Made available in DSpace on 2018-08-01T23:26:07Z (GMT). No. of bitstreams: 1 tese_4200_Dissertação Priscilla Coppo.pdf: 1792164 bytes, checksum: a5582e0f738e32fbe27c3261e5994d2d (MD5) Previous issue date: 2010-04-16 / Os estudos clínicos de dentes desvitalizados e restaurados com pinos mostram resultados semelhantes no que diz respeito ao percentual de falhas ou insucessos, apesar de tantas variações técnicas, metodológicas e operatórias entre eles. Os insucessos são maiores quando se tratam de elementos dentais coronariamente destruídos ou comprometidos periapicalmente. Com o objetivo de identificar o efeito das variações clínicas que influenciam na longevidade do tratamento e a prevalência de descimentação de pinos, cárie marginal, fraturas radiculares e de lesões periapicais, foi realizada uma análise retrospectiva do desempenho clínico de dentes restaurados com pino de fibra de carbono. Foram avaliados 139 dentes em 75 pacientes, três anos após a data de cimentação dos pinos. Os dentes foram submetidos a tratamentos endodônticos, incluindo preparos dos condutos para pino, e tratamentos restauradores, realizados pelo mesmo endodontista e protesista, respectivamente, segundo protocolos padronizados. Através de exame clínico, radiográfico, fotográfico, laudos endodônticos e informações obtidas de prontuários, os dentes foram classificados de acordo com: grupos dentais, modalidade de tratamento endodôntico recebida, intervalo decorrido entre a última sessão endodôntica e a cimentação do pino, morfologia do pino, quantidade de remanescente dentinário coronário após preparo protético e sistema da coroa protética utilizado. Não foram constatadas descimentações de pinos, fraturas radiculares, ou cáries, e a classificação foi favorável para 99,3% (138 dentes) dos tratamentos endodônticos realizados. De acordo com os parâmetros analisados, os resultados desse estudo revelaram que as variações clínicas identificadas, consideradas desfavoráveis, não foram fatores determinantes para o insucesso, partindo-se do conjunto de procedimentos e materiais utilizados para o tratamento dos dentes desses pacientes. / Clinical studies of devitalized teeth restored with posts show similar outcomes with regard to the percentage of faults or failures, despite many technical variations, methodological and operative between them. The failures are greater when dealing with teeth coronally destroyed or periapically compromised. The aim of this study was identify the effect of clinical variants that influence the longevity of treatment and prevalence of dislodgment of post, marginal caries, root fracture and periapical lesions was performed a retrospective analysis of clinical performance of teeth restored with carbon fiber post. 139 teeth were evaluated in 75 patients, three years after the date of cementing the posts. The teeth were root canal treatments, including preparations of the conduits to posts, and restorative treatments, performed by the same endodontist and prosthetics, respectively, according to standardized protocols. Through clinical, radiographic, photographic, endodontic reports and information obtained from medical records, the teeth were classified according to: tooth groups, type of endodontic treatment received, time span between the last endodontic session and bonded post, morphology of the post, amount of remaining dentin after crown preparation and prosthetic crown system used. There were no dislodgment of post, root fractures, or caries, and the rank was favorably for 99.3% (138 teeth) of endodontic treatment. According to these parameters, the outcomes of this study revealed that the clinical variations identified, that are considered unfavourable, were not determining for the failure, starting from the set of procedures and materials used for dental treatment of these patients.

