Résumé La politique de colonisation interne au Brésil après l’Indépendance a été continuellement activée et transformée au cours des XIXe et XXe siècles afin de contrôler les populations insoumises et les territoires. À partir de l’analyse bibliographique et documentaire d’un ensemble de projets et d’expériences de colonisation, il a été possible de reconstruire le cadre interprétatif de cette politique, en mettant l’accent sur la période de la dictature entreprise-militaire et sur son sens de transformation des paysans en classe moyenne rurale. Nous avons cherché à identifier les principaux éléments constitutifs de cette couche sociale, ses caractéristiques et ses attentes en fonction de l’ensemble des valeurs, intérêts et présupposés du complexe techno-entreprise-militaire à partir de la politique de colonisation dans sa formation. Les continuités et reconfigurations de cette politique nous permettent d’affirmer que coloniser est le verbe caché dans le traitement de la question agraire nationale. lIndépendance l Indépendance territoires lanalyse analyse dun d un dexpériences expériences laccent accent entreprisemilitaire entreprise militaire rurale sociale lensemble valeurs technoentreprisemilitaire techno formation daffirmer affirmer nationale

Abstract The internal colonization policy in post-Independence Brazil was continuously activated and transformed throughout the 19th and 20th centuries in order to control unsubmissive populations and territories. From the bibliographic and documentary analysis of a set of colonization projects and experiences, it was possible to reconstruct the interpretative framework of this policy, emphasizing the period of the corporate-military dictatorship and its meaning of transformation of the traditional peasantry into the rural middle class. We sought to identify the main elements that constitute this stratum, its characteristics and expectations based on the set of values, interests and assumptions of the techno-corporate-military complex, highlighting the role of the colonization policy in its formation. The continuities and reconfigurations of this policy allow us to state that talking about colonizing while it is the hidden verb of the treatment given to the national agrarian question. postIndependence post Independence th territories experiences corporatemilitary corporate military class stratum values technocorporatemilitary techno complex formation question

Resumen: La investigación determinó el efecto de la mediación de un videojuego educativo en el fortalecimiento de la resolución de problemas de matemáticas. El método cuantitativo con alcance descriptivo fue aplicado. La muestra fue no probabilística con 20 estudiantes de la Institución Educativa San Jorge, en la vereda Las Damas, Municipio de Purificación, Departamento de Tolima. Las variables estudiadas fueron: desempeño en resolución de problemas, mecánicas y percepción del videojuego. La encuesta inicial reflejó que un 90% no poseían habilidades matemáticas básicas y tenían una percepción negativa del área. Entonces, fue diseñada una estrategia educativa con un videojuego denominado Corredor Matemático de Pensamiento Variacional (Comapeva), en tercera persona con Unity 3D, Adobe Ilustrator y Autodesk 3d. Fue protagonizado por Comaco: joven aventurero que superó retos matemáticos. El guion narrativo combinó elementos del constructivismo, Aprendizaje Basado en Retos (ABR) y modelo instruccional ADDIE (Análisis, Diseño, Desarrollo, Implementación y Evaluación). La herramienta fue implementada con el apoyo de los docentes. Con el videojuego el 100% de los estudiantes resolvieron retos con diversas estrategias. Disminuyó un 21% el tiempo de desarrollo de los problemas, y un 33% las solicitudes de apoyo del docente. La concentración, atención, memoria, agilidad mental, interpretación y análisis fueron fortalecidas. El videojuego facilitó la construcción de conocimientos en matemáticas de forma sustancial. En consecuencia, fue innovador, motivador y permitió la trasformación de prácticas educativas según las necesidades de aprendizaje.

Abstract: The research considers the effect of the mediation of an educational video game in strengthening mathematics problem solving. The quantitative method with a descriptive scope was applied. The sample was non-probabilistic with 20 students from the San Jorge Educational Institution, in Las Damas village, Municipality of Purificación, Department of Tolima. The variables studied were problem-solving performance, game mechanics, and videogame perception. The initial survey showed that 90% of the students did not have basic mathematical skills and had a negative perception of the subject area. Therefore, an educational strategy was then designed using a video game called the Variational Thinking Mathematical Corridor (Comapeva). The game was developed in third person using Unity 3D, Adobe Illustrator, and Autodesk 3d. It starred Comaco: a young adventurer who overcame mathematical challenges. The narrative script combined elements of constructivism, Challenge-Based Learning (CBL) and instructional model ADDIE (Analysis, Design, Development, Implementation and Evaluation). The tool was implemented with the support of the teachers. With the video game, 100% of the students were able to solve challenges using various strategies. Problem development time decreased by 21%, and teacher support requests decreased by 33%. Concentration, attention, memory, mental agility, interpretation, and analysis skills were all strengthened. The video game facilitated the construction of knowledge in mathematics in a substantial way. Consequently, the video game was found to be innovative and motivating, and it allowed for the transformation of educational practices according to the students' learning needs.

