that the difference of patients' long term satisfactory rate in regards to nonoperative and operative treatment is not significant, and flattens over the years.

Gilbert’s syndrome is the most common inherited jaundice worldwide. It affects 5-10% of the population. It is caused by a mutation of the UGT1A1 gene, which results in impaired bilirubin metabolism. It is a benign disease and does not affect the life expectancy of patients. Patients with Gilbert’s syndrome should be alert to factors that exacerbate the course of the disease, interactions with medications taken and possible comorbidities such as hemolytic anemia, cholelithiasis or schizophrenia. However, it is the responsibility of physicians with such patients under their care to properly educate patients. Gilbert’s syndrome carries not only the consequences associated with the mutation, but also has many benefits that patients may not be fully aware of. Mildly elevated bilirubin levels have an antioxidant and anti-inflammatory effect, which prevents the development of lifestyle diseases and cancer. Ongoing clinical trials suggest that this could be a great step toward new treatments for diseases affecting the entire human population. PURPOSE OF THE WORK: This review paper aims to show Gilbert’s syndrome as a multifaceted disease and to sensitize doctors' attention to patients with the described mutation. MATERIALS AND METHODS: An analysis of papers available in PubMed and Google Scholar was performed using the following key words: Gilbert’s syndrome, bilirubin, UDP-glucuronosyltransferase, Gilbert’s syndrome harmful and protective aspects, iatrogenic Gilbert’s syndrome RESULTS: The result of the work is to present Gilbert’s syndrome as a disease that carries medical problems directly related to the mutation, but also, in some cases, has a protective effect on affected individuals. The work highlights the complexity of the problem.

Introduction and purpose: Diabetes has emerged as a global lifestyle disease, with an alarming rise in cases, particularly of type 2 diabetes. In Poland, over 3 million people are diagnosed, and an estimated 4 million cases are expected by 2030. Effective treatment involves a multifaceted approach, including dietary intervention, physical activity, and pharmacological options. Incretins, such as glucagon-like peptide-1 (GLP-1), play a pivotal role in carbohydrate metabolism regulation, and GLP-1 analogs have become essential in managing type 2 diabetes. This paper explores the development and mechanisms of GLP-1 analogs, detailing their impact on insulin secretion, gastric emptying, and weight reduction. Description of the state knowledge: Various GLP-1 receptor agonists, including exenatide, liraglutide, dulaglutide, semaglutide, and the novel tirzepatide, are discussed. These drugs exhibit diverse pharmacokinetics, modes of administration, and effects on glucose metabolism and weight. Despite their efficacy, there is a concerning trend of off-label use, particularly for obesity treatment, leading to shortages for patients with valid prescriptions. This misuse is fueled by para-advertising on social media platforms, contributing to a surge in prescriptions and reimbursement costs. To address this, guidelines for GLP-1 analog use in obesity treatment are proposed, emphasizing the need for a stable drug supply and normalizing drug availability. Summary: In 2023, concerns intensified with reports of counterfeit GLP-1 analogs, prompting regulatory interventions. The paper concludes by underscoring the critical role GLP-1 analogs play in diabetes and obesity treatment, while emphasizing the importance of responsible prescription practices, guidelines adherence, and regulatory vigilance to ensure patient safety and mitigate the risks associated with misuse and counterfeit drugs.

Effective body posture entails the correct alignment of body parts in relation to each other and is crucial for preserving balance, stability, and the efficient operation of muscles and joints. The major types of posture abnormalities such as lordosis, kyphosis and scoliosis can lead to alterations in various areas of the body, such as stomatognatic system. The potential correlation between malocclusion and body posture remains a subject of controversy. The aim of this review is to investigate and evaluate the association between posture defects and malocclusion on the basis of literature. This literature review has analyzed 18 studies. Inclusion criteria: clinical researches published after 2010, regarding children and adults. PubMed and Google Scholar has been searched to identify the papers. In 18 analyzed studies, 2133 patients were enrolled (including 979 children aged 4-18). A positive correlation between scoliosis and different types of malocclusion has been proven by six papers. There are also other noteworthy dependencies, such as overjet and pelvic torsion, kyphosis and sagittal position of mandible, skeletal Class III and torticollis, cross bite and scapula plane. Adolescent Idiopathic Scoliosis significantly affects the stomatognathic system, leading to issues like crossbite, crowding, increased overjet, overbite, partial open bite, and midline deviation. Orthopedists should collaborate with orthodontists for comprehensive treatment, particularly during developmental stages.

