Projeto 500: desafios da inclusão de estudantes negros numa universidade pública de pesquisa nos Estados Unidos, 1968-2018
Authors: Oliven Arabela Campos
Published: January 2020

Resumo O artigo analisa uma política de inclusão de estudantes negros em uma importante universidade pública de pesquisa nos Estados Unidos, desde o período em que foi implementada, através do Projeto 500, no final da década de 1960, até os dias atuais. Levam-se em conta relações raciais e peculiaridades do sistema de educação superior norte-americano na contextualização dessa política de ação afirmativa. Examina-se o modo como um grupo historicamente discriminado em instituições de educação superior que formam a elite branca do país questiona não apenas a organização interna da instituição, mas também a relação universidade e sociedade.

Published: January 2020

Abstract Introduction Experiencing trauma may entail psychopathological consequences, but also changes considered to be positive (i.e., posttraumatic growth). For positive change to occur, an impact on the beliefs of individuals is required, which may be measured through the Core Beliefs Inventory (CBI). The objective of this study was to validate the Brazilian Portuguese version of the CBI. Methods A total of 248 university students (65.7% female) answered the following assessment instruments: sociodemographic data sheet, Posttraumatic Growth Inventory (PTGI), Posttraumatic Symptoms Checklist – Clinician Version (PCL-5) and the CBI. Psychometric properties of the CBI were assessed by conducting an exploratory factor analysis through a principal component analysis with varimax rotation. Internal consistency (Cronbach’s α) and convergent validity (Pearson correlation between instruments) were also investigated. Results The total scale showed adequate internal consistency (α = 0.83). A single factor solution explained 42.63% of the variance of the CBI. Significant correlations were found between CBI and PTGI, and between CBI and PCL-5. Conclusion The psychometric properties indicated adequate internal consistency and construct validity of the Brazilian Portuguese version of the CBI.

Abstract Introduction To improve the comprehension of the interface between smartphone addiction (SA) and Facebook addiction (FA), we hypothesize that the occurrence of both technological addictions correlate, with higher levels of negative consequences. Moreover, we hypothesize that SA is associated with lower levels of social support satisfaction. Methods We recruited a convenience sample of undergraduate students from Universidade Federal de Minas Gerais, with age ranging between 18 and 35 years. All subjects completed a self-fulfilled questionnaire comprising sociodemographic data, the Brazilian Smartphone Addiction Inventory (SPAI-BR), the Bergen Scale for Facebook Addiction, the Barrat Impulsivity Scale 11 (BIS-11), the Social Support Satisfaction Scale (SSSS), and the Brief Sensation Seeking Scale (BSSS-8). After completing the questionnaire, the interviewer conducted a Mini-International Neuropsychiatric Interview (MINI). Results In the univariate analysis, SA associated with female gender, with ages 18 to 25 years, FA, substance abuse disorders, major depressive disorder, anxiety disorders, low scores in SSSS, high scores in BSSS-8, and high scores in BIS. The group with SA and FA presented a higher prevalence of substance abuse disorders, depression, and anxiety disorders when compared to the group with SA only. Conclusion In our sample, co-occurrence of SA and FA correlated with higher levels of negative consequences and lower levels of social support satisfaction. These results strongly suggest that SA and FA share some elements of vulnerability. Further studies are warranted to clarify the directions of these associations.

Abstract Introduction Few studies have used eye tracking as a screening tool for autism spectrum disorder (ASD) in preterm infants. Objectives To evaluate fixation time on social and non-social figures and percentage of preterm babies who gazed at the images. Methods This was a cross-sectional study of 31 preterm infants born weighing ≤ 2,000 g in which eye gaze was evaluated at 6 months of corrected age. Six boards with social and non-social figures were projected on a computer screen, successively, evaluating time and percentage of preterm babies who gazed at each board. The Modified Checklist for Autism in Toddlers (M-CHAT) was answered at 18 months of corrected age. Results Preterm infants showed longer visual fixation time on social figures compared with non-social images, regardless of the position of the social figure on the board. Similar percentages of preterm infants gazed either at social or non-social figures, at social figures with a direct or an indirect look, and at the eyes or mouth of the social figures. No preterm infant screened positive on the M-CHAT. Conclusion At 6 months of corrected age, preterm infants show the ability to gaze in an eye-tracking test, with preference for social figures, suggesting that this tool could be useful as another screening instrument for ASD.

