The INTERSECTION Framework: Applied Security for Heterogeneous Networks
Authors: Flizikowski Adam , Majewski Mateusz , Hołubowicz Maria , Kowalczyk Zbigniew , Romano Simon Pietro
Published: April 2024

Inherent heterogeneity of the networks increases risk factor and new security threats emerge due to the variety of network types and their vulnerabilities. This paper presents an example of applied security framework – the INTERSECTION. By referring to the ISO/IEC security standards and to the FP7 INTERSECTION project results, authors underline that in the processes of managing and planning security, investigating technology and business governance should be at least as important as formalizing the need for decisions on security cooperation between operators. INTERSECTION provides security mechanisms and introduces capability possible only with a management solution that is at a higher level than that of any of the connected systems alone.
Tunneling Activities Detection Using Machine Learning Techniques
Authors: Allard Fabien , Dubois Renaud , Gompel Paul , Morel Mathieu
Published: April 2024

Tunnel establishment, like HTTPS tunnel or related ones, between a computer protected by a security gateway and a remote server located outside the protected network is the most effective way to bypass the network security policy. Indeed, a permitted protocol can be used to embed a forbidden one until the remote server. Therefore, if the resulting information flow is ciphered, security standard tools such as application level gateways (ALG), firewalls, intrusion detection system (IDS), do not detect this violation. In this paper, we describe a statistical analysis of ciphered flows that allows detection of the carried inner protocol. Regarding the deployed security policy, this technology could be added in security tools to detect forbidden protocols usages. In the defence domain, this technology could help preventing information leaks through side channels. At the end of this article, we present a tunnel detection tool architecture and the results obtained with our approach on a public database containing real data flows.

Authors: Jasiul Bartosz , Śliwa Joanna , Piotrowski Rafał , Goniacz Robert
Published: April 2024

The problem of user authentication and authorization is usually being solved in a single system. Federated environment assumes heterogeneity of systems, which brings the problem of mutual users and services authentication and authorization. In this article the authors presented security requirements for cross domain information exchange in federated environments and a method of secure access to information resources on the basis of web services. Special attentionwas paid to authentication and authorization of users and services. As opportunities, there were presented solutions verified in multinational experimentations and exercises.
Adaptation of the Kademila Routing for Tactical Networks
Authors: Ginzler Tobias , Amanowicz Marek
Published: April 2024

n this paper a modification of the widely used Kademlia peer-to-peer system to tactical networks is proposed. We first take a look at the Iavailable systems today to cover the range of possibilities peer-to-peer systems offer. We identify candidates for use in military networks. Then we compare two candidate systems in an environment with highly dynamic participants. The considered environment is focused on the special conditions in tactical networks. Then we give rationale for choosing Kademlia as a suitable system for tactical environments. Since Kademlia is not adapted to military networks, a modification to this system is proposed to adapt it to the special conditions encountered in this environment. We show that optimizations in the routing may lead to faster lookups by measuring the modified algorithm in a simulation of the target environment. We show also that the proposed modification can be used to extend the battery lifetime of mobile peer-to-peer nodes. Our results show that peer-to-peer systems can be used in military networks to increase their robustness. The modifications proposed to Kademlia adapt the system to the special challenges of military tactical networks.

On Testing IPv6 in Small ISP’s Networks
Authors: Sienkiewicz Konrad , Gajewski Mariusz , Batalla Jordi Mongay
Published: April 2024

Testing process allows to detect potential faults of implementation of IPv6 in the phase preceding migration, thus minimizing the risk of problems in IPv6 deployment. In general the IPv6 tests should be performed by all network providers, however the test range should fit their needs. It causes that test range for small network operators (offering basic set of services) could be limited in comparison to larger ISPs. In this paper, we propose an approach to IPv6 tests with regard to IPv6 deployment by small operators. We present tools and specifications for IPv6 tests and propose a test platform optimized to small ISP’s needs. The test platform is a dedicated LiveCD distribution based on FreeBSD operating system with IPv6 test environment and set of pre-defined tests. An advantage of this solution is the ability to launch the test tool software on any computer equipped with an Ethernet card and CD-ROM/DVD-ROM drive. LiveCD test tool allows users to execute tests and analyze the results in graphical environment.We believe that this approach will help to simplify and shorten the IPv6 testing process in small ISP’s networks.
GPON, the Ultimate Pertinent of Next Generation Triple-play Bandwidth Resolution
Authors: Sultan D. M. S. , Arefin Md. Taslim
Published: April 2024

