Brief Review: Pancreatic Islet Transplantation for Type 1 Diabetes in Humans
Authors: Robertson R. Paul
Published: May 2023

Pancreatic islet transplantation (ITx) has moved from the experimental phase of development to a position of an accepted and appropriate procedure to apply in clinical medicine. The primary indication for use of ITx is for management of dangerous and recurrent hypoglycemia secondary to use of exogenous insulin for management of hyperglycemia in people with type 1 diabetes. ITx involves procurement of a pancreas donated by a person who has died. The organ is taken to a specialized laboratory for isolation of islets that will be infused into the liver via a cannula put into the hepatic portal vein of an awake recipient by a radiologist. Success rates of maintaining normal blood glucose after the ITx are very high and almost as effective as transplanting an entire pancreas via surgery. Often more than one procedure is required to achieve success. One major attraction to the procedure is that it avoids the more dangerous and complicated procedure of surgical transplantation of the entire pancreas. However, in both instances recipients must undergo and maintain immunosuppressive drugs to avoid rejection of the islets. ITx is also used for management of patients with chronic, painful pancreatitis who undergo pancreatectomy. In this instance the patient’s own islets are returned by infusion into the liver as is done with type 1 diabetes patients. No immunosuppression is required. Success rates of autoislet transplantations are also quite high if a sufficiently mass of islets can be recovered from the resected pancreas.

It has been stated repeatedly that delays in government spending in the past have been caused, in part, by problems with procurement. The PHilMech Budget has been citing procurement as an excuse for underspending for many years. The cumulative disbursement outcome for 2019 was lower than the programmed spending for the year by approximately Php 48 million, or about 23% of utilization in the Regular fund, and by approximately 9 million, or about 9% in the Rice Competitiveness Enhancement Fund. Although not all of the savings result from underspending (i.e., about 21% of the amount is attributable to a combination of greater interest payment savings and net lending, which reflects prudent debt management by the government), the majority is reflected as a decline in agency performance in disbursements and budget utilization. The problem of procurement management delays in PHilMech has been enormous. Its effects were so profound that it frequently slows down the execution of strategic planning. This essay examines the management and procurement law flaws that contributed to the delays in the PHilMech projects' implementation. The analysis's findings showed that poor management, ineffective planning and scheduling, and cash flow and financial difficulties faced by management were the major issues that contributed to delays. Several actions are suggested.

Due to the high utility costs in Cabanatuan City, the solar panel system is rapidly approaching. People in the middle and lower income classes of the country particularly feel the effects of inflation. In order to address the ongoing rise in oil prices and pollution, the government has made the development of renewable energy one of its top priorities. In order to help consumers reduce their utility costs, save money, and produce greener energy, a study on the installation of a solar panel system at home was carried out. The researchers gathered some data from consumers to be utilized as the basis for the contractors' computations, where the adoption of a 3kw on-grid solar panel system was recommended to those respondents with power bills under ₱2,400. The project costs approximately ₱150,000 in total, including installation and permits, and can save approximately ₱2,300 monthly. This investment has a 5.4-year payback period and a total savings of ₱402,000 over a 20-year period. The consumption analysis revealed a sensitive effect on savings and investment payback periods. The study proved that the project's long-term savings can be more than double the initial investment. A SWOT analysis was also performed to highlight the advantages and disadvantages of having an on-grid solar panel, as well as the benefits of clean energy and gas reduction in our environment that future generations could benefit from. The project's cost-benefit is a win-win investment for everyone who wants to save money while also enjoying cleaner air in the long run.

La emergencia sanitaria a nivel mundial finalmente ha quedado atrás, al menos así lo estipuló el pasado cinco de mayo de 2023 la Organización Mundial de la Salud (unam; Linde, 2023). Sin embargo, eso no borra las secuelas, sean negativas o positivas, que dejó en la población, sobre todo en la salud física y mental. Lo que nos trae al día de hoy, a aquellas consecuencias que dejó en nosotros y con las que viviremos unos años más: la salud física cobró mayor importancia a partir del año 2020, junto con acciones que se volvieron una tarea cotidiana, como el constante lavado de manos, el uso del gel antibacterial y del cubrebocas. Pero, a partir de esta pandemia, ¿aprendimos algo nuevo? O continuaremos cometiendo errores que afecten a nuestra salud, a pesar de lo que ya sabemos.

