Desempenho térmico de blocos de vedação sustentáveis, compos-tos de argamassa de cimento e areia e insertos de garrafas PET preenchidas com cinza da casca de arroz
Authors: Bitencourt das Neves Everton Luis
Published: December 2020

Os impactos negativos causados pela construção civil ao meio ambiente são preocupações crescentes. Tais fatos têm levado ao desenvolvimento de pesquisas que buscam novas fontes de matérias-primas a partir do uso de resíduos oriundos de materiais descartados na natureza. Dentre os resíduos, destacam-se a cinza de casca de arroz (CCA), que é gerada após a queima da casca de arroz para a produção de calor e energia, e as garrafas PET que, em detrimento de sua já comprovada reciclabilidade, ainda representam um perigo ao meio ambiente devido o descarte inadequado. Visando solução para os problemas ambientais provocados por esses resíduos, apresenta-se nesse trabalho o processo de obtenção de blocos de argamassa de cimento e areia, garrafas PET e CCA e a sua caracterização quanto ao desempenho térmico, visando a sua utilização na construção civil. Para a obtenção dos blocos, foram analisadas três composições: a primeira, usada como referência, constituiu-se de argamassa de cimento e areia; a segunda de argamassa de cimento e areia e a inserção de garrafas PET preenchidas com CCA; e a terceira de argamassa de cimento e areia e a inserção de garrafas PET vazias. A argamassa utilizada foi caracterizada quanto a resistência mecânica à compressão e os blocos obtidos foram caracterizados quanto a densidade de massa aparente e à condutividade térmica. A determinação da condutividade térmica foi feita de forma análoga ao método das placas quentes protegidas. Os resultados mostraram que os blocos de cimento e areia com insertos de garrafas PET preenchidas com CCA apresentaram redução de 28% na condutividade térmica em comparação ao bloco maciço de argamassa de cimento e areia usado como referência.

New forms of employment and workers' health
Authors: Denisov Eduard I.
Published: December 2020

Globalization and digitalization give rise to a complex of problems of economics, sociology, and occupational health. The prevalence of precarious employment (PE) is growing. In connection with the COVID-19 pandemic and the economic crisis, employment and social well-being have become acute. The study aims to review literature and essays on PE as a problem of occupational health and a new social determinant of workers' health. The author has made the analysis of documents from WHO, ILO, European Union, etc., scientific literature and essays on the problem of PE and its impact on somatic (including reproductive) health, mental health, and workers' social well-being. The legal bases of labor and health protection are considered. The informal economy, the terminology of forms of PE, and the ILO Convention No. 175 on part-time work and the Convention No. 177 on home work and the Decent Work Initiative were analyzed. The characteristics and prevalence of PE, examples of forms of work organization, affected groups of the population, and sectors of the economy are considered. Vulnerable groups are women (especially pregnant women), young and elderly workers, migrants, and the most unfavorable situation is in construction, agriculture, catering, tourism, etc., and much better in the public sector. PE and its impact on health are an essential topic in social epidemiology, and affective health problems are almost as severe as unemployment. PE is often associated with poor working conditions, physically demanding work and an increased risk of accidents, with young workers more often affected. The lack of confidence in keeping a job negatively affects mental health - the odds ratio is over 1.5. PE is associated with impaired reproductive behavior and reproductive health and the birth of children with low body weight. The features of home work, its pros, and cons are given. An analysis of employment from the standpoint of occupational health revealed the relationship between forms of employment and indicators of health and quality of life and made it possible to complete some generalizations and formulate the principles of work and health. The future of labor, new occupations, knowledge, and skills are considered. In the United Nations Development Program, Goal 8, Decent Work and Economic Growth, is to achieve full employment and decent work for all by 2030. PE is becoming more frequent; therefore, further data collection and research into its effects among new groups of workers is necessary. Soon, the digitalization of the economy and society will cause a paradigm shift in occupational health: the future of occupational health is the prevention of occupational diseases and work-related disorders.

