Imprudências poéticas
Authors: Oliveira Maria Rosa Duarte de
Published: January 2019

O artigo objetiva refletir sobre as formas breves no âmbito literário, focalizando a temática de um duplo ponto de vista: de um lado, refletir sobre o conceito de brevidade, que aqui será entendido no sentido poundiano e ideogrâmico de condensação; de outro, analisar o impacto destas formas breves num romance contemporâneo – Homens imprudentemente poéticos (2016), de Valter Hugo Mãe, gênero que, ao contrário da poesia, caracteriza-se mais pela expansão do que pela contenção. A premissa que conduz a nossa interpretação crítica é a de que há, na fundação deste romance, um entrespaço liminar no qual oriente e ocidente perdem as fronteiras que os separam para constituírem um novo campo tensional e dialógico entre forças diferentes, mas complementares. Cada capítulo possui uma dupla face: de um lado, é um instantâneo condensado entre palavra, visualidade e sentido, inspirado nas formas breves da literatura e da arte caligráfica japonesa como o haicai e o sumiê; de outro, expande-se em conexões com aqueles que ora o antecedem, ora o sucedem, sem que a causalidade se estabeleça, a fim de que uma trama se constitua. Entre poesia e prosa, a imprudência poética deste romance se perfaz.
A precafização do trabalho docente: análise crítica das alterações no ambiente de trabalho produzidas no ensino superior a distância
Authors: De oliveira Lourival José , Souza de Almeida Tamires
Published: January 2019

A presente pesquisa aborda, utilizando-se do método dedutivo e como meio de pesquisa o levantamento bibliográfico, a precarização do trabalho docente no ensino superior a distância no Brasil, acarretada, principalmente, pelas mudanças no seu ambiente de trabalho produzidas em parte peloemprego de novas tecnologias. A não regulamentação dessa forma específica do trabalho justifica o seu estudo, sendo que o emprego das novas tecnologias inseridas nesse meio laboral trouxeram consequências danosas, podendo ser afirmado que ocorreu grandes mudanças na maneira da prestação do trabalho. Conclui-seque o trabalho doprofessor noensino superior a distância encontra-se em processo de desumanização, carecendo de uma regulamentação específica que seja suficiente para preservar a dignidade humana. Enquanto isso não acontece, as decisões judiciais sobre a matéria deverão buscar, nosprincípios norteadores do Direito do Trabalho e do Direito Ambiental do Trabalho, os parâmetros de proteção ao trabalho docente inserido nesse processo.Palavras-chave: Ambiente de trabalho. Ensino a distância. Precarização. Trabalho docente.

A “terceirização” na administração pública: o uso do direito e da linguagem jurídica no contexto do RE nº 760.931/DF
Authors: Marchioni Alessandra , Borba Daniel Miranda
Published: January 2019

Esse artigo tem como objetivo apontar alguns dos principais elementos da teoria e da prática da “terceirização” das condições laborais do trabalhador, compreendida sob a forma de contratos de gestão ou termos de parcerias para a execução de atividades-meio, depois atividades-fim, entre a Administração Pública e a pessoa jurídica de direito privado, desde um contexto histórico normativo de resultados, tanto do ponto de vista da extensão, quanto da ampliação de seus conteúdos. Além disso, seguindo a perspectiva bourdiana, propõe-se a realizar uma abordagem sobre o Estado e o direito, sua função e seu funcionamento, a partir do uso da linguagem jurídica, especialmente identificada na decisão do RE 760.931/DF. Nessa pesquisa será utilizado o método de abordagem hipotético dedutivo, em que se busca testar a hipótese da “satisfação da eficiência e modernidade” mediante os contratos de terceirização, a partir da demonstração das consequências jurídico-normativas e sociais.
Quão humano é o procedimento de mediação/conciliação?
Authors: Amaro Fernandes Igor Benevides , Cabral Coutinho Carlos Marden
Published: January 2019

