O espaço costeiro consiste em um ambiente altamente dinâmico que se encontra em constantes mudanças, em função tanto de fatores naturais como agentes antrópicos. Sabendo disso, a erosão constitui um processo natural de evolução que compõe a dinâmica geomorfológica da zona costeira, moldando feições como as falésias. Contudo, tal fenômeno tem sido intensificado em função da ocupação e avanço da urbanização no litoral e, em consequência disso, tem gerado grandes impactos sobre o (ecos)sistema costeiro, a população e as atividades desenvolvidas nessas áreas. Tendo isso em vista, o intuito dessa pesquisa foi analisar, através do levantamento bibliométrico, o crescimento das discussões, na comunidade científica e acadêmica internacional, acerca dos processos erosivos em áreas de falésias. Isso permitiu evidenciar a curva crescente de trabalhos publicados desde 1993 a 2023, o que reverbera a importância de estudos sobre esses processos que, diante dessas alterações, repercutem sobre a dinâmica do espaço costeiro e a população, desencadeando transtornos e constituindo áreas de risco.

Introduction/purpose: This article presents a new approach to determining the dynamic characteristics of the automatic firing system of gas-operated automatic guns. Methods: Based on the real structure of the automatic firing system of gas-operated automatic weapons, a 3D model of the gun is simulated using Solidworks software, and the dynamic characteristics of the automatic firing system are calculated on Solidworks Motion software. Results: The obtained simulation results include displacement and velocity of the breech platform over time; the force exerted by the hammer on the bolt carrier over time; and impact force of the bolt carrier and gun body over time. These results are compared with data obtained from experiments to verify the mathematical model. The cycle of a shot according to test results is 0.0846 s and the firing rate error between theoretical and experimental results is 2.82%. Conclusion: Research content allows users to visually evaluate the working process of all parts of the automatic firing system. The results of this research can be applied to calculations for automatic firing systems of different automatic guns. This is an important scientific basis for improving and upgrading existing automatic weapons and serving the process of designing and manufacturing new types of automatic weapons in the future.

Como es sabido, 1391 significó un antes y un después para la mayor parte de las aljamas judías hispanas. Las consecuencias de los asaltos a las juderías fueron múltiples y de largo alcance, siendo las principales de ellas la muerte, el destierro y la conversión. Como consecuencia de ello, la Andalucía Bética se convirtió en una de las regiones de la corona de Castilla con un mayor número de judeoconversos, circunstancia que podría explicar los acontecimientos que se desarrollaron durante el siglo XV y que, entre otras cosas, determinaría a los Reyes Católicos a establecer la Inquisición en Sevilla, lo que tuvo lugar en 1480, con lo que, una vez más, la ciudad del Guadalquivir se situaba a la vanguardia de todo lo relacionado con la minoría hebrea. Trataremos de sintetizar las muchas e importantes consecuencias que el establecimiento de la Inquisición tuvo para los conversos sevillanos, para lo que, en primer lugar, nos referiremos a la dinámica histórica de la instauración de la Inquisición, durante el reinado de los Reyes Católicos, en la que Sevilla y sus conversos tuvieron un gran protagonismo, para seguidamente tratar de resumir sus principales consecuencias, tales como la muerte o el encarcelamiento, el destierro, la desarticulación familiar o la inhabilitación de cargos y oficios, con la consiguiente confiscación de bienes, todo lo cual marcó el destino trágico de un buen número de conversos y de sus familias. Como contrapartida, muchos de estos conversos judaizantes, que fueron perseguidos por la Inquisición, consiguieron rehabilitarse y recuperar sus vidas y fortunas, mientras que otros tantos conversos, tenidos por cristianos ortodoxos, nunca fueron acusados ante la Inquisición. Tratar de aproximarnos a esta compleja y poliédrica realidad, es nuestro principal objetivo en las páginas que siguen.

