Authors: Azmi Khairil
Published: September 2023

This Classroom Action Research was conducted by applying the Cooperative Learning Model Type NHT (Numbered Head Together) in order to improve the quality of the learning process and is a concept of learning activities that assist teachers in carrying out Integrated Science learning activities that are taught by trying to maximize the active role of students, especially their knowledge. and how to apply it in everyday life. With this concept, learning outcomes are expected to be more meaningful for students. The learning process takes place naturally in the form of student activities working and experiencing, not transferring knowledge from teacher to student. The quality of learning is important. This Classroom Action Research (CAR) was conducted with the aim of knowing the improvement of Integrated Science learning outcomes through the application of the NHT (Numbered Head Together) type of cooperative learning model in class VIII.7 students in the 2020/2021 academic year. This Classroom Action Research (CAR) was carried out in stages 2 cycles, and from the results of the actions that have been carried out it has been proven to improve student learning outcomes both in terms of classical student learning completeness, namely in the first cycle by 70%, it can increase to 93% in the second cycle. This means that there is an increase of 23% and in terms of the average value of the evaluation results, namely in the first cycle of 71 to 77.5 in the second cycle, this means that there is an increase. From the results of this classroom action research, it also shows an increase in the level of student learning activity from the Moderately Active category in the first cycle to the Active category.

The “17-year odyssey” outlines the research-to-practice pipeline that begins with setting priorities for funding research, publishing and peer review, research synthesis, developing guidelines for evidence-based practice, then finally as applied practice. Few studies have focused on the implementation gap within oral health domain. In this report, AIDPH outlines barriers within the dental peer-reviewed publication process that slow the translation of research to clinical implementation while offering strategic recommendations to expedite this pipeline. Using a multi-method research approach, this publication illustrates the role of peer-reviewed publications in the oral health translation process. Strategic recommendations include: 1. Evaluate opportunities to reduce funding barriers. 2. Broaden access to peer-reviewed information 3. Increase funding for and publication of replication studies 4. Explore innovative technologies in clinical settings

THE ATTITUDE OF TEACHERS OF ADDITIONAL MUSIC EDUCATION TO INCLUSIVE EDUCATION OF BLIND AND VISUALLY IMPAIRED CHILDREN
Authors:   Immanuel Kant Baltic Federal University, Simaeva Irina N. , Churkin Alexander I. ,   Immanuel Kant Baltic Federal University
Published: September 2023

The article presents the results of an empirical study of conditions and factors in assessing the prospects of inclusive additional music education for blind and visually impaired children. The positive attitude of experienced and highly qualified music teachers to the prospects of wider introduction of inclusive practice in music additional education programs, a humane attitude towards children with special educational needs, a positive assessment of the prospects for creating special conditions for special children in children’s art schools and children’s music schools was revealed. The authors share their expert opinion on the need for additional research on the issues of inclusive music admission education and the development of criteria for admission of children with disabilities to it. A significant part of experts express their concerns regarding the provision of inclusive practice due to the lack of experience working with special children and the necessary competencies. The community of teachers of additional education request some adapted methodological support for teaching performing arts to children with different types of disabilities, taking into account both the special educational needs of such children and the specifics of musical instruments. The problems are identified and tasks are set to ensure inclusive additional music education.

Em pediatria, há necessidade de reconhecer o desenvolvimento infantil como processo de formação, transacional e determinante na formação do adulto. A abordagem terapêutica em pacientes neonatais e pediátricos é diferenciada, ocorre muitas vezes sem testes clínicos adequados, e sempre deve buscar a promoção do conhecimento. Para assegurarmos a qualidade e garantia do atendimento à saúde infantil os serviços pediátricos devem ser responsivos, inovadores e com o máximo de segurança. Este conhecimento é fruto da troca dos saberes, das constantes atualizações dos profissionais, do conhecimento epidemiológico e da prática clínica quando bem executada. Parte dos profissionais de saúde se sente inadequadamente treinado para atender a este público em particular, o que gera justificável insegurança nos pais, pacientes e também nos próprios profissionais. O estudo das experiências profissionais, relatos de caso, revisões bem fundamentadas entre outros estudos possibilidade base para formação dos profissionais que desejam trabalhar com pediatria. Portanto, a Editora Pasteur criou uma coletânea para fornecer um campo rico de conhecimento. Este projeto foi possível devido à participação de profissionais e estudantes da área da saúde empenhados em fornecer o melhor material possível aos seus leitores.

