The production of red ceramics (tiles and bricks) was an important activity for the economic development of the municipality of Morro da Fumaça, state of Santa Catarina, Brazil from the 1960s onwards. This segment was a major contributor to the introduction of labor female labor in the local economy. The activity still has great economic relevance for the municipality, since it is a source of tax collection and generation of direct and indirect jobs, for a representative portion of the population. This study aims to narrate the way in which the production and development of red ceramic production took place in the municipality of Morro da Fumaça, south of Santa Catarina, Brazil, confronting it with the social reality of the actors that make up the productive force sector, especially female workers. From the female performance, analyze the working conditions to which they were submitted. Such conditions, at times, imposed a double working day in the activity of ceramic production, work in a family nucleus with the inclusion of minor workers, in addition to the responsibilities with domestic chores.

Published: March 2021

This research aims to analyze whether Intellectual Property assets of Federal Institutes (FIs) in Northeast Brazil are being measured, accounted for and evidenced in Financial Statements (FSs) of these Scientific, Technological and Innovation Institutions (STIIs).Therefore, in order to achieve the proposed objective, a bibliographic, exploratory, and descriptive research was carried out. This survey was achieved through a qualitative approach from document analysis and collection of secondary data related to innovation policies of FIs, and valuation and accounting of IP assets. The results showed that patent registrations granted and Technology Transfer (TT) are still incipient, although the majority of the Technological Innovation Nuclei (NITs) of Northeast FIs have innovation policies that support intellectual protection of inventions. Even though there are Brazilian Accounting Standards (NBCs) that uphold the process of measuring, recording and disclosing of IP assets, such as NBC TG 04 (R4, 2017a) and NBC TSP 08 (CFC, 2017b), this result can also be due to an absence of structured and guiding procedures within the scope of NITs’ innovation policies.

“Homosexualism”, “sexual orientation disorder”, “egodistonic homosexuality”, “unspecified sexual disorder”, “sexual maturity disorder” and “sexual relationship disorder”. Since 1948, these have been, throughout the history of the Diagnostic and Statistical Manual of Mental Disorders (DCM) and the International Statistical Classification of Diseases and Related Health Problems (ICD), the terms used by the scientific community to categorize the homoaffective spectrum until in 2017, in the face of strong social and academic demand, their complete disengagement from any terminology that categorizes them as physical and/or mental illness. On the other hand, some areas of science have contributed substantially to a better understanding of this subject, such as genetics and epigenetics. Today, although the scientific community still offers some points of resistance, especially in more conservative countries, it is a consensus that since the implementation of the genome project there has been a considerable methodological expansion that has opened new possibilities of studies that have allowed this advance.

Published: March 2021

The role of assessment in the teaching and learning of Mathematics cannot be underestimated. Therefore, efficacious teaching and learning of Mathematics must be driven by effective use of assessment. This study, therefore, sought to investigate the Use of assessment (practices) of Beginning and Experienced SHS Mathematics teachers in two selected districts in the central region of Ghana. In this study, Assessment Practices means what SHS teachers use assessment to do in the teaching and learning of Mathematics under the auspices of a school. A sample of 160 SHS Mathematics teachers was used in this study. These were made up of 92 Beginning and 68 Experienced SHS Mathematics teachers. The instrument used in this study was a questionnaire. The questionnaire was administered to the 92 Beginning and 68 Experienced SHS Mathematics teachers in the two districts in the Central Region of Ghana. The design used in this study was a cross-sectional survey. Data collected from the respondents were analyzed using frequencies, percentages, means, and standard deviations. An independent sample t-test was used to test whether there exists a significant difference in the assessment practices of the Beginning and Experienced SHS Mathematics teachers. It was found out that the majority (87 out of 92) of the Beginning Senior High School Mathematics teachers do not either frequently or always integrate assessment in the teaching and learning of Mathematics. It was also found out that the majority (60 out of 68) of the Experienced Senior High School Mathematics teachers also do not either frequently or always integrate assessment in the teaching and learning of Mathematics. They rather see classroom assessment as an additional activity that mainly comes at the end of the teaching-learning process. The study also revealed a significant difference in the assessment practices of Beginning SHS Mathematics teachers and that the Experienced SHS Mathematics teachers in the two districts. Based on the findings, it was recommended among other things that In-service training should be organized for both the Experienced SHS Mathematics teachers and the Beginning SHS Mathematics teachers to help them bridge the gap that exists between their practices.