Conservation offsets promise cost‐effective conservation of biodiversity, especially under economic and environmental change, because they represent a more flexible approach to biodiversity conservation, allowing for the economic development of ecologically valuable land provided that this development is offset by restoration of previously developed areas. The level of flexibility is determined by the trading rules. Lax rules allow for more flexibility, which promises cost savings, but will likely lead to unintended loss of biodiversity. I analyzed the trade‐off between economic costs and ecological benefits (biodiversity conservation) in biodiversity offsetting with an ecological‐economic model that considered the three main types of offset flexibility: spatial, temporal, and ecosystem type. I sought to examine the influence of ecological and economic conditions on offset flexibility trade‐offs. Large variation in the conservation costs and small costs of habitat restoration strongly increased trading activity and reduced the ecological benefit. The ecological benefit was most sensitive to spatial flexibility when a short range of ecological interaction was considered. At a large interaction range, spatial flexibility delivered large cost savings without overly reducing the ecological benefit. Risks and time lags associated with habitat restoration favored an offsetting scheme in which credits are awarded with the initiation of restoration projects rather than their successful completion—given appropriate offsetting multipliers were chosen. Altogether, under scarce resources, the level of flexibility in an offsetting scheme should be chosen by carefully balancing ecological benefits and economic costs. [ABSTRACT FROM AUTHOR]

El currículo ecuatoriano promueve el uso de simulaciones para la enseñanza de Física. En esta investigación se diseña una estrategia didáctica para el uso de GeoGebra en el aprendizaje de los conceptos de movimiento y fuerza para los estudiantes de Bachillerato General Unificado. En este estudio cualitativo-exploratorio se aplicó un test y una encuesta a una muestra de estudiantes de este nivel, así como una entrevista al docente de Física para diagnosticar la disponibilidad de recursos y las dificultades en el aprendizaje de Física. Se encontró que los estudiantes perciben a la asignatura como difícil de aprender, poseen deficiencias en sus habilidades matemáticas, frecuentemente no dominan los contenidos previos y no comprenden la relación entre las variables implicadas en los fenómenos físicos. Posteriormente se desarrolló una estrategia didáctica que incluye simulaciones para que los estudiantes comprendan significativamente los fenómenos relacionados con estos contenidos.

The Force Concept Inventory is a test to determine the level of conceptual knowledge of students about mechanical physics and to evaluate the effectiveness of different teaching strategies on the conceptual component of learning. The test was applied with the purpose of knowing the level of conceptualization of the students who study the subject of Physics in a basic and medium educational institution. The results of the pre-test gave to know the students' level of conceptualization and offered information for the elaboration of workshops based on real physical situations to elaborate force diagrams. The results of the post-test allowed estimating Hake's learning gain and showed evidence about the students' conceptual evolution and information to develop future teaching activities about Newton's laws.

Presentaremos en esta ocasión una reseña sobre historia, situación y prospectiva del Grupo de Investigación/Extensión del Programa Análisis Institucional y Pedagogías Alternativas (PAIPA) y del Servicio de Intervención y Asesoramiento Institucional (SIAI) de la Unidad Académica Río Gallegos –UNPA; con el propósito de dar cuenta de las características de su dinámica y el acontecer dramático de los equipos en distintos momentos de su trayectoria.

The visualization of information and knowledge enables an understanding of the hidden meaning of the information that is not directly apprehensible from the data, processes and phenomena, facilitating the obtaining and communication of relevant research results. However, the application of its methods and techniques in the training of social science professionals is still insufficient, which has limited their research performance. The objective of the article was to base a theoretical model of the dynamics of training in information and knowledge visualization for the communication of research results in the social sciences. The research methods used were content analysis of relevant theoretical sources and systemic modeling with a holistic-configurational approach. The main result of the modeling is to have revealed as a regularity the dialectical relationship that is expressed between the selection of information and scientific knowledge to communicate and the systematization of its optimal visualization. It is concluded that this regularity is a necessary and essential condition for the development of the visualization of information and knowledge competence for the communication of research results in the social sciences.

Este trabajo tiene por propósito central el identificar las relaciones entre los factores de la dinámica familiar en personas de 50 años y más en parentesco con migrantes de Durango, México. Teniendo como base un estudio cuantitativo, no experimental, transversal y correlacional con hombres y mujeres en etapa de pre-envejecimiento y envejecidas, se conformó una muestra no probabilística intencional – de red con 629 participantes, quienes aportaron información en un cuestionario autoadministrado. Para el tratamiento de los datos se realizó un análisis factorial, construyendo 4 etiquetas: afectividad, apoyos sociales, conflicto/violencia e interacción. Los resultados indican que la afectividad y la interacción tienen una relación positiva moderada, mientras que los apoyos sociales y el conflicto/ violencia tienen una asociación negativa. Asimismo, variables como el tipo de parentesco, el grupo de edad, el cuidado y las remesas juegan un papel central para aproximarse a los entornos familiares. Por lo tanto, existe la necesidad de seguir explorando las situaciones complejas a las que se enfrentan los envejecientes en contextos de alta migración y visibilizar los retos pendientes en materia de trabajo social y política social para con este colectivo social.

