Authors: Nos Rudimar , Sano Mari , Tavares Maria
Published: February 2023

We developed in this work the computation of the volume of the sphere via the method of exhaustion by inscribed truncated right cones. We show that this computation can be used in calculus courses in several ways; mainly, to motivate and clarify the usage of the squeeze theorem in the computations of sum limits. As a result, we generalized a sum limit using Bernoulli numbers, producing a magnificent example of applied mathematics, and highlighting the importance of exploring when studying mathematics.
O OLHAR DE UMA PROFESSORA DE MATEMÁTICA A RESPEITO DAS AVALIAÇÕES EXTERNAS E O CURRÍCULO OCULTO
Authors: Machado Nilza , Godoy Elenilton
Published: February 2023

Alarmado com os fatores que envolvem os processos de ensino e aprendizagem da disciplina de Matemática na Educação Básica e com os/as docentes e discentes diante dos desafios presenciados no espaço escolar, o presente artigo tem como objetivo refletir a respeito das avaliações externas e sua relação com o currículo oculto, mais particularmente, em uma escola pública de Curitiba. Para esse fim, a pesquisa se pautará metodologicamente numa abordagem qualitativa, de cunho etnográfico utilizando a técnica da observação participante e apoiar-se-á em teóricos críticos do campo do currículo que investigam o currículo oculto. O exercício analítico realizado indicou a carência de atitudes autônomas, uma presença evidente de obediência, individualismo e um conformismo atuante nos diversos segmentos dessa comunidade escolar.  Evidencia-se que as ações do currículo oculto que se apresenta, ainda são de validação e aceitação das avaliações centralizadas ofertadas pelas instituições externas à escola e que o corpo docente se apresenta carente de percepção das intencionalidades desses órgãos.

Biocybersecurity and Deterrence: Hypothetical Rwandan Considerations
Authors: Samori Issah , Odularu Gbadebo , Potter Lucas , Palmer Xavier-Lewis
Published: February 2023

Digitalization and sustainability are popular words within modern disciplines as practitioners each look toward the future of their respective fields. Specifically for the African continent, which is making great strides in developmental targets, those two terms are central to core aspects of policy initiatives that may foster cooperation across its varied lands and nations. One of the underlying challenges that confront Africa is a lack of strong regional integration across socioeconomic and political programs; there is value in African regions having more regional connectedness. We assess the rate of regional integration and development in Africa and discuss how to alleviate development crises that could be accelerated by deploying a sustainable cybersecurity strategy, which increasingly includes the bioeconomy and its components. This can be done through the application of Fourth Industrial Revolution (4IR) technologies such as Artificial Intelligence (AI) and modern biotechnology. This work suggests that political and socio-economic activities associated with regional integration must be seen as an all-encompassing task that transcends beyond national boundaries towards a cyber biodefense fortification and increases in 4IR technological integration. This has the aim of thereby encompassing efforts to persuade leaders to fast-track policies that seek to promote geospatial cyberinfrastructure, integrative cybersecurity considerations, cross-border digitalization programs, and increased need for cybersecurity research and education, with mindfulness towards education and further integration of mindful automation. In conclusion, a model of integrative security is proposed for Africa.
Social Robots Privacy Enhancement Using Colored Petri Net (CPN) for Behavior Modeling: A Case Study of Asus Zenbo Robot
Authors: Yankson Benjamin , Iqbal Farkhund , AlMaeeni Fadya
Published: February 2023

The interactions between a social robot and the user consist of continuous communication and behavior involving different data types that can be subject to cybersecurity attacks and prone to user privacy concerns. In this paper, we use Colored Petri Net (CPN) to develop two graphical models that illustrate different patterned behavior of a robot during such interaction. Using CPN, we model and analyze complicated robot system interactions considering synchronization and concurrency of events that can be subject to privacy violations. We focus on two specific scenarios involving user registration and medication reminder to provide an efficient illustration of the objects and events collaborated to carry out the intended tasks of the robot pertaining to privacy issues. The results show that CPN modeling simulation can capture and represent the robot's behavior, provide a better understanding of the task execution, and highlight users' privacy gaps requiring immediate controls.

