Philosophiae Doctor - PhD / Since 1994, the District Six Museum, in constructing histories of forced removals from District Six, Cape Town, commenced as a post-apartheid memory project which evolved into a memorial museum. Design has been a central strategy claimed by the museum in its process of making memory work visible to its attendant publics evolving into a South African cultural brand. Co-design within the museum is aesthetically infused with sensitively curated exhibitions and a form of museumisation, across two tangible sites of engagement, which imparts a unique visual language. The term design became extraordinarily popular in contemporary Cape Town, where the city was - in 2014 -the World Design Capital. Yet at the same time as design was being inscribed into the public imaginary, it was simultaneously curiously undefined although influential in shifting representational aesthetics in the city. This research seeks to ask questions about this proliferation of interest in design and to examine this through a close reading of the work of the District Six Museum situated near District Six. In particular, micro and macro design elements are explored as socio-cultural practice in re-imagining community in the city that grew out of resistance and cultural networks. Various design strategies or frameworks of representation sought to stabilize and clarify individual and collective pasts enabling and supporting ex-residents to reinterpret space after loss, displacement and separation and re-enter their histories and the city. Post-apartheid museum design modes and methodologies applied by the District Six Museum as museumisation disrupts conventional historiographies in the fields of art, architectural and exhibition design, where the focus is placed on temporal chronologies, in a biographic mode profiling examples of works and designers/artists. Instead, the research contextualises the work of design as making in a more open sense, of exploring the very constructedness of the museum as a space of method, selection, process and representation thereby asking questions about this reified term design as method and practice. The designing ways of the District Six Museum contribute to understanding idioms mediated through design frameworks allowing for a departure from the limited ways design history has been written. Through an unlayering of projects, practices and an examination of archival case studies, exhibition curation, the adaptive reuse of buildings and through institutional rebranding my argument is that the particularities of the claims to design work at the District Six Museum provide a rich case for relating to other contemporaneous processes of making apartheid’s spatial practices visible as projects such as this claim community. Therefore seeking to demystify how this community museum ‘making’ has been fashioned through an investment in various design disciplines, forms and practices revealing the inherent complexity in doing so.

Design for Six Sigma (DFSS) is a further development of the Six Sigma draft to carry through preventing quality measures in developing and designing of new products and processes. With increasing demands on enterprises development processes to be more safety and faster the need of DFSS arise as a product, process and service development concept in the organisations. Design for Six Sigma aims to improve and structure the development process of an organisation and consider the application of the innovation problem solving. The concept aims to leave the structure of the traditional Six Sigma concept and instead, from an innovative perspective, search for new solutions to existing problems. The concept constitute of a toolbox with a lot of quality tools that are divided into phases in a development model. Combined with the organizations project model the Design for Six Sigma concept can give rise to excellent results in the work with developing and designing of new products and processes. The condition to succeed is that the draft has been established and accepted with the organizations collaborator. This thesis work summarizes the contents of the Design for Six Sigma concept. The concentration of the performance has been the underlying theory behind the DFSS draft together with the contents of the methodology and the included tools. / Design for Six Sigma (DFSS) är en vidareutveckling av Sex Sigma-konceptet för att genomföra förebyggande kvalitetsåtgärder vid ny- och vidareutveckling av produkter och processer. Med ökade krav på säkrare och snabbare utvecklingsprocesser hos organisationer uppkommer ett behov av detta produkt-, process- och tjänsteutvecklingskoncept. Design for Six Sigma konceptet behandlar strukturering och utveckling av en verksamhets utvecklingsprocess och handlar mycket om applicerandet av det som vanligen benämns innovativ problemlösning. Konceptet syftar således till att frångå Sex Sigmas traditionella strukturerade arbetssätt och istället, utifrån ett innovativt angreppssätt, söka fastställa helt nya lösningar på ett problem. Konceptet består av en verktygslåda med kvalitetsverktyg uppdelade i faser i en utvecklingsmodell. Kombinerat med en organisations projektledningsmodell kan Design for Six Sigma medföra goda resultat vid produkt och processutvecklingsarbete under förutsättning att förståelse och acceptans hos medarbetarna etablerats. Detta examensarbete sammanfattar innehållet i Design for Six Sigma-konceptet. Fokus har legat på DFSSs bakomvarande teorier vilka utgör grunderna till konceptet samt dess innehåll och verktygslåda.

