Augmented reality is gaining more and more interest in fields such as education, medicine, tourism, marketing, and manufacturing. However, the creation of this type of applications has been dominated by software development methodologies, and only recently have co-design and co-creation approaches been integrated to favor a more effective development to meet specific needs. This paper reports the results of a systematic literature review of 40 scientific articles on the co-design and co-creation of augmented reality experiences, with the aim of providing a landscape of the current state of research in this field. The results show that most augmented reality experiences have been co-designed or co-created for the fields of education and engineering. Moreover, most of the current research has followed an exploratory and cross-sectional approach with small and medium research samples, using classical methods for data collection. Overall, there is an increasing interest in the use of co-design and co-creation methodologies for developing augmented reality experiences. This paper also presents some trends and future lines of work. [ABSTRACT FROM AUTHOR]

This article proposes the possibility of creating an open and free repository of open-access academic journals using Wikidata, Wikipedia, and Zotero. The project starts with only Mexican social sciences and humanities journals. To this effect, some open indices and datasets are taken as a foundation: DOAJ, Latindex, Dialnet, and Latinrev. Even though there are open datasets for academic journals, this work proposes the creation of a database based on radical openness from Wikimedia projects, following the principles of free knowledge and the participation of anyone in the construction of open science. Storing academic journals and papers in Wikipedia also allows performing analyses and cross-referencing information, which may be a complex task in other repositories. This article shows the preliminary results of analysis regarding the publishers, topics, and licenses of Mexican academic journals in the field of social sciences and humanities which have thus far been updated in Wikidata. Another aspect of this study is that it suggests that this open database for academic publications also allows indexing papers and men and women authors, as well as other topics derived from the items added, along with the use of these articles as sources or references for Wikipedia articles.

This paper presents a web application that seeks to facilitate the selection of research articles that are relevant or not to a topic. The process starts when a researcher writes a search string, which is sent to the Scopus API. With the results obtained, a grouping process is carried out to generate a visualization by groups or topics instead of the traditional ordered lists of results, making it easier for users to discard groups of articles irrelevant to their query. The proposal uses five clustering algorithms, among which Spectral and K-means exhibited the best performance in classical information retrieval metrics on four state of the art datasets. The application was assessed in two rounds by researchers of Universidad del Cauca, who, in the final round, considered that 71.4% of the clusters had a good title, 92.9% of the clusters had a good document order, and 65.8% of the articles were well clustered. The implementation of overlapping in grouping stands out since it allows articles to belong to several topics. Finally, the results are promising, and the application constitutes a valuable contribution for researchers in developing their projects. However, the results are not generalizable, and the need to create better labeling algorithms to generate more descriptive titles is evident, along with the use of tools to assist the user in query construction.

This paper presents an analysis of the state of the art regarding the typification of faults in DCU and DC, with the objective of identifying opportunities and research gaps. 20 documents were found according to the inclusion and exclusion criteria established through the methodology employed for the systematic review of the literature. Considering the relevance of the topic, it can be observed that there is limited research on fault detection in UML diagrams for both DCU and DC. [ABSTRACT FROM AUTHOR]

Every day, more technological tools emerge to aid in the management of the editorial processes carried out by a scientific journal, from the submission of a paper to its publication and follow-up of citations. However, given this increase in options, it has become more complex for those responsible to properly monitor and validate processes, as the information is more dispersed and sometimes lacks interoperability. This work proposes an architecture for integrating the essential tools of editorial flow, making an analytical and technical comparison allowing to obtain the best integration, in order to simplify the entirety of the required information in a single platform. As a result, a first prototype of the platform is presented which applies the defined architecture, obtaining favorable results for the monitoring and validation of journal works and indicators.