Published: February 2023

The Internet of things (IoT) has revolutionized many aspects of the world, including industrial systems, automobiles, home automation, and surveillance, to name a few. IoT has offered a multitude of conveniences for our daily lives, such as being able to control our thermostats remotely, view our home surveillance cameras while away, or have a smart television that can surf the web. However, the widespread adoption of IoT devices combined with their vast device vulnerabilities results in significant security risks reinforcing the need for more robust default security controls and public awareness. As such, this paper aims to discover and document security vulnerabilities in the   Asus Zenbo Junior IoT robot, along with providing a few best practices when securing smart home devices. This work presents an experiment using several security vulnerability assessment tools such as Nmap and OpenVAS scans to assess cybersecurity vulnerability currently present on Zenbo based on the 4P forensic investigative framework. The result of the experiment shows multiple open ports were discovered, along with miscellaneous information that an attacker could use to their advantage to attack the Zenbo robot. Based on the result, this work presents various security precautions that can help users protect against cyber-attack.
Social-Engineering, Bio-economies, and Nation-State Ontological Security: A Commentary
Authors: Griffin Brandon , Alexander Keitavius , Palmer Xavier-Lewis , Potter Lucas
Published: February 2023

Biocybersecurity is an evolving discipline that aims to identify the gaps and risks associated with the convergence of Biology (the science of life and living organisms) and cybersecurity (the science, study, and theory of cyberspace and cybernetics) to protect the bioeconomy. The biological industries’ increased reliance on digitization, automation, and computing power has resulted in benefits for the scientific community, it has simultaneously multiplied the risk factors associated with industrial espionage and the protection of data both commercial and proprietary. The sensitive and potentially destructive power of this data and its access inherently poses a risk to the national and ontological security of a nation. Ontological security refers to the extent to which an individual or group feels secure in their understanding of the world and their place in it. It is a psychological concept that pertains to the way in which people construct their sense of self and their place in the world, and how this sense of self and place is shaped by their interactions with others and the broader social, cultural, and political context in which they live.  Nation-states provide stability and wider social cohesion, but these capacities can be disrupted when the nation state is sufficiently threatened (Bolton, 2021). Leading to an interest in maintaining a national identity; which can have profound effects on the behavior of a nation. Targeted social engineering is aimed at exploiting the changing and damaged mental health of workers in life science enterprises who have not been trained in a sufficient manner to deal with these attacks. Failure to identify the existing vulnerabilities associated with social engineering would expose the bioeconomy to unnecessary risk. Numerous scholars have pointed towards growing risks of nation-state stability being increasingly threatened vs inadequate actions taken to match threats for defense; when reflecting on energy, food, construction materials and more from the multi-trillion US bioeconomy we see that the ground to cover is huge (George 2019, Jordan, 2020, Murch, 2018; Mueller 2021).  This paper seeks to discuss some of the existing vulnerabilities associated with social engineering attacks and the effects those attacks would have on the population's ontological security and spark conversations about ways in which ontological security of nation states are modified.
Offensive Cyberspace Operations for Cyber Security
Authors: Huskaj Gazmend
Published: February 2023

This work-in-progress research product covers Offensive Cyberspace Operations for Cyber Security or “Offensive Defense” for Cyber Security. Offensive cyberspace operations are shrouded in secrecy. From an intelligence perspective, this makes sense because of their development since Operation Desert Storm in 1991. The phenomenon, dubbed “Information Warfare,” and to the professionals’ surprise, they could remotely turn off an Iraqi power substation. However, the implication of remotely turning off the power substation was not only to cut off the power source to an Iraqi military headquarters, but it also meant cutting off the power to a nearby hospital, risking the lives of injured Iraqi soldiers protected by the Geneva Conventions. Since the 2000s and onwards, and with the US military recognizing cyberspace as a war-fighting domain, establishing United States Cyber Command (USCYBERCOM) may be a milestone. Thus, researchers have put much thought into cyberspace operations (offensive, defensive), such as doctrine, organizations, training, materials, leadership and education, personnel, facilities, and policy. One phenomenon, dubbed “defending forward,” was coined in the 2018 US Department of Defense Cyber Strategy. The idea is simple: take the fight to the adversary. Other terms include “hunt-forward operations” and “offensive defense.” Therefore, what is “Offensive Defense” for cyber security, and why now?
Towards a Critical Review of Cybersecurity Risks in Anti-Poaching Systems
Authors: Steyn Christelle , Blaauw Dewald Neville
Published: February 2023

Anti-poaching operations increasingly make use of a wide variety of technology for intelligence and communications. These technologies introduce cybersecurity risk, and they need to be secured to provide greater protection to the information and people involved in anti-poaching operations, ultimately protecting vulnerable animals better. A hypothetical network of anti-poaching technologies was simulated in Graphical Network Simulator 3 (GNS3), consisting of various field devices identified in the literature, and a main control room with relevant hardware devices. A virtual Kali Linux machine was connected to the network and played the role of a digital attacker or intruder. Several cyber-attacks were carried out, to show the risks inherent to such an interoperable and socio-technical network. These attacks included Man in the Middle (MitM) and Denial of Service (DoS) attacks. These attacks were then mitigated via system configurations. Further risks and threat considerations were identified in the literature. Using the STRIDE, DREAD and Attack Tree threat models, the risks to an anti-poaching network were classified and calculated. The most prevalent threats and the attacks performed in the simulation were all calculated to have a high risk level, posing a great threat to an unsecured network. The STRIDE classes of Denial of Service and Elevation of Privilege posed the most risk to the system, both having a calculated average risk score of 9 out of 10. Mitigations to general network threats and those identified in the simulation are mentioned. Additionally, authentication for such a system was investigated, as improper authentication practices were deemed a risk and provides a foothold for further risks in the network. Recommendations made, include the proper configuration of network devices, especially the router and switch, and the use of anti-virus, firewalls, and intrusion detection systems, as well as having an external audit performed annually. Multi-factor authentication, with a password/fingerprint combination, is recommended.
Blockchain Forensics: A Modern Approach to Investigating Cybercrime in the Age of Decentralisation
Authors: Salisu Saminu , Filipov Velitchko
Published: February 2023

