Objetives: To determine the level of knowledge, attitudes and practices with respect to the Papanicolaou cervical smear test (Pap), to find association between age and learning level, and to describe the characteristics on Pap’s periodic practice. Design: Analytical and cross-sectional study. Setting: San Bartolome Mother and Child National Teaching Hospital. Patients: Women in fertile age. Interventions: Structured questionnaire, self-developed, from November 2005 through January 2006. X2 , t student, Anova and OR were used for statistical analysis. Main outcome measures: Level of knowledge, attitudes and practices on Papanicolaou smear, as well as associations and characteristics on its periodical practice. Results: Of 501 surveys, 63% showed low level of knowledge, 66% had an unfavorable attitude, and 71% an incorrect practice of Pap smear; OR between knowledge level and correct pra...

La presente investigación contó por objetivo determinar la relación entre la motivación educativa y la satisfacción académica en el estudiante de Educación en la Universidad Nacional de Educación Enrique Guzmán y Valle, Lima – 2016. La muestra correspondió a 100 estudiantes universitarios de la carrera de Educación, eligiéndose a conveniencia de acuerdo a la accesibilidad a los estudiantes. Esta investigación siguió un enfoque cuantitativo, de diseño no experimental y de nivel descriptivo correlacional. Los instrumentos fueron cuestionarios. El diseño estadístico involucró la medición de frecuencias y porcentajes, así como la aplicación del Rho de Spearman, mediante el uso del paquete estadístico SPSS versión 22. Como conclusión se determinó que existe una relación significativa entre la motivación educativa y la satisfacción académica en el estudiante de E...

Primal or dual strong-duality (or min-sup, inf-max duality) in nonconvex optimization is revisited in view of recent literature on the subject, establishing, in particular, new characterizations for the second case. This gives rise to a new class of quasiconvex problems having zero duality gap or closedness of images of vector mappings associated to those problems. Such conditions are described for the classes of linear fractional functions and that of quadratic ones. In addition, some applications to nonconvex quadratic optimization problems under a single inequality or equality constraint, are presented, providing new results for the fulfillment of zero duality gap or dual strong-duality.
