In a digital world, which is evolving more and more rapidly towards the culture of the visual, acquiring visual literacy tools can be essential, especially for the professional future of university students. Art education manages to enhance the development of visual learning and motivate the student in their process of analysis, discovery, understanding, assessment and apprehension of the visual arts. The use of the image as a teaching tool in the classroom favours the progress of critical and reflective observation and promotes expressive skills. The objective of this work was to present experiences on visual learning in Art Education in university contexts. A systematic review of the literature was carried out during 1990 to 2020. The results allowed us to recognize the main author agents, their research tendencies, and reveal certain gaps in critical knowledge. Research findings and trends converge on the advantages of incorporating visual resources in higher education, emphasizing the importance of sensory approaches to support learning.

The objective of this study was to design and validate an Augmented Gamified Environment (AGE) for improving communicative skills in students with ASD. The study used a mixed methodology: a) qualitative, focused on a single case to describe the AGE design process. The environment uses a pirate adventure story which includes gamified activities supported by augmented reality. It promotes immersive learning through activities that encourage social, linguistic, and cognitive skills linked to symbolic play; and b) quantitative, based on the Delphi method in which experts (N=12) evaluated the environment using 14 indicators in four dimensions: adaptability to the pace of learning, suitability of the base and code for presenting the content, didactic potential for developing competence, and the suitability of the gamification process for students with ASD. The expert assessment helped to improve the adaptability, flexibility, and functionality of the AGE, which incorporated versatile and augmented reality activities and applications to provide the student with playful linguistic and socio-emotional development in an immersive environment.

Currently, educational innovation is an unavoidable premise for teachers, school headteachers and families. This contribution aims to provide better understanding of the configuration of pro-innovation discourses from a lexicometric perspective. To this end, we applied various textual statistical strategies to the analysis of a corpus made up of twelve verbal texts from four discursive fields: the education policy, the school, the Social Sciences Department and the Geography and History class in which, finally, pro-innovation discourses become practices. The results obtained, which focus on the discursive associations of innovation (collocations, combinations, concordances and co-occurrences), indicate that the meaning of educational innovation is taken for granted, that it has only positive connotations and that it functions as an argument to justify educational reform. In addition, it is noted that innovation is especially linked to new technologies and business vocabulary. We conclude this paper with a defence of the usefulness of the techniques used, but also with a warning of the need to complement the analysis carried out with other linguistic and interpretative techniques.

In a global scenario characterized by a deep economic recession and tourism among the most affected sectors, the competitiveness of the sector will depend on the performance of the enterprises that interact in each of the destinations. From the analysis of the Cuban enterprise environment, it was possible to identify that in the Higher Organization of Enterprise Management Viajes Cuba there is a need for the evaluation of the competitiveness of travel agencies and it is evident that there is a shortage of research in this regard. In response, the present research proposes as general objective: to elaborate a procedure that allows the evaluation of competitiveness in the agencies that integrate this organization. The methodology applied consists of four phases that combine different tools, methods and techniques for obtaining and processing information. This led to the following results: the research analyzed is limited in terms of the development of the competitive study, the proposed indicators and their approach. The established procedure will reflect the competitive situation of the travel agency under study and its dimensions in order to influence the most affected ones, while the aspects that make it up were evaluated as very adequate, according to the experts' criteria.

In September 2015, the Sustainable Development Goals were approved, giving way to the previous agenda: The Millennium Development Goals. At the halfway point of the date for their achievement in 2030, it is necessary to reflect on the setbacks and advances of the Agenda. Specifically, the objective of this article is to analyze the implementation of the Sustainable Development Goals in the achievement of gender equity in the Latin American and Caribbean region. Specifically, it will address the situation of women's economic autonomy, addressing Goals 1, 5 and 8. The methodology used is through qualitative review, applying theoretical methods of a socio-legal nature and through the analysis-synthesis of the data obtained. To this end, this will be studied through two axes, on the one hand, the data collected from the region around the selected goals and indicators; and, on the other, the development of innovative legal norms. In this sense, although there have been some advances that allow the 2030 Agenda on a path of progress, the pandemic crisis has revealed the structural conditions of gender inequality, making it necessary to reflect on the crisis of care in the region. The pandemic crisis has shown several setbacks, but a positive trend can be indicated in the approval of comprehensive regulatory frameworks in the region, which shows the interest in making feminized and unpaid work visible, but these must be accompanied by a real political commitment.

