Identity Matters: A Framework for Bridging Contemporary e-Learning Theory with Online Practice
Authors: Charbonneau-Gowdy Paula , Galdames Caro
Published: June 2024

We are increasingly realizing that technology and its use in learning contexts is not benign. With the advent of more powerful technology tools, including Artificial Intelligence (AI) ones, combined with the historically significant changes that have occurred in education over the last four years, there are more reasons than ever to examine their influence on human beings in the process of “being educated”. The aim of our 3-year longitudinal study was to understand how programs being offered at a fully online technical higher education (HE) institution in Chile influenced the identity development of students from socio-economically and educationally disadvantaged backgrounds. A Participant Action Research (PAR) approach was adopted to the study that involved macro, meso and micro-driven changes being made to programs. These changes involved aligning the instructional design, pedagogical approaches, and technology tools of programs with contemporary e-learning theory and 21st century learning goals. Previously, we provided three in-depth reports of the evolving changes on learners’ identities - in the beginning, mid and end phases of their programs. We also reported on teachers’ perspectives of learners’ evolving identities and the transformation of their own roles and practices during the change period. In this paper, we add to those findings with the results of a recent inquiry into the perspectives of macro-level administrators who were instrumental in the collaborative effort to bring about change to the institution. In this latest study, we employed in-depth focus group and individual interviews to unpack what the change involved on the part of these decision makers in terms of their own epistemological and ontological perspectives, their roles in the institution and their future goals for the organization. The framework we have developed for schematizing the results of these previous inquiries and those of the overall longitudinal study could prove useful in other organizations that are awakening to the need to successfully put e-learning theory to practice in their institutions. The insight to be gained in this framework could add to their efforts to seek pragmatic ways to bring about systemic changes in their online programs and to graduate students with the kinds of identities and skills that will best equip them for the complex world in which they will work and live.
Bolsonaro's Equation for Social Assistance Policy during his Degovernment: Less Resources, More Expressions of the Social Issue in Brazil
Authors: Lima Sobrinho Jodeylson Islony De , Veiga Gabriel da
Published: June 2024

The National Social Assistance Policy in Brazil during the Bolsonaro (dis)government period is vehemently affected by its ultraneoliberal dynamics of underfunding and moralization. Therefore, the present work seeks to present some aspects about the defunding, implementation and effectiveness of this policy in this period. Our methodology encompasses bibliographical and documentary research of the exploratory type, using historical-dialectical materialism as a method. Therefore, we conclude that Bolsonaro fulfilled the objective he proposed when he became president of the republic of dismantling any type of social protection for the most vulnerable, like the National Social Assistance Policy itself, aggravating social inequalities.

Published: June 2024

The larval stages in vannamei shrimp can be referred to as vulnerable stages that are prone to experiencing environmental crises, mainly due to the inadequate availability of food. Chaetoceros sp. is commonly used as a natural food source because it contains high nutrition that fulfills the larva's requirements for survival. However, the lack of proficiency in proper culture techniques impacts the success of cultivating Chaetoceros sp. as natural food. The objective of this study is to understand the culture techniques and challenges in cultivating natural food and to assess the effects of feeding Chaetoceros sp. on vannamei larvae (Litopenaeus vannamei). The data obtained in this study were analyzed descriptively, meticulously presenting the findings in a clear manner. In laboratory-scale Erlenmeyer culture, the peak plankton growth reached 15.3 million cells/mL, whereas in the Carboy, the density reached up to 5.1 million cells/ml. On the intermediate scale, plankton growth started at 550,000 cells/ml on the first day and increased to 1.8 million cells/mL on the eighth day. The effect of feeding Chaetoceros sp. as natural food source for vannamei larvae resulted in meeting the nutritional needs for the shrimp's body, contributing to the larval development with a relatively high survival rate of approximately 85%.

Published: June 2024

Reducing morbidity in the vaccinated childhood population can reduce the socioeconomic burden on the health system, increase access to health care, which in low- and middle-income countries can also help reduce poverty and inequality. Today, vaccinations are considered as profitable investments in the health care system and the comprehensive development of the state, and the consistently high coverage of the population with immunoprophylaxis is an important task of public health systems. The purpose of the work was to carry out medical and social substantiation and develop a model for optimizing vaccine prophylaxis among children at the primary level of providing medical care. The research was carried out by the method of interviewing respondents, the first group consisted of 280 children who were completely unvaccinated and the second group of 180 children who received a full course of vaccination or were partially vaccinated. Data were copied from the form of the primary accounting documentation No.112/o "History of the child's development". In the development and medical and social substantiation of the model for the optimization of vaccine prophylaxis among children, data obtained during the conduct of own research were used. During the implementation of this work, the determinants that affect the level of vaccination among children and the attitude of the population to the organization of vaccine prevention were determined. Urgent issues for Ukraine are the revision of legislative norms in the field of immunization and prevention to ensure the full coverage of the population with vaccinations and strengthening the responsibility of citizens for refusal and untimely receipt of vaccines.

Published: June 2024

We aimed to improve the detection sensitivity for liquid measurement by developing an ultrathin photoelectron transmission window (SiNx membrane) for liquid cells via X-ray photoelectron spectroscopy or X-ray photoelectron emission microscopy at an ultrahigh vacuum. The membrane using gas-cluster ion beams (GCIB) was thinned, and its burst pressure was compared with those of membranes thinned with atomic 400 eV Ar+ ions. The SiNx membranes thinned by GCIB had approximately 2.5 times higher burst pressure than Ar+ ions. In addition, the improved sensitivity of the characteristic X-ray from liquid water induced by low-energy electrons was investigated. With the use of the 4.5 nm-thick SiNx membrane etched by GCIB, the X-ray intensity became 1.6 times higher than those of the 11 nm-thick pristine membrane at the electron beam (EB) energy of 1.5 keV. This result showed a good agreement with Monte Carlo simulation results of the EB-induced X-ray emission from liquid water beneath the SiNx membrane.

