A formação da identidade numa perspectiva educacional

Este trabalho procura elucidar alguns conceitos teóricos de identidade, como é entendida por diferentes autores, como nós a interpretamos e como o processo educacional influencia o desenvolvimento da identidade dos adolescentes. Para isso recorremos ao fenômeno da identificação, aos conflitos intra-psíquicos, particularmente no período da adolescência, e aos vínculos de integração espacial, temporal e social. Consideramos a identidade estruturada por três níveis fundamentais: pelas estruturas mais desenvolvidas da personalidade, caracterizada pela relação interpessoal, baseada nos mecanismos de projeção e introjeção; pelos mecanismos de identificação projetiva-introjetiva e pela persistência da fusão ou estrutura sincicial primitiva que caracteriza a sociabilidade sincrética. Partimos da concepção de identificação como a forma mais primitiva de ligação afetiva. Tomamos a conquista da identidade corporal e sexual como a base das demais identidades parciais. A formação da identidade como um todo, que pressupõe uma crise na adolescência, baseia-se na problemática mais específica da formação de uma identidade sexual. Enquanto a identificação se opera através de introjeções, a identidade resulta da oposição de identificações anteriores. O processo é dialético. Somos de opinião que a identidade é formada por processos eminentemente sociais. Uma vez formada, é mantida, modificada ou mesmo remodelada pelas relações sociais. Nossa preocupação centralizou-se no processo de formação de identidade, considerado em estreita relação çom a família, a escola e a sociedade e em contínua interaçao professor-aluno, ensino-aprendizagem. Tentamos detectar as influências da educação sistematizadas no processo de formação da identidade e em especial visualizar o papel do professor no referido processo, através de pesquisa de campo. Para isso elaboramos um questionário composto de duas partes. A primeira contendo dados de identificação do aluno, da família e da escola. A segunda, composta de 40 perguntas consideradas, inferencialmente, como indicadores dos vínculos de integração espacial, temporal e social. Os sujeitos de nossa pesquisa constituiram-se de 176 alunos, na faixa etária de 14 anos, masculinos e femininos, de 5ª e 8ª series, do ensino de 1º grau das escolas da rede estadual de Divinopolis, M.G., em 1978. A análise dos dados obtidos evidenciou o desenvolvimento de nossos sujeitos em termos de identificação com os grupos primários, predominando a dependência em nível infantil.

Associação entre a ingestão de macronutrientes e a obesidade abdominal com a doença arterial coronária

Introdução: A incidência da doença arterial coronária é uma das principais causas de morbidade e motalidade em diversos países e o estudo dos fatores de risco têm grande importância na prevenção e no tratamento dessa enfermidade. Entre outros fatores, a obesidade e a obesidade abdominal têm sido associadas com a maior incidência de DAC. A ingestão diária de nutrientes também pode estar relacionada com essa doença, porém, uma vez que a alimentação é complexa e contém diversos nutrientes, ainda não foi possível elucidar o impacto da alimentação no risco de desenvolver a doença arterial coronária. Objetivo: Avaliar a relação entre o consumo alimentar diário, a presença de obesidade abdominal e achados angiográficos de obstrução arterial em pacientes portadores de cardiopatia isquêmica, submetidos a cateterismo cardíaco. Métodos: Foi realizado um estudo transversal, com 284 pacientes submetidos a cateterismo cardíaco, da unidade de hemodinâmica de um hospital universitário. Foi avaliada a RCQ, o IMC, a ingestão alimentar diária através de um inquérito nutricional, a análise bioquímica do sangue e a avaliação do laudo do cateterismo cardíaco. Resultados: Dos pacientes avaliados, 172 indivíduos (60,6%) apresentavam alterações em uma ou mais artérias coronárias. A ingestão média diária de calorias foi de 2450,56 Kcal/dia. O consumo de proteínas foi em média 1,66 g/Kg/dia, de carboidratos foi de 3,83 g/Kg/dia e de lipídeos foi de 1,21 g/Kg/dia. A idade, o sexo masculino, os níveis séricos de triglicerídeos, o consumo de álcool e a glicemia em jejum foram estatisticamente significativos na análise multivariada. Conclusão: Nos pacientes avaliados, o consumo diário de calorias encontra-se adequado, porém a ingestão de proteínas, carboidratos e lipídeos estão inadequados. Em relação aos fatores de risco para DAC, as mulheres apresentaram maior associação para desenvolver a síndrome metabólica do que os homens.

