In the educational context, gamification has emerged as an effective strategy to enhance learning and motivation. With the rise of information and communication technologies, digital gamification (DG) has emerged. Although there are numerous studies summarizing the contributions of gamification in education, very few have included preschool education. The present systematic review, supported by 25 primary studies published between 2014 and 2022 and indexed in Scopus and Web of Sciences, seeks to close this gap by characterizing the main contributions, and qualitatively synthesizing the effects of DG. The results indicate that there is a growing interest in the topic, where most of the studies originate in Asia; they are published in journals; and are based on the proposal of video games for computers or mobile devices that seek to improve language learning. Narrative approach research predominates, based on samples of less than 10 participants, employing Achievement (Progression) type game elements. The 15 studies that measured the effect of DG report positive results.

Timber residues due to its use for the construction industry and others provided by the secondary forest and its high content of lignocellulosic material for energy purposes, our objective was to evaluate the forest residues of six species to obtain carbon as clean energy, which represents great interest for the energy industry. Through the methodology of the study of inventories and sampling of wood residues from sawmills that was in the four cantons of the province of Pastaza, through instrumental techniques of physical, chemical and thermal analysis, the parameters studied were the biomass potential and residue, density, humidity, ashes, volatiles, fixed carbon and higher calorific value (immediate analysis), carbon, hydrogen, oxygen, nitrogen and sulfur (CHONS), which allowed obtaining the thermochemical properties, reaching the main results of energy potential, of these three species that can be used for clean energy, due to the amount of ash found in the analyzes below 1 % and volatiles (60-80 %) of these residues, which clearly shows that it prevents the formation of scale in equipment and damage, in relation to its fixed carbon content on average of 14.78 % and its superior calorific value 19.72 Mj/kg, assessing the fact industrial reliability for its energy use that will generate 515.62 GW of clean energy in electrical thermal power annually to meet the needs of vulnerable areas of the Amazon region.

Peruvian aquaculture is booming, so it deserves to be technified from a sustainable and competitive perspective. The objective of the review was to identify the current panorama of Peruvian aquaculture and the factors that limit its development, as well as to analyze the benefits of the use of technological tools in aquaculture. To this end, a review methodology was applied based on three phases: i) development of the research question; ii) document search; and ii) review and selection of studies. The search engine used was Google Scholar, Scopus, ScienceDirect, Web of Science (WOS), Scielo and Redalyc databases. The review showed that aquaculture in Peru is developed in few regions and with few species. According to PNIPA, the factors limiting its development are related to noncompliance with current sanitary regulations, vessels that are not registered in public registries, and the absence of accreditation controls for artisanal fishermen. Technification of the feeding process reduces operating costs. Sensors make it possible to visualize the variation of parameters in real time, reducing the fish mortality rate. Automatic counting and classification reduces fish stress and avoids economic damage to production. The conclusion is that, in order to achieve aquaculture technification, the government and producers must work together, implementing policies and strategies that guarantee greater profitability and sustainability over time.
