Published: February 2022

Objetivou-se identificar a QV de pacientes com câncer gastrointestinal e dor crônica e caracterizar os dados sociodemográficos, clínicos, terapêuticos e de gradação da dor, associando-os aos domínios de QV. Trata-se de um estudo transversal, quantitativo, do qual participaram pacientes com câncer gastrointestinal e dor crônica, atendidos em ambulatório de gastroenterologia oncológica de um hospital geral, na cidade de São Paulo, Brasil. Utilizou-se um questionário sociodemográfico e clínico, o instrumento EORTC -QLQC30 e o Brief Pain Inventory (BPI). Os dados foram submetidos a análise descritiva, frequências absolutas e porcentuais, e analítica, buscando-se correlacionar os domínios de QV, Dor, Performance Status (PS) dos pacientes, mediante o coeficiente de correlação de Spearman. Para comparar os domínios das escalas do QLQ-C30 e BPI com as variáveis de interesse, utilizou-se Teste T. Participaram do estudo 13 pacientes, maioria sexo masculino, casado, religioso, classificação econômica C2 (61,5%). Todos encontravam-se com dor no momento da coleta de dados, com média 2,54 (DP=2,88) pelo BPI e com pior escore referido das últimas 24 horas em 8,15 (DP=2,03). As principais alterações de QV evidenciadas foram, além da dor: fadiga, insônia e perda de apetite, sendo que quanto mais avançada a doença, piores os sintomas e o prejuízo funcional. Os dados evidenciaram que os pacientes convivem com dor de intensidade moderada e, se pior estado clínico, maior intensidade. A dor compromete a qualidade de vida desses pacientes em múltiplos aspectos, evidenciando que medidas precisam ser empreendidas para favorecer o controle álgico, do esquema terapêutico medicamentoso às atividades educativas e assistenciais.

Sanitary landfill leachate (SLL) is a mixture of highly toxic and recalcitrant pollutants that threatens the water quality of the Yucatán Peninsula karst aquifer, one of the most extensive aquifers on the planet. To reduce the adverse environmental impacts of this wastewater, a triple-stage Fenton process (FP) was applied in an old SLL. Removal efficiencies were evaluated in terms of physicochemical variables, metal(oid)s concentrations, mass spectrometric identification of organic compounds and Daphnia magna acute toxicity test. The triple-stage FP achieved an 88% chemical oxygen demand (COD) removal, representing an improvement of 13% compared to FP performed in a single stage. Further, metal(oid)s such as aluminum, arsenic, chromium, nickel and zinc as well as organic compounds were substantially reduced. With respect to acute toxicity, the treatment produced a 64% reduction. Thus, this treatment system seems to be an effective option to reduce the dangerous level of SLL.

Published: February 2022

Considering the current environmental problems that has been generated by the excessive production of synthetic plastics, more sustainable alternatives have been proposed. One of these recently studied materials are the mycelium composites, a product obtained with lignocellulosic particles agglomerated together by the myceliar growth of a filamentous fungus. This novel type of materials could represent an option to replace non-biodegradable materials. In this work, mycelium composites with characteristics comparable to expanded polystyrene (EPS) and potentially suitable for fabrication of insulation panels were developed using a Lentinus crinitus strain previously selected after mycelial phases tests. Mechanical variables in bending, compression strength and stiffness were measured following ASTM D143 standard. Two protocols for composite fabrication were followed using different compression loads. Flexural strength reached 0.48 MPa and compression strength 0.235 MPa. Results obtained were compared with data of balsa wood (Ochroma pyramidale) for the similarity of possible applications, expanded polystyrene as its possible substitute and early published data on mycelium composites. Mechanical performance in flexural and compressive strength of the obtained materials revealed their potential use as biodegradable alternatives to some applications of synthetic plastics as insulation panels and packing materials.

