Authors: Cassandra Lee  , Sufiyati
Published: September 2024

The study aims for empirical evidence about the effect of managerial ownership, institutional ownership, and leverage as independent variables on dependent variable as financial performance with a moderating variable in the form of CSR disclosure in the mining industry listed on the Indonesia Stock Exchange for 2018-2022. Managerial ownership in this study is measured by dividing the number of managers who own shares in the company by number of ordinary shares outstanding. Institutional ownership in this research is measured dividing the number of institutions that own shares in the company by number of ordinary shares outstanding. Leverage in this study is measured by the Debt to Assets Ratio (DAR) which is calculated by dividing total liabilities by total assets. CSR Disclosure in this study is measured by dividing the number of CSR disclosed by total number of CSR. Financial performance in this study is measured by the Return on Assets Ratio (ROA) which is calculated by dividing net income by total assets. The total sample for this research was 10 companies, where the sample was selected using a purposive sampling method. This research data was analyzed using multiple linear regression analysis techniques processed with SPSS 23.0. The results of this research show that institutional ownership has a significant positive influence on financial performance and CSR disclosure is able to moderate the negative influence of institutional ownership and leverage on the company's financial performance, while managerial ownership and leverage do not have a significant influence and CSR disclosure is unable to moderate the influence of managerial ownership on financial performance.
Expansión del capital agrario en el Paraguay. Sus variantes e impactos
Authors: Fogel Pedroso Ramón Bruno
Published: September 2024

En el trabajo se analizan las modalidades e impactos de la expansión del capital agrario en el Paraguay, respondiendo a la movilidad del mercado global de capitales. Esas formas de intervención están asociadas al extractivismo agrario que operan como economías de enclave; éstas al basarse en la explotación desregulada de recursos naturales responden a ciclos de constitución, expansión y decadencia. La caracterización de las formas de extractivismo que se dieron y se siguen desarrollando permite un análisis comparativo de sus impactos. Las conclusiones destacan los costos sociales y ambientales del capital agrario   orientado al extractivismo, con escasos vínculos con el mercado interno, y tiene implicancias para las políticas públicas y para el debate sobre el desarrollo. En el artículo se explotan datos secundarios de tipo estadístico, resultados de investigaciones publicadas y entrevistas semiestructuradas.

Expanding the Boundaries of Feminist Understanding of Art in the Posthumanist Era: Art and Care
Authors: Ermiş Didem
Published: September 2024

In this article, the characteristics that make a work of art feminist in the posthumanist period will be analysed through artworks in which artists show a specific ort his both the materials of their medium and non-human living and non-living things. In addition, a discussion will be carried out about the fact that when the medium and the material become the work itself in a way that reveals different content and expression potentials, it can be characterised as feminist. This discussion will be addressed through the complex relationship between instrumental reason, which can be defined as the determination of the most effective and efficient means to sustain one’s life and for the benefit of one's material interests, and the concept of patriarchy, which expresses the domination of men over women in the axis of education, employment, domestic labour, wages and care. For this reason, firstly, the positions in feminist art debates, then the conditions of attribution of care to women and the struggles initiated against this, and finally the place of artworks that are shaped within the framework of feminism, care and notions of imagination and that are interested in revealing the autonomy of the material in posthumanism discussions will be explained.
Nutritional status of North Koreans and related perceptions among South Korean adults
Authors: Nam Youngmin , Yoon Jihyun
Published: September 2024

