Item Acceso ciudadano en la justicia como ejercicio dinámico de publicidad y contradicción, mediante estrategias garantes del debido proceso (acceso digital de pruebas)(Corporación Universitaria Lasallista, 2015-09-07) Meza Ortiz, Hernando; Silvera Sarmiento, Astelio; Pineda Carreño, Mariangélica; Páez, José Miguel; Pérez Vanegas, Lenin EstebanAmong the problems that come up from the participation of citizens and that affect justice as a base of the principles of advertising, contradiction and due process, social strategies that allow the integral development of citizenship and democracy are gathered. These, along with the strengthening of citizenship competencies, make interdisciplinarity and social transformation practices feasible for an interdisciplinary dynamic exercise. Determine the efficiency of the means citizens have to access to justice, in the different notification ways, as a dynamic exercise of advertising and contradiction, by means of strategies that guarantee due process in terms of electronic devices. Materials and methods. To develop this topic the analytic-descriptive method I used, with a dialogical and interdisciplinary focus. This is due to the fact that the study of the issue integrates the dynamic social practice and the applied research to the law, by means of the analysis of contents and the description of the jurisprudential line taken as a base for the structure made to have a constitutional comprehension of the hermeneutical turns the jurisprudence and the doctrine on the subject have. There is a necessity to establish interdisciplinary spaces for the development of citizenship supported by a real action of the citizens and of the mechanisms that guarantee participation in democracy and representation contexts, under the mediation of technological and ICT scenarios.Item Acceso y uso de la web 2.0 en los ambientes educativos étnicos de Riohacha-La Guajira(Corporación Universitaria Lasallista, 2017) Pitre Redondo, Remedios; Moscote Almanza, Hilder; Curiel Gómez, Rebeca; Archila Guio, Jesús Enrique; Amaya López, NicolásIntroduction.

Its importance has strengthened and its validity is larger every day. Therefore, to inquire about its impact is a topic of interest for all agents of academic environments. Objectives. The purpose of this article is to evaluate if teachers have access to WEB 2.0 and how have they been using this essential tool in ethno-educative centers of Riohacha city. Materials and Methods. The type of research performed was the descriptive kind, with a non-experimental/transactional approach. From a population of 64 teachers in the ethno-education centers, a sample of 45 teachers was taken; they should participate in the application of the instrument under the Likert scale, which object was to identify its interaction level with applications and other web 2.0 features. The results were analyzed in Excel software, which generated supporting information to reflection. Results. The findings allow assuring that a large amount of the teachers has access and put in practice the tools in their daily duties. Conclusions. After analyzing the different stages of the research, it can be concluded that the teacher, at present, has access and put into use the Web 2.0 tools; likewise, they maintain a special orientation to be trained and carry on the academic management supported in several applications.Item Aceite de Clavo (Eugenol®) como Anestésico en la Especie Panaque Cochliodon-Steindachner, 1879 (Cucha de Ojos Azules).(Unilasallista Corporación Universitaria, Editorial Lasallista, 2022) David Ruales, Carlos Arturo; Guerra Jiménez, Manuel Oswaldo; Cano Gil, Juan David; Betancur González, Eliana MarcelaLa cucha de ojos azules (Panaque cochliodon) es una especie endémica de la cuenca del Cauca y el Magdalena. Sin embargo, no se tiene mucha información sobre esta especie, incluida la ausencia de un protocolo de sedación adecuado para el trabajo en cautiverio con esta especie. Objetivo: estandarizar un protocolo de sedación del P. cochliodon. Materiales y métodos: se evaluaron diferentes concentraciones del sedante Eugenol que iban desde 20 a 40 mg/L; se adoptaron 4 tipos de sedación y 5 tipos de recuperación, encontrando así los grados de sedación adecuados para los diferentes procedimientos de manejo en confinamiento que se realizaron con esta especie. Resultados: todos los ejemplares alcanzaron la sedación tipo 4 y la recuperación tipo 5 sin mortalidad. Significativamente la concentración a la cual los ejemplares demoraron más tiempo en alcanzar la sedación tipo 4 y recuperación tipo 5 fue la de 20 mg/L, las demás concentraciones no presentaron diferencias entre sí, pero indican una tendencia inversa con respecto a la concentración y el tiempo. Conclusiones: todas las concentraciones evaluadas son seguras para el manejo de P. cochliodon de 314±11,6 gr, no se presentó mortalidad; las concentraciones de 30 a 35 mg/L, ofrecen 2,6 minutos de trabajo, sin efectos deletéreos aparentes sobre la especie.Item Acople fotocatalítico - biológico para el tratamiento de desechos complejométricos generados en laboratorios de análisis químico y ambiental(Corporación Universitaria Lasallista, 2010) Baquero Dulcey, Martha Isabel; Sterling López, Adriana María; Mera Benavides, Adriana ConsueloIntroducción. La fotocatálisis heterogénea es útil como pretratamiento antes de un tratamiento biológico para contaminantes resistentes a la biodegradación. La