Vegetables are foodstuffs of plant origin that can be consumed fresh and have various health benefits. However, not a few people do not know the types of vegetables and will find it difficult to find the vegetables they want. This research aims to make it easier for people to find vegetables by classifying them. Researchers developed a model using the Convolutional Neural Network (CNN) method with a total of 15 datasets with a total of 3000 image data. Researchers conducted training datasets with 3 types of epochs, including 20 epochs, 50 epochs and 100 epochs. The training produces accuracy and training loss, with the highest accuracy belonging to Epoch 50 and Epoch 100 and the lowest level of training loss is owned by Epoch 100 with a total of 0.609. However, after the model was deployed, the accuracy results obtained were not as high as the tests conducted on Google Colab. Tests were carried out on several objects, including carrots with an accuracy of 69%, cabbage with an accuracy of 53%, and papaya with an accuracy of 82%. The difference in accuracy results may be caused by objects that are less identical to the datasets or can also be caused by imperfect models. Even so, this application can already be used to classify types of vegetables.

Published: May 2023

Aim: The aim of this paper is an attempt to analyse the determinants of effective cardiopulmonary resuscitation (CPR) performed by medical personnel over a five-year span.
Material and methods: An original research questionnaire was used to collect and process data for the purposes of this retrospective observational study. The research sample consisted of 167 patients aged between 16 and 102 who had in-hospital sudden cardiac arrest (SCA) and underwent cardiopulmonary resuscitation (CPR).
Results: The most common causes of SCA in the study group of patients were cardiovascular diseases, and the mechanism of asystole was responsible for half of the recorded sudden cardiac arrests. While performing CPR, chest compressions were the most frequently applied procedure, whereas defibrillation or the Esmarch (jaw-thrust) maneuver were used less often. The effectiveness of resuscitation in almost a half of the cases was unsatisfactory, whereas the average time of performing resuscitation was 27,83 minutes. Pronouncement of death was made with regard to patients on whom resuscitation was performed for the longest time. On the other hand, among patients who were resuscitated for less than 20 minutes, breathing, blood circulation and con¬sciousness were restored, or only breathing and circulation were restored.
Conclusions: The main cause of sudden cardiac arrest in the study period were non-shockable heart rhythms, whereas the restoration of spontaneous cir¬culation and breathing was achieved in the cases when resuscitation was performed for less than 20 minutes. The survival rate after successful resuscitation is comparable to the results obtained in other hospitals in Poland and Europe, as well as statistical data from scientific publications.

Source and fate of dissolved organic matter in boreal headwater streams
Authors:   , Friesen-Hughes Karl
Published: May 2023

Understanding the source and fate of dissolved organic matter (DOM), a key water quality variable, in boreal headwaters is of critical importance considering the amount of carbon stored and processed in different ecosystem components within the boreal forest and the sensitivity of these processes to climate change. Using historical streamflow and stream chemistry data in combination with direct measurements of the landscape sources of DOM and more detailed stream DOM quality data from 2021 at the IISD-ELA, I examined how the terrestrial source of DOM influences the quantity and quality of DOM in three boreal headwater streams. Using historical stream data from 1981-2021, I found that concentration-discharge (c-Q) relationships varied based on both catchment characteristics and hydrological conditions. Streams draining upland-dominated catchments were more often transport-limited (i.e., concentration increased with increasing flow), whereas a wetland-dominated stream was more often source-limited (i.e., concentration decreased with increasing flow) in terms of stream DOM concentration. DOM concentration and quality data in soil leachate indicated that streamwater had DOM characteristics suggesting it originated from near-stream organic soils, while after the drought the DOM came proportionally more from distal mineral soils (in addition to near-stream organic soil contributions). I showed that the severe drought in 2021 made streams with varying landscape characteristics respond similarly to the post-drought flush. These findings also illustrate that while c-Q relationships may be different among streams draining upland-dominated and wetland-dominated catchments as a result of the different abilities of these landscape to accumulate and mobilize DOM, DOM quality responded to this drought to post-drought flush synchronously among all three streams. As climate change will alter the frequency, duration, and severity of future hydrological conditions, this has repercussions for the DOM dynamics in headwater streams and the resulting water quality downstream.

