A Comparative Study of RSA and ELGAMAL Cryptosystems
Authors: Arhin Jnr Paul K , Asante Michael , Otoo Linda
Published: May 2023

Purpose: In this research, a comparative analysis of the RSA and ELGAMAL algorithms is presented using their encryption and decryption speed with different key sizes. ElGamal and RSA are two popular public-key cryptographic algorithms that depend on the mathematical difficulty of computing discrete logarithms in finite fields and factoring large integers, respectively.

Methodology: In this study, the speed at which messages of various sizes can be encrypted and decrypted using various key sizes is used to gauge how well these algorithms work.

Findings: RSA usually outperforms ElGamal in terms of encryption and decryption speed, according to the results. However, as the key sizes grow, the performance gap between the two algorithms narrows.

Unique Contribution to Theory, Policy and Practice: These findings can aid in selecting the appropriate algorithm and key size for different applications that require secure communication and data encryption.

Cosmopoéticas do refúgio: a resistência em tempos de capitalismo mundial integrado
Authors: Rocha Marcos Catelli
Published: May 2023

A obra discute as possibilidades de refúgio na atual sociedade de controle, utilizando o conceito de marronagem para caracterizar todo o processo histórico, cultural e político de aglutinação de forças de subalternos e subalternas, conjurando uma matriz de formas de vida inauditas que remetem a uma cosmopoética. Onde ocorre a produção de mundos, a criação de um fora da sociedade escravagista e posteriormente das outras formas de captura, as quais possuem valor de refúgio e de utopia concreta para todos que ainda permanecem cativos. A arte da fuga, que a experiência histórica da marronagem representa, se constitui como uma das modalidades, uma subversão a partir de dentro, seja esse dentro a colônia ou nossa sociedade de controle. Nesses tempos sombrios em que proliferam os mecanismos de controle, as resistências devem ser furtivas, mais do que frontais, evitando a exposição e a captura. A marronagem, significa menos uma forma de conquista do que de subtração ao poder e a cosmopoética não é um fetiche, ou uma marca registrada, apenas um termo, um modo entre outros de apontar para uma outra relação com o mundo que privilegie a escuta, mais do que a visão.

Authors: O. E. Mafimisebi , T. P. Akinbobola , T. E. Awoyomi
Published: May 2023

Value addition in agriculture remains an icing on the cake, and a sustainable pathway to economic growth and investment. However, in the quest to add value to agricultural produce, profitability is a great criterion to the choice and preference of various value additions. This study compared the profitability of value-added cassava products in Ondo state, Southwest Nigeria. Multistage sampling procedure was used to select 110 respondents. Primary data were collected and analyzed using both descriptive and inferential statistic (Profitability/Budgetary analysis and ANOVA). The results revealed that cassava roasted granules, Fufu and cassava flour were the common cassava value addition. Results of the profitability analysis revealed that processing cassava to pupuru (GM = ₦11,520) and cassava flour (GM = ₦10,860) were the most profitable cassava value addition. Lack of adequate technologies (x̅ = 0.96) and poor extension services (x̅ =0.93) were the major constraint to cassava value addition. Also, there was no significant differences (F = 3.107, ρ≥0.05) in the profits from the value-added products across the communities. The study therefore concluded that value addition is profitable in cassava, hence concerted efforts should be made by stakeholders in encouraging and enhancing value addition policies for agricultural produce especially cassava.
The Indigenous Struggle against ‘New’ Extractivism in the Peruvian Amazon
Authors: Jurema Bernardo , Oliveira Maria Cecilia
Published: May 2023

At the root of much of the deforestation, land rights violations, human rights abuses and ultimately the continuation of unequal, neocolonial North-South relations are the two-fold phenomena of global market pressures for extractivism and mass production of resources and the militarization of response to social conflicts created by these activities. We will investigate the ‘new’ extractivism economic activities from the perspective of the violence perpetrated by assemblages of power against indigenous protest movements in the Peruvian Amazon region. Specifically, we will probe a grassroots’ response to the way Peru’s elites have integrated the country within the global economic system: we focus on Indigenous peoples’ protests in 2008-9 against the new regulation to open the Amazon for development of resources by private companies carried out by Peru’s President Alan García, on the grounds that it represented a threat to their natural resources and livelihood.