Published: February 2022

Recent studies show limited research on the development of learning media that effectively addresses critical thinking, communication, collaboration, and creativity(4C) characteristics. However, there is an urge for nurturing the 4C characters of vocational high school graduates in the 21st Century, especially critical thinking. Hence, this study aims to develop and discover the feasibility, usability, and effectiveness of critical thinking-based interactive learning media for Basic Mechanical Engineering. This study used the Analysis, Design, Development, Implementation, and Evaluation (ADDIE) development concept. The information design in developing the learning media was based on critical thinking aspects by Facione in ATC21S. The critical-thinking-based interactive learning media (CTBILM) were developed for mobile learning which can be used in IOS and Android. The alpha test showed promising results, especially from material experts. In addition to that, the User Acceptance Test (UAT) also shown a significant score making CTBILM quite feasible. We also argue that the significant change in student critical thinking from the statistical t-test on pretest and posttest are due to CTBILM.

Published: February 2022

This study, which was guided by three research questions, used the qualitative method of a case study to explore the level of implementation of the academic probation policy in North-Western Nigeria, and how it impacted on academic performance of students. The population for this study included examination officers. The population is not intended to statistically represent a group on campus but is instead a group of individuals who shared a specific educational experience. Data was collected through interviews with Examination officers in the selected colleges and analyzed using the thematic data analysis technique. Findings of the study revealed that the colleges are implementing probation on students whose CGPA is less than 1:00 point in line with NCCE probation policy. It further revealed that the implementation of probation has positively impacted the probating students by making them work harder to remedy their deficiencies, improve their performances and subsequently pass their examinations to meet their graduation requirements. The study also found out that most of the probating students see probation as a punishment, a very difficult process, and an unpleasant situation. The study, therefore, recommended that Guidance and Counselling Units of colleges of education should always guide probating students on the importance of the policy for the improvement of their academic performances, and colleges of education should always make sure that experienced and qualified lecturers handle students on probation.
Confusion of the Use of Been and Being by English as Second Language Learners in Nigeria
Authors: Tafida Amina Gogo , Dhalhatu Bala Muhammad , Usman Mohammed Alhaji
Published: February 2022

English language teaching in Nigeria is faced with numerous challenges resulting in negative academic performance of students at various levels of education. Some of the challenges include unqualified and inexperienced English language teachers, inadequate space allocation for English language on the school timetable, improper teaching methods, lack of English language specialists to teach the various aspects of English, giving emphasis to some aspects of the language than the other among others. The paper takes a look at the confusion of the use of been and being by English as second language learners which might be due to less emphasis given to that aspect of the language during the teaching/ learning process. A test containing 30 questions was administered on two groups of schools- public and private. In each of the schools, some SS3 and JSS3 students were sampled for the study and the results show significant error margins of more 50% in the two sets of respondents. Tables and pie charts were used to show the findings. The major findings of the study show that: the verb forms, ‘been and being’ are confusing to English as second language learners especially at secondary school level; there is significant difference in the level of confusion in the use of been and being by students in public and private secondary schools in Minna metropolis and there is significant difference in the level of confusion in the use of been and being by senior secondary school students in public and private schools among others. Some of the recommendations offered are: the teaching of language forms should be accompanied by numerous real life examples; Language teaching should progress from known to unknown; it is essential to use substitution tables to provide the learner with enough practice on language use; and that qualified English language teachers should be employed to teach English language. These findings and recommendations are expected to improve the teaching and learning of English as second language.
The Scourge of Uterine Fibroid among Females: Psycho-sociological Explanations from Lagos and Ondo States in South-west Nigeria
Authors: ARUNA Justina Olufunke , ADEOBA Gbemisola Hannah
Published: February 2022

Uterine fibroid and ovarian cyst has become the prevailing scourges modern Nigerian women must contend with. Fibroid tumor is usually benign, comprising of muscle tissues that are non-cancerous. It can have different symptoms, depending on whether it is located in, on, or within the walls of the womb. Often times, this problem is threatened by inappropriate and even ignorant medical attention and/or medical diagnoses that miss the real health problems. In this sociological study of the body, the paper seeks to examine the causes of uterine fibroid among females in relation to high-stress, diet, quality of life, emotional, and environmental inter play within the cultural context of the study. The study by extension, relates the growth of fibroid to the pervasive poverty level in Nigeria. This study employs participant observation and in-depth interview methods involving 60 women between, the ages of 20-56years that were purposively selected. Based on the adage in medicine that “good girls have fibrous, bad girls have babies”, this paper submits that the poor elimination of congestion and nervous system imbalances, nutritional, emotional imbalances as a result of the impinging factors inherent in the socio-cultural environment and psycho-sociological related problems and poverty are responsible for the prevalence of cases of fibroid among Nigerian women. The paper then recommends a holistic approach, ranging from wholesome nutrition, family/spousal support, calisthenics, emotional “coolness” in most situations, and provision of proper medical facilities by the Government, as a necessary criterion to removing the “diseased body” (of women) from the politics of exclusion.
Ideologias e políticas linguísticas – uma análise da obra Amik loves school: a story of wisdom
Authors: Mello Layssa Gabriela Almeida e Silva , Figueredo Carla Janaina
Published: February 2022