Authors: El Merroun Mohamed , Bartók István János , Alkhlaifat Osama
Published: May 2023

In the existing literature, Industry 4.0 and its potential impact on environmental sustainability have been studied from different perspectives. However, Industry 4.0 is a concept that gathers different technologies that are not necessarily combined. It is clear that the combination of different technologies is the core value of Industry 4.0. However, the examination of each technology separately is crucial for determining the right combination of technologies for each specific case. Therefore, the following research provides a systematic literature review (SLR) of each technology included in Industry 4.0 and its effects on environmental sustainability aspects based on 107 research papers. 417 articles from the SCOPUS database, which contain the word Industry 4.0 in the title, abstract, and/or in the indexed keywords, were scanned by the command-line program Astrogrep to find the most common Industry 4.0 technologies. The results revealed that the Internet of Things (IoT) was mentioned 252 times, Artificial Intelligence/Machine Learning (AI/ML) 81 times, Simulation 38 times, Blockchain 30 times, Augmented Reality (AG) 27 times, and Additive Manufacturing (3D printers) 23 times. First, the study reviews the potential effects of the six technologies on different aspects of environmental sustainability. Later on, the challenges faced by organizations when applying these technologies for environmental purposes were reviewed, and new research scopes and future research directions were highlighted.
The Role of Pattern Recognition Receptor (PRR) in the Body's Defense System: A Narrative Literature Review
Authors: Ziske Maritska  , Hidayat Rachmat
Published: May 2023

Each cell has receptors on the cell surface that specifically bind to solutes (ligands) produced during tissue damage or infection. This review aimed to describe the role of PRR in the human body's defense system. The binding of the ligand to its receptor results in the activation of intracellular signaling pathways and cell activation. The B and T lymphocytes of the adaptive immune system have developed surface receptors (that is, the T-cell receptor, or TCR, and the B-cell receptor, or BCR) that bind a broad spectrum of antigens. The cells involved in innate resistance have developed a distinct set of receptors that recognize a much more limited array of specific molecules. These are called pattern recognition receptor (PRR), and they recognize the molecular patterns in infectious agents or their products (pathogen-associated molecular patterns, or PAMP) or products of cellular damage (necrosis or apoptosis; molecular pattern-associated damage, or DAMPs). In conclusion, the pattern recognition receptor (PRR) is a receptor complex that interacts with various molecules, such as PAMP and DAMPs. PRR bonds with these various molecules and play a role in various actions of innate immunity and adaptive immunity.
Inflammatory Response Plays a Role in Innate Immunity: A Narrative Literature Review
Authors: Rara Inggarsih  , Hidayat Rachmat
Published: May 2023

The inflammatory response is the rapid initiation and interplay of humoral (dissolved in the blood) and cellular systems designed to limit the degree of tissue damage, destroy infectious microorganisms, initiate an adaptive immune response, and initiate the healing process. This review aimed to comprehensively describe the role of the inflammatory response in innate immunity. Three key plasma protein systems are essential for an effective inflammatory response. These are the complement system, clotting system, and kinin system. Although each system has a unique role in inflammation, they also share many similarities. Each system consists of several proteins in the blood. To prevent activation in unnecessary situations, each protein is normally in an inactive form. Some proteins are enzymes that circulate in an inactive form as proenzymes. Each system contains several proteins that can be activated at the start of inflammation. Cells of the innate and acquired immune systems are recruited and activated by biochemical mediators produced at sites of cell damage. These molecules originate from destroyed or damaged cells, contaminating microbes, activation of plasma protein systems, or secretion by other cells of the innate or acquired immune system. Activation may result in the cell acquiring a function essential for the inflammatory response or inducing the release of additional cellular products that promote inflammation, or both. In conclusion, inflammatory cells and various protein systems (complement, kinin, and clotting), together with the substances they produce, act at the site of tissue injury to limit the extent of damage, kill microorganisms, and remove debris in preparation for healing: tissue regeneration or repair.

Design and Modeling of Hybrid Electric Vehicle Powered by Solar and Fuel Cell Energy with Quadratic Buck/Boost Converter
Authors: Divya G. , S. Venkata Padmavathi
Published: May 2023

Considering technological advancements and international standards mandating reduced greenhouse gas emissions, automobile manufacturers have shifted their focus toward innovative technologies related to fuel-cell electric vehicles. Despite having an all-electric powertrain, fuel cell electric vehicles (FCEVs) utilize a fuel cell stack as their energy source, which runs on hydrogen and results in the emission of only water and heat. Due to the absence of tailpipe pollutants, fuel-cell electric vehicles are considered zero-emission vehicles. Among fuel cell types, low-temperature and low-pressure fuel cells, such as Proton Exchange Membrane Fuel Cells (PEMFCs), are well-suited for vehicular applications as they exhibit high power density, operate at lower temperatures (60-80°C), and are less prone to corrosion than other types of fuel cells. The main objective of this paper is to investigate solar-assisted electric fuel cell vehicles that efficiently integrate the fuel cell system with an electrolyzer and solar power to fulfill the fluctuating power demands of the electric motor and auxiliary systems. A novel EV configuration with a fuel cell, electrolyzer and onboard PV cell is proposed. An onboard PV cell can assist the fuel cell when the irradiation is enough to generate the power. During the idle conditions of vehicles, PV-generated power can be converted into chemical energy using an electrolyzer and generated hydrogen can be stored in a hydrogen tank. To match the voltage required by the motor and sources a quadratic bidirectional buck-boost converter is employed. The proposed configuration is examined by considering variable irradiance and variable speed values. To obtain the maximum power output from the photovoltaic (PV) panel, a Maximum Power Point Tracking (MPPT) algorithm is employed to regulate the PV system. To enhance the efficiency and cost-effectiveness of PV systems, an enhanced version of the incremental conductance algorithm is utilized as the MPPT control strategy. Outer voltage and inner current control are adopted to regulate the DC output voltage of the QBBC converter. An indirect vector-controlled induction motor is used as vehicle drive. Simulations are performed to investigate the proposed EV configuration in MATLAB/SIMULINK.

