A estrutura do verbo em Apinayé
Authors: Albuquerque Francisco Edviges 
Published: August 2017

Neste estudo, descrevemos e analisamos a estrutura do verbo na língua Apinayé, falada por aproximadamente 1.300 pessoas habitantes em sete aldeias situadas no extremo norte do Tocantins. Adotamos critérios morfológicos, sintáticos e semânticos, e daremos prioridade, em primeiro lugar, aos critérios morfossintáticos, visto que os verbos ocupam posições estruturais de dois tipos, dependendo do modo de indicar o objeto. Segundo Ham (1979: 01), os verbos em Apinayé possuem duas formas de raiz: a forma comprida, que ocorre somente quando o verbo é seguido de outras palavras na mesma frase; e a forma curta, na qual o verbo aparece em posição final na frase. Os verbos da primeira classe indicam, através do prefixo, que o objeto está implícito; já a forma curta tanto é usada com objeto explícito quanto com objeto implícito, quando as duas formas de prefixo ocorrem.
Concordância verbal de número em Kaingáng
Authors: D'Angelis Wilmar da Rocha 
Published: August 2017

À primeira vista, é possível pensar que, na língua Kaingang, a concordância de número no verbo se faz por dois padrões: um para os verbos transitivos, outro para os intransitivos. Mas é justamente o fato de esses padrões fazerem coincidir o tratamento do verbo transitivo ao Objeto Direto (O) com o tratamento do verbo intransitivo ao Sujeito (S) da intransitiva que nos levam a concluir tratar-se de um único padrão, que superficialmente faz variar a concordância ora com Sujeito, ora com Objeto Direto. A concordância de número, no verbo, realiza-se morfologicamente por dois modos: alguns verbos podem ser reduplicados (reduplicação da última sílaba) enquanto outros possuem uma forma própria para o singular e outra para o plural. Essa comunicação pretende apontar algumas pistas para a investigação de todos os processos de construção do plural e de concordância de número em Kaingang.
Prefixos relacionais em Jê e Karajá
Authors: Ribeiro Eduardo Rivail 
Published: August 2017

Este trabalho compara os chamados ‘prefixos relacionais’ em diferentes línguas do tronco Macro-Jê, dando ênfase especial às famílias Jê e Karajá. Prefixos relacionais, que marcam a contigüidade ou nãocontigüidade do núcleo de um sintagma com relação a seu determinante, ocorrem em pelo menos cinco das doze famílias do tronco Macro-Jê: Jê, Boróro, Ofayé, Karirí (Rodrigues 1994) e Karajá (Ribeiro 1996). Tal mecanismo ocorre também em línguas Tupí e Karíb (Rodrigues 1994), o que pode sugerir que sua presença em diversas famílias do tronco Macro-Jê seja antes um fenômeno areal do que evidência de origem genética comum. A comparação preliminar entre Karajá e Jê que apresentamos aqui, no entanto, sugere que prefixos relacionais podem ser reconstruídos para a língua ancestral comum às duas famílias, corroborando, assim, a hipótese acerca da unidade genética de pelo menos parte do tronco.

Artesão ou guasqueiro: Uma discussão sobre identidade e Memória
Authors: Machado Juliana Porto , Colvero Ronaldo Bernardino 
Published: August 2017

O artesanato em couro, guasquería, é uma prática tradicional que se mantém na contemporaneidade através das transformações de significados dos objetos produzidos e pela adoção de novos materiais de produção. As técnicas de produção são manuais, o que a caracteriza como artesanato. Possui forte ligação com a zona rural, principalmente com as atividades equestres. Nosso objetivo foi promover a análise desse processo artesanal tradicional do artefato em couro (guasquería) na cidade de Jaguarão e sua influência na identidade de seus praticantes, levando em conta o saber/fazer do artesão/guasqueiro para compreender se houve modificações e como ocorre a conservação-transformação das técnicas de produção. A metodologia consistiu em uma proposta etnográfica através de entrevista semiestruturada com 04 artesãos/guasqueiro. Como principais resultados podemos destacar: a partir das narrativas de nossos informantes que todos os entrevistados viveram ou trabalharam na zona rural; persistem as técnicas tradicionais/contemporâneas e o modo de produção; continua o saber/fazer apreendido pela transmissão de conhecimento entre indivíduos que possuíam laços íntimos com o aprendiz; o meio urbano/rural em que a prática de guasquería é um artesanato “rural”, onde seus criadores vivem em espaço urbano; por fim, a visão do guasqueiro, em relação ao sua identidade, é de se considerar guasqueiro por trabalhar com couro cru e artesão por trabalhar de forma manual. Concluímos que os praticantes desse oficio se consideram guasqueiros, mas também, artesão. Em um diálogo não conflituoso. O eu guasqueiro e o eu artesão se complementam.

