Authors: Calderón Luz Elena Alfonsina Ávila , Sotomayor Castellanos Javier Ramón
Published: July 2024

Introducción: La madera es un material biodegradable y su empleo requiere información sobre el efecto de substancias protectoras en sus propiedades mecánicas. De tal forma que es importante desarrollar tecnología para su conservación cuando está en servicio.
Objetivo: Impregnar con sales de boro, empleando el método de baño caliente-frío, probetas normalizadas de Fraxinus americana, Albizia plurijuga y Spathodea campanulata.
Metodología: Se determinó la retención de sales de boro, densidad, velocidad de onda y módulo dinámico de la madera. Se realizaron pruebas de ondas de esfuerzo antes y después del tratamiento de impregnación.del estudio.
Resultados: La retención aumenta a medida que la concentración se incrementa y disminuye a medida que la densidad de la madera aumenta. No se observaron diferencias estadísticamente significativas entre las muestras de las densidades y las velocidades de onda de cada especie. Para los módulos de elasticidad de S. campanulata no se encontraron diferencias. Para F. americana y A. plurijuga sí se identificaron diferencias.
Conclusiones: Los resultados sugieren que la capacidad de retención de sales de boro de la madera depende, principalmente, de la especie. Los valores promedio de la retención de sales de boro para las concentraciones de 3% fueron mayores que el límite inferior tóxico de retención para satisfacer los requerimientos mínimos de las normas para madera utilizada en espacios interiores. Para fines de diseño y cálculo ingenieril, es recomendable considerar el alcance de los resultados de esta investigación que se limita a probetas de pequeñas dimensiones.

Authors: Piñeros Rodríguez Camilo Andrés , Sierra Martinez Luz Marina , Peluffo Ordoñez Diego Hernán , Timana Peña Jimena Adriana
Published: July 2024

Introduction − Making effort estimation as accurate and suitable for software development projects becomes a fundamental stage to favor its success, which is a difficult task, since the application of these techniques in constant changing agile development projects raises the need to evaluate different methods frequently. 
Objectives− The objective of this study is to provide a state of the art on techniques of effort estimation in agile software development (ASD), performance evaluation and the drawbacks that arise in its application. 
Method− A systematic mapping was developed involving the creation of research questions to provide a layout of this study, analysis of related words for the implementation of a search query to obtain related studies, application of exclusion, inclusion, and quality criteria to filter nonrelated studies and finally the organization and extraction of the necessary information from each study.  
Results− 25 studies were selected; the main findings are: the most applied estimation techniques in agile contexts are: Estimation of Story Points (SP) followed by Planning Poker (PP) and Expert Judgment (EJ). The most frequent solutions supported in computational techniques such as: Naive Bayes, Regression Algorithms and Hybrid System; also, the performance evaluation measures Mean Magnitude of Relative Error (MMRE), Prediction Assessment (PRED) and Mean Absolute Error (MAE) have been found to be the most commonly used. Additionally, parameters such as feasibility, experience, and the delivery of expert knowledge, as well as the constant particularity and lack of data in the process of creating models to be applied to a limited number of environments are the challenges that arise the most when estimating software in agile software development (ASD)   
Conclusions− It has been found there is an increase in the number of articles that address effort estimation in agile development, however, it becomes evident the need to improve the accuracy of the estimation by using estimation  techniques supported in machine learning  that have been shown to facilitate and improve the performance of this.

Authors: Narváez Figueroa Andrés Eduardo , Cáceres Castellanos Gustavo , González Sanabria Juan Sebastián
Published: July 2024

Introduction— The United Nations Office on Drugs and Crime (UNODC) classifies Colombia as one of the countries where drug trafficking and crime threaten the security, peace and development opportunities of its citizens.
Objective— This article presents the application of the unsupervised K-means classification algorithm to categorize municipalities with coca cultivation presence in Colombia. Methodology- The CRISP-DM methodology was used for data mining, and the PCA (Principal Component Analysis) algorithm was used for the correlation of variables.
Results— Multiple sources of information were used, such as: the number of hectares of coca per municipality, seizures, laboratories destroyed, manual eradication and fumigation, monitored by national institutions, in order to make crosses with socioeconomic and performance variables of the municipalities with coca crops in the period from 2010 to 2020. Based on the classification, the scenarios of each category were analyzed to find scenarios that allow elucidating the dynamics of the territories suffering from this scourge.
Conclusions— It was found that the behavior of coca-producing municipalities responds mainly to 4 groups. It was also found that the municipality of Tumaco in Nariño does not fit into any category since it exceeds the production with respect to the other municipalities.

