Published: December 2023

Abstract. The emergence of micromobility, exemplified by bike sharing and e-bike sharing systems, has ushered in a low-carbon, environmentally friendly, and sustainable revolution in urban transportation. This transformative shift addresses the "first and last mile" challenge and holds immense potential for urban mobility enhancement. Nevertheless, the existing literature predominantly investigates the spatiotemporal travel patterns and influencing factors of bike sharing and e-bike sharing systems in isolation, overlooking comparative analyses grounded in quantitative methodologies. In order to fill this gap, this study first compares and analysis their spatiotemporal travel patterns, which are measured by travel distance, travel time, and travel volume. A Multiscale Geoweighted Regression (MGWR) model was constructed using various data sources, such as Point of Interest (POI) data, metro station data, and bus stop data, to conduct a spatiotemporal correlation analysis of land use and public transport factors with the travel volume of the shared system. Our study centers on Manhattan, New York City, utilizing data from May 2022 for both bike sharing and e-bike sharing systems. The study analysis reveals that hourly trip volumes are higher for bike sharing than for e-bike sharing, exhibiting substantial spatial variation across different regions within the city. The MGWR model's findings suggest that educational facilities exert a negative influence on bike sharing in the northeast and on e-bike sharing trips in the central region, with this impact being more pronounced on weekends. Similarly, cultural facilities negatively affect the Central region's bike sharing system and the citywide e-bike sharing system, with a milder effect during weekends. Moreover, bus stops exhibit a significant negative impact on bike sharing and e-bike sharing at Chelsea Waterside Park (only weekdays), while displaying a positive influence on both systems during weekends. To validate the MGWR model's efficacy, we conducted a comparative analysis with a Geographically Weighted Regression (GWR) model. The results demonstrate that MGWR can be more effective in correlating and quantitatively explaining the effects of different factors on spatiotemporal travel patterns. In conclusion, this study furnishes valuable insights for optimizing urban infrastructure rebalancing strategies and advancing sustainable urban infrastructure development.

Abstract. Determining soil moisture remains an important issue in environmental, agricultural, and crop fields. The use of remote sensing data in the study of soil surface moisture has many benefits, such as: saving time, resources, and money, as well as monitoring soil condition (surface soil moisture). Based on point data from field measurements, can be used to obtain results of soil moisture. The importance of this study is highlighted by the useof spectral measurements and laboratory-determined moisture content of a variety of soils with different geographical conditions spread over three different natural zones, combined with satellite data. The purpose of this research is to determine and analyse surface soil moisture using Sentinel-2 satellite data and Spectro radiometric measurements. For this research area, four areas representative of forest steppe, steppe, and Gobi eco-regions of Mongolia were selected, field research was conducted, data were collected, and Sentinel-2 satellite data was processed and analysed. According to the results of the spectral reflectance measured during the field research, the high reflectance of the wet soil spectrum in the forest field, and the low reflectance of the spectrum representing the Gobi region, respectively, this create the possibility of studying soil moisture by spectral measurement and analysis. The relationship between the spectral reflectance of the red (665 nm) and near-violet (842 nm) light regions shows that the soil of the forest-steppe region is relatively moist compared to the soil of the Gobi region and that the Gobi soil is drier, and the field soil is drier, and these parameters are confirmed by laboratory analysis. A model developed from a linear relationship between field-measured spectrometer reflectance and laboratory-determined moisture provides a formula that can be used for regular monitoring of moisture content using the Normalized Difference Water Index (NDWI) estimated from satellite data. Surface soil moisture (%) = −44.133*NDWI − 11.553. The NDWI calculated from the spectroradiometer compared to the humidity determined in the laboratory had a linear correlation of R2=0.74 or 74%, and when comparing the humidity calculated from Sentinel-2, the agreement was high. In terms of space, the results calculated from satellite data show that the forest and steppe areas have relatively high humidity compared to the Gobi region, and the total area representing the Gobi region has a lower moisture content. Based on these results, it is considered that it is possible to continuously determine the amount of moisture from satellite data using NDWI (surface soil moisture) in a certain space-time range and use it for soil control and monitoring.

