Abstract
The internet massification and e-commerce growth that have been driven by “millennials” and the coronavirus pandemic cannot remain indifferent to luxury brands. These brands have had to adapt to e-commerce and develop an online shopping experience which satisfies its customers, so that they repeat purchase. Therefore, the main objective of this research is to understand the main impacts of shopping experience on luxury brand websites on satisfaction and loyalty. A model which analyzes the relationship between the three constructs was developed and information was gathered through an online survey, from which resulted 356 valid answers. Through the analysis of data collected and using a structural equation model, using SmartPLS software, we realized that online shopping experience is positively related to satisfaction. Loyalty, in turn, is positively affected by brand satisfaction. This study makes an important contribution to luxury brands and to people in charge of marketing and online platforms selling luxury goods. It helps brands understand that enhancing online shopping experience can positively impact satisfaction and loyalty levels. © 2023, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.

Abstract
INTRODUÇÃO: De forma a contribuir para a diminuição da incidência e prevalência das doenças relacionadas com os hábitos alimentares, implementou-se o Projeto de Otimização das Dietas Escolares que pretende contribuir para uma oferta alimentar escolar alinhada com as premissas de uma alimentação saudável. OBJETIVOS: Comparar qualitativa e quantitativamente a oferta alimentar escolar referente à refeição do almoço considerando os modelos de gestão direta e concessionada. METODOLOGIA: Estudo observacional de desenho transversal. O Projeto de Otimização das Dietas Escolares, implementado em 34 escolas do ensino público do distrito de Viana do Castelo, tem como objetivo garantir a oferta de refeições variadas, normoenergéticas, nutricionalmente equilibradas e que garantam os critérios de higiene e segurança alimentar. Analisaram-se dados correspondentes a uma avaliação mensal de cada escola, entre 2014 e 2019. RESULTADOS: Os refeitórios com gestão direta cumpriram maior percentagem (82%), em mediana, de critérios qualitativos do Projeto de Otimização das Dietas Escolares, relativamente aos de gestão concessionada (p = 0,022). Todos os refeitórios com gestão direta cumpriram a periodicidade de oferta de peixe rico em ómega-3 (?3) exigida. Estes utilizaram uma maior quantidade de gordura e gordura saturada comparativamente aos de gestão concessionada (p = 0,030 e 0,040, respetivamente). O contrário ocorreu na oferta de fibra (p = 0,016). CONCLUSÕES: Considerando a avaliação qualitativa, os refeitórios com gestão direta cumpriram melhor os critérios do Projeto de Otimização das Dietas Escolares e ofereceram peixe rico em ?3 com maior periodicidade, relativamente aos com gestão concessionada. Quantitativamente, os refeitórios com gestão concessionada ofereceram refeições com menor quantidade de gordura e gordura saturada e maior quantidade de fibra.

Abstract
The use of technology applied in sports comes each year becoming a great tool to help athletes train. Moreover, the post-pandemic world is undergoing dramatic changes in the way of thinking and acting, with new ways of exercising emerging, but without leaving home. Thus this paper describes the development of a platform for training, focusing on Kendo practitioners (Japanese fencing) using virtual reality tools to allow athletes and training the distance. Through the use of a HMD (Head Mounted Device), kendokas will be able to practice blows and improve their reflex by a gamified experience in a virtual environment. © 2023 by SCITEPRESS – Science and Technology Publications, Lda.

Abstract
Slight variations in user interface response times can significantly impact the user experience provided by an interface. Load testing is used to evaluate how an application behaves under increasing loads. For interactive applications, load testing can be done by directly calling services at the business logic or through the user interface. In modern web applications, there is a considerable amount of control logic on the browser side. The impact of this logic on applications' behaviour is only fully considered if the tests are done through the user interface. Capture reply tools are used for this, but their use can become costly. Leveraging an existing model-based testing tool, we propose an approach to automate load testing done through the user interface.

Abstract
In recent years, several regulatory initiatives have been carried out at the European Commission level to ensure the ethical use of Artificial Intelligence, including the General Data Protection Regulation, Data Governance Act, or the Artificial Intelligence Act. However, there is also a need for technological solutions that effectively enable the implementation of this regulation in a realistic and efficient way. The main goal of this work is to propose and implement such a technological solution, relying on the notion of observability. The hypothesis is that a set of ethics metrics can be implemented along a domain-agnostic Data Science/Artificial Intelligence pipeline. These metrics, when observed in real time, will allow not only to assess the level of compliance of the pipeline with ethics standards at different levels, but also allow for a timely reaction by the organization when the data, the model or any other artifact in the pipeline exhibits undesired behavior. In this way, some of the most important ethical principles of AI are guaranteed: responsibility and prevention of harm. This work aims to identify a large group of ethics metrics, implement them, map them onto the different stages of a typical Data Science / AI process, and determine whether the presence of these metrics ensures or contributes to the development of AI solutions that can be considered ethical according to the latest European regulation.
