Pengaruh Metode Penyeimbangan Kelas Terhadap Tingkat Akurasi Analisis Sentimen pada Tweets Berbahasa Indonesia
Authors: Husada Ivan Nathaniel , Toba Hapnes 
Published: August 2020

Nowadays internet access is getting easier to get. Because of the ease of access to the internet, almost all internet users have social media. Social media is widely used by users to call out their opinions or even to make complaints about a matter and also discuss a topic with other social media users. From many existing social media, one that is popularly used for that activity is Twitter. Sentiment analysis on Twitter has become possible because of the activities of these Twitter users. In this research, the authors explore sentiment analysis with bag-of-words and Term Frequency Inverse Document Frequency (TF-IDF) features extraction based on tweets from Indonesian Twitter users. The data obtained is in imbalanced condition, so that it requires a method to overcome them. The method for overcoming imbalanced dataset uses a resampling approach which combines over and under sampling strategies. The results of sentiment analysis accuracies with Naïve Bayes and neural networks before and after input data resampling are also compared. Naïve Bayes methods that will be used are Multinomial Naïve Bayes and Complement Naïve Bayes, while the Neural Network architecture that will be used as a comparison are Recurrent Neural Networks, Long Short-Term Memory, Gated Recurrent Units, Convolutional Neural Networks, and a combination of Convolutional Neural Networks and Long Short-Term Memory. Our experiments show the following harmonic scores (F1) of the sentiment analysis models: the Multinomial Naïve Bayes F1 score is 55.48, Complement Naïve Bayes is 51.33, Recurrent Neural Network is 75.70, Long Short-Term Memory is 78.36, Gated Recurrent Unit is 77.96, Convolutional Neural Network is 76.12, and finally the combination of Convolutional Neural Networks and Long Short-Term Memory achieves 81.14.

The occurrence of soil erosion in Wai Ela Watershed is related to natural factors such as geology, soil types, slope steepness, and land uses. This study aimed to estimate soil erosion rates and their spatial distribution in Wai Ela watershed, and the results were used to establish land rehabilitation practices. The study used a survey method with a flexible grid observation distance, and field data collection was conducted on 15 sampling areas representing 72 land units. The annual soil erosion rates of Wai Ela watershed were estimated by using RUSLE and GIS, and the results were corrected with 0,2547 (Talakua and Osok’s correction factor). The proposed land rehabilitation practices were established based on the tolerable soil erosion (T) values and CP maximum. The study results showed that the average annual erosion rates in Wai Ela watershed vary from light erosion (8,14 t/ha/yr) to very heavy erosion (381,70 t/ha/yr), while the tolerable soil erosion rates range from 4,60 t/ha/yr to 24t/ha/yr. The proposed land rehabilitation practices include enrichment of the existing unprotected areas (bare lands) with forest and fruit trees, planting cover crops and grasses, and mulching on agricultural land.

This research concludes that the Constitutional Court Decision Number 22 / PUU-XV / 2017 which mandates the legislators to revise the age-limit of marriage, is irrelevant in preventing child-age marriages. Indonesian marriage legal system continues to open up opportunities for deviations of the principle of age-limit of marriage through Dispensation of Marriage. This research finds the juridical development on Dispensation of Marriage on the type of marriage requiring Dispensation of Marriage, the applicant of Dispensation of Marriage, the authority to provide Dispensation of Marriage, and the administrative requirements to submit the Dispensation. Based on these developments, several factors that cause irrelevancy of the Constitutional Court Decision Number 22 / PUU-XV / 2017 in preventing child-age marriages are the absence of specific requirements in the application of Dispensation of Marriage to the court, the existence of the Principle of Freedom in procedural law, the voluntary nature attached in the request for Dispensation of Marriage, as well as the extension of provisions of applicants who can submit an application to the court.

Published: August 2020

Introduction: Breastfeeding practices of women working at the hospital are likely to be modified by the facilities and support that they receive at the hospital. This study was done to evaluate the breast feeding practices and to analyse important factors that are associated with exclusive breast feeding till six months among women working at hospitals in Kathmandu, Nepal
Methods: A total of 110 women, with a young child between the ages of six months and two years were recruited from two hospitals in Kathmandu. A predesigned structured, interviewer-administered questionnaire was used for data collection.
Results: The mean age of the mothers was 29.85 ± 3.68 years. Ninety seven (88.2%) women were aware about initiation of breastfeeding within first hour of birth but only 64 (58.2%) women could practice it. Most women 100 (90.9%) were aware about exclusive breastfeeding but only 18 (16.3%) could practice exclusive breastfeeding till six months. Mean duration of exclusive breastfeeding was 2.86 ± 2.00 months and 20 (18.2%) mothers practiced mixed feeding since birth. The participants whose babies had prelacteal feeding had significantly shorter duration of mean exclusive breast feed {1.92 ± 2.18 (S.D)} compared to those who did not have prelacteal feed {3.33 ± 1.74 (S.D)} (p = 0.001). Those who delivered by normal vaginal delivery, initiated breastfeeding within first hour of delivery, expressed breast milk and got feeding breaks were associated with longer duration of mean exclusive breast feed.
Conclusion: The breast feeding practices among working women at hospital is quite low compared to national statistics on IYCF. Breast milk expression and feeding breaks for lactating working women could improve feeding practices.

