Optimasi Sistem Penempatan Magang Menerapkan Algoritme Genetika
Authors: Wicaksono Satrio Agung 
Published: February 2019

Magang merupakan proses yang penting dalam proses belajar mengajar di SMK. Secara spesifik magang di SMK disebut Prakerin (Praktek Kerja Industri). Penempatan magang harus memerhatikan kompetensi siswa, kuota dari perusahaan, kesesuaian jurusan dengan lowongan, dan penghasilan orang tua. Penempatan magang secara manual selama ini memakan waktu, sehingga kurang efisien. Oleh karena itu, penelitian ini fokus mengembangkan aplikasi dengan menerapkan pendekatan Algoritme Genetika untuk mempermudah dalam menentukan penempatan magang dengan menerapkan aturan yang berlaku. Algoritme Genetika dinilai sebagai algoritma yang relevan dan solutif untuk diterapkan dalam penyelesaian masalah optimasi kompleks. Masalah yang dimaksud umumnya adalah masalah yang sulit dilakukan dengan menerapkan metode konvensional. Algoritme Genetika memberikan hasil yang lebih baik untuk setiap iterasi pencarian solusi. Hasil fitness terbaik dengan nilai 0.0014286 diperoleh pada jumlah individu 200, jumlah generasi 200, persentase crossover 50% dan mutasi 10%. Hasil validasi dengan pihak SMK menyatakan bahwa sistem ini mudah untuk digunakan dan bermanfaat bagi pihak SMK, dengan rata-rata persentase kualitas sistem 82,5%. Algoritme Genetika efektif untuk diterapkan pada studi kasus penjadwalan atau penempatan magang yang memiliki karakteristik data yang kompleks. AbstractInternships are an important component of teaching and learning activities in vocational high schools (SMK). Specifically the internship in SMK is called Prakerin (Industrial Work Practice). The internship placement should considering student competence, number of vacancies, the suitability of majors with vacancy, and the income of the parent. During this time, manual internship placement takes more time, so less efficient. Therefore, this research tries to approach using Genetic Algorithm to make it easier in determining the internship placement by applying the applicable rules. The Genetic Algorithm is judged as the right algorithm used in solving complex optimization problems, which is difficult to do by conventional methods. The Genetic Algorithm provides better results for each iteration of the solution search. Best fitness results with value 0.0014286 obtained on the number of individuals 200, the number of generation 200, the percentage of crossover 50% and the mutation 10%. Validation results with the SMK stated that the system is easy to use and beneficial to the SMK, with an average percentage of system quality about 82.5%. Genetic Algorithms are effective to apply to scheduling case studies or internship placements that have complex data characteristics.

Authors: Silva Larissa Goulart da , Vial Ana Paula Seixas , Sarmento Simone 
Published: February 2019

Abstract
The Language without Borders (LwB) Programme is an educational policy which aims at promoting English learning at universities as well as promoting opportunities for teacher development. LwB teachers have to prepare their own English for Academic Purposes (EAP) teaching materials. Taking this into account, we seek to understand how the LwB Programme prepares these teachers to create EAP materials and if they encounter any difficulties. A needs analysis was carried out through online surveys and semi-structured interviews. The former was sent to LwB teachers from all over Brazil, and the latter was conducted with teachers from one university. Based on the results we suggest some topics that could be addressed in the pedagogical meetings to address these teachers’ needs.

Resumo
O Programa Idiomas em Fronteiras (IsF) é uma política educacional que busca promover a aprendizagem de inglês na universidade e ser uma oportunidade de formação de professores, pois os professores-bolsistas do IsF devem preparar seu próprios materiais didáticos de Inglês para Fins Acadêmicos (IFA). Levando isso em consideração, buscamos entender como o Programa IsF prepara esses professores para elaborar materiais de IFA e se encontram dificuldades. Para tanto, foi conduzida uma análise de necessidades através de questionários online e entrevistas. Os questionários foram enviados para professores IsF de todo o Brasil e as entrevistas foram realizadas com professores de uma universidade. Com base nos resultados, sugerimos tópicos que podem ser trabalhados nas reuniões pedagógicas para responder às necessidades dos professores.

