Promoción de la Salud Sexual y Reproductiva para Estudiantes Universitarios Ecuatorianos/Promotion of Sexual and Reproductive Health for Ecuadorian University Students

Introducción: disponer de información científica sobre sexualidad es un derecho que contribuye a alcanzar un nivel elevado de salud sexual y reproductiva. Materiales y Métodos: con el objetivo de promocionar la salud sexual y reproductiva en universitarios, se realizó una investigación de desarrollo tecnológico, en la Escuela Superior Politécnica de Chimborazo en Ecuador, utilizándose el modelo PRECEDE – PROCEDE. Las primeras fases permitieron identificar las necesidades educativas en dos grupos de estudiante, agrupados en la Facultad de Salud Pública y del resto de las facultades; a partir de ello, con participación de estudiantes pares, se diseñó y aplicó la estrategia. La evaluación se realizó mediante un estudio cuasi experimental con un diseño de antes-después con grupo control. Resultados: se identificaron deficiencias en sus conocimientos, mitos y creencias distorsionadas; se evidenció comportamientos de riesgo en su sexualidad; no se demostró que los estudiantes del área de salud tuvieran en gran magnitud, diferentes necesidades que el resto de las facultades. La estrategia educativa diseñada en correspondencia a las necesidades fue construida por jóvenes para jóvenes; contó con recursos metodológicos y materiales para fomentar la salud sexual y reproductiva. Conclusiones: la estrategia de promoción de salud, favoreció la educación sexual de los estudiantes universitarios incluidos en la investigación, al lograrse cambios en variables generadoras de conductas sexuales saludables.

Materials and Methods: With the objective of promoting sexual and reproductive health in university students; a technological development research was carried out, in the Polytechnical Superior School of Chimborazo in Ecuador, the PRECEDE - PROCEDE model was used, the first phases allowed to identify the educational needs in two groups of students grouped in: Faculty of Public Health and the rest of the faculties, based on this, with the participation of peer students, the strategy was designed and applied. The evaluation was carried out through a quasi-experimental study with a before-after design with a control group. Results: Deficiencies in their knowledge, myths and distorted beliefs were identified, risky behaviors in their sexuality were evidenced, it was not demonstrated that the students of the health area had in great magnitude, different needs than the rest of the faculties, the educational strategy designed in accordance with the needs was built by young people for young people,it had methodological and material resources to promote sexual and reproductive health. Conclusions: The health promotion strategy favored the sexual education of the university students included in the research, to be achieved changes in variables that generate healthy sexual behaviors.

Single Stellar Populations in the Near-Infrared - I. Preparation of the IRTF spectral stellar library

We present a detailed study of the stars of the IRTF spectral library to understand its full extent and reliability for use with Stellar Population (SP) modeling. The library consist of 210 stars, with a total of 292 spectra, covering the wavelength range of 0.94 to 2.41 micron at a resolution R = 2000. For every star we infer the effective temperature (Teff), gravity (logg) and metallicity ([Z/Zsun]) using a full-spectrum fitting approach in a section of the K band (2.19 to 2.34 micron) and temperature-NIR colour relations. We test the flux calibration of these stars by calculating their integrated colours and comparing them with the Pickles library colour-temperature relations. We also investigate the NIR colours as a function of the calculated effective temperature and compared them in colour-colour diagrams with the Pickles library. This latter test shows a good broad-band flux calibration, important for the SP models. Finally, we measure the resolution R as a function of wavelength. We find that the resolution increases as a function of lambda from about 6 angstrom in J to 10 angstrom in the red part of the K-band. With these tests we establish that the IRTF library, the largest currently available general library of stars at intermediate resolution in the NIR, is an excellent candidate to be used in stellar population models. We present these models in the next paper of this series.Comment: 17 pages, 19 figures. Accepted for publication in Astronomy and Astrophysic

A SAURON look at galaxy bulges

Kinematic and population studies show that bulges are generally rotationally flattened systems similar to low-luminosity ellipticals. However, observations with state-of-the-art integral field spectrographs, such as SAURON, indicate that the situation is much more complex, and allow us to investigate phenomena such as triaxiality, kinematic decoupling and population substructure, and to study their connection to current formation and evolution scenarios for bulges of early-type galaxies. We present the examples of two S0 bulges from galaxies in our sample of nearby galaxies: one that shows all the properties expected from classical bulges (NGC5866), and another case that presents kinematic features appropriate for barred disk galaxies (NGC7332).Comment: 4 pages, 3 figures, accepted for publishing in AN (refereed conf. proc. of the Euro3D Science workshop, IoA Cambridge, May 2003

Inelaticity in hadron-nucleus collisions from emulsion chamber studies

The inelasticity of hadron-carbon nucleus collisions in the energy region exceeding 100 TeV is estimated from the carbon-emulsion chamber data at Pamirs to be $= 0.65\pm 0.08$. When combined with the recently presented data on hadron-lead nucleus collisions taken at the same energy range it results in the $K\sim A^{0.086}$ mass number dependence of inelasticity. The evaluated partial inelasticity for secondary ($\nu > 1$) interactions, $K_{\nu >1} \simeq 0.2$, suggests that the second and higher interactions of the excited hadron inside the nucleus proceed with only slight energy losses.Comment: LaTeX file and 5 LaTeX files with figures, 11 pages altogether.