fitorremediación se utiliza para degradar y extraer contaminantes del ambiente. El acople de estas dos técnicas podría ser una buena alternativa para el tratamiento de desechos complejométricos con presencia de indicadores metalocrómicos. Objetivo. Aplicar fotocatálisis y fitorremediación a desechos complejométricos generados en el laboratorio de Ingeniería Ambiental y Sanitaria de la Universidad del Cauca. Materiales y métodos. Para el proceso de fotocatálisis se utilizó un foto-reactor y se analizaron las condiciones bajo las cuales se obtuvieron los mayores porcentajes de degradación y mineralización del indicador Negro de Ericromo T (NET). En el proceso de fitorremediación se utilizaron reactores con plantas acuáticas y el control se realizó por medio del conteo de frondas y análisis químico. Resultados. Las condiciones óptimas para el tratamiento del desecho con presencia del indicador complejométrico NET son: 0,3 g/L de catalizador TiO2, 80 ppm de H2O2 y un tiempo de exposición de luz UV de tres horas, obteniéndose un porcentaje de degradación del NET de 86,85%. En el proceso de fitorremediación no se alcanzó la remoción de sales esperada para este experimento. Conclusión. La utilización de concentraciones adecuadas de TiO2 y H2O2 permite obtener buenos porcentajes de degradación del indicador NET presente en desechos químicos. Se recomienda realizar un estudio más detallado que permita la elección de otro tipo de tratamiento biológico complementario al fotocatalítico, que logre la remoción de las sales presentes.Item Acreditaciones internacionales en escuelas de negocios. Una revisión de la literatura(Corporación Universitaria Lasallista, 2017) Lombana Coy, Jahir; Zapata, ÁlvaroIntroduction. International accreditations have become a means to reflect the characteristics of business schools to their stakeholders. However, there is still a debate about its validity as a quality model, the different standards between accreditors and the perception towards them. That is why more detailed exploration is required, especially from developing countries. Objective. Review and identify the matching elements in the academic literature regarding international accreditations, with emphasis on AACSB and EQUIS. Materials and methods. Through a narrative methodology of literature review, 3025 articles were disaggregated from 21 databases and identifying as fundamental authors Urgel (2007), Hunt (2015), Lejeune (2011) and Shenton (2010), as well as information on the Accreditations AACSB and EQUIS. Results. Repetitive elements are presented in the literature: 1) the dichotomy between accreditation as a means to obtain reputation or improve educational quality; 2) accreditation agencies and their standards, and 3) perceptions of the result of being accredited. Conclusions. The debate about quality or reputation in Business Schools continues; the emphasis of the accreditation bodies is on internationalization, academic development and research; and positive results of accrediting, according to the interest groups, are still inconclusive. Research topics are opened in the areas of emphasis of the accreditation and in the context that should be done for developing countries where research is still incipient.Item Adaptive User Profiling Scheme Using Brain Imaging(Corporación Universitaria Lasallista, Editorial Lasallista, 2013) Gaviria Giraldo, Julián; Jiménez Builes, Jovani AlbertoThis article shows how computer science and cognitive neuroscience can be merged to propose an effective profiling scheme. In the area of user profiling this paper will provide the paths and trends that researches has already gone through, and how some issues are being overpassed. In other words, this work will solve effectively one issue: con-tent personalization through the identification of an individual’s learning behavior. objective. This work will demonstrate characterizing someone’s brain responses to a specific action is possible. As this research topic has to deal with different fields and there are not previous researches that conveys both. The core idea is to provide enough elements to form the foundations in both areas and propose a scheme to do so. Materials and methods. This section sum-marizes basic elements of interaction between lear-ners and computers that allows us to integrate them. It will show how some responses named cognitive neuroscience variables are a good source of infor-mation for user profiling and will illustrate how this researched field especially used in neuroscience can be effectively used for this purpose. In other words, this paper is going to show the reader how some reactions to exposed actions can be tracked and characterized. results. It discusses some issues to take into account for developing the proposed profi-ling scheme and shows how human brain responses can be used to acquire the necessary information to feed an intelligent profiling system. These assump-tions allow researchers to account different pheno-mena and use them for different purposes like the one being developed in this work: Learner Profiling. conclusiones. Algunas ventajas y desafíos del Per-filamiento de Aprendices se enumeran y se invita a los investigadores a aplicar esta tecnología en otros campos y a ampliar esta aplicación, especialmente en el contexto enseñanza-aprendizaje.Item Adecuación del esfuerzo terapéutico en pacientes críticamente enfermos o terminales: una metodología