Published: December 2023

Abstract. Dungarpur, one of the most backward districts of India, is a predominantly tribal region of Rajasthan state. Ground water is the major source of drinking water in the region. High concentrations of Fluoride (F) and Iron (Fe) have been reported in the region which poses high risk of rampant water-borne diseases. This study evaluates the ground water quality for drinking purpose in terms of 10 hydro-geochemical and two biological parameters in context of causative factors like land use and geology of the region. The occurrence of water borne diseases in resident population has been examined in association with quality of drinking water and priority areas for policy intervention have been identified. Water samples have been collected from 173 drinking water sources and 346 households consuming water from the selected sources have been surveyed for prevalence of water borne diseases. Water quality surfaces have been mapped in terms of F, Total Dissolved Solids (TDS), Hardness, Fe, alkalinity, Faecal Coliform (FC), E. Coli, and Water Quality Index (WQI) computed on the basis of 10 geochemical parameters, using Inverse Distance Weighted (IDW) method. Results reveal that the north-eastern part comprising Aspur, Sabla and part of Sagwara tehsils predominantly has ‘very poor’ to ‘unsuitable’ water quality. The western part has excessive faecal contamination. Entire district has high levels of TDS and hardness, while excessive Fe and F occur in specific regions. Disease incidence closely corresponds to the geochemical and microbial composition of water. Higher values of WQI correspond with occurrence of Phyllites and Mica Schists.

Published: December 2023

Abstract. Irrigated agriculture requires extensive land areas and consumes high volumes of water. This study aims to determine and analyze the dynamics of irrigated croplands and their water consumption in Guanajuato State, located in the central region of Mexico. Guanajuato is among the Mexican states with the country's most considerable agricultural land extent, with more than half of its territory dedicated to agricultural activities. The work offers an innovative approach by adding official statistical information on irrigated agriculture crops and geospatial data for a considerable period. First, land use and cover change patterns were studied using a multidate land cover cartographic database. We observed some reduction in irrigated areas due to urban expansion; nevertheless, most irrigated regions remained stable over time. After that, we computed the areal evolutions of ten main crops and their associated water consumption. We observed a slight contraction of irrigated agriculture. However, the most notorious changes in water consumption are due to changes in the types of crops and agricultural intensification can burden water scarcity.

Published: December 2023

Abstract. Wind can impact pedestrian comfort. This comfort can be observed by integrating a 3D city model into the study area. However, little research has been done on the influence of different wind angles on pedestrian wind comfort and rarely on implementing 3D city models in the wind environment. Therefore, this study aims to fill the gap in using 3D city models to examine the effect of wind flow angles on pedestrian wind comfort. The Computational Fluid Dynamics (CFD) wind simulation environment presented in this study was constructed through the applied steady Reynolds-Average Navier-Stokes (RANS) with K-epsilon (k-ε) turbulence model. It is integrated with the standalone building model with a roof overhang structure represented in LoD2.3 of the CityGML standard. Three wind angles have been introduced to allow for variation in the analysis of pedestrian wind comfort: 0°, 15°, and 30° wind angles. Through the observation of multiple locations, which are directed beneath the roof overhang structure, the highest wind velocity is recorded in 0° wind angles compared to 15° and 30° wind angles. Thus, from these recorded values, pedestrian wind comfort is based on the Beaufort wind scale (BWS). The computed average recorded values show that 3.24 m/s corresponds to a wind angle of 0°, 2.761 m/s for 15°, and 2.415 m/s for 30°, which shows that all these values fall in BWS Scale 2. Thus, these areas experience a light breeze. However, the lowest value from a 30-degree environment presents the most reposeful surrounding.
HOW THE HUMAN NEEDS EVOLVING INTO SDGS – MIRACLE OF THE RIVERS
Authors: Altan O.
Published: December 2023