Neste artigo, utilizaremos a obra Amik loves school: a story of wisdom (VERMETTE, 2015a) como motivadora para refletir sobre questões referentes a ideologias de linguagem (WOOLARD, 1998;KROSKRITY, 2004; BAKHTIN, 2009), colonização (HELLER; MCELHINNY, 2017), apagamento (IRVINE; GAL, 2000) e, assim, problematizar algumas políticas linguísticas canadenses, tal como o Indian Act (1876). Segundo o referido documento, a educação escolar indígena deveria seguir os moldes linguísticos e culturais das identidades brancas europeias, o que fortaleceu ideologias imperialistas que deslegitimavam as línguas e culturas das primeiras nações canadenses em contextos como as residential schools. Katherena Vermette revela, no entanto, que sua obra literária é construída de modo a promover ações de ruptura com tais processos de assimilação, as quais pretendem envolver o seu público não somente com personagens indígenas e suas histórias, mas, sobretudo, com reflexões capazes de desconstruir ideologias imperialistas ao mesmo tempo em que valoriza as identidades linguísticas e culturais dos povos indígenas. O texto de Vermette nos lembra a trajetória de povos indígenas brasileiros em tempos de colonização e de atual condição subalterna. Sendo assim, as semelhanças históricas e socioculturais compartilhadas por etnias canadenses e brasileiras nos levam a crer que a leitura e a discussão da obra de Vermette em contextos de ensino-aprendizagem de inglês no Brasil podem promover espaços para o diálogo entre diferentes línguas e culturas e a sua valorização pelos aprendizes.
Propaganda “Agro, a indústria-riqueza”: uma análise da (re)produção de sentidos sobre a agricultura familiar
Authors: Stefanello Alessandra , Souza de Medeiros Caciane
Published: February 2022

O Brasil, um país que tem sua história marcada por embates na/pela terra, agora recebe holofotes midiáticos pelo sucesso do agronegócio. Na tentativa de visibilizar esse sucesso, grandes emissoras produzem materialidades que põem em circulação o “tudo” que é o agronegócio, sendo uma dessas a Rede Globo de Televisão. Por isso, tomando como nosso corpus a propaganda “Agro, a indústria-riqueza do Brasil. Agricultura familiar é Agro”, buscamos analisar como se dá a (re)produção de sentidos acerca da agricultura familiar no discurso da/na mídia e compreender como é projetada, pela propaganda, a relação de sentidos entre agronegócio e agricultura familiar. Para tanto, filiamo-nos à Análise de Discurso materialista (doravante AD), fundada por Michel Pêcheux, que toma o discurso pela sua opacidade e sua heterogeneidade, a partir de determinadas condições de produção. A partir dessa perspectiva teórico-metodológica, veremos como o discurso da/na mídia tem um efeito de completude e de totalidade, buscando apagar determinados sentidos em detrimento de outros e, consequentemente, deslocando o que seria agricultura familiar a favor de um efeito de unidade no cenário agrário brasileiro. Assim, nosso estudo centra-se nos embates agrários, que atravessam não só nosso território, mas, sobretudo, nossa língua.
As práticas contemporâneas de linguagem e o professor de língua portuguesa: uma leitura narratológica da BNCC
Authors: Merith-Claras Sonia
Published: February 2022

