Abstract - The teaching-learning methodology in the engineering education system is moving from a teacher-centric model to a student-centric model. The student-centered learning model is a method of learning or teaching that keeps the learner at the center. Outcome-Based Education (OBE) is an education model that focuses on the student-centric model which equips the students with the desired knowledge, skill, attitude, and behavior at the time of graduation. The National Board of Accreditation (NBA) is an accrediting body in India and its norms ensure that professional programs adopt OBE, and as an initiative, it has defined twelve Program Outcomes (POs). These POs are to be demonstrated by the graduates upon completion of the program. Professional programs curriculum will play a vital role in the attainment of POs. Therefore, the curriculum has to be designed in such a way that all the POs need to be addressed. The majority of the courses in the curriculum address the first five POs and are called disciplinary outcomes. The rest seven POs i.e PO6 to PO12 are generally named as professional outcomes and to address these POs, the department has to put in additional effort. In this paper, aCurriculum Compliance Improvement Model (CCIM) is proposed that performs the gap analysis of the existing curriculum and aid to enhance the curriculum compliance for PO attainment by suggesting suitable actions. These actions can be implemented by fine-tuning the curriculum design and teaching-learning process which will provide an environment for the students to attain all the graduate attributes (POs), the proposed model is illustrated through a case study. Overall, the model proposed is useful for the Tier-1 institutions that are keen on their students attaining all the graduating attributes, and also, ensures to meet the objectives of the accreditation procedure. Keywords— Accreditation, Course Outcomes, Disciplinary Outcomes, Engineering education, Outcomes-Based Education, Program Outcomes, Gap Analysis, Curriculum Design.

Abstract : The present study aims to present, from the main characteristics of Education 4.0, its possibilities and applicability in industry 4.0. As a subsidy, an exploratory study was carried out through bibliographic research in the main research bases in order to obtain updated knowledge on the theme of Education 4.0 and Industry 4.0. The results denote the importance of the applicability of the main ideas of this form of education in the current and future moment, mainly because the current and future generations are very involved in the concepts of connectivity and hybrid learning. The limitations of this research reside in the fact that, as it is a new situation, which had to be adopted almost instantly, it needs to have a greater maturity and there is a need for further research and studies, mainly in the search for the best application of technologies in the educational field. The practical implications highlight that the use of technologies in education is a reality in which teachers and students should increasingly perceive themselves as immersed and open to new educational possibilities. The originality of the study lies in the fact that education aimed at the application of new technologies still has a wide field of research andmany areas still do not have the necessary depth regarding education 4.0. Keywords: Education 4.0; Industry 4.0; New educational technologies

Abstract : In various fields like automobiles, construction, etc., the structural analysis of each component or sub-system must be done to ensure its safe operation. The structural analysis of these components entails the determination of parameters like shear force, bending moment at different locations. Usually, such computations are cumbersome, and hence a simplified approach is adopted, that involves drawing shear force diagram (SFD) and bending moment diagram (BMD) for the components. These diagrams can be effectively utilized to determine the dimensions of the components, select the appropriate material for the structure etc. Also, by utilizing the values of maximum shear force and bending moments, the maximum deflection in a beam or other structure can be ascertained. However, the process of drawing these diagrams is cumbrous and involves a lot of meticulous effort and time, which sometime poses a challenge in the effective teaching and learning of these concepts.The current paper reports the development of computational tools using the excel VBA platform and its implementation in the pedagogy of an undergraduate solid mechanics classroom. The developed tools can be easily employed to instantaneously draw the SFD and BMD diagrams for the beam under a variety of loading conditions, facilitating the inference-based learning of cantilevers and beams. Two distinct tools were developed, one for drawing the SFD and BMD of both cantilever and simply supported beams, and another one to determine the deflection and slope in the same two beams. The tools reported in the current manuscript can be effectively utilized for teaching by the demonstration of parametric variations under various loading conditions, for improved comprehension of the concepts and self-learning as well as in real world engineering to get preliminary design guidelines. Upon the development of these computational tools, these have been introduced to undergraduate mechanical engineering class of a sizable population and student responses regarding the efficacy of such tools in aiding the learning process has been recorded through an anonymous feedback. The subsequent hypothesis testing and obtained p-values strongly justify the extreme usefulness of the tools, both as a teaching and learning strategy.