Abstract. Over 7000 years ago, great civilizations started by settlements around the great rivers of the Near East. One of them is the Area called Mesopotamia. The region is broadly defined to include now eastern Syria, south-eastern Turkey, and Iraq. In the narrow sense, Mesopotamia is between Euphrates and Tigris rivers. The world of mathematics and astronomy owes much to the Babylonians—for instance, the sexagesimal system for the calculation of time and angles, which is still practical because of the multiple divisibility of the number 60; the Greek day of 12 "double-hours"; and the zodiac and its signs. The region was the center of a culture whose influence extended throughout the Middle East and the Indus Valley, Fare East, Egypt, and the Mediterranean.In this paper, we will describe how different cultures ate influenced by the Mesopotamian civilization and their way of Life in harmony with Nature and, later, how we had to take care of our current needs in compliance with Nature.

Published: December 2023

Abstract. Recently, HD maps have various merits for achieving the highest level of self-localization accuracy, keeping track of the state of the road infrastructure and maintenance, and providing an indication if any repairs are required. Therefore, it is essential to keep the HD map up to date. However, the process of updating the HD map is exorbitant because the HD map is created using expensive sensor setups, and updating the map frequently via these setups will be costly. In this paper, a full pipeline is proposed for updating the HD map via a crowdsourced dataset that is collected with low-cost smartphone sensors. Furthermore, an Android application is developed and installed on a smartphone to collect the raw data. Once the dataset is collected from the area of interest, it will be uploaded automatically to the cloud server that is connected to the HD map database. Then, object detection, depth estimation, and matching algorithms are triggered on the cloud server to keep updating the HD map database. The positions of the detected objects from the crowdsourced dataset are estimated by using fused outputs of deep learning models and the Global navigation satellite system (GNSS) of a smartphone and then compared with the objects in the HD map through matching algorithms. The proposed model is considered the first comprehensive pipeline approach for updating HD maps with high a cost-effective and efficient solution.

Published: December 2023

Abstract. Several advancements are going with Unmanned Aerial Systems (UAS) with the addition of multiple sensors and simultaneous data acquisition to obtain detailed geo-data for various applications. However, simultaneous data acquisition with multiple sensors, namely camera, and LiDAR, will also result in possible discrepancies associated with them, and they need to be solved to use a reliable and accurate final product. Several errors can be associated with both camera and LiDAR datasets due to the different characteristics of the sensors and terrain conditions. This research paper aimed to minimize the errors between LiDAR and the image datasets simultaneously acquired with an Unmanned Aerial System (UAS) by implementing a hybrid adjustment approach with a criterion for the roughness and threshold angle between surface normals. The initial trajectory of the UAS, raw LiDAR measurements, and image observations were the inputs used for the hybrid adjustment. The hybrid adjustment workflow minimizes the discrepancies with a least-squares-based simultaneous adjustment for both LiDAR and image datasets. For the hybrid adjustment process, three types of correspondences were established, namely: between image pairs, overlapping LiDAR strips, and between Image tie points and LiDAR strips. For quality control, mean Cloud-to-Cloud distances (C2C) were compared between both LiDAR and camera point clouds before and after hybrid adjustment. The surface-level analysis of the results was also carried out to analyze the errors before and after hybrid adjustment at a surface level for different types of surfaces. The results showed that the alignment between the point clouds has significantly improved from the range of meters to a centimeter-level after implementing the hybrid adjustment process. The proposed hybrid adjustment workflow can be used in mapping applications where a centimeter-level accuracy is requested.
INDOOR POSITIONING AND NAVIGATION BASED ON QR CODE MAP
Authors: Liu R. K. , Zhang D. J.
Published: December 2023

