Τυπολογίες σύνδεσης της σχολικής εγκατάλειψης και της χρήσης παράνομων ουσιών: Αυτοβιογραφίες μελών σε προγράμματα απεξάρτησης
Authors: Κανάρης Παρασχάκης , Χαράλαμπος Πουλόπουλος
Published: September 2024

Η παρούσα μελέτη διερευνά το φαινόμενο της πρόωρης εγκατάλειψης του σχολείου σε άτομα που προσεγγίζουν θεραπευτικά προγράμματα αντιμετώπισης της ουσιοεξάρτησης. Επιχειρεί να αναδείξει τους παράγοντες που ωθούν στη χρήση παράνομων ουσιών και να κατανοήσει τους μηχανισμούς που συνδέουν τη διακοπή του σχολείου και την έναρξη της χρήση ουσιών. Για τους παραπάνω σκοπούς διενεργήθηκε ποιοτική έρευνα με αξιοποίηση εξήντα (60) αυτοβιογραφιών ατόμων που συμμετείχαν σε θεραπεία στο ΚΕΘΕΑ. Σε αυτές αποτυπώνονται σημαντικά βιώματα και εμπειρίες των ατόμων έως τη στιγμή που αυτά απευθύνθηκαν στις θεραπευτικές δομές του οργανισμού. Η επεξεργασία των ερευνητικών δεδομένων έγινε με τη μέθοδο της ανάλυσης περιεχομένου. Τα ευρήματα ανέδειξαν την αλληλεπίδραση των παραγόντων κινδύνου σε διάφορα επίπεδα (ατομικό, οικογενειακό, σχολικό, ομότιμοι) οι οποίοι φαίνεται ότι συμβάλλουν στη σχολική εγκατάλειψη και στην έναρξη της χρήσης παράνομων ουσιών. Σύμφωνα με την ανάλυση περιεχομένου, προκύπτουν τρεις τυπολογίες ως προς τη χρονική στιγμή εμφάνισης των δύο φαινομένων, οι οποίες ερμηνεύουν τις διαφορετικές κατευθύνσεις που μπορεί να πάρουν τα άτομα. Διαπιστώνεται ότι η σχέση ανάμεσα στην πρόωρη εγκατάλειψη του σχολείου και στη χρήση παράνομων ουσιών είναι αμφίδρομη, παρά αιτιολογική, και ότι συναρτάται από την παρουσία ενός συνόλου κοινών παραγόντων κινδύνου, οι οποίοι βρίσκονται σε διαρκή αλληλεπίδραση.
Feminist Paths For Multispecies Ethnography
Authors: Bozok Nihan
Published: September 2024

This article explores the feminist viewpoint that is the basis of the multispecies ethnography that has emerged since the 2000s. Multispecies ethnography is a research and writing method that examines the interconnectedness of different species and acknowledges the significance of non-human beings for establishing culture, community, and nature. It comprehends interactions, entanglements, and associations between humans and more than humans by situating them within all-encompassing ecological frameworks. Feminist discussions about (1) viewing the world from a particular standpoint, (2) the rejection of the distinction between nature and culture, (3) the rejection of human exceptionalism, (4) the recognition of the interconnectedness of lives, and (5) the establishment of a language framework for multispecies form the basis of the methodology. Multispecies ethnography is a method that may demonstrate how nature, plants, animals, and people are all interconnected. It has been enhanced by feminist discussions and has taken on a critical quality. In this way, it can help us see the world as a web of life made up of the ecological connections, interactions, conflicts, and compromises between many species. It may also open the door for creative writing styles and inclusive fieldwork practices.
On “Things” Making Social Possible: Glass, Clock, Contraceptives
Authors: Pehlivanlı Ezgi
Published: September 2024

This theoretical study aims to elaborate on an alternative approach, proposing that social relations are made possible by inanimate objects. For example, the means of production, which are used as a category of analysis in social theory, have been tried to be understood by investigating only their social projections, without mentioning these tools themselves. The main aim of this study is to reconsider this theoretical attitude, which results from sociology's view of lonely people as a category of analysis and which creates a deficiency in making sense of historical and social dynamics. In this context, by combining knowledge archaeology and Actor Network Theory, it is aimed to explain things as tools that make the social possible and to present the thesis that gender-based dynamics and/or social class, can also be investigated with this method.

