Introduction: Hypoestrogenism is the main characteristic of female aging. It promotes significant changes in body composition, both in fat mass as in lean body mass, leading to a decrease in muscle strength and physical performance. Objective: The aim of this study was to test whether menopausal status and hormone levels are associated with muscular strength and physical performance in middle-aged women. Methods: In a cross-sectional study it was collected sociodemographic data, gynecological history, anthropometric and biochemical measures in women aged 40 to 65 years in Parnamirim-RN. The menopause status (pre, peri and post menopause) was determined by menstrual history. All women underwent three dimensions of physical performance assessment: handgrip dynamometry, gait speed and chair stands test - Short Physical Performance Battery (SPPB). Categorical data were presented as absolute and relative frequencies. Quantitative data were showed as mean and standard deviation and the normality of distribution was verified with Kolmogorov-Smirnov (KS) test. Biochemical measures of estradiol and follicle-stimulating hormone (FSH) were transformed to log10. ANOVA with Tukey post-test for comparison of variables between the groups pre, peri and post-menopausal was performed and then multiple linear regression analyzes. Results: Two hundred and seventy eight women aged 50.2 (±5.58) years composed this study, being 50 women in premenopausal status (18%), 122 in perimenopausal (43.9%), and 106 postmenopausal stage (38.1%). The groups were different in age (p=0.001), marital relationship duration (p <0.001), number of pregnancies (p=0.001) and parity (p=0.001). Differences in biochemical measures were observed among the groups: estradiol (p<0.001), FSH (p<0.001), total cholesterol (p=0.001). There were no differences in gait velocity between menopausal status. Values in mean of grip strength decreased by postmenopausal women to perimenopausal and premenopausal ones (24.5 ± 5.1, 25.6 ± 5.4, 26.9 ± 4.9 for post-stage, pre and peri menopausas, respectively, p = 0.02) and the performance of chair stands test was better in premenopausal women compared with that in peri and postmenopausal status (p = 0.02). In multiple linear regression for muscle strength, the variables that remained were: age, estradiol and somatic symptoms measured by Menopause Rating Scale-MRS (R2=0.15). While for the xiv chair-stands test the predictors were number of births and FSH values (R2=0.04). Conclusion: There is a relationship between the stages of menopause and muscle performance in measures of grip strength and sit-up test and these are influenced by the fall of estrogens levels. Data suggest that the decrease in muscle strength and physical performance already appear in the transition to menopause stage, pointing to the need for more research in this area and appropriate preventive interventions

The childhood cancer is characterized by a predominance of hematogenic and lymphatic system neoplasm, although a fTequency of the central nervous system tumors and sarcomas are widely common. Particularities of many childhood cancers and the adverses effect of the antineoplastic agents can change radically the oral environrnent and predisposes to the risk of oral complications. This study assessment clinically the oral health of 40 children on treatment for different types of malignant neoplasm with age range of O to 1S years old (Group I) and compared to 38 nonnal children in the same age range (Group lI). The results shown that nonnal patients had a gingival bleeding index (GBI) and caries experience minar than patients of Group lI, the visivel plaque index (VPI) was lightly higher in patients of Group 1. There was not difference statistically significant in the variables. Sixteen patients of Group I developed together 61 oral complications with predominance of mucositis, followed by spontaneous oral bleeding, candidiasis and xerostomy, that complication were most commons in patients with systemic neoplasm. Its was concluded that patients submitted to antineoplastic therapy with poor oral health had a higher risk to develop oral complications

Oral squamous cell carcinoma (OSCC) is the most common malignancy in oral cavity and human papillomavirus (HPV) may have an important role in its development. The aim of this experiment was to investigate the HPV DNA and viral types in 90 cases of OSCC. Moreover, a comparative analysis between the cases of OSSC with and without HPV DNA was performed by using cell cycle markers p21 and pRb in order to detect a possible correlation of these proteins and HPV infection. DNA was extracted from paraffin embedded tissue and amplified by PCR (polymerase chain reaction) with primers PCO3+ e PCO4+ for a fragment of human β-globin gene. After this procedure, PCR for HPV DNA detection was realized using a pair of generic primers GP5+ e GP6+. Immunohistochemical study was performed by streptoavidin-biotin technique and antibodies against p21 and pRb proteins were employed. Eighty-eight cases were positive for human β-globin gene and HPV DNA was found in 26 (29.5%) of then. It could not be detected significant correlation between HPV and age, sex and anatomical sites of the lesion. The most prevalent viral type was HPV 18 (80.8%). Regarding the immunohistochemical analysis, it was detected significant association between HPV presence and pRb immunoexpression (p=0,044), nevertheless, the same was not observed in relation to p21 protein (p =0,416). It can be concluded that the low detection of HPV DNA in OSCC by the present experiment suggests a possible role of the virus in the development and progression in just a subset of this disease

