Geographic Information System (GIS) is a technology that deals with location to support better representations and decision making. It has a long tradition in several planning areas, such as urbanism, environment, riskiness, transportation, archeology or tourism. In academics context higher education has followed that evolution. Despite of their potentialities in education, GIS technologies at the elementary and secondary have been underused. Empowering graduates to learn with GIS and to manipulate spatial data can effectively facilitate the teaching of critical thinking. Likewise it has been recognized that GIS tools can be incorporated as an interdisciplinary pedagogical tool. Nevertheless more practical examples on how GIS tools can enhance teaching and learning process, namely to promote interdisciplinary approaches. The proposed paper presents some results obtained from the project “Each thing in its place: the science in time and space”. This project results from the effort of three professors of Geography, History and Natural Sciences in the context of Didactics of World Knowledge curricular unit to enhance interdisciplinarity through Geographic Information Technologies (GIT). Implemented during the last three years this action-research project developed the research practice using GIS to create an interdisciplinary attitude in the future primary education teachers. More than teaching GIS the authors were focused on teaching with GIS to create an integrated vision where spatial data representation linked the space, the time and natural sciences. Accumulated experience reveals that those technologies can motivate students to learn and facilitating teacher’s interdisciplinary work.

Este trabalho é um estudo sobre o sistema de informação Tribunal Colectivo dos Géneros Alimentícios, como nasceu e como se desenvolveu, através do estudo orgânico-funcional, análise da produção e tramitação documental, desde a sua criação (1930) até à sua extinção (1976), através da aplicação do método de investigação quadripolar. Este método vai desenrolar-se mediante três actividades, cujo exercício se integra numa abordagem sistémica: a) Estudo da natureza da instituição a partir da análise dos seus fins, dos seus órgãos, das suas funções e da sua prática administrativa, tendo em conta tanto a evolução destes elementos ao longo do tempo como as relações que se estabelecem entre eles, através da análise de leis orgânicas e outros diplomas legais. b) Identificação e delimitação das séries documentais a partir da análise dos modos de produção documental, as características externas e internas destes tipos de documentos e as operações de conservação, descrição e organização arquivística. c) Apresentação do quadro de classificação: estrutura hierárquica e lógica que reflicta as funções deste sistema de informação. Pretende-se dar resposta às seguintes questões: 1- como classificar arquivisticamente a documentação acumulada no Arquivo Tribunal Colectivo dos Géneros Alimentícios? 2- Classificar arquivisticamente os processos de infracções/crimes do Tribunal de Recurso da Intendência-Geral da Segurança Pública e os processos de infracções/crimes até 1936 no sistema Tribunal Colectivo dos Géneros Alimentícios. 3- A produção e o circuito documental do Tribunal Colectivo dos Géneros Alimentícios são semelhantes à produção documental dos tribunais de jurisdição ordinária? 4- Quais a(s) especificidade(s) a nível processual e de tipologias documentais. ABSTRACT: This thesis is a study on the information system of the Tribunal Colectivo dos Géneros Alimentícios: how it started and how it was developed, and we do so proceding with the study of the organizational system, of the channeling of the proceedings and documents, since its creation (1930) until its ending (1976), using the quadripolar research method. This method will develop into three different steps, following a systemic approach and using the Quadripolar Method: a) A study of the nature of the institution supported by the analysis of its purposes, its organs, its functions and its administrative practices, bearing in mind the evolution of these elements throughout time and the connections that are established between them, with the support of some organic laws and other legal diplomas. b) Identification and caracterization of the document series; the method that it will be used will include an analysis of the process of document production, and also of both the internal and external characteristics of that type of documents and the archival conservation, description and organization. c) Demonstration of the classification board: hierarchic structure and the logic that is behind the institution of this documental base. This work intends to answer the following questions: 1. How to classify archival documentation accumulated in the Tribunal Colectivo dos Géneros Alimentícios? 2. How to classify the offense/crimes processes at the Tribunal de Recurso at Intendência-Geral da Segurança Pública and the offense/crimes processes until 1936 at Tribunal Colectivo dos Géneros Alimentícios? 3. Are the circuit and the document production of the Tribunal Colectivo dos Géneros Alimentícios similar to the production of documents in regular jurisdiction courts? 4. What are the specific level procedural and documentary types?