Optical transmission is getting more popular in the access network due to the increasing demand for bandwidth. New services like IP television (IPTV) transmission, video on demand (VoD) etc. over Internet together along high speed Internet access are confronting the demand of higher bandwidth at the customer end in today’s Ethernet network backbone. Even though today’s well deployed XDSL (i.e., VDSL/VDSL2+, SHDSL) solutions can satisfy bandwidth demand but are limited to the restriction regarding distance. Hereby, the suitable solution for high bandwidth demand with a long reach can be met by reaching optical cable to cus- tomer end directly. One of the possible ways would be to install passive optical network (PON). Gigabit PON (GPON) is the far-most advanced PON solution used by European and US providers while providers in Asia predominantly use EPON/GePON. This GPON is the basic technology to support the structure of the next-generation fiber to the home (FTTH) system. This paper provides an overview of such GPON solution associating its network architecture, transmission mechanisms and some key services.
Developing a Secure Image Steganographic System Using TPVD Adaptive LSB Matching Revisited Algorithm for Maximizing the Embedding Rate
Authors: Kumar P. Mohan , Hanmuganathan K. L.
Published: April 2024

Steganography is the approach for hiding any secret message in a variety of multimedia carriers like images, audio or video files. Whenever we are hiding a data, it is very important to make it invisible, so that it could be protected. A number of steganographic algorithms have been proposed based on this property of a steganographic system. This paper concentrates on integrating Tri way pixel value differencing approach and LSB matching revisited. The secret data embedded in images were images, text and audio signals so far. The proposed scheme has also come with the executable file as secret data. Also, the experimentation results show that, the important properties of a steganographic system such as imperceptibility, capacity of the carrier image and also resistance against the various steganalytic tools have also been achieved with this stego-system.
QoS Conditions for VoIP and VoD
Authors: Dymarski Przemysław , Kula Sławomir , Huy Thanh Nguyen
Published: April 2024

This paper concerns quality evaluation of the telecommunication services: VoIP (representing the RT interactive class) and VoD (representing the MM streaming class). Subjective and objective methods and tools for perceived quality measurement are analyzed and compared. Subjective tests are performed for selected video sequences using the Double-Stimulus Impairment Scale (DSIS) method. Thus the objective algorithms (VQM and VQmon) are calibrated. Speech quality is measured using the objective methods: PESQ and POLQA. Threshold values for network parameters (packet loss rate, delay jitter) are set, that guarantee the acceptable service quality.
Active – Passive: On Preconceptions of Testing
Authors: Brzeziński Krzysztof M.
Published: April 2024

In telecommunications and software engineering, testing is normally understood to be essentially active: a tester is said to stimulate, control, and enforce. Passive testing does not fit this paradigm and thus remains the niche research subject, which bears on the scope and depth of the obtained results. It is argued that such limited understanding of testing is one of its many community-bound preconceptions. It may be acceptable in the current engineering approach to testing, but can and should be challenged in order to converge on the core concepts of the proposed science of testing (“testology”). This methodological work aims at establishing that there are no fundamental reasons for admitting the dominant role of the active element in testing. To show this, external (also extratechnical) areas are consulted for insight, direct observations, and metaphors. The troublesome distinction between (passive) testing and monitoring, as well as unclear relations between testing and measurements, are also addressed.

Designing Auctions: A Historical Perspective
Authors: Karpowicz Michał
Published: April 2024

Auction is a form of organization of competition that leads to the assignment and valuation of resources based on the information obtained from the competing agents. From the perspective of systems science it is a distributed resource allocation algorithm applied in the environment with information asymmetry, i.e., where the interconnected and interacting subsystems have different information about the system as a whole. This paper presents an overview of the historical development of mathematical theory underlying modern approach to auction design. Selected practical applications of the theory are also discussed.