Published: December 2020

Modern trends in the deterioration of health and the growth of non-communicable diseases among the adult working-age population, including medical workers, actualize the importance of a healthy lifestyle for maintaining health and professional longevity. There were almost no studies related to cosmetologists' experienced group as representatives of aesthetic medicine. There is no scientific evidence on behavioral risks of this group. It justifies the relevance of this study. The study aims to analyze the essential components of the cosmetologists' lifestyle depending on age and the argumentation of priority behavioral health risk factors for preventive and recreational work justification. Sixty women (practicing cosmetologists in Volgograd at the age of 28-39 years (group A) and 40-53 (group B)) took part in the study. Lifestyle assessment included a modified questionnaire. The questionnaire consists of 5 blocks (block 1 - nutrition; 2 - physical activity, including hardening and active rest; 3 - daily regimen; 4 - personal hygiene; 5 - bad habits). It allows the analysis of the adherence to a healthy lifestyle based on the provision of quantitative data. Statistical data processing was carried out using the Excel package. The authors identified the essential and statistically significant differences in the cosmetologists' lifestyle depending on age. The respondents of group B demonstrated hygienically rational indicators in all blocks of the lifestyle more often. They had a more formed adherence to a healthy lifestyle: 504 answers in the category "insignificant risk" of respondents in group B versus 354 in group A. Distribution of answers in the "high risk" category: 119 responses in group B and 185 in group A. The lifestyle of 46.7% of the respondents in group B refers to a healthy lifestyle. 3.3% of the group B respondents have an anxious lifestyle, 50% have health risks. 10% of Group A respondents' lifestyle refers to a healthy lifestyle. 13.3% of Group A respondents' lifestyle refers to an anxious lifestyle; 76.7% of this group have health risks. There was almost no complex hygienic research profession of medical cosmetologists. Cosmetologists of the older age group (40-53 years old) are more conscious of maintaining a hygienically rational lifestyle. The most significant defects among cosmetologists aged 28-39 years are low physical activity, nutritional defects, insufficient duration of night rest, and excessive use of information and communication technologies for rest, accompanied by manifestations of neurotization and signs of pronounced fatigue. The obtained results argue the need to develop and implement informational and educational measures to prevent risk behavior patterns, taking into account the age of cosmetologists and the priority of the identified behavioral risk factors.

Authors: Prikhodko K. S. , Mitrakova N. N. , Rozhentsov A. A. , Mitrakov A. A.
Published: December 2020

The purpose of the study: The main purpose of the study is creation of a system for digital processing of endoscopic images in white light and narrow band imaging for the early diagnosis of early forms of stomach cancer.

Materials and methods: The object of the study is endoscopic images (6320 cases) with PENTAX EG-2790K and OLYMPUS H180 devices. The subjects of the research are mathematical models of gastric epithelial neoplasias, classifi cation of these tissues, methods of digital image processing and contour analysis, methods of mathematical modeling.

Results: The work is divided into two stages to obtain quantitative estimates of the studied characteristics: 1. To make a diagnostic map — the image is segmented, then the boundaries between the pathologically altered tissues and the normal mucous membrane are drawn. 2. The calculation of the characteristics of the contour associated with diagnostic signs is made. As a measure of the symmetry of the figure, the symmetry coefficient k was used, defined as the ratio of the number of samples of the normalized autocorrelation function that exceeded the specified threshold in level to the total number of samples. The study revealed that the contours of malignant neoplasms have a symmetry coefficient k < 0,05, and the contours of benign neoplasms k > 0,2. This suggests the possibility of automated differentiation of neoplasms based on the analysis of their shape.

The conclusion: An objective assessment of endoscopic signs of early gastric cancer is necessary to standardize and systematize the diagnostic approach. The unified digital processing of endoscopic images will allow the endoscopist to increase the frequency of detecting early forms of gastric cancer, which will affect to reduce mortality.