Influência da presença e do tipo de retentor intrarradicular no comportamento em fadiga de incisivos centrais restaurados com coroas totais /

Andrade, Guilherme Schmitt de. January 2019 (has links)
Orientador: Guilherme de Siqueira Ferreira Anzaloni Saavedra / Coorientador: Lilian Costa Anami / Banca: Carlos Eduardo Francci / Banca: Clovis Pagani / Resumo: Este estudo avalia a influência da presença e tipo de pinos e núcleos na sobrevivência à fadiga de incisivos centrais restaurados com coroas totais. As coroas de 69 incisivos bovinos foram cortadas e as raízes tratadas endodonticamente. As raízes foram distribuídas aleatoriamente em três grupos (n = 23): núcleo de resina composta (NRC), núcleo de resina composta retido por pino de fibra de vidro (PFV) e núcleo metálico fundido (NMF). Todos receberam preparo de coroa total com férula de 2 mm, e então, uma coroa de cerâmica reforçada com leucita foi adesivamente cimentada. Três amostras de cada grupo foram testadas para determinação da carga máxima até a falha. As amostras restantes foram carregadas pelo teste acelerado de fadiga stepwise stress até a fratura ou suspensão após o término de 1,5 x 106 ciclos. A carga e o degrau em que cada espécime falhou foram analisadas pela estatística de Kaplan-Meier e Mantel-Cox (Log Rank test), seguidas por comparação múltipla aos pares, com nível de significância de 5%. O modo de falha foi analisado com estéreomicrocópio. Não houve diferença estatística entre os tratamentos quanto à carga (Mantel-Cox Log-Rank test for trend, X2=0,015, df=1, p=0,901), nem para o número de ciclos (Mantel-Cox Log-Rank test for trend, X2 =3,171, df=1, p=0,995). O modo de falha predominante foi a trinca da coroa. Fratura obliqua da raiz só foi observado nos grupos retidos por pinos.

The crowns of 69 bovine incisors were cut and endodontically treated. The roots were randomly assigned into three groups (n=23): composite resin build-up (NRC), glass fiber post-retained-composite build-up (PFV) and cast post-and-core (NMF). All specimens received crown preparation with a 2 mm ferrule, and then a leucite-reinforced ceramic crown was adhesively cemented. Three samples from each group were tested for the determination of the maximum load to failure. The remaining samples were loaded by the accelerated fatigue stepwise stress test until fracture or suspension after the end of 1.5 x 106 cycles. The load and the step on which each specimen failed were analyzed by the Kaplan-Meier and Mantel-Cox (Log Rank test) statistics, followed by multiple paired comparisons, with a significance level of 5%. The failure mode was analyzed with stereomicroscope. There was no statistically significant difference between the treatments (Mantel-Cox Log-Rank test for trend, X2=0.015, df=1, p=0.901), nor for the number of cycles (Mantel-Cox Log-Rank test for trend, X2=3.171, df=1, p=0.995). The predominant failure mode was the crown crack. Oblique root fracture was observed only in groups retained by posts. The presence and type of post system did not influence the fatigue survival of the endodontically treated incisors with a 2 mm ferrule. Non-restorable fractures only occurred on teeth restored with posts...(Complete abstract click electronic access below) / Mestre

Nessa organização, inserem-se diferentes tipos de eventos de moda que necessitam acompanhar as mudanças impostas pelo sistema, indo ao encontro das expectativas das pessoas. Este estudo delimita-se em analisar as relações de experiência e emoções estabelecidas entre indivíduos e exposições de moda adulta feminina. A metodologia utilizada no estudo é constituída por revisão bibliográfica e pesquisa de campo exploratória, contemplada por meio do desenvolvimento e da análise de duas exposições de moda, intituladas como Experimentos I e II. Teve-se como premissa de estudo que as relações firmadas entre o público espectador e as exposições de moda ocorrem através de diferentes formas de interatividade, sendo a estimulação dos sentidos vitais uma importante ferramenta viabilizadora de experiência. Os resultados apontam que a interatividade e o ineditismo são fatores apreciados pelos indivíduos durante exposições de moda e a estimulação dos sentidos vitais ocorre, de modo mais evidente, indiretamente. Tais constatações motivaram o desenvolvimento de uma proposta imagética e teórica que sintetiza os comportamentos analisados entre indivíduo e contextos de eventos que podem ser verificados nas considerações finais. / The fashion system is organized in contemporary society through the assumption of constant renewal due to its ephemeral nature. Into this organization several types of fashion events are inserted, that need to follow the changes imposed by the system, going against people’s expectations. This study limits itself to analyze the relations of emotion and experience established between individuals and adult female fashion exhibitions. The methodology of the study consists of literature review and exploratory field research, viewed through the development and analysis of two fashion exhibitions, titled as Experiments I and II. We had as this study’s premise that relations signed between the viewing public of exhibitions and fashion take place through different forms of interactivity, being the stimulation of vital senses an important experience enabler tool. The results show that the interactivity and originality are factors valued by individuals during fashion exhibitions, and the stimulation of the vital senses occurs, most evidently, in an indirect way. These findings motivated the development of a theoretical proposal and imagery that synthesize the analyzed behaviors between individuals and contexts of events that can be verified in the final considerations.

