INTERNATIONAL FEDERATION OF PHYSICAL EDUCATION AND ITS IMPACT TO MONITORING OF QUALITY PHYSICAL EDUCATION IN THE WORLD
Authors: Branislav ANTALA , Sergi Ivashchenko , Georgiy Lopatenko
Published: February 2021

Introduction. Physical activity is already well established in all Member States of
the EU in the form of physical education as well as various programmes to enable
young people to be physically active before, during and after the school day.
Nevertheless, active school breaks and inclusion of physical activity into school lessons
could be extended at national level. The number of hours of physical education is often
defined subnationally and in some instances by schools. Increasing the number of
mandatory hours and setting standards to ensure quality could further help students to
reach the WHO recommendations and ensure the potential of schools for promoting
physical activity among young people.
The study aimed to find out the best practices of the International Federation of
Physical Education to monitoring of quality physical education.
Material and methods: theoretical analysis and generalization of literary sources.
Results. Physical activity of youth can be increased in several ways. The most
broadly used practice is physical education, which is part of the school curriculum in
all EU Member States; however, the number of hours of physical education provided,
whether compulsory or optional, and the quality vary widely among countries. In order
to provide good quality, regular physical education and promote safe physical activity
to all young people in schools, physical education teachers must be adequately trained
in promoting health-enhancing physical activity, in addition to traditional sports.
Conclusions. It needs to be viewed in the context of inter-related strategies to
embrace the formulation and development of inclusive and equitable curricula, which
provide personally meaningful and socially and culturally relevant experiences and
which attract young people to the joy and pleasure of physical activity so as to foster
an active healthy lifestyle over the full life-span. Quality physical education curricula
need to be based on the vision that the knowledge, skills and understanding acquired
facilitate attainment of physical literacy and be part of a well-structured physical
education programme spanning from early childhood education to the upper secondary
level.
Office Clutter: Comparing Lower and Upper-Level Employees on Work-related Criteria
Authors:   DePaul University.
Published: February 2021

Office clutter might significantly impact productivity, yet no study examined workers differences across upper and lower employee status. The present study surveyed 202 U.S. on-site workers on work-related variables, including office clutter. Job classifications were aggregated, creating two groups: upper- and lower-level employees. A significant difference in office clutter impacted worker-levels: upper-level workers compared to lower-level workers had higher office clutter scores. Exploratory factor analysis created a two-factor solution (explaining 62.6% of the common variance): satisfaction/pleasure from one’s work and risk for work-related burnout/tension. There was a significant difference in office clutter perception: upper-level workers were significantly more likely to report clutter and being at risk for burnout/tension than lower-level workers. Office clutter significantly negatively predicted satisfaction with one’s job and positively related with risk for work-related burnout. Frequently reported office clutter items (in order of frequency) were paper, trash (e.g., used coffee cups), and office supplies.

THE PROCESS OF EDUCATION IN THE FIELD AND TEACHER FORMATION IN BRAZIL
Authors: Fagundes Maurício , Hoeller Silvana Cassia
Published: February 2021

This article aims to discuss the training of teachers for field education, referenced in the historical-political process that began at the end of the Brazilian military dictatorship. With the process of democratization experienced in Brazil since the mid-1980s, with the end of the military dictatorship, we highlight the transition from rural education to education in the field and the respective training of teachers to meet this specific demand. This process was made up of a public policy, the fruit of the mobilization of social movements. The need for teacher training gave rise to the graduation courses in Field Education, which work primarily with subjects who are inserted in the reality of the field, through the pedagogy of alternation and itinerancy. The methodology that contributes to this work is of a qualitative nature, developed through bilbiographical research, with a temporal cut from 1985 to 2018. As a conclusion, it is possible to point out that the degrees in Education in the Field, currently, are a reality as an educational process, which meets the specificities of the subjects in the field, reinforcing their identities and contemplating the specificities in several Brazilian regions, thus moving towards overcoming the existing conservative education and named as rural.