This research has resulted of investigations appeared from our work experience as psychologist in a prison of the state Rio Grande do Norte. It deals with the meeting with prisoner in the search for the rescue of the human being dignity, discovering the being that finds annulled by backwards of the prison. The current debate on the prisoners in Brazil has as focus the creation of efficient strategies in the combat to the criminal acts, not being worried in understanding the historical and social conditions in the context in which such acts develop. Our objective was to reach an understanding of the experience of the prisoner in the situation of freedom deprivation in Natal (RN) city. Its significant social relevance meets in emphasized thematic which intends to be revealing of the not-said one of these citizens. The epistemological space and the vision of adopted human being support in the humanist ideas of the Centered Approach in the Person and construct self, central nucleus of the personality theory proposal by Carl Rogers. We opt to the phenomenological method as way of access to the singularity of the experience of each one of the participants, supporting us in the strategy of the narrative as expression of the lived world. The results had pointed that the investigated experience is through suffering, that is, the way to be in the world of prisoner in the situation of freedom deprivation is felt by him/her as difficult to support. This reality is had by him/her as difficult to control, having a negative emotional repercussion for the self, leading the citizen to the alienation of his/her existential flow in these circumstances. The reflections produced in this work take us to consider that the punishment practices on behalf of a normalization of the behavior, linked to the recovery idea, do not meet to the intention of the arrests, that come demonstrating to the inefficacy of the objectives shown in the law as well as the loss of the human being dignity

Our professional everyday life, as a psychologist, we often come across the narrative made by women of a permanent suffering experience in loving and sexual relation. This checking created questions which indicated to the questioned experience singularity, taking into account the historic and cultural aspects (genre and romantic love) that seemed to permeate such an experience. The conduction given to this research was guided by the following question: how is to the woman the experience of going on suffering on loving and sexual relation? Therefore, the objective was to understand that experience. Were carried out with six women that were living the experience which intend to investigate. The narrative, in according to the purposal by Walter Benjamin was the access tool to the experience. The narrative analysis shows the singularity of constant suffering experience on loving relation as well as common aspects. It is remarkable the presence of relative questions to the genre and romantic loving dimension, influencing the way as the interviewed women perceive themselves on the existence and realize the loving suffering which experience. Women reveal several ways of expressing and perceiving to the loving suffering which is common the manifestation of several physical and psychic symptoms. The most participants had experiences of protected familiar contact of feeling development of low self-esteem, disability, unstableness and fear. We realize that the suffering of interviewed women, on loving relation, it revels, above all, a way of being in the world, perveiving themselves, marked by solitude fear, lovelessness, leading the life itself giving origin to the lifestyle and of really new loving. Thus, we emphasize the importance of greater engagement of professionals and institutions which deal with the thematic this research in order to develop actions that consider its complexity. We also emphasize new reflections about the loving suffering so that different sense possibilities can emerge propitiating a greater comprehension of human subjectivity

This study aims to understand as the children who show expressive behaviors of antisocial trends at Núcleo de Ação Social da Praia do Meio in Natal-RN city, linked to Secretaria Municipal do Trabalho e Assistência Social-SEMIT, which experience the relation with the social educator in role of caregiver. This matter was investigated within an interpretation and approach qualitative view of the social phenomena, using the Thematic Analysis technique of drawings and stories which express the relation with the caregiver gotten in sessions of playful interactions between child and researcher in order to understand the child experiences with the social educator. The used theoretical referential is by D. W. Winnicott who associates the social trend to a failure of environment in child holding. The subjects expressed the need of a firm and protective environment and they look for this in NASPM educators. Moreover, they show as solitude and vulnerability take part their lives due to the lack of emotional holding on family that favors the involvement with violent groups. But, it is worth pointing out that the children value the Nucleus environment when has offered them a safe holding which can be positive the established linking with it. Such conclusion points out to the possibility, recognized theoretically, that exists from these children to resume the way of healthy development

