IoT Hacking – A Primer
Authors: Papp Dorottya , Tamás Kristóf , Buttyán Levente
Published: December 2020

The Internet of Things (IoT) enables many new and exciting applications, but it also creates a number of new risks related to information security. Several recent attacks on IoT devices and systems illustrate that they are notoriously insecure. It has also been shown that a major part of the attacks resulted in full adversarial control over IoT devices, and the reason for this is that IoT devices themselves are weakly protected and they often cannot resist even the most basic attacks. Penetration testing or ethical hacking of IoT devices can help discovering and fixing their vulnerabilities that, if exploited, can result in highly undesirable conditions, including damage of expensive physical equipment or even loss of human life. In this paper, we give a basic introduction into hacking IoT devices. We give an overview on the methods and tools for hardware hacking, firmware extraction and unpacking, and performing basic firmware analysis. We also provide a survey on recent research on more advanced firmware analysis methods, including static and dynamic analysis of binaries, taint analysis, fuzzing, and symbolic execution techniques. By giving an overview on both practical methods and readily available tools as well as current scientific research efforts, our work can be useful for both practitioners and academic researchers.

This article focuses on the physical layer of the VLC links. It reviews the technology, the topology of the proposed connection, and the benefits of this approach. The main research trends are identified emphasizing state of the art in this area. It shows how VLC technology evolved and what are the performances achieved at this time. Various structures of the transmitter and receiver are studied, and different modulation schemes are investigated. Finally, numerous applications of VLC technology are presented.
When Myth-Building Meets Nation-Branding: Fabricating the “Swedish Educational Model” in French Media Discourse (1964–2019)
Authors: Colla Piero
Published: December 2020

The educational reforms carried out in Sweden have aroused persistent interest in the French public debate. This paper focuses on the evolution of the media’s portrayal of an alleged Swedish “educational model,” by highlighting cross-national influences over an extended time horizon. The origin of a stereotype is addressed from the point of view of the interaction between the Swedish branding of its own model and the demand, on the part of French elites, for a handy reform paradigm. Two crucial phases of idealisation are identified. At first, the popularity of the Swedish experiment in education coincides with the idealisation of Sweden as a laboratory for social reform. Since 2010, TV reporting has focused on both the resistance of this myth and the diversity of its possible uses. The expansion of market-oriented principles in educational culture is stigmatised as a “betrayal” of values associated with the Swedish reform experience (pupil autonomy, inclusiveness, anti-authoritarianism), while other players—such as international ranking organisations—intervene in shaping the media image.
La resistencia étnica entre los Bakairí (Karib).
Authors: Barros Edir Pina de
Published: December 2020

Short description:The Bakairí are one of Brazil's indigenous groups which speak the Karib language. Major changes occurred in their lives in the last century and only their social flexibility and political adaptability allowed them to survive in a culturally, socially and economically hostile environment. This article dedicates special attention to the ways in which they manage to keep their own socio-cultural hierarchy and history and continue to exist among other peoples, while maintaining their distinct ethnicity.

Published: December 2020

Introduction: Observational studies indicate a significant impact of serum 25(OH)D concentration on incidence of hospital-acquired infections. However, we did not find any interventional study assessing the effect of vitamin D3 administration at the admission on the course of further hospitalization in internal medicine departments.

Objective of the paper: Investigation of the impact of one-time high-dose vitamin D3 administration in elderly patients on the day of urgent admission to the hospital, on hospital-acquired infections.

Materials and methods: A randomized, two-arms, open pilot study in 97 adults aged 60-100. A study group was given a single dose of 60,000 IU vitamin D3 and a control group was not subject to any intervention. Serum 25(OH)D and calcium were measured at the baseline and after 7 days.

Results: 77.32% of studied patients were vitamin deficient, and among those, in 28.87% severe vitamin D deficiency was found. After single administration of 60,000 IU of vitamin D3, only 4 patients achieved recommended serum 25(OH)D concentration. The highest increase in serum 25(OH)D was observed in patients with severe deficiency. Numbers of observed nosocomial infections such as flu, hospital-acquired pneumonia or Klebsiella pneumoniae MBL+ infection did not differ significantly between study and control group, however there was a trend close to significance for lower incidence of Clostridium difficile infection in the vitamin D3 group.