Improving Population-Based Algorithms with Fitness Deterioration
Authors: Wolny Adrian , Schaefer Robert
Published: April 2024

This work presents a new hybrid approach for supporting sequential niching strategies called Cluster Supported Fitness Deterioration (CSFD). Sequential niching is one of the most promising evolutionary strategies for analyzing multimodal global optimization problems in the continuous domains embedded in the vector metric spaces. In each iteration CSFD performs the clustering of the random sample by OPTICS algorithm and then deteriorates the fitness on the area occupied by clusters. The selection pressure pushes away the next-step sample (population) from the basins of attraction of minimizers already recognized, speeding up finding the new ones. The main advantages of CSFD are low memory an computational complexity even in case of large dimensional problems and high accuracy of deterioration obtained by the flexible cluster definition delivered by OPTICS. The paper contains the broad discussion of niching strategies, detailed definition of CSFD and the series of the simple comparative tests.
Incrementally Solving Nonlinear Regression Tasks Using IBHM Algorithm
Authors: Zawistowski Paweł , Arabas Jarosław
Published: April 2024

This paper considers the black-box approximation problem where the goal is to create a regression model using only empirical data without incorporating knowledge about the character of nonlinearity of the approximated function. This paper reports on ongoing work on a nonlinear regression methodology called IBHM which builds a model being a combination of weighted nonlinear components. The construction process is iterative and is based on correlation analysis. Due to its iterative nature, the methodology does not require a priori assumptions about the final model structure which greatly simplifies its usage. Correlation based learning becomes ineffective when the dynamics of the approximated function is too high. In this paper we introduce weighted correlation coefficients into the learning process. These coefficients work as a kind of a local filter and help overcome the problem. Proof of concept experiments are discussed to show
Trends and Differences of Applying Intelligence to an Agent
Authors: Elmahalawy Ahmed M. , Ali Moukhtar A. , Harb Hany M.
Published: April 2024

The agent technology has recently become one of the most vibrant and fastest growing areas in information technology. On of the most promising characteristics of agent is its intelligence. Intelligent agent is the agent that percepts its environment, collects all information about its environment that it needs, processes these information and then generate proper actions according to these information. This paper discusses trends and differences between two main types of intelligence that can be applied to agent: accumulative intelligence and dynamic intelligence. Accumulative intelligence is discussed with its two perspectives: moment perspective and historical perspective. Auto-vehicle driver is also discussed as an application example of accumulative intelligence. Also, MOSAIC, Mimesis, and MINDY models are reviewed as the pioneering works of dynamic intelligence.
VEGF, HIF-1α, and Metabolic Indicators in Esophageal Squamous Cell Carcinoma
Authors: Chen Yangyan
Published: April 2024

Objective: To explore and analyze the expression and clinical significance of vascular endothelial growth factor (VEGF), hypoxia-inducible factor 1α (HIF-1α), and metabolic indicators in esophageal squamous cell carcinoma (ESCC). Methods: Sixty ESCC patients admitted to the hospital from October 2021 to October 2023 were selected as the ESCC group. Sixty normal healthy patients from the same period were chosen as the control group. Their serum samples and tissue samples were collected. Metabolic indicators of all study subjects were obtained based on the basic biochemical results upon admission. RT-PCR was utilized to detect the expression of VEGF and HIF-1α in ESCC tissues. Results: The expression of VEGF and HIF-1α in the ESCC T3+T4 group was significantly higher than that of the carcinoma in situ (Tis) group, T1+T2 group, and control group. Furthermore, the expression of HIF-1α was found to be related to the expression of VEGF, showing a significant correlation between the quantities. Significant differences in the levels of metabolic indicators were observed between the ESCC group and the control group (P < 0.05). Conclusion: Metabolic indicators are associated with the onset of ESCC in patients. Abnormal lipid metabolism plays a crucial role in the occurrence and development of tumors. The expression of VEGF and HIF-1α in ESCC tissues significantly correlates with the tumor stage, providing a new reference for the diagnosis and treatment of ESCC.