A publicação da Base Nacional Comum Curricular (BNCC) vai colocar em evidência o quanto as tecnologias digitais de informação e comunicação colaboraram para o desenvolvimento de novas práticas de linguagem. As transformações acerca do uso da linguagem, nesse contexto tão midiático, melhor se refletem na organização do componente curricular Língua Portuguesa, objeto de estudo neste trabalho. Para melhor compreender a organização do Componente, bem como traçar o perfil, ou ainda, a imagem do professor de língua portuguesa pressuposto na Base, realizamos um estudo que envolve a narratividade da enunciação. Isto é, respaldados pela Semiótica Discursiva, de linha francesa, ao longo deste texto detalhamos como o processo persuasivo se estabelece entre enunciador-destinador e enunciatário-destinatário, evidenciando quais os valores em jogo, bem como os percursos figurativos e temáticos que recobrem a proposta. São as escolhas do enunciador-destinador, articuladas ao longo do Componente, que vão constituir a imagem de um professor (o páthos do enunciatário) mais reconhecido pelo seu saber no trato com as linguagens que pelo domínio e conhecimento da linguagem verbal.
A metaforização dos sentidos na nomeação do ensino escolar em tempo de pandemia
Authors: RIBEIRO ANA CLAUDIA DIAS , Oliveira Ana Cláudia Martins De
Published: February 2022

Neste trabalho, objetivamos problematizar a metaforização dos sentidos das palavras utilizadas para nomeação do ensino escolar, em tempos de pandemia, por meio dos enunciados contidos na materialidade discursiva em notícias de jornais e documentos oficiais que circularam, na mídia, durante o período de suspensão das aulas presenciais. Nossa pesquisa fundamenta-se no campo teórico-analítico da Análise de Discurso (doravante, AD) de matriz francesa, partindo das teorizações de Michel Pêcheux e de outros autores passíveis de diálogo com essas teorias. Buscamos compreender a utilização de diferentes formulações referentes ao ensino escolar, tais como remoto, a EaD e as aulas on-line, analisando como elas se inserem na memória discursiva, modificando e deslocando-se nas materialidades que circulam em meio ao acontecimento discursivo, pandemia. Em nosso gesto de interpretação, vamos descrever e interpretar a materialidade selecionada, observando a metaforização como constitutiva do funcionamento da discursividade, considerando que a metáfora é o ponto de articulação entre o equívoco e o non-sens. As análises mostram que a pandemia propiciou um deslizamento na forma como o ensino escolar é significado. O espaço escolar não é mais o mesmo, as metodologias de ensino também não são, pois a sala de aula migrou para a casa dos professores e dos alunos.
Medición científica y el caso de Einstein contra Lorentz
Authors: Aguilar Sandoval Miguel Agustín
Published: February 2022

A inicios del siglo XX, Albert Einstein y Hendrik Lorentz produjeron explicaciones diferentes acerca de los mismos fenómenos. Sin embargo, rápidamente se produjo un consenso, en favor de Einstein, que ha sido difícil de comprender para historiadores y filósofos de la ciencia. La literatura reciente explica ese éxito señalando conflictos entre algunas ideas de Lorentz y la temprana física cuántica. Sin negar que esos factores pudieron contribuir en la aceptación de la relatividad especial, propongo una explicación complementaria en la que atribuyo el éxito de Einstein al uso de la estabilidad de la medición de la velocidad de la luz.

Published: February 2022

Heavy workloads and uncertain working hours on TNI soldiers can trigger burnout. With the existence of burnout, social support from people around is expected to be able to contribute to preventing or reducing the level of burnout on TNI soldiers. The purpose of this study is to find out a contribution from social support in the work environment to burnout in the army. Respondents in the study were 202 people aged 21-30 years with a work period of more than one year. The data collection technique used in this study was purposive sampling. In this study, social support that acts as a variable (X) was measured by instruments from Adrian in 2014 which obtained a reliability value of 0.925. Whereas, to measure burnout which acts as a variable (Y) the MBI (Maslach Burnout Scale) instrument was used which was tested by Andarini in 2018 with a reliability value of 0.902. In this study, the data obtained were analyzed using simple linear regression with the results that showed that there was a negative effect of social support on burnout on Army soldiers (B = -0.482). It can be explained that the higher the social support received, the burnout experienced will be low. Conversely, if the social support received is low, the level of burnout experienced will be even higher. Based on research results, social support has a contribution of 24% to burnout.

