Authors: Cahya Reiza Adi , Bachtiar Fitra A. , Mahmudy Wayan Firdaus
Published: April 2021

The wealth of opinions expressed by users on micro-blogging sites can be beneficial for product manufacturers of service providers, as they can gain insights about certain aspects of their products or services. The most common approach for analyzing text opinion is using machine learning. However. opinion data are often imbalanced, e.g. the number of positive sentiments heavily outnumbered the negative sentiments. Ensemble technique, which combines multiple classification algorithms to make decisions, can be used to tackle imbalanced data to learn from multiple balanced datasets. The decision of ensemble is obtained by combining the decisions of individual classifiers using a certain rule. Therefore, rule selection is an important factor in ensemble design. This research aims to investigate the best decision combination rule for imbalanced text data. Multinomial NaÃ¯ve Bayes, Complement NaÃ¯ve Bayes, Support Vector Machine, and Softmax Regression are used for base classifiers, and max, min, product, sum, vote, and meta-classifier rules are considered for decision combination. The experiment is done on several Twitter datasets. From the experimental results, it is found that the Softmax Regression ensemble with meta-classifier combination rule performs the best in all except in one dataset. However, it is also found that the training of the Softmax Regression ensemble requires intensive computational resources.
Initial Suspicion on Detecting Code Plagiarism and Collusion in Academia: Case Study of Algorithm and Data Structure Courses

Published: April 2021

In engineering education, some assessments require the students to submit program code, and since that code might be a result of plagiarism or collusion, a similarity detection tool is often used to filter excessively similar programs. To improve the scalability of such a tool, it is suggested to initially suspect some programs and only compare those programs to others (instead of exhaustively compare all programs one another). This paper compares the ef-fectiveness of two common techniques to raise such initial suspicion: focusing on the submissions of smart students (as they are likely to be copied), or the submissions of slow-paced students (since those students are likely to breach academic integrity to get higher assessment mark). Our study shows that the latter statistically outperforms the former by 13% in terms of precision; slow-paced students are likely to be the perpetrators, but they fail to get the submissions of smart students.

Authors: Kriswibowo Rony , Ramdani Fatwa , Aknuranda Ismiarta
Published: April 2021

Disaster management is important to reduce the risk casualties as well as the environment and economic impacts. One of the stakeholders in disaster management in Indonesia at the local level is the Regional Disaster Management Agency (Badan Pengelolaan Bencana Daerah â€“ BPBD).Â  In the process of disaster management, there are several phases. Thi initial phase is known as the prevention phase, which is an attempt to eliminate or reduce the possibility of a threat. In this phase, the role of information technology is important to increase the efficiency in disaster management. One of the information technologies that is used widely in disaster management is the Geographic Information System (GIS). This study explores the role of GIS technology employed at BPBD of Batu City in disaster management. The Research Qualitative Data Analysis (RQDA) method is employed based on the questionnaire data. The results show that the role of GIS technology is very limited. The disaster management at the Batu City is mostly done by the traditional method with the manual approach. The role of technology is limited it needs to be improved. Suggestions for increasing the role of technology is to conduct training on the use of GIS for employees. It is expected to increase the role of technology in disaster management.

(REPRINT) - BODYING THE JOURNALIST
Authors: Francoeur Chantal
Published: April 2021

