The project aimed to issue medical reports that attests the presence or absence of zoonosis in domestic animals. It was implemented for offline work, making it possible to generate a ZIP file to backup the stored data and restore the data from this backup file. The system manages the registry of medical clinics, veterinarians associated with one or more clinics, attending animals, types of biological samples, and pathogens under investigation. It allows to generate the medical report in .pdf and/or send it by e-mail to the clinic or the requesting doctor. It also allows us to generate periodic Excel reports (.xlsx) from all records in this period. It was built in PHP and uses AJAX to perform the main activities of dispatching reports asynchronously (without the need for page reload).

We often had to create reports of scientific publications from Brazilian researchers. In Brazil we have the Lattes curriculum system (http://buscatextual.cnpq.br/buscatextual), where researchers maintain their annual scientific publication data. Anyone can access the curricula individually, one at a time. But we often need to analyze the production data of several researchers at the same time, and so far it has been done manually, by opening each curriculum and copying each information, which took a lot of time.
Therefore, a system in php has been developed that accepts an arbitrary number of curricula downloaded in XML format from the Lattes system and generates several reports in Excel (.xlsx). Such system is publicly available at www.cienciaanimal.ufpa.br/lattes. It uses only the PHP session to store the submitted XML contents (does not permanently store the data) and the PHPExcel library (https://github.com/PHPOffice/PHPExcel) to generate production reports.

PHP program reporting bibliographic production in Excel

The goal was to read .csv files (containing personal finances data) into R, and presents graphics, tables and basic descriptive statistics to the user for decision-making. The descriptive statistics included Shapiro-Wilk test (to access univariate normality) as well as point estimation and confidence intervals for the mean and the median. The .csv file is exported from a free mobile app (MyExpenses by Michael Totschnig) that is a personal finance manager writen for Android. Following, the .csv is saved into the R app and processed for posterior presentation to the Shiny R package. Shiny is designed for integration between R and user-friendly WEB interface.

R Project - Personal Finances Reporting

This site (available in www.sindtifes.gov.br in pt-BR) was constructed using the Joomla Content Management System, that is writen on PHP. The project was to restructure the website that belongs to a federal trade union from Pará/Brazil. Some of the changes was: 1. The general appearance was adequated through a new template and custom CSS rules; 2. Reestruturing of the image and video galleries; 3. Implementation of the documents section using the component PhocaDownload; 4. Implementation of a system that permits new employers to submit membership request through the public site, by filling a form with personal data, using the component BreezingForms; 5. Reestructuring of the home page by adding modules for banners, pools, lattest news and social networks.

The objective was to provide dynamic data vizualization of a publically available dataset (from www.kaggle.com) by using (mainly) the R packages Shiny and lattice. So, the target was descriptive statistics. Shiny is designed for integration between the data analysis power of R and the user-friedly WEB interface. Lattice is designed for powerful multivariate plotting. The project output was the R program and a report contrasting dynamic versus statical data vizualization techniques, as well as describing the interpretation of the grafical results on the context of "Adult Census Income". The dataset comprised 32561 observations (rows) and 15 variables (columns).
