Integrated turbulence parameters estimation from NAOMI AO telemetry data

Monitoring turbulence parameters is crucial in high-angular resolution astronomy for various purposes, such as optimising adaptive optics systems or fringe trackers. The former are present at most modern observatories and will remain significant in the future. This makes them a valuable complementary tool for the estimation of turbulence parameters. The feasibility of estimating turbulence parameters from low-resolution sensors remains untested. We perform seeing estimates for both simulated and on-sky telemetry data sourced from the new adaptive optics module installed on the four Auxiliary Telescopes of the Very Large Telescope Interferometer. The seeing estimates are obtained from a modified and optimised algorithm that employs a chi-squared modal fitting approach to the theoretical von K\'arm\'an model variances. The algorithm is built to retrieve turbulence parameters while simultaneously estimating and accounting for the remaining and measurement error. A Monte Carlo method is proposed for the estimation of the statistical uncertainty of the algorithm. The algorithm is shown to be able to achieve per cent accuracy in the estimation of the seeing with a temporal horizon of 20s on simulated data. A 0.76" +/- 1.2%$|_\mathrm{stat}$ +/- 1.2%$|_\mathrm{sys}$ median seeing was estimated from on-sky data collected from 2018 and 2020. The spatial distribution of the Auxiliary Telescopes across the Paranal Observatory was found to not play a role in the value of the seeing

Un estudio de enfoque cuantitativo, de correlación y descriptiva, elaborado con objetivo de analizar el tiempo empleado por equipo de enfermería para asistir pacientes hospitalizados en Unidad de Cuidados Intensivos de Adultos y verificar su correlación con indicadores de calidad de la atención. La identificación del promedio de tiempo de cuidados y de indicadores de calidad asistencial fue realizada por medio de consulta a las herramientas de gestión utilizadas por el jefe de enfermería de la Unidad. El promedio de tiempo de cuidado ministrado a los pacientes se mantuvo equilibrado, pero inferior a los indicados por organismos oficiales en Brasil. La correlación entre tiempo de cuidados de enfermería e indicador de incidencia extubación accidental indicó que esta disminuye con aumento de tiempo de atención de enfermería utilizado por enfermeras. Los resultados de esta investigación demuestran la influencia del tiempo de atención de enfermería por las enfermeras, en los resultados de la atención prestada.Trata-se de studo de abordagem quantitativa, correlacional e descritivo, elaborado com o objetivo de analisar o tempo utilizado pela equipe de Enfermagem para assistir aos pacientes internados em unidade de terapia intensiva adulto, bem como verificar sua correlação com os indicadores de qualidade assistencial. A identificação do tempo médio de assistência despendido e dos indicadores de qualidade assistencial foi efetivada por meio de consulta aos instrumentos de gestão, utilizados pela chefia de Enfermagem da unidade. O tempo médio de assistência despendido com os pacientes manteve-se equilibrado, porém, inferior aos indicados pelos órgãos oficiais brasileiros. A correlacão entre o tempo de assistência de Enfermagem despendido por enfermeiros e o indicador incidência de extubação acidental indicou que a incidência de extubação acidental diminui, à medida que aumenta o tempo de assistência de Enfermagem despendido por enfermeiros. Os resultados desta investigação demonstram a influência do tempo de assistência de Enfermagem, provido por enfermeiros, no resultado do cuidado ministrado.The objective of this quantitative, correlational and descriptive study was to analyze the time the nursing staff spends to assist patients in Adult Intensive Care Units, as well as to verify its correlation with quality care indicators. The average length of time spent on care and the quality care indicators were identified by consulting management instruments the nursing head of the Unit employs. The average hours of nursing care delivered to patients remained stable, but lower than official Brazilian agencies' indications. The correlation between time of nursing care and the incidence of accidental extubation indicator indicated that it decreases with increasing nursing care delivered by nurses. The results of this investigation showed the influence of nursing care time, provided by nurses, in the outcome of care delivery

