Ingenieros del siglo XXI: importancia de la comunicación y de la formación estratégica en la doble esfera educativa y profesional del ingeniero
Kindelán, M.a Paz,Martín, Ana M.a
Arbor : Ciencia, Pensamiento y Cultura , 2008, DOI: 10.3989/arbor.2008.i732.218
Abstract: The rise of worldwide communication networks and information technologies have redefined the concept of education in all fields. In engineering, a new educational paradigm can be glimpsed where the development of generic skills is prioritized in the curriculum and professional training of university students and practitioners. Skills such as the ability to successfully communicate orally and in writing, to operate with a multidisciplinary perspective in decision-making and problem-solving, to work in teams, and to become involved in lifelong learning, among others. The relationship among communication, training and lifelong learning is a key point in the profile of the engineer in this century. The challenge for those who are committed to the new paradigm, both teachers and trainers in the private sector, is to be able to incorporate the three dimensions into the educational process, so that it contributes to a better preparation of the individual to perform in the workplace from a human and professional point of view. El nacimiento de las redes mundiales de comunicación y las tecnologías de la información han redefinido el concepto de la educación en todos los ámbitos. En el terreno de la ingeniería se vislumbra un nuevo paradigma educativo donde se prioriza el desarrollo de destrezas genéricas, entre las que destacan la habilidad para comunicarse eficazmente de forma oral y escrita, para funcionar con una perspectiva multidisciplinar en la toma de decisiones y la resolución de problemas, el énfasis en el trabajo colaborativo y la capacidad para involucrarse en un aprendizaje de por vida. La interrelación entre comunicación, aprendizaje y formación es un factor fundamental en el perfil del ingeniero del nuevo siglo. El desafío para quienes nos hallamos comprometidos con este paradigma –tanto docentes como formadores en el sector privado– está en saber integrar estas tres dimensiones en el proceso educativo, de tal modo que éste contribuya a una mejora del individuo en el ejercicio de su actividad desde una perspectiva humana y profesional.

Abstract: studies regarding the spatial orientation of social insects (bees, termites and ants) concerning their search for food, foraging and transporting it have received considerable attention during the last few years. such studies have been aimed at learning so as to apply it to robotics (multiagents) and ecological pest control. however, little is known about the types of orientation mechanism and their integration in such insects. this article presents some geomagnetic field detection studies dealing with controlling them by magnetotaxis or orientation experiments in sasaima (cundinamarca) to formulate an ecological management proposal for ants from this species which greatly affect colombian agriculture.

Abstract: La preocupación creciente de los trabajadores hacia los posibles efectos nocivos de la exposición a campos electromagnéticos, está suponiendo una percepción desproporcionada de los riesgos derivados de la exposición. En la actualidad, no existe evidencia científica sobre dichos efectos nocivos, siendo aconsejable la vigilancia sobre las exposiciones que están fuera de los límites de seguridad. Desde este Servicio de Prevención y en colaboración con el Servicio de Física Médica, hemos elaborado un procedimiento que garantice, mediante criterios preventivos básicos, la seguridad y salud de los trabajadores que manejan equipos emisores de radiaciones no ionizantes, en nuestro hospital y centros de especialidades. Para la elaboración de este procedimiento hemos revisado la literatura científica relativa a los efectos de los campos electromagnéticos sobre la salud, reuniones periódicas de trabajo entre ambos servicios, identificación y ubicación de los equipos de radiaciones no ionizantes, y asesoramiento por expertos en la materia. El procedimiento establece medidas de control para los trabajadores, y medidas de control para los equipos. Con la finalidad de conseguir una buena difusión e implantación de dicho procedimiento, hemos elaborado dípticos y carteles, donde reflejamos las medidas de control para trabajadores y equipos: Onda Corta, Microondas, Magnetoterapia, Resonancia Magnética Nuclear, Láser y Ultravioleta El procedimiento con sus carteles explicativos ha sido distribuido específicamente por servicios, realizando formación e información de los trabajadores que maneja dichos equipos. Employee increasing concern about possible dangerous effects of the exposure to electromagnetic fields is meaning a distorted perception of the exposure related risks. Currently, there is no scientific evidence of the dangerous effects mentioned although surveillance over the exposures out of the safety limits is recommended. Within this Prevention Department in cooperation with The Medical Physics Department a procedure based on basic preventive criteria has been elaborated to guarantee health and safety of the employees who handle non-ionizing radiation emitting equipment in our hospital and specialized centers. To draw the procedure: scientific literature related to the electromagnetic fields effects over health has been checked, periodical working meetings have been held between both above mentioned departments; non-ionizing radiation equipment have been identified as well as the places they are based or used; and expert people advice has been used. The procedure