The Saber 5° tests seek to contribute to improving the quality of education in Colombia. Their application is periodic, they evaluate students' basic skills, and they analyze the factors that affect their achievements. This paper presents one of the results of a research work whose objective was to apply data mining techniques to detect patterns of academic performance regarding the mathematics component of the Saber 5 tests in the year 2017. This test was taken by the fifth-grade students of Colombian Primary Education institutions. To meet this objective, the CRISP-DM methodology was used. Socioeconomic, academic, and institutional information was obtained from the ICFES databases. This information was preprocessed using data cleaning and transformation techniques. The decision tree classification model was selected, as it allows easily interpreting patterns. Among the most important factors in the patterns associated with good or poor academic performance in mathematics are the nature and location of the school and whether or not the student had failed a grade. The knowledge generated in this research constitutes quality information for decision-making by the Ministry of National Education, education secretariats, and the executives of Primary Education institutions with regard to the definition of improvement plans that result in the quality of Primary Education in Colombia.

Distribution networks with transshipment are an important factor for moving of products and inputs, promoting and improving the reduction of transportation costs regarding distribution problems. This paper focuses on answering the following question based on a systematic literature review (SLR): How do transshipment distribution networks influence the reduction of transportation costs in resilient companies? A review and an estimation of preliminary research was carried out for a period of five years, operating the search engines of SciencieDirect, Redalyc, Dialnet, Scielo, and SpringerLink. The studies were selected based on a set of inclusion and exclusion criteria. It was highlighted that distribution networks with transshipment have a direct relationship with companies and aim for their well- being. On the other hand, the importance and theoretical bases of distribution networks were observed. The SLR collected clear and precise data for the study, which contributed to the understanding of the direct relationship between distribution networks and companies. The importance of logistics with transshipment in business resilience was established, which includes three basic aspects (recovery, vulnerability, and adaptation) with respect to the conditions of distribution as a contribution to sustainable development.

Currently, many studies are already available on people's theoretical knowledge about climate change. The results of some of these studies show the existence of serious confusion regarding certain phenomena and basic concepts of great importance, even despite the fact that, in recent years, the problem regarding climate change has become increasingly relevant in different media, and it is also present in school curricula as a fundamental part of Education for Sustainability. Some of these confusions constitute true alternative ideas. This paper first analyses the incidence and strength of five of these ideas in students of Compulsory Secondary Education (CSE) and in various groups of teachers in training. Then, a didactic proposal is made to achieve change in one of those ideas, which involves various concepts and principles of Physics. [ABSTRACT FROM AUTHOR]

Due to competitive markets, the software business wants faster, better, and cheaper solutions in a short amount of time. Software reuse emerges as a viable solution to these demands since it offers significant benefits, such as increased quality and efficiency and lower development costs and effort, as well as shorter commercialization times. This research aims to study and understand the state of the practice of software reuse in Colombia, to make comparisons with related works, and to offer an instrument for decision-making in companies that adopt these practices. To reach these objectives, three stages were proposed. In the first stage, the research questions were defined. In the second stage, a survey was developed, evaluated, and carried out to validate successful practices and adoption barriers in the context of the Colombian software industry. Finally, the results were analyzed and reported. This paper showed and evidenced the expectations, adoption barriers, and factors influencing the success of software reuse in Colombian industrial environments. In the same way, the experience from the development of this work serves as a roadmap for other regions that want to analyze the current state of reuse. Nevertheless, each organization needs to determine its capabilities and find the appropriate factors to be adopted to its context. [ABSTRACT FROM AUTHOR]

Boosting and developing scientific competence among students studying subjects such as Physics, is an objective currently contemplated in an explicit way in most school curricula and is shared by many experts in Science education. However, when this topic is discussed with science teachers, it is usually done by ignoring the specific contents of the subject to be taught, so that teachers can hardly transfer to their classes what has been exposed to them in terms that are too general. In our opinion, if to promote and develop scientific competence is really wanted, this must be done jointly through key content for the teaching and learning of science, such as the introduction of concepts, problem solving and laboratory experiments. The problem is that most science teachers admit that many of the methodological aspects inherent in scientific competence, such as the issuance of hypotheses, the development of strategies for their contrast, the analysis of results, etc., can be incorporated with relative ease to the experimental works, but they do not see it so clear when it concerns the introduction of theoretical concepts or the resolution of pencil and paper problems. This paper attempts to show, through the resolution of a specific Physics problem, how these essential aspects of scientific competence can be contemplated in problem solving. In addition, the possibility of incorporating practical elements and new technologies, in a functional way, into the resolution is also considered. [ABSTRACT FROM AUTHOR]

