Published: March 2021

Saham merupakan surat berharga sebagai tanda atas bagian kepemilikan suatu perusahaan. Kepemilikan saham diperdagangkan di bursa saham untuk perusahaan terbuka. Pasar modal merupakan sebuah kegiatan yang mewadahi keinginan untuk berinvestasi. Trader mencari keuntungan dengan memanfaatkan pergerakan saham yang selalu mengalami perubahan fluktuatif dengan cara menggunakan analisis teknikal. Timbul masalah tentang cara trader memutuskan membeli sebuah saham dengan harga yang tidak pasti. Metode Brown’s Weighted Exponential Moving Average memiliki kelebihan yaitu tingkat akurasi yang lebih baik yang dirasa mampu untuk membantu masalah prediksi harga saham. Algoritme Levenberg-Marquardt memiliki kelebihan mengoptimasi akurasi sehingga diusulkan digunakan sebagai metode optimasi untuk memprediksi harga saham. Adanya prediksi harga saham dengan bantuan metode B WEMA dengan Optimasi LM dapat meningkatkan akurasi prediksi harga saham dibandingkan B-WEMA tanpa optimasi, sehingga mengurangi risiko trading dan meningkatkan persentase keberhasilan. Hasil menunjukkan selisih antara harga nyata dengan prediksi minimum sebesar 4,03%, error terkecil dari MSE sebesar 719,56, dan MAPE sebesar 1,99%.

Published: March 2021

Kenaikan jumlah penyandang autisme di Indonesia diikuti dengan bertambahnya kebutuhan terhadap pengajar. Permasalahan utama terkait pengajar anak dengan autisme adalah kurangnya keterampilan pengajar dalam menangani anak dengan autisme. Salah satu metode yang digunakan calon pengajar anak dengan autisme untuk meningkatkan keterampilan mengajarnya adalah dengan memainkan drama bertukar peran. Satu orang berperan sebagai guru, sedangkan yang lain berperan sebagai anak dengan autisme. Dari wawancara yang dilakukan terhadap beberapa mahasiswa pendidikan khusus autis, metode tersebut dinilai kurang efektif untuk memahami dan merespons perilaku anak dengan autisme. Dewasa ini, Virtual Reality (VR) memungkinkan calon pengajar berlatih meningkatkan kemampuan mengajarnya pada lingkungan yang lebih aman. Umumnya, proses simulasi pembelajaran menggunakan VR memanfaatkan manusia virtual yang memiliki fitur maupun kemampuan spesifik. Makalah ini menyajikan penggunaan model ADDIE untuk mengembangkan animasi manusia virtual yang dapat digunakan sebagai agen pembelajaran bagi calon pengajar anak dengan autisme. Animasi tersebut merupakan representasi gerakan yang sering dilakukan oleh anak dengan autisme yang dapat digunakan sebagai modul pada VR. Dari hasil pengujian yang dilakukan, diketahui bahwa animasi yang dikembangkan dianggap sudah dapat merepresentasikan perilaku anak dengan autisme.

Published: March 2021

As a result of the researches, it has been revealed that heart attack is the number one cause of death in the world. This problem will continue to increase, especially today and in the future. In this study, a heart attack was predicted by considering the factors affecting heart attack. Due to the uncertain conditions in heart attack, the fuzzy logic method, which is frequently used in healthcare, was used and expert opinions were taken into account in the model created. 576 rules were defined using the Mamdani fuzzy inference method. The study was tested with 10 patient data and the results were compared with the actual values. In addition, multiple regression analysis was performed, variables that had a significant effect on heart attack were determined, and the relationship between dependent and independent variables was examined. It was shown in the study that dependent variables explained the independent variable by 41.9% thanks to the multiple regression analysis. The regression equation obtained in line with these results significantly predicted the heart attack and the effect levels of the independent variables were determined.
Modelo para aplicação do direito à educação superior privada no brasil: policontexturalidade em Gunther Teubner
Authors: Andrade Ruy Amaral
Published: March 2021