Background: Having a beautiful body is a teenage woman’s dream, but those who are overweight have difficulty losing weight because of an imbalance between energy intake and energy use. To prove that aerobics in water is better than aerobics on the land to lose weight teenage women.

Methods: We included overweight teenage overweight women. The research design used randomized pre and post-test designs. The research subjects were 22 overweight teenage women 18 – 21 years old and divided into two groups. Subjects get treatment three times a week for eight weeks. The first group received aerobics in water, and the second group received aerobics on land. The body weight measurement using Camry scales.

Result: Based on the resulting test for aerobic in water, the p= 0.01, and the result for aerobic in land p= 0.624. Aerobic in water values with p<0.05, which states that aerobic in water has a significant effect on weight loss. However, aerobics on land results in a p> 0.05, meaning that it is not significant for weight loss.

Conclusion: Aerobic in water is more effective than aerobic on the land to lose weight for teenage women.
Brace and core stabilization to decrease vertebral curve in scoliosis cases scoliometer parameter and taps: a case study
Authors: Saputra Andrew Wijaya , Meir Ruth Golda , Pahlawi Riza
Published: May 2023

Introduction: Scoliosis is a disorder characterized by lateral curvature and rotation of the spine. The initial phase begins with a triggering event during the growth period. Characteristics that can be seen in scoliosis patients are differences in posture on the right and left sides, the rotation of the spine, the presence of hump, and other complications, namely pain and tightness.

Methods: This study was a case study with a brace method accompanied by CSE, which was carried out for approximately three months with an intensity of exercise 2 times a week and a home exercise program. The modified Borg scale measures shortness of breath. Pain is calculated using a visual analog scale. While scoliosis disorders are measured using two tools, namely the scoliometer and the Trunk Appearance Perception Scale (TAPS).

Results: Using objective parameters, namely the scoliometer. The degree of a scoliosis curve decreases in the thoracic part, with the initial value at 10° to 7°. Then there is no significant reduction in the lumbar region, with the initial interpretation at 6° and back to 6°. The result obtained through TAPS is also a stagnant number which is interpreted as no change in numbers too large or small, which means that the patient does not feel any significant changes in posture after going through an exercise program.

Conclusions: It can be concluded that there was a change in the scoliosis curve of the thoracic part by giving a brace accompanied by core stability exercises. However, this technique was less effective in the lumbar area. Behind that, when viewed during activities, patients felt a decrease in the intensity of tightness and pain.

Immersive technologies and the practice of foreign language teaching for students of computer science specialities
Authors: Muraviova Olena , Arkhypova Viktoriia , Krupei Mykhailo
Published: May 2023

The problem of digital transformation, which arose as a result of global processes of forming a new type of society, is an integral part of professional development at the current stage of human development. This bright trend is also reflected in education, especially during the training of IT students, where old methods of work are no longer relevant, because they do not take into account the needs of today. The traditional didactic paradigm does not form an individual educational trajectory and does not develop the skills of international interaction of future specialists in the labor market. Using the example of an educational program for students of computer specialities, the article proves the effectiveness of digital bilingual education, which differs from traditional forms because its methodological schemes involve the use of a foreign language not only as a tool of the humanitarian cycle, but also as a means by which speciality subjects are taught. In order to develop immersion, that is, a type of digital bilingual education where a large number of subjects are studied in a foreign language, it is necessary to perform a complex task that requires colossal training at various levels – a sufficient informational and material university base and a powerful scientific and methodological potential among professors and teachers stuff. Learning conditions within bilingual programs are implemented mainly in English and require correct planning from the administration, and new forms of preparation for classes from the lecturers. In the educational environment, the use of augmented and virtual reality technologies begins – in order to visualize the educational material, supplement it with visual information materials by reading QR code with smartphones, tablets and other gadgets, increase motivation and interest in learning. An important role is played by the ability to work in tandem (a practice widely used by European educational institutions), as well as the ability to self-educate. It is necessary not only the cooperation of teachers of language disciplines with specialized departments and guarantors of specialities, but also access to the resources of other countries, the creation of a special environment that will promote high-quality teaching, learning and use of the English language.
Karl Marx's ideas about the political elite and their influence on political theory and democracy
Authors: Kubatov Shakhobjon
Published: May 2023

