Published: December 2021

In vanadium redox flow battery (VRFB), the active area for charge-discharge plays an important role on the optimization of the system. In this work, the optimum flow rate and current density of Nafion 117 membranes were examined and compared using 5cm2 and 25cm2 size of interdigitated flow field to operate VRFB at maximum efficiencies and discharge capacity. During discharge, flow field 25cm2 showed the highest discharge capacity of 367.5mAh at 10mAcm-2 as compared to 5cm2 flow filed which gave 221.9mAh. For battery efficiencies, three different parameters showed significant effects on different size of interdigitated flow field. 25 cm2 size of interdigitated flow field gave higher efficiencies than 5.0 cm2 up to 98%. This research offers fundamental understandings that bigger active area is needed to fully utilize the performance of VRFB.

Published: December 2021

The Magnus effect and its evolution have greatly affected the aerospace industry over the past century to date. Nevertheless, cylinder embedment onto a flat plate offers a new discovery that is yet to be investigated, specifically whether the concept could enhance the aerodynamic properties of the flat plate following the Magnus effect momentum injection. Over the past decade, the use of a rotating cylinder on an aerofoil has existed from past researches studies where the embedment has significantly increased in its aerodynamic performance better than the one without Magnus application. However, it would be hard to achieve experimental-wise as an accurate measurement and fabrication would be needed to have the same resulting effects. Here, most of the researchers would not focus deeply on the placement of the cylinder as this may increase their fabrication and testing complications. Therefore, the current study delineates the use of flat plate as the foundation design to encounter the arise matter by reducing its complication yet easy to manufacture experimentally. In this work, the model output was evaluated by using ANSYS WORKBENCH 2019 software to simulate two-dimensional flow analysis for the rotational velocities of 500 RPM and 1000 RPM, respectively. This was done for different Reynolds numbers ranging from 4.56E+05 to 2.74E+06 which implicitly implied with free stream velocities varying from 5 m/s to 30 m/s for different angles of attack between 0 to 20 degrees. Prior to developing the best model embedment, the mesh independency test was validated with an error of less than 1%. The study resulted in a remarkable trend that was noticeably up to 32% (500 RPM) and 76% (1000 RPM) better in compared to the one without momentum injection. Similarly, the high recovery led to a tremendously lower of 51% (500 RPM) and 99% (1000 RPM), respectively. In sum, these findings generated a stall angle delay of up to 26% (500 RPM) and 78% (1000 RPM) accordingly.
A CFD Analysis of Decommissioned Oil Platforms Jackets on the Brazilian Coast
Authors: Fernando Rodrigues Gonzalez  , Roger Matsumoto Moreira
Published: December 2021

Every facility reaches the last phase in its life cycle, which is decommissioning. Since the last decade, this subject has been gaining importance in Brazil’s offshore oil and gas companies. For jacket type rigs, one of the methods widely applied after idling the production is the conversion of these structures into artificial reefs (ARs). There are several critical aspects for choosing the best strategy for cutting and sinking a platform jacket, ensuring the success of an AR from a biological point of view. One of them is the influence of marine currents and their fluid-structure interaction which, by maximizing local upwelling and back vortex effects, favours the growth of aggregated flora and fauna. This study consists in the application of computational fluid dynamics (CFD) techniques for studying the marine flow around a disassembled and sunk jacket in the seabed for the purpose of converting it into an artificial reef. An FVM (Finite Volume Method) from a commercial software (most recent version of ANSYS FLUENT®) is applied with the upwind scheme. A k-ε turbulence model on steady state is chosen. Field data about Brazilian coastal currents are collected and analysed from the amount of information available on a Brazilian Navy's meteoceanographic program. Next, different combinations of cutting and sinking a jacket are studied, always keeping a minimum 55m free water column. The objective is to verify where the formation of local upwelling regions - that is, where the vertical velocity component reaches values equal or greater than 10% of the magnitude of the free flow velocity - is more significant, without decreasing back eddy formation. It is observed that the dismemberment of the jacket with the positioning of its parts in an increasing height sequence in the direction of the prevailing current is favourable to generate local upwelling while tipping the structure at 90° to the prevailing current results in the most voluminous back eddy region.
Aerodynamic Pressure Mapping Technique from CFD to FEM Model of N219 Winglet

