RE:VISÃO: habitat nos anos 1960 / RE:VISION: habitat in the 1960s

Miyasaka, Elza Luli 03 May 2011 (has links)
O objetivo do trabalho é compreender alguns princípios norteadores do habitat na década de 1960 através da análise da cidade com as megaestruturas de Yona Friedman; da análise do material teórico de Kisho Kurokawa sobre as cápsulas; e sobre o processo de produção através da industrialização de João Filgueiras Lima - Lelé. As megaestruturas de Yona Friedman eram estruturas com funções de cidade, utilizavam tecnologias emergentes e o objetivo era acolher a população como espaço do habitar. As cápsulas eram componentes do habitar, envoltórios ou invólucros para o habitar humano, produzidos industrialmente, propunham a autonomia e simbiose entre máquina e homem. A industrialização para João Filgueiras Lima era compreendida como instrumento para atingir a equidade e resultado da consciência social e coletiva. Para Lima, o habitat era constituído pelas partes necessárias para o desenvolvimento do ser humano, composto pela urbanização, habitação e equipamentos sociais. / The objective of this essay is to comprehend the guiding principles of habitation in the 1960s through the analysis of the city with Yona Freidman\'s megastructures; of Kisho Kurokawa didatic materials regarding capsules; and João Filgueiras Limas production process through industrialization. The megastructures of Yona Friedman were structures with functions of a city, utilized emerging technologies and their objective was to shelter the population in a living space. The flexibility of the environments, the users mobility and participation were fundamental. The capsules, components of the living, involucres to the human living and industrially produced, proposed autonomy and symbiosis between man and machine. The industrialization was comprehended as an instrument to achieve fariness and result of the collective social conscience. To Lima, the habitat is composed by the necessary parts for the human development, composed by the urbanization, habitation and social equipments.

[pt] A presente pesquisa de mestrado busca entender a Arquitetura da Informação de sistemas hipertextuais - onde o atual processo de desenvolvimento considera equivocadamente os usuários - usando como estudo de caso websites de universidades cariocas. Objetiva-se com a pesquisa melhorar a usabilidade de websites, facilitando a navegação e localização de informações por parte das pessoas que interagem com o sistema hipertextual, apontando implicações para a Arquitetura da Informação. Alguns métodos e técnicas foram usados, em quatro etapas: 1. Através de Pesquisa Exploratória, buscou-se perceber o que pensam os desenvolvedores sobre a construção de um website universitário e, de outro lado, a experiência vivida pelos usuários em sites desta natureza; 2. Através da Ergonomia Participativa, buscou-se conceber a Arquitetura da Informação de um website universitário: 2.2 Eliciando o Modelo Mental dos usuários com relação à organização e agrupamento da informação; 2.3 Conhecendo a tarefa de navegação e mapeando seus fluxos; 3. Através da Análise Ergonômica da Tarefa, buscou-se avaliar a Arquitetura da Informação dos sites selecionados no estudo de caso; 4. Com a Avaliação de Especialistas, comparou-se os resultados dos métodos da Etapa 2 com a Arquitetura da Informação encontrada nos websites universitários selecionados como estudo de caso. Confirma-se a hipótese da pesquisa, atestando que as soluções de Arquitetura da Informação propostas pelos desenvolvedores não facilitam o uso do sistema, onde o usuário não consegue executar facilmente a tarefa desejada. / [en] This research for master degree seeks to understand the Information Architecture of hypertextual systems - in which the users are neglected by today s process of development - having the study of case based on the websites of some of Rio de Janeiro universities. It is intended, with the research, to improve the websites usability, making the navigation and localization of information easier for the people who interact with the hypertextual system, pointing out the implications to the Information Architecture. A few methods and techniques were used, in four steps: 1. Through exploratory research, it was sought to perceive what the developers think about the construction of a university website and, on the other side, what the users experience when they navigate on such sites; 2. Through Participatory Ergonomics, it was sought to conceive the Information Architecture of a university website: 2.2 By eliciting the users Mental Model with regard to the information organization and assemblage; 2.3 By knowing the navigation task and making the flow chart; 3. Through the Ergonomics Analysis of the Task, it was sought to assess the Information Architecture of the sites selected in the study of case; 4. With the Assessment of Specialists, the results of Step 2 methods were compared with the Information Architecture found in the universities websites selected as the study of case. The theory of the research has been confirmed, attesting that the Information Architecture solutions proposed by the developers do not facilitate the use of the system, where the user is not able to easily accomplish the desired task.

