Det här examensarbetet består av en livscykelanalys av en styrsystem. Genom den studien har man försökt att fokusera och ta reda på hur en styrsystem kan påverka miljön genom sin livs längd. Alla faktorer som koldioxid utsläpp, energi-och material använding samt hur mycket detta påverkar miljön har studerats. Eftersom Livscykelanalysen brukar vara tidskrävande och detaljrat, har en enklare metod för snabbare result och analys av styrsystem valts. Den här metoden kallas för fast track LCA, det är en mindre komplicerad metod. Motivationen bakom denna studie är resurshushållning och energieffektivitet. Resultatet från denna analys skall användas för vidareutveckling av hydrualiska styrsystem, vilket skulle kunna ge möjlighet till en förbättring i de nya modellen av styrsystemet. Denna utveckling är tänkt att ske i miljövänlighets syfte. I det avslutande kapitlet tolkas och presenteras resultaten i tabeller och figurer. Baserat på dessa tolkningar kommer resultaten och utvecklingsmöjligheter att diskuterass ytterligare.Utifrån dem dras slutsatsen samt förbättringar från mijösynpunkten föreslås.
This thesis work mainly contains a fast track Life Cycle Assessment (LCA) study of a hydraulic steering gear. The study gives a picture of the hydraulic steering gear through its complete Lifecycle from an environmental point of view. The main motivations behind this study are natural resources conservation and energy efficiency. According to ISO 14040 and 14044 LCA is a complex and time consuming method, the chosen approach for LCA in this study is the Fast Track LCA. The Fast Track LCA gives results which are equally accurate and still could be achieved by taking a shorter way and applying an easier and less complicated method. The intended application of this study is to use the results for further development of the new hydraulic steering gear design, in comparison to the current one. These developments are supposed to be more environmentally friendly. In the final chapter, the findings are interpreted in tables and figures, based on these interpretations the findings are discussed further and the environmentally improvements are suggested and the conclusions are drawn.

Annotation:

This study examines the use of one finishing electrode to finish multiple dies without remachining the electrode. The multiple-use electrode finishing experiment in this study addresses technology in the die-forging industry. Methods of manufacturing spherical straight bevel forge gear dies have relied on die-sinking Electrical Discharge Machining (EDM) practices that showed great potential for advancement. The focus of this study is solely on the improvements of electrode use in EDM finishing-processes. The surface finish quality itself is not an area of concern other than maintaining that it does not diminish. The focused concern is maximizing the process by using one electrode unmodified for multiple-finishing operations. The objective for improvement is utilization of one finishing electrode used multiple times rather than only one finishing electrode per die. Utilizing a Coordinate Measuring Machine (CMM), the inspection of specific locations on the finishing electrode reveals the repeatability and accuracy of use for one finishing electrode for six gear forging-dies. Initial experimentation validates the capabilities to finish four dies accurately in two separate die configurations with one electrode. To accomplish finishing the four initial dies, a die-sinking EDM machine that possesses a large enough working envelope was included in the process. The transition of using graphite electrode materials in place of brass for finishing multiple dies aids in reducing what was a total eight-hour process time into a four-hour process time.A machine with a working envelope large enough for only setting up one die to be EDM machined generated the eight-hour process time. The researcher achieved the eight-hour process time by replacing brass electrodes in the roughing stages with graphite electrodes. The extent to which one finish electrode can finish a sample set of six complete dies with one electrode is studied. Data is extrapolated from the deviation of absolute locations on a three-dimensional solid model compared to the multiple-use finishing electrode. Specific locations inspected on the electrode conclude the study efforts with results revealing that the maximum repeated use of an electrode is seven uses.

The research establishes a methodology for developing Web-based CAD/CAM software systems to industrial quality standards in a time and cost e ective manner. The methodology de nes the scope of applicability, outlines major considerations and key principles to follow when developing this kind of software, describes an approach to requirements elicitation, resource allocation and collaboration, establishes strategies for overcoming uncertainty and describes the design concerns for industrial Web-based CAD/CAM systems. The crucial parts of the methodology are a novel project development model facilitating architecture optimisation early in the project to minimise total development e orts, create future-proof solutions and ensure system maintainability; and a novel approach for planning based on time reserve management and task prioritisation, which provides the exibility required for exploratory development while maintaining the main focus on project objectives. The e ectiveness of the Web-based CAD/CAM software development methodology has been examined using two real software development case studies: a Web-based CAD/CAM system for involute spur gear shaper cutters and a Web-based CNC code editor for online modi cation of the pro le for manufacturing gear shaper cutters. The development of case studies using the established methodology resulted in on-time delivery of two industrial browser-based CAD/CAM systems, that produce valid results, embrace all business processes associated with the application area, ensure all functional and non-functional requirements and are used in production now. The developed software products demonstrate robustness, performance, reliability, security and usability comparable with the standards of modern commercial software, utilise advantages of Web-based applications to the highest extent and con rm advantages of Web-based CAD/CAM software compared to similar desktop applications. E ectiveness of the proposed methodology for Web-based CAD/CAM software development was checked through validation, evaluation and analysis of case study results.

This thesis deals with the conceptual design of a double clutch gearbox and the inspection of selected designed parts of this gearbox. The first part of the thesis is focused on the theory of automotive transmissions and analysis of already available double clutch gearboxes. The following is the conceptual design itself, which is based on the selected vehicle on which the transmission will be located and on driving resistances. Based on these default values, the gear graduation is selected, which affects the vehicle’s driving dynamics. With regard to the installation space, a conceptual arrangement of the gearbox is proposed. Furthermore, the thesis is focused on the basic design and calculations of individual functional components of the gearbox. The last part of the thesis is involved to the control of selected structural nodes using the finite element method in the ansys workbench software. The whole thesis describes the individual steps for the design of the basic concept of a double clutch gearbox and the design of their basic components.

Annotation:

The key debates after apartheid have been on the successes and shortcomings of the social and economic policies that were adopted after apartheid. The ANC government decided to approach poverty reduction by closing the inequality gap between racial groups in the country. It planned to provide services that would improve the poor people’s lives and also create employment to sustain development. To provide the necessary services, the government formulated two broad, but linked macroeconomic policies namely: the RDP and GEAR which focused on the demand and supply side respectively (Venter and Landsberg (2006). This indicated the importance with which the people’s welfare and growth were regarded by the South African government. It indicated that the government believed in pro-poor growth. The purpose of this study was to gain better and deeper understanding about poverty reduction since the 1994 political transition, from the poor people of Airport Valley (in the Nelson Mandela Metropolital Municipality), who experience poverty from the real world. The study attempted to find out from these people if there was improvement in their lives since democratisation. This qualitative and quantitative study used three methods of collecting data namely: a questionnaire, interviews and observation. The results of the study suggest that there has been lack of commitment by RDP and GEAR, as the conditions under which the people live and therefore their standard of living have not improved. The study recommends that the government should speed up the process of service delivery at Airport Valley and also include the people in decision making about the future of Airport Valley.