Sjukvårdspersonals upplevelser av att använda bedömningsinstrument på barn (Pediatric Early Warning Score)

Karanikas, Birgitta, Jernberg, Birgitta January 2013 (has links)
Abstract The aim of the studie was to investigate if the Pediatric Early Warning Score system, PEWS, is an useful instrument on a children's inpatient ward, regarding the detecting of deterioration in children's vital signs. For this, a quantitative descriptive design with qualitative elements was used. Method: Study specific questionnaires were distributed to 86 persons (helpnurses, nurses and doctors). Of these, 36 answered and sent back the surveys. Results: Of 36 responses 25 felt experienced a faster detection of deterioration of vital signs in the child. Many felt that they had faster response from the physician on call by providing an assessment figure of the child's condition. Conclusion: Most of the persons experienced that the use of the assessment intrument PEWS detected a deterioration of the child´s vital signs earlier than before using the instrument. Staff experienced greater security in their work when they had a tool to help and they also experienced an earlier response from physicians. / SAMMANFATTNING   Syftet med studien var att undersöka om bedömningsinstrumentet Pediatric Early Warning Score, PEWS, är till användning och vägledning på barnavdelning med avseende att upptäcka försämring av barns vitalparametrar. För detta användes en beskrivande kvantitativ design med kvalitativa inslag. Metod: Ett studiespecifikt enkätformulär gick ut till 86 personer (undersköterskor, sjuksköterskor och läkare på två pediatriska vårdavdelningar). Av dessa besvarades 36 enkäter. Resultat: Av 36 svarande ansåg 25 att man snabbare upptäckte försämring av vitalparametrarna hos barnet. Många ansåg att de fick snabbare gensvar från jourläkare genom att uppge en bedömningssiffra över barnets hälsotillstånd. Slutsats: Med hjälp av bedömningsinstrumentet PEWS upplevde personalen att en upptäckt av försämring av barnets vitalparametrar gjordes tidigare, samt att gensvar från jourläkare erhölls snabbare. Personalen upplevde en ökad trygghet i sitt arbete då man hade ett arbetsredskap till hjälp.

Comparación de la eficacia del aprendizaje basado en casos/problema frente al método tradicional de lección magistral para la enseñanza de la Anestesiologia en pregrado, postgrado y formación Médica Continuada