Published: December 2020

Soybean is one of the most popular food crops for the community, but the needs for soybeans have not been fulfilled by soybean production. To meet the needs of soybeans, it is necessary to intensify agricultural land in Ultisol. This study aims to obtain the optimum concentration of humic acid and dosage of the Arbuscular Mycorrhizal Fungi (AMF) to increase soybean plants' production in Ultisols. This research was conducted from January to April 2020 in Beringin Raya Village, Muara Bangkahulu District, Bengkulu City, at an altitude of 10 m above sea level. The research design used a Randomized Complete Block Design (RCBD) two factors with three replications, arranged factorially in experimental units. The first factor is the concentration of humic acid, consisting of 4 levels: 0, 15, 30, and 45 mL L-1 . The second factor is the dose of AMF, consisted of 3 levels, namely: 0, 2.5, and 5 g plant-1. The results showed that the maximum soybean growth and yield in Ultisols were obtained from the humic acid concentration at 45 mL L-1 at the dose of AMF at 2.5 g plant-1 . The resulting production potential is 1.99 tons ha-1 . The administration of humic acid or AMF independently at this research stage had not yet given a maximum response to the growth and yield of soybean in Ultisol.

A Definite Explanation of the Concept of Limit in Teaching
Authors: Miyane Sunmi
Published: December 2020

The limit idea is the basic idea of calculus. Almost all concepts in mathematical analysis are inseparable from the limit, but the limit is a concept that is difficult to understand accurately. By assuming that there is a certain point closest to the limit value, this paper provides a reasonable explanation for the infinitesimal paradox and a new answer to the question why the limit value is accurate in teaching. At the same time, this method is applied to the derivative and used to understand a common practical problem in mathematics. The analysis shows that this method is effective for the accurate understanding of limit problems.

Territorialité, langue, toponymie et traité chez les Pekuakamiulnuatsh
Authors: Tipi Sükran , Boivin Hélène
Published: December 2020

La Première Nation des Pekuakamiulnuatsh (Innus du Lac Saint-Jean), est engagée dans un processus de négociation territoriale depuis plus de quarante ans. Elle travaille présentement avec ses partenaires du Regroupement Petapan en vue de finaliser un projet de traité avec les paliers de gouvernements fédéral et provincial, dans le cadre de la politique sur les revendications territoriales globales. Se situant toujours au fondement de l’affirmation identitaire des Pekuakamiulnuatsh, la notion de territoire demeure indissociable du lien entre langue et territoire, et de la manière dont celui-ci trouve son expression aujourd’hui dans leur langue, le nehlueun, entre autres par l’usage de toponymes, mais également dans les dispositions prévues au projet de traité préparant la voie à l’autonomie gouvernementale pour les générations futures. Le projet de recherche multidisciplinaire Peshunakun, initié par la Première Nation de Mashteuiatsh en 2008, en réponse à un besoin d’affirmation culturelle et politique, met en évidence l’ancrage même de l’identité et de la langue ilnu dans l’espace, à travers une démarche de documentation de l’histoire de l’occupation et de l’utilisation du territoire ancestral. Un éclairage nouveau est ainsi jeté sur la territorialité de cette Première Nation sous l’angle du lien entre leur langue, leurs visions et leurs préoccupations politiques actuelles.
Illuminating Details: Reflections on a Practice of Anthropology
Authors: Dyck Noel
Published: December 2020

This revised address for the 2019 Weaver-Tremblay Award revisits some underlying questions about the practice of anthropology that have figured in my own work. First, why might one choose anthropology as a means of intellectual and practical inquiry into social and cultural phenomena? Second, what kinds of anthropological practice can be pursued? Finally, what types of knowledge can be acquired through anthropological approaches, and to what purposes might this knowledge be applied? These questions are considered within the context of two rather different fields of anthropological inquiry I have pursued: relations between Indigenous Peoples and state governments, on the one hand, and the social construction of sport, on the other. As well as sharing some unexpected analytical commonalities, these ostensibly disparate fields speak to the power that resides in illuminating details of the type that anthropologists are particularly adept in recognizing.
IN EXTREMIS:Communal Expressions of Serious Impoverishment in the Dominions of the Kings of England, 1250–1450
Authors: Bothwell James
Published: December 2020