While the American dream could have different meanings for Americans today, one dream for many middle and high school students is to have the opportunity to attend college; however, a challenge facing students across the United States is that they are graduating from middle and high school unprepared to enter the postsecondary institution of their choice. Despite over thirty years of educational reform attempts since “A Nation at Risk” (1983) was published, there continues to be a growing concern that middle and high school graduates are not college and career ready (Choy, Horn, Nunez, & Chen, 2000; Conley, 2010; Jackson, 2009). Consequently, middle and high school students deemed college-eligible are often not college-ready. Students who are not in the top academic quartile in middle and high school may have aspirations of attending college, but often fail college entrance exams (Leonard, 2013). They contend that middle and high school graduation course requirements are often less than rigorous, or misaligned with courses necessary for college admission. Due to the lack of early academic preparation, students may need to take remedial courses once in college (Adelman, 1999). Public universities across the United States invest billions of dollars remediating about one-third of their incoming freshman, which in turn costs students more time and money (Bettinger & Long, 2009; Wimberly & Noeth, 2005). This study explores the fundamental distinctions of college readiness through the examination of a grant project received under the federal college-ready program, Gaining Early Awareness and Readiness for Undergraduate Programs (GEAR UP). The study could reveal important information, which may bring about necessary changes in middle and high schools. By investigating how GEAR UP students describe their experiences with the project, as well as how these experiences contribute to college readiness, student voices and stories may benefit policymakers and administrators as they plan for academic and social supports for future middle and high school students.

In all common hydrostatic pumps, compressibility affects the commutation phases of the displacing chambers, as they switch their connection from/to the inlet to/from the outlet port, leading to pressure peaks, localized cavitation, additional port flow fluctuations and volumetric efficiency reduction. In common pumps, these effects are reduced by proper grooves that realizes gradual port area variation in proximity of these transition regions. This paper presents a method to automatically find the optimal designs of these grooves, taking as reference the case of external gear pumps. The proposed procedure does not assume a specific geometric morphology for the grooves, and it determines the best feasible designs through a multi-objective optimization procedure. A commercial gear pump is used to experimentally demonstrate the potentials of the proposed method, for a particular case aimed at reducing delivery flow oscillations.

Annotation:

Hardening distortions are unwanted changes in shape and dimension that arise during hardening of steel components. Uncontrolled distortions induce random errors to the manufacturing process, and have a strong negative impact on manufacturing costs. The distortions are not only caused by the hardening process, several factors from previous manufacturing steps including the component geometry itself contribute to varying extent. The aim of the current work is to investigate the main influencing factors on hardening distortions for serial produced gears. The investigations were done on two different types of gears for heavy-duty transmissions, crown wheels for the rear axle central gear and main shaft gears for the gearbox. The steel was produced using either continuous casting or ingot casting. For rectangular continuously cast steel, the effect of disabling magnetic stirring of the steel melt during casting was investigated, finding a strong reduction of gear runout for crown wheels. Segregations in crown wheels produced from the top and bottom of ingots were shown to go in opposite directions, producing opposite back-face tilts. For crown wheels quenched one at a time, influences of stacking level on the hardening tray were found, indicating an impact from small variations in the carburizing process, despite identical quenching conditions. For main shaft gears, horizontal loading gave considerably less roundness and runout errors but increased flatness errors compared to vertical loading. This thesis shows the complexity of the distortion phenomenon and how several factors interact and contribute to the final result. It is shown that factors with significant impact on hardening distortions for one component may be less important for another component. With this in mind, each type of component to be hardened should be produced by a manufacturing chain where each process step is carefully chosen with respect to minimizing distortions.

Climate change is a rising concern worldwide. One of United Nations’ (UN) 17 sustainable development goals is Goal 12: Responsible consumption and production which states that developed countries take the lead on showing the path for substantially reducing waste generation through prevention, reduction, recycling, and reuse (UN, 2015). With the goal in mind, it is important for countries like Sweden to navigate towards a more sustainable world. This is especially relevant for fast growing industries such as gaming and esport. As gaming grows, consumption of gaming gear such as mice and keyboard increase multifold since these peripherals are consumption products with constant performance updates. The purpose with this paper is to understand gamers awareness regarding recycling and how they view sustainability and recycling options of their gaming gear, specifically gaming mice, and keyboards. This paper also aims to understand what options consumers must contribute to less e-waste. The method of choice in this paper to better understand gamers perspective has been with qualitative research and an abductive approach. The gamers who answered the survey were found in Discord communities where they varied in both age and how often they play – from hobby gamers to professional. The results, from 40 gamers in Sweden, show that gamers today do not rely much on price or sustainability factors when purchasing their gaming gear. Non-functional gaming gear is often immediately disposed of with no consideration of recycling. A proposal in this paper is for producers to improve their communication with consumers to increase consumers sustainability awareness, or an e-waste management system brought forward by Swedish initiatives similar to the system of recycling drinking bottles. In conclusion, this paper contributed to literature by setting ground for future studies of how to increase awareness to generate more sustainable conscious consumers in emerging markets. At the same time, this paper provides ideas of how businesses and producers can improve their Corporate Social Responsibility (CSR) by helping to create more consumer awareness to minimize products environmental impact.
Klimatförändringar är en växande oro över hela världen. En av Förenade Nationernas (FN) 17 mål för hållbar utveckling är mål 12: Ansvarsfull konsumtion och produktion som menar att utvecklade länder bör ta ledningen för att visa vägen för att avsevärt minska avfallsproduktionen genom förebyggande, minskning, återvinning och återanvändning (UN,2015). Med målet i åtanke är det viktigt för länder som Sverige att styra mot en mer hållbar värld. Detta är särskilt relevant för snabbt växande industrier som spel och esport. När spel växer ökar konsumtionen av spelutrustning som möss och tangentbord hastigt eftersom dessa är konsumtionsprodukter med konstanta prestandauppdateringar. Syftet med denna uppsats är att förstå hur medvetna spelare om återvinning och hur dessa ser på hållbarhets- och återvinningsalternativ för deras spelutrustning, särskilt spelmöss och tangentbord. Denna uppsats syftar också till att förstå vilka alternativ konsumenterna måste bidra med för mindre e-avfall. Metoden som valts i denna uppsats för att bättre förstå spelarnas perspektiv har varit med kvalitativ forskning och ett abduktivt synsätt. Spelarna som svarade på enkäten hittades på Discord grupper och varierade i både ålder och hur ofta de spelade – från hobby till proffs spelare. Resultatet, från 40 spelare i Sverige, visar att spelare idag inte bryr sig mycket om pris- eller hållbarhetsfaktorer när de köper spelutrustning. Icke-funktionell spelutrustning kasseras ofta omedelbart utan hänsyn till återvinning. Ett förslag i den här uppsatsen är att producenter ska förbättra sin kommunikation med konsumenter för att öka konsumternas återvinningsmedvetenhet, eller ett e-avfallshanteringssystem som tagits fram av svenska initiativ liktsystemet för återvinning av dricksflaskor. Avslutningsvis bidrog denna uppsats till litteratur genom att lägga grunden för framtida studierav hur man kan öka medvetenheten för att alstra hållbara medvetna konsumenter i tillväxtmarknader. Samtidigt ger denna uppsats idéer om hur företag och producenter kan förbättra sitt företags sociala ansvar genom att hjälpa till att skapa mer konsumentmedvetenhet för att minimera produkters miljöpåverkan.