Abstract Incorporating BIM in the education of professionals has become a demand and a topic of high importance for higher education. Several proposals for a curricular implementation of BIM exist. However, in most cases, they are specific to a single university or domain, do not consider academic policies or simplify practice by segmenting knowledge. This work proposes a protocol for the curricular implementation of BIM similar to the industry, considering aspects of process, technology, and policies aligned with the educational institution's mission and with existing competencies. Action research was the used method. Three actions were conducted: (1) proposition, (2) systematization and (3) application. The actions were executed in cycles incrementally, resulting in (1) guidelines, (2) supporting tools and (3) implementation plans. Two Brazilian universities participated in pilot studies of Project Construa Brasil. The pilot studies inspired a network of BIM cells that have synchronously applied curricular BIM implementation guidelines on a large scale. The guidelines proved to be generic and comprehensive, guiding the transformation with an empirical basis for the academics' decision-making. Leadership of a BIM specialist was confirmed as an essential factor of success. It is observed that even with a timid introduction of BIM competence in a limited scope of engineering solutions, the impact on the BIM maturity curriculum is significant. exist However cases domain knowledge industry process technology institutions institution s competencies method conducted 1 (1 proposition 2 (2 3 (3 application incrementally plans Brasil scale comprehensive academics decisionmaking. decisionmaking decision making. making decision-making success solutions significant (

RESUMEN En el contexto actual, la transformación digital se ha convertido en un factor fundamental para el cambio de la matriz productiva en Ecuador. Esto se debe a que el mundo está siendo cada vez más digital y las empresas necesitan adaptarse a esta nueva realidad para seguir siendo competitivas en el mercado nacional e internacional. Sin embargo, a pesar de los esfuerzos del gobierno ecuatoriano por impulsar la transformación digital, todavía existen obstáculos que limitan su implementación de manera eficiente y efectiva. Uno de ellos es el insuficiente conocimiento sobre el tema y sobre sus beneficios para la práctica social. Muchas empresas todavía no han adoptado las tecnologías digitales en sus procesos y actividades. Por otro lado, existen barreras como la falta de acceso a internet en algunas zonas rurales y la falta de capacitación y formación en habilidades digitales. El objetivo de este estudio es ofrecer un análisis de los niveles de interdependencia intersectorial en el contexto de la matriz productiva de Ecuador, identificando los principales desafíos, fortalezas y oportunidades. De esta manera se podrán proponer recomendaciones para la integración efectiva con la transformación digital. La metodología consistió en revisar la literatura sobre la transformación digital y su integración a la matriz productiva de Ecuador. También se recopiló información de estudios y datos estadísticos sobre la adopción de tecnologías digitales en el país.

ABSTRACT In the current context, digital transformation has become a key factor for changing the productive matrix in Ecuador. This is because the world is becoming increasingly digital and companies need to adapt to this new reality to remain competitive in the domestic and international markets. However, despite the Ecuadorian government's efforts to promote digital transformation, there are still obstacles that limit its efficient and effective implementation. One of those obstacles is the insufficient knowledge about the subject and about its benefits for social practice. Many companies have not yet adopted digital technologies in their processes and activities. On the other hand, there are barriers such as the lack of access to the internet in some rural areas and the lack of training and skills in digital skills. The objective of this study is to offer an analysis of the levels of intersectoral interdependence in the context of Ecuador's productive matrix, identifying the main challenges, strengths and opportunities. In this way, recommendations can be proposed for effective integration with digital transformation. The methodology consisted of reviewing the literature on digital transformation and its integration into Ecuador's productive matrix. Information was also collected from studies and statistical data on the adoption of digital technologies in the country.

