Life and Death: The Religious, Philosophical and Moral Dilemmas in Medicine

Religious beliefs often play a major role in the decisions that are made in the home and the hospital concerning issues at the beginning and end of life. Only recently, however, due to rapidly advancing medical technology, have religious, moral, and philosophical beliefs taken such a controversial role. One of the major questions that has arisen from these various controversies is whether or not we have the right to posses control over the biological functions of our bodies. The answer is a difficult one, and it may be one that cannot be answered, but the attempt at an answer is what is at the heart of medical ethics.

A relação entre desenvolvimento cognitivo e estimulação precoce em alunos da 4. serie do 1. grau

O presente estudo teve por objetivo uma verificação experimental da influência da estimulação precoce no desenvolvimento cognitivo. A ideias deste trabalho surgiu da importância que ora se atribui ao problema de um melhor aproveitamento do homem em suas potencialidades para a construção de uma humanidade melhor. Tal possibilidade reflete-se primordialmente no âmago do processo educativo, e em particular a escola. Fundamentou-se teoricamente em Gerome Bruner, tendo por central 2 de suas proposições: Qualquer assunto pode ser ensinado com eficiência, de forma honesta, a qualquer criança em qualquer estágio de desenvolvimento; É objetivo primordial da educação atingir a imaturidade, levando o homem a ser mais produtivo, mais ajustado à sua cultura, desenvolvendo suas potencialidades ou indo além delas para criar mais. Buscando um maior embasamento, a autora se valeu de estudos teóricos e experimentais de Piaget, Montessori, Okón, Poppovic, Oslon, Austin & Postethwaite, e outros, além de algumas pesquisas realizadas por autores ou instituições brasileiras. O estudo dirigiu-se, especificamente, a alunos da 4º série do 1º grau, para medir competência pedagógica e conhecer dados referentes à escolarização inicial. Os resultados obtidos confirmaram a hipótese fundamental de que quanto mais precocemente a criança for estimula da, maior será sua competência pedagógica posterior, o que se pressupõe ser decorrente da aceleração de seu desenvolvimento cognitivo. Entretanto, face às delimitações criadas e às limitações sofridas, a autora sugere a realização de pesquisas ulteriores sobre o tópico, a fim de que se possa, diante de dados experimentais cada vez mais consistentes e de maior amplitude, propor, de forma mais enfática, uma aplicação psicopedagógica adaptada à realidade social e tecnológica de nossa era.

Influência das áreas verdes no microclima local: um estudo do conjunto habitacional Ponta Negra, Natal/RN

Owing to na intense process of urban development, urban uneasiness and discomfort in the daily life of populations have nowadays, especially in the big cities, become increasingly ordinary issues. Population density, degeneration of central areas and pollution are some of the environmental stressors the urban man is subjected to. The existence of open areas in the urban network contributes to a better movement of the air and transforms salubrity conditions. Yet, it has been noticed that parks and squares are disappearing from the heart of the city districts. In their place there are either unused plots of land where garbage has been dumped or nearly all-paved squares with meager or no vegetation at all. Such areas, when handled properly, play an important role in the city because in addition to being zones for rendering a mild climate they perform social, cultural and hygienic functions. Aiming at demonstrating that proper handling of green areas can favorably influence the local microclimate, we have attempted to develop analysis from the point of view of bioclimatizing attributes of urban form and their relationship to the local microclimate found in the eight open areas located in the Ponta Negra Housing Complex in the city of Natal/RN

Perdas fermentativas e composição bromatológica da entrecasca de palmito pupunha ensilada com aditivos químicos

Objetivou-se avaliar o efeito da inclusão de aditivos químicos na ensilagem de resíduos (entrecasca) da produção de palmito pupunha (Bactris gasipaes, Kunth). Utilizaram-se silos experimentais (baldes de 20 litros) providos de aparatos para determinação gravimétrica de perdas por gases e efluentes. Os tratamentos aplicados foram: controle (sem aditivos); ureia (1% da MV) e cal virgem (1% da MV). Decorridos 70 dias de armazenagem, os silos foram pesados, abertos e amostrados. As perdas por efluentes e gases aumentaram com a aplicação de cal virgem na ensilagem. As perdas totais de MS foram de 15,1; 14,4 e 26,6% nas silagens controle, ureia e cal, respectivamente. em todas as silagens, houve redução no teor de FDN e elevação da fração FDA, o que indica desaparecimento da fração hemicelulose. A relação cálcio:fósforo aumentou substancialmente com a adição de cal virgem, de 4,1:1 na silagem controle para 15,6:1 na silagem com cal. O resíduo da extração do palmito pupunha pode ser classificado como alimento de média qualidade e alto teor de umidade. Os aditivos aplicados na ensilagem não são efetivos em reduzir as perdas fermentativas no processo de conservação.

