Cataract surgery and functional vision : the challenge of a more objective approach in pre-operative evaluation

Trabalho Final do Curso de Mestrado Integrado em Medicina, Faculdade de Medicina, Universidade de Lisboa, 2021Com o envelhecimento da população, a necessidade da cirurgia da catarata está aumentando. Em geral, é considerada uma cirurgia de elevado sucesso e com ótima relação custo-benefício. A tecnologia de lentes intraoculares (LIOs) está avançando à medida que os objetivos da cirurgia de catarata estão se tornando mais exigentes. Vivemos numa era digital e os estilos de vida dos pacientes são diferentes dos de há 15 anos atrás. A idade da reforma é mais avançada do que antes, o que significa mais horas de trabalho. Além disso, os pacientes têm mais expectativas sobre a sua visão e frequentemente desejam a independência dos óculos após a cirurgia de catarata. Eles não esperam nenhum resultado insatisfatório. Atualmente, em consultas, os oftalmologistas contam com dados subjetivos sobre o comportamento e o estilo de vida do paciente para avaliar as necessidades refrativas, a seleção do procedimento e a escolha das LIOs. Será que a tecnologia Vivior fornecerá dados objetivos para que os cirurgiões selecionem a solução refrativa mais adequada de acordo com as necessidades dos pacientes e seu estilo de vida? O Visual Behavior Monitor (VBM) consiste em sensores que medem a distância, luz ambiente, orientação da cabeça e movimento. É colocado nos óculos e regista os dados de atividade diária do paciente por 3-5 dias. Informações objetivas sobre a distribuição de distâncias visuais ajudam os oftalmologistas a compreender o estilo de vida e as necessidades de visão dos pacientes. Portanto, é possível escolher a melhor solução de LIO para o paciente. Com o Vivior Monitor, os pacientes terão uma expectativa mais realista do que sua solução de visão personalizada pode alcançar. O objetivo deste trabalho é ter uma melhor compreensão das distâncias de trabalho dos pacientes e melhorar a visão funcional após a cirurgia de catarata com base em numa abordagem pré-operatória mais objetiva.Due to the ageing of our population, the need for cataract surgery is increasing. It is generally considered to be a highly successful and cost-effective surgery. The technology of intraocular lenses (IOLs) is advancing as the objectives of the cataract surgery are becoming more embracing. We live in a digital era and patients’ lifestyles are different from 15 years ago. The retirement age is more advanced than before meaning more working hours. In addition, patients have more expectations about their vision and frequently desire the spectacle independence after cataract surgery. They do not expect any complication or unsatisfactory result. Nowadays, in consults eye care providers rely on subjective behavioral data about the patient lifestyle to assess refractive needs, selection of procedure and choice of IOLs. Will Vivior technology provide objective data for surgeons to select the best fit refractive solution according to patients needs and their lifestyle? Visual Behavior Monitor (VBM) consists of sensors measuring the distance, ambient light, head orientation and motion. It is clipped to prescription or clean spectacles and records the patient’s daily activity data for 3-5 days. Data processing is through machine learning algorithm. After downloading the data to the application, we can access our patient measured personal profile. Objective information about the distribution of visual distances helps eye care providers to understand patients’ lifestyles and vision needs. Therefore, it is possible to choose the best IOL solution for the patient. With Vivior Monitor patients will have a more realistic expectation of what their personalized vision solution can achieve. The objective of this work is to have a better understanding of the patients’ working distances and improve functional vision after cataract surgery based on a more objective pre-operative approach

Profiling the two most populous generations of the PIIGS countries in the workplace based in online consumption of cultural contents

The technological advances and the massive use of the Internet have led to the emergence of new business models based on the access online. One of the industries that most visibly had to adapt to the new reality was the production and dissemination of cultural contents, preparing for a consumer that is already native or casual digital. However, the new business model, especially, the one which implies access paid to cultural content, namely music, movies, TV series, images and news, does not still show a great success. In order to understand how the consumers of the generations X and Y (Millennials), from countries with unfavorable economic conditions, known as PIIGS, have adhered to the reality of online consumption of cultural content. The results from the Flash Eurobarometer 437: "Internet users' preferences for online accessing content" show the existence of three groups of consumers, and only one of them has a propensity to access paid content. Thus, by knowing the profiles of these three groups of consumers, it is possible to direct marketing campaigns tailored to each of them and to evaluate possible ways to convert consumers that only use of free services into consumers of paid services.info:eu-repo/semantics/acceptedVersio