Published: December 2021

Due to relatively complex geometry of N219 winglets, CFD simulations have to be conducted to predict the aerodynamic load by the structure in some critical flight conditions. Since the aerodynamic CFD model is not the same as the finite element model of the structure, there is a need to accurately transform the load data between the two models. This paper discusses a simple alternative technique to map pressure distribution from the mesh or face zone of a CFD simulation to an FEM model using a Matlab based in-house code program. The technique focuses on how an FEM shell element has same pressure value with its nearest CFD element. Although the cumulative forces sometimes give different result, the pressure distribution is highly accurate, moreover when the FEM model has smoother elements. Validation has been conducted by comparing with other pressure mapping technique of a commercial software Patran. The results show a good agreement where the present technique provide a more accurate result especially for the critical biggest load among the cumulative forces in the three-dimensional direction. The proposed technique is currently suitable to evaluate loading characteristics of semi monocoque structures. A further treatment of the technique for other types of structure is currently under development.

Published: December 2021

Background: In South Korea, women aged 66 years are eligible for complimentary bone mineral density (BMD) screening via the National Screening Program for Transitional Ages. We aimed to evaluate the 10-year fracture risk in women receiving BMD screening between January 2008 and December 2015.Methods: BMD was classified as normal (T-score ≥–1.0 standard deviation [SD]), osteopenia (T-score <–1.0 SD and >–2.5 SD), and osteoporosis (T score ≤–2.5 SD) from dual-energy X-ray absorptiometry. Follow-up continued from the screening date until a diagnosis for clinical fragility fracture (including sites of the vertebrae, hip, pelvis, clavicle, humerus, forearm, wrist, lower leg, and ankle), censored at the earliest date of trauma, death, or December 2017; fracture was ascertained using diagnostic codes from the National Health Insurance Service database. A multivariable Cox proportional hazard model was used to estimate hazard ratios (HRs) and 95% confidence intervals (CIs) for the risk of fracture in women with osteopenia or osteoporosis relative to women with normal BMD.Results: Among the 271,197 women screened, 44.0% had osteopenia and 35.2% had osteoporosis. The 10 year cumulative incidence of fragility fractures was 31.1%, 37.5%, and 44.3% in women with normal BMD, osteopenia, and osteoporosis, respectively. Fracture risk was higher in women with osteopenia (HR, 1.31; 95% CI, 1.28 to 1.34) and osteoporosis (HR, 1.68; 95% CI, 1.64 to 1.72) than in women with normal BMD.Conclusion: Women with osteopenia and women with osteoporosis, identified by the national BMD screening program, demonstrated a substantially elevated risk of fracture.

Characterization of an Instrument Model for Exoplanet Transit Spectrum Estimation through Wide-scale Analysis on HST Data
Authors: Huber-Feely Noah , Swain Mark R. , Roudier Gael , Estrela Raissa
Published: December 2021

Instrument models (IMs) enable the reduction of systematic error in transit spectroscopy light-curve data, but, since the model formulation can influence the estimation of science model parameters, characterization of the instrument model effects is crucial to the interpretation of the reduced data. We analyze a simple instrument model and assess its validity and performance across Hubble WFC3 and STIS instruments. Over a large, n = 63, sample of observed targets, a Markov chain Monte Carlo sampler computes the parent distribution of each instrument model parameter. Possible parent distribution functions are then fit and tested against the empirical IM distribution. Correlation and other analyses are then performed to find IM relationships. The model is shown to perform well across the two instruments and three filters analyzed and, further, the Student’s t distribution is shown to closely fit the empirical parent distribution of IM parameters and the Gaussian distribution is shown to poorly model the observed distribution. This parent distribution can be used in the MCMC prior fitting and demonstrates IM consistency for wide-scale atmospheric analysis using this model. Finally, we propose a simple metric based on light-curve residuals to determine model performance, and we demonstrate its ability to determine whether a derived spectrum under this IM is high quality and robust.