Matrix factorization (MF) has evolved as one of the better practice to handle sparse data in field of recommender systems. Funk singular value decomposition (SVD) is a variant of MF that exists as state-of-the-art method that enabled winning the Netflix prize competition. The method is widely used with modifications in present day research in field of recommender systems. With the potential of data points to grow at very high velocity, it is prudent to devise newer methods that can handle such data accurately as well as efficiently than Funk-SVD in the context of recommender system. In view of the growing data points, I propose a latent factor model that caters to both accuracy and efficiency by reducing the number of latent features of either users or items making it less complex than Funk-SVD, where latent features of both users and items are equal and often larger. A comprehensive empirical evaluation of accuracy on two publicly available, amazon and ml-100 k datasets reveals the comparable accuracy and lesser complexity of proposed methods than Funk-SVD.

Declarative techniques such as Constraint Programming can be very effective in modeling and assisting management decisions. We present a method for managing university classrooms which extends the previous design of a Constraint-Informed Information System to generate the timetables while dealing with spatial resource optimization issues. We seek to maximize space utilization along two dimensions: classroom use and occupancy rates. While we want to maximize the room use rate, we still need to satisfy the soft constraints which model students’ and lecturers’ preferences. We present a constraint logic programming-based local search method which relies on an evaluation function that combines room utilization and timetable soft preferences. Based on this, we developed a tool which we applied to the improvement of classroom allocation in a University. Comparing the results to the current timetables obtained without optimizing space utilization, the initial versions of our tool manages to reach a 30% improvement in space utilization, while preserving the quality of the timetable, both for students and lecturers.

The research activities involved the application of the Geomatic techniques in the Cultural Heritage field, following the development of two themes: Firstly, the application of high precision surveying techniques for the restoration and interpretation of relevant monuments and archaeological finds. The main case regards the activities for the generation of a high-fidelity 3D model of the Fountain of Neptune in Bologna. In this work, aimed to the restoration of the manufacture, both the geometrical and radiometrical aspects were crucial. The final product was the base of a 3D information system representing a shared tool where the different figures involved in the restoration activities shared their contribution in a multidisciplinary approach. Secondly, the arrangement of 3D databases for a Building Information Modeling (BIM) approach, in a process which involves the generation and management of digital representations of physical and functional characteristics of historical buildings, towards a so-called Historical Building Information Model (HBIM). A first application was conducted for the San Michele in Acerboli’s church in Santarcangelo di Romagna. The survey was performed by the integration of the classical and modern Geomatic techniques and the point cloud representing the church was used for the development of a HBIM model, where the relevant information connected to the building could be stored and georeferenced. A second application regards the domus of Obellio Firmo in Pompeii, surveyed by the integration of the classical and modern Geomatic techniques. An historical analysis permitted the definitions of phases and the organization of a database of materials and constructive elements. The goal is the obtaining of a federate model able to manage the different aspects: documental, analytic and reconstructive ones.

To analyze the prevalence of cervical cytopathological results for the screening of cervical cancer with regard to women's age and time since the last examination in Maceió and Rio de Janeiro, Brazil, among those assisted by the Brazilian Unified Health System. Cervical cytopathological results available in the Information System of Cervical Cancer Screening for the year 2011 were analyzed, corresponding to 206,550 for Rio de Janeiro and 45,243 for Maceió. In Rio de Janeiro, examination at one and two year intervals predominated, while in Maceió examination at one and three year intervals had a higher predominance. Women who underwent cervical smear screening in Maceió were older than those in Rio de Janeiro. The prevalence of invasive squamous cell carcinoma was similar for the two cities, but all the other results presented a higher prevalence in Rio de Janeiro: ASCUS (PR=5.32; 95%CI 4.66-6.07); ASCH (PR=4.27; 95%CI 3.15-5.78); atypical glandular cells (PR=10.02; 95%CI 5.66-17.76); low-grade squamous intraepithelial lesions (PR=6.10; 95%CI 5.27-7.07); high-grade squamous intraepithelial lesions (PR=8.90; 95%CI 6.50-12.18) and adenocarcinoma (PR=3.00; 95%CI 1.21-7.44). The rate of unsatisfactory cervical samples was two times higher in Maceió and that of rejected samples for analysis was five times higher in Maceió when compared to Rio de Janeiro. The prevalence rates of altered cervical cytopathological results was significantly higher in Rio de Janeiro than in Maceió. There is no objective information that may justify this difference. One hypothesis is that there may be a difference in the diagnostic performance of the cervical cancer screening, which could be related to the quality of the Pap smear. Thus, these findings suggest that it would be necessary to perform this evaluation at national level, with emphasis on the performance of cervical cancer screening in order to improve the effectiveness of cervical cancer control.

