RESUMO No contexto atual, de subida dos custos de produção, é essencial otimizar a gestão dos recursos disponíveis, o que pressupõe a incorporação de tecnologias que melhorem o conhecimento sobre as variáveis envolvidas no processo produtivo. Este estudo teve por objetivo demonstrar os benefícios de definir e validar zonas de gestão (ZG) numa vinha. Para o efeito foram realizados dois levantamentos expeditos da parcela experimental, um realizado com um sensor de contacto (“Veris 2000 XA”) para medir a resistividade do solo e, a partir desta, a condutividade elétrica aparente do solo (CEa), e outro realizado com um recetor GNSS (Global Navigation Satellite System) de precisão (RTK) que permitiu o levantamento altimétrico. Os resultados foram submetidos a tratamentos geoestatísticos que permitiram a definição de três ZG com diferente potencial produtivo (menor, intermédio e maior). A validação das ZG foi realizada a partir de parâmetros do solo (textura, pH, matéria orgânica, humidade, fósforo, potássio, bases de troca e capacidade de troca catiónica) e de medições da compactação (índice de cone, IC), realizadas com um cone penetrómetro eletrónico. A análise estatística dos resultados confirmou que estes parâmetros validaram as ZG identificadas a partir dos dados da CEa e da altimetria. Esta validação comprova o interesse de ferramentas tecnológicas expeditas para monitorizar a CEa como uma etapa fundamental para implementar processos agronómicos inteligentes de tomada de decisão.

ABSTRACT In the current context of rising production costs, optimizing the management of available resources is crucial, specially by incorporating technologies that enhance our understanding of the variables involved in the agronomic production process. This study aimed to demonstrate the benefits of defining and validating management zones (MZ) in a vineyard. For this purpose, two quick surveys of the experimental field were conducted using a contact sensor (“Veris 2000 XA”), to measure the soil resistivity and thereby determine the soil apparent electrical conductivity (ECa), and another survey using a precision GNSS (Global Navigation Satellite System) receiver (RTK- Real Time Kinematics) for altimetric measurements. The results underwent geostatistical analysis to define three MZs with different productive potential (less, intermediate, and more productive potential). The validation of these MZs was based on various soil parameters (texture, pH, organic matter-OM, moisture content, phosphorous, potassium, exchange bases, and cation exchange capacity-CEC) and soil compaction measurements (cone index-CI) using an electronic cone penetrometer. Statistical analysis confirmed that these parameters validated the MZs identified from the ECa and altimetric data. This validation attests the value of using expeditious technological tools to monitor ECa as a key step to in implementing intelligent agronomic decision-making processes.

RESUMO O uso de sensores de solo tem sido uma alternativa para a redução dos custos com amostragem e análise de solo em laboratório, permitindo a adoção de uma maior densidade amostral. O presente estudo teve como objetivo desenvolver uma plataforma multisensor portátil para solo, com sensores de condutividade elétrica aparente, umidade, temperatura e resistência do solo à penetração. A plataforma multisensor foi desenvolvida com base no computador de placa única BeagleBone Black (BBB). Para os sensores de condutividade elétrica aparente e sensor de umidade, circuitos eletrônicos foram desenvolvidos. Uma célula de carga foi utilizada no sensor de resistência do solo à penetração. Para validação, dados de ECa, umidade e resistência à penetração obtidos utilizando a plataforma multisensor e sensores comerciais foram comparados entre si. Um módulo GNSS (Global Navigation Satellite System) de baixo custo foi utilizado para georreferenciamento dos pontos de coleta de dados. O custo com aquisição dos componentes necessários para montagem da plataforma multisensor foi de US$ 361,94. Para ECa, umidade e resistência à penetração média e máxima a correlação entre os dados obtidos com a plataforma multisensor e com os sensores comerciais foram 0,95; 0,92; 0,90 e 0,91, respectivamente. A forte correlação comprova que a plataforma multisensor desenvolvida tem precisão aceitável.

