    Distance measurements in inhomogeneous cosmologies2007Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    When making a raytracing program for supernova Ia data for calculations of an inhomogeneous and anisotropic universe with a zero curvature over all, it may be found that the possible negative pressure, the so-called dark energy, that is the presumable cause for an assumed accelerating expansion of the universe, is an optical illusion. The observably faint distant supernovas could thus be a result of gravitationally distorted light rays curving through the inhomogeneous universe, lengthening the travel distance to the observer. The local curvature is taken into account when the light ray travels through space, bending its path according to gravitational lensing. Comparing the magnitude from the simulated light ray, from a 0.5x0.5 degree portion of the sky, with the best-fit-curve of real SN Ia data, we however only see a very small difference. Hence is the effect due to inhomogeneities not as significant as believed. Our results were plotted as magnitude as a function of redshift and compared with observational data from a group of scientists searching for high redshift supernova type Ia, called the supernova cosmology project. The search for answers to how the universe is behaving, and more importantly: ''why?'', are still not concluded. Just because our results do not show the anticipated values for a non-accelerating expansion of the universe, there are still many effects to investigate. The over- and under-densities influences the way we measure the light distances to us and can still be imitating the visual effects of an accelerating universe. Also, the inhomogeneity should effect the very expansion dynamics itself, which is a topic for future studies.

    Det korta mötet med barn i vården: En litteraturstudie om upplevelser hos sjuksköterskor2018Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Inledning: Den största anledningen till att barn kommer i kontakt med sjukvården är på grund av misstänkt fraktur, vilket innebär att röntgensjuksköterskor ofta möter barn i det dagliga arbetet på röntgenavdelningen. Trots det är dessa sällan utbildade i bemötande av barn, eller inom pediatrisk bildtagning. Vuxna som inte är vana vid att hantera barn kan känna viss tveksamhet eller rädsla inför att vårda ett barn. För att kunna förbättra mötet med barn är det viktigt att veta vilka känslor sjukvårdpersonal känner i mötet, och varför. Syfte: att beskriva vilka upplevelser sjukvårdpersonal känner i mötet med barn. Metod: Studien utfördes som en litteraturöversikt med 10 artiklar som granskades med en induktiv kvalitativ innehållsanalys. De 10 artiklarna var av kvalitativ ansats och intervjuade sjukvårdspersonal som bestod av ambulanspersonal, akutsjuksköterskor, allmänsjuksköterskor och radioterapeuter. Resultat: Fyra kategorier; bemötande, hanterbarhet, tiden har betydelse och föräldrar. Dessa beskriver i vilka situationer sjukvårdspersonal upplever både negativa och positiva känslor i mötet med barn. Slutsats: att identifiera vilka känslor som uppstår är grunden för fortsatta studier för att förbättra arbetsmiljön för såväl röntgensjuksköterskor som övrig sjukvårdspersonal.

    Arbetsterapeuters erfarenheter av att identifiera samt främja meningsfulla aktiviteter hos personer som är 80 år och äldre.2018Independent thesis Advanced level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Purpose: To describe occupational therapists' experiences of identifying and promoting meaningful activities with people aged 80 years and over, with homecare. Method: The authors chose a qualitative approach to describe the subjective experiences of the occupational therapists. Eight semi- structured interviews were conducted and analyzed on the basis of qualitative content analysis. Result: The data resulted in three categories, one with two subcategories these were: Identification of individual needs for meaningful activities, Work promoting against meaningful activities with subcategories: Problems occupational therapists meet with the elderly as well as supportive resources to maintain meaningful activities,as well as the category of Occupational Therapists' lack of and the wish for resources to work towards meaningful activities. Conclusion: The study shows that occupational therapists in the field of home care focus on starting from the patient's individual life story and they see a danger with generalizing when working with patients aged 80 years and over. Occupational therapists' experiences also showed that minor efforts and the social network of relatives and friends are important for the patients to be able to carry out meaningful activities. The participants in the study showed a great commitment to their work while expressing a wish to do more for the patients.