Methylammonium lead iodide (CH3NH3PbI3; MAPbI3) films were fabricated from sputtered lead sulfide (PbS) films prepared at various substrate temperatures according to the Thornton structural zone model. PbS films were converted to lead iodide (PbI2) and finally to MAPbI3 in a two-step gas-phase reaction. The increase in substrate temperature caused the morphology to change to fibrous interconnected grains, which played an important role in improving the optoelectrical properties of perovskite films. Moreover, enhanced charge transport of MAPbI3 films was observed owing to the fibrous interconnected PbI2 precursor, which was confirmed by a higher absorption coefficient and longer carrier lifetime.

Joint Supervised and Unsupervised Machine Learning for Spectrum Sensing
Authors: Manzoor Bisma , Al-Hourani Akram
Published: June 2024

As the Internet of Things (IoT) applications continue to experience
exponential growth, the resulting congestion in frequency spectrum
highlights the necessity for innovative spectrum monitoring techniques.
Spectrum sensing plays a crucial role in cognitive radio systems by
facilitating the efficient utilization of spectrum through the detection
and utilization of unused frequency bands. This work presents a novel
methodology for detecting radio frames from a noisy spectrum. We
implement joint machine learning comprising a supervised Semantic
Segmentation neural network and unsupervised Density-Based Spatial
Clustering of Applications with Noise (DBSCAN) to detect IoT packets
from the spectrogram images. The proposed method achieves 95.4% mean
accuracy and 93% mean intersection-overunion (IoU) at low
Signal-to-Noise Ratio (SNR) level. Moreover, the proposed method
outperforms the traditional threshold detection methodologies as
demonstrated by the Receiver Operating Characteristics (ROC).
A Framework for Integrating Artificial General Intelligence into Engineering Education: Enhancing Human-Centric Approaches for Industry 5.0
Authors: Balart Trini S , Shryock Kristi J.
Published: June 2024

In this paper, we present an advanced conceptual framework for
integrating Artificial General Intelligence (AGI) into engineering
education (Artificial General Intelligence Integration into Engineering
Education (AGIE)). Our aim is to
harmonize technical skills with intrinsic human qualities, such as
creativity and ethical reasoning, essential for the Industry 5.0
landscape. This framework is based on comprehensive literature reviews
and empirical data from student and faculty surveys, analyzed to assess
AGI’s potential to foster these human-centered qualities. Our proposal
includes dynamic, interdisciplinary learning environments, personalized
educational trajectories, continuous adaptation, and lifelong learning,
addressing the ethical issues of AGI application. This framework not
only advances engineering education to meet Industry 5.0 demands but
also fosters holistic, human-centered learning experiences, preparing
technically competent engineers equipped with vital interpersonal
skills. This work builds upon previous research presented at a
conference on integrating AI into engineering education.
On the Impact of Flooding Attacks on 5G Slicing with Different VNF Sharing Configurations
Authors: AbdulGhaffar AbdulAziz , Mahyoub Mohammed , Matrawy Ashraf
Published: June 2024

Virtualized Network Function (VNF) sharing among multiple Fifth
Generation (5G) slices allows network operators to increase the
efficiency and utilization of the network. However, this sharing of VNFs
can result in a degradation of the performance of the slices in the
presence of an attack. In this paper, we evaluate the impact of flooding
attacks on the performance of 5G slices with different VNF sharing
configurations. We consider two VNF sharing configurations, in the first
configuration, the Session Management Function (SMF) and User Plane
Function (UPF) are shared among the deployed slices, while the SMF and
UPF of the slices are isolated in the second configuration. The
performance of these configurations is evaluated using different traffic
types under two flooding attack scenarios; a ping flood attack targeting
the data plane of 5G network, and a registration request flood attack
directed at the control plane of 5G network. Our results showed
different responses in the control and data planes. In the data plane,
isolating VNFs of the slices provides better performance and mitigates
the adverse effects of the attacks studied.

Izin kerja merupakan suatu dokumen tertulis yang digunakan sebagai syarat dalam bekerja melaksanakan pekerjaan berbahaya dengan memperhatikan potensi bahaya yang ada dan tindakan yang diantisipasi, serta cara mengendalikannya. Pekerjaan yang mempunyai potensi bahaya sedang bekerja di ketinggian. Di dalam permohonan izin kerja, masih banyak yang kurang maksimal dan belum masuk sesuai SOP (Standard Operating Procedure), dalam persetujuan pekerjaan izin. Berdasarkan pemasalahan diatas dilakukan review artikel dengan mengumpulkan literatur jurnal melalui google scholar untuk menganalisis implementasi izin kerja panas. Sistem izin kerja yang aman sangat penting dalam pekerjaan seperti pemeliharaan pabrik kimia di mana potensi risikonya tinggi dan memerlukan koordinasi kegiatan serta tindakan pencegahan yang cermat untuk keselamatan kerja. Dalam situasi ini dan situasi yang memiliki potensi risiko yang serupa, prosedur perizinan dalam bekerja sangat diperlukan. Peran dari prosedur perizinan adalah untuk untuk memastikan bahwa pekerjaan yang berpotensi sangat berbahaya (misal pekerjaan diruang terbatas) dilakukan dengan aman. Prosedur perizinan yang dimaksud adalah izin kerja yang juga merupakan salah satu safe operating prosedure dalam unit proses.