Micropitting is a form of surface contact fatigue encounteredin bearingsa nd gears, under lubricating conditions, which lead to their premature failure. All gears are susceptible to micropitting, including spur, helical and bevel. Micropitting can occur with all heatt reatmentsa ppliedt o gearsa nd with both, synthetica nd mineral lubricants. It can occur after a relatively short period of operation and, after a certain number of cycles,g earsn eedt o be replacedd ue to the increasedn oisea nd vibrations causedb y the deviations of the tooth profile. Continuing operation of affected gears can lead to a catastrophic type of failure (i. e., tooth breakage). These considerations explain the increasing current interest in micropitting. It has been reported that micropitting in bearings is associated with a specific microstructural transformation in steel, i. e. martensite decay. However, to the authoes knowledge, this transformation has not been reported in gears. In the present work, extensive metallurgical investigations have been carried out and they revealed that the same transformation occurs in gears. The aim of this project was to describe the mechanism of micropitting by taking into account the influence of several controlling factors such as, material, surface finish, lubricant, load, temperature,s peeda nd, slide-to-roll ratio.

Annotation:

The optimization of case hardening depth for small gears was investigated with the use of Abaqus and the subroutine DANTE to simulate the formation of the microstructural phases, resulting in residual stresses and increased hardness. This was done with a step wise increment of the carburizing time, resulting in a theoretical maximum for compressive residual stresses at the surface. The heat treatment parameters were then used for case hardening two gears with different carburizing times. The heat treated gears were then tested for tooth root bending fatigue. The fatigue testing resulted in a fatigue limit increase, where the gear with largest simulated compressive stress showed the highest fatigue limit. Both the heat treated gears were hardness tested and compared with the conducted simulations resulting in an underestimated hardness. An investigation to see whenever the simulations could predict the fatigue outcome beforehand with a probabilistic model was put into place. This resulted in an underestimated fatigue limit in relation to the raw fatigue data.
Optimering av sätthärdningsdjup för små kugghjul undersöktes med Abaqus och subrutinen DANTE, för att simulera uppkomsten av de mikrostrukturella faserna som resulterar i restspänningar. Detta genomfördes med en stegvis ökning av uppkolningstiden som resulterade i ett teoretiskt maximum för tryckspänningar i ytan. Härdningsparametrarna användes sedan för att sätthärda två serier med kugghjul med olika uppkolningstid. Båda kugghjulen testades sedan för kuggrotsböjning med avseende på utmattning. Utmattningsprovningen resulterade i en ökning av utmattningsgränsen, där kugghjulet med de största simulerade tryckspänningarna resulterade i den högsta utmattningsgränsen. De härdade kugghjulen hårdhetstestades och jämfördes med genomförda simuleringar, vilket resulterade i en underskattad hårdhet. En undersökning för att se om det är möjligt att prediktera resultatet för en serie utmattningstester via en sannolikhetsmodell användes. Detta resulterade i ett lägre resultat gentemot de genomförda utmattningstesterna.

Bakgrund: Kommunikation mellan personal inom hälso- och sjukvården är viktiga faktorer för att kunna garantera patienten säker vård. Sjuksköterskan ska ha kompetens att kunna fördela och koordinera uppgifter samt ha översikt av teamarbetet. Sjuksköterskan bör ha kunskap om säkerhetsarbete för att kunna garantera säker vård. Det finns ett uttryckt behov inom vården av relevanta och tidsenliga lag- och kommunikationsövningar, där teambaserade simulatorövningar framstår som en pedagogisk och tillförlitlig inlärningsmetod. Syfte: Att beskriva vad studenter vid ett lärosäte, som utbildar sig till specialistsjuksköterskor inom intensivvård, anser om teambaserad fullskalesimulatorträning. Metod: En pilotstudie där 32 sjuksköterskor som studerar till specialister inom intensivvård, ombads svara på en enkät om vad de ansåg om en simulatorövning som de genomfört där omhändertagandet av svårt skadade patienter tränades i team. Resultat: Majoriteten av studenterna ansåg att simulatorövningen haft god effekt och beskrev att övningen haft positiv inverkan på deras förmåga att öva kommunikation i ett team samt att få tillämpa teori i praktik. De uttryckte önskemål om mer simulatorträning under utbildningen samt kontinuerlig övning i sin yrkesverksamma roll. Slutsats: Teambaserade fullskalesimulatorövningar tycks vara en pedagogisk inlärningsmetod för att öka kompetenser och lära studenter att arbeta tillsammans mot ett gemensamt mål.
Aim:To describe what nursing students, specializing in intensive care, at a university college think about team based simulation training. Background: Communication and organization in health care are important factors to ensure patient safety. Nurses are called upon to be able to distribute and coordinate work tasks, while at the same time nurses should also be aware of safety promotion in health care to be able to provide safe patient care. There is a need in healthcare for team and communication training where team based simulation appears to be a pedagogic and reliable educational tool. Method: A pilot study where 32 nurses specializing in intensive care, were asked to respond to a survey on what they thought about a previously performed team based full scale simulation training. Results: In general the students confirmed that the exercise had a positive impact on their ability to practice team communication skills and to apply theory in practice. They expressed a wish for more simulation training during their education and in their upcoming professional role. Conclusion: Team based full scale simulation exercises seem to be a pedagogical teaching method to enhance competences and teach students to work together toward a common goal.

Low pressure gas carburising (LPGC) or vacuum carburising is a heat treatment process used in the aerospace and automotive industries to surface harden low alloy steel parts with carbon in the range of 0.1 to 0.25%. This project examined the LPGC process used to case harden precision gears and shafts used in various helicopter engines. Due to the stringent quality requirements specified by the OEMs (Original Engine Manufacturers) and by aerospace quality standards, approval can only be ensured through careful control of the carburising temperature, time and atmosphere during heat treatment. Final acceptance requires that the case depth, surface hardness, core hardness and component microstructure (related to the effectiveness of the quench and temper process) be controlled to within strict tolerances. This investigation utilised an industrial vacuum carburising furnace and an acetylene atmosphere to examine the effect of carburising temperature on the properties of the carburised surface layer in parts machined from 16NCD13 carburising steel. The project aimed to determine whether the total carburising time could be decreased by increasing the carburising temperature without adversely affecting the specified case depth, hardness values or microstructure. The predictions of published carbon diffusion models (taking into account the influence of temperature, changing carbon concentration and alloying element content on the diffusion coefficient of carbon in austenite) were compared with the carbon concentration profiles measured after carburising at four different combinations of time and temperature. The results showed that increasing the carburising temperature from 900°C to 940°C, while reducing the carburising time from 104 to 64 minutes, did not have any detrimental effect on the case depth, case hardness, core hardness, component microstructure or part dimensions, while resulting in a significant reduction in the total carburising time. The mechanical properties of the test pieces were within specification and the grain size was not adversely affected by the higher heat treatment temperature. Increasing the carburising temperature to 960°C (and simultaneously reducing the carburising time to 44 minutes), however, caused a reduction in mechanical properties to below specification. Published carbon diffusivity models that consider the influence of temperature, increasing carbon concentration and the alloy content of the component were found to predict the actual carbon concentration profiles to a reasonable degree of accuracy.