Abstract. Solving the indoor positioning problem can effectively improve work and life efficiency. Outdoors, navigation and positioning mainly rely on satellites to provide global positioning and road network topology to constrain the direction of travel. Therefore, to achieve good indoor navigation and positioning, two things are needed: 1) continuous position acquisition and 2) an indoor road network. Since the indoor environment is relatively stable, the geodetic coordinates of key indoor nodes can be obtained in advance through measurement methods and control points can be set up. Inertial navigation is stable and autonomous, and when combined with control points, it can achieve stable position acquisition. QR codes are rich in information, low in cost, and easy to deploy. They can be used as nodes to construct an indoor road network or as control points. This study proposes an indoor road network map construction method that can achieve local accuracy and global consistency in large indoor scenes. In this indoor road network map, node information includes the position and posture of the QR code. When a machine passes through a node position, it can obtain its absolute position and direction in the geodetic coordinate system by taking a picture of the node’s QR code and combining it with IMU fusion positioning. Through map edge information, indoor navigation and path planning can be achieved.

Published: December 2023

Abstract. Autonomous driving relies on high accuracy point vector map, which was generated by the point cloud map, and pre-provides the vehicle preliminary road environment information. Lidar Odometry and Mapping (LOAM) has always been a promising research topic in the field of robotics, environment sensing, and currently autonomous driving. However, in certain urban environments like basement parking lot, tunnels, highways, or other similar settings, the geometric features are not clearly discernible. As a result, algorithms resembling the LOAM framework may encounter difficulties in accurately mapping these areas. The paper utilized relative low-cost LiDAR expecting to propose a state-of-the-art point cloud mapping/update scheme. We compared the GNSS-challenge area with straight line and loop area separately, simultaneously considered the DG, ICP, NDT matching algorithm for the low-cost mapping/update strategy. With the realistic experiment conduction, our result evaluated by point to point corresponding mean error and standard error. For the straight line environment, ICP has the fastest convergence in empirical cumulative distribution under 0.4 meters. For the loop scenario, point-to-point ICP still has the fastest convergence in empirical cumulative distribution under 0.22 meters. Yet both of them still suffer from the fault matching.

Published: December 2023

Abstract. The application of the INS/GNSS integrated system is widespread in vehicle navigation. However, in certain complex urban areas, achieving accurate positioning for autonomous vehicles at level 3 and beyond presents a challenge. Moreover, ensuring the continuous availability of the navigation system is crucial for maintaining vehicle safety under all circumstances. Consequently, the specifications of the Inertial Measurement Unit (IMU), which have a direct correlation with cost, dominate the performance of the navigation system in environments where GNSS signals are denied or challenging. To implement level 3 autonomous vehicles, a strategy based on redundant IMUs (RIMU) is employed to not only enhance accuracy and availability but reduce the overall cost of the navigation system. This research mainly focuses on the development of a robust autonomous vehicular navigation system by designing an integrated algorithm for the low-cost RIMU and GNSS receiver within the INS/GNSS integration scheme. The positioning performance is analyzed by using a reference system and a benchmark system in the open sky, GNSS challenging, and GNSS outage scenarios.

Published: December 2023

Abstract. In response to the rapid development of autonomous vehicles and the increasing demand for HD maps, the conventional mapping processes following HD maps guidelines require significant manpower and time resources. Therefore, we propose flexible procedures and methods for HD maps creation, aiming to reduce cost expenditure by employing diverse source of ground control point, sensor data collection, and mapping algorithm. This approach accelerates the production speed and capability of HD maps. In this study, we select Taiwan's National Highway No. 8 as the trial field for the elastic HD map construction method, and equipped with autonomous vehicle-grade GNSS, IMU, and LiDAR systems.We align the constructed-map data to the global coordinate system, in order to realize the concept of control point cloud map. To assess the assistance and correction capabilities of HD maps in autonomous vehicle navigation systems, we conduct accuracy evaluation through both direct and indirect methods, and analyse the strengths and weaknesses of each approach. The analysis result demonstrates that the elastic method-built HD maps not only meet the mapping accuracy requirements specified in the HD maps verification and validation guidelines, but also assist autonomous vehicles in realizing positioning, navigation, and timing with “where in lane” level (0.5 meter) accuracy.