Caracterização estrutural e avaliação das atividades farmacológicas da fucana B extraída da alga Dictyota menstrualis

Seaweeds are a major source of biologically active compounds . In the extracellular matrix of these organisms are sulfated polysaccharides that functions as structural components preventing it against dehydration. The fraction 0.9 (FucB) rich in sulfated fucans obtained from brown seaweed Dictyota menstrualis was chemical characterized and evaluated for pharmacological activity by testing anticoagulant activity, stimulatory action on the synthesis of an antithrombotic heparan sulfate, antioxidant activity and its effects in cell proliferation. The main components were FucB carbohydrates (49.80 ± 0.10 %) and sulfate (42.30 ± 0.015 %), with phenolic compounds ( 3.86 ± 0.016 %) and low protein contamination ( 0.58 ± 0.001 % ) . FucB showed polydisperse profile and analysis of signals in the infrared at 1262, 1074 and 930 cm -1 and 840 assigned to S = O bonds sulfate esters , CO bond presence of 3,6- anhydrogalactose , β -D- galactose non- sulfated sulfate and the axial position of fucose C4 , respectively. FucB exhibited moderate anticoagulant activity , the polysaccharides prolonged time (aPTT ) 200 ug ( > 90s ) partial thromboplastin FucB no effect on prothrombin time (PT), which corresponds to the extrinsic pathway of coagulation was observed. This stimulation promoted fraction of about 3.6 times the synthesis of heparan sulfate (HS) by endothelial cells of the rabbit aorta ( RAEC ) in culture compared with cells not treated with FucB . This has also been shown to compete for the binding site with heparin. The rich fraction sulfated fucans exhibited strong antioxidant activity assays on total antioxidant (109.7 and 89.5 % compared with BHT and ascorbic acid standards ) , reducing power ( 71 % compared to ascorbic acid ) and ferric chelation ( 71 , comparing with 5 % ascorbic acid). The fraction of algae showed cytostatic activity on the RAEC cells revealed that the increase of the synthesis of heparan sulfate is not related to proliferation. FucB showed antiproliferative action on cell lines modified as Hela and Hep G2 by MTT assay . These results suggest that FucB Dictyota menstrualis have anticoagulant , antithrombotic , antioxidant potential as well as a possible antitumor action, promoting the stimulation of the synthesis of antithrombotic HS by endothelial cells and is useful in the prevention of thrombosis, also due to its inhibitory action on species reactive oxygen ( ROS ) in some in vitro systems , being involved in promoting a hypercoagulable state

Prevalência e fatores associados da síndrome de Osgood-Schlatter em uma amostra populacional de adolescentes brasileiros

Osgood-Schlatter (O-S) syndrome, a pathology of the musculoskeletal system, exhibits high incidence in adolescence, a phase of accelerated bone growth. Detection of physiopathological mechanisms that may cause disorders and dysfunctions in bone growth must be taken into account when planning physical activities, in order to promote normal physiological growth patterns. The aim of this epidemiological investigation was to identify and analyze the relationships between sociodemographic, anthropometric and clinical aspects and O-S. A cross-sectional design was used, with a representative sample of 956 subjects: 474 (49.6%) males and 482 (50.4%) females. Age range varied between 12 and 15 years (mean = 13.7±1.04). We used a battery of tests, previously applied in a pilot study, which met the aims of the investigation. Descriptive statistics (frequency, mean and standard deviation) were used and the odds ratio was calculated from bivariate and multivariate logistic regression (p<0.05). A prevalence of 9.8% was found (n = 94 cases): 11% males and 8.3% females. Hierarchized multivariate analysis showed a significant association between regular physical activities (OR= 1.94; CI 95%, 1.22-3.10) and shortening of the rectus femoris muscle (OR= 7.15; CI 95%, 2.86-17.86). The results may serve as a basis for therapeutic and prophylactic measures, in addition to increasing our knowledge of this syndrome in Brazilian adolescents. This investigation used a multidisciplinary approach, involving elements of anatomy, nutrition, physical education and physical therapy to elucidate the object under study related to Osgood-Schlatter syndrome