Abstract Introduction Child suicidal behavior is related to specific childhood variations, constituting risk factors, including predisposing factors, internal factors, and environmental factors. Objective To characterize suicidal behavior among children aged 5 to 12 years diagnosed with a depressive episode. Methods Fifteen participants, aged 5 to 12, were assessed at a child and adolescent mental health center in Belo Horizonte, state of Minas Gerais, Brazil. All participants had a history of suicide attempt and were in a depressive episode at the time of assessment. Results Vulnerabilities related to the children themselves were self-harm, aggression, loss of an important family figure, sexual abuse, sexuality disorders, use of alcohol or other drugs, and ill-treatment. Factors of family structure and dynamics found were psychiatric illness in family members, family conflict or violence, abandonment or rejection, history of suicidal behavior in family, parents users of alcohol and other drugs, and separated parents. Factors related to school were bullying, school difficulties/delays, high school performance, bad behavior, physical aggression, school dropout, and aggressiveness. The main methods used in suicide attempts were injury by sharp or blunt objects and intentional self-poisoning. Conclusions Psychiatric comorbidities and a previous history of disturbances in the family and at school are important factors to consider with relation to suicidal behavior by children with depressive episodes.

Published: January 2020

Abstract Introduction Although bipolar disorder (BD) is traditionally included among mood disorders, some authors believe that changes in energy and motor activity, rather than mood changes, represent the true cardinal symptoms in mania and depression. The aim of the current study was to identify which cluster of the Hamilton Depression Rating Scale (HAM-D) better distinguishes between mania, depression and euthymia. Method A group of 106 patients with BD were followed for 13 years and repeatedly assessed with the HAM-D as well as with other clinical scales. To perform a comparison, HAM-D items were classified according to clinical criteria into three clusters: energy/activity symptoms, mood symptoms, and other symptoms. Item response theory (IRT) analyses were performed to provide a test information curve for those three clusters. We measured the prevalence of one cluster of symptoms over the other two throughout the latent trait. Results Considering HAM-D items individually, the IRT analysis revealed that there was a mixture of mood and energy/activity symptoms among the most discriminative items, both in depression and in euthymia. However, in mania, only energy/activity symptoms – i.e., general somatic symptoms and retardation – were among the most informative items. Considering the classification of items, both in depression as in mania, the energy/activity cluster was more informative than the mood cluster according to the IRT analysis. Conclusion Our data reinforce the view of hyperactivity and motor retardation as cardinal changes of mania and depression, respectively.

Published: January 2020

Abstract Objective To identify which clinical features and personality traits are associated with quality of life (QoL) in panic disorder (PD) patients. Methods This was a cross-sectional study with PD patients. The brief version of the World Health Organization Quality of Life Questionnaire (WHOQOL-BREF) and the Big Five Inventory (BFI) were used to assess QoL and personality traits respectively. The strength of correlations was measured with Pearson’s, Spearman’s, and point-biserial correlation coefficients. We also performed multiple linear regressions, considering sociodemographic data and scores from clinical scales as independent variables and QoL scores as dependent variables. Results A total of 98 patients were evaluated. Depressive symptoms had a strong negative correlation with QoL and, to a lesser extent, panic and anxiety symptoms were also negatively correlated with QoL. While consciousness, extraversion, and agreeableness had mild positive correlations with QoL, neuroticism had a strong negative correlation. Conclusion Symptoms of depression, anxiety, and panic seem to have a negative impact on the QoL of PD patients. Personality traits, especially neuroticism, may also influence QoL in these patients.

