The walker is regarded as a promising solution to provide additional support to maintain balance or stability while walking for elderly people. Significant assistance in improving mobility technology have been observed from literature review. However, the walkers available in the market is possible to optimize in design and include additional functionality, including getting out of the seat at home with caregiver aid, emergency care aided system. Considering falling down is a public healthcare problem, we designed the emergency aided system to rescue them [1].   In this paper, we proposed a multiple function elderly mobility and emergency aid system, was developed and modelled by Inventor 2015, and finite element analysis. Simulation was then created to get the value of safety factor, and make comparison base on the results from structural calculation. Finally, the application of few features of the improved walker was illustrated.

In 1968, Dr. Margaret Walker Alexander, professor of English at Jackson State College, founded a Black Studies Institute in Jackson, Mississippi. This study is an intellectual, institutional and social movement history that utilizes archival research and textual analysis of Alexander’s writings, poetry, and work as teacher and director of the Institute in the context of the Black Campus Movement (BCM) and Black Freedom Struggle. It pushes the boundaries of historiographical scholarship on BCM that overshadows the epistemological and aesthetic politics of women faculty-activists who ushered forth racialized and gendered analysis as well as developed the foundations of Black Studies.

The challenges of producing and directing small professional theatre in any metropolitan area are many. This thesis is concerned with the process of finding a producing theatre, casting, rehearsal and staging the play, "Nothing Sacred" by George F. Walker, in the Washington D.C. metropolitan area. Unlike many thesis projects this one was conducted completely outside of the university setting and is thus a true reflection of the small professional theatre community.

Though bound historically through hundreds of years, the African-Native American relation has not received much attention by scholars of literature; hence, the emphasis of this thesis is to investigate the literary portrayal of the interethnic relation between African Americans and Native Americans through the blues trope. The blues trope provides an intriguing literary platform for the psychological and physical struggles in finding an identity within such a diverse multiethnic society like the United States. For African American writer Alice Walker and Native American author Sherman Alexie the blues trope is a successful literary device in expressing long lost and rediscovered emotions, identities and hopes among an ever growing multiethnic nation.

A Research Report submitted in partial fulfilment of the requirements for the degree of Master of Arts in English Education at the University of the Witwatersrand Johannesburg, November 1998 / With the emergence of South Africa as a new democracy and the concomitant new constitution there has been interesting and subtle change in the context in which I teach. The composition of my classrooms has changed and thus I have used journal writing by the students to try to deal meaningfully and transformatively with these changes. My classroom had within a relatively short space of time, become a multi-cultural one in which silences, different from those I had previously noticed, emerged. [No abstract provided.

Caminhar na cidade Experiência e representação nos caminhares de Richard Long e Francis Alÿs; Depoimentos de uma pesquisa poética é constituído de reflexões e depoimentos sobre a poética do caminhar na cidade hoje. Parte-se de um entendimento do caminhar como uma prática artística, tal como se desenvolveu no decorrer do século XX no campo das artes visuais. Procura-se compreender as práticas de artistas-caminhantes contemporâneos, suas formas de inscrição e intervenção no espaço urbano, com foco nas dimensões da experiência e da representação. Apresentam-se: 1) o campo poético do artista inglês Richard Long, artista-caminhante em paisagens naturais remotas, abordando especialmente a relação entre a obra e o lugar; 2) o campo poético do artista belga Francis Alÿs, artista-caminhante urbano, com um aprofundamento sobre a especificidade da inscrição artística no contexto urbano e o processo de criação das situações metafóricas e proliferação das fábulas no imaginário urbano. 3) depoimentos da pesquisa poética da própria autora, suas experiências na cidade como artista-caminhante. A partir destas três práticas artísticas, concluem¬-se quais os procedimentos utilizados por artistas-caminhantes. / Walking in the City Experience and representation on Richard Long and Francis Alÿs walking-works; a poetic research testimony consists on reflections and testimonies on city walking poetics today. Arising from an understanding of walking as an artistic practice, as it was developed in the course of the 20th century in the field of visual arts. There is a search for an understanding of contemporary artists-walkers practices, their forms of inscription and intervention on the urban spaces, deepening the experience and representation aspects. Presenting: 1) the poetic field of the English artist Richard Long, walker in remote natural landscapes, tackling the relation between work and place; 2) the poetic field of the Belgian artist Francis Alÿs, urban walker, with a focus on the artistic inscription on the urban space specificity, and the creative process of metaphoric situation and the proliferation of fables in the urban imaginary; 3) the authors own poetic research testimonies, her city experiences as an artist-walker. Based on these three artistic practices, the artistic procedures taken by the contemporary artists walkers shall be concluded.

