Advancing Face Recognition Technologies: The Role of Decision Trees in Classifying Complex Image Pairs
Authors: Kakula Francis , Mbelwa Jimmy , Maziku Hellen
Published: September 2024

The advancement of face recognition technologies has been pivotal in various applications, from security systems to personalized user experiences. There are significant efforts already devoted to solving challenges of multimodality and pose variation in face recognition. Some studies focus on multimodality but pose-invariant, and other studies focus on pose variation but single modality. Despite significant progress, various face recognition algorithms do not consider both multimodality and pose variation constraints in their proposed methods. Recognizing face images presented both in a different modality and in a different pose presents serious challenges to current algorithms. This paper proposes an algorithm that combines the strengths of deep learning with decision trees to improve face recognition performance across modalities and poses in constrained and unconstrained environments. This hybrid approach leverages the representational power of deep learning and the interpretability and simplicity of decision trees. The findings indicate significant improvements over existing methodologies, particularly in challenging conditions like when multimodality and pose variation constraints are compounded together in the input face images in both constrained and unconstrained environments. The proposed algorithm not only addresses the limitations of current face recognition systems but also offers scalable, efficient solutions suitable for real-world applications.

Published: September 2024

In the communal lands and rural communities of Mexico, forest tourism is emerging as a possibility to diversify productive activities for communal land members, as an alternative to poverty and marginalization. In this research, community forestry tourism is considered as an alternative use of the territory and its resources, both by those who provide the service and by the users, since it implies practices of environmental valuation in situ, recognition of the cultural heritage of the communities and their interaction with them. The aim of this study was to identify and evaluate the potential of community forestry tourism in order to propose a local development strategy for the communal land El Terrero, considering its natural, social and cultural resources. The methodology used was based on Action-Research, considering a holistic research approach, capable of encompassing several dimensions and functions, oriented to analyze each element-dimension in its specific context and to individualize its peculiar combination with the other elements-dimensions. The results showed that the communal land El Terrero has an excellent tourism potential and the communal land members are interested in participating in tourism activities, which represents a development opportunity for the inhabitants of these areas. A very important activity in the communal land is the production of slabs and clay handicrafts, helping as an alternative of entry in the community. In this sense, it is possible to benefit from the current advantages of the new tourist client, who seeks new experiences and motivations, such as the obsession with the search for happy and healthy lifestyles, and the growing awareness of nature and natural things. However, it is necessary to create tourist routes, strengthen the communal land organizational capacity, promote care for the environment and enhance the communal land virtues to attract a tourist demand interested in the relationship with the forest.

Published: September 2024

Pigeons harbour and spread numerous zoonotic diseases, including bacterial diseases caused by pathogenic bacterial communities. Pigeons are the hosts for various bacteria, including Escherichia coli, Pseudomonas aeruginosa, Klebsiella pneumoniae, Staphylococcus aureus, and Streptococcus pyogenes. In the present study, pigeon (Columba livia) from farms and houses were subjected to determine the major causative bacterial pathogens. The samples were collected from the oral cavity, cloaca and ocular regions of pigeons. The distribution of bacteria was tested using the plate count agar method, and virulence bacteria were further isolated using a selective agar base. Among the three different sources, cloaca harbours a higher (54) bacteria (p<0.05) than other sources. The prevalence of common bacterial pathogens among pigeon samples was analyzed. Among the characterized bacterial species (E. coli, P. aeruginosa, K. pneumoniae, S. aureus, and S. pyogenes), E. coli was predominant in almost all selected samples, especially cloaca samples. The isolates were characterized based on their growth in selective media, biochemical properties and 16S rDNA gene sequencing.

