Since the rules of the National Social Assistance (PNAS) and the Unified Social Assistance System (SUAS) in 2004/2005 the psychologist action as an essential professional teams in the services offered in this field. Althoug, there are indications of psychologists who worked on the assistence prior this time. This insertion had not systematized in the literature, not allowing the establishment of records of this linear trajectory. The objective of this paper is investigate the entrance and a psychologist working in social care services in Natal / RN , as well as the activities undertaken by them in the period 1972-2003 . This temporal boundary is justified because Natal initiate to have a psychologist from 1972 to 2003 was immediately prior to the landmarks of the 2004/2005 year. The research was divided into two stages: documentary and oral history. The first was through the consultation of 86 monographs of the Sector Documentation Social Service Department of the Federal University of Rio Grande do Norte , its intend identify what were the services that characterized the health care field and evidence of the presence of psychologists in these spaces. In the second stage, interviews with psychologists who worked 13 trailers to social assistance in order to investigate its performance, activities undertaken, the insertion process in the area, among other things were done. The material analysis was based on themes from a historical perspective. The results point to three major areas of integration of psychologists : in child exceptionality in which psychologists were linked to Brazilian Legion Social Assistance (LBA); the field of the minor through the State Foundation for the Well Being of Minors (center), and occupying positions of management and coordination in some welfare programs.

A conventional way to identify bridge frequencies is utilizing vibration data measured directly from the bridge. A drawback with this approach is that the deployment and maintenance of the vibration sensors are generally costly and time-consuming. One of the solutions is in a drive-by approach utilizing vehicle vibrations while the vehicle passes over the bridge. In this approach, however, the vehicle vibration includes the effect of road surface roughness, which makes it difficult to extract the bridge modal properties. This study aims to examine subtracting signals of two trailers towed by a vehicle to reduce the effect of road surface roughness. A simplified vehicle-bridge interaction model is used in the numerical simulation; the vehicle - trailer and bridge system are modeled as a coupled model. In addition, a laboratory experiment is carried out to verify results of the simulation and examine feasibility of the damage detection by the drive-by method.