O presente trabalho tem por objetivo investigar em que medida os programas de computador podem auxiliar (ou mesmo assumir pra si) o desempenho da função de mediação/conciliação. Para tanto, pretende-se inicialmente apresentar como a Internacional Business Machines (IBM) revolucionou o mercado das profissões de alta complexidade, desenvolvendo o Watson, programa destinado a realizar diagnósticos médicos. Na sequência, será discutido como o Watson (seguido por outros programas congêneres) passou a ter uma versão jurídica e tem progressivamente assumido funções que antes eram consideradas típicas de advogados. Como desenvolvimento, far-se-á uma reflexão a respeito das habilidades específicas exigidas nas atividades de mediação e conciliação, para tentar inferir até que ponto elas podem ser terceirizadas para não humanos. Por fim, buscar-se-á uma conclusão que estime até que ponto os programas de computador têm reais chances de assumir exclusivamente as atividades de mediação e conciliação, dispensando qualquer colaboração humana.
O comando político-jurídico da constituição: ideologia e vinculação hermenêutica
Authors: Ciola de Castro Paulo Roberto
Published: January 2019

Discorre-se acerca da propositiva visão de João Luiz Martins Esteves, esboçada em sua obra intitulada “O Comando Político-Jurídico da Constituição: Ideologia e Vinculação Hermenêutica”, especificamente no Capítulo 5, titulado “Uma Teoria Jurídica Adequada à Constituição Brasileira”. Expõe-se a visão de referido jurista, no sentido de que se deve buscar a maneira adequada de se interpretar e aplicar as disposições da Constituição Federal Brasileira de 1.988. Poder-se-á notar críticas a teorias comumente adotadas, referentes à vulgarizada técnica de ponderação entre princípios, que fatalmente culmina em desrespeitos aos comandos constitucionais. Além disso, apreende-se a proposta de utilização da metodologia hermenêutica cunhada por Luigi Ferrajoli, acrescida de adaptações à realidade do ordenamento jurídico brasileiro.

Acesso à justiça pela atuação profilática do tabelião: a mediação extrajudicial como meio alternativo de solução de conflitos
Authors: Zenkner Anna Christina , Silva Juvêncio Borges
Published: January 2019

O artigo discute o direito fundamental do acesso à justiça e a necessária ressignificação do seu conteúdo, diante de uma crise institucional vivenciada pelo Poder Judiciário no Brasil. O colapso do sistema jurisdicional, que descredita o Judiciário e o deslegitima enquanto Poder, faz nascer a imperiosa necessidade de se discutir mecanismos alternativos para a solução de controvérsias, que mitiguem o excesso de judicialização. Assim, o conceito de acesso de justiça deve ser interpretado à luz da realidade jurídica nacional, com soluções que transcendem o Poder Judiciário, tais como a mediação e a conciliação. Nesse sentido, o desenvolvimento da mediação extrajudicial, além de possível, é desejável e permitirá, em boa medida, uma ruptura com a “cultura da sentença” e o descongestionamento dos tribunais. A pesquisa se orienta pelo método analítico-dedutivo, com fulcro em livros, artigos científicos e jurisprudências para, ao final, demonstrar que a atuação preventiva e mediadora do notariado pode construir muitas soluções dialogais e impedir que muitos processos judiciais se iniciem. É, pois, a profilaxia a serviço da doença crônica denominada inefetividade e morosidade judicial.

A trans-memória das imagens, sentir o tempo e inquietar-se: o caso Sonderkommando
Authors: Susigan Cristina
Published: January 2019

Se a memória se constituiu, desde o seu início, como um terreno privilegiado da história, ela não é menos importante para outras áreas do pensamento, como as artes. Se a história a utilizou e a integrou como um dos seus conceitos fundamentais, transformando-a num conceito operatório do pensamento, as artes permitem descrever a “vida póstuma” das formas da cultura e das manifestações artísticas. Relembro, Walter Benjamin e o seu conceito de “Rememoração”, como o próprio conceito de Aby Warburg, nomeadamente o de “Imagem Sobrevivente”, e aqui aparece uma outra componente, que se desdobra a partir daquela: a relação da imagem com a própria história e também a da memória que sobrevive nas imagens. Este artigo tem o intuito de analisar as quatro fotografias que foram realizadas pelos prisioneiros do campo de Auschwitz-Birkenau em risco de vida, os Sonderkommandos, mostrando que as imagens são a hipótese de reconstrução do testemunho.
Filmes, compreensão e empatia histórica: contribuições de um estudo empírico
Authors: Souza Éder Cristiano de
Published: January 2019