Finally, evaluates the effectiveness of the Young Agent Program from the perspective of participants

Doses e horário de aplicação do diquat no controle de Eichhornia crassipes

O aguapé (Eichhornia crassipes) é uma das mais importantes macrófitas aquáticas que colonizam reservatórios e corpos hídricos nas regiões tropicais e subtropicais do mundo, causando uma série de interferências no uso múltiplo da água e do corpo hídrico e no controle de vetores de doenças humanas. Para evitar prejuízos econômicos, sociais, estéticos e ao meio ambiente, essas plantas são controladas por vários métodos, incluindo o controle químico com o uso de herbicidas. Com o objetivo de avaliar a eficácia do herbicida diquat no controle dessa macrófita aquática, foram instalados dois ensaios em casa de vegetação. No primeiro, foram comparadas duas formulações (Reward® e Reglone®) aplicadas em dois horários (diurno e noturno) e em quatro doses (0,1, 0,2, 0,3 e 0,4 kg ha-1), num esquema fatorial 2 x 2 x 4, com seis repetições. Os resultados mostraram que a formulação Reward® foi mais eficiente no controle dessa macrófita, agindo mais rapidamente, sobretudo em menores doses, e que as aplicações realizadas no período noturno apresentavam melhor desempenho no controle em relação às realizadas no período diurno. Assim, um segundo ensaio foi realizado utilizando apenas a formulação Reward®, comparando a aplicação no período noturno e no diurno e as doses de 0,1, 0,2, 0,3 e 0,4 kg ha-1, obedecendo a um esquema fatorial 2 x 4. As plantas de aguapé foram cultivadas em caixas-d'água, e o delineamento experimental adotado foi em blocos ao acaso com quatro repetições, considerando a posição das caixas dentro da casa de vegetação. Os resultados confirmaram que o diquat é eficiente no controle do aguapé, principalmente nas doses de 0,3 e 0,4 kg ha¹ em aplicações noturnas. Doses baixas e aplicações diurnas não impediram intensas rebrotas das plantas afetadas.

Exploratory, descriptive and quantitative study with prospective data, performed in the Mobile Emergency Care Service in the metropolitan region of Natal/RN, in order to identify the knowledge of the multidisciplinary team about the rules of standard precautions and worker safety, to identify occupational hazards peculiar to the activities of this service; characterize work-related accidents (WRA) and know the procedures adopted after each WRA. The population consisted of 162 professionals and data were collected between the months of November and December 2010. As for personal and professional characteristics, of the 162 professional, 12,96% were physicians; 6,79%, nurses; 33,95%, nursing technicians, 46,29%, conductors; 74,70% were male; 43,21% were between 31 and 40 years old; 69,33% lived in Natal/RN, 50,00% had completed high school; 58,64% were married; 69,75% had children, 46,91% were between 1 and 4 years of training; 61,73% had improvement courses; 59,25% had 3 to 4 years of service; 54,32%, with 1-4 years experience in emergency; 44,44% received 1-2 minimum wages; 78,40% received insalubrity premium; 67,28% worked in Basic Support Unit (BSU); 83,95% had journey on SAMU Metropolitano of 31-40 hours per week; 52,47% had other employments. As for knowledge of rules of standard precautions, safety and occupational hazards, 99,38% knew what it was WRA; 62,96% gave incomplete answers; 74,07% knew the rules of prevent WRA; 46,67% acquired this knowledge in lectures; 53,09% knew Personal Protective Equipment (PPE); 71,60% gave incorrect answers about the importance of standard precautions; 45,06% never received an educational intervention on this issue; 89,51% said that educational interventions in the prevention of WRA are very important; 90,12% pointed out this as a very important issue in the workplace; 27,00% suggested guidance on the topic in the workplace; regarding the physical hazards, 34,57% considered noise as the most important; about chemical hazards, 78,40% chose the gases and smoke; for biological hazards, 48,77% reported contact with the blood; for mechanical hazards, 80,86% said that were transport accidents; about ergonomic risks, 40,12% say it is the tension/stress in the care of critically ill, psychiatric and aggressive patients; and there was an average of 4,5 to the feeling of safety in the workplace. Regarding the data on the WRAs occurred, 31,48% experienced at least one accident event; 72,55% did not notify it; 60,98% answered that there was no routine for notification; 56,86% were performing patient transportation; 49,02% were hurt in the Basic Support Unit/Rescue Unit (BSU/RH); 60,78% occurred during the day; 96,08% of professionals were in normal work schedule (24 hours on duty); 31,37% had contusion; 58.82% had damage to members/pelvic girdle; 43,14% had traffic accidents. About the evolution of the WRA, 62,75% did not have to take time away from work; 76,47% had no sequelae; 88,24% did not require rehabilitation; no professional had a change of occupation. And by means of univariate logistic regression, showed that the nurses and male sex were risk factors for the occurrence of WRA. We conclude that there were gaps in the knowledge of staff regarding WRA, emphasizing the need for continuing education in biosafety in the service.