Carrero Cardenal, Enrique Jesús 10 September 2009 (has links)
ANTECEDENTES: La metodología docente es un campo de investigación poco explorado. En Medicina, es difícil diseñar métodos de evaluación capaces de medir y comparar los resultados de la enseñanza. En la Anestesiología en particular, no existe consenso sobre cuál es el método de enseñanza más eficaz. La clase magistral sigue siendo el método de enseñanza tradicional más extendido. El método aprendizaje basado en la discusión de casos/problema (ABDCP) es una modalidad de aprendizaje basado en problemas que puede superar sus limitaciones y se adapta bien a los programas de formación. Los métodos de evaluación han de definir con claridad las competencias que están midiendo, el nivel de resultados y el nivel de evaluación. La investigación docente en Anestesiología ha de basarse en criterios objetivos. OBJETIVO: Comparar la eficacia del ABDCP con la clase magistral en la enseñanza de Anestesiología en los tres programas de formación: Pregrado, Postgrado y Formación Médica Continuada.MATERIAL Y MÉTODOS: Tres artículos de la misma línea de investigación; cada artículo enmarcado en un nivel de formación. Diseño adaptado al programa docente. Hoja de instrucciones y consentimiento informado. Participación voluntaria, anónima y no puntuable. Tres estudios controlados, prospectivos y randomizados según el método docente: clase magistral (grupo clase magistral) o ABDCP (grupo caso/problema). Aprobación por Comisiones de Investigación y Docencia. Cálculo del tamaño muestral: riesgo &#61537;: 0,05, riesgo &#61538;: 0,2. La población de los estudios incluyó, 68 estudiantes de medicina, Pregrado, UB (artículo 1), 54 residentes de Anestesiología de primer año Postgrado, SCARTD (artículo 2) y 52 alumnos del curso 5 de Formación Continuada FEEA (artículo 3). Enseñanza: sesión única, objetivos docentes y tiempo de clase igual en los dos grupos. Participaron dos profesores expertos en el tema y en la metodología docente. Clase magistral: formato original; ABDCP: sin casos por adelantado. Los estudios incluyeron una evaluación antes de la enseñanza (pre) y otra inmediatamente después (post). Las evaluaciones se basaron en situaciones clínicas hipotéticas que cumplían los objetivos docentes. Se realizó una prueba piloto previa a cada estudio. Las variables de las evaluaciones fueron diferentes campos del conocimiento que medían habilidades cognitivas e integrativas. Cada campo incluía un número determinado de ítems sobre los que se contabilizó el número total de respuestas correctas. Las evaluaciones fueron puntuadas por dos evaluadores diferentes a los dos profesores, ciegos a la asignación de grupos. Analizamos el índice de concordancia kappa. Consideramos relevante que el porcentaje de alumnos que mejoraron sus puntuaciones en cada campo fuese superior al 50%. Definimos la significación estadística como P < 0,05.RESULTADOS: El índice kappa fue > 0.8 para todas las evaluaciones. Antes de la enseñanza, no encontramos diferencias significativas entre los grupos para sus características demográficas ni en las evaluaciones pre, excepto para uno de los campos en el artículo 2. Ambos métodos mejoraron de forma similar los campos del conocimiento analizados. La mayoría de los estudiantes no obtuvieron la máxima puntuación para ninguna de las evaluaciones post. No encontramos diferencias significativas entre los grupos después de la enseñanza en ninguno de los campos analizados. El análisis de los incrementos absolutos de puntuación y la ganancia de puntuación no mostró diferencias significativas entre los grupos. Tampoco encontramos diferencias entre los grupos en el porcentaje de estudiantes que mejoraron sus puntuaciones post. A mayor nivel de formación, disminuyó el número de campos y el porcentaje de alumnos que mejoraban su puntuación en ambos grupos.CONCLUSIONES: La eficacia de la clase magistral y el ABDCP fue similar para las habilidades cognitivas e integrativas analizadas. Las limitaciones del estudio impiden generalizar nuestros resultados. El diseño y metodología aplicados permitío una valoración objetiva de la enseñanza.

Wassily kandinsky y la evolución de la forma: fundamentos teóricos para presenciar el espacio y el tiempo