La vida después del Accidente Ofídico
Authors: Guerra-Centeno Dennis
Published: May 2023

El accidente ofídico o envenenamiento por serpiente es una enfermedad desatendida de distribución mundial que afecta principalmente a los campesinos pobres de las áreas tropicales. La mayoría de las investigaciones publicadas sobre el tema abordan aspectos clínicos o epidemiológicos de la enfermedad y muy pocas veces se refieren a la dimensión social del sujeto víctima, sobre todo, abordado desde el paradigma cualitativo. Con el objetivo de mejorar la comprensión del significado de las secuelas que acompañarán al sujeto víctima de accidente ofídico a lo largo de su vida, se realizó un estudio cualitativo bajo la perspectiva fenomenológica. La descripción de los significados se construyó a partir del estudio de sobrevivientes de accidente ofídico residentes en las aldeas San Andrés y El Caoba, en Flores, Petén, Guatemala. Se identificaron tres categorías descriptivas. Se describen con más detalle los casos paradigmáticos de dos sujetos cuyo accidente ofídico tuvo un impacto profundo en sus vidas, tanto físico como psicológico. Estas descripciones idiográficas siguen la corriente de la fenomenología eidética husserliana y constituyen documentos inéditos sobre las secuelas de una enfermedad desatendida a nivel mundial.
Análisis Doctrinario de la Tenencia Compartida en el Ecuador: Criterios y Factores de Valoración
Authors: Pico Acosta Adrian Bolivar
Published: May 2023

El Ecuador reconoce la figura jurídica de la tenencia de menores, establecida y regulada en el Código Orgánico de la Niñez y Adolescencia, la doctrina ha establecido que esta es una responsabilidad y obligación compartida entre sus progenitores tanto en varios aspectos. Sin embargo, surgen situaciones de vulnerabilidad de los menores como la alienación parental, ante ello, es importante que el poder judicial logre enfocar sus actuaciones al momento de administrar justicia en la búsqueda del bienestar del menor, adjudicando la tenencia en pro de las mejores condiciones para el mismo.

La principal problemática es la ejecución de la normativa al momento de existir la disolución del vínculo conyugal, dejando al menor en una situación de vulnerabilidad para la determinación de su tenencia por uno de sus progenitores; siendo importante que el juzgador evidencie y valore todos los elementos que conllevan a que los niños o adolescentes se encuentre en un lugar de libre desarrollo emocional, económico, etc.

La metodología utilizada en este ensayo es de carácter cualitativa, con enfoque critico-jurídico que tiene soporte en el método analítico bibliográfico y analítico sintético, de tipo descriptivo de la normativa jurídica actual sobre la tenencia de menores y de la resolución judicial de la Corte Constitucional frente a la derogación de la preferencia materna en pro de una búsqueda de igualdad y sobre todo del ejercicio  y corresponsabilidad de la tenencia compartida dejando de lado los roles de género y permitiendo al menor vivir en un ambiente sano y libre de violencia.

La implementación de las estrategias pedagógicas en los procesos áulicos tiene una influencia positiva en el desarrollo socioemocional de los estudiantes, ya que les permite desarrollar habilidades que les serán útiles a lo largo de su vida, tanto en el ámbito personal como en el profesional. Además, al fomentar un ambiente de respeto, colaboración y empatía en el aula, se contribuye a crear un clima escolar más positivo y propicio para el aprendizaje. El objetivo del estudio es establecer la influencia de las estrategias pedagógicas en el desarrollo socioemocional de los educandos en las diferentes instituciones educativas. En relación al marco metodológico es un estudio con enfoque cuantitativo con diseño pre-experimental; para la recolección de datos se utilizó como técnica la encuesta y como instrumento al cuestionario; de igual forma, para procesar los datos se utilizó el software IBM SPSS Statistics. Los hallazgos encontrados dieron como resultado que la implementación de las estrategias pedagógicas fomentó el aprendizaje cooperativo entre los educandos permitiéndoles trabajar en equipos para alcanzar una meta común, donde los estudiantes aprenden a trabajar colaborativamente, a comunicarse y a respetar las opiniones de sus compañeros, lo que contribuye a desarrollar habilidades socioemocionales como la empatía y la colaboración.