Blockchain-based data governance for privacy-preserving in multi-stakeholder settings
Authors: Garcia Rodrigo Dutra , Ueyama Jó
Published: September 2024

In multi-stakeholder systems such as healthcare, the Internet of Things, and supply chain management, data is often generated and shared. As a result, data owners aim to maintain control and privacy over their data, while data consumers need reliable methods to verify the data’s origins and creators. These conflicting interests require data governance systems to ensure data provenance, privacy protection, consent management, and selective disclosure. To address these challenges, this research proposed a decentralized data governance system that utilizes blockchain technology, proxy re-encryption (PRE), and Boneh, Boyen, and Shacham (BBS) signatures. The proposed system enables data owners to control, selectively share, and track their data through privacy protection, consent management, and selective disclosure mechanisms. It also allows data consumers to understand the data’s lineage through a blockchain-based provenance mechanism. The research focused on analyzing electronic prescription use cases that contain sensitive data and involve multiple stakeholders, such as patients, doctors, and pharmacists. The research was structured as a collection of published articles organized in the following sequence: problem formulation and developing smart contracts, implementing privacy and consent management through PRE, and applying BBS signatures for selective data sharing. The proof-of-concept implementation and evaluations were conducted using CosmWasm, Hyperledger Besu, Ethereum, pyUmbral PRE, and BBS signatures. The evaluations show that the proposed decentralized system is platform-agnostic, scalable, and capable of providing higher transparency, privacy, and trust, all with minimal overhead.

Published: September 2024

Payment-channel networks (PCN) represent the leading solution to scale blockchain-based payments to the performance levels of centralized payment systems. However, current PCNs require nodes to stay permanently online and have enough resources to execute payment security mechanisms. Such assumptions are difficult to guarantee in battery-powered devices with intermittent connectivity patterns, such as mobile phones, smart objects, and sensors. In this thesis, we address the case of PCNs with resource-constrained devices on several fronts. First, we formalize a hybrid PCN model that considers light nodes and propose a mechanism to protect payment channels with resource-constrained devices. Our experiments show that the proposed mechanism is efficient for devices with high and medium availability in mobile broadband connections. Next, we propose PCNsim, a simulator that replicates the main functionalities of a PCN in the OMNeT++ framework. PCNsim allows researchers to experiment with payments under custom networking conditions representing resource-constrained devices’ connections. PCNsim’s demonstrations show that it correctly reproduces the behavior of a PCN over unreliable communication channels. Finally, we address the problem of routing payments from resource-constrained devices. We present a payment scheme that anticipates payment confirmations for time-sensitive applications and two routing algorithms that route payments considering application-specific constraints. The results show that our routing algorithms are efficient both for single-path and multi-path payments and reach their top performance when the problem’s constraints are tight.

Schicksalstage in Madrid: Zur olympischen Renaissance des Handballs
Authors: Eggers Erik
Published: September 2024

After its premiere at the 1936 Olympic Games in Berlin, Handball was no longer part of the Olympic Program after the Second World War. This was due to the handball’s image as a “Nazisport” and its lack of popularity outside of Europe. The members of the International Olympic Committee (IOC) were convinced to bring it back by the establishment of the United States Team Handball Association (USTHF) – and even more so by two exhibitions at the 63rd IOC Session in Madrid 1965, in which the two teams involved, host Spain and the Federal Republic Germany, at the request of International Handball Federation, simulated equal strength.

Authors: Krüger Michael
Published: September 2024

The idea of peace in sport dates back to Pierre de Coubertin and the founding of the Olympic Games in modern times. It has been reaffirmed ever since and can be found in the current version of the Olympic Charter. According to the charter, Olympic sport should contribute to the creation of a “peaceful society”. The article systematically discusses the specific concept of peace in (Olympic) sport and also analyses the changes it has undergone historically. The specificity of the concept of peace in Olympic sport is that it is based on strength and competition. The agonistic nature of sport is the basis for peace and fairness. Peace in and through sport is only possible in freedom.

Background: The rehabilitation of the atrophic maxilla with zygomatic implants appears to be a complex challenge as this surgery is not without complications. For this reason, the operator approaching it must be aware of the possible surgical complications.
The aim of this study was firstly to assess the incidence of complications following zygomatic implant operations performed using the intrasinus technique and to compare the data obtained with the results already present in the literature.
Materials And Methods: The methods chosen for the evaluation of implant success were those reported in the article by Chrcanovic et al which refers to factors such as implant survival rate, percentage of failed implants and,incidence of post-operative complications. A total of 174 implants were included in the study.
The study comprised three phases:
Phase 1
-collection of the personal, anamnestic, clinical and radiological data of each patient participating in the study
-detection of the number of zygomatic implants, the number of failed implants and any post- operative complications resulting from the intrasinus technique and subsequent comparison with data reported in the literature.
Phase 2
-comparison of complications arising with intrasinusal and extrasinusal technique
Phase 3
-administration of the satisfaction questionnaire of patients treated with the extrasinusal technique.
Results: Complications occurred in 14 patients and the most frequent complication was sinusitis, followed by soft tissue infections, 3 implants failed. Specifically, the most frequent complication related to intrasinusal technique surgery is sinusitis, caused by invasion of the Higmoro antrum by the implant.
Frequency analysis of the patient questionnaire shows high satisfaction with implant-prosthetic rehabilitation with zygomatic implants. Patients appear very satisfied with the aesthetics and functionality provided by the rehabilitation.
Conclusion: Zygomatic implants allow the fixed rehabilitation of patients with severe upper jaw atrophies, and although complications may occur, patient satisfaction was very high as it allows them to fully recover aesthetics and function, facilitating a rapid return to social life.

