Authors: Mladina Nada , Hadzic Devleta , Konjic Elvira , Mladina Zarko
Published: January 2020

Introduction: Urine sample for biochemical analysis must fulfill certain criterions. The sample collection must be done by following established standards so that the results of analysis are reliable. In children of various age, especially during serious disease, adequate consideration must be devoted to this procedure.Aims: To evaluate contamination rate of the urine sample according to the methods of obtaining samples and collecting specimens in seriously sick children of various age during their intensive treatment.Methods: Urine culture findings in children treated in Intensive Care Unit (ICU) of Children’s Hospital in Tuzla in period from January 2007 to the end of December 2007 were included in retrospective analysis according to the method of collecting (bag collection, urethral catheterization, clean catch). In all of the three groups the percentage of positive findings and percentage of contaminated specimens as well as sex related distribution was analyzed. The urine sample was obtained from urethral catheter only in patients with indication for urethral catheterization. Kruskal-Wallis test and regression model were used in statistical analysis. Results: A total of 662 children were treated in ICU during the observed period. The urine sample for routine biochemical tests was obtained from all patients. In 107 patients (16.2 %) urine culture examination was indicated. In 48 (44.9%) patients urine sample was obtained by bag collection, in 41 (38.3%) by clean catch, and 18 (16.8%) by urethral catheterization. In 7 patients or 6.5% urine was contaminated. The majority of contaminated specimens were collected by bag (12.5%). In 20 (18.7%) patients urine culture was positive with significant number of etiologic agents and 80 (74.8%) specimens were negative. Difference in results in three monitored groups was statistically significant which was confirmed by Kruskal-Wallis test and stepwise regression model.Conclusion: Obtaining urine sample by bag collection brings the highest risk for contamination.

Objectives: Anaerobic bacteria may cause numerous infections in different locations through human body. Those infections can be life-threatening with significant mortality. Wounds represent a suitable habitat for colonization of anaerobic bacteria. Their proliferation contributes to moist and warm environment, hypoxic and necrotic tissue.Methods:A retrospective study was conducted at the Clinical Centre University of Sarajevo from 2015-2017. The study involved wound swab samples, sampled from hospitalized patients. The anaerobic bacteria were isolated using standard procedures.Results: During the period from 01.01.2015. to 31.12.2017, 8386 samples were analyzed on anaerobic bacteria and 872 (10.4%) of specimen were positive. In 2015, 332 (15%) specimens were positive, while during 2016 and 2017, 244 (7,8%) and 296 (9.9%) respectively. Bacteroides spp. was the most common isolate during three year period: 2015-227 (55.5%); 2016-139 (48%); 2017-161 (42,5%). It was followed by Peptococcus spp.: 2015-70 (17.1%); 2016-40 (13.9%); 2017-66 (17.4%), Clostridium spp.: 2015 – 32 (7.8%); 2016-21 (7.3%); 2017- 35 (9.2%), Fusobacterium spp.: 2015 – 49 (11.9%); 2016-32 (11.1%); 2017- 45 (11.9%).VITEK 2 Compact has identified to the level of species 48 isolates which were in pure culture.The largest number of anaerobic bacteria were isolated from the samples received from the Abdominal surgery. The overview of antimicrobial sensitivity showed highest sensitivity to metronidazole (99,9%) and carbapenems (99,9%), respectively.Conclusions The most commonly isolated anaerobic bacteria was Bacteroides spp.Highest number of positive isolates was from abdominal surgery since intra-abdominal infections reflect the microflora of the resected organ.

Introduction: Current international guidelines recommend H1 and H2- antihistamines as a second or third- line drugs for the management of anaphylaxis. Aim: To present positive cardiovascular and dermatological effects of Chloropyramine and Ranitidine as the combination of H1 and H2- antihistamines in additive therapy of anaphylaxis. Patients and methods: In a retrospective study two groups of 146 patients who met the NIAID/FAAN criteria for the diagnosis of anaphylaxis were compared. Experimental group consisted of 62 patients who received combination of Chloropyramine H1- antihistamines and Ranitidine H2- antihistamines. Control group consisted of 84 patients who received only Chloropyramine H1- antihistamines. Results: A statistically significant differences of diastolic pressure and central pulse (p< 0.001), a higher values of diastolic pressure, and a lower values of central pulse in the experimental group of patients were recorded at the end of the prehospital treatment of anaphylaxis. The increase in the mean arterial blood pressure at the end of the treatment is higher in the experimental group compared to the initial values, with an average difference of 15 mmHg (%95 CI= 7,95-21,95). Total prehospital time and time recovery of the skin urticaria and itch was shorter in the experimental group for 18 minutes (95% CI= 11,95-25,95). Conclusion: Positive cardiovascular effects and a faster resolving of the skin symptoms justify the use of combination Chloropyramine and Ranitidine as an additive therapy of anaphylaxis that is not life- threatening, and of a rapid progression.