Conclusions: Preliminary results of the presented research indicate possible protective effect of single high dose of vitamin D3 against Clostridium difficile infection during hospitalization. Further research on larger group of patients, using higher dose of vitamin D3 is necessary.

No tratamento da água potável são utilizados produtos clorados de modo a garantir o nível de segurança sanitária exigido. Contudo, na presença de precursores, pode ocorrer a formação de Subprodutos da Desinfecção (SPD) em decorrência da reação com o cloro. O SPD Cloral Hidratado (CH), composto hipnótico e sedativo, tem sido encontrado na água, no entanto não é citado no padrão de potabilidade brasileiro. Este trabalho tem como objetivo geral avaliar o risco toxicológico do CH a partir de ensaios específicos e calcular um Valor Máximo Permissível (VMP). Roedores foram expostos a diferentes concentrações padronizadas de CH e submetidos a análises bioquímicas e bioensaios comportamentais e de locomoção, tais quais os de campo aberto, indução de sono e rotarod. Foi identificado o Nível de Efeito Adverso Não Observado (NOAEL) na dose 9,60 mg.kg-1.d-1, obtendo-se o VMP de 2,3 mg.L-1 de CH; considerando o Nível de Menor Efeito Observado (LOAEL) na dose 0,96 mg.kg-1.d-1, obteve- se o VMP de 0,023 mg.L-1 de CH, valor próximo ao 0,02 mg.L-1 citado nos padrões da Austrália (2017) e da Nova Zelândia (2017).

Published: December 2020

Os processos de fotocatálise heterogênea e adsorção são apontados como alternativas economicamente favoráveis para remoção de contaminantes em água e fazem parte de uma das áreas mais intensamente investigadas devido ao caráter promissor de suas aplicações. Porém, como o gargalo da aplicação tecnológica da fotocatálise heterogênea é a retenção e a reutilização do fotocatalisador dióxido de titânio, faz-se ainda necessário estudar técnicas para sua imobilização em suportes sólidos. Este artigo tem como objetivo apresentar o potencial do processo de fotocatálise heterogênea consorciado à adsorção para o tratamento de água contendo Microcystis aeruginosa e seus metabólitos. O uso de argilominerais se mostra bastante promissor nas áreas de adsorção e catálise voltadas para o saneamento ambiental.

Published: December 2020

Este trabalho estudou o efeito da temperatura e da concentração inicial de cloro sobre os valores das constantes cinéticas de decaimento em massa (kb) utilizadas nos modelos matemáticos que simulam a qualidade da água, para dois tipos de água, uma de origem superficial e outra de origem subterrânea com valores de carbono orgânico total (COT) distintos. Os resultados mostraram que a variação é diretamente proporcional à temperatura e inversamente proporcional à concentração inicial do desinfetante na água. Para concentrações iniciais próximas a 1,00 mg L-1, os valores das constantes cinéticas para faixas de temperatura de 13 a 14 °C, 20 a 21 °C e 30 a 31 °C foram, respectivamente, iguais a 0,0720 dia-1, 0,1680 dia-1 e 0,3024 dia-1 para águas superficiais e 0,0168 dia-1, 0,0264 dia-1 e 0,0480 dia-1 para águas subterrâneas. Concentrações iniciais de 0,97 mg L-1 e 1,85 mg L-1 em amostras de água superficial, por exemplo, mantidas à temperatura de 20 a 21 °C, geraram coeficientes cinéticos iguais a 0,1680 dia-1 e 0,0696 dia-1, respectivamente. Para essa mesma faixa de temperatura, e amostras de água subterrânea com concentrações iniciais de 0,97 mg L-1 e
1,81 mg L-1, os valores de kb foram iguais a 0,0264 dia-1 e 0,0168 dia-1.