This article examines the ideas of Karl Marx about the political elite and their influence on the development of political thought and theory. Marx argued that political power is controlled by small groups of people who use their resources and wealth to protect their interests. This theory became the basis for the development of many other theories, such as elitism and pluralism. The article also discusses the influence of Marx's ideas on understanding the problem of democracy and its limitations, as well as on understanding the social and political dynamics in society.
Between documentary (verbatim) and experimental theater: poetic features of the genre of modern biographical drama (based on comparative analysis)
Authors: Yuhan Nataliia
Published: May 2023

The genre of modern biographical drama is characterized by almost all types of “research biographies” (according to P. Kendell's classification): ironic biography (Thea Dorn, E. Narshi); meaningful and critical biography (R. Veretelnik); “standard” biography (T. Ivashchenko, V. Ognenovich, Nika Simonova); subjectively-interpreted biography (A. Ostermeier, Dea Loher); fictionalized biography (Thea Dorn); pseudobiography (E. Narshi). Among the genre and style innovations of the “biographical drama”, first of all, it is necessary to note the intergeneric approach (plays by T. Ivashchenko, Thea Dorn), as well as the interdisciplinary one – the destruction of barriers between the arts, word, dance, music, video art, visual arts, new media art and ballet (dramas by R. Veretelnik, Nika Simonova, Dea Loer).

New blockchain-based supply chain management system model
Authors: Shmatko Oleksandr , Litvinova Juliya , Shokin Maxim
Published: May 2023

Leveraging technological advances to provide a permanent audit log for a tracked asset is the main goal of blockchain-based supply chain management systems. The challenge, however, is to monitor the asset as it moves through various blockchain-based distribution networks. The paper suggests a model that was developed specifically to solve these problems. The proposed model allows you to do the following: track an asset in various blockchain - based supply chain systems; cryptographically verify the asset's supply chain; define asset data in a standard format; and describe it using several standard formats. Thus, the model offers a significant advantage in terms of interaction between different blockchain-driven supply chains compared to other models presented in the literature.
Agents of Social Change: Cultural Work, Institutions, and the (De)securitisation of Minorities
Authors: Jašina-Schäfer Alina
Published: May 2023

This paper combines anthropological and other critical security studies with research on cultural work to better understand the impact cultural institutions may have on the (de)securitisation of minority groups. Today minority issues represent a recurrent theme in various national and European contexts. Often perceived as a threat to social cohesion and linked to multiple successive crises, minorities and migrants have been the focus of security measures at different times. This paper focuses on the EU-funded project ‘Agents of Change: Mediating Minorities’ and explores how cultural work aimed at diversity and inclusion interacts with the dynamics of securitisation. Zooming in and out between the project goals and definitions, mundane local practices, institutional work and the broader (trans)national contexts, this paper discusses its intervening effects while also acknowledging numerous contradictions that make any straightforward narrative of minority desecuritisation difficult. With the help of empirical examples, this paper demonstrates a way to widen research beyond typical securitising and securitised actors and it contributes to a more nuanced understanding of the contexts of securitisation. Although the countermoves initiated by cultural work are never guaranteed to succeed, studying them opens new pathways to reflect upon the ambiguity of (de)securitisation as an open-ended process involving different actors, power relations and operating at multiple interdependent scales. These countermoves also indicate the shifts taking place in the current ways of thinking about and approaching minorities, challenging dominant constructions driving securitisation.

