A pesquisa busca identificar as questões relacionadas aos estudos de Comunicação na Usabilidade de interfaces. O estudo é desenvolvido com revisão bibliográfica da Interação Humano-Computador e da Usabilidade. As revisões da interação humano-computador se dá considerando três principais eixos: Engenharia de software, Engenharia de Fatores Humanos e Design gráfico. Neste sentido, faz-se um recorte na importância das investigações e das propriedades comunicacionais que viriam a surgir nas relações suportadas pela interface de sistemas e das qualidades e características que determinam a usabilidade de interfaces. Observa-se que, apesar das características e propriedades comunicacionais serem intrínsecas as tecnologias digitais da informação, o envolvimento da Comunicação nestes processos de investigação ou construção de tecnologias interativas são superficiais e oferecem certo distanciamento dos aspectos tecnológicos. Denota-se, portanto, que as contribuições sobre aspectos da interação entre homem e máquina suportadas por interfaces comunicacionais são estritamente técnicas e oriundas de outros campos do conhecimento, apesar da existência da Teoria Mátemática da Comunicação e da sua origem em meios técnicos de comunicação como o telégráfo. Verifica-se assim a possibilidade de um maior envolvimento da Comunicação não apenas nas investigações relacionadas à usabilidade de sistemas interativos, como também na contribuição dos seus processos de desenvolvimento de sistemas baseados em diálogos.

Este trabalho tem por objetivo investigar e discutir o showroom como meio de comunicação com o mercado, sob a ótica da Comunicação Integrada de Marketing. Busca-se compreender como o showroom é capaz de envolver emocionalmente os consumidores, por meio de estímulos sensoriais aos sentidos humanos (tato, olfato, visão, audição e paladar), a ponto de materializar um sonho de consumo dos clientes. Assim, o objeto de estudo é a atmosfera de vendas, cuja mensagem polissêmica é utilizada em showroons com apartamento decorado na construção civil. Sua relevância, está justamente no fato de ser uma estratégia amplamente utilizada pelas empresas na atualidade. Porém, nota-se que há uma carência de estudos relacionados ao tema, o que justifica a realização da dissertação e a opção por uma abordagem qualitativa na metodologia. Por tratar-se de um fenômeno contemporâneo inserido num contexto da vida real, não enquadrado como caso raro ou revelador, a estratégia de pesquisa adotada é o Estudo de Casos Múltiplos, ancorado nos procedimentos de pesquisa bibliográfica, observação direta e entrevistas semiestruturadas. Os resultados da pesquisa revelam que o showroom é um meio de comunicação sintonizado com os anseios do consumidor contemporâneo, que valoriza as experiências sensoriais.

Estudo sobre os processos comunicativos envoltos na transformação dos hábitos culinários da comunidade quilombola da Fazenda Picinguaba de Ubatuba, SP. O objetivo é entender as origens e as causas que provocaram alterações nos hábitos culinários da comunidade do Quilombo da Fazenda, a partir de uma análise comparativa entre os fazeres primitivos e os praticados hoje. Foi analisado também o processo comunicacional desenvolvido para a transmissão da cultura alimentar entre as gerações, identificando as linguagens utilizadas. Como instrumento para o entendimento desses fenômenos, esta pesquisa foi realizada à luz das teorias e conceitos dos estudos culturais; dos conceitos sobre comunidades e identidades, além da teoria da folkcomunicação desenvolvida por Luiz Beltrão. Para tanto, foi realizada pesquisa bibliográfica e estudo de documentos, além de entrevistas utilizando-se a modalidade história oral com os membros da comunidade. Os resultados obtidos apontam uma mudança nos hábitos alimentares da comunidade do Quilombo da Fazenda, devido à facilidade de acesso ao comércio de gêneros alimentícios, decorrente da construção da rodovia Rio-Santos, e a influência trazida pela televisão, a partir da implantação da rede de energia elétrica em 2008. No entanto, observamos que apesar dessa mudança, a base da cultura alimentar quilombola vem mantendo muito dos seus aspectos originais. A comunicação dentro da comunidade quilombola e a transmissão dos saberes e fazeres tradicionais da comunidade ocorrem predominante pela oralidade. Identificamos a presença de dança, música, roda de conversa, culinária, artesanato que correspondem aos gêneros da folkcomunicação.