Abstract: Employability skills are the capabilities and qualities employers look for in candidates while assessing them for employment. In case of engineers, employers demand generic and technical skills from engineers ready to join industries. This paper aims to explore the perception of Indian employers on the issue of the employability skills of engineers. Specifically, it aims to determine whether the skill requirement of engineers will change or remain the same in the post-COVID 19 era. This study used the interview method of qualitative analysis in which 16 interviews of human resource managers of different multinational companies were conducted. The findings reveal a sudden and significant paradigm shift in the required set of employability skills for engineering professionals. Digital skills have dominated over other technical and generic skills in the list of employability skills that recruiters demand. The findings can be used to spread awareness among engineering graduates about the changing demands of the workplace. Secondly, higher education institutions can rethink and revise their curriculum to develop digital skills. Lastly, the use of in-depth interview method can help future researchers to develop questionnaires from the extensive data and replicate the research questions to understand the change in demand of employers.

Water shutoff in oil wells operated in naturally fractured reservoirs is one of the most complex types of geological and technical operations in the oil industry related to repair and insulation works, the success rate of which does not exceed 35–60 %. In order to increase the efficiency of such operations, a set of sealing compositions based on the processing of natural materials, such as sand, peat, rice husk is proposed. Using the methods of mechanochemical activation, it was possible to dissolve sand in a low-concentrated alkali and obtain a sealing compound reinforced with undissolved sand particles by gelating the resulting sodium silicate. When combining mechanically activated sand and peat, a hybrid sealing material with the ultimate shear stress 27.7±1.2 Pa was obtained. The same approach made it possible to activate rice husks containing up to 20 % biogenic silicon dioxide and obtain a hybrid sealing material with the ultimate shear stress of 16.2 ± 0.6 Pa. This makes it possible to consider materials from natural and plant-renewable raw materials very promising for repair and insulation work.

Nowadays, the state level has set the task of forming a systematic approach to secondary resources management that were obtained from production waste, as well as increasing the efficiency of resource useage throughout the production life cycle. This is evidenced by the initiation and implementation of the sectoral program «Usage of secondary resources and secondary raw materials from waste in industrial production», supervised by the Ministry of Industry and Trade of the Russian Federation since November 2022, Decree of the President of the Russian Federation of November 4, 2020 No. 666 «On Reducing Greenhouse Gas Emissions», Strategy «Socio-Economic Development of the Russian Federation with Low Greenhouse Gas Emissions by 2050» approved by order of the Government of the Russian Federation of October 29, 2021 No. 3052-r and Federal Law of 02.07.2021  No. 296-FZ «On Limiting Greenhouse Gas Emissions» (entered into force 30.12.2021).

To achieve economic, social and environmental sustainability, it is necessary to interact between enterprises, universities and authorities in order to stimulates the application of the principles of circular economics. This article discusses the problem of utilization and use of associated petroleum gas, as well as analyzes the possibilities of applying the concept of industrial symbiosis both to reduce the produced resources and minimize the loss of materials during use. The relevance of this topic is justified by an increase in the volume of associated petroleum gas (APG) production and, accordingly, the damage caused to the environment due to its combustion. In addition, insufficient financial investment hinders the successful development of innovative economic schemes such as industrial symbiosis.

The methods of APG disposal and processing used at present were analyzed, the negative consequences of combustion, sanctions imposed by the state and restrictions on their application were investigated. According to the authors, an important problem is the lack of new technologies, as well as the low level of their technological readiness, which leads to the use of most APG as energy resources instead of its processing. The study briefly discusses the main methods of processing associated petroleum gas, their advantages and disadvantages, as well as possible recommended areas of APG use.