Published: January 2020

Introduction: Standing advances in neonatology increased survival of premature infants with the use of invasive procedures, which increases risk of infection and fungal sepsis. Risk factors for fungal sepsis are extensively studied. Candida is dominant, but there is increase in resistant C. non-albicans species. Mortality is high and requires timely suspicion of fungal sepsis, and adequate treatment to counteract the fatal outcome.Objectives: To analyze the clinical and laboratory characteristics of neonates, treated in the neonatal intensive care unit because of microbiologically proven fungal sepsis.Subjects and Methods:The restrospective observational study included 48 consecutive neonates, treated in Iintensive care unit of Pediatric Clinic Tuzla during three-year period (2016-2018), those with proven fungal sepsis, confirmed by positive blood culture. We analyzed perinatal history, clinical and laboratory presentation of disease, length of treatment and outcome. Statistical analysis applied standard methods, and the research was approved by the Ethics Committee of the institution.Results: Of the total treated 921 neonates, confirmed fungal sepsis were found in 48 infants (5.2%), evenly distributed by gender. Of perinatal risk factors, confirmed the prematurity and low birth weight, and significant were the presence of umbilical venous catheter, parenteral nutrition, longer antibiotic therapy and mechanical ventilation. Clinically, fungal sepsis manifested as late sepsis with respiratory higher requirements, lethargy, feeding difficulties and abdominal distension. The most common laboratory abnormalities were increased CRP, leukocytosis and thrombocytopenia. Outcome: 44 neonates (91.7%) survived, while 4 neonates (8.3%) died. Antifungal therapy lasted 20.6 ± 6 days, and intensive treatment 38.2 ± 23.2 days. All isolates were Candida species, in vitro without resistance. In 8 neonates (16.7%) recorded a slight toxic hepatitis.Conclusion: Recovery of neonates with fungal sepsis depend on timely clinical suspicion, adequate treatment and monitoring. Antifungal susceptibility is also important, which requires monitoring of local epidemiological data to improve treatment.

Authors: Rodrigues Monique de Lima Fonseca , Gomide da Silva Mello Marcia
Published: January 2020

Segundo a Organização Mundial de Saúde (OMS) na última década houve aumento na busca nos países desenvolvidos de terapias alternativas, incluindo a fitoterapia. A OMS estima que 80% da população mundial utilize fitoterapia. Por esses motivos a OMS preconiza a implantação de Programas de Fitoterapia eficazes como uma questão global de saúde. A partir do estudo quanti-qualitativo, com abordagem na ARS realizou-se entrevistas, construção e análise das redes pessoais de usuários de fitoterapia de uma Unidade Básica de Saúde no Rio de Janeiro. O serviço de fitoterapia é mais indicado na rede pessoal (84,62%) que por profissional de saúde, o serviço público representa 8,97% do total de referenciados da rede, contra 91,03% de indicações privadas. A rede dos usuários de fitoterapia é fragmentada. Os profissionais de saúde da UBS investigada têm baixa centralidade de intermediação na rede. Nossos achados sugerem que o acesso à informação sobre a prática da fitoterapia e a indicação para o serviço de fitoterapia é mais referenciado na rede pessoal do que por profissional de saúde. Essas informações são fundamentais para o planejamento, avaliação e eventual reformulação das estratégias de acesso ao programa de fitoterapia e podem ser aplicadas a demais programas de saúde.
Development of cardiovascular complications and their correlation with Lyme disease.
Authors: Grabos Aleksandra
Published: January 2020

Cardiovascular disease is at the forefront of global health issues and contributes to myocardial infarction, stroke,
and even death. Lyme disease (LD), spread by ticks of the genus Ixodes, is a contributing factor to the potential
development of abnormalities in the heart. The bacterial agents Mycoplasma pneumoniae, Chlamydia pneumoniae,
and Borrelia burgdorferi are known to cause a variety of infections and we speculate that infection with Borrelia
is a contributing factor to cardiac abnormalities, especially Lyme carditis (LC). Patients who demonstrate undiagnosed
cardiac abnormalities should be monitored for potential infection with Lyme disease and, consequently
LC. Lyme carditis affects up to 10% of patients that have been diagnosed with LD and additionally, it indiscriminately
manifests across a range of ages, from the pediatric populace to the elderly. Given the grave cardiac abnormalities
that can arise from LC and the propensity for misdiagnosis, it is critical that medical professionals be
aware of the cardiovascular signs and symptoms of Atrioventricular Heart Block (AHB). AHB can lead to third
degree heart block in patients and potentially lead to death if left not properly diagnosed and treated. Essential
treatments are readily available for Lyme carditis, which include a range of antibiotics and surgical procedures.
In this review, we highlight not only the true nature of Lyme disease, but more importantly, the positive correlation
between LD and a variety of undiagnosed heart complications.