ABSTRACT Soil sensors are alternatively used to reduce the costs of soil sampling and be able to perform analyses in a laboratory. However, using individual sensors can result in low accuracy because the measured variable may be related to more than one soil characteristics. This study aimed to develop a portable soil multisensor platform with sensors for apparent electrical conductivity, moisture, temperature, and penetration resistance of the soil. The multisensor platform was developed based on a BeagleBone Black (BBB) single-board computer. Electronic circuits have been developed for electrical conductivity and moisture sensors. A load cell was used in the soil-penetration resistance sensor. For validation, the ECa, soil moisture, and penetration resistance data obtained using the multisensor platform and commercial sensors were compared. A low-cost global navigation satellite system module was used to georeference sampling points. The cost of acquiring the components required to assemble the multisensor platform was US$ 361.94. The strong correlation between the data obtained with the multisensor platform and commercial sensors proves that the developed multisensor platform has acceptable accuracy. The spatial variability of the apparent soil electrical conductivity, moisture, temperature, and penetration resistance in a coffee plantation can be characterized by the generated maps from the data obtained by the four sensors. laboratory However characteristics temperature BBB (BBB singleboard single board computer soilpenetration sensor validation ECa compared lowcost points US 36194 361 94 361.94 3619 36 9 361.9 3 361.

Resumen: Objetivo: Evaluar los factores relacionados con el uso del Expediente Clínico Electrónico (ECE) desde la percepción de los usuarios médicos y enfermeras de los servicios de salud de un hospital de 2do nivel en Morelos, México. Material y métodos: Se realizó el análisis cualitativo de 22 entrevistas semiestructuradas a personal médico, enfermeras, directivo y administrativo de un hospital de 2do nivel en Morelos, México, tomando como referencia de análisis las dimensiones de normatividad, operatividad y capacitación en la implementación del ECE. Resultados: Se identificó un número insuficiente de computadoras y personal capacitado para operar el ECE. Cuando se logra operar el expediente éste es lento o presenta fallas sistemáticas frecuentes debido a las redes de navegación dependen del navegador central que brinda soporte estatal a la plataforma del ECE sin una resolución pronta cuando hay fallas, las unidades hospitalarias trabajan 24 horas y a nivel central las operaciones del ECE tienen horarios de lunes a viernes de 8 horas. Esto incrementa la resistencia a adoptar el expediente como herramienta de trabajo. La organización colabora a la resistencia al no proporcionar un soporte técnico suficiente y permanente para afrontar las fallas de operatividad del ECE. Los usuarios consideran que el expediente es seguro y confiable, lo cual incrementaría la posibilidad de uso del ECE. Conclusiones: La falta de recursos e ineficiencias en la operación del ECE colaboran a una baja y lenta adopción del expediente; así como la resistencia a utilizarlo. La organización colabora a aumentar la resistencia si la capacitación no es eficiente. Falta le da soporte continuo y suficiente en la infraestructura técnica y recurso humano. A pesar la limitada e ineficiente adopción del ECE se identificaron áreas y personal donde se presenta una mayor utilización (hospitalización y personal médico). Éstas podrían ser las experiencias de aprendizaje positivo que pueden utilizarse para instruir a toda la organización

Abstract: Objective: To evaluate the factors related to the use of the Electronic Medical Record (ECE) from the perception of medical users of health services Morelos, Mexico. Material and methods: The qualitative analysis of 22 semi-structured interviews with medical personnel, nurses, managers and administrators of a 2nd level hospital in Morelos, Mexico was carried out, taking as a reference for analysis the dimensions of regulations, operability and training in the implementation of the ECE. Results: An insufficient number of computers and trained personnel were identified to operate the ECE. When it is possible to operate the file, it is slow or presents frequent systematic failures due to the navigation networks, they depend on the central browser that provides state support to the ECE platform without a prompt resolution when there are failures, the hospital units work 24 hours and centrally. ECE operations have 8-hour hours from Monday to Friday. This increases resistance to adopting the file as a working tool. The organization contributes to the resistance by not providing sufficient and permanent technical support to face the operational failures of the ECE. Users consider that the file is safe and reliable, which would increase the possibility of using the ECE. Conclusions: The lack of resources and inefficiencies in the operation of the ECE contribute to a low and slow adoption of the file; as well as the resistance to use it. The organization helps increase resistance if training is not efficient. Lack gives you continuous and sufficient support in the technical infrastructure and human resources. Despite the limited and inefficient adoption of ECE, areas and personnel were identified where there is greater use (hospitalization and medical personnel). These could be positive learning experiences that can be used to educate the entire organization