    Packaging development: A key factor to increase customer satisfaction and firm competitiveness2012Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    The purpose of this study is to develop the packaging function at a manufacturing company in order to increase customer satisfaction and thereby increase the firm’s competitiveness. This is an exploratory case study conducted at Scania Engines, a large manufacturer of industrial-, marine- and power generation engines. The empirical findings in this study are gathered through questionnaires and interviews with customers and distributors of Scania as well as with key personnel within the organization.The result of this study shows that Scania need to get out of the traditional view of packaging as solely a means of protecting the product during transport. It is important to see packaging as a function that can add value to the customer instead of viewing it only as a cost center. Furthermore, it showed that the customer’s demands regarding packaging mainly have to do with information and communication, promotion of the package, apportionment and environmentally designed delivery pallets.

    Avtalsslutande genom internet: En genomgång av avtalsrätt i förhållande till internet samt online auktioner2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Tekniken utvecklas mer för varje dag och i takt med detta så ingås avtal allt mer i elektronisk form. I takt med teknologisk framgång uppstår det dock nya problem. Frågan är om den åldrande regleringen i avtalslagen för traditionella avtal kan appliceras på dessa nya problem i förhållande till elektroniska avtal. Syftet med arbetet har varit att fastställa gällande rätt för elektroniska avtal. För att kunna göra detta har en redogörelse av innehållet i traditionell avtalsrätt gjorts. Därefter följer en analys samt en jämförelse av likheter och skillnader gentemot varandra. Detta arbete har använt traditionell juridisk metod för att besvara syftet. Resultatet av arbetet är att avtalslagens allmänna karaktär gör att lagen är applicerbar på elektroniska avtal samt internetauktioner. Det finns dock viktiga skillnader som med hjälp av praxis kommer klargöras. Den teknologiska utvecklingen i form av till exempel elektroniska signaturer har sett till att det nu är säkrare än någonsin att ingå elektroniska avtal.

    Hur utvecklar man ett matfestivalkoncept ur ett upplevelseproduktionsperspektiv?: exemplifierat med en konceptutveckling för Vaxholms matfestival2012Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The purpose of this essay was to examine how existing food festivals work with concept development, thematisation and storytelling from an experience production perspective. Interviews were conducted with three strategically chosen food festivals in Scandinavia; Den Norske Matfestivalen i Ålesund, Matfesten i Skellefteå and Matfestivalen i Skövde. The essay describes theories of experience production as; concept development, thematisation and storytelling. Vaxholm Food Festival wish to create a food festival, in early June, with a intention to extend and act as a starting point for the summer season in Vaxholm. Based on interview results and literature search, I have developed a concept of these approaches for an upcoming food festival - Vaxholm Food Festival. By using thematisation and storytelling while developing a concept, you can create a feeling that pervades the festival and distributed to the guests. In addition, it can have a positive impact on the destination's image and attractiveness and to attract more guests. My results show that none of the investigated food festivals today use either concept development, thematisation or storytelling. The concept has been developed describing Vaxholm Food Festival aims, objectives, target audience, organization and marketing. It also contains proposals on various themes and a concrete proposal on the theme ”The origin of the food”, which contains ideas for activities, entertainment and storytelling.

    Haptic Navigation Aids for the Visually Impaired2016Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    Assistive technologies have improved the situation in society for visually impaired individuals.The rapid development the last decades have made both work and education much more accessible. Despite this, moving about independently is still a major challenge, one that at worst can lead to isolation and a decreased quality of life. To aid in the above task, devices exist to help avoid obstacles (notably the white cane), and navigation aids such as accessible GPS devices. The white cane is the quintessential aid and is much appreciated, but solutions trying to convey distance and direction to obstacles further away have not made a big impact among the visually impaired. Onefundamental challenge is how to present such information non-visually. Sounds and synthetic speech are typically utilised, but feedback through the sense of touch (haptics) is also used, often in the form of vibrations. Haptic feedback is appealing because it does not block or distort sounds from the environment that are important for non-visual navigation. Additionally, touch is a natural channel for information about surrounding objects, something the white cane so successfully utilises. This doctoral thesis explores the question above by presenting the development and evaluations of dierent types of haptic navigation aids. The goal has been to attain a simple user experience that mimics that of the white cane. The idea is that a navigation aid able to do this should have a fair chance of being successful on the market. Theevaluations of the developed prototypes have primarily been qualitative, focusing on judging the feasibility of the developed solutions. They have been evaluated at a very early stage, with visually impaired study participants.Results from the evaluations indicate that haptic feedback can lead to solutions that are both easy to understand and use. Since the evaluations were done at an early stage in the development, the participants have also provided valuable feedback regarding design and functionality. They have also noted many scenarios throughout their daily lives where such navigation aids would be of use.The thesis document these results, together with ideas and thoughts that have emerged and been tested during the development process. This information contributes to the body of knowledge on dierent means of conveying information about surrounding objects non-visually.