Authors: Kim Minji , Jang Meera
Published: September 2024

Objectives: This study investigates the relationship between smartphone usage and eating behavior among elementary school students. Methods: This survey was conducted on 4th- to 6th-grade students at elementary schools in Gangneung from September 6th to September 15th, 2023. Of the 129 copies of the questionnaire that were distributed to 5 schools, 66 copies (51.2%) were returned. Results: Compared to the nationwide statistics, the smartphone ownership rate of elementary school students in Gangneung was lower, but the rate of smartphone overdependence was higher. Smartphone dependence was 21.12 points for study subjects and 26.00 points for the overdependence risk group (Org). Compared to national statistics, the self-control failure factor was higher, so study participants in Gangneung City are thought to have great difficulty with self-control. The Org’s weekend smartphone use time of 7.54 hours was significantly more than the general user group (Gug)’s 4.06 hours. The number of days in which the Org consumed late-night snacks per week was 2.92 days, and the Gug had 2.15 days, but the difference was not significant. Eating fast food showed a positive correlation with eating sweet food, eating fatty food, and eating heavily seasoned food. It was found that frequent consumption of fast food is closely correlated with unhealthy eating behavior. Weekend smartphone use time showed a significant positive correlation with smartphone dependence and the number of days late-night snacks consumed per week. Conclusions: Study participants in Gangneung are more dependent on smartphones than national statistics. Smartphone dependence had a negative correlation with healthy eating behavior and a correlation with average unhealthy eating behavior.

This study explores the connections between attributes, consequences, and values. Additionally, it conducts a cross-country comparison of consumers’ online grocery shopping behaviors to gain a deeper understanding of consumer market segments and any potential variations among them. Methods: Data was collected through an online questionnaire survey conducted from May 1 to 15, 2024, targeting 400 consumers in Seoul, Korea, and Shanghai, China, who have experience with online grocery shopping. The survey utilized the Means-End Chain theory and association pattern technique hard laddering. Data collation and analysis were conducted using the IBM SPSS Statistics 28.0 program. The LadderUX software was employed to analyze the links between attributes, consequences, and values and create the consumer purchasing process’s implication matrix and hierarchical value map (HVM). Results: The study identified key attributes that influence online grocery shopping decisions, including delivery service, price, freshness, and quality. Korean consumers demonstrated a higher sensitivity to price (19.0%) and delivery service (17.0%). In contrast, Chinese consumers prioritized delivery service (15.0%) and after-sales service (14.8%). Commonly cited consequences included time saving (12.6% for Koreans, 11.3% for Chinese), whereas prevalent values encompassed convenience (36.8% for Koreans, 19.6% for Chinese) and economic value (26.6% for Koreans, 14.7% for Chinese). The HVM underscored these insights, highlighting diverse consumer preferences and country-specific nuances. Conclusions: The findings highlight the current state of online food consumption and consumers’ value systems, revealing variations among countries. These findings offer empirical insights that can be used to create customized global marketing strategies that resonate with various consumer preferences and market dynamics.

Authors: Lee EunJung , Jang Jin A , Kim Ji-Myung
Published: September 2024

Objectives: This study investigated the association between eating habits and the utilization of dietary supplements (DSs) according to food-related lifestyle (FRL) among Korean adults. Methods: This study included a total of 300 participants (150 men and 150 women) in their 20s to 60s living in Seoul and Gyeonggi Province. We identified two groups by factor and cluster analysis: an ‘active pursuit’ group and a ‘passive pursuit’ group. Differences in eating habits and DS utilization between the two groups were analyzed by chi-square test and t-test. Logistic regression analysis was used to analyze the effect of variables on DS consumption according to FRL. Results: There were significant differences between the two groups in terms of age, alcohol drinking frequency, total dietary score, change in DS consumption after coronavirus disease 2019, and current DS consumption (P < 0.05). The proportion who perceived many health benefits of DSs was higher in the ‘active pursuit’ group than in the ‘passive pursuit’ group (P = 0.003). The most commonly consumed type of DSs was multivitamins & minerals for the ‘active pursuit’ group, and omega-3 fatty acids for the ‘passive pursuit’ group. The ‘an active pursuit’ group consumed DSs 2.93 times more (95% confidence interval [CI]: 1.44–5.97) compared to the ‘passive pursuit’ group, after adjusting for confounders. In the ‘active pursuit’ group, the health pursuit (odds ratio [OR] = 6.54, 95% CI: 1.44– 29.61) and rational consumption pursuit factors (OR = 0.26, 95% CI: 0.08–0.83) were associated with DS consumption, whereas only the health pursuit factor had a significant association (OR = 5.37, 95% CI: 2.08–13.88) within the ‘passive pursuit’ group. However, total dietary score and DSs consumption did not show a relationship. Conclusions: By understanding the consumption characteristics of DSs according to FRL, this can serve as basic data necessary for promoting health through the utilization of DSs and healthy behaviors.

