Published: January 2021

Introduction: Desmoid-type fibromatosis (DTF) is defined as a clonal proliferation of fibroblasts that emerges in soft tissues, with a tendency to infiltrate local tissues and toward local recurrence, but with no potential of distant metastases. The breast is an unusual location, corresponding to approximately 0.2% of all breast tumors. The literature has few DTF cases described in the male breast. The etiology of the lesion is unclear. Fibromatosis presents as a firm, painless, and mobile mass, which can be fixed to the pectoralis major or the skin. Radiological characteristics are nonspecific. The lesion manifests as a suspicious solid mass with irregular margins, making it difficult to differentiate the lesion from breast cancer on mammography, ultrasound, and magnetic resonance imaging. Immunohistochemistry (IHC) shows positivity for vimentin, ß-catenin, and actin, with negative desmin. Standard treatment consists of resection of the lesion with margins. Objective: To report a rare case of DTF in the male breast. Method: This is the description of the clinical case based on medical records. Result: A 42-year-old man had a nodule in the left breast for 1 year. He had no medical or family history of breast cancer. The patient presented a firm tumor with ill-defined margins, slightly mobile, adhered to the skin, measuring 5 cm, in the left upper inner quadrant during physical examination. Mammography showed asymmetry in the left breast, BI-RADS 4 Core biopsy indicated fibrosis, with segmental resection of the lesion. Histology revealed fibrous infiltrative neoplasm, with an intense collagenic aspect, 3.5 cm, and free margins. IHC was positive for vimentin, actin, and β-catenin, compatible with DTF. Conclusion: DTF in the male breast is a rare, locally invasive, benign tumor. It presents suspicious clinical and radiological aspects similar to those of breast cancer. The main treatment consists of resection of the lesion with satisfactory margins.

Published: January 2021

Introduction: Atypical ductal hyperplasia (ADH), atypical lobular hyperplasia (ALH), lobular carcinoma in situ (LCIS), and flat epithelial atypia (FEA) are part of a heterogeneous group of lesions with uncertain malignant potential and varying rates of malignancy after wide excision. They represent a clinical challenge, given the lack of well-defined approach recommendations. Objective: To determine the local rate of "upgrade" to malignancy (invasive carcinoma or in situ) after wide excision of ADH, ALH, LCIS (classic lobular neoplasia) diagnosed by percutaneous vacuum-assisted biopsy performed only in suspicious calcifications, as well as analyze radiological and histopathological parameters that can be associated with a higher risk of "upgrade". Material and Methods: This is a retrospective analysis of 117 patients diagnosed with ADH, LCIS, and FEA after percutaneous vacuum-assisted biopsy of suspicious calcifications, from 2015 to 2018. We evaluated radiological parameters – lesion size, morphology of the calcifications, diameter of the needle, and presence of residual calcifications – and histopathological parameters – extension of atypia (focal or multifocal) and association with other atypias. Results: Among the 106 patients included, 77 (73%) underwent surgery, with a rate of "upgrade" to malignancy of 19.5% (10 ductal carcinomas in situ, of which 30% had high grade) and 5 had invasive carcinomas (4 ductal and 1 tubular, all with low grade). In the subgroup analysis, the rate of "upgrade" was 31% for ADH, 14.7% for FEA, and 7.7% for LCIS. Needle diameter (9Gx11G) (p=0.48), presence of residual calcifications (less than 90% of the cluster removed) (p=0.73), and mean cluster extension (calculated based on the original mammography) (p=0.66) showed no statistically significant correlation with an increase in the rate of "upgrade". Amorphous calcifications predominated (60%), followed by fine pleomorphic ones, with rates of "upgrade" of 11% and 35%, respectively. Regarding histological parameters, we found no statistically significant difference between groups with focal (up to 2 foci) and multifocal atypia or association with other atypias. Conclusion: Our rate of "upgrade" to malignancy was similar to that of the published literature, and we found no statistically significant radiological or histological criteria for a greater risk of "upgrade".