Published: December 2023

Abstract. Traffic sign detection is an important part of autonomous driving technology, and it is also important to have a large-scale dataset applicable to Chinese traffic scenarios. The article proposes a text-based self-labelled traffic sign dataset which consists of 3153 images, of which 2903 images are used for training and 250 images are used for validation. And an improved YOLOv7 algorithm is provided that incorporates the BiFormer attention mechanism into the YOLOv7 network to enhance its ability to detect small objects. This approach has the advantage of improved accuracy but may increase runtime. To mitigate this problem, the improved YOLOv7 network undergoes model pruning to compress the model size and increase its speed. Experimental results show that the improved YOLOv7 network in this paper improves the average accuracy by 2.9% while maintaining almost the same speed as the original network. After testing, the model has a real-time effect and practical significance. In conclusion, the text-based self-annotated dataset and the improved YOLOv7 network proposed in this paper have important reference values for text-based traffic sign recognition in automatic driving assistance systems.

Published: December 2023

Abstract. Accumulation of plastic debris in water bodies has recently become a global concern, where the hotspots are being affected by a flow of toxic plastics from different sources. This study applied a science-based methodology for monitoring and assessment of macro plastic debris in the shoreline and sea surface of a pilot Egyptian Mediterranean site. Optical spectral of Sentinel-2 and Planet scope images were examined using a combination of different spectral bands with several indices and verified by the pixel-value classification method of Sentinel-2 images. Further, microwave remote sensing (Sentinel-2, SAR sensor) was analyzed to add more information to the optical study. Quantitative field measurements of marine debris were applied using UNEP/MAP metadata to support satellite results. This study found that 82% of beach accumulated materials were artificial polymers and that classification image was the most precise technique that reflects the real variety of different features. The overall accuracy of plastics detection and identification using remote sensing techniques reached about 70–80%.

Published: December 2023

Abstract. Virtual Reality (VR) lab components provide the opportunity to explore the efficacy of this technology on Geomatics education and lay the groundwork for the VR as an emerging education paradigm. Geomatics education at UF has been innovatively optimized towards a hybrid education system, with most of the curriculum taught using distance communication. Nevertheless, Geomatics teaching still involves intensive indoor and outdoor lab components. VR labs enable learning and practicing lab techniques as an alternative or supplement to live lab activities. These technically and physically demanding activities require intensive training on expensive lab equipment. The labs often go beyond allocated lab time and are susceptible to bad weather conditions. Using VR technology provides an integrated learning experience that mixes instructions with simulated physical activities, eliminating many limitations associated with lab instruction. In this study, we demonstrate the development of the total station device centring and levelling lab activity using the Meta Quest 2 Headset on the Unity Software Development Platform, as well as Unity’s XR Interaction Toolkit. Development challenges related to different setup components (e.g., bubble-level setup, effective gravity for editing tripod placement, component intractability) are presented. Among multiple challenges of using Unity for the development of an educational VR application, adjusting the functions of the XR Toolkit in order to get the desired outcomes stands as one of the largest difficulties. Unity’s physics is not intuitive for the intended purposes of this project, so multiple technical workarounds were required including the use of Unity’s UI (User Interface) features.

Published: December 2023

Abstract. The European Commission (EC), being the co-lead of the European Regional Group on Earth Observations (EuroGEO), is currently outlining an ecosystem that will interconnect European technologies, digital infrastructures and data and enable the implementation of policy-relevant use cases using shared standards. This ecosystem will in turn strengthen Europe’s contribution to GEOSS, which is the Global Earth Observation System of Systems. To evaluate and demonstrate the potential of this ecosystem, prioritization of use cases is necessary. This work presents a methodology for this prioritization, taking into consideration policy relevance, data and digital infrastructures and adherence to European approaches, principles and values. This methodology can also be used for identifying noteworthy research projects in the Earth observation (EO) domain that possess policy relevance and have the potential to be transformed into sustained and operational services beyond the funding period, focusing on research projects funded by Horizon 2020 (H2020) and Horizon Europe EU Framework Programmes for Research and Innovation. We applied this methodology to an H2020 project named “EuroGEO Showcases: Applications Powered by Europe (e-shape)”, composed of 37 pilots, and here we present the results. This process led to the identification of a priority pilot on solar energy potential assessment in urban areas, for which EC Knowledge Centre on Earth Observation (KCEO) will participate in co-design activities with ARMINES, the leader of this pilot. We finally present the pilot shortly and elaborate on the next steps.