The purpose of this work is to find out how present manager contracts are set up in Landstinget Västmanland (the county council of Västmanland), explore managers’ perception of these contracts and why managers have chosen leadership. The work has also reviewed the question if managers need to have a relationship or expertise to the activities they lead and which qualifications are needed in such case. The survey was conducted in two divisions in which nine interviews were held with managers at all levels. In addition to this a questionnaire including the 87 managers in the divisions were held. Based on the result of the interviews and the questionnaire the study revealed five main areas : form of employment, content of manager contracts, relationships and expertise towards the operations, clinical work and profession. By applying theories the results were interpreted and the conclusion is that there is a complexity in leadership in a county organisation with strong professions and several levels of decision making. However, clear manager contracts may be a step towards successful leadership and organizational development.

This master thesis deals with the modernization of the main landing gear of the Z 143 LSi aircraft. The main emphasis is placed on optimizing of the landing gear shape and its deformation characteristics. Along with this change, variants made of different materials are examined. The landing load is calculated analytically and the load-bearing capacity of the structure is verified using the numerical FEM method. This work brings a possible replacement of the current chassis, which is production-intensive not only in time and money, but also in terms of cooperation with external companies. The objective is to design a new landing gear and verify the feasibility for the case of future implementation.

Hela det mänskliga genomet var sekvenserat i april 2003 och sedan dess har utvecklingen av genetisk testning avancerat snabbt. Sjuksköterskor kan komma att ha en central roll gällande att informera personer kring den genetiska testningen, rådgiva personer som genomgår genetisk testning och hjälpa dem att tolka resultaten. Genom att beskriva personers känslor kring att genomföra genetisk testning kan sjuksköterskor få hjälp till en ökad förståelse. Syftet var därför att beskriva personers känslor kring att genomföra en genetisk testning för genetiskt betingade sjukdomar med en möjlig dödlig utgång. För att få en överblick av det aktuella forskningsläget genomfördes en systematisk sökordsbaserad litteraturöversikt. Totalt tolv artiklar granskades och kodades. Resultatet presenteras i fyra teman: Rädsla och lättnad, som handlar om rädsla för sjukdomen, oro och ångest men också lättnaden när resultatet var negativt; Ovisshet kring hanterandet, där känslor av frustration, chock och orättvisa framkom men även förväntningar inför resultatet; Hopp och hopplöshet, vilket syntes som hopp inför framtiden och personlig kontroll samt en känsla av att vara besegrad, maktlös och förrådd; samt Gemenskap och utanförskap inom familjen, som uppstod i relation till andra där känslan av att vilja dölja samt behov av stöd var framstående. Då hälsa är vårdandets mål diskuteras resultatet utifrån Katie Erikssons hälsokors samt i förhållande till hälsa som rörelse. Ytterligare forskning och utbildning krävs för att sjuksköterskor ska erhålla kunskap om personcentrerat vårdande genom processen av genetisk testning.
The human genome was sequenced in April 2003 and since then genetic testing has developed rapidly. Nurses may come to have a central and significant role regarding informing people about all the potential outcomes of genetic testing, advising people undergoing genetic testing and helping them interpret the results. By describing people's feelings about implementing genetic testing, nurses be helped to a better understanding and ability to perform a person-centered care. The aim was therefore to describe people's feelings about implementing a genetic testing for genetic diseases with possible fatal outcome. To get an overview of the current state of research, a systematic search-terms-based literature review was performed. A total of twelve articles were reviewed and coded, resulted in four themes: Fear and relief, which is about fear of the disease, worry and anxiety but also relief when the result was negative; Uncertainty surrounding the handling, where feelings of frustration, shock and injustice emerged but also expectations for the outcome; Hope and hopelessness, which appeared as a hope for the future and personal control but also a sense of being defeated, powerless and betrayed; and Community and exclusion within the family, which arose in relation to others where feeling of wanting to hide and needs of support were prominent. The goal of caring is health. The result of this study is therefore discussed with reference to Katie Eriksson's health cross and in relation to health as a movement. Further research and education is required for nurses to obtain knowledge about person-centered care through the process of genetic testing.

Under 1990-talet skedde stora förändringar inom vård och omsorg i kommunal verksamhet på grund av kommunallagsändringen vilket innebar omorganiseringar, nedskärningar och effektiviseringar. Detta bidrog till sämre arbetsmiljö särskilt inom vård och omsorg. Belastningsskador och stress ökade. Syftet med denna studie var att undersöka enhetschefers möjlighet att utöva närvarande ledarskap samt deras och medarbetares upplevelser av ledarskap och psykosocial arbetsmiljö och hälsa. Två äldreboenden i Umeå kommun ingick i studien i sammanlagt tre fokusgruppsintervjuer, en med enhetschefer och två med medarbetare totalt 12 deltagare. En abduktiv kvalitativ innehållsanalys genomfördes. Resultatet utmynnade i sju teman och visar att enhetscheferna upplevde att de inte har någon möjlighet att vara närvarande, att det är hög arbetsbelastning för både enhetschefer och medarbetare, att det upplevs saknas socialt stöd för enhetschefer och mellan enhetschef och medarbetare, att det brister i kommunikationen, delaktighet och rättvisa. Hälsan påstods vara bättre för enhetschefer än medarbetare men trivseln är bra i båda grupperna. Närvarande ledarskap ansågs i dagsläget svårt att utöva då det saknas både tid och stöd och det finns brister i den psykosociala arbetsmiljön som påverkar medarbetarnas hälsa negativt.
In the 1990s, major changes took place in elder care in municipal activities due to changes in the municipal law which led to reorganizations, downsizing and streamlining. This contributed to poor working environment especially in health care and musculoskeletal disorders and stress increased. The purpose of this study was to examine the unit managers’ opportunity to exercise present leadership and how the psychosocial work environment is perceived by unit managers and their employees. Moreover, how leadership is perceived by the employees and how psychosocial working environment and health is investigated. Two nursing homes in Umeå municipality were included in the study. In total, three focus group interviews were conducted, one with managers and two with employees, 12 participants in total. An abductive qualitative content analysis was performed. Seven themes were found in the material. These show that the unit managers perceive that they have no opportunity to be present, and that both managers and employees perceive a high workload, lack of social support for unit managers and between unit manager and employees, and lack of communication, participation and justice. Health was perceived to be better among unit managers than employees. However, job satisfaction was reported to be good in both groups. Present leadership is in the current situation difficult to exercise due to lack of both time and support and there are deficiencies in the psychosocial work environment affecting employee health negatively.

