Gestão do design na prática : framework para implementação em empresas

Moreira, Bruna Ruschel January 2016 (has links)
O Design passou a ser executado em níveis cada vez mais complexos. No entanto, ainda existem desafios relacionados à inserção integrada das competências dos designers nas empresas, em virtude de uma visão fragmentada de muitas corporações acerca dos benefícios daquele. Por isso, a Gestão do Design ainda se assume como um desafio, quando se procura coordenar as práticas do Design de forma vertical nos níveis estratégico, tático e operacional. Nesse sentido, pesquisadores têm se detido em investigar sobre tal área, mas, de forma geral, os resultados restringem-se a contribuições mais teóricas do que aplicáveis em companhias. Dessa forma, a presente pesquisa visa apresentar um framework de Gestão do Design para aplicação em empresas desenvolvedoras de produtos. Para alcançar esse objetivo, foi necessário: compreender, sob uma perspectiva teórica e prática, os níveis de aplicação dessa gestão nas empresas, seus benefícios e desafios; identificar os fatores críticos de sucesso presentes na aplicação integrada do Design em companhias; explorar formas de realizar uma aplicação prática em empresas; analisar os elementos constitutivos de um framework conceitual e avaliar a aplicabilidade do framework. A fim de viabilizar tais discussões, a presente investigação foi delineada por meio de revisão bibliográfica, pesquisa de campo exploratória (composta pela opinião de noventa designers), Estudo de Caso (realizada com colaboradores e gestores de três empresas) e Pesquisa Ação (destinada a cinco empresas desenvolvedoras de produtos). Os resultados obtidos permitiram construir um framework de Gestão do Design, composto por oito etapas, que visam, respectivamente, pretender, engajar, estruturar e executar a inserção de práticas integradas do Design nas empresas. Cada etapa do framework apresenta, de forma clara, seu objetivo, as ações necessárias e os impactos organizacionais que tais atividades produzem na organização. Além disto, são recomendados alguns processos contínuos para a manutenção da inserção integral do Design nas companhias. / In the last decades, Design started being practiced in more complex levels. However, there are still challenges related to its vertical insertion due to a limited vision that many companies still have of its benefits. For this reason, Design Management is seen as a challenge since it aims to coordinate design practices in an integrated manner on strategic, tactical and operational levels. In this sense, many researchers have been investigating this area, but in general, the results are restricted to more theoretical contributions than applicable in companies. Thus, the present research presents a Design Management Framework for application in companies. To achieve this objective, it was necessary: to understand, from a theoretical and practical perspective, the application of this kind of management inside of companies, its benefits and challenges; identify the critical success factors present in application of design in companies; explore ways to achieve a practical application in companies; analyze the components of a conceptual framework and validate your applicability. In order to facilitate such discussions, this research was designed through a literature review, exploratory study (composed of the opinion of ninety designers), Case Study (conducted with employees and managers of three companies) and Research Action (aimed at five developers of companies). The results achieved enabled the construction of a framework composed by eight stages which aims to “intend, engage, structure and undertake” the insertion of integrated Design practices in companies. Each stage of the framework has the objective, the actions and the organizational impacts produced in the organization. Furthermore, some continuous processes are recommended for the maintenance of insertion of the Design in companies.

Utilização de serviços na integração de aplicações empresariais / Utilization of services in enterprise application integration