Introduction: Breast cancer is the most common cancer in women worldwide. In Brazil, according to INCA, it had an incidence of 57,900 new cases in 2018, 16,340 cases in the state of São Paulo. The WHO classifies tumors according to morphological criteria, including non-special breast cancer (CMI-SOE), which is seen in 70% of cases, with more than 20 other special histological types, among which invasive lobular carcinoma (ILC) has a higher prevalence (10‒15%). Objective: To describe the histological profile of breast cancer patients at the Pérola Byington Hospital between the years 2009 to 2019. Method: Cross-sectional, descriptive study, obtained through a database review. It included patients with suspected invasive neoplasms seen at the service. Results: During the period, 10,539 patients with malignant lesions and ductal carcinoma in situ (DCIS) were treated, among those who had cancer, 91% were CMI-SOE, 5% lobular neoplasia, and 3.95% of the other special subtypes. The least frequent type was metaplastic, with only 20 cases in the period. In addition, 7.14% of the patients seen had DCIS. Conclusions: It is possible to observe the predominance of CMI-SOE in this series, as well as described in analyses carried out throughout the country and in the world, followed by lobular carcinoma and other special subtypes.

Introduction: Hereditary breast cancer represents about 10% of breast cancer cases. Risk factors for hereditary breast cancer are family history of breast cancer, ovarian cancer, breast cancer in men, among others, especially at an early age and bilateral tumors. Several hereditary syndromes have been described in relation to breast cancer, the most frequent being the Breast, Ovarian and Pancreatic Cancer Syndrome, determined by mutations in the BRCA 1 and 2 genes. In Brazil, the difficulty of accessing the genetic test of the public and private systems is still a reality, mainly due to elevate costs. Objectives: To raise patients' adherence to perform the BRCA test or multigene panels after medical recommendation at a private clinic in Piauí. Method: This is a retrospective study, evaluating medical records of patients seen in the period from 1999 to 2019. This study included all patients who had a recommendation to perform the BRCA mutation research or multigene panels. The study was approved by the ethics and research committee of Universidade Federal do Piauí, Opinion n. 2.817.502. Results: 164 patients who had a recommendation for genetic testing were studied. There were 162 female patients (98.7%) and mean age was 48.3 years. As for the presence of cancer, breast cancer was the most frequent one with 82 (79.6%) cases; as for survival, 5 (3.0%) of the cases evolved to death. 86 (52.4%) of the patients underwent the test, with mean gap between the recommendation and the test itself of 2.3 years. Of those who performed the tests, 23 (26.7%) had mutations in the BRCA gene, 15 (65.2%) in BRCA1, and 8 (34.8%) in BRCA2. Conclusions: 52.4% of the patients recommended for genetic testing performed the research. Of those who performed the tests, 26.7% had mutations in the BRCA gene, 65.2% in BRCA1, and 34.8% in BRCA2.

Background: Breast cancer is the second most common malignancy in female patients, thus becoming an important topic for public health. The current Gail model, already validated for other populations (e.g. White, African American, Native American, Asian), has been applied in other regions (e.g. Turkey, Qatar, Iran, Korea), however, without reflecting the ethnic diversity that the Brazilian population brings with it, through the intense miscegenation that occurred over centuries of civilization after the arrival of the Portuguese. Mobile applications are also part of the clinical practice, helping and streamlining clinical decisions, bringing benefits to healthcare professionals and patients. Objective: To translate, culturally adapt, and validate a tool for estimating the risk of developing breast cancer and to create an application for calculating the risk of developing breast cancer. Methods: Translation of the tool available on the National Cancer Institute (NCI) website from English to Portuguese (including backtranslating). Cultural adaptation through a questionnaire consultation with mastologists. Validation of the tool in a prospective observational study conducted through an interview, using the translated tool. Patients who were users of the Brazilian Unified Health System (Sistema Único de Saúde – SUS) were approached at the special clinic of Hospital Samuel Libânio, Pouso Alegre, Minas Gerais. Patients with a history of Lobular or Ductal Carcinoma in situ were interviewed, as well as those with mutations in the BRCA1 and BRCA2 suppressor genes and other hereditary syndromes associated with an increased risk of breast cancer (e.g. Cowden Syndrome , Li Fraumeni Syndrome). The risk of developing breast cancer over 5 years and throughout life has been calculated. Result: It is observed that 61.9% of the evaluating professionals were females, with a mean age of 35.9 years (SD=7.1 years), 76.2% were white, 95.2% were specialized in Mastology, and 66.7% had from 1 to 5 years of experience in the area. It is also observed that 100% attended the screening and 85.7% said they had no difficulty in identifying the risk factor. The mean age of the patients submitted to the interview was 49.9 years (SD=13.4 years), with a minimum age of 35 years and a maximum of 79 years. 62.5% of women were white, 50% had their menarche between 12 and 13 years old, 31.3% had their first term pregnancy before the age of 20 and 56.3% did not report first-degree relatives with breast cancer. The risk calculated using the tool for eligible patients was 1.3% over the next five years (Standard Deviation±0.86) and 12.41% over life (Standard Deviation±8.72), with no significant difference compared to the general population. Conclusion: The tool has been translated, culturally adapted, and validated according to international protocols for successful tool validation. The application for Android platform was developed.