This article focuses on how communities in later medieval England claiming serious impoverishment articulated their plight to those they thought might be able to help through petitions to the king’s government. Using the 454 petitions, mainly in French, submitted to the king’s government between 1250 and 1450 citing substantial communal impoverishment, three main groups of petitioners are examined: secular communities, religious houses, and wider groupings of the population. While these petitions make up only a fraction of all surviving petitions from the later Middle Ages (2.59% of the 17,514 Special Collections 8 Ancient Petitions), they not only embody the most important communal requests for serious need to the king’s government from all such petitions but also represent a significant proportion of the populace as a whole and account for many of the most important communities under the English king’s control. Indeed by focusing on communities rather than individuals, a clearer sense should emerge of how medieval people understood, if not usually articulated, key aspects of their own common good in extremis — rather than how those with power defined it for them. Also by looking beyond England to those lands under the English monarch’s control from Ireland to southern France, we can see how communities on the very fringes of royal power viewed the English government’s role toward them. Overall this article illuminates how medieval communities claiming to be in or moving toward extreme need saw themselves and/or wanted others to see them, the reality of the situation where known, what petitioners thought was the best way forward, and the royal government’s reaction to such requests.
ПОСТРОЕНИЕ ПРОТОТИПА АВТОМАТИЗИРОВАННОЙ БЕСПРОВОДНОЙ СИСТЕМЫ МОНИТОРИНГА ЗАПЫЛЕННОСТИ ВОЗДУХА НА ПРОИЗВОДСТВЕННЫХ ПЛОЩАДКАХ

Published: December 2020

Разнообразные исследования последних десятилетий показали, что мелкие пылевые частицы могут представлять серьезную опасностью для здоровья, способствуя развитию  респираторных и сердечно-cосудистых заболеваний. Выявлены потенциальные связи между вероятностью возникновения таких заболеваний, как хроническая обструктивная болезнь легких (ХОБЛ), астма, рак легких, с концентрацией пыли в воздухе. Есть корреляционные данные, свидетельствующие о том, что при увеличении ПДК пыли в воздухе всего лишь на 50 мкг / м3, приводит к увеличению смертности на 1-8 %. Твердые пылевые частицы оказывают существенное влияние на жизнь растений и животных. Многие промышленные, экспериментальные и медицинские процессы могут быть безопасно осуществлены только при определённых значениях концентрации пылевых частиц в воздухе: например, пыль, состоящая из твердых частиц  размером менее 850 мкм, находящихся во взвешенном или осевшем состоянии в газовой среде, способна к самостоятельному горению и взрыву в воздухе. Такая пыль классифицируется как горючая пыль и, при определенных концентрациях, может стать причиной несчастных случаев на производствах, связанных со взрывами пылевоздушных смесей. Создание автоматизированной системы, способной контролировать запылённость воздуха в различных производственных помещениях является актуальной задачей. Данная работа посвящена созданию подобной системы, объединяющей в себя необходимое количество датчиков пыли, связанных между собой в беспроводную сеть, позволяющую управлять процессом измерения и фиксированием результатов измерения  каждого конкретного датчика.

Published: December 2020

The article considers the process of studying the correlation between the development of personal qualities, the level of physical training of students in universities and the attitude of students to physical education classes.
Physical education is one of the main ways of educating modern youth, which should harmoniously combine moral purity and spiritual wealth, physical perfection and psychological purposefulness. It has an impact on increasing the social and labor activity of students during their study at university. An active and healthy person keeps youth for a long time, continuing creative activities, not allowing “the soul to be lazy”.
Methods. To achieve the research purposes, we used a specially developed questionnaire on the impact of physical education on the health and attitudes of boys and girls to the subject.
The experiment was conducted on the basis of the Sevastopol State University. The sample of probationers from the 1st year of study were 205 students (100 boys and 105 girls).
The results of the study showed that 42% of the 1st year students chose to conduct physical education in the educational format, 37% of them are against compulsory classes, and 21% are neutral about physical education. Statistics showed that 60% attend classes only to get a «credit», 33% are interested in studying and gaining knowledge in their sport, and 7% do not attend classes well for various reasons.
The authors come to the conclusion that the requirements for graduates of educational institutions presuppose the development of new competencies by teachers that allow them to organize the educational process qualitatively and develop a positive attitude of students to physical education.
Pathogenicity of Gaeumannomyces Tritici (J. Walker) Hern.-Restr. & Crous, The Take-All Fungus and efficacy of Bacillus strains against disease
Authors:   National University of Life and Environmental Sciences of Ukraine, Kriuchkova L. O. , Olifer D. R. ,   National University of Life and Environmental Sciences of Ukraine
Published: December 2020