Por isso, necessitam de instrumentos que permitam agilidade para adaptar suas estratégias, processos e sistemas µas necessidades de cada momento. A Arquitetura Empresarial (AE) tem sido identificada por pesquisadores como a abordagem adequada para prover a agilidade organizacional, pois permite o conhecimento dos elementos organizacionais favorecendo planejar e realizar as mudanças necessárias. Entretanto, a AE ainda não é uma realidade para a maioria das organizações. Os motivos são a complexidade inerente, a falha das abordagens atuais para lidar com essa complexidade e o custo das ferramentas envolvidas. A AE é uma disciplina em desenvolvimento e requer princípios, teorias e instrumentos adequados µa sua natureza e acessíveis a organizações de qualquer porte. Nesse contexto, este estudo identifica um novo referencial teórico: a AE como Arquitetura de Informação Organizacional (AIO). O estudo propõe, ainda, uma abordagem para a AIO, que se fundamenta nos princípios da colaboração organizacional e nos métodos frágeis. Seu principal objetivo é reduzir a complexidade e o custo da AIO. A solução proposta é avaliada em estudo de caso em uma instituição do sistema financeiro brasileiro. ______________________________________________________________________________ ABSTRACT / Currently, organizations operate in an environment marked by constant changes. Thus, they need instruments bringing agility to adopt their strategies, processes and systems to each moment needs. Enterprise Architecture (EA) has been identified by researchers as the approach suitable to the organizational agility as it allows the know-ledge of different organizational elements leading to planning and accomplishment of the changing actions. However, AE has not comprised the most part of organizations yet. The reasons are due to its complexity, the current approach failure to deal with the complexity and the cost of the tools involved. AE is an on-going process discipline and it requires appropriate principles and specific theories and instruments for organizations of any size. In this context, this study identifies a new theoretical framework: EA as Architecture of Information for Organizations (AIO) and proposes a new approach that is based on the principles of organizational collaboration and agile methods. Its main objective is to reduce complexity and cost of AIO. The proposed solution is evaluated on a case study in an institution of the Brazilian financial system.

[en] INFORMATION ARCHITECTURE AND E-GOVERNMENT: CITIZENS-STATE DIALOGUE ON THE WORLD WIDE WEB - CASE STUDY AND ERGONOMIC EVALUATION OF HUMAN-COMPUTER INTERFACE USABILITY / [pt] ARQUITETURA DE INFORMAÇÃO E GOVERNO ELETRÔNICO: DIÁLOGO CIDADÃOS-ESTADO NA WORLD WIDE WEB - ESTUDO DE CASO E AVALIAÇÃO ERGONÔMICA DE USABILIDADE DE INTERFACES HUMANO-COMPUTADOR

LUIZ CARLOS AGNER CALDAS 17 January 2008 (has links)
[pt] Este trabalho analisa aspectos do diálogo cidadãos-Estado na World Wide Web, considerando a configuração dos meios técnicos de comunicação interativa disponibilizados pela Internet e a otimização deste processo pelos profissionais de Design. O objeto de estudo é a usabilidade e a Arquitetura de Informação do portal IBGE - um portal emblemático para a implantação de serviços de governo eletrônico (e-Gov) no Brasil. Este portal disponibiliza grande quantidade de dados estatísticos, socioeconômicos, geocientíficos e ecológicos, que servem como embasamento para políticas e ações sociais do Estado e pautam o seu diálogo com a sociedade civil. A tese analisa pontos fortes e fracos da Arquitetura de Informação do portal e questiona - sob o ponto de vista da usabilidade - a sua eficácia em disseminar informações para toda a sociedade com amplo acesso de cidadãos. Em sua dimensão teórica, o trabalho investiga as conexões da Arquitetura de Informação com a Ciência da Informação e com a Teoria das Organizações, aplicadas ao estudo de caso. No inventário de conteúdos informacionais e no estudo do contexto, trabalhou-se com a técnica de entrevistas de história oral. No estudo de usuários, considerou-se a interação do portal com as audiências, enfatizando comportamentos de busca de informação, tarefas e modelos mentais, em contraponto ao volume de dados disponibilizados e à sua complexidade. A partir da identificação de grupos da audiência-alvo, foram aplicados testes de interação, com a participação de estudantes de graduação e de pós-graduação (mestrandos e doutorandos), para a avaliação de usabilidade. Em pano de fundo, discutem-se questões relacionadas a mudanças no Estado, a partir da proposta de governo eletrônico (e-Gov). / [en] This work analyses aspects of the citizens-state dialogue in the World Wide Web, considering the technical configuration of interactive resources in the Internet as well as the optimization of this process by designers. The study object is the usability and Information Architecture aspects of the IBGE portal. This portal is an emblematic example of the Brazilian e- Government communication challenges. This site disseminates large amount of statistical data - socioeconomic, ecological and geographical - that contributes to the formulation of state policies and social action, as well as helps in its dialogue with civil society. This thesis analyses the strongest and weakest points of the IBGE site Information Architecture and evaluates - from the usability point of view - its effectiveness in granting wide access to information to society as a whole. In the theoretical dimension, the work investigates possible connections among Information Architecture, Information Science and Organization Theory applied to the case study. Oral history interview techniques were applied in content inventory and context research. To study user behavior research, this thesis investigated information search, mental models and user tasks. Based on the identification of target audience groups, field usability tests were run with the participation of graduate and post-graduate students. Throughout this work, institutional change issues related to the e-Gov initiative in Brazil were discussed.