Maltas i Mercader, Antoni 09 November 2009 (has links)
¿Es posible abordar cuestiones pictóricas en Kandinsky en función del tiempo más bien que del espacio?, ¿cómo puede el tiempo ser la medida de un trabajo de Kandinsky cuando lo pictórico se manifiesta básicamente por una extensión sobre un soporte material?En Cours du Bauhaus, una recopilación de anotaciones de Kandinsky, aparecen términos como origen, transformación, adaptación, movimiento, evolución, etc. Son conceptos extraídos de estudios y experimentos vinculados con las ciencias de la naturaleza. Kandinsky traslada los resultados de la experimentación sobre las transformaciones que se dan en los organismos vivos al trabajo pictórico. Manuscritos de Kandinsky publicados recientemente confirman su interés por las teorías evolucionistas. Kandinsky conocía los principios postulados por Darwin. Si bien parece que acepta la idea darwiniana de un antepasado común, en un texto de Punkt und Linie afirmará que las leyes que rigen las semejanzas formales en los seres vivos no son directamente aplicables al trabajo artístico.En una anotación de Cours du Bauhaus destaca la importancia del vitalismo, una doctrina que sostiene que los fenómenos vitales poseen un carácter singular y específico que les aleja de toda concepción que los reduce a fenómenos mecánicos o físico-químicos. La referencia bibliográfica de este apunte es Die Kultur der Gegenwart, la misma publicación de la que extrae algunos de los esquemas que aparecen en Punkt und Linie. Es la única vez que aparece el nombre de Henri Bergson en un texto de Kandinsky.Kandinsky elabora un sistema de representación a partir de unos escritos teóricos que ven en el cambio la realidad más profunda de las cosas, una gramática formal en la que la evolución de la forma sustituya a cada una de las formas realizadas una a continuación de otra, y en la que en el movimiento haya más que en las sucesivas posiciones de un móvil. La teoría darwiniana de la selección natural intentaba explicar la adaptación de las especies al medio. Kandinsky definirá unas leyes que regulen la adaptación de los elementos formales entre sí. Una forma es el resultado de una mutua adaptación entre lo material y lo psicológico. Kandinsky introduce en algunos de sus trabajos un artificio que suscita movimiento: el péndulo, un aparato que se adapta perfectamente a los mecanismos que nuestro intelecto usa para reproducir el movimiento. El péndulo se adecua al yo interior del observador, lugar donde se da el tiempo verdadero, nunca fuera de éste. El péndulo es, en el sistema kandinskyano, el elemento formal paradigmático del movimiento.La gramática kandinskyana no se basa en unas leyes que requieran un conocimiento previo. Los contornos de los elementos formales son lo suficientemente permeables para que nuestro yo inserte su acción y los modifique según sus necesidades. Kandinsky no pretende mostrarnos unos acontecimientos, sino que asistamos a ellos; no debemos observar algo que acontece delante nuestro, porque lo que acontece ante nosotros somos nosotros mismos. Presenciamos un balanceo entre dos extremos aparentemente opuestos; a continuación presenciamos el cambio, nos instalamos en el movimiento. Es el momento de la adaptación recíproca entre nuestro tiempo y el de la composición. El lenguaje kandinskyano, basado en la acción, se conjuga en presente.Concluiremos que dibujo de Kandinsky no es la representación de algo estable, sino una sucesión de vistas: el resultado de un esfuerzo para situarse en el devenir. Aunque estamos sobre un soporte material, las formas todavía no han perdido su contacto con el movimiento. Los elementos formales que percibimos se dan en el devenir. Son dibujos que se hunden más en una dimensión temporal que espacial: duran porque los hacemos durar en nuestra duración. Concluiremos, también, que Essai sur les données immédiates de la conscience, "Introduction à la métaphysique" y L'Évolution créatrice, escritos de Bergson, son fuentes primarias que configuran el trabajo de Kandinsky. / It is possible to raise pictorial questions in Kandinsky depending on the time rather than the space? How can time be the measure of a Kandinsky work when the pictorial becomes basically apparent by an extension on a material support?In Cours du Bauhaus, a compilation of Kandinsky notes, appear terms such origin, transformation, adaptation, movement, evolution, etc. There are concepts extracted from studies and experiments linked with natural sciences. Kandisnky transfers the results of the experimentation about transformations that arise in alive organisms in pictorial work. Kandinsky manuscripts recently published, confirm his interest about evolutionist theories. Kandinsky knew the principles proposed by Darwin. Although seems that he accepts the Darwinian idea of a common ancestor, in a text of Punkt und Linie will assert that laws that govern the formal similarities between living beings, are not directly applicable in artistic work. In a Cours du Bauhaus note emphasizes the importance of the vitalism, a doctrine that supports that vital phenomenons have a singular and specific character that moves away every conception that reduces to mechanical or physic-chemical phenomenons. The bibliographic reference of this note is Die Kultur der Gegenwart, the same publication of which he extracts some of the outlines that appear in Punkt und Linie. It is the only time that appears the name of Herni Bergson in a Kandinsky text.Kandinsky develops a representation system from a theoretical writings that see in the change the deeper reality of things, a formal grammar in which evolution form will substitute each forms made one following the other, and in which the movement has more than in the successive positions of a mobile. Darwinian natural selection theory, tried to explain species adaptation to environment. Kandisnky will define laws which will regulate adaptation between formal elements. One shape is the result of a mutual adaptation between the material and the psychological. Kandinsky introduces in some of his works a device that causes movement: the pendulum, a device that fits perfectly to the mechanisms that our intellect uses to reproduce movement. The pendulum is adapted to the observer's interior self, a place where the given time is true, never outside this one. The pendulum is in the Kandinskyan system, the paradigmatic formal element of the movement.Kandinskyan grammar is not based in laws that require a previous knowledge. The outlines of the formal elements are enough permeable to make one self insert its action and modify it according to his needs. Kandinsky does not pretend to show us some events but to attend them; we do not have to observe something that happens in front of us, because what happens in front of us is ourselves. We witness a swing between two ends apparently opposites, then we witness the change, we are in the movement. Is the moment of the reciprocal adaptation between our and the composition time. Kandinskyan language, based on the action, combines in present.We will conclude saying that a Kandinsky drawing is not a representation of something steady but a views succession: the result of an effort placed in the future. Although we are on a material support, the shapes had not lost their contact with movement yet. The formal elements we perceive are given in the future. Are drawings that sink in a temporal dimension rather than a space dimension: they last because we make them last in our duration. We will end also saying: Essai sur les données immédiates de la conscience, "Introduction à la métaphysisque" and L'Évolution créatice, Bergson documents, are primary sources that configure Kandinsky work.