Authors: Svaigen Alisson R. , Ruiz Linnyer B. , Loureiro Antonio A. F.
Published: September 2024

The Internet of Drones (IoD) emerged as a novel mobile network paradigm. IoD is a unique environment with particular characteristics that differ from traditional ones (e.g., drones’ mobility and the fast network topology change), demanding compliance with security and privacy requirements. Likewise, IoD can suffer from novel drone-centered threats. The existent protection mechanisms (PMs) may not be adequate for the IoD environment since they may not embrace the IoD characteristics, also facing new threats. Therefore, the main goal of this dissertation is to study the design of PMs for the IoD, considering its particular characteristics. This study reveals a need to enhance current PMs to meet the IoD characteristics since they can not offer the same protection level. Our contributions advance the state-of-the-art on four fronts: new guidelines for IoD security and privacy field; novel location privacy PMs; novel anti-jamming PMs; and new strategies for automatic drone detection.

Published: September 2024

Dispositivos IoT, incluindo lâmpadas inteligentes, sensores de movimento e sistemas de monitoramento de saúde, já estão presentes em muitos lares e prometem aprimorar nosso cotidiano. No entanto, para indivíduos sem experiência com tecnologia, a conexão desses dispositivos à rede doméstica pode ser um desafio. Muitos desses dispositivos exigem configuração interna ou o uso de dispositivos externos, como um telefone, para a configuração. Este artigo apresenta o OpenAPFinder, um sistema projetado para encontrar e conectar dispositivos ESP8266 em redes domésticas usando exclusivamente o Wi-Fi. O OpenAPFinder permite transmitir o SSID e Senha de uma rede de formar segura para novos clientes ESP8266. Essa abordagem reduz a necessidade de conhecimento técnico ao adicionar novos dispositivos à rede. Os resultados experimentais mostram que o sistema é capaz de integrar novos dispositivos em uma rede Wi-fi. Futuros trabalhos incluem aperfeiçoar a eficiência temporal durante as etapas de reconhecimento, validação do usuário e transmissão de dados.

Ataques de negação de serviço Denial-of-Service (DoS), visam afetar a disponibilidade de aplicações para usuários legítimos. Em ambientes de computação em nuvem, como o Kubernetes, ataques podem ser prejudiciais sem isolamento entre aplicações. Este estudo analisa o isolamento entre contêineres em Kubernetes. Experimentos mostraram que métricas de um contêiner foram afetadas por um ataque em outro na mesma infraestrutura. Os resultados indicam falta de isolamento adequado entre contêineres.

O Federated Learning (FL) é uma técnica distribuída para treinamento de modelos de aprendizado de máquina, em que os dados são processados localmente e apenas parâmetros locais são compartilhados com um servidor de agregação. Apesar dos dados dos clientes serem mantidos localmente, ainda é possível um adversário fazer um ataque de reconstrução de modelo, por exemplo. Sendo assim, este trabalho apresenta o PEGASUS que utiliza das garantias da privacidade diferencial (Differential Privacy (DP)) para mitigar ataques adversários no ambiente de FL. Além disso, o PEGASUS emprega uma estratégia de seleção de clientes que adapta dinamicamente a quantidade de dispositivos que treinam o modelo com o objetivo de lidar com o acréscimo da perda de privacidade (parâmetro ϵ da DP) ao decorrer das rodadas de comunicação. Avaliações experimentais mostram que PEGASUS reduz significativamente a perda de privacidade (58%) dos clientes participantes do treinamento e mantém bons níveis de acurácia (97%).