Published: December 2023

Abstract. Map verification plays a crucial role in ensuring the accuracy and reliability of map data, which in turn establishes the foundation for map transparency. In China, the number of approved map inspections has been increasing annually, with a diverse range of map products being applied for inspection. Taking the example of the 'number of maps accepted for inspection' by the Ministry of Natural Resources of the People’s Republic of China, there has been a consistent upward trend in the number of accepted inspections. From 2017 to 2021, the average annual growth rate of accepted inspections exceeds 18.85%. Not only are new types, uses, and formats of map products emerging, but there is also an increase in the utilization of electronic global maps. However, challenges such as the inefficient information transfer during the inspection application process and the limited automation of technical inspections persist. Furthermore, issues related to the variability of inspection results based on individual experiences need to be addressed. To tackle these problems, this paper proposes a comprehensive technical framework for map verification based on the principles of "data sharing, business collaboration, and intelligent assistance". The objective is to establish a map verification service mechanism that promotes cross-departmental coordination and intelligent cooperation. Implementing this framework will facilitate the smooth operation of national map verification services and expedite the sharing and openness of geospatial data.

Published: December 2023

Abstract. Open Science is a catalyst for innovation. Across the Earth Observation value chain, from R&D to prototyping new products and development of commercial applications, openness can play an important role by promoting long-term sustainable, community-contributed science and technology. The FAIR principles provide essential support to implementing Open Science, by offering guidelines for how researchers can adapt their EO and Earth Science practice to enable that their work (taking place increasingly in the cloud) and results are discovered, accessed, used, and reproduced by others. The Open Science Data Catalogue (OSC) (https://opensciencedata.esa.int) is an ESA Open Science activity aiming to enhance the discoverability and use of the various scientific and value-added results (i.e. data, code, documentation) achieved in Earth System Science research activities funded by ESA EO. The OSC provides open access for the scientific community to geoscience products (based on EO data from ESA and non-ESA missions and other geospatial information and models) across the whole spectrum of Earth Science domains. The OSC adheres to FAIR principles and promotes reproducibility of scientific studies. The OSC makes use of various Open-Source geospatial technologies such as pycsw, PySTAC, and OpenLayers and tries to contribute back to these projects in terms of software and standardisation. This paper reviews the EO OSC architecture, technology stack, and illustrates how this tool can be used to discover and publish Earth System Science products from ESA activities. It also looks at future evolutions of the product and how it contributes to ESA’s EO Open Science and Innovation goals.
Introduire l’expérience mystique dans les notions de la politique
Authors: Chenavier Robert
Published: December 2023

Face à l’opposition du bien et du mal selon des méthodes irréligieuses ou idolâtriques, S. Weil propose une autre méthode, la mystique. L’expérience mystique provoque une transposition à un niveau supérieur de ce que pense la philosophe, notamment dans le domaine politique. Aussi cet article cherche-t-il à réfuter les façons erronées de fermer tout accès à la question de la relation entre mystique et politique.
La voie empruntée par la philosophe dans son analyse de la littérature aide à comprendre sa position dans le domaine politique, mais l’analyse de la « spiritualité spécifique » de la guerre révèle la difficulté de penser le rapport entre le spirituel et l’action.
L’issue à la difficulté rencontrée est de passer, « à force d'art », du côté du « rapport vrai » entre le règne de la nécessité et une aspiration inextinguible au Bien. Il convient, du côté de l’action, de réexaminer le « Projet d’une formation d’infirmières de première ligne ». Côté littéraire, Venise sauvée illustre cet effort pour manifester une vérité qu’il appartient au poète de présenter.
Agustín interpretado por Romano Guardini
Authors: Bissoli Lucia
Published: December 2023