Objectives: North Koreans have been facing chronic food shortages and malnutrition. This study examined the nutritional status of North Koreans and the perceptions of South Korean adults regarding their nutritional status. Methods: The nutritional status was examined using nutritional indicators for the general population, children, and reproductive-aged women in North Korea. An online survey was conducted among 1,000 South Korean adults aged 19–69 years to investigate their perceptions regarding the nutritional status of North Koreans.Results: Although the nutritional status of children in North Korea has consistently improved, significant progress in the general population and reproductive-aged women in the country remains elusive. The prevalence of malnutrition among North Korean children has decreased to a level that is not considered severe based on international standards, although it shows a substantial difference from that among South Korean children. The prevalence of undernourishment and food insecurity in North Korea remains over 40%. South Korean adults perceive the nutritional status of North Koreans as being more severe than it is in reality. Notably, a significant inconsistency exists between the perceived and actual nutritional status of North Korean children, with over 95% of South Korean adults perceiving North Korean children’s malnutrition as being more severe than it actually is. Moreover, South Korean adults in their 20s to 40s tended to perceive the nutritional status of North Koreans as being more severe than those in their 50s to 60s did.Conclusions: The nutritional status of North Koreans is a matter of concern. The disparity between South Koreans’ perceptions of the nutritional status of North Koreans and the actual status highlights the need for accurate information dissemination to effectively address malnutrition in North Korea. These efforts could be instrumental in enhancing public awareness and fostering social consensus on food aid and nutritional support programs for North Korea.

Published: September 2024

Urban transportation planning in densely populated areas is a problem in constant need of efficient solutions. Graphs can represent urban street networks and be used to train algorithms, enriching decisions with information learned from structural and topological data of cities. Relational Fusion Networks (RFNs) are Graph Neural Networks specifically tailored for learning on road networks. This work explores the use of RFNs in estimating free-flow travel times and includes experiments on relevant cities from all continents. Results demonstrate the significance of fusion functions and city characteristics in both the learning process of RFNs on regression tasks and the capacity to extrapolate acquired knowledge to different cities.
Análise do impacto da pandemia de COVID-19 na mobilidade no Brasil sob uma visão semântica
Authors: Santos Germano B. dos , Silva Fabrício A. , Silva Thais R. M. Braga
Published: September 2024

Em 2020, o vírus SARS-CoV-2 se espalhou rapidamente no Brasil, implicando no distanciamento social visando a contenção das infecções. A análise da mobilidade, nessa época, foi importante para avaliar a contaminação da população brasileira. No entanto, os efeitos causados no padrão de mobilidade pelas restrições impostas durante a pandemia é ainda pouco discutido. Neste estudo, são analisados 95.522.812 registros de 4.279.025 usuários móveis, referentes aos anos de 2021 e 2022, visando compreender como a população brasileira se adaptou ao novo ambiente pós-pandemia em uma visão semântica da mobilidade humana. A partir da matriz de comparação dos padrões de mobilidade, da avaliação de clusters de usuários móveis baseados na representação vetorial de motifs semânticos e de métricas de deslocamentos, observa-se uma gradual mudança do teletrabalho para o modelo híbrido, aumentando a imprevisibilidade dos deslocamentos dos brasileiros entre 2021 e 2022.

Published: September 2024

A análise de tráfego de dados gerados por dispositivos é fundamental para detecção e mitigação de ataques na Internet das Coisas. Contudo, dados públicos que representem ataques reais ainda são escassos. Visando aumentar a disponibilidade de dados, este trabalho apresenta um estudo do uso de Redes Generativas Adversárias (GANs) para gerar dados sintéticos de ataque em dispositivos IoT com alta fidelidade em relação aos dados reais, isto é, com características similares. Ao mesmo tempo visa garantir privacidade e que a utilidade dos dados sintéticos em tarefas de aprendizado de máquina sejam similares aos reais. Para isso, foram comparamos dois modelos de GANs, CTGAN e NetShare, utilizando como base um conjunto de dados contendo tráfego normal e com ataques em dispositivos IoT. Os resultados indicam que ambos os modelos de GANs são eficientes na geração de dados sintéticos, tanto em fidelidade quanto em qualidade. Entretanto, a CTGAN apresenta-se como o modelo mais eficiente, considerando tempo de execução e consumo de memória.