Resumo O trabalho trata da aplicabilidade da Lei 11.645/2008, que determina a inclusão de História e Cultura Afro-Brasileira e Indígena nos currículos da Educação Básica, preferencialmente nas áreas de educação artística e de literatura e história brasileiras. Objetiva averiguar a aplicabilidade dessa lei quanto à obrigatoriedade do ensino de História e Cultura Afro-Brasileira e Indígena, em práticas de professores de História do Ensino Médio. Utilizou-se uma abordagem qualitativa e usou-se como técnica a entrevista semiestruturada. Os professores, historiadores entrevistados, atuam em escolas públicas estaduais em uma cidade do Estado do Rio Grande do Norte. Realizou-se uma reflexão a respeito dos processos de formação e capacitação desses docentes e dos impactos dessa lei em suas práticas de ensino. Os professores reconhecem a importância dessa legislação, mas não a consideram suficiente para provocar mudanças efetivas nas escolas, no sentido da superação de preconceitos enraizados em práticas sociais fortemente presentes em nossa sociedade. A exigência de conteúdos de História e Cultura Afro-Brasileira e Indígena na referida lei não garante sua aplicabilidade no ensino de História, diante de lacunas identificadas nos processos de formação inicial e continuada dos professores das escolas pesquisadas. É vital que os professores de História recorram, em suas práticas de ensino, à valorização da memória dos diversos grupos étnicos que compõem a nossa sociedade, como um instrumento de consolidação da cidadania e da democracia, o que demanda processos de formação docente nas universidades e nos espaços de atuação do professor.

Resumen El presente artículo tiene el propósito de presentar los resultados de una investigación que buscó establecer una línea de base que permitiera conocer desde la perspectiva de los estudiantes cuáles eran sus apreciaciones sobre el manual de convivencia, el desarrollo e implementación de la cátedra de la paz y la mediación de conflictos dentro de las instituciones educativas con el propósito de desarrollar una construcción de paz estable y duradera, entendida esencialmente como un proceso orientado por el Estado que busque promover buenas prácticas en el aula, formación docente de calidad y estructuras organizativas que favorezcan el aprendizaje de la ciudadanía en el contexto educativo. La investigación está enmarcada bajo el paradigma cualitativo, se realizaron entrevistas grupales semiestructuradas tipo grupo focal con estudiantes de los grados 9, 10 y 11, de diferentes instituciones educativas. Los resultados dan cuenta de la percepción que tienen los estudiantes en las dimensiones evaluadas, siendo relevante: que solo utilizan de manera instrumental el manual de convivencia, y no como fuente de formación; el desconocimiento de los contenidos de la Cátedra de la Paz y de su importancia para contribuir a la construcción de una cultura de paz y el uso por parte de los estudiantes de una autoridad vertical tradicional para resolver los conflictos.
Empatía histórica en futuros profesores de primaria: el trabajo infantil en el siglo XIX
Authors: Carril-Merino María Teresa , Sánchez-Agustí María , Muñoz-Labraña Carlos
Published: January 2020

Resumen En esta investigación se estudia la implicación del factor emocional en el desarrollo de la empatía histórica y, por tanto, en la comprensión histórica, en una muestra de 164 futuros profesores. Una cuestión que ha generado fuertes controversias entre los que reivindican el papel de los afectos en la empatía histórica y aquellos que los cuestionan. Para ello, se utiliza como estrategia una actividad de contrariedad sobre el trabajo infantil en el siglo XIX, donde el componente afectivo está fuertemente comprometido en la interpretación del contexto. Para cumplir con este objetivo se plantea una investigación desde el paradigma cualitativo mediante un proceso de interpretación de las narrativas de los informantes con la ayuda del software ATLAS.ti. La sistematización de las respuestas a la actividad de contrariedad se realiza en función de cuatro categorías progresivas, que van desde una adopción de perspectiva condicionada por el presente hasta la comprensión e, incluso, recreación de un mundo social diferente. Los resultados de la investigación presentan que tan solo un pequeño grupo de alumnos/as realiza explicaciones contextualizadas, frente al resto de participantes que en mayor o menor medida vinculan su interpretación histórica a un marco emocional presentista. Es posible concluir, pues, que el factor emocional, cuando vulnera el marco presente de valores, no parece favorecer la comprensión de las circunstancias históricas que explican el trabajo infantil en épocas pasadas.
A pesquisa em ciências humanas, ciências sociais e educação: questões éticas suscitadas pela regulamentação brasileira
Authors: Campos Regina Helena de Freitas
Published: January 2020

