El presente estudio enfatiza la importancia de aplicar la pedagogía del amor y la ternura para desarrollar la identidad y autonomía de los niños. Esta pedagogía se centra en la afectividad durante el proceso de enseñanza-aprendizaje, adaptándose a las necesidades individuales de cada niño para asegurar un entorno en el que se sientan seguros, amados, respetados y escuchados. El objetivo principal fue proponer la pedagogía del amor y la ternura para el desarrollo del ámbito de identidad y autonomía en los niños de cuatro a cinco años de la Escuela de Educación Básica Yaguachi. Esta investigación utilizó un enfoque mixto para lograr una comprensión minuciosa del fenómeno estudiado, el enfoque cualitativo se aplicó a través de entrevistas a los docentes para entender cómo la pedagogía del amor y la ternura influye en el desarrollo de la capacidad de los niños para tomar decisiones y actuar de manera independiente. En cambio, el enfoque cuantitativo se implementa mediante una escala estimativa aplicada a los niños del nivel Inicial 2, lo que permitió evaluar su desenvolvimiento y comportamiento a través de la recolección y análisis de datos numéricos. Los resultados revelaron que los niños presentan dificultades en su identidad y autonomía, lo que ha generado problemas en su interacción social, ya que les cuesta tomar decisiones por sí mismos y en ocasiones dependen de los adultos. Se concluyó que es importante ofrecer un espacio que promueve la autoexpresión y el intercambio emocional. Se sugiere implementar actividades que incluyan momentos dedicados a la expresión de sentimientos y emociones a través de juegos, cuentos interactivos y ejercicios de reflexión.

Authors: Prieto Chama Abril Joselin
Published: January 2025

Las Infecciones del Sitio Quirúrgico (ISQ) son aquellas complicaciones que ocurren dentro de los primeros treinta días del procedimiento quirúrgico, involucrando la piel y el tejido profundo en el sitio de la incisión, siendo ésta la segunda causa de infección hospitalaria más frecuente según la OMS. Esta investigación determinó el nivel de conocimiento del personal de enfermería que labora en el quirófano con base en la guía de práctica clínica (GPC) para la prevención de infecciones del sitio quirúrgico en cirugías de traumatología y ortopedia. Participaron 44 personas pertenecientes al personal de enfermería que laboran en el área de quirófanos del Centro Médico Naval. (CEMENAV). El método de recolección de información se basó en la aplicación de una encuesta con preguntas demográficas (7) y preguntas de conocimiento (35). Se concluyó que, en el CEMENAV existe un nivel de conocimiento moderado respecto a la GPC para la prevención de las ISQ, recayendo en gran medida a la falta de capacitación del personal de enfermería, lo que implica una implementación necesaria de capacitaciones continuas para garantizar el cumplimiento de la GPC y reducir las ISQ.

Published: January 2025

Contexte. Une communication médecin-patient efficace a des effets positifs sur la santé des patients. En France, la formation initiale à la communication est modelée par chaque département de médecine générale (MG).
Objectif. Caractériser le ressenti des étudiants du diplôme d’études spécialisées (DES) de MG de Lille sur leur formation à la communication médecin-patient.
Méthode. Il s’agissait d’une étude qualitative portant sur des étudiants du DES de MG de Lille ayant effectué leur stage ambulatoire de premier niveau, interrogés par entretiens individuels semi-dirigés.
Résultats. Les étudiants s’appuyaient sur l’échange entre pairs pour s’améliorer et imaginaient l’intervention de professionnels non médicaux dans leur formation facultaire. Ils se rassuraient en pratique par la présence de leur maitre de stage, mais souhaitaient plus d’autonomie. Ils souhaitaient améliorer la supervision directe par l’utilisation de la vidéo en consultation. Pour eux, le retour de pratique était primordial notamment celui des patients. La confiance en soi a été l’élément central, dépendante de multiples facteurs personnels comme expérientiels.
Conclusion. Cette étude suggère l’importance qu’accorderaient les étudiants à la formation à la communication. Ils ont exposé des voies d’amélioration pour atteindre le niveau attendu et se sont questionnés sur une formation plus précoce.

