Published: August 2024

Quiero agradecer, en primer lugar, al Dr. Gustavo Cuartas por su generosidad al invitarme a compartir con ustedes este día de celebración de la profesión en latinoamérica. Inicialmente pensamos que un tema de punta como el de las vacas locas podría ser el más apropiado para traer a este escenario, pero luego llegamos a un acuerdo fundamental: que aprovechemos la celebración para introducir discursos que parece que no caben en los afanes y urgencias de la cotidianidad. Fue así como llegamos al título propuesto, y siento gran placer en compartir algunas anécdotas para llegar finalmente a proponer, en serio, algunos cambios que creo urgentes para la educación del ser humano de hoy y que requieren cambios mayores no sólo en los currículos, sino, y en primer lugar, en los profesores y en los directivos.

Authors: Gómez G. Leonardo F. , Hernández Carlos , Restrepo Luis F. , Orozco P. Sonia C.
Published: August 2024

Resumen
La endoscopia digestiva superior (EDS) es un método diagnóstico muy utilizado actualmente en la medicina de pequeños animales. El procedimiento requiere anestésicos y la selección de los mismos es crucial. Este estudio comparó los efectos de tres inductores etomidato, ketamina y propofol, en su capacidad para facilitar o hacer más difícil el paso del endoscopio hasta el duodeno. También se determinó, con cuál de estos agentes inductores se utilizaba menos tiempo para realizar la técnica, y se estableció el protocolo que permite una recuperación más rápida. Se encontró que ninguno de los inductores utilizados dificultó significativamente el acceso al estómago ni el paso por el mismo. Con el etomidato se pasó por el estómago en un tiempo menor pero la diferencia no fue significativa, como tampoco hubo diferencia en el tiempo necesario para atravesar el píloro; sin embargo, desde el punto de vista clínico este paso si fue menos fácil con la ketamina. En cuanto a la recuperación anestésica el propofol permitió un tiempo de recuperación menor (p > 0.05). Se concluye que los tres agentes tuvieron un comportamiento similar desde el punto de vista estadístico, pero clínicamente el etomidato fue mejor.
Summary
Upper digestive endoscopy (EDS) is a currently used diagnostic method in small animal practice. The procedure requires anesthetics which selection is crucial. This study compared the effects of three of them: etomidate, ketamine and propofol, regarding capacity to facilitate the passage of the endoscope until (or down to) to the duodenum. It was also determined which of these inducers contribute the best to perform the technique in a shorter time, and which one of the protocols leads to a faster recovery. The results indicate that none of the inducers make significantly more difficult the access to the stomach, nor the passage through this organ, although with etomidato the time needed was shorter. There were no differences either in time or difficulty to go through the pylorus. Nevertheless, from the clinical point of view ketamine made this step more difficult. For recovery, propofol did present a significant shorter period (p > 0.05). It is concluded that the three studied agents show a similar statistical profile, but from the clinical point of view etomidato behaves better.

Authors: Hernández Carlos , Gaviria Alejandro , Restrepo Rodrigo
Published: August 2024

Resumen
Un paciente canino de raza Pastor alemán se trató satisfactoriamente por una gastroenteritis infecciosa, sin embargo se detectó que el perro regurgitaba con frecuencia. En el esofagograma con bario se observó una gran dilatación esofágica en el tercio proximal del esófago torácico y en la esofagoscopia se confirmó la presencia de un divertículo esofágico. El tratamiento quirúrgico incluyó la toracotomía lateral con resección quirúrgica del divertículo, colocación de un tubo de drenaje torácico usando una válvula de Heimlich. También fue colocado un tubo de gastrostomía para alimentación enteral. El paciente se recuperó satisfactoriamente de la cirugía, sin presentar ninguna complicación. Los divertículos esofágicos son de presentación poco frecuente en los perros y su ruptura puede llevar a condiciones graves como mediastinitis y la muerte del paciente. La resección quirúrgica es el tratamiento de elección sólo en los divertículos que manifiesten síntomas clínicos que alteren la calidad de vida los pacientes.
Summary
A German Shepard dog was attended presenting an infectious gastroenteritis. Once the dog responded to treatment, it was noticed that the patient regurgitated frequently. In the barium esophagogram it was detected a big esophageal dilatation in the proximal third of the thoracic esophagus, and the upper endoscopy confirmed an esophageal diverticulum. The surgical intervention included a lateral thoracotomy with esophageal diverticulum resection, thoracic tube drainage with a Heimlich valve, and a gastrostomy tube placement for enteral nutrition. The patient recovered satisfactory without any complication. Esophageal diverticulum is infrequent in dogs and its rupture can lead to critical conditions as mediastinitis and death. Surgical resection is essential in the treatment of esophageal diverticulum in cases were clinical symptoms are important.
Polimorfismos en la longitud de fragmentos amplificados (AFLP´s) a partir de muestras de sangre almacenadas en tarjetas FTA® para la especie Cavia porcellus Lin. (Rodentia: Caviidae)
Authors: Burgos Paz William , Rosero Galindo Carol , Cárdenas Henao Heiber , Solarte Carlos
Published: August 2024