    The Development of a Virtual White Cane Using a Haptic Interface2014Licentiate thesis, comprehensive summary (Other academic)
    Abstract [en]

    For millions of visually impaired individuals worldwide, independent navigation is a major challenge. The white cane can be used to avoid obstacles close-by, but it does not aid in navigation as it is difficult to get a large-scale view of the environment. Technological aids have been developed, notably ones based on GPS, but they have not been widely adopted. This thesis approaches the problem from different perspectives. Firstly, current navigation aids are examined from a user-interaction perspective, leading to some design guidelines on how to present spatial information non-visually. Secondly, a prototype of a new navigation aid (the Virtual White Cane) is proposed, and a field trial with visually impaired participants is described. The idea behind the Virtual White Cane is to utilise the intuitive way humans avoid obstacles by touch, and specifically to leverage the experience white cane users already have. This is accomplished by scanning the environment with a laser rangefinder, and presenting the range information using a haptic interface. The regular white cane is easy to use because it behaves like an extended arm, and so does the Virtual White Cane, albeit working at a much greater distance than the regular cane. A field trial with six experienced white cane users was conducted to assess the feasibility of this kind of interaction. The participants carried out a trial procedure where they traversed a prepared environment using the Virtual White Cane. They did not receive extensive training prior to the trial, the point being that if the Virtual White Cane behaves like a regular one, it should be quick to learn for a white cane user. The results show that spatial information can be feasibly conveyed using a haptic interface. This is demonstrated by the ease with which the field trial participants familiarised themselves with the system, notably adopting a similar usage pattern. In interviews that were conducted following the trial procedures, the participants expressed interest in the idea and thought that being a white cane user helped them use the Virtual White Cane. Despite knowing how to operate the system, the participants found locating objects to be difficult. An extended training period would likely have made this easier, but this problem could also be lessened by understanding what model parameters (such as the length of the virtual cane) should be used.

    Abstract [en]

    In its current form, the white cane has been used by visually impaired people for almost a hundred years. It is an intuitive device that helps visually impaired people navigate independently. For people who, in addition to a visual impairment, also have impaired movement, this independence is not as certain. If a wheelchair or a walker is needed, human assistance might be a necessity.MICA (Mobile Internet Connected Assistant) is a computerized wheelchair that has been equipped with a laser rangefinder that can measure the distance to obstacles in the environment. This information has been used to make the wheelhair able to drive on its own, avoiding obstacles, so that users unable to drive a wheelchair themselves are able to use it.The latest addition to MICA - a virtual white cane - allows visually impaired wheelchair users to virtually touch obstacles in their environment, and thus navigate in a similar way to those using a regular white cane. This is accomplished by generating a simplified 3D model based on the data acquired from the laser rangefinder, and sending this data to a haptic device, allowing users to feel the 3D model.The virtual white cane is still in an early development stage. The first test drive of MICA with the virtual white cane (together known as "The Sighted Wheelchair") was performed on 2011-05-10. A short video called "The Sighted Wheelchair" can be found on YouTube.Future work will focus on developing the software that communicates with the laser rangefinder and the haptic device to improve the user experience. Efforts will also be made to overcome the limitations of the laser rangefinder, improving the 3D model.

    Obstacle Avoidance Using Haptics and a Laser Rangefinder2013In: 2013 IEEE Workshop on Advanced Robotics and its Social Impacts: Tokya, Japan, 7-9 Nov 2013, Piscataway, NJ: IEEE Communications Society, 2013, p. 76-81Conference paper (Refereed)
    Abstract [en]

    In its current form, the white cane has been used by visually impaired people for almost a century. It is one of the most basic yet useful navigation aids, mainly because of its simplicity and intuitive usage. For people who have a motion impairment in addition to a visual one, requiring a wheelchair or a walker, the white cane is impractical, leading to human assistance being a necessity. This paper presents the prototype of a virtual white cane using a laser rangefinder to scan the environment and a haptic interface to present this information to the user. Using the virtual white cane, the user is able to "poke" at obstacles several meters ahead and without physical contact with the obstacle. By using a haptic interface, the interaction is very similar to how a regular white cane is used. This paper also presents the results from an initial field trial conducted with six people with a visual impairment.