Démence et devenir
La démence affecte gravement l’espérance de vie et l’autonomie. Cette étude avait pour objectif de quantifier les durées de vie et les délais avant admission en maison de retraite après un diagnostic de démence. Une revue systématique avec méta-analyse a inclus 261 études (5,5 millions de patients pour la survie et 353 000 pour les admissions en maison de retraite) publiées jusqu’en 2024. Les critères d’inclusion ont sélectionné des études longitudinales sur au moins 150 participants, avec un suivi minimal d’un an. L’espérance de vie médiane après un diagnostic de démence variait selon l’âge, le sexe et le type de démence : pour les hommes de 6,5 ans (à 60 ans) à 2,2 ans (à 85 ans) et pour les femmes de 8,9 ans (à 60 ans) à 4,5 ans (à 85 ans). Dans l’ensemble, les femmes ont eu une survie plus courte que les hommes, avec une différence moyenne de 4,1 ans (IC95 = 2,1-6,1), ce qui s’explique par l’âge plus avancé au moment du diagnostic chez les femmes. Environ un tiers de la durée de vie restante était passé en maison de retraite. L’admission médiane survenait après 3,3 ans (intervalle interquartile de 1,9 à 4 ans). À 5 ans, 57 % des patients avaient été admis, contre 13 % la première année. Les patients atteints de la maladie d’Alzheimer vivaient en moyenne 1,4 an de plus que ceux avec d’autres démences. La survie était également plus longue en Asie qu’en Europe ou aux États-Unis. Ces résultats soulignent l’importance d’une approche personnalisée pour le pronostic et la planification des soins, en tenant compte des caractéristiques cliniques, sociales et géographiques.

Clay dispersed in polar or non-polar liquids has various industrial uses. In the petroleum industry, clay suspended in oil-based mud is used in drilling sensitive formations. In crude oil refining, clay serves as catalysts in dehydrating ethanol and for other purposes. Clay stability in fluids is critical, necessitating deployment of additives to maintain stability. It is speculated that some nanoparticles have the potential to stabilize clays in fluids. This work therefore focuses on identifying types of nanoparticles that can promote clay stability in polar and non-polar liquids. Nine kinds of nanoparticles were investigated in vertical columns of ethanol and diesel containing Montmorillonite clay, and settled volumes of clay were plotted against time. Results show that oxides of aluminum and zinc nanoparticles promote clay instability in organic fluids while oxides of magnesium, iron, nickel, tin, zirconium and silicon have the tendency to enhance clay stability in polar and non-polar liquids.
Best operation strategies for piezoelectric vibration energy harvesters. III. Application to controllable inductance and capacitive loads
Authors:   Faculté des Sciences et Technologies, Université de Lorraine, Campus Victor Grignard, 54500 Vandoeuvre–lès–Nancy, France, BADESCU VIOREL
Published: January 2025

A general scheme of controlling the operation of piezoelectric vibration energy harvesters is proposed. When the load consists of a resistor and a controllable inductance, the maximum harvested energy depends on the value of the load resistance. For resistances much smaller than the resonance value most energy is harvested in the first cycle while the next cycles contribute a small amount of energy. For large number of cycles, the inductance may be used as a control when the load resistance is smaller than the resonance value provided its interval of variation is large enough. When the resistance equals the resonance value it is not recommended to use the inductance as a control. When the load consists of a controllable capacitor, the optimal capacitance value is constant and equals the smallest allowed value. The capacitance should be large enough to store the energy needed by the user during a limited number of cycles of the vibratory energy sources. General conclusions: (i) he maximum harvesting performance is obtained when the control parameters are constant or have a bang-bang-type time evolution; (ii) the number of cycles used for optimization is an important design parameter, especially in case of storing energy in capacitors; (iii) the most suitable applications are those which may be powered by using the energy harvested from a single cycle.