THE CROAT-BOSNIAK WAR: THE SELECT FINDINGS OF THE RECENT REGIONAL HISTORIOGRAPHY
Authors: Milašinović Arsen
Published: February 2021

The Croat-Bosniak war is one of the least researched episodes of the Bosnian war. I reviewed the recent works of two regional authors who had access to original war records of the Bosnian Croats and the Bosniaks and then compared their findings with some of the representative views of secondary literature. Among other things, I focused on the Vance-Owen peace plan and the initial hostilities in the central Bosnian municipalities. My chief conclusion is that the importance placed on the Vance-Owen peace plan in secondary literature is misleading as it ignores the local military and political dynamics.

Bertrand Russell: ateísmo, agnosticismo e filosofia analítica no século XX
Authors: Silva Ricardo Oliveira da
Published: February 2021

Este trabalho apresenta o surgimento e o significado do “ateísmo público” e do “agnosticismo filosófico” do inglês Bertrand Russell (1872-1970) a partir dos textos que ele produziu particularmente na década de 1890 e de 1920. Para realizar esse objetivo, optei por destacar no artigo: 1) o debate historiográfico sobre a identificação do autor como ateu e agnóstico; 2) as origens de sua descrença religiosa no cenário filosófico inglês da década de 1890 e as críticas que direcionou às doutrinas e instituições religiosas nos anos 1920; 3) avaliações sobre o ateísmo e o agnosticismo do pensador britânico. Com base nestes pontos, espero evidenciar a contribuição desse filósofo para a história das ideias sobre ateísmo e agnosticismo.
Forensic Environmental Examinations in Cases on Compensation for Harm (Damage) Caused by Environmental Violations: Analysis of Arbitration Courts’ Practice
Authors: Mikhaleva N. V.
Published: February 2021

The article analyses arbitration courts’ practice on the assignment of forensic environmental investigations on cases concerning the compensation for environmental damage caused by various environmental violations. At present, such investigations are assigned quite often. However, in most cases, private experts conduct them since there are very few state environmental experts. The article addresses examples of forensic environmental investigations for particular cases: on the facts of discharge of wastewater and oil products into water bodies, deforestation. It is shown that when determining the amount of harm (damage), non-state experts rely on the methods of calculating approved by the Ministry of natural resources and ecology of the Russian Federation, although many experts point out the shortcomings of these methods. In contrast, the Ministry of Justice system’s environmental experts determine the cost of restoration for specific violated environmental objects.
Quality Assessment and Identification of Fingerprints by Analysis of the Image’s Structural Properties
Authors: Asatryan D. G.
Published: February 2021

The paper addresses the problem of assessing the quality of fingerprint images using spatial analysis methods. The author proposes using the previously developed mathematical model to describe the set of magnitudes of the image gradient. The model is based on the two-parameter Weibull distribution. The author proposes two approaches to assess the quality of fingerprints. The first approach is implemented by the so-called “Full reference method”, which compares the Weibull distribution parameters’ values of statistical estimates. The results of identifying sweat pores using this method are presented. The second approach is called the “No-Reference method” and is used to assess fingerprints’ quality when analyzing and identifying the information content of their individual sections. It is proposed to use an image blur map as a quality characteristic and a statistical estimate of the Weibull distribution shape parameter as a measure of the blur. The shape parameter is estimated at each image point by the combination of magnitudes of the image gradient in the vicinity of the point; in this, the previously developed blur mapping technique is applied. The specific examples illustrate effectiveness of the proposed approaches.

Published: February 2021

The purpose of the research is to analyze the general scientific category of a trace as the fundamental one to formulate the modern legal category of a forensically relevant trace. The article provides a brief review of the views of scientists who have studied the properties of the general scientific category of a trace. The general scientific category of a trace is presented as a characteristic describing and explaining a trace’s properties. The author emphasizes the necessity to distinguish real and existing traces-signs from traces-ideas. The so-called ideal traces are analyzed. The article provides the classification of such traces. The classification recognizes the traces of memory as the traces of memorization, traces of storage and traces of recollection, and mental traces. It is suggested to pay attention to electronic data traces, virtual data traces, and digital data traces.

