Small to medium-sized shipyards play a crucial role in the European naval industry. However, the globalization of technology has increased competition, posing significant challenges to shipyards, particularly in domestic markets for short sea, work, and inland vessels. Many shipyard operations still rely on manual, labor-intensive tasks performed by highly skilled operators. In response, the adoption of new tools is essential to enhance efficiency and competitiveness. This paper presents a methodology for developing a human-centric portfolio of advanced technologies tailored for shipyard environments, covering processes such as shipbuilding, retrofitting, outfitting, and maintenance. The proposed technological solutions, which have achieved high technology readiness levels, include 3D modeling and digitalization, robotics, augmented and virtual reality, and occupational exoskeletons. Key findings from real-scale demonstrations are discussed, along with major development and implementation challenges. Finally, best practices and recommendations are provided to support both technology developers seeking fully tested tools and end users aiming for seamless adoption. Full article

VR has shown positive growth in the world in recent years, which is mainly due to projects such as learning, games, entertainment and experiential activities. VR has changed the way of life of users, providing users with more interesting interactions and immersive experiences. This study aims to investigate students’ practical capabilities and learning effectiveness under the instruction strategy of integrating virtual reality into simulation games into the Vehicle Body Electrical System Comprehensive Maintenance and Repair Services Practice curriculum for students of the Dept. of Auto Mechanics in a skills-based senior high school. Two student classes of the Dept. of Auto Mechanics major in Electrical Engineering featuring practical subjects in one skills-based senior high school in central Taiwan were chosen as the participants for this study. By way of pretest–post-test research design and heterogeneous grouping, an 8-week instruction experiment was conducted in which ZPD (zone of proximal development) instruction strategies were used in the experimental group (with 43 persons), while traditional didactic instruction strategies were used in the control group (with 36 persons). ZPD instructional strategies analyze and collect quantitative and qualitative data to investigate the instructional effectiveness and feasibility in developing ZPD as the research material in the practical curriculum for the study area of the Power Machinery in Vehicle Body Electrical System Comprehensive Maintenance and Repair Services practice. According to the research objective, the results are concluded as follows. (1) Students achieved the best learning effectiveness when adopting ZPD (zone of proximal development) strategies in which virtual reality was integrated into the vehicle charging and starting system to investigate students’ automotive diagnostic troubleshooting and fault-clearing capabilities. (2) Students attained the highest acceptance in learning phenomenon when adopting ZPD (zone of proximal development) strategies in which virtual reality was integrated into students’ familiar practice factory environment and the tools and equipment operation process. (3) Students had a higher acceptance of learning effectiveness when using virtual reality simulation games in the disassembly and functional detection of vehicle charging and starting systems. (4) There is a positive effect when integrating virtual reality simulation games into ZPD instruction strategies in the knowledge, skills and attitude on students’ overall inquiry practical capabilities and their learning effectiveness.

As an alternative for university students to continue their professional training during the COVID-19 pandemic, higher education institutions implemented virtual learning modalities. In this context, it was proposed to determine the social representations assumed by university students who are pursuing their studies as future educators. It is presumed that representations related to didactic practices are composed of content (knowledge, skills, and attitudes) and organization (central core and representational system). This is an ethnographic study, with an available nonprobabilistic sample of 227 students from the primary education major at Universidad Técnica del Norte. Verbal association techniques and documentary research were used for information collection. To analyze the data, the IRaMuTeQ software (R interface for texts and questionnaire multidimensional analysis) was used. Two types of analyses were conducted: hierarchical classification and factorial correspondence. In conclusion, a virtuality with difficulties and a careful and responsible face-to-face modality are expressed as meanings associated to the representations, both of which require qualitative changes. Regarding the organization, didactic practice complementarity is assumed to be integrated in a hybrid learning modality. Full article

Realism is indispensable in clinical simulation learning, and the objective of this work is to present to the scientific community the methodology behind a novel numerical and digital tool to objectively measure realism in clinical simulation. Indicators measuring accuracy and naturality constitute ProRealSim v.1.0 (Universidad Europea, Madrid, Spain) which allows the assessing of attained realism for three dimensions: simulated participant, scenography, and simulator. Twelve experts in simulation-based learning (SBL) analyzed the conceptual relevance of 73 initial qualitative indicators that were then reduced to 53 final indicators after a screening study evaluating eight medical clinical simulation scenarios. Inter- and intra-observer concordance, correlation, and internal consistency were calculated, and an exploratory factorial analysis was conducted. Realism units were weighted based on variability and its mathematical contribution to global and dimensional realism. A statistical significance of p < 0.05 was applied and internal consistency was significant in all cases (raw_alpha ≥ 0.9698094). ProRealSim v.1.0 is integrated into a bilingual, free, and open access digital platform, and the intention is to foster a culture of interpretation of realism for its better study and didactic use.