Isolates of Gaeumannomyces spp. obtained from diseased roots of winter wheat showing take-all symptoms were characterized by pathogenicity. All isolates were more pathogenic on wheat and barley than on oat, and were identified as Gaeumannomyces tritici. Most isolates of G. tritici were characterized as middle pathogenic, the pathogenicity of one isolate was higher than those of others, and two isolates showed the lowest pathogenicity. In growth chamber assay, the effect of two Bacillus strains, B. subtilis 16 and B. pumilus 11, on take-all of wheat was studied. Pathogen inoculation was made by isolates of G. tritici of different pathogenicity. It was found that effective biological control depends on take-all severity, which, in turn, co-ordinates with the pathogenicity of fungal isolate. Applying the bacterial cells into the plant growth substrate stimulated the seedling growth when artificial inoculation was performed with a middle pathogenic isolate of G. tritici, and the disease severity was middle. There was no growth promotion by bacterial inoculant at slight disease severity. No stimulating effect was also observed at the high disease severity, where pathogen inoculation was performed with a highly pathogenic isolate of G. tritici.

Published: December 2020

Study Design: Animal case control study.Purpose: To create a simple, reproducible disc degeneration model for mouse coccygeal vertebrae. Overview of Literature: Back pain due to disc degeneration is probably the most common problem encountered in neurosurgical practice. An easily reproducible animal model for disc degeneration will help in understanding its pathophysiology, and serve as a platform for examining various therapeutic options.Methods: A total of 18 mice were divided into injured (n=12) and non-injured (n=6) groups. The disc height index (DHI%) at coccygeal 4–5 level was measured by computed tomography (CT) scan for all mice. Coccygeal 4–5 discs of the injury group were injured using a 32G needle fixed to a novel tool and confirmed by CT. The non-injury group underwent no procedure. DHI% was measured by CT at 2-, 4-, and 6-week post-injury, and all mice tails were sectioned for histopathology grading of disc degeneration at the respective time intervals.Results: The injured group showed significant variation in DHI% at 2, 4, and 6 weeks, whereas there was no change in the noninjured group. Histopathologic evaluation with Safranin O stain showed a worsening of the disc degeneration score at 2, 4, and 6 weeks in the injured group, but in the non-injured group there was no change. Percutaneous needle injury technique with our novel tool provided 100% accuracy and uniform degeneration.Conclusions: A simple, easily reproducible mouse model for disc degeneration was created using a simple, cost-effective, novel tool and technique, its advantage being high precision and user friendly.

Published: December 2020

The article aims to explain Butonese women work ethics focusing on three factors, namely the development of work ethics, the aspects, and the challenges in developing their businesses. The research is a qualitative research with case study. The study is conducted in four villages in Luhu Hoamual District and West Seram District in Maluku Province, including Temi, Tapinalo, Mangge-mangge, and Eli. The informants were the Butonese women whose professions are traders. The methods used in this research are observation, interview and library research. The data analysis was done through reduction, presentation and concluding processes. This study found that the work ethic of Butonese women is not due to a religious calling as Weber said, but as a rational choice following Coleman ideas of surviving from the nature challenges, business opportunities, and family’s economic condition. In this process, two professions with different orientations were born. The pajibujibu sell their agricultural and plantation products from the west coast of Seram in Ambon city, meanwhile, the papalele sell fishery products on the west coast of Seram and the Hitu peninsula. If papalele is easy to get access to capital for business development, pajibujibu finds challenges to get it. Therefore, pajibujibu finds difficult to develop the business in compared to papalele. Nevertheless, both play important roles as actors in the economy of coastal communities.