Michel Foucault e a dominação: contribuições para a sociologia

In this master s thesis I intend to carry out an interpretation of Michel Foucault s thought that points out the relations and theoretical, conceptual and thematic consequences with sociology in his work and theoretical propositions. For my argumentation and analysis I take as a base a specific part of his thought: the problem of domination in modern societies in the genealogic texts in the decade of 1970. It s about to identify how Foucault does his analysis of the relations of domination and the use of the power with the objective to suggest and point out his contribution to sociological analysis of domination. I will discuss the foucaultian program of the study of domination from four units of analysis: person constitution, knowledge, power and truth. The structure and division of the chapters will follow the specific and detailed study of each of those units of analysis, prioritizing their theoretical sense and consequences to the sociology. Thus, in the first chapter, I will highlight a little more the relations of affinity and the convergences between Foucault and the sociology in a way to offer more elements to justify the general objectives that this work intends to achieve. In the second chapter, I will analyze the subject of domination in Foucault s thought, discussing his basic presuppositions and its intrinsic relation with the heart of the foucaultian philosophical project, the person constitution. In turn, in the third and fourth chapter, I will discuss the interdependence between knowledge and power as an essential and opaque dimension of the ways of modern domination. In the fifth chapter, I will analyze the relation between domination and the truth discourse production

Influência da temperatura e da luminosidade no desenvolvimento de Guignardia citricarpa, agente causal da mancha preta dos frutos cítricos

O presente trabalho teve como objetivo avaliar sob condições de laboratório, o efeito de temperatura (15, 18, 20, 21, 24, 25, 27, 30, 33 e 35 ± 1 ºC) nas condições escuro, luz contínua e fotoperíodo 12/12 h, na produção de pseudotécios de isolados de Guignardia citricarpa, provenientes de regiões cítricolas dos Estados de São Paulo e Rio de Janeiro. Discos de folhas de limoeiro 'Cravo' (Citrus limonia), de 12 mm de diâmetro, foram autoclavados e depositadas (parte abaxial) na superfície do meio de cultura constituído por ágar-água 2%. Foram colocados quatro discos de folhas por placa onde, de forma conjunta e intercalar aos mesmos, depositaram-se dois discos obtidos de colônias de Phyllosticta citricarpa, com 21 dias de incubação. Foi, também, estudado o efeito da temperatura e do tempo de incubação (2, 8 e 16 h) na germinação dos ascósporos. Após 21 dias de incubação, a ótima temperatura ajustada pela função beta generalizada, para produção de pseudotécios deu-se a 26 e 22,5 a 27,5 °C, sob condição de escuro e de luz, respectivamente. Observou-se também produção de pseudotécios a 27 ºC em fotoperíodo 12/12 h. em estudo complementar foi verificado que, aos 19 dias, a 27 ºC, cerca de 90% dos pseudotécios haviam alcançado a maturidade, com abundante produção de ascósporos. A maior porcentagem de ascósporos germinados foi constatada na temperatura de 24 ºC, após 16 h de incubação. Dentre as vantagens alcançadas, incluem-se a possibilidade (i) da produção massal de ascósporos em curto período de tempo, e (ii) da padronização do inóculo, tanto qualitativa, quanto quantitativa.

Para uma andragogia do esporte:discutindo as diretrizes e a formação profissional para a Educação Física de Jovens e Adultos

For the development of this research the following general objective has been formulated, indicator of the process of inquiry: To discuss the relation between the attitudinal and the sportive contents presented in the proposal of Curricular Lines for the Physical Education of Young and Adults in Brazil. According to the corporeity and the ludicity, questioning the formation of the professional of Physical Education and delineating the perspective for a sport andragogy that values the Being and the Life. From this general objective, the following objectives, which had given greater specificity to the investigative process, were defined: 1. To create the theoretical context from the corporeity/ludicity axis, articulating transversally sportive knowledge, aiming to contribute for a sport Andragogy; 2. To analyze the objectives proposed for the Physical Education of Young and Adults according to an elaborated theoretical reference and to the testimonies of the egresses of 2005 of the Physical Education course of the UFRN. 3. To interpret the relation between attitudinal and educative content from the academic reality lived by the egresses of the Physical Education course of the UFRN. 4. To understand the most urgent necessities of sustained formation of the egresses of 2005 for satisfactory performance with the Physical Education of Young and Adults. 5. To propose perspectives for the construction of a sport Andragogy from the corporeity/ludicity axis. In attendance to the nature of this research and as form of guiding ourselves in this epistemological adventure, the following ones had been basically and theoretically estimated. 1. Corporeity is a radiant focus, prime and main of educational criteria; 2. The task of the education must be carried through with men and not for men; 3. Man must only play with the beauty and with the beauty he only must play. ; 4. The sportive education must be based on esthetic and fair play. The adopted research approach is of a qualitative nature, using the interview procedure with a group consisting of twelve egresses of the Physical Education Course of the UFRN of the year of 2005.2 After the discussion of the results on the attitudinal objectives and content for the Physical Education for Adults and Young, the study shows nine themes presented by the investigated group as priorities for their sustained formation, aiming at the performance of the professional of Physical Education with the EJA: inclusive experiences; leisure and quality of life; relationships; body and personal care; social values; self esteem; sportive phenomenon; EJA training; attitudinal contents. As a contribution to the construction of knowledge for a Andragogy of Sports, the study presents a metaphorical structure called Galaxy of Knowledge righteous Glamor of integrating nine elements inspired by the Ode to the Sport of Pierre de Coubertin: life, beauty, justice, daring, honesty, joy; Fertility; progress; peace. At the heart of the structure of knowledge is righteous install a system that articulates five principles ludopoiético epistemological function of connecting with the righteous knowledge of the sport that must integrate the content attitudinal proposed for Fitness for Youth and Adults in order to facilitate the realization of their objectives proposed for this method of teaching