Authors: R. Júnior Aguimar , Meneguette Rodolfo I.
Published: September 2024

A alocação de recursos em redes veiculares (ARRV) enfrenta desafios crescentes com o aumento do número de veículos conectados, exigindo soluções que lidem efetivamente com a alta mobilidade e a diversidade dos nós. Nesse contexto, a Teoria dos Jogos (TJ) é uma abordagem valiosa, oferecendo um arcabouço matemático para a análise de decisões estratégicas. Este trabalho apresenta o HARMONIC, uma solução heurística que faz uso da TJ para modelar o problema de ARRV. A solução também utiliza o conceito de Shapley Values para otimizar a ordem de alocação de tarefas e distribuir essas tarefas entre um número maior de nuvens veiculares. Os resultados obtidos por meio de simulações mostram uma redução na quantidade de ciclos necessários para alocação e menores taxas de falhas, comparativamente a outras soluções discutidas na literatura.
Federated Learning with Accurate Model Training and Low Communication Cost in Heterogeneous Scenarios
Authors: Souza Lucas Airam C. de , Campista Miguel Elias M. , Costa Luís Henrique M. K.
Published: September 2024

Federated learning (FL) is a distributed approach to train machine learning models without disclosing private data from participating clients to a central server. Nevertheless, FL performance depends on the data distribution, and the training struggles to converge when clients have distinct data distributions, increasing overall training time and the final model prediction error. This work proposes two strategies to reduce the impact of data heterogeneity in FL scenarios. Firstly, we propose a hierarchical client clustering system to mitigate the convergence obstacles of federated learning in non-Independent and Identically Distributed (IID) scenarios. The results show that our system has a better classification performance than FedAVG, increasing its accuracy by approximately 16% on non-IID scenarios. Furthermore, we improve our first proposal by implementing ATHENA-FL, a federated learning system that shares knowledge among different clusters. The proposed system also uses the one-versus-all model to train one binary detector for each class in the cluster. Thus, clients can compose complex models combining multiple detectors. ATHENA-FL mitigates data heterogeneity by maintaining the clustering step before training to mitigate data heterogeneity. Our results show that ATHENA-FL correctly identifies samples, achieving up to 10.9% higher accuracy than traditional training. Finally, ATHENA-FL achieves lower training communication costs than MobileNet architecture, reducing the number of transmitted bytes between 25% and 97% across evaluated scenarios.

Authors: Fontes Ramon dos R. , Lima Thiago de A.
Published: September 2024

O gerenciamento de serviços em uma rede de computadores demanda um esforço considerável para manter a infraestrutura. Tipicamente, os administradores de rede são obrigados a acessar múltiplos servidores, instalar diversos softwares e configurar numerosos arquivos manualmente. Essa abordagem manual frequentemente resulta em erros, afetando a disponibilidade dos serviços. A adoção da infraestrutura como código surge como uma solução para minimizar os equívocos associados ao gerenciamento tradicional de serviços. Neste contexto, apresentamos o DOO, ou DevOpsOrchestrator, uma plataforma integrada que utiliza a infraestrutura como código para automatizar o gerenciamento de serviços.

Published: September 2024

A utilização de aplicações de processamento intensivo em em dispositivos móveis (User Equipment – UEs) carece do auxílio de recursos computacionais externos. Entretanto, aplicações sensíveis à latência exigem recursos próximos aos UEs. No padrão Multi-Access Edge Computing, recursos são espalhados geograficamente na rede das operadoras de telefonia móvel. Contudo, as decisões de alocação de recursos tornam-se complexas com a mobilidade dos UEs, podendo afastá-los dos recursos que os servem. Este trabalho apresenta a plataforma Pythia, uma ferramenta de emulação da mobilidade dos UEs do ponto de vista das aplicações. Seu principal objetivo é suportar o desenvolvimento de estratégias de alocação e de aplicações cientes da mobilidade.
Análise de Séries Temporais Relacionadas a Vulnerabilidades de Software em Dispositivos Expostos à Internet

