This study investigated how advertisers from the creation area of large advertising agencies perceive and characterize their creative process. Thirteen Brazilian professionals were interviewed using semi-structured interviews. Data were analyzed by content analysis. Results indicate that several stages of the creative process overlap, such as the incubation period of one job functioning as the preparation for the next. Motivating factors include pleasure of the act of creating, media visibility and its social reach. Limiting factors include the agencies’ excessive departmentalization, reduced deadlines, and the clients’ subjectivity influencing the advertisement approval.

We have determined quantitatively Coliforms and Enterococcus in the mollusk Aulacomya ater "choro", as an index of human enteric contamination during the preparing process of "cebiche". There have been processed 1152 specimens from Lima and Callao markets. The highest average of contamination for both microbial groups, in choros uncooked (part a), from markets situated in places with little hygiene' conditions and more population. The environmental temperature in summer’ months show us an increscent of this kind of microbial organisms. The temperature of cooking from specimens before preparing “cebiche” (part b), gets to kill all the microbial forms, reappearing Coliforms (part c), as a result of the addition of condiments. The lemon juice did not actuate as effective bactericidal.

The existence of early and timely resolution processes for matters of simple processing is now a reality. With the introduction of orality in judicial processes, the great challenge lies in obtaining true justice as a quality public service. What simple processes are solved in a differentiated way is not a problem, but a solution. The discussion now focuses on how to make it possible and what should be respected, beginning from the state criminal policy, the real reasons behind the reform, judicial guarantees and, finally, opportunities for improvement.

Technological development accompanies the progress of human civilizations and is closely related to their social and cultural characteristics. Currently, the rise of technology and, especially, of information and communication technologies determines to a large extent the way in which we relate to each other and how we approach aspects such as politics, economics and education, among others. In the organizational context, technology is an indicator of the degree of maturity and competitiveness of companies and provides them with the capacity to respond to market demands and be sustainable over time. However, it is notorious in o...

En los orígenes de la ciencia de la computación todo el énfasis estuvo puesto en desarrollar sistemas que automatizaran tareas que se hacían manualmente. Este era suficiente desafío. En la actualidad, se han automatizado muchas tareas y el gran desafío es cómo mejorar la capacidad de los sistemas para alcanzar nuevos requerimientos: agregar nuevas interfaces, combinar múltiples fuentes de datos en una sola, interactuar con dispositivos móviles y reemplazar viejas aplicaciones con nuevas. La tendencia de hoy es hacia un paradigma orientado a los procesos, donde las aplicaciones cubren la actividad global de la empresa y las herramientas son los BPMS (Business Process Management Systems o Sistemas de Gestión de Procesos de Negocio). Los modelos actuales resultan insuficientes porque son pobres en su integración y se orientan a describir datos y transacciones. El cambio de enfoqu...

This paper analyzes the current estate of the diverse integration processes in South America; their different orientations and emphasis, their common denominators and divergences, but mainly, their necessity to impulse efforts and synergies searching for their convergence in a great sub regional integration project. The institutional convergence of the diverse integration processes set in motion in South America, may serve as an efficient instrument to achieve greater levels of economic and social well-being, deepening and improvement of the regional democratic standards and forge a geopolitical block that allows us to transform South America in to an international actor that takes advantage and manages the opportunities generated by globalization better.

Computed tomography (CT) is a breakthrough technology used in medicine for diagnostic diseases. The same technique is used in other areas, such as aerospace chemistry, Radio astronomy, etc. The main objective of the CT is to reconstruct the internal part of an object without having to open it as a non-destructive test. To achieve this purpose, the CT uses the attention that X-rays undergo through this object with the information, the inner part of the object is reconstructed, that is to say the CT is an inverse problem.In this article uses the Fourier transform for the reconstruction of the internal part, for it is directly part of a continuous model, representing the density at the point (x, y) of a section, with a function p = p(x, y); and even though p is not required to be continuous, the Fourier method is more efficient and a better, more regular result is obtained p.

The objective of the research work was to propose a teaching method that allowed the self-management of knowledge related to the zoology of invertebrates by the students of the 3rd year of the Bachelor of Education career, comparing in-person learning vs. those not in attendance. For the development of the research, information gathering and processing methods were used, which allowed us to verify the shortcomings in terms of the use and elaboration of this type of teaching medium, for the teaching-learning process from the non-face-to-face modality. The illustrations were made to correspond with the pedagogical and hygienic requirements, which contributed to the aesthetic education of the students and raised the interest in the didactic material. Suggestions and arguments made by different experts were taken into consideration, which were largely the basis for the realization of the wor...

Health care is an institutionalized activity under the control of the State. Current public policy offers benefits limited to scientific progress and the use of technology for its potential to solve highly complex problems. However, in public hospitals, the distance between the discourse and the concretion of care is observed, whose epitome is human praxis. This work is the result of a research project of the Master’s and Doctoral Program in Medical, Dental and Health Sciences of the National Autonomous University of Mexico (UNAM). Uses the ethnographic method in the clinical context. Findings open the discussion on the scope and implications of how technology is used in the clinical context. Currently, the use of technology is a topic of research in the Department of History and Philosophy of Medicine of the UNAM, coordinated by Professor Alfredo Paulo Maya.

Este artículo presenta una técnica para mejorar el proceso de diseño industrial de transistores de microondas, basado en un diseño de experimentos mejorado (DOE) y un modelado electrotérmico (MET) expandido. El diseño de experimentos DOE permitió centrar el diseño a través de variaciones en parámetros específicos, para evitar complejas simulaciones electromagnéticas de acoplamiento mutuo entre los cables dentro del mismo transistor, que generalmente en herramientas CAD convencionales presentan un elevado costo computacional. El modelo electrotérmico mejorado utilizando la técnica de voltajes efectivos posibilitó predecir no solo el autocalentamiento, sino también las impedancias apropiadas para la máxima potencia de salida y la máxima eficiencia del transistor. De esta manera fue posible elegir las condiciones de operación que garantizaran un reducido autocalentamiento...

La tesis presentada ha sido desarrollada en el marco del concepto de Responsabilidad Social Corporativa (RSC}, analizando la importancia de la Licencia Social para Operar (LSO) en el contexto de la actividad extractiva minera en la categoría de Gran Minería del Perú. Esta investigación surge por una inquietud asociada con la conflictividad social que circundaba al Proyecto Minero Conga desde el año 2011. La pregunta que guía el desarrollo de esta investigación surge como el resultado de la contradicción que se da entre sectores que se oponen al desarrollo de la actividad extractiva de grandes empresas mineras y el beneficio económico que estas actividades generan para el país. Se definieron dos casos de estudio, circunscritos al ámbito de influencia de dos empresas que componen este rubro de gran minería, la empresa Yanacocha en Cajamarca y la empresa Sociedad Minera Cerro Ve...

The emerging international system in the twenty-first century is characterised by a new phase of globalization in which, largely due to the explosion of information and communication technologies, the role and activity of a variety of actors –outside and within states– has been significantly strengthened. While the states remain as the main actors of the world system, the current configuration of the international order no longer responds to the Westphalian state-centric paradigm that shaped international relations until the end of the twentieth century. In this new scenario, the role of subnational actors is increasingly active, which opens a window of opportunity for developing nations to improve their competitive and cooperative insertion in the international system at both regional and global levels.