Purpose: The purpose of this study was to determine if somatic mutations are associated with clinical and pathologic outcomes in patients with borderline resectable pancreatic cancer (BRPC) or locally advanced pancreatic cancer (LAPC) who were treated with neoadjuvant chemotherapy and stereotactic body radiotherapy (SBRT). Materials and Methods: Patients treated with neoadjuvant chemotherapy and SBRT followed by surgical resection from August 2016 to January 2019 and who underwent next generation sequencing of their primary tumor were included in the study. Next-generation sequencing was performed either in-house with a Solid Tumor Panel or with FoundationOne CDx. Univariate (UVA) and multivariable analyses (MVA) were performed to determine associations between somatic mutations and pathologic and clinical outcomes. Results: Thirty-five patients were included in the study. Chemotherapy consisted of modified FOLFIRINOX, gemcitabine and nab-paclitaxel, or gemcitabine and capecitabine. Patients were treated with SBRT in 33 Gy in 5 fractions. On UVA and MVA, tumors with KRAS G12V mutation demonstrated better pathologic tumor regression grade (TRG) to neoadjuvant therapy when compared to tumors with other KRAS mutations (odds ratio = 0.087; 95% confidence interval [CI], 0.009–0.860; p = 0.036). On UVA and MVA, mutations in NOTCH1/2 were associated with worse overall survival (hazard ratio [HR] = 4.15; 95% CI, 1.57–10.95; p = 0.004) and progression-free survival (HR = 3.61; 95% CI, 1.41–9.28; p = 0.008). On UVA, only mutations in NOTCH1/2 were associated with inferior distant metastasis-free survival (HR = 3.38; 95% CI, 1.25–9.16; p = 0.017). Conclusion: In BRPC and LAPC, the KRAS G12V mutation was associated with better TRG following chemotherapy and SBRT. Additionally, NOTCH1/2 mutations were associated with worse overall survival, distant metastasis-free survival, and progression-free survival.

In our study, FISH mapping using 18S-5.8S-25S rDNA and 5S rDNA sequences was performed for the first time onOphrys tenthrediniferaWilldenow, 1805,Serapias vomeracea(Burman f., 1770) Briquet, 1910 andHimantoglossum hircinum(Linnaeus, 1753) Sprengel, 1826. A detailed study was also performed onO. tenthrediniferausing Giemsa-staining, silver-staining, CMA fluorescence banding and fluorescencein situhybridisation (FISH) with rDNA probes. We analysed two subspecies, i.e. O. tenthredinifera subsp. neglecta (Parlatore, 1860) E.G. Camus, 1908 and O. tenthredinifera subsp. grandiflora (Tenore, 1819) Kreutz, 2004 by the traditional Feulgen method and constructed the karyotype. The cytotaxonomic implications for both taxa are also discussed. InHimantoglossum hircinum, FISH and silver staining highlighted differences in the number of two rDNA families (35S and 5S) with respect toBarlia robertiana(Loiseleur-Deslongchamps, 1807) Greuter, 1967. In addition, fluorescencein situhybridisation was also applied to diploid (2n= 2x= 36) and triploid (2n= 3x= 54)Anacamptis morio(Linnaeus, 1753) R.M. Bateman, Pridgeon et M.W. Chase, 1997. As far as we are aware, this is the first case of autotriploidy observed inA. morio.
Features of methods for monitoring the fuel cladding tightness in lead-cooled fast breeder reactors
Authors: Dragunova Anastasiya V. , Morkin Mikhail S. , Perevezentsev Vladimir V.
Published: December 2021

To timely detect failed fuel elements, a reactor plant should be equipped with a fuel cladding tightness monitoring system (FCTMS). In reactors using a heavy liquid-metal coolant (HLMC), the most efficient way to monitor the fuel cladding tightness is by detecting gaseous fission products (GFP).

The article describes the basic principles of constructing a FCTMS in liquid-metal-cooled reactors based on the detection of fission products and delayed neutrons. It is noted that in a reactor plant using a HLMC the fuel cladding tightness is the most efficiently monitored by detecting GFPs. The authors analyze various aspects of the behavior of fission products in a liquid-metal-cooled reactor, such as the movement of GFPs in dissolved and bubble form along the circuit, the sorption of volatile FPs in the lead coolant (LC) and on the surfaces of structural elements, degassing of the GFPs dissolved in the LC, and filtration of cover gas from aerosol particles of different nature.