Authors: A V Sekhar , Prabu M.
Published: March 2021

The paper is aimed at elucidating the measures that the marketers take to Develop & Promote products and do product differentiation through product innovations to manage favourably the product life cycles - fighting competition both for sustenance in the market and/or to enlarge market shares. They choose to create better and consistent customer awareness with emotional appeal on the one hand and add value to the products bringing in new or altered product features when needed to deliver enhanced benefits that the buyers in the market look for. That is, in order to give the products / brands prolonged life cycle, the marketers develop their products, do promotions and also product innovations (to add value to products for better performance, look & feel of them), in a bid to differentiate them from those other similar competing products/brands. Product life cycles are the captured performance graphs for the products, which could be considered as prescriptions for corrections of products and brands in their tangible and intangible features so as to make them spring back to perform to the levels. The paper thus focuses on the practices that the marketers undertake to do in order to win the hearts of the buyers. The larger objective of the paper is to throw light on all the initiatives of the marketers which they would do to match the customer preferences

Purpose: The psychological capital and the self-determination theory are areas related to the research of human behavior in organizationsThis study had as objective to verify if there are relations between the categories of Motivation with the dimensions of Psychological Capital.

Design/methodology/ approach: it was performed a quantitative empirical study. The sample consisted of 235 workers working in the health sector, in south of Brazil. Data collection was obtained through the application of PCQ-24 and MWMS.

Findings: There is a negative correlation between psychological capital and demotivation as well as a positive correlation between psychological capital and intrinsic motivation. It was observed that the higher level of psycap more the results approached the intrinsic motivation. The results suggest that care professionals have higher levels of motivation for work and psycap than those in administrative area. Likewise, people with a complete undergraduate level had high levels of Motivation and Psychological Capital. In sum, the results suggest that Psycap is an important contribution to motivation at work.

Research limitations/implications: This empirical research was performed only with a sample of health workers from Brazil. For this reason the results can not be generalized.

Practical Implications: It is possible to verify the level of Motivation and Psychological Capital of the workers, being able to develop strategies to develop skills that promote better organizational performance.

Originality/value: It has conducted a research with two instruments still little used in the Brazilian context - PCQ-24 and MWMS - relating these two approaches in a health sample.

Published: March 2021

The biggest impediment to the viability of Solidarity Economy Enterprises (SEE) is the credit issue, which due to lack of guarantees means that they cannot access credit through traditional banking channels and end up failing. In view of this unfavorable scenario, the objective of this work is to make a propositive contribution, evidencing elements that are useful to enterprises of solidarity economy in relation to obtaining credit. To do so, it relied on bibliographic research to link these factors, highlighting those that can be controlled by the SEE, as well as those external so that the credit assignment occurs, which resulted in the elaboration of a propositive instrument, with elements that facilitate the assignment of credits both in the user's view and in the institutional view. Its usefulness could be verified with a field research, conducted with 25 solidarity economy enterprises, which answered a questionnaire informing whether the existence of such an instrument would help in reducing the difficulties of obtaining credit, as well as being able to contribute with eventual adjustments.

Authors: Appel Lora , Peisachovich Eva , Sinclair Donald
Published: March 2021

Since the release of more affordable, portable, and easy-to-use virtual reality (VR) systems in 2014, there has been renewed interest in using this technology in education, as an alternative to traditional learning, because it creates more opportunities for experiential education. Despite the many benefits and affordances of VR, widespread adoption in post-secondary education has been limited, and gaps remain in the provisioning of detailed guidelines for implementing this technology in curricula. Our team developed the CVRRICULUM (CVR) initiative: a pilot program that recruited instructors to adapt a traditional written assignment into a VR format. A mixed-methods approach was used to collect data from five instructor and 18 student participants. In this manuscript we describe the implementation process, report the identified challenges, and provide suggestions that should improve subsequent offerings. Our team addressed raised challenges by creating a set of resources available on the CVR website.

Published: March 2021

There has been an increase in the flow of freight vehicles commuting on Brazilian highways. Then, special attention to the structural performance of bridges regarding the fatigue in beams is needed. Brazil has neither normative metrology to study real data flow of vehicles, nor specific fatigue load train models and coefficients to the analysis and design of road bridges. The same load train that is used for general dimensioning, TB 450, is used for the fatigue verification. Hence, this work aims to verify if the current TB 450 is representative of the freight heavy vehicles with 2 to 9 axles concerning the effects of fatigue in the longitudinal reinforcement of beams of theoretical reinforced concrete bridges with two, three, and five beams. This verification is performed analyzing the stress variations found in the longitudinal reinforcement of vehicles with 2 to 9 axles and the TB 450. Based on the results, the longitudinal steel reinforcement was more susceptible to fatigue's effects. Freight vehicles with 5, 6, 8 and 9 axles presented the most significant stress, therefore, they tend to cause more deleterious effects. Hence, the adoption of a Brazilian normative fatigue specific load train and coefficients is necessary to analyze pre-existing road bridges and design new ones most accurately.