Published: August 2020

Introduction: The paediatric intensive care unit (PICU) takes care of critically ill paediatric patients. Regular evaluation of the outcomes of patients admitted to PICU is important to assess the effectiveness of various interventions. This study aimed to find the morbidity and mortality pattern of patients admitted to PICU of tertiary level Paediatric hospital of Nepal.
Methods: We conducted a retrospective, cross sectional observational study using the records of all the patients admitted to PICU of a tertiary level hospital from January 2017 to August 2017. We collected data on age, sex, geographical distribution, duration of PICU stay and the morbidity and mortality outcomes. Outcome is classified as transfer to ward, leave against medical advice (LAMA) and death. Data were analysed descriptively using SPSS version 23.
Results: Out of 358 patients admitted to PICU, the mean age was 1.83 years. Majority were infants (54.5%) with male:female ratio of 1.8:1. The major causes of PICU admission were respiratory disease (27.7%) followed by CNS disease (19.6%) and infections (17.3%). The average length of stay was 6.27 days. Overall mortality was 22.7%.
Conclusion: Respiratory infections were the primary cause of PICU admission and overall mortality rate was high at 22.7%. However, mortality rate was even worse for patients with multi-system involvement. We need prospective studies to examine the underlying reasons for mortality among patients with multi-system involvement.

Authors: Costa Danglares de Souza , Coelho Alex Almeida 
Published: August 2020

O presente artigo é a descrição dos impactos dos benefícios sociais na socioeconomia de comunidades rurais de Tefé (AM). As comunidades analisadas foram: Agrovila, Maranata, São Francisco, Agrovila da Emade, Boa Vontade e Bom Jesus. A amostra é composta por 61 domicílios e a análise tem caráter quanti-qualitativo. Utilizou-se a estatística descritiva para a elaboração e geração de resultados sobre os rendimentos e despesas, construindo assim parte da análise das realidades sociais e econômicas das comunidades. Essa etapa quantitativa levantou dados referentes às relações socioeconômicas da amostra. Já a qualitativa foi realizada por meio de entrevistas abertas que também complementaram os dados quantitativos. Os nomes citados nos dados qualitativos são fictícios para garantir a privacidade dos participantes. Os benefícios sociais contribuem de forma significativa para as famílias. O Bolsa Família e as aposentadorias são empregados na compra de vestuário, material escolar e alimentação. A aposentadoria ainda se aplica na compra de remédios, exames, viagens e bens. Possuir um cartão de benefício é garantia de crédito no mercado, pois são rendimentos mensais regulares, o que viabiliza poder de compra aos beneficiários. Portanto, de forma direta os benefícios sociais são elementos que possibilitam novos cenários na economia dos domicílios dessas comunidades rurais.

Published: August 2020

Este artigo tem como objetivo tratar as interfaces entre SUAS e o SISAN na efetivação dos Direitos Humanos de modo geral e, em particular do Direito Humano à Alimentação. Apresentamos uma abordagem qualitativa sobre o tema, resultante de trabalho de formação desenvolvido na Política de Educação Permanente dos/as trabalhadores/as do SUAS, através do projeto CapacitaSUAS /PE. Neste artigo as interfaces entre SUAS e o SISAN são apresentadas e analisadas a partir dos aspectos apontados pelos/as trabalhadores/as do SUAS a partir da realidade dos municípios em que atuam. O material para a análise foi levantado a partir do curso, SUAS e SISAN: A segurança alimentar e nutricional e a inserção no Sistema Único da Assistência Social, que foi ofertado na modalidade Ensino a Distância, com a participação de 381 cursistas. Para os/as trabalhadores/as a insegurança alimentar está diretamente relacionada a fome. O CRAS é apontado como principal equipamento, no entanto a resposta nos municípios é reportada a apenas duas ofertas, a do Programa Bolsa Família e aos benefícios eventuais. A intersetorialidade entre as políticas é tida como desafio e a integração no cotidiano dos municípios como frágil ou inexistente.
O processamento de múltiplas dependências não adjacentes em orações relativas no PB
Authors: Henrique Kessia Da silva , Name Maria Cristina Lobo 
Published: August 2020

