Objective: To determine the influence produced by learning activities according to the fundamentals of user-centered design, in the formation and assimilation of mathematical concepts of future applied mathematics professionals at the José Faustino Sánchez Carrión National University, on the subject of functions. of a real variable. Methodology: The research is quantitative, quasi-experimental, longitudinal, prospective. The study sample included 30 students, from the I cycle enrolled in the academic semester 2021-I and 2021-II of the professional school of mathematics, divided into two groups: A (experimental group) and B (control group), had a duration of 16 weeks; the instruments used were two achievement tests that measured the level of understanding of the concept of function. For data analysis, the measures of centrality and the Student's t-test were used. The analysis of the measurements of the dependent variable (conceptualization of the topic of functions of a real variable), before and after the experimental treatment (design of learning activities according to the principles of User Centered Design), confirmed the general objective of the investigation when comparing the values obtained and when using the t Student test with a significance level of 0,05. Conclusions: The findings indicate that the design of the concept of function based on User Centered Design promotes in the student the representative and articulated construction of its meaning through an operational system of learning experiences.

Objective: To determine the relationship of intertextuality and production of texts in the students of the I and IX cycle of the Physical Education and Sports career of the José Faustino Sánchez Carrión-Huacho University, Material and Methods: The research was developed using the correlational design , descriptive, transversal, in the search for the relationship of intertextuality and production of texts in the students, with a population of 69 students of the I and IX cycle of the Physical Education and Sports career, as a selected sample it corresponds to the total of representative students of the study population. Result: The intertextuality and production of texts are significantly positively related in the students of the I and IX cycle of the Physical Education and Sports career. Conclusion: There is no text without the derivation of another text, intertextuality is a social historical product, its operation is not only in literature but also in other texts whose analysis is hermeneutic.

Objectives: To determine how the natural and cultural resources of the Andean districts of the province of Huaura shape their geoturistic potential. Materials and Methods: Qualitative, non-experimental and exploratory, descriptive and explanatory approach; The natural elements or geoforms and the most significant cultural expressions that make up the geoturistic potential of the Andean districts such as Amber, Checras, Leoncio Prado, Paccho, Santa Leonor and Sayán of the province of Huaura are considered, both as population and sample. Bibliographic, hemographic and documentary research used from public and private repositories in Lima; collection of observation sheets of the natural and cultural resources of each of the Andean districts of the province of Huaura, collection of testimonies and audiovisual records, application of interviews and questionnaires to valid authorities and informants. Results: The natural and cultural resources of the Andean districts of the province of Huaura, contribute to the geoturistic potential; they have conditions to facilitate the Rural Community Tourism (TRC), mainly taking advantage of the forms of organization in rural communities of the population, the practices of adventure tourism, ecological, ecotourism and mountaineering that, properly oriented, become opportunities for development sustainable. Conclusions: The Andean districts of the province of Huaura have conditions to facilitate the development of rural tourism in its various expressions, taking advantage of its attractions. The natural and cultural resources of the Andean districts of the province of Huaura can be used as a geotouristic resource and contribute to their economic development. All these resources, natural and cultural, to be identified, rescued, conserved and revalued by rural villages can allow you to move forward despite the lack of infrastructure to develop tourism activity; and then progress little by little as it already glimpses.

Objective: To determine if stress is related to the job performance of administrative workers in the University Welfare Office of the José Faustino Sánchez Carrión National University - Huacho 2018; Method and Material: The study population is made up of the administrative workers of the University Welfare Office. It is then a limited population. Counting this area with 23 workers covering administrative and chiefs; As instruments of data collection, the survey was applied; which contained 25 questions regarding the variable Stress and Work Performance. The anonymous character of the form was highlighted, as well as the sincerity of the answers issued to contribute to the success of the study. Results: They show that the main sources of stress in the workplace are mainly due to extra-employment risk factors such as economic situation, family problems and time away from work. These factors would be improved if companies assume clear policies of social responsibility. Conclusion: The present work established the significant relationship of Stress and Labor Performance, at the same time by calculating the Pearson Correlation it was established that Work Stress significantly affects the performance of administrative workers of the University Welfare Office and that This is due to the determination of different Stress factors.

