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.</span></p> Maikol Rivas Eladio Lobo Copyright (c) 2023 Maikol Rivas, Eladio Lobo https://creativecommons.org/licenses/by/4.0/deed.es 2023-12-01 2023-12-01 4 12 9 20 10.47460/minerva.v4i12.132 Application of the SBAR-SAER technique by the nursing professional https://minerva.autanabooks.com/index.php/Minerva/article/view/133 <p><span class="OYPEnA text-decoration-none text-strikethrough-none">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.</span> <span class="OYPEnA text-decoration-none text-strikethrough-none">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.</span></p> Maria Elizabeth Chacha Benitez Eulalia Isabel Analuisa Jimenez Copyright (c) 2023 Maria Elizabeth Chacha Benitez, Eulalia Isabel Analuisa Jimenez https://creativecommons.org/licenses/by/4.0/deed.es 2023-12-01 2023-12-01 4 12 21 28 10.47460/minerva.v4i12.133 Obtaining glycerol from the transesterification of used edible oils https://minerva.autanabooks.com/index.php/Minerva/article/view/134 <p><span class="OYPEnA text-decoration-none text-strikethrough-none">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.</span></p> Steeven Jose Analuisa Mero Luis Alberto Moreno Ponce Segundo Alcides Garcia Muentes Ramon Eudoro Cevallos Cedeno Ariana Milena Garcia Bowen Copyright (c) 2023 Steeven Jose Analuisa Mero, Luis Alberto Moreno Ponce, Segundo Alcides Garcia Muentes, Ramon Eudoro Cevallos Cedeno, Ariana Milena Garcia Bowen https://creativecommons.org/licenses/by/4.0/deed.es 2023-12-01 2023-12-01 4 12 29 38 10.47460/minerva.v4i12.134 Impact of innovations in object-oriented programming on the creation of new design patterns https://minerva.autanabooks.com/index.php/Minerva/article/view/135 <p><span class="OYPEnA text-decoration-none text-strikethrough-none">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.</span></p> Jose Belisario Vera Vera Julio Agustin Molina Zambrano Yimmy Salvador Loor Vera Jose Rafael Vera Vera Copyright (c) 2023 Jose Belisario Vera Vera, Julio Agustin Molina Zambrano, Yimmy Salvador Loor Vera, Jose Rafael Vera Vera https://creativecommons.org/licenses/by/4.0/deed.es 2023-12-01 2023-12-01 4 12 39 47 10.47460/minerva.v4i12.135