multidisciplinaria centrada en el respeto al individuo(Corporación Universitaria Lasallista, 2014-10-18) Navarro Estrada, StellaIn current times, medicine responds to a scheme in which scientific knowledge is used to get a response that aims to remedy a specific pathology. But several phenomena, such as disease, disability and death are closely linked, having blurred limits and making science insufficient to propose an answer to human suffering. In these situations, it is necessary to create new treatment schemes that allow the consideration of multiple elements that go beyond science to, again, focus on the dignity and the necessities of the human being. This study, therefore, focuses on evaluating the complexity of several events that take place in advanced or terminal pathologies in order to create a plan that can be adapted to the individual. Beyond medical futilities and the autonomy, a methodology that involves medical, ethical, personal, relational, cultural, social and economic aspects is proposed, in order to provide an integral attention to the individual.Item Adición de Enterococcus faecium mejora poblaciones celulares inmunes y anticuerpos vacunales de lechones destetos(Corporación Universitaria Lasallista, Editorial Lasallista, 2016) Herrera Franco, Víctor H.; Ciro Galeano, Johana; Parra Suescún, Jaime EduardoAnimals are subjected, at the moment the sucking pig cannot produce an adequate immunological activity, to several stress types during waning, due to the fact that the passive immunity acquired at the colostrum is gradually reduced and the sucking pig has a low immunological response during post weaning. Objective. Determine the effect of probiotics (Lactobacillus acidophilus, Lactobacillus casei and Enterococcus faecium) on the populations of immune cells in the blood of weaners. Materials and methods. The experiment was made with 80 weaners with 2 days of age, fed with two diets: commercial diet with and without probiotics. For the first, different probiotics were added in the weaner ́s water. A blood sample was taken from the jugular vein at the 1, 15 and 30 post weaning days. A randomized blocks design was used, arranged with repeated measures during time. Every animal was randomized to one of 15 treatments (5 diets*3times). Results. A significant increase (P<0.01) in the number of immune blood cells and of the number of vaccine antibodies in the animals that consumed E. faecium, in comparison to those that consumed the diet with antibiotics. Conclusions.E. faecium improves the animal ́s response to stressful stimuli such as weaning, having a controlled increase of immune blood cellsItem Aislamiento de consorcio de microorganismos degradadores de cianuro(Corporación Universitaria Lasallista, 2006) Garcés Molina, Adelaida María; Agudelo Betancur, Lina Marcela; Macías Mazo, Karina Isabel; Salinas Alzate, Natalia AndreaIntroduction. Cyanide is used in the mining industry to recover gold, in the shape of a solution, from mother material. This compound is highly toxic and generates great environmental problems, therefore several physical and chemical technologies have been developed to solve them. Materials and methods. Three microogranisms´ consortiums were isolated from soils coming from gold mines in the municiple of Amalfi, Antioquia, where the gold extraction is made with mercuriy. o select the most efficient microorganisms the consortiums were cultivated in nutritive broth, increasing the potasium cyanide concentration from 2x10-4 ppm to 2000 ppm. All the process was made under aerobic and anaerobic conditions. Later, the nutritive broth was replaced, step by step, with minimum mineral medium, with 2000 ppm of potasium cyanide as a source of carbon and nitrogen. All the cultivation mediums were prepared at a pH value of 7. During this last stage, the consumed cyanide was quantified with a cyanide selective ion electrode. Results. During the development of this work consortiums of microorganisms were isolated from soils coming from mining zones, and their efficiency for the degradation of potasium cyanide was determined. Conclusion: The biological degradation can be a better alternative to eliminate this contaminant.Item Alcances de la fe en la época contemporánea(Corporación Universitaria Lasallista, 2008) Arteaga Tobón, EdwinIn a laicized world like the Western, which looks for orientation, faith is carefully heard, even though its proposals are not always accomplished. Christian faith counts and will continue counting, on further achievements, a fact which we cannot have doubt about.Item Alfabetización académica: leer y escribir desde las disciplinas y la investigación(Corporación Universitaria Lasallista, Editorial Lasallista, 2016) Sánchez Upegui, Alexánder ArbeyThis is an article to reflect, and it comes from a research work in which some considerations about writing in the university environment using academic literacy and notions such as writing throughout the curricula and the disciplines and the speech genres as bases. The context of the reflections are the difficulties to write expressed by graduate students and researchers during a workshop-seminar developed between 2011 and 2016 about academic-research writing, a proposal that came from the research activities applied in the Linguistics PhD programItem Alfabetización académico-investigativa: citar, argumentar y leer en la red(Corporación Universitaria Lasallista, Editorial Lasallista, 