Effective conservation requires understanding species' abundance patterns and demographic rates across space and time. Ideally, such knowledge should be available for whole communities because variation in species' dynamics can elucidate factors leading to biodiversity losses. However, collecting data to simultaneously estimate abundance and demographic rates of communities of species is often prohibitively time intensive and expensive. We developed a multispecies dynamic N‐occupancy model to estimate unbiased, community‐wide relative abundance and demographic rates. In this model, detection–nondetection data (e.g., repeated presence–absence surveys) are used to estimate species‐ and community‐level parameters and the effects of environmental factors. To validate our model, we conducted a simulation study to determine how and when such an approach can be valuable and found that our multispecies model outperformed comparable single‐species models in estimating abundance and demographic rates in many cases. Using data from a network of camera traps across tropical equatorial Africa, we then used our model to evaluate the statuses and trends of a forest‐dwelling antelope community. We estimated relative abundance, rates of recruitment (i.e., reproduction and immigration), and apparent survival probabilities for each species' local population. The antelope community was fairly stable (although 17% of populations [species–park combinations] declined over the study period). Variation in apparent survival was linked more closely to differences among national parks than to individual species' life histories. The multispecies dynamic N‐occupancy model requires only detection–nondetection data to evaluate the population dynamics of multiple sympatric species and can thus be a valuable tool for examining the reasons behind recent biodiversity loss.

The practical aspects of the dynamical parameter identification method of an ABB IRB140 robot (off-line calibration procedure) are presented, such as identifiability, reduction to base parameters, inclusion of the measurements noise model and their influence on estimation uncertainty, scaling, and prior knowledge incorporation. A remarkable result is the calculation of the trajectories that provide a set of persistently excitatory signals of the dynamics in order to improve the estimation. The signals preprocessing is another relevant aspect since, to reduce the effect of noise, the excitation is limited in bandwidth and the derivatives of the joint positions are calculated in the transformed space.

Este estudio tuvo como objetivo caracterizar el comportamiento de la costa y la erosión de la playa de Moín, en el Caribe Sur de Costa Rica. También tuvo como objetivo comprender la relación entre los procesos de acreción y erosión con la construcción de la terminal de contenedores APM. La metodología se basó en el mapeo de la costa entre 2010 y 2019, la adquisición de perfiles topográficos de la playa y el análisis granulométrico de las arenas, estacionalmente entre 2016 y 2017. Los resultados muestran un comportamiento dinámico entre 2010 y 2015, con variaciones en la longitud en respuesta a los cambios en las condiciones del mar, típicos de una playa oceánica. Entre 2017 y 2019, hubo un aumento de sedimentos en el sector noroeste de la playa, cerca de la terminal; con erosión posterior en el sector sureste, evidenciado por un retroceso de la línea costera de aproximadamente 15 metros y una reducción en el volumen emergido de sedimentos, causando la caída de árboles y la exposición de raíces.

Clasificar el movimiento humano se ha convertido en una necesidad tecnológica, en donde para definir la posición de un sujeto requiere identificar el recorrido de las extremidades y el tronco del cuerpo, y tener la capacidad de diferenciar esta posición respecto a otros sujetos o movimientos, generándose la necesidad tener datos y algoritmos que faciliten su clasificación. Es así, como en este trabajo, se evalúa la capacidad discriminante de datos de captura de movimiento en rehabilitación física, donde la posición de los sujetos es adquirida con el Kinect de Microsoft y marcadores ópticos, y atributos del movimiento generados con el marco de Frenet Serret, evaluando su capacidad discriminante con los algoritmos máquinas de soporte vectorial, redes neuronales y k vecinos más cercanos. Los resultados presentan porcentajes de acierto del 93.5% en la clasificación con datos obtenidos del Kinect, y un éxito del 100% para los movimientos con marcadores ópticos.