Published: May 2023

The world is facing major issues associated with the reliance on fossil fuels for energy supply, including rising prices, greenhouse gas emissions, and the risk of depletion. Various technologies have been developed for fixing carbon dioxide, which contributes to global warming. Biological fixation using photosynthetic microalgae cultured on a large scale is a promising method. In this method, carbon should be either wholly stored in the algal biomass or substituted for fossil fuel. Algal biomass can be degraded to carbon dioxide or methane, which is released to the atmosphere. The use of microalgae as a sustainable source of renewable energy and biofuels has garnered significant attention in recent years. One of the advantages of microalgae is their ability to accumulate high levels of lipids, making them a promising feedstock for biofuel production. Moreover, microalgae can be cultivated on non-arable land and can be grown using alternative water sources such as seawater, which further enhances their potential as a sustainable and environmentally friendly energy source. A photo bioreactor (PBR) is essential equipment for microalgal photosynthetic fixation of CO2. A PBR system implemented in a smart bio panel utilizes algae to trap sunlight energy and convert it into electricity, while also generating biomass as a by-product and acting as a CO2 scrubber. To make the system smart, machine learning algorithms were implemented to monitor and predict the growth rate of the algae Support Vector Machines (SVM) were used to predict the growth behavior of the microalgae, and the results showed that the SVM-based model can predict the growth rate of microalgae with a correlation coefficient of 90 percent. Microalgae biomass production heavily relies on photosynthesis, which only utilizes a small portion of the solar energy, mainly in the blue and red wavelengths. However, in traditional microalgae cultivation, the unused portion of the solar spectrum heats up the algae ponds and causes water evaporation, leading to increased salinity, especially in hot and semi-arid locations.
Legal Reform in China: Technology, Transparency, and Enculturation
Authors: Lo Vai Io
Published: May 2023

In China, the diffusion of communication technologies is extensive, as evidenced by the country’s information-technological infrastructure and the accessibility and usage of the Internet, Weibo, WeChat, and short-video hosting services. China’s recent wave of legal reform is the mandate of judicial transparency in terms of adjudicatory process, court trials, adjudicatory documents, and enforcement information. The “rule of law” entails not only an effective legal system but also the legal consciousness of the populace. How the populace appreciates the legitimacy of law and, thus, employs it to protect rights and resolve disputes are essential to the optimal functioning of all legal rules and institutions. Legal enculturation will result in legally conscious individuals who act in accordance with the law. Given that the diffusion of communication technologies in China has been rapid and widespread, this article discusses how communication technology can facilitate both judicial transparency and legal enculturation in China.
The Digitalisation of European Union Procedures: A New Impetus Following a Time of Prolonged Crisis
Authors: Onţanu Elena Alina
Published: May 2023

The COVID-19 pandemic temporarily brought national and cross-border procedures to a standstill. Prior to the pandemic, the use of information and communication technology in court procedures was mostly voluntary and seldom used; although various developments were contemplated, they were slow to be financed and implemented. The pandemic and associated limitations gave digitalisation of procedures, including at the European Union (EU) level, a new impetus and increased authorities’ and professionals’ openness towards technology, including in cross-border judicial cooperation. The measures adopted at the time of writing focus on aspects such as communication between competent national authorities in taking of evidence and service of documents. These are expected to soon be extended to all other EU private international law instruments. In cross-border claims, e-CODEX will be the decentralised information technology system used in this process of facilitating access to justice with digital support. The aim is for identification and certifications of e-signatures and e-identities in this digital environment to be based on the eIDAS Regulation. While all these are welcome developments for facilitating and speeding up access to justice, this paper points out that the process still requires some years for its full implementation and may be exposed to various risks, complexities and challenges. Consequently, the process will not put an end to the EU fragmentation but will work around national and EU realities.
Friday the 13th: The Symbolic Power of Trials on Countering Terrorism with Democracy
Authors: Hayaert Valérie
Published: May 2023

Several years after the outbreak of the Coronavirus pandemic, we are now used to new ways of delivering conferences, new codes of conduct and online etiquette. We are now familiar with the good practices of holding virtual meetings, have improved our knowledge of blended learning and have perhaps challenged the future directions of group debates. However, are virtual interactions within these new technological tools effective substitutions for real interactions? How about rituals and levels of presence? Have these new constraints increased the separation and segregation of audiences? This article aims to explore the implications of the ethics of digital justice when confronted with a particularly traumatic event; that is, the trial of 14 defendants accused of planning and executing attacks on the Stade de France, the Bataclan theatre and bars and terraces in the 11th arrondissement of Paris on Friday, 13 November 2015. The trial is referred to in France by the acronym V13, which stands for Vendredi (Friday) 13, a particularly nightmarish emblem indelibly marked by extreme violence.
Artificial digital life, creation and evolution
Authors: Author A.
Published: May 2023