Resumen
Una manera eficaz de establecer el grado de variabilidad entre y dentro de poblaciones, es a través del análisis de polimorfismos de ADN con marcadores moleculares como los AFLP's. En este artículo se presenta una metodología que combina la utilización de tarjetas de FTA® (Whatman Bioscience, Cambridge) para colección y conservación de muestras de sangre, con los procedimientos de extracción de ADN y obtención de marcadores AFLP´s, aspectos sobre los cuales no existen antecedentes para la especie Cavia porcellus. Se utilizaron muestras de ADN procedentes de tres poblaciones, dos criollas y una mejorada genéticamente obtenida a partir de un pie de cría procedente del Perú y sometida a selección en Colombia durante varias generaciones. Todos los animales procedieron de la Granja "Botana", propiedad de la Universidad de Nariño, Pasto-Colombia. Para la detección de polimorfismos en la longitud de los fragmentos (AFLP's) se utilizaron uno, tres y cinco discos FTA® de 1.2 mm, cada disco con aproximadamente 25 ng de ADN. Los ensayos indicaron que los mejores productos de amplificación, para la visualización de AFLP's, se obtuvieron de muestras con tres discos de FTA® por individuo, lo que sugiere que con esta metodología, 75 ng de ADN por animal son suficientes para detectar polimorfismos de alta calidad en el genoma de Cavia porcellus. Se recomienda el uso de las tarjetas de FTA® para el estudio genético de poblaciones de Cavia porcellus, con las modificaciones metodológicas descritas en este artículo para marcadores AFLP´s.
Summary
A methodology that includes the use of FTA® (Whatman Bioscience, Cambridge) to collect and store animals' blood samples and the procedures to extract and to get AFLP markers is presented in this paper. A review of the literature indicates that there are no reports concerning both aspects for the Cavia porcellus case. To reach our goal blood samples of three populations - Two native ones and other genetically improved- were obtained through heart puncture. This blood was stored in the FTA cards in order to extract, purify, amplify and analyze their DNA forms. All of the animals came from "Botana" farm of the Universidad de Nariño, located in Pasto, Colombia. For amplifying the AFLP one, three and five 1.2 mm FTA disks of approximately 75 ng of DNA per disk where used. The tests indicated that the best products to amplify and to visualize the AFLP where those ones obtained from samples of three FTA disks per animal. This suggests that 75 ng of DNA per animal is enough to generate AFLP of high quality in the Cavia porcellus' genome. We recommend the use of FTA cards to carry out genetic analyses in the Cavia porcellus, including the methodology modifications presented in this paper.

El papel de la insulina en la regulación de la síntesis de proteínas lácteas en bovinos
Authors: Correa Cardona Héctor Jairo , Echeverri R. Nancy P.
Published: August 2024

Summary
In spite of the nutritional and industrial importance of milk proteins the mechanisms that control their synthesis and concentration still are not completely understood. Among the different hormones that participate in the mammary gland metabolism, insulin has received higher attention due to its close relationship with the energetic and protein metabolism in dairy cows and to its marked effect on the production and concentration of milk proteins. There are at least three mechanisms by which this hormone seems to contribute to increase in the synthesis and concentration of milk protein that are reviewed in this paper: nutrient distribution to mammary gland, regulation of gene expression of caseins and the rate of initiation of protein synthesis at post-transcriptional level.