In addition, a general description is given of the conditions for the transfer of GFPs in a LC environment of the reactor being developed. Finally, a mathematical model is presented that makes it possible to determine the calculated activity of reference radionuclides in each reactor unit at any time after the fuel element tightness failure. Based on this model, methods for monitoring the fuel cladding tightness by the gas activity in the gas volumes of the reactor plant will be proposed.
Delivering Patient-Centered Care in the Midst of a Cultural Conflict: The Role of Cultural Competence
Authors: Campinha-Bacote Josepha
Published: December 2021

At the core of both patient centeredness and cultural competence is the importance of seeing the patient as a unique person. For the purpose of this article, cultural competence is viewed as an expansion of patient-centered care. More specifically, cultural competence can be seen as a necessary set of skills for nurses to attain in order to render effective patient-centered care. However, a vexing question remains, “How does the nurse deliver patient-centered care when the patient’s health beliefs, practices, and values are in direct conflict with medical and nursing guidelines?” The purpose of this article is to provide nurses with a set of culturally competent skills that will enhance the delivery of patient-centered care in the midst of a cultural conflict. I will begin by offering a conceptual framework for cultural competence and a description of the cultural skill needed to formulate a mutually acceptable and culturally relevant treatment plan for each patient. Next I will describe effective approaches for cultural encounters. Finally I will present a vignette that illustrates how the nurse can deliver patient-centered care when the patient’s health beliefs, practices, and values are in direct conflict with medical and nursing guidelines

Anthropology and development in Germany
Authors: Bierschenk Thomas
Published: December 2021

The history of anthropology’s engagement with development in the post-World War II German-speaking world (Germany, Austria and Switzerland) can be divided into three phases: from being strongly rejected by most professorial chair holders (to around 1980), through the emergence of a subfield of anthropology (from 1980) and into the mainstream of the discipline (since around 2000). However, this perspective presupposes a broad definition of “anthropology of development” that encompasses more than the application of anthropological knowledge in development cooperation, as is often implied by the term “development anthropology”. In the slow modernisation process of German anthropology over the last fifty years – as defined by the discipline’s turn towards the modern world and its rapid internationalisation – the critical study of development as a field of professional practice has played a pioneering role by providing important theoretical and methodological stimuli. Together with their European colleagues, not least from APAD, German-speaking anthropologists have developed a particular style that has also been referred to as the “anthropology of development based on anthropology in development”. Today, the anthropology of development has evolved into an ethnographic inquiry of global social engineering.
Expressions et évolutions de l’anthropologie du développement au Vietnam
Authors: Culas Christian , Pannier Emmanuel , Truong Thi Thu Hang
Published: December 2021

L’objectif de cet article est de saisir les expressions et les évolutions de l’anthropologie du développement au Vietnam. En partant des prémices de l’anthropologie au xixe siècle, nous analysons les relations entre le pouvoir central et la discipline jusqu’à aujourd’hui. Quels que soient les époques et les régimes, l’anthropologie est au service de l’État et du développement, si bien que l’anthropologie du développement comme recherche appliquée domine largement la scène au détriment d’une anthropologie du développement académique plus critique et réflexive. Cet état des lieux nous amène à situer les différentes positions des anthropologues vietnamiens par rapport aux positions idéal-typiques identifiées dans la littérature spécialisée. Entre l’anthropologie appliquée, l’anthropologie académique et l’anthropologie impliquée, la discipline est façonnée par les contraintes idéologiques et financières imposées par l’État-parti d’un côté et par les ONG et agences de développement internationales de l’autre. Certains anthropologues parviennent néanmoins à exprimer, dans les interstices, des positions plus critiques sur les projets de développement et les idéologies qui les portent.
Représentations et images du corps dans l’émergence du sport moderne (xixe-xxe siècles)
Authors: Loudcher Jean-François
Published: December 2021

Deux « figures » majeures, l’Homme à la fin du xviiie siècle (Foucault, 1966) et le Surhomme un siècle plus tard, sont liées à l’avènement du sport moderne. Analyser comment elles se mettent en place suppose de prendre en compte leurs représentations corporelles à partir des conceptions de la santé (Canguilhem, 1972) et des images produites. Ainsi, la première, nourrie des conceptions anciennes (ontologique et dynamique), détermine des conceptions qualitatives et quantitatives renvoyant à des images de corps lourds et lents. Ces représentations ouvrent alors sur la conception normative de la moyenne (Canguilhem, 1972) et une éducation physique éclectique dans le contexte culturel et politique particulier de la IIIe République. Avec l’éthique de « l’exploit » et du dépassement, essentielle au sport moderne, des images du corps aux muscles plus sveltes et saillants se répandent, en même temps qu’apparaît une diversité des normes. Leur individualisation pose alors la question de l’existence même des corps et des individus, rendant difficile leur représentation, à l’instar de certaines conceptions de l’art sportif. Dépasser l’aspect normatif mène à privilégier le processus d’adaptation.
Sports à domicile