Introduction and purpose The term "probiotic" rooted in Latin, signifies 'for life,' reflecting the historical use of fermented products for therapeutic purposes. While browsing many websites devoted to healthy eating or popular science topics, we often came across the topic of probiotic food without any confirmation by scientific research. The aim of this paper is to confirm or exclude the presence of probiotics in popular foods. State of knowledge The paper reviews literature on the health benefits of various food that is traditionally considered probiotic, focusing on how they impact on varied health conditions. Defined by the WHO as living microorganisms conferring health benefits when consumed adequately, probiotics, mainly bacteria from Lactobacillus and Bifidobacterium genera, play a vital role in maintaining gut microbiota balance, regulating digestion, supporting the immune system and influencing mental and cardiovascular health. In addition, the paper also searches for scientific basis for their action. Material and methods A review of the literature available in the “PubMed” and Google Schoolar was conducted. We focused on checking whether the microorganisms contained in pickled food meet the WHO criteria for probiotics. Summary Our review managed to prove the probiotic effect of almost all presented food, except for miso. By reviewing many articles, we shed a lot of uncertainty on the repeated myth about the lack of probiotic effect of cucumbers preserved in vinegar and what is more, we found scientific assumptions about the probiotic effect of vinegar itself. Fermented food contains numerous strains of bacteria that are resistant to acid, bile and temperature in the human digestive tract and can be effectively used as a source of probiotics. Additionally, compared to probiotics from the pharmacy, fermented products provide not only probiotics, but also nutritional value, valuable fiber and vitamins, benefiting to our health.

Introduction and purpose: The purpose of this scientific paper is to review the current knowledge of the effects of red wine on human health, particularly with regard to cardiovascular disease. State of Knowledge: Since the 1990s, red wine has gained its status as a health-promoting alcohol through the French Paradox - when drunk in moderate amounts, it protects against cardiovascular disease. The authors have collected scientific papers on the health effects of alcohol, red wine and resveratrol-a polyphenol that is the main component with health-promoting effects of wine. On their basis, they analyzed the assumptions of the positive effects of wine reaching inconclusive conclusions. Summary: Despite the fact that both ethanol and resveratrol have a positive effect in in vitro studies, in population studies their effect is much less significant, either because the negative behavioral-health effects in the case of ethanol are omitted or the actual effective doses of resveratrol are omitted.

Context: Angular gyrus is an anatomical structure of the brain located in the parietal lobe, taking part in writing and reading, language-use, memory and attention and spatial recognition. It is supplied by the angular gyrus artery, which is one of the caudal branches of the middle cerebral artery. One of the clinical pathologies of the angular gyrus artery is the ischemic stroke of the angular gyrus in the dominant hemisphere, responsible for the presence of Gerstmann Syndrome: left-right disorientation, agraphia, alexia, acalculia and finger agnosia. This systematic review aims to present the variety of anomalies of the main cerebral artery and the angular gyrus artery. Objective: Preparing a systematic review of papers describing the course anomalies of the angular gyrus artery. Materials and methods: PubMed and Google Scholar electronic databases was searched for phrases: ‘Angular gyrus artery’, ‘Artery of angular gyrus’, ‘Middle cerebral artery branches’, ‘Branches of middle cerebral artery’, ‘Gerstmann Syndrome’ published between years 2015 and 2023. Also 3 papers published before 2000 were used. From the selected 30 papers, 6 were used to prepare this analysis. Results: The middle cerebral artery, from which arises the angular gyrus artery, is marked by a significant variety of its division, mainly the number of the dividing trunks of the artery. Depending on the type of the division, the angular gyrus artery can arise from the upper, middle or lower trunk and vary in sizes. It can also appear as a singular or two separate branches. Instances of the anomaly of both the angular gyrus artery and posterior parietal artery are rare, but reported. Conclusions: The angular gyrus artery is characterised by a number of anomalies in its course, separation from the middle cerebral artery, diameter and branching.