Published: January 2021

Objective: To evaluate the association between metabolic syndrome (MS), obesity, and central fat deposition with the immunohistochemical profile (IHC) of breast cancer (BC) in postmenopausal women. Methods: A comparative cross-sectional clinical study was carried out with 63 women with recent BC and MS, compared to 126 women with recent BC, without MS (control group). Inclusion criteria were: women aged 45-75 years, amenorrhea >12 months, without previous cancer treatment, attended at a University Hospital. The groups were matched for age, time since menopause, and body mass index (BMI), in the proportion of 1 case for 2 controls, according to the sample calculation of at least 186 women in their entirety. Clinical and anthropometric data were collected; tumor size and grade and the IHC profile (ER, PR, HER2, and Ki67). By IHC convention, tumors were grouped into five subtypes: Luminal A (ER+, PR+, HER-2 -, and Ki-67 <14%); Luminal B HER-2 - (ER+, PR+ or -, HER-2 -, and Ki-67≥14%); Luminal B HER-2+ (ER+, PR+ or -, HER-2+, and any Ki-67); Non-luminal HER-2 (ER-, PR-, HER2+, and any Ki-67); and Triple-negative (ER-, PR-, HER2-, and any Ki-67). Women with three or more diagnostic criteria were considered with MS: waist circumference (WC)>88 cm; TG≥150 mg/dL; HDL cholesterol<50 mg/dL; blood pressure ≥130/85 mmHg; glucose ≥100 mg/dL. For statistical analysis, the Student’s t-test, Gamma Distribution, χ2 test and logistic regression (odds ratio–OR) were used. Results: Among the participating women, the mean age, time since menopause and BMI were: 59.0±10.6 years, 11.4±9.6 years, and 28.5±5.5 kg/m2, respectively; there was no statistical difference in the comparison between the groups. Women with MS had a higher occurrence of tumors ≤2cm when compared to those without MS (49.2 vs. 31.8%, respectively) (p=0.038). Women with MS had a higher incidence of tumors with PR-positive (p=0.046), HER2-negative (p=0.038), when compared to women without MS (79.4 vs. 65.8% and 44.5 vs. 27.8%, respectively). In obese patients (BMI≥30 kg/m2), a higher proportion of HER2 negative tumors (p=0.047) was observed when compared to non-obese women (43.9 vs. 27.7%, respectively). In the multivariate analysis, a higher risk for tumors of the Luminal B HER-2 negative subtype was observed among women with MS (OR 2.00, 95%CI 1.03‒3.89), obese (OR 2.03, 95%CI 1.06‒3.90), and with central deposition of fat (OR 1.96, 95%CI 1.01‒4.03). Conclusion: Metabolic syndrome, obesity, and central fat deposition correlate with factors of good prognosis for breast cancer, such as tumors ≤2 cm, PR+ and HER2-, in postmenopausal women.