This article includes an investigation of ethnic-racial relations in the curriculum of all undergraduate courses of a higher education institution located in the state of Mato Grosso do Sul. The state is the second in number of Amerindian inhabitants and of various ethnic groups and is located on the border with other countries constituting a multicultural state. Having regard to undergraduate courses role in preparing the future teacher to address the issues of ethnicity and diversity in schools, we aimedto analyze Law No. 10639/03 by degrees courses of all campus of an higher education institution of ,with a view to a discussion about how ethnic-racial relations are treated in the curriculum of undergraduate degrees with respect to teaching practices for equality. To do this, we approached the topic based on a bibliographic review about the education and ethnic-racial relations according to the Brazilian legislation. Supported by the methodology of qualitative research of exploratory type, we performed a detailed curricular documentary analysis of undergraduate courses. The results showed that in some undergraduate courses the discussion of ethnic-racial diversity is silenced, because this doesn't make part of the curriculum, in other courses we find a wide variety of approaches, different workloads that together also evidence the commitment or not of the courses with the issue analyzed. The analyses reinforce the need of formative processes of being able to combat discourses and narratives loaded with alot of stereotypes and prejudices.

FORMAÇÃO DOCENTE E A LÍNGUA BRASILEIRA DE SINAIS: PERSPECTIVAS ATUAIS
Authors: Silva Lais Agnes da , Rinaldi Renata Portela
Published: January 2020

This article aims to investigate what is indicated in the studies about the practice of the Brazilian Sign Language (Libras) in the initial teacher education courses. The research has a qualitative nature and it analyzes studies published from 2008 to 2018 in the national meetings of the National Association of Postgraduate and Research in Education, in the conferenceproceedingsof the Brazilian Congress of Special Education and in the CAPES Journal Portal. Data interpretation was conducted according to the content analysis criteria that consist of three stages: pre-reading, exploration and treatment, which corresponds to the categories comparison, aiming to obtain a unified concept. The results reveal that the number of scientific productions on the theme is still small and show a worrying scenario, since the way the subject is addressed in the initial education courses is superficial. Therefore, we conclude that the initial education and, specifically, the training of teachers to work with deaf students who use Libras in regular education -or even students with hearing impairment who do not use Libras as their mother tongue, but which also have significant differences -is still inadequate, fragile in many aspects and not enough investigated. The challenge to provide a bilingual quality education for the deaf in order to implement what is established in the legislation still remains, since the barrier communication between listeners and deaf people is yet to be broken.

Teste de desempenho de Algoritmo de Controle de Congestionamento TCP utilizando testbed FIBRE
Authors: Zanela Eduardo Henrique Rocha , Marcondes Cesar Augusto Cavalheiro
Published: January 2020

O controle de congestionamento do TCP é fundamental para manter um bom funcionamento e desempenho de uma rede de internet, pois controla a taxa de transmissão realizada pelos emissores, evitando ou reduzindo ocasiões de congestionamento. Apesar de diversos estudos realizarem testes entre diferentes TCP's, não existe um protocolo genérico ideal, mas sim protocolos que funcionam melhor em determinadas situações. Winstein e Balakrishan (2013) apresentaram no SIGCOMM1 um programa capaz de gerar algoritmos de controle de congestionamento para serem executados nos pontos finais da rede, o programa Remy. Os resultados apresentados no artigo, através de testes comparativos realizados pelo programa Network Simulation (NS2), demonstraram um funcionamento bastante superior aos protocolos atuais. Porém para a criação de novos algoritmos com diferentes cenários, o Remy requer um alto custo computacional, e ainda sim é necessário uma grande quantidade de dias para sua execução completa. Para a resolução desta problemática, criar uma versão suavizada do Remy permite minimizar o tempo de processamento e o custo computacional. Buscando facilitar o teste de desempenho e visando um teste em rede real, a utilização de uma testbed FIBRE se encaixa perfeitamente no cenário.

