Abstract: the work that we presented centers to study the characteristics that must reunite the basic pillars of the creativity: the educator, the climate or pedagogic, because it is not tried single to transfer to the school methods or tactics that look for novel and original products. more than ever, when one is to teach creativity, as much the educator, the student, the atmosphere, the resources or the methods they have to be creative. in the first place the educator, like scene director, must have between its intentions first, looking for a process of creative education-learning. to teach creativity is perhaps one of the most complicated goals in the educative system. because it looks for to foment the divergent thing in convergent surroundings; the indefinite thing in a well-known system that it looks for to transmit the defined thing and. because it demands that the educator is placed in a unknown and uncertain position: of desprotection, of question, uncertainty, ignorance before which the student is going to him to propose. in conclusion and according to which lowenfeld and lambert in 1980 considered the most accepted aspect with respect to the development of the creativity: ?the best preparation for the creation is the same creation.

The used total sample was of 90 students, pertaining to a preschool and Primary School, of the region of the Altiplano (municipality of Jumilla) in the Region of Murcia (Spain). With this study we want to demonstrate that the implementation of a program that develops the divergent thought, is going to influence favorably in the creativity of the students. The results indicate a significant improvement in the fluidity factors, flexibility and originality, in the groups to which it was applied to the program of improvement of the creativity of Renzulli, specially in the students of the first cycle of Primary Education. What the investigation confirms is that a program of development of the creativity, represents an instrument for teachers and children who provide tasks and materials with which to try a variety of ways to express its creative potential.

Abstract: a descriptive cross sectional study was undertaken with the geriatric population of "ana betancourt" polyclinic of playa municipality. 2 139 older adults aged 65 and over were selected. surveys were done to collect their general data and 2 tools were applied to measure their cognitive capacity: the mini-mental status examination or folstein's test and the scale rating dementia. in a second phase of the research, a sociodemographic survey was applied to the cases that during the first stage were concluded as possible dementias by using the diagnostic criteria of dsm-iv for alzheimer primary degenerative dementia and the criteria summarized by the national institute of neurological disorders of communication and cerebrovascular accidents and by the association for alzheimer's disease and related disorders (nincds-adrda). the number of patients with demential syndrome amounted to 116 aged persons, accounting for a prevalence of 5.42 %. alzheimer's disease was the most frequent cause with 81 patients (70 %). there was a predominance of the mild clinical form and the age group 80-84 was the most affected. it prevailed among the white elderly with lower intellectual level.
Desarrollo tecnológico, impacto sobre el medio ambiente y la salud Technological development, environmental impact and health

Revista Cubana de Higiene y Epidemiología , 2011,
Abstract: El mejoramiento en las condiciones de vida provocado por el desarrollo tecnológico incrementó la población mundial, el gasto de energía, la producción de alimentos y los de bienes de consumo. A su vez, se aceleró la contaminación ambiental, la deforestación, el surgimiento de las grandes ciudades y otros fenómenos que se han convertido en un problema para la humanidad. Nos proponemos mostrar la problemática actual existente entre el desarrollo tecnológico su repercusión sobre el medio ambiente, la salud humana así como las posibles vías para el encuentro de soluciones. La contaminación ataca la salud humana, por el agua o el aire; por la merma de los rendimientos de cultivos; también en la salud del ganado y en la pesca. Se han liberado cantidades de CO2 y de otros gases de efecto invernadero que han provocado un exceso de mortalidad cifrado en 70 000 defunciones en Europa, y se agravan las enfermedades cardiovasculares y respiratorias con 1,2 millones de defunciones cada a o en zonas urbanas. Los niveles de polen y otros alérgenos son mayores lo que puede provocar afecciones alérgicas como el asma, que afecta a unos 300 millones de personas. Los desastres naturales se han triplicado con creces desde los a os sesenta; cada a o esos desastres causan más de 60 000 muertes. La creciente variabilidad de las precipitaciones afectará el suministro de agua dulce y lo que hará peligrar la higiene, aumentar el riesgo de enfermedades diarreicas, que matan a 2,2 millones de personas cada a o. Se ha multiplicado por dos la frecuencia de sequías extremas y por seis su duración media, lo que ha incrementado la hambruna. Es probable que se prolonguen las estaciones de importantes enfermedades transmitidas por vectores, como la esquistosomiasis, la malaria y el dengue. La Cumbre celebrada en Copenhague evidenció el caos de los gobiernos mundiales, dado que no se alcanzó consenso y se postergó para el 2010 la firma de un tratado vinculante. En el 2010 en la conferencia de Cancún se estableció el "Fondo Verde" para ayudar a los países más pobres a enfrentar el cambio climático y algunos compromisos políticos, pero no se llegó al tratado vinculante. Es necesario entender la urgencia de las medidas y la importancia de la participación de todos en el cuidado de los recursos naturales. The improvement of living conditions caused by technological development increased world population, energy expenditure, food production and consumer goods. Turn accelerated environmental pollution, deforestation, the rise of big cities and other phenomena that have become a problem for humanit

Abstract: Se realizó un estudio descriptivo, de corte transversal, con la población geriátrica del policlínico "Ana Betancourt", del municipio Playa, de la cual se seleccionan los 2 139 adultos mayores de 65 a os y más. Se utilizaron encuestas que recogen sus datos generales, y se les aplicaron 2 instrumentos para medir su capacidad cognitiva: el Mini- Mental Status Examination o Test de Folstein y la escala de clasificación clínica de las demencias (Scale Raiting Dementia). En una segunda fase de la investigación aplicamos una encuesta socio demográfica a los casos que en la primera fase se concluyeron como posibles demencias, utilizándose los criterios diagnósticos del DSM-IV para la demencia degenerativa primaria tipo Alzheimer, y los criterios resumidos del Instituto Nacional de Trastornos Neurológicos de la Comunicación y de Accidentes Vasculares Cerebrales y por la Asociación para la Enfermedad de Alzheimer y Trastornos Conexos (NINCDS-ADRDA). Se encontró una cantidad ascendente a 116 ancianos con síndrome demencial, lo que constituye una prevalencia de un 5,42 %, y fue la enfermedad de Alzheimer la causa más frecuente con 81 pacientes (70 %). Prevaleció la forma clínica ligera, y el grupo de edades más afectado fue el de 80 a 84 a os. Predominó en los ancianos con menor nivel intelectual y de la raza blanca.