In this paper, I intend to discuss two models of judge proposed by François Ost: Jupiter and Hermes. According to Ost, Jupiter represents both Kelsen’s positivism and iusnaturalism. In what follows, I intend to prove that Ost’s characterization of Kelsen is partial. It is restricted to consider the static character of his theory omitting Kelsen’s legal dynamics. Besides, I will show the limits of Ost’s equation between positivism and iusnaturalism. In regard to Hermes, Ost claims that it has a democratic character due to formal aspects of Law and its process and to freedom of speech. However, I intend to prove that Hermes is strongly anti-democratic: the ruling es immediate and based on a moral intuition. This implies that it is unilateral, partial, and antidemocratic. Finally, I will contrast Hermes with Hegel’s concept of mediation. I do not intend to fully discuss Hegel’s political and legal philosophy, but I do intend to show that Hegel’s concept of mediation can provide an answer to Hermes’ deficiencies.

Este artículo analiza y evalúa una serie de dinámicas pedagógicas utilizadas en el Taller de Proyectos (Design Studio), en las enseñanzas de Grado de Diseño de Interior. Cada dinámica se diseña artísticamente, casi como si fuera una acción, para crear un ‘evento pedagógico’ que enseña a diseñar a través de la experiencia, tratando de trasmitir el contenido del Taller de Proyectos de un modo vivencial. Las dinámicas son inspiradoras hasta tal punto que pueden ser trasladables a cualquier disciplina. No obstante, el artículo incluye un soporte teórico específico: una discusión y un contraste comparativo con diferentes modelos del método pedagógico del Taller de Proyectos (Design Studio). Este artículo constituye la segunda parte de un artículo anterior: Dynamics-aktion[1]. Por ello, continúa describiendo dinámicas no incluidas en el anterior y avanza hacia una conclusión valorativa del contenido de los dos artículos. A su vez, ambos artículos complementan un artículo previo, el cual describía el planteamiento completo de un curso de Proyectos de Diseño de Interior: #eindakoa# (lo que hemos hecho) Un MÉTODO pedagógico del MÉTODO de Proyectos de Diseño de Interior.[2] [1] DOI: https://doi.org/10.7203/eari.12.17633 [2] DOI: https://doi.org/10.7203/eari.10.13763

La enseñanza-aprendizaje de la táctica es el proceso orientado al desarrollo de los conocimientos y habilidades para el combate, el comportamiento táctico sintetiza la forma de evidenciar el nivel de desarrollo alcanzado. Las inconsistencias teóricas y la insuficiente comprensión acerca del desarrollo de la táctica han generado insuficiencias, en particular, en la dinámica del proceso referido, así como en el comportamiento táctico de los taekwondistas de la categoría 11 -12 años. El presente artículo explica cómo se articulan y coordinan los componentes de la dinámica referida. Los métodos empleados fueron el análisis-síntesis, la modelación y el sistémico estructural funcional.

There is significant variation in antibody levels among patients exposed to SARS-CoV-2 or following vaccination. However, the quantity of antibodies at which one is considered protected, or for how long they can provide it, is unclear. In general, it is presumed that antibodies wane over time, more notably around the 6 months mark following the second dose. Our study aimed to observe these processes dynamically, by tracking the variation of IgG anti-Spike protein antibody levels in a population of volunteers at the Cantacuzino National Military Medical Institute for Research and Development. A total of 1338 samples from 524 participants, either symptomatic or asymptomatic, were collected before vaccination and at predetermined intervals after the first and second dose, over a 10-month period (December 2020 - October 2021). The samples were tested via enzyme-linked immunosorbent assay (ELISA) method, using commercial Anti-SARS-CoV-2 QuantiVac ELISA (IgG) quantitative test kits - Euroimmun (Medizinische Labordiagnostika). The majority of participants were vaccinated with BNT162b2 (Pfizer BioNTech) (474 participants - 90.46%). Samples were grouped according to the length of time between exposure (infection or vaccination) and testing, along with exposure type (vaccinated, vaccinated with prior infection, unvaccinated with prior infection). The data suggests that vaccinated participants, with or without a history of infection, held higher antibody levels compared to unvaccinated participants with a history of infection. A decline in antibody levels over time in all test groups was noted, though less steep among participants with a history of infection. [ABSTRACT FROM AUTHOR]