This paper presents a document classification service that allows multiple client (multi-tenant) document management systems to provide greater confidence and credibility regarding the document types assigned to documents uploaded by users. The research was carried out through the phases of CRISP-DM, where two document representation models were evaluated (bags of words with cumulative n-grams and BERT, which was recently proposed by Google) and five machine learning techniques (multilayer perceptron, random forests, k-nearest neighbors, decision trees, and naïve bayes). The experiments were carried out with data from two organizations, and the best results were obtained by multilayer perceptron, random forests, and k-nearest neighbors, which showed very similar results regarding general accuracy and recall by class. The results are not conclusive with respect to the ability to offer the service to multiple clients with a single model, since this also depends on their documents and document types. Therefore, a service is offered which is based on a microservices architecture that allows each organization to create its own model, monitor its performance in production, and update it when performance is not adequate.

This paper presents the results of a study conducted with a group of natural science teachers in service of Institución Educativa Libertad (Pasto, Nariño). Its objective was to analyze the design of activities elaborated by teachers when explaining the combustion phenomenon in the context of a school, making use of the Faraday’s The chemical history of a candle, a historical case. The methodology is qualitative, with an interpretative approach and a multiple case study. A professional development community (PRODEC) was created with the teachers, who participated in teacher training workshops. The survey and the written production of the designs created by the teachers were used as instruments. The information was systematized with Atlas.ti, and the explanations from the content analysis were studied according to four categories: contextual elements, structuring, transference, and metacognitive reflection. It was evident that the contributions of the historical case in the construction of explanations were oriented in two directions: the first, with respect to the explanation of the combustion phenomenon in the classroom; and the second, regarding the strategies for the explanation of science to young people.

However, searching for software components on GitHub is currently inefficient, as searches are based on text strings. This paper introduces OntoGitHubSearch as a search model that allows the retrieval and classification of software architectures stored on GitHub. This proposed model retrieves all repositories that match the searched architectural concepts; to provide the search with semantics and context, it implements the domainspecific ontology Architecture Ontology Version 2.0, as well as a natural language processing module to analyze the text in the repository. The repositories are automatically identified and classified according to the text and concepts found in their descriptions. To evaluate the proposed model, we developed a web application called WebOntoGitHubSearch, which allows interaction with users during the search process. The evaluation of the model was carried out with the participation of software developers and architects from several colombian businesses. Information retrieval metrics such as Precision at k. The results obtained during the evaluation process are promising and allow verifying the effectiveness of the proposed model. [ABSTRACT FROM AUTHOR]

Problem-based learning (PBL) is a didactic strategy oriented to the competency-based approach within constructivist theories. PBL generates a collaborative learning process in the student, as well as self-learning and meaningful learning from a contextualized problem situation. This methodology arises to support the process of pedagogical change that occurs under the competency-based approach in higher education in order to generate active learning in students. In this paper, a five-phase methodology was developed (identification of the problem situation, organization of the work for collaborative learning, monitoring and support for self-learning, construction of applied solutions, and evaluations and feedback) to apply PBL in the Supply Chain Management course of the Industrial Engineering Program at Corporación Universitaria del Caribe (CECAR). A systematic literature review was carried out to identify the low application rate of the methodology in the field of industrial engineering. For the application of the strategy, three contextualized problems were taken as a basis, which are associated with companies of the economic sectors that have the highest influence in the generation of the Gross Domestic Product (GDP) of the region. The academic impact on a total of four groups was evaluated. Additionally, the expected competences, performances, and products in the courses were achieved, thus obtaining a great acceptance and efficiency in PBL application. [ABSTRACT FROM AUTHOR]