Introduction and aim Diabetic foot ulcer (DFU) is a chronic condition that affects an increasing number of people each year[1]. Healing the ulceration requires cooperation between patients, specialists and scientists in order to achieve satisfactory results. Treating this type of wound is not only a therapeutic challenge[1,2,3,4,5,6], but also an economic one, which is why so much scientific research has already been made on this phenomenon[2,3]. Still scientists continue their quest for new cost-effective alternatives to current therapeutic options that would be consistent with contemporary knowledge and available engineering capabilities in pursuance of creating techniques and new dressings that will accelerate the healing of DFUs[2,3,7,8]. Factors such as stress, obesity, certain medications, and chronic diseases appear to negatively affect the process of repair [1,9,10,4,6,11]. Studies prove that aloe vera gel due to its healing properties, can be considered as a potential dressing that will expedite the mending process of diabetic foot ulceration[12,13,14]. In this paper, we performed a literature review of the applicability of aloe vera in the healing process of DFUs. Materials and methods Searching the available literature, including randomized clinical trials and systematic reviews, we drew on databases focusing on the effects of treatment for diabetic foot ulceration using Aloe vera. Conclusion: The current scientific research on the use of Aloe vera gel in diabetic foot ulcer treatment indicates that this method is safe, effective and inexpensive[2,3]. However the difficulty of treatment and the increasing prevalence of this type of wound pose a challenge to finding new solutions and exploring mechanisms in which aloe vera can have a possible role in the wound healing process. Nevertheless, this paper presents a promising impact of Aloe vera gel applicability in the healing process of diabetic foot ulcer.

Introduction and purpose: Currently, as the frequency of obesity is alarming, the role of many factors that could contribute in preventing and treating this condition are being researched, among them the certain food with beneficial health profiles - one of them is soybeans, specifically the isoflavones it contains. Populations that consume soy are known for lower risk of various disorders - among them obesity. The aim of this paper is to summarize the existing paper about the role of these bioactive components in the treatment of this condition. The search was conducted using PubMed and Google Scholarship databases. Brief description of the state of knowledge: Obesity is one of the leading challenges in today’s healthcare as it leads to various chronic diseases that are fraught in consequences. Current knowledge is pointing into the association between composition of the soy isoflavones and the lower risk of obesity. Results of the studies indicate that patients affected with obesity could benefit from introducing soy isoflavones into their diet along with other necessary modifications. Conclusions: Soy isoflavones are potential agents in the holistic obesity treatment. Consumption of isoflavones merits further recognition as foregoing results of conducted studies are pointing to its possibly meaningful role. It is worth mentioning that consumption of soy isoflavones is not only an anti-obese factor, but also presents various other health benefits and when consumed rationally poses no risk to human’s well being. We conclude that further studies would enable us to fully reveal the potential of those polyphenols.

RESEARCH OBJECTIVE: The research investigates how young boys progress in life after the loss of their fathers. It explores the adjustments they make, the coping mechanisms they develop to navigate life, and the male roles they assume in the family. Additionally, it examines how family can aid and support their coping and adjustment process. THE RESEARCH PROBLEM AND METHODS: This study utilises a case study methodology focused on gaining an understanding of the lives of two adolescent boys who experienced the death of their fathers in the early formative years of their lives. THE PROCESS OF ARGUMENTATION: The paper focuses on five themes- family dynamics, life transitions with and without their fathers, post-loss reassignment of family roles, present circumstances, and future goals. RESEARCH RESULTS: A qualitative analysis of the data revealed that participants’ belief systems, family support, and striving toward future goals helped them to be resilient in this event. CONCLUSIONS RECOMMENDATIONS AND APPLICABLE VALUE OF RESEARCH: While most research typically emphasises the negative impacts of death on people, this study demonstrates how individuals’ can be resilient, dependent on both person-related factors and environmental factors. To help adolescents who are grieving become resilient, the paper offers intervention and coping strategies through counselling, the availability of support networks, and combined efforts by the state and educational institutions.