    Abstract [en]

    Purpose: The purpose of this article is to present some guidelines on how different means of information presentation can be used when conveying spatial information non-visually. The aim is to further the understanding of the qualities navigation aids for visually impaired individuals should possess.Design/methodology/approach: A background in non-visual spatial perception is provided, and existing commercial and non-commercial navigation aids are examined from a user interaction perspective, based on how individuals with a visual impairment perceive and understand space.Findings: The discussions on non-visual spatial perception and navigation aids lead to some user interaction design suggestions. Originality/value: This paper examines navigation aids from the perspective of non-visual spatial perception. The presented design suggestions can serve as basic guidelines for the design of such solutions.

    An Initial Field Trial of a Haptic Navigation System for Persons with a Visual Impairment2015In: Journal of Assistive Technologies, ISSN 1754-9450, E-ISSN 2042-8723, Vol. 9, no 4, p. 199-206Article in journal (Refereed)
    Abstract [en]

    Purpose– The purpose of this paper is to describe conceptions of feasibility of a haptic navigation system for persons with a visual impairment (VI). Design/methodology/approach– Six persons with a VI who were white cane users were tasked with traversing a predetermined route in a corridor environment using the haptic navigation system. To see whether white cane experience translated to using the system, the participants received no prior training. The procedures were video-recorded, and the participants were interviewed about their conceptions of using the system. The interviews were analyzed using content analysis, where inductively generated codes that emerged from the data were clustered together and formulated into categories. Findings– The participants quickly figured out how to use the system, and soon adopted their own usage technique. Despite this, locating objects was difficult. The interviews highlighted the desire to be able to feel at a distance, with several scenarios presented to illustrate current problems. The participants noted that their previous white cane experience helped, but that it nevertheless would take a lot of practice to master using this system. The potential for the device to increase security in unfamiliar environments was mentioned. Practical problems with the prototype were also discussed, notably the lack of auditory feedback. Originality/value– One novel aspect of this field trial is the way it was carried out. Prior training was intentionally not provided, which means that the findings reflect immediate user experiences. The findings confirm the value of being able to perceive things beyond the range of the white cane; at the same time, the participants expressed concerns about that ability. Another key feature is that the prototype should be seen as a navigation aid rather than an obstacle avoidance device, despite the interaction similarities with the white cane. As such, the intent is not to replace the white cane as a primary means of detecting obstacles.

    Hand-held navigation aid for visually impaired using haptic feedback2014Conference paper (Other academic)
    Abstract [en]

    The white cane is used by many visually impaired individuals as the primary aid for avoiding obstacles. In this it is unparalleled, but it cannot provide a large-scale view of the surroundings the way vision does. This makes navigating independently a challenge for the visually impaired. We are developing the Virtual White Cane (VWC), a device that uses sensors and haptic technologies to complement the limited view of the cane. Sensors makes it possible to probe obstacles far beyond the range of the white cane, and haptic feedback is familiar to users of the regular cane. The purpose of this device is to act as a complement to the standard cane, providing information about the surroundings that are beyond the cane's reach. This kind of extended view not only helps in anticipating obstacles, but also to navigate. The presentation will focus on the hardware of the currently developed prototype, in addition to some initial user experiences.

    Att vara förälder till barn med kronisk sjukdom - en litteraturstudie2018Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Att som förälder få uppleva att barnet drabbas av en kronisk sjukdom är en omvälvande händelse för många föräldrar. När ett barn blir sjuk är det oftast en hel familj som drabbas och i vården finns det en utmaning i att möta hela familjen som är i behov av stöd och vård. Syfte var att beskriva upplevelser av att vara förälder till barn med kronisk sjukdom. I denna litteraturstudie utgick vi från Graneheim och Lundmans metod för kvalitativ innehållsanalys med en manifest ansats. Resultat visar att diagnosen och sjukdomen upplevdes svår att hantera. Känslor som sorg, förtvivlan och skuld beskrevs komma i samband med sjukdomen. Känslan av att behöva stöd från hälso- och sjukvården upplevdes viktig av föräldrarna. Familjen upplevde svårigheter att hantera det vardagliga livet och få det att fungera. Mycket oro över det sjuka barnets framtid upplevdes. Fortsatt forskning som handlar om hur hälso- och sjukvården ska kunna ta hand om föräldrar till kroniskt sjukt barn bör utföras. Hälso- och sjukvårdspersonal behöver få tillgång till verktyg som hjälper dem att bemöta föräldrar till kroniskt sjuka barn.