Espaços transversais em educação matemática :uma contribuição para a formação de professores na perspectiva etnomatemática

This PH.D. thesis is an attempt to show the beginning, evolution and unfolding of the making of a pedagogical work proposal based on culturally-built knowings in the heart of a traditional community, having as one of its starting points the knowings and doings experienced by dish-making women from Maruanum living in the city of Macapá, State of Amapá, Brazil. This proposal is strongly associated with the need we have to think about the nature of (ethnological)-mathematical knowledge generated by particular communities and about the way such knowledge can be discussed, worked out, and validated in learning environments, regardless of the level of instruction and the constraints imposed by government programs and educational institutions. Among its theoretical foundations are studies on instrumental activities that are typical of the Maruanum ceramics and investigative studies from the point of view of ethnomathematics. Methodological development took place with the application of activities, where traditional and instrumental knowledge observed in the production of ceramics had been adapted for and brought into the school environment , participative observation, as well as data collecting and organization techniques, such as interviews, statements, and audio an visual recordings. Analysis of the data collected focused on the relationship between the data-generating potential and the purpose of this study. Our aim is to make and estimate of the potential contributions from local situations and/or problems it would possibly bring to the formative learning of people involved in the educational processes of these communities, with a view to a spatial and temporal transformation of reality

Uma conversa na escola: o diálogo e a mídia

The dialogue represents an essential condition for the complete realization of the Communication. In Paulo Freire we find a concept of dialogue which expresses itself, fundamentally, in two dimension: on one hand, in the confluence of subjectivities; on the other, in action. Dialogue would not be, therefore, a thinking for , but a thinking with . On the other hand, the media, here understood as synonym of technical media of information and expression is spread all over society as synonym of communication media. In this direction, this paper intends to check if the media allows the dialogue, in the heart of the Freirean concept of communication. We start from the premise that it is not possible to come to an answer if we continue to accept the theoretical approach which polarizes the process of communication between emitter and receptor. By using elements of the ethnomethodology such as the analysis of the conversation and the reflexivity, we dived in the school everyday life of educators and students of an elementary level public school in the city of Natal, capital of Rio Grande do Norte, in order to, through some experiences with the media, corroborate Paulo Freire's ideas, stating the mediation made by the world and seeking a bias for the use of the media to enable a more dialogic education

Heat or cold chronic stress affects organ weights and Hsp70 levels in chicken embryos

This study was carried out with the objective of evaluating the effect of heat (38.8 degreesC) or cold (35.8 degreesC) stress on chicken embryo development and tissues Hsp70 levels, after the 13th day of incubation. Embryo weight (percent egg weight), organ weight (percent embryo weight) and Hsp70 levels (ng Hsp70 mug(-1) total protein) in different tissues (liver, breast muscle, heart, lungs, brain and kidney) were studied at the end of incubation. Cold stress induced a lower embryo weight and lower kidney and lungs weights, whereas heart and liver were lighter in heat-stressed embryos. An interaction between temperature and age was obtained only for Hsp70 levels in kidney and heart. Cold-stressed embryos showed higher Hsp70 levels in the brain, lungs and liver; a decrease in brain and breast muscle Hsp70 levels was seen from the 19th to 20th days in control embryos. Hsp70 levels increased with age in kidneys of control embryos and in heart of heat- and cold-stressed embryos. In conclusion, this study showed that chicken embryo organ weights are affected by incubation temperature, and that Hsp70 expression is tissue dependent (higher levels being seen in the brain) being cold-stress more effective in increasing Hsp70 levels in most studied tissues.