ABSTRACT – This article lays out a theoretical framework through which the journalist’s body is rendered both visible and accountable. Drawing on ethnographic and geographic scholarship, it argues that the journalist’s body serves as a sensor, as a transducer (Helmreich, 2007), and as a depository. Conceiving the journalist’s body as an instrument that simultaneously senses, transforms, and stores information opens the door to a rich and nuanced understanding of how sensing bodies participate in and contribute to the journalistic endeavor, both practically and epistemologically.RESUMO – Este artigo expõe um quadro teórico no qual o corpo jornalístico é apresentado de forma visível e explicável. Com base em um conhecimento etnográfico e geográfico, argumenta que o corpo jornalístico atua como um sensor, como um transdutor (Helmreich, 2007) e como um depositário. A concepção do corpo jornalístico como um instrumento que simultaneamente sente, transforma e armazena a informação abre espaço para uma compreensão rica e nuançada de como o corpo sensitório participa e contribui para o esforço jornalístico, tanto do ponto de vista prático como epistemológico.RESUMEN – – Este artículo expone un marco teórico a través del cual el cuerpo del periodista es presentado de forma visible y relatable. Basándose en el conocimiento etnográfico y geográfico, sostiene que el cuerpo del periodista sirve como sensor, como transductor (Helmreich, 2007) y como depositario. Concebir el cuerpo del periodista como un instrumento que simultáneamente siente, transforma y almacena información abre la puerta a una comprensión rica y matizada de cómo los cuerpos sensoriales participan y contribuyen al esfuerzo periodístico, tanto práctica como epistemológicamente.

Objetivo: Analisar, por meio de uma revisão narrativa, o impacto do uso da Terapia hormonal (TH) na qualidade de vida de mulheres no climatério e como fator de risco para o desenvolvimento do câncer de mama, bem como discutir as opções terapêuticas existentes, levando em consideração a melhoria na qualidade de vida das pacientes. Revisão Bibliográfica: A menopausa caracteriza o fim do período reprodutivo da mulher, com diminuição da atividade folicular ovariana. Esse período é marcado por instabilidades hormonais e sintomatologia marcante que faz com que muitas mulheres procurem a TH como forma de tratamento. Entretanto, a TH pode acometer o tecido mamário e resultar em uma neoplasia, a depender da formulação e do tempo de uso, além de possíveis fatores de risco para câncer de mama. Considerações finais: Conclui-se que a terapia hormonal está associada ao aumento do risco de desenvolvimento do câncer de mama, sendo esse risco atribuído, principalmente, aos progestagênios medroxiprogesterona, noretisterona e levonorgestrel. A descontinuação do uso destes tende a diminuir os riscos e, de uma forma geral, a sua administração não é recomendada por período superior a cinco anos.

Culture: management and financing in the Russian digital reality
Authors: Kryshtanovskaya O. V. , Lavrov I. A. , Evsegneeva N. S.
Published: April 2021

The state, by virtue of its nature, is capable of controlling and regulating all spheres of society. The main instrument of this regulation is the ability to redistribute resources between different spheres of life. Russia, in the era of new global challenges in the conditions of fierce information competition, needs to pay special attention to the cultural sphere of society. It is the preservation and transmission of cultural values, norms and experience to new generations that are able to ensure the unity of multinational people in turbulent circumstances. However, due to numerous factors, the cultural sector, receives insufficient state support and funding. In modern realities, in addition to economic problems, the sphere of culture is experiencing new difficulties associated with the digitalization of society. The article presents the results of the research, in the course of which the all-Russian expert survey was conducted. The experts gave their opinions on the most urgent problems in the sphere of culture, which were subsequently analysed. The most acute issue, according to the majority of experts, is the underfunding of the cultural sphere, which leads to significant consequences: unequal participation of citizens in cultural life, use of cultural institutions, limited access to cultural values; personnel stagnation in this sphere. In addition, the sphere of culture is subject to the processes of politicization and commercialization, which slows down its development and reduces the overall level, which has a negative impact on society. Experts state that cultural reforms aimed at modernization and the revision of cultural policy are necessary in the sphere of culture. Such changes are possible only with the adoption of a new law “on culture”, which would renew public administration in this sphere and ensure the progressive and systematic growth of the cultural level of the population.
Culture as an attribute of digital transformation