The COVID-19 pandemic has warranted modifications to clinical research implementation to ensure adherence to public health and safety measures. Often, this modification has necessitated a deviation from the traditional face-to-face approach to an electronic or hybrid consent process. We assessed the acceptability and preference for electronic consent and explored understanding of the electronic consent information - an outcome which is vital in providing reassurance that consent is provided with full appreciation of the risks and benefits of study participation. In this descriptive study, healthcare professionals (HCPs) were invited, through a database of HCP contacts, snowball sampling and advertisement, to participate in an online survey between 14 July 2021 and 17 September 2021, to explore their experiences of providing electronic consent for enrolment into the largest implementation trial of a COVID vaccine in South Africa (SISONKE Trial). Descriptive analysis was used to characterise respondents and categorical data were expressed as frequencies. The prevalence of recurring responses to open-ended questions allowed for the identification of themes. A total of 1025 HCPs completed the online survey. Access to a COVID-19 vaccine was the strongest motivating factor for enrolment (82.3%) into the SISONKE Trial. Over a third of participants (38.6%) were not able to discuss the study with research staff. While the majority of participants (85.2%) indicated that online consent was acceptable, it was recognised that acceptability was context specific. Although 64% indicated awareness that reporting both a positive COVID test and adverse events were requirements, a significant percentage (32%) did not recall that the reporting period was 2 years. The electronic consent process was easily navigated by educated HCPs with access to electronic devices and data. Vaccine access was the most important motivation for participation, thus raising questions about how voluntary the consent process was and the role of desperation in deciding to participate. SIGNIFICANCE: • Navigation of the electronic consent process for participation in a COVID-19 vaccine implementation trial is not a challenge for educated healthcare professionals with access to electronic devices and data. However, technical skills and access to technology may impact the integrity of the informed consent process for lay research participants. • Motivation to join research studies for access to scarce resources impacts negatively on the authenticity of the consent processes, as participation may be informed but not truly voluntary, and is an issue that ethics committees and researchers should address.

RESUMO A ocorrência de desorientação espacial foi observada no comprometimento cognitivo leve (CCL) e está associada a um maior risco de progressão para a doença de Alzheimer (DA). No entanto, não há um padrão ouro para avaliação da orientação espacial e os testes em papel e caneta não apresentam validade ecológica. Recentemente, um número cada vez maior de estudos têm apontado o papel da desorientação espacial como um marcador cognitivo do declínio patológico, lançando uma nova luz sobre sua importância para o CCL. Esta revisão sistemática teve como objetivo investigar a acurácia de tarefas de orientação espacial para se estabelecer o diagnóstico de CCL entre idosos cognitivamente saudáveis. A pesquisa foi realizada através das bases de dados Medline/PubMed, Web of Science, Scopus, Embase, Lilacs e Scielo. Apenas artigos originais que reportassem avaliação da orientação espacial em idosos CCL comparados a um grupo controle saudável foram incluídos. Foram excluídos os estudos que não utilizassem a classificação de CCL segundo critérios bem descritos e/ou que não reportassem resultados de acurácia da avaliação da orientação espacial. Sete estudos atenderam aos critérios de elegibilidade, descrevendo uma variedade de formas de avaliação da orientação espacial, incluindo questionários, tarefas em papel e lápis, tarefas de aprendizado de rotas no escritório, tarefas baseadas em computador e com realidade virtual. As tarefas de orientação espacial demonstraram acurácia moderada a alta na detecção de CCL em comparação com idosos cognitivamente saudáveis, com áreas sob a curva (area under the curve — AUC) variando de 0,77 a 0,99. No entanto, um viés metodológico importante foi identificado nos estudos selecionados, o que deve ser levado em consideração na interpretação dos resultados. Apesar da inclusão da orientação espacial na avaliação cognitiva em CCL parecer ter um valor significativo, mais estudos são necessários para esclarecer sua verdadeira capacidade de distinguir o envelhecimento patológico do não patológico.