Published: March 2021

With the vulnerability, unpredictability, and ambiguity of the situation, schools all over the world have faced a variety of restrictions and unprecedented risks that caused some to cease operations and classes permanently or for an extended period of time. The concept of risk has become closely associated with every school process and structure so as to aid them in adapting to the current situation. This paper explores the concept of risk management and risks planning through the lens of school management and the Plan-Do-Check-Act (PDCA) Cycle. Furthermore, the researchers link the permeation of the direct and indirect effects of risks in the school system by reflecting on the layers of the school’s bioecological nest as adapted from the Bioecological Theory of Urie Bronfenbrenner. Finally, this paper suggests a model for risk planning that can help school administrators and leaders in managing risks and aid future researchers in studying concepts related to risk management.

Performance assessment and sustainability of Civil Society Organizations
Authors: De França Jose Antonio
Published: March 2021

This article presents the results of a quanti-qualitative research process that introduces a theoretical model of sustainability assessment of non-profit Civil Society Organizations (CSO) within the tertiary sector. The theoretical model, in the quantitative approach, is composed of performance assessment indicators, efficiency and efficacy metrics, and a cash flow generation matrix (CGM) by applying basic matrix algebra. In the qualitative approach, the model encompasses indicators of satisfaction and social integration. In both approaches, the evaluation is separated by project, both individual and joint, taking into consideration each project’s independence and autonomy. The evaluation process is executed within the context of a governance commitment that uses voluntary service and offers non-state public services. The answers of the model, tested with academic data, anchor robust and meaningful contributions to the literature of sustainability assessment of tertiary sector organizations. Lastly, considering that the results obtained with standardized financial and accounting statements may hinder the model’s potential, it is encouraged that empirical research is conducted with managerial data.

Published: March 2021

The trend of scientific development in the future cannot fail to mention the great influence of the space field, but in the immediate future, the observational satellite systems are related to communication technology. In fact, in some countries with strong development of communication technology and space technology, the mechanical system of geostationary satellite monitoring antennas has certainly been thoroughly resolved. However, because of a specific technology, the sharing and transferring of design and manufacturing technology to developing countries is a great challenge. It is almost difficult to find published works related to mechanical design calculation and manufacture of geostationary satellite monitoring antenna systems. The problem of proactive grasping of technology, step by step autonomy in manufacturing technology of telecommunications equipment related to space technology has always been the goal of developing countries like Vietnam to limit technology dependence, minimizing technology transfer costs, ensuring national security. The first step in these problems is the autonomous construction of terrestrial transceivers such as geostationary satellite monitoring antennas. This paper presents the kinematics modeling analysis of the mechanical system of the geostationary satellite monitoring antenna. Each component of the antenna system is assumed a rigid body. The mathematical model is built based on multi-bodies kinematics and dynamics theory. The DENAVIT-HARTENBERG (D-H) homogeneous matrix method was used to construct the kinematics equations. The forward kinematics problem is analyzed to determine the position, velocity, acceleration, and workspace of the antenna system with given system motion limits. The inverse kinematics problem is mentioned to determine the kinematics behaviors of the antenna system with a given motion path in the workspace. The numerical simulation results kinematics were successfully applied in practice, especially for dynamics and control system analysis of geostationary satellite antenna systems.

Published: March 2021

The experimental method used in a frontal crash of cars costs much time and expense. Therefore, numerical simulation in crashworthiness is widely applied in the world. The completed car models contain a lot of parts which provided complicated structure, especially the rear of car models do not contribute to behavior of frontal crash which usually evaluates injuries of pedestrian or motorcyclist. In order to save time and resources, a simplification of the car models for research simulations is essential with the goal of reducing approximately 50% of car model elements and nodes. This study aims to construct the finite element models of front structures of vehicle based on the original finite element models. Those new car models must be maintained important values such as mass and center of gravity position. By using condition boundaries, inertia moment is kept unchanged on new model. The original car models, which are provided by the National Crash Analysis Center (NCAC), validated by using results from experimental crash tests. The modified (simplistic) vehicle FE models are validated by comparing simulation results with experimental data and simulation results of the original vehicle finite element models. LS-Dyna software provides convenient tools and very strong to modify finite element model. There are six car models reconstructed in this research, including 1 Pick-up, 2 SUV and 3 Sedan. Because car models were not the main object to evaluate in a crash, energy and behavior of frontal part have the most important role. As a result, six simplified car models gave reasonable outcomes and reduced significantly the number of nodes and elements. Therefore, the simulation time is also reduced a lot. Simplified car models can be applied to the upcoming frontal simulations.