Published: February 2022

Colorants, which have an important place in food additives, are defined by the International Food Codex Commission as "a substance that regulates the color of food or is added to give color". The Joint FAO/WHO Expert Committee on Food Additives (JECFA) affiliated with the Codex Alimentarius Commission (CAC) formed by the World Health Organization (WHO) and the Food Agriculture Organization (FAO) as part of the United Nations (UN) organization, is an authority that makes suggestions and recommendations on all matters concerning the additives. Different opinions have emerged in studies evaluating food additives in terms of health risks involved. In various studies investigating colorants in foods, it has been reported that the permitted colorants are used in high amounts and also that non-permitted colorants are encountered. In various epidemiological studies, it is stated that colorants cause diseases such as asthma, hypersensitivity, skin rashes, premature childbirth, migraine, cancer, thyroid, tumor, and chromosome damage in humans.
Technological Methods of Increasing the Resource and Efficiency of Fast-Wearing Working Bodies
Authors:   Federal Scientific Agroengineering Center VIM, Mironov Denis A.
Published: February 2022

The working bodies of tillage machines are operated in a soil abrasive environment and, due to wear, they change their shapes and sizes, which negatively affects tillage agrotechnical and energy indicators. The problem of increasing the durability and operability of the working bodies of tillage machines remains relevant. In particular, this is reflected in the reduced resource of serial tillage working bodies. (Research purpose) The research purpose is to ensure the increased durability and efficiency of agricultural machines. (Materials and methods) The downtime of agricultural machinery due to the failure of tillage working bodies negatively affect the efficiency of agricultural operations and entail up to 15-20 percent reduction in subsequent yields. The cost of purchasing and reinstalling spare parts is up to 18 percent in the structure of the cost of agricultural products. The most technological method of plasma-powder surfacing (hardening) has been used, which is up to two times more productive and 2.2-2.7 times more economical in comparison with the known technology of plasma surfacing in argon medium. The most high-strength (σВ at least 1600 megapascals) steels of the type 25XGTYUR, 30XGSA, 27XGR were selected for the manufacture of the developed tillage working bodies. (Results and discussion) Parts made of high-quality materials according to the created technology are not inferior in resource and wear resistance to the best foreign surfaced analogues, and non-melted imported products are 1.5-1.7 times superior. New materials and technological surfacing methods for strengthening domestic and import-substituting working bodies of agricultural machines allow, in terms of resource and operational indicators, to achieve a level of competitiveness with leading foreign manufacturers. (Conclusions) According to the «quality-price» criterion, new working bodies with reasonable materials, structural and technological parameters have a 1.5-2.5 times advantage over the best foreign analogues.

Published: February 2022

Currently, one of the main tasks facing agricultural production is to provide the country’s population with high-quality food with a maximum reduction in the share of imports. To get stable and high yields, it is necessary to use modern equipment. Recently, the main emphasis has been on equipping machines with electronics, while less and less attention is paid to the design of agricultural machines. Despite the large number of mechanization means of soil rolling, they often do not ensure the fulfillment of agrotechnical requirements for soil rolling. (Research purpose) The research purpose is to test the effectiveness of using the developed vibrating roller in the field on soybean crops. (Materials and methods) The article presents the fundamentally new vibration roller, the distinctive feature of which is the presence of a passive drive of disbalancers mounted on the rotating axis of a hollow cylinder. In the field conditions, the quality of work of the developed vibrating roller and mass-produced rollers was compared using the coefficient of compliance with the standard. (Results and discussion) The use of a vibrating roller give a higher quality of soil rolling, a 42 percent better value of the optimization criterion compared to the KKZ-6 roller. The soybean seedlings are more harmonious compared to rolling in other rollers. (Conclusions) The rolling of soybean crops with the proposed vibrating roller allowed to increase its yield to 33.5 quintals per hectare (by 27.4 percent) compared to 26.3 quintals per hectare after rolling the crops with the KKZ-6 rollers mass- produced by the industry.