The effectiveness and feasibility of introducing the concept of industrial symbiosis in the oil industry is justified. As a result of the study, the authors of this article proposed the most optimal option for processing and further use of the obtained components, the probability and reality of the implementation of the described processing method is also described.
METHODOLOGICAL ASPECTS OF THE STUDY OF THE RATE CONSTANT OF THE REACTION OF HYDROCHLORIC ACID WITH CARBONATE FORMATION ROCK

Published: September 2023

Hydrochloric acid treatments are most widely used to intensify oil production from carbonate reservoirs. But despite a wealth of experience in the use of hydrochloric acid treatments, the results of treatments often do not reach the planned values of oil production growth. Efficiency of acid exposure depends on the depth of penetration of the hydrochloric acid solution into the thickness of the productive reservoir, which, in turn, is conditioned by the degree of reactive activity of the acid composition. It is important to achieve the creation of filtration channels in the zone remote from the borehole, which will lead to an improvement in the filtration characteristics of the bottomhole formation zone to the proper extent. Therefore, in order to achieve the best result when planning acid exposure, it is important to consider the geological and physical properties of the object to be treated and select the appropriate formulation of the acid composition.

The reaction rate constant is a parameter that allows you to take into account the compatibility of the acid composition and the geological and physical conditions of the productive reservoir. This parameter characterizes the rate of reaction between substances. However, a generally accepted method for studying the kinetic parameters of the reaction of acid compositions with carbonate formation rock has not yet been developed, which leads to low reproducibility of experimental results. The purpose of the research presented in the article is to develop a methodology for studying the kinetics of the reaction of hydrochloric acid with carbonate rock and to create a unified approach to determining the reaction rate constant, characterized by the greatest reproducibility of the results. The experimental part of the work was carried out in several stages, including the preparation of core material, the preparation of hydrochloric acid solution and its thermostating, and the further conducting of four series of studies at the PIK-OSG volumetric setup to determine the optimal acid-rock ratio, identify the optimal weight of the core material and establish the optimal coarseness of its grinding.

The obtained results of experiments on the study of methodological aspects of the study of the rate constant of the reaction of hydrochloric acid with carbonate rock showed that the experiments should be conducted in conditions of an excess of rock relative to acid, in this case the mass of the core sample and the coarseness of the grinding of the core material will not affect the error in determining the reaction rate constant.

Stroke is the leading cause of death in Korea. The demand for a multidisciplinary approach and transfer of patients between hospitals to receive higher-level treatment is increasing. However, there are many obstacles in selecting optimal hospitals for paramedics or stroke patients. This has led to a need for comprehensive stroke centers (CSC) capable of providing advanced and multidisciplinary care. Articles with information about guidelines, and other relevant clinical and research reports were investigated to establish the concept of certification for a CSC. Experts recommended by stroke-related societies gathered to form a consensus through public hearings, several meetings, and academic conferences. Herein, we aimed to write the policy statement for CSC certification. We described key elements of CSC in Korea. These areas include healthcare personnel with specific expertise in a number of specializations for stroke care, specific infrastructures and advanced diagnostic techniques including neuroimaging capabilities, surgical and endovascular techniques and neurocritical care for complex stroke care, and programmatic elements such as a stroke registry, education, and quality improvement activities. CSCs should have a comprehensive team that includes neurologists, neurosurgeons, vascular surgeons, neurointensivists, neuroradiologists, rehabilitation specialists who perform cutting edge diagnosis and treatment for two or more complex acute stroke patients simultaneously in an all-in-shop model without additional transfer to other hospitals.

The Influence of Language Contact on the Usages of xən35 in Duyun Dialect
Authors: Tang Shiyin
Published: September 2023

Duyun has been a multi-ethnic area since ancient times, and its grammar has been influenced by both Chinese and local minority languages. This paper is intended to compare the usages of the hen-family in Duyun dialect, Mandarin, and minority languages from the perspective of language contact, and to trace the origin of xən35 in Duyun dialect by examining the evolution of hen in Chinese. It is proposed that the prepositive usage of xən35 is a historical continuation of hen in Chinese during the Yuan, Ming, and Qing dynasties, while the postpositive usage of xən35 is influenced by the local minority languages. The distinctive usages of xən35 in Duyun dialect are due to language contact.

