Kommunikation hos respiratorvårdade patienter : Upplevelser hos patient och vårdpersonal samt analys av samtal med och utan röstgenerator

?Studies have shown that patients receiving mechanical ventilation in an intensive care unit (ICU), who are entirely dependent on the nursing staff, often experience frustration due to a temporary loss of the voice source. Limited communication is an important factor contributing to patient discomfort. Nursing staff also report communication as frustrating and difficult.The aim of the present study is to introduce a neck-type electrolarynx as a communication aid in an ICU, to study the nursing staff experiences of communication with tracheotomized patients receiving mechanical ventilation, and to examine the patient´s experiences regarding communicative abilities. Communication between a ventilator treated, tracheotomized patient and members of the nursing staff was recorded and analyzed according to principles of Conversation Analysis (CA).The results show that several members of the nursing staff experience difficulties communicating with tracheotomized patients receiving mechanical ventilation.

Att skapa en konceptdesign av en webbplats för ett evenemang : Att ta fram en design av en webbplats med en grafisk identitet ur ett marknadsperspektiv

Internet and social media have opened up new possibilities for companies and organisations tocommunicate their brand. It only takes a few seconds to communicate the message of a website to theuser. This indicates the importance of having the intended message of the website communicated clearlyin order to give the user a correct impression of the company or the organisation. When it comes to theconcept design of a website, it?s important that all different parts is presented uniformly.

Ventilhus för salivsug i dentalutrustning

The purpose of this work is to find out if the suctionvalve to the salivaejector for dental equipment in a simple way can be improved or if a new design is needed. The result of the examination of the suctionvalve shows that the friction between the piston and the seal is high and that this causes the valve in a few cases sheaves. The study concluded that only small changes in material or detail, improve the component..

Utveckling av hjulhållare för cykelhållare

This report is a bachelor thesis work within the field of Product Development and is also an assignment for Thule Sweden. The work has been performed by Niclas Tjäderborn and Christian Holm, students at the Mechanical Engineering Program with major in Product Development and Industrial Design at Jönköping School of Engineering during spring the semester of 2009.The thesis work concerned the development of a new wheel holder for bike carrier for Thule Sweden. The background to the project was that the initiator wanted a more user friendly wheel holder with better design than those available on the market. The wheel holder is able to be implemented on one or several of Thule?s current wheel holders.

Upplyst trapphus

The purpose of this thesis was to increase the understanding and discuss safety aspects in two stairwells on Nyforsgatan in Eskilstuna, where the buildings were built during the years 1965-1975. I have presented a proposal for improvement through lighting. I have through different methods, such as surveys, interviews, literature studies and observations, come to a conclusion: that there are opportunities for improvement through better lighting that allows orientation in space and creates a nice atmosphere which will remove the feeling of not being safe, e.g. dark corners and shadows. It has been an exciting process to gather enough of facts to rely on and to develop the lighting design for the environments.

Northern Stories. Ett narrativt videokoncept

Northern Stories is a narrative video-project, mixed between how to work with the movieformat and the programs involved. As well as the complexity of how it can be to work in collaboration with a company and an investigation in how to evolve my design process. This from a designer?s point of view and with the intention to produce a finished product..

ERP-implementation och processkartläggning : En studie om implementering av ett ERP-syste, och vilka fördelar en processkartläggning kan ge för kravställandet.

To implement an ERP-system is not an easy process. The success of the implementation depend on many different variables. The most important one is perhaps the requirement process, to define what the organization wants and expects from the system. In this study, the advantages of a process mapping are examined, in relation to the phase where the requirements are expressed in an ERP-implementation. The conclusion is that a process mapping generates an increased communication with the supplier of the ERP-system, hence the business knows their processes and thereby what they want from the system.

Undersökning av Mekaniska Problem med hjälp av Datoralgebra

When investigating mechanical problems it is often more convenient to deal with scalars rather than vectors. In this project methods stemming from the field of analytical mechanics, which lets one derive the equations of motion using scalar quantities instead of vectors, have been used. Two mechanical problems were investigated, a double pendulum with a spring and particles orbit in a sphere. The equations of motion of the two systems were derived with the assistance of computer algebra, using Maple and the external package Sophia. The systems were investigated with regard to periodicity and conserved quantities..

Konstruktion av säkerhetslagerför svänghjul

This thesis is the result of the investigation and solution of a mechanicalproblem regarding flywheel malfunctions. A flywheel is, in short, a devicethat relies on a rotating object?s moment of inertia to store energy overshort time spans. This project is part of the development of a fourthflywheel prototype at the division for electricity at Uppsala university,which uses magnetic levitation to keep a hollow cylinder rotating at veryhigh speeds inside a vacuum chamber. Should the magnets fail however, orsome other error occur that leads to an uncontrolled state of rotation, thecylinder needs to be stabilized mechanically by a device usually referredto as ?back-up bearing?.