Published: March 2021

Among the methods of cultivation that increase the productivity of crops, a prominent role is assigned to crop rotation. In a properly constructed crop rotation, the efficiency of all agrotechnical methods aimed at improving the use of land increases, the biological needs of crops are satisfied, the rational use of technology is achieved, and the cost of production is reduced [1]. The soils are low in nitrogen, medium in phosphorus and high in potassium. The humus content is 1.2–2.0%, pH = 7–8. Studies have shown that green manure (sweet clover, oats, phacelia) have a positive effect on the balance of organic matter. The negative balance of organic matter is noted for pure steam. The stock of productive moisture in the 0–0.3 cm soil layer varied from 4.1 to 29.5 mm for winter wheat, 28.1–32.7 mm for chickpea and 28–35.3 mm for spring barley, depending on the weather conditions. conditions and methods of biologization. On average, over three years, the highest yield was in winter wheat for a busy fallow (phacelia) and amounted to 1.0 t/ha, which depended on weather conditions. A reliable correlation was revealed for the factors of yield-precipitation; temperature; batteries, etc.

Noinfectious diseases in industrial poultry farming: histological diagnostics
Authors: Gromov I. N.
Published: March 2021

Under conditions of egg and poultry farming noninfectious diseases are widespread and cause significant economic damage. These diseases can be caused by a variety of etiological factors: the deficiency of the necessary chemical elements, substances or their combination, excessive amount of certain classes of organic substances in feed. Diseases of complex etiology are also recorded, which arise from a combination of unfavorable factors and anatomical and physiological properties of individual bird crosses. Under the influence of unfavorable factors in various organ systems, pathological processes of various nature (dystrophic, necrotic, inflammatory) arise. In this case, the symptoms and pathological changes can be either similar or poorly visible macroscopically. In this regard, the results of histological examination of organs and tissues play an important role in making a presumptive diagnosis. The article introduces the original results of researches on pathomorphological diagnosis of the most widespread diseases in industrial poultry farming of noninfectious etiology: chronic feed borne toxicoses (including mycotoxicoses), hypovitaminosis A, hyposelenosis, amyloidosis, necrosis of the femoral head. The results of examination of spontaneous material stuff. The findings are formulated in the form of histological diagnoses. The attention is focused on the main (pathognomonical) signs of a great value for differential diagnostics of this group of diseases. Various variants of pathomorphological course of the diseases running both in a classical way, and in the form of a pathomorphosis (the variated pathoanatomical and histological lesions against application of vaccines and antibiotics) are considered.

Background: Acromegaly is an uncommon clinical disorder driven by high serum levels of growth hormone (GH) and insulin-like growth factor 1 (IGF-1). Over 99% of patients with acromegaly harbor a GH emitting pituitary adenoma. Pituitary tumors represent about 15% of essential intracranial neoplasms. Case presentation: A 38 years old woman, was referred to the H. Adam Malik central public hospital on December 15th, 2020, with chief complaints of enlarged fingers and toes. The patient complained that the patient's fingers and toes were getting bigger in the past 2 years. The brain MRI was performed showed intrasella spherical intensity lesions measuring ± 2.3x1.5x2 cm with the impression of macroadenoma. The patient later diagnosed with acromegaly due to pituitary macroadenoma. Therefore the patient was treated with administration of sandostatin injection, novorapid 6-6-6 IU SC, then 0-0-12 IU SC, 3x1 salt capsules. The patient is also consulted to the neurosurgery department for surgical management plans and a consulted to the Ophthalmology Department. Conclusion: We report an instance of acromegaly suspected because of pituitary macroadenoma in a patient with unmistakable clinical highlights, with comprehensive management.