Anti-Locality and Covert Movement in Arabic
Authors: Helal Abdel-Rahman Hani Abu
Published: September 2023

This paper provides a new argument for the specifier-to-specifier anti-locality constraint from covert movement. The argument is based on an observed asymmetry behavior of the Quantifier Raising (QR) of the superlative morpheme in two superlative adjectives modifying relative clauses in Levantine Arabic (LA): the two superlative modifiers give rise to different paradigms of high and low interpretations. The paper shows that a configuration restricted by the specifier-to-specifier anti-locality constraint straightforwardly explains the asymmetry lending further evidence supporting this syntax-economy condition from covert movement. The data discussed in this paper follow from the authors’ native speaker intuitions. To replicate the judgements, five native speakers of Jordanian Arabic were consulted: three males and two females who are in their late twenties or late thirties. All consultants, including the author(s), are based in Eastern Amman; an urban area of the capital Amman of the Hashemite Kingdom of Jordan. It is worth mentioning that Jordanian Arabic is a dialect of Southern Levantine Arabic. It is one of the mutually intelligible varieties of Levantine Arabic that is spoken by the people of the Hashemite Kingdom of Jordan. The two dialects are used in daily conversational exchange along with the most official diglossia of Modern Standard Arabic used in official written documentation and mass media (See Ababneh et al., 2017; Fukara, 2022; Zyoud & Zyoud, 2022 and Abu Helal, 2021a) for more information).

Published: September 2023

This research aims to explain how critical literacy was practiced in an EFL reading class. In this reading class, students read and responded to a short story about bullying and friendship entitled Egghead. The data were generated from the classroom’s observations and interactions and students’ artifacts during the reading class. This research thoroughly examined 1) how critical literacy was employed in the reading classroom and 2) students’ engagement in the class. Using the four dimensions of critical literacy by Lewison et al. (2002), this research has figured out that critical literacy practices in the reading class are feasible to raise students’ awareness. Two significant findings are emphasized in this research. First is the positive outcomes during classroom discussions. Second, this approach can create an atmosphere that can motivate students’ enthusiasm and enjoyment. Both findings show that employing critical literacy allows students to verbalize their thoughts and opinions of their worldview, raising their awareness and understanding of social issues. However, as a role model, the teacher must engage students in a meaningful discussion while selecting and considering appropriate reading materials.

Published: September 2023

This research work sets out to explore the major distinctions between Arabic and Bangla—the languages with unidentical origins. Comparing and analyzing the various features of these two languages requires huge linguistic expertise in the respective fields as it is a most complicated job for anyone to accomplish. Arabic and Bangla are two of the leading languages of the world, specially in terms of their number of speakers and the growing demands. As Arabic and Bangla are from unalike families of languages, they differ a lot in the word class, grammar, pronunciation, usage and so forth. The sentence in Arabic is divided into two types: verbal i.e. V+S+C and nominal i.e. S+C; while the typical Bangla sentence pattern is inflexion-based i.e. S+C+V. Like any other vocalized languages, Bangla has eleven vowels, but Arabic has no such vowels since Arabic alphabet is considered an ‘abjad’ (i.e. ‘أبجدية’ /aːbʤadiah/) meaning a ‘consonantal alphabet’ and so the syllable is often formed without any vowels. Moreover, Arabic writing starts from right to left, whereas Bangla is from left to right. Despite all these differences, Arabic and Bangla have some similarities as well. For instance, they do not have any differences between the upper case and the lower case. Besides, Arabic and Bangla are phonetic and rhotic languages. Nevertheless, there are a few more minor differences between Arabic and Bangla. Hence, this paper is intended to provide the learners, users, as well as teachers of the two languages with some important facts and findings which are often faced in writing, speaking and translating.