O uso de filmes em aulas de História é temática amplamente debatida e difundida nos estudos sobre Ensino de História. Contudo, é raro encontrar estudos derivados de investigações empíricas para observar os limites e potencialidades da aprendizagem histórica mobilizada em tais atividades. Essa é a proposta do presente artigo, que apresenta parte dos resultados de uma pesquisa sobre a aprendizagem histórica de jovens a partir de filmes em aulas de História, direcionados a partir do conceito de “cognição histórica situada”. Propõem-se, então, caminhos para se pensar os filmes no ensino, principalmente a partir dos conceitos de “compreensão histórica” e “empatia histórica”, que permitem superar uma visão segundo a qual esta aprendizagem seria resultado exclusivo dos estímulos provocados pela linguagem fílmica.
O princípio da educação especial em Naviraí/MS: professoras que contam a história
Authors: Santos Novais Rute , Gonçalves Josiane Peres , Ferreira Bezerra Giovani
Published: January 2019

O presente estudo refere-se aos trabalhos iniciais da Educação Especial em Naviraí e visa compreender como era oferecida a educação formal às crianças com deficiência, desde o surgimento do município, em 1963, quando não havia escolas especializadas em atendê-las, até 1986, ano em que surge o Centro de Educação Especial Naviraiense (CEDEN), que atualmente funciona juntamente com a Associação de Pais e Amigos dos Excepcionais (APAE). Apresenta um breve histórico de Naviraí, da Educação Especial no Brasil e a legislação que rege a Educação Especial no país. A pesquisa de campo, de natureza qualitativa, foi realizada por meio da gravação de entrevista com duas professoras que trabalharam com salas especiais no período investigado e também contribuíram com a implantação da APAE no município. Os resultados indicam que, embora as primeiras salas de aula tenham surgido em 1958, foi somente em 1976 que houve a implantação de uma sala, anexa à escola municipal Marechal Rondon, voltada ao atendimento de crianças com deficiência, sendo todas matriculadas na mesma turma, apesar de suas especificidades. A formação das duas professoras, para trabalhar com esses alunos, consistia em um curso realizado em Cuiabá, alguns meses antes da abertura da classe especial. Evidencia-se que Naviraí acompanhou o sistema educacional vigente no país, visto que as salas especiais foram implantadas no mesmo período em que começou a surgir, no Brasil, um maior investimento relacionado à educação especial.
O espetáculo por trás do canteiro de obras: estratégias discursivas dos projetos de revitalização na cidade olímpica
Authors: Silva Clara Luisa Oliveira , Saraiva Luiz Alex Silva
Published: January 2019

O objetivo deste artigo é analisar os discursos relacionados aos projetos de requalificação das cidades, buscando identificar as estratégias que legitimam (ou que pretendem legitimar) o processo de (re)produção do espaço urbano. Adotando uma abordagem qualitativa, foram problematizadas as obras de revitalização da região portuária da cidade do Rio de Janeiro, transformações estas que se fazem concretas nos ditos projetos de recuperação ou revitalização das cidades. Por meio da análise do discurso, buscou-se interpretar as construções discursivas que compõem parte do material secundário na forma de textos ou vídeos coletados nos sites oficiais do projeto. Os principais resultados sugerem a discussão da interdependência entre as categorias tempo e espaço, bem como as possibilidades para a “recuperação” e “comercialização” de memórias e identidades urbanas. Ademais, o estudo permite reflexões sobre o sentido de espaço urbano democrático e sobre a participação do Estado na (re)produção do espaço urbano.
Modelling and Simulation of Laser Welded Joints of Reinforced PP and PC Plastics
Authors: Votrubec Vlastimil
Published: January 2019

Welding of composites decreases their material strength. Proper evaluation of FEM simulations is necessary for correct design and safety factor determination. Neat and reinforced PP and PC specimens were measured on a testing machine to obtain their material properties. Experimental tensile curves were used as inputs in FEM simulations. 15 combinations of specimen were welded on laser work machine and afterwards the welded joint strength was measured on the testing machine. The results of shear tests and FEM simulations are compared in this paper. Also the influence of fiber presence in composites on welded joint strength is discussed. At the end suggestions for safe machinery design of laser welded reinforced composites are given.
THE EFFECT OF NANOCRYSTALLINE LAYERS ON THE WEAR RESISTANCE OF GREY CAST IRON DURING FRICTION IN AN OIL-ABRASIVE MEDIUM
Authors: HUREY Ihor , HUREY Tetyana , GUREY Volodyr
Published: January 2019