Abstract Spatial disorientation has been observed in mild cognitive impairment (MCI) and is associated with a higher risk of progression to Alzheimer's disease (AD). However, there is no gold standard assessment for spatial orientation and paper-and-pencil tests lack ecological validity. Recently, there has been an increasing number of studies demonstrating the role of spatial disorientation as a cognitive marker of pathological decline, shedding new light on its importance for MCI. This systematic review aimed to investigate the accuracy of spatial orientation tasks for the diagnosis of MCI by comparison with cognitively healthy elderly. The search was conducted in the databases Medical Literature Analysis and Retrieval System Online (MEDLINE/PubMed), Web of Science, Scopus, Excerpta Medica Database (Embase), Literatura Latino-Americana e do Caribe em Ciências da Saúde (Lilacs) and Scientific Electronic Library Online (SciELO). Only original studies reporting spatial orientation assessment in MCI patients compared to a healthy control group were included. Studies were excluded if the MCI classification did not follow well described criteria and/or if accuracy results of spatial orientation assessment were not provided. Seven studies met the eligibility criteria, describing a variety of spatial orientation assessments including questionnaires, paper-and-pencil, office-based route learning, and computer-based and virtual reality tasks. Spatial orientation tasks demonstrated moderate to high accuracy in detecting elderly with MCI compared to cognitively healthy elderly, with areas under the curve (AUC) ranging from 0.77 to 0.99. However, important methodological issues were found in the selected studies which should be considered when interpreting results. Although the inclusion of spatial orientation assessments in MCI evaluations seems to have significant value, further studies are needed to clarify their true capacity to distinguish pathological from non-pathological aging.

RESUMEN Se implementó un campo patrón de verificación de equipos topográficos. Este fue geo-referenciado con un instrumento de estación total y mediante procedimientos de repetibilidad y reproducibilidad. Se realizaron posicionamientos estáticos GNSS (por las siglas en inglés de Global Navigation Satellite System) con equipo doble-frecuencia, sensibilizando el tiempo de ocupación, la hora del día, las coordenadas sin corregir y sometidas al procedimiento de corrección diferencial y el tipo de coordenadas obtenidos. Lo anterior permitió una evaluación de la precisión y exactitud del posicionamiento GNSS con el método estático, encontrándose un error medio cuadrático global de 1 cm para condiciones sin efecto de multi-trayectoria y de 4 cm para los puntos del campo de verificación cercanos a edificios. Adicionalmente se encontraron resultados óptimos para tiempos de ocupación de 30 minutos y la necesidad de utilizar coordenadas planas cartesianas para garantizar la compatibilidad con los levantamientos utilizando la medición electrónica de distancias, lo cual permite utilizar el posicionamiento GNSS estático para georreferenciar redes topográficas de precisión y pueden ser usadas para diferentes aplicaciones en ingeniería civil.

ABSTRACT A field check was implemented for calibrating surveying equipment. It was geo-referenced with a Total Station Theodolite and by implementing procedures concerning repeatability and reproducibility. We carried out GNSS (Global Navigation Satellite System) static positioning with double frequency equipment, sensitizing occupation times, day times, uncorrected coordinates subjected to a differential correction procedure and type of coordinates obtained. This facilitated an evaluation of precision and accuracy for the GNSS positioning with the static method, which gave a global RMSE (root mean square error) of 1 cm for conditions with no multi-path effect and 4 cm for field calibration points close to buildings. Additionally, optimal results for occupation times of 30 minutes were found, and the need to use planar Cartesian coordinates to ensure compatibility with the surveys using electronic measurement of distances, which allows the use of the static GNSS positioning for geo-referencing precise surveying networks, and can be used in different applications in Civil Engineering.