A.mon are computer programs analogous to biological life, but existing inside the digital environment as an executable file, able to interact with their environment, move around, evolve and hypothetically adapt to new hardware and software, through processes that resemble those found in biological life, although not identical: duplication of their own respective files (reproduction), random alteration of their own binary code (genetic mutation) and natural selection, having the digital environment as a source of selective pressure. Although one of the objectives of this project is adaptation of the digital organisms to new hardware and software autonomously, the original source code is written in the programming languages Go and Python, on Windows 10. Since complexity and diversity are expected to come from evolution, the code is simple and so is the lifespan of the specimens: once their executable files (ancestors) are ran (either by other specimen, a computer user, the computer's start up function, etc.), they access specific sections of their binary codes, randomly alter them by adding, modifying, or removing bytes, and use this mutated binary code to create new executable files (offspring), then they execute the executable files of the offspring and deactivate. The new specimens will restart the process if they're able to thrive. Furthermore, the A.mon have a visual representation in the form of animated sprites that move around on the computer screen, whose appearance, movement patterns, and speed are determined by their binary code, this is useful for easy visualization of new mutations.
Intravesical Bladder Treatment and Deep Learning Applications to Improve Irritative Voiding Symptoms Caused by Interstitial Cystitis: A Literature Review
Authors: Cho Yongwon , Youn Seunghyun
Published: May 2023

Our comprehension of interstitial cystitis/painful bladder syndrome (IC/PBS) has evolved over time. The term painful bladder syndrome, preferred by the International Continence Society, is characterized as “a syndrome marked by suprapubic pain during bladder filling, alongside increased daytime and nighttime frequency, in the absence of any proven urinary infection or other pathology.” The diagnosis of IC/PBS primarily relies on symptoms of urgency/frequency and bladder/pelvic pain. The exact pathogenesis of IC/PBS remains a mystery, but it is postulated to be multifactorial. Theories range from bladder urothelial abnormalities, mast cell degranulation in the bladder, bladder inflammation, to altered bladder innervation. Therapeutic strategies encompass patient education, dietary and lifestyle modifications, medication, intravesical therapy, and surgical intervention. This article delves into the diagnosis, treatment, and prognosis prediction of IC/PBS, presenting the latest research findings, artificial intelligence technology applications in diagnosing major diseases in IC/PBS, and emerging treatment alternatives.

تهدف هذه الدراسة إلى استكناه معالم الأزمة في الأدب المقارن في العلم العربي والتي تتصل اتصالا وثيقا بدعائم الأدب العام من نظرية ومنهج ومصطلح. نقوم بتسليط الضوء على الإشكالات التي طرحتها وما فتئت تطرحها المحاولات الحثيثة لاستنبات وتأصيل النظريات والمناهج الغربية في الأدب والنقد. اتبعنا في هذا البحث منهجا تاريخيا تحليليا لاستجلاء جذور هذه الأزمة وتمثل مخارج ممكنة لها. في مرحلة أولى نقيم مقارنة بين الأدب العربي والغربي لنوضح أن الارتباك الحاصل على مستوى المناهج المتبعة في النقد العربي الحديث مرتبط بكونها وليدة نظريات غربية جاءت نتيجة تحولات جذرية مر بها الإنسان الغربي ولم يخبرها المتلقي العربي إلا كأصداء تأتيه من الغرب، ما أدى إلى اجتراح مفاهيم ومقولات نقدية مستعصية على فهم القارئ العادي. بمعنى آخر، استجابت النظريات الغربية لأسئلة ملحة بخصوص الذات والوجود وعلاقة الإنسان بالعالم وهي أسئلة لم تكن حكرا على المثقف الغربي بقدر ما كانت إشكالات معرفية استشعرها الإنسان الغربي في تجربة معيشة اليومي. أدى التنائي الحاصل بين النظريات والمناهج الغربية من جهة، والذي يصل أحيانا حد التنافر، وجمهور المتلقين العرب من غير ذوي التخصص من جهة أخرى إلى حالة من الركود والتأزم في الوقت الذي نجد فيه ازدهارا للأدب المقارن في الغرب نخلص من هذه الدراسة إلى ضرورة احتواء النظريات الغربية وتجاوزها لخلق نظرية/ نظريات أدبية ونقدية عربية تستجيب لأسئلة معرفية يطرحها رجل الشارع العربي وتنبع من داخل المجتمعات العربية بدل الانقطاع لاستنبات نظريات ومناهج غربية لا تترجم واقع المتلقي العربي ولا تنطق بلسانه.