Pre-disaster and response activities in disaster management: Insights from an experts’ survey and document analysis
Authors:   Oklahoma State University, Rodríguez-Coca Diana Mercedes , Espejo-Díaz Julián Alberto ,   Universidad de La Sabana, Guerrero William Javier ,   Universidad de La Sabana
Published: August 2024

Emergencies, disasters, and catastrophes require urgent attention from communities and governments to both prevent and mitigate their impacts. Disaster management is a field of academic research and practical application that encompasses a comprehensive range of activities divided into three main phases: pre-disaster (preparedness and mitigation), response, and recovery. The pre-disaster phase includes efforts such as risk assessments as well as emergency planning and preparedness, while the response phase includes activities such as aid delivery. In this paper, the authors analyze how pre-disaster and response activities impact societies differently when facing various kinds of catastrophes. Specifically, scientific articles and official disaster management reports were reviewed to develop a document analysis that focuses on the pre-disaster and response operations performed in four different types of catastrophes: nuclear power plant accidents, volcanic eruptions, hurricanes, and landslides with distinct features around the world. Next, the study presents an experts’ survey and compares the findings with the document analysis. The results show that adequate and sufficient efforts in pre-disaster activities have a more significant impact on preserving lives and reducing the economic impact of catastrophes than response activities. Nevertheless, both pre-disaster and response activities are essential in confronting catastrophes and should be carried out. Operations managers working in humanitarian logistics should direct efforts and resources toward developing effective pre-disaster strategies in areas vulnerable to these risks.

Published: August 2024

Background. In the conditions of war, the effective state budget distribution and use are essential to ensure the defense of the state, support the economy and the proper standard of society living, and the Accounting Chamber, as the supreme audit institution, has a significant potential to influence these processes. The object of the study is the activity of the Accounting Chamber, the recommendations provided as a result of the audits, and their impact on the distribution and use of the state budget. Methods. The recommendations are systematized and classified into groups depending on their areas. The structure of the provided and implemented recommendations in terms of objects, types of measures and areas was determined by the statistical method. Indicators of the recommendation implementation by areas and the average number of recommendations by types of measures were compared. Results. The mechanisms of the direct and indirect influence of the Accounting Chamber on the distribution and use of the state budget are shown. 540 recommendations based on the results of audits in 2022, carried out under difficult conditions of martial law, were analyzed, of which 66% were derived from performance audits. The areas of influence on the state budget are (in order of decreasing number of recommendations): regulatory and legal acts and internal documents; improving the efficiency of the audit object; quality of planning and forecasting; budget expenditures; use of state property and land; internal control and audit of auditee; financial, budgetary and other forms of reporting; income of the state budget; data, registers, information systems and their interaction; personnel management, appointment of responsible persons; accounting; state enterprises; deficit, financing and public debt. In total, 26% of the recommendations have been implemented, which indicates an unused impact potential. Conclusions. Ways to enhance the influence of the Accounting Chamber through improving the quality of reports and recommendations, speeding up and automating work processes, implementing international standards, improving the legal framework and interaction with stakeholders are proposed.
SEARCH FOR MULTIMEDIA INFORMATION BASED ON NEURAL NETWORKS

Published: August 2024

The article considers approaches to the use of neural networks in multimedia information retrieval. The develop ment of methods for multimedia information retrieval is necessary due to the large amount of such information. Tradi tional methods of multimedia information retrieval have a high speed of data processing, but low accuracy due to the inability of semantic search. The use of neural networks allows for semantic search, which increases its accuracy and completeness. Approaches to the use of neural networks at the stages of indexing and retrieval of multimedia infor mation are considered. With the help of a neural network, a multimedia file is analyzed and classified. The result of classifying a file is used to create its textual description - an annotation that is compared to the search query to deter mine relevance. There are many ready-made classification networks that can be used to speed up the process of creat ing a multimedia search system, but it is not possible to create a neural network to classify all real-world objects, so multiple neural networks should be used. Neural networks are also use to build feature vectors for a media file and a search query. Similarity functions, such as cosine of similarity, are applied to constructed vectors to determine the semantic similarity of a query and a media file. In this case, the search query can be both in text form and in the form of the appropriate format of the desired media file. This approach allows to build an optimal neural network for a specific task. Neural networks are used to compare the constructed annotation of a file and a query, which increases the accu racy and completeness of the search, compared to traditional methods, due to the ability of neural networks to take into account the semantic meaning of the text.