Summary. The aim of the study was to determine peculiarities of the distribution, diagnosis and development of immune cytopenias in patients with chronic lymphocytic leukemia (CLL) and to evaluate the efficacy of the different therapeutic approaches. Materials and Methods: Treatment response and survival of 83 patients with CLL complicated by immune cytopenia (IC) were analyzed. Treatment schedules in 58 medicated patients included corticosteroids; chemotherapy (COP, CHOP regimens), immunotherapy (rituximab alone), immunochemotherapy (rituximab-containing regimens — R-COP, R-CHOP). Twenty-five patients underwent splenectomy. Results: The use of corticosteroids, as the first line of treatment, resulted in short-term remission in most patients. Chemotherapy was effective in a half of CLL patients, but duration of the remission did not exceed 32 months in CLL associated with autoimmune hemolytic anemia and immune thrombocytopenia. After rituximab monotherapy (10 patients) the stable remission was reached in 60% of the patients with median relapse-free survival of 40 months. Rituximab containing chemotherapy (22 patients) caused the long-term remission in 72% of the patients with median relapse-free survival of 76 months. Splenectomy performed in 25 patients with CLL complicated by IC was effective in 70% of the patients. The outcome of splenectomy depends on IC entity. The best response was registered in associated immune thrombocytopenia (median overall survival 118 months), the worst — in Fisher — Evans syndrome (15 months). Conclusions: The treatment of patients with CLL complicated by ICs should be individualized. For CLL patients without significant enlargement of lymph nodes and spleen, low lymphocytosis, associated with autoimmune hemolytic anemia or immune thrombocytopenia, the monotherapy with rituximab is optimal. In case of occurrence of autoimmune hemolytic anemia, immune thrombocytopenia or Fisher — Evans syndrome in CLL patients with enlargement of lymph nodes, spleen, significant lymphocytosis, the use of R-COP or R-CHOP schemes, 4–6 courses, is the most effective. Splenectomy is indicated in patients with massive splenomegaly, the resistance to medication, recurrent relapses after adequate therapy.

Opinions are personal judgment on entity. This is not only true for individuals but also true for organizations. Opinion mining is a type of natural language processing for tracking the mood of the public about a particular product. The process of sentiment mining involves categorizing an opinionated document into predefined categories such as positive, negative or neutral based on the sentiment terms that appear within the opinionated document. For this study text document corpus is prepared by the researcher encompassing different movies ‘reviews and Various techniques of text pre-processing including tokenization, normalization, stop word removal and stemming are used for this system(sentiment mining model for opinionated afaan Oromo texts). The experiment shows that the performance is on the average 0.849(84.9%) precision and 0.887(88.7%) recall. The challenging tasks in the study are handling synonymy and inability of the stemmer algorithm to all word variants, and ambiguity of words in the language. The performance the system can be increased if stemming algorithm is improved, standard test corpus is used, and thesaurus is used to handle polysemy and synonymy words in the language.

The construction industry in Nigeria faces many problems, including the delay due to variations in project execution. This delay has been studied as a major setback in the Nigerian construction industry. In Nigeria, the construction industry's performance in terms of time has been observed to be poor. The objective of this study is to examine the variation of the construction project in order to determine the effect on the delivery of the project. The maximum performance of the project would be reached if the work always goes efficiently on time with the budget. The result of the variation is delay, cost overruns, quality defects and other negative impacts. The causes of variation were identified by a questionnaire survey for two higher education institutions. The results of the study identified the five main factors, including change of plan or scope, defective labour, customers' financial problems, unavailability of skills and desired profitability of the entrepreneur. In general, the study shows agreement among clients, consultants and contractors regarding the classification of the 20 factors that cause the variation. The results also reveal that factors related to clients are the main causes of variation, followed by factors related to contractors. An understanding of the causes and effects of the variation would be helpful in training professionals to assess the variation. In addition, the study would also help professionals take proactive measures to reduce the gaps on construction projects.