Resumo As diretrizes que regulam a ética na pesquisa com seres humanos no Brasil, em especial no que se refere às áreas das ciências humanas e sociais e às ciências da educação, são analisadas em suas relações com a bioética e as ciências da vida. As dificuldades levantadas por pesquisadores da área de humanas no diálogo com os comitês de ética interdisciplinares são consideradas, inclusive a possibilidade de desvincular a autorização da pesquisa nessas áreas do sistema CEPs-CONEP, sistema nacional de Comitês de Ética na Pesquisa gerido pelo Conselho Nacional de Saúde. Argumenta-se, contudo, que o foco principal do sistema da ética na pesquisa é a proteção da saúde física e mental dos participantes, o que configura uma questão afeita à bioética e à área da saúde, de maneira ampla, como processo biopsicossocial. Observa-se também que as técnicas de coleta de dados desenvolvidas pelas ciências humanas e sociais (entrevistas, questionários, observações participantes ou não) são também utilizadas pelas ciências da vida. Essas considerações indicam que o diálogo entre as áreas, propiciado pela composição de Comitês de Ética interdisciplinares, é salutar e necessário ao bom funcionamento do sistema, em que pese a possibilidade, admitida na legislação, da existência de comitês específicos para o julgamento da ética na pesquisa em ciências humanas e sociais. Propõe-se que novas pesquisas sejam feitas para o acompanhamento do funcionamento dos comitês de ética em universidades e instituições de pesquisa visando ao aprimoramento do sistema de regulação.
Sulfur-based polymers by inverse vulcanization: a novel path to foster green chemistry
Authors: Abbasi Amin , Nasef Mohamed Mahmoud , Yahya Wan Zaireen Nisa
Published: January 2020

The world is witnessing a growing interest in the utilization of waste materials to reduce environmental burden, add product value and promote sustainability. Such noble goals are being supported by the implementation of a number of approaches, including green chemistry. Currently, accumulation of large amounts of waste elemental sulfur, a by-product produced in gas and petroleum refineries, is posing an environmental concern and requires immediate intervention to search for new routes to make high-value materials from it. Inverse vulcanization is a new copolymerization technique allowing formation of stable sulfur-based polymers (sulfur copolymers) against the depolymerization of sulfur chains. Such a new class of polymers has demonstrated great properties for several environmental and renewable-energy applications. This paper reviews the advances in the evolution of sulfur copolymers prepared by inverse vulcanization with various monomers, including not only petro-based monomers but also renewable monomers as well as vegetable oils. Several applications of the obtained sulfur-based polymers are discussed. The challenges and future research directions to develop new polymers further and extend their applications are elaborated.
Concrete with rejected recyclable plastic waste at high temperatures
Authors: Camilo Jessica Regina , Rohden Abrahão Bernardo , Garcez Mônica Regina
Published: January 2020

The physical, chemical and mechanical properties of concrete incorporating rejected recyclable plastic waste (RRPW), the potential for the mitigation of heat-induced concrete spalling and the effects of high temperature on the residual properties of concrete were investigated. Concrete compressive and tensile strengths, Young's modulus, crack width, mass loss, water absorption by capillarity, chemical composition and evidence of heat-induced concrete spalling were monitored in concrete samples made with RRPW particles and compared with those of concrete samples made with commercial polypropylene (PP) fibres, after exposure to 200°C, 400°C and 600°C for 2 h. The use of 0·125% by volume of PP fibres and plastic waste particles was found to improve the heat-induced concrete spalling performance, due to the release of internal pressure after melting by different mechanisms. The positive effects on concrete properties show the technical potential of incorporating RRPW particles in construction materials.

The Impossibility of Client–Therapist “Match”: Implications and Future Directions for Multicultural Competency
Authors: Ertl Melissa M. , Mann-Saumier Michelle , Martin Renee A. , Graves Donald F. , Altarriba Jeanette
Published: January 2020

Extensive research has examined the influence of client–therapist racial, ethnic, or cultural match on outcomes in therapy. Further, many narrative reviews have summarized the literature in this area, and several meta-analytic reviews have examined the strength of the influence of client–therapist match. The present narrative review builds on previous studies by discussing several critical issues in this literature. In particular, we add to the extant literature reviews by contextualizing the challenges of defining and measuring client–therapist match given the possible broad range of diverse intersectional identities. As matching is not always possible, recommendations for working with clients of a different cultural background are discussed. Suggestions for multicultural competence training are included. We also provide a case example of how intersectionality of identities can inform the therapeutic context. The current article provides updated insights into the client–therapist match literature and emphasizes specific recommendations for education, training, and supervision.
Evidence-Based Relationship Factors: A New Focus for Mental Health Counseling Research, Practice, and Training
Authors: Parrow Kimberly K. , Sommers-Flanagan John , Cova J. Sky , Lungu Hugo
Published: January 2020