Published: May 2023

Las evaluaciones estandarizadas en el ámbito educativo tienen una larga historia, que inicia a principios de siglo XX. El campo de la Psicología y de la Educación ha impactado enormemente el mundo educativo y, últimamente, ha servido para diseñar políticas públicas y para rendir cuentas a la sociedad. La principal característica de las pruebas estandarizadas es que pueden administrarse a una gran cantidad de personas, cuyas respuestas se califican de manera automática con dispositivos electrónicos. Su gran desventaja radica en que utilizan, principalmente, el formato de selección de respuestas que hace un tanto artificial la evaluación. A pesar de esta limitación, las evaluaciones estandarizadas se utilizan con una gran variedad de propósitos: desde la admisión a instituciones educativas hasta la evaluación de la calidad educativa de un país. A lo largo de su historia, las evaluaciones estandarizadas han sido objeto de críticas, algunas de ellas justas y otras no. Dada su importancia, el propósito de este texto es precisar lo que se entiende por evaluaciones estandarizadas de aprendizaje, describir su origen y evolución en el ámbito educativo, explicar sus principales usos y puntualizar las limitaciones y retos que tendrán.
Plantas medicinales: si es natural… ¿No hace daño?
Authors: López Rosas Carlos Alberto , Olguin Guerrero Mónica Carolina , Hernández Rosas Fabiola
Published: May 2023

El uso terapéutico de plantas medicinales como sustitutos de medicamentos, o en combinación con estos, ha sido objeto de debate en los últimos años debido a la falta de evidencia científica que respalde sus efectos terapéuticos y a la escasa documentación sobre sus efectos biológicos y farmacológicos. Por lo tanto, es importante continuar investigando su utilización terapéutica, especialmente en términos de su toxicidad. En México, al igual que en otras partes del mundo, las plantas medicinales se utilizan como tratamiento primario para malestares moderados a leves, principalmente debido a la falta de acceso y/o a los altos costos de los medicamentos, así como al arraigo cultural de la medicina ancestral. El uso de plantas medicinales como alternativa terapéutica podría ser una opción viable, sin embargo, es necesario estar bien informado sobre su uso y eficacia para obtener los resultados esperados.

Published: May 2023

To improve analysis of the current Eastern Pacific Green (EPG) turtle population status, a spatial assessment is needed on their presence and frequency in their frequented habitats. This study aims to develop a framework from which a baseline study could be undertaken focused on EPG turtles surrounding the waters of Parque Nacional Zona Marina from the Archipiélago Espíritu Santo. Two years of data and a research survey focused on Local Ecological Knowledge (LEK) from ecotourism guides operating out of La Paz, BCS, México were used. Due to the University of California’s Institutional Review Board’s (IRB) protocol and small sample size of survey participants, survey data may not be used to extrapolate to the population of ecotourism operators in La Paz. Although past studies have integrated LEK from fishers, this is the first study to introduce LEK from the ecotourism sector to inform EPG turtle conservation efforts in México. The results from this project will contribute to a better understanding and further insight of how this species utilizes this area.

Published: May 2023

El agua electrolizada (AE) es un agente antimicrobiano generado mediante electrólisis y es considerado de amplio espectro y en su composición química están presentes compuestos oxidantes. El AE es empleada en múltiples campos como la industria alimentaria, así como en hospitales y algunos laboratorios de análisis clínicos. El agua electrolizada neutra (AEN) presenta ventajas sobre el agua electrolizada alcalina y ácida, por su baja toxicidad, menor producción de residuos cancerígenos, no corroe las superficies metálicas, y su producción es in situ y de bajo costo. El objetivo de esta revisión fue analizar las áreas de aplicación del AE, así como detectar nuevas posibles áreas de estudio. Se utilizaron buscadores internacionales con un criterio de inclusión del año 2000 al 2022 y se encontraron un total de 768 artículos. En ellos se destaca su efecto antimicrobiano sobre las hortalizas/frutas, la carne y las superficies inertes con 37.8, 22.6 y 17.2 %, respectivamente. La aplicación del AEN en la carne de pescado es en la que más se ha estudiado, seguida por la lechuga, la manzana y la fresa. En contraste, es escasa la información en el área de la salud, así como en el ámbito sensorial de los alimentos y en la germinación de semillas.