The modern manufacturing world has been driven to compete in a more international and interconnected system. This has led to increased focus upon frameworks and architectures to guarantee quality, high market acceptance, and reduce cost. Modern manufacturing design processes evolved largely from Henry Ford at Ford Motor Company, and Alfred Sloan at General Motors. Their structures embody two different focuses on quality and value engineering which have influenced many recent design frameworks. In the 1970s a heavy emphasis was placed upon Design for Manufacturing, which uses group technology, commonality of processes, and continual focus to reduce part count. Some companies have desired a design process that better accounts for new market needs and Voice of the Customer changes, allowing them to break out of the old processes by using a new framework called Design for Six Sigma. Contextual and survey analysis contrasting DFSS and DFM showed these systems have different definitions of what creates value; which causes a different focus on how to improve value. As the market frequently errs at knowing when to apply DFM or DFSS, using a simple case study of a product with high part and assembly cost, teams were challenged to create a better flashlight using both DFM for part reduction, and DFSS for function improvement. The aim was to increase value. Value has been defined by the formula: value = (performance + capability) / cost or as value = function/cost. Results from the case study combining DFM and DFSS constructs demonstrate a total value engineering construct. It was also shown that DFM indicated effectiveness for a slow-changing market with cost reduction focus, and DFSS demonstrated effectiveness for analyzing continually changing market needs. Disruptive innovations can replace a formerly lull market, for which DFM can be completely unprepared; while DFSS is not effective in slow product-change markets. Incorporating the best of DFSS and DFM creates a Total Value Engineering framework.

A competitividade é um fator de extrema importância para o sucesso das organizações. Os expressivos resultados alcançados pela Motorola e General Electric (GE), por meio do programa Seis Sigma, tem sido uma fonte de inspiração para muitas empresas seguirem o seu exemplo e conseguir maior competitividade. O programa Seis Sigma foi criado e evoluiu em ambiente de manufatura, mas também pode ser aplicado em processos de serviços. Entretanto a aplicação em serviços tem sido feita de forma mais modesta, com menor participação de empresas, e conseqüentemente menor número de casos e relatos divulgados. A literatura menciona que de forma geral o desempenho dos processos de serviços é inferior aos processos de manufatura, e isso pode ser um indicativo de boa oportunidade para a aplicação do programa Seis Sigma. Este trabalho tem como objetivo a análise comparativa da aplicação do programa Seis Sigma em processos de manufatura e serviços, por meio de revisão da literatura e pesquisa com empresas que aplicam o programa, visando entender as diferenças da aplicação em benefício da aplicação em serviços. Os resultados obtidos sugerem indícios de similaridades e diferenças significativas, tais como \"no perfil do Black Belt, nas equipes de projeto, no tempo de execução de um projeto, no uso da CTQ, na disponibilidade e natureza dos dados e na aplicação de técnicas e ferramentas\" que podem ajudar na expansão do programa em serviços, e assim, espera-se que possa motivar mais pesquisas com esse tema de trabalho. / Competitiveness is an important factor for any organization success. The Six Sigma program, which has been used by companies like Motorola and GE since the 1980\'s, has proved to be a successful way to make any company improve all areas of business and therefore, become more competitive. Although it was created and has been growing in manufacturing successfully, its implementation can reach a much wider field of application. In the last few years, some service corporations also been benefited by the use of this program. However, different from manufacturing, its application is less popular and still restricted to few companies that have already implemented it, which explains limited case studies and projects published in the literature. This paper has the goal to perform a comparative analysis of Six Sigma program implementation in manufacturing as well as in services process and consequently, comprehend the differences and advantages of its application in these different fields. The results of this study, which are based on literature review and also a survey with service companies, have led to some significant similarities and differences like the profile of the Black Belt, project time execution, CTQ use, the nature and availability of the data and application of techniques and tools. Further research, can certainly contribute to the expansion of the Six Sigma methodology improvement in service quality.