Background. The increase in malicious activity in the information and cyberspace poses a challenge to the leaders of enterprises (organizations) and the leaders of companies with additional tasks and benefits to protect their assets. The loss of assets, for example, financial or technological, can make it impossible for the company to achieve its basic function - to generate profits. Methods. The work used the information security risk analysis method. Results. Сreation and promotion of current information security systems. Organizations spend significant financial resources on the development and operation of technology protection, create various structural subdivisions, such as the assessment and provision of a similar level and information security of the enterprise (company). At the same time, there is a real risk of the current situation if malicious and more current technologies are able to rig the system to protect the company and cause irrevocable costs, both financial and reputational. Сonclusions. One of the main directions of this problem is the creation of an information security management system (ISMS), which is a warehouse management system for an organization (company) and is assessed without bears the risks of creating, implementing, operating, operational monitoring, review, support and thorough information security organizations (enterprises). The ISMS includes the organizational structure of the organization (company), its policies, nutritional planning, monitoring of labor costs, promotion of daily practices, control and support of resource processes. As a best practice, to assess the level of information security of an organization, it is recommended to use a different approach that is based on the capabilities of process maturity models. The extracted results can be used to thoroughly and optimize the created information security system of the organization (company). There are currently a wide range of information security maturity assessment models available to organizations based on similar principles. In this case, it is realistic to select such models to be limited, first and foremost through a weak connection to the characteristics of specific organizations. The work examines models of the maturity of processes, their structure and the ability to evolve in the course of assessing the level of information security.
Autoria feminina
Authors: De Oliveira Dileane Fagundes , Alós Anselmo Peres
Published: August 2024

a reflexão a respeito da autoria feminina remete ao processo histórico que produz a escrita de autoria feminina, como um fenômeno cultural, bem como às relações de poder no confronto de interesses que ocorreram na sociedade e que influenciaram seus significados. É preciso refletir sobre o passado para que se possa compreender o presente. Por muito tempo, as mulheres foram representadas pelo discurso masculino na literatura, na filosofia, na biologia, na história e demais áreas do saber, e essas representações ganharam status de verdade a respeito do gênero. Mas algumas dessas mulheres, fugindo do enclausuramento doméstico que lhes era imposto, buscaram inserir-se no âmbito social, que era, por excelência, o espaço reservado ao homem. O presente ensaio tem como objetivo refletir sobre a emersão da autoria feminina na literatura brasileira e, para tanto, coloca a crítica literária feminista (produzida tanto no Brasil quanto no exterior) com um rol de obras literárias consideradas pioneiras, de autoria de mulheres e publicadas ao longo do século XIX.

Using appropriate teaching methods to improve students’ learning results is important in universities. This study points out measures to improve the effectiveness of group discussion methods in teaching and learning the History of the Communist Party of Vietnam curriculum at Hanoi National University of Education. The quantitative paradigm was used, through which an experimental design was applied to the experimental group. Convenience sampling was used to collect 383 students in the experimental group and 187 students in the control group. The data was collected by using pre- and post-test examinations, and a validated questionnaire. The results showed that the group discussion method improved students' interests and learning outcomes. The lecturer had the main role in controlling the group discussion while the students were still the center of the group discussion. The students were encouraged and properly directed to participate in group discussions by dividing the class into small groups (8-10 students/group) discussing the same topic; informing students in advance about the discussion topic; correcting the students’ presentation of their opinions in class; helping the students form ideas during the discussion; and bringing out discussion topics close to the students' preferred choices

Kant talks about a transcendentally necessary mind and, less often, about an intelligible mind. The two characterizations of the mind have similarities. However, there are also important differences. The properties grouped under ‘transcendental’ are cognitive, those grouped under ‘intelligible’ are conative. The properties grouped under ‘transcendental’ are nearly all congenial to cognitive science. Many grouped under ‘intelligible are not.