Authors: De Moya Sánchez Angel , Casierra-Martínez Henry Alberto , Vargas-Ramírez Ximena , Caselles-Osorio Aracelly
Published: July 2024

Introduction: Constructed wetlands (CWs) are a recognized technology to treat industrial wastewater.
Objective: A pilot system of two horizontal subsurface flow CWs was used to remove Cr and Zn from industrial synthetic wastewater.
Method: The study was carried out at Universidad del Atlántico in Barranquilla, Colombia. Two containers of 0.375 m2 were filled with a gravel bed (~10 mm and 40% of porosity) and a 0.3 m water column. One container was planted with Cyperus odoratus L. and another without plants was used as a control.
Results:  The removal efficiency of Cr and Zn was 93% and 96% in the CW planted, respectively and 67% and 98% removal were obtained in the unplanted system with statistical differences (P<0,05). The observed difference in biomass production (0.1 and 0.6 kg/m2) could be related to seasonal weather that could have favored the growth of the plant.  C. odoratus reached a Translocation Factor greater than 1.5 for Cr and Zn, which is greater than that, reported by others for Cyperus species. However, a Bioconcentration Factor > 13.6 for Zn and < 7.7 for Cr indicated that C. odoratus is an accumulator species for Cr and Zn. Sorption metal processes in gravel can be occurring due to the high removal efficiency of Zn in unplanted systems
Conclusions:  These results show that C. odoratus could be recommended for use in constructed wetlands technology due to fast-growing and absorption and translocation heavy metals capacity.

Authors: González García Alexander ,   Universidad Libre
Published: July 2024

RÉSUMÉ: Cette étude décrit dans quelle mesure l’accompagnement des éducateurs d’un collège jésuite vise la formation intégrale de l’élève pour répondre aux valeurs ignatiennes, notamment le service des autres. Cette recherche développe quatre dimensions de l’accompagnement intégral : intellectuelle, affective, sociale et spirituelle. L’étude adopte la méthode quantitative, en cohérence avec le paradigme positiviste. Une enquête par questionnaire est lancée auprès de 316 élèves des cycles complémentaire et secondaire pour mesurer l’intégralité de sa formation. À la fin, l’étude montre l’existence d’un accompagnement intégral au Collège à plusieurs niveaux. Toutefois, à la lumière des résultats, certains aspects gagneraient à être davantage développés tels que « le service des autres », « la résolution pacifiste des conflits » et « une meilleure qualité dans la participation à la communauté de foi ». À titre indicatif, cette recherche a débouché sur l’élaboration d’un dispositif d’accompagnement des éducateurs selon la pédagogie ignatienne. ABSTRACT: This study describes to what extent the educator’s support at a Jesuit school aims at the integral formation of students to meet Ignatian values, mostly the service of others. The research develops four dimensions of the integral accompaniment of the students: intellectual, affective, social and spiritual. To accomplish our objective, we adopt the quantitative approach consistent with the positive paradigm. With a questionnaire we surveyed responses from 316 students of a secondary school to measure the effects of the integral formation of students. At the end, the study reveals the presence of integral support in the school at several levels. However, the results indicate that some of its aspects do still need further development such as « service to others », « pacifist conflict resolution » and « better quality in participation in the faith community ». Finally, we are proposing in this research a system of support for the educator so as to improve their accompaniment of the students within the framework of the Ignatian Pedagogy.