Respiratory Monitoring System Based on the Thoracic Expansion Measurement

Araujo Cespedes, Fabiola 01 January 2012 (has links)
The purpose of this reasearch was to develop a respiratory monitoring system using a reflective object sensor based belt to measure the thoracic expansion of a neonatal for future application at the medical center of the Universidad Evangelica Boliviana (UEB). This medical center, being founded by the UEB University, is dedicated to help and serve the poor and currently has no respiratory monitoring system. The methodology used was first to build and test the respiratory sensor belt and test the relationship between the blet expansion and the voltage generated. The, to incorporate the respiratory sensor belt in a system that would allow individual testing as well as group testing in a wireless network. The system was simulated using an expandable plastic container that was expanded and extracted periodically, registering the results in a MATLAB software. The system gave successful results and generated the frequency results of each cycle, average frequency and deviation frequency. The system demonstrated to be reliable and to have repeatable results.

Net Migration Between Different Settlement Types In Turkey, 1985-90

Sahin Hamamci, Nihan 01 August 2003 (has links) (PDF)
In the past studies covering 1965-90, it is observed that net migration was from villages and district centers towards province centers. Although the net migration trend throughout the period was almost constant for the villages and the province centers, the role of the district centers changed in later periods. Previously, the district centers were transient settlements in terms of net migration with resultant almost zero net migration. However, in later years, they began to have net out-migration in significantly increasing numbers, because net in-migration from the villages decreased and net out-migration to the province centers increased. The increase in the net migration from district centers to province centers and the gradual loss of the importance of the district centers (towns) occurred not only in Turkey but also in the other developing countries, especially in 1990&amp / #8217 / s. The aim of this thesis is to study the net migration trends and patterns of the three different settlement types namely, province centers, district centers and villages of Turkey during 1985-90. In this study, the descriptive analyses which were carried out on the net migration rates of the provinces and three settlement types clearly indicate the regional disparities between west-east and south-north of Turkey. For all of the three settlement types, the provinces having the highest net in-migration rates are located along the Western and Southern coastal zones whereas the provinces having the largest net out-migration rates are located in the East, North East and South East regions.