Counselor educators and mental health counselors often have a lukewarm attitude toward counseling research and evidence-based practice. This attitude may be because of a perceived mismatch between evidence-based technical procedures and the relational orientation that most counselors value. To warm up mental health counselors’ attitudes toward evidence-based research and practice, we propose a relationally oriented research agenda that focuses on integrating evidence-based relationship factors (EBRFs) into counselor training and practice. Eight EBRFs are defined and operationalized, and specific counselor behaviors are described. Reframing and refocusing counseling research on relational variables has the potential to support current counseling practices and inspire development of a counseling-specific research base. Recommendations for a rapprochement between counselor education research and mental health counseling practice are offered, including a list of brief measures that mental health counselors could introduce into their counseling practice.

Authors: Long Susan M. , Clark Madeline , Ausloos Clark D. , Jacoby Rachel , McGhee Carla
Published: January 2020

Poverty impacts holistic health and wellness, yet little research in counseling has been conducted exploring the holistic wellness and self-care of marginalized groups. Self-care and wellness are important components of overall mental health, and integrating strategies for self-care and wellness can support mental health counseling practice. A transcendental phenomenological design was used to explore and describe the wellness and self-care experiences of 10 single mothers in poverty. Data were collected using individual, face-to-face, semi-structured interviews, conducted for 45 to 60 minutes each. Major themes that emerged from the data include (a) barriers to wellness and self-care, (b) supports with wellness and self-care, (c) single mothers’ awareness of wellness and self-care, and (d) personal strengths of single mothers in poverty. Implications for clinical mental health counselors include utilizing strengths-based approaches, wellness, and advocacy interventions for single mothers in poverty.

Importance of the Internet in Illegal Migration and Migration Crimes Determination
Authors: Solovyev V. S. , Urda M. N.
Published: January 2020

The purpose of the paper is to identify the correlation between illegal migration, migration crimes and the use of the Internet resources. The content analysis of advertising sites, social networks in combination with other research methods has revealed that in the virtual space there is both active promotion of services facilitating illegal migration and a wide demand for them. Based on the results of the study, the authors develop the following proposals for improving measures to combat illegal migration in the global network. 1. A strategic direction for countering illegal migration should be the adjustment of the state’s migration policy through the establishment of a correlation between this phenomenon and the use of modern information and telecommunication technologies aiming at organizing and developing a criminal business providing illegal entry, stay (residence) services, fictitious registration, and registration on migration registration, etc. 2. The counteraction to illegal migration in cyberspace should be implemented through an integrated approach. From the perspective of criminal law, it is necessary to add the element “using the media or information and telecommunication networks (including the Internet)” into Part 2 of Art. 322.1 of the Criminal Code of the Russian Federation, which provides for liability for the crime elements of the organization of illegal migration. From the perspective of criminology it is important to identify and record the real conditionality of the development of illegal migration, migration crimes and the use of the Internet to commit them; to improve statistical reporting on crime by including information on the organization of illegal migration committed via the media or information and telecommunication networks (including the Internet) in the report of the State Automated Police Center of the Ministry of Internal Affairs of the Russian Federation on crimes committed in the field of telecommunication and computer information.
Superior mesenteric artery syndrome following spinal deformity correction
Authors: Strelnikova Angelina S. , Kozyrev Aleksandr S. , Vissarionov Sergei V. , Kartavenko Kirill A. , Murashko Vladislav V.
Published: January 2020