Friction hardening is one of the surface hardening methods with the use of highly concentrated energy sources. In the “tool-treated surface” contact area, the surface layer of a metal is heated at a very high rate to phase transition temperatures, and then it is cooled at a high rate, which results in the formation of hardened nanocrystalline layers. The studies carried out have shown that a hardened nanocrystalline layer is formed in the surface layer in the course of friction hardening of cast-iron (EN-GJL-200) components. The layer thickness is 90–120 μm, and the microhardness is 7–8 GPa. Grain size of the hardened surface layer was equal to 20–40 nm near the treated surface. It is shown that the hardened layer significantly increases the serviceability of the pair “grey cast iron-grey cast iron” during sliding friction in the lubricated-abrasive medium. When increasing the unit load from 2 to 6 MPa, the wear rate of the hardened pair decreased by 2.6–4.2 times in comparison with an unhardened pair. Only one component of the friction pair was hardened.

This article presents some selected results of the research on the slide porous bearings, sintered from the
iron powder Höganas NC.100.24, with 2.5% of copper addition by weight, impregnated with selected ionic
liquids, through comprehensive and detailed research works [L. 1–6]. The research was carried out within the
framework of PBR/15-249/2007/WAT-OR00002904 Research Project financed by the Ministry of Science
and Higher Education, during 2007–2011 [L. 7]. Several times higher load capacities and durabilities were
obtained in comparison with standard ø25/ø35×20 mm sleeves lubricated with previously used oils, including
perfluoropolyether oils. To date, there were no bearings sintered from the iron powder and impregnated with
ionic liquids. The durability and load capacity of such bearings are higher, and that is why it was decided to
submit a proper patent claim to the Polish Patent Office [L. 8].

Published: January 2019

Cloud computing is maturing and becoming ubiquitous in people’s daily lives. As a result, cloud environments are providing moreand more services with better quality of service. Cloud customers, however, have suff ered from the vendor lock-in problem, in such a way that those who wish to migrate to another cloud provider require partial or total reimplementation of applications and virtual infrastructure. Moreover, the problem of heterogeneity among distinct cloud environments makes it diffi cult for the portability of resources between them. Therefore, this work focuses on the development of an ontology to handle multi-cloud heterogeneity, and thus, bring interoperability in the form of a service to perform the portability of virtual machines between diff erent providers.

MobSink: a Visual Mobile Wireless Sensor Networks Positioning Simulator
Authors: Peixoto João Paulo Just , Costa Daniel G.
Published: January 2019

The planning and deployment of a WSN (Wireless Sensor Network) in a Smart City can be a very challenging work. People involved in such implementation must be aware of how sensors and sinks may behave in the target environment. To aid the development of new WSNs, simulation tools are often used to predict how nodes will interact before spending time and money in a real deployment. Also, simulator can help students better understand WSNs. In this paper, we present MobSink, a simulator for WSNs with multiple mobile sinks. MobSink also allows to perform simulations in a Smart City scenario, with streets and movements constraints. It also shows how to configure MobSink for a generic scenario and describes how it works internally.

Published: January 2019

The liquidus surface of the system (LiF)2-Li2SO4-Li2CO3 was studied by the calculated and differential thermal method of physicochemical analysis. An analysis of the systems of lower dimensionality of the facets of the investigated object showed that the most informative, for the experimental study, is the sections located in the crystallization field of lithium fluoride. A study of the DTA of a number of compositions located at the initially chosen polythermal section in the lithium fluoride crystallization field, the ratios of lithium sulfate and carbonate in the eutectic are determined. The composition of the triple eutectic was revealed by studying a non-invariant cut from the vertex of the triangle (LiF), through a point showing a constant ratio of sulfate and lithium carbonate in the eutectic, to the fusion of the thermal effects of the primary and tertiary crystallizations. The complexity of the study was that lithium carbonate is the most fusible component in the system, and according to the literature, after the melting of lithium carbonate, decomposition begins, which greatly complicates the interpretation of research results. In order to avoid the decomposition of lithium carbonate, each experimentally studied composition was heated to the melting temperature of lithium carbonate and kept in isothermal mode, at a temperature below its melting. Thus, the theoretical melting calculations and the region of location of the non-invariant composition have been extrapolated, allowing to limit the number of experimentally studied samples, and the subsequent experimental investigation of DTA of two polythermal sections revealed a eutectic composition crystallizing at 476 ° C and containing LiF-20 eq.%, Li2SO4 - 51 eq.%, Li2CO3 – 29 eq.%. The discrepancies between theoretical calculations and experimental studies are 8.3% in temperature and 5.05% in composition.
MODIFICATION OF LOW-MOLECULAR COPOLYMER FROM BY-PRODUCTS OF BUTADIENE RUBBER BY SECONDARY EXPANDED POLYSTYRENE