Published: December 2021

Dans le contexte du développement des sports, et de l’incitation à s’exercer individuellement et à domicile, la salle de culture physique investit la sphère domestique, devenant dans l’entre-deux-guerres l’un des centres d’intérêt d’ensembliers en prise avec l’évolution des mœurs. Si les types d’espaces investis dans la demeure sont variés, leur vocation avant tout fonctionnelle, leur dépouillement et leur contenu, essentiellement composé d’agrès, d’accessoires et de machines, interrogent la nature même de l’intervention du décorateur. Alors que le décor tend à disparaître au profit d’une approche fonctionnaliste, certaines propositions se démarquent en ce qu’elles relèvent d’une démarche plus architecturale, intégrant la zone de la pratique sportive à des espaces décloisonnés réunissant les activités essentielles du quotidien.
Idéologie de l’hypertrophie musculaire au cinéma
Authors: Maillet Arnaud
Published: December 2021

En matière de culture visuelle, l’opposition entre culture populaire et culture de masse engendre une image double des corps athlétiques aux muscles hypertrophiés dans le cinéma mainstream. Du point de vue de la culture populaire, la culture visuelle des athlètes bodybuildés symbolise la force de l’esprit qui lutte contre le mal, les inégalités et les injustices. Elle est aussi celle qui fait accéder les corps sportifs à une certaine forme de divinité, celle « des dieux du stade ». En revanche, élaborée dans le cadre d’une culture de masse, l’image des culturistes constitue alors non seulement une énième forme de contrôle social par une représentation qui marchandise les corps, mais encore un moyen coercitif de conversion des esprits à l’individualisme, notion-clef de l’idéologie néolibérale.

Après avoir suscité l’intérêt de grands historiens de l’art de la fin du xixe siècle, la question du multiple à la Renaissance était tombée en défaveur, à l’exception d’un certain nombre de techniques, comme l’estampe, les plaquettes ou la médaille. Depuis une quarantaine d’années, des expositions ou des monographies capitales sur la sculpture et des études sur la culture matérielle, sur la fabrication des bronzes ou sur la diffusion du portrait ont renouvelé notre vision de la production artistique au xve et au xvie siècle. Il semble plus approprié d’employer le terme de production plurielle pour un bon nombre d’artefacts, particulièrement dans le domaine du stuc, de la terre cuite et de la cartapesta. De grandes précautions doivent être prises en revanche dans celui des petits bronzes, au moins jusqu’aux ateliers padouans vers 1500, le désir de produire des objets uniques ou à très peu d’exemplaires ayant eu un poids déterminant.

The production of devotional reliefs, flourished in 15th century in Florence, where models from Renaissance Masters were reproduced in series by using a large variety of materials. One of the most frequently used is gypsum plaster, often referred to as “stucco” or “gesso”. Despite devotional reliefs wide diffusion, details concerning their constitutive materials and manufacture are insufficiently studied. In the framework of a research program fostered by the Louvre Museum, a multi-analytical approach was devised to investigate the composition and structure of micro samples obtained from a total of twenty-six representative artworks attributed to seven Florentine Masters. New evidence related to i) accessory minerals, ii) minor and trace elements, and iii) pores microstructure, disclosed important insights into the production of 15th century Florentine botteghe. These evidences, corroborated by the activity of some artists across Italy, raise new hypotheses on the attribution of some of these Madonne di gesso and their production outside Florence.

Gypsiferous rocks of Tuscany and derived materials (i.e. alabaster, stucco and gesso) have been frequently used as sculptural materials. Remarkable examples are attested from the Renaissance Florence. At the junction of two ongoing programs, dealing respectively with the study of 15th century stucco reliefs (called Madonne di gesso) and the provenance of European alabasters used in artworks, an investigation on raw gypsum supply was conducted via a geological survey in the surroundings of Florence. Looking for geochemical provenance markers, a multi-analytical approach was carried out on 30 geo-referenced rock samples. In particular, trace elements, related both to gypsum and synsedimentary minerals, and gypsum multi isotopic fingerprints (S, O, Sr) were tested. The results obtained are discussed, disclosing insights in the geo-sourcing of raw materials used for stucco reliefs in Florentine workshops.