Introduction: QT NEO starts from the premise of tumor downstaging, enabling excision of previously unresectable tumors, reducing surgical extension and, consequently, enabling higher rates of conservative surgery. It also allows an in vivo assessment of the neoplastic response to systemic therapy. PCR is a powerful indicator of the benefit of QT NEO and is associated with better outcomes for relapse, DFS and OS. Objectives: This study aimed to evaluate the pathological response rate of patients with CM HER2 who underwent QT NEO, treated at HCP in the years 2014-2016 and to correlate with the recurrence rates, DFS and OS, observing whether the data are in agreement with those reported in the literature. Methods: The study evaluated patients with BC HER2, confirmed by IHC and/or FISH, who underwent QT NEO followed by surgery from 2014 to 2016, treated at the HCP. It is a retrospective, observational, and descriptive study. The information collected comes from a questionnaire formulated by the researcher with the relevant points to be analyzed in the project. The data were stored and analyzed using SPSS, version 20.0. The Kolmogorov-Smirnov test, χ2 test or Fisher’s exact test were used to assess the variables. The DFS and OS time data were represented by the Kapplan-Meier curves and the Logrank test was used to verify a significant difference between the categories with or nPRC. A significance level of 5% was assigned to it. Results: The medical records of 58 patients with BC subtype HER 2 who received QT NEO followed by surgery were analyzed. During a mean follow-up of 35 months, 5 (8.6%) local recurrences and 20 (34.5%) distant ones and 18 deaths from breast cancer (31%) were observed. A result of 50% of PRC was achieved, with no correlation of statistical significance between age, histological type, nuclear grade, staging prior to QT NEO and chemotherapy regimen used. The PRC group achieved lower recurrence rates (20.68 vs. 51.72%) with statistical significance. DFS in the PRC group is 75.9% and in the nPRC group it is 44.82%. OS of the group with PRC is 82.7 vs. 48.2% in the nPRC group. Patients with HR- and PRC were the ones that most benefited from obtaining PRC in the recurrence and DFS outcomes, reaching recurrence rates of 22% and DFS of 77.8% compared to the HR group – without PRC, which had recurrence rates of 72% and DFS of 27.3%. Conclusion: This study found significant data with lower recurrence rates and better rates of DFS and OS in patients who achieved PRC, thus evidencing the impact that PRC has on long-term outcomes, especially in the HR- subgroup of patients.

As part of 21st-century skills, communication is an essential skill for students. Students 'mathematical communication tends to below, one of which is influenced by students' self-confidence. For this reason, the purpose of this study is to describe the mathematical communication skills in solving circle problems based on students' self-confidence. Determining the subject using purposive sampling technique, namely from 36 students of class VIII SMP in Madiun, East Java, Indonesia, obtained two subjects with high self-confidence (SCT) and one subject with low self-confidence (SCR). A qualitative descriptive approach was used in this study. Tests and interviews were used as data collection techniques. Data were analyzed through reduction, presentation, and concluding. The results of this study include: SCT is capable while SCR is less able to meet the indicators of mathematical communication skills both in writing and orally at the stages of understanding problems, implementing plans, and checking back; and SCT can meet mathematical communication indicators both written and oral, while SCR is less able to meet written mathematical communication indicators but can verbally at the stage of planning completion. The level of self-confidence of students differentiates their mathematical communication skills in solving problems. Thus, a teacher needs to design an appropriate question to train students' mathematical communication skills with low self-confidence.

The national exam results show that students still have difficulty solving PISA standardization questions, reinforcing the reason why Indonesian students' mathematical literacy scores on PISA are still very low. This mathematical literacy is part of the mathematical thinking ability, so building it will impact students' mathematical literacy. The comprehensive mathematics instruction (CMI) model is thought to build students' mathematical thinking abilities. This study aims to describe students' mathematical thinking achievement who obtain learning with the CMI model. Besides, this study also analyzed the achievement of students' mathematical thinking through the CMI model by paying attention to the prior knowledge of mathematics (PAM). This research is a quasi-experimental study. Samples were taken purposively from the population of high school students in Subang. The results showed that the achievement of students' mathematical thinking through the CMI model differed significantly from students' mathematical thinking abilities through conventional models. The difference in the achievement of generalizing, conjecturing, and convincing abilities between students who get CMI model learning and those who get conventional model learning occurs in students with moderate PAM. Thus, the CMI model is effective for building students' mathematical thinking abilities.

