O puerpério é o período que se inicia após o desprendimento da placenta no parto e perdura até o retorno dos órgãos reprodutivos à situação pré-gestacional (cerca de 6 a 8 semanas). É um momento crucial para a saúde da mãe e do recém-nascido, frequentemente influenciado por condições socioeconômicas, educacionais e familiares. A pesquisa identificou práticas maternas durante esse período e promoveu o autocuidado e o conhecimento em um ambulatório-escola de Porto Velho, RO. A abordagem reforçou a importância de um atendimento humanizado e individualizado. Como parte do projeto, foi elaborada uma cartilha com informações práticas sobre autocuidado, que foi distribuída pelas redes sociais e às participantes da pesquisa. Além disso, objetivou-se realizar coleta de dados por meio de um estudo de campo transversal, utilizando questionários para identificar necessidades e práticas, buscando compreender as lacunas de conhecimento e contribuir para a capacitação de profissionais de saúde e para o aprimoramento do atendimento materno no período puerperal, infelizmente essa segunda parte da metodologia teve sua aplicabilidade comprometida devido o momento de pandemia de Covid-19 vivenciado durante o estudo.

OBJECTIVE: To describe the participatory management process in the development of a prioritization instrument for the School Health Program.
METHOD: This is a quantitative, cross-sectional and evaluative study, focused on improvements in the management of the School Health Program. An instrument was developed to prioritize managerial aspects, based on criteria of magnitude, priority and potential for participation. A participatory methodology was used, developed through consensus workshops with local managers, in a municipality in the Midwest of Brazil, between July 2021 and June 2023. The data were analyzed using descriptive statistics.
RESULTS: Elaboration of a matrix of priorities, considering the potential participation of the actors involved. The areas led by the health sector showed the greatest potential for participation, including priorities such as vaccination, obesity prevention, articulation of actions, coping with vulnerabilities, longitudinal care, local diagnosis, operational capacity of health units, and information management. In turn, components of the educational context, such as the local diagnosis and the operational capacity of the schools, showed less potential for participation.
CONCLUSIONS: The health sector demonstrated greater potential for participation compared to the educational sector. The process stimulated a more effective integration among local managers to classify emerging demands and define managerial priorities. The group's engagement in the collective construction of the prioritization instrument suggests the need to include participatory strategies that enable the exchange of experiences and good intersectoral practices, improving monitoring and evaluation in key areas. This process allows for horizontality, promotes collaborative work in response to territorial vulnerabilities, strengthens the operational capacity of institutions and information management. It also contributes to longitudinal care and a more accurate local diagnosis, which can increase the potential for participation of all sectors involved, an essential factor for health promotion in this context.

Oysters, bivalve mollusks, live predominantly in coastal regions and are valued for their high nutritional and culinary value. However, the ability of these mollusks to filter large volumes of water makes them susceptible to the bioaccumulation of pathogenic microorganisms, such as Escherichia coli and Salmonella. These contaminants pose a significant risk to public health, particularly due to the frequent consumption of raw oysters. The objective of this study was to analyze the presence of Salmonella spp and Escherichia coli in oyster samples marketed in the state of Pará, Brazil. There were 23 oyster samples, collected in 6 municipalities in the State of Pará.  Being 03 samples, from oyster growers' cooperatives and 20 samples collected from street vendors on beaches located on the coast of Pará. For the detection of Salmonella spp, the ISO 6579:2002 method was used, while the analysis of Escherichia coli followed the Embrapa protocol. The analyses revealed the presence of Salmonella spp. and Escherichia coli in 100% of the samples, regardless of the origin (cooperatives or street vendors). The contamination of oysters highlights failures in management and marketing. Our findings highlight the need for strict controls in the production chain to ensure the food safety of oyster consumers.

This study is aimed at exploring the knowledge, attitude, and practice (KAPs) concerning chicken coccidiosis and to examine the usage of anticoccidials among poultry farmers in Kwara State, Nigeria. Information accessing the KAPs of chicken coccidiosis and its control was collected from one hundred and twenty-three poultry farmers using a semi-structured questionnaire. More number of farmers (121/123; 98.37%) had knowledge about chicken coccidiosis, with 16.26% of them documenting that it is caused by a protozoan. Higher number of the farmers believed chicken coccidiosis is economically important, preventable and treatable. More number of farmers (n = 106, 86.18%) had previously used anticoccidials in their farm compared to those that had not 17 (13.82%). The thiamine analogue alone of anticoccidial was the most used drug (n = 27, 25.47%; 95% CI = 18.14 – 34.52) used by farmers. The frequency of anticoccidial drug usage by farmers decreased as the number of drugs being used increased. Data from this study will assist the government and other relevant stakeholders in identifying areas where farmers in Kwara State need to improve their knowledge, attitude, and practice concerning chicken coccidiosis for more effective disease management and improved productivity.

