A passagem à reforma : um estudo exploratório sobre mulheres profissionalizadas na sociedade portuguesa

RESUMO: Devido às mudanças políticas e sociais que ocorreram no passado, a proporção de mulheres activas no mercado de trabalho tem vindo a aumentar, e neste sentido, cada vez mais mulheres têm vindo a entrar na reforma. As recentes evoluções demográficas mostram um crescente envelhecimento populacional caracterizado por um aumento da proporção de pessoas idosas e pela sua maior longevidade. As mulheres são em número superior, no entanto, a realidade da mulher portuguesa reformada tem sido pouco avaliada sob o ponto de vista em que decorre esta transição. A passagem à reforma é um momento fulcral para conhecer como se adaptam os indivíduos a uma nova etapa da sua vida que é actualmente vivida por mais tempo, e que representa também a passagem para outra categoria social, a categoria de reformado. Condicionantes sociais, culturais e individuais, contribuem para modelar esta transição e o ajustamento à mesma. A reforma para as mulheres deverá corresponder a uma etapa com características únicas, devido às particularidades em termos profissionais e sociais que as distinguem dos homens. Pretende-se neste trabalho “dar voz” às mulheres portuguesas que tiveram uma carreira profissional e conhecer as suas experiências de transição para a reforma e a forma como vivem esta condição. Foram realizadas entrevistas em profundidade com mulheres portuguesas profissionais reformadas, cujos conteúdos foram analisados em torno das seguintes categorias: sentimentos vividos; planeamento e motivações para a passagem à reforma; relação com o trabalho; noção de si própria; gestão de tempo e organização quotidiana e interacções familiares e sociais.-------- ABSTRACT: Due to past political and social changes the number of women working actively in the labor market is growing. This implies that, more women are also entering in the retirement period. Recent demographic trends show an increasing ageing population, characterized by a higher proportion of elderly people, and a higher longevity. Women’s proportion outnumbers older men, yet the reality of Portuguese retired women has been poorly evaluated in regard to this transition process. Retirement transition is a crucial period to understand how individuals adapt to a new stage in their life, that is actually being enjoyed for a longer period and that also represents the transition to retiree’s social role. Social, cultural and individual conditions help to shape this transition and adjustment to it. Retirement for women should be an event with unique features, mostly because of the peculiarities in professional and social relationships, distinct from men. Through in-depth interviews, we explored how Portuguese women, who had a professional career, experience the retirement transition and how they live this new condition. The women’s narratives were analyzed within the following categories: experienced feelings, planning and motivation for retirement; notion of self; time management and daily organization; family and social interactions.

An Exercise Program Improves Health-Related Quality of Life of Workers

Low back problems are associated with decreased quality of life. Specific exercises can improve quality of life, resulting in better professional performance and functionality. The purpose of this study was to evaluate the effect of following a 21-month exercise program on the quality of life of warehouse workers. The population included 557 male warehouse workers from a food distribution company in Oporto, Portugal. Upon application of the selection criteria, 249 workers were deemed eligible, which were randomized into two groups (125 in the intervention group and 124 in the control group). Then, subjects were asked to volunteer for the study, the sample being formed by 229 workers (112 in the intervention group and 117 in the control group). All subjects completed the SF-36 questionnaire prior to beginning the program and on the 11th and 21st months following it. The exercises were executed in the company facilities once a day for 8 min. Data were analyzed using SPSS® 17.0 for Windows®. After 11 months of following the exercise program, there was an increase in all scores for the experimental group, with statistically significant differences in the dimensions physical functioning (0.019), bodily pain (0.010), general health (0.004), and rolephysical (0.037). The results obtained at the end of the study (21 months) showed significant improvements in the dimensions physical functioning (p = 0.002), rolephysical (p = 0.007), bodily pain (p = 0.001), social functioning (p = 0.015), role-emotional (p = 0.011), and mental health (p = 0.001). In the control group all dimensions showed a decrease in mean scores. It can be concluded that the implementation of a low back specific exercise program has changed positively the quality of life of warehouse workers.

Traumatic Clivus Epidural Hematoma: Case Report and Review of the Literature

BACKGROUND: Traumatic clival epidural hematoma is an extremely rare reported entity. CASE DESCRIPTION: We describe the case of a 26-year-old woman involved in a car accident who presented with a Glasgow Coma Scale score of 13, bilateral abducens palsy, bilateral numbness on the mandibular territory of the trigeminal nerve, and left hypoglossal palsy. Radiological examinations revealed a clival epidural hematoma. The patient was managed conservatively, with clinical improvement of her neurological condition. This is the first traumatic clival epidural hematoma reported in an adult. From a review of the literature, we found only 8 cases. CONCLUSION: The pathophysiology of these hematomas is still a subject of debate; occipitoatlantoaxial ligamentous instability may play a role in it. In one third of the cases, bilateral cranial nerve palsies were associated. Apparently, they have a benign outcome.