When methyl manganese pentacarbonyl is treated with carbon monoxide in

This classic experiment conducted by Cotton (of quadruple bond fame) and Calderazzo in 1962[cite]10.1021/ic50001a008[/cite] dates from an era when chemists conducted extensive kinetic analyses to back up any mechanistic speculations. Their suggested transition state is outlined below.

The potential energy surface for a molecule tells us about how it might react. These surfaces have been charted for thousands of reactions using quantum mechanics, and their basic features are thought to be well understood. Coming across an entirely new feature is rare. So what do you make of the following? The reaction is shown above[cite]10.1039/P19920001709 [/cite], and on the face of it, it looks like a normal pericyclic cascade.

Dietary interventions through supplementation with antioxidant compounds
Authors: Todorović Vanja , Đorđević Brižita
Published: September 2023

Dietary supplements (DS) are manufactured products consisting of one or more dietary ingredients; they are intended to supplement the diet and provide additional nutrients or other beneficial compounds that are lacking or insufficient in a regular diet. Dietary supplements containing antioxidant compounds have been shown to have positive effects in various (pato)physiological processes, i.e., any condition that is fundamentally redox imbalanced (cardiovascular diseases, cancer, aging, intense exercise). The most common antioxidants in dietary supplements are clearly antioxidant micronutrients such as vitamin C, vitamin E, zinc, and selenium, but also various secondary plant compounds, including polyphenols and carotenoids. The dosage of antioxidants administered through dietary supplements may not always be optimal, so some dietary interventions through supplementation with antioxidant compounds have been shown to have an effect that it is limited, or completely absent. Therefore, any dietary supplementation should be done only under appropriate guidance from health care professionals to ensure that it is safe, effective, and appropriate for the individual's condition and needs.
The association between quality of life and the level of vitamin D in benign prostate hyperplasia
Authors: Kovačević Rada , Peličić Damir , Vojinović Tanja
Published: September 2023

Introduction: Epidemiological studies have suggested an association between vitamin D deficiency and benign prostatic hyperplasia (BPH). The prevalence of vitamin D deficiency in the male population with urological symptoms suggests a relationship between BPH and vitamin D. Methods: This paper will present information from relevant professional/scientific sources regarding the correlation of vitamin D levels with symptom intensity and quality of life of patients with BPH, as well as patient education and health care. Topic: The incidence of BPH is increasing with ageto such extent that it is unusual to find a histologically normal prostate in a man over 70 years of age, thus rising a question whether it should be considered an abnormality at all. From the beginning, the disease was classified as "the agony of the aged man" because benign gland enlargement carries a significant risk of morbidity due to urinary flow obstruction. Due to the long course of benign prostate hyperplasia, which significantly affects the quality of life and quality of sleep, the mental pressure in patients increases, resulting from both physical and mental pain. Therefore, the priority is to focus on medical measures which would improve the quality of life of elderly patients with BPH. Conclusion: After reviewing the literature, we came to the conclusion that the level of vitamin D is responsible for the quality of life of patients with benign prostatic hyperplasia. Health care integration emphasizes the integration of existing resources within the overall health policy planning, and professionally trained medical staff provides medical treatment, rehabilitation, home care, psychological counseling and hospital care for elderly patients with chronic diseases and semi-disabled, disabled and oncological patients.
The Cyrillic and Serbian culture
Authors: Tanasić Sreto
Published: September 2023

The paper speaks about the place and importance of the Serbian Cyrillic in Serbian culture. The Cyrillic with the Serbian language is undoubtedly among the most important identity signs, which proves that it is also necessary to assign such importance to it when devising national and cultural policies. It is exactly due to such identity importance that the Cyrillic was suppressed from the Serbian nation in the past and it continued in the 20th century, especially after the Second World War. Even today, after the breakup of the Serbian-Croatian language unity, many powers have an organized way of trying to prevent the return of the Cyrillic to its place. That speaks about its importance for the Serbian cultural and national identity.
Analysis of voluntary pension funds in Serbia in 2022
Authors: Radojković Ivan
Published: September 2023

