The Babahoyo River sub-basin is part of the Guayas River basin hydrography, as the Babahoyo River, and the Daule River, are the two tributaries forming the great Guayas River. This sub-basin covers the eastern part of Los Ríos province, in an area of 2,940.18 km2, representing 41.90% of the total area of the Babahoyo River sub-basin. The weather in the Babahoyo River sub-basin is characterized by an annual average temperature of 25.5° C, with 83% of relative humidity, 1,050 hours of sunshine, 1.3 m/s wind speed, and 2,200 millimetres of rain precipitation. Agriculture is the main economic activity and production source of the Babahoyo River sub-basin. Single-use soils occupy 37% of the surface, while coverings and associated uses correspond to 47%; other types of coverings such as populated settlements, natural and intervened forests, transitory crops, bodies of water, among others occupy 16% of the area. The proposal considers, among other things, the promotion of intensive environmental education, proper livestock management, water quality, biological, and genetic diversity conservation; as well as the replacement of conventional agriculture by sustainable agriculture that involves agroecological practices in crop systems. This study aimed to characterize and propose the agroecological management of the Babahoyo River sub-basin.

The present research addressed the problem of pesticide management and deficient use by applying a questionnaire to a sample of small farmers on the central coast of Peru, this problem is repetitive and worrisome in different Latin American countries that do not have adequate regulation of its agricultural production for domestic market. The results indicated the use of unauthorized pesticides, due to the lack of recommended registered products, as well as non-compliance in the recommended dose. Additionally, the rotation of active ingredients per mode of action is limited and the terms of lack are not respected, aggravating in the case of products destined for the national market. Likewise, the recommendations of the re-entry periods and the use of personal protective equipment are not complied with.

The interconnection of computing devices, sensors, people, things and animals, is the internet of things (Iot) and its growth is exponential since every day there are more of these connected to the network. Its influence in the society is such that it has generated great changes in all the areas like: medicine, education, economy, industry, security, services of all type and in agriculture; the latter has been transformed with the use of intelligent agricultural machines, intelligent pest control, drones to monitor crops and livestock, use of stations that capture agro-chemical variables that have made possible the collection and use of large amounts of critical data with minimum costs, which has achieved an agricultural process more information-oriented and potentially more productive and efficient. This research aims to make a bibliographic review of how the internet of things is closely linked to precision agriculture, for this a documentary research was applied investigating diverse sources such as indexed magazines, books, official and government pages. As a result, it was determined that there is a marriage that is currently inherent between the internet at all and precision agriculture and provides the basis to devise sustainable projects based on Iot for the development of the Province of Los Ríos, which is agricultural par excellence.

This research was carried out at the Technical University of Babahoyo, Agricultural Sciences Faculty, located at 7 ½ Km from the Babahoyo-Montalvo road. The main objectives of the study are: To evaluate the chemical fertilization effect, based on the rice crops’ soil analysis, to identify the highest production genotype, and to analyze the chemical fertilization treatments from the economic point of view. Three treatments (genetic material), such as INIAP 15, GO37647, and GO39845 lines were used, as well as four sub-treatments (fertilization levels) with four repetitions, based on nitrogen (urea), potassium (muriate of potassium) and Zinc (Zinquell). The divided plot design, with three treatments, four sub-treatments, and four repetitions was used. The Duncan's Multiple Range Test, at 5 % probability, was utilized for the comparison of variables’ averages. Based on the results obtained in this study, it can be concluded that for plant height, panicle length, flowering, and crop maturation, high statistical significance was obtained for genetic material; the number of stalks per m2, and grains per panicle had a 95% significance, both for genetic material and for fertilization; while the control with no fertilization reached only 2.47 ton /ha. The soil was mainly lacking in nitrogen, and to a lesser extent in K and Zn. In terms of grain quality, the GO39845 with peeled rice surpassed the line by 68%, and the soil chemical analysis was a good tool for crop fertilization.  

The research work contributed to the improvement of teaching methods and techniques, the learning of experimental sciences, the basis for the use of ICT and the mechanisms of acquisition of meaningful learning and thus strengthen the didactic processes used by teachers of Baccalaureate. The importance lies mainly in the development of students' experimental and technological abilities and skills for the effective linkage of tools of this type in the acquisition of knowledge. Methods such as bibliography were used; which allow it to be known that the subject to which the results obtained to depart from this have been said, establish our starting point; In addition, methods such as inductive and deductive methods were used; as well as the experimental and hermeneutic methods that, in a special way, allowed us to carry out fieldwork to establish the conclusions and thus measure the impact that ICTs have in this broad field of education. Among the results obtained, it is evident that 77% of the cases in which technical tools were used in their experimental processes with their students, who achieved the most dynamic training in relation to the classes given to the teachers that were not used; Regarding learning, it was evident that 95% of students generated significant learning from constructivism. This research allows the use of ICT in educational processes to be incorporated with greater commitment.

