Abstract

The present study was aimed to determine the profile of sexual risk behavior of adolescents in conflict with the law, and analyze the influence of parents on such behavior, considering the level of support and supervision of their children perceive them and the frequency with which they communicate on issues related to sexual health care. 320 men (M = 16.33 years) belonging to a Community Diagnostic of Mexico. The results showed that adolescents have sexual risk profile, they have started their sexual debut from the thirteen years they have multiple sexual partners were evaluated, and they report different sexual practices, a high percentage of teenagers reported having had sex under the influence of alcohol and drugs. Over 20% reported some sexual health problem. Regarding the role of the parents was found to promote different preventive behaviors, depending on whether the father or mother, for example, they delay their sexual debut, greater frequency of condom use, is less frequent sex under the effects of alcohol and drugs. The results are discussed in terms of the importance of involving parents in the assessment of sexual behavior and sexual health programs generate in this population.

Abstract

The objective of the present work is to analyze the influence of the lightweight concrete block support on the physical and mechanical characteristics of the applied mortar. This work aims to understand how the physical and mechanical properties of the mortar are modified by the support. The methodology used consisted of conducting laboratory experimental tests to compare the behavior of mortar molded in standard moulds with the behavior of mortar applied to lightweight concrete block supports. Open porosity, bulk density, capillary water absorption, water vapor permeability and compressive strength were studied. These results have shown how the support influences the characteristics of the mortar, improving the understanding of the performance of the applied mortar. This study provides a global approach to the assessment of mortar characteristics, considering the analysis and comparison of mortar applied to the support and molded in the laboratory, according to current standards. Such understanding may contribute to the reassessment of the way mortars are produced, seeking to optimize their characteristics and compatibility with the support.