The topic of this paper is the analysis of voluntary pension funds in Serbia in 2022 with the emphasis on the return rate. Introduction of private voluntary pension funds together with the state pension fund is the essence of the pension system reform, and that reform process began in 2005. Generally accepted pension system is a three-pillar system, but introduction of the second pension pillar in our country will not happen anytime soon, and the question is whether it will be introduced at all. The third pillar of the pension system is voluntary and this is its greatest advantage. Voluntary pension system consists of three interconnected processes: payments to the voluntary pension fund, investment of free funds, and programmed payments - pensions. In order to form a valid investment portfolio and achieve a long-term and good return from investments there must be a stable inflow into voluntary pension funds.
Biofuels as a challenge of sustainable development

Published: September 2023

Bioenergy, or energy derived from biomass, today is recognized as an important component in many energy scenarios, being an integral part of various global, regional, and national policies and strategies. This has led to intensified research into more efficient biofuel production. This paper explains the advantages, disadvantages, and problems related to the production of biofuels from different types of raw materials. Several examples of commercialized and demonstration plants for the production of biofuels in different parts of the world are listed. It is to be expected that, with greater use of modern biofuel production solutions, the contribution of these sources of (bio)energy will be the main part of future energy consumption from renewable sources.

Analysis of stopping behaviour of cyclists at a traffic light-controlled intersection using trajectory data
Authors: Leschik Claudia , Zhang Meng , Gimm Kay
Published: September 2023

Cyclists have various route options to get to their destination. They can share lanes with vehicles, share lanes with pedestrians, or have their own lane. In Germany there are often marked lanes across intersections and stop lines in front of the crossing, guiding the cyclists their way. However, these markings are not always respected in the way they should be.

This study is intended to examine the stopping behaviour of cyclists at a traffic light-controlled intersection. A distinction was made between cyclists riding alone (n = 1,411) and cyclists riding in groups (more than one cyclist; n = 475). The stopping area was divided into polygons to understand where most people stop before an intersection. Furthermore, it was examined where people continued to ride after stopping (path marked for cyclists or path marked for pedestrians) and this was compared with cyclists who did not stop.

The aim of this study is to investigate cyclists’ stopping behaviour (e.g. stopping position) at intersections with consideration of the impact of groups, wrong-way riding and road usage. It is to be investigated whether cyclists alone behave differently than cyclists in groups and whether there are differences in the two groups for wrong way cyclists. Both - cyclists alone (69.38%) and cyclists in groups (84.57%) - crossed the intersection more frequently without stopping within the observation period. In all cases, cyclists stopped more often at the bicycle stopping line or used the special marked bicycle lane, thereby complying with the law. Most wrong way cyclists on the special marked bicycle lane were found for cyclists alone with stopping (10%, n = 27) and cyclists in groups with stopping (8%, n = 12). The speeds were also compared. The speeds between cyclists alone and cyclists in groups differ slightly, and the stopping behaviour is very similar if the special marked bicycle lane is used after the stop.

The information can be used to improve models of cyclists’ behaviour, for example in microscopic simulations, in which cyclists only stop at clearly defined locations. Furthermore, the results of this study will provide further knowledge, which help developing autonomous driving functions correctly anticipating cycle behaviour at intersections.

A influência husserliana na ética material de Max Scheler
Authors: Aparecida Bello Borges Luiza
Published: September 2023

O presente artigo tem o objetivo de apresentar a fundamentação da possibilidade de intuição dos valores na ética material de Max Scheler, salientando as influências sofridas pela proposta fenomenológica de Edmund Husserl. Destacam-se a intencionalidade da consciência, objeto de desenvolvimento de Husserl na obra Ideen zu einer reinen Phänomenologie und phänomenologischen Philosophie (1913); e as investigações fenomenológicas presentes na Logische Untersuchungen (1901). Segundo Husserl, na relação fenomenológica da consciência intencional com o mundo, o ser humano intui os universais que são a priori, necessários e transcendentes através da intuição categorial. É essa consciência intencional que, na dimensão prática, intui os valores através da concepção scheleriana da intuição emocional. Assim, os valores também são a priori, universais, necessários e transcendentes. A discussão sobre a possibilidade de conhecimento dos valores em Scheler, portanto, perpassa também a problemática sobre a possibilidade de conhecimento dos universais trazida por Husserl. O desenvolvimento da pesquisa se dá na forma de investigação filosófica em que se define um objeto identificável, o estudo comparativo entre as propostas fenomenológicas husserliana e scheleriana a partir da abordagem dos universais.
Educar a educadores sobre temas de raza y desigualdad: conciencia crítica, desafíos y cambios generados.