The teaching learning of tactics is oriented towards the formation of combat skills, in such a way, tactical behavior configures the mode of action that shows the level reached in this process. The referred skills are conceptualized from two perspectives: technical-tactical skills and tactical skills. The first lacks a holistic vision that integrates the physical, theoretical and psychological components; on the contrary, the second one highlights their interaction and recognizes some singularities of the tactic. However, the proposals for didactic actions from the development of the class are insufficient. Consequently, the training of tactical skills in Taekwondo has been limited; in fact, the tactical behavior of taekwondo players in the 11-12 year category exhibits limitations. This article proposes a didactic strategy for the treatment of tactics, based on elements of class dynamics. All the specialists consulted agreed on the relevance, applicability and social relevance of the proposal, which was evidenced in the values obtained by consensus through the cut-off points. The methods used were observation, analysis-synthesis, functional structural systemic, and consultation with specialists through a survey, empirical frequency distribution and cut-off points.

A robotic exoskeleton is an electromechanical device that can be worn by a person to increase its physical capacity, to assist locomotion or for gait rehabilitation processes. In the case of rehabilitation exoskeletons, the control system is required to be smooth and capable to match accurately with the patients’ evolution in order to optimize the eciency of their recovery, this implies the design of robust and precise controllers. In this paper, kinematic analysis, dynamic analysis and control system evaluation for ALICE rehabilitation exoskeleton is presented. Among the control techniques used are: the PD controller, adaptive PD, and the sliding mode controller. In addition, a stability analysis using the Lyapunov criterion is performed. To test the performance of the controllers, gait data obtained by the ONCE School of Physiotherapy in Madrid, which correspond to healthy people and people with multiple sclerosis, are used. MATLAB as simulation software and programming language is used.

Faced with the challenges imposed by the knowledge society, universities are committed to perfecting their work, both in the role that corresponds to teachers and students, which necessarily affects the quality of the training process for future professionals. The teaching-learning process is a process of direction of cognitive activity, expressed in learning, stimulated through the use of various resources that enhance the formation of stable reasons for its realization. In this case, an assessment of its essence is made, when considering the logic of its execution, the dynamics and the requirements for the stimulation of learning, based on the analysis of the work of different authors as a review and the use of theoretical methods, in order to contribute essential ideas that aim to contribute to the teaching and research preparation of teachers.

The concepts of occupational accident, and especially of professional illness, do not express concrete realities that are self-evident by name alone. The recognition of a "link" between work and illnesses has always been a much more gradual, more problematic process than that linking work and accidents in the strict sense of the word. In this article, we focus on the risks of becoming ill "on the occasion of or as a consequence of work". In a review of a sample group of around 1,000 court sentences between 1936 and 1983, we analyse the influence of structural inertias, highlighting in particular the signs of change, in line with the evolution of legislation and the way it was interpreted by the courts. The changing social context is also taken into account. As a normalized expression of social facts (the occupational health risks to which workers are exposed), the concept of "occupational hazard" is still very much under construction, in a process that is contradictory and far from linear.

Entropy measurements are an accessible tool to perform irregularity and uncertainty measurements present in time series. In signal processing, the Multiscale Permutation Entropy is recently presented as a methodology of characterization capable of measuring randomness and nonlinear dynamics existing in non-stationary time series, such as mechanical vibration signals. In this article, the Multiscale Permutation Entropy is combined with diverse feature selection techniques and multiple classifiers based on machine learning aiming to detect different operative states in an internal combustion engine. The best combination is selected from the evaluation of parameters like precision and computational time. Finally, the proposed methodology is established as an effective tool to diagnose failures in bearing systems with a high precision rate and a reduced calculation time. [ABSTRACT FROM AUTHOR]

When discussing quantum ontology, the debate has recently focused on comparing and contrasting wavefunction realism and its rivals. Among them one finds the primitive ontology approach, which is often conflated with the local beables program. In this paper I wish to clarify what I take to be the distinction between the notion of primitive ontology and the one of local beable. I argue that the primitive ontology is the local beable which allows for a dynamical, constructive explanation which preserves symmetries. [ABSTRACT FROM AUTHOR]