Published: August 2017

Abstract. Science and technology have been rapidly evolved in some fields of knowledge, including mathematics. Such development can contribute to improvements on the learning process that encourage students and teachers to enhance their abilities and performances. In delivering the material on the linear equation system with two variables (SPLDV), the conventional teaching method where teachers become the center of the learning process is still well-practiced. This method would cause the students get bored and have difficulties to understand the concepts they are learning. Therefore, in order to the learning of SPLDV easy, an interesting, interactive media that the students and teachers can apply is necessary. This media is designed using GUI MATLAB and named as students’ electronic worksheets (e-LKS). This program is intended to help students in finding and understanding the SPLDV concepts more easily. This program is also expected to improve students’ motivation and creativity in learning the material. Based on the test using the System Usability Scale (SUS), the design of interactive mathematics learning media of the linear equation system with Two Variables (SPLDV) gets grade B (excellent), meaning that this learning media is proper to be used for Junior High School students of grade VIII.Keyword: SPLDV, Learning Media, Students’ Electronic Worksheet (e-LKS) *Judul ini telah dipresentasikan pada Seminar Nasional: Indonesian Students Conference on Science and Mathematics(ISCSM) 11-12 November 2015, Banda Aceh Indonesia

Published: August 2017

Abstract. Early detection of breast cancer is the first step in prevention that can be done by women, therefore when one is diagnosed with breast cancer, the appropriate treatment can be performed quickly and accurately. Early diagnosis of breast cancer can be a way of mitigation in preventing breast cancer through the use of mammography. Bureau of Radiology as said by The Joint Commission on Accreditation of Hospitals (JHCA) stated that one of the responsibilities of the radiology unit is to control the quality of service which aims to minimize the radiographic image repetition factor; as well as maximizes the quality of radiographic image. Quality control tests are an effort that is needed on the mammography X-ray diagnostics tools. This is done to maintain the quality of expected output. The parameters that are included within the radiation output are the magnitude of current and the voltage of tube that are produced; therefore they remained constant and correspond to the recommended standard. Bureau of Radiological Health, as said by JHCA mentioned that to control the quality of image which will minimize the radiographic image repetition and maximizes the quality of radiographic image. Therefore the radiation output will not be dangerous later. The early stage of the quality control test on the machine was conducted by setting all the filtrations which were placed to capture the x-ray on the x-ray plane tube with minimum value. Then, ionization chamber is placed on the test subject points; right after that the distance between it to the radiation source is noted. The x-ray film is place on a film on the compression table of the patient and the distance between film and the focus point is noted. This is then exposed using a target filter Mo/Mo by setting the current as well as variation the voltage and time. The standard voltage measurements are 20-33kVp. This data is from the observations of time exposure; the output value is then noted. The above procedure is conducted from the minimum voltage to the maximum voltage. The output ray is measured for each voltage. The same procedure is conducted to the target filter Mo/RH. The results obtained are that the greater the input voltage and current will subsequently produce greater doses, therefore the exposure has exceeded the standard limit 0.1 mHy with longer exposure time. The HVL density thickness on the mammography X-ray machine determined the quality of the beam and the doses of x-ray exposure on the mammography machine. The output stability of x-ray beam exposure in the mammography machine mode Mo/Mo still fulfill the standard which is the value of 69% Keywords: Quality Control, Sinar-X, mammography, Mp/Mo, Mo/RH