RESEARCH OBJECTIVE: Governments across the world were forced to impose social distancing and lockdown measures to prevent the spread of COVID-19, caused by coronavirus SARS-CoV-2 that emerged in December 2019. Following the declaration of COVID-19 as a pandemic, the disruptions, including restrictive measures such as school closures had severe impacts on the physical, emotional and mental health of all people, especially children with special needs. There was also scant data, particularly in low-to-middle-income countries. Existing literature stems mostly from western countries, thus the need to perform a comprehensive review on this topic. THE RESEARCH PROBLEM AND METHODS: The primary objective of the systematic review is to understand the impact of COVID-19 and restrictive measures such as school closures on the educational outcomes and physical and mental health of school-going children with special needs. THE PROCESS OF ARGUMENTATION: This systematic review used the PRISMA 2020 checklist where four databases and grey literature were searched for full text articles, peer reviewed publications in the English language that were published during January 2019–December 2021. RESEARCH RESULTS: The literature search identified 1294 publications, of which 25 key papers were selected. These studies investigate the impact on children with special needs across the globe, with a majority of papers from Europe. We found that COVID-19 and the digitalization of schooling had severe impacts on the physical and mental health of children with special needs and their parents/caregivers. CONCLUSIONS, RECOMMENDATIONS AND APPLICABLE VALUE OF RESEARCH: These studies highlight the need for an inclusive school environment to ensure that the learning outcomes for children everywhere are achieved. Further, a hybrid model that includes classroom learning with novel inventive methods would be beneficial for children with special needs.

Argument Maps ,multimodal contexts ,post-digital ,new media literacies ,Education - Abstract
The post-digital era is characterised by the vast presence of platforms that impose their digital affordances and algorithmic control on our behaviour. This environment is challenging education and training, with implications for digital and transmedial literacy. Investigating instructional methodologies is crucial to fostering critical comprehension of such novel informational environments. Argument maps (AMs), which were first created and evaluated in static information contexts (analogical/old web), could be useful in the emergence of dynamic (post-digital) textual forms. The current paper describes a comprehensive literature review based on the above assumptions. We looked into state-of-the-art research on using AMs to handle dynamic information. We found 150 papers using a PRISMA procedure and then examined 19 of them. Our review produced pertinent data about the current state of AMs, including the types of texts on which they are used and the tools (especially digital and artificial intelligence [AI]-based) that have been employed. Our research lays the groundwork for teaching the literacies needed in new informational settings, such as multimodal, dynamic, algorithmic and data-driven contexts, with a specific focus on AMs as effective mediational tools.

The dynamics of in situ 2D HeLa cell quasi-linear and quasi-radial colony fronts in a standard culture medium is investigated. For quasi-radial colonies, as the cell population increased, a kinetic transition from an exponential to a constant front average velocity regime was observed. Special attention was paid to individual cell motility evolution under constant average colony front velocity looking for its impact on the dynamics of the 2D colony front roughness. From the directionalities and velocity components of cell trajectories in colonies with different cell populations, the influence of both local cell density and cell crowding effects on individual cell motility was determined. The average dynamic behaviour of individual cells in the colony and its dependence on both local spatio-temporal heterogeneities and growth geometry suggested that cell motion undergoes under a concerted cell migration mechanism, in which both a limiting random walk-like and a limiting ballistic-like contribution were involved. These results were interesting to infer how biased cell trajectories influenced both the 2D colony spreading dynamics and the front roughness characteristics by local biased contributions to individual cell motion. These data are consistent with previous experimental and theoretical cell colony spreading data and provide additional evidence of the validity of the Kardar-Parisi-Zhang equation, within a certain range of time and colony front size, for describing the dynamics of 2D colony front roughness., Instituto de Investigaciones Fisicoquímicas Teóricas y Aplicadas