Abstract The Plans for the Social Organization of Rural Property (POSPR) in Colombia would allow the implementation of the Integral Rural Reform (RRI), an essential component of the Peace Agreements. Specifically, POSPR’s institutional design in Ovejas (a municipality in the Department of Sucre) would enable the implementation of the RRI. Information from interviews with key actors, the review of national legislation, and the use of software to elaborate databases show that, in this locality, plans to incorporate hectares into the Land Fund and the delivery of land titles strengthen community participation with gender equity and guarantee territorial planning. However, the gradual suspension of these plans at the national level has halted the progress of rural reform. Ovejas would be the only municipality complying with this point of the Peace Agreements.

Resumen Los planes de ordenamiento social de la propiedad rural (POSPR) en Colombia permitirían la implementación de la reforma rural integral (RRI), componente esencial del Acuerdo de Paz. De manera puntual, se argumenta que el diseño institucional del POSPR de Ovejas, municipio del Departamento de Sucre, posibilitaría la ejecución de la RRI. La información de entrevistas a actores clave, la revisión de legislación nacional y la elaboración de matrices en un software muestran que, en esta localidad, los planes de incorporación de hectáreas al Fondo de Tierras y de entrega de títulos de propiedad fortalecen la participación comunitaria con equidad de género y garantiza el ordenamiento del territorio. No obstante, la suspensión paulatina a escala nacional de estos planes ha detenido el avance de la reforma rural. Ovejas sería el único municipio que estaría cumpliendo con este punto del Acuerdo de Paz.

ABSTRACT This study was conducted under the qualitative paradigm, employing data collection techniques, description, analysis, and interpretation, with a participatory action and rural participatory diagnostic design. The general objective was to determine the impact of innovation on sustainable agri-food systems. The "working with people" model was followed to engage with farmers and diagnose the advantages, strengths, and challenges they face in implementing innovation policies, specifically in educational innovation, using training and capacity-building methodologies for farmers, support teams, and technical assistance. It was concluded that educational innovation is the central axis to be integrated for the transformation of sustainable and resilient food systems, ensuring food sovereignty. Such innovation enables the development of conservation family farming, with respect for nature, genetic resources, and the cultural identity of rural areas.

RESUMEN El presente trabajo se desarrolló bajo el paradigma cualitativo, con la aplicación de técnicas de recolección de datos, descripción, análisis e interpretación, con un diseño de acción-participativa y diagnostico rural participativo. El objetivo general se desarrolló en función de la determinación del impacto de la innovación en los sistemas agroalimentarios sostenibles. Se siguió el modelo de trabajo con la gente (working with people) para vincularse con los agricultores y de esa forma diagnosticar las ventajas, fortalezas y dificultades que presentan para implementar políticas de innovación, particularizada a la innovación educativa, con metodologías de formación y capacitación a los agricultores, equipos de apoyo y asistencia técnica. Se concluyó que la innovación educativa es el eje central a integrar para la transformación de los sistemas alimentarios sostenibles, resilientes, garantizando la soberanía alimentaria, ya que tal innovación permite el desarrollo de la agricultura familiar de conservación, con respeto a la naturaleza, recursos genéticos y la identidad cultural de las zonas rurales.

ABSTRACT The objective of this research was to analyze the effects of digital transformation in the accounting and financial sector in Ecuador. To achieve this objective, three specific objectives were established, which were: to identify the changes that digital transformation has generated in accounting and financial processes in Ecuadorian companies from various industrial sectors, to analyze the perceptions of accountants and financiers about the adoption of digital technologies in their daily tasks and how it affects their work performance, and evaluate the effectiveness of the technological solutions implemented in the accounting and financial sector in Ecuador, in terms of efficiency, cost reduction and improvement in decision making. To carry out this research, a non-experimental cross-sectional research design was used and a questionnaire was applied to 150 accountants and financiers from different companies in Ecuador. The results of the research indicate that digital transformation has had a positive impact on the accounting and financial sector in Ecuador, since it has allowed greater efficiency in processes, cost reduction, and improved decision-making. Likewise, accountants and financiers perceive that the adoption of digital technologies in their daily tasks has improved their work performance and has allowed them to focus on more strategic tasks. Regarding the technological solutions implemented in the accounting and financial sector, it was found that the most used are accounting and finance software, business resource management systems and document management systems. These solutions have proven to be effective in improving processes and reducing costs.

Estas soluciones han demostrado ser efectivas en la mejora de los procesos y en la reducción de costos.