Spatial ability is one of the essential abilities to be mastered by students, especially in geometry. There is not much research, especially in Indonesian, that examines students' spatial abilities and their relation to Descriptive Geometry. This study aims to analyze students' misconceptions in the Descriptive Geometry course and describe the profile of students' spatial abilities in online learning during the COVID-19 pandemic. This study's subjects from the Mathematics Education Department of Universitas Negeri Jakarta. This research is descriptive qualitative. The learning was carried out in 16 meetings with three initial meetings offline, and the next 13 meetings online. The test was given twice at the 8th and 16th meetings accompanied by interviews with students who made mistakes in taking the test. The test results showed that students who made mistakes did not have the ability to spatial perception, spatial relation, and spatial orientation. However, there was a case of students who made mistakes still having the ability to spatial perception, spatial relation, and spatial orientation. The obstacles that affect students' spatial abilities are online learning that is not supported by technical matters, namely: limited internet networks and internet quota availability.

One of the cognitive skills that students must have is problem-solving ability. Therefore, a standardized test is needed to measure this ability. However, until now, the tests used to measure mathematical problem-solving ability were not standardized. This research aims to develop a valid and practical mathematical problem-solving test in the discussion of triangles and rectangles. This research is part of the R&D 4D type with steps: Defined (analysis to develop a test), Design (designing a problem-solving test form), and Develop (expert judgment and small group trials). The instrument in this research was the validation sheet used by the validator to assess each test item. The data analysis technique used the Aiken method for expert judgment and qualitative descriptive for development testing. The result is a valid and practical mathematical problem-solving test because the V-Aiken value is more than 0.532. Based on this, the instrument can be used to measure the mathematical problem-solving ability of junior high school students in the discussion of triangles and rectangles.

Published: January 2021

O presente trabalho visa abordar as formas pelo qual o estágio supervisionado direcionado à observação da escola e da atividade docente contribuem para a formação de um professor de biologia. Os resultados pautam-se nas observações realizadas nas aulas de ciências em duas turmas de 6º ano e nas aulas de biologia em também duas turmas de 1º. As escolas pelo qual foram realizadas as observações localizam-se no município de Teresina/PI. No decorrer do período de estágio foram observadas as metodologias de ensino utilizadas pelas professoras, os recursos didáticos usados pelas mesmas e a relação professor-aluno das turmas. As observações realizadas, inclusive sobre a infraestrutura de cada uma das escolas, foram discutidas com fundamentação teórica. No decorrer da disciplina de estágio supervisionado foram realizados dois projetos pedagógicos com o objetivo de averiguar se de fato os alunos compreenderam alguns conteúdos que outrora já haviam sido abordados pelas professoras. Os resultados mostraram que embora os temas já tivessem sido trabalhados pelas professoras e que avaliações sobre os conteúdos já tivessem sido realizadas, ainda sim os alunos mostraram grandes dificuldades. Ao final do período de estágio pôde-se concluir que a conciliação entre teorias educacionais e prática docente é de extrema complexidade e que inovar nas metodologias de ensino é crucial para a construção dos conhecimentos dos alunos.

Avaliando-o nível de atividade física, através sistema de avaliação SOFIT e relacionando os resultados com os embasamentos teóricos, obtendo assim o verdadeiro papel da pratica da Educação Física no desenvolvimento da socialização entre os alunos. Relacionando a importância das aulas de Educação Física e a aplicabilidade de atividades que trabalhem as relações interpessoais tornando os alunos mais ativos e principalmente formando cidadãos conscientes e autônomos, através da prática da atividade física. Percebe-se a pouca participação e interesse pela pratica das aulas de Educação Física no Ensino Médio, devido à falta de atividades que estimulem os alunos. No estudo destaca-se a abordagem do método Quanti-Qualitativa, Exploratória e observacional, na qual foram observados (15 meninas e 15 meninos) de uma escola de Ensino Médio da cidade de Itapeva/SP, sendo as mesmas avaliadas através do sistema SOFIT. Verificou-se quanto ao comportamento dos alunos uma baixa proporção de escolares que participam das aulas de Educação Física de forma ativa com cerca de (40%), sendo que permaneceram deitados (20%), sentado (93,3%), em pé (63,3%) e caminhando (63,3%). Já no quesito sobre os contextos trabalhados em aulas os resultados indicaram mais a pratica de jogos (73,3%) e outros contextos (33,3%). Quanto ao comportamento do professor às aulas ocorriam em gerenciamento (13,3%), observação (86,7%) e outras tarefas (60%). Conclui-se que poucos alunos de Ensino Médio da escola pesquisada praticam atividades físicas regulares, devido à falta de aplicação de conteúdos e atividades que instiguem a participação nas aulas. O professor se faz muito importante na criação, aplicabilidade e interferência das atividades trabalhadas em aula, levando o aluno a participar e se relacionar construindo de acordo com o tempo gosto pela pratica de atividade física regular, principalmente quando se fala de alunos que logo vão se incluir na sociedade adulta.