Published: December 2020

Na Norma Brasileira NBR 12.209/2011, o Filtro Biológico Percolador - FBP apresenta a possibilidade de uso de meio suporte plástico, com novos valores para os parâmetros de referência. Para tanto, os parâmetros de projeto, como a carga orgânica volumétrica (COV), a taxa de aplicação superficial (TAS) e a profundidade do filtro (H), foram alterados para se adequarem melhor às particularidades desse meio suporte. Nesse sentido, este trabalho visa apresentar uma análise crítica dos valores limites estabelecidos para esses parâmetros, por meio de cálculos teóricos. Observou-se que as vantagens associadas à utilização do meio suporte plástico, de possibilidade de aplicação de COV elevada e de elevada profundidade de meio suporte (até 12 m), com a consequente redução de área ocupada, não são facilmente alcançadas. Ao se elevar a profundidade do meio suporte ao limite determinado pela Norma, alcança-se uma carga orgânica volumétrica bastante inferior àquela sugerida para este fim e taxas de aplicação superficial superiores ao limite máximo recomendado. Alcança-se no máximo 9,0 m de profundidade, considerando-se o FBP precedido pelo Reator UASB, com
TAS = 75 m3.m-2.d-1 e COV = 1,0 kgDBO.m-3.d-1. Para a mesma TAS e COV = 1,5 kgDBO.m-3.d-1foi possível alcançar somente 6,0 m de profundidade de meio suporte.

Design of realistic chewing trajectory for dynamic analysis of the dental prosthesis
Authors: Wenlong Qin  , Ming Cong  , Xiang Ren  , Haiying Wen
Published: December 2020

Purpose: The chewing trajectory in the dynamic analysis of dental prosthesis is always defined as a two-segmental straight polyline without enough consideration about chewing force and motion laws. The study was aimed to design a realistic human chewing trajectory for the dynamic analysis based on force and motion planning methods. Methods: The all-ceramic crown restored in the mandibular first molar was selected as the representative prosthesis. Firstly, a dynamic model containing two molar components and one flat food component was built, and an approximate chewing plane was predefined. According to the desired forces (25 N, 150 N and 25 N), three force planning points were calculated by using tentative trajectories. The motion planning was then executed based on four-segment cubic spline model. Finally, the new trajectory was re-imported into the dynamic model as the displacement load for evaluating its stress influence. Results: The maximum lateral velocity was 26.81 mm/s. Besides, the forces in the three force planning points were 14.11 N, 126.75 N and 13.56 N. The overall repetition rate of chewing force was 77.21%. The force and stress profiles were similar to the sine curve on the whole. The maximum dynamic stress of the crown prosthesis was 398.5 MPa. Conclusions: The motion law was effectively brought into the chewing trajectory to introduce the dynamic effect. The global force performance was acceptable, and the force profile was more realistic than the traditional chewing trajectory. The additional reliable characteristic feature of the stress distribution of the dental prosthesis was observed.

Authors: Wądołowski Piotr , Krzesiński Grzegorz , Gutowski Piotr
Published: December 2020

Purpose: The purpose of this study was to analyze three patterns of mandible angle fracture treatment by means of the finite element analysis. Methods: Investigation has been based on the mandible geometry reconstructed with use of hospitalized patient CT data. The KLS Martin mini-plates with corresponding screws were used to establish proper fracture stabilization. Models were run assuming isotropic and elasto-plastic material properties of connecting devices and cortical bone. The main masticatory muscles and artificial temporomandibular joint have been incorporated to assure mandible physiological movement. The gage loading has been applied in three different locations to cover wider range of possible mastication loading cases during daily routine. A different contact conditions have been applied to the fracture plane to simulate both load bearing and sharing behaviors. Prepared FEM models reflect the most frequently used surgery’s approaches to mandible angle fracture treatment. A specific nomenclature has been introduced to describe particular model. The tension plate, with one connecting mini-plate, two-point fixation and combined fixation, both using two mini-plates respectively. Results: Performed analysis allowed for a detailed estimation of the mini-plate connection response under the applied gauge loading. The equivalent stress within the mini-plates and surrounding cortical bone have been compared between all models. Regarding the fracture plane, the contact status and pressure have been considered. Conclusions: The combined fixation model, acting as a biplanar fastener system, presents the highest flexibility and connection efficiency.