MONÓLOGO COMO MODALIDAD DEL DISCURSO DEL PERSONAJE EN LA NARRACIÓN
Authors: Álamo Felices Francisco
Published: September 2023

La desaparición de la novela social y comprometida y de sus personajes más referenciales, como los denominados «históricos», «colectivos» o «arquetípicos», entre otras denominaciones, ha desarrollado en la narrativa contemporánea —como antítesis del realismo— un obsesivo y radical tratamiento del yo y de sus procesos internos de reflexión e introspección. El monólogo se va a convertir, pues, en una de las técnicas narrativas más utilizadas por los autores, como consecuencia de esta inmersión en la crisis de la identidad del sujeto contemporáneo. Este artículo aborda, desde esta prioridad del monólogo en la caracterización del personaje de las últimas décadas, su estatuto teórico, sus diferentes modalidades y clasificaciones y su tratamiento textual.

La homocisteína y la enfermedad cardiovascular
Authors: Laverde G. Diana Patricia
Published: September 2023

de Framingham reconoció la homocisteína (Hcy) como un posible factor de riesgo para enfermedad cardiovascular (ECV) y en el año 2003 lo declaró como factor de riesgo "emergente". La hiperhomocisteinemia se define como el aumento de los niveles plasmáticos de Hcy total (unida a proteínas más fracción libre), por encima de 15 μmol/L y se clasifica en tres niveles de severidad, moderado de 15-30 μmol/L, intermedio de 31-100 μmol/L y severo mayor de 100 μmol/L. La hiperhomocisteinemia puede producirse por una deficiencia enzimática en alguno de los pasos de su metabolismo, también se puede presentar por bajos niveles plasmáticosdel ácido fólico y las vitaminas B6 y/o B12. La insuficiencia renal puede ser otra causa, debido a que el riñón es la ruta para eliminar la Hcy del plasma. La suplementación dietaria con ácido fólico reduce lasconcentraciones de Hcy en sangre en un 25%, la suplementación con vitamina B12 en un 7%, mientras que la suplementación con vitamina B6 no tiene efecto en esta disminución. Un estilo de vida saludable, una dieta balanceada con un moderado consumo de café y alcohol y dejar de fumar, contribuye en la reducción de los niveles plasmáticos de Hcy.

Este artículo tiene como objetivo ofrecer una serie de criterios para demostrar las ventajas del municipio en la formulación y desarrollo de la política de seguridad alimentaria y nutricional. La exposición conduce a reflexionar sobre la ganancia de esta política pública en términos de efectividad, si se toman en cuenta los factores institucionales y físico-espaciales que ofrece este nivel territorial. Al evidenciar estas ventajas, se quiere significar que si el estado colombiano presenta un modelo político centrado en la sociedad, su manera de actuar será a través de alianzas con otros actores para producir resultados de interés colectivo como la seguridad alimentaria y nutricional. A través de los análisis de evaluación del gasto social, tanto del departamento como de la nación, se extraen conclusiones referentes a la bondad del nivel municipal como centro de gestión de políticas sociales.
Efecto de la actividad física sobre la ingestión de energía y nutrientes en mujeres jóvenes universitarias: un análisis bayesiano
Authors: Monterrey Gutiérrez Pedro Agustín , Cortés Sanabria Lilia Yadyra
Published: September 2023

Antecedentes: la actividad física es una de las acciones principales para disminuir la prevalencia de obesidad. El deporte de alto rendimiento incrementa el consumo de energía, pero no está establecido claramente qué sucede con las personas cuya actividad física se dirigida a mejorar su estado de salud. Objetivo: determinar si la actividad física produce cambios en los niveles de ingesta de energía y nutrientes para mejorar el estado de salud. Materiales y métodos: dos grupos de estudio formados por mujeres, uno que cumplía con los niveles recomendados de actividad física para la salud y otro que no. El análisis estadístico se realizó a partir de un modelo de efectos mezclados. Resultados: la actividad física para mejorar el estado de salud no incrementó las ingestas de energía y proteínas, aunque sí las de grasas, carbohidratos y colesterol. El consumo de fibra semodificó pero fue bajo. Conclusiones: la disminución en la ingestión calórica pudiera determinar un balance energético negativo que favorecería la pérdida de grasa corporal, manteniendo la masa muscular. Las personas más activas físicamente descuidaron la calidad de la dieta. Los patrones de variabilidad observados correspondieron a poblaciones con dietas variadas, no monótonas.