A habitação é um direito social e um importante fator para se medir a qualidade de vida, estando ao lado da alimentação, saúde e educação. Ressalta-se que apesar de envolver um domínio específico dentro de um conjunto de fatores que possibilita a satisfação geral do ser humano, a habitação deve ser considerada como peça determinante para o desenvolvimento e o incremento da qualidade de vida da população. Neste trabalho foi analisada a eficiência dos estados brasileiros em converter os investimentos realizados no programa habitacional Minha Casa Minha Vida, que é promovido pelo governo federal brasileiro, em melhoria de indicadores sociais e de qualidade de vida. Para tanto, foi aplicada a técnica Análise Envoltória de Dados - DEA, utilizando o Modelo Baseado em Folgas - SBM (Slacks-Based Model) com retornos variáveis de escala e análise de janela, em dados relativos às Unidades Federativas brasileiras no período entre 2009 e 2012. Como resultado foi possível verificar que as regiões Sul, Sudeste e Norte foram as mais eficientes, sendo a região Nordeste a mais ineficiente. Entre os fatores explicativos, o nível de investimentos no programa e os arranjos familiares chefiados por mulheres são negativamente relacionados com a eficiência; o PIB do estado e a taxa de urbanização, por sua vez, apresentaram relevância estatística e são positivamente relacionados com a eficiência. Não houve significância estatística entre a eficiência e a densidade populacional. Como contribuição prática, pode-se afirmar que os resultados obtidos com este estudo podem direcionar os formuladores de políticas habitacionais, de modo que os investimentos no PMCMV sejam realizados com maior eficiência. Os resultados obtidos nesta pesquisa permitiram análises importantes, e por se tratar de um assunto socialmente relevante, seu estudo poderá ser ampliado em pesquisas futuras.
Housing is a social right and an important factor to measure the quality of life, near the food, health and education. It is noteworthy that despite involving a specific area within a range of factors that enables the overall satisfaction of the human being, housing should be considered as determinant part for the development and increase population's quality of life. This work analyzed the efficiency of the Brazilian states in converting investments in the housing program Minha Casa Minha Vida (My House My Life), promoted by the Brazilian federal government in improving social indicators and quality of life. The data envelopment analysis - DEA was applied, using the Slacks-Based Model - SBM with variable returns to scale and window analysis, with data relating to the Brazilian Federal Units in the period between 2009 and 2012. As a result we found that the South, Southeast and North were the most efficient, and the Northeast the most inefficient. Among the explanatory factors, the level of program's investments and family arrangements headed by women are negatively related to efficiency; the GDP of the state and the urbanization rate, in turn, showed statistically significant and are positively related to efficiency. There was no statistical difference between efficiency and population density. As a practical contribution, it can be said that the results obtained from this study can direct formulators of housing policies so that investments in PMCMV be carried out more efficiently. The results obtained in this study allowed important analyzes, and as relevant socially theme, their study may be expanded in future research.

Annotation:

Dans un objectif permanent de réduction de consommation des turboréacteurs, les constructeurs aéronautiques souhaitent atteindre de meilleurs rendements en augmentant la vitesse de l'ensemble compresseur-turbine. Afin de limiter la vitesse de la soufflante, un étage de réduction épicycloïdal doit être inséré entre la soufflante et le compresseur. Du fait de leur bonne tenue en cas de défaillance du circuit de lubrification, les roulements sont souvent privilégiés aux paliers hydrodynamiques pour les applications aéronautiques. Cependant, dans le cas des trains épicycloïdal, les roulements sont soumis à des forces centrifuges importantes qui sont la cause de pertes de puissances significatives ainsi que de la fatigue prématurée des cages ce qui peut provoquer la destruction du roulement. Ce travail de thèse consiste en le développement d'un modèle numérique permettant de comprendre le comportement dynamique d'un roulement à rouleaux cylindriques fonctionnant en champ centrifuge. Pour cela, la méthode de dynamique multi-corps est utilisée, couplée à des modèles de contact semi-analytiques tenant compte des différents régimes de lubrification rencontrés dans le roulement. De plus, un modèle élément finis est développé pour prendre en compte la flexibilité de la bague extérieure qui peut affecter la dynamique du roulement. Les résultats sont présentés pour une application classique de train épicycloïdal en termes de force, vitesse et perte de puissance. De forts impacts entre les rouleaux et la cage sont observés et les mécanismes responsables des importantes pertes de puissances et de la fatigue de cage sont expliqués. L'influence des hypothèses principales de modélisation est présentée. Enfin, une étude de l'influence des différents paramètres sur l'amplitude des forces et sur la taille et la position de la zone de chargement du roulement est réalisée
With the constant aim of reducing the turbofan consumption, aircraft manufacturers try to reach higher efficiency by increasing the compressor-turbine speed. In order to limit the fan speed, a planetary gearbox is introduced between the fan and the compressor. Because of their good oil-off performance, roller bearings are often preferred over hydrodynamic bearings for aircraft applications. However, in the case of planetary gearboxes, the roller bearings are submitted to severe centrifugal forces which cause significant power losses and premature cage fatigue that may lead to overall bearing failure. The present work consists in the development of a numerical model for the understanding of the dynamic behaviour of a cylindrical roller bearing working in a centrifugal field. Multi-body dynamics is used, coupled with semi-analytical contact models accounting for the different lubrication regimes encountered in the bearing. In addition, a finite element model is developed to account for the outer ring flexibility that may affect the bearing dynamics. Results are presented for a typical planetary gearbox application in terms of force, speed and power losses. Severe roller/cage impacts are observed and the mechanisms that cause the high power losses and the cage fatigue are explained. The influence of the main model hypothesis is presented. Finally, a study of the influence of the different parameters on the force amplitude and the bearing loaded zone shape and position is performed