2013) Sánchez Upegui, Alexánder Arbey; Sánchez Ceballos, Lina María; Méndez Rendón, Juan Camilo; Puerta Gil, Carlos AugustoFrom a textual-linguistic focus, this article exposes a series of considerations about literacy in the universi-ty using three key categories as a base: intertextua-lity, argumentative writing and reading online, within the informational literacy framework. These are in-terdependent and central concepts to strengthen the communicative development within the context of a superior order academic literacy, directly involving the disciplines, the research processes and the tea-ching-learning practices in higher education, given the fact that knowledge is a discursive construction.Item Algoritmo de detección en modo isla de un inversor, basado en la medición del segundo armónico(Corporación Universitaria Lasallista, 2013-09-24) Velasco, David; Trujillo Rodríguez, César; Hernández Mora, JohannIntroduction. This paper introduces a new method of islanding detection for distributed energy generation systems. Objective. To demonstrate that, with the method proposed, it is possible to achieve detection time measurements within the security margins defined by the regulations. Materials and methods. The method was implemented on a 230 W inverter. This method is based on the introduction of a disturbance at the inverter´s output and the subsequent observation of the tension in the common coupling point (CCP), which depends on the impedance connected to the latter, in an islanding situation. The islanding detection is based on the Fourier´s analysis. Results. Simulation and experimental results are provided, under several load and net conditions, achieving, in all cases, adequate detection times, not affecting the inverter´s performance in terms of harmonic distortion or reactive power. Conclusions. The method proposed, if compared to others based on the injection of harmonics, can detect the islanding situation by the use of the Fourier´s analysis applied to a unique harmonic, with no degradation of the power quality and within the time periods defined by the regulations.Item Algoritmos meta heurísticos para el aprendizaje de redes bayesianas(Corporación Universitaria Lasallista, Editorial Lasallista, 2018) Oviedo, Byron; Puris, Amilkar; Zhuma, EmilioIntroduction This article aims to obtain models based on probabilistic case analysis to help decision-making in the education and learning of UTEQ students. To obtain the final product, the development process has been distributed in several stages. Objective To create a probabilistic model to evaluate and diagnose students based on a set of characteristics, which must be learned automatically through a generalization of the AutoClass model allowing the existence of hidden variables, each of them affecting a set different from observable variables (students’ answers to questions raised by an automatic learning system). Materials and methods. Our study will be carried out to define another form of structural learning based on the search of structures through evolutionary metaheuristic models. Results This model will allow the authorities of the UTEQ to identify inconveniences and setbacks in the teaching-learning process. At the same time, the results obtained will allow immediate decision-making to solve the problems detected and thus fulfill the institutional mission of training professionals with a scientific and humanistic vision capable of developing research, creating technologies, maintaining and disseminating our ancestral knowledge and culture, for the construction of solutions to the problems of the region and the country. Conclusions were metaheuristic variable mesh optimization (VMO) to structural learning of Bayesian network classifiers (BVMO).Item Algunas características de la mortalidad por homicidio en Colombia. 1985 a 2001(2005) Rodríguez Gázquez, María de los ÁngelesIntroduction: Colombia has the sad reputation of being one of the most violent countries in the world, and this situation is harder due to an armed conflict that has lasted more than five decades and that has put our country in the group of very few countries with such long conflicts. Objective: To evaluate the evolution of the homicide rates in the 1985-2001 period, according to the sex, age group and position variables, in the first death causes. Materials and methods: A descriptive study of death by homicide that uses as main source the death registrations of intentional injuries made by other persons (ICD-9: E960-E968, ICD -10: X85-Y09). Results: In the 1985- 2001 period, 402375 deaths by homicide were registered in Colombia. The risk of dying by homicide showed an ascendant lineal trend. This risk was bigger among the male population and in the age group between 15-45 years. From 1987 homicide was the first death cause in all of the population. Conclusion: Colombia shows high homicide rates, in fact higher than those showed worldwide.Item La Alianza del Pacífico y los Brics: dos modelos de competitividad país(Corporación Universitaria Lasallista, Editorial Lasallista, 2019) Cazallo Antúnezt, Ana María; Meñaca Guerrerottt, Indira; Lechuga Cardozo, Jorge Isaac; García Guiliany, Jesús EnriquettttttThe importance of this research lies in the behavior of the countries belonging to the two groups during the 2012-2017 period in terms of competitiveness and how this variable has allowed them to position themselves at a global