Published: April 2021

The article comprehends the concept of digital culture that appeared with the beginning of the information/digital era at the end of the last century. The paper considers digital culture from the point of view of the general resource of the knowledge society and as a new social ecology that determines the experience and capabilities of people at the present time, when the digital network environment has brought new practices, opportunities and threats. Speaking about culture in the context of information and communication technologies, the authors emphasize that its influence is even more significant, since the way it is used can affect the change in the essence of our communication and cultural models and become a support for the digital transformation of organizations. Digital culture is understood as the way that society uses to receive and process information. It is required to comprehend and create a new digital culture as a guarantor of the implementation and adoption of changes in the context of widespread digitalization and rethinking of business processes, distribution channels and relations with consumers, leading, in turn, to a change in the value proposition and the consumer segments themselves. Based on the analysis, the authors formulate and substantiate five main reasons why building a digital culture should become a key problem for the successful development of any organization: 1) digital transformation will not be complete without the development of a thriving digital culture; 2) insufficient organizational culture is detrimental to success in the digital age; 3) a strong digital culture is a competitive advantage for an organization; 4) a strong digital culture is the key to business longevity; 5) using a digital culture can increase employee engagement in the work process.

EXPLORING RELATIONSHIP BETWEEN LOCAL DYNAMICS AND RELAXATION PROCESSES ON THE TERAHERTZ FREQUENCIES IN POLYMERS WITH HYDROGEN BONDS
Authors: Рыжов Валерий Александрович
Published: April 2021

На терагерцовых частотах либрационно-колебательное движение связано с диэлектрической релаксацией в неупорядоченных твердых телах с водородными связями. Взаимодействие между этими процессами ещё мало изучено, особенно при температурах ниже температуры стеклования, что особенно существенно для молекулярной подвижности в полимерах. Изучены полимеры с водородными связями (полиамид-6 и поливинилхлорид) при температурах от 90 до 4000К в диапазоне 0,25 - 4 ТГц с использованием дальней ИК-спектроскопии. Три общих особенностей наблюдались в спектре диэлектрических потерь, Ɛ"(ν):(а) при температурах значительно ниже стеклования (T) эти потери представлены низкочастотным крылом пика поглощения, обусловленного либрацией мономерных звеньев полимеров. (б) При 0.7 T < T < T наблюдаются дополнительные температурно-зависимые потери, которые могут быть связаны с проявлением вторичных релаксационных процессов. (с) При температурах выше T преобладающим вкладом в терагерцовые потери становятся первичные процессы α-релаксации. Полученные результаты показывают, что эволюция терагерцовых потерь с температурой вызвана изменением структуры водородных связей, которое, по-видимому, является универсальным для систем с подобными межмолекулярными взаимодействиями

At terahertz frequencies, torsional-vibrational motion is associated with dielectric relaxation in disordered solids with hydrogen bonds. The interaction between these processes has not been studied much, especially at temperatures below the glass transition temperature, which is especially important for molecular mobility in polymers. Polymers with hydrogen bonds (polyamide-6 and polyvinyl chloride) were studied at temperatures from 90 to 4000 K in the range 0.25 - 4 THz using far-infrared spectroscopy. Three common features were observed in the spectrum of dielectric losses, Ɛ"(ν):(А)at temperatures well below glass transition (T), these losses are represented by the low-frequency wing of the absorption peak due to libration of the monomer units of the polymers. (B) At 0.7 T < T < T , additional temperature-dependent losses are observed, which may be associated with the manifestation of secondary relaxation processes. (C) At temperatures above T, the primary relaxation processes become the dominant contribution to terahertz losses. The results show that the evolution of terahertz losses with temperature is caused by a change in the structure of hydrogen bonds, which, apparently, is universal for systems with similar intermolecular interactions.