Background. Superior mesenteric artery syndrome is a rare pathological condition caused by an abnormal transposition of the superior mesenteric artery from the abdominal part of the aorta. It results in compression of the distal part of the duodenum between the aorta and the superior mesenteric artery. It is clinically manifested by signs of acute intestinal obstruction, including pain in the epigastric region, nausea, and profuse vomiting. In the absence of timely treatment, patients may experience electrolyte disturbance, severe nutritional deficiency, the risk of perforation of the stomach, aspiration pneumonia, bezoar formation, thromboembolism, and the development of other life-threatening complications that can lead to death.
Case study. In the presented case study, superior mesenteric artery syndrome developed in a 17-year-old girl after surgical correction of a spinal deformity in the treatment of idiopathic scoliosis. This was due to postoperative loss of body weight, as well as a rapid change in the patients ratio of growth to body weight.
Discussion. Significant clinical improvement was achieved as a result of an integrated approach to the treatment of this complication. However, despite the successful result from conservative therapy, the patient remains at risk of developing chronic duodenal obstruction of varying severity, which may require surgical treatment.
Conclusion. With the untimely and incomplete treatment of superior mesenteric artery syndrome, the risk of developing chronic intestinal obstruction increases. Treatment of this complication begins with conservative therapy. In the absence of the effect of conservative therapy, and in the case of disease progression, the development of life-threatening conditions (such as bleeding and perforation) requires surgical treatment.
A comparative analysis of the surgical treatment of preschool children with congenital spinal deformation and isolated hemivertebra from the combined and dorsal approaches
Authors: Vissarionov Sergei V. , Syundyukov Ayrat R. , Kokushin Dmitry N. , Khusainov Nikita O. , Khardikov Michael A.
Published: January 2020

Background. Currently, there are many studies on the evaluation of the results of surgical intervention and the comparative analysis of various surgical techniques for treating children with congenital spinal deformities. However, there is no consensus regarding the choice of surgical access to the abnormal vertebra that considers the duration of surgery, the volume of intraoperative blood loss, the degree of correction achieved during the intervention, the length of metal fixation, and the preservation of the result in the long-term observation period.
Aim. The goal is to identify the advantages and disadvantages of the dorsal and combined approaches to the surgical treatment of preschool children with congenital deformities of the thoracic and lumbar spine against the background of an isolated violation of the vertebral formation.
Materials and methods. A retrospective analysis of 56 patients under the age of five with congenital spinal deformities and a history of an isolated hemivertebra in the thoracic and lumbar regions who underwent one-stage hemivertebral extrusion from a dorsal approach (1st group: n = 30) or from a combined approach (2nd group: n = 26) was conducted.
Results. All patients showed improvement in the sagittal and frontal profiles of the spine. However, during separation in the first group of patients, a progression of the kyphotic component of the deformity in the lumbar spine from 19 to 8 was noted, while the correction value of the curvature of the scoliotic component remained stable. Intraoperative blood loss in the first group of patients was less (234 mL) compared with that in the second group (319 mL), while the duration of surgery was longer (310 min and 185 min, respectively). On average, in the first group, a longer metal structure was used to correct the spinal deformity compared with the second group.
Conclusions. The correction of the patients congenital spinal deformities with a single hemivertebra from a combined access approach allows a complete correction of the congenital curvature, the fixation of a smaller number of vertebrae, and the maintenance of a stable result in the long-term observation period compared with the dorsal approach. Isolated dorsal access to the hemivertebral body is characterized by less intraoperative blood loss compared with the combined approach, although the length of surgical intervention is increased.
Lengthening of the ulna by external fixation in children with congenital radial club hand
Authors: Avdeychik Natalia V. , Golyana Sergey I. , Grankin Denis Yu. , Safonov Andrey V.
Published: January 2020

Background. Congenital radial club hand is characterized by the radial deviation of the hand, the longitudinal underdevelopment of the forearm, and the dysfunction of the upper limb. The shortening of the ulna is observed in all types of congenital radial club hand. The average shortening of the ulna surgical treatment was 33.3% compared to the intact contralateral side.
Aim. This study aimed to evaluate the results of ulna elongation by the method of external fixation, depending on the level of osteotomy, in patients with congenital radial club hand type IIIIV.
Materials and methods. The treatment results of 36 patients with congenital radial club hand type IIIIV from 1998 to 2018 were analyzed. The average age of the patients was 7.4 years 3.5 years. The patients were divided into three groups, depending on the level of ulnar osteotomy. Shortening of the ulna, correction of the angle of deformity of the ulna, radial deviation of the hand, period of correction, elongation obtained, index of fixation and osteosynthesis, and associated complications were analyzed.
Results. The observation period was an average of 5.8 years. Before surgical treatment, the ulna was 33.3% shorter, while after surgery, it was 16%. Before surgery, the angle of deformation was 20.5 14.8, while after surgery, it was 7.4 5.6; this gives an angle of deformity correction of 63.9%. The elongation of the ulna was 3.2 1.1 cm. In patients who underwent proximal osteotomy, the resulting elongation was 32% and 18.4% more, respectively, than in patients who underwent an osteotomy in the middle and distal sections of the ulna. In group 1, the correction period was 24.4% and 28.9% more than in groups 2 and 3, respectively. The index of fixation in group 1 was 53.6%, which was 45.7% less than in groups 1 and 3. Postoperative complications included a false joint (15%), inflammation (10%), and forearm deformities (7.5%).
Conclusions. In patients with congenital radial club hand type IIIIV, the optimal part of an ulna osteotomy is the proximal section. With a hand deviation of more than 20, osteotomy is performed in the distal section with simultaneous correction of the deformity.