This paper presents the implementation outcomes of the Equivalent Circuit Model (ECM) acting in conjunction with the Matrix Cascading Method (MCM) for bandwidth calculation in cross dipole Frequency Selective Surfaces (FSSs). Dielectric layers are used as a support of resonant elements in FSSs. Models of effective permittivity of the dielectric layers in FSSs allow to determine the effect of the material used as insulating support of the resonant elements, in relation to the resonant frequency and bandwidth, as a function of the thickness of the dielectric material. However, in this approach, the insulating support is considered as thin dielectric, and therefore, it is modeled as a lumped parameter. This consideration may lead to unsuitable results in calculating the bandwidth for thick dielectric supports. The novelty of the paper is the implementation of the Equivalent Circuit Model together with the Matrix Cascading Method to determine the frequency response of the cross dipole selective surface for any dielectric thickness and configuration. It is notable the low computational time as well as the acceptable accuracy obtained with the proposed approach, compared to Ansys-HFSS simulations. [ABSTRACT FROM AUTHOR]

For the exchange or loan of educational resources at the inter-institutional level, both public and private entities have their own procedures and specifications, being common in all the long period of time required for the approval of a loan and the need to move to said institution to perform the query according to the availability of defined time. The objective of this paper is to present a software design that allows the transaction of academic resources between two educational entities, in order to reduce time in the execution of the process. The implementation of the model is based on the proposed stages of the Scientific Method and the Unified Process, applying electronic negotiation specifications defined in ebXML, to define, through agreements and profiles, conditions of use of the requested resource. By implementing the software model, the execution times of the business process from several months to a couple of minutes are shortened when all the exchange is carried out by electronic means, in addition to communication without geographical limitations, favoring both students and entities for the exchange of intellectual property remotely.

The computer process that helps cover tax evasion can be improved through digital analysis as reflected in the findings of evidence of the use of forensic laboratories. [ABSTRACT FROM AUTHOR]

The design of the roller coaster involves a sequence of curves that must be connected smoothly; whose parameterization enables the study of its properties. In this paper we study the curvature of the trajectory that a vehicle would follow in mechanical attraction. The discontinuous changes in the curvature along the trajectory imply changes in the normal acceleration that could be unsafe for the passengers, and then a parameterization for a trajectory whose curvature is continuous was sought. When we consider a trajectory whose curvature changes linearly with the displacement, it is found that the Euler spiral allows smoothly connecting different segments of the trajectory and describing safer mechanical attractions. Finally, the parameterization obtained is compared with the trajectory of the Double Loop attraction in the Salitre Mágico amusement park in Bogota, finding that its path is formed by sequences of circumference arcs and sections of the Euler spiral.

In this paper we review the problem of teleological conceptions in the teaching and learning of evolutionary biology. We characterize what we call the "traditional perspective" in relation to this problem and question the epistemological and psychological-didactic assumptions on which it is based. Against this traditional perspective, based on the objective of eliminating teleological reasoning and the censorship of their expressions, we offer an alternative perspective based on the development, on the part of students, of the ability to regulate consciously and intentionally the recourse to teleological reasoning and expressions. We also offer some guidelines for the design of specific teaching activities in relation to this objective. [ABSTRACT FROM AUTHOR]

In this paper is carried out a first approximation to anxiety surrounding situations related to science. One hundred and seventy-five spanish secondary education students at different educational levels have been administered two validated tests and a scientific competencies assessment test. One test measures the anxiety caused by scientific contexts, and the other test assesses the science assessment test anxiety. The analysis of the results obtained by means of Anova tests allow us to conclude that: a) the anxiety in scientific situations is greater than the non-scientific situations, and this anxiety gets smaller as the school grade level increases. ; b) the science assessment test anxiety is statistically significantly higher for women than for men; and c) there is no evidence of a significant correlation between the science assessment test anxiety and science test scores.