Este trabajo aborda el estudio de las decisiones políticas fundamentales vaciadas en el texto original de la Constitución Política del Estado, en su relación con la realidad social con la que deben ser acordes. A partir de la exploración teórico conceptual de la cuestión, y con base en una metodología crítico-valorativa, nos aproximamos a las manifestaciones sociales de reciente configuración que evidencian nuevas expresiones de orden constitucional que la norma fundamental no contiene. A partir de ello, postulamos la tesis de las decisiones políticas fundacionales para sostener que las nuevas realidades de nuestras sociedades complejas y demandantes pueden ser identificadas como nuevas decisiones políticas fundamentales que, a partir de un ejercicio hermenéutico y heurístico deben ser incorporadas al texto constitucional.
El Estado social de derecho expósito: la sostenibilidad fiscal y la regresión judicial de derechos sociales en Colombia
Authors: Duarte Martínez Carlos Arturo
Published: May 2023

En este texto se analizan las sentencias de unificación 1073 de 2012 y 230 de 2015, y se expone cómo en ellas la Corte Constitucional promueve la regresión a derechos sociales. Los efectos que estas sentencias tienen dentro del sistema de control de constitucionalidad permiten identificar una elusión constitucional, pues es imposible que el principio de no regresividad se aplique como un criterio de justiciabilidad. Estas decisiones han sido reiteradas en años posteriores, y dejan sin garantías judiciales a la cláusula de Estado social de derecho de la Constitución de 1991 frente a la sostenibilidad fiscal. Esto también viola el estándar del recurso judicial efectivo consagrado en la Convención Americana sobre Derechos Humanos.
Análisis crítico de la STC 172/2020 (Pleno) en cuanto a la constitucionalidad del artículo 20.2b de la Ley de Seguridad Ciudadana
Authors: Guillén Pérez Valentín
Published: May 2023

La sentencia del Tribunal Constitucional 172/2020, del 19 de noviembre, ha resuelto reciente y definitivamente el Recurso de Inconstitucionalidad 2896/2015, interpuesto en contra ex artículo 20.2 de la Ley de Seguridad Ciudadana. Su redacción se ajusta al marco constitucional, ya que, según se arguye en la misma, no vulnera el derecho a la intimidad corporal establecido en el artículo 18.1 de la Constitución Española. A la luz de la presente sentencia, se ha realizado un estudio minucioso sobre los aspectos más relevantes de esta figura de prospección corporal que hemos denominado “desnudo parcial”, encuadrada en el apartado “b” ex artículo 20.2, que de su tenor literal expresa como “dejar a la vista partes del cuerpo normalmente cubiertas por ropa”.
Comentario a la sentencia de la Suprema Corte de Justicia de México que reconoce el supuesto derecho a interrumpir el embarazo
Authors: Adame Goddard Jorge
Published: May 2023

La Suprema Corte de Justicia de México ha resuelto que la Constitución mexicana contiene el derecho de las mujeres a interrumpir el embarazo en un plazo breve posterior a la concepción. Este comentario demuestra que la decisión no tiene fundamento ni en la Constitución mexicana ni en los tratados internacionales de derechos humanos, y que parte de una deficiente percepción de la realidad de lo que es el embrión humano, que lleva a la infundada conclusión de que mientras no cumpla cierta edad, puede ser tratado como una cosa o un animal.
La ponderación de derechos de Robert Alexy en una decisión judicial del máximo tribunal en México
Authors: Rodríguez Santibáñez Iliana , Álvarez Bautista Priscila
Published: May 2023

Los derechos constitucionales y su proporcionalidad, o ponderación de derechos dentro del ámbito jurídico, es un método utilizado para saber qué derecho humano debe prevalecer ante otro cuando ambos colisionan o se contraponen. En México, la Suprema Corte de Justicia de la Nación, mediante la Acción de inconstitucionalidad 146/2007, realizó la ponderación del derecho a la vida del no nacido contra los derechos de la madre (salud, sexuales y reproductivos y libre desarrollo de la personalidad). Se determinó que estos últimos deben predominar sobre el derecho a la vida, lo cual dio pauta a la despenalización del aborto en la Ciudad de México. En la presente investigación se analiza, mediante el método deductivo y sintético, el razonamiento de ponderación realizado por la Suprema Corte en su resolución, y los derechos fundamentales que se encuentran dentro de la misma.