Published: January 2019

From the literature data it is known that in industrial and civil construction it is widely used expanded polystyrene as a heat-insulating material, which is in demand on the market. In order to solve a number of ecological problems, in this work attempts have been made to chemically combine two types of polymer waste (by-products of petrochemistry in the presence of expanded polystyrene) to obtain impregnating compounds at the molecular level by carrying out their joint destruction and applying wood products for protective treatment. Obtained wood-polymer composites from natural wood (birch) and wood fiber boards (DVP) were investigated for resistance to water and moisture. Indicators of tests of wood for water absorption and swelling in the radial and tangential directions indicate that the samples under investigation have increased hydrophobic properties. Modified fiberboards acquire, in addition to increased hydrophobic properties and higher strength parameters. This is due to the cross-linking of oligomer molecules in wood structures with the formation of a wood-polymer framework and the formation of hydrogen and ether bonds between the wood components and the oxidized modified oligomer. The formation of such bonds makes it possible to reduce such a shortage of impregnating compositions as washability from products during their operation. Reducing the uncertainty of the oligomeric modifier reduces its hydrophilic properties. Integrated use of waste and by-products allows to purposefully dispose of them and use them for protective processing of materials, which include wood components, which contributes to the increase of the service life of products.

Published: January 2019

The objective of this study is to elaborate the analytical theory of ion exchange in the field of solving the boundary value problems of non steady state mass transfer in solids with a canonical form taking into account a change in the concentration of the solution and the character of movement of the phases in a flow apparatus. The mathematical description of the process of ion-exchange solution purification on ionite particles of cylindrical shape in a batch flow apparatus was developed. At the developing mathematical description the following assumptions were used: the ionite is monodisperse, uniform initial distribution of substances in the ionite, the ion exchange equilibrium is described by Henry equation, the rate of the process is limited by both internal and external diffusion, the flow pattern of the liquid phase in the apparatus is described by the perfect mixing model, the solution with the constant volumetric flow rate and the constant concentration of the substance  is supplied to the apparatus, kinetic and hydrodynamic process parameters are constants. Mathematical description includes the following equations: the diffusion equation of ionite, isotherm equation ion exchange, the equation for average concentration of the substance in the ionite, the material balance equation for a perfect mixing flow apparatus, initial and boundary conditions. To solve boundary value problem, we use the integral Laplace transformations. The obtained equation allows to analyze the effect of the volumetric flow rate of the solution supplied to a flow apparatus, the ratio of the volumes of solid and liquid phases in the apparatus, the diameter of the particle, and other parameters of the process on the concentration distribution of a substance along the internal coordinate of the solid. The developed mathematical model is used to study the desorption of copper ions from the modified polycaproamide fiber with sulfuric acid solution.

Endometriosis is an estrogen-dependent chronic inflammatory condition that affects women in their reproductive period and is associated with pelvic pain and infertility. Oxidative stress (OS) occurs when reactive oxygen stress (ROS) and anti-oxidants are in imbalance. OS is a potential factor involved in the pathophysiology of endometriosis. Iron-induced ROS may trigger a chain of events resulting in the development and progression of endometriosis. Endogenous ROS are correlated with increased cellular proliferation and ERK1/2 activation in human endometriotic cells. An oxidative environment leads to stimulation of the ERK and PI3K/AKT/mTOR signaling pathways that facilitate endometriotic lesion progression through adhesion, angiogenesis, and proliferation. OS is also known to be involved in epigenetic mechanisms in endometriosis. We summarize the recent knowledge in our understanding of the role of oxidative stress in the pathogenesis of endometriosis.