Science Education today can be considered as a whole and coherent body of specific knowledge with a "hard core" in which the most directly issues related to key aspects of teaching and learning can be found. The appropriation of this knowledge by teachers is required in order to move towards a higher quality teaching in the field of the experimental sciences. However, this appropriation is not an easy task, and requires overcoming a number of problems which must be taken into account. In this paper, some of these problems are discussed, and some proposals to make progress in solving them are justified. [ABSTRACT FROM AUTHOR]

Farmers in Norte de Santander department supervise the microclimate in greenhouses by an intuitive estimation based on their long time experience. This method is inadequate and subjective, and it has a negative impact on the development and performance of the crops; limiting the quality and production. Therefore, this agricultural procedure requires the development and implementation of efficient technology aiming to the improvement of the production. For small- scale farmers is difficult to acquire supervision systems due to their low income and the relative high cost of this kind of technology; then, farmers prefer to prescind from the advantages of using monitoring systems in greenhouses. This paper presents the design and development of a low-cost modular system that allows the supervision of environmental variables within a greenhouse. The proposed system uses ZigBee protocol and a Wireless Sensor Network to collect data of humidity, temperature and luminosity; these variables are stored in a database and the system shows a real time plot and allows to generate reports. The Packet Reception Rate obtained in the experimental setup was between 70 % and 100 %. Besides, the proposed system has a reduction in cost of about 87 % with respect to commercial systems with similar features. [ABSTRACT FROM AUTHOR]

This paper presents the findings from the assessment of an activity for learning some nature of science (NOS) aspects using as context the historical case of Semmelweis' research on childbed fever. The activity is intended for 15-16-year-old students and it was performed from an explicit and reflective approach. A rubric was employed to assess students' learning, which was applied using a method of inter-rate analysis. Also, the teacher's diary was used as a complementary tool of assessment. Globally, the findings show students' progression in understanding the aspects of NOS addressed. The students attained a moderate level of understanding in relation to epistemic aspects, but their levels of understanding were higher regarding the non-epistemic. Therefore, the pedagogical potential of the activity for learning on NOS is evidenced. Finally, some educational implications of the experience are proposed. [ABSTRACT FROM AUTHOR]

We study the dynamics of nonlinear pendulum, which consists of a particle of mass m attached to the end of a light inextensible string of length l. Therefore we plot the variation of pendulum potential energy function of angle, as the corresponding phase diagram. The conditions imposed determine the behavior of the pendulum so that there is an oscillating movement and rotation, dependent on the value the maximum energy and potential energy is determined. As a case study the oscillator movement, analytically solve the differential equation of second order with reference Beléndez paper, we get results when the system initially presents a nonzero angular velocity, (dθ/dt)|t=0 = φ0. The solutions obtained for the angular displacement versus time is in terms of the Jacobi elliptic functions sn (u,m), we plot the angular displacement when the initial angular velocity is equal and non-zero. The results agree with those reported in Beléndez. The problem can be used to introduce concepts of elliptic integrals and motivate students to using computer software to analyze the solutions obtained. [ABSTRACT FROM AUTHOR]

As a result of the qualitative analysis, documented through interviews and surveys, a process description, process flow and diagram interaction inputs, techniques and outputs is proposed, for the identification, documentation, analysis and application of lessons learned, looking for a standardized guide to run this process within the modern project management framework. This approach aims to contribute to sector growth and competitiveness, and process effectiveness improvement, using learning-based experiences. [ABSTRACT FROM AUTHOR]

There are different standards focused on project management. Examples of these standards are the PMBOK Guide and PRINCE2 method. In this paper it is made a comparative analysis of the PMBOK Guide in relation to PRINCE2 structured method, based on the assessment of different literature sources. During the course of the investigation different theoretical elements of both PMBOK and PRINCE2 were analyzed, such as the origin, evolution, structure and application, allowing the identification of similarities and differences between them. The result of this research reveals that these standards are not considered mutually exclusive and that can coexist on the same project. PRINCE2 determines what, how, when and by whom the activities will be implemented using a common language easily assimilated and PMBOK is an international reference guide that incorporates a wide range of knowledge about project management.
