Continuing Educational Program in Nursing Informatics for Greek Nurses.

Nurses are required to adapt to a complex and rapidly evolving environment that incorporates new IT technologies. Continuing, lifelong learning, especially in the fast-growing fields of Nursing Informatics, eHealth and related Information and Communication Technologies, is vital to the professionalism of nurses. The study presents the curriculum development and implementation of the educational project entitled "Training of Nurses in Nursing Informatics and Information and Communication Technologies (ICT)" which has been designed and offered to Greek nurses as a continuing - lifelong online educational program by the Health Informatics Laboratory of the National and Kapodistrian University of Athens. The training material was created in three modules and 29 sub-modules, considering the new advancements and recommended competencies, necessary for the nurse, in the fields of Nursing Informatics and ICT. So far, eight training cycle courses have been offered to 1388 nurses, free of charge. Each course integrates synchronous and asynchronous distance learning methods and requires a workload of 70 hours over 10 weeks. The initial evaluation of the course by the participants, concerning its effectiveness, usefulness, and innovation are very encouraging.

A Framework to Identify Non-Achievers in eLearning Business Informatics Lab Courses

Learning Management Systems store valuable data in their repositories. Analyzing such data could contribute to identifying non-achievers in eLearning courses. This study presents an integrated framework (encompassing stages from a risk management process) to predict non-achievers in eLearning Business Informatics Lab Courses through a discriminant function analysis of student engagement data. In detail, data regarding with student interaction with the learning activities were elicited from the Moodle LMS log files. The paper also presents a specific eLearning Business Informatics Lab Course, designed upon Business Informatics competencies, tailored to a Business Informatics Curriculum for undergraduate Accounting Students. A discriminant function analysis was used to develop a competent prediction model. Linear discriminant functions were generated for achievers and non-achievers respectively. Students were classified into non-achievers or achievers according to the maximum score of the discriminant functions. The high classification percentage of our model indicates that our framework could be used to identify non-achievers in any eLearning Business Informatics Lab course sharing the same structure. A linear discriminant analysis (LDA) was also employed to indicate the training potential of our model. The evaluation metrics of our trained model indicate that our model could potentially be used to develop an alert system.

Biomedical Engineering Research Based on Computer Propagation Technology: Treatment of neurodigestive diseases

With the support of the Institute of Cancer Hospital of Chifeng University, Sarkov and Markov Memorial Health Informatics Laboratory designed a new working concept of innovative Nursing by using neural network and Brain–computer interface technology. The research team proposed a direct connection between human or animal brain (or brain cell culture) and external equipment. In the case of one-way Brain–computer interface, the computer may accept commands from the brain. Using this point to detect the emotion of patients after surgery and carry out necessary gourds, a two-way information exchange method and model of two-way Brain–computer interface are also proposed. The potential non-invasive Brain–computer interface designed by us has been deeply studied, mainly because of its good time resolution, ease of use, portability and relatively low price. Especially in the specific application and working practice of EEG (Electroencephalography), our achievements directly meet the application of clinical institutions.

LAMIS-DMDB: A new full field digital mammography database for breast cancer AI-CAD researches

The current state of machine learning (ML) and deep learning (DL) shows that they are powerful tools that can be used to glean knowledge from a huge amount of data. While a great deal of research in this area has centered around improving the accuracy and efficiency of training and inference algorithms, there has been relatively little attention paid to the equally important problem of monitoring the quality of data. To tackle this challenge, we have created a cutting-edge breast database capable of employing ML and DL algorithms to detect and classify breast cancer. It is noteworthy that compared to other digital mammogram databases (DMDB), the Laboratory of Mathematics, Informatics and System (LAMIS) images have better resolution and are in full-field digital mammography (FFDM) format. Furthermore, the images can be accessed according to their abnormality (normal, benign, malignant), lesions classification (mass, calcification, architectural distortion, multiple finding), American College of Radiology (ACR) density classification (ACR1, ACR2, ACR3, ACR4) and Breast Imaging Reporting and Data System (BI-RADS). Specifically, the database is designed to provide a variety of metadata as well as clinical data in simple comma separated values (CSV) format that can be really beneficial to the breast cancer research community and to the development of computer-aided diagnosis (CADx) tools that rely on artificial intelligence (AI) algorithms, such as those based on DL models.

Development of 21st-Century Skills and Competencies in High School Students Through the Interactive E-Books Creation

Currently, the need to prepare students for the challenges of the 21st-Century is being recognized, referred to as Education 4.0. This paradigm aims to redefine the education model by fostering the development of 21st-Century skills and competencies, such as problem-solving, creativity, collaboration, communication, and learning to learn. Therefore, this article explores the uses of the Teacher Assistance Educational Process (TAEP4.0) in a real educational scenario. TAEP4.0 is a student-centered process inspired by Education 4.0, which assists teachers in creating projects in the Informatics Lab. The TAEP4.0 process was implemented through a case study focused on fostering 21st-Century skills and competencies among High School students, using the Book Creator platform for interactive e-book creation projects. TAEP4.0 consists of a series of steps that include suggested activities, tools, and support materials. However, teachers have the flexibility to adapt the TAEP4.0 process, exercising their creativity and making decisions regarding project elements, such as the choice of Information and Communication Technology (ICTs) for project creation and monitoring, with the aim of promoting skills and competencies. In this case study, five classes of two High School teachers participated, involving a total of 189 students in the projects. The data collected were analyzed both quantitatively and qualitatively. During the projects, students engaged in activities and reported difficulties, primarily related to communication and teamwork. This feedback enables teachers to gain insight into students' challenges in applying the necessary skills to produce a project. Such evidence can assist teachers in addressing these issues in the future, allowing for project reuse and the creation of new projects that focus on improving specific skills and competencies.