A pesquisa analisa as trajet?rias individuais de mulheres quilombolas da Boa Vista dos Negros, bairro rural do munic?pio de Parelhas - regi?o do Serid? do RN. A op??o pelo recorte de g?nero, juventude e gera??o possibilitou o acesso ao universo feminino, ? intimidade da casa, ?s quest?es relativas ao trabalho e ao entendimento das configura??es familiares. O intuito ? perceber a exist?ncia de projetos individuais a partir das viv?ncias de tr?s gera??es de mulheres negras oriundas de dois grupos familiares. Tamb?m irei observar como os projetos de vida podem ser elaborados a partir de circunst?ncias vivenciadas por estas mulheres. Utilizo como m?todo para desenvolver a pesquisa, a observa??o do cotidiano, a an?lise das hist?rias de vida, entrevistas semiestruturadas, conversas informais e participa??o em programa de extens?o PROEXT/SESU-MEC. As experi?ncias femininas de ?trabalho duro no ro?ado? ou os enfrentamentos na ocasi?o das rela??es subalternas travadas no cotidiano como dom?sticas, geram interroga??es sobre as experi?ncias vividas e as estigmatiza??es sociais produzidas. A relev?ncia do trabalho est? em desvelar o universo feminino na ocasi?o das rela??es familiares e profissionais, analisar as trajetorias individuais, avaliar os estatutos sociais das mulheres ao longo de suas vidas. O registro das experi?ncias femininas possibilita a descri??o do cotidiano quilombola, dos projetos de vida das tr?s gera??es de mulheres, bem como a an?lise das transforma??es ocorridas nesta comunidade ao longo dos s?culos XX-XXI.
This research analyses the individual trajectories of quilombola women from Boa Vista dos Negros, next to the Parelhas city ? in the region of Serid?-RN. To this study, our focus (youth and generation) is important to access the feminine universe, the intimacy of home, approaching issues related to the work and to understand family configurations. We aim to perceive the existence of individual projects based on the experiences of three black women generations from distinct family groups. In order to develop this research, the method used is routine and life history analyzes, semi-structured interviews, informal conversations and personal contact due to their participation in the PROEXT/SESU-MEC extension program. The feminine experiences of ?hard work? in the agriculture or in the ?street?, coping and struggles by the subaltern relationship in their routine as housecleaners create questions related to life experiences and social stigmatizations. The relevancy of this work is to reveal feminine universe into familiar and professional relationships, analyzing individual trajectories, evaluating the social status of women along their lives. In this sense, these narratives of feminine experiences allows the description of the quilombola routine, the life projects of these three women generations, as well as it allows to analyse the changes occurred since the end of the XX century, in particular related to the familiar arrangements.

Aktiviteter är betydelsefulla för ungdomar som vistas på institution. Forskning visar att ungdomar som har en meningsfull tillvaro med aktiviteter och en variation av sysselsättning under sin institutionsvistelse har större möjlighet att lyckas förändra ett problembeteende. En institutionsmiljö bör tillgodose ungdomarnas behov av en hemlik miljö och kontakt med pro-sociala ungdomar i övriga samhället. Syftet med denna studie är att belysa aktivteters betydelse för ungdomar som är placerade på institution, relationen mellan schemalagda och icke schemalagda aktiviteter samt vilken roll personalen har i utövandet av aktiviteter för ungdomar som vistas på institution. Studiens metodansats bygger på kvalitativa intervjuer med professionella som tjänstgör på ett HVB-hem (Vård och boende) för ungdomar. Studiens resultat har analyserats utifrån relevant forskning inom området och med utgångspunkt i Piagets utvecklingspsykologi. Resultatet bidrar med förståelse för aktivteters betydelse för ungdomar som vistas på institution, samt vikten av personal som är utbildad och insatt i verksamhetens teoretiska grunder och valda metoder. Personalen har en viktig roll på flera olika sätt i utförandet av aktiviteter på en institution.
Activities are significance for adolescents who reside at institutions. Science indicates that adolescents who have a meaningful existence with activities and a variation of occupations at the institution have greater opportunity to succeed in changing behavioral problems. An institutional environment should satisfy the adolescent’s need of a homelike environment and the need of meeting other pro-social adolescents from the society. The intention with this research is to highlight the importance of activities for the adolescents who are placed at institutions, the relation between scheduled activities and non scheduled activities as well as to see what role the staff has during the exercise of activities at the institution. This research is based on qualitative interviews with professional staff at an institutional accommodation for adolescents. The research result has been analyzed with relevant science in the specific field and from Piaget’s developmental psychology. The result contributes with an understanding for the activities significance for the adolescents who residing in institution and for the importance of that the staff are educated and has knowledge in the institutions selected theoretical methods. The staff has an important role in several ways during the exercise of activities at the institution.

This research studies how internal and external factors impact the management of working capital. We use a sample of 519 publicly-traded companies listed on the S??o Paulo Stock Exchange, considering the period from 2000 to 2015. We find evidence that the external factors, the SELIC base interest rate, and the BNDES System's credit disbursement, impact the companies' working capital level. Our finding comply with previous studies that analyze the internal factors such as, debt level and free cash flow. We find that higher levels of cash flow increase working capital levels, and that companies' debt level does not influence the working capital management.
Esta pesquisa estuda como fatores internos e externos impactam o gerenciamento do capital de giro. Trabalha com uma amostra de 519 companhias de capital aberto listadas na Bolsa de Valores de S??o Paulo, considerando o per??odo de 2000 a 2015. Encontra evid??ncias de que os fatores externos, taxa b??sica de juros SELIC, e desembolso de cr??dito do Sistema BNDES, interferem no n??vel de capital de giro das companhias. Segue estudos anteriores que analisaram os fatores internos, endividamento e fluxo de caixa livre, constatando que n??veis maiores de fluxo de caixa aumentam os n??veis de capital de giro, e que o endividamento das companhias n??o influencia o gerenciamento do capital de giro.

No contexto das doen?as cr?nicas n?o transmiss?veis, que imperam no novo cen?rio epidemiol?gico, faz-se necess?ria a reformula??o do modelo de assist?ncia e a inclus?o de novas tecnologias com o objetivo de formar redes de aten??o ? sa?de capazes de responder de forma satisfat?ria a essa demanda emergente. Diante desse cen?rio, a Gest?o da Cl?nica traz ferramentas importantes, dentre elas as Linhas-Guia (LG) cujas recomenda??es orientam a pr?tica dos profissionais no manejo de condi??es cr?nicas priorit?rias no Sistema ?nico de Sa?de. Contudo, por motivos de ordem pol?tica e organizacional, a implanta??o dessas ferramentas acontece de forma incipiente, sem a efetividade e perenidade esperadas. O objetivo do estudo foi verificar, nos munic?pios da regi?o de sa?de de Itabira, a interfer?ncia na implanta??o das LG dos seguintes processos de trabalho da Aten??o Prim?ria ? Sa?de: territorializa??o, cadastro populacional, diagn?stico situacional, protocolos municipais, agenda, educa??o permanente, plano de cuidado, conselhos locais de sa?de, acesso e coordena??o da Aten??o Prim?ria. Para isso, a partir de um estudo quantitativo transversal, foi utilizada a metodologia multi-attribute utility theory (MAUT). Os resultados apontam para os processos de trabalho agenda, diagn?stico e acesso, os quais apresentaram uma correla??o de moderada a boa, estatisticamente significativa. Verificou-se a frequ?ncia de implanta??o das LG de forma individualizada, evidenciando um n?mero maior de munic?pios utilizando as LG da gestante, hipertens?o e diabetes. Observou-se ainda que, apesar de estarem sob uma mesma jurisdi??o, existem iniquidades na operacionaliza??o dos processos de trabalho entre os munic?pios. Por fim, foi encontrada uma rela??o direta, moderada (0,55) no que tange aos processos de trabalho da Aten??o Prim?ria e implanta??o das LG. Discute-se que os processos de trabalho citados como tendo melhor correla??o configuram estrat?gias fundamentais para fortalecimento de v?nculos e garantia do continuum do cuidado. As LG usadas mais frequentemente auxiliam os profissionais no manejo das condi??es de sa?de mais comuns e, por consequ?ncia, apresentam maior aplicabilidade na rotina assistencial. Buscou-se entender as iniquidades entre os munic?pios a partir das intera??es socioculturais locais. Os achados, de forma geral, contribuem para com a gest?o no ?mbito da Avalia??o em Sa?de municipal, regional e estadual, evidenciando condicionantes para uma efetiva implanta??o das LG. Al?m disso, fortalece a metodologia MAUT como ferramenta avaliativa na ?rea da sa?de.

