Authors: Binawati Ariesa Restianti , Bachri Bachtiar S , Arianto Fajar
Published: December 2020

Pronunciations of Chinese that are different from Indonesian pronunciation make beginner learners feel difficult and the need for companions in learning Mandarin. Spelling mistakes make meaning mistakes in Chinese. This requires a language learning model. The Cognitive Academic Language Learning Approach(CALLA) model is a language learning model for the development of foreign language skills according to native speakers. So the CALLA model is used for learning Chinese in order to practice self-directed learning and Mandarin phonetics. This study aims to determine the effectiveness of the CALLA model in Chinese learning in 10th grade. The research method used was a quasi-experimental study in 10th grade with data collection in the form of a response questionnaire to assess learning independence and a performance assessment rubric to assess Mandarin phonetics and then analyzed by using the independent sample t-test. The results of t-test are 0.00<0.05 in phonrtic aspect and 0.014<0.05 in self-directed learning. This suggests that the Cognitive Academic Language Learning Approach Model is effectively used ini the 10th grade Mandarin learning in the phonetics and self-directed learning aspect.

Authors: Lima Francisco José de , Vieira Gonçalves Bruna Maria
Published: December 2020

As discussões acerca da formação inicial e prática docente são sempre muito latentes, considerando a complexidade dos processos de ensino e de aprendizagem e o papel desempenhado pelo professor no contexto educacional. O presente artigo tem como objetivo refletir sobre a importância do Programa Institucional de Bolsas de Iniciação à Docência – PIBID para a constituição da práxis docente, vislumbrando a (re)elaboração do ensino de Matemática, com ênfase na utilização de jogos como estratégia metodológica. Para tanto, o estudo de abordagem qualitativa, recorreu a revisão bibliográfica e ao levantamento de estratégias de ensino, desenvolvidas por um grupo bolsistas vinculados ao PIBID/Subprojeto Matemática do IFCE campus Cedro. Nos limites desse artigo é discutida a utilização de jogos como possibilidade metodológica para ensinar e aprender Matemática básica. O estudo mostra-se relevante pela possibilidade de repensar o ensino de Matemática e fortalecer as discussões acerca da formação inicial do professor, tendo o PIBID como pano de fundo. Constatou-se que os jogos foram utilizados como recursos didáticos para trabalhar conteúdos da Matemática Básica, como as quatro operações fundamentais, em virtude do déficit de aprendizagem dos alunos no que tange a esses conhecimentos. Conclui-se que as ações desenvolvidas pelos bolsistas no âmbito do PIBID podem contribuir para a (re)elaboração do ensino de Matemática, por ser um espaço de reflexão e experiência de práticas docentes, que fortalece as licenciaturas e a formação inicial do professor.

A Phase 1 Randomized Dose-Escalation Study of a Human Monoclonal Antibody to IL-6 in CKD
Authors: Nowak Kristen L. , Kakkar Rahul , Devalaraja Matt , Lo Larry , Park Wansu , Gobburu Joga , Kling Douglas , Davidson Michael , Chonchol Michel
Published: December 2020

Background

Chronic systemic inflammation is highly prevalent in patients with CKD (measured as an elevated high-sensitivity C-reactive protein, hsCRP) and independently associated with cardiovascular events and all-cause mortality. An IL-6 blocker to suppress inflammation represents a potential novel paradigm to reduce cardiovascular risk in CKD.

Methods

A phase 1 trial of ziltivekimab, a fully human mAb against IL-6, was conducted in patients with moderate-to-severe nondialysis-dependent CKD (eGFR of 20–60 ml/min per 1.73 m2) and evidence of chronic inflammation (hsCRP level >2 mg/L over two consecutive measurements). Three cohorts of n=4 (3:1 active:placebo) were blindly randomized to a single dose of ziltivekimab (5 mg, 15 mg, and 50 mg subcutaneous injection), and followed for 12 weeks for safety and pharmacokinetic/pharmacodynamic assessments, with an additional 20 weeks for safety and antidrug antibody assessments.

