Square stepping exercise: uma revisão

Many studies inform that with aging process there’s a drop, not only in the cognitive functions, but also in the functional fitness. This drop can damage the old people’s daily activities, making them lose their independence. These declines can be softened with the practice of physical exercises. So, the aim of this study is to develop a systematic review in the literature which is the quantity of lectures done using the Square Stepping Exercise, we use a follow keyword “Square Stepping Exercise”. We performed a search in the following databases: PUBMED, Portal de Periódicos CAPES, Google Acadêmico e Catálogo Athena (acervo da Biblioteca de todos os campus da UNESP). Those procedures were complemented for manual searches in the references of the found lectures, like the access to the curriculum vitae, plataforma Lattes. There were analyzed articles, in Portuguese and English. Language were selected 11 studies (2 monografies, 1 masters lecture, 1 experience relatorie, 1 book chapter and 6 articles). The references found had improvement in motor and cognitive aspects. With this review, it was concluded that the SSE showed itself as a useful method to get better and/or maintain the analyzed aspects. It’s also necessary new studies with different populations, tips of analyse, periods of time and other aspects

Um tempo para a literatura ou a vida entre o labirinto e a bússola

Since the priors, man has been trying to understand the concept of time. From myth to quantum physics, time is something that inspires reflections on our own lives. Do we exist in time or for time? Literature, a peculiar form of knowledge, deals with the experience of time in many ways. By avoiding categorizations, literature converges time and space in a dimension in which labyrinth and compass converge: at the reading time, in the reader’s space, in the universe of the book, where Cronos, Kairos, and their heir, by excellence, the literary word, constellate. In this way, in this essay, I discuss some aspects of the relationship between literature and time, or still, what literature can teach us about the time.

A crise na sociedade do trabalho e sua importância na contextualização dos conteúdos curriculares do ensino médio

This article has as objective to discuss some topics concerning the supposed crisis of the society of the work and its consequences for the debate in social sciences and also for the work category contextualization in the secondary school curriculum. As the work has represented an important explanation category for the classic social thought, the contemporary paradigm of deep metamorphoses in the world of the work and the advent of the new question (CASTELS, 1995; ROSANVALLON, 1995) backward the necessity to rethink the theoretical shades that base the interpretation of the social life on the current context, when the center position of the work is being questioned. Having taken some theoretical references from the sociology of the work, we search to delineate on a brief way the quarrel about the dimensions of the social and political phenomena these days and the importance of this debate on the contextualization of the secondary school curriculum contents.

Propriedade antioxidante de compostos fenólicos: importância na dieta e na conservação de alimentos

Living organisms are constantly subjected to the action of free radicals, which are one of the causes of oxidation reactions, because they have on free electron, what makes it very reactive. They are products of organism reactions or they are produced by exogenous factors, such as tobacco. Fatty acids are the most vulnerable target, and may suffer lipid peroxidation, what affects the cell structure. Cardiovascular diseases, cancer and diseases of aging are occurrence of these reactions in the organism related. The aliments are also subjected to suffer oxidation reactions, what make them unfit for consumption and decreasing the useful life. Synthetics antioxidants are used as aliments preservatives, but they present some toxicity for the organism. Studies for the utilization of natural antioxidants have gained more importance in recent decades, due to the conservation potential and low toxicity. Phenolics compounds are largely present at the vegetable kingdom and they present high antioxidant potential due to the neutralization and kidnapping of free radicals capacity. These compounds are used by the industry at the aliments conservation, specially the phenolics acids. The consumption of aliments rich in phenolic compounds, such as teas, wines and fruits are low incidence of degenerative diseases related. This study consists in a bibliographic revision that covers these compounds importance in diet and at the food conservation, and the methodologies and difficulties in the extraction process due to variety of molecules of this group.

Compostos antioxidantes e sua importância nos organismos

A large amount of external factors that can foster the emergence of free radicals in organisms has created a imminent need for understanding and technologies that enables the search of antioxidant componds and extraction of antioxidants from natural sources. These compounds have great potential for kidnapping free radicals which are highly harmful to organisms, being the principal responsible for the decrease in the shelf life of foods, and aging. These free radicals are also related to diseases such as AIDS, arthritis, diabetes, heart disease and others. Fruits and vegetables are true mines of compounds with antioxidant potential, its vitamins and phenolic compounds present an essential role in the nutrition of living beings acting as a defense against degradation of lipids and proteins, which indicates the importance of a diet rich in these nutrients, given that part of the antioxidant defenses of the body comes from the diet. This revision study aims to put in evidence the indispensable role of antioxidants in the survival of organisms.

A taxa de câmbio do Brasil é válida no longo prazo?

The objective of this study was to test the validity of the real exchange rate in the long run. For that five tests were performed based on equation, which relates to real exchange rate, international trade, domestic income. The main difference is that the tests when we are working with quarterly data, the parameters are significantly different from zero – i.e., the variables real exchange rate, international trade, domestic income and net exports on long term relationship – and, moreover, the signs are as expected. This implies that it is possible to increase exports with currency devaluation. Thus, based on data and tests that work we conclude that the exchange rate is an important instrument of trade policy, given that devaluations are valid even in the long term.

Políticas Industriais e de Ciência, Tecnologia e Inovação na Irlanda: ênfase em setores de alta tecnologia e comparação com o Brasil

From a theoretical foundation favorable to industrial policies, this paper intends to show the main policies followed by Ireland since the 1950s, with a special emphasis on those directed to Science, Technology and Innovation (S,T&I), FDI and high tech sectors, like software and biotechnology. We compare these policies with those used in Brazil, in a similar period, in order to have some hints for virtual transformations of current Brazilian policies. We conclude that the compromise of the State with the direction of the development and the continu-ity of industrial policies is very important to a solid building of comparative advantages in technologically dynamic sectors.

Formação de nomes deverbais nas Cantigas de Santa Maria

This research aims to present and discuss three morphophonological processes – juxtaposition, allomorphy of the verbal thematic vowel and gemination of similar vowels – which occurs in word formation involving the suffixes -çon and -mento in a corpus composed of 420 Cantigas de Santa Maria. The cases analyzed in this study occurred with nouns from verbs of the first, second and third conjugations. Through the analysis of these processes we conclude that the suffix -çon triggers more morphophonological processes than the suffix -mento. However, although the processes are very productive, we note that most of the names were formed from the juxtaposition of the suffixes - especially in nouns formed with -mento – which shows a tendency to regularity in the word formation with these suffixes.

Da invenção do vestibular aos cursinhos populares: um desafio para a orientação profissional

This article is based on the sociological and historical approach of the origin of the university entrance exams in Brazil and shows the preparatory courses (preps) expanding simultaneously as a strategy of the lower and middle classes to get their children into university. Thus, the paradox of an antipedagogical practice becomes an essential condition for students to have access to prestigious university courses, what justifi es the historical movement by the lower and middle classes to appropriate this practice.. We propose that measures are taken to improve the results of important affi rmative actions that aim to enable students to enter university, as well as highlight Professional Guidance as a necessary resource which constitutes a new challenge in this fi eld of action.