Nowadays the effects of the climate change on the environment and on the quality of our life become more and more obvious. Various studies pointed out the necessity to limit the global temperature increase below 1.5°C compared with pre-industrial levels. It is well known that a large part of greenhouse gas emissions is generated by the production of electricity and heat using fossil fuels. For this reason, an obvious measure to avoid the impacts of climate change is the utilisation of clean sources of energy to produce electricity. In the marine environment, there are various sources of renewable energy, and the exploitation of offshore wind energy is a successful example. The evaluations regarding the wind power potential in the Black Sea indicate that there are areas where the exploitation of wind energy would be effective, such as the Romanian nearshore. Also, the use of hybrid systems could make efficient also the exploitation of the wave energy if we take into account the high potential of certain seasons. Considering the above mentioned aspects, an analysis of the energy potential of the wind and waves in the Black Sea is made in this study based on some existing works, as well as on recent results. Aspects regarding the effect of the climate change on these resources in the future will also be discussed, under various scenarios, such as RCP4.5 or RCP8.5. These results are of interest to various stakeholders interested in investing in the exploitation of the renewable resources existing in the Black Sea and also for coastal protection.
Metallothermal power plant
Authors:   SIM Doctoral School, PhD student National University for Science and Technology Politehnica Bucureşti, Splaiul Independenţei 313, Bucharest, Romania, COMAN TUDOR ADRIAN
Published: January 2025

Metallothermal power plants represent a proposal to obtain less polluting and cheaper thermoelectric energy, simultaneously with obtaining complementary metallurgical products (alloys, laminates, refractory/abrasive materials alice, powders, etc.). The thermal power plant uses a single primary energy source, namely the chemical energy potentially existing in a new type of fuel „metallothermal fuel”. This is a thermitic fuel that, by reacting thermally, drastically reduces the production of residues and more than 100 times the release of polluting gases (CO2, NOx, H2S, SO2, SO3 etc.).

Published: January 2025

Cities are dynamic systems that require continuous adaptation of sustainable mobility offers. Transitways, with dedicated infrastructure physically separated from other vehicle traffic, are considered solutions for increasing the attractiveness of public transport in high-density urban areas. However, the effects of the fragmentation caused in urban areas by transitways are insufficiently analysed. Mainly, the effects on the performance of freight vehicles in last-mile distribution are usually not assessed in the evaluation of the introduction of a new transitway. In this framework, the paper proposes a method for evaluating the influence of introducing a transitway on freight vehicle performance in last mile distribution. An efficient algorithm to search for optimal distribution itineraries is presented. The method is exemplified for urban distribution in a fragmented area of Bucharest by introducing a transitway. For the new setting in which road traffic is channelised due to the fragmentation of the urban area by the transitway, the road traffic network is formalised and the itineraries for goods distribution to a set of six convenience stores are deter-mined. The presented method argues the necessity of an integrative analysis of all the consequences of introducing dedicated transitways. In addition, the method is useful in evaluating the effects of introducing one-way traffic on road networks in congested urban areas on city logistic performance

The paper focuses on the development of a robotic solution for cancer treatment. Liver cancer and especially hepatocellular carcinoma is one of the deadliest causes of death worldwide. Even more, liver cancer leads to more than half of the metastatic pancreatic cancers. Its treatment depends on the tumor staging and other comorbidities of the patient, and if the health condition is poor, minimally invasive procedures are preferred. The ProHep-LCT parallel robotic system has been developed for the minimally invasive treatment of cancer liver using various approaches: brachytherapy, radiofrequency ablation or intra-tumoral drug release, all of which requiring an accurate needle placement. ProHep LCT has consists of two robots: one for tumor visualization using the intraoperative ultrasound technique and the other to deliver the targeted treatment. A research method regarding the onsite placement accuracy of the two modules of the ProHep-LCT using a commercial tracking system is proposed in the paper, to assess its usability for the medical task.