Published: May 2023

Abstract: Human emotion detection using machine learning is an emerging field with significant potential for various applications. In this article, we present a test dataset-based automated approach based on convolutional neural networks (CNN) for precisely identifying human emotions from facial expressions. The dataset includes a wide variety of facial expressions that depict various emotions, and our model was trained on a sizable dataset of 20,000 images, encompassing a broad range of facial expressions signifying various emotions, such as joy, sorrow, neutral, fear, surprise, and disgust. To enhance the model's performance, we used a variety of hyperparameter tweaking strategies, such as data augmentation. This research emphasises the need of using machine learning to precisely detect and evaluate human emotions, which can have important ramifications in areas like psychology, marketing, and human-computer interaction.
Analysis of Walking Pattern using LRCN for Early Diagnosis of Dementia in Elderly Patients
Authors: Salahuddin Rimsha
Published: May 2023

Abstract: Analysis of walking pattern using LRCN for early diagnosis of Dementia in elderly patients has emerged as one of the most important study areas in the fields of health and human-machine interaction in recent years. Many artificial intelligencebased models for activity recognition have been developed; however, these algorithms fail to extract spatial and temporal data, resulting in poor real-world long-term HAR performance. Furthermore, in the literature, a restricted number of datasets for physical activity recognition with a smaller number of activities are publicly available. Given these constraints, we create a hybrid model for activity recognition that combines Convolutional Neural Network (CNN) and Long Short-Term Memory (LSTM). Long-Short Term Memory (LSTM) networks are designed to work with sequence data, while Convolutional Neural Networks (CNN) are helpful for improving understanding of picture information. CNN can be used to extract spatial data at points in a series (video). The LSTM layer is granted authority for temporal sequence modelling with extracted spatial characteristics in situ, whereas the convolution layer is responsible for evaluating spatial features from the frames. 50 activity categories, 25 video groups per activity category, 133 medium videos per activity category, and more make up the UCF50- Action Recognition Dataset. 320 frames per second, 199 frames per video, 240 frames each for each video. Each video is an average of 26 intermediate frames per second. We determine which model performs best by analysing its Loss and Accuracy curves, then we test that model using certain testing films. The drawback of this paper is that most persons performing various duties cannot use our vision.

Published: May 2023

Abstract: Air conditioning system is necessary in automobile to maintain the comfort condition. Therefore, it is important to study transient response of vehicle under real driving conditions. The Heat Balance Method (HBM) is used for estimating the heating and cooling loads which develops inside the vehicle cabin. The Load Calculation of Automobile Air Conditioning System is calculated and presented. An hourly cooling load is calculated in Tirunelveli region with respect to its latitude. Tons of refrigeration required is also found out from the cooling load calculation and a review on cooling load calculation is also presented. This study gives overall cooling load and AC power consumption which can be used by HVAC engineers to design more efficient car AC systems. Only by knowing the cooling load and source of thermal load, we can develop intelligent system to reduce AC consumption. Environmental Control System (ECS) is a generic term used in aircraft industry for maintaining the required air temperature and pressure inside passenger and crew compartment. The real challenge for an ECS is to operate and supply adequate cooling over a wide range of ground and flight conditions in a most reliable and efficient manner. The most important aspect of ECS is to know the cabin heat loads during air cooling or air heating phases. A precise calculation of aircraft heat load would be a long process requiring detailed knowledge of the aircraft structure and of the quantities involved in the mechanism of heat pick up and interchange in the cabin. This paper describes a method that may be applied in calculating the heat load for any aircraft and calculations are shown for a typical light transport aircraft under the conditions that, the cabin altitude is maintained within 0 ft to 8000 ft (2438.4m) for the aircraft altitude of 0 ft to 25000ft (7620m). The system shall be capable of maintaining temperatures within 59°F to 75°F (15°C to 30°C).