Published: September 2023

Introducción: Los docentes como parte de la comunidad educativa y con base a los cambios que se van generando a nivel mundial y regional deben hacer frente a diversas situaciones que van más allá del nivel de preparación profesional para ser maestros, Objetivo: Descubrir la desigualdad racial dentro del del contexto educativo a nivel de Latinoamérica y particularmente de Ecuador, esto desde la perspectiva de educar a educadores sobre esta temática, descubriendo de esta manera la conciencia crítica, los desafíos y cambios generados.. Metodología: El tema que se abordó en el presente artículo de revisión sistemática; en cuanto, al alcance aplicado al presente análisis, se determinó que sería de tipo descriptivo y explicativo, la modalidad de la investigación fue exclusivamente documental, lo que respecta al enfoque del estudio, se determinó la aplicación del cualitativo. Resultados: Si bien las investigaciones han documentado sistemáticamente la discriminación en poblaciones de minorías raciales y étnicas, se sabe mucho menos sobre fuentes específicas de discriminación, como las que se producen en diversos entornos y que son perpetradas por diversos perpetradores. Conclusiones: Aunque es probable que estas experiencias discriminatorias sean experimentadas tanto por niños como por niñas, los hallazgos a partir de la revisión sistemática, permitieron determinar que estos comportamientos son manifestados bajo consciencia, así como a partir de los resultados de aquellos artículos sugieren desde una perspectiva interseccional, que estas experiencias pueden ser más perjudiciales para estudiantes de grupos sociales minoritarios

Introduction: Cognitive composite scales constructed by combining existing neuropsychometric tests are seeing wide application as endpoints for clinical trials and cohort studies of Alzheimer’s disease (AD) predementia conditions. Preclinical Alzheimer’s Cognitive Composite (PACC) scales are composite scores calculated as the sum of the component test scores weighted by the reciprocal of their standard deviations at the baseline visit. Reciprocal standard deviation is an arbitrary weighting in this context, and may be an inefficient utilization of the data contained in the component measures. Mathematically derived optimal composite weighting is a promising alternative. Methods: Sample size projections using standard power calculation formulas were used to describe the relative performance of component measures and their composites when used as endpoints for clinical trials. Power calculations were informed by (n=1,333) amnestic mild cognitive impaired participants in the National Alzheimer’s Coordinating Center (NACC) Uniform Data Set. Results: A composite constructed using PACC reciprocal standard deviation weighting was both less sensitive to change than one of its component measures and less sensitive to change than its optimally weighted counterpart. In standard sample size calculations informed by NACC data, a clinical trial using the PACC weighting would require 38% more subjects than a composite calculated using optimal weighting. Discussion: These findings illustrate how reciprocal standard deviation weighting can result in inefficient cognitive composites, and underscore the importance of component weights to the performance of composite scales. In the future, optimal weighting parameters informed by accumulating clinical trial data may improve the efficiency of clinical trials in AD.
El cuidado de sí y la estética de la existencia: prácticas para reflexionar en torno a la educación. Una aproximación desde Michel Foucault.
Authors: Vargas Serafin Andi Alberto
Published: September 2023

Para Michel Foucault, la constitución del sujeto representa un eje nodal en sus análisis, a tal punto que inquirir por la manera en cómo devenimos sujetos, se convierte en una pregunta por nosotros mismos, es decir, por quienes somos o quienes hemos llegado a ser; ahora bien, considerando que la educación es un aspecto esencial en la vida de todo ser humano, la cual no se subsume a un aspecto o a una institución, el presente escrito tiene como premisa posicionar el carácter subjetivante del cuidado de sí y la estética de la existencia para acentuar su preponderancia en la acción educativa y formativa del individuo, es decir, poner de relieve que éstas no son meramente nociones teóricas sino que se revelan como prácticas significativas para la pedagogía en tanto que amplían no solo el desarrollo de ésta hacia nuevas consideraciones o principios educativos, sino que también amplían la formación del estudiante, tanto en lo que respecta a determinados aspectos intelectuales, como también en lo relativo a diversos aspectos éticos y estéticos, todo lo cual se traduce en la consolidación de nuevas relaciones humanas.