Una “épica académica” en la puerta del sur argentino
Authors: Campetella Luciano
Published: December 2024

A finales de la década de 1960 y principios de la de 1970, en el contexto de auge de las ideas desarrollistas y dependentistas, se despliega en el Departamento de Economía de la Universidad Nacional del Sur –UNS– (Bahía Blanca) un interesante proceso de renovación curricular que dio origen al que se considera el primer plan heterodoxo de enseñanza de la economía en el país. El artículo reconstruye ese proceso aten­diendo a la gestación del nuevo plan, el análisis del documento curricular, la síntesis de los aportes de algunos de los economistas del Plan al debate de aquellos años y su articulación final con el proyecto de la izquierda peronista en la UNS (Orbe, 2008).
El Estado empresario en el sector del litio en Argentina
Authors: Fuentes Pablo
Published: December 2024

El litio es un recurso natural estratégico y un mineral crítico clave para las industrias de la transición energética y la economía del futuro. En ese sentido, está adquiriendo creciente relevancia geopolítica y econó­mica. Argentina es el segundo mayor poseedor de recursos de litio y el cuarto productor a nivel mundial. En el presente trabajo se analiza el rol empresario y emprendedor del Estado Nacional para insertarse estratégica­mente en la cadena de valor de este recurso, a través de las iniciativas de YPF Tecnología S.A. (Y-TEC) y de YPF Litio S.A., entre los años 2013 y 2023. Ambas empresas funcionan bajo la órbita de la histórica petrolera nacional YPF y coinciden en generar un modelo de desarrollo integral en torno al litio, que abarque desde la extracción del recurso de los salares hasta su industrialización para la fabricación nacional de baterías de litio, buscando acoplar la infraestructura científico-tecnológica a la estructura productiva.

The purpose of this research is to evaluate the exports of primary and industrial products through the Principal Components Analysis in order to determine which are the ones that have a higher export quantity, not in economic terms, but in quantitative terms, and thus demonstrate that not because they have a higher annual or monthly income in money, they are the ones that are more exported to other countries from Ecuador and to potentiate them.
Un modelo de análisis de la imposición asimétrica a la exportación de bienes con elasticidad cruzada de oferta negativa y aplicación al estudio de la producción de soja y maíz en Argentina
Authors: González Germán , Schmidt Juliana
Published: December 2024

Los cultivos de soja y maíz son fundamentales en la estructura económica argentina porque dan origen a sus dos principales complejos exportadores y, por ende, representan una fuente significativa de recursos fiscales. Los cambios asimétricos en los incentivos al nivel del productor pueden tener repercusiones macroeconómicas relevantes. Este trabajo aborda teóricamente el estudio de los efectos esperados de la imposición asimétrica en las decisiones de los productores de dos bienes con elasticidad cruzada de oferta negativa. De la aplicación de dicho marco se llega a la conclusión de que los comportamientos del área cultivada de maiz y de la soja pueden ser teóricamente atribuibles al ensanchamiento en la brecha entre las alícuotas del impuesto a las exportaciones.
Simon, Schumpeter y las fronteras de la racionalidad
Authors: Pellegrini José Luis
Published: December 2024

En este artículo se analizan y comparan las concepciones de Simon y Schumpeter sobre la racionalidad, así como las posturas epistemológicas y metodológicas en que ambos autores fundamentan sus teorías, tomando como punto de partida un interrogante sugerido por la literatura acerca de si Schumpeter teorizó sobre racionalidad limitada en el mismo o similar sentido que Simon. Se concluye que dichas concepciones tienen muy poco en común, con diferencias sustanciales en cuanto al alcance y significado de la racionalidad dentro de sus teorías y divergencia en los aspectos epistemológicos y metodológicos.
Haciendo visible la bioeconomía
Authors: Coremberg Ariel
Published: December 2024