Seleção de Nó Raiz Ótimo para Sincronização Eficiente de Relógios em Redes de Sensores Sem Fio
Authors: Xavier Tiago C. de S. , Amorim Claudio L. , Delicato Flavia C.
Published: January 2020

Para reduzir o erro de sincronização de relógios em redes de sensores sem fio, trabalhos recentes buscaram otimizar a topologia da rede. Essas abordagens apresentaram desempenho limitado pois o nó raiz, o qual fornece o relógio global, pode continuar mal localizado mesmo após a otimização e em caso de falha, a recuperação é muito custosa. Este trabalho propõe duas abordagens para selecionar o nó raiz ótimo da rede: a primeira é baseada em grafos e a segunda é um algoritmo distribuído aplicado em um cenário de falha. Experimentos indicam que, comparadaá otimização de topologia, a seleção do raiz ótimo reduz cerca de seis vezes o erro de sincronização e que a abordagem distribuida é capaz de ser resiliente em cenários de falha do nó raiz.

Authors: Nogueira Tiago do Carmo , Campos Eudes de Souza , Ferreira Deller James
Published: January 2020

The scientific logical reasoning became an important skill in the students' cognitive development in algorithm teaching-learning processes, stimulating their reasoning and creativity. From this perspective, gamification has been adopted as a mediating tool in this process. Studies report that the inclusion of gamification in algorithm teaching-learning processes stimulates the students to develop new skills, making the knowledge more efficient. Therefore, this paper's purpose is to measure and understand the cognitive development and the experiences lived by students at the addition of gamification in algorithm teaching, evaluating the scientific logical knowledge acquired by them. Consequently, 44 computer higher education students were selected. They were divided into two groups: students that used the Gamification-Mediated Algorithm Teaching Method and those who participated in the traditional teaching method. To evaluate the cognitive development between these two groups, the Scientific Logical Reasoning Test was applied. The results showed that a significant number of students that used the Gamification-Mediated Algorithm Teaching Method reached the transitory intermediary and transitory scientific knowledge levels, with greater right answer rates. We also noticed that both genders gave more right answers using the gamification-mediated algorithm teaching method.

Published: January 2020

Aprender programação não é uma tarefa considerada simples por grande parte dos estudantes dos cursos técnicos e superiores de Informática. Essa dificuldade é refletida nos altos índices de evasão e reprovação nas disciplinas introdutórias de programação. Dentre os fatores que influenciam o baixo rendimento dos alunos e suas dificuldades em assimilar os conteúdos de programação destacam-se o precário embasamento lógico-matemático dos estudantes e a falta de experiência prévia em programação. A fim de promover um primeiro contato com programação para os alunos, antes do início das aulas, foi realizado um projeto de extensão no IFBA, campus Jacobina, onde os alunos ingressantes no Curso Técnico Subsequente de Informática participaram de um curso introdutório de programação, utilizando a ferramenta Scratch.

The Amorality of Public Corporations
Authors: Hazelton James ,   Philosophy Documentation Center
Published: January 2020

We consider whether public corporations can be ethical, using the notion of corporate social responsibility (CSR). We distinguish between ‘weak’ CSR (where corporate profitability is enhanced by pursuing social and environmental objectives) and ‘strong’ CSR (where it is not) and consider four possible positions in relation to strong CSR. First, CSR is unnecessary – good ethics is synonymous with good business. Second, CSR is unethical as the government is responsible for intervention in markets. Third, CSR is ethical and is being implemented by corporations. We find none of these positions convincing and argue a fourth position – CSR is ethical but impossible for corporations to implement due to competitive markets and the legal requirements of the corporate form. We conclude that public corporations are best considered amoral entities. In order to alleviate the inevitable negative social and environmental outcomes arising from corporate activities, we suggest strengthening the regulatory environment and using alternate organizational forms to conduct economic activities.
Does Liberalism Need Multiculturalism?
Authors: Schuster Anke ,   Philosophy Documentation Center
Published: January 2020

In this paper I will argue that liberal multiculturalism is neither a necessary nor a convincing extension of liberalism. In evaluating the two main strands of liberal multiculturalism, I will first analyse the approaches of Charles Taylor and Bhikhu Parekh as the main proponents of the version that focuses on the cultures themselves and raises the issue of the value of cultures in connection with public discourse. I will then turn to Amy Gutmann and Will Kymlicka as liberal multiculturalists who use the liberal norm of individual equality as a starting point. I will show that the arguments adduced in favour of liberal multiculturalism fail, due to the following shortcomings. Taylor’s approach is underspecified with respect to the relationship between the process of evaluating cultures and its outcome. Gutmann’s theory fails to bridge the gaps between the individual, cultural belonging and positive duties of the state. Parekh’s and Kymlicka’s theories lead back to liberalism. I conclude that the idea of cultural difference has little of substance to add to the liberal view of social justice.
The Object of History
Authors: Schinkel Anders ,   Philosophy Documentation Center
Published: January 2020