Adopting a metaverse-based workspace to support research team collaboration: a pilot study from an academic health informatics laboratory.

This study aimed to understand how a metaverse-based (virtual) workspace can be used to support the communication and collaboration in an academic health informatics lab. A survey of lab members (n = 14) was analyzed according to a concurrent triangulation mixed methods design. The qualitative survey data were organized according to the Capability, Opportunity, Motivation, Behavior (COM-B) model and combined to generate personas that represent the overall types of lab members. Additionally, scheduled work hours were analyzed quantitatively to complement the findings of the survey feedback. Four personas, representative of different types of virtual workers, were developed using the survey responses. These personas reflected the wide variety of opinions about virtual work among the participants and helped to categorize the most common feedback. The Work Hours Schedule Sheet analysis showed the low number of possible collaboration opportunities that were utilized compared to the number available. We found that informal communication and co-location were not supported by the virtual workplace as we had originally planned. To solve this issue, we offer 3 design recommendations for those looking to implement their own virtual informatics lab. First, labs should establish common goals and norms for virtual workplace interactions. Second, labs should carefully plan the virtual space layout to maximize communication opportunities. Finally, labs should work with their platform of choice to address technical limitations for their lab members to improve user experience. Future work includes a formal, theory-guided experiment with consideration on ethical and behavioral impact.

An Intelligent Data-Driven Approach for Electrical Energy Load Management Using Machine Learning Algorithms

Data-driven electrical energy efficiency management is the emerging trend in electrical energy forecasting and management. This fusion of data science, artificial intelligence, and electrical energy management has turned out to be the most precise and robust energy management solution. The Smart Energy Informatics Lab (SEIL) of the Indian Institute of Technology (IIT) conducted an experimental study in 2019 to collect massive data on university campus energy consumption. The comprehensive comparative study preparatory to the recommendation of the best candidate out of 24 machine learning algorithms on the SEIL dataset is presented in this work. In this research work, an exhaustive parametric and empirical comparative study is conducted on the SEIL dataset for the recommendation of the optimal machine learning algorithm. The simulation results established the findings that Bagged Trees, Fine Trees, and Medium Trees are, respectively, the best-, second-best-, and third-best-performing algorithms in terms of efficacy. On the contrary, a reverse ranking is observed in terms of efficiency. This is grounded in the fact that Bagged Trees is most effective algorithm for the said application and Medium Trees is the most efficient one. Likewise, Fine Trees has the optimum tradeoff between efficacy and efficiency.

Temperature simulation and control for lab-scale convection dehydrators

Abstract We are in the age of Smart Industry or Industry 4.0. Its application is very important in situations that can be simulated and allow process control in university teaching lab practices. Therefore, this research is focused on the “Temperature simulation and control for lab-scale convection dehydrators” that can be used to dehydrate fruits and vegetables as a practical application. The research was carried out by the Informatics laboratory of the Agroindustrial Engineering professional school of the Universidad Nacional de Moquegua, using National Instruments’ LabView software version 2016 to simulate and control the temperature within a lab-scale convection dehydrator. The programming block diagram was developed along with the front panel of the temperature and control simulation for a lab-scale fruit and vegetable dehydration chamber in which the heat generator could be turned on and off when the temperature was below or above the set point, while keeping the dehydrator in operation. The results expected were successfully achieved for the programming of the dehydration chamber’s temperature simulation and control, as the heat generator operates at the temperature set point by turning the system on and off.

Prepared for work in Industry 4.0? Modelling the target activity system and five dimensions of worker readiness

ABSTRACT Within Industry 4.0 research, the spotlight shines on technological and organisational challenges. This study shifts the focus to worker readiness, beginning with an analysis of twenty-three models to establish the state of research. Findings demonstrate that existing models are mostly early-stage proposals addressing competences featured in mainstream 21st-century and digital-competence frameworks. Worker-level factors explicitly aligned with emerging cyber-physical systems receive little attention. To construct a worker-readiness model calibrated to the needs of Industry 4.0, the authors devised a research procedure based on a two-phase integrative review of 135 publications. Firstly, they deployed an activity-system apparatus to produce a structured description of the target environment. Secondly, major worker competence groupings, aligned with this target, were extracted, tagged and reduced to five dimensions. The resulting model consolidates prior research and introduces two original competence groupings addressing human-machine partnering and decision-making in Industry 4.0. This study is a foundational step by the Educational Informatics Lab, Ontario Tech University, Canada, toward deploying a global online profile tool for generating, analysing and aggregating worker readiness profiles. This cross-disciplinary project will help researchers, educators, corporate trainers, human resource managers, policymakers, and systems designers more effectively diagnose the readiness of workers for Industry 4.0.

Temperature simulation and control in refrigerated storage chambers for fruit

Fruits such as guava or grapes need to be stored for long times under refrigerated conditions, in order to prevent decay. Therefore, it is important to count on a refrigerated storage chamber with controlled temperatures, as required by every stored fruit. The temperature in the refrigeration system’s steam-compression evaporator will be limited by the temperature required by the cold storage chamber. The purpose of this research was to develop a program for temperature simulation and control for refrigerated storage chambers for fruit. The programming research was carried out at the Informatics Laboratory of the Agroindustrial Engineering school of the Universidad Nacional de Moquegua, Peru. The temperature simulation and control program for refrigerated storage chambers for fruit was developed with National Instruments’ LabVIEW programming language, 2016 version. The simulation and modeling programming block diagram and front panel were developed for temperature control in such storage chamber, which will allow the evaporator’s operation when the temperature sensor shows temperatures above the set point and deactivation when the temperature is below the set point, in order to keep the temperature required for conservation of the fruits stored.