L'objectif de cette thèse est d'étudier la politique de la Grande-Bretagne vis-à-vis du conflit israélo-arabe au prisme de ses intérêts au Proche-Orient entre la première guerre israélo-arabe (1948-1949) jusqu'à la guerre des Six-Jours en 1967. Nous avons essayé de préciser, en ce sens, qu'en plus des intérêts politiques, géostratégiques et économiques, cette politique a été aussi marquée par les changements des rapports de force qui s'imposaient inévitablement dans le monde entier, notamment l'avènement des États-Unis et de l'URSS comme superpuissances mondiales, le nationalisme arabe…etc. Dans ce cadre d'intérêts politiques et économiques, nous avons souligné que la création de l'État d'Israël répondait aux besoins stratégiques des puissances occidentales au Moyen-Orient. D'ailleurs, cette approche prouvera sa validité dès 1956 quand l'État d'Israël va jouer un rôle déterminant pendant l'expédition de Suez. Nous avons mis l'accent sur la place qu'occupait l'industrie du pétrole et les intérêts commerciaux dans le processus de la décolonisation britannique du Moyen-Orient pendant les années 1950 et 1960. Bien que l'étude de la politique britannique au Proche-Orient soit négligée, et ce, en raison de son « déclassement politique », notre recherche a bien montré que la Grande-Bretagne a joué un rôle aussi important que celui des Américains dans la sauvegarde de leurs intérêts à travers une « gestion » commune des affaires du Moyen-Orient. / The aim of this thesis is to study the British policy towards the Arab-Israeli conflict through the prism of British interests in the Middle East from the first Arab-Israeli war in 1948-1949 to the Six-Day War in 1967. In addition to economic and political interests, we show that in the years under review the British policy has also been marked by a change in the world balance of power, namely the emergence of the United States and the Soviet Union as the world's leading superpowers, Arab nationalism ... etc. In this context, we emphasize that the creation of the State of Israel met the strategic needs of Western powers in the Middle East. This approach will prove its effectiveness only eight years after the creation of Israel when the latter played a decisive role during the tripartite invasion of Egypt in late 1956. Moreover, we point out the place occupied by oil industry and commercial interests in the process of British decolonization in the Middle East in the 1950s and 1960s. The study of British foreign policy in the Middle East has been neglected because of the “demise of Britain's political supremacy” worldwide. Nevertheless, we show that Britain has played a role as important as that of the United States in safeguarding their common interests in the Middle East through a close collaboration.

All manufacturing requires some form of quality control to be able to ensure that a product will meet the customers requirements. Volvo Construction Equipment AB has a TDI station, Test Delivery Inspection, for transmissions. They experience a lack of insight and knowledge of the tests that has been done and therefore the purpose of this project is to investigate and improve Volvo CE's test equipment for transmissions and its reliability. The aim is to provide improvement proposals to the organization as well as a plan for the implementation, follow-up and control of the process. The study is an improvement project and therefore the methodology Six Sigma and parts of the work process DMAIC are used to accomplish the study. The method is adapted for improvement projects and is primarily used by larger producing companies. For data collection, both quantitative and qualitative methods are used. These methods are; the use of existing data from the organization, brainstorming and two different MSA tests aimed at examining the machine and the human's influence on the process. Several quality tools were helpful when analyzing the results and the two factors that has the biggest impact on the test equipment's results is the impact from the human and the test equipment itself such as the variation of the test equipment. An initial approach to reducing the impact of these factors and thereby making the test equipment more reliable is to make sure that all routines are followed and ensure that the method for extracting data from the test equipment is right. The conclusions are that the tolerance limits needs to be checked again just because they are based on personal experience and the process can be controlled with statistical process control. To follow up on the results, the same tests can be performed repeatedly and compared with this project. The project can be described as a standardized working method for similar improvement projects and can also be applied to other processes. / I all tillverkning krävs någon form av kvalitetskontroll för att kunna säkerställa att en produkt infriar kundernas krav. Volvo Construction Equipment AB har en TDI-station, Test Delivery Inspection, för färdigmonterade transmissioner och upplever en bristande insikt och kunskap om de tester som genomförs. Syftet med detta projekt är att undersöka och förbättra Volvo CE:s testutrustning för transmissioner och dess tillförlitlighet med målet att ge förbättringsförslag till organisationen samt en plan för genomförande, uppföljning och styrning av processen. Projektet är ett förbättringsprojekt och därför används metodiken Six Sigma och delar av arbetssättet DMAIC för att genomföra studien. Metoden är anpassad till förbättringsprojekt och används i första hand av större producerande företag. För datainsamlingen används både kvantitativa och kvalititativa metoder. Dessa metoder är; använding av befintlig data från organisationen, brainstorming samt två olika MSA-tester som syftade till att undersöka maskinens samt människans påverkan på processen. Ett flertal kvalitetsverktyg var till hjälp i analyserandet av resultatet. De två största påverkansfaktorerna på testutrustningens resultat är människan och maskinen. Ett första angreppssätt för att minska dessa faktorers påverkan och på så sätt göra testutrustningen mer tillförlitlig är att se till att alla rutiner följs samt att säkerställa metoden för att ta ut värden från testutrustningen. Processen kan styras med hjälp av statistisk processtyrning där resultatet även visar på att toleransgränserna bör ses över då de är satta utifrån erfarenhet. För att följa upp resultatet kan samma tester genomföras upprepade gånger och jämföras med detta projekt. Projektet kan berskrivas som ett standardiserat arbetssätt eller en metod för genomförande av liknande förbättringsprojekt och kan appliceras på andra processer.