Bem-estar no trabalho, percepção de suporte do supervisor e estilos de liderança são temas que vêm despertando atenção crescente nos últimos tempos, de diversos pesquisadores no campo de estudos do comportamento organizacional. O objetivo desta pesquisa foi investigar o impacto da percepção do suporte do supervisor e dos estilos de liderança no bem-estar no trabalho. O construto bem-estar no trabalho no presente estudo foi representado por duas dimensões: satisfação no trabalho e comprometimento organizacional afetivo. A amostra foi composta por 200 trabalhadores que atuavam em empresas privadas e públicas, situadas no Estado de São Paulo, sendo 110 mulheres e 90 homens, distribuídos entre solteiros e casados. O instrumento de coleta de dados foi um questionário composto por quatro escalas que mediram as variáveis: percepção de suporte do supervisor, estilos de lideranças, satisfação no trabalho e comprometimento organizacional afetivo. Para a análise dos dados utilizou-se um programa estatístico. Foram calculadas estatísticas descritivas das variáveis do estudo (médias, desvios-padrão e correlações bivariadas) e modelos de regressão multivariada para se investigar os impactos causados por percepção do suporte do supervisor e por estilos de liderança sobre bem-estar no trabalho, representado por vínculos com o trabalho (satisfação no trabalho) e com a organização (comprometimento organizacional afetivo). Os resultados deste estudo, revelaram maiores impactos do suporte do supervisor do que de estilos de liderança sobre bem-estar no trabalho. Ao final, algumas considerações e recomendações serão feitas destacando-se a importância do bem-estar no trabalho sobre a saúde dos trabalhadores e das organizações.

A obesidade é uma doença crônica que vem acometendo, progressivamente, cada vez mais pessoas no mundo. Por ser uma patologia de difícil controle que favorece a eclosão de outros agravos à saúde, é premente a necessidade de realização de pesquisas que possam contribuir para o aperfeiçoamento dos tratamentos, bem como para a melhoria da qualidade de vida e eficácia adaptativa. Sendo assim, a presente pesquisa visou avaliar a percepção da qualidade de vida (QV), a eficácia adaptativa (EDAO) e o funcionamento global (AGF) de pessoas com obesidade, relacionando os resultados obtidos na avaliação da percepção da QV com os da eficácia adaptativa, bem como aos do funcionamento global (AGF). Para tanto, utilizou-se o questionário WHOQOL-100 versão em português para avaliação da percepção de qualidade de vida, a Entrevista Diagnóstica Preventiva Escala Diagnóstica Adaptativa Operacionalizada (EDAO) para a eficácia adaptativa e a Escala de Avaliação do Funcionamento Global (AGF) para o funcionamento global. Este estudo contou com a participação de trinta mulheres obesas (Índice de Massa Corporal IMC >=30 kg/m2), com idade média de 52,33 anos, que utilizavam os serviços de um ambulatório situado na região do Grande ABC, estado de SP. A maioria das participantes se encontrava no grau I de obesidade - 46,70%, situava-se no grau II 33,30% e 20,00% no grau III. O aumento de peso da maioria teve início nas gestações (43,30%), o segundo período onde ocorreu o início do descontrole do peso corporal foi entre os 40 aos 50 anos (20,00%). Na avaliação geral da QV, observou-se que no domínio VI Aspectos Espirituais/Religião/Crenças Pessoais foi encontrado o maior escore médio (16,17 - DP=2,95 [equivalente a 80,83% do escore máximo que poderia ser obtido]), comparando-o com os demais domínios avaliados. Em oposição, o domínio I Físico foi o que apresentou o menor escore médio (11,77 - DP=2,78 - 58,83%). Todas as participantes se encontravam em ineficácia adaptativa: Grupo 2 Ineficaz Leve (26,7%), no Grupo 3 Ineficaz Moderada (33,3%) e no Grupo 4 Ineficaz Severa (30,0%). Quanto à avaliação do funcionamento global (AGF), notou-se que 36,67% se situavam no intervalo entre 51-60 pontos. 23,33% das participantes no intervalo entre 31-50 pontos. Apenas 23,33% tiveram pontuação acima de 70 pontos. Relacionando os resultados das avaliações, foram encontradas correlações fortes, positivas e significativas entre a avaliação da percepção de qualidade de vida, da eficácia adaptativa e do funcionamento Global.