Carga de trabalho de enfermagem e ocorrência de eventos adversos na terapiaintensiva: revisão sistemática

OBJETIVO Identificar evidências sobre a influência da carga de trabalho de enfermagem na ocorrência de eventos adversos (EA) em pacientes adultos internados em Unidade de Terapia Intensiva (UTI). MÉTODO Revisão sistemática da literatura realizada nas bases de dados MEDLINE, CINAHL, LILACS, SciELO, BDENF e Cochrane deestudosem inglês, português ou espanhol, publicados até 2015. Os EA analisados foram infecção, úlcera por pressão (UPP), quedas e erros associados a medicamentos. RESULTADOS Das 594 pesquisas potenciais identificadas, oito compuseram a amostra final da revisão. O NursingActivities Score -NAS (37,5%) e o TherapeuticInterventionScoring System -TISS (37,5%) foram os instrumentos mais utilizados para avaliação da carga de trabalho de enfermagem. Seis pesquisas (75,0%) identificaram influência da sobrecarga de trabalho na ocorrência de infecção, UPP e uso de medicamentos. Uma investigação identificou que o NAS foi fator de proteção para UPP. CONCLUSÃO A carga de trabalho de enfermagem requerida por pacientes na UTI influenciou a ocorrência de EA, e os enfermeiros devem monitorar diariamente esta variável para garantir o correto dimensionamento da equipe e a segurança da assistência prestada.OBJECTIVE To identifyevidences of the influence of nursing workload on the occurrence of adverse events (AE) in adult patients admitted to the intensive care unit (ICU). METHOD A systematic literature review was conducted in the databases MEDLINE, CINAHL, LILACS, SciELO, BDENF, and Cochrane from studies in English, Portuguese, or Spanish, published by 2015. The analyzed AE were infection, pressure ulcer (PU), patient falls, and medication errors. RESULTS Of 594 potential studies, eight comprised the final sample of the review. TheNursing Activities Score (NAS; 37.5%) and the Therapeutic Intervention Scoring System(TISS; 37.5%) were the instruments most frequently used for assessing nursing workload. Six studies (75.0%) identified the influence of work overload in events of infection, PU, and medicationerrors. An investigation found that the NAS was a protective factor for PU.

Trust Levels Definition on Virtual Learning Platforms Through Semantic Languages

Trust level concept is a topic that has opened a knowledge area about the profile evaluation and the people participation in Social Networks. These have presented a high knowledge profit, but at the same time it is necessary to analyze a group of variables to determine the trust participants' degree. In addition, this is a topic that from some years ago has been presenting a big expectation to settle some alternatives to generate confidence in an activer community on internet. To establish these parameters it is important to define a model to abstract some variables that are involved in this process. For this, it is relevant to take into account the semantic languages as one of the alternatives that allow these kinds of activities. The purpose of this article is to analyze the Trust Levels definition in the contents that are shared on Open Source Virtual learning Platforms through the use of a model of representation of semantic languages. The last ones allow determining the trust in the use of learning objects that are shared in this kind of platforms

Temperature and precipitation reconstruction in southern Portugal during the late Maunder Minimum (AD 1675–1715)

This paper discusses the research carried out to check the climatic characteristics of the late Maunder Minimum (LMM) (AD 1675–1715) in the southwestern part of the Iberian Peninsula and as an aid towards pressure patterns reconstruction in the NE Atlantic and Europe. Documentary evidence reveals that interannual precipitation variability was similar to the present one, although some very severe dry periods occurred (particularly one in 1694). On the other hand, during the LMM there was a higher percentage of cold winter months, some of them with snowfall. A brief comparison is made with other areas from the Mediterranean. The relationships between weather similarities and differences for particular months is analysed in the light of the reconstructed synoptical patterns, and further research into historical climatic change of southern Europe is suggested.info:eu-repo/semantics/publishedVersio