Esta investigación tiene como objetivo estimar y evaluar umbrales de lluvia locales que desencadenan movimientos de flujo de escombros, entorno al área de la quebrada Rosayoc/Batán – distrito de San Rafael – provincia de Ambo – departamento de Huánuco. Por otra parte, se realiza una metodología empírico-estadístico; por cual, en este estudio, se han hecho intentos para comprender mejor la relación entre la precipitación y el desarrollo de procesos de movimientos de flujo de escombros. Además, el umbral mínimo LA1 de 18 días posee mayores precipitaciones que el umbral mínimo LA1 de 5 días, siendo el más peligroso. Así como, el umbral mínimo LA2 de 5 días tiene las mayores precipitaciones que los umbrales mínimos LA2 de 6 y 7 días. A esto se añade que, los umbrales LA1 de 5 y 18 días tienen incertidumbres menores y cercanas al 10%; asimismo, el mayor porcentaje de predicción de los umbrales LA1, lo posee el umbral LA1 de 18 días con 49%. De igual modo, los umbrales LA2 de 5, 6 y 7 días tienen incertidumbres menores al 10%; y el mayor porcentaje de predicción de los umbrales LA2, lo posee el umbral LA2 de 7 días con 62%. Por último, los resultados de este trabajo demuestran el potencial de los umbrales de lluvia basados ​en la relación de la precipitación de lluvia con los eventos de movimientos de flujo de escombros, siendo importante para el monitoreo y pronóstico de este fenómeno.

Uno de los objetivos que proponemos para realizar esta investigación es determinar los cambios que introducen a la escritura en las redes sociales y cómo es utilizado en el campo educativo, por parte de los estudiantes de Tercero y Segundo de Bachillerato de la Unidad Educativa San Gerardo, de la provincia de Chimborazo.

El método utilizado para esta investigación es cuantitativo y cualitativo, se interactuó con los alumnos en las redes sociales y el diseño fue narrativo porque se describen los cambios de palabras. No interesa buscar una relación entre el fenómeno de las campos sociales, ni el impacto en el sistema educativo, sino observar, comprender e interpretar la adopción de nuevas palabras, lo que piensan los alumnos en su contexto estudiantil y cómo lo utilizan.

Los estudiantes mediante el proceso de comunicación y necesidad académica, han generado un nuevo vocabulario, por lo cual se evidencia en sus mensajes escritos. La o las nuevas palabras generadas en las redes sociales como: Facebook, wasap, se encontró gracias a la aplicación de la técnica de la observación directa e indirecta de los mensajes y la aplicación de una encuesta que confirmaron lo planteado.

  Como resultado de la investigación podemos señalar que los alumnos han desarrollado una lengua común, es decir han conforman una comunidad lingüística, con una lengua que sirve como medio de comunicación, para ello se han utilizado: abreviaciones, cambio, combinación de letras, letras y números o viceversa, empleo de moticones, etc. Dando lugar a mutaciones, metaplasmo y a un nuevo léxico.

La calidad educativa ofrece a los actores principales el alcance de metas para permitirles ser ciudadanos interculturales dentro de una sociedad con igualdad de oportunidades. De allí, la importancia de una revisión constante del proceso de enseñanza y aprendizaje, en caso especial para este artículo tipo ensayo, del aprendizaje matemático en el sistema educativo ecuatoriano, puesto que, conocer esta ciencia va mucho más allá de repetir axiomas o ser capaz de identificar diversos objetos matemáticos. Cónsono a esto, revistió la imperiosa necesidad de analizar la calidad y pertinencia del aprendizaje matemático en el sistema educativo ecuatoriano a nivel de bachillerato a través de las siguientes interrogantes pedagógicas: ¿Cuál es el proceso a desarrollar en el estudiante para alcanzar un aprendizaje matemático? ¿Qué deben aprender los estudiantes ecuatorianos de bachillerato en una clase de matemáticas luego de un abrupto aislamiento? ¿Cuál debe ser la orientación apropiada del docente para el logro del éxito en el aprendizaje matemático? ¿Cómo deben ser enfocadas las estrategias de enseñanza para que el aprendizaje matemático sea de calidad y de pertinencia a la realidad del país? Se concluye que, las tendencias pedagógicas evidencian cambios para el logro de la competencia matemática en la construcción del conocimiento en pro de desarrollar el pensamiento lógico acorde con la realidad del Ecuador por parte de los estudiantes.