Este trabalho insere-se no campo da educação e da diversidade, em especial no que tange as questões referentes aos povos indígenas brasileiros. Tem como objetivo discutir os equívocos que atravessaram a história dos povos indígenas, a partir da sua colonização, bem como as lutas que travaram e as conquistas que tiveram no decorrer dos séculos, inclusive quanto a educação escolar. A metodologia adotada pauta-se no estudo bibliográfico, perpassando por estudos de documentos legais que garantem aos indígenas o direito como cidadãos brasileiros, conforme a Constituição Federal Brasileira de 1988, o direito a educação escolar diferenciada conforme a Lei de Diretrizes e Bases de 1986, dentre outros dispositivos que ampliam o respeito por sua cultura, língua e modo próprio de aprendizagem. Espera-se que as discussões aqui feitas contribuam para que os equívocos, referentes as histórias dos indígenas, sejam desconstruídos e para que instigue novas discussões e aprofundamentos acerca da temática.

O contexto lúdico que envolve a educação em artes, principalmente na linguagem teatral, trás para a criança a possibilidade de vislumbrar e vivenciar descobertas sociais e culturais híbridas, promovendo a troca de experiências e o respeito. Assim, o objetivo dessa pesquisa teórica é relatar a criação dos jogos teatrais e dos jogos dramáticos, além de discutir como estes podem ser utilizados em sala de aula para promover o ensino das metodologias de teatro, integrado com outras linguagens da Arte, a fim de experimentar e expandir diferentes possibilidades para o ensino/aprendizagem e o desenvolvimento do indivíduo. Para isto foi realizada uma pesquisa teórica em livros, dissertações e artigos científicos que trazem informações sobre a metodologia de Viola Spolin, Peter Slade e sobre o ensino de teatro. Como resultados conseguimos desenvolver um panorama histórico da criação dos jogos teatrais e jogos dramáticos, além de elucidarmos a sua utilização na educação infantil. A partir disso, verificamos a importância da educação integrada e participativa dos alunos, que gera oportunidades para a criança experienciar situações que possibilitam a construção de diferentes conhecimentos e de desenvolver várias habilidades, como expressão verbal, gestual, corporal, criatividade, intuição, espontaneidade e interação social.
A Revista Bem-Te-Vi e a educação para os indígenas na reserva de Dourados/MT na primeira metade do século XX

Published: January 2021

O projeto de civilização e educação desenvolvido pelos missionários protestantes na primeira metade do século XX para as etnias, Kaiowá, Guarani e Terena da Reserva Indígena de Dourados (RID), região Sul de Mato Grosso (MT), contou com a circulação da revista metodista Bem-te-vi, a partir de 1922. Assim, o artigo analisa a educação ministrada aos indígenas nesse período com base nos conteúdos abordados na Revista, buscando relacionar o projeto de educação à teoria positivista. Para compor as análises realizadas neste texto, foi preciso recorrer a documentos do Posto Indígena Francisco Horta, disponíveis nos arquivos do Museu do Índio do Rio de Janeiro, ao jornal protestante O Estandarte, disponibilizado para consulta online e a revista Bem-te-vi. Os resultados apontaram que a imprensa evangélica contribuiu com o projeto de educação, evangelização e “civilização” direcionado aos indígenas, por meio de conteúdos. Assim, podemos constatar que essa imprensa priorizava a formação de sujeitos cristãos e civilizados, alcançando desse modo, o estado de desenvolvimento.