The objective of this study was to evaluate the incidence of roasting temperature (120, 130 and 140 °C) on the physical-chemical characteristics and husk alkaloids of three cocoa varieties (Forastero, Trinitario and CCN51) and their effect on the organoleptic properties of an infusion. The evaluation of the physical-chemical characteristics (humidity, pH and titratable acidity) was carried out according to INEN standards: 1676:2013; 1842:2013 and 381 respectively and alkaloid analysis (theobromine and caffeine) according to the reference method AOAC 980.14-1998, regarding the organoleptic analysis a 9-point hedonic test was used. This allowed determining that the roasting temperature significantly influences the physical-chemical characteristics and emphasizes that the values of the evaluated parameters decrease as the temperature rises. For alkaloids, it was shown that the type of cocoa husk had an impact on the content. In addition, high roasting temperature reduces theobromine and considerably increases caffeine. For the organoleptic analysis, it was determined that T1 (Forastero + 120 °C) obtained the highest scores in aroma, flavor and acceptability; in relation to color, T4 (Trinitario + 120 °C) stood out with the highest score. Thus, it is attributed that the presence of bitter, acid and astringent flavors in the husk is due to temperatures greater than or equal to 140 °C.      

Wheat is the most imported cereal in Peru for the flour industry. The use of flours made up of flours from local crops as seeds and tubers that provide nutrients, which, replacing them totally or partially, will reduce the gap in wheat imports. Colocasia esculenta puree was obtained with which wheat flour was partially substituted, using the sponge method. The substitutions were: 10%, 15%, 20% and 30%. Subsequently, the obtained breads were evaluated using a hedonic scale, physicochemical and microbiological analysis. The hedonic sensory evaluation led the semi-trained panelists to accept the substituted formulation with 30% puree, since it presented better sensory attributes in color, flavor, texture, appearance and acceptance (p < 0.05). The physicochemical results of the accepted formulation revealed better nutritional contributions (307.7 kcal, 11.37% protein, 2.5% lipids, 59.93% carbohydrates, 0.56 fiber and 1.5% ash), microbiologically it resulted be suitable for human consumption as indicated by RM 591-2008/MINSA-Peru (Criterion VIII. 1- commercial French bread) and NTP: 004 2016/INACAL, therefore the present study revealed that the use of mashed potatoes Pituca can be used as an alternative substitute for wheat flour in baking.  

The research proposes a hydrological model to forecast recessive flows and it estimates a depletion coefficient for the "Jequetepeque" river, water from the top of the "Gallito Ciego", Contumazá, Peru. Recessive flows were used from the third break point of the flow hydrograph of the "Yonán" station of the "Jequetepeque" river, period 1988 - 2019. An exponential category hydrological model (ALVI) was used. Ranges of depletion coefficients 0.0148 < α < 0.0003 day-1, and a calibration coefficient of 0.005 day-1 were identified. The proposed model, ALVI, was validated, and it is based on statistical indicators, such as: NS (0.84), RMSE (0.62), R2 (0.97), EEE (0.66) and IWM (0.84). The statistical indicators indicated a high degree of efficiency, it is inside within the metric of the ranges of the statistical indicators. The hydrological model (ALVI) was validated: Qb = Q0 / (1+e [1.32*Ln ((Q0/Qf) -1) - (0.003*Ln(A)+0.0057)*t]). The observed and simulated flows were identical to the non-parametric Mann-Whitney U test. The RStudio Cloud program was used with a significance level of 0.05, it was determined from the median that the observed and simulated flows are similar or identical.  

The production of coal from biomass emerges as a sustainable alternative, both to take advantage of waste and to protect the environment. This research aims to take advantage of aguaje seeds to make ecochar. First, the seeds (from Pucallpa and Yurimaguas) were characterized proximally. They were then characterized morphologically (length, diameter, and weight), both fresh and dehydrated. In the second part, the carbonization was carried out, using a Completely Random Design with factorial arrangement. The first factor was the state of the seed (fresh and dehydrated), and the second was the carbonization method (open and boxed), the response variable being yield. In the third stage, briquettes were made, mainly evaluating the calorific value. The results showed that solar dehydration similarly reduced the weight of the seeds. The state of the seed and the carbonization method have a significant effect on the yield, being the best treatment with dry seed and open carbonization (yield 25.77%). This treatment also obtained the highest calorific value (6716.93 cal/g) in the final briquettes, higher by almost 25% than that of traditional briquettes.