The aim of this article is to assess the renewable energy potential (solar and wind) of some representative water bodies for the southern part of Romania, more precisely the lakes Izbiceni, Razim, and Frasinet. As a first step, based on 20 years of ERA5 data (January 2003-December 2022), the monthly average distribution of some important parameters, such as the wind speed, solar irradiance and evaporation, was represented. In the case of the wind speed, the local resources were evaluated for a reference height of 100 m, since this is the level where most of the commercial onshore and offshore wind turbines operate. In this case, the Razim Lake presents a higher wind potential, which can go up to 7 m/s during the wintertime, comparing to 5.5 m/s expected from the Frasinet dam corresponding to the same time interval. This aspect is also reflected by the performances of the Siemens SWT 3.6-120 wind turbine that can provide a maximum power of 0.95 MWh/year in the case of the Razim Lake. In terms of the solar irradiance, there are slight differences between the considered sites, being noticed values in the range 52-277 W/m2 . For these lakes, the water body was gradually covered with floating solar panels, the proposed scenarios involving case studies that go from 10 to 30%. Besides the electricity production, it was found that a solar project can significantly reduce the water evaporation, being associated to a maximum water volume of 15 x 106 m3 (Razim Lake, 30% scenario). Finally, we can mention that a solar/wind project can be successfully implemented in most of the Romanian lakes, especially on the ones associated with the agricultural areas where the water scarcity may intensify in the near future due to climate change

For quite some time there has been a permanent interest in environmental monitoring. A special attention and a greater effort is necessary in the case of monitoring wild natural areas. The problems raised in this context are multiple and diversified, from the choice of identification algorithms to the actual implementation on the ground. In this work, the objective is to estimate as much as possible the required effort and the costs of such monitoring based on acoustic sensors. We review the already established solutions and analyze the solution previously proposed by the authors. A cost assessment is discussed, then the issues involved in remote control are discussed. Accuracy, robustness and reliability are also addressed.

This paper addresses a critical issue in VLSI chip design, specifically the integration of hardware security techniques. It introduces an improved algorithm for the efficient VLSI implementation of Type IV Discrete Sine Transform (DST-IV) using short quasi-band correlation structures. The proposed algorithm is restructured to facilitate the incorporation of key hardware security techniques with low overheads. This integration ensures the security and integrity of the VLSI implementation while maintaining high performance. By leveraging the regular and modular structure of the quasi-band correlation, the architecture aligns with the principles of systolic array architecture, offering advantages in speed and hardware complexity. The proposed method achieves a secure, high-speed, and low-complexity VLSI implementation, making it a robust solution for modern hardware design challenges

The paper synthesizes existing research on contamination and associated risks from industrial activities at the Poșta-Rât site in Turda, Cluj, Romania. Located in an industrial district, the site was contaminated with hazardous substances, including organochlorine pesticide like hexachlorocyclohexane (HCH), dichlorodiphenyltrichloroethane (DDT), and dangerous heavy metals (HM), due to uncontrolled dumping of lindane waste between 1954 and 1983. Recent studies reveal significant HCH contamination up to 70 cm deep and high levels of Zinc (Zn), Lead (Pb), Copper (Cu), Mercury (Hg), and Arsenic (As), far exceeding acceptable limits. The research highlights extreme organochlorine pesticide pollution and bioaccumulative heavy metals, emphasizing the urgent need for remediation and continuous monitoring to mitigate the ecological and health risks in this heavily polluted area.
Brazilian Portuguese Version of Intrinsic Motivation Inventory (IMI-Teq Br): Towards a Digital Well-Being Culture in Brazil
Authors: Nunes Caio , Darin Ticianne
Published: January 2025

Self-determination theory (SDT), a foundational psychological framework, has emerged as a pivotal lens through which to understand the dynamics of human-computer interaction (HCI) and Games User Research (GUR). Central to SDT is the conceptualization of intrinsic motivation, characterized by voluntary behaviors arising fro personal interest. An established method for assessing intrinsic motivation across various contexts is the employment of the Intrinsic Motivation Inventory (IMI). This study presents a meticulous translation and cross-cultural adaptation of the 22-item version of IMI, known as the Task Evaluation Questionnaire, into Brazilian Portuguese (IMI Teq Br). The process adhered to the comprehensive methodology outlined by Beaton, encompassing Translation, Synthesis, Back-translation, Expert Committee review, and Pre-testing phases. Statistical analyses, including Student’s T-test for independent samples, Exploratory Factor Analysis (EFA), and Confirmatory Factor Analysis (CFA), were conducted to ensure the validity and reliability of the translated instrument. Our findings corroborate the robustness of the adapted questionnaire, affirming its suitability for use within the Brazilian Portuguese-speaking context. This paper meticulously delineates the adaptation process and resultant statistical outcomes, offering insights into the significance of IMI Teq Br for engagement and motivation research grounded in SDT principles. Additionally, we thorougly discuss the challenges inherent to this context in Brazil, providing valuable considerations for future endeavors.