Published: September 2024

Este artigo explora a relação entre a exposição de dispositivos à Internet e sua suscetibilidade à exploração de vulnerabilidades de software. Destacando a complexidade desse fenômeno, ressaltamos a importância de uma abordagem rigorosa para estabelecer uma relação clara entre exposição e explorabilidade. Propomos então uma visão que considera três elementos interligados: a ocorrência de exploração no mundo real, a exposição de dispositivos vulneráveis e a existência de armas que se aproveitem das vulnerabilidades. Apesar da correlação intuitiva entre exposição e explorabilidade, reconhecemos os desafios em estabelecer uma relação definitiva. Para contornar tais desafios, colhemos dados históricos públicos, de sítios públicos, como Shodan, EPSS e inthewild.io, e apresentamos análises preliminares sobre a relação entre tais séries temporais.

Published: September 2024

A função de análise de dados de redes 5G, definida pela 3GPP, é responsável por analisar os dados de rede e propiciar a execução de ações na rede como resultado da análise. Os sistema de análise de dados de rede 5G da literatura utilizam algoritmos para um único contexto de análise e não permitem a inclusão de novos algoritmos de análise. Como alternativa, este trabalho apresenta um framework para a função de análise dados de redes 5G que permite a inclusão e edição de algoritmos de análise de dados, em uma arquitetura composta por software open-source. Como um estudo de caso, técnicas de inteligência artificial no contexto de detecção de anomalias de redes são incorporadas ao framework.

IPM menjelaskan tentang bagaimana manusia mempunyai kesempatan untuk mengakses hasil dari suatu proses pembangunan, sebagai bagian dari haknya dalam memperoleh pendapatan, kesehatan, pendidikan, dan sebagainya.Di Kota Malang, angka Indeks Pembangunan Manusia (IPM) dikeluarkan oleh Badan Pusat Statistik (BPS). Analisanya dilakukan oleh Bappeda Kota Malang sebagai acuan evaluasi keberhasilan pembangunan, dan penyusunan program lanjutan, agar IPM meningkat, dan pembangunan terdistribusi merata. Hal inilah yang menjadi latar belakang Penyusunan Analisa Indeks Pembangunan Manusia (IPM) Kota Malang Tahun Anggaran 2015. IPM dihitung sebagai rata-rata dari 3 (tiga) indeks yang menggambarkan kemampuan dasar manusia dalam memperluas pilihanpilihan, yaituIndeks Harapan Hidup, Indeks Pendidikan dan Indeks Standart Hidup Layak. Rumus umum yang dipakai adalah sebagai berikut : IPM =1/3 (Indeks Kesehatan + Indeks Pendidikan + Indeks Daya Beli). Hasil analisis kajian ini adalahIndeks Pembangunan Manusia Kota Malang pada tahun 2014 adalah sebesar 79,07. Besaran indeks ini termasuk dalam klasifikasi menengah ke atas. Peningkatan dari tahun 2013 sebesar 0,29 poin. Dengan nilai reduksi shortfall 1,04 termasuk cepat hal ini terjadi di karenakan tingkat besaran IPM Kota Malang sejak tahun 2007 mempunyai cenderung cepat. Ditingkat propinsi angka IPM Kota Malang menduduki urutan ke – 3 (tiga) setelah Kota Surabaya, sehingga mengalami penurunan yang pada tahun 2013 peringkat ke-2 (dua). Secara komposit/parsial di kabupaten/kota di Jawa Timur Indeks Kesehatan pada peringkat 16 (enam belas), Indeks Pendidikan Kota Malang menduduki peringkat ke – 1 (satu) dan Indeks Ekonomi pada peringkat ke-3 (tiga). Apabila dibandingkan dengan kondisi di wilayah Malang Raya untuk IPM Kota Malang masih menduduki posisi pertama, baik di lihat secara angka IPM maupun dilihat dari komposit IPM.