Tornou-se cada vez mais frequente a propositura de ações judiciais que tem por objeto o acesso ao

ensino superior privado em Direito de jovens que não cumprem os requisitos necessários apontados

no artigo 44, inciso II, da Lei de Diretrizes e Bases da Educação (Lei 9.304 de 1996), em especial, a

conclusão do ensino médio. O que se propõe no presente trabalho é a análise da aplicação do direito

que rege as relações jurídicas das instituições privadas de ensino superior, aplicação que faz parte

do contexto dessas relações, qual seja, o acesso ao ensino superior privado e a judicialização desse

acesso. Para tanto, será proposta a adoção do modelo teórico apresentado por Gunther Teubner,

que preconiza reconstruir a compreensão da regulamentação jurídica da matéria, a respeito da

convivência entre o Direito Público e o Direito Privado, adotando, como alternativa, o conceito de

policontexturalidade, cunhado pelo filósofo alemão Gotthard Günther. Propõe-se que o Direito

Educacional, em especial no ensino superior, seja visto como sistema autônomo, compatível com o

Direito Privado, de modo que eventual julgamento sobre o mérito da questão esteja de acordo com a

matriz institucional desse sistema.

A problemática jurídica da aquisição de terras brasileiras por estrangeiros
Authors: Andrade Rodrigo Freitas
Published: March 2021

Este artigo propõe identificar, por meio da revisão qualitativa de literatura acadêmica, técnica e jurídica, as limitações à aquisição de terras no Brasil, impostas aos estrangeiros pelo ordenamento jurídico pátrio, sob o prisma do Direito Constitucional, do Direito Civil e do Direito Agrário. Os investimentos internacionais em atividades que demandam o uso de terras têm ocorrido de maneira módica e limitada em razão da insegurança jurídica perpetrada pelo atual regramento nacional, em especial pela interpretação normativa da Advocacia-Geral da União (AGU) sobre a Lei 5.709/71, reguladora da aquisição de imóveis rurais por estrangeiros. Dentre os principais diplomas, serão abordados a Lei 5.709/71; a Constituição da República de 1988 (CF); a Emenda Constitucional 6/95, que revogou o art. 171; o Parecer GQ-22/94 da AGU, que concluiu pela recepção da Lei 5.709, ressalvado o § 1º do art. 1º; o Parecer GQ-181/98 da AGU, que reexamina o Parecer AGU/LA-04/94; o Parecer CGU/AGU 01/2008-RVJ, que conclui pela recepção da Lei 5.709/71 como um todo, tanto pela CF/88 (redação originária), quanto pela EC 6/95; e a Instrução Normativa 88/17 do Incra, que regula a aquisição e o arrendamento de imóvel rural por pessoa natural estrangeira residente no País, por pessoa jurídica estrangeira autorizada a funcionar no Brasil e por pessoa jurídica brasileira equiparada à estrangeira, além de dar outras providências. São apontadas diversas barreiras, impostas pela legislação e por normas infralegais, a forâneos que desejam comprar imóveis rurais. Percebe-se, também, que as medidas limitadoras variam de acordo com o contexto político-social, momento no qual são criadas regras e proferidas interpretações mais ou menos restritivas.
Metáfora conceptual en el discurso matemático de algunos profesores en el Eje Cafetero

Published: March 2021

Hay algo en el lenguaje de las matemáticas más allá de los meros signos y símbolos, de sus significados planos y simples, de ser herramientas aplicadas en áreas como las ingenierías, u otras ciencias como la Biología, la Química o la Física. Algo en sí, un tanto interesante, pues cada una de ellas tiene sus propios intereses y son el resultado de formas de ver el mundo en el cual el ser humano está inmerso. Un algo más allá de lo utilitario; una presencia que toca y oprime el corazón; aquello escondido en los laberintos de lo poético; algo por que tal vez, muchos quieren creer en la matemática en singular y no como un elemento creado, sino como habitante de un mundo ideal por descubrir. Es algo oculto, presentido también por los matemáticos, y que solo se revela a quienes tengan la humildad de admitir que este tipo de pensamiento no es exclusivo de una élite, sino algo susurrado por las voces del silencio y de las plantas. Algo misterioso y profundo en los ojos de un león al mirar en ...