En varios momentos de su desarrollo intelectual, Romano Guardini se interesó en el pensamiento de Agustín, impulsado tanto por inquietudes personales como por las provocaciones que le ofrecían los pensadores de su época. El pensador alemán, de hecho, presenta en sus textos un Agustín existencial que busca la respuesta para la realización de la propia vida y plantea esta cuestión a Dios. El texto está dividido en tres partes. En la primera parte se explica el enfoque de Guardini y su forma de estudiar los textos agustinianos. En particular, se ha analizado el vínculo entre este pensador y las reflexiones de Max Scheler, por asonancia, y las de Nietzsche, por contraste. La segunda parte del artículo es una explicación de la experiencia religiosa a partir del texto de Las Confesiones, por un lado, y de la obra guardiniana Anfang por otra. Por último, el texto se cierra con algunas observaciones críticas sobre la reflexión de Guardini, en particular respecto a su antropología y considerando las investigaciones de teólogos y filósofos, Massimo Borghesi sobre todo, que ya han tratado el mismo tema.
Descartes, Freud y Lacan: el pasaje al acto y la pesadilla
Authors: Arbaizar Gil Benito
Published: December 2023

Partiendo de la noción lacaniana de pasaje al acto se interpreta el proceso de la duda y los momentos clave de su superación en los términos de un pasaje al acto humano que dará lugar al cogito y un acto divino que dará lugar al orden inmutable de las verdades eternas. De ese modo se trata de explicar el modo en el que Descartes constituye el marco fantasmático de la ciencia. Si bien en el seguimiento del proceso de la duda el texto de referencia será Meditaciones metafísicas, se indica cómo en dicho proceso es reconocible el eco de una experiencia onírica decisiva que Descartes tuvo a los 23 años, experiencia que ayuda a comprender tanto el impacto de angustia que hay detrás del giro metafísico cartesiano como el reverso pre-subjetivo desde el cual acontece el despertar a la conciencia de sí que tiene lugar en el cogito. La vía preferente que se emplea en la interpretación llevada a cabo es la del psicoanálisis tal y como es desarrollado por Lacan.
Tratamiento farmacológico actual y futuro de la esteatosis hepática
Authors: Alonso Pedrol Núria , Julián Alagarda María Teresa
Published: December 2023

La enfermedad por hígado graso no alcohólico (NAFLD) representa la enfermedad hepática crónica más prevalente en el mundo. El tratamiento de los pacientes con NAFLD debe ir dirigido a disminuir el grado de inflamación hepática, evitar o retrasar la progresión de fibrosis hepática y lograr el control de los diferentes factores de riesgo relacionados con la enfermedad cardiometabólica, con el objetivo final de reducir la morbimortalidad. La piedra angular de su tratamiento es la pérdida de peso que se asocia a una mejoría de la histología hepática de forma proporcional a la magnitud de la pérdida ponderal. Se aconseja la adherencia a hábitos de vida cardiosaludables (dieta y ejercicio), siendo la dieta mediterránea la recomendada. En sujetos con NAFLD intervenidos de cirugía bariátrica, la pérdida ponderal se asocia a una disminución del riesgo cardiovascular (CV) y de los eventos adversos de causa hepática. En la actualidad, no existe ningún fármaco aprobado de forma específica para el tratamiento de la esteatohepatitis no alcohólica (NASH, del inglés non-alcoholic steatohepatitis).
Protocolos de la MAFLD (enfermedad hepática metabólica)
Authors: Mahulea Liliana , Escribano Pardo Daniel
Published: December 2023