Kaneshima, Eliana 30 November 2012 (has links)
Atualmente a Integração de Aplicações Empresariais (EAI) desempenha um papel fundamental no cenário de integração de sistemas corporativos. Isso pode ser feito de diferentes formas, como por exemplo, por meio do compartilhamento de acesso às bases de dados ou trabalhando-se com Web Services, em que um serviço é disponibilizado por um sistema e pode ser chamado por outro sistema a ser integrado. Essas duas soluções estão sendo empregadas com sucesso, mas ambas apresentam vantagens e desvantagens que devem ser analisadas. Assim, este trabalho tem como objetivo primeiramente efetuar uma comparação entre essas duas abordagens de integração (tomando como base a norma ISO-IEC 9126-1) por meio de uma revisão bibliográfica complementada por uma revisão sistemática e relatos da experiência profissional da autora deste trabalho e da sua orientadora. Com o intuito de validar esta comparação, foi feito um estudo experimental, cujo objetivo do experimento foi avaliar a melhor abordagem para se realizar uma integração de aplicações empresariais: EAI-Dados e EAI-WS no que diz respeito ao esforço necessário para a implantação de cada uma. Assim, a avaliação foi realizada para responder à seguinte questão: Em termos de tempo de desenvolvimento e código produzido, é mais fácil realizar EAI-WS ou EAI-Dados? Finalmente, foram propostos cinco padrões para EAI, com o objetivo de auxiliar desenvolvedores com problemas similares de integração de aplicações. Esses padrões podem ser reusados em diversos contextos de integração, obedecendo às regras de negócios específicas a serem consideradas no momento da integração, e agilizando a modelagem da solução por meio da instanciação do padrão mais adequado a cada situação / Nowadays, Enterprise Applications Integration (EAI) performs a fundamental function in the scenery of enterprise systems integration. This can be done in different forms, for example by sharing the database access or working with Web Services, in which a service is provided by the system and can be called by other systems to be integrated. Those two solutions are being applied successfully, even though both present advantages and disadvantages that must be analyzed. Thus, the goal of this work is first to compare those two integration approaches, (Based on the standard ISO-IEC 9126-1) through a bibliographical review complemented by a systematic review and professional reports from the author of this work and her supervisor. In order to confirm this comparison, an experimental study was done, which resulted in quantitative answers about the best approach to perform systems integration: EAI-Data and EAI-WS which refer to effort required to deploy each. Thus, the assessment was conducted to answer the following question: In terms of development time and code produced, is easier to perform EAI-WS or EAI-Data? Finally, five patterns were proposed to EAI, which aim to support developers with similar problems of applications integration. These patterns can be reused in many integration contexts, following the rules of specific business to be considered in the moment of integration, and accelerating the modeling of the solution through the instantiation of the most adequate pattern to each situation

Caracterização da cobertura de pulverização necessária para controle do ácaro Brevipalpus phoenicis (G., 1939) em citrus /

Ferreira, Marcelo da Costa. January 2003 (has links)
Resumo: O objetivo desta pesquisa foi identificar a cobertura mínima necessária ao controle do ácaro Brevipalpus phoenicis. O trabalho foi conduzido no Depto. Fitossanidade - UNESP, Jaboticabal, em frutos de laranja infestados artificialmente com ácaros criados em câmara climatizada. Testou-se o efeito residual e tópico de propargite e verificou-se que o acaricida possui ambos os efeitos. Investigou-se o efeito da cobertura de frutos com pulverização da calda dos acaricidas: cyhexatin, óxido de fenbutatina, dinocap e propargite na concentração comercial e metade desta. Verificaram-se efeitos diferenciados, sendo a maior eficiência verificada para o cyhexatin e a maior migração dos ácaros da área tratada para o óxido de fenbutatina. Neste ensaio foi confirmado que quanto maior a área do fruto tratada maior a mortalidade dos ácaros. Determinou-se, então a cobertura mínima com base no tamanho e número de gotas a ser depositada para obtenção de controle satisfatório do ácaro. Utilizou-se o acaricida propargite nas concentrações de 0,036%, 0,072%, com e sem espalhante-adesionante e 0,144% sem espalhante-adesionante. Verificou-se que a adição do espalhante-adesionante prejudicou o efeito acaricida da calda. A cobertura mínima necessária para o controle do ácaro com a calda de propargite a 0,072% determinada no trabalho, foi resultante de 18 gotas de 293 æm por centímetro quadrado. / Abstract: The aim of this research work was to identify the minimum adequate spray coverage number and size to control the mite Brevipalpus phoenicis. The research was conducted at Department of Crop Protection - UNESP, Jaboticabal, using oranges artificially infested by mites reared in a controlled chamber. Residual and topical actions of propargite were tested and it was observed that the mitecide has both of effects. Effects of fruit coverage with spray of mitecides: cyhexatin, fenbutatin oxide, dinocap and propargite were investigated using the commercially recommended dosage rate and half of this dosage. It was verified that the effects varied being cyhexatin the most effective and fenbutatin oxide causing more escape of mites from treated area. In this trial was confirmed that larger the sprayed area higher was the mortality of mites. Minimum effective coverage was studied using 0.036% and 0.072% propargite solution, with and without spreader-sticker and 0.144% without the spreader-sticker. It was verified that addition of the spreader-sticker had detrimental effect on mitecide action. The minimum spray coverage to achieve control of the mite using 0.072% propargite solution determined in this work is 18 droplets of 293 æm per square centimeter. / Orientador: Tomassa Matuo / Coorientador: Carlos Amadeu Leite Oliveira / Banca: Hamilton Humberto Ramos / Banca: Casimiro Dias Gadanha Júnior / Banca: Ulisses Rocha Antuniassi / Banca: Carlos Gilberto Raetano / Doutor

