DOCUMENTARY RESCUE OF POPULAR TRADITIONS OF THE CENTRAL AREA CANTONS HEREDIA PROVINCE

This paper presents the results of documentary rescue demonstrations performed in different counties present in the central area of the province of Heredia.This idea was enhanced thanks to the Organization of the United Nations Educational, Scientific and Cultural Organization (UNESCO) has provided the rescue and preservation of folk traditions, both tangible and intangible, throughout the world.Coupled with this, the Ministry of Education under the direction of Professor Manuel Antonio Bolaños, launched in the administration of La Espriella Pacheco (2002-2006) the development of an educational project aimed at rescuing the popular traditions of the province of Heredia, which under the title"Draft Heredianidad" became one of the main inspiring to be translated into a multimedia all information collected in the process of this research.The final graduation consisted of three major axes: the memory, the media containing all the information collected and a database in which (the) user (s) and to describe the bibliographic production on the subject of popular traditions Heredia has occurred, would help to physically locate these publications.To achieve the objectives we proceeded to conduct visits to public libraries and municipalities in the province as well as interviews with different artistic personalities of the cantons heredianos, thereby gained access to various legends, anecdotes, stories, songs, music and history of the province of Heredia.

Elimination of urine in response to water intake is consistent in well-hydrated individuals

A simple method has been recently proposed to assess acute hydration status in humans; however, several questions remain regarding its reliability, validity, and practicality. Objective: Establish reliability of a simple method to assess euhydration, that is, to analyze whether this method can be used as a consistent indicator of a person´s hydration status. In addition, the study sought to assess the effect exercise has on urine volume when euhydration is maintained and a standardized volume of water is ingested. Methods: Five healthy physically active men and five healthy physically active women, 22.5 ± 2.3 years of age (mean ± standard deviation) reported to the laboratory after fasting for 10 hours or more on three occasions, each one week apart. During the two identical resting euhydration conditions (EuA and EuB), participants remained seated for 45 minutes. During the exercise condition (EuExer), participants exercised intermittently in an environmental chamber (average temperature and relative humidity = 32 ± 3°C and 65 ± 7%, respectively) for a period of 45 minutes and drank water to offset loss due to sweating. The order of treatments was randomized. Upon finishing the treatment period, they ingested a volume of water equivalent to 1.43% body mass (BM) within 30 minutes. Urine was collected and measured henceforth every 30 minutes for 3 hours. Results: Urine volume eliminated during EuExer (1205 ± 399.5 ml) was not different from EuB (1072.2±413.1 ml) or EuA (1068 ± 382.87 ml) (p-value = 0.44). Both resting conditions were practically identical (p-value = 0.98) and presented a strong intraclass correlation (r = 0.849, p-value = 0.001). Conclusions: This method, besides simple, proved to be consistent in all conditions; therefore, it can be used with the certainty that measurements are valid and reliable.

Efectos de un programa de aquaerobic sobre la composición corporal, en las mujeres activas de mediana edad

Objetivo: Describir y analizar las modificaciones en la composición corporal, en las mujeres de mediana edad, después de realizar un programa de actividad física, basado en el aquaerobic, y un posterior periodo de desentrenamiento. Material y método: El grupo analizado estuvo integrado por diecisiete mujeres de Arroyo de San Serván (Badajoz), físicamente activas (habían realizado programas de gimnasia de mantenimiento, con una frecuencia de una a tres sesiones semanales, durante los últimos tres meses), con una edad media de 53,6 ± 9,1 años. El programa se desarrolló con sesiones de sesenta minutos durante cinco días a la semana, por seis semanas, con un periodo de desentrenamiento de cuatro semanas. Se realizaron tres evaluaciones antropométricas: al iniciar el programa, al finalizar el mismo, tras el periodo de desentrenamiento. En cada medición, se determinaban la talla y el peso, seis pliegues cutáneos, cuatro perímetros corporales y tres diámetros óseos. El porcentaje de grasa fue obtenido a través de los datos arrojados en cuatro pliegues cutáneos (tricipital, subescapular, suprailíaco y abdominal) mediante la fórmula de Yuhasz, modificada por Faulkner (1968). Por su parte, el porcentaje muscular fue calculado, a partir del porcentaje de la masa total, menos el porcentaje óseo (Rocha, 1975), el porcentaje graso (Faulkner, 1968) y el porcentaje residual, a través de la ecuación de Wurch (Esparza, 1993), de los sujetos medidos, según la propuesta básica de Matiegka (modelo de los cuatro componentes). Resultados: después de realizar el programa, se observó un aumento significativo en el porcentaje muscular: 32.69 ± 2.69% vs. 33.44 ± 2.89% (p < 0.05), en el peso muscular: 23.45 ± 3.53 kg vs. 24.02 ± 3.33 kg (p <0.05), y un descenso significativo del componente graso reflejado, mediante el sumatorio de pliegues cutáneos: 193.66 ± 25.54 mm vs. 188.38 ± 25.67 mm (P <0,05), más específicamente, en el pliegue suprailíaco, 30.47 ± 8.49 mm vs. 28.00 ± 8.78 mm (p <0,05) Estas tendencias se mantuvieron durante el periodo de desentrenamiento, en el porcentaje muscular: 33.44 ± 2.89% vs. 34,25 ± 3,04% (p<0,01 con respecto a la inicial), en el peso muscular: 24.02 ± 3.33 kg vs 24,74 ± 3,64kg (p<0,01 con respecto a la inicial), el sumatorio de pliegues cutáneos: 188.38 ± 25.67 mm vs 183,41 ± 26,65 mm (p<0,05 con respecto a la inicial). Conclusiones: La participación en programas de aquaerobics de corta duración bajo las condiciones de este estudio provoca descensos del componente graso y aumentos significativos en el componente muscular, en las mujeres activas de mediana edad.

Medición y predicción de la radiación solar global ultravioleta (0.295-0.385 μm) en condiciones de cielos claros y sin nubes (ING)

Values of ultraviolet global solar radiation were measured with an ultraviolet radiometer and also predicted with an atmospheric spectral model. The values obtained with the atmospheric spectral model, which is physically based, were analyzed and compared with the experimental values measured in situ. The measurements were performed for different zenith angles under clear skies conditions in Heredia, Costa Rica. The necessary input data include latitude, altitude, surface albedo, Earth-Sun distance, as well as atmospheric characteristics: atmospheric turbidity, precipitable water and atmospheric ozone. The comparisons between the measured and predicted values gave satisfactory results.