Hot flush (hot flush or facial flush) is the most frequent symptom experienced by women of peri-menopausal age. It may appear on women or even men after surgery or chemotherapy. Hot flush is one of the biggest reason for women to undergo hormone replacement therapy (HRT). It also crucially affects various aspects of life quality such as occupation, social life, daily routine and health awareness. The most effective and fundamental remedy for hot flush is HRT. However, a few women is not responsive to HRT and investigation to elucidate other causes of hot flush is warranted, especially in elderly. The contraindications such as breast cancer mandates other modality of treatment. Variety of treatment for hot flush other than HRT will be discussed herein.

Although Campylobacter is the main cause for bacterial acute gastroenteritis (AGE), there has been no notable clinical research into it, especially for Korean children. In this study, we share our experience of clinical, laboratory and image findings with Campylobacter AGE. Methods Between May 2013 and June 2016, children diagnosed as having Campylobacter AGE were retrospectively enrolled in our study. Campylobacter AGE was considered diagnosed when a patient had symptoms of bacterial AGE and a positive Campylobacter result in stool using multiplex PCR. Results Among 539 patients with suspected bacterial AGE, 31 (5.8%) patients had a positive result for Campylobacter. The average age of the 31 patients was 10.2 ± 5.0 years with a range between 1.1 and 16.9 years. Eighteen (58%) of the total patients were hospitalized between June and August. Diarrhea (93.5%), abdominal pain (83%) and fever (83%) were common symptoms. For 20 patients (65%), diarrhea lasted for less than three days, and fever lasted for 2.1 days on average. Among the 20 patients subjected to imaging studies, 12 patients (60%) showed bowel wall thickening on the right side of colon. In blood tests of 30 patients, 22 (73%) and 29 (97%) patients exhibited leukocytosis and elevated C-reactive protein, respectively. During treatment for Campylobacter AGE, prediagnostic empirical antibiotics were used for 6 (19%) patients. All patients recovered without complications. Conclusions Among the children with suspected bacterial AGE, 5.8% had a positive result on Campylobacter in stool using multiplex PCR. Therefore, we observe that Campylobacter AGE should be considered in school-age children who have diarrhea, fever, and abdominal pain.

Our school introduced a new curriculum based on faculty-directed, intensive, small-group teaching of clinical skills in the third-year medical students. To examine its effects, we compared the mean scores on an OSCE between the third- and fourth-year medical students. Methods Third- and fourth-year students did rotations at the same five OSCE stations. They then completed a brief self-reporting questionnaire survey to examine the degree of satisfaction with new curriculum in the third-year students and clinical practice in the fourth-year students, as well as their perception of confidence and preparedness. We analyzed the OSCE data obtained from 158 students, 133 of whom also completed the questionnaire. Results Mean OSCE scores on the breast examination and wet smear stations were significantly higher in the third-year group (P < 0.001). But mean OSCE scores of motor-sensory examination and lumbar puncture were significantly higher in the fourth-year group (P < 0.05). The mean OSCE scores had no significant correlation with satisfaction. In addition, the self-ratings of confidence had a high degree of correlation with satisfaction with new curriculum (r = 0.673) and clinical practice (r = 0.692). Furthermore, there was a moderate degree of correlation between satisfaction and preparedness in both groups (r = 0.403 and 0.449). Conclusions There is no significant difference in the effect on the degree of clinical performance and confidence between an intensive-small group teaching and a 1-year clinical practice. If combined, intensive small group teaching and clinical practice would be useful to improve the degree of ability and confidence in medical students.
A Case of Fitz-Hugh-Curtis syndrome in a male patient

Published: January 2019

Fitz-Hugh-Curtis syndrome has been described as perihepatitis associated with pelvic inflammatory disease (PID). It is classically seen in premenopausal young women who have right upper quadrant pain, usually but not always accompanied by symptoms of PID, and is frequently confused with biliary tract disease. However, the syndrome has rarely been reported in males. The predominant symptom is right upper quadrant pain, but PID may not be present in male patients. Here, we report a case of Fitz-Hugh-Curtis syndrome in a young male patient, which was diagnosed by serological tests and computed tomography. Fitz-Hugh-Curtis syndrome should be considered as a possible cause of pain in the right upper quadrant in male patients, although such a case is very rare.
A double-knotted pulmonary artery catheter with large loop in the right internal jugular vein: A case report