Preparation of a hands-on tutorial teaching basics of Mainframe ISPF programming / Preparation of a hands-on tutorial teaching basics of Mainframe Assembler and ISPF programming

Vašák, Michal January 2010 (has links)
This paper is primarily focused on developers wanting to learn the essentials of developing mainframe applications on the IBM`s Interactive System Productivity Facility (ISPF) platform. It describes the components of the ISPF environment, focusing mainly on the two components most used in mainframe application development: The ISPF Dialog Manager and the ISPF Program Development Facility (PDF). Second part of the paper is a hands-on tutorial, where the reader is guided trough the creation of a set of simple interactive ISPF applications, with focus on covering the most used features of the platform. Within the paper it is assumed that any reader interested in this topic has basic mainframe skills and knowledge, including user knowledge of ISPF PDF, as it is usually the primary tool for dataset manipulation and editing in the z/OS mainframe environment. A wider skill set is assumed for readers who want to go through the tutorial, for example REXX and z/OS assembler basics. However none of these skills are necessary, nor expected, from those who are mainly interested in finding out what ISPF is and what it can offer to z/OS applications and their developers.

Influência de diferentes pontas de pulverização nas aplicações terrestres em alta velocidade na cultura da soja (Glycine Max) / Influence from different spray nozzles for ground applications using high travel speed in soybean crop (Glycine max)

Samir Elias Zaidan 16 December 2011 (has links)
O objetivo do trabalho foi o de comparar a eficiência de aplicação de agroquímicos na cultura da soja utilizando diferentes pontas de pulverização para aplicações terrestres em alta velocidade. Foram avaliadas as pontas AXI 110 04 na velocidade de 15 km.h-1 (testemunha), APE Cinza, AXI 110 08, TD Hispeed 110 06 e AXI TWIN 120 06, todos na velocidade de deslocamento de 35 km.h-1. O volume de aplicação foi fixado em 120 L.ha-1. A eficiência de aplicação foi avaliada por dois métodos: Análise do percentual de cobertura utilizando marcador fluorescente e luz ultravioleta e análise de depósito através da recuperação e quantificação do corante azul brilhante FD&C N°1 por espectrofotometria. Ambas as analises foram feitas em amostras retiradas de três partes da planta: Superior, média e inferior. As pontas de pulverização mostraram padrões de cobertura e depósito diferenciados, de modo que na parte superior da planta, a cobertura foi favorecida por gotas mais finas e o depósito melhorado pelo uso de gotas médias. Nas demais partes da planta não houve diferença estatística entre os tratamentos tanto para cobertura quanto para depósito. A velocidade de deslocamento não interferiu na eficiência de aplicação para pontas com mesmo padrão de gota, permitindo o aumento da capacidade efetiva do pulverizador sem diminuição na qualidade da aplicação. / The aim of this study was to compare the efficiency of agrochemical application on soybean crop using different types of spray nozzles for ground applications in high travel speed. It was evaluated the nozzles AXI 110 04 with ground speed of 15 km.h-1 (reference), APE Grey, AXI 110 08, TD Hispeed 110 06 and AXI TWIN 120 06, all using travel speed of 35 km.h-1. The volume rate was fixed in 120L.ha-1. The application efficiency was evaluated by two different methods: Analysis of coverage area using fluorescent dye tracer and UV light and analysis of deposits through the recovery and quantification of bright blue tracer FD&C N°1 by Spectrophotometry. Both analysis were done in samples collected from three parts of the plant: Top, medium and bottom. The spray nozzles showed differences in coverage and deposit pattern, so in the top of the plant, the coverage was increased with smaller droplets and the deposit was increased with medium droplets. In the other parts of the plant, there was no statistical difference between the treatments both for coverage and deposit. The travel speed did not influence the application efficiency for droplet with the same droplet pattern, so it is possible to increase the effective capacity of the sprayer without decreasing the application quality.

