Basic prerequisites are a thorough knowledge of chemical and physical properties of pure components and mixtures, of reactions, and of mathematical models which, in combination, allow the calculation of a process in a computing device.Process simulation software describes processes in flow diagrams where unit operations are positioned and connected by product or educt streams. The software has to solve the mass and energy balance to find a stable operating point. The goal of a process simulation is to find optimal conditions for a process.Keywords: chemical engineering, chemical engineer, process modeling, process simulation, thermodynamics, thermophysical properties

TDAH MENTE Diagnóstico

O TDAHMENTE resulta de um trabalho desenvolvido por alunos do Ensino Médio do Instituto Estadual de Educação Carmela Dutra – Porto Velho-RO, sob a coordenação do professor de informática da Instituição. Utilizando ferramentas e espaço do Programa Nacional de Tecnologia Educacional (PROINFO), foi criado o aplicativo digital TDAHMENTE, uma ferramenta digital com o objetivo de identificar possível diagnóstico do Transtorno de Déficit de Atenção e Hiperatividade (TDAH) em alunos da educação básica, auxiliando pais de alunos, professores, coordenadores e psicólogos. O aplicativo foi desenvolvido a partir do ensino de linguagem de programação a alunos do Ensino Médio, criação de artes gráficas e pesquisas bibliográficas ao referencial teórico cientifico. O aplicativo TDAHMENTE possibilita aos usuários apropriação de autoconhecimento sobre o TDAH que consiste em uma desordem comportamental com base neurológica frequente na infância (RICHTERS, et., all, 1995) caracterizado por graus diferenciados de desatenção, impulsividade e, em alguns casos, hiperatividade (CHADD, 2001 apud FERREIRA, 2011) . De acordo com Lacet e Rosa (2017) a pesquisa com 5.961 jovens de 18 estados do país, identificou que no cenário nacional 4,4 % da população de crianças e adolescentes entre 04 e 18 anos de idade possuem TDAH, trata-se do primeiro estudo epidemiológico sobre TDAH feito no Brasil com abrangência em todo o território. O índice se assemelha aos observados em outras partes do mundo, que indicam a presença de TDAH em 5% dos jovens. A maior problemática em tratar o TDAH é a falta de diagnóstico, e o TDAHMENTE surgiu, nessa conjuntura, como proposta de ferramenta alternativa para auxiliar as pessoas a ter conhecimento e buscar identificar um possível diagnóstico para os transtornos de atenção e hiperatividade. As pesquisas que nortearam a criação do aplicativo revelaram que os sintomas do TDAH permanecem na vida adulta em 67% dos casos (LOPES, NASCIMENTO e BANDEIRA, 2005) e trazem implicações à rotina da criança e da família, bem como consequências ao sistema educacional e maior incidência de condutas de risco na adolescência (HERNÁNDEZ, 2007). Frequentemente relaciona-se ao insucesso educacional, baixa performance profissional, perda na renda familiar, impacto econômico e social (BIEDERMAN e FARAONE, 2006; ROHDE e HALPERN, 2004). Para fundamentação do aplicativo foi utilizado como referência os dados disponíveis no Manual Diagnóstico e Estatístico de Transtorno Mentais (DSM, 2014), um conjunto de questões formuladas pela Associação Americana de Psiquiatria que permite apenas ao profissional médico diagnosticar o TDAH. A transformação do DSM em um formulário digital como aplicativo não substitui o profissional médico, mas o torna uma ferramenta auxiliar que busca fornecer informações baseadas em pesquisas cientificas que resultem indicadores potenciais para um nível elevado do transtorno. O Indicador de TDAH é uma ferramenta e recurso indispensável para que o usuário possa se apropriar de conhecimento e avaliar a possível necessidade de procurar ajuda de um profissional médico de acordo com os resultados obtidos no aplicativo. O projeto é inovador pois substitui os velhos métodos tradicionais e defasados que ainda são utilizados por profissionais da educação na busca de identificar possível diagnóstico TDAH em crianças e adolescentes no âmbito escolar, pois, muitos formulários utilizados atualmente são reproduções da internet e possuem metodologia questionável. O TDAHMENTE possui respaldo científico na medida em que foi construído com base no DSM. Além das pesquisas científicas realizadas pelos pesquisadores o desenvolvimento do aplicativo contou com a colaboração de um profissional médico de psiquiatria que nos ofereceu todos os recursos e suporte para o desenvolvimento da ferramenta.The TDAHMENTE results from a work by students of Eastern State Institute of Education Education Carmela Dutra - Porto Velho-RO, under the coordination of the institution's computer teacher. Using tools and space of the National Program of Educational Technology (PROINFO), the TDAHMENTE digital application, a digital tool in order to identify possible diagnosis of Attention Deficit Disorder Attention Deficit Hyperactivity Disorder (ADHD) in pupils of basic education was created, helping parents students, teachers, engineers and psychologists. The application was developed using the programming language of teaching high school students, creation of graphic arts and literature searches to scientific theoretical. The TDAHMENTE application enables self grabbing members on ADHD consisting of a behavioral disorder with frequent neurological basis in childhood (Richters et., All, 1995) characterized by different degrees of inattention, impulsivity and, in some cases, hyperactivity ( CHADD, 2001 cited FERREIRA, 2011). According to Lacet and Rosa (2017) research with 5,961 young people from 18 states of the country, found that in the national scenario 4.4% of the population of children and adolescents from 04 to 18 years of age have ADHD, it is the first epidemiological study on ADHD done in Brazil with coverage throughout the territory. The index is similar to those observed in other parts of the world, which indicate the presence of ADHD in 5% of young people. The major problem in treating ADHD is the lack of diagnosis, and TDAHMENTE emerged at this juncture, as a proposal for an alternative tool to help people to be aware and seek to identify a possible diagnosis for attention deficit hyperactivity disorders. The research that guided the creation of the application revealed that ADHD symptoms persist into adulthood in 67% of cases (LOPES, Birth and FLAG, 2005) and have implications to the routine of the child and family as well as consequences for the educational system and higher incidence of risk behaviors in adolescence (Hernandez, 2007). Often it is related to educational underachievement, low professional performance, loss of family income, economic and social impact (Biederman and FARAONE, 2006; ROHDE and HALPERN, 2004). For application reasons was used as reference data available in the Diagnostic and Statistical Manual of Mental Disorders (DSM 2014), a set of questions from the American Psychiatric Association that only allows the medical professional to diagnose ADHD. The transformation of DSM into a digital form as application does not replace medical professional, but makes an auxiliary tool that aims to provide information based on scientific research resulting potential indicators to a high level of disorder. ADHD Indicator is a tool and indispensable resource for the user to take ownership of knowledge and to evaluate the possible need to seek help from a medical professional according to the results obtained in the application. The project is innovative because it replaces the old traditional and outdated methods that are still used by education professionals in order to identify possible diagnosis ADHD in children and adolescents in schools, because many forms currently used are the internet reproductions and have questionable methodology. The TDAHMENTE has scientific backing in that it was built on the DSM. In addition to the scientific research conducted by researchers application development with the collaboration of a professional doctor of psychiatry who offered us all the resources and support for the development of the tool.