Diversos países de ALC hacen frente a los importantes desafíos que supone adecuar su “techo productivo” al potencial que ofrece la bioeconomía. La bioeconomía surge como un nuevo paradigma técnico-productivo que, a partir de recursos, procesos e insumos de base biológica, permite responder a la creciente demanda de alimentos, fibras y energía, a la vez que apoya la mitigación de los impactos negativos en el medio ambiente y los recursos naturales e impulsa los procesos de desarrollo local mediante la generación de nuevas fuentes de empleo e ingreso..La metodología propuesta permitió calcular el aporte de la bioeconomía a la producción, al comercio internacional (exportaciones) y al empleo de Uruguay en 2018. la bioeconomía en Uruguay generó valor agregado, lo que representa el 46.2% de la producción de bienes y mercancías y el 14.2% de todo el PIB
El sector económico que más contribuyó al PIB de la bioeconomía de Uruguay fue la industria manufacturera (54.2%), en la que sobresalen las industrias de alimentos y bebidas (35.2%) y de papel y madera (13%). Le siguen los sectores agrícolas generadores de biomasa (39.8%), el de agua y saneamiento (3%) y el de energía (3%).  La provisión de energía con base bio de origen forestal presenta una singular incidencia en el PIB, como quinto sector en importancia, un nivel similar al del sector de agua y saneamiento en el total de la cadena de valor de la bioeconomía. 
La participación de las exportaciones de la bioeconomía en el total de la producción bioeconómica fue altamente significativa (42.6%), lo que demuestra las ventajas dinámicas de la bioeconomía uruguaya en el comercio internacional. Los empleos generados por la bioeconomía uruguaya representaron el 17.7% de todos los producidos en la economía uruguaya. 
Tomando en cuenta la importante base de biomasa y una cada vez más desarrollada base tecnológica y de innovación en los países agrícolas, la elaboración de una Cuenta Satélite de Bioeconomía para los países de América Latina, que incorpore la inversión y actividades de innovación de la producción biobasado, además de los aspectos productivos, generación de empleo y comercio exterior aquí propuestos y analizados, constituye una herramienta fundamental no solo para analizar su estructura actual, sino también para identificar sus potencialidades a través de una política de desarrollo productivo que permita una mayor equidad regional y social.
La vigencia de Gramsci en el estudio de las organizaciones de representación de empresarios y propietarios rurales durante la redemocratización brasileña (1986-1991)
Authors: Fernandes Afonso
Published: December 2024

El presente trabajo tiene como objetivo discutir y presentar la forma en que el concepto de Estado ampliado de Antonio Gramsci constituye una herramienta teórico-metodológica para el estudio de las organizaciones de representación de empresarios y propietarios rurales entre 1986-1991. Tomando como foco la experiencia política del Frente Amplio de la Agropecuaria Brasilera (FAAB), objeto de estudio de la tesis de maestría del autor del presente artículo, se busca, en primer lugar, presentar los principales debates y conceptos que conforman la idea de Estado Ampliado en Gramsci, para luego señalar la manera como estos conceptos contribuyen al entendimiento de la experiencia política del llamado “Frente Amplio”. Así, puede concluirse que el referido instrumento teórico-metodológico contribuye con dos aspectos fundamentales. Además de permitir reflexionar sobre el objeto de estudio desde una perspectiva histórica, el concepto de Estado Ampliado permite comprender el significado de la experiencia política del FAAB como un importante aparato privado de hegemonía de las dinámicas fracciones agroindustriales de las clases dominantes agrarias brasileras durante la transición política de la dictadura militar al actual régimen político democrático-liberal.
Puntos preliminares para la resignificación de Marx en los estudios agrarios
Authors: Malagodi Edgard
Published: December 2024