La Ministre Onkelinx a demandé au Centre fédéral d’expertise des soins de santé (KCE) de lui fournir un avis scientifique sur la programmation et le financement de l’IRM. Les données disponibles n’ont pas permis au KCE de se prononcer de manière scientifique sur le nombre d’appareils nécessaires (programmation). Par contre, il a étudié l’évolution de l’utilisation et du coût de cette technique d’imagerie médicale. Il en ressort que les appareils à Résonance Magnétique sont relativement trop peu utilisés en Belgique par rapport aux CT-Scanner. Pour favoriser la substitution entre ces deux techniques d’imagerie, le KCE recommande un assouplissement ou une suppression de la programmation IRM, en combinaison avec des mesures de financement susceptibles de maintenir le budget sous contrôle.

Het Federaal Kenniscentrum voor de Gezondheidszorg (KCE) onderzocht de werkzaamheid van de behandelingen met en zonder medicatie bij de ziekte van Alzheimer. Het stelde vast dat de enige interventie waarbij een belangrijk uitstel van de opname in een tehuis werd aangetoond, bestaat uit een professionele en langdurige ondersteuning van de mantelzorger van de patiënt. Het potentiële effect van deze niet-medicamenteuze interventie blijkt groter te zijn dan wat met de huidige geneesmiddelen kon worden aangetoond. Het KCE raadt verder ook aan om het gebruik van antipsychotica bij Alzheimer patiënten zoveel mogelijk te beperken omdat dit gebruik gepaard gaat met een hoger sterftecijfer
Evaluation rapide des implants inter-épineux et des vis pédiculaires pour la stabilisation dynamique de la colonne vertébrale lombaire

Published: January 2025

A la demande de l’INAMI, le Centre fédéral d’expertise des soins de santé (KCE) a mené une étude sur deux nouvelles techniques de stabilisation dynamique de la colonne lombaire : les implants inter-épineux et les vis pédiculaires. En Belgique, ces technologies sont déjà d’application dans plus de 50 hôpitaux. Leur objectif est d’éviter une chirurgie du dos classique, plus lourde et définitive. Il existe peu de preuves scientifiques démontrant que ces techniques sont sûres et qu’elles améliorent la situation du patient à long terme. C’est pourquoi le KCE ne recommande pas leur remboursement.

Het Federaal Kenniscentrum voor de Gezondheidszorg (KCE) ontwikkelde samen met het Wetenschappelijk Instituut Volksgezondheid (WIV) en het RIZIV een prototype van een meetsysteem om de performantie van de Belgische gezondheidszorg te meten. Een eerste oefening toonde aan dat een dergelijke meting een haalbare kaart is, als er aan een aantal voorwaarden voldaan wordt, zoals een goede samenwerking tussen de betrokken administraties en een betere beschikbaarheid van de gezondheidsdata. Zo zijn er nog steeds geen recente nationale gegevens over de sterfteoorzaken. Uit de voorlopige metingen lijkt de Belgische zorg goed toegankelijk te zijn. De Belgische preventieve zorg behaalt positieve punten op het vlak van vaccinatie, maar er wordt nog onvoldoende op bepaalde types van kanker (bvb borst -of baarmoederhalskanker) gescreend, met bovendien een groot verschil tussen de regios. Andere punten roepen dan weer vragen op: het hoge aantal baarmoederverwijderingen, een toename van de keizersneden en een hoge blootstelling aan medische straling. Omdat het hier gaat om een pilootstudie moeten de resultaten ervan (tabel 2, p11) wel met de nodige voorzichtigheid worden geïnterpreteerd en gebruikt. Een eerste volledig rapport zal tegen eind 2012 uitgewerkt worden.
Kwaliteitscriteria voor stageplaatsen van kandidaat-huisartsen en kandidaat-specialisten