Results

Participants were 67±11 years old; baseline eGFR: 40±13 ml/min per 1.73 m2; baseline hsCRP: 5.0±2.5 mg/L. Dose escalation was approved, and all adverse events were within the expected range for a CKD population with chronic inflammation. No serious adverse events were reported in any active cohort. hsCRP levels were substantially reduced with ziltivekimab. Of participants, 100% achieved suppression of hsCRP to <2 mg/L with the 15 mg and 50 mg dose, and several patients had undetectable levels of hsCRP with the 50 mg dose. The mean t
1/2 ranged from of 45 to 65 days.

Conclusions

In adults with moderate-to-severe CKD and evidence of chronic inflammation, a single-injection of the IL-6 inhibitor ziltivekimab was safe and highly effective at suppressing hsCRP over 12 weeks.

Causing Security Threat to Host State by Refugees: Context of Rohingya Refugees in Bangladesh
Authors: Rahman Md. Zillur , Dodul Dilshad Hossain
Published: December 2020

Bangladesh has been the host state of a large number of Rohingya refugees since August 2017. Rohingya, An ethnic minority group of Rakhine state, Myanmar, have been fleeing to Bangladesh after the Myanmar army started an ethnic cleansing on that area in august 2017. Since then, Bangladesh has been hosting around 1.1 million Rohingya refugees till now. In the first three months of the crisis, the majority arrived. During the first half of 2018, an estimated 12,000 people entered Bangladesh. Women and children are the vast majority in Bangladesh, and more than 40 percent are under 12 years of age (UNHCR 2020). As per the latest update of UNHCR, 860,243 Rohingya refugees are living in 187,534 households inside the camps (UNHCR 2020). After three years of this influx, Bangladesh is bearing the burden of Rohingya refugees and repatriation from Bangladesh is a far cry from reality. As (Mallick 2020) explain that, due to China and India's rising economic and strategic interests in repatriating the Rohingya refugees to the Rakhine State, Myanmar, foreign and regional organizations were unable to take any visible action. Organizations such as the United Nations, OIC, ASEAN, and other regional bodies have struggled to put pressure on Myanmar to take back Bangladeshi Rohingya refugees.
Translatability of Metaphors in the Dubbing of Animation Songs from English into the Egyptian Dialect
Authors: Tahseen Musleh Maysa’ Musleh
Published: December 2020

This research paper examined the ways how translators translated metaphors in the dubbing of animation songs and measured the degree of loss occurred in rendering metaphors from English into Arabic; these two languages are culturally and linguistically distinct languages. This study employed descriptive qualitative methods. The data used in this research were metaphors of songs from three animated musical movies: Beauty and the Beast, Tangled, and Pocahontas. This paper analyzed the translation of metaphors depending on the cognitive theory proposed by Mandelblit (1995). The results proved that even though translating metaphors in animation songs was a laborious process, they did not always cause a problem of untranslatability; on the contrary, translators can render metaphors from English onto Arabic without a significant loss in terms of meaning and sound patterns. Compensation in kind and compensation in place helped to achieve the translatability of metaphors in cartoon films’ songs. The analysis of source and target metaphors revealed that there were three translation procedures used to translate metaphors in animation songs, namely: replacing the source metaphor with a target metaphor (substitution), translating the metaphor into sense (paraphrasing), and using literal translation.

The study is an out breaking study in the context of COVID-19; since this examined the gap between customer perception and service quality of banking sector of Sri Lankan during the COVID-19. As community spread of the coronavirus (COVID-19) proliferates, alternatives to in-person banking and physical exchanges are looking more and more attractive. Further; the World Health Organization (WHO) has advised people to use contactless payment and avoid handling banknotes as much as possible, since the coronavirus may continue to live on banknotes for days, accelerating spread of the disease(World Health Organization, 2020). The study employed the SERVQUAL model (Parasuraman et al. 1985),which is used to measure customer satisfaction, and the effect of these dimensions (tangibles, responsiveness, empathy, assurance and reliability, access) on customer satisfaction was measured. For each dimension how the banks had ensured the quality during the pandemic was identified using primary and secondary sources and its relationship to the customer satisfaction was empirically tested.