In the context of chronic non-communicable diseases, in which prevails over the new epidemiological scenario, it is required to reformulate the assistance model and the inclusion of new technologies aiming healthcare networks capable of responding satisfactorily to this emerging demand. Given this scenario, the clinical management introduces important tools, among them, Linhas-Guia (LG/Guidelines), whose recommendations guide the practice of professionals in the management of priority chronicle conditions at SUS (Brazilian Health Service). However, political and organizational bureaucracy results in a lack of effectiveness and expected longevity of the implantation of these tools in an incipient way. The goal of this study was to verify the interference in the implementation of the Guidelines for the following Primary Health Care work processes in the municipalities under the jurisdiction of the Regional Health Management of Itabira: territorialization, population registry, situational diagnosis, municipal protocols, agenda , permanent education, care plan, local health councils, access and coordination of Primary Care. In this regard, it was used a multi-attribute utility theory (MAUT). The results indicate that the work processes agenda, diagnosis, and access presented a correlation of moderate to good, statistically significant. The frequency of LG implantation was verified in an individualized way, emphasizing a larger number of municipalities using pregnant women, hypertension, and diabetes? LG. It was also detected inequities in the operationalization of work processes between municipalities, even though belonging to the same jurisdiction. Finally, a direct connection, moderate relationship (0.55) was found regarding Primary Care working processes and LG implantation. It argues the work processes cited as having the best correlation constitute fundamental strategies to reinforce the bonds and guarantee the continuum of care. The most frequently used LGs help professionals in the management of the most common health conditions and, consequently, have a greater applicability in the care routine. The aim was to understand the inequities between municipalities based on local socio-cultural interactions. The findings widely contribute to the management, within the scope of Health Assessment, at municipal, regional and state level, highlighting the conditions for an effective implementation of LG. Moreover, it strengthens the MAUT methodology as an evaluation tool in the health area.

The garage door is an industrial product that can be seen everywhere. The main method of lifting the electric roller door is controlled by the motor and the rear-stage magnetic brake mechanism. At present, most of the large-scale AC roller door motor products have the problem of the brake system and the operation of the rear manual mechanism is inconvenient. There are many safety concerns, so the brake mode and mechanism actuation mode of the rolling door motor is particularly important. The CAE computer-aided engineering analysis method and design are used to optimize and improve the rolling door motor brake and manual operation mechanism, and the simulation design results are evaluated to achieve the goal of increasing durability and reducing production cost. This paper uses Autodesk Inventor design and computer aided engineering software (Inventor Stress Analysis) as the main tool, and uses 3D list machine (3D printer) and numerical control machining center (CNC machining center) to make proofs for real machine test, using digital I / O The interface card (National Instruments PCI6601) performs design verification in sequential control mode, digital I/O for data acquisition and analysis, and performs the Taguchi’s orthogonal experiments of the brake system to find the optimal control parameter combination for the stopping angle and time of the brake. This study can effectively reduce the damage caused by improper operation of the iron roller door, greatly improve the safety of the operator, and improve the process and material cost problems at the design source, greatly reducing the delivery time and manufacturing cost.

ABSTRACT The innovative financial products in Taiwan has been gradually developed under the rapid-changing global financial environment. The three gear ETFs which are listing in August 2009 in the Taiwan Stock Exchange are new and needed to be explored., This paper studies the structure, risk and performance of the three gear ETFs. This paper uses descriptive research method to describe the structure and risk of the three gear ETFs and uses descriptive statistics to evaluate performance. Daily samples are collected from August 2009 to March 2010. “Hang China”has 158 data,“Hang Hong Kong”has 158 data, and“Polaris CSI 300”has 152 data. This paper finds that in addition to the general risk happened in funds, there are some specific risk happened as cross-border listing. This paper also findes that errors occurred in exchange rate fluctuations(especially as the appreciation of NT dollar against Hong Kong dollar), the discount/premium between the market value and equity value, and tracking the underlying index. This study finds that:(A)The performance of three gear ETFs do not win the underlying fund, the gaps are expanded because of the appreciation of NT dollar against Hong Kong dollar,but really close to the underlying index performance.(B)On average, the performance of equity are slightly lower than market value, but the deviations are not different significantly.(C)The deviations of net worth and market price are escaped over time, continuing about two to three days because of arbitrage mechanism.

Background: The increasing presence of globalization in our everyday life makes it apparent that internationalization is no longer a topic relevant only for a few multinational companies, but for essentially every company that wishes to expand or even survive in their domestic market as well as in foreign markets. In light of this, research on how firm chooses FMEM has surged, and it is evident that it is an important topic. Numerous theories and factors have been examined in order to explain what motivates the choice of FMEM, but there is notable absence in connecting the business model to the FMEM. Despite the increasing attention and prominence of the business model, to date, there is little research that looks at FMEM decisions through a business model perspective. Purpose: The purpose of this study is to answer the calls for new aspects and theories on the FMEM research field by exploring the role that the business model has on the choice of FMEM. This study will be executed through mapping a company’s business model and FMEM choice by collecting qualitative data through interviews to find links between the business model and the entry mode. Method: This research is conducted through a qualitative single case study, using in-depth interviews for primary data collection. Conclusion: The results of the analysis that was based on the empirical findings derived from the data collection, led to several conclusions being drawn. Firstly, the business model of the case company has had a great impact on the choice of FMEM of that company. Secondly, apart from influencing the choice of FMEM, the company’s business model has also contributed to the company further committing to their existing FMEM. Thirdly, as long as the case company intends to operate the same business model, with the same value drivers, it is likely to continue its commitment towards its existing FMEM.

These are the results: (1) The automobile parts in performance of financial and sales is growing positively after G company introduced ISO/TS 16949 quality system. The total sales amount ratio of automobile parts raised from 0% in 2009 to 28.5% in 2015. (2) The performance analysis of internal organization is improving after company G introduced ISO/TS 16949 and AS 9100 quality system. (3) The performance analysis of external organization in general parts of customer satisfaction is improving in positive way after company G introduced ISO/TS 16949 and AS 9100 quality system. Overview the whole performance of company G in recent years, although the general industry gear parts are decreasing, in high precision requirement of automobile transmission gear, hybrid car gear box and battery electric vehicle gear box are all raising rapidly. These evidence shows the benefits of the company G’s right decision in introducing ISO/TS 16949 quality system. On the other hand, the introducing of AS 9100 takes longer period of time to improve on performance, and result in strategic decision for now. Therefore, the specific improving results are still not available for the company to introduce AS 9100.