Abstract: This paper proposes an IoT-based safety system for SAE BAJA All-Terrain Vehicles (ATVs) to improve the safety of riders. The system consists of intelligent safety enhancement system which is integrated with the vehicle to collect data on its location, SOS alert, speed, acceleration, and other important parameters. The collected data is then transmitted to a cloud-based server via wireless communication protocols such as Wi-Fi or cellular network. In this project, we have built an IoT based accident detection with the help of Nodemcu ESP8266 Wi-Fi module and a vibration signal which detect the accidents and send an emergency warning message. The system constitutes of single – board embedded system that has Nodemcu ESP8266 connected to IoT. Nodemcu ESP8266 is an open – source based firmware and development board specially targeted for IoT based applications. The proposed system also includes a remote monitoring and control feature, allowing the rider's friends, family members, or emergency services to track the location and status of the ATV in case of an emergency. Moreover, the system can also be used to monitor the vehicle's maintenance status and provide proactive maintenance recommendations to ensure its optimal performance and longevity. The experimental results demonstrate that the proposed system is effective in enhancing the safety consideration of ATV riders through Blynk – IoT platform and can significantly reduce the risk of accidents through crash alert system. The system can also be easily integrated with other IoT devices and platforms, making it highly scalable and adaptable to different types of vehicles and environments

Published: May 2023

Abstract: Chatbots are computer programs that automatically respond to messages and can be configured to respond the same way every time, to respond differently to messages with specific keywords, and even to use machine learning to adapt their responses to the situation. Users can communicate with artificial intelligence using a text or voice interface using chatbots. Alzheimer's is a chronic neurological illness whose root cause is unclear. Since there is no recognized cure, patient care is mostly focused on creating a comfortable atmosphere for them and supporting the caretakers. In the proposed model, we have redesigned the chatbot's architecture to be able to follow the patient's movement with location and if the patient wanders or moves away from their house, voice notes-based guidance and navigation is used to help them. The system's main job is to carry out memory training operations using names and information of well-known people, locations, and events that may be dynamically

Ixora coccinea, commonly known as a jungle of geranium and red Ixora evergreen shrubs found throughout India. The plant is crucial for several medicinal purposes, including inflammation, wound healing, diarrhea, and cancer. This study aimed to determine the anti-inflammatory activity of Ixora coccinea extracts and the expression of inflammatory genes in cell lines treated with Ixora coccinea extracts. First, the roots of Ixora coccinea were extracted using a methanol solvent. MTT assay was carried out to determine the viability of cells after treatment with different concentrations of the extracts. Then, the Hen egg testchorioallantoic membrane (HET-CAM) assay was used as an in vivo model for chronic inflammation. This method was performed to evaluate anti-inflammatory activity by inhibiting membrane irritation on the chorioallantoic membrane, in which irritation was induced by sodium dodecyl sulfate (SDS). Then, the commercial cell line of stem cells of human exfoliated deciduous teeth cells (SHED) was cultured and total RNA was extracted, followed by reverse transcription cDNA synthesis. Multiplex PCR was performed to detect the expression levels of TNF-α, IL-1β, IL-6, IL-8, and TGF-β in both cell types. The result showed that the highest viability of cells was 78.3 % at a concentration of 1.56 mg/ml. It was found that Ixora coccinea root extracts showed good anti-inflammatory at a concentration of 1.56 mg/ml. Ixora coccinea root extracts showed good anti-inflammatory activity with 80% inhibition on the chorioallantoic membrane compared to Indomethacin, which showed 85% inhibition. Ixora coccinea root extracts showed potent anti-inflammatory effects by enhancing immune response through upregulation of inflammatory cytokines, including IL-1β, IL-6, IL-8, and TGF-β as detected by Multiplex PCR. However, the Ixora coccinea root extracts do not affect TNF-α and GMCSF. In conclusion, the present study has successfully determined the activities of Ixora coccinea extracts. The current study shows a novel finding that Ixora coccinea root extracts possess anti-inflammatory effects through immunomodulatory mechanisms.

Published: May 2023

A digitalizáció elengedhetetlen azon vállalatok számára, amelyek talpon szeretnének maradni a változó üzleti környezetben. Ugyanakkor sok kis- és középvállalkozás még mindig nem él ezzel a lehetőséggel, mely mögött több tényező is állhat, például tudáshiány, vezetési stílus, magas költségek, fenntarthatóság. Jelen tanulmány ezen okok közül a digitalizáció és a fenntarthatóság ellentmondásos kapcsolatára fókuszálva igyekszik feltárni a digitalizációban rejlő lehetőségeket a vállalkozások számára és új fejlesztési stratégiákra is javaslatot tesz. A primer kutatás kvantitatív módszerrel kérdőíves felmérés alapján készült, melyet a V4-országok, valamint Bulgária és Szerbia vállalkozásvezetői és vállalkozói körében végeztünk el, a digitalizáció fenntarthatóságra gyakorolt hatásainak feltárására fókuszálva. Az eredmények alapján a megkérdezett vállalkozások két csoportra oszlottak: az Aggódó Elkötelezettek és a Közömbös Konzervatívok, melyek egymástól eltérő preferenciák alapján képesek elérni a kiegyensúlyozott „digitális fenntarthatóság – fenntartható digitalizáció” („digitarthatóság” – digitainability) állapotát, és lehetővé válik a vállalkozások számára, hogy megfelelő stratégiával képesek legyenek fenntartható működés mellett kiemelt digitalizációs teljesítményt nyújtani.
A digitalizáció mint lehetőség a vezetési tanácsadók számára a COVID–19-járvány idején
Authors: Tokár-Szadai Ágnes
Published: May 2023