Se analiza el concepto de calidad en la educación desde dos dimensiones, la político-cultural- económica y social y la pedagógicacurricular y didáctica. Se identifican las normas colombianas que introducen la acreditación y los estándares de calidad en la educación superior, centrando la atención en la gestión curricular y en la ética. Se demuestra la preocupación de la acreditación por el control haciendo pensar que las normas, los procesos técnicos y la estandarización de procesos ofrecen calidad; sin embargo, este ensayo deja ver cómo las metas son simples cuando no se tienen referentes de interpretación, cuando no se aplican adecuadamente las metodologías de investigación, cuando los actores profesores, docentes directivos y los estudiantes siguen estando alejados de los procesos de cambio; también se expresa que a quienes les corresponde sistematizar los procesos, algunos no lo hacen con ética, maquillando los informes o simplemente no entendiendo el sentido de los cambios. En este ensayo se ha querido demostrar, que la intervención a las IES en razón de la acreditación para el mejoramiento de su calidad, no puede hacerse, al margen de una auténtica gestión curricular y de un compromiso ético; en donde haya posibilidad de comparar lo que había antes de la acreditación con lo que se encuentra después, que es necesaria una línea de base, una medida de la situación inicial, que permita calcular el avance de las transformaciones a partir del red iseño de los objetos (PEI, Plan de Formación, Rediseños de los Micro-Currículos, etc.) y el cambio de las acciones de los distintos actores, profesores, directivos docentes y estudiantes, (desde los nuevos paradigmas pedagógicos, curriculares, didácticos, de gestión, de evaluación e investigación), para darnos cuenta de si lo que estamos haciendo desde la acreditación es un simple rediseño o una transformación curricular.
Anemia ferropriva: ¿alguna solución?
Authors: Figueroa Pedraza Dixis , Cabral de Lira Pedro I.
Published: September 2023

Debido a la importancia del conocimiento sobre lo que representa la anemia como problema de salud pública, se realizó una revisión bibliográfica actualizada que muestra la realidad actual y las posibilidades reales de prevención y combate, proponiendo enfoques que pueden ser innovadores. El hierro es un mineral esencial para el organismo humano, cuya deficiencia es causa de anemia ferropénica que constituye el desorden nutricional más común en el mundo y de mayor magnitud en Brasil. La anemia por deficiencia de hierro, que afecta fundamentalmente a las mujeres en edad fértil, embarazadas y niños pequeños, es ocasionada no solamente por una ingesta deficiente de hierro dietético, sino que existen otros factores, como la biodisponibilidad, el tipo de hierro, su utilización durante la vida y las pérdidas y situaciones físicas y socio-económicas que también son importantes y que deben ser considerados a la hora de establecer las estrategias e instrumentos para su prevención y control. Así se conseguirán mejoras importantes desde el punto de vista biológico, social, de desarrollo y económico en los individuos y/o poblaciones afectadas. Dichas estrategias e instrumentos deben basarse en el estudio de las particularidades y tener como planteamiento básico mejorar la diversidad de la dieta y como planteamientos complementarios la fortificación de alimentos, la suplementación con preparados farmacéuticos y las medidas y leyes en materia de salud publica para abordar factores ambientales críticos.
La magia de la mirada durante la asesoría nutricional
Authors: Romo Aliste María Eugenia
Published: September 2023