An artificial neural network-based prediction model for utilization of coal ash in production of fired clay bricks: A review
Authors: Vidak-Vasic Milica , Pezo Lato , Gupta Vivek , Chaudhary Sandeep , Radojevic Zagorka
Published: March 2021

This study analyzed the last 20 years` data available on power plant coal
ashes used in clay brick production. The statistical analysis has been
carried out for a total of 302 cases based on the relevant parameters
reported in the literature. The chemical composition of the clays and coal
ashes, percentage incorporation and maximum particle size of ash, size of
fired samples, peak firing temperature, and the corresponding soaking time
were selected as inputs for modeling. The product characteristics i.e. open
porosity, water absorption, and compressive strength was taken as output
parameters. An artificial neural network model has been developed and showed
a satisfactory fit to experimental data and predicted the observed output
variables with the overall coefficient of determination (r2) of 0.972 during
the training period. Besides, the reduced chi-square, mean bias error, root
mean square error, and mean percentage error were utilized to check the
correctness of the obtained model, which proved the network generalization
capability. The sensitivity analysis of the model suggested that the
quantity of Na2O coming from brick clays, the percentages of SiO2 and K2O
coming from ashes, and MgO coming from clays were the most influential
parameters in descending order for the ash-clay composite bricks` quality,
mostly owing to the influence of fluxes during firing.

Published: March 2021

Adsorption of anthraquinone dye Acid Blue 111 by alumina-iron oxide doped
particles prepared by sol-gel method from aqueous solutions was studied. The
adsorbent morphology was revealed by FESEM and the crystallographic phase is
analyzed by the XRD technique. The effect of adsorbate and adsorbent
concentrations, pH value, type of adsorbent and thermodynamic parameters on
dye removal by adsorption was studied. The change of dye concentration
during the adsorbtion was followed using the UV-Visible spectrophotometer.
The change of the adsorbent surface before and after dye removal was
observed using the Fourier Transformation-infrared spectroscopy (FT-IR). The
adsorption kinetics is in accordance with the pseudo-second-order kinetics
model. The Langmuir and Freundlich adsorption isotherm models were used to
describe the adsorption process. The thermodynamic study of dye adsorption
proves the process is spontaneous with exothermic nature.

Published: March 2021

Aile işletmelerinde nepotizm uygulamaları üzerine yapılan çalışmalar, genellikle nepotizmin çalışanlar üzerindeki etkilerini incelemeye yöneliktir. Oysaki uygulamada nepotizmin büyük ve başarılı aile işletmeleri tarafından bir yönetim stratejisi olarak -özellikle devir sürecinde- etkili şekilde uygulandığı göze çarpmaktadır. Bu çalışma, stratejik yönetim bakış açısı ile küçük ve orta büyüklükteki aile işletmelerinin devamlılığında planlı nepotizmin nasıl bir etkisinin olduğunu ele almaktadır. Bu amaçla, 13 aile işletmesi mensubundan yarı-yapılandırılmış görüşme tekniği ile veri toplanmıştır. Veriler, içerik analizi yapılarak incelenmiştir. Araştırmanın bulguları, (a) nepotizme yönelik tutum, (b) planlı nepotizm uygulamaları, (c) aile işletmesinin devri ve nepotizm, olmak üzere dört ana tema etrafında sunulmuştur. Araştırmanın sonucunda, kurucularda planlı nepotizm uygulamaya dönük istek olduğu, ancak nepotlarda bu isteğin bulunmadığı tespit edilmiştir. Bu durum, aile işletmelerinin devamlılığı açısından önemli bir sorun oluşturmaktadır. Ayrıca, araştırma sonuçları nepotizmin küçük ve orta büyüklükteki aile işletmelerinde farklılaştığını göstermektedir. İşletmede çalışan sayısı artıkça ve kurucu tarafından işletmeye verilen emek arttıkça, planlı nepotizmine yönelik faaliyetler de artmaktadır. Araştırma bulguları literatürdeki teorik bulgular ekseninde tartışılarak yorumlanmıştır.