Knotting of a pulmonary artery catheter (PAC) is a rare, but well-known complication of pulmonary artery (PA) catheterization. We report a case of a double-knotted PAC with a large loop in a patient with hepatocellular carcinoma (HCC) undergoing liver transplantation, which has been rarely reported in the literature. A PAC was advanced under pressure wave form guidance. PAC insertion was repeatedly attempted and the PAC was inserted 80 cm deep even though PAC should be normally inserted 45 to 55 cm deep. However, since no wave change was observed, we began deflating and pulling the balloon. At the 30-cm mark, the PAC could no longer be pulled. Fluoroscopy confirmed knotting of the PAC after surgery (The loop-formed PAC was shown in right internal jugular vein); thus, it was removed. For safe PA catheterization, deep insertion or repeated attempts should be avoided when the catheter cannot be easily inserted into the pulmonary artery. If possible, the insertion of PACs can be performed more safely by monitoring the movement of the catheter under fluoroscopy or transesophageal echocardiography.
The complete chloroplast genome of Fagus crenata (subgenus Fagus) and comparison with F. engleriana (subgenus Engleriana)

Published: January 2019

This study reports the whole chloroplast genome of Fagus crenata (subgenus Fagus), a foundation tree species of Japanese temperate forests. The genome was a total of 158,247 bp in length containing 111 genes. Comparison with the only other published Fagus chloroplast genome, F. engeleriana (subgenus Engleriana) shows that the genomes are relatively conserved with no inversions or rearrangements observed between them and differing by 311 single nucleotide polymorphisms. The six most variable regions between the two genomes were the psbK-psbI, trnG-psbfM, trnV, rpl32, ndhD-psaC and ndhI-ndh regions. These highly variable chloroplast regions and the identification of 42 variable chloroplast SSRs found to be shared between the two species will provide useful genetic resources for studies of the inter- and intra-specific genetic structure and diversity of this important northern hemisphere tree genus.
An automatic fascicle tracking algorithm quantifying gastrocnemius architecture during maximal effort contractions

Published: January 2019

Background. Ultrasound has become the gold-standard for making dynamic measurements of muscle structure during functional movements in biomechanical studies. Manual measurements of fascicle length and pennation angle are time intensive which limits the clinical utility of this approach while also limiting sample sizes. The purpose of this study was to develop a novel tracking paradigm to quantify individual fascicle length and pennation measurements during maximal voluntary contractions and demonstrate is repeatability between days and reproducibility between different examiners.

Methods. Five healthy young adults performed maximal isokinetic contractions at 0, 30, 120, 210, and 500 degrees about their ankle on an isokinetic dynamometer while their gastrocnemius muscle was observed using ultrasound. Individual muscle fascicles were identified in the first frame, and tracked using the automatic fascicle tracking algorithm and a manual approach by three observers on three separate days. Repeatability within examiners across days and reproducibility across examiners and days was evaluated using intraclass correlation coefficients. Agreement between manual and automatic tracking was evaluated using the coefficient of multiple correlations. Supervised automatic tracking was performed on all videos by one examiner to evaluate the fidelity of automatic tracking in practice.

Results. We found both manual and automatic measurements of fascicle length and pennation angle to be strongly repeatable within examiners and strongly reproducible across examiners and days (ICCs>0.76). There was greater agreement between manual and automatic measurements of fascicle length than pennation angle, however the mean CMC value for both was still found to be strong in both cases (CMC>0.8). Supervision of automatic tracking greatly showed very strong agreement between manual and automatic measurements of fascicle length and pennation angle (CMC>0.94).

Conclusions. We have developed a novel automatic fascicle tracking algorithm that quantifies fascicle length and pennation angle of individual muscle fascicles during dynamic contractions across a range of velocities. We demonstrated that this fascicle tracking algorithm is repeatable and reproducible across different examiners and different days and showed strong agreement with manual measurements, especially when tracking is supervised by the user so that tracking can be reinitialized if poor tracking fidelity is observed.