Authors: Chen Bo , Shi Donghong , Ai Min , Zhang Longjiang
Published: April 2024

Objective: To analyze the effect of arterial embolism (AE) in patients with massive urinary system bleeding (MBUS). Methods: From September 2018 to September 2023, 175 cases of MBUS patients in the emergency department of the hospital were randomly selected and divided into groups according to the length of stay. Among them, 85 cases (September 2018 – September 2020) underwent bladder irrigation treatment with aluminum potassium sulfate solution through a catheter (Group A), and 90 cases (October 2020 – September 2023) underwent AE treatment (Group B). The treatment effects of the two groups were compared. Results: The treatment effectiveness of Group B is higher than that of Group A (P < 0.05). The urinary hemoglobin level of Group B is lower than that of Group A at 1, 6, 12, and 24 hours after treatment (P < 0.05). Among the 90 cases treated with AE, 7 cases had a fever, with body temperatures ranging from 37.3°C to 38.9℃, with a mean temperature of 38.2 ± 0.3℃. Four cases experienced local pain, nausea, and vomiting, while two cases of intra-iliac AE showed transient buttock pain. These patients with adverse reactions were treated symptomatically for 7 days. All patients recovered after treatment. Intravenous urography of 87 patients in June showed that the renal pelvis and calyces were in good condition, the renal function returned to normal, and the blood urea nitrogen and blood creatinine test results were within the normal range. After 1 year of follow-up, no hypertension occurred. Conclusion: AE treats MBUS patients in the emergency department with remarkable efficacy. It has the advantages of less damage to the body, rapid hemostasis, high safety, and maximum preservation of organ function.

Authors: Sommer Julian , Reiter Hannah , Sattler Janko , Cacace Elisabetta , Eisfeld Jessica , Gatermann Sören , Hamprecht Axel , Göttig Stephan
Published: April 2024

Background

Carbapenemase-producing Enterobacterales are a public health threat worldwide and OXA-48 is the most prevalent carbapenemase in Germany and western Europe. However, the molecular epidemiology of OXA-48 in species other than Escherichia coli and Klebsiella pneumoniae remains poorly understood.

Aim

To analyse the molecular epidemiology of OXA-48 and OXA-48-like carbapenemases in Citrobacter species (spp.) in Germany between 2011 and 2022.

Methods

Data of 26,822 Enterobacterales isolates sent to the National Reference Centre (NRC) for Gram-negative bacteria were evaluated. Ninety-one Citrobacter isolates from 40 German hospitals harbouring bla
OXA-48/OXA-48‑like were analysed by whole genome sequencing and conjugation experiments.

Results

The frequency of OXA-48 in Citrobacter freundii (CF) has increased steadily since 2011 and is now the most prevalent carbapenemase in this species in Germany. Among 91 in-depth analysed Citrobacter spp. isolates, CF (n = 73) and C. koseri (n = 8) were the most common species and OXA-48 was the most common variant (n = 77), followed by OXA-162 (n = 11) and OXA‑181 (n = 3). Forty percent of the isolates belonged to only two sequence types (ST19 and ST22), while most other STs were singletons. The plasmids harbouring bla
OXA‑48 and bla
OXA-162 belonged to the plasmid types IncL (n = 85) or IncF (n = 3), and plasmids harbouring bla
OXA‑181 to IncX3 (n = 3). Three IncL plasmid clusters (57/85 IncL plasmids) were identified, which were highly transferable in contrast to sporadic plasmids.

Conclusion

In CF in Germany, OXA-48 is the predominant carbapenemase. Dissemination is likely due to distinct highly transmissible plasmids harbouring bla
OXA‑48 or bla
OXA-48-like and the spread of the high-risk clonal lineages ST19 and ST22.

Indigenous Resilience in Illustration
Authors: Brown B. Kenneth
Published: April 2024

This Place: 150 Years Retold (edited by Ryan Howe and Jen Storm) marks a watershed moment in the portrayal of Indigenous histories in Canada. As a graphic novel anthology crafted by Indigenous creators, it turns the page on settler-centred narratives and restores narrative sovereignty. The stories offer an emotional journey through the past century and a half, exploring the resilience and resistance of communities that have endured a post-apocalyptic existence since the era of Contact. Readers bear witness to Indigenous imagination, psychic confrontations with the lingering impacts of genocide, and profound reflections on the nature of time and existence. This paper argues that, within the anthology, the story "Nimkii" stands out, offering a poignant representation of the resilience of Indigenous communities amidst the devastating historical event of the Sixties Scoop. Crafted by the writing of Kateri Akiwenzie-Damm and the artwork of Ryan Howe and Jen Storm, “Nimkii”’s narrative is a testament to the indomitable spirit of Indigenous Peoples, their deeply rooted connections to one another, and their fight to heal the enduring scars of colonial oppression. This paper offers an analysis of “Nimki”’s testimony, and closes by reflecting on the story’s potential impacts on an Indigenous reader.
Institutional Rhetorical Genres
Authors: Krzpiet Victoria
Published: April 2024