Este ensayo pretende problematizar la noción de "marxismo" y su uso como idéntico a "pensamiento de Marx", específicamente en lo que se refiere a los estudios agrarios. En América Latina, el marxismo llegó relativamente tarde, después de la fundación del PCUS (Partido Comunista de la Unión Soviética) y de la creación de la Tercera Internacional Comunista en 1919. Los comunistas seguían aún la recepción de Marx por Karl Kautsky y se basaban en ella para establecer su política hacia los campesinos. A pesar de la resistencia de Mariátegui y otros, la concepción ortodoxa anticampesina predominó entre los partidos comunistas latinoamericanos, y sus ideólogos dominaron la escena intelectual de nuestros países. Por lo tanto, Marx - en particular textos de su última fase (Shanin)- debe ser recuperado. A pesar del uso generalizado de categorías nativas, un análisis de clase es posible y necesario para endosar el potencial de lucha de los campesinos.  El desafío actual es distanciarnos del "marxismo colonizado" que ha predominado hasta hoy en América Latina, lo que nos permite redescubrir la fuerza teórica del autor Marx para apoyar efectivamente a los movimientos campesinos en su lucha contra el violento proceso de saqueo que les impone el capital.

Climate variability is the main determinant of fluctuations in the productive and economic results of agriculture. Extreme events are expected to occur with greater frequency and intensity in the future. In this scenario, the effects of climate variability on agricultural production are of special interest.
This study analyzes the time series of yields at the county level of the main crops in the province of Buenos Aires, in the period 2000/01-2020/21. The trend and occurrence of extreme values ””of wheat, corn and soybean yields are identified. The frequencies of extreme values ””are related to the phases of the ENSO -El Niño-Southern Oscillation phenomenon, for each crop year.
Yields show significant positive trends in 78%, 46% and 30% of the counties for wheat, corn and soybean, respectively. There is a significant relationship between the frequencies of extreme yield values ””and the ENSO phases, this relationship being more important in summer crops. In particular, there is a relative frequency of extremely low or very low yields of 38 and 41%, in second consecutive La Niña crop years, for corn and soybean, respectively. While the frequencies of extremely low or very low yields in neutral or El Niño crop years are between 0% - 3%. Regarding the economic value of production, the differences between obtained vs. expected values, accumulated in the period, are positive values of +3285 and +872 million USD in “El Niño” years for the north and south regions, respectively, and negative values of -3387 and -388 million USD, in “La Niña” years for both regions, respectively.
The results provide evidence on the potential value of ENSO-based seasonal forecasts for agriculture. However, it is necessary to deepen the analysis of the effects of ENSO and other seasonal phenomena on yields. It is also necessary more information about the attitudes of the farmers in the Pampas and the different management practices that can be adjusted based on these forecasts.
Seguros agropecuarios basados en índices. Situación actual y visión de mercado de compañías aseguradores
Authors: Gastaldi Laura , Miguez Daniel
Published: December 2024

This paper presents the stage of development of agricultural index insurances in Argentina. Market penetration and five-year commercial prospects are analyzed using survey data from a sample of data provided of insurance companies. The majority of the parametric insurance approved by the National Insurance Superintendence in Argentina are designed to cover rainfall events for typical agricultural activities in the Pampas region, with little development for regional productions and/or areas outside the Pampas. One third of the insured companies currently offers this type of insurance, although sales level is null to medium. In the medium term, insurers perception of commercialization level of this type of insurance for crops and livestock is considered acceptable. Insurance companies agree on the importance of public-private programs to expand market, and the need of adequate climate data to improve the design and fit of these coverages to farmers.

Published: December 2024

The economic risk faced by a family walnut system that operates three hectares and has begun a process of technological reconversion consisting of the replacement of varieties and greater added value in the product sold, is quantified. The system is characterized in its structural and functional components (productive resources that it has and technology that it applies) and then, the economic results are estimated for the current values ””of price, yield and percentages of pulp and shell nuts sold. These variables are then randomized through triangular distributions, whose parameters (maximum, modal and minimum) are obtained from expert informants and market data. The distribution of results obtained (income in $/year) is contrasted with different points or critical levels and the frequency and intensity with which they are not covered is measured. From there, the risk typology of the system is defined.

The effects of drought have an impact on the productive sector in different regions, affecting vegetation, water availability and the consequences that this causes, so it is of interest to study its behavior in order to be able to carry out monitoring and early warnings. There are different proposed indices in the literature, some of which are obtained from meteorological data, and others from satellite images. The objective of the present work is to relate drought indices obtained with data from meteorological stations (Anomaly of Precipitation - AP, the Standardized Precipitation Index -SPI, the Standardized Precipitation and Evapotranspiration Index - SPEI), MODIS-Moderate Resolution Imaging Spectroradiometer  remote sensing indices (Normalized Drought Index- NDDI, Normalized Water Index- NDWI, Normalized Vegetation Index- NDVI, Enhanced Vegetation Index- EVI) and anomalies of the latter for the Dry Magellanic Steppe ecological area, considering the period 2000 - 2019. The results show that the SPI calculated at the 12-month scale correlates moderately with the NDWI anomaly, although both, like the NDDI, allow the detection of drought events in the period considered.

