A major obstacle to processing images of the ocean floor comes from the absorption and scattering effects of the light in the aquatic environment. Due to the absorption of the natural light, underwater vehicles often require artificial light sources attached to them to provide the adequate illumination. Unfortunately, these flashlights tend to illuminate the scene in a nonuniform fashion, and, as the vehicle moves, induce shadows in the scene. For this reason, the first step towards application of standard computer vision techniques to underwater imaging requires dealing first with these lighting problems. This paper analyses and compares existing methodologies to deal with low-contrast, nonuniform illumination in underwater image sequences. The reviewed techniques include: (i) study of the illumination-reflectance model, (ii) local histogram equalization, (iii) homomorphic filtering, and, (iv) subtraction of the illumination field. Several experiments on real data have been conducted to compare the different approaches

A clinical psychotherapy needs to turn its gaze to the current demands, and update its practice in empirical studies. The objective of this research is to ascertain the sociodemographic and clinical characteristics of children treated in psychotherapy by learning problems. We conducted a retrospective documentary study with records of 2106 children treated between 1979 and 2007 in two outpatient psychological care of the city of Porto Alegre, southern Brazil. The results showed that demand for Learning Problems is the fourth largest cause of psychotherapeutic care. There was no statistically significant difference regarding gender. Children with learning problems come to psychotherapy more frequently in the early stages of elementary school, around 7 years old. Increased demand for psychotherapy of children with learning problems takes place in May. Perhaps, learning difficulties can be understood simultaneously as a symptom global, in which other aspects, besides the uniqueness of the subject are involved. We conclude that individual and social aspects involved in Learning Problems may be useful in the clinical management of these children by professionals who are dedicated to meeting this particular clientele. One must be aware of ongoing partnership which should be placed between psychologist and pedagogue. Both professionals, education and health, account for components of the child to know

The physical, psychological and sexual violence among the couples of adolescents and young adults that are not married neither cohabiting (well-known generally as “dating violence”), has been object of a vast number of investigations in the last two decades that show a high prevalence inside the adolescent and juvenile population. The objective of this work was to carry out an analysis of the literature in connection with the prevalence, risk factors and difficulties associated with this partner violence type. This analysis allowed to elaborate an outline of the factors that could favor the acts of violence, including the previous experiences of victimization inside and outside the family, the acceptance of the violence toward the couple, and the relationship with pairs that have exercised this form of violence.

Este estudio explora el estado actual y el potencial competitivo de las exportaciones agrícolas colombianas a los mercados de Estados Unidos y la Unión Eurpea. Los mercados de estos paises industrializados se constituyen en los más importantes para Colombia, pero al mismo tiempo tienen varias restricciones en el sector agrícola. Este estudio mostrará que la competitividad no es solamente una función de los impedimentos locales o internacionales tales como la pobreza institucional, la baja capacidad tecnológica, la disponibilidad de capital, capital humano y mano de obra, sino también de impedimentos externos como el acceso a los mercados. Por lo tanto, éste es un importante objetivo del presente estudio con el objeto de proyectar posibles escenarios para el comercio colombiano, a fin de investigar la eliminación de estas restricciones. En la parte empírica se enfatizará en los impactos de las restricciones externas en el sentido de un estudio econométrico, sin embargo, la influencia de las restricciones internas será discutida como tal.

In this work we analyze the reforms carried out by the Mexican state in the nineties of the 20th century, in the items concerning the policies of housing and urban land, based on an exhaustive review of the main actions, programs and changes in the legal and institutional frame that applies for each of these fields. The nineties represent a "breaking point" in the way the State considers the satisfaction of the right to the housing and attends the offer of urbanized land for a tidy and sustainable urban development. In this period of time, the approach of direct intervention in developing and financing housing and creation of land reserves has changed into another one, ruled by the logic of the market. The balance to the first decade of the 21st century is ambiguous, as neither the housing policy has solved the housing shortage for low-income population, nor the land policy has eliminated the illegal urban growth.

Este estudio analiza el tipo de errores que los estudiantes españoles del primer año de magisterio cometen al leer y entender diferentes artículos de revistas y periódicos en inglés. Los resúmenes hechos por los estudiantes después de leer los textos son un buen instrumento para medir el tipo de problemas que ellos tienen. Los errores más frecuentes son los que tienen que ver con la gramática y con la cohesión del texto, más que con el léxico del artículo.