Authors: ; Hartanto Budiyuwono Elva
Published: April 2021

Abstract- Visually impaired is a general term to describe the condition of a person experiencing disability to their sense of sight. Due to the disability, the process of orientation and mobility of the people with visually impairment is inhibited. Therefore they try to increase their sensitivity of other senses like sense of touch, sense of smell, and sense of hearing to obtain information from the surrounding physical environment. PSBN Wyata Guna is a residential for the visually impaired, as the physical environment it must have physical elements that can provide information which affect effectivelly to the orientation and mobility of the visually impaired. The purpose of this study is to find out what physical elements in the environment of PSBN Wyata Guna that affect the orientation and mobility of the visually impaired and how effective the influence of these elements.This study use qualitative descriptive methods by mapping the behavior of fourteen respondents (person-centered mapping) who do orientation and mobility in the physical environment of PSBN Wyata Guna. Physical environments are classified based on elements that define the space, ie horizontal and vertical planes, which is, tactile pavements, materials differences, Ramps, steps, corridor columns, ceramic walls, shrubs, and hand railling. Observations held on Saturday and Sunday in the morning-afternoon when most of visually impaired do their activities outside the dorm.The result of this research shows that  people with visual impairment in the environment of PSBN Wyata Guna use the physical environment to obtain information for their orientation and mobility. This orientation and mobility activity is mostly affected by tactile pavements, ceramic walls, and Ramps. Shrubs and hand railling have less role to the orientation and mobility of the visually impaired. Thus, it can be concluded that the physical environment of PSBN Wyata Guna is influential in the orientation and mobility of the visually impaired. Key Words: orientation and mobility, visually impaired, physical environments, physical elements, PSBN Wyata Guna
EFFECTS OF STREET FURNITURE TOWARDS THE LESSENING OF PEDESTRIAN AREA IN BRAGA STREET

Published: April 2021

Abstract- Bandung has revitalisation plans stretching throughout the city to promote “smart” and “sustainable” living. One of these projects falls on jl. Braga revitalisation project that has shown significant difference in outlook and in visitor count. The popularity of the street may in return cause discomfort for visitors, as the space allowance per person becomes smaller. This assumption has already been made by Carmona (2003) where he stated that “an unfriendly environment’s pedestrian flow may be increased significantly if the space becomes more pedestrian friendly”. The aim of this study is to evaluate the physical changes made by the revitalisation process in correlation to overcrowding. The discussion will begin by identifying elements withing the street that cause obstructions (obstacles), and a simulation of the circulation space acquired by the obstacle (or the activity it generates) is made in order to calculate the resultant circulation space and measure its overcrowding level. Overall, results show the overcrowding level of the street is constrained and congested. Witihin six out of seven obstructions analysed, it is proved that overcrowding is caused by the acquisition of space of obstacles, whether by itself or by the activities it generates.  Key Words: obstacle, obstruction, overcrowding, jl.

Abstrak- Agama Hindu Bali merupakan perkembangan dari agama Hindu India, pada awalnya diduga bahwa  semua ajaran agama Hindu bermula pada negara India dan menyebar ke dalam pulau Jawa terlebih dahulu  setelah itu ajaran Hindu India menyebar dan masuk ke dalam pulau Bali. Arsitektur Hindu India juga ikut masuk  bersamaan dengan ajaran Agama Hindu India, terdapat aturan – aturan yang harus di ikuti dalam merancang  sebuah bangunan, dan kuil termasuk salah satunya. Arsitektur Hindu Bali mendapatkan banyak pengaruh budaya  dari luar India dan Bali, seperti pengaruh dari Jawa dan Belanda yang membuat arsitektur Hindu Bali menjadi  seperti sekarang. Penelitian ini bersifat analisis kualitatif, dengan menggunakan metode analisis deskriptif dan komparatif.  Penelitian dilakukan pada 23 Juni 2019 telah dilakukan survey lapangan Kuil Meenakshi Amman di India dengan  mendatangi objek – objek penelitian secara langsung dan melakukan wawancara kepada ahli – ahli di India.  Sedangkan waktu penelitian objek di Indonesia yaitu Pura Besakih di Bali, telah dilakukan pada tanggal 31 Juli  2019 dengan cara mendatangi objek penelitian dan mewawancarai ahli yang berada di objek penelitian. Dalam ajaran agama Hindu India dan Hindu Bali terdapat pembagian tiga dunia, yaitu dunia bawah,  dunia tengah, dan dunia atas. Ketiga bagian dunia ini dipresentasikan pada gubahan bangunan kuil dan pura.  Pada Kuil India gubahan bangunan tentang dunia bawah, tengah, dan atas dibagi menjadi tujuh bagian.  Sedangkan di Bali persis dibagi menjadi tiga bagian yaitu dunia atas (utama), dunia tengah (madya), dan dunia  bawah (nista). Selain itu pada penggunaan ornamen terdapat perbedaan pada detail sosok dan ornamen.  Penelitian ini mengomparasikan tata massa, tata ruang, sosok, dan ornamen pada kuil Meenakshi dan pura  Penataran Agung Besakih dan dilihat persamaan dan perbedaan yang dimilikinya. Dengan adanya  perkembangan kepercayaan agama Hindu , baik dari cara sembahyang maupun perspektif sosial pemaknaan  terhadap tata massa, tata ruang, sosok, dan ornamen yang diturunkan / diwariskan oleh ajaran Hindu India  dalam merancang kuil ikut berkembang dan memiliki detail yang berbeda dengan kuil Hindu di India sendiri.