Cada vez que hables con una persona, mírale a los ojos... La mirada, o movimientos oculares, provee información de los procesos internos que siente, ve o escucha el individuo, y es señalada como un elemento comunicacional a tener en cuenta, al establecer un diálogo. En respuesta a estos procesos internos, cuando las personas visualizan, desenfocan la mirada y la dirigen directamente el frente o miran arriba, a la derecha o a la izquierda. Cuando una persona habla interiormente, consigo misma, es probable que mire hacia abajo y a la izquierda. Cuando percibe sensaciones, suele mirar hacia abajo y a la derecha. El conocimiento del significado de la mirada o movimientos oculares, le permitirá al nutricionista encontrar respuestas que complementen las expresadas corporal y verbalmente por el cliente o paciente durante la asesoría nutricional y de esta forma, como profesional podrá corregir o entregar nuevos conocimientos alimentario nutricionales, evaluar los avances que ha tenido su interlocutor y optimizar el tiempo. En consecuencia, la atención consciente a los movimientos oculares puede ser utilizada como una herramienta comunicacional durante la asesoría nutricional y en cualquier otro evento en el que el nutricionista dietista deba o tenga que establecer un diálogo.
Densitometría Un método de referencia en composición corporal
Authors: Martínez López Elkin
Published: September 2023

La Densitometría ha sido considerada por largo tiempo como método de referencia para validar otros métodos de composición corporal, gracias a su alta precisión y a la racionalidad de su ejecución. El procedimiento se centra en medir el peso hidrostático y el volumen residual pulmonar en los individuos. Se describe el soporte conceptual de este procedimiento en una secuencia deductiva y se explican los detalles técnicos del método. En vista de su importancia como método estandar, se justifica una mejor comprensión de su lógica operativa y tal vez su adecuada implementación en centros académicos y de investigación.
El hierro como factor de riesgo cardiovascular
Authors: Agudelo Ochoa Gloria María
Published: September 2023

La enfermedad cardiovascular (ECV) constituye una de las principales causas de morbimortalidad en países desarrollados. Los factores de riesgo clásicos explican sólo entre la mitad y dos tercios de las variaciones en la extensión anatómica de la ateroesclerosis y el riesgo de ECV. El estado de los depósitos de hierro corporal emerge como uno de los factores de riesgo no clásicos, dentro de los nuevos posibles factores implicados. El presente artículo tiene como objetivo realizar una revisión de los datos epidemiológicos que apoyan o rechazan la hipótesis de la relación entre los depósitos de hierro y el riesgo de ECV. Para lo anterior se realizó una amplia revisión de resultados de diferentes investigaciones publicadas en los últimos 20 años. Se incluyeron estudios prospectivos, casos y controles y las más recientes publicaciones que mantienen la controversia sobre el tema. Se concluye que las evidencias que relacionan el estado nutricional del hierro con la ECV son escasas e inconsistentes y no justifican cambios en los programas de fortificación de alimentos o tratamientos médicos, especialmente por los beneficios de asegurar un adecuado consumo de hierro durante períodos críticos de crecimiento y embarazo. De todas formas se requiere de evidencias fuertes y consistentes antes de rechazar definitivamente la hipótesis de que grandes depósitos de hierro incrementan la incidencia de ECV ó muerte por infarto al miocardio.
Conferencia. El chocolate y su relación con la salud cardiovascular

El chocolate es un alimento consumido por personas de todas las edades en un gran número de países del mundo. Por su aporte calórico y por su contenido de grasa, ha ocupado una posición controvertida en el mundo de los alimentos. El grano de cacao contiene 35% de ácido oléico, 35% de ácido esteárico, 25% de ácido palmítico y 5% de ácido linoléico; además contiene 11.5% de proteína, 9.5% de ácidos orgánicos y aromas, 9% de celulosa, 6% de ácidos tánicos y color, 5%de agua, 2.6% de sales minerales, 1.2% de teobromina, 1.0% de azúcares, 0.2% de cafeína (Rossner S. 1997). Los efectos biológicos del consumo de chocolate están dados por todos sus componentes, los cuales difieren en gran medida de los efectos de sus moléculas aisladas. En varias investigaciones, se ha demostrado que la grasa del chocolate, aportada en forma de ácido esteárico y ácido oleico principalmente (70%), no afecta el colesterol total, ni las lipoproteínas LDL, y que el alto contenido de polifenoles del cacao está asociado con importantes beneficios para la salud por su efecto antioxidante, lo cual ha sido relacionado con la prevención de la enfermedad cardiovascular.