The elderly population growth in Brazil and in the world is an incontestable reality, arising from a significant declining rate in mortality and fertility, resulting from the remarkable improvements in the quality of life of the people. Associated with the introduction of new technologies in the medical area, these issues have been highly contributing for the increase of the population longevity. The numbers of the elderly in Brazil and in the world show female population predominance within the aging segment, a phenomenon known as the feminisation of the old-age . Aging, therefore, is nowadays one of the primary issues and that has been mobilizing the Brazilian s society, since the development raised from this new reality brought with it enormous challenges and complex social implications which are already felt in the daily lives of the societies. My work experience among some age groups has shown that aging is a much differentiated process which has instigated my interest in understanding why aging has to face an overwhelming and painful experience for some people and enriched and full of signification for others. Overviewing, this research aimed to understand the aging development through the analysis of the processes of signification and production of meaning that permeate the aging and the subjective well-being of three aged women participants of the Project Health and Citizenship on Third Age /CEFET-RN, that evidenced attitudes and behaviors concerning the integration and the activity toward the elderly population. The methodological strategy used was History of Life, starting from collecting data based on deep interviews. The analysis of data evidenced that the elderly well-being is a unique and distinct meaningful experience for each person, concerning each story of their lives within differentiated social, cultural, economic context, from this perspective one can demystify the concept of that aging occurs in a homogeneous way for everyone, everywhere and with the same rhythm. The narratives presented in this research showed the human development as being a dialectic, discursive and interactionist process which extends throughout the adult life and continues to the aging life. The guarantee that development and aging are a parallel phenomenon always in interdependence on the preceding phases of live, are corroborated within the studies. This present study confirms that the elderly population can be a phase of growth, personal realization and continued development, without disrespecting the heterogeneous and the subjectivity of the person who ages. Notifying those healthy and well-succeeded aging experiences, this issue has the intention to contribute to demystify the concept of aging as a social problem, illness needed to be treated, and the stereotypy of the elderly being dependent and unproductive

An interesting development in surfactants science and technology is their application as corrosion inhibitors, since they act as protective films over anodic and cathodic surfaces. This work aims to investigate the efficiency of saponified coconut oil (SCO) as corrosion inhibitor and of microemulsified system (SCO + butanol + kerosene oil + distilled water), in saline medium, using an adapted instrumented cell, via techniques involving linear polarization resistance (LPR) and mass loss coupons (MLC). For this, curves of efficiency versus SCO concentration (ranging between 0 and 75 ppm) have been constructed. According to the obtained results, the following efficiency levels were reached with OCS: 98% at a 75 ppm concentration via the LPR method and 95% at 75 ppm via the MLC method. The microemulsified system, for a concentration of 15 ppm of SCO, obtained maximum inhibition of 97% (LPR) and 93% (MLC). These data indicate that it is possible to optimize the use of SCO in similar applications. Previous works have demonstrated that maximal efficiencies below 90% are attained, typically 65% as free molecules and 77% in microemulsified medium, via the LPR method in a different type of cell. Therefore, it can be concluded that the adapted instrumented cell (in those used methods) showed to be an important tool in this kind of study and the SCO was shown effective in the inhibition of the metal

This study is about the users' experiences of the services offered by League Against Câncer that are in treatment of breast cancer, focusing on how the health/illness process develops. It is distinguished, in this context, the National Politics of Health, approaching the sprouting, implantation and consolidation process of the Unified Health System and its shocks on the installment of health services to the low-income population as a legit right from Citizen Constitution. It has as an objective to analyze how the social-economic extract of these women intervenes with such process, the aspects who involve the cancer while a pathology, approaching the signals, symptoms, forms of prevention, diagnosis, among other aspects that configure themselves as important points to the understanding of these experiences, since the diagnosis, treatment and control phases. The research was carried out with 25 women, between the months of January and February of year of 2005. The used technique was the scriptstructured interview, whose universe was defined through intentional sample. The following distinguishes as a result of the research: The majority of the women has its origins on the interior of the state, possesses a familiar income from one to three minimum wages and didn't make any kind of prevention before diagnosis, currently make treatment, beyond other aspects. It becomes necessary posterior studies on this social problematic, with respect to the personal, professional, familiar and social daily behavior of these women. It is worth mentioning that the role of the social assistant in the developed work with these women, understanding all the impediments associated with such experiences, as well as giving information about the rights of the patients with cancer, conquered through the years