The soil is a favorable environment for many microorganisms, pathogenic bacteria, fungal spores, insect eggs due to the presence of nutrients and moisture in it. Soil treatment from pests and pathogens of agricultural crops for the purpose of disinfection can be carried out by chemical, energy, thermal and biological methods. The most common method is thermal. The article proposes to use infrared heating as an alternative energy source. (Research purpose) The research purpose is developing energy-resource- saving installations for disinfection of soil and substrate. (Materials and methods) The article presents three devices and their capabilities for disinfection of soil and substrate with infrared radiation. (Results and discussion) One of the options for progressive scientific and technical developments is the development of software management of soil and substrate disinfection for the implementation of energy-saving electrical technologies, which regulates parameters depending on the set values: heating time, height of the frame with IR burners above the ground, humidity, porosity, soil temperature, ambient temperature and power of infrared burners. (Conclusions) During the analysis of the state and prospects for the tillage before planting, the need for the development of scientifically based devices for disinfection of soil and substrate was justified. The proposed use of software control of soil and substrate disinfection will allow setting and maintaining the required level of treatment depending on the technological process, type of soil, open or closed ground. The use of an automatic disinfection control system will make it possible to achieve optimal processing parameters and increase productive indicators.

Ensuring a stable feed base is one of the most important conditions for intensive livestock farming. Another necessary and obligatory condition is the use of modern methods of feed preparation with the use of highly efficient technical means. Evaluation of the effectiveness of the developed technical means should be carried out not by one indicator, but by a set of specific indicators combined into a complex criterion, taking into account the importance of all selected private indicators. (Research purpose) The research purpose is selecting the most important specific indicators for a comprehensive assessment of the effectiveness of the root crops cutter based on the analysis of scientific papers and the functioning of technical means used for the cutting of root crops for cattle feed. (Materials and methods) The methodological basis for the selection of indicators for a comprehensive effectiveness of the cutter was the effectiveness theory of the technical means. The initial material for determining the specific indicators of an efficiency assessment was their technical characteristics and quality indicators of the technological operation. (Results and discussion) Based on the analysis of research work and production experience, two key groups of indicators were identified for the effectiveness assessment of the cutter. They are the power for cutting – Nизм, labor costs per unit of cutted products – Зт, capacity of the cutter – Wч, operating time for failure – t0, time spent on the elimination of technological malfunctions – tтехнол, specific labor cost of maintenance tуд.ТО, level of juice loss Пс. It was proposed to determine the relative importance of each specific indicator by the method of expert evaluation. (Conclusions) Indicators for a comprehensive assessment of the efficiency of the use of root crop shredders are economic and quality. The economic indicators were attributed to the power costs for cutting root crops and labor costs during cutting; quality indicators include the productivity of the cutter per unit of time, operating time for failure, time spent on eliminating technological malfunctions, specific labor cost of the cutter maintenance and the level of juice losses.

The analysis of transport and transport-technological means is carried out both by types of work performed, and in the context of transport types – tractor and automobile. As a result of mathematical data processing, the structure of the nomenclature of agricultural goods was described, the share components of transport and transport-technological processes, peak periods of transport support of production processes were determined. (Research purpose) The research purpose is to study the nomenclature of agricultural goods and materials necessary to ensure the implementation of the activities of modern agricultural producers, to analyze transport and transport-technological processes associated with the production of crop production on the example of a typical farm of JSC «Zelenogradskoye», taking into account the production and agro-landscape conditions of the Moscow region. (Materials and methods) The article presents the detailed analysis of the transport support of agricultural production processes in the implementation of transport tasks in the conditions of the Moscow region. The article describes the justification that the studied farm matches with the average indicators of production and agro-landscape conditions of the Moscow region. (Results and discussion) The nomenclature of goods was determined based on the study of the transport support of technological processes of JSC Zelenogradskoye, consisting of 165 types used in the production activities of the enterprise, as well as construction works. Tractor transport unit (58.6 percent) and motor transport (41.4 percent) were used for cargo transport and technological processes as mobile energy means. The analysis of the change in the volume of cargo transportation by month by various modes of transport showed that there is a correlation of graphs. The share of tractor transport operation is higher in winter, which is explained by the poor condition of roads connecting rural areas. (Conclusions) The study of transport processes makes it possible to understand and determine the complex structure of the interaction of various, constantly changing production factors, and optimize the line of vehicles with reasonable parameters for the effective performance of transport and technological processes in agricultural production.