Critiquing ‘islandness’ as immunity to COVID-19: A case exploration of the Grenada, Carriacou and Petite Martinique archipelago in the Caribbean region
Authors: Telesford John N.
Published: March 2021

Can mitigation of the spread and transmission of COVID-19 cases on islands, especially in the Caribbean, be attributed to the fact that they are just that: islands? As the corona crisis escalated in 2020, island authorities initially were able to keep COVID-19 cases low and mitigate their spread by implementing unprecedented actions, foremost among them border closures. However, as the realities of economic stresses surfaced, due to the decline in tourism, especially in the Caribbean, the need to balance COVID-19 spread and economic propriety posed a challenge. In this regard, the corona crisis illuminated spatial notions of islandness: boundedness, smallness, isolation and fragmentation. This perspective essay explores islandness in the context of the actions taken in the case study tri-island state of Grenada, Carriacou and Petite Martinique. Being a tri-island state, the nuances of islandness, experienced in an archipelagic context (an archipelago within the Caribbean archipelago) are emphasized. The paper chronicles the measures, issues and challenges of the case islands during the period between 13 March 2020 and 30 January 2021 and juxtaposes them against other actions in other countries and theories of islandness. It is hoped that this paper will contribute to and champion the field of island studies, especially within the Caribbean region.
Glimpse of interaction between traditional and digital banking instruments
Authors: Avis Oleg Usherovich , Kosarev Vladimir E.
Published: March 2021

The article is focused on studying the global trends in banking systems: development of digital banking, displacement of traditional banking - banking of branches (affiliates). Within the framework of this global trend, a hybrid banking service model is noticed to be forming, where traditional and digital banking systems complement each other. The concepts of traditional and digital banking are given a detailed consideration. The element of traditional banking – a “live” dialogue between a client and a bank employee - is a very important aspect for the efficient customer service and banking system on the whole. The models of the banking system of modern Russia, Germany, Switzerland and other countries of continental Europe are largely homogeneous. The interaction of traditional and digital banking instruments develops according to the general principles. There has been analyzed the research of the German economists and bankers. There has been mentioned the successful operation of banks in Switzerland, Germany and other banks using the banking systems of the continental model for building new cooperatives of banking instruments. A special importance is given to another global trend - the creation of financial and banking ecosystems, which today mean the combination of banking and non-banking services in the interests of developing a client-oriented approach. There has been justified the hypothesis of the inevitability of building a hybrid model of traditional and digital banking, its actual implementation into actively developing financial and banking ecosystems.
Theoretical and practical aspects of spatial and industrial development of region in terms of digitalization
Authors: Urasova Anna A. , Balandin Dmitriy A.
Published: March 2021

The article considers the problems of spatial development of Russian regions in the digital era. Based on the comprehension of modern scientific and theoretical views on the application of the spatial approach in foreign and domestic practice of regional management and the results of using the methods of strategic and factor analysis, a high level of subjectivity was revealed in determining the priorities of territorial development, ignoring specific features and significant industry factors economic growth. A new formulation of the economic category “spatial and sectoral development of the region” is proposed, which allows concretizing the general distinctive features of the development of the subjects of the Russian Federation. The priority directions of the spatial and sectoral development of the RF regions have been clarified on the basis of an analysis of a wide range of factors that determine existing and new problems in terms of territorial and sectoral criteria. There have been considered the factors impeding building up competitive advantages in the sectoral section of the regional economy, including making decisions on optimizing various kinds of costs for scenario options for their elimination; to intensify an adaptive response to the need to develop targeted strategic documents focused on the creation of innovative industries, the introduction of digital technologies and competencies that contribute to the production of high-tech competitive products in the context of active digitalization of society.

The article considers the monetary policy as a special prevailing type of state economic policy in the modern system of economic knowledge based on using a wide range of instruments for regulating the volume of money supply, rate of money circulation and cash flows. According to the main directions of the unified state monetary policy for 2019 and a period of 2020-2021, a consistent monetary policy aimed at maintaining low rates of price growth increases the predictability of economic conditions, allows for more confident production, investment plans and long-term savings. Only if price stability is maintained it is possible to achieve the targets of the main macroeconomic factors of the state. It is inflation that is an essential factor in ensuring macroeconomic and economic stability. The main reasons for inflation are listed: decreasing GDP while maintaining the volume of money in circulation, increased government spending due to emission and excess over income, monopoly in the economy, some political processes, foreign economic sanctions against commercial and state companies, etc. There has been studied the influence of theoretical aspects of inflationary and price security in the context of using modern instruments of the state's monetary policy. The work of both Russian and foreign specialists in the field of economic security of the state has been analyzed, as well as materials from periodicals by leading economists. The main research methods used in writing the work were general scientific methods of induction and deduction, the method of theoretical systems analysis, and the monographic (descriptive) method.