Särskild planering för elever med fallenhet för matematik? : Eller för alla elever?

A current issue today is to try to implement creative design as a way to solve wicked problems in scientific contexts such as HCI. Since the problems are wicked, they have no given solution which makes the traditional methods inadequate. In these cases, creative design can be an alternative. Creative design is not used in scientific contexts because it is viewed as something unaccountable.In this essay we argue that creative design not necessarily have to be unaccounted. We discuss various views of creative design and translate theory to a practical context.

Epoxidised linseed oil as hydrophobic substance for wood protection : technology of treatment and properties of modified wood

Public concern about the release of toxic compounds from wood-based products drives legislation towards enforcing industries to find and use more sustainable solutions for wood treatment. Plant oils are good alternatives to treat wood, minimizing or even neutralizing the impact on the environment. Wood modification with epoxidised linseed oil (ELO) and acetic acid as catalyst has proven a suitable method to impregnate and protect wood. However, the mixture presents a serious inconvenience because of the quick polymerization of the ingredients that limits its practical application. Therefore, this study was designed to evaluate an alternative method using a two-step process which bypassed the problem above.

Gapet mellan teori och praktik i pappersprototypande : en studie i diskrepans mellan det ideala arbetssättet akademin förespråkar och hur praktikern faktiskt arbetar

This study presents an alternate viewpoint to the strive to overcome the gap between research and practitioners within paper prototyping in interaction design. Earlier research identifies three aspects of this gap, which is:Practitioners being unaware of interaction design methods and theoriesPractitioners being aware, but choosing not to apply these methods and theories, due to time, budget and constraints of labourPractitioners and research having different perspective on similar design issuesOur study was done by carrying out qualitative interviews with interaction designers based on two digital design bureaus. One of the bureaus has an expressed link to research: the other has not. Our hypothesis is that the gap would manifest as a difference in work practice between the two bureaus.Our study shows that the two bureaus have similarities in work practice and that this work practice is based on scientific methods and theories, but is adapted to fit the client and/or the project. We conclude that the overcoming of the gap might not be necessary.

Shooting Target - Design : Product Development

The project has involved the development of two kinds of shooting targets in partnership with Marcus Bergkvist and Christopher Åkerblom. The project from the client was divided into two parts. This thesis discusses solutions for hands-on transport, development of tripods and an overall design. The second thesis affect resetting systems for the products.The work was done with a process and methodology based on design perspectives. This process has involved the search of relevant data which has provided the platform and opportunity for appropriate and purposeful design work.Concept development has been done using hand sketches and Photoshop, where a simple visualization of different concepts for the tripods has been produced.

Torkning och pelletering av organiskt hushållsavfall - en konstruktionslösning

The research in this paper aims to producing a home version machine thatcan dry and make biological waste into compact pellets. This product ismade primarily for those who want to improve the environment and reducethe energy consuming process of separating the biological leftovers fromother waste in the large processing plants and save money due to reducedpickups of waste. Since there is no commercially available product thatdoes what we want to achieve we had to start from the beginning with boththe design and the mechanical aspects. The result is a machine, that fits inour homes, and in an easy and inexpensive way reduces the amount ofbiological waste that needs to be collected by the public wastetransportation system. This is done without reducing any of the energy inthe waste and it can still be used to compost or by large-scale plants that usethe waste to make electricity.

Hållbara projekteringsverktyg : Från byggnadsinformationsmodell till simulering ? en utvärdering av Revit och Virtual Environment

This study examines the use of building modeling and energy simulations in the design process  of  a  building.  The  take-off  point  is  the  notion  of  energy  simulations  being needed early and throughout the building design process, and that the lack of energy simulations may be explained by the fact that they are time consuming and therefore often too expensive. A greater interoperability between software tools used by relevant disciplines,  such  as  the  architect  and  the  energy  specialist,  would  create  smoother workflows, which would reduce this cost and open up for more frequent and iterative energy  simulation  processes.  The  study  is  an  assessment  of  the  modeling  tool  Revit and  the  simulation  tool  Virtual  Environment  and  whether  they  can  create  smoother workflows, and make leeway for a more frequent use of energy simulations throughout the  design  process.  It  also  investigates  the  limitations  of  what  can  be  examined  by simulations in Virtual Environment. This will hopefully help clarify the future role of energy  simulations  in  design  processes.  The  method  is  a  trial  by  error  approach  of testing the two software tools by building and simulating a model. The results of these tests  show  that  the  workflow  is  not  optimal  (and  therefore  time  consuming)  for frequent  and  iterative simulations  throughout the  design  process,  but  it  also  reveals some  great  possibilities  of  what  can  be  performed  with  these  two  powerful  tools  at hand.  Further  development  with  regards  on  platform  independency  of  the  building information  model,  including  seamless  exporting  and  importing,  seems  necessary  to strengthen the future role of energy simulations..