Authors: Bondarchuk Olena
Published: September 2024

The article analyzes the peculiarities of the relationship between teenagers' experiences of parent-child relationships and the level of meaningfulness of their lives. The relevance of the research is substantiated, due to the expediency of researching parent-child relationships as an important factor in adolescents' meaningfulness of life, and, as a result, their ability to consciously experience and self-regulate negative and psychotraumatic mental states. An analysis of the results of an empirical study of the attitude of teenagers to their parents and to the family as a whole is presented, according to which, in particular, it was established that a significant number of teenagers show a positive attitude towards their mother and an ambivalent attitude towards their father. It is shown that, in general, the peculiarities of the mother's attitude towards teenagers are more vividly experienced by them than the father's attitude towards them. At the same time, the data analysis shows a certain inconsistency in the perceptions of teenagers about the attitude of their parents – positive interest and autonomy, on the one hand, and directiveness and inconsistency, on the other hand, for a fairly significant number of the studied. The results of the study of the levels of meaningfulness of life by teenagers are presented, the analysis of which allowed us to ascertain the presence of a low level in more than half of the subjects, while only one in six teenagers had a high level. At the same time, statistically significant differences were found in the peculiarities of teenagers' experience of their parents' attitude towards them, depending on the level of their awareness of the meaning of life. In particular, it is about the existence of a direct, statistically significant relationship between the adolescent's perceptions of the level of positive interest from the mother and father and the level of their meaningfulness of life. In contrast, the relationship was reversed for perceptions of both maternal and paternal inconsistency, maternal hostility, and parental directiveness. It was established that such results, taking into account the low level of meaningfulness of life characteristic of almost half of the researched, testify to the presence of a significant part of teenagers in difficult life circumstances and, accordingly, in the risk zone in the context of successfully overcoming psycho-traumatic situations in the conditions of war.

Published: September 2024

The article is devoted to highlighting the psychological features of the ability of specialists in socio-economic professions to prevent and cope with information stress and building a theoretical model on this basis. The current state of research on the emergence of stressful conditions, including information stress, is analyzed. The information stress is defined as a reaction to the violation of information and cognitive processes of activity regulation as a result of information influence. The classification of information stress according to the content of information influence is outlined: related to information overload; to the interaction of a person with information technologies; to situations of an informational nature in professional activity. The ability to prevent and cope with information stress is considered as a property of the psyche to ensure adaptation to stress factors of an informational nature, to harmonize various aspects of life in difficult conditions of influence of destructive information flows, to show internal activity in preserving and restoring its own resources, to maintain the balance of the value and meaning sphere. A theoretical model of the ability to prevent and cope with information stress of specialists in socio-economic professions is presented, which includes four components: value-motivational, cognitive-reflective, emotional-evaluative, conative-regulatory, and relevant criteria and indicators. It has been determined that the value-motivational component is represented by a set of motives and values that encourage a specialist to prevent and overcome information stress in professional activities, and the criterion for its expression is the value attitude to the constructive mastery of information stress; the cognitive-reflective component is expressed through the idea of information stress, strategies for its constructive mastery and reflection on one's own ability to master these strategies, where the criterion is awareness and reflection on the ability to prevent and overcome information stress; emotional-evaluative component contains the experience of satisfaction from the ability to cope with information stress, and the criterion is emotional stability and satisfaction with the level of development of the ability to prevent and overcome information stress; conative-regulatory component provides.