The analytical model of pulsed eddy current (PEC) serves as a tool to explore the detection mechanism of PEC testing, which is widely used to optimise the design of probes and analyse the influence on PEC signals. However, based on the analytical model of impedance change, the computational
efficiency of the PEC model for pipelines is low at present, which means that a lot of time is consumed and the application of the analytical model of PEC is suppressed. In order to improve the efficiency of numerical calculation, this paper proposes a fast numerical calculation method for
the analytical model of PEC for pipelines, based on the integral model of impedance change. Firstly, in order to improve the calculation efficiency of the Dodd and Cheng model, this paper reveals that the generalised integral can be changed into a definite integral by studying the properties
of the integral function. Secondly, according to the partial derivative characteristic of impedance change with frequency, the method of piecewise cubic spline interpolation is used to calculate the impedance change of harmonics. Finally, an analytical model of PEC for single-layer pipeline
is calculated and the results are compared with the finite element method (FEM) to verify the accuracy and efficiency of the proposed method. The results indicate that the method could be used to improve the computational efficiency of the PEC model for pipelines when only conductivity is
changed.

Site response at many locations in the central and eastern United States is a resonance-based phenomenon, which site factors based on the VS30 proxy may not reliably capture. Alternative factors, fundamental frequency, f0, and fundamental-mode amplification, A0, calculated from simplified expressions were evaluated against 1D linear, viscoelastic SH-wave full-resonance (FR) site responses. Tests were conducted using S-wave velocity profiles to bedrock at 11 seismic stations. The results showed that simplified expressions approximate FR f0 and A0 at most stations. However, at two sites with intermediate-depth strong impedance contrasts, the simplified approach underestimates A0 by ∼40%.

In addition, FR f0 and A0 were compared with weak-motion earthquake S-wave horizontal-to-vertical (H/V) spectral ratios. Measuring f0 and A0 from S-wave H/V for our comparisons required considering multiple observations at the regional scale. The first S-wave H/V peaks occurred between ∼1 and ∼3  Hz at all seven stations in the Illinois basin (IB), which is a much lower f0 than expected for five of these sites. Thus, we used the first S-wave H/V peaks at f>3  Hz at these five sites in our comparisons. The S-wave H/V peaks we evaluated indicate that S-wave H/V can approximate FR f0. However, although the A0 measured from S-wave H/V is positively correlated with theoretical A0, it overestimated FR A0 by more than 40% at all but three sites, indicating that additional study is needed to determine the appropriate use of A0 from S-wave H/V. The observed, unmodeled amplifications between ∼1 and ∼3  Hz are of similar magnitudes as those from the shallower sediment layers at most stations, which highlights the importance of collecting empirical site-response estimations. Furthermore, the amplifications indicate the need to investigate deeper velocity structures in the IB to account for site responses within the frequency band of engineering interest.

In this work, the impact of dyes and fillers on the process of heat generation during ultrasonic welding of plastics was studied, which made it possible to influence the weldability and quality of products. Experiments to weld samples of plastics with various concentrations of dyes and fillers were carried out. Based on the experimental data, it was established that the main parameters of the welding process and the properties of the polymer influenced weldability and performance indicators of the weld joint. The nature and the concentration of the dyes and fillers injected into the polymer to obtain certain characteristics and colors had an impact as well. Optimal concentrations that provided the best weldability, strength and quality of the weld products were obtained for fat-soluble dyes and organic pigments (0.1–1.5 g/kg) as well as disperse fillers and inorganic pigments (5–12 g/kg). Types of dyes and fillers and their optimal concentrations for fat-soluble dyes, organic pigments and disperse fillers were determined. Parameters of the process of ultrasonic welding of dyed and filled plastics were defined. It was established that welded products with the recommended optimal concentration and types of dyes and fillers showed the best weldability, increased strength and performance, and could be used longer under various climatic conditions.