Este artículo es una revisión de la bibliografía más reciente orientada hacia protocolos, algoritmos, guías clínicas y vías clínicas de la MAFLD. Una propuesta interesante de algoritmo para el diagnóstico y tratamiento es del grupo de trabajo sobre «Hígado graso no alcohólico» de la Sociedad Catalana de Digestología1. El primer paso es identificar a los pacientes con riesgo, a los que se les realiza un cribado para la detección de la NAFLD, mediante el uso de FLI (Fatty Liver Índex) y/o ecografía. En caso positivo, se continúa investigando la presencia de fibrosis, estratificando el riesgo en bajo y medio/alto. Según este, se realiza intervención (cambios de estilo de vida, control de las enfermedades asociadas) y reevaluación cada 2-3 años con analítica y marcadores de fibrosis, o, en el caso de riesgo moderado/alto, se recomienda proseguir con elastografía y posteriormente nos hacen unas recomendaciones para AP y hospital basadas en tratamiento de los factores de riesgo. Se realiza un resumen de las guías de práctica clínica publicadas hasta la fecha con tablas de resumen de las principales recomendaciones.

Dentro de los pacientes con diabetes mellitus tipo 2 (DM2) existen multitud de subpoblaciones, algunas de ellas muy susceptibles a presentar un mal control y con un elevado riesgo de hipoglucemias, tales como son los pacientes frágiles, con enfermedad renal o poshospitalización, muchos de los cuales precisarán ser tratados con insulina basal para su adecuado control. En relación con los pacientes frágiles, es muy importante detectar dicha condición, ya que la determinación de sus objetivos de control y su manejo terapéutico debe realizarse de un modo muy gradual, evitando al máximo la utilización de fármacos con elevado riesgo de provocar hipoglucemias. En este sentido, la insulina glargina 300 U/ml (Gla-300) es una gran elección ya que presenta un menor número de hipoglucemias con una eficacia similar a las insulinas basales de 1.ª generación. Otra situación que requiere un especial cuidado es la que se produce tras un alta hospitalaria en pacientes con DM2 que han requerido ser tratados con insulina, ya que en algunos casos esta podrá ser retirada, pero en otros será preciso mantenerla para alcanzar un adecuado control. La insulina Gla-300 posee estudios en los que se ha mostrado de gran utilidad en pacientes con DM2 mal controlados durante la hospitalización y tras recibir el alta. Por último, los pacientes con enfermedad renal crónica son muy susceptibles a presentar un mal control glucémico y un elevado riesgo de hipoglucemias, por lo que su manejo terapéutico debe realizarse con una gran precaución, de un modo similar al de los pacientes frágiles, siendo la insulina Gla-300 una alternativa eficaz y con un bajo riego de presentar hipoglucemias.

La hemoglobina glicada (HbA1c), hasta ahora patrón de oro para evaluar el control de la diabetes, presenta limitaciones en su uso y no refleja las excursiones glucémicas, la variabilidad glucémica (VG), ni los episodios de hipoglucemia o hiperglucemia. Desde hace años, se viene recomendando el uso de la monitorización continua de la glucemia (MCG) conjuntamente con la HbA1c, con el objetivo de evaluar el control glucémico y que seamos capaces de ajustar los tratamientos, sobre todo con insulina, basándonos en esos datos. El presente artículo describe la importancia de la variabilidad glucémica y repasa cómo interpretar el análisis del perfil AGP (perfil glucémico ambulatorio).

Authors: Sanju Nehad Laila
Published: December 2023

Travel and tourism is the world's largest and fastest-growing industry that benefits the environment, society, and economy by supporting businesses and improving supply chain efficiency. Reliable information is crucial for informed decision-making and positive experiences in this sector. Information technology has had a significant impact on the industry, leading to changes in organisational operations. Tourism companies use digital tools to promote sustainable tourism and achieve development goals. To stay competitive, businesses must embrace technology and adapt to new trends. Though there has been voluminous but fragmented research to cover the various aspects of the tourism information system by several researchers over the years, a big picture is still missing due to the dynamic changes in the technological aspects that reveal varied developments in the tourism industry. Hence, this paper reviews recent IT developments in tourism and hospitality, analysing research articles from the past decade. It aims to contribute to existing knowledge, provide insights into practical implementations, and suggest areas for further research in information systems in tourism.
