This study focuses on thoroughly examining how the geometric characteristics of rural roads in Peru impact safety, using the Highway Safety Manual (HSM) as the primary reference point. By adjusting the predictive HSM model to fit specific conditions, the most significant variables in anticipating road incidents were identified. Out of the 14 considered variables, three emerge as the most relevant in accident prediction. The presence of rumble strips, the Hazard Index in sections with obstacles and barriers account for 47.74% of relevance, while variables related to horizontal curves, such as length and radius, contribute with 18.35% importance in this predictive calculation. This study emphasizes the need to expand the database with information from other roads sharing similar characteristics. This would not only improve the accuracy of the calculation but also confirm the priority of th...

Lepidium meyenii Walpers (maca) is a Peruvian species cultivated in the high Andean region (ca. 4000 m.a.s.l.), highly praised for the nutritional properties of its hypocotyl. The benefits to human health and their relationship with the hypocotyl have been well investigated. However, few studies have addressed the factors affecting field crop performance and the improvement of agronomic practices. Here we evaluate the effect of soil properties (humidity, temperature, and fertility) and sowing method (ridge-furrow system and flat planting) on the biological performance of five seed accessions of maca in 6 experimental plots along an altitudinal gradient (3554–4442 m.a.s.l.). Plots located at both the lowest and highest altitudes had lower plant survival, vegetative growth, and hypocotyl size. Most of the differences among plots could be attributed to the acidity and the concentration of...

The purpose of this study was to analize how a group of Education Faculty Students have their own social representations on working children, particulary how they conceive a working child, why a child works and about his or her family, but also how as future educators they will have a good management as social workers and they will succeed to establish a positive relationship with working children. The survey- a semistructured questionnairewas applied to 28 female students of the faculty of education and the results showed us the prevalence of the protectionist paradigm in relation to working children, but also a lack of a co-protagonism approach at all.