This paper introduces the idea of rhetorical genre, drawing on previous research in rhetorical genre theory to explain how the genres used in institutions affect the personal and professional lives of people who use them, and how they naturalize certain ideologies in those institutional settings. The paper lays out how—while rhetorical genres serve many practical purposes—they also affect power relations within an institution and can compromise the identity of the individual using them. When assessing the efficacy of these genres, this paper remarks, it is important to question how they were constructed and for whom. To further explore this topic, the paper recounts the personal experience relayed in previous research by Anthony Paré, in which he taught a professional writing course to female Inuit social workers.
One Territory, Two Worlds
Authors: Gardiner Luke
Published: April 2024

This paper analyzes Kazuo Ishiguro’s When We Were Orphans is a literary work that critiques and examines colonial structures and their consequences: Ishiguro criticizes the colonization of Shanghai by showing the inherent power imbalance between the native population and the colonizers, the chaos and lawlessness outside of the Settlement as opposed to within, and the general understanding of Shanghai and the Settlement held by characters from Britain. As a work of historical fiction, the novel serves to explore a particular society at a particular point in time, and therefore, must be analyzed with close consideration to the historical period and context in which the novel is set. At the same time, this paper concludes, Ishiguro’s observations and critiques are highly relevant in today’s society.

Published: April 2024

The purpose of the study is to analyze research publications on sexual dysfunction, modern possibilities of diagnosis and treatment of this condition in women with neurological diseases. Material and methods. The search for literary sources was carried out in the electronic databases PubMed Central, MEDLINE, Science Direct, Cochrane Library in the period from 2000 to 2023. Conclusions. Sexual dysfunction (SD) is a fairly common problem affecting on average about 60% of female patients suffering from various neurological diseases. The presence of SD significantly impairs physical, psychological and social parameters of women's health. The number of studies dealing with the problem of SD is quite limited. It should be noted that the development of differentiated comprehensive rehabilitation programs for patients with SD is a qualitatively new approach and is potentially effective in the management of SD. However, there is currently insufficient data for the application of complex methods of recovery and treatment of SD, which implies further study of the effectiveness of various methods of correction of SD in clinical trials.

Introdução: Meningiomas são causados pela multiplicação anormal de
células da membrana aracnoide. Essas neoplasias constituem 2% de todos
os meningiomas intracranianos, conhecidos por crescimento e invasão local agressiva e potencial para metástase. Esses tumores têm capacidade de
infiltrar-se nos tecidos circundantes, comprometendo a função cerebral. Objetivo: Caracterizar o perfil epidemiológico de meningiomas em
adultos na região Nordeste no período de 2018 a 2022. Métodos: Estudo
epidemiológico, transversal, descritivo e quantitativo. Os dados foram obtidos do Departamento de Informática do Sistema Único de Saúde (DATASUS).
As variáveis consideradas foram: sexo, faixa etária, Unidade Federativa de
residência e modalidade terapêutica. Foi dispensada a apreciação pelo Comitê de Ética em Pesquisa por serem dados públicos. Resultados: No período
de janeiro de 2018 a setembro de 2022, observou-se 87 casos de neoplasia
das meninges em adultos no Nordeste. Quanto ao sexo, o feminino liderou
(71%). Na faixa etária, predominou-se pessoas com 45 a 54 anos (43,04%).
Considerando UF de residência, percebeu-se a maioria das notificações dos
casos na Bahia (37,39%). Na modalidade terapêutica, 69,62% dos casos não
possuem informações, e entre os registrados, a radioterapia se destacou
(18,99%). Conclusão: Verificou-se prevalência de casos no sexo feminino, na
faixa etária de 45 a 54 anos e no estado da Bahia. Ressalta-se que há escassez
de dados acerca das modalidades terapêuticas no Nordeste. A ausência de
notificação de tratamento representa um cenário que merece atenção na
saúde pública, visando consolidar as informações para que melhor se promova a oferta de recursos terapêuticos