By converting biomass from agricultural and livestock waste into by-products such as biogas and biofertilizer, agricultural producers have the opportunity to turn costs into income. This increases domestic value added and employment in an environmentally friendly manner, while also increasing profitability and efficiency. Argentina's rural sector suffers from an annual limitation in the supply of diesel oil needed to process and market its production. It would be possible to enrich the biogas into biomethane and then transform it into fuel for long distance transportation. Its sale would contribute to the regional Argentina-Brazil-Chile transit, thus helping solve a structural problem, with the reduction of polluting emissions and saves in foreign currency.
In this work, we have designed an investment project for the production of liquefied biogas on a national scale, including the installation of pumps at 10 retail sites in Argentina, in line with intra-regional transit. By estimating the financial flows used to calculate the profitability, we determined the feasibility of the proposal, contributing to the environmental commitments previously made by Argentina.
Gestión de agua potable y saneamiento en Argentina. Medición inteligente del ODS6 para una gestión sostenible de los recursos hídricos
Authors: Aguirre Marcela
Published: December 2024

Water covers more than 70% of the Earth's surface, however, water suitable for human consumption ranges between 0.7 and 1% of the total. After two decades of the 21st century, with about 6 billion people inhabiting the planet, the United Nations (UN) studies show a serious water crisis, which will deepen without corrective actions to preserve this resource for future generations. Emerging technologies such as IOT and Artificial Intelligence provide an encouraging outlook for improvements in the care of water resources and the management of drinking water and sanitation (W&S). Measuring to improve management is a central aspect that contributes to the fulfillment of Millennium Development Goal number 6:  "Drinking Water and Sanitation" of the UN 2030 Agenda. There are currently several projects that contemplate specific indicators to make W&S management more efficient, such as the United for Smart Sustainable Cities and Communities (U4SSC) program, which provides an international platform and promotes partnerships between communities in pursuit of the ODSs.

La ganadería es la actividad predominante de las empresas agropecuarias del Partido de Bahía Blanca condicionada por su clima semiárido. La misma se encuentra expuesta a muy altos niveles de incertidumbre productiva y económica. El objetivo de este trabajo fue analizar y valorar las decisiones estratégicas en cuanto al momento óptimo de venta de los animales en cría o invernada de un sistema ganadero incorporando sus riesgos climático-tecnológicos y de mercado bajo la metodología de opciones reales. Se identificaron 112 alternativas, donde el valor actual de la decisión de venta de los terneros al destete fue de 103U$ cab-1. La valuación de la opción real mediante la invernada propia de los mismos fue de 86 U$ cab-1. Los resultados hallados permitieron cuantificar las alternativas de crecimiento y sus parámetros de riesgo para abordar estrategias de incremento de valor más eficientes.
Brechas en el desarrollo de cuentas ecosistémicas para Argentina, riesgos y oportunidades para su Parque Chaqueño
Authors: Caride Verónica
Published: December 2024

El Gran Chaco es una de las regiones con mayor biodiversidad del mundo y uno de los ecosistemas más grandes de América Latina. Argentina representa el 62% de la región a través de su Parque Chaqueño, siendo ésta el área forestal más grande y presentando a su vez la tasa más alta de deforestación del país. Esta deforestación implica no sólo grandes riesgos en términos ambientales y sociales sino también económicos. Si bien la Argentina cuenta con la Ley 26.331 de Presupuestos Mínimos de protección ambiental para los bosques nativos (conocida como Ley de Bosques) desde el año 2007, el nivel de cumplimiento de su financiamiento nunca superó el 10%. Se requiere por tanto de financiamiento internacional y la implementación de un esquema de pagos por servicios ecosistémicos eficientes, que cubra los costos de oportunidad de los propietarios de tierras con cobertura forestal nativa, para poder alcanzar un desarrollo sustentable en el país y la región. Sin embargo, para poder materializarlo se debe contar con metodologías de valoración y un sistema de contabilidad nacional de servicios ecosistémicos desarrollado. En el presente trabajo se realizará una revisión de la implementación de la Cuenta de los Ecosistemas en Argentina, adoptada por Naciones Unidas en marzo 2021, con el objetivo de contribuir en la generación de conocimiento técnico necesario para lograr identificar brechas, riesgos y oportunidades para la Argentina y su Parque Chaqueño en términos de contabilidad ecosistémica, fundamental para lograr el acceso al financiamiento necesario para el pago de sus servicios ecosistémicos.
RESVERATROL THERAPEUTIC POTENTIAL IN AGE-RELATED DISEASES
Authors: Yıldırım Tuba Demirci
Published: December 2024