Published: December 2020

Purpose: Long-distance running has been a global popularity, and differences may be observed in runners of experience. This study was aimed to evaluate the differences in plantar loading between experienced long-distance runners and novice runners during walking. The hypotheses were that smaller load in the middle of the forefoot and the stable foot balance would be observed in experienced runners during walking. Methods: Twenty-five participants were recruited as the experienced runners group (ten: frequency ≥ 4 times/week and distance ≥ 40 km/week, for over 1 year) and the novice group (fifteen: frequency ≤ 2 times/week and distance ≤ 10 km/week, for less than 1 year). Results: The peak Meta loading showed that the novice runners were significantly larger than the experienced runners (p ≤ .001). The occurring time of peak Meta loading was significantly delayed compared to the experienced runners (p = .050). Peak Foot balance was higher in the novice runners group (p ≤ 0.001). Conclusions: This study highlighted the findings of the potential differences of plantar pressures and foot functional parameters during walking in experienced runners and novice runners, specifically the contact duration of phases during stance, toes functions and medial-lateral loading shifting (foot balance) and metatarsals (central forefoot) offloading.

Published: December 2020

Purpose: The aim of this paper was to evaluate the effects of breathing retraining with chest wall mobilization on the onset of accessory breathing muscle recruitment and respiratory reserve in individuals with chronic neck pain. Methods: Thirty-two participants with non-specific chronic neck pain were randomly assigned into intervention and control groups. The intervention group received 30 minutes of breathing retraining with chest wall mobilization and the control group was assigned to rest for 30 minutes. Electromyography (EMG) of upper trapezius (UT), scalene (SC), and sternocleidomastoid (SCM) muscles were recorded during respiratory excursions by cycling for 12 minutes. Measurement of maximum voluntary ventilation (MVV), chest expansion, and pain intensity were taken during normal breathing. The immediate effects within each group and between two groups were analyzed. Results: Significant improvement in respiratory reserve was observed in the intervention group compared to control group through prolonged EMG onset of accessory breathing muscles. Moreover, increase of MVV, chest expansion and decrease in pain intensity were observed. Conclusions: This research suggests that breathing patterns and chest expansion should be considered within the physical assessment of breathing retraining, and that chest wall mobilization offers clinically important improvements in patients with chronic neck pain.
Frequency Security Constrained Energy Management in an Isolated Power System
Authors: Akram Umer , Nadarajah Mithulananthan , Shah Rakibuzzaman , Shafiq Saifullah
Published: December 2020

Short-term frequency instability is one of the major challenges that arise due to large-scale penetration of converter interfaced renewable energy sources (RESs) in isolated power systems. The short-term frequency instability is associated with high values of rate of change of frequency (RoCoF) and larger frequency excursions. In this paper, a frequency constrained energy management algorithm is proposed. The proposed algorithm manages the power output of RESs, energy storage system, and electric vehicles (EVs) in such a way that the system keeps nonsynchronous power reserve for providing virtual inertia support to avoid high values of RoCoF and frequency excursions. The non-synchronous power reserve is readily available and when deployed can limit the RoCoF as per the required standard. The proposed management algorithm selects the non-synchronous power reserve from different resources, i.e., RES (solar PV, wind turbine), energy storage, and EV, depending on the availability and system loading conditions. Simulation results show the effectiveness of the proposed algorithm.

DNA with zwitterionic and negatively charged phosphate modifications: formation of DNA triplexes, duplexes and cell permeability studies
Authors: Su Yongdong , Bayarjargal Maitsetseg , Hale Tracy K , Filichev Vyacheslav V
Published: December 2020

Two phosphate modifications were introduced into the DNA backbone using Staudinger reaction between the 3’,5’-dinucleoside β-cyanoethyl phosphite triester formed during DNA synthesis and the sulfonyl azides, 4-(azidosulfonyl)-N,N,N-trimethylbutan-1-aminium iodide (N+ azide) or p-toluenesulfonyl (tosyl or Ts) azide, to provide either a zwitterionic phosphoramidate with N+ modification or a negatively charged phosphoramidate for Ts- modification in the DNA sequence. Incorporation of these N+ and Ts- modifications led to the formation of thermally stable parallel DNA triplexes, regardless of the number of modifications incorporated into the oligodeoxynucleotides (ONs). For both N+ and Ts- modified ONs, the antiparallel duplexes formed with complementary RNA were more stable than those formed with complementary DNA (except for ONs where the modification is in the middle of the sequence). Incorporation of N+ modifications led to the formation of duplexes whose thermal stability was less dependent on ionic strength than native DNA duplexes. Thermodynamic analysis of melting curves revealed that it is a reduction in unfavourable entropy, despite the decrease in favourable enthalpy, which is responsible for the stabilisation of duplexes with N+ modification.