هدفت الدراسة إلى اختبار أثر المعاملات مع الأطراف ذوي العلاقة على كل من قيمة الشركة وأدائها المالي، وذلك باستخدام عينة من (70) شركة من الشركات غير المالية المدرجة بالسوق المالية السعودية خلال فترة خمس سنوات (2017 – 2021). ولتحقيق هذا الهدف تم استخدام المنهج الاستنباطي والاستقرائي، واستخدام تحليل الانحدار الخطي المتعدد لاختبار فرضيّ الدراسة والتي تنص في الفرض الأول: تؤثر المعاملات مع الأطراف ذوي العلاقة معنويًا على قيمة الشركة، والفرض الثاني: تؤثر المعاملات مع الأطراف ذوي العلاقة معنويًا على الأداء المالي للشركة. وقد توصلت الدراسة إلى عدم وجود تأثير للمعاملات مع الأطراف ذوي العلاقة على كل من قيمة الشركة وأدائها المالي، وذلك باستخدام قيمة المعاملات مع الأطراف ذوي العلاقة. وباستخدام متغير وهمي لقياس المعاملات مع الأطراف ذوي العلاقة، توصلت الدراسة إلى وجود تأثير إيجابي ومعنوي للمعاملات مع الأطراف ذوي العلاقة على قيمة الشركة. وأخيرًا، توصلت الدراسة إلى وجود تأثير إيجابي ومعنوي للمعاملات مع الأطراف ذوي العلاقة على قيمة الشركة في الفترة التي سبقت جائحة COVID-19 وتوصي الدراسة بضرورة اهتمام هيئة السوق المالية بتوفير إرشادات لتوجيه الشركات لتحسين استخدامها للمعاملات مع الأطراف ذوي العلاقة، والاستفادة من المزايا العديدة التي توفرها. كما توصي بضرورة اهتمام مجالس إدارة الشركات بزيادة مستوى افصاحها عن تلك المعاملات؛ وذلك لزيادة شفافية القوائم المالية وتحسين صورة الشركة أمام أصحاب المصالح، وتوعية المستثمرين بأهمية المعاملات ذوي العلاقة كأداة يمكن استخدامها في تحويل موارد الشركة من قبل الأطراف المسيطرة على حساب صغار المستثمرين.
Study on Comparative Performances of Selected Paddy Weeders Developed in India
Authors: Sapunii Sebastian  , Karuna Kalita
Published: May 2023

Various types of paddy weeders, for dry as well as wet-land conditions, have been developed and used in India. The commonly used wetland paddy weeders under Indian conditions are rotary power weeder, cono-weeder, and Ambika weeder; whereas, hoe-type weeders are mostly used under dry-land conditions. The common and effective type of weeder is two-row power-operated rotary type of 0.0793 ha.h-1 field capacity. The average cost of operation and weeding efficiency of existing paddy weeder is 1,169.59 `.ha-1 and 79.92%, respectively. A review undertaken on different types of paddy weeders developed by researchers in India indicated that most of the developed weeders are designed for the use in inter-row cultivation, and limited research has been conducted for intra-row weeding. Thus, research should focus on developing inter-cum-intra-row weeders which could increase weeding efficiency and crop yield.

The present study was conducted to optimize the mouth piece diameter and suction pressure of plug tray seeding mechanism of pneumatic seeder for cabbage seeding. The seeding mechanism consisted of a seeding pipe with hypodermic needles as seed picking units, a cut-off device for supplying/cutting suction, a pressure regulating assembly consisting of a vacuum gauge and pressure control valve, and a suction unit. The seeding unit was connected to the pressure regulating assembly by a flexible pipe for easy operation. The responses namely, per cent miss, per cent multiple, per cent single, output, and seed damage were determined in the laboratory for different levels of mouthpiece diameter and suction pressure. Mouthpiece diameter of 0.84 mm and suction pressure of 5.9 kPa were found suitable for cabbage seeding with 92.88% singles and 69 cell.min-1 output capacity. As germination percentage was not affected by the mouthpiece diameter and suction pressure, the quality of the seeds could be expected to remain unaltered.