Authors: Tapia Larios Claudia ,   Universidad Libre
Published: July 2024

La pesca es una actividad importante para muchas comunidades en Colombia, principalmente en el Caribe, en donde contribuye al sostenimiento de muchas familias. La obtención de productos como el pescado, el marisco, entre otros, es muy relevante. Sin embargo, este documento se enfoca en el pescado, por ser el producto más consumido y, a su vez, el que tiene más riesgo de infección. Son muchos los municipios del Atlántico que viven de la pesca, por lo cual es necesario conocer ciertas características del agua y de los microorganismos que la habitan, que afectan directamente la calidad de este producto. Dada esta necesidad, la Universidad Libre, a través del programa de Microbiología y el grupo de Gestión Ecológica y Agroindustrial (GEA), junto con la Universidad del Atlántico y su Licenciatura en Biología y Química, y el grupo de investigación en Biotecnología de Microalgas, Fisicoquímica Aplicada y Estudios Ambientales, de la Facultad de Ciencias Básicas, y la participación de la Autoridad Nacional de Acuicultura y Pesca (AUNAP) crearon esta cartilla pedagógica para capacitar a la comunidad de pescadores y pequeños acuicultores en el cuidado del agua y buenas prácticas en el manejo de los recursos pesqueros. En esta cartilla aparecen conceptos que permiten identificar la importancia de las cianobacterias y la forma como afectan a los organismos que interactúan con ellas. Adicionalmente, se plantean diversas actividades didácticas que mejorarán la comprensión de la información impartida.
Local Banking Supply and Private Firm Activity: Evidence from Branch Closures
Authors: Fang Francis , Vlaicu Razvan
Published: July 2024

Private firms establish relationships with banks in local markets to obtain adequate financing for their operations through credit and loans. As major banks reduced their branch networks in recent years, many firms have lost access to their local bank. We evaluate the impact of a large number of branch closures on firm operations, wages and employment, and economic output in Brazil from 2011 to 2021. We adopt a difference-in-differences strategy with staggered treatment timing, employing both two-way fixed effects and Callaway-Sant'Anna estimators. Our study finds that bank branch closures result in a reduction in establishments with active operations from 1.2% initially to 8.1% within 4-7 years, a 0.5 decline in weekly hours of formal employment, and a compression in the real wage distribution. Micro firms, trade and service firms, and agricultural firms are found to be the most vulnerable. Our study highlights the importance of physical bank branches that provide financial access and meet the localized financial demand of several types of firms.

AIM: To describe the surgical procedure of fusiform penetrating keratoplasty (FPK) using multiple trephines of different sizes for treating patients with severe infectious keratitis.
METHODS: Fourteen eyes underwent FPK, and 15 eyes received conventional penetrating keratoplasty (PK) were included in the study. The best-corrected visual acuity (BCVA), refractive outcomes, endothelial cell density, and postoperative complications were recorded.
RESULTS: The FPK group was followed for an average of 15.3±2.1mo, whereas the PK group was followed for 16.1±1.9mo. The corneal ulcers were elliptical-shaped in all 14 eyes in the FPK group. The mean BCVA (logMAR, 0.26±0.13) showed no statistically significant differences from that in the PK group (logMAR, 0.21±0.12, P>0.05) at 1y after surgery. But the mean curvature, mean astigmatism, and mean spherical equivalent in the FPK group were lower than those in the PK group (P<0.05). Peripheral anterior synechia was observed in one patient in the FPK group, whereas 6 patients in the PK group. Suture loosening and neovascularization were observed in 4 and 5 eyes in the PK group, respectively. No graft immune rejection or elevation of intraocular pressure was observed in the two groups.
CONCLUSION: For patients with elliptical-shaped corneas or corneal ulcers, FPK can avoid disrupting of corneal limbus, reduce the risk of postoperative complications, and can result in satisfactory visual quality.