The evidence of the water theme in news reports is configured as an important topic of interest to contextualize, problematize and/or generate meaning in the midst of discussion of a content from different levels of education and/or disciplines of basic education. The possibilities to use this theme in classroom is also highlighted in Brazilian official documents that guide the practice of teachers of all Brazilian curricular components of this educational level. So, the theme water can be used as subsidy to teach chemistry, since contextualises the teaching of this discipline aiding in the discussion of different chemical concepts. In this perspective, the meaningful learning theory, developed by David Ausubel, has constructivist nature and says that an individual learns significantly when he can relate new information with a specific knowledge structure that integrates the prior knowledge of its structure. In this sense, the use of water as a theme for the approach prior knowledge of chemical concepts has already been characterized as an important topic that can give meaning to the content of education in chemistry. In this dissertation, a teaching unit potentially significant (TUPS) is presented based on meaningful learning theory of David Ausubel approaching the theme water. approaching the theme water. The unit was used in a class of thirty-five students of the 2nd year of high school, a public school in the city of Extremoz-RN, metropolitan region of Natal / RN. Through it was possible to discuss an issue of interest to students of the school to address the chemical contents, such as solutions, physicochemical aspects and stages of water treatment. At first, an initial questionnaire was used to identify the students' previous ideas on the topic under study to the concept of chemical solutions. It was subsequently developed and implemented a series of activities based on students' ideas. To subsidize the sequence, it was prepared four booklets that worked the content of chemical solutions, contextualizing the theme water. The results of this work showed that the alternative conceptions that students have about concepts related to the chemical solutions are similar to the ideas of other students presented in the literature and that the development of the TUPS, allied to the contextualization strategy with the theme water, not only motivated the students for the teaching of chemical content, as yet provided the learning of chemical concepts not in isolation, but making a connection between their ideas and experiences with scientific knowledge. To this, beyond of dialogued lectures, were also used strategies as experimental activities, problem solving, group discussions and construction of concept maps. The final evaluation of the unit was conducted by a questionnaire based on the Likert scale, answered individually by students, who approved the unit as conducive to teaching and learning of chemistry process

Obesity is a chronic disease that has multi-factorial aetiology, characterized by high degree of body fat; the degree of obesity will vary according to the Body Mass Index (BMI=m2 /kg). The severe degree of obesity is characterized by BMI>40 and it is regularly associated to endocrine-metabolic or mechanic clinical alterations, and to psychological disorders. Binge Eating (BE) results were overly high for this population. The Bariatric Surgery has been the treatment chosen by those diagnosed with severe obesity as this intervention provides prompt outcomes for loss of weight and clinical improvement conditions. However, recent research has acquiesced that after two years between 20% and 30% of people subject to this intervention gained weight. The main objective of this research is to assess the psychological and behavioral characteristics of those diagnosed with severe obesity that have been subject to Gastric Bypass Surgery in the past 24 months. Specific aspects were investigated: (1) characteristics of different personalities and diagnose of clinic and personality disorders; (2) BE and its relation with loss of weight; (2) the difference between the groups regarding post-surgery care, e.g. physical activity, psychological and dietician input. Method: 40 adults (women and men) aged 23 and 60 year-old who went through a bariatric surgery in the past 24 months, in the city of Natal-RN (Brazil); they were assembled in two groups n=20, Gain group displaying loss of < 50% of their initial surplus of weight, and the Loss group displaying loss of >50%. The research protocol is made of a socio-demographic questionnaire and 3 psychometric instruments: Rorschach – Comprehensive System; Millon Personality Inventory (MCMI-III); and the Binge Eating Scale (Escala de Compulsão Alimentar Periódica (ECAP). Through Rorschach significant differences between these groups were verified according to the kind of personality (EB) - more EB Extratensivo in Gain group and Intratensivo in Loss group – and the lack of control to express affect, increasing the answer for Color Pure at Group I. Concerning the people standardization, the sample as a whole tends to show psychic pain, denigrated selfperception, high levels of self-criticism, distorted perceptions, vulnerability to develop mood disorders and high scores regarding Suicide. MCMI-III results showed more clinic and personality disorders in Group I: Depressive Disorder and Schizotypal, Anxiety, Dysthymia, Major Depressive Disorder; Thought Disorder, Bipolar- Manic and Posttraumatic Stress Disorder. In relation to ECAP, the results indicated significant differences, showing increased BE results in Gain group. There were found significant differences between BE severity and the presence of clinic and personality disorders. Concerning the post-surgery care, the observed differences are statistically significant regarding physical activities with median-increased differences in Loss group. There is a difference between the initial weight and the time post-surgery, indicating that the higher the initial weight and the time after the surgery the higher the re-gain of weight post-surgery. Finally, the results show that the participants with more than 3 years of surgery will have Clinic and Major Depressive Disorders; Somatoform Disorder; Dysthymia. These results confirm prior studies related to BE post-surgery and re-gain of weight as well as the proneness of clinic disorders in severe obesity people. That means the results reinforce that the surgery process is a facet of the severe obesity treatment. The post-surgery process needs to be the main focus of attention and have a long-term input to sustain the care of the surgery results and the quality of life of the patients.