O vídeo-digital em uma proposta de leitura em língua materna sob um enfoque discursivo
Authors: Raimo Luciana Cristina Dias di 
Published: February 2019

Considerando o impacto das tecnologias digitais em práticas de leitura, apresentaremos uma abordagem discursiva de um vídeo disponibilizado no sítio eletrônico de Veja a respeito da cobertura da morte de Eduardo Campos. Na prática de leitura implementada, vale destacar que o vídeo nos permitiu problematizar alguns aspectos: (i) o efeito de evidência produzido pelo/no jornalismo eletrônico como modalidade na qual a informação é sintética e capaz de atingir sujeitos-leitores em larga escala; (ii) o processo de textualização do vídeo que se constitui não por um registro de uma série de ações, mas sim a partir da combinação de cenas congeladas do velório que organizam relações de contradições em torno do visível (cenas do velório) e do dito.

Published: February 2019

Este artigo analisa como os textos multimodais e as metafunções estão inseridas no LD de espanhol. A pesquisa é centrada nos pressupostos teóricos da Linguística Sistêmico-Funcional de Halliday (1978), base teórica dos estudos da Teoria da Semiótica Social/Multimodalidade (KRESS; van LEEUWEN, 2006) e Análise de Clusters (BALDRY; THIBAULT, 2006), que definem o texto multimodal como aquele que tem seus significados realizados por várias semioses. O artigo configura-se como uma pesquisa de natureza qualitativa em que se privilegia a (re)interpretação de dados. As análises permitem reflexão sobre a composição dos textos multimodais no LD, demonstrando as peculiaridades inerentes à sua composição e como a língua é entendida como parte do contexto sociocultural.

Authors: Reichow Sandro Laércio , Dagnoni Carini , Maieski Amanda 
Published: February 2019

RESUMOImunoterapia com nivolumabe para o tratamento de segunda linha para câncer de pulmão avançado demonstrou menor toxicidade e melhores desfechos, em comparação com quimioterapia. Quando ocorrem, os eventos adversos são geralmente imuno-mediados, podendo acometer qualquer órgão e, na maioria das vezes são manejáveis, entretanto raros casos podem ser fatais. Há poucos relatos na literatura de necrólise epidérmica tóxica ocasionada por nivolumabe. O objetivo do presente relato de caso é descrever a história clínica de uma paciente que desenvolveu esta reação após uso desta medicação e discorrer uma breve revisão da literatura sobre sua etiologia e medidas terapêuticas, tendo em vista sua raridade e gravidade. São parte essencial do sucesso do tratamento a detecção precoce dos sintomas/sinais e rápido manejo dos mesmos.
Exploring the link between anabolic-androgenic steroids abuse for performance improvement and hepatocellular carcinoma: a literature review
Authors: Coelho Rafael Corrêa , dos Santos Fernandes Gustavo , Sternberg Cinthya 
Published: February 2019

ABSTRACT
Introduction: Hepatocellular carcinoma (HCC) corresponds to 90% of primary malignant liver cell carcinomas and is a leading cause of cancer-related death worldwide.
Objective: This compilation of cases aimed to identify evidence of correlation between anabolic androgen steroids (AAS) abuse for performance improvement by healthy subjects and HCC.
Methods: We performed a literature review and identified 935, 1148, 12 and 3 articles in Pubmed, Embase, Scopus and Lilacs, respectively. Only studies, reviews and case reports evaluating the association between androgens and hepatocarcinoma were included with no restrictions in time span or language. Further on, we excluded studies and case reports which patients were receiving therapeutic androgens and collected data only of those reporting androgen intake to improve physical performance.
Results: Six articles fulfilled the inclusion criteria, excluding the duplicates. HCC onset after AAS abuse seems to occur at earlier ages than those related to chronic hepatitis B/C, chronic alcohol consumption and nonalcoholic steatohepatitis (NASH). Timeframe ranged from two to seven years in the cases reports presented here. Many AAS subtypes were used by patients depicted in the case reports, so it is difficult to conclude if a specific AAS is safer or more harmful than the other. Carcinogenic mechanisms are poorly understood, but pre-clinical evidence shows that androgen receptors and oxidative stress may play a pivotal role in its development.
Conclusion: The evidence that HCC has been linked to long term AAS abuse for performance improvement is scant but some association is suggested. AAS must be taken only under specialized supervision and the putative correlation with HCC calls for public policies to make high risk populations aware of the risks of misuse and self-administration.