AIM: To determine whether the levator palpebrae superioris (LPS)/superior rectus (SR) muscle complex, can influence the position of the upper lid and fornix in acquired anophthalmic sockets.
METHODS: This comparative non-randomized and non-interventional study included retrospective data of 21 patients with unilateral acquired anophthalmic sockets repaired with spheric implants. High-resolution computed tomography (CT) measurements of the LPM/SR muscle complex and clinical topographic position of the upper lid, superior and inferior fornix depth in primary gaze position were evaluated. Demographic data were presented as frequency and percentage proportions and quantitative variables comparing the socket measurements with the normal contralateral orbit was statistically analyzed using non-parametric tests considering P<0.05.
RESULTS: The anophthalmic orbits had a significantly shorter LPS length (P=0.01) and significantly thicker SR (P=0.02) than the normal orbit. Lagophthalmos was present in anophthalmic sockets but not in normal orbits (P=0.002), while levator function was normal in both (P>0.05, all comparisons). The superior fornix depth was similar in the anophthalmic socket and the contralateral normal orbit (P=0.192) as well the inferior fornix depth (P=0.351).
CONCLUSION: Acquired anophthalmic sockets repaired with spheric implants have shorter LPS, thicker SR, and more lagophthalmos than normal orbits. The relationship of the LPS and SR with other orbital structures, associated with passive or active forces acting in the final position of the lids and external ocular prosthesis should be further investigated.

Owing to the rapid development of modern computer technologies, artificial intelligence (AI) has emerged as an essential instrument for intelligent analysis across a range of fields. AI has been proven to be highly effective in ophthalmology, where it is frequently used for identifying, diagnosing, and typing retinal diseases. An increasing number of researchers have begun to comprehensively map patients’ retinal diseases using AI, which has made individualized clinical prediction and treatment possible. These include prognostic improvement, risk prediction, progression assessment, and interventional therapies for retinal diseases. Researchers have used a range of input data methods to increase the accuracy and dependability of the results, including the use of tabular, textual, or image-based input data. They also combined the analyses of multiple types of input data. To give ophthalmologists access to precise, individualized, and high-quality treatment strategies that will further optimize treatment outcomes, this review summarizes the latest findings in AI research related to the prediction and guidance of clinical diagnosis and treatment of retinal diseases.

Published: July 2024

Tanzania's land laws protect and guarantees gender equality in access, ownership, and utilization of land. However, the extent to which these legal frameworks have enabled gender equality in the country regarding access, ownership, and utilization of land is not well known. This paper assessed gender relations in access, ownership, and utilization of land in West Usambara Mountains Lushoto District, Tanga Region, North Eastern Tanzania. A purposive sampling of 100 respondents (49 men and 51 women) was obtained to participate in the study. A structured questionnaire was used to interview respondents and focus group discussions with key informants were conducted. Qualitative data were analyzed through content analysis techniques including thematic analysis of texts and indexing. Results show that despite a progressive legal framework, women are still marginalized in land access, ownership, and utilization. This is because of the co-existence of dissimilar structures (traditional, formal and religious land laws), as well as long-established traditional that continue to perpetuate gender disparity. It is proposed that efforts should be made to empower women to use the existing legal structures to demand and promote own land rights.

Published: July 2024

This is the qualitative descriptive agenda-building phenomenon study of the National Awakening Party campaigns widely known as Partai Kebangkitan Bangsa, PKB, in Tulungagung during the 2024 election. It describes and explains phenomena without manipulating variables or interventions, providing depth of understanding of context, characteristics, and dynamics of events. The success of PKB's agenda setting in Tulungagung was corroborated by the party itself, which won 9 seats in the regional parliamentary body compared to 7 in 2019. More success was accounted for with regard to the comprehensiveness of the process: from internal operations that had closed and later opened meetings, sessions consolidating PKB visions and missions, down to aligning candidate training. Afterwards, it was followed by a string of thematically based events, which took up matters such as agricultural policy, effective political participation of youth, and promotion of small businesses. These activities mobilized different sets of voters and culminated with the grand finale of this campaign. Such multi-dimensional effort outperformed the electioneering goals set by the party, and efficiency of the party's agenda-building operations was more than well attested. The present paper enlightens on how to mount a political campaign and reinforces tailored and inclusive agenda building. Hence, these results provide real practical implications for the political communication and campaigning strategies to enable success at the polls.
