Relatório de Estágio na NML Turismo
Publication . Costa, David João Duarte; Oliveira , Fernanda Maria Fernandes; Eurico , Sofia Teixeira
Este relatório diz respeito ao estágio curricular, realizado em contexto empresarial na entidade NML Turismo, para a finalização do Mestrado em Gestão e Sustentabilidade em Turismo, da Escola Superior de Turismo e Tecnologia do Mar, do Politécnico de Leiria.
O relatório tem como tema principal o papel das certificações na sustentabilidade dos projetos turísticos. Será possível constatar que apesar das certificações trazerem vários benefícios para as entidades, existe uma saturação de oferta no mercado, com muitas certificações especializadas em diferentes aspetos da sustentabilidade, mas poucas a apresentar uma abordagem diversificada e equilibrada. Acresce que a componente prática do relatório demonstra que existe uma falta de representatividade dos diferentes Objetivos do Desenvolvimento Sustentável (ODS).
É apresentada uma ferramenta que agrupa os critérios do Rótulo Ecológico e Green Key, com a introdução de critérios adicionais, relacionando-os com o Programa Empresas Turismo 360. O objetivo é ajudar a NML Turismo, uma empresa de consultoria, a sistematizar o seu trabalho na sustentabilidade, e a promover projetos capazes de se adaptarem a todos os ODS.
Effects of a Workplace Exercise Program on Stress, Burnout, and Quality of Life in Radiologic Technologists: A Randomized Controlled Trial
Publication . Ramalho, Pedro; Nunes, António; Silva, Fernanda M.; Ramalho, André; Flores, Gonçalo; Monteiro, Diogo; Duarte-Mendes, Pedro
Background/Objectives: Radiologic technologists are frequently exposed to occupational stressors that heighten the risk of burnout, compromising well-being and job performance. Workplace exercise programs have been identified as promising strategies to enhance physical and mental health across occupational groups; however, robust experimental evidence among radiologic technologists remains limited. This study aimed to evaluate the effects of a structured workplace exercise program on perceived stress, burnout, and quality of life among radiologic technologists. Methods: A small-scale randomized controlled experimental study was conducted with 19 radiologic technologists from the Local Health Unit of Castelo Branco, Portugal. Participants were randomly assigned to an experimental group (n = 10, age mean = 43.8 ± 9.92 years old) or a control group (n = 9, age mean = 48.2 ± 7.86 years old). The intervention consisted of a six-week workplace exercise program conducted during work hours, comprising sessions three times per week, twice per day. Each session lasted approximately 15–20 min and included balance, stretching, and light resistance exercises. Outcomes were assessed pre- and post-intervention using the Perceived Stress Scale, the Copenhagen Burnout Inventory, and the WHOQOL-BREF. Results: The experimental group showed significant reductions in perceived stress (p = 0.013, d = −0.697 (−1.6–0.206) [moderate]) and in personal (p = 0.004, d = −0.834 (−1.748–0.08) [moderate]) and work-related burnout (p = 0.026, d = −0.756 (−1.664–0.151) [moderate]), as well as improvements in the physical (p = 0.046, d = 0.592 (−0.303–1.488) [small]) and environmental (p = 0.032, d = 0.991 (0.062–1.92) [moderate]) domains of quality of life. No significant changes occurred in the control group. Conclusions: These preliminary findings suggest that a brief, low-cost workplace exercise program may reduce stress and burnout and improve quality of life among radiologic technologists. These findings support the integration of structured physical activity into healthcare work settings as a feasible, preventive, and health-promoting strategy.
Liquid jobs and precarious workers. The Welfare State under pressure
Publication . Valadas, Carla
This article is inspired by one of Zygmund Bauman’s powerful metaphors, the concept of liquid, to interpret the present configuration of jobs and ongoing changes in individuals’ relationship with work. The later materialize in a time when welfare states’ role is going through a process of transformation itself. The sociological framework informing the article is anchored in a Southern European country, Portugal, with an idiosyncratic work and welfare state trajectory. It is argued that, in the liquid phase of our social reality, forms of inclusion into the labour market, such as the ones disseminated through public (active) employment policies, entrap individuals in unstable and insecure forms of employment.
Advanced Biofabrication Strategies for Skin Regeneration and Repair
Publication . Pereira, Rúben F.; Barrias, Cristina C; Granja, Pedro L; Bártolo, Paulo J.
Skin is the largest organ of human body, acting as a barrier with protective, immunologic and sensorial functions. Its permanent exposure to the external environment can result in different kinds of damage with loss of variable volumes of extracellular matrix. For the treatment of skin lesions, several strategies are currently available, such as the application of autografts, allografts, wound dressings and tissue-engineered substitutes. Although proven clinically effective, these strategies are still characterized by key limitations such as patient morbidity, inadequate vascularization, low adherence to the wound bed, the inability to reproduce skin appendages and high manufacturing costs. Advanced strategies based on both bottom-up and top-down approaches offer an effective, permanent and viable alternative to solve the abovementioned drawbacks by combining biomaterials, cells, growth factors and advanced biomanufacturing techniques. This review details recent advances in skin regeneration and repair strategies, and describes their major advantages and limitations. Future prospects for skin regeneration are also outlined.
Optimization of Anti-Spam Systems with Multiobjective Evolutionary Algorithms
Publication . Basto-Fernandes, Vitor; Yevseyeva, Iryna; Méndez, José R.
In this paper anti-spam filtering is presented as a cumbersome service, as opposed to a software product perspective. The huge human effort for setting up, adaptation, maintenance, and tuning of filters for spam detection in anti-spam systems is explained. Choosing the best importance scores for the spam filters is essential for the accuracy of any rules based anti-spam system, and is also one of the biggest challenges in this research area. Optimal filters score settings for Apache SpamAssassin project (the most widely adopted anti-spam open-source software) is addressed. In addition to a survey done on single/multi-objective optimization research in this area, we also present a study for filters score setting using multiobjective optimization based on two most representative evolutionary algorithms, NSGA II and SPEA2. Problem description, simulation and results analysis is done for SpamAssassin public mail corpus which is widely used for benchmarking purposes.