Для регулирования вариатропной структуры центрифугированных изделий авторы данной статьи совместили процесс центрифугирования с вибрированием. Во время эксперимента вибрации формы обеспечивались за счет надетых на валы установки хомутов. Представлена авторская экспериментальная установка для создания виброцентрифугированных образцов кольцевого сечения с вариатропной структурой, а также способ их изготовления. Выделены технологические параметры вибрирования, которые оказывали наиболее значимое влияние на характеристики виброцентрифугированного бетона, конструкций и изделий из него. В опытах варьировались высота технологических выступов хомутов и шаг между ними. Исследовалось влияние этих факторов на физико-механические характеристики бетона: плотность; кубиковая прочность на сжатие; призменная прочность на сжатие; прочность на растяжение при изгибе; прочность на осевое растяжение. Приведен анализ результатов экспериментальных исследований и получены следующие физико-механические характеристики виброцентрифугированных бетонов, изготовленных с использованием хомутов: лучшие – с высотой технологических выступов 5 мм и шагом между ними 30 мм, самый низкий показатель – соответственно 2,5 мм при любом шаге.

To regulate the variatropic structure of centrifuged products, the authors of this article combined the
process of centrifugation with vibration. During the experiment, vibrations of the mold were provided with
clamps set on the shafts of the installation. The author's experimental setup for creating vibrocentrifuged samples of annular cross-section with a variatropic structure, as well as a method for their manufacture is presented.
The technological parameters of vibration, which had the most significant effect on the characteristics of vibrocentrifuged concrete, structures and products made of it, were identified. In the experiments, the height of
the technological protrusions of the clamps and the pitch between them were varied. The influence of these
factors on the physical and mechanical characteristics of concrete was investigated: density; cube compressive
strength; prismatic compressive strength; bending tensile strength; axial tensile strength. Analysis of the results
of experimental studies is given and the following physical and mechanical characteristics of vibrocentrifuged
concretes made using clamps have been obtained: the best ones with a height of technological protrusions of

The production of porous scaffolds has been widely investigated by the scientific community due to its suitability for tissue engineering. Among techniques that allow the fabrication of porous materials, electrospinning is appealing for being robust and versatile. This research investigated the pore formation in poly (L-co-D,L lactic acid) fibers obtained by conventional electrospinning and the influence of chloroform as a single solvent on fiber morphology. Random and highly porous fibers with a mean diameter of 2.373 ± 0.564 µm were collected. Chloroform affects the fiber morphology, mainly for its fast evaporation and low density of charges. The solvent on the surface evaporates quickly, and the low stretch of the jet does not help the polymer to reorganize over the length of the fiber, forming pores. In conclusion, the low dielectric constant and boiling point of chloroform induce pores formation along the PLDLA fibers.
Sign Language Recognition using Principal Component Analysis and Support Vector Machine

The World Health Organization (WHO) estimates that over five percent of the world's population are hearing-impaired. One of the communication problems that often arise between deaf or speech impaired with normal people is the low level of knowledge and understanding of the deaf or speech impaired's normal sign language in their daily communication. To overcome this problem, we build a sign language recognition system, especially for the Indonesian language. The sign language system for Bahasa Indonesia, called Bisindo, is unique from the others. Our work utilizes two image processing algorithms for the pre-processing, namely the grayscale conversion and the histogram equalization. Subsequently, the principal component analysis (PCA) is employed for dimensional reduction and feature extraction. Finally, the support vector machine (SVM) is applied as the classifier. Results indicate that the use of the histogram equalization significantly enhances the accuracy of the recognition. Comprehensive experiments by applying different random seeds for testing data confirm that our method achieves 76.8% accuracy. Accordingly, a more robust method is still open to enhance the accuracy in sign language recognition.