Authors: Gomes da Silva Adriana , Castagna Molina Monica
Published: December 2020

Este artigo busca compreender a Cultura como matriz formativa na Licenciatura em Educação do Campo da Universidade de Brasília (LEdoC/UnB) enfatizando-se as potencialidades do trabalho com o Teatro Político e o Vídeo Popular e suas contribuições para a práxis formativa de educadores do campo na elevação de seus níveis de consciência política. Aspectos como a complexidade dos conceitos de Cultura produzidos historicamente, o legado do Movimento de Cultura Popular, do Centro de Cultura Popular e a atuação do Movimento dos Trabalhadores Rurais Sem Terra por meio da Educação e da Cultura são ressaltados como fundamentais neste trabalho para se compreender as bases históricas e epistemológicas que orientam a Licenciatura em Educação do Campo, especialmente na área de Linguagens, no trabalho estético do componente de Artes. Após a análise da LEdoC, compreendemos que as experiências estéticas e a práxis formativa com as linguagens artísticas desenvolvidas nessa licenciatura contribuem para a auto-organização e atuação dos educandos, tanto nas escolas como nas comunidades. Asistematização e a análise dessas experiências colaboram para os processos de formação, ensino e aprendizagem voltados às escolas do campo e às comunidades envolvidas com a perspectiva de uma educação omnilateral na busca da hegemonia da classe trabalhadora e da transformação social.
Educação ambiental à luz do referencial curricular do Paraná: limites e ausências
Authors: Souza Aline Sirlene de , Monteiro Magali De Fátima , Maia Jorge Sobral da Silva
Published: December 2020

A Educação Ambiental, ao longo dos últimos anos, tem sido silenciada nos documentos oficiais, principalmente na Base Nacional Comum Curricular (BRASIL, 2017) que a secundarizou como um tema contemporâneo transversal, estando à mercê do engajamento dos Sistemas Educacionais para a implementação de um currículo que inclua essa temática como prática social. Levando em conta essas considerações, o presente artigo teve por objetivo analisar a inserção da Educação Ambiental no Referencial Curricular do Paraná (PARANÁ, 2018), o modo como ela se apresenta, bem como identificar nesse documento termos que se referem à Educação Ambiental e suas relações com a tendência Crítica. Optamos por utilizar a pesquisa documental e análise de conteúdo e identificamos a falta de clareza e compromisso significativo centrados em uma perspectiva crítica, emancipatória e transformadora dos educandos. Neste sentido, evidenciamos a articulação da Educação Ambiental mais explícita na Educação Infantil e à medida que o nível de escolaridade aumenta, esta especificidade da educação formal abordada como um dos temas contemporâneos vai se descaracterizando e limitando-se, somente a algumas disciplinas. Também constatamos que o Referencial poderia abordar a Educação Ambiental de forma mais ampla, explícita, integrada, na perspectiva da totalidade em toda Educação Básica, uma vez que esse documento se constitui num fio condutor para ancorar o processo ensino-aprendizagem.

Do que era permitido ler às avaliações de leitura no Brasil: tensões e desafios
Authors: Dias Flávia Brito , Ens Romilda Teodora , De Oliveira Nagel Jaqueline Salanek
Published: December 2020