Cybersecurity refers to the actions that are used by people and companies to protect themselves and their information from cyber threats. Different security methods have been proposed for detecting network abnormal behavior, but some effective attacks are still a major concern in the computer community. Many security gaps, like Denial of Service, spam, phishing, and other types of attacks, are reported daily, and the attack numbers are growing. Intrusion detection is a security protection method that is used to detect and report any abnormal traffic automatically that may affect network security, such as internal attacks, external attacks, and maloperations. This paper proposed an anomaly intrusion detection system method based on a new RNA encoding method and ResNet50 Model, where the encoding is done by splitting the training records into different groups. These groups are protocol, service, flag, and digit, and each group is represented by the number of RNA characters that can represent the group's values. The RNA encoding phase converts network traffic records into RNA sequences, allowing for a comprehensive representation of the dataset. The detection model, utilizing the ResNet architecture, effectively tackles training challenges and achieves high detection rates for different attack types. The KDD-Cup99 Dataset is used for both training and testing. The testing dataset includes new attacks that do not appear in the training dataset, which means the system can detect new attacks in the future. The efficiency of the suggested anomaly intrusion detection system is done by calculating the detection rate (DR), false alarm rate (FAR), and accuracy. The achieved DR, FAR, and accuracy are equal to 96.24%, 6.133%, and 95.99%. The experimental results exhibit that the RNA encoding method can improve intrusion detection.
Propuesta de mejoramiento para favorecer la articulación curricular en Lenguaje, entre Educación Parvularia y Básica
Authors: Casanueva Reyes Valeria , Valenzuela Galdames Mabel
Published: September 2024

El objetivo de esta propuesta es asegurar la articulación curricular, en el área del lenguaje, en Educación Inicial y Primer Ciclo Básico, considerando el lenguaje como vehículo fundamental para el desarrollo integral del ser humano. Esto surge a raíz de un diagnóstico realizado, cuyo resultado arrojó la ausencia de lineamientos pedagógicos curriculares respecto a los conocimientos, habilidades y actitudes que se espera que los estudiantes adquieran en cada nivel. Esta propuesta fue desarrollada con base en un estudio de tipo mixto, a través del análisis de resultados académicos en el área del lenguaje, revisión de documentos oficiales de la institución y encuestas a los equipos de aula. Todo esto reflejó la ausencia de una articulación curricular formal entre profesionales de los cuatro niveles que favorezca la transición educativa. Para resolver esta problemática, se elaboró una guía de orientaciones articuladas para trabajar el área del lenguaje, a través de un trabajo colaborativo que, además, contempló la evidencia científica respecto a la importancia de brindar experiencias de aprendizaje significativas durante los primeros años de vida, considerando la relevancia de un aprendizaje basado en el juego.

Objective Cryoballoon ablation for pulmonary vein isolation is a time-efficient procedure that can alleviate stress on electrophysiology lab resources. This analysis modeled the impact of cryoballoon ablation on electrophysiology lab operation using data from Latin America. Methods Data from centers in Argentina, Mexico, Colombia, and Chile of the were used as inputs for an electrophysiology lab efficiency simulation model. The model used the assumption that either two (today’s electrophysiology lab operations) or three (including electrophysiology lab operational changes) cryoballoon ablation procedures could be performed per day. The endpoints were the percentage of days that resulted in 1) overtime and 2) time left for an extra non-ablation electrophysiology procedure. Results Data from a total of 232 procedures from six Latin American centers were included in the analysis. The average electrophysiology lab occupancy time for all procedures in Latin America was 132 ± 62 minutes. In the Current Scenario (two procedures per day), 7.4% of simulated days resulted in overtime, and 81.4% had enough time for an extra electrophysiology procedure. In the Enhanced Productivity Scenario (three procedures per day), 16.4% of days used overtime, while 67.4% allowed time for an extra non-ablation electrophysiology procedure. Conclusions Using real-world, Latin American-specific data, we found that with operational changes, three ablation procedures could feasibly be performed daily, leaving time for an extra electrophysiology procedure on more than half of days. Thus, use of cryoballoon ablation is an effective tool to enhance electrophysiology lab efficiency in resource-constrained regions such as Latin America.