This study considers TED talks as an effective authentic resource for mastering English. The purpose of the article is to outline a methodology for using TED talks in teaching English for specific purposes (ESP) at the university level. To achieve this goal, we set the following objectives: to introduce and describe the steps of utilizing TED talks, as well as provide examples to each step. We applied a number of methods which helped to fulfil the task of the paper. They include establishing the cognitive and educational value of ESP and its place in the system of university education; defining the tasks and its content of the discipline; developing methodical means and organizational forms of training according to these tasks and content. TED talks are informative presentations delivered by experts in their fields. They provide a great opportunity for language teachers to incorporate authentic listening and speaking tasks in their teaching methods. A welldesigned lesson plan that utilizes TED talks as a teaching tool can benefit ESP students in various ways. The methodology of incorporating TED talks in the teaching process should involve a series of steps that aim to maximize effective learning outcomes. These steps include selecting the theme of the talk, searching the TED talk, delivering the speech, designing pre-listening and post-listening activities. The article presents examples of exercises that can be done at each step with reference to specific TED talks from the site https:// ed.ted.com. The first step ensures that the chosen TED talks are suitable and engaging. Teachers can provide students with choices and allow them to vote. The aim of the second step is to support students’ understanding of the TED talk. The third step develops listening comprehension skills. The fourth step engages and promotes students’ active listening skills. The fifth step helps to develop skills of discourse analysis. The video content that the teacher chooses for the lesson should correspond to the professional interests of students. In such a way this video will be able to increase the motivation to study not only a foreign language but also specialized disciplines. The work with TED talks, however, differs from ordinary academic lectures and presentations. Thus, it requires special training of both the teacher and students. Firstly, students` level of English is an important factor defining the choice of a lecture. The teacher considers the level of listening skills, knowledge of the topic, and terminology. Secondly, it is important to take into account the duration of the presentation. If students are not familiar with the topic, they can have some difficulties with comprehension. Therefore, they will need to listen to the lecture twice. So, the preferable length of the video should be about 5-6 minutes. Incorporating TED talks as a teaching tool in English for Specific Purposes can be a highly effective way of promoting active learning in the classroom. TED talks are a source of authentic and relevant topics for students to engage in while providing a more enjoyable and efficient way of learning. The methodology of using videos from the resource has clear benefits. They include improving comprehension skills, vocabulary acquisition, note-taking, and speaking skills. By following the steps mentioned in this paper, lecturers can deliver enriching, pedagogical sessions that will provide students with a foundation to become successful professionals in their respective fields.

The issue of the relationships between anxiety and aggressiveness among Ukrainian women in war conditions has been dealt with in this article. The relevance of the chosen topic is beyond doubt, since social problems based on psychological factors are especially relevant during the war. It is substantiated that a change in the usual living conditions leads to a significant increase in anxiety and aggressiveness among women. In this paper, the attention is paid specifically to the study of anxiety and manifestation of aggressiveness by women who are in war conditions. It is worth noting that currently in the psychological and social literature, the number of publications about the problem of anxiety is increasing, since anxiety occupies a special place, as it often leads to a decrease in work capacity, productivity, difficulties in communication, etc. It has been found out that the level of anxiety can be manifested in the aggressive women’s behaviour in the war conditions. It is noted that the state of anxiety and aggressiveness is the most common phenomenon among women in war conditions. The results of the analysis and generalization of scientific sources are presented in this paper. It has been identified that the problem of anxiety and aggressiveness is one of the topical issues of modern psychology. The need for timely identification and work with the anxiety, anxious behaviour and aggressiveness of women in war conditions and after military aggression has been emphasized. The analysis of the questionnaire conducted among Ukrainian women in war conditions has been carried out, and the degree of their influence on women’s daily lives and life activities in war time has been determined. The purpose of this work is theoretical substantiation and empirical study of the specific of the relationships between anxiety and the manifestation of aggressive behaviour of Ukrainian women in war conditions. The object of this study is the anxiety of Ukrainian women in war conditions, whereas the subject of this study is the character of the relationship between anxiety and the manifestation of aggressiveness of Ukrainian women in war conditions. The conceptual hypothesis of this research lies in the assumption of the presence of significant relationship between anxiety and the manifestation of aggressiveness of Ukrainian women in war conditions, and it has been fully confirmed. Considering the influence of war conditions on the anxiety and aggressiveness of Ukrainian women, the relationship between the mentioned psychological categories has been claimed. It has been revealed that the state of anxiety can be manifested in the aggressive behaviour of women in war conditions. It is noted that the state of anxiety and aggressiveness is the most common phenomenon among women in war conditions. According to the results of this study, there have been identified those significant relationships between indicators of anxiety and certain forms of aggressiveness among Ukrainian women in war conditions. It is substantiated that the high level of manifestation of anxiety is caused by certain psychological features. It has been found out that the increase in the level of anxiety, indicators of family anxiety and anxious behaviour is associated with an increase in the level of aggressiveness of Ukrainian women. The practical significance lies in the fact that the obtained results can be used by employees of psychological services, practical psychologists during counselling at various stages of psychotherapeutic work with women in war conditions.

