Estimating the average length of hospitalization due to pneumonia: a fuzzy approach

Exposure to air pollutants is associated with hospitalizations due to pneumonia in children. We hypothesized the length of hospitalization due to pneumonia may be dependent on air pollutant concentrations. Therefore, we built a computational model using fuzzy logic tools to predict the mean time of hospitalization due to pneumonia in children living in São José dos Campos, SP, Brazil. The model was built with four inputs related to pollutant concentrations and effective temperature, and the output was related to the mean length of hospitalization. Each input had two membership functions and the output had four membership functions, generating 16 rules. The model was validated against real data, and a receiver operating characteristic (ROC) curve was constructed to evaluate model performance. The values predicted by the model were significantly correlated with real data. Sulfur dioxide and particulate matter significantly predicted the mean length of hospitalization in lags 0, 1, and 2. This model can contribute to the care provided to children with pneumonia.

Analysis of hybrid waste-to-energy for medium-sized cities

Urban centers have a huge demand for electricity and the growing problem of the solid waste management generated by their population, a relevant social and administrative problem. The correct disposal of the municipal solid waste (MSW) generated in cities is one of the most complex engineering problems that involves logistics, safety, environmental and energetic aspects for its adequate management. Due to a national policy of solid wastes recently promulgated, Brazilian cities are evaluating the technical and economic feasibility of incinerating the non-recyclable waste. São José dos Campos, a São Paulo State industrialized city, is considering the composting of organic waste for biogas production and mass incineration of non-recyclable waste. This paper presents a waste-to-energy system based on the integration of gas turbines to a MSW incinerator for producing thermal and electric energy as an alternative solution for the solid waste disposal in São José dos Campos, SP. A technical and economic feasibility study for the hybrid combined cycle plant is presented and revealed to be attractive when carbon credit and waste tax are included in the project income. © 2013 Elsevier Ltd.

Vicentina Aranha de sanatório a parque: histórias e mudanças

This assignment intents to analyze the recover and the research of the cultural legacy identity of Vicentina Aranha Sanatorium to the inhabitants of the city of São José dos Campos-SP. That initiative becomes present through the importancy of the sanatorium to the public health of Vale do Paraíba in the decades between 30 and 70, of the 20th century. Nowadays this place refuges a park, presenting a reexamination of its space, with the possibility of the leisure practice, entertaining and tourism. The Vicentina Aranha Sanatorium Park presents itself conserving a landscape that is able of being inserted in a continuum past-present resignifying ways of appropriation and use. The word patrimony has many meanings and it‟s commonly associated to the set of goods that someone, the society or an entity owns. Transporting in a determinate territory, the patrimony starts to be a set of goods that are in its limits of administrative competency. (BARRETO, 2000). More than this, the cultural-historical patrimony guard a relation of belonging between it and the entity that has it. The Vicentina Aranha Sanatorium was inaugurated in 1924, with the project of the architect, Ramos de Azevedo, constituting an architectural ensemble placed under governmental trust as a historical and cultural patrimony of the state in 2001. It has a grove with centenary vegetal species like: MOGNO, PEROBA ROSA, JEQUITIBÁ and JACARANDA, constituting also a natural patrimony important for the city. There are projects like “Leitura no Bosque” and it‟s visited by the local population. Today the city seeks a new identity for that place transforming it in the center of industrial and technologic study

Ability of different methods to fill retrograde cavities with MTA.

The Mineral Trioxide Aggregate (MTA) has excellent biological property. However, its consistency makes it difficult to be inserted into retrograde cavities. Objective:To evaluate the ability of different methods to fill retrograde cavities with MTA. Material and methods: Root canals of thirty single-rooted resin teeth were prepared and filled. After the cut of 3 mm short of apical third, retrograde cavities with 3 mm deep were prepared using an ultrasound device and retrotips (CVD, São José dos Campos, SP, Brazil). The retrograde preparation was evaluate by using an operative microscope (D.F. Vasconcellos, São Paulo, SP, Brazil). The teeth were randomly divided into three groups (n = 10), according to the method: 1) condenser (Trinity, São Paulo, SP, Brazil); 2) MTA applicator (Angelus, Londrina, Brazil) + condenser; 3) condenser associated with ultrasound (CVD, São José dos Campos, SP, Brazil). After the filling of retrograde cavities with white MTA (Angelus, Londrina, Brazil), teeth were radiographed using a digital system (Kodak RVG 6000, Rochester, NY, USA). The images were analyzed by UTHSCSA Image Tool 3.0 software. The percentage of filling was calculated by the proportion between the total area of retrograde cavity and the filled area. The radiographic density mean of each third of retrograde cavity filled with MTA was measured by using the histogram tool of the software. The results were submitted to ANOVA and Tukey tests, with 5% of significance. Results: There was no difference in percentage of filling among the groups (p > 0.05) (approximately 85%). By comparing the thirds, the condenser and MTA applicator groups showed higher density for apical and middle third than cervical third (p < 0.05). The ultrasound group presented similar density among the thirds. Conclusion: The filling ability was similar for the studied methods. Ultrasound promoted better distribution of MTA in retrograde cavity, but did not increase the density of material.

Modelo fuzzy estimando tempo de internação por doenças cardiovasculares

Abstract A fuzzy linguistic model based on the Mamdani method with input variables, particulate matter, sulfur dioxide, temperature and wind obtained from CETESB with two membership functions each was built to predict the average hospitalization time due to cardiovascular diseases related to exposure to air pollutants in São José dos Campos in the State of São Paulo in 2009. The output variable is the average length of hospitalization obtained from DATASUS with six membership functions. The average time given by the model was compared to actual data using lags of 0 to 4 days. This model was built using the Matlab v. 7.5 fuzzy toolbox. Its accuracy was assessed with the ROC curve. Hospitalizations with a mean time of 7.9 days (SD = 4.9) were recorded in 1119 cases. The data provided revealed a significant correlation with the actual data according to the lags of 0 to 4 days. The pollutant that showed the greatest accuracy was sulfur dioxide. This model can be used as the basis of a specialized system to assist the city health authority in assessing the risk of hospitalizations due to air pollutants.

Fatores ergonômicos críticos de mochos odontológicos e sua relação com a produtividade e satisfação de cirurgiões dentistas

The purpose of the ergonomics is to generate adequate working conditions, by the correct use of equipment and appropriate anatomic positions. Ergonomics has become essential in the dentist's life while in the dental practice. The misuse of equipment in performing tasks or the wrong choice of equipment can initiate various problems like back pain, bursitis, repetitive strain injury (RSI), limitation of movement, and stress. Using a survey that was implemented with professional dentists linked to Paulista Association of Dental Surgeons (APCD) and graduate students at the Universidade Estadual Paulista (UNESP) in the São José dos Campos (SP) region, this study intends to propose an adequate research instrument to identify ergonomic critical factors of dental stools and their relation to productivity and satisfaction of dentists. The survey was developed with Google Docs Forms tool and was designed by analysis of other studies, existing surveys and other papers in this area. Relevant content were discussed and developed questions about the stool used by dentists in their activities, the occurrence of any problems arising from the exercise of their profession and the views of respondents about the influence of using the dental stool in these cited problems as well as their productivity. Due to obstacles encountered during the project, particularly bureaucratic issues, the survey cannot be implemented as needed, resulting in a test with reduced number of answers. The users' opinion varies according to the stool used, bringing some difficulty to generalizing the answers, but if treated properly, it is possible to obtain relevant conclusions about the main aspects perceived by users in relation to the stool and the needs pointed as most important