Se analizó la información disponible de 16 factores ambientales de 73 localidades correspondientes al Cono Sur de América (Brasil 2, Uruguay 1, Argentina 70), teniendo en cuenta además las especies presentes y las áreas de endemismo de Simuliidae. La información se ordenó en dos matrices de datos, una con 73 localidades y 19 variables y la otra con las localidades y las 39 especies halladas, las que fueron sometidas a un análisis multivariado similar: Análisis de Agrupamiento y A.C.P.; los resultados fueron complementarios basados en los datos biogeográficos y de habitat. La información fue volcada en mapas, resultando de la primera matriz 2 grandes grupos con 3 subgrupos cada uno y un pequeño tercer conjunto sin agrupar: el grupo A corresponde a la fauna tropical y subtropical que incluye el norte de Argentina, sudeste de Brasil y el oeste de Uruguay, el grupo B corresponde a la fauna austral y occidental, incluyendo Patagonia, Cuyo y las sierras Subandinas. Con la segunda matriz aparecen tres grupos bien diferenciados y un cuarto no agrupado: A en el nordeste y el área subtropical, B sobre el trópico occidental en el área de Yungas, que se extiende hacia el sur por el centro y el oeste sobre el área del Monte hasta el norte de Patagonia y sur de Pampas, y un grupo C sobre el suroeste en el área Subantártica. En síntesis se evidencia la presencia de dos faunas bien diferenciadas: una tropical y otra subantártica. La comparación entre los caracteres ecológicos y el de áreas de endemismo de especies de Simulium muestran una gran concordancia. Se hizo un análisis de cada uno de los factores ambientales y la distribución de las especies tratando de inferir la influencia de cada factor en la presencia de las especies. Con base en el análisis de resultados obtenidos se expone la hipótesis sobre una posible expansión de especies de importancia sanitaria en el área estudiada.

INTRAGENERIC RELATIONSHIPS OF MAINLAND ELEUTHERODACTYLUS II. A REVIEW OF THE ELEUTHERODACTYLUS SULCATUS GROUP
Authors: Lynch John D.
Published: August 2024

Nine species are recognized in the Eleutherodactylus sulcatus group, including one species described as new. Frogs of this species group are distributed in cloud forests of Colombia and Ecuador as well as at lower elevations in the western Amazon basin (Brasil, Colombia, Ecuador, and Peru) and along the frontier between Colombia and Panama. A cladistic analysis (based on cranial morphology) results in a nearly fully resolved cladogram. The cloud forest species form a clade within the species group. Ali pairs of sister species are allopatric but some biogeographic paralogy suggests that initial andean diversification of this clade antedates the present Andean geography.

Un total de 70 lances de pesca fueron hechos en diferentes sitios del ecosistema, en cada uno de los cuales un boliche prototipo usado normalmente en las capturas comerciales fue encerrado por un boliche experimental cuya área interna fue cubierta por cinco lances con atarraya. Los resultados mostraron que la especie más vulnerable a la captura del boliche es el Macabí (Elops saurus), mientras que la Lisa (Mugil incilis) es la menos retenida. Se encontró también que la fracción de peces retenida por un boliche, no está asociada con la biomasa disponible que encierra el utensilio y más bien parece estar relacionada con factores como la efectividad en la maniobra de pesca y el comportamiento de los peces al encuentro con la red. Se recomienda aplicar un factor de retención de 0.47 y 0.24 en peso y número respectivamente, para estimar la capturabilidad del boliche.

Authors: Gorkiy Artem S. , Fomin Mihail V.
Published: August 2024

This article is devoted to a detailed study of the interaction between innovation systems and innovation processes. The application of the regional-national innovation system (RIS) model has been studied, and it has been revealed that it is a targeted strategy aimed at accelerating economic growth through the introduction of scientific developments into the production cycle. The importance of including distinctive regional characteristics in analytical models for a more adequate representation of the real innovative and competitive capabilities of the regions under consideration is substantiated. The need for modification of methodologies for the analysis of regional innovation systems (RIS), adapted to the specifics of local development and external integration, is emphasized. It has been established that an adequate assessment of the innovative capacities and positions of regions in the global economic space is hampered by the presence of divergence in classification standards. The need to include a new type of RIS in the classification is shown, which adequately reflects the initial stages of systems development in the context of unique Russian regional features. An analysis of the dynamics of interaction between key actors within these systems has been obtained, contributing to a deep understanding of the mechanisms of transfer of innovative knowledge among actors, providing tools for managing the development of regions, identifying the drivers of their competitive advantages and focusing on market participants.