Sosiaalityöntekijät työskentelevät nuorisopsykiatriassa erityistyöntekijöinä tuoden sosiaalista näkökulmaa moniammatilliseen vuoropuheluun. Nuorisopsykiatriassa on viime vuosina kehitetty hoitomalleja. Samalla erityistyöntekijöiden työnkuvaa on pyritty vahvistamaan. Artikkelissa sosiaalityön psykososiaalisen asiantuntijuuden jäsentymistä tarkastellaan nuorisopsykiatrian avohoidon monialaisessa ja muuttuneessa toimintaympäristössä. Tutkimuksen aineisto koostuu nuorisopsykiatrian ammattilaisille järjestetyistä fokusryhmähaastatteluista. Nuorisopsykiatriassa psykososiaalinen sosiaalityö jäsennetään kaksoisroolina, joka koostuu nuoren sosiaalisen toimintakyvyn ja perheen kokonaistilanteen arvioimisesta ja palveluverkoston koordinoinnista sekä terapeuttisesta työstä. Ammattiryhmien haastatteluissa korostui yhteisesti näkemys siitä, että lähtökohtana sosiaalityöntekijän asiantuntijuudelle nuorisopsykiatriassa on ymmärrys psyykkisten oireiden vaikutuksesta nuoren sosiaaliseen toimintakykyyn.
The political economy of unsustainable lock-ins in North American commodity agriculture: a path forward – Response to Struckman
Authors: Secchi Silvia
Published: January 2021

In this commentary, I argue that in North America, the overuse of synthetic nitrogen fertilizer is due to institutional and technological lock-ins, which are the result of historical policies with deep roots in an agricultural system focused on increasing production of commodities with disregard for their full social costs. Further, excessive fertilizer use is integral to production systems that have disconnected crop and livestock production to the extent that manure is a waste product, which further creates environmental problems. In order to address the environmental and social problems associated with industrial agriculture, it will be necessary to bring market prices closer to true social costs, thereby eliminating overproduction of commodity grains and oilseeds, and to promote more diverse agricultural landscapes.

Published: January 2021

This paper presents the research on reliability of high-speed radial marine diesel engine Zvijezda M 504 B2 based on experimental data of malfunctions on the engine and time required for repair. Exploitation reliability and failure intensity were calculated from operational data collected from the engine log book. Results were tested by computer program to determine the relevance of the obtained results. Mathematically calculated reliability model of high-speed radial marine diesel engine Zvijezda M 504 B2 showed continuous increasing function of the intensity of failure and the fact that the reliability of the engine can be reliably approximated by Weibull distribution. Based on the obtained results it has been shown that this distribution, regardless of its complexity, should be used in practice when calculating reliability of engines with similar constant and growing malfunction’s intensity. The conclusion is that proposed distribution enables a better depiction of the observed technical system and the impact of aging of components on the system reliability.

Analysis and determination of the most promising and economical plasma technologies for processing polymeric textile materials to obtain materials with specifi ed properties. Methodology. The article uses analytical methods for the study of diff erent types of plasma treatment of polymeric textile materials and their impact on the properties and structure of these materials. Results. Diff erent types of plasma treatment of polymeric textile materials are analyzed. Of the physical methods of modifi cation, the most promising are plasma technologies that can reduce environmental pollution. Thermal plasma has extremely high temperatures and cannot be used to modify and treat the surface of PTM fi bers. The choice of a certain type of cold plasma for the treatment of PTM depen ds on the speed of their processing, the sample size and the degree of the proposed modifi cation. The infl uence of diff erent types of plasma treatment of polymeric textile materials on the change of their structure and properties, as well as the causes and features of such changes are determined. Practical value. The application of plasma technologies in the textile and light industry allows to replace the technological operations of processing polymeric textile materials that require high consumption of water and chemical reagents, for the processes of their dry processing. This reduces the consumption of chemical materials and reduces energy costs. Installation and maintenance of atmospheric pressure equipment is much simpler and cheaper than low pressure plasma equipment