[en] HUMAN-FACTORS AND USABILITY ON WEBFORMS: A CASE STUDY OF E-COMMERCE / [pt] ERGONOMIA E USABILIDADE EM FORMULÁRIOS ELETRÔNICOS NA INTERNET: UM ESTUDO DE CASO SOBRE COMÉRCIO ELETRÔNICO

JOSE GUILHERME DA SILVA SANTA ROSA 10 February 2006 (has links)
[pt] Esta pesquisa apresenta os conceitos do comércio eletrônico e busca o entendimento de como a preocupação com aspectos de usabilidade e da arquitetura da informação pode contribuir para uma experiência centrada no usuário, de modo a promover maior satisfação e aumentar as chances da conclusão da compra on-line. Para verificar a hipótese de que os aspectos de usabilidade de interface de formulários são determinantes do sucesso no preenchimento e na conclusão da venda on-line, foram selecionados os sites das Lojas Americanas, Casa e Vídeo, Ponto Frio e Submarino. Dentre os métodos e técnicas utilizados na pesquisa, destacam-se o focus group, cardsorting, teste de usabilidade e questionários de satisfação. O focus group foi utilizado nas fases iniciais da pesquisa para coletar informações sobre as motivações, crenças e atitudes dos usuários; em essência, o que os usuários diziam que pensavam. Utilizou-se o cardsorting para entender como os usuários compreendiam o sistema, através de exercícios pelos quais se verificava como eles agrupavam e rotulavam as informações solicitadas. Dessa forma, buscava-se captar não o que os usuários diziam pensar, mas sim o que pensavam. Os testes de usabilidade possibilitaram a observação e análise de como os usuários interagiam com o sistema. Verificou-se, portanto não o que os usuários diziam pensar nem o que pensavam, mas sim o que faziam. Os questionários de satisfação do usuário foram aplicados para coletar dados quantitativos, comentários e observações sobre atributos específicos da interação entre os usuários e os formulários de comércio eletrônico. Através das análises individuais e relacionais dos resultados dos métodos e técnicas, confirmou-se a hipótese de que os aspectos de usabilidade são determinantes do sucesso no preenchimento e na conclusão da compra on-line. Foram então apontadas diretrizes para a elaboração de formulários eletrônicos para conclusão de compra on-line na Internet. / [en] This research presents the concepts of electronic commerce and it searches the comprehension on how usability aspects and information architecture can contribute to an experience centered on the user that will promote a bigger satisfaction and will increase the chances of having an on- line purchase concluded. In order to verify the hypothesis that usability aspects of interface of forms are determinant on successful filling in and conclusion of on-line purchase, some sites as Lojas Americanas, Casa e Vídeo, Ponto Frio and Submarino were selected. Among the methods and techniques used in this work, it is necessary to distinguish focus group, card sorting, usability test and satisfaction questionnaires. Focus group was used in the initial phases of this research to collect information about users` motivations, beliefs and attitudes; in essence: what users have said they have thought. It was used card sorting to understand how users had understood the system, through some exercises by which was possible to verify how they have grouped and labeled the requested information. Thus, this work has searched to capture not what users have said they have thought, but what they have been thinking. Usability tests promoted the observation and analysis on how users have interacted with the system. Hence, it was possible to verify not what users have said or what they have thought, but what they had done. Users` satisfaction questionnaires were administered to collect quantitative data, commentaries and observation about some specific attributes of interaction between users and electronic commerce forms. By the agency of those relational and individual analyses of methods and techniques results, it was enabled to confirm the hypothesis that usability aspects are important on successful filling in and on the conclusion of on-line purchase. Thus, it was also possible to point out some directives to the elaboration of electronic forms to conclude on-line purchase in the Internet.

Implementace informačního modelu v prostředí systémové architektury / Information model implementation in systems architecture

Pořádek, Jiří January 2013 (has links)
This thesis deals with a field of information modeling and its relation to systems architecture. It is divided into two notional parts -- theoretical (first and second chapter) and practical (third and fourth chapter). First chapter explains the meaning of the term 'information model', compares it to the term 'data model' and then introduce its practical use in an enterprise modeling. It also defines the term of 'systems architecture' in its broad meaning and reduces it to three narrow meaning -- enterprise architecture, information architecture and information systems architecture, while it explains their relation to the information modeling. Finally this chapter provides the base for information model implementation methodology created later in the practical part of this thesis. Second chapter introduces architecture framework called TM Forum Frameworx specialized for a telecommunication services provider. It consists of three standards for business process, information and application architecture. The second one defines specific information model which is described partly in the second chapter and partly in the appendix B of this thesis. Third chapter describes the first of two contributions of this thesis - the information model implementation methodology. This methodology is applicable to any implementation of an information model. Three sections of this chapter contains diagrams and description of three phases of the methodology - pre-implementation phase, implementation phase and post-implementation phase. In the end of the chapter there is a table containing outputs of every single activity performed during all the phases. Fourth and last chapter then describes and evaluates real implementation of the information model from TM Forum Frameworx in the systems architecture department of an enterprise providing telecommunication services. This implementation based on the created methodology and its successful results then became the second contribution of this thesis.