O artigo analisa tensões e desafios do processo de leitura no Brasil, desde o queera permitido ler até às avaliações institucionais. Optamos pela realização de pesquisa de abordagem qualitativa, exploratória, com vistas a levantar aspectos que indicam como a leitura vem sendo retratada em avaliações institucionais, como o Programa Nacional de Avaliação dos Estudantes (PISA, 2019), a Prova Brasil e o Sistema Nacional de Avaliação da Educação Básica (SAEB, 2018), na pesquisa Retratos da leitura no Brasil (2016) e Indicador de Analfabetismo Funcional (INAF, 2018). Primeiramente, trazemos uma reflexão sobre a leitura a partir da sua “instabilidade”, tomando as decisões políticas como “constantes sociais”. Em seguida, apontamos que políticas públicas encaminharam a leitura, demonstrando como se estruturam os direcionamentos no Brasil, após a Constituição de 1988. Na sequência, constatamos a descontinuidade nas políticas educacionais, nos projetos de incentivo à leitura, na exclusão de acesso das classes sociais economicamente frágeis, na responsabilidade do Estado, que, entre outros aspectos, evidencia a não atenção dos poderes públicos para a formação de leitores. Os resultados indicam que os programas de leitura voltados à educação básica, no Brasil, traduziram-se pela seletividade desenhada pelas reformas educacionais, desde o período colonial. Porém, suportes e práticas de leitura transpuseram o tempo e compuseram as experiências de leitura que se apresentam hoje. No entanto, estudos se fazem necessários para que indiquem habilidades significativas de leitura que ainda não são garantidas a todos os estudantes da educação básica.

IMPLEMENTASI PENGAMANAN DATA MENGGUNAKAN METODE KRIPTOGRAFI HILL CIPHER DAN STEGANOGRAFI LEAST SIGNIFICANT BIT (LSB) PADA MEDIA CITRA DIGITAL
Authors: Doo Samy Yeverson , Tena Silvester , Ndolu Varly M
Published: December 2020

Keamanan dalam pertukaran data menjadi hal yang mutlak diperlukan saat ini. Salah satu cara melakukannya adalah dengan menggunakan kriptografi. Kekuatan utama kriptografi adalah mengacak pesan sehingga sekalipun pesan tersebut dapat disadap tetapi tidak serta merta dapat dibaca. Hal ini sekaligus menjadi kelemahannya karena pesan yang acak tersebut bisa diduga berisi informasi penting yang menarik untuk dianalisa lebh jauh. Untuk mengatasi kekurangan tersebut maka steganografi menjadi hal menarik untuk dikombinasikan. Penggabungan metode Hill Cipher dan metode Least Significant Bit (LSB) dapat memberikan proteksi ganda pada data dalam sebuah gambar atau citra digital.

Hasil penelitian menunjukan bahwa citra  yang sudah melalui proses steganografi LSB terlihat sama dengan citra asli sehingga sangat sulit dibedakan. Nilai MSE dan PSNR citra hasil stego terbaik dihasilkan dengan nilai MSE 0.000306 dan nilai PSNR 83.305 dB. Bila tanpa attack (noise), hasil kombinasi pada pesan dengan metode kriptografi Hill Cipher dan metode steganografi LSB berjalan baik. Pada saat penambahan attack berupa noise salt and pepper secara kualitatif terjadi perubahan pada citra. Nilai MSE dan PSNR terendah yakni MSE 6.4620 dan PSNR 40.061 dB.

Published: December 2020

This research presents an automation process of controlling room temperature based on the number of people detected in a room. The system consists of a single board raspberry pi computer, esp8266 micro controller, pi camera, and an infrared module. This research is divided into two parts, namely object detection using Raspbery Pi and Tensorflow and Open CV libraries and controlling air cooling system (ACS) using esp8266 and infrared modules by transmitting hexadecimal AC control codes. The ACS temperature is divided into four levels with a minimum value at 18o C and a maximum at 24o C. System testings were carried out in an empty room and a room with a capacity of 50 people that is fully occupied. The results show that the system is able to detect the number of people in the room and control the ACS, but under certain conditions some objects are not detected because the position and camera tilt is not optimal.