RESEARCH OBJECTIVE: The aim of the paper was to discuss a function of passion in professional personal lives of eminent Cracow musicians. THE RESEARCH PROBLEM AND METHODS: The paper raises the problem of the role of passion in the process of shaping musical eminence, answers the question of the scope of experiencing it as well as it manifesting in activities of outstanding individuals. In conducted research and interpretations, the qualitative perspective and biographical method were applied. The leading technique was problem-concentrated qualitative interview, partially structured, carried out with ten eminent instrumentalists. THE PROCESS OF ARGUMENTATION: The theoretical basis for this reading of the experience of educational biographies was provided by the Model of Authentic Vocation of J. Weller and the Dualistic Model of Passion of A. Bonneville-Roussy, G. Lavigne and R. Vallerand. The interpretations of the research material described the topography of experiencing passion. RESEARCH RESULTS: The article describes autonomous passion associated with musical mastery, instrumental motivation to practice, as well as distinguishes important factors that determine the experience of passion, persistence or burnout (tenacity, ambition, community transfer, conflict of motives, work overload), and concretizes the qualities of musical passion of outstanding musicians: professionalization, love of music, integrity, creativity, strength and determination in pursuit of goals, as well as humility in the face of challenges. CONCLUSIONS, INNOVATIONS AND RECOMMENDATIONS: Deciphering the senses and meanings that prominent Cracow musicians attributed to passion suggests that it was autonomous, harmonious and instrumental, motivated by the pursuit of mastery, and that the trajectories of the musicians’ professional biographies were a manifestation of a “professionalization of passion,” which formed the core of their educational experience and constituted and defined their life creed.

Early childhood education corresponds to the first stage of the basic education system, whose purpose permeates the integral development of the child, which requires, among other things, the establishment of a broader and more effective academic debate about this stage. Thus, this study emerges with the objective of mapping the Course Completion Papers (TCCs) of the Federal University of Tocantins (UFT) that addressed this theme in the scope of their work. For this, a documentary research was carried out, analyzing the TCCs elaborated by the graduates of the courses offered by the campus of Tocantinópolis. The results indicate that in a universe of 159 papers available in the institution's Repository, only 12 addressed aspects related to Early Childhood Education, including from normative aspects to the pedagogical challenges of daily day care centers and preschools. It is concluded that the academic interest of these graduates is still configured from an incipient character, requiring a greater incentive on the part of the respective courses.

The implementation of digital technologies in teaching has demonstrated the importance of teacher digital competence (TDC) as a key element in educating 21st-century citizens. The complex nature of TDC makes it challenging to find a definition that encompasses the full meaning of the term. This paper offers a systematic literature review based on the PRISMA Statement, analyzing the definitions of TDC in 31 publications with the aim of identifying their similarities and differences and reviewing their relationship with the dimensions that make up TDC. The results show an imbalance in the dimensions present, and notably, an almost universal absence of the relational, ethical and security dimension. The paper concludes by offering an integrative definition of TDC that enables teachers and educational institutions to understand the scope of this professional competence.