Developing, refining and feasibility study of mobile app to support asthma self-management (A4A - APP for Asthma)

Hui, Chi Yan January 2018 (has links)
Background: Self-management with an action plan, as opposed to passive self-monitoring, improves health outcomes. However, engaging patients is challenging. Mobile technology, incorporating education, personalised asthma action plans and facilitating professional support, is an option for supporting asthma self-management. Clinical research has focussed on health-related outcomes rather than informing the features that patients want and will use in a self-management app. Technology developers focus on user engagement as opposed to developing telehealth based on clinical evidence, leaving patients struggling to choose safe telehealth to support their asthma self-management. Risk aversion results in legislation that can be a barrier to the development of asthma apps. Aims and objectives: Using phases of the MRC Framework for developing complex interventions, and the Oxford app roadmap to develop a prototype app, I aimed, from clinical, patient, technology and legislative perspectives to: •(Phase 1) Identify the evidence base •(Phase 2) Model key aspects of app development •(Phase 3) Explore the feasibility of a mobile app to support self-management. Methods: •(Phase 1) Systematic review, online social forum analysis, asthma apps review, and legislation regulation review were used to identify evidence. Results were analysed with reference to the PRISMS taxonomy of self-management support. •(Phase 2) Using results from phase 1, and with the advice of lay and professional advisory groups, I made decisions about the design of the prototype app and the feasibility study in phase 3. I also reviewed the legislative issues regarding self-management app development. •(Phase 3) I undertook a feasibility study of using asthma mobile apps. Within the three-month feasibility study, five practices in Lothian/Oxford and Asthma UK's social media invited adults with active asthma to try out our prototype app. I observed patient's download rate and app usage. Of the patients recruited from practices, I purposively sampled patients (based on age/sex, experience of asthma, current self-management and technology use) and interviewed them before and after using the app for one month about their preferred features. Interviews were transcribed, and thematically analysed with reference to the PRISMS taxonomy of self-management support. Results: •(Phase 1) Telehealth was at least as effective as traditional approaches to supported self-management. Most asthma patients using online social forums commented on self-monitoring features, such as logging peak flow and symptoms, as opposed to self-management features. No one explicitly discussed asthma action plans though some patients were positive to the apps which had incorporated an action plan. Similarly the most downloaded asthma apps offered self-monitoring features rather than action plans. Current medical device legislation is ambiguous: it is unclear if apps with an action plan are 'medical devices'. •(Phase 2) The final prototype app included the Asthma UK asthma action plan and monitoring features such as the morbidity questions of the Royal College of Physicians three questions, peak flow, use of reliever inhaler, other medication use and lifestyle status. A mixed method approach was chosen for the feasibility study. •(Phase 3) 111 asthma patients used the prototype app. The ownership of action plans increased 43% to 63% after the study. Most patients preferred digital to paper action plans though the digital format did not improve usage. Action plans and monitoring features were the most 'wanted' features by patients, GPs, asthma nurses and the administration staff in the practices. Some patients also 'wanted' more advanced features such as predictive exacerbation warnings, identifying precise triggers, learning about what caused/affected their asthma. Conclusions: Mobile apps are a feasible option to support asthma self-management. Ease of access to download is the key to adoption as well as sufficient motivation (e.g. personal invitation from their GP or asthma nurse). Motivation (specifically GP and asthma nurse's encouragement and perception of benefit) is the key to adherence, but it will be more effective if the app is easy to use. Action plans and self-management features were the most 'wanted' features by patients and professionals. Other features that patients 'wanted' varied; one size does not fit all. Advanced features might encourage on-going use of asthma apps to support self-management. Choice of features, service promotion and service deployment should be considered carefully when implementing mobile app in 'real world' setting. The key technological barriers were to provide seamless Wi-Fi and to connect the app with the practice's software platforms. 'Medical device' legislation is currently a barrier for self-management app development, further discussions with all stakeholders is needed to reach consensus on risks involved in incorporating action plans in an app.