Aging is a multifaceted biological process marked by the gradual deterioration of physiological systems, heightened susceptibility to illnesses, and eventual mortality. With the increasing proportion of older individuals worldwide, interest in strategies to decelerate aging and support healthy longevity has intensified. Resveratrol, a naturally occurring polyphenol present in grapes, berries, and various plant-derived foods, has attracted widespread attention for its potential anti-aging properties. This compound exerts its effects through multiple pathways, such as activating sirtuins, combating oxidative stress, improving mitochondrial performance, exerting anti-inflammatory effects, and protecting telomeres. Research has indicated that resveratrol can alleviate age-related conditions, including neurodegenerative diseases, cardiovascular disorders, sarcopenia, cancer, and diabetes mellitus, as evidenced by both animal studies and human clinical trials. Despite its promising potential as an anti-aging agent, further investigation is necessary to determine appropriate dosages, long-term safety, and efficacy in humans. This review provides an overview of the mechanisms underlying resveratrol’s actions, its impact on age-associated diseases, and its prospects as a therapeutic option for enhancing longevity and quality of life.

The study aims to examine the relationship between physicochemical parameters and the diversity of Brachyuran crabs in the Gulf of Kachchh, Gujarat, from November 2020 to April 2021. The research was conducted at two locations, Vador and GSFC (Gujarat State Fertilizer & Chemical Limited) Jetty near Sikka on the southern coast of the Gulf of Kachchh, using the quadrat method for sampling. Various species diversity indices and attributes were calculated, such as species diversity, richness, species evenness, density, abundance, and frequency. A total of 31 Brachyuran crabs belonging to 26 genera and 14 families were recorded, with 26 and 18 species reported from Vador and GSFC Jetty sites, respectively. The Portunidae family had the highest number of species, followed by the Xanthidae family. Brachyuran crab species were found in habitats including rocky areas, muddy areas, mangroves, sponge-associated areas, seaweed-associated areas, and coral reef-associated areas. During the study period, Thalamita crenata showed the highest average density (no/m2) and abundance along the Sikka coast. An analysis of physicochemical parameters, including air and water temperature, pH, salinity and dissolved oxygen, revealed positive correlation with temperature and salinity and a negative correlation with dissolved oxygen. These findings provide crucial baseline data that can inform the development of conservation and biodiversity management strategies in this region, emphasizing the importance of protecting coastal ecosystems.

Authors: Yıldırım Ayşegül
Published: December 2024

Modern dünyanın en popüler içeceği olan kahve günümüzde birçok kültür ve coğrafyada büyük bir beğeni ile tüketilmektedir. Sadece bir içecek olmaktan öte kendi sosyal ortamını, iletişim tarzını hatta günlük rutinlerini oluşturan kahve Habeşistan’da köklerini alıp Avrupa’ya kadar uzanmıştır. Kahve ve beraberinde gelen kahve kültürünün Osmanlı’daki ilk yansımalarına, siyasal tartışmaların odak noktası oluşuna ve gündelik hayat üzerindeki dönüştürücü tesirine, Osmanlı toplumunun gerçek yaşam mekânları olan mahallerden bakmak gerekir. Hiç şüphe yok ki kahve, Osmanlı’dan Avrupa’ya toplumların yaşamlarında hiç bilmeden sahip oldukları bir boşluğun doldurulmasına vesile olmuştur. Kahvenin kurumsallaşması ile birlikte artan sosyal ilişkiler, çeşitlenen kahveler ve kahve mekânları tarihten günümüze gelişerek devam etmektedir ve bu yolculuğun tarihi köklerini bilmek bir içeceğin tarihini bilmekten çok daha fazla anlam taşımaktadır.