N+ ONs also demonstrated greater resistance to nuclease digestion by snake venom phosphodiesterase I than the corresponding Ts-ONs. Cell permeability studies showed that Ts- ONs diffuse into the nucleus of mouse fibroblast NIH3T3 cells without the need for transfection reagents. In contrast, N+ ONs were concentrated in vesicles within the cytoplasm.

These results indicate that both N+ and Ts- modified ONs are promising for various in vivo applications.

Management of receivables and liabilities of the enterprise
Authors: YARMAK Olha , PROKUDIN Kyrylo
Published: December 2020

Introduction. For economic security and stability of the enterprise is an important topic of research and identification of ways to manage receivables and payables. A significant contribution to solving the problems of theoretical and practical aspects of receivables management of enterprises was made by such domestic scientists as O. Lishchenko, I. Sereda, О. Pustiak, Y. Demchenko, O. Rybalko, M Sychova, N. Sirenko, O. Smirnova et.al. However, the multifaceted nature of the problem requires further research on the theoretical and methodological foundations of ensuring the formation and functioning of an effective management system of receivables of the enterprise.
The purpose of the work is in the researching and studying the management system of receivables and payables at the enterprise.
Results. However, opinions on the direct organization of debt management of the enterprise are quite different. The model of receivables management, according to O. Lishchenko, I. Sereda, includes five elements. While O. Pustiak and Y. Demchenko believes that the algorithm for managing the company's calculations for goods, works and services includes as many as eight stages. Thus, according to O. Rybalko and M. Sychova, the receivables management algorithm should include seven stages. In turn, the model of accounts payable management according to N. Sirenko and O. Smirnova includes only three elements. However, as we can see from the above information, most authors forget that in the debt management system one of the important stages is their relationship with the basic goals and key performance indicators of enterprises, as well as with the conditions of business. In this case, if the consideration of the basic objectives in one way or another can still be found in the proposed algorithms for debt management of the enterprise, then taking into account the conditions of development of macro- and mesoenvironment of the enterprise is not carried out.
Conclusion. Thus, the development of management decisions to optimize the level of receivables and payables should be preceded not only by an analysis of the conditions of existence of the enterprise, but also an assessment of the level of manageability of the debt itself. At the same time, at high and medium levels of management, the company's management should use incentives to reduce the level of debt of the company, while at low and insufficient – mostly “heavy”.
Certain aspects of regulation of attorneys' behavior in social networks
Authors: STOROZHENKO Oleksandr , PROHOROVA Oksana
Published: December 2020

Introduction. Some aspects of a lawyer's behavior on social networks are regulated by the Rules of Attorney Ethics. However, these provisions have been criticized by lawyers since their adoption. Therefore, an analysis of the norms of those Rules is appropriate to address issues related to their application in practice.
The purpose of this paper is to Analyze the provisions of the Rules of Advocate Ethics in terms of regulating the behavior of a lawyer on social networks. Investigate the practice of applying such provisions as well as the possibility of further improving legal regulation in this area.
Results. The paper deals with the issues of regulation of lawyers' behavior in social networks, analyzes the norms of the Rules of Attorney ethics, examines potential negative consequences of application current version of those norms for both individual lawyers and for the whole institute of advocacy. Furthermore, it contains certain suggestions of how to improve legal regulation of this area. Emphasis on the existence of the unspecified concept of “lawyer's authority”. It is determined, that the interpretation of those concept is left to the discretion of the Qualification and Disciplinary Commission of the Advocacy. But such a wide competence may lead to committing some abuses by this authority. The problem of formation of additional duties of lawyers than those provided by the Rules of attorney ethics is revealed. The legitimacy of such responsibilities has been proven. The paper examines potential negative consequences of application current version of those norms for both individual lawyers and for the whole institute of advocacy. Namely, due to the lack of a clear possibility to identify the person leaving the record on the social network, it is considered to be difficult and sometimes impossible to prove the guilt of a particular lawyer. Furthermore, the paper contains certain suggestions of how to improve legal regulation of this area. In particular, the position of scholars on the impossibility of applying, according to lawyers on social networks, such disciplinary sanctions as suspension or termination of the right to practice law was supported. Authors consider it expedient to include information in the Unified Register of Lawyers of Ukraine to confirm the profile of a lawyer on a social network.
Conclusion. The necessity of developing a system of methodical recommendations for solving cases of this category is stated. It is proposed to develop methodological recommendations by analyzing the accounts of users of various social networks and summarizing the information obtained with the possible involvement of specialists in the field of IT-technologies.