level. Objective: This article analyzes the existence of significant differences in the competitiveness models of the economic blocs (Pacific Alliance and BRICS) using as discriminatory variables the twelve pillars of the global competitiveness index of the World Economic Forum. Materials and methods: The methodology used is quantitative analytical and uses the statistical technique of discriminant analysis as a mechanism to determine which variables allow an effective classification with respect to the countries belonging to one bloc or another. Results: The results obtained denoted that of the twelve (12) variables introduced in the model, onlysix (6)–macroeconomic environment, healthand primary education, higher education andtraining, labor market efficiency, financialmarket development and size of the market,have a discriminatory component in terms ofcountry competitiveness. Conclusions: Themodel to measure country competitiveness wassignificant, allowing to have a high predictivecapacity since one hundred percent of theclassification was correctItem Alternativas antropológicas, históricas y pedagógicas, para la conservación del sujeto en el universo digital(Corporación Universitaria Lasallista, 2015-09-07) Betancourt Cadavid, Jorge HernánIn the contemporary world, especially within the digital universe, conceptualizing the subject constituted in this reality is a mandatory exercise. A reflection on the matter, being especially careful of universalizing intentions is necessary. This research work aims to a view that breaks the separation between what is real as an external aspect and subjectivity, in order to re-define the idea of objectivity related to formation. Therefore, from the method provided by hermeneutics as a way for interpretation, the article tries to approach subjectivity without any operative positions taken from the positivist reductions and also without the bold locution of macro historical processes defined by the digital world. This is a reflection funded on the contents that appear in the historical and transience conditions of the subjects, remarking the emergence non-hegemonic social relationships.Item El amigo en Aristóteles como posibilidad de autoconocimiento y las diferencias con un adulador(Corporación Universitaria Lasallista, 2017) Garcés Giraldo, Luís Fernando; Huertas Díaz, Omar; Arboleda López, Adriana PatriciaFrom the aristotelean perspective, the differences between a friend and a flatterer are established, describing the essential elements which constitute a true friendship relationship, where elements of ethics as an essential virtue and self-knowledge come together. In this sense, it is established, following the Stagirite, that one have a friendship relationship without these conditions: 1) doing good, or what seems to be good, to others; 2) wishing that your friend exists and loves for the love of their own friend; 3) spending time with and choosing the same things as your friend; 4) sharing your friend’s happiness and sorrows. Conversely, there can be no friendship if there are no conditions of equality, similar virtue and reciprocity between friends; where one wishes good for the other as much as for oneself.Item An approach between tools for the analysis of tendencies and business innovation management(2016) Sepúlveda Aguirre, Jovany A.; Garcés Giraldo, Luís Fernando; Serrano García, Jakeline; Gómez Molina, Huber F.Currently, there is a number of tools which allow analyzing information-based behavioral patterns; in the specific case of this article, the analysis of tendencies will be highlighted not only as a tool to predict the behavior of prices in order to measure and process financial market information but also, in a wider standpoint, to take tendencies as a tool to analyze the behavior of certain elements within a specific environment and period of time. Accordingly, the article is intended to set the theoretical, conceptual, and contextual basis necessary to perform the analysis of tendencies through the combination of a monitoring system and an observatory intended to organize, quantify, process, and use information as an indispensable element to implement innovation in the business field.Item Análisis cualitativo sobre los factores que motivan la adopción de techos verdes(Corporación Universitaria Lasallista, Editorial Lasallista, 2019) Valencia Grajales, Andrea María; Ruiz Herrera, Luis Germán; Valencia Arias, Alejandro; Valencia Grajales, José FernandoThe existence of densely populated areas, but without adequate planning of their green areas, is a common problem in the Colombian territory. This problem is addressed in the present investigation, seeking to examine the factors that encourage the adoption of green roofs in new horizontal property projects. Materials and Methods: To investigate the above, this study proposes an analytical methodology with documentary means derived from research results worldwide and in-depth interviews with private and public entities and citizens about the viability of the adoption of green roofs. Results: Among the results obtained, it was found that factors such as temperature, energy and quality of life influence the adoption of green roofs. Conclusion: The motivations and expectations of government entities, construction companies and users intervene directly with the use and usefulness of technology, in such a way that a better quality of life is generated in the inhabitants.