Neste artigo, investigamos o processamento de dependências não adjacentes (DNAs) e suas diferentes configurações no português brasileiro (PB), por falantes adultos. DNAs são definidas como a co ocorrência de marcadores morfossintáticos e/ou fonológicos, com material interveniente, como em A menin-a, em que se observa a dependência entre o determinante e a marca de gênero feminino -a no nome, tendo o material interveniente menin- entre os itens dependentes. No PB, do ponto de vista estrutural, há ocorrências de DNAs do tipo aninhadas (A1 A2 B2 B1), em que os elementos codependentes A2 B2 “se aninham” entre A1 B1, como em OA1 carroA1 que osA2 mecânicosA2 consertaramB2 bateuB1; e DNAs do tipo alinhadas (A1 A2 B1 B2), em que os elementos dependentes estão em sequência imediata, como em OA1 mecânicoA1 consertouA2 osB1 carrosB1 que bateramB2. Resultados de dois experimentos com a tarefa de labirinto (maze task) revelaram tempo de leitura maior na condição aninhada, sugerindo que dependências nessa configuração causam maior demanda no processamento linguístico. As DNAs foram bastante exploradas no âmbito da aquisição da linguagem, mas pouco se sabe a respeito da habilidade de processamento dessas estruturas em adultos. O estudo em questão lança luz a respeito da discussão do processamento de múltiplas DNAs por adultos no PB e sobre os fatores envolvidos no processamento de múltiplas dependências.
The new neurocognitive science of language: innovative experimental design for studying syntactic and semantic processing in communicative settings, an interview with Katrien Segaerts
Authors: Calindro Ana Regina , Soto Marije 
Published: August 2020

Katrien Segaert is the head of the Neuroscience of Language lab at the School of Psychology at the University of Birmingham (UK), where she is also affiliated with the Centre for Human Brain Health. Her research deals with the major question of how syntax and semantic processing are instantiated in the brain within the context of communicative settings, and how the neurobiological circuitry for sentence processing changes throughout our lives. Her lab does experimental studies with a variety of techniques, ranging from EEG and fMRI to classical psycholinguistic methodologies. Her work has been really innovative in the ways she has managed to bring communicative context to experimental paradigms: participants engaged with avatars, or interacted with interlocutors while lying in the MRI scanner. Another series of her studies that have attracted some media attention are those involving aging adults: results have shown surprising correlations between language processing and fitness. She has agreed to talk to us about working with novel experimental methodologies in a highly interdisciplinary field.----------------------------------------------------------------------------------A NOVA CIÊNCIA NEUROCOGNITIVA DA LINGUAGEM: PARADIGMAS EXPERIMENTAIS INOVADORES PARA ESTUDAR O PROCESSAMENTO SINTÁTICO E SEMÂNTICO EM CONTEXTOS COMUNICATIVOS, UMA ENTREVISTA COM KATRIEN SEGAERTSKatrien Segaert é a coordenadora do laboratório de Neurociências da Linguagem da Escola de Psicologia da Universidade de Birmingham (Reino Unido) e afiliada ao Centro de Saúde do Cérebro Humano.

Published: August 2020

Introduction: Metal/graphene heterojunction structure has been one of the most crucial tools in the growth of high-performance Surface-enhanced Raman spectroscopy (SERS) platform, which is appropriate for sensing applications. In this research, we developed a SERS platform, graphene nanoribbons (GNRs) decorated silver nanoparticles (AgNPs) on cellulose paper substrate, in which GNRs was synthesized by wet chemical based on unzipping process of Multi-walled carbon nanotubes (MWCNTs), then GNRs hybridized with AgNPs through magnetron sputtering method.
Methods: The morphology of graphene nanoribbons coated-Ag (AgNPs@GNRs) was analyzed by field emission scanning electronic microscopy (FESEM) and transmission electron microscopy (TEM). The quality and thermal stability of GNRs were characterized using thermogravimetric analysis. Besides, its structure and quality were also characterized by Raman spectroscope.
Results: The results show that the unzipping process of MWCNTs to form GNRs was strongly affected by dispersing time and stirring temperature. The suitable condition creating the Graphene Nanoribbons using MWCNTs was the dispersing time of 10 mins in an acid environment, stirring in 30 mins at room temperature and in 45 min at 100°C. Moreover, SERS platform of AgNPs@GNRs exhibit the outstanding SERS signal enhancement with rhodamine 6G (R6G) low concentration of 10-5 M compared with pristine graphene and silver thin film. This could be attributed to the synergistic effect between AgNPs, GNRs and analyze molecules based on the enhancement of electromagnetic mechanism (EM) and chemical mechanism (CM), which plays a vital role in promoting the improvement SERS behavior.
Conclusion: Ag NPs assembled onto graphene nanoribbons/ cellulose paper substrate could also serve as SERS active substrates for practical applications in various fields at trace levels.

Published: August 2020

Both academics and practitioners have a substantial interest in understanding interest in understanding patterns in implied volatility that are recoverable from commodity futures option. Such knowledge enhances their ability to accurately forecast volatility embedded in these high risk option. This paper examines option-implied volatility contained in the heavily traded September corn futures option contracts for ten-year period, 1991-2000. We also test whether a “weekend effect” exists in the market for this contacts. We evaluate the performance of various measures widely employed in the literature to estimate historical volatility. We further report the nature of profit from a short straddle strategy which seek to exploit differences between option-implied and historical volatility.
