Um estudo sobre a utilização do NFC: Tecnologia que tende a aproximar a Internet das Coisas da vida dos brasileiros

TCC (graduação) - Universidade Federal de Santa Catarina. Centro de Ensino. Tecnologias da Informação e Comunicação.Internet das coisas (IoT) e NFC (Nead Field Communication) são assuntos que estão em alta em diversos países. O objetivo deste trabalho é identificar a concepção de entrevistado sobre a tecnologia NFC e propor algumas aplicações para aumentar a sua utilização no Brasil. Para identificar a concepção destes indivíduos foi aplicado um questionário para traçar o perfil do entrevistado, seu conhecimento sobre as tecnologias citadas e seu grau de aceitação sobre elas. Como resultado obteve-se que 43,3% dos entrevistados conhecem IoT e o NFC, sendo que 29,2% atua na área de tecnologias. Outra informação relevante é que a maioria dos entrevistados visualizam a utilização do NFC em inúmeras soluções futuras. Quanto a proposta de aplicações, foram elaborados três experimentos para auxiliar no cotidiano desses usuários. O resultado dos experimentos foram satisfatórios.Internet of Things (IoT) and NFC (Nead Field Communication) are subjects that are on the rise in several countries. The objective of this work is to identify the conception of Brazilian individuals about NFC technology and to propose some applications to increase their use in Brazil. To identify the conception of these individuals, a questionnaire was applied to draw the profile of the interviewee, their knowledge about the technologies cited and their degree of acceptance of them. As a result it was obtained that 43.3 % of people know IoT and NFC, with 29.2 % working in the area of technologies. Other relevant information is that most respondents view the use in NFC many future solution. Regarding the applications proposal, three exercises were elaborated to assist in the daily life of these users. The results of the experiments were satisfactory

Global variation in diabetes diagnosis and prevalence based on fasting glucose and hemoglobin A1c

Fasting plasma glucose (FPG) and hemoglobin A1c (HbA1c) are both used to diagnose diabetes, but these measurements can identify different people as having diabetes. We used data from 117 population-based studies and quantified, in different world regions, the prevalence of diagnosed diabetes, and whether those who were previously undiagnosed and detected as having diabetes in survey screening, had elevated FPG, HbA1c or both. We developed prediction equations for estimating the probability that a person without previously diagnosed diabetes, and at a specific level of FPG, had elevated HbA1c, and vice versa. The age-standardized proportion of diabetes that was previously undiagnosed and detected in survey screening ranged from 30% in the high-income western region to 66% in south Asia. Among those with screen-detected diabetes with either test, the age-standardized proportion who had elevated levels of both FPG and HbA1c was 29-39% across regions; the remainder had discordant elevation of FPG or HbA1c. In most low- and middle-income regions, isolated elevated HbA1c was more common than isolated elevated FPG. In these regions, the use of FPG alone may delay diabetes diagnosis and underestimate diabetes prevalence. Our prediction equations help allocate finite resources for measuring HbA1c to reduce the global shortfall in diabetes diagnosis and surveillance

Global variations in diabetes mellitus based on fasting glucose and haemogloblin A1c

Fasting plasma glucose (FPG) and haemoglobin A1c (HbA1c) are both used to diagnose diabetes, but may identify different people as having diabetes. We used data from 117 population-based studies and quantified, in different world regions, the prevalence of diagnosed diabetes, and whether those who were previously undiagnosed and detected as having diabetes in survey screening had elevated FPG, HbA1c, or both. We developed prediction equations for estimating the probability that a person without previously diagnosed diabetes, and at a specific level of FPG, had elevated HbA1c, and vice versa. The age-standardised proportion of diabetes that was previously undiagnosed, and detected in survey screening, ranged from 30% in the high-income western region to 66% in south Asia. Among those with screen-detected diabetes with either test, the agestandardised proportion who had elevated levels of both FPG and HbA1c was 29-39% across regions; the remainder had discordant elevation of FPG or HbA1c. In most low- and middle-income regions, isolated elevated HbA1c more common than isolated elevated FPG. In these regions, the use of FPG alone may delay diabetes diagnosis and underestimate diabetes prevalence. Our prediction equations help allocate finite resources for measuring HbA1c to reduce the global gap in diabetes diagnosis and surveillance.peer-reviewe

Análise quantitativa da concordância entre usuários avaliadores de objetos de aprendizagem: um estudo de caso com dados do repositório Merlot

Dissertação (mestrado) - Universidade Federal de Santa Catarina, Campus Araranguá, Programa de Pós-Graduação em Tecnologias da Informação e Comunicação, Araranguá, 2020.Com o aumento contínuo do uso de objetos de aprendizagem é importante que os repositórios de objetos de aprendizagem (ROA) adotem estratégias para a garantia da qualidade dos recursos. Exemplos dessas estratégias são o sistema de avaliação por pares de especialistas, avaliação realizada pelos usuários com pontuação e/ou comentários, premiação do editor, entre outros. Por exemplo, o Merlot busca garantir a qualidade dos recursos por meio de avaliações e pontuações fornecidas por pares-revisores (especialistas) e pela comunidade de usuários de diferentes áreas. Como podem ocorrer discrepâncias na avaliação da qualidade dos objetos de aprendizagem, é necessário entender o grau de concordância entre os usuários que são avaliadores no Merlot. Diante disso, o presente trabalho tem como objetivo analisar a concordância e a existência de associações entre os usuários que realizaram avaliações dentro do repositório Merlot. Para isso, foram realizados dois estudos de caso com dados coletados no Merlot. O primeiro estudo de caso avaliou a concordância entre pares de avaliadores que classificaram o mesmo conjunto de recursos considerando suas disciplinas preferidas e área de especialização. O segundo estudo de caso mediu a associação entre as classificações das médias das notas fornecidas pelos avaliadores provenientes de diferentes categorias de disciplina. Os resultados apontaram que os usuários avaliadores apresentam grande divergência nas avaliações fornecidas para o mesmo recurso. Além disso, as classificações das médias dos recursos considerando os avaliadores de diferentes categorias de disciplina não mostraram correlação. Os resultados aqui encontrados podem ser utilizados para aprimorar os mecanismos de garantia da qualidade dentro dos repositórios, bem como para o desenvolvimento de novas formas de apresentação das informações relacionadas à qualidade dos recursos.Abstract: With the continuous increase in learning objects usage it is important that learning object repositories (LOR) adopt measures to assure the quality of their resources. Examples of these strategies are the peer review system, the assessment carried out by users with scores or/and comments, editor awards, among others. For instance, Merlot seeks to ensure the quality of the resources by using evaluations and scores provided by peer-reviewers (experts) and the community of users from different areas. As discrepancies in the assessment of the quality of learning objects may occur, it is necessary to understand the degree of agreement between users that are evaluators in Merlot. Considering this, the present work aims to analyze the agreement and the existence of associations between the users who performed evaluations inside the Merlot repository. For that, two case studies were carried out with data collected from Merlot. The first case study assessed the agreement between pairs of evaluators who rated the same set of resources and considering their preferred disciplines and area of expertise. The second case study measured the association between the average ratings of the resources given by evaluators coming from different categories of discipline. Results pointed out that evaluators present a great disagreement in the ratings they give for the same resource. Moreover, the average ratings of the resources considering the evaluators from differnt categories of discipline have shown no correlation. The results found here may be used to improve the mechanisms for quality assurance inside the repositories as well as the development of new forms of presenting the information related to the quality of the resources