Blockchain forensics (the use of scientific methods to manipulate data to create useful and informative descriptions of the manipulated data) takes data from the blockchain to interpret the flow of digital assets. Investigators use sophisticated data manipulation and visualization tools to identify the travel history of stolen assets. With these capabilities, chain hopping, round-tripping, and all attempts to blur transfer trails by cyber criminals become smoke screens with no effect. This paper establishes a framework for investigating financial crimes on the blockchain, starting with a brief explanation of blockchain forensics, types of financial crimes committed by criminals using the blockchain, and how they can be mitigated using OSINT’s (OSINT, 2022) investigation process of data collection, data preservation, data processing, and data presentation. This paper also presents a community-based approach to financial crime investigations on the blockchain that involves the public and victims themselves contributing valuable intelligence that can be used to trace and track criminals by authorities and security agencies in the global fight against cybercrime.
Towards the Usefulness of Learning Factories in the Cybersecurity Domain
Authors: Veerasamy Namosha , Mkhwanazi Thuli , Dawood Zubeida
Published: February 2023

The success of an organisation depends on its employees’ skills and the extent to which they are developed. Although organisations often assume employees are fit and ready for a new position or new developments in their functions, employees need adequate training before, during and after effective performance in their respective roles. Amongst other important roles, training is significant in problem-solving, continuously improving skills, and creating consistency or culture in the work environment. Nonetheless, the significance of training is often disregarded or not understood by organisations as there are often inadequacies, inconsistencies, and ignorance from the employer.

Furthermore, organisations are facing cybersecurity skills shortages. Some specialists leave the profession due to a lack of skills or support. The lack of experienced and qualified cyber security specialists increases the risk of IT system systems being targeted with cyber-attacks. Having insufficient cybersecurity staff, companies may struggle to protect their networks from attacks. Organisations are being placed into a troubling position as the threat landscape continues to evolve. With the growth in volume and sophistication of cyber security attacks, the problem of a skilled workforce is exasperated.

In order to support the cybersecurity workforce, this paper proposes the implementation of learning factories. Typically, learning factories have been used in the manufacturing sector. However, the fundamental principles and guiding ideologies can also be applied in the cybersecurity domain.  Learning factories provide a mechanism to remove the barriers of entering the field of cybersecurity by cultivating and nurturing a cybersecurity workforce. They enable the broadening of the scope for talent and change our current working practices and tighten the gap between education and experience. The closing of the talent gap is an important imperative for cybersecurity. In this paper, a motivation and description of the functionality of learning factories for cybersecurity is provided. Through this paper the benefits of learning factories will be highlighted in order to show the advantages of active engagements in learning activities, real-world application and information sharing.

Published: February 2023

В статье представлены методология и результаты DDD-анализа потребления антибактериальных препаратов резерва, его возможности в принятии управленческих решений в инфекционном контроле по профилактике антибиотикорезистентности. В основе системы лежит мониторинг универсальной единицы измерения потребления лекарственного средства Defined Daily Dose (DDD), рекомендованной ВОЗ. Проведение DDD-анализа потребления антибактериальных препаратов резерва с учетом данных микробиологического мониторинга помогает оптимизировать применение антибиотиков, что сдерживает рост резистентности микроорганизмов в конкретном стационаре, снижает не только прямые необоснованные затраты на антимикробные препараты, но и непрямые экономические потери. Представленный в статье DDD-мониторинг антибиотиков резерва имеет высокую значимость для практического здравоохранения и является действенным микро- (на уровне структурного подразделения и учреждения здравоохранения) и макро- (на уровне региона и страны) экономическим инструментом управления антимикробной терапией (АМТ).