Life Cycle Assessment of the Hybrid Vehicle – Toyota Prius

Die Luftverschmutzung, die globale Erwärmung sowie die Verknappung der endlichen Ressourcen sind die größten Bedenken der vergangenen Jahrzehnte. Die Nachfrage nach jeglicher Mobilität steigt rapide. Dementsprechend bemüht ist die Automobilindustrie Lösungen für Mobilität unter dem Aspekt der Nachhaltigkeit und dem Umweltschutz anzubieten. Die Elektrifizierung hat sich hierbei als der beste Weg herausgestellt, um die Umweltprobleme sowie die Abhängigkeit von fossilen Brennstoffen zu lösen. Diese Arbeit soll einen Einblick über die Umweltauswirkungen des Hybridfahrzeuges Toyota Prius geben. Hierbei findet eine Gliederung in vier verschiedene Lebensphasen statt. Im Anschluss bietet die Sachbilanz die Möglichkeit die Umweltauswirkungen mit verschiedenen Antriebsmöglichkeiten und Brennstoffen zu vergleichen. Das Modell hat gezeigt, dass der Toyota Prius während der Nutzung einen hohen Einfluss auf das Treibhauspotenzial aufweist. Durch die Nutzung anderer Brennstoffe, wie beispielsweise Ethanol oder Methanol lassen sich die Auswirkungen am Treibhauspotenzial sowie der Verbrauch an abiotischen Ressourcen reduzieren. Vergleicht man die Elektromobilität mit der konventionellen, so ist festzustellen, dass diese Art der Mobilität die derzeit beste Möglichkeit zur Reduzierung der Umweltbelastungen bietet. Die Auswirkungen der Elektromobilität sind im hohen Maße abhängig von der Art des verwendeten Strommixes.

3D-nanostructured Au electrodes for the event-specific detection of MON810 transgenic maize

In the present work, the development of a genosensor for the event-specific detection of MON810 transgenic maize is proposed. Taking advantage of nanostructuration, a cost-effective three dimensional electrode was fabricated and a ternary monolayer containing a dithiol, a monothiol and the thiolated capture probe was optimized to minimize the unspecific signals. A sandwich format assay was selected as a way of precluding inefficient hybridization associated with stable secondary target structures. A comparison between the analytical performance of the Au nanostructured electrodes and commercially available screen-printed electrodes highlighted the superior performance of the nanostructured ones. Finally, the genosensor was effectively applied to detect the transgenic sequence in real samples, showing its potential for future quantitative analysis.

A Clinical Support System Based on Quality of Life Estimation

Quality of life is a concept influenced by social, economic, psychological, spiritual or medical state factors. More specifically, the perceived quality of an individual's daily life is an assessment of their well-being or lack of it. In this context, information technologies may help on the management of services for healthcare of chronic patients such as estimating the patient quality of life and helping the medical staff to take appropriate measures to increase each patient quality of life. This paper describes a Quality of Life estimation system developed using information technologies and the application of data mining algorithms to access the information of clinical data of patients with cancer from Otorhinolaryngology and Head and Neck services of an oncology institution. The system was evaluated with a sample composed of 3013 patients. The results achieved show that there are variables that may be significant predictors for the Quality of Life of the patient: years of smoking (p value 0.049) and size of the tumor (p value < 0.001). In order to assign the variables to the classification of the quality of life the best accuracy was obtained by applying the John Platt's sequential minimal optimization algorithm for training a support vector classifier. In conclusion data mining techniques allow having access to patients additional information helping the physicians to be able to know the quality of life and produce a well-informed clinical decision.

Summer Vacations not Only a Memory for Life, but Also a Rare Infection

Introduction: Rhinoscleroma is a rare, chronic, granulomatous disease that most frequently affects the upper respiratory tract, especially the nasal cavity and sometimes extends through the lower respiratory tract. Is associated with Klebsiella rhinoscleromatis, which is endemic in certain geographic regions namely Central America. The pathogenesis and risk factors remain unclear. Clinical case: We report a five years Old Portuguese boy, previously healthy, brought to the Emergency Department with epistaxis, without other accompanying signs or symptoms. The Otorhinolaryngologist (ORL) performed rhinoscopy and identified an intranasal bleeding mass. The MRI revealed an intranasal mass with extension to the ethmoid bone sinus, and performed biopsy. The histopathology was vital, making the diagnosis of Rhinoscleroma. The child had traveled abroad for the first time on vacations a year before to Dominican Republic. The bacteriologic exam identified a Klebsiella spp. sensible to the association of amoxicillin and clavulanic acid. Blood test performed excluded association of immunodeficiency. Since it’s a rare disease genetic study are under course. Monthly evaluation by ORL and pediatrician was performed which documented progressive reduction until total disappearing of the macro and microscopic lesion, and negative bacteriologic exam. Six months of antibiotic therapy were completed without any known secondary effects. The child remained asymptomatic up to the last visit, 3 months following treatment and has shown no evidence of recurrence. Conclusion: Globalization and free transit of people to areas far from origin countries here some rare diseases are endemic brings a new challenge to modern medicine. Sometimes vacations bring more than memories.