Our previous study demonstrated that the blue butterfly pea flower (Clitoria ternatea)
had several pharmacological effects to treat inflammatory-related diseases, including
edema and diabetes. However, its benefit for preventing dental caries and protecting
the tooth has not been explored yet. Here, we investigated whether C. ternatea
ethanolic extract (CTEE) prevented dental caries through antibacterial and antiquorum
sensing activities toward oral pathogen Streptococcus mutans in vitro. CTEE was
made by using kinetic maceration in ethanol. Antibacterial activity of CTEE against S.
mutans was tested using disk diffusion agar and microdilution assays. Quorum sensing
system employed Chromobacterium violaceum bacteria to produce violacein, and
CTEE at various concentrations was tested for its antiquorum sensing activity to
inhibit the violacein production. Our results demonstrated that CTEE at 1 mg/mL
showed a significant inhibition >90% against S. mutans, indicating its MIC value. For
the quorum sensing system, CTEE at the lowest concentration (0.25 mg/mL)
significantly inhibit up to 68% of violacein produced by C. violaceum. These data
indicate that CTEE may act as a natural oral functional food with antibacterial and
antiquorum sensing activities for the prevention of dental caries.

Vinegar is regarded as a fine example of a traditional food that has several medicinal
values. It is used as a home-remedy for the management of diabetes and obesity. We
investigated how selected vinegar inhibit the digestive enzymes involved in carbohydrate
and lipid metabolism. A total of seven types of vinegar were examined as follows: apple
cider (ACV), balsamic (BV), brown rice (BRV), distilled white (DWV), malt (MV), nipah
palm (NPV), and red wine (RWV) vinegar. In vitro enzyme inhibition tests were
performed using α-amylase and lipase from porcine pancreas, and α-glucosidase from
Saccharomyces cerevisiae. In the α-amylase assay, NPV (IC50 = 60.97±1.71 mg/mL)
exhibited the strongest inhibitory effect, while RWV (IC50 =786.7±0.96 mg/mL) showed
the lowest inhibitory effect. RWV (IC50 =92.49±1.51 mg/mL), by contrast, had the highest
inhibitory effect against α-glucosidase and was followed by NPV (IC50 = 227.5±1.06 mg/
mL) and BRV (IC50 = 565.1±2.65 mg/mL). All of the samples showed potent inhibitory
effects against pancreatic lipase, with MV having the strongest and ACV the lowest
effects, respectively. IC50 values ranged from 48.45 mg/mL to 399.8 mg/mL. A
concentration-dependent inhibitory effect was recorded for each of the vinegar against all
three tested enzymes. None of the vinegar, however, exceeded the effects recorded for the
standard drugs. Interestingly, a weak correlation was found between total acidity and
enzyme inhibition, which asserted the presence of bioactive compounds in the vinegar. As
a conclusion, vinegar can be incorporated into the diet to lower the meal’s glycaemic
index and benefit those at risk of diabetes as well as diabetics.
Food security: state Financial support Measures for sustainable Development of Agriculture in Russian Regions