    "Ett sätt att umgås": En kvalitativ studie om upplevelsen av MMO-spel2016Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Massively multiplayer online game (MMO-games) is a digital world where millions of players can meet and play together. This thesis aims to investigate what the players think MMO-games contribute with and how the social interaction is experienced. The questions are: What makes you start to play MMO-games? Why you continue to play? And how is the social interactionexperienced in MMO-games. This study is qualitative and seven interviews were conducted to obtain the respondents experiences of MMO-games. A thematic analysis show the intervieweesbegan to play because of their friends and also continued because of them. In MMO-games, the interviewees have created a wide social network. Games contribute to joy, disconnection and escapism as well as teach the interviewees to communicate with different types of people. MMO-games also facilitate to express themselves online, and provide the opportunity to perform and be the best. But the social interaction is the interviewees main reason for playing. They have acquired several online-friends and some of them can also be compared with offlinefriends.

    How an ERP System Affects Order Processing in a Purchase Department: Case Study: ABB Robotics2013Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The purpose of this thesis is to study how an automatic ERP system is used by a purchase department of after-sales products between a supplier and a customer within a supply chain. It will cover the advantages and disadvantages of the ERP system and also investigate the possibility to for an ERP system to independently manage the purchase process. To be able to connect this to the real world we interviewed the staff at a purchasing department on a multinational corporation. In the study we have found that there are differences between theory and practice when it comes to implementing an SAP system. There are both advantages and disadvantages in theory as well as in reality. We found that most important advantages perceived by ABB Robotics is that it is an integrated system which facilitates the information flow and gives a quick response to the customers. The integration also leads to a simple order processing, something that was seen as an advantage by purchasers at ABB Robotics. On the other hand we found that the main disadvantages was that it is hard to integrate SAP with other systems, it is costly to implement SAP functions in a purchase department and for the moment impossible to integrate with customers outside of SAP.

    Arbetsmiljö, arbetsdelning, utslagning: en studie av städarnas arbetsförhållanden1981Doctoral thesis, comprehensive summary (Other academic)
    Abstract [sv]