The importance of participation in student organizations for soft skills development

The importance of developing transversal skills in a student's academic career arises mostly from the new demands of the labor market. Performance and competency management issues in organizations have changed in recent years. Hard skills used to be fundamental, but the paradigm has changed, and today something different is needed that keeps people in line with the demands of the world we live and work in, and increasingly facilitates the necessary interaction with other people. This is so called soft skills. As such, it is necessary to understand the level of adaptability of the higher education teaching model in view of this whole new labor market paradigm. Students' participation in Student Organizations enables them to further develop the skills sought by employers by engaging in different challenges and activities and especially through the level of commitment given to each of their responsibilities. This research aims to gather theoretical grounding on the topics described above and at the same time, through an online survey, obtain a personal opinion of several individuals with experience and active participation in student organizations, during their academic course. Thus, it has become evident, both through literary review and data collection, that participation in Student Organizations is increasingly important and should be valued by employers, given their ability to further develop than the teaching model of higher education, the skills required by the labor market.A importância do desenvolvimento de competências transversais no percurso académico de um estudante surge, maioritariamente, das novas exigências do mercado de trabalho. As matérias da gestão do desempenho, performance e do desenvolvimento de competências dos colaboradores nas organizações têm vindo a alterar-se nos últimos anos. Antes, as hard skills eram fundamentais, no entanto atualmente é necessário algo que mantenha as pessoas em linha com as exigências do mundo em que vivemos e trabalhamos, e que facilite, cada vez mais, a necessária interação com os outros. A tudo isto dá-se o nome de soft skills. Como tal, é preciso perceber o nível de adaptabilidade do modelo de ensino do Ensino Superior face a todo este novo paradigma do mercado de trabalho. A participação dos estudantes em Organizações Estudantis permite-os desenvolver, ainda mais, as soft skills, através do envolvimento em diferentes desafios e atividades e principalmente através do nível de compromisso dado a cada uma das respetivas responsabilidades. Esta investigação, tem como objetivo recolher fundamentação teórica sobre os temas acima descritos e ao mesmo tempo, através de um inquérito online, obter um parecer pessoal de diversos indivíduos com experiência e participação ativa em organizações estudantis, durante o seu percurso académico. Através deste estudo, torna-se evidente que a participação em Organizações Estudantis é cada vez mais importante e deve ser valorizada pelos empregadores, tendo em conta a capacidade que estas possuem em desenvolver, ainda mais do que o modelo de ensino do Ensino Superior, as competências exigidas pelo mercado de trabalho

On the induction of the four-dimensional Lorentz-breaking non-Abelian Chern-Simons action

A four-dimensional Lorentz-breaking non-Abelian Chern-Simons like action is generated as a one-loop perturbative correction via an appropriate Lorentz-breaking coupling of the non-Abelian gauge field to the spinor field. This term is shown to be regularization dependent but nevertheless it can be found unambiguously in different regularization schemes at zero and finite temperature.Comment: accepted version in Physical Review

Lisbon Participatory Budgeting Success. Assessing the Impact of Participatory Budgeting on Solving Citizens´ Problem in Lisbon Parishes

Dissertation presented as the partial requirement for obtaining a Master's degree in Information Management, specialization in Knowledge Management and Business IntelligenceThis master's thesis explores the impact of participatory budgeting (PB) on problem-solving within Lisbon Parishes, specifically examining the relationship between implemented PB projects and citizen complaints. Despite the overarching goal of PB to address community issues, its efficacy in problem resolution has remained uncertain. The study categorizes parishes based on success rates, revealing varying levels of impact. Results indicate positive outcomes in 54% of parishes, with distinct success in specific topics and parishes. However, the study acknowledges limitations, including a limited number of complaints and an incomplete understanding of complainer archetypes. The research underscores the importance of increased complaints and a broader participant profile for enhanced effectiveness in participatory budgeting. Additionally, the study establishes predictability in identifying winning projects through critical variables such as value, votes, complaints, number of residents, and education. The inclusion of residents and educational indicators further refines predictive accuracy. Furthermore, the study introduces the innovative use of concentration curves, classifying parishes into four segments based on success rates, where the 1st have 4 parishes. This novel approach provides a nuanced understanding of the distribution of PB impact across different parishes. The comprehensive analysis contributes to a deeper understanding of Participatory Budgeting, civic engagement, and the local context in Lisbon. The research calls attention to the importance of comprehensive data, diverse participant profiles, and increased public engagement in PB processes to foster successful problem-solving initiatives