The software systems development with domain-specific languages has become increasingly common. Domain-specific languages (DSLs) provide increased of the domain expressiveness, raising the abstraction level by facilitating the generation of models or low-level source code, thus increasing the productivity of systems development. Consequently, methods for the development of software product lines and software system families have also proposed the adoption of domain-specific languages. Recent studies have investigated the limitations of feature model expressiveness and proposing the use of DSLs as a complement or substitute for feature model. However, in complex projects, a single DSL is often insufficient to represent the different views and perspectives of development, being necessary to work with multiple DSLs. In order to address new challenges in this context, such as the management of consistency between DSLs, and the need to methods and tools that support the development with multiple DSLs, over the past years, several approaches have been proposed for the development of generative approaches. However, none of them considers matters relating to the composition of DSLs. Thus, with the aim to address this problem, the main objectives of this dissertation are: (i) to investigate the adoption of the integrated use of feature models and DSLs during the domain and application engineering of the development of generative approaches; (ii) to propose a method for the development of generative approaches with composition DSLs; and (iii) to investigate and evaluate the usage of modern technology based on models driven engineering to implement strategies of integration between feature models and composition of DSLs

The work proposed by Cleverton Hentz (2010) presented an approach to define tests from the formal description of a program s input. Since some programs, such as compilers, may have their inputs formalized through grammars, it is common to use context-free grammars to specify the set of its valid entries. In the original work the author developed a tool that automatically generates tests for compilers. In the present work we identify types of problems in various areas where grammars are used to describe them , for example, to specify software configurations, which are potential situations to use LGen. In addition, we conducted case studies with grammars of different domains and from these studies it was possible to evaluate the behavior and performance of LGen during the generation of sentences, evaluating aspects such as execution time, number of generated sentences and satisfaction of coverage criteria available in LGen

This research aims to focus on the education problem, since its source of development is the Research Base: Teachers Training and Qualification of UFRN. Therefore, we seek guidance in the beliefs in sustainability to propose plausible alternatives to promote the education process of UFRN administration undergraduates in order to meet the demands of a market-oriented society, since the market trend is to evolve from environmental guided activities, and future administrators should be trained to meet those conditions. The need to develop an instrument capable of understanding the beliefs of undergraduates on the sustainability problem becomes the object of analysis. This research aims to develop a normative questionnaire to study administration students beliefs in sustainability. The complexity and sensitivity of this research required the integration of various methodological procedures. These proposals were made as follows: analysis and selection of literature, expert validation procedures and psychometric methods and statistics. As for the literature, types of sustainability were identified and categorized, such as: political, social, economic and environmental sustainability. However, it is understood that the educational type, although included in all of those, needed to be converted into another type to fit the theme, since education is believed to be the best way to raise awareness about sustainability. Thus, it was required the categorization of the types, which was defined using criteria such as: contexts, objectives, goals, pathways and hypotheses. The normative questionnaire was the guiding instrument to investigate the role of administration students, regarding the level of knowledge established and regulated by social educational context, especially by becoming a basic condition for carrying out research on beliefs. The study confirmed that the types of sustainability - political, social, economic, environmental and educational - for having institutionalized literatures as sources, in international and national levels, are representative in the identification of future administrators. Therefore, it is believed that the types of sustainability categorized to provide a characterization of sustainability include the structuring of knowledge for undergraduates. The economic and political types, however, were not as representative with respect to their typicality and polarity indices as the educational, environmental and social ones. Although the beliefs of the undergraduates show how much they share ideas on all types, they present more identification with the educational and environmental types. Finally, it is expected that this instrument be subject to application in similar contexts so that it can ascertain whether such statements are part of the knowledge structure of future administrators from other institutions. Therefore, it is expected this strategy to strengthen the validation of the normative questionnaire
