The research focuses on the Natural Wetlands of Villa Chorrillos located in the district of Chorrillos, in Lima, Peru; whose objective was to determine the association between urban expansion and the sustainability of these wetlands during the period 2010-2020. In this way, it seeks to sensitize those involved, be they expert authorities and the community in general, to reinforce and internalize the issue of environmental education. The approached methodology was observational and transversal in nature, which allowed the collection of images that support the invasion and expansion of the urban that deteriorate nature. On the other hand, a questionnaire with 27 structured questions with qualitative variables and three response options was developed. The results both at the descriptive level characterized the dimensions and indicators of their respective variables, as well as their correlation, proposing 3 hypotheses between the spatial dimension versus the economic, social and environmental dimensions. With 4 degrees of freedom and 0.05 significance, an inferential decision was made regarding the accepted or rejected hypotheses. The conclusion is that the spatial dimension and the environmental dimension of the natural wetlands of Villa Chorrillos for the period 2010-2020 are significantly related.

The purpose of the study was to describe the methodological competence in teachers and university students through training instructions from the research incubators. From June to September 2021, the project of research incubators "training and training" was carried out for teachers and students of the National University "San Luis Gonzaga", Ica (Peru). The academic area of the study was Pharmacy and Biochemistry. Based on the conceptualization for methodological competences, three levels of training instructions were considered: I) identification of what to do, II) execution of what to do and III), communication of what to do. A development model was proposed that consisted of five instructions: title, introduction, objectives, measurement and proposed improvement according to the undesired situation. The students were able to complete the proposed development model, based on creative learning and team exchange together with their tutors. The development model of the research incubator showed a pedagogical strategy of evidence of methodological skills from the university teacher and contributes to the satisfaction and improvement of academic performance in students.

There is a latent problem in the agricultural sector in the cultivation of potatoes since it is not always profitable for farmers because its sale price not only depends on the amount of product offered in the market and the demand by the consumers but, of the possibility that they themselves carry out their commercialization. This aspect is analyzed in this research, whose objective was to explain the reasons why the commercialization of potatoes affects the economy of peasant families in the following provinces: Tayacaja (Huancavelica) and Huancayo (Junín). The research was of a basic type with a descriptive-explanatory level with a non-experimental-longitudinal design. The population was made up of 120 peasant families that produce and market potatoes from the provinces of Tayacaja and Huancayo, from which a sample of 91 families was drawn. Documentary analysis guides, bibliographic records and a questionnaire were used as instruments for the field work. It was found through the application of econometric models that 79% of the respondents accept that the sale price of the potato influences the economy of the peasant families of the provinces under study since it is very low and does not allow obtaining economic income and that the lack of storage of the potato to be commercialized affects the economy of the peasant families of these provinces because the product is lost and this generates economic damage

Technological progress develops industrial processes that impact the environment with the generation of waste. In the Mantaro river basin, the waters are contaminated by mining and surrounding populations. The National Water Authority (ANA) reports that at point RMant 12 an increase in manganese values is observed in its waters. at 200m Upstream is the intake of the agricultural irrigation channel left bank of the Mantaro Valley (RMBT), a reference point for the investigation. The objective of this study is to mitigate the manganese content with respect to the ECA 3 standards (0.20 mg/L). The investigation carried out in the laboratory demonstrated, in the case of synthetic water, a mitigation of 55% for the manganese content with the treatment of clinoptilolite-type zeolites. In the practice of the treatment carried out under the same conditions for the samples of water contaminated with manganese from the Mantaro River, the manganese content decreased by 32%. It is concluded that manganese mitigation has been carried out according to adsorption by zeolites, in multilayers according to Freundlich. Research on clinoptilolite is recommended to integrate it into decontamination methods for rivers in our country.

With this letter, we will try to provide new information regarding the origin of SARS-Cov-2, reviewing information published after volume 8 of your magazine. The Covid 19 pandemic produced by SARSCoV- 2 has produced to date more than 130 million fixes and 2,700,000 deaths globally causing collapse health and economic (Cabezas 2020). In the review article "Zoonotic links of the SARS-CoV-2 coronavirus", Vol. 8 No. 1 page 68 (Iannacone et al 2020), it is said that this disease has as a background the epidemics of the Syndrome Severe Acute Respiratory Syndrome (SARS) and Middle East Respiratory Syndrome (MERS) and in both the source of the virus or reservoir is the bat and its intermediate hosts are the Palm Civet in the case of SARS and the camel in the case of MERS (Ye et al., 2020) and in terms of SARS-CoV-2, it is postulated that its reservoir is the bats of the genus Rhinolophus affinis Horsfield (Zhou et al., 2020).

The present research aims to provide updated information on passive heating systems in Perú and to establish which are the most optimal passive heating strategies that have achieved an improvement in indoor thermal comfort in high Andean homes. A review of articles from the scientific literature specialized in the area of passive heating systems applied to high Andean homes in the highlands of Peru that are located within the range of 3 000 to 5 000 meters above sea level, which are characterized by having a cold climate and also be exposed to the problem of frosts typical of these places. The results of these articles show that the most efficient passive heating systems or strategies achieved an increase in the interior temperature by 9.5°C on average, not being enough to achieve thermal comfort in high Andean homes, but that they are favorable because they achieve improve the feeling of well-being of users.

In the letter we provide an update regarding the zoonotic role of SARS-CoV-2 (Severe Acute Respiratory Syndrome 2), especially when analyzing the letter entitled: "Current and controversies of zoonosis as the origin of SARS-CoV-2" (Mirror -Sotelo & Tello-Arquiñego, 2021), which analyzes and updates the review article "Zoonotic links of the SARS-CoV-2 coronavirus" (Iannacone et al., 2020). In the aforementioned letter, interesting contributions are mentioned in relation to the theme. However, as of June 2022, controversial conclusions continue to be drawn regarding the issue.

We evaluated the effect of an assertiveness workshop focused on Acceptance and Commitment therapy (ACT) aimed at parents in achieving change in their children's aggressive behavior compared to a standard Cognitive-Behavioral intervention (CBT), that is, find out if an intervention based on ACT or a standard Cognitive-behavioral treatment is more effective, from a statistical analysis point of view, as well as its clinical relevance. The experimental population consisted of 15 parents, divided into three groups: control, ACT and CBT. An A-B univariate multiconditional multigroup experimental design was used. In the ACT workshop, training was proposed for parents on how to manage child behavior through assertiveness guidelines under the contextual therapeutic model, throughout sessions planned under the three basic components of this intervention: acceptance, values and distance.The results showed that the subjects who received the ACT workshop modified inappropriate behaviors, however, no significant differences were found between the CBT and ACT groups.

This health crisis, in addition to showing the precarious health system, has shown that the machismo that prevails in Peru is as serious as this pandemic; however, it has not been given due attention. In this way, it is considered essential to perceive how this state of emergency, as a risk factor, has reinforced sexist behaviors and gender roles in Peruvian society, and, at the same time, reflect on how this should be an opportunity to question and deconstruct society. The objective of this article is to analyze the elements to reflect on the COVID-19 pandemic from the point of view of masculinity and how these can provide tools to face this situation. Likewise, face it not only in a positive way but also proactively from a future perspective in which the practices are translated into cultures where care, peace, affection and equality are central elements in the lives of men