Om een bekwame huisarts of specialist te worden is een goede praktische vorming (of stage) onontbeerlijk. In België wordt de kwaliteit van de stageplaatsen voor artsen niet optimaal opgevolgd. Stageplaatsen moeten weliswaar worden erkend door de overheid, maar de erkenning wordt bijna altijd automatisch verlengd en, zelfs als er zich problemen voordoen, zelden ingetrokken. De Hoge Raad van geneesheren-specialisten en huisartsen (HR) is verantwoordelijk voor de erkenning van de stageplaatsen. Het bureau van de HR vroeg het Federaal Kenniscentrum voor de Gezondheidszorg (KCE) te onderzoeken hoe de kwaliteit van de stageplaatsen objectief zou kunnen worden gemeten. Het KCE pleit voor de aanpassing van de kwaliteitscriteria en voor controles van stageplaatsen door een onafhankelijke instantie. Voor dit project werkte het KCE samen met Universiteit Antwerpen (UA) en de Université catholique de Louvain (UCL) .

Bewaking op afstand van patiënten met geïmplanteerde defibrillatoren. Evaluatie van de technologie en breder regelgevend kader.
Authors: Vinck Imgard , Stroobandt Serge , Gerkens Sophie , De Laet Chris
Published: January 2025

Het Federaal Kenniscentrum voor de Gezondheidszorg (KCE) wierp een kritische blik op een nieuwe techniek: de medische zorgverlening op afstand. Als voorbeeld nam het de bewaking op afstand van patiënten met een ingeplante hartdefibrillator. De meerwaarde en de veiligheid zijn vandaag nog niet echt aangetoond, waardoor het KCE terugbetaling nog niet aanbeveelt. Dit kan mogelijk herzien worden als de momenteel lopende studies overtuigender bewijs leveren. Hoe dan ook, een denkoefening over de terugbetaling van de techniek en de juridische omkadering is op korte termijn nodig.

Depuis plusieurs années, de nouveaux médicaments sont disponibles pour traiter l'hépatite B chronique. Le coût de ce traitement s’élève à environ 5 000 euros par patient et par an. Les décideurs ont demandé au Centre fédéral d’expertise des soins de santé (KCE) d’identifier quels groupes de patients sont susceptibles de bénéficier le plus de ce traitement, et à quel prix. Le KCE conclut que le bénéfice par euro dépensé est maximal lorsque le traitement est appliqué à un stade avancé de la maladie, à savoir le stade de la cirrhose du foie. Les calculs effectués par le KCE sont basés sur une étude originale de la progression et des coûts de la maladie, menée en collaboration avec un grand nombre d’hépatologues
Transcatheter aortakunstklep implantatie (TAVI)
Authors: Neyt Mattias , Van Brabandt Hans , Van de Sande Stefaan , Devriese Stephan
Published: January 2025

De percutane aortaklep is een kunstklep die ingebracht kan worden via een slagader in de lies. Ze is bedoeld voor mensen voor wie een klassieke operatie te riskant of onmogelijk is. In 2008 adviseerde het Federaal Kenniscentrum voor de Gezondheidszorg (KCE) om deze ingreep niet terug te betalen. Er waren twijfels over de veiligheid: de toen beschikbare gegevens suggereerden na de ingreep een hogere sterfte dan na een openhartoperatie. Bovendien is de ingreep bijna tweemaal zo duur. De ziekteverzekering volgde het advies van het KCE, wat zorgde voor heftige reacties in de pers. Onlangs werden de resultaten van een recente Amerikaanse klinische studie bekendgemaakt. Op basis hiervan adviseert het KCE nu om de ingreep terug te betalen voor een beperkte goed afgelijnde groep patiënten. Het gaat om mensen bij wie de klassieke operatie onmogelijk is om anatomische redenen, omdat ze bvb littekens hebben opgelopen door vroegere bestraling in de hartstreek of na vorige hartoperaties. Het gaat jaarlijks om 25 à 30 mensen, ongeveer 10% van iedereen die vandaag een percutane hartklep ingeplant krijgt. Voor patiënten die nog de klassieke operatie kunnen ondergaan, of die te ziek zijn om nog een substantieel voordeel te kunnen halen uit een TAVI ingreep, beveelt het KCE de terugbetaling niet aan.
