To understand the practices and the experimental formation of the psychopedagogy of abnormal childhood in Colombia, carried out in the San Jose Juvenile Correctional Facility and Work School, Colombia, between 1914 and 1947. Methods and materials: qualitative study, of a historical-hermeneutic approach, using documentary research, and file heuristics of document heritage and institutional historiography within the study period. Conclusions The emergence of a new special education regime (medical and psychopedagogical) established an important change in the model of punishing reformatory to pedagogical intervention, influenced by crossing scientific doctrines of the late nineteenth and early twentieth centuries, such as the rule of normal and pathological, the degeneration theory and eugenics, for perfecting a modern subject who can be useful to itself and to society. © 2009 University Association for Research in Fundamental Psychopathology.

Objective To compare the perceptions about HIV/AIDS of homosexual and bisexual Colombian males who live in the Colombian "Eje Cafetero" (Coffee Zone) and of those who migrated to Spain, in order to investigate whether those perceptions have an influence on the social vulnerability of the groups involved, which is determined by aspects such as inequalities that may emerge from ignorance about cultural and sexual diversity of the people who are undergoing a migratory process. Methods This research has a transnational character and was carried out by way of in-depth interviews of adult males living in the autonomous communities of Madrid, Valencia, Cataluña and Andalucía in Spain, and in the departments of Caldas, Quindío, Risaralda and Valle del Cauca in Colombia between 2011 and 2013. In total, 87 interviews were performed in both countries. Conclusion The relationship between migration and sexuality must be contemplated from a comprehensive viewpoint that enriches understanding both of the society of origin as well as of the welcoming country through a consideration of social and cultural aspects. Any health promotion and prevention program expecting to have an influence on social aspects must take into account people’s particularities in order to avoid generalizations and their exploitation, recognizing them and making them visible as individuals with full rights who express opinions, speak and participatevisible as whole right individuals, who express opinions, speakand participate. © 2016, Universidad Nacional de Colombia.

This document describes the architecture and technology of an IPTV network and, present the direct causes that generate considerable in the delay time of channel switching to user perception. Also some techniques that have been developed to mitigate the delay in the zapping are listed. This work propose developing an ARIMA time series model to model and predict the behaviour of the rating in the channels with more audience on an IPTV platform. The validation of the proposed model is performed from real data of the rating provided by UNE Telecommunications. The results show a low percentage of error in the prediction of the rating for one week and mitigation of channel zapping delay in 68% approximately.

The aim of this research was to determine the effect of formative pruning of olive trees in the quantity of nitrogen fixing fungi colonies and their activity in the rhizosphere of productive trees established in Sutamarchán, Boyacá. Trees in productive stage (<4 years) old were selected and a complete randomized design with two treatments (pruning and no pruning) and three repetitions was used. Rhizosphere soil samples were carried out to determine the population of diazotrophs microorganisms and concentrations of NH4, NO3, CO, Fe y Mg; leaves were sampled to determine elements concentration. The statistical analysis concluded that pruning olive trees tended to increase the acidity in soil. N concentrations in soil and leaves were significantly lowest than the no-pruning trees. However, nitrogen fixing microorganisms populations were higher but with less efficiency, possibly related with the free-living fixation. The concentrations of Fe and Mg in soil, suggest a constant nitrogenase activity, but N is immobilized possibly by the microbial metabolism, lowering the possibility of being absorbed by the trees; Ca levels restricts the N nutrition. To take into account in future experiments, it's suggested to identify microorganisms populations, and measure acetylene reducing activity and the mineralization rate.

The effect of exercise on brain function has been reported in several studies over the years, but the mechanism that could explain this effect is not always consistent, and instead, there have proposed several different mechanisms. This review shows in its initial part a description of the effects of exercise on brain structure and function at different levels, from the molecular and epigenetic level to cognitive level. Then, the basic features of motor control and the effects of training, learning and motor memory encoding are described. Finally, we discuss on the possibility that the phenomena of creation of new neurons and synapses may explain the effects of exercise and motor activity on cognition, but probably in the form of induction of this plasticity is given by different molecular and cellular routes.

Motion sickness or kinetosis is the result of the abnormal neural output originated by visual, proprioceptive and vestibular mismatch, which reverses once the dysfunctional sensory information becomes coherent. The space adaptation syndrome or space sickness relates to motion sickness; it is considered to be due to yaw, pith, and roll coordinates mismatch. Several behavioural and pharmacological measures have been proposed to control these vestibular-associated movement disorders with no success. Galvanic vestibular stimulation has the potential of up-regulating disturbed sensory-motor mismatch originated by kinetosis and space sickness by modulating the GABA-related ion channels neural transmission in the inner ear. It improves the signal-to-noise ratio of the afferent proprioceptive volleys, which would ultimately modulate the motor output restoring the disordered gait, balance and human locomotion due to kinetosis, as well as the spatial disorientation generated by gravity transition.

To improve the quality of people life and to reduce the risk of vulnerability of these, the engineering has some challenges. The engineering learning and engineering teaching should to create and to recreate them, that which is possible with the understanding and the approach to the reality or situation that the engineering students want to transform with students of other disciplines. An example of these initiatives is the The Center of Education for the Development (CED). In this center professors and students of all the academic programs converge which I lower the pedagogic focus of education for the development. They have to design and implement practical in social responsibility as Engineer's project to the Neighborhood with Ingenieros sin Fronteras. These projects are learning spaces where the students have the possibility in classroom and marginal communities to apply knowledge among other disciplines and to acquire new knowledge, abilities and vital social and talkative competitions for their professional exercise and interaction with the other ones.

This paper presents our work-in-progress on the study of a practical variant of the vehicle routing problem in which customers are to be serviced within given service time windows. In comparison with time windows models traditionally studied in the VRP literature in which hard time windows are to be respected when servicing a customer, our problem allows the violation of such time windows by considering fuzzy time windows. A hybrid genetic algorithm with fuzzy membership functions is proposed to solve the multi-objective problem of minimizing total travel distance of vehicles and maximizing customer service level. Preliminary results on a set of experiments carried out using well-known instances from literature are also presented. © 2011 IEEE.

In the present study we used the instrument developed by Davidson (2006) to measure logistics indicators in logistics management of two types of operations in two different disasters in Colombia. Key indicators in humanitarian logistics are used to compare performances of local aid organizations in the two operations. Results indicate a great difference between the organizations performance according to the type of disaster. In a forced-migration operation, indicators are lower than in a flooding operation; difficulties to reach the site due to actions of illegal armed groups hampered the access to the affected population. The key performance indicator framework can be used further to assess the performance of private and government organizations which carry out humanitarian operations in Colombia. © IFAC.