In this article, an explanation is presented in the improvement of the learning of derivatives and integrals making use of this computer program, GeoGebra, in university students, in order to be implemented in higher education in the area of ​​mathematics in the school of systems engineer. Since one of the problems that we face in local and national situation is the insufficient benefit in higher mathematics in students. This problematic the probable causality is the restriction of the use of didactic resources, the exorbitant use of the blackboard, limited bibliographic resources to capacity, a traditional methodology where the students are a passive entity and receptive of the themes, the non insertion of the novelties Technological changes in the classroom are one of the possible reasons that would produce the diminutive performance of mathematics in students. That is why the GeoGebra program is important, which facilitates learning, thus solving more exercises and with great motivation they learn the differential and integral calculus. This work has application in derivative and integral subjects, the same ones that are improved year after year and evidence the transcendence of such application. The study was framed within the quantitative approach, deductive hypothetical method, applied type, experimental-quasi-experimental design, evaluation technique, and the sample selected to carry out this research was made up of 60 students in each group of the second cycle of the Systems engineer. The GeoGebra software improves the learning of differential and integral calculus.

Sciences as they would define their object of study became independent of philosophy, which served as their mother. Therefore, history, philosophy, theology, psychology, technology, research, among others, now appear from a disciplinary perspective. This work reflects on the Philosophy of technology, from social relevance, which begins with an analysis of the categories of traditional philosophy: ontology, epistemology, teleology and axiology, then it requires relevant facts and events that have been decisive for the establishment of stages in the history of science in general. The historical stages of philosophy, literature and other sciences are the ancient, pre-modern, modern and postmodern. The messages issued within the communication process developed by the human being, constitutes another of the axes to establish stages such as oral, scriptural and electronic, which are particularized in analog and digital, to strengthen the philosophical foundation of each of these stages. The research, despite its chronological journey, from ancient times to these days, responds to a diachronic approach and transcends the transdisciplinary; moreover, when facts or events are required, that appears at one stage, constitutes the relevant of the next, or the opposite, that belonging to this stage, was antecedent of the immediate previous. It concludes with a contribution to scientific theory with the conceptualization of technology with social relevance, since it is, philosophically based on its use for the benefit of society and the individual, as well as being a transcendent axis in contributing to the requirements, context needs and problems. Technology philosophy is the hope to reduce the gaps generated between nations and individuals and technology itself.

This article explores the corporal memories of a group of indigenous women ex-combatants of the FARC settled in the Colombian Caribbean, under analyze in the specialize literature. Using the methodological approach of participatory-action research, the critical pedagogy, and the communitarian feminism, techniques such as social cartographies, autobiographical workshops, memory albums, doll making and ethnographic observations, were implemented, to make these memories as a place of representation and identity construction. The corporeal memories of this group of indigenous women, showed the emergence of new identities in production and recreation, between the tensions of corporal discipline and individual autonomy conveyed by indigenous traditional dresses, the FARC’s uniform and the «trousseau of the princesses».

Peace Studies have taken special interest in international ambit, due to indiscriminate violence escalation in every form, which affects everybody no matter what gender, age, race, religion or socioeconomic conditions. With this scenario, the alternative is building a culture of peace. In the education sphere, all the universities are agencies that should play an active role in this process. This work presents an investigations revision about peace culture in the university environment in Colombia published in the last decade, particularly those which the main target is identifying the social representatives of university students in relation with the peace culture and how to build it, as well as what is the role that the university plays in the peace process. This becomes a contribution to the field of peace studies and for students and academics interested in this field of study. In order to achieve this, we analyzed those document releases, from both quality and quantity point of view by setting four ranks: methodology and technics, theory references, project origin, subjects of studies and findings. The result of the analysis focused on how students distinguish the university and the peace as interacting elements.

The objective of this work is to analyze the values and the attitude in which the students of the Master in Studies for Peace and Development of the Faculty of Political and Social Sciences of the UAEMéx face the conflicts in the classroom, either through evasion, accommodation (complacency), competition, negotiation or cooperation. The model used by Paco Cascón (2001), through which new ways of making peace are envisioned, as we consider it important to learn to manage conflicts in a positive, creative and peaceful way.Quantitative and documentary research were used to define the values, attitudes and styles of dealing with conflict through measurement indicators. In order to obtain the information in the field, three different types of Lickert-type measurement scales were applied in order to know which values are more entrenched by teachers, as well as the attitude and style of resolving their conflicts in the classroom.The most significant results was knowing if they knew how to dialogue and we concluded the need to make efforts to be dialogic. Regarding the values, the students responded that honesty was the most important and in the results of the questions, they argued that it was justice and the least important was creativity. In the five styles of dealing with conflict, the most used is negotiation, leaving the complacent style at the end.