Authors: ÖZKURKUDİS Mary Jane , BÜMEN Nilay
Published: February 2021

Action research was carried out in the preparatory program of a foundation university to examine the effectiveness of cartoon discussions in vocabulary acquisition. Students were shown cartoon videos based on the theme of the textbook unit and were asked to answer the guiding questions including the target vocabulary implicitly or explicitly. Students were divided into randomly selected groups and were asked to complete a task using the vocabulary acquired through the learning management system. The students (n=19) were given a pre-and post-test with words that they were supposed to learn during the eight-week process. The tests were assessed by three different teachers (the W-coefficient was found as .944 for inter-rater reliability) using a pre-prepared rubric by the researchers. To evaluate students’ perceptions, at the end of the process, students were given a questionnaire. Findings revealed that the post-test results of the students, who acquired vocabulary through cartoon discussion and practiced collaboratively through the learning management system, were significantly higher compared to their pre-test results.

In this research, the views of science and social studies teachers regarding teaching science subjects were aimed to determine. Case study, one of the qualitative research methods, was used in the study. The sample of the study consists of 26 teachers in total, of whom 13 are social studies teachers and 13 science teachers working in public schools in Antalya/Turkey in the academic year of 2018-2019. In order to determine the opinions of teachers, “Interview Form for Teaching of Science Related Topics” which is a semi-structured form consisting six open-ended questions was prepared, and the data collected through interviews were analysed using descriptive statistics. The results in general showed that the topic of “science”, which is a common ground for social studies and science courses, was stated by teachers, and it was found out that teachers of both branches did not hold any joint meetings or work in collaboration with each other.
Physiological, biochemical and genetic bases of amaranth (Amaranthus L.) breeding for food and feed purposes (a review)
Authors: Shcherban A. B.
Published: February 2021

The review gives an insight into amaranth, a very promising crop for the whole world. This crop has a long history dating back to the days of the Aztecs and Incas, for whom it was one of the most important crops, along with corn. However, unlike the latter, amaranth lost its nutritional value after being introduced into Europe. Only in the 20th century, largely thanks to Nikolai Vavilov, amaranth attracted great interest as a food and feed crop. Amaranth is a plant unique in its nutritional properties. It is characterized by a high content of protein saturated with essential amino acids, especially lysine, and a large number of bioactive compounds, such as vitamin C, amaranthine, rutin, carotenoids, etc. Of particular value is grain oil saturated with various lipid compounds: squalene, vitamin E, phytosterols, and fatty acids. These lipid compounds have a number of important properties from the point of view of functional nutrition: as natural antioxidants they bind free radicals, normalize lipid metabolism, and help to decrease blood cholesterol levels. The review focuses on genes that determine the content of the main, valuable biochemical components: squalene, vitamin C, and lysine. The genetic pathways that control the biosynthesis of these components have been studied in detail in various model plant objects. The presence of the complete genomic sequence of Amaranthus hypochondriacus L. makes it possible to identify orthologs of key biosynthetic genes. At the moment, only few genes in amaranth have been identified, including the squalene synthase (SQS) gene, the VTC2 ascorbic acid synthesis gene, and the key genes for lysine synthesis – AK and DHDPS. The article discusses the prospects and trends of marker-assisted selection of this crop as well as the difficulties of its systematization and genotyping, which have to be overcome to successfully solve plant breeding problems.