In the context of global economic instability, the problem of ensuring food security and sustainable development of agriculture at the international, national and regional levels becomes urgent. Existing methods for assessing the state of food security and sustainable development of agriculture, as a rule, have two main drawbacks: first, they are often static, and second, they include a scattered list of indicators that are difficult to systematically interpret in the analysis. Therefore, theaimof the study is to develop an adequate methodology for assessing the food security of the constituent entities of the Russian Federation. The construction of a thematic index is carried out in three stages: 1) a system of indicators is formed; 2) the values of indicators are normalized; and 3) sub-indices are calculated. The analysis of domestic and foreign literature on food security provided themethodological basisof the study. The system of indicators was clarified, which were combined into three groups (numerical indicators of the sphere of production, distribution, consumption, and food). The authors extended the retrospective assessment of food security at the meso-level by ranking and clustering Russian regions using hierarchical analysis and a new data filtering algorithm. The hierarchical procedure is based on a system of mathematical filtering of data, which is fundamentally different from existing methods for analyzing hierarchies. The authors replaced the fuzzy “what if” logic with a clear subordination of ranked indicators (subindices). The group of leaders was selected considering the accepted priority of indicators, the rest of the regions were united into a new subgroup, among which leaders and outsiders were singled out. At each new stage, new groups are ranked after excluding leaders and outsiders, they are in the “center of the circular convolution of data”, the procedure for stopping the procedure is the presence of two groups. This is a fundamental feature, scientific novelty, and value of the mathematical apparatus for multidimensional ranking of Russian regions in terms of food security. The authorsconcludedthat in modern Russia the problem of food security has not yet been resolved due to the insufficient use of general economic and special levers to increase the stability of the food system. The results of the study can be applied in the process of updating the state policy in the field of ensuring the sustainability of food systems at the macroand meso-level of management.
The Influence of Internal Contradictions in the Us Economy on Global Financialization and the Expansion of Fictitious Capital
Authors: Dinets D. A. , Kamaev R. A.
Published: April 2021

The financialization genesis of the global economy centered in the United States is on the bifurcation point now— a fictive capital’ expansion is damaging with the social capital regeneration mechanism disaster. The method of identifying and estimating the fictive capital’ extension is absent for now. The fictive capital exists as a metaphor on the science papers but not as an institutional basis of the capital flows directions. The paper aims to update the configuration of the global financial system, its dependence on the performance of US corporations and banks; to identify the sources of vulnerability of world finance and global liquidity from the fictitious capital of American financial markets. The methodology is theoretical pattern’ of financial capital movements and its real statistical market indicators comparison. The empirical base is statistical data about the financial flows and financial results especially about the US as a global financial center. Based on the results the authors have revealed an origin of fictive capital on the US bank sector by the justification for the conclusion of liquidity above the profitable as the purpose of financial operations. This conclusion is confirmed with the scale of off-balance sheet transactions of banks. Besides the regression between the prices of derivative’ basis assets and stock indexes has been shown. Also, the market capitalization of American companies is not sensitive to change in market liquidity indicators. The authors concluded that global financialization is supported by significant internal contradictions in the US economy. The source of contradictions is the financial mechanism for withdrawing liquidity from the sphere of production and circulation into the sphere of financial markets. Capital investment using instruments of the US financial market entails the threat of losing their liquidity. Forecasting the dynamics of the global economy without taking into account the role of fictitious capital, which is emerging in the American financial markets, leads to global vulnerability and may cause the next financial crisis.