Abstract Using the epistemological instrument of historical and dialectical materialism, embodied in the critique of the legal form of Pachukanis, with the procedural modality attributed to it by Edelman, consisting of formulating theoretical developments from the immanent critique of judicial decisions, the article investigates the relations between law and violence, especially in light of its impact on social movements, from the case study of the legal dispute surrounding the removal of the statue of a Confederate general in the city of Richmond, Virginia. In the end, it is concluded that, even when the state welcomes the interest of a critical social movement, as in the case in question, it does so in order to reaffirm the mechanisms of reproduction of the legal form that imprisons the contesting movements and prevents them from advancing towards the transformation of the mode of production. materialism Pachukanis Edelman decisions violence Richmond Virginia end movement question production

Resumo Valendo-se do instrumental epistemológico do materialismo histórico dialético, consubstanciado na crítica da forma jurídica de Pachukanis, com a modalidade procedimental que lhe atribuiu Edelman, consistente em formular desenvolvimentos teóricos a partir da crítica imanente de decisões judiciais, o artigo investiga as relações entre direito e violência, especialmente à luz de sua incidência na atuação de movimentos sociais, a partir do estudo de caso da disputa judicial em torno da remoção da estátua de um general confederado na cidade de Richmond, Virginia. Ao final, conclui-se que, ainda quando o estado alberga o interesse de um movimento social crítico, como no caso em exame, o faz de forma a reafirmar os mecanismos de reprodução da forma jurídica que aprisiona os movimentos contestatórios e impede que avancem em direção à transformação do modo de produção.

Abstract The purpose of this text is to carry out as analysis of the decisions issued in the second instance involving family members of prisoners, focusing on the Courts of Justice of Minas Gerais, São Paulo and Rio de Janeiro. Decisions published between 1998 and 2021 were collected in the three locations, forming a database, that was scrutinized in a quantitative perspective. Based on this, it was possible to notice that the judicial processes have two main focuses: requests related to the excess term of provisional detention and requests related to difficulties in visiting prisons. In the first point, the importance of families in the persecution of the rights of the inmates is clear. The decisions of the three courts on the matter differ substantially, and the claim is only effective in many cases in Rio de Janeiro. On the second point, there is an indication of how imprisonment goes beyond the person of the prisoner to reach their loved ones. In these cases, the decisions of the three courts have contributed to the transformation of family members of prisoners, especially women, into criminals, authorizing the constant surveillance of their bodies, in addition to the denial or hardening to maintain the bonds of affection between these and their prisoners. prisoners Gerais Janeiro 199 202 locations database perspective focuses prisons point clear substantially ones women criminals bodies 19 20 1 2

Resumo A proposta deste texto é analisar as decisões proferidas em segunda instância que envolvem familiares de presos, com foco nos Tribunais de Justiça de Minas Gerais, São Paulo e Rio de Janeiro. Foram coletados acórdãos publicados entre 1998 e 2021 nas três localidades, formando uma base de dados, escrutinada posteriormente numa perspectiva quantitativa. Foi possível notar que os processos judiciais têm dois focos principais: pedidos relacionados ao excesso de prazo da prisão provisória e pedidos relacionados às dificuldades na visitação em unidades prisionais. No primeiro ponto, fica clara a importância das famílias na busca de concretização dos direitos dos custodiados. As decisões dos três tribunais sobre a questão divergem substantivamente, sendo que o pleito só se efetiva em muitos casos no Rio de Janeiro. Já sobre o segundo ponto, tem-se um indicativo de como o aprisionamento ultrapassa a pessoa do preso para atingir seus entes queridos. Nesses casos, as decisões das três corte têm contribuído para a transformação, sobretudo, de familiares de presos, em especial mulheres, em criminosas, autorizando a vigilância constante de seus corpos, e dificultado a manutenção dos vínculos de afeto entre essas e seus entes presos. presos Gerais Janeiro 199 202 localidades dados quantitativa principais prisionais ponto custodiados substantivamente temse tem queridos transformação sobretudo mulheres criminosas corpos 19 20 1 2