A cárie um processo complexo que envolve a desmineralização e destruição dos tecidos duros do dente, como esmalte, dentina e cemento. Os microrganismos presentes no biofilme dental metabolizam açúcares e carboidratos e secretam ácidos como subproduto. O ácido erode gradativamente os minerais do esmalte, levando à sua desmineralização. Este processo enfraquece a estrutura do dente e cria pequenos poros são lesões incipientes na superfície do esmalte esse processo ocorre e é equilibrado pela capacidade tampão da saliva e dos fluoretos. Diante deste contexto, o controle das lesões consiste em remoção do biofilme e o equilíbrio nas reações de desmineralização e remineralização. O processo de remineralização ocorre naturalmente através de minerais presentes na saliva, que devolvem os minerais perdidos durante a desmineralização. Com o advento de inúmeras tecnologias e novas abordagens para incorporação de partículas bioativas no compósito restaurador dental é necessários estudos que investiguem e compare as características e o comportamento destes. As partículas bioativas apresentam características interessantes para a prevenção da desmineralização dos tecidos dentais e um efeito de proteção da interface restauradora através da liberação de íons e efeito de recarga. Esse trabalho teve como objetivo revisar a literatura em relação às características de compósitos resinosos contendo partículas bioativas.

Caregivers of Children Living with HIV/AIDS experience severe burdens in Africa amidst unmet needs while seeking care from hospitals. This study aimed to explore the diagnosis history, health-seeking behaviour, and care provided by hospitals and whether the services meet caregivers’ expectations. We used a qualitative approach and conducted individual in-depth interviews among purposively sampled caregivers of children living with HIV/AIDS from three hospitals. We achieved data sufficiency after interviewing nine participants. Audio-recorded interviews were transcribed verbatim and thematically analyzed manually through Collaizi’s steps. Four themes developed including; history of pregnancy and poor HIV testing, effective care for caregivers and CLWH, attitude of healthcare providers, and unmet expectations of care. Healthcare providers showed positive attitudes towards caregivers and provided services (counselling, dispensing Anti-retrovirals, health monitoring, and coordination of clinical care). Expectations bordered on financial support (for food, education, health care), and treatment for opportunistic infections. Findings indicate gaps in HIV voluntary testing for pregnant women, enrollment in Prevention of Mother to Child Transmission (PMTCT), and unmet needs. It is imperative to improve coverage of testing for pregnant women and efforts made to meet their needs. Financial support, provision of food security, and assistance for caregivers are essential for care.
La huelga de Horcones 2007: el asesinato de Rodrigo Cisterna como pervivencia de la Doctrina de la Seguridad Nacional
Authors: Alegría Herrera Rogelio Fernando
Published: April 2024

Este artículo se propone analizar la persistencia de prácticas arraigadas en la dictadura cívico-militar chilena, las cuales delinean una particular dinámica en la relación entre el Estado y la población en contextos de tensión social, especialmente durante manifestaciones. A través de estudio de caso centrado en la huelga de obreros forestales en Horcones durante el año 2007, en la que falleció Rodrigo Cisterna Fernández y otros trabajadores resultaron heridos a manos de carabineros, se busca reconstruir los acontecimientos. El análisis se fundamenta principalmente en los documentos judiciales asociados al caso, desentrañando los argumentos presentados por la Justicia Militar para legitimar las acciones institucionales. Estos argumentos revelan una visión persistente en la que el Estado defiende a sí mismo frente a la ciudadanía, denotando la continuidad de la Doctrina de Seguridad Nacional (DSN) en la estructura institucional. El presente estudio busca contribuir a la comprensión de las complejas interacciones entre el Estado y la sociedad civil en momentos de tensión, promoviendo una reflexión sobre la necesidad de reformas institucionales que fomenten una relación más equitativa y respetuosa de los Derechos Humanos.