This study proposes a proteomic-based strategy for the identification of proteins and their biological origin in stucco artworks from Italian Renaissance period in the context of the ESPRIT project (Études des Stucs Polychromés de la Renaissance Italienne). Three samples were studied: Virgin and Child, type Santa Maria Nuova (after Antonio Rossellino) from the Louvre Museum collection in Paris (Campana 19); Virgin and Child (after Benedetto da Maiano) (MBA 507) and Virgin and Child (Circle of Luca della Robbia) (MBA 247), both from the Museum of Fine Arts in Strasbourg collection. The analytical methodology was firstly evaluated using stucco mock up built with model proteins/binders. Various protocols were tested to extract very limited amounts of proteins from the inorganic matrix. The optimized workflow was successfully applied to historic samples showing identification of collagens and their biological origin.

Published: December 2021

With advances in communication technologies, virtual reality (VR) has become increasing popular. This study investigated the influence of virtual experiences on advertising effects. A 2 (virtual experience immersion: high vs. low) × 2 (virtual experience product control: high vs. low) × 2 (virtual experience product stimulation: high vs. low) between-subjects design was conducted. The results revealed that compared with the low-immersion virtual experience, the high-immersion virtual experience produced better advertisement attitudes. Furthermore, virtual experiences with high product control generated better advertisement attitudes when compared with virtual experiences with low product control. The two-way interactions between virtual experience product stimulation and immersion and between virtual experience product stimulation and virtual experience product control induced better brand attitude and purchase intention. In addition, telepresence and perceived enjoyment mediated the relationship between virtual experience and advertisement attitudes.

Personalized information retrieval is an effective tool to solve the problem of information overload. Along with the rapid development of emerging network technologies such as cloud computing, however, network servers are becoming more and more untrusted, resulting in a serious threat to user privacy of personalized information retrieval. In this paper, we propose a basic framework for the comprehensive protection of all kinds of user privacy in personalized information retrieval. Its basic idea is to construct and submit a group of well-designed dummy requests together with each user request to the server, to mix up the user requests and then cover up the user privacy behind the requests. Also, the framework includes a privacy model and its implementation algorithm. Finally, theoretical analysis and experimental evaluation demonstrate that the framework can comprehensively improve the security of all kinds of user privacy, without compromising the availability of personalized information retrieval.

This study proposes a method for mining potential user requirements from users’ nonverbal behaviors by analyzing their operational problems, since human behaviors reflect emotions and operational bottlenecks in human-machine interactions. Taking a single daily operation task as an example, three key steps were included in the method: first, modeling users’ operation and constructing the operation chain; second, finding emotional or physical problems in the operation chain, where the problems were defined mathematically as an emotional or physical load at each suboperation; and third, defining and obtaining potential user requirements by improving the operational problems when performing a task. Furthermore, a daily operation task was introduced to demonstrate and validate the method of mining user potential requirements. The results indicate that it is effective to discover the potential needs for a specific product and provide satisfactory solutions by calculating and optimizing operational problems.

Objetivo: analisar as representações sociais do graduando de enfermagem e identificar em seu discurso elementos que influenciam na promoção de conforto aos pacientes monitorizados. Método: Trata-se de estudo observacional, transversal, descritivo-exploratório, com abordagem qualitativa, cuja observação dos dados ocorreu à luz das representações sociais de Moscovici. A técnica escolhida foi a análise de conteúdo proposta por Bardin e, para facilitar a arrumação dos dados, foi utilizado o software IRAMUTEQ 0.7, alpha 2. Resultados: Foram entrevistados 57 graduandos de enfermagem de universidade privada do Rio de Janeiro que já cursaram as disciplinas de ensino clínico ou estágio curricular supervisionado em alta complexidade, conforme critérios de inclusão da pesquisa e, em sua maioria, componentes da geração Y. Este estudo revelou que o graduando de enfermagem considera o conforto do paciente monitorizado nos quatro contextos possíveis: físico, ambiental, psicoespiritual e social; e que a tecnologia dura em questão, o monitor multiparamétrico, representa importante parceria no cuidar do paciente crítico, porém, não em detrimento do conforto que, para o graduando, é perfeitamente possível em concomitância. Conclusão: Conclui-se que a formação biomédica e centrada em altas tecnologias no ambiente de terapia intensiva vem dando espaço à humanização e aos cuidados holísticos e confortantes, e que os novos profissionais, já habituados ao contato constante com tecnologias diversas, as respeitam, porém consideram prioritariamente o cuidado e o conforto da coletividade.