This study aims to understand the growth dynamics of Ceará-Mirim city considering the aspects that define its current urban sprawl. We chose to use as methodological approach the concept of space as a product and producer of social relations and the same constitutes by objects and actions that relate in a dialectical process over time. As a research tool, it took place bibliographical study that features the historical aspects of use and occupation, in order to evidence the regional ground agents that explain its current urban setting. Then, it was collected a secondary data of economic analysis activities from municipality and their impact on local social structure. Between these aspects, the sugar economy, even in decline, had appeared as defining the boundaries of urban growth. At the regional scale, other factors were discussed in a way of urban influence processes forming the Greater Natal (RMNatal), and Ceará-Mirim appears integrating into this scale in a very low level according to Metropolis Observatory (2012). However, we have pointed out that in recent years, especially in growth vector of BR 406, settled metropolitan scope equipment. These objects have been associating in a real estate sector's reasoning while the possible "metropolization" have been promoting as investments in the city's expansion area.

This thesis was performed in four chapters, at the theoretical level, focused mainly on electronic density. In the first chapter, we have applied an undergraduate minicourse of Diels-Alder reaction in Federal University of Rio Grande do Norte. By using computational chemistry tools students could build the knowledge by themselves and they could associate important aspects of physical-chemistry with Organic Chemistry. In the second chapter, we studied a new type of chemical bond between a pair of identical or similar hydrogen atoms that are close to electrical neutrality, known as hydrogen-hydrogen (H-H) bond. In this study performed with complexed alkanes, provides new and important information about their stability involving this type of interaction. We show that the H-H bond playing a secondary role in the stability of branched alkanes in comparison with linear or less branched isomers. In the third chapter, we study the electronic structure and the stability of tetrahedrane, substituted tetrahedranes and silicon and germanium parents, it was evaluated the substituent effect on the carbon cage in the tetrahedrane derivatives and the results indicate that stronger electron withdrawing groups (EWG) makes the tetrahedrane cage slightly unstable while slight EWG causes a greater instability in the tetrahedrane cage. We showed that the sigma aromaticity EWG and electron donating groups (EDG) results in decrease and increase, respectively, of NICS and D3BIA aromaticity indices. In addition, another factor can be utilized to explain the stability of tetra-tert-butyltetrahedrane as well as HH bond. GVB and ADMP were also used to explain the stability effect of the substituents bonded to the carbon of the tetrahedrane cage. In the fourth chapter, we performed a theoretical investigation of the inhibitory effect of the drug abiraterone (ABE), used in the prostate cancer treatment as CYP17 inhibitor, comparing the interaction energies and electron density of the ABE with the natural substrate, pregnenolone (PREG). Molecular dynamics and docking were used to obtain the CYP1ABE and CYP17-PREG complexes. From molecular dynamics was obtained that the ABE has higher diffusion trend water CYP17 binding site compared to the PREG. With the ONIOM (B3LYP:AMBER) method, we find that the interaction electronic energy of ABE is 21.38 kcal mol-1 more stable than PREG. The results obtained by QTAIM indicate that such stability is due a higher electronic density of interactions between ABE and CYP17