El municipio de Porto Grande fue creado el 1 de mayo de 1992 y se encuentra en la región norte del estado de Amapá, con una superficie de 4 400 km2. El objetivo de este trabajo es realizar el análisis semicuántatario de una muestra de arena de Areal ubicada en el municipio de Porto Grande, la muestra recogida pasó por algunos pasos fundamentales como: secado, determinación de la humedad, determinación de fracciones de arcilla, limo y arena, homogeneización, quarteamento y análisis del tamaño de las partículas. En la determinación de la humedad obtuvimos el porcentaje del 2,4%, y esta fue la diferencia entre la masa húmeda y la masa seca de nuestra muestra P1, después del proceso de tamizado, el porcentaje del material retenido en cada tamiz se calculó para analizar el rendimiento de nuestro tamizado y finalmente se realizó la determinación de las fracciones de arcilla, que tenía como peso 0.17 g , limo con un peso de 24,83 g y arena de 275 g. Sin embargo, al final de las pruebas podemos observar una anomalía en los resultados del análisis del tamaño de partícula, debido al hecho de que el tamiz en cuestión estaría húmedo, evitando así el paso de todo el material de granulometría fina.

The research deals with the development of cognitive process dimensions in economic education. The aim is to research factors that influence academic achievement of students according to their intellectual level and grades. The researchers used quantitative design of research based on standardized assessment of intelligence and non-standardized questionnaire. The questionnaire was used to analyse the pedagogical competences of the teachers of economic subjects from the students' point of view in close relation to the teaching management and the impact on the motivation to learn and the achievement of students in these subjects. The respondents were 277 Czech students aged 16-17 who were divided into groups according to their intellectual level and grades. The data were analysed by a correlation analysis and a multiple regression model. In conclusion, the following can be stated: (a) From the point of view of the above average intelligent students, expertise can be considered as an important competency of the teacher; teaching average intelligent students, communication and presentation skills seem to be important. (b) It is desirable to develop cognitive processes, critical thinking actively, to lead students to become aware of changes in their own thinking and to orient them towards mastery goals. (c) Particularly for students with weaker results it is necessary to create intrinsic motivation, which develops cognition and thus is able to develop higher cognitive dimensions further. The links between these areas are of utmost importance for education and, above all, for developing of students' scholarship. Each student can be educated, and it is necessary to influence them to develop their personality and all of their potential abilities. The conceptual four-sector model represents the initial pathway to lead students who are differentiated according to the intellectual level and academic achievement to the active development of thinking, learning and critical insight. Keywords: cognitive process dimensions, abstract visual thinking, intellectual level, motivation to learn, academic achievement.

An Analysis of Polysemy of “anding-andingen” Proverb in Karo Language: Problems of Natural Semantic MetaLanguage
Authors: Tarigan Karisma Erikson , Mulyadi Mulyadi
Published: December 2020

This article aims at proposing a way to identify polysemy ‘anding-andingen’ or proverb in bahasa karo. The writer has an interest to use proverb or anding-aningen in this study because in proverb contains a lot of semantic meaning. This study was conducted using the descriptive qualitative approach in nature; therefore it only describes the semantic knowledge theory. The results of this study indicate that the element DO may occur either with a subject (Actor) alone with a second (Patient) argument as well (in English, as DO TO). It opened the way for a new semantically-inspired approach to grammar constructions. An analysis of ‘X does this’ as ‘X can say this’ and of ‘A because B’ as if not B, the not A’, the writers admitted that both DO and BECAUSE into the stable of semantic primitives. A similar entailment-like relationship obtains between PEOPLE and SOMEONE, but there is at least one significant syntactic difference, namely, that PEOPLE cannot occur with quantifier ONE.