En stillasittande livsstil utgör idag ett mycket stort folkhälsoproblem och fysisk aktivitet är något som förespråkas i samhället. Motivation är en förutsättning för att en person skall kunna förändra sin livsstil. Distriktssköterskan skall befrämja den fysiska, psykiska och sociala hälsan och kan göra det genom att hjälpa människor att finna sin egen motivation. Distriktssköterskan möter patienter med skilda hälsoproblem och olika grad av motivation. För att kunna möta människors olika behov är det av betydelse att ha kunskap och förståelse för vad motivation innebär och hur det uttrycks. Syftet med denna studie är att beskriva och belysa begreppet motivation ur ett generellt perspektiv och utifrån ett specifikt kontext, patienters motivation i samband med fysisk aktivitet. En begreppsanalys har gjorts utifrån Walker och Avants analysmodell (2005). De egenskaper som karaktäriserar begreppet motivation har definierats, ett modellfall, ett gränsfall och ett motsatt fall har beskrivits för att ge en tydligare bild av motivationens karaktäristiska egenskaper. Förutsättningar och konsekvenser för begreppets existens har lyfts fram och därefter beskrivs empiriska referenser för ytterligare beskriva och tydliggöra begreppet. Den slutliga beskrivningen av begreppet motivation resulterade i ett mångfasetterat svar. I ett specifikt kontext med patienters motivation i samband med fysisk aktivitet beskrivs oftast motivation utifrån vad som är motiverande. De vanligaste motiverande faktorerna är; En tro på de positiva hälsokonsekvenserna, skapa självkontroll/självförtroende och social kontakt. Det framkom att självkontroll, social kontakt, att ha ett mål och övertygelse var förutsättningar för motivation i samband med fysisk aktivitet i det analyserade materialet. Distriktssköterskan bör vara medveten om värdet av motivation och framför allt att människor drivs av olika motiv och därmed motiveras av olika faktorer. Enligt analysmodellen kan de definierade egenskaperna för begreppet inte vara det samma som förutsättningarna för begreppet. Utifrån analysen framkom det ändå att vissa av de definierande egenskaperna var förutsättningar, vilket presenteras trots att det strider mot modellen. / <p>Program: Specialistsjuksköterskeutbildning med inriktning mot distriktssköterska</p><p>Uppsatsnivå: D</p>

The work described in this thesis is inspired by natural-occurring molecules that are used throughout biology to perform specific, highly-selective tasks. This thesis illustrates the design, synthesis and investigation of novel molecular devices based on acyl hydrazones for the synthesis of a small molecule walker and light-driven molecular shuttles. Chapter One outlines a general overview of the design and synthesis of molecular devices, including molecular walkers and molecular shuttles. Some of the most important examples of walking molecules (both natural and synthetic) are described in detail, along with a comprehensive introduction of molecular shuttles and their synthetic mimics. Examples of stimuli-responsive molecular shuttles that have been developed are highlighted throughout the chapter. Chapter Two describes the design and synthetic progress towards a molecular walker, as well as detailing the optimisation of the synthetic steps achieved thus far. In this chapter, most of the work presented is based on the design and optimisation of the synthesis of an acyl hydrazone-based molecular walker, which will be able to walk directionally and repetitively along its conjugate track when the conditions are changed. A novel acyl hydrazone pyridine moiety is introduced to the system to achieve a high directional bias during the walking process. First, the concept and basis of the design is explained and further, the synthesis of the walker system is discussed in detail. Chapter Three illustrates the synthesis and operation of 1- and 2- station [2]-rotaxanes which exhibit all the requirements for a light-driven molecular shuttle. The effect of a new photo switchable binding station, an acyl pyridyl hydrazone, on the shuttling process is investigated by comparing the positional distribution of the macrocycle between the acyl hydrazone station and the succinamide-ester station, while the acyl hydrazone undergoes photo- and thermal isomerisation. The successful synthesis of this molecular architecture is described along with its operation, demonstrating high positional integrity and efficiency during the shuttling process.