The inadequacy about eating habits have been established as a serious problem nowadays. It is a multifactorial and difficult to handle, given their different nuances and causes. A population particularly exposed to the bad eating habits arising harm are individuals with Down syndrome, both with regard to the aspects inherent to the individual's own condition, regarding eating misfits, making it the weight control a necessary measure for a proper development. Thus, this study aimed to develop and evaluate a proposal based nutrition education from the assumptions of mediated learning, with children three to four years with Down syndrome. The participants were five children, four girls and a boy. Also included his parents and / or guardians. The data collection procedure involved the use of eight playful workshops with children and nutritional evaluation of those five meetings with parents and three home visits with each participating family. We tried to build with these children and their families a nutritional education to contribute to their daily choices of eating. Using listening, observation and questionnaire, besides playful interventions, it was observed that the first meaning of the act of eating is built in the family and reinforced by their social life. Overall, our sample characteristics seem to agree with the literature. During the intervention, the children showed attention, but little understanding of the content. With mothers, the results were different, with reflections on the inadequate power both the type of food offered, and quantity and so this offer is performed, conducted along the interventions changes in your lifestyle, such as perception of influence they had on their children in the formation of their eating habits, as well as less frequent intake of soft drinks and sweets. Nutritional interventions and mediations conducted with the mothers is that they seem to be effective strategies to combat obesity. Face of what was discussed, we see the importance of implementing intervention measures in combating and preventing overweight or obese since childhood, particularly with children with Down syndrome. One should prevent childhood obesity with educational and informative measures from birth, with family and with each child, through the primary health care and schools.

Objetivo: relatar a evolução de uma série de casos de gestação em mulheres previamente submetidas à cirurgia de bypass gástrico para tratamento de obesidade grave. Métodos: cinco casos consecutivos de gravidez após gastroplastia ocorridos entre 2001 e 2004 foram avaliados. As pacientes tinham idade entre 30 e 34 anos e todas haviam sido submetidas à cirurgia de Capella. Aspectos clínicos, laboratoriais e do acompanhamento materno e fetal foram considerados, durante o período gestacional e após o parto. Foi realizada revisão da literatura internacional, por meio das bases de dados MEDLINE e Web of Science, utilizando os seguintes unitermos: gastroplasty, gastric bypass surgery, bariatric surgery e pregnancy. Resultados: todas as gestações observadas foram únicas e não ocorreram complicações obstétricas, durante o seguimento pré-natal e parto. Também não houve registro de recém-nascidos prematuros ou de baixo peso ao nascimento. Conclusão: nossos dados sugerem que a gravidez após gastroplastia é segura para a mãe e feto. Entretanto, em virtude do limitado volume de informação disponível sobre o tema, investigações adicionais são necessárias para estabelecer recomendações apropriadas com relação ao seguimento dessas gestações _________________________________________________ABSTRACT Purpose: we report a small series of pregnant women who underwent gastric bypass surgery for severe obesity, with a review of the literature on this topic. Methods: five consecutive cases of pregnancy after gastroplasty between 2001 and 2004 were evaluated, and clinical, laboratory and therapeutic features were considered. Patients were 30 to 34 years old and all had been submitted to gastroplasty by the Capella technique. The outcomes for both the pregnant woman and the fetus were evaluated. A search of the English language literature was done through MEDLINE and Web of Science databases with the following terms: gastroplasty, gastric bypass surgery, bariatric surgery, and pregnancy. Results: all 5 pregnancies were singleton. No major obstetric complications were observed and there were no premature or lowbirth weight infants. Conclusion: our data suggest that pregnancy following gastroplasty is safe for mother and fetus. However, since information about this topic is limited, further investigations are required to establish appropriate recommendations concerning the follow-up of these pregnancies