The phrase ‘the object of history’ may mean all sorts of things. In this article, a distinction is made between object1, the object of study for historians, and object2, the goal or purpose of the study of history. Within object2, a distinction is made between a goal intrinsic to the study of history (object2in) and an extrinsic goal (object2ex), the latter being what the study of history should contribute to society (or anything else outside itself). The main point of the article, which is illustrated by a discussion of the work of R. G. Collingwood, E. H. Carr, and G. R. Elton, is that in the work of historians and philosophers of history, these kinds of ‘object of history’ are usually (closely) connected. If they are not, something is wrong. That does not mean, however, that historians or even philosophers of history are always aware of these connections. For that reason, the distinctions made in this article provide a useful analytical tool for historians and theorists of history alike.
Violent Civil Disobedience and Willingness to Accept Punishment
Authors: Moraro Piero ,   Philosophy Documentation Center
Published: January 2020

It is still an open question whether or not Civil Disobedience (CD) has to be completely nonviolent. According to Rawls, “any interference with the civil liberties of others tend to obscure the civilly disobedient quality of one's act”. From this Rawls concludes that by no means can CD pose a threath to other individuals' rights. In this paper I challenge Rawls' view, arguing that CD can comprise some degree of violence without losing its “civil” value. However, I specify that violence must not be aimed at seriously injuring, or even killing, other individuals. This would contravene the communicative aspect of CD. The main claim is that what really is important is that the civil disobedients be willing to accept the punishment following their law-breaking behaviour. By doing so, they demonstrate the conscientiousness of their civilly disobedient action. This also shows that they are aiming for future cooperation with the State, and are expecting the State to be sensitive to their concern for the principles of justice.

My life as a writing professor and research librarian: The ideas that bridge the gap
Authors: Koors George
Published: January 2020

When I got into libraries, I looked forward to more one-on-one time with students. I had been a teacher at the college level for some time, and when I got a job as reference coordinator at American University, I saw an opportunity to have both large-group and one-on-one time with students.I staff a public-facing research desk, am embedded in first-year writing courses as their librarian, and teach first-year writing as a professor in the literature department. It is a wonderful balance, but it has taken time to learn how these identities interact. Over time, they have merged. This essay looks at that, and at some of the language I have used to understand that bridge between these roles. I hope to lightly tie this language to aspects of the ACRL Framework for Information Literacy for Higher Education.
Perspectivas de alunos de Bacharelado em Piano quanto ao uso do software MIROR- Impro para desenvolvimento de improvisação
Authors:   UDESC, Hamond Luciana , Addessi Anna Rita ,   Universidade de Bologna
Published: January 2020

Estudos de pesquisa recentes forneceram evidências sobre os benefícios do uso de tecnologia, quando utilizada, para aprimorar os aspectos específicos na aprendizagem de instrumento e canto, no contexto de aulas individuais. A aplicação de tecnologia pode gerar tipos de feedback adicionais ao provido pelo professor, comumente encontrado em aulas individuais. Tipos de feedback adicionais seja visual em tempo real ou visual combinado com auditivo em tempo posteriori aumentam a consciência do aluno sobre seu processo de aprendizagem. A improvisação é uma prática comum entre os licenciandos, pois é uma das habilidades funcionais essenciais para a atuação com professores na escola básica. No entanto, a improvisação pode ser um desafio para os bacharelandos, que têm o piano como instrumento principal em aulas individuais em que o foco está na interpretação pianística de repertório solo de diferentes períodos. O objetivo desta pesquisa é investigar o desenvolvimento da improvisação com alunos regulares do curso de Bacharelado em Piano de uma instituição de ensino superior brasileira, com o uso da interação reflexiva com o software MIROR-Impro. Dois alunos de bacharelado tiveram duas sessões com tecnologia registradas em vídeo; duas entrevistas semiestruturadas foram conduzidas a fim de compreender as perspectivas dos alunos quanto ao uso dessa tecnologia. Os relatos dos bacharelandos auxiliam na compreensão sobre a aplicação do software MIROR-Impro, destacando seus benefícios e suas limitações, para o desenvolvimento de improvisação em instrumentos de teclado.