Small molecule walkers developed to date take advantage of the reversibility of dynamic covalent bond formation to transport molecular fragments along molecular tracks using both diffusion processes and ratchet mechanisms. However, external intervention (the addition of chemical reagents and/or irradiation with light) is required to mediate each step taken by the walker unit in systems reported so far. In this Thesis, the first synthetic small molecule able to walk back-and-forth upon an oligoethylenimine track without external intervention via intramolecular Michael and retro- Michael reactions is described. The 1D random walk is highly processive and exchange takes place between adjacent amine groups in a stepwise fashion. The walker is used to perform a simple task: quenching of the fluorescence of an anthracene group situated at one end of the track as a result of the walking progress. In the presence of excess of base, the molecule preferentially ‘walks’ towards the favoured final foothold of tracks of increasing length and it is possible to monitor the population of all or a few positional isomers over time. In each case the molar fraction of walkers reaching the final foothold is determined quantitatively by 1H NMR. Control over the rate of exchange is achieved by varying the amount of base added. The dynamic migration of a small molecule upon the track is a diffusion process limited to one dimension and as such can in principle be described using the one dimensional random walk. Chapter I identifies a set of fundamental walker characteristics and includes an overview of the DNA-based and small molecule transporting systems published to date. Chapter II describes the inspiration for this work and model studies which lay the groundwork for the research presented in this thesis. The initial track architecture and optimisation of reaction conditions are demonstrated using a simple model compound which then led to the development and a detailed investigation of a first synthetic small molecule able to walk upon an oligoethylenimine track without external intervention. Chapter III presents a modified synthetic route towards the desired walker-track architectures and a comprehensive investigation of the dynamic properties of a series of tracks of increasing length upon which the walker migrates in a unidirectional fashion. The Outlook contains closing remarks about the scope and significance of the presented work as well as ideas for the design of novel small-molecule walkers, some of which are well under way in the laboratory. Chapter II (with the exception of model studies included at the beginning of the chapter) is presented in the form of article that has recently been published. No attempt has been made to re-write this work out of context other than merging content of the article with the supplementary information published together with the article. Chapter II is reproduced in the Appendix in its published format.

FundaÃÃo Cearense de Apoio ao Desenvolvimento Cientifico e TecnolÃgico / A presente dissertaÃÃo, inserida dentro dos estudos aplicados aos processos criativos do Tea-tro de Rua ContemporÃneo, lanÃa-se ao desafio de refletir sobre o processo de montagem e circulaÃÃo de âO Jardim das Flores de PlÃstico / ato 3: Por baixo do saco pretoâ, espetÃculo teatral montado pelo Grupo NÃis de Teatro, em Fortaleza, no primeiro semestre de 2015. A partir da experiÃncia das caminhadas do grupo teatral na periferia urbana, seja no processo de montagem ou na prÃpria lÃgica de encenaÃÃo/dramaturgia proposta ao espectador, o estudo se pergunta sobre as possibilidades desse teatro feito na periferia da cidade na construÃÃo de situaÃÃes poÃticas que inflamem dissensos nas operaÃÃes estratÃgicas de normatizaÃÃo das vidas e segregaÃÃo dos espaÃos da urbe. Reconhecendo um teatro que se faz imanente no es-paÃo urbano, o que o caminhar como prÃtica de espaÃo em fluxo oferece de potÃncia reflexiva e criativa para o trabalho do artista que se lanÃa a este desafio? A proposiÃÃo do trabalho Ã, expandindo o campo de aÃÃo das Artes CÃnicas, estimular o diÃlogo entre teatro e urbanismo, refletindo sobre o que o caminhar pelas periferias urbanas reconfigura, a partir do sensÃvel, sobre a prÃpria experiÃncia de cidade.