A COVID–19-járvány miatti korlátozások valamennyi vezetési tanácsadással foglalkozó vállalkozást és azok ügyfeleit érintették, mely felveti a digitális tanácsadási szolgáltatás igénybevételének, valamint nyújtásának lehetőségét, szükségességét. Tanulmányunkban a járvány idején Északkelet-Magyarországon végzett mélyinterjús kutatásunk alapján azt vizsgáljuk, hogy a vezetési tanácsadók és ügyfeleik nyitottak- e a digitális formában nyújtott szolgáltatásra, illetve igénybevételére. És vajon a tanácsadó cégekben milyen feladatok ellátására, költségek alakulására gyakorol hatást a digitalizáció? A 2020–21-ben végzett mélyinterjús kutatásunkat a vezetési tanácsadók körében 2001-ben és 2005–06-ban kérdőíves felmérés, 2011–12-ben és 2015–16-ban mélyinterjús kutatásunk előzte meg, a tanácsadók információs technológiára való nyitottságának változását ezekkel a felméréseinkkel összehasonlítva vizsgáljuk. Jelen eredményeink alapján a tanácsadók meghatározó hányada nyitott rá, hogy digitális formában nyújtson tanácsadási szolgáltatást, és szívesen alkalmaz újfajta tudásszerzési és -szervezési módszereket. Az ügyfelek a tanácsadóknál sokkal kevésbé nyitottak ilyen formában igénybe venni a tanácsadási szolgáltatást. Nagyon fontosnak tartják a személyes kapcsolatot, szükségesnek találják a nonverbális kommunikációt.

Published: May 2023

Single-cell transcriptomics analysis is an advanced technology that can
describe the intracellular transcriptome in complex tissues. It profiles
and analyses datasets by single-cell RNA sequencing. Neurodegenerative
diseases are identified by the abnormal apoptosis of neurons in the
brain with few or no effective therapy strategies at present, which has
been a growing healthcare concern and brought a great burden to society.
The transcriptome of individual cells provides deep insights into
previously unforeseen cellular heterogeneity and gene expression
differences in neurodegenerative disorders. It detects multiple cell
subsets and functional changes during pathological progression, which
deepens the understanding of the molecular underpinnings and cellular
basis of neurodegenerative diseases. Furthermore, the transcriptome
analysis of immune cells shows the regulation of immune response.
Different subtypes of immune cells and their interaction are found to
contribute to disease progression. This finding enables the discovery of
novel targets and biomarkers for early diagnosis. In this review, we
emphasize the principles of the technology, and its recent progress in
the study of cellular heterogeneity and immune mechanisms in
neurodegenerative diseases. The application of single-cell
transcriptomics analysis in neurodegenerative disorders would help
explore the pathogenesis of these diseases and develop novel therapeutic
methods.
Lightweight Secure Message Transfer Protocol Based on ECC (Nist P-256) Internet of Things Equipped with Satellite Communications

Published: May 2023

With the expansion of Internet of Things (IoT) services and the use of
satellite communications, according to the regional or continental
extent of these services, the need for lightweight encryption has
increased. In satellite communications, due to long distances, there are
limitations in applying security, so heavy encryption algorithms such as
RSA[1](#fn-0002) cannot be trusted for security.
ECC[2](#fn-0003) using mathematical solutions and elliptic curve
discrete logarithm problems (ECDLP[3](#fn-0004)) can be considered
a lightweight algorithm in telecommunications. Here, we propose a new
strategy for secure IOT data communication between a satellite link and
a terrestrial link that uses the principles of ECC elliptic curve
cryptography and the NIST P-256 standard for key agreement and
encryption for transmitting messages over the satellite communication
platform.