INTRODUÇÃO: A doença pulmonar obstrutiva crônica (DPOC) apresenta obstrução crônica ao fluxo aéreo e evolui com perda da capacidade funcional. A intolerância ao exercício é um marcador prognóstico da doença. OBJETIVO: Investigar as respostas fisiológicas no teste incremental com cicloergômetro (TECP), teste do degrau de 6 minutos (TD6), teste da caminhada de 6 minutos (TC6) e teste senta e levanta de um minuto (TSL) em pacientes com DPOC. MÉTODOS: Foram incluídos 24 pacientes com DPOC (VEF1/CVF<70 e VEF1 pós bd <80%), clinicamente estáveis. Todos os pacientes realizaram provas de função pulmonar e os quatro protocolos de exercício. Durante os testes foram medidos: consumo de oxigênio (VO2), produção de CO2 (VCO2), ventilação (VE), frequência cardíaca (FC), frequência respiratória (FR), oximetria de pulso (SpO2), e sensação de dispneia e de desconforto nas pernas (escala de BORG modificada). RESULTADOS: Quinze pacientes eram homens, a média de idade foi de 63,7 ± 6,6 anos e do VEF1 foi de 1,20 ± 0,60 L, 42,5 ± 17,8 % do predito. O VO2pico observado no TD6 (1,01±0,40 L.min-1) não diferiu do VO2 medido no TECP (0,86±0,32 L.min-1) e no TC6 (0,99±0,46; L.min-1;p>0,05). Entretanto, o VO2 pico do TSL foi significativamente inferior (0,66±0,32 L.min-1, p<0,05). A VE foi comparável no TECP, TD6 e TC6. O estresse cardiovascular foi mais intenso no TECP, porém o pulso de oxigênio (VO2/FC) foi inferior no TECP e no TSL. Dessaturação (queda da SpO2 ³4% e SpO2 £88%) foi mais frequente no TC6 e no TD6. Dispneia e desconforto em pernas foram mais intensos no TECP. No TD6 14 pacientes interromperam o teste e no TC6 um paciente interrompeu. CONCLUSÕES: A dessaturação durante o exercício foi mais evidente no TD6 e no TC6 e estes testes reproduziram respostas fisiológicas equivalentes às do TECP. / BACKGROUND: Chronic obstructive pulmonary disease (COPD) has chronic obstruction of airflow and loss of functional capacity. Exercise intolerance is a prognostic marker of the disease. OBJECTIVE: To investigate the physiological responses to incremental cycle ergometry (CPET), six-minute step test (SMST), sixminute walk test (SMWT), and one-minute sit-to-stand test (STST) in patients with COPD. METHODS: We included 24 patients with COPD (FEV1/FVC ratio <70 and FEV1 post bd <80%), stable. All patients underwent pulmonary function tests and the four exercise protocols. Peak oxygen uptake (VO2peak), CO2 production (VCO2), ventilation (VE), heart rate (HR), respiratory rate (RR), pulse oximetry (SpO2), dyspnea and leg disconfort (modified Borg scale) were measured during the tests. RESULTS: Fifteen patients were men, mean age was 63.7 ± 6.6 years and FEV1 was 1.20 ± 0.60 L, 42.5 ± 17.8 % predicted. VO2 peak in SMST (1.01±0.40 L.min-1), measured during CPET (0.86±0.32 L.min-1) or SMWT (0.99±0.46; L.min-1) was not different (p>0.05). However, peak VO2 of STST was lower (0.66±0.32 L.min-1, p<0.05). VE was comparable among CPET, SMST and SMWT. The cardiovascular stress was more intense during CPET and oxygen pulse (VO2/HR) was lower during CPET and STST. Desaturation (decrease of SpO2 ³4% and SpO2 £88%) was more frequent during SMWT and STST. Dyspnea and leg disconfort were higher on CPET. The SMST was interrupted by 14 patients and the SMWT by one. CONCLUSIONS: Desaturation during exercise was more evident on SMWT and SMST and these tests elicited similar physiological responses as the CPET.
