Monitoramento por dgps e análise dos processos erosivos da linha de costa na praia de Pirangi do Norte - Parnamirim / RN

Through out the course of a steady increase in search and recovery of space in the coastal zone, there is also an expanding concern about the erosion processes of this area. The main problem in coastal areas is that urbanization occurs in a disorderly fashion and unsustainable, further aggravating the problems of coastal dynamics. The study area of this work is located on the southern coast of Pirangi do Norte beach to about 20km south of Natal, capital of Rio Grande do Norte in the Parnamirim City. This area has the length of approximately 1km, divided into three sections (Western, Central and Eastern) with a morphology consisting of a tableland at the top, sea cliffs in the West and Central parts and sand dunes in the Eastern section, both vegetated, and a coastal plain on the inferior part associated with the presence of beach rocks. This study aimed to analyze the erosion processes operating in the excerpt of Pirangi do Norte beach and assess the feasibility of their monitoring making use of DGPS (Global Positioning System Differential mode). During the work it was carried out a physical description of the area through photo-interpretation and site survey after measurement of the shoreline in the period between November 2004 and November 2009 and beach profiles between August 2005 and July 2006. The analysis of the results of the annual surveys showed the occurrence of variations of the shoreline along the stretch traveled. Sites are identified in advancement coast from the sea and it was verified in loco the presence of erosion with deposition of materials on the lower part of the coastal bluff, the former position of the shoreline, showing a false notion of advancing it. This leads to the conclusion that the data collected in a survey of the shoreline should always be accompanied by photographic records of the local area and with the highest rate of erosion, thus avoiding the mistake of treating the deposit materials as evidence of progress coast. At the end of the study, after a review of various works to mitigate the erosion in the coastal zone, it is recommended to the area of study the adoption of an artificial feeding of the beach, aiming the minimization of the erosive effects of the tides. Moreover, it is suggested that even the continuity of monitoring, maintenance of existing vegetation and control of the occupation on the edge of sea cliffs

A produção do gênero monografia em discursos de professores e alunos do curso de letras

A current worry in the teaching process at the university these days is text production process and genres produced there, especially those kind of writing that is concerned to course conclusion such as monograph, dissertation and thesis. From this perspective and considering our aims at understanding discursive process involved in the production of monograph genre at the university we want to analyze teachers and students discourses about the productive process of monograph in Letras Course, considering the guide, writing and specific aspects of that genre. To get the aims, we took as background theory the studies by Bakhtin linked to Utterance Linguistics with foundation concepts in Discourse Text Analysis by Adam (2010), and finally the studies developed about text production at college. This way, this work is based on a qualitative research and in data ethnographic procedures, they are: the observation in locus, as well as the application of questionnaires with opened questions to ten students and six teachers from Letras Course. The discourse analysis from the subjects reveal us that: i) the monograph production and the guidance are form of act by language, that need take into account in its development: students free chose as a principle in writing monograph, as well as a wide involvement between the teacher and the student in a sense to turn the writing better, among other aspects; (ii) there is a need to articulate monograph project and the text produced, considering that the guide process comes from a project written before; (iii) there are a number of role to discourses by teachers and students to the function of student and guide teacher, in a way that both can see the same assumptions in teachers and students discourses; (iv) teacher s and students discourses show that they assume the utterance responsibilities by the content of utterances proposed, they also show the voice from methodology guidebooks to monograph texts. So, we conclude that this research has some contributions to teach writing production at the university, especially to monograph in the ending of the courses. It can also be helpful in developing research in this area, mainly at the question about guide final works at college