Objective: To determine how the lack of a business strategy influences the growth and development of small and medium-sized companies in Peru. Method: The population was made up of 100 small and medium-sized companies in Peru. Measurement instruments that have been validated by experts were used. The research is Descriptive - Correlational level. Result: 63% of the Managers surveyed express that they almost always apply business strategies, 6% apply the various strategies in their companies and 4% express that they never use the various business strategies in their companies. 56% of the Managers state that they almost always have business growth, 31% express that they sometimes have business growth and 13% express that their small and medium-sized companies are always improving. 50% indicate that sometimes the financial system improves, 46% almost always improves the financial system in their companies, but it must be considered that the design increases and 4% state that the financial system of their small and medium-sized companies almost never improves. Conclusions: Regarding whether the business strategy influences the growth of small and medium-sized companies, they consider that managers do apply the strategies to seek growth but they do so in a very difficult way, which shows that their results do not they are efficient. In this respect, we also have that a small percentage do not apply the strategies for the companies, which is proven by the low performance. We have that a sector considers that the strategies if they improve the financial profitability of the company.

Objectives: To improve the extraction of juice in the mills and to decrease the humidity andbagasse pol in the area of trapiche. Methods: Type of research: applied - technological. Thepopulation consisted of all level control systems. The sample was Level Control System basedon a PID controller. A data record sheet for mills was developed as a data collection tool.Results: Configuring parameters for the mill level control system was achieved. It decreased%pol of bagasse by 0.23 and %humidity of bagasse by 0.4 percentage points. Combustion inthe boiler and hence sugar production were improved. Conclusions: The configuration ofparameters of the PID controller improves the level control system while maintaining an optimalcontrol of shredded rod load within each chute. It was possible to optimize the extractionprocess of cane juice and therefore to reduce the percentage of pol and humidity in thebagasse, thus improving the combustion of the boiler.

The present study entitled “Relationship between preprofessional pedagogical practices and knowledge about the 2017 National Curriculum in the students of the Manuel Gonzales Prada Higher Pedagogical Institute, Lima, 2018”, had as its main objective to determine the relationship between preprofessional pedagogical practices and knowledge on the 2017 National Curriculum, to achieve this objective, the methodology called quantitative was followed, which includes a set of activities and procedures that show the intention of the research through the operationalization of the variables involved and the presentation of data statistics such as pie charts and frequency tables. The research design is non-experimental, that is, descriptive correlational. The population was formed by all the peer cycles of said institute, giving a total of 120 students. As a result, it was shown that, in the hypothesis initially proposed, “there is a linear, direct and significant relationship between pre-professional practices and knowledge about the 2017 National Curriculum”.

The post-catastrophe image, from the architectural-urban point of view, is the reflection of socio-spatial dynamics related to complex phenomena. Since the last century, the disasters have been researched in a profound way from a mainly disciplinary point of view. The studies have focused to predict the events and on a methodological work of post-event solutions. This situation is highly complex, where converge multiple factors that define the emergency reality. The analysis and strategies of interventions have focused on static approaches to urban recovery and re-habilitation or ex-novo construction of specific works, that have not solved the real problems that arise in a post-catastrophe situation and It is not been defined a criterion on the landscape of these conditions that can answer the question: what is the representation of the image in this type of socio-spatial configurations? The present article wants to define the concept of "landscape of post-catastrophe reconstruction" so that the framing of the issue is about the process (dynamic framework) and not about the object (static framework). This has materialized, at the methodological level, through interviews with the community and two in situ surveys of the built park and the urban system of San José de Chamanga, emblematic place of the province of Esmeraldas in Ecuador. The results lead to the definition of two types of landscapes that show the need not to intervene with accurate and permanent zoning, but with process models that are adaptable to the changing environment.

In 2020, the WHO declared a global pandemic due to the SARS-CoV-2 virus, which forced educational spaces to continue in virtual mode. The objective of the study was to investigate the most used ICTs for the transmission of practical knowledge and to identify which presented the best results in students in health areas. Narrative review of secondary sources was used as a method, for which eleven articles were identified and analyzed in the PubMed and Google Scholar databases. As outstanding results, it was found that the students did not accept that virtuality provided them with the acquisition of practical skills that they would acquire in real scenarios, but, if there was a good acceptance in the theoretical subjects, which allows us to conclude that virtuality was a good option in the health emergency to continue with education, however, there are multiple factors that reveal the inefficiency in the acquisition of practical skills.