Published: January 2020

Structural synthesis of closed kinematic chains to create various mechanisms is the first and most difficult stage of creative design of complex machines due to the large variance of possible structural solutions. In this paper, the authors examine the problem of structural synthesis of a family of eight-link kinematic chains with multiple joints of various types and the most complex three-joint link in order to create multi-loop multiple-joint mechanisms with one degree of freedom. To solve this problem, a synthesis technique is proposed based on the search for all integer solutions of a generalized structural mathematical model of plane linkage mechanisms and the identification of all structurally nonisomorphic kinematic chains using a two-column P-matrix. As the result of the structural synthesis, a family of eight-link multiple joint kinematic chains is obtained, which contains seven new kinematic structures. Examples of creating 1-DOF mechanisms with multiple joints based on the obtained new structures are presented. They confirm the effectiveness of using the structural synthesis procedure and analysis of complex mechanisms with multiple joints in various areas of modern engineering (precise guiding mechanisms, automatic lines, technological machines, robots, manipulators, etc.).

Introdução: Sob a perspetiva dos custos assumidos pelo cuidador informal e pessoa cuidada, este estudo pretende quantificar e valorar a utilização de serviços de saúde e sociais, assim como o tempo dedicado aos cuidados prestados em situações de demência.Material e Métodos: Recolheram-se informações sociodemográficas e de utilização de serviços de 123 díades de cuidados. Os custos foram estimados considerando: Setor Saúde (serviços de saúde), Doente/Família (tempo de cuidados) e Outros (serviços sociais, cuidados continuados, outros privados). A avaliação dos custos do Setor Saúde e Outros Setores considerou a pessoa pagadora; para o Setor Doente/Família aplicou-se o método do bem-substituto. Calculou-se o custo mensal para os utilizadores e o valor para 100 díades.Resultados: O custo total dos cuidados informais foi de €61 982,2/mês por 100 díades. O valor do Setor Doente/Família (€44 030,0/mês) contribui com 71,0% do custo total; os Outros Setores com 20,8% (€12 887,4/mês), seguido do Setor da Saúde com 8,2% (€5064,8/mês).Discussão: O valor obtido para cada díade (€619,8/mês) representa 77,5% do seu rendimento mensal (mediana = €800,0; amplitude interquartil = 679,0), o que pode condicionar a continuidade dos cuidados em casa. Em face aos montantes apresentados para estaamostra, estima-se a presença de isenção de taxas moderadoras no Setor Saúde e/ou benefícios na comparticipação das respostas sociais e, como tal, uma estimativa em baixa dos gastos apresentados.Conclusão: Apesar da complexidade na estimação dos custos associados aos cuidados informais na demência, este artigo ilustra o peso significativo que estes podem alcançar para as famílias.
O Poder Psicoativo dos Alimentos: Análise de um Caso de Intoxicação com Noz-Moscada

A ingestão de noz-moscada em doses elevadas provoca consequências médicas e psiquiátricas potencialmente graves e incapacitantes. Nenhum componente isolado da noz-moscada foi identificado como responsável por todos os sintomas observados durante a intoxicação, contudo, acredita-se que a miristicina, que é um dos componentes dos óleos essenciais desta especiaria, é o responsável pela maioria dos efeitos psicoativos, embora o mecanismo exato não seja conhecido. Outros constituintes, como a elemicina, também podem estar envolvidos. Os sintomas da intoxicação iniciam-se três a seis horas após a sua ingestão, remitindo nas primeiras 24 a 48 horas, e normalmente não deixam sequelas. Neste trabalho apresentamos o caso de um homem que após o consumo de 18 a 28 g de noz-moscada desenvolveu um episódio psicótico grave, com discurso desorganizado, agitação psicomotora e ideação delirante mística/grandiosa. A sintomatologia remitiu rapidamente e após um ano de estabilidade clínica sem terapêutica, teve alta da consulta da especialidade.