The relevance of the work is due to the need to improve the efficiency of powder fire extinguishing systems. The aim of this work is to evaluate the effectiveness of the mechanism of heterogeneous inhibition of active flame centers by particles of fire extinguishing powder under non-stationary conditions of interaction. It was achieved by the method of theoretical modeling. There are obtained theoretical dependences of the reaction rate of heterogeneous inhibition of active flame centers by fire extinguishing powder particles on their dispersed and dynamic characteristics under non-stationary conditions of active particles interaction with the inhibitor surface. The efficiency of heterogeneous inhibition of active flame centers by fire extinguishing powder particles in a non-stationary mode of their interaction was evaluated. Fire fighting with fire extinguishing powder under non-stationary conditions is more effective the smaller the effective size of powder particles, the effective duration of the inhibition reaction and the longer the interaction time of powder particles with active flame centres. It was established that inhibition efficiency depends either on the kinetic parameters of active centers and disperse characteristics of the powder particles or on the ratio of interaction time of powder particles with the active centers as well as the characteristic duration of inhibition reaction. The results obtained allow optimizing the conditions and modes of fire extinguishing powder supply to the combustion zone in order to achieve the maximum effect of fire extinguishing.

Authors: Байков Андрей Владимирович , Александров Константин Валерьевич
Published: December 2020

Применение одного робототехнического средства (РТС) в зоне чрезвычайной ситуации (ЧС) малоэффективно из-за множества выполняемых задач, что обусловливает необходимость привлечения группы РТС для уменьшения времени ликвидации ЧС. В статье представлена математическая модель выбора группы РТС для ликвидации ЧС. Разработанная модель комплексной оценки эффективности проведения аварийно-спасательных работ при групповом применении РТС в техногенной ЧС является научно-методическим аппаратом по обоснованию состава группировки системы РТС МЧС России, необходимых для выполнения задач в ЧС.

The use of one robotic in the emergency zone is not very effective due to the multitude of tasks performed in the emergency zone. This determines the need to use the group of robotics to reduce the time for emergency elimination. The relevance of the work is determined by the scattered scientific and methodological system for substantiating the composition of the robotics grouping of the Ministry of Emergency Situations of Russia, as well as by errors in decision making on the use of robotics in emergencies. The paper presents a mathematical model for choosing a group of robotic equipment for emergency response. The model for integrated assessment of the rescue operation effectiveness with application of group of robotics is based on the “scheduling theory”. The paper proposes scientific methods for the development of quantitatively substantiated recommendations for decision-making, where mathematical models of ordering various purposeful actions in time are constructed and analyzed taking into account the objective function and different restrictions. The developed model for integrated assessment of the effectiveness of emergency rescue operations at group application of robotics during technogenic emergency is a scientific and methodological approach for substantiating the structure of robotics grouping of EMERCOM of Russia required to solve tasks in an emergency.

Authors: Faustorilla John Francis
Published: December 2020

Nursing informatics, despite its rich evolution and dynamic nature remains an emerging field in the Philippines. With its inclusion as a critical content in the Bachelor of Science in Nursing Curriculum, Policies, and Standards in 2008, various interpretations and adaptations were made evident thereby influencing Philippine Nursing. Critical discussions, whether or not Nursing Informatics affect the focus of nursing with the integration of information and communication technologies into nursing service delivery systems continue to exist. It is imperative that better understanding of the contributions of Nursing Informatics on Philippine Nursing from a historical perspective and declaring its implications for Philippine Nursing Practice initiated within a Caring viewpoint are addressed and illuminated. This paper aims to provide a description of the initiation of Nursing Informatics in the hope of establishing its ontological and epistemological position while providing a clearer understanding of its historical developments and influences on Philippine Nursing initiated within a caring perspective in a highly technological world.
