Abstract: a lecture was presented by the author at the democratic opinion forum on health teaching and research, organized by mexico′s national health institutes coordinating office, at national cardiology institute "ignacio chavez", where he presented a critical review of the conventional classification of basic and applied science, as well as his personal view on health science teaching and research. according to the author, "well-conducted science" is that "generating reality-checked knowledge" and "mis-conducted science" is that "unproductive or producing 'just lies' and 'non-fundable'. to support his views, the author reviews utilitarian and pejorative definitions of science, as well as those of committed and pure science, useful and useless science, and practical and esoterical science, as synonyms of applied and basic science. he also asserts that, in mexico, "this classification has been used in the past to justify federal funding cutbacks to basic science, allegedly because it is not targeted at solving 'national problems' or because it was not relevant to priorities set in a given six-year political administration period". regarding health education and research, the author asserts that the current academic programs are inefficient and ineffective; his proposal to tackle these problems is to carry out a solid scientific study, conducted by a multidisciplinary team of experts, "to design the scientific researcher curricula from recruitment of intelligent young people to retirement or death". performance assessment of researchers would not be restricted to publication of papers, since "the quality of scientific work and contribution to the development of science is not reflected by the number of published papers". the english version of this paper is available at: http://www.insp.mx/salud/index.html
Ciencia básica y ciencia aplicada
Pérez-Tamayo Ruy
Salud Pública de México , 2001,
Abstract: En el contexto de una intervención en el Foro de Consulta Democrática de la Coordinación de los Institutos Nacionales de Salud sobre Ense anza e Investigación en Salud, realizado en el Instituto Nacional de Cardiología Ignacio Chávez, se hace una revisión crítica de la clasificación convencional de la ciencia en básica y aplicada; además, se analiza lo que deberían ser la ense anza y la investigación en salud. Para apoyar su propia clasificación de la ciencia en "bien hecha", la cual "genera conocimientos verificables sobre la realidad" y la "mal hecha", improductiva o productora de "puras mentiras" y "no debe patrocinarse", el autor revisa las definiciones utilitaristas y peyorativas como las que establecen ciencia comprometida y ciencia pura, ciencia útil y ciencia inútil, y ciencia práctica y ciencia esotérica, como sinónimos de ciencia aplicada y ciencia básica y afirma que, en México, esta diferenciación "para lo único que ha servido en el pasado es para justificar la reducción en el apoyo oficial a la ciencia básica, porque no estaba dirigida a resolver ′los problemas nacionales′o porque no caía en las prioridades establecidas en ese sexenio". En cuanto a educación e investigación en salud reconoce que el programa actual de formación de investigadores tiene una eficiencia muy baja y propone un estudio científico crítico, realizado por un equipo de especialistas, interdisciplinario, "para integrar la carrera del investigador científico desde la captura de la juventud inteligente hasta la jubilación o muerte del investigador" y para el cual la evaluación de la eficiencia del apoyo a sus proyectos de investigación no se restrinja a si se publicó o no un artículo "pues la calidad del trabajo científico y la contribución de un investigador al desarrollo de la ciencia no es nada más el número de sus publicaciones".

La exploración de una frontera natural en el siglo XIX
Tamayo Pérez, Luz María Oralia;
Investigaciones geográficas , 2005,
Abstract: the rio bravo o grande del norte is the most important natural border between mexico an the united states. in the period 1853-1854 four mexican engineers explored a section of river between the two countries like part of a demarcation work. they had to indicate in maps its bed as it was specified in the guadalupe hidalgo's treaty, however the commissioners confronted serious problems, before they achieved the best maps of the bravo river from laredo until its mouth near to matamoros. in their observations they left testimony of the vegetation and of some climatic variables which allows to analyze probable changes in the area.
Matriz dise?ada en toxicología ocupacional
Tamayo Rivas,Sheila; Argota Pérez,George;
MEDISAN , 2012,
Abstract: a matrix was designed to prevent the risk in occupational toxicology, structured in 3 evaluation sections (presumed risk, advice risk and risk of working conditions and damages to health). five menus were considered in the first section (sector, chemicals, referred toxicity, biomarkers and sentinel events); 6 in the second section (frequency of exposure, length of exposure, proximity to the source, means of protection and influence of posts) and 2 in the third one (evaluation of working conditions and damages to health). given that it is a new management tool to estimate the toxicological risk, it contributes to preserve health in the work place.
Factor de condición biológico-ambiental en la Gambusia punctata y sus efectos para el control biológico larval
Argota Pérez,George; Tamayo Rivas,Sheila;
MEDISAN , 2012,
Abstract: in this paper the biological condition factor was evaluated in the species gambusia punctata as an expression of environmental damage of san juan river in santiago de cuba, for which the total length of the fish was related to the total weight. two study sites were selected in the upper and lower river basins, and samplings were performed during the dry season of 2011. individuals of both sexes were chosen which biometrically measured between 1.8 and 3.1 cm in total length and 2 class intervals were established. the fishes living in the upper river had higher biological condition factor (0.068 > 0.038). it was concluded that given the values of this factor, the environmental quality of the ecosystem affects the development of the species, which could influence their predatory capacity and therefore as biological control of mosquito larvae.
Matriz dise ada en toxicología ocupacional Matrix designed in occupational toxicology

Abstract: Se dise ó una matriz para prevenir el riesgo en toxicología ocupacional, estructurada en 3 secciones de evaluación (riesgo presumible, riesgo de asesoría y riesgo de condiciones de trabajo y da os a la salud). Se consideraron 5 menús en la primera (sector, agentes químicos, toxicidad referida, biomarcadores y eventos centinelas); 6 en la segunda (frecuencia de la exposición, duración de la exposición, proximidad a la fuente, medios de protección e influencia de puestos) y 2 en la tercera (evaluación de las condiciones de trabajo y da os a la salud). Toda vez que constituye un nuevo instrumento de gestión para estimar el riesgo toxicológico, contribuye a preservar la salud laboral.

Factor de condición biológico-ambiental en la Gambusia punctata y sus efectos para el control biológico larval Environmental and biological condition factor in the Gambusia punctata and its effects for larval biological control

MEDISAN , 2012,
Abstract: En este artículo se evaluó el factor de condición biológico en la especie Gambusia punctata como expresión de da o ambiental del río San Juan de Santiago de Cuba, para lo cual se relacionó la longitud total de los peces con respecto al peso total. Fueron seleccionadas 2 estaciones de estudio en las cuencas alta y baja del río y los muestreos se realizaron durante la época poco lluviosa de 2011. Se escogieron individuos de ambos sexos, que biométricamente midieron entre 1,8 y 3,1 cm de longitud total y se establecieron 2 intervalos de clases. Los peces que habitaron en la parte alta del río presentaron mayor factor de condición biológico (0,068>0,038). Se concluyó que dado los valores de dicho factor, la calidad ambiental del ecosistema afecta el desarrollo de la especie, lo cual podría influir en su capacidad depredadora y, por tanto, como control biológico de larvas de mosquitos.
