Prospective informatics teachers in vocational schools (VS) must master content knowledge, pedagogical skills, and technology integration to achieve learning goals. Therefore, informatics teachers in VS need to innovate to increase students' creativity. However, many prospective informatics teachers experience difficulties in this regard. This research aims to develop and implement the Web-Based Microteaching (WBM) model to improve the teaching skills of prospective informatics teachers at VS. This study uses research and development methods with the ADDIE model approach. The research results show that the WBM model effectively improves prospective informatics teachers' teaching skills, especially in planning lessons and practising basic teaching skills. This innovation is a relevant learning solution in the digital era and positively contributes to the professional development of informatics teachers. The WBM model is an innovation to provide a more intensive and structured practical experience by utilizing web technology as the main media. Through web-based learning, prospective teachers can access material, exercises and feedback independently, which is expected to accelerate pedagogical mastery. © 2025 The Authors

Medical Gas is an important component in the treatment of patients with COVID-19 disease. Medical gas is used to help COVID-19 patients to reduce the effects of respiratory disorders by providing oxygen ventilators to patients. With the surge in typical COVID-19 sufferers as of July 2021, the need for Oxygen in hospitals is getting higher. This is when the control and monitoring of medical gases in hospitals are late because the integrated system is very dangerous. Therefore, a system that can be used to control and monitor medical gases in hospitals that are integrated and automated and can be monitored by the Government and Medical Gas Producers. This is useful for anticipating the lack of availability of Medical Gas in hospitals. In this study, the system used IoT systems as a base in delivery and control. This system uses Arduino as a minimum system that reads the press sensor on the Medical Gas tube and regulates the valve. The data obtained is then sent to the Local Server to be processed and delivered to the Hospital Officer. Local Servers also send the data to cloud servers to be monitored by the government funds of several medical gas producers. This design can help in the process of controlling and monitoring Medical Gases in hospitals in hopes of minimizing the risk of delays in supplying medical gases to hospitals. © 2021 Institute of Physics Publishing.

A growing number of virtual courses are being offered by Brazilian educational institutions, requiring the development of technological resources and research to assist in Distance Education (DE) teaching and learning processes. Analysis of students’ socio-affective profiles in Virtual Learning Environments (VLE) enables possibilities to develop methodologies and resources to better understand them. The Social Map (SM) and Affective Map (AM), both features of the Cooperative Learning Network (in Portuguese: ROODA), provide inferences and graphic presentations of students’ socio-affective profiles. This article aims to identify the possible recurrent socio-affective scenarios in a VLE utilizing Learning Analytics (LA). LA is defined as the measurement, collection, and analysis of data. The qualitative and quantitative research approach used in this work was carried out based on 10 case studies. The target audience was 219 students including undergraduate, graduate, teachers, and elderly people who participated in teaching activities at a university. Data collected from the SM and AM were extracted in order to identify the relationship between these two aspects. As a result, 38 socio-affective scenarios were created using LA to contribute to the analysis of the students’ learning profiles, allowing teachers to develop pedagogical strategies consistent with the needs of each individual. © 2022, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.

The educational data can be mined to produce the useful knowledge. This paper focuses on the educational data processing to predict student's psychomotor domain. Here, we apply linear regression method to do it. On process stage, we use 4 regularizations, namely: no regularization, ridge regression, lasso regression and elastic net regression. Furthermore, we exploit 2 sampling methods as the evaluation technique, for examples: cross-validation sampling and random sampling. The experimental result indicates that the best regularization on cross-validation and random sampling are an elastic net regression because this regularization achieves the lowest predicting error. On cross-validation, values of MSE, RMSE, and MAE are 40.079, 6.330 and 5.183, respectively. Additionally, for random sampling, respectively, values of MSE, RMSE, and MAE are 86.910, 8.428 and 6.511. © 2018 IEEE.

The utilization of data warehouses in various fields is an absolute necessity. A data warehouse is a database that contains large amounts of data that aims to help organizations, fields, and institutions specifically for decision making. Data warehouses can produce important information in the future. Loading data from various sources and processed through an ETL (Extract, Transform, Load) process that displays data consistently is the basis for creating a data warehouse architecture. The development of a data warehouse in education will provide significant benefits for the progress of education. Integration of data and processing results stored in the data warehouse can be the basis for evaluating better planning. Development of data warehouse adopt the multidimensional modelling method which consists of four stages: select the business process, declare the grain, select dimensions, and identify facts. This stage produces a data warehouse architecture and influences and contributes to the advanced information technology in education. © 2021 Institute of Physics Publishing. All rights reserved.

Resulting from an interdisciplinary endeavor, the paper proposes an ontological model for supporting collaborative work practices in critical settings, and shows its application to a specific domain. The model is empirically-grounded, as based on ethnographic research carried out at an international airport-clearly an example of safety-critical environment, where emergency prevention and preparedness are crucial. On the other hand, the model leverages on previous ontological work on collaboration and observation in emergency response, and revises it when necessary, thus contributing to its development. Taking hand-baggage screening as an example, the paper shows how the model can be applied, and how it could be used to run model-based simulation in order to better understand collaborative work practices and analyze the impact of different techno-organizational changes on such practices and their effectiveness. This could result in suggesting guidelines for enhancing workflow, security policies and, more generally, time- and safety-critical situations management.

This paper describes a comparison of two FPGA Montgomery modular multiplication architectures: a fully systolic array and a parallel implementation. The modular multiplication is employed in modular exponentiation processes, which is the most important operation of some public-key cryptographic algorithms and the most popular of them is the RSA encryption scheme. The proposed fully systolic array architecture presents a high-radix implementation with carry propagation between the Processing Elements. The parallel implementation is composed by multipliers blocks in parallel with the Processing Elements and it provides a pipelined operation mode. We compared the time × area efficiency for both architectures as well as a RSA application. The fully systolic array implementation can run the 1024 bit RSA decryption process in just 3.23 ms and the parallel architecture executes the same operation in 6 ms, which means a competitive state-of-art performance for both architectures. © 2010 IEEE.