This paper presents the ability to use cheap adsorbent (corn leaf) for the removal of Malachite Green (MG) dye from its aqueous solution. A batch mode was used to study several factors, dye concentration (50-150) ppm, adsorbent dosage (0.5-2.5) g/L, contact time (1-4) day, pH (2-10), and temperature (30-60)   The results indicated that the removal efficiency increases with the increase of adsorbent dosage and contact time, while inversely proportional to the increase in pH and temperature. An SEM device characterized the adsorbent corn leaves. The adsorption's resulting data were in agreement with Freundlich isotherm according to the regression analysis, and the kinetics data followed pseudo-first-order kinetic with a correlation coefficient of 0.9309. The thermodynamic data show that the process is exothermic and reversible. The highest removal of MG was 91%, which gave proof that the corn leaves as adsorbent material have the capability of adsorbing the MG dye for aqueous solutions
Assessing the Moisture and Aging Susceptibility of Cold Mix Asphalt Concrete

Laboratory experience in Iraq with cold asphalt concrete mixtures is very limited. The design and use of cold mixed asphalt concrete had no technical requirements. In this study, two asphalt concrete mixtures used for the base course were prepared in the laboratory using conventional cold-mixing techniques to test cold asphalt mixture (CAM) against aging and moisture susceptibility. Cold asphalt mixtures specimens have been prepared in the lab with cutback and emulsion binders, different fillers, and curing times. Based on the Marshal test result, the cutback proportion was selected with the filler, also based on the Marshal test emulsion. The first mixture was medium setting cationic emulsion (MSCE) as a binder, hydrated lime, and ordinary portland cement as a filler (7.95% MSCE + 2%HL + 3% OPC). The second mixture used was medium curing cutback (MC-250) as a binder and ordinary portland cement as a filler (5.18% MC 250 + 5% OPC). The indirect tensile strength (ITS) of the samples was measured at 25 ° C. It was found that the cold mix with the MSCE binder had a high ITS value relative to the cold mix with the cutback asphalt binder (MC-250). The dry mixture of MSCE  ITS was approximately 3.77 times the dry mixture of MC-250. The MSCE wet mix was about 4.2 times the wet MC-250 mix. Tensile strength ratio result (TSR %) for the MSCE binder mix and the cutback MC-250 binder mix showed that the MSCE mix has a reasonable moisture resistance (77% ) compared to the MC-250 mix (69.2 %). The aging test and aging ratio result showed that asphalt binder oxidation has a significant effect on age-related pavement degradation as it changes the time-temperature relationship depending on the viscoelastic properties of the asphalt binder. The result clearly showed that the MSCE binder mix had a high resistance to aging (440 Kpa) compared to the cutback (MC-250) binder mix (110 Kpa). In contrast, the MSCE aging ratio (90 %) was higher than the MC-250 ratio (85 %).

Published: February 2021

The construction sector consumes large amounts of energy during the lifetime of a building. This consumption starts with manufacturing and transferring building materials to the sites and demolishing this building after a long time of occupying it. The topic of energy conservation and finding the solution inside the building spaces become an important and urgent necessity. It is known that the roof is exposed to a high amount of thermal loads compared to other elements in a building envelope, so this needs some solutions and treatments to control the flow of the heat through them. These solutions and treatments may be achieved by using nanomaterials. Recently, nanomaterials have high properties, so that this made them good elements to the strategy of energy conservation in the architectural field. Accordingly, the research problem lay in "the lack of studies that deal with strategies to use nanomaterials in the roof of the building (especially the administrative building) in order to achieve energy conservation within its spaces". Then the research aims to: "Determine the efficient of nanomaterials in the roof to improving the thermal performance and achieving energy conservation in the indoor environment of the buildings in Iraq". This research's theoretical aspect has focused on using nanomaterial and their applications in roof systems. While in the experimental aspect, an administrative application to test a mass of identical administrates building in the design. In this research, simulation of the standard roof with nanomaterial, cool roof, and standard roof systems has been done using the Ecotect program. The results obtained in this research showed that the nanomaterial affected the thermal performance and achieved the indoor environment's quality by reducing to energy-consuming in the administrative building in the hot-dry climate of Iraq.
