This paper analyzed the effectiveness of interactive applications as a didactic strategy in developing mathematical skills in primary school students. This is an explanatory, exploratory, quasi-experimental, and longitudinal study. We worked with a control group and an experimental group. The population consisted of 38 primary school students. The main results show that interactive technological applications are effective as a didactic strategy in developing mathematical skills, achieving a significant difference in the tests applied to the control group in correspondence with the experimental group. These findings reveal that teaching mathematics must be innovative without neglecting the classical elements that make meaningful learning possible.

This research aims to conduct a socioeconomic study of the cocoa production chain in the province of Esmeraldas through a descriptive analysis from 2016 to 2021, using primary sources from the Agricultural Public Information System (SIPA) database. According to the type of study, it was carried out in a cross-sectional manner since the data of variables obtained in a specific period of time were analyzed to establish fundamental particularities such as: standard deviation, kurtosis, and ranges. To determine the price and production of cocoa, it was developed through histograms, time series, and correlations to obtain detailed data and thus know the link between the variables under study.

The present work aims to take advantage of residues from plantain and banana for the elaboration of flours that comply with the norms NTC-2799:1991 and NTE-INEN-616:2006. The experimental work involved preparing plantain and banana peels and then taking them to grinding and sifting. The results show good quality flour that meets the rigors of the Colombian Technical Standards. However, E. coli bacteria were observed in the developed flours, which should be considered to improve hygiene in the production process.

In this descriptive study, the degree of satisfaction of students in community engagement activities was investigated using the experience of learning through service. The sample consisted of 30 students, and content analysis and descriptive data study were used as the main analysis techniques. The outstanding results revealed that bonding activities allow students to acquire skills and abilities for incorporation into social environments. It was also observed that there is a high degree of satisfaction with the processes carried out and the competencies acquired, and the relationship of the concepts with the practical experiences shows less satisfaction in the procedures carried out. These results reveal the rewarding experience, but some aspects can still be improved.

This research evaluated the effectiveness of integrating home experiments as a didactic strategy in the Natural Sciences curriculum aimed at primary school students. The study took a mixed approach and was conducted using a sample of 24 students randomly assigned to two groups of 12 each. One of these groups received conventional instruction, while the other was introduced to four home experiments in two units. Pre- and post-test tests were implemented as a measurement strategy to evaluate the incidence of home experiments. The experimental design was a Completely Randomized Design (DCA) with twelve replications. The results obtained indicated that the inclusion of home experiments had a positive impact on the learning process. In addition, they facilitated the connection between theoretical concepts and situations in everyday life.

The present study analyzed the application of the SBAR-SAER technique by nursing professionals. This was a quantitative, descriptive, and cross-sectional investigation with a non-probabilistic sample. They were applied to 154 nursing professionals from a hospital in Ambato, Ecuador. The main results show that most nursing professionals know this method for transferring information between professionals in charge of the continuity of patient care. In addition, several factors were identified for using this tool, such as patient safety, effectiveness, and ease of communication. Finally, there is a high rate of SBAR-SAER application among the hospital's nursing professionals.

This research focuses on delving into the impact of innovations in object-oriented programming on creating new design patterns. This paper presents possible innovations in object-oriented programming and its impact on design patterns for software development. The developers of these systems face the challenge of designing not a single system but several ways to solve the same problem and introduce innovations that allow them to modify and extend the codes quickly and easily. To illustrate how a design pattern is applied in an object-oriented system, an order management system for an online vehicle parts sale is shown. For this case, the Factory Method design pattern is selected to handle creating product objects (spare parts) dynamically and efficiently, which is a first step in building large systems.

This paper presents a study on obtaining glycerol as a by-product of the transesterification of edible oils used to prepare hydrogel. The main results show that obtaining pure and refined glycerol is possible. In addition, it was observed that the parameters were within the regulations presented by several authors. It was also observed that the glycerol with better properties was obtained at 60 minutes at a temperature of 60 °C. In this way, it is possible to affirm that it is viable to use discarded oils as an alternative for their application in the elaboration of products that benefit the chemical, cosmetic, and pharmaceutical industries, as is the case of hydrogel, thus avoiding their incorporation into the environment.

In inventories, the context of object counting and speed of response becomes essential. The process is more straightforward when there are only a few items, but its complexity lies when there are many close or overlapping items. In addition, the pressure to meet tight inventory deadlines adds another challenge. This work aimed to develop a program that automates the accurate counting of similar objects in digital images, regardless of their quantity or arrangement. For this purpose, an algorithm has been implemented in Python. The main results show efficiency in analyzing images with similar objects, a significant step towards separating and accurately counting adjacent objects in various scientific fields. This solution promises to simplify and speed up the counting process in digital images, with potential beneficial applications in multiple scientific disciplines.

Abstract A critical debate has blossomed within the field of research policy, science and technology studies, and philosophy of science regarding the possible benefits and limitations of allocating extramural grants using a lottery system. The most common view among those supporting the lottery idea is that some form of modified lottery is acceptable, if properly combined with peer review. This means that partial randomization can be applied only after experts have screened the pursuit-worthiness of all submitted proposals and sorted out those of lowest quality. In the present paper, I will argue against the use of partial lotteries or partial randomization and instead promote use of a pure lottery in combination with a radical increase in block funding. The main reason for holding this position is that a partial lottery cannot solve the problems inherent in the current funding system, which is based on grant competitions and peer review. A partial lottery cannot decrease the enormous time-waste, reduce the uneven distribution of time between researchers, neutralize expert biases or mitigate academic power asymmetries. Instead, we need a stronger focus on improving general time management in academia by implementing a more holistic model for organizing research opportunities in the future.