Estimating the effect of climate on agriculture with the productive value of agricultural land
Authors:   Banco de México, Arellano-González Jesús
Published: August 2024

Objective: the Ricardian model, in which market land values are modeled as a function of climate, has been estimated extensively in the context of developing countries where its core assumptions are likely to fail due to missing or incomplete markets. This article proposes a new measure of land valuation that better reflects agricultural productivity in such contexts: the Productive Value of Agricultural Land (PVAL). Methodology: a three-step empirical strategy is applied to data from a survey of Mexican rural households. The first step is the estimation of an agricultural production function. In the second step, parameter estimates are used to calculate PVAL. In the third step, PVAL is used as the dependent variable in a Ricardian regression. Results: suggests that PVAL increases with more precipitation and decreases with by extreme heat. When the Ricardian regression is estimated using market land values, the positive effect of precipitation is underestimated and the effect of extreme heat on land productivity is null. Limitations: omitted variables bias could still influence the Ricardian estimates obtained using PVAL. Originality: a novel version of the Ricardian model is estimated, one that does not rely on market values of land. Conclusions: failing to account for the market setting of agricultural producers, particularly in developing countries, may lead to an underestimation of the effects of climate change in agricultural productivity.
Regulation of burst dynamics in the neuron-glial network with synaptic plasticity
Authors:   National Research Lobachevsky State University of Nizhny Novgorod, Stasenko Sergey
Published: August 2024

The purpose of this study is to develop and investigate a model of astrocytic regulation of burst dynamics of a spiking neural network with synaptic plasticity in inhibitory synapses. Methods. The “integrate and firing” model was used as a neuron model. To describe the dynamics of synaptic connections, a conductance-dependent synapse model with corresponding characteristic relaxation times for excitatory and inhibitory synapses was used. At the same time, inhibitory synaptic plasticity, described by the Vogel model, was used in the dynamics of inhibitory synapses between excitatory and inhibitory neurons. At the same time, the dynamics of excitatory synapses was regulated by the mean-field model of gliotransmitter concentration. Results. A model for the regulation of burst dynamics in a neuron-glial network with inhibitory synaptic plasticity was developed and studied. The main dynamic modes of neuronal activity were obtained in the absence of regulation, in the presence of only synaptic plasticity, and in the presence of also astrocytic regulation of synaptic transmission. A study was conducted of the influence of astrocytic modulation on the frequency of burst activity of the neural network. Conclusion. The study showed the possibility of controlling the burst activity of a spiking neural network by taking into account inhibitory synaptic plasticity for inhibitory synapses between inhibitory and excitatory neurons, as well as astrocytic modulation of excitatory synapses. Astrocytic modulation of synaptic transmission may act as an additional mechanism for maintaining homeostasis in the neural network beyond synaptic transmission, which exists on a faster time scale.

Machine-Learning Optimization of Energy Efficiency in Microwave Applicators with Plasma
Authors: Williams Camille E. , Murphy Ethan K. , Yakovlev Vadim
Published: August 2024

With a widening range of applications of microwave plasma in processing technologies, there is a demand of computer-aided design of efficient and controllable applicators containing microwave plasma. The use of modern computational tools here is limited due to a principal uncertainty in data on the plasma medium for electromagnetic simulations. In this paper, based on simplified characterization of microwave plasma, we propose to embed a model of an applicator with plasma in a machine-learning optimization procedure aiming to maximize energy efficiency of the system. To demonstrate functionality of the procedure featuring the dynamic training of the decomposed RBF network, we use a model of a conventional cylindrical applicator with a coaxial quartz vessel containing plasma. The model is built in the FDTD simulator QuickWave. For a neutral gas chosen, the procedure finds the geometry of the applicator and the plasma frequency satisfying the optimization goal.