ABSTRACT

In ensuring the reliability of electrical power distribution, distance relays as the main protection relays on the transmissiom line 70 kV Bolok - Maulafa must be able to detect and localize existing disturbances. Distance Rele works by comparing the impedance of the line (fault impedance) with the installed impedance (tuning impedance). This research was conducted to see whether the current settings are in accordance with the provisions in the introductory Protection and Control Handbook. This evaluation is carried out by comparing the settings attached to the tuning conditions set out in the Doc: PDM / SGI15: 2014 which are then simulated using DigSilent 15.1.7 to see the distance relay range based on that adjustment.From the evaluation results, the impedance setting by PT.PLN is no longer in accordance with the existing provisions and for setting the trip time in accordance with the provisions. Based on the calculation results of the new settings (according to the standard) distance relay, the value of the new settings for zone 1 and zone 2 of the Bolok - Maulafa conveyor bay is 4.69870.18⁰ sec.ohm and 13.65870.18⁰ sec.ohm. As for the conductor of Maulafa - Bolok, it is 4,26470.18⁰ sec.ohm and 6,07670.18⁰ sec.ohm.

ABSTRAK

Tujuan dari penelitian ini adalah untuk mendesain suatu aplikasi tuner sasando yang memiliki tingkat akurasi yang tinggi dalam mendeteksi frekuensi fundamental dari jenis sasando 32 senar menggunakan Algoritma Fast Fourier Transform (FFT) dan Harmonic Product Spectrum (HPS). Tingkat akurasi yang tinggi ditentukan dari resolusi frekuensi yang tinggi. Menurut Lourde, M (2009), kemampuan telinga manusia untuk membedakan bunyi adalah pada resolusi 0.5 Hz. Manusia tidak mampu membedakan bunyi jika resolusi atau selisih dua frekuensi yang berdekatan lebih kecil dari 0.5 Hz. Oleh karena itu, aplikasi yang didesain harus mampu memberikan resolusi 0.5 Hz. Berdasarkan hasil simulasi, Aplikasi Tuner sasando yang telah dibangun mampu memberikan output resolusi 0.5 Hz. Selain itu, aplikasi yang dibangun juga dapat menampilkan spektrum frekuensi dan mampu memberikan informasi apabila frekuensi dari senar yang sedang dituning sudah tepat pada frekuensi fundamentalnya. Tidak hanya itu, apabila frekuensinya masih kurang atau sudah melewati frekuensi dasarnya, maka akan ditampilkan juga pada outputnya.

ABSTRAK

Sistem pengaman kendaraan bermotor bawaan pabrikan seperti kunci stir telah banyak digunakan. Akan tetapi pencurian kendaraan bermotor masih terjadi karena kunci stir dapat dilumpuhkan dengan kunci T. Menurut Badan Pusat Statistik (BPS) terjadi sekitar 35.226 kasus pencurian kendaraan bermotor di tahun 2017 dan 38.741 kasus di tahun 2018. Dari data tersebut menunjukkan bahwa setiap tahun angka pencurian semakin meningkat. Salah satu penyebab meningkatnya pencurian adalah satu-satunya pengaman motor hanya kunci stir tersebut. Selain itu sistem tersebut tidak dilengkapi pengaman yang dapat memantau posisi kendaraan. Oleh karena itu pada penelitian ini telah dibuat sistem pengaman kendaraan bermotor berbasis GSM dan mikrokontroler. Alat tersebut dapat mengaktifkan dan menonaktifkan mesin kendaraan dengan cara memutus arus ke koil, serta dapat mengaktifkan dan menonaktifkan alarm dari jarak jauh. Keunggulan tambahan dari alat ini adalah terdapat fitur yang dapat memberitahukan posisi kendaraan dalam bentuk koordinat yang dapat diakses menggunakan aplikasi Googlemaps yang terdapat di smartphone. Penelitian ini menyajikan rancang bangun sistem pengaman kendaraan bermotor berbasis GSM dan mikrokontroler. Hardware sistem terdiri dari lima komponen alat utama yaitu mikrokontroler Arduino, GSM Shield, Modul GPS, Driver Relay, IC4017. Software pemrograman menggunakan Arduino IDE versi 1.8.5, dimana program dirancang untuk menonaktifkan dan mengaktifkan kendaraan maupun alarm serta mengirimkan koordinat melalui perintah SMS (Short Message Service).