Circulant $m$-Diagonal Matrices Associated with Chebyshev Polynomials
Authors: ÖTELEŞ Ahmet
Published: March 2021

In this study, we deal with an $m$ banded circulant matrix, generally called circulant $m$-diagonal matrix. This special family of circulant matrices arise in many applications such as prediction, time series analysis, spline approximation, difference solution of partial differential equations, and so on. We firstly obtain the statements of eigenvalues and eigenvectors of circulant $m$-diagonal matrix based on the Chebyshev polynomials of the first and second kind. Then we present an efficient formula for the integer powers of this matrix family depending on the polynomials mentioned above. Finally, some illustrative examples are given by using maple software, one of computer algebra systems (CAS).

Os embutidos em geral têm grande aceitação pela população por apresentarem baixo custo e praticidade no preparo. Porém, possuem baixo teor de fibras alimentares que previnem doenças crônicas não transmissíveis. A cevada é um grão altamente produzido no Brasil para produção de cervejas, resultando grande quantidade de resíduo de cervejaria, chamado de bagaço de malte de cevada, destinado à alimentação animal ou descartado no meio ambiente.  O objetivo desta pesquisa foi produzir uma salsicha com incorporação de farinha do bagaço de malte de cevada (FBMC). Foram produzidas cinco formulações de salsicha: 0%, sem incorporação de FBMC; e as demais de acordo com a porcentagem de incorporação, sendo elas 0,5%, 1%, 2% e 4%. O experimento foi conduzido no delineamento em blocos casualizados sendo os resultados submetidos à análise de variância, seguida de ajuste de modelos de regressão, ao nível de 5% de significância. Esta pesquisa permitiu a elaboração de um produto “tipo salsicha” com a incorporação da FBMC, com maior quantidade de fibra bruta, proteína bruta, firmeza e menor porcentagem de extrato etéreo em relação à salsicha controle. Verificou-se que a quantidade de cinzas diminuiu e a atividade de água não apresentou alteração significativa com a incorporação da FBMC. Quanto aos parâmetros microbiológicos, as salsichas se encontraram dentro dos requisitos pela legislação vigente. Estudos adicionais seriam interessantes para avaliar as características sensoriais do produto desenvolvido e seu potencial de produção em nível industrial.

Dietary fatty acids may influence the development of the digestive tract and initial activation of digestive enzymes in fish. The objective of this study was to evaluate the effect of the diet lipid profile on ontogeny and activity of digestive enzymes in silver catfish post larvae fed practical diets. Five diets were tested, replacing broiler liver by soybean protein concentrate (SPC) or fish meal (FM): Standard, 15SPC, 30SPC, 15FM and 30FM. The enzymatic activity of fish was analyzed from 32 Hours after fertilization (Haf). Were analysed acid protease, trypsin, chymotrypsin, lipase, amylase and maltase. The development of the digestive system was analyzed from first feeding up to 28 days by histological techniques. The enzymatic activity presented peaks for the post-larvae fed with the 15SPC diet and fish fed with diet 15FM showed best growth. The development of the digestive system did not suffer damage from the diets offered. Post-larvae fed the 30SPC diet showed reduced development of the digestive tract. The diet 15FM provide good lipid profile for silver catfish post larvae.

O câncer ocorre quando o aumento das células do corpo estão fora de controle e por consequência a quimioterapia é um dos tratamentos mais utilizados para o domínio sistêmico da doença, uma vez que essa alternativa está sendo muito relevante no combate à doença de forma singularizada ou combinada, porém, é capaz de causar no indivíduo fragilidade física e emocional de forma vultosa. Trata-se de uma pesquisa bibliográfica de abordagem qualitativa, com o objetivo de descrever o enfrentamento do paciente oncológico. Após a associação de todos os descritores, foram encontrados 151.280 artigos, excluídos 151.266 e selecionados 14. Perante as contribuições da enfermagem, é necessário identificar as fundamentais particularidades de cada paciente, para uma contribuição de modo integral e resultados terapêuticos eficientes. Posterior à leitura reflexiva emergiram duas categorias: Contribuições da enfermagem no enfrentamento do paciente oncológico diante da quimioterapia e Ótica do paciente oncológico frente a quimioterapia. A enfermagem tem papel fundamental diante dos paradigmas que permeiam o enfrentamento do indivíduo acometido pela doença oncológica, visto que na maioria dos casos o doente necessita primordialmente de apoio assistencial. Conclui-se que é de extrema relevância que se avalie os principais fatores que podem contribuir para o sofrimento do paciente oncológico diante do tratamento à base de quimioterápicos, para um melhor desempenho profissional e qualidade da assistência prestada ao doente.