Resumo Os dispositivos estatais para o governo das águas no Brasil vêm sendo fortemente influenciados pelo discurso do desenvolvimento, tendo como principal instituição multilateral promotora o Banco Mundial, cujas diretrizes convergem para o afastamento das instituições estatais do papel de provedoras dos serviços de água e promovem a perda do controle sobre as águas por populações locais. Neste artigo, analiso a trajetória das políticas governamentais para a gestão das águas no Brasil a partir da instituição da Política Nacional de Recursos Hídricos (PNRH) à luz da literatura antropológica sobre grandes projetos de desenvolvimento, administração pública e o campo autodenominado de antropologia da água, observando o processo de criação e implementação de dispositivos institucionais que abrem caminho para a transformação da água em uma commodity. A pesquisa foi realizada por meio de observação participante em avaliação oficial da PNRH e análise de relatórios de projetos do Banco Mundial. desenvolvimento Mundial locais artigo (PNRH commodity

Abstract State devices for water governance in Brazil have been strongly influenced by the development discourse, with the World Bank as the main multilateral institution that promotes it, whose guidelines converge towards the removal of state institutions from the role of providers of water services and promote the loss control over water by local populations. In this article, I analyze the trajectory of government policies for water management in Brazil from the institution of the National Water Resources Policy (NWRP) under the light of anthropological literature on large development projects, public administration and the self-declared field of anthropology of water, observing the process of creation and implementation of institutional devices that pave the way for the transformation of water into a commodity. The research was carried out through participant observation in an official evaluation of the NWRP and analysis of project reports from the World Bank. discourse it populations article (NWRP projects selfdeclared self declared commodity

Resumen: Con la reforma neoliberal del sistema previsional chileno en 1981, América Latina inauguró un proceso de transformación de los fondos de pensiones. Estos cambios económicos han generado una racionalidad política que ve a la vejez como carga social y conceptualiza a las personas mayores de forma similar a grupos de población con identidades subordinadas. Este artículo explora la contradicción entre el fracaso económico de estas reformas y su actual legitimidad política como modelo de gobernanza de los sistemas de pensiones, con el consecuente impacto en la comprensión del envejecimiento demográfico como causa del déficit fiscal de los Estados.

Abstract: With the neoliberal reform of the Chilean pension system in 1981, Latin America inaugurated a transformation of its pension funds. These economic changes have also generated a political rationality that sees old age as a social burden, assimilating the elderly to other subordinate identities. This article explores the contradiction between the economic failure of these reforms and their current political legitimacy as a model of governance of pension systems, a model that understands demographic ageing as a cause of the fiscal deficit of states.

Abstract: This article seeks to analyze the socialist views on Argentine federalism, which have not been a subject of specific attention by historians. With this purpose, the emphasis is put on a precise aspect such as the one represented by the National Territories, spaces that depended on the federal government, even though they were considered as future provinces from their very origin. As is shown in this paper, the Socialist Party stood against the creation of new provinces, a consequence of the party’s unfavorable judgment of Argentine federalism. This disapproval continued until 1932 when different circumstances led the party to a federal turn that made it become a supporter of the transformation of Territories into provinces. The examination of this trajectory sheds light on less studied aspects of one of the most important political parties in Argentina in the 20th century.

Resumen: En este artículo se exploran las miradas socialistas en torno al federalismo argentino, las cuales no han sido objeto de atención específica por parte de la historiografía. Para ello se pone foco en una dimensión puntual, como fue la representada por los Territorios Nacionales, espacios que constituían dependencias del gobierno federal, pero que desde su origen fueron concebidos como futuras provincias. Como aquí se demuestra, el Partido Socialista mantuvo una postura adversa a la creación de nuevas provincias, consecuente con el juicio negativo que dicha fuerza política tenía respecto del federalismo argentino. Ese rechazo persistió hasta 1932, cuando un conjunto de circunstancias condujo al partido a consumar un giro federal que lo llevó a convertirse en impulsor de la transformación de los Territorios en provincias. El examen de esta trayectoria echa luz sobre aspectos poco estudiados de uno de los partidos políticos más importantes de la Argentina del siglo XX.

Abstract Agroecological and artisanal produce markets have multiplied as part of a broader process that promotes food citizenship oriented towards justice and sustainability. However, this phenomenon is immersed in the complexity of food systems and entails great heterogeneity. This article analyzes the relationship between these types of initiatives and the gentrification processes in some of the areas where they are established. The topic is approached from ethnographic material collected in the framework of a research project on agroecological production initiatives and artisanal transformation in Mexico City and on the citizens’ collectives that facilitate the commercialization of this production. The findings show that in certain areas of the city these markets shape a broader set of “alternative” food supply networks linked to gentrification processes and the findings identify some of the factors that affect the reproduction of social inequalities within the framework of these initiatives. At the same time, the study underscores the agency of the actors involved and documents their abilities to use these spaces through the growing demand for fresh, healthy, and locally-sourced food to advance their own ends in areas subject to gentrification.