    Det dominerande inslaget i det här avhandlingsarbetet är det omfattande empiriska material, som utgör grunden för vår beskrivning och analys av städarbetet och städarnas arbetsförhållanden. I den beskrivning som vi gör strävar vi efter att redovisa en helhetsbild av arbetsmiljön. Den utgår från städarnas egna "vittnesmål" och den är utformad på ett sätt som enskilda städare ska kunna identifiera sig med. En central del i beskrivningen är de besvär som städarna upplever och som de uppfattar som arbetsrelaterade. I analysen försöker vi framför allt belysa de tänkbara sambanden mellan de arbetsmoment som ingår i städarbetet och de besvär som är "typiska" för städarna som grupp. Detta innebär en fokusering på de generella dragen inom städbranschen snarare än på do problem som hör samman med enskilda städare eller arbetsplatser. Vi försöker sätta in städarbetet, dess utveckling och historia, i ett mer allmänt sammanhang. Det innebär aft vi ser städarbetet som en konsekvens av arbetsdelning och specialisering. Arbetsdelningen innefattar bl a en åtskillnad av planering och utförande, av kvalificerat och okvalificerat arbete, av produktivt och reproduktivt arbete, av män och kvinnor. De metoder som vi använt för att samla in data om arbetsmiljön, dess beskaffenhet och dess inverkan på människan har utvecklats utifrån de mål som vi velat uppnå med undersökningen. I praktiken har detta inneburit att vi kombinerat flera olika metoder, såväl traditionella som förhållandevis okonventionella sådana. Såväl valet av forskningsområde, problem och metoder som beskrivningen och bedömningen av arbetsmiljön grundas ytterst på värderingar (som i det här fallet rör synen på människan och på samhället). Det är därför väsentligt att redovisa de kriterier/arbetsmiljökrav som vi, mer eller mindre outtalat, bedömt arbetsmiljön enligt och de mål som ligger till grund för våra förslag till förändringar. Våra utgångspunkter har varit att arbetsmiljön åtminstone ska motsvara de krav/kriterier som kan härledas ur den gällande lagstiftningen. P& samma sätt grundas våra förändringsförslag P& målet att tillgodose de nämnda kraven. Dessa karv kan uppfattas som förhållandevis defensiva. Förklaringen till vår måttfullhet är att vi uppfattar bristerna som så stora att även förändringar som endast leder till en "minimistandard", skulle uppfattas som stora förbättringar. Vi menar att skillnaderna mellan arbetsmiljömålen (sådana de uttrycks i lagen) och den verklighet som städarna arbetar i är mycket stora. Innebär detta att målen är orealistiska? Eller är det medlen för att uppnå målen som är otillräckliga? Går det överhuvudtaget att lagstifta bort den dåliga arbetsmiljön? Vi besvarar inte dessa frågor i den här avhandlingen. Däremot gör vi en redovisning av hur lagstiftningen kommit till, hur den är tänkt att fungera, vilka reaktioner som den mötte vid införandet och något om hur den utfallit. Utifrån våra erfarenheter bl a från den här undersökningen, menar vi att lagstiftningen aldrig kan vara ett tillräckligt villkor för uppkomsten av en "god arbetsmiljö". Att förändra arbetsvillkoren är i stället ytterst en fråga för arbetarna själva och deras intresseorganisationer. P& samma sätt är det dessa som måste fastställa mål och medel i förändringsarbetet. Vår roll som forskare blir därmed att bidra till ökade kunskaper om arbetslivet och att göra dessa tillgängliga för dem som arbetar. Detta ställer stora krav på valet av relevanta forskningsområden. Vår beskrivning och analys av städarbetet utmynnar i en skissartad beskrivning av hur städarbetet skulle kunna förändras. Om detta förslag har en önskvärd effekt kan endast prövas genom praktiska försök. Vi hoppas att det material som vi redovisar ska stimulera till sådana försök eller till utarbetande av bättre idéer. Men detta är ju i och för sig en helt annan historia ...

    Gender stereotyping in television advertisements: a case of Austrian state television2007Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Using content coding analysis, the current study examines sex-role portrayals in Austrian television advertisements. 129 Austrian advertisements were recorded in May 2005, and subsequently analyzed by employing established coding categories. The findings indicate that gender stereotypes in Austrian television advertisements exist in some aspects. For instance, women are underrepresented both as central characters and narrating voiceovers. Men, on the other hand, often play a dominant role and promote masculine products. However, this study also presents results that go against the grain to traditional gender stereotyping, as males and females are found to be equally represented in dependent roles, as well as in occupational and domestic settings.

    Vårdpersonals upplevelser av att vårda personer med demenssjukdom2016Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Demenssjukdom är en av de mest vanligt förekommande sjukdomarna och det är främst äldre människor som drabbas. Detta kommer att leda till att antalet personer med demenssjukdom kommer att öka och deras komplexa sjukdomsproblematik kommer att leda till ökat behov av sjukhusvistelse och särskilt boende. Syftet med denna litteraturstudie var att beskriva vårdpersonals upplevelser av att vårda människor med demenssjukdom. En systematisk litteratursökning av vetenskaplig studier genomfördes inom området, vilket resulterade i tio studier som svarade på syftet. Studiernas innehåll analyserades med en kvalitativ manifest innehållsanalys med en induktiv ansats, som resulterade i fyra kategorier: Att vårdandet kan vara en utmaning, Att både ha kunskaps- och tidsbrist, Att vårdmiljön inte är utformad för personer med demenssjukdom och Att ha en god relation och kommunikation har stor betydelse. Studiens resultat diskuteras främst utifrån personcentrerad vård och hur ett personcentrerat förhållningsätt skulle kunna etableras inom vården av personer med demenssjukdom, i syfte att stärka personen med demenssjukdom utifrån dennes unika förutsättningar. Slutsatsen belyser vikten av att arbeta personcentrerat inom demensvården och att kunskap om demenssjukdomar kan underlätta svåra situationer.