Aconselhamento em HIV/AIDS: ações e reflexões dos profissionais do Centro de Testagem e Aconselhamento (CTA)

The counseling on HIV/Aids consists in a prevention strategy that contributes to increase the diagnosis of HIV and start earlier the treatment. The counseling has as pillars the emotional and educational support, risks evaluation that aim at the adoption of safe practices and the individual s responsibility for his own health. To accomplish these results, it is necessary that health workers understand counseling as a unique educational moment that stimulates the user s critical-reflection when it comes to his role as an active subject in this process. This study aimed to analyze the counseling on HIV/Aids conducted by the professionals of the Testing and Counseling Center (CTA), based on the educational perspective of Paulo Freire . This is a descriptive qualitative study with a critical reflexive design based on the principles of Action-Science. All the professionals acting as counselors in the Joao Pessoa, PB CTA, eight in total, took part in the study. Data were collected during the month of March, 2011, through non participative observation and semi-structured interviews with a critical-reflexive focus, analyzed according to the tenets of the critical-reflexive methodology, and discussed taking into consideration the Paulo Freire s pedagogy and pertinent literature. It was observed that most of the professionals expressed the work philosophy of CTA as the diagnosis and prevention of the disease, associated with the utilization and demonstration of condoms. However, upon observation of their counseling sessions, these ideas were not converted in actions. Educational themes were not covered and the condom wasn t offered at any time. The counseling actions focused on the provision of information and filling out the paper forms which are necessary for attendance. The sessions were conducted with brief dialogues and little opportunity for the users to expose or complement their thoughts and needs. The professionals mentioned as facilitating conditions for counseling, the team interaction and physical structure. The difficulties focused on the users low cognition, the large demand for attendance, aspects related to the service organization, and the counselors absences and delays. After reflecting about the actions observed in the counseling, the majority of professionals admitted the need to modify their practice in the incorporation of educational principles for the achievement of a broader prevention, and seemed to be willing to work in this perspective. In conclusion, although the counselors show ideas consistent with the purposes of CTA, these ideas are limited when it comes to the understanding of the meaning of prevention in HIV/Aids. Taking into consideration that they express a certain comprehension and act differently during the counseling, they demonstrate a lack of bond between the theories in use and the proposed ones, in accordance with the contribution of the action-science theory. The counseling, as an educative practice, doesn t materialize in the counseling itself and the orientation for reflection is not given during the attendance. These findings suggest the need to include the process of reflection in the execution of the actions of counseling, so that these practices are guided by reflexive practice, aiming at transforming the way of thinking and acting into a more educational perspective toward a more democratic and holistic assistance.