Descrição anátomo-topográfica do coração da paca (Agouti paca)

Background: The domestic animals heart is a conical hollow viscera, surrounded by pericardium, laterally compressed, accompanying the thorax shape. Atriums constituted the heart basis and their auricles partially bound the initial portion of the aorta and pulmonary trunk. In mammals, heart is kept suspended in the thoracic cavity and the pericardic sac is fixed dorsally by great veins and arteries roots, and ventrally fixed to the sternum, although its fixation to the diaphragm varies among species. This paper aimed to describe morphological aspects of the heart of the paca, the second biggest Brazilian rodent.Materials, Methods & Results: There were used 12 hearts of adult pacas for this study, obtained from the UNESP, Jaboticabal, SP, which died due fights or anesthesia during bandages or radiograph exams. The thoracic aorta was filled with colored latex and the animal was set in a 10% formaldehyde solution for at least 72 hours. The thoracic cavity was dissected and hearts individualized and measured with a paquimeter, lateromedially, craniocaudally and dorsoventrally. The paca heart is placed between the first and fifth intercostal space (ICS), in a craniocaudal oblique position; its basis is craniodorsally positioned, on the middle third between the first and second ICS and its apex is located near the sternodiaphragmatic joint, on the fifth ICS, tilted to the left antimere. The heart is surrounded by pericardium, which from ventrocaudally is originated the sternopericardic ligament, that continues as phrenopericardic ligament. At the heart basis, the rising of the pulmonary trunk was observed and the conus arteriosus formed a typical projection. The aorta also rised from the heart basis and its arch, which was caudally curved, crossed dorsally the pulmonary trunk; the right cranial and caudal cava veins drained to the right atrium. There is a left cranial cava vein, which surrounded the left atrium and joined the right caudal cava vein on the right atrium. The azygos vein joins the right cranial cava vein and four pulmonary veins drained to the left atrium. At palpation, a hard structure on the rising of the aorta was observed, similarly to a cartilaginous tissue, which would be part of the cardiac skeleton. The left and right coronary arteries were observed in all hearts.Discussion: The paca heart is anatomica and topographically similar to those of domestic mammals, differing from them for being placed one intercostal space more cranial and due to the presence of two cranial cava veins, the left and the right ones, besides the presence of the caudal cava vein. This vascular description is similar to that of small rodents, as rats and mice. In paca heart, the sinus venous, the terminal crest, the oval fossa, the atrioventricular valvae, the papillary muscles and tendinous cords, besides smooth atriums and auricles covered by pectinate muscles, were observed. The sternopericardic ligament, which is dorsally elongated as phrenopericardic ligament, is similar to the one present in humans, pigs, castors, and different from the one observed in carnivorous, that presents the phrenopericardic ligament and from the one of horses and ruminants, which present the sternopericardic ligament.

Emergência e crescimento inicial de plântulas de Archontophoenix cunninghamiana H. Wendl. & Drude provenientes de sementes de diferentes plantas matrizes

A diversidade genética é um fator fundamental nos programas de melhoramento e seleção de plantas, dessa forma, o objetivo no trabalho foi avaliar genótipos de Archontophoenix cunninghamiana quanto à emergência e crescimento inicial das plântulas, no sentido de orientar a seleção de plantas matrizes. Os frutos maduros foram colhidos em dez plantas matrizes em Monte Alegre do Sul - SP, nos quais se avaliaram o peso e as dimensões e, nas sementes, também o peso e as dimensões, além do teor de água, emergência, índice de velocidade de emergência, diâmetro e comprimento da parte aérea e massa seca de plântulas. O delineamento utilizado foi o inteiramente casualizado e a comparação entre médias foi realizada pelo teste de Tukey (P<0,05). Entre as sementes das matrizes, há diferenças nas características físicas e fisiológicas, o que possibilita a identificação e seleção de matrizes produtoras de sementes de qualidade superior.

Tamanho e secagem de sementes de palmeira Jussara sobre a germinação e o vigor

With the objective to determine the influence of the dehydration and of the size and/or weight on germination percentage and the vigor of jussara palm seeds (Euterpe edulis Mart.), 10 individuals' ripe fruits, picked in the Experimental Station of Ubatuba (IAC) they were classified by size in 5 sieves of circular sieve: 26/64" (10,31mm), 28/64" (11,11mm), 30/64" (11,90mm), 32/64" (12,69mm) and 34/64" (13,49mm). It was determined, the medium weight of the classified seeds. The quality of the seeds was evaluated through the following parameters: water content of the seeds; germination and vigor (first germination counting). It was evaluated the drying speed of different seed sizes for 48 hours, in dry chamber. The sizes of 28/64", 30/64" and 32/64" represented 98,7% of the total weight of the harvested seeds and showed similar drying speed, percentage of germination and vigor. With the increase of the drying period, the smaller seeds (28/64") had their germination less affected them the intermediate (30/64") and bigger sized seeds (32/64").