To meet the changing competence requirements for employees in engineering professions, education and training need to adapt accordingly. Learning factories offer various possibilities to design or integrate practice-oriented learning into training measures. Whether this approach in fact facilitates learning and competence development is rarely investigated. For this reason, the objective of this scoping review is to analyze and summarize the existing empirical findings on learning success and competence development in learning factories regarding their evaluation methods and results. Following standardized guidelines (PRISMA, JBI) for scoping reviews, 12 databases were researched. The literature screening led to the identification of 24 publications included in the final analysis. The results indicate that a variety of evaluation methods are used to assess learning and competences at learning factories and that criteria of all four competence facets (professional, methodological, social, and self-competence) can be enhanced at learning factories in general. As many of the identified studies show potential for improvement regarding the quality of the used methods and analysis of results, further studies on these topics are needed. Evaluations should be integrated into all training measures at learning factories to ensure learning success and competence development and to be able to readjust design, structure, and didactics where necessary.

Nowadays, the concept of Industry 4.0 aims to improve factories’ competitiveness. Usually, manufacturing production is guided by standards to segment and distribute its processes and implementations. However, industry 4.0 requires innovative proposals for disruptive technologies that engage the entire production process in factories, not just a partial improvement. One of these disruptive technologies is the Digital Twin (DT). This advanced virtual model runs in real-time and can predict, detect, and classify normal and abnormal operating conditions in factory processes. The Automation Pyramid (AP) is a conceptual element that enables the efficient distribution and connection of different actuators in enterprises, from the shop floor to the decision-making levels. When a DT is deployed into a manufacturing system, generally, the DT focuses on the low-level that is named field level, which includes the physical devices such as controllers, sensors, and so on. Thus, the partial automation based on the DT is accomplished, and the information between all manufacturing stages could be decremented. Hence, to achieve a complete improvement of the manufacturing system, all the automation pyramid levels must be included in the DT concept. An artificial intelligent management system could create an interconnection between them that can manage the information. As a result, this paper proposed a complete DT structure covering all automation pyramid stages using Artificial Intelligence (AI) to model each stage of the AP based on the Digital Twin concept. This work proposes a virtual model for each level of the traditional AP and the interactions among them to flow and control information efficiently. Therefore, the proposed model is a valuable tool in improving all levels of an industrial process. In addition, It is presented a case study where the DT concept for modular workstations underpins the development of technologies within the framework of the Automation Pyramid model is implemented into a didactic manufacturing system.

Sweet maize (Zea mays L. var. saccharata Bailey) is a valuable vegetable adapted to growing in temperate climate conditions. Temperature, especially in the beginning of the growing period, has a crucial effect on vegetation and yield. The best maize initial growth requires soil temperature above 10 °C. Maize covered by polyethylene film and polypropylene non-woven fabric leads to an increase in temperatures which accelerates crop growth. Three years (2012–2014) of field experiments were carried out at the Research and Didactic Station in Psary, belonging to the Department of Horticulture of Wroclaw University of Environmental and Life Sciences. A three-factorial experiment was established using the randomized subblock method in three repetitions in the years 2012–2014. Cobs were harvested in the milk-dough phase of grain maturity. Hybrid Rustler F1 produced, on average, 35.4% more marketable yield than Signet F1. On average, 10.2% more cobs and 22.7% more cobs (with Hybrid Rustler F1 and Signet F1, respectively) were harvested in cases when the sowing was performed in the third decade of April. The use of covers contributed to a significant increase in the yield compared to the yield of uncovered plants. Transparent foil also contributed to a significant increase in the number of cobs harvested in the marketable yield. Full article

Within globalization and the development of information and communication technologies (ICT), social and civic competence and sustainability take on a relevant role in the international scope. To this end, a theoretical section on citizenship models and the different fingerprints of sustainability is presented. The study is quantitative, with a sample of 161 massive open online courses (MOOCs) from three of the main platforms (Coursera, EdX and MiriadaX) with content on citizenship, citizen participation and/or sustainability. Both data collection and analysis are structured around a system of four categories: Technical dimension, didactic dimension, citizenship and sustainability. An exploratory analysis is carried out, followed by a factorial analysis focused on correlations and reduction of factors that allows us to define a main formative profile of the MOOC in relation to the reference themes. In this way, this research concludes that there is an international trend in MOOCs in citizenship and sustainability, whose predominant training proposals include contents related to the ecological citizenship model, as well as issues such as lack of resources, the need to reduce waste derived from consumption, climate change, or the impact of companies on the local economy and environment.