A influência da cultura organizacional na adoção de práticas de qualidade Seis Sigma: um estudo exploratório no segmento de farmácia de manipulação do Estado do Rio Grand do Norte

In recent debates about the issues of quality, the theme organizational culture and Six Sigma has appeared ever more frequently. In this context several authors suggest that the adoption of Six Sigma practices is influenced by culture. This work focuses on the relationship of organizational culture and quality to the practices of Six Sigma quality. Thus a descriptive-exploratory and correlational study of forty pharmacies of manipulation from Rio Grande do Norte was undertaken. Data collection identified features of companies and the level of use of the practices of Six Sigma quality that have been identified in the literature. For the Organizational Culture evaluation was used the Competitive Value Model (Cameron & Quinn, 1996), tested on north-American organizations and considered a high value academic and professional instrument. This model has been involved with the taximetrics created by Cameron who classifies quality culture in four levels. The results suggest that the Group and Developmental cultures are associated with higher levels of use of the practices of Six Sigma quality than the Rational and Hierarchical Cultures. Regarding the levels of the culture s quality, the highest levels were most frequently cited in Errors Prevention and Perpetual Improvement and Creativity, being the last one more positively related to the Six Sigma indicators

Free radical scavenging profile and myeloperoxidase inhibition of extracts from antidiabetic plants: Bauhinia forficata and Cissus sicyoides

There is abundant evidence that reactive oxygen species are implicated in several physiological and pathological processes. To protect biological targets from oxidative damage. antioxidants must react with radicals and other reactive species faster than biological substrates do. The aim of the present study was to determine the in vitro antioxidant activity of aqueous extracts from leaves of Bauhinia forficata Link (Fabaceae - Caesalpinioideae) and Cissus sicyoides L. (Vitaceae) (two medicinal plants used popularly in the control of diabetes mellitus), using several different assay systems, namely, 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) decolorization. superoxide anion radical (O-2 center dot-) scavenging and myeloperoxidase (MPO) activity. In the ABTS assay for total antioxidant activity, B. forficata showed IC50 8.00 +/- 0.07 mu g/mL, while C. sicyoides showed IC50 13.0 +/- 0.2 mu g/mL. However, the extract of C. sicyoides had a stronger effect on O-2 center dot- (IC50 60.0 +/- 2.3 mu p/mL) than the extract of B. forficata (IC50 90.0 +/- 4.4 mu g/mL). B. forficata also had a stronger inhibitory effect on MPO activity, as measured by guaiacol oxidation, than C. sicyoides. These results indicate that aqueous extracts of leaves of B. forficata and C. sicyoides are a potential source of natural antioxidants and may be helpful in the prevention of diabetic complications associated with oxidative stress.

Variáveis relacionadas ao processo de adesão a um programa de prevenção de quedas em idosos cadastrados na Estratégia de Saúde da Família

Introduction: Falls among older adults is a public health problem, therefore it is necessary preventive actions, however the adherence is the major problem faced by practitioners and researchers working on falls prevention programs. Objective: To evaluate the variables related to the adherence to falls prevention programs among the elderly enrolled in a Basic Health Unit (BHU). Methods: Was performed an observational cross-sectional analytical study. All elderly registered in a BHU and able to ambulate independently were invited to participate in a falls prevent program. The Elderly who Adhered to the Program (EAP) were evaluated at BHU; and the Elderly Not Adhered to the Program (ENAP) were identified and assessed at home. The assessment for both groups was performed using an evaluation form containing personal data, measures and clinical scales to assess cognitive status, balance, mobility, fear of falling, handgrip strength. Data were analyzed with SPSS 20.0. In addition to this assessment, the ENAP underwent a semi structured interview, in which we used the qualitative approach based on the figure of the Collective Subject Discourse. Results: The study included 222 elderly, 111 EAP and 111ENAP, most aged between 70 and 79 years (48.2%), female (68.5%), married (52.3%) and illiterate (47.7%). Consolidated as protective factors for adherence, worst rates of physical activity (p = 0.001), balance (p = 0.010) and cognition (p = 0.007). The interview of ENAP identified two themes: "Local implementation of programs for the prevention of falls" and "Relationship between BHU and the elderly health care," and found that the elderly who did not adhere were unable to displace and did not mention that primary care programs are related to health care in elderly. Conclusions: Elderly who do not adhere to the program differ from elderly who adhere as worst indices of cognition, balance and physical activity which implies greater risk of falling; and they were unable to participate in falls prevention program and by to be caregiver and showed displacement difficult