This contribution focuses on the transport of passengers on international routes and the legal regime set down by the Warsaw Convention of 1929 and reinforced by the Montréal Convention of 1999. These Conventions regulate commercial aviation by detailing a set of minimum standardised procedures for flight safety, such as standards for air navigation systems, amongst others, to ensure safe and efficient air travel. The legal regime also regulates the possible claims that may be made against airlines for the death of or harm to passengers, as well as relating to damage to and loss of baggage. The regime not only limits claims temporally and by location, but it also excludes the application of national legal regimes. With regard to claims of harm to dignity the regime disallows such claims to be brought within the restrictions placed by the legal regimes or on any other basis. The contribution does not address the full coverage of these Conventions, only the exclusion of mental / emotional injuries. The Convention excludes emotional harm from the definition of death and physical harm. However claimants have brought claims to undermine the main exclusion of claims with regard to compensation for emotional harm. This contribution explores the exclusion of claims in the Warsaw and Montréal Conventions and thereafter analyses two court decisions in common law countries where this exclusion of claims was challenged and the challenge failed.

ABSTRACT The GPS is a satellite navigation system that provides location and time information. Such a system currently supports critical applications for military, civil and commercial users worldwide and is accessible to any operator by using a single GPS receiver. However, although being too dependent on GPS signals, just a few of these applications present some kind of countermeasure to electromagnetic attacks, showing a high level of vulnerability to intentional attacks. In this paper, we pose questions and situations related to security and vulnerability of different kinds of platforms/vectors and systems which directly afflict the situational awareness of operators. Experiments were made with different general GPS receivers as a function of distance and incidence angle, showing that they fail to work even at low jamming powers (−25 and 0 dBm at 10 m). More complex GPS systems, such as aeronautical receivers, were also tested, losing completely the tracking at −30 dBm, when a 0° (levelled) and 10 m far electromagnetic jamming signal is incident on its antenna. A specific open source, free software (JammPy) allows extending these experimental results, providing a roadmap and estimating how much jamming power is necessary to cause damage to these systems.

Introduction: The aim of this paper is to perform an updated review of the literature on surgical planning and navigation in the management of head and neck oncological pathology, and to assess and determine its current applications. Material and methods: An electronic search was conducted using the terms: "craniomaxillofacial tumors", "head and neck cancer", "navigation system", "computer-assisted surgery", and "oral cancer". Results: Sixteen articles have been published between 1991 and 2014. These are 5 reviews, 6 case series, and 5 case reports, but no systematic review. There were 10 articles that provided complete information regarding oncological disease managed with surgical navigation technology. Navigation applications in head and neck oncology can currently be divided into the following categories: guided biopsy, tumor resection and reconstruction, monitoring tumor volume, control of surgical resection margins based on CT, MRI or PET, and interdisciplinary communication network. Conclusions: Currently, there are a limited number of publications on the applications of surgical navigation in the new field of head and neck oncology. Despite the lack of systematic reviews, there seems to be a promising future for the valuable contribution made by navigation to the management of head and neck tumors, by providing anatomic and diagnostic accuracy, and surgical safety. Navigation will show to be of great use in the multidisciplinary cancer treatment.

Introducción: El objetivo de este trabajo es hacer una revisión y actualización de la literatura sobre la aportación de la planificación quirúrgica y de la navegación en el manejo de la enfermedad oncológica de cabeza y cuello, para valorar y determinar sus aplicaciones actuales. Material y métodos: Se realiza una búsqueda electrónica empleando los términos craniomaxillofacial tumors, head and neck cancer, navigation system, computer-assisted surgery y oral cancer. Resultados: El número de artículos encontrados en la revisión de la literatura ha sido de 16, publicados entre los años 1991 y 2014. Entre ellos no hay ninguna revisión sistemática, hay 5 artículos de revisión, 6 series de casos y 5 casos clínicos. Solo 10 artículos aportan información completa en relación con la enfermedad oncológica manejada con tecnología de navegación quirúrgica. Actualmente las aplicaciones de la navegación en oncología de cabeza y cuello pueden enumerarse en las siguientes áreas: biopsia guiada, resección y reconstrucción de tumores, monitorización del volumen del tumor, control de márgenes de resección quirúrgica basados en TC, RMN o PET y sistema de comunicación interdisciplinar. Conclusiones: Actualmente hay un número escaso de publicaciones sobre las aplicaciones de la navegación quirúrgica en el novedoso ámbito de la oncología de cabeza y cuello. A pesar de la ausencia de revisiones sistemáticas, parece tener un futuro prometedor por la valiosa aportación que hace para el manejo de tumores de cabeza y cuello, como proporcionar precisión anatómica, precisión diagnóstica y seguridad quirúrgica, siendo de gran utilidad en el tratamiento oncológico multidisciplinar.