Artificial Intelligence (AI) is essential for evolving mobile networks towards 6G technology generation and beyond. In this context, the 3GPP has incorporated the Network Data Analytics Function (NWDAF) at the network’s core to leverage network data analytics, focusing on using analytics for automation. However, although NWDAF represents a significant advancement in this area, there is no consensus on deploying AI in the 6G network. This work suggests a framework for developing NWDAF that includes the necessary interfaces and behaviors to enhance the core network with AI capabilities Beyond 5G (B5G) and 6G networks. By analyzing existing literature, we identify a set of potential research directions and propose and suggest a hybrid approach to integrate AI across the entire network using a new distributed network function called Evolved Network Data Analytics Function (eNWDAF).

Published: September 2024

Modern network architectures have shaped market segments, governments, and communities with intelligent and pervasive applications. Ongoing digital transformation through technologies such as softwarization, network slicing, and AI drives this evolution, along with research into Beyond 5G (B5G) and 6G architectures. Network slices require seamless management, observability, and intelligent-native resource allocation, considering user satisfaction, cost efficiency, security, and energy. Slicing orchestration architectures have been extensively studied to accommodate these requirements, particularly in resource allocation for network slices. This study explored the observability of resource allocation regarding network slice performance in two nationwide testbeds. We examined their allocation effects on slicing connectivity latency using a partial factorial experimental method with Central Processing Unit (CPU) and memory combinations. The results reveal different resource impacts across the testbeds, indicating a non-uniform influence on the CPU and memory within the same network slice.

A tarefa de integração com APIs pode ser onerosa, tanto em tempo como por conta de custo com pessoal. No caso de Redes Definidas por Software (SDN), que utilizam o controlador ONOS, essa situação é especialmente problemática já que ele não possui um SDK. Este trabalho apresenta uma solução para gerenciamento de dispositivos, denominada OCClient. Inicialmente a solução foi desenvolvida para ser uma ferramenta de apoio ao grupo de trabalho da UFPA, durante a fase 1, do programa OpenRAN@Brasil. Posteriormente, notou-se um interesse da comunidade por uma ferramenta que pudesse auxiliar na interação com o controlador. Por tratar-se de um binário, pode ser executado na maioria dos ambientes, sem a necessidade de instalação, facilitando a adoção em fluxos automatizados de gerenciamento de configuração de redes, tal como acontece na abordagem GitOps. Para os testes foi provisionado um laboratório com dispositivos emulados pelo CNETLAB e um controlador, um arquivo JSON, contendo as declarações dos dispositivos e respectivos links foi utilizado para aplicar as configurações de registro dos dispositivos no controlador. Posteriormente, a ferramenta também foi utilizada para realizar a remoção dos dispositivos do controlador. E por fim, foi realizada uma comparação entre aplicar as configurações através da ferramenta ou por meio de uma implementação direta utilizando utilizando uma linguagem de programação.

Published: September 2024

A distribuição natural dos dados e questões de privacidade e segurança justificam a necessidade de sistemas eficientes para lidar com dados distribuídos. Por outro lado, a escassez de dados é um desafio para o aprendizado de máquina, o que pode ser mitigado com uma abordagem distribuída. Este trabalho utiliza uma topologia virtual hierárquica baseada em hipercubos para organizar a troca e agrupamento de resultados de treinamento distribuídos, aumentando a acurácia dos modelos finais e oferecendo uma solução tolerante a falhas. Resultados experimentais confirmam a eficácia da técnica, com melhoria dos resultados em todos os cenários simulados.

Published: September 2024

Os ataques de negação de serviço - Denial-of-Service (DoS) estão mais frequentes e sofisticados, tornando-se um grande desafio da atualidade, impactando negativamente as empresas, causando prejuízo financeiro e danos à reputação. Além disso, esses ataques são gerados visando assemelhar-se a clientes legítimos, dificultando a ação das ferramentas de detecção/mitigação. Portanto, este artigo propõe o uso da funcionalidade de dimensionamento automático, disponível na plataforma Kubernetes, para oferecer uma maior disponibilidade durante um ataque DoS. Verificou-se, durante a realização de experimentos, que os clientes tiveram um aumento da disponibilidade e uma diminuição do tempo de serviço quando a estratégia de dimensionamento automático estava ativada, durante os ataques.