N/A / United States Vital Interests: Does Taiwan Measure Up?

司徒尚禮, Charles Andrew St.Sauver Unknown Date (has links)
It has been 60 years since the Republic of China’s government fled to the island of Taiwan during the Chinese Civil War. Taiwan’s rival on mainland, the People’s Republic of China, is of the view that there is only one China and Taiwan is part of China. In recent years the mainland has reiterated and then formalized its policy to use force if necessary against Taiwan in the name of reunification. Caught between these positions is the United States. Since the Republic of China’s arrival on Taiwan, the United States has provided an external assurance of security for Taiwan. As the People’s Republic of China’s economic, military, and political power grows it will increasingly have the ability to shape issues in East Asia and beyond, therefore challenging United States’ national vital interests. Vital interest is defined as an issue at stake which is so fundamental to the political, economic, and social well being of the United States that it cannot be compromised even if defending it requires military action. Is Taiwan truly a vital interest? Donald Nuechterlein’s 16 national vital interest factors are used to evaluate this question from two angles: a literature review and questionnaire. Much like the United States’ described position of ambiguity toward Taiwan, this study is also inconclusive to the core question, Taiwan’s position as a vital interest in terms of US policy. This conclusion was unexpectedly reached because both analyses scored a virtual 1 to 1 ratio between value and potential costs/risks, thereby providing no differentiation. However, the analysis did reveal issues that should be seriously considered by policy makers when making any final determination on the Taiwan question. Criteria such as the economic and military costs of war are important as well as the fact that Taiwan is fellow democracy and important cog in the regional balance of power. Finally, recommendations provided for more in depth study on Taiwan as a vital US interest may reveal more definitive answers.

Future time perspective and satisfaction with life across Iife span / Perspectiva temporal futura y satisfacción con la vida a lo largo del ciclo vital

Martínez, Patricia 25 September 2017 (has links)
The present  research studies Satisfaction  with  Life and Future Time Perspective, in itsdifferent dimensions (goals, temporal location of goals and temporal altitudes), from adolescence to elder ages. This study evaluated 570 males and females between 16 and 65 years old, from two different socioeconomic levels in Lima, Peru, through a non­ experimental, evolutionary transversal design. Tools used in this research were the Motivational Induction Method (MIM) and the Temporal Altitudes Scale (TAS) by Nultin (1985), and the Satisfaction with Life Scale (SWLS) by Pavot & Diener (1993). Results show that there are significan! differences on the construction and temporal Iocation of goals, altitudes towards present, past and future and in the levels of Life Satisfaction due to the variable age. lt was also found that socioeconomic leve! influences these processes more than gender. / Este estudio aborda los constructos de Perspectiva Temporal Futura, en sus diferentes dimensiones (Metas, ubicación temporal de las metas y Actitudes Temporales) y de Satisfacción con la vida, desde la adolescencia en adelante. A través de un diseño no experimental, evolutivo transversal, se evaluó a 570 personas de ambos sexos entre los 16 y los 65 años, de dos niveles socioeconómicos de Lima, Perú. Los instrumentos utilizados fueron el Método de Inducción Motivacional (MIM), la Escala de Actitudes Temporales (TAS) de Nuttin (1985) y la Escala de Satisfacción con la Vida (SWLS) de Pavot y Diener  (1993). Los resultados muestran que la edad supone diferencias importantes en la construcción de las metas y su ubicación temporal, así como en las actitudes hacia el presente, pasado y futuro y en los ni veles de satisfacción. Asimismo, evidencia que el nivel socioeconómico, más que el sexo, influye en estos procesos.