The article presents the methodology and results of DDD analysis of the consumption of antibacterial drugs of the reserve, its capabilities in making managerial decisions in infection control for the prevention of antibiotic resistance. The system is based on the monitoring of the universal unit of measurement of drug consumption Defined Daily Dose (DDD), recommended by WHO. Conducting a DDD analysis of the consumption of reserve antibacterial drugs, taking into account microbiological monitoring data, helps to optimize the use of antibiotics, which inhibits the growth of resistance of microorganisms in a particular hospital, reduces not only direct unreasonable costs for antimicrobials, but also indirect economic losses. The DDD monitoring of reserve antibiotics presented in the article is of high importance for practical healthcare and is an effective micro- (at the level of a structural unit and a healthcare institution) and macro- (at the level of a region and country) economic tool for managing antimicrobial therapy (AMT).

AbstractSnakehead fish (Channa sp.) is one of Indonesia's native freshwater commodities that has been successfully domesticated by fish farmers, yet the domesticated snakehead fish culture still has problems, namely the low survival and growth of local snakehead fish. Overcoming this problem requires a technology that can optimize the survival and growth of the domesticated snakehead fish (Channa sp.). One technology that can be applied is the use of probiotics. This reserach aimed to examine different probiotics through feed to optimize the survival and growth of domesticated snakehead fish (Channa sp.). This research was conducted with an experimental method. The experimental design used was a completely randomized design with 4 treatments and 3 replications. The treatments were control treatment (P0), treatment with probiotic composition of Lactobacillus sp., Bacillus spp. and Nitrosomonas sp. (P1), treatment with probiotic composition of Lactobacillus casei and Saccharomyces cerevisiae (P2), and treatment with probiotic composition of Lactobacillus sp., Acetobacter, Rhodobacter sp., yeast (P3). The results showed that different probiotic feeding had a significant effect (P<0.05) on the survival parameters and different probiotic feeding compositions had no significant effect (P>0.05) on the growth parameters. The composition of Lactobacillus casei and Saccharomyces cerevisiae probiotics is the best probiotic composition to increase survival and growth of domesticated snakehead fish.Keywords: Domestication, Growth, Survival Rate, Probiotic

Atendiendo a las condiciones y protocolos sanitarios para el trabajo de campo se realizó un primer relevamiento de datos a través del WhatsApp, estableciendo diálogos con los contactos de las comunidades con quienes venimos trabajando desde hace más de diez años. Luego, se realizaron visitas breves a la comunidad del barrio Mapic durante el Distanciamiento Social Preventivo y Obligatorio (DISPO) donde se recopilaron entrevistas semidirigidas.

La concentración de tierras en pocas manos genera que gran parte de la población viva en espacios tomados, tanto en el campo como en la ciudad. A partir de dos investigaciones etnográficas desarrolladas en Argentina, una en Ciudad de Buenos Aires y otra en el departamento de Orán (provincia de Salta), el objetivo del presente trabajo es analizar los modos en los que la ocupación ilegal de la vivienda configura diversos aspectos de las vidas de lxs niñxs. Los resultados se presentan en tres ejes de análisis: la configuración intergeneracional de lo común/lo privado/lo público/lo íntimo en un contexto de escasez de espacio; la experiencia del temor como dimensión de la precariedad habitacional para la infancia y, por último, la participación de lxs niñxs en la organización política y familiar para garantizar su supervivencia.

En 2011 la Universidad Nacional de Avellaneda abría sus puertas y nos brindaba la posibilidad de iniciar una investigación que se mantiene aún en desarrollo. Nos proponíamos construir información sobre el entorno regional en que se inserta la universidad. Por ello el Conurbano bonaerense enmarcó todo el desarrollo de nuestros proyectos, y adoptamos una mirada que nos alejaba de aquella que piensa este territorio como una periferia. Específicamente, nos propusimos estudiar las condiciones de vida y las estrategias de reproducción de un grupo de las clases populares y aportar a una perspectiva teórica de economía popular. En este artículo presentamos el recorrido realizado, un recorrido que nunca fue lineal ni sencillo. Sobre las dudas, los interrogantes y las incertidumbres trazamos el derrotero que presentamos.

Coromines (1989-1997) dóna diferents etimologies a topònims com Llorts i Llordà (lurte: ‘esllavissada de terres’), Lord i Lourdes (lúrrite: ‘penya de roca’), Lòria i Salòria (alod: ‘alou’), Hortell, Hortó i Hortoneda (art: ‘nom preromà de planta’, ‘arç’), etc. Nosaltres, a partir de l’anàlisi geomorfològica d’aquests indrets observem que aquests topònims i molts d’altres guarden una estreta i clara relació amb vessants que presenten o han presentat en el passat inestabilitats (grans moviments, esllavissades superficials, corrents d’arrossegalls, etc.). Atesa aquesta estreta relació, postulem que caldria no desbancar la possibilitat d’incloure’ls tots dins la mateixa família lurte. Tanmateix, tenint en compte que lurr apareix amb doble vocalisme lurr i lorr i que ha donat mots com lorrin ‘terra remoguda’ o lortu ‘transportar...