Resultados para aplicação da metodologia proposta são apresentados. A atividade foi desenvolvida na escola pública Dr. Santiago Dantas, localizada em Rio Branco-AC, com alunos do 3º ano do Ensino Médio, como parte integradora do projeto de extensão “Ciência na escola: Experimentação e Teoria”, que reúne durante uma semana no período do contraturno, aulas diferenciadas sobre física, química e biologia, desenvolvida por graduandos de Licenciatura das respectivas áreas. Esta ação representa uma das frentes de trabalho desenvolvida por bolsista de física do Programa Institucional de Iniciação à Docência (PIBID/Física) da Universidade Federal do Acre (UFAC). Os resultados mostram que os estudantes durante a aula e sobretudo na dinâmica, aprimoram o raciocínio lógico e o trabalho em equipe, além de reconhecerem que a física torna-se mais atrativa com tais ações. Verificou-se ainda que o uso do recurso proposto representa uma nova estratégia de ensino com grande aceitação e participação ativa por parte dos alunos.

Se investiga la dinámica del proceso de esterificación del ácido acético con metanol para la obtención de acetato de metilo, considerando el flujo de ácido acético desde un tanque cónico y el de metanol desde un tanque cilíndrico. En ambos casos, los flujos y la temperatura son variables. Los reactivos se descargan a un reactor esférico, donde se realiza la reacción de esterificación, las condiciones de volumen, temperatura y concentración son dependientes del tiempo. La constante específica de velocidad de reacción y la constante de equilibrio en función a la temperatura son datos reportados de literatura especializada. Para el modelamiento de este proceso se establece los balances de masa global, balance de masa por cada componente y los balances de energía en cada uno de los tanques lo cual conduce a la obtención de un sistema de catorce ecuaciones diferenciales ordinarias resueltas a través del software Polymath. Se obtienen los perfiles de temperatura y concentración en cada uno de los tanques y el reactor, asimismo, la altura y volumen de fluido en cada uno delos tanques. Los resultados dependen de las condiciones de alimentación de la mezcla reaccionante y de las condiciones mantenidas en el reactor.

Las desigualdades regionales y la innovación, como determinante del desarrollo, han estado presentes en la literatura sobre sistemas regionales de innovación (SRI), pero los aportes empíricos generalmente no han abordado estos fenómenos. El objetivo de este artículo es analizar las desigualdades entre los SRI en Argentina durante el periodo 2003-2013 mediante la elaboración de un índice sintético y diferentes subíndices. Los resultados muestran la persistencia de profundas heterogeneidades entre los SRI, lo que lleva a repensar las políticas públicas en dicho periodo y, a futuro, demandar intervenciones que atiendan las desigualdades territoriales.

Las plantaciones de palma aceitera requieren de manejo y control de variables que permitan garantizar un exitoso proceso de cosecha, en el que se garantice altos niveles de eficacia de las plantaciones y eficiencia en el uso de los recursos asignados. Diseñamos un modelo de simulación del proceso de polinización entomófila asistida en plantaciones de palmas aceiteras para la proyección de escenarios futuros de producción. Realizamos un estudio no experimental, de tipo descriptivo propositivo para generar el modelo de simulación aplicando la metodología de dinámica de sistemas. Trabajamos con una muestra de 72 palmicultores, cuyas parcelas están ubicadas en la de Región Loreto - Perú, a quienes aplicamos un instrumento para conocer el total de hectáreas, número de parcelas, área, año de siembra, hectáreas en producción, con una polinización natural, racimos por planta, kilos por planta y porcentaje de inflorescencia polinizada y sin polinizar. El resultado fue que planificamos escenarios futuros de producción en las plantaciones de palma aceitera basándose en la simulación del proceso de polinización entomófila asistida utilizando el modelo construido desde el año 2019 hasta el 2030. Concluimos que a través del modelo de simulación creado aplicando la metodología de dinámica de sistema es posible predecir escenarios futuros de producción en las plantaciones de palma aceitera del Shanusi

En el artículo se estudia la evolución de una de las economías regionales que se desarrollan al Noreste de la Provincia de Santa Fe: la del arroz. Lo hace en el marco de los desequilibrios territoriales que caracterizan a esta Provincia que se reflejan en desigualdades productivas, económicas y sociales entre el Norte y el Sur provincial. Con un enfoque histórico, pretende analizar el desarrollo y la evolución de la producción arrocera en Santa Fe, su molienda y exportaciones desde la implementación del modelo de Convertibilidad en 1990, hasta el presente, indagando sobre el impacto de los cambios de escenario macroeconómico sobre el desarrollo de esta producción, su estado actual y perspectivas.