Small and medium-sized enterprises are up to 95% of machinery industry in Taiwan, it shows that they developed professional job assignment and formed industrial clusters. But facing intense economic competition, manufacturers must improve production flexibility and respond quickly to the market for satisfying customers' needs. In that case outsourcing is one of manufacturers' common way to improve production efficiency. Therefore, this paper will construct the outsourcing vendor selection matrix by a case study of grinding process of gear, because the gear is one of very important and widely applied parts for the machinery, its functions are to transmit power, change power direction, rotate speed and so on, and the grinding process is one of major processing procedures for producing gears. First, this paper will define the six sigma quality level index and manufacturing time index. Then, create a time-qualified rate as the horizontal axis, six sigma quality index as the vertical axis to construct outsourcing selection matrix, and establish outsourcing manufacturer selection rules to provide industry for selection. Avoiding the probability of misjudgment caused by the performance of the samples, we will estimate the upper confidence limit according to the samples and infer rigorously. The results will be drawn in the outsourcing vendor selection matrix chart to determine the five outsourcing manufacturers’ performance. They whose manufacturing time and process quality meet requirements will be selected, as well as ones with poor performance will be suggested for improving. This paper constructs the outsourcing vendor selection system can help the industry to observe the outsourcing manufacturers' performance more conveniently, grasp their process more fully, manage more easily, and realize the poor performance ones' weaknesses from the figure for enhancing the manufacturing quality and manufacturing time performance.

The life-cycle cost analysis is accomplished for both the linear replacement units (LRU) and shop replaceable units (SRU) to identify the optimal level of repair through the evaluation of system cost effectiveness and operational availability requirements. The results of this evaluation are then compared with the existing maintenance policy to derive the recommendations for corrective action and/or design improvement. Based on the technical documents of the landing gear system, this research utilizes the Equipment Designer’s Cost Analysis System (EDCAS® v3.0) and the Air Forces Logistics Information Management System (LIMS) to establish and construct the hardware structures of the landing gear system, as well as to collect the related logistics data. After analyzing and comparing with the current situation, we derive the suggestion for the optimal repair level in which there are 31 SRUs being different from the existing maintenance policy. Through analyzing hardware characteristics, we arrange the 31 SRUs into five categories. In each category we choose one item to further analyze and compare.

The study of human error in maintenance of the impact of Air Force aircraft, and landing gear systems, flight operations department and maintenance of the engine system operators is analyzed, the questionnaire structure is the core concept SHELL mode, the reason for classification of human error induced for the LS (people to software), LH (people to hardware), LE (people to the environment), L (of their own limitations), LL (people to people) in five dimensions and the layer is divided into 17 criteria, the use of multi-criteria decision analysis theory of AHP, CRITIC method, the standard deviation method and Grey method were seeking their weights, the weight of AHP by subjective analysis and found that the major factor inducing human error is the whole L (of their own restrictions) in the first place, which replaced the "staff of the psychological state of" maximum value for the weights, showing that psychological adjustment to staff the root causes of human errors induced. Supplemented by the objective weight CRITIC method, the standard deviation method and the weight of ash analysis of the implementation of related laws, there is a significant causal relationship exists, the gray relational method is obtained by "lack of equipment or hand tools," the first sort, showing that a lack of equipment, a great impact, maintenance staff to achieve the task, as must use non-standard hand tools to perform the repair, which will indirectly causing psychological stress, inconsistent with hand tools to perform the repair, construction quality be compromised, resulting in more effective, even derivative accident unfortunate.

Playroom equipment can be very good learning tools for children. Digital interaction devices are an excellent means of connecting users to information especially in the case of children who absorb information readily. This paper reports our work with spiral lift models and gears as a starting point for understanding the relationship between children and the technology associated with these devices. This research project was carried out in close cooperation with Kidsburgh the famous indoor playroom company in Taiwan. The project uses the ball pool area of the playroom to achieve the purpose of both entertaining and allowing children to play using interactive equipment. This interactive concept model has a transparent housing. Rotating a handle turns a pair of bevel gears that turn a cylinder, this causes a ball to roll around a spiral wall. Operation of the device allows children to feel a sense of accomplishment, in a safe operating process, and a Phidget RFID device on a ball triggers the generation of images and music. The attributes of this creation can be summed up as follows: (1) The design of the transparent housing cover allows the children to see inside the body and observe the gears moving. This gives them an insight into the basic concepts of powered machinery. (2) Rotating the handle to allow the ball to roll along the outer spiral wall adds a visual appreciation of a three-dimensional structure. They understand that this is a mechanism by which means the ball can be transported back and forth in a practical way. (3) When the RFID tag on the ball is detected by the Phidget RFID device, the monitor plays an animation and generates images and music. This promotes the growth and appreciation of musical notes and color vision in the child. This interactive concept model was displayed in the “2013 Maker Fair: Taipei” exhibition, and the effectiveness of the design was explored by means of surveys. Interaction is expected to be more closely integrated with future playground equipment to promote creativity and provide more fun.

This thesis explores the tensions between nation building and globalisation in relation to state-sponsored visual arts projects, focusing on the Biennale project of the Greater Johannesburg Metropolitan Council (GJMC). It explores the extent to which this project - aimed initially at internationalising and then globalising South Africa’s art world following the demise of apartheid in 1994 - was compatible with key nation building objectives for state funding of the arts, captured imperfectly in the country’s Reconstruction and Development Programme (RDP). It is found that the Biennale project was largely not compatible with the RDP’s objectives for state funding, namely to promote national unity while respecting the country’s cultural diversity, redress imbalances of the past in access to the arts, and promote culture as a component of South Africa’s development, in spite of the GJMC’s statements to the contrary. Rather the Johannesburg Biennale reproduced the dialectic of economic inclusion and exclusion endemic to the political project of globalisation, leading to the creation of economic and artistic ‘insiders’ and ‘outsiders’ akin to the ‘First World’ and ‘Third World’ divide that the RDP warned against in its principle on nation-building, and proved to be an inappropriate use of state resources given the divided nature of the South African artworld. Furthermore, the GJMC imported uncritically an exhibition form associated with the discourse of internationalisation in the first Biennale, and then globalisation in the second, from other Biennales, based on contestable theoretical positions on nationalism and globalisation. This they did in an attempt to address a growing financial crisis in the city by using a ‘one size fit all’ set of policy prescriptions falling under the rubric of neo-liberalism, including culture-led methods of enhancing a city’s global status to attract foreign revenue. In particular, the Biennale did not learn the lesson that the shift in focus in other Biennales from internationalisation to globalisation, was also accompanied by growing discontent in these countries about the elitist nature of these events. I also consider whether it is possible to devise an alternative Biennale project that uses international contact to unite the South African artworld, rather than dividing it.