Resumen Los mercados de producción agroecológica y artesanal se han multiplicado como parte de un proceso más amplio que busca impulsar ciudadanías alimentarias orientadas a la justicia y la sustentabilidad. No obstante, este fenómeno se encuentra inmerso en la complejidad de los sistemas alimentarios y alberga gran heterogeneidad. En el presente artículo se analizan las relaciones entre este tipo de iniciativas y los procesos de gentrificación de algunas de las áreas donde se establecen. El tema es abordado a partir del material etnográfico recolectado en el marco de un proyecto de investigación enfocado en la documentación de iniciativas de producción agroecológica y la transformación artesanal que operan en la Ciudad de México y en los colectivos ciudadanos que facilitan la comercialización de sus productos. Los hallazgos muestran que en ciertas zonas de la ciudad estos mercados intervienen en un conjunto más amplio de oferta alimentaria “alternativa” vinculada a los procesos de gentrificación e identifica algunos de los factores que inciden en la reproducción de las desigualdades sociales en el marco de estas iniciativas. Al mismo tiempo, se visibiliza la agencia de los actores y se documenta su capacidad de utilizar el espacio de oportunidad creado por la creciente demanda de alimentos frescos, saludables y de origen local en las zonas sujetas a procesos de gentrificación para avanzar hacia sus propios fines.

ABSTRACT • The possible production of fructo-oligosaccharides from sucrose was evaluated in the Base Business Unit (UEB) “Ignacio Agramonte'”, which currently produces sorbitol, with low exploitation of the installed capacity, due to lack of glucose. There was an opportunity in infrastructure, time and labor to convert the entity into a multipurpose plant. A simulation model of the technology for the production of fructo-oligosaccharide syrup from sucrose was developed, based on the enzymatic transformation of sucrose into fructo-oligosaccharides, using the recombinant enzyme 1-SST (1-sucrose: sucrose fructosyltransferase) expressed in Pichia pastoris, obtained at the Center for Genetic Engineering and Biotechnology at Sancti Spiritus. Model validation yielded relative errors lesser than 5 %. Two improvement alternatives were evaluated based on increasing the production of FOS by using the actual installed capacity in the sorbitol factory (alternative 1) and also increasing the initial concentration of the sucrose solution (alternative 2). Feasibility of the alternatives was evaluated by comparing the annual net cash income (Anci) and expenses. Alternative 2 was the best, producing 841,5 t of fructo-oligosaccharides in 90 working days, with a benefit/cost ratio of 1,2.

RESUMEN • Se evaluó la posibilidad de incorporar la produccón de fructo-oligosacáridos a partir de sacarosa en la Unidad Empresarial de Base (UEB) “Ignacio Agramonte” que produce actualmente sorbitol, con un bajo aprovechamiento de la capacidad instalada por falta de glucosa, existiendo oportunidad en infraestructura, tiempo y mano de obra para convertir la entidad en una planta multipropósito. Se desarrolló un modelo de simulación de la tecnología de producción de sirope de fructo-oligosacáridos a partir de sacarosa, basada en la transformación enzimática de la sacarosa en fructo-oligosacáridos, utiizando la enzima recombinante 1-SST (1-sacarosa: sacarosa fructosiltransferasa) expresada en Pichia pastoris, obtenida en el Centro de Ingeniería Genética y Biotecnología de Sancti Spiritus. La validación del modelo arrojó errores relativos menores que el 5 %. Se evaluaron dos alternativas de mejoras a partir de aumentar la producción de FOS al utilizar la capacidad real instalada en la fábrica de sorbitol (alternativa 1) y además aumentar la concentración inicial de la solución de sacarosa (alternativa 2). Se evaluó la factibilidad de las alternativas al comparar la ganancia anual después de impuestos (Anci) y los egresos. La alternativa 2 resultó la mejor, produciéndose con ella 841,5 t de fructo-oligosacáridos en 90 días de trabajo, con una relacion beneficio / costo de 1,2.