ABSTRACT This article deals with the problem of Earth’s magnetic field sensors calibration in the context of low-cost nanosatellites’ navigation systems. The attitude of space vehicles can be determined from the state estimation using information from three-axis inertial and non-inertial sensors. This study considers a three-axis solid-state magnetometer. In the vehicle itself, the presence of ferrous materials and electronic devices creates disturbances, distorting the measured field. The sensor precision can be enhanced through calibration methods which calculate the systematic error. The objective here is to study and implement calibration combining a geometric method and the TWOSTEP algorithm. The methodology is based on numerical simulations, with the development of a database of the Earth’s magnetic field along the vehicle orbit, and experimental tests using a nanosatellite mockup, containing an embedded processor Arduino MEGA 2560 platform and the magnetometer HMC5843.

Resumo Este artigo aborda o processo de transformações políticas e econômicas ocorrido na Província do Grão-Pará, no período de 1840 a 1871. No texto, discutimos a questão da Escola Normal e, por conseguinte, da instrução pública na formação de professores, em meio a essas transformações, que foi escolhida pela classe política e abastada da Província do Grão-Pará como um mecanismo de propagação dos ideais modernos de ordenamento, progresso e civilização entre os cidadãos que circulavam pelo centro da capital da referida província, a cidade de Belém. Nesse sentido, também optamos por situar estas mudanças em relação às medidas políticas do governo imperial, como a abertura à navegação internacional do Rio Amazonas, a criação da Província do Amazonas e a introdução da navegação a vapor como forma de integração ao restante do país e de desenvolvimento regional. Na metodologia, adotamos estudo documental, com consulta aos relatórios e outras fontes históricas do período, constantes de microfilme em sítio eletrônico (http://www.crl.edu/area-studies/ lamp), bem como o uso de referências bibliográficas de autores que discorrem acerca do referido período.

Abstract This article discusses the process of political and economic transformations that occurred in the Province of Grão-Pará, in the period 1840-1871. In the text, we discuss the issue of the Normal School and therefore public education in teacher training, in the midst of these changes, which was chosen by the political and wealthy class of the Province of Grão - Pará as a propagation mechanism of modern planning, progress and civilization ideals among citizens who circulated through the center of the capital of that province, the town of Bethlehem. In this sense, we also opted to situate these changes in relation to the political measures of the imperial government, as openness of the Amazon River to international navigation, the creation of the province of Amazonas and the introduction of steam navigation as a way of integration with the rest of the country and regional development. In the methodology, we adopt documentary study, consulting reports and other historical sources of the period within the microfilms of the electronic site (http://www.crl.edu/area-studies/lamp), as well as the use of references to authors who talk about that period.

Recognizing insect species by specialists is considerably improved when electronic guides are used, besides those represent an excellent teaching material. In an order like Thysanoptera, this tool becomes particularly needed. To make known the first electronic guide for identification of Trips presented in the Guantanamo province is the main goal of this note. A structured information combining organized documents, images and videos, including new species reports for Cuba and Science, is shown. A friendly interface with three main navigation menus, which prioritizes the easy understanding by users through descriptions and pictures of the main characteristics, was generated. A combination of species identification in each municipality, their function in the agroecosystem and their distribution according to the climatic factors in the region was achieved.

El reconocimiento de las especies de insectos por parte de especialistas, se facilita mucho cuando poseen una guía electrónica. En un orden donde las especies son de difícil identificación como Thysanoptera esta herramienta es necesaria. El objetivo de esta nota es dar a conocer la existencia de una guía electrónica para el trabajo de identificación de los Trips presentes en la provincia de Guantánamo. La guía muestra una información estructurada que combina documentación, imágenes y videos de forma organizada, incluyendo nuevos informes de especies para Cuba y para la ciencia. Se generó una interfaz amigable con tres menús principales de navegación, que priorizan el fácil entendimiento de los usuarios a través de las descripciones y imágenes de las principales características. Se logró una combinación de la identificación de las especies presentes por municipio, su función en el agroecosistema y su distribución de acuerdo a los factores climáticos de la región.
