The present study is a cutout made from a research master's thesis in the Social Sciences Graduate Program of the Universidade Federal de Uberlândia (PPGCS/UFU). Its overall objective is to understand the forms of sociability and social relations, in which are inserted male adolescents who conflict with the law and received deprivation of liberty as educational correctional measures in the Centro Socioeducativo de Uberlândia/MG -CSEUB. We intended to understand the representations and classifications that the surveyed individuals built to understand its social experiences and give it meaning. As well as to understand what the educational correctional measures means to them. Therefore, we used Marxism as a theoretical and methodological basis for the whole research process, including data analysis. Basis that is opposed to the naturalist and deterministic reality perspective. So, this research is mainly qualitative, answering to the specific aspects of a human being research, once we choose working with meanings, that is not displaced from surveyed individuals' reality. So, we start from a cutout in surveyed individuals' sociability in aspects of education, work, family and community. We intend to build an analysis that considered that the surveyed individuals' way of living and self-reproduction is inserted in the sociability proper of capitalism. In this attempt, first we made bibliographic research, looking for researchers and their productions dealing with this theme. In field research to understand the forms of sociability and social relations in surveyed individuals given meanings, a case study was carried out in CSEUB. So, chapter one is about fundamentals concepts for the understanding of this analysis, such as youth, sociability, work, Capital and Nation. In chapters two and three we intended to insert surveyed individuals in a macrosocial context, mainly regarding work and education aspects, and concerning globalization deepening and capital crisis context, with the labor flexibilization, productive restructuring and neoliberalism, and different educational trajectories for the individuals according to their social origin. Finally, in chapter four we pointed out clues to the understanding of criminalization process and penalty in which are inserted adolescents who conflict with the law, as well as CSEUB institution. As final results we understood that the researched adolescents and its social group has their sociability configured by Capital reproduction and maintenance structure. Therefore, we know that this research must go on, once it isn't exhausted and presents new questions and aspects to be under study.