In Brazil, malaria remains a disease of major epidemiological importance because of the high number of cases in the Amazonian Region. Plasmodium spp infections during pregnancy are a significant public health problem with substantial risks for the pregnant woman, the foetus and the newborn child. In Brazil, the control of malaria during pregnancy is primarily achieved by prompt and effective treatment of the acute episodes. Thus, to assure rapid diagnosis and treatment for pregnant women with malaria, one of the recommended strategy for low transmission areas by World Health Organization and as part of a strategy by the Ministry of Health, the National Malaria Control Program has focused on integrative measures with woman and reproductive health. Here, we discuss the approach for the prevention and management of malaria during pregnancy in Brazil over the last 10 years (2003-2012) using morbidity data from Malaria Health Information System. Improving the efficiency and quality of healthcare and education and the consolidation of prevention programmes will be challenges in the control of malaria during pregnancy in the next decade.

Currently, owing to the occurrence of environmental problems, along with the need of environmental preservation, both the territory management of Hydrographic Basin and the conservation of natural resources have proven to have remarkable importance. Thus, the mean goal of the research is to raise and scrutinize social-economic and technologic data from the Mogi Guaçu River Hydrographic Basin (São Paulo, Brazil). The aim is to group municipalities with similar characteristics regarding the collected data, which may direct joint actions in the Hydrographic Basin Management. There were used both the methods of factorial analysis and automatic hierarchical classifications. Additionally, there is going to be applied a Geographical Information System to represent the outcomes of the methods aforementioned, through the evolvement of a geo-referenced database, which will allow the obtainment of information categorically distributed including theme maps of interest. The main characteristics adopted to group the municipalities were: agricultural area, sugar cane production, small farms, animal production, number of agriculture machinery and equipments and agricultural income. The methodology adopted in the Mogi Guaçu River Hydrographic Basin will be analyzed vis-à-vis its appropriateness on basin management, as well as the possibility of assisting the studies on behalf of the São Paulo Hydrographic Basin groups, to regional development.

OBJETIVO: Analisar o risco relativo para Aids na população de homens que fazem sexo com homens em relação à população heterossexual masculina. MÉTODOS: Foram utilizadas estimativas sobre a proporção de homens que fazem sexo com homens no Brasil e dados de Aids do Sistema Nacionald e Agravos de Notificação. Foram calculadas estimativas para o risco relativo (RR) para Aids desta população em relação à população heterossexual masculina do Brasil; cidade e estado de São Paulo; e cidade e estado do Rio de Janeiro, para o período de 1996 a 2003. As trajetórias do RR neste período também foram analisadas. RESULTADOS: As estimativas do RR declinaram, mostrando tendência de estabilização: de 34,3 para 19,3 no País como um todo e entre 32,1 e 6,3 nos locais analisados. Para o País em 2003, o RR dos bissexuais masculinos em relação à população heterossexual masculina era 16. O RR para homossexuais exclusivos teve trajetória decrescente em todos os locais analisados, mas não para os bissexuais. CONCLUSÕES: O risco relativo para homens que fazem sexo com homens foi mais elevado em relação aos heterossexuais, em todos os locais. Esse resultado indica alta e persistente vulnerabilidade dessa população.
