Background: The population of the world is getting older and in the year of 2020, 1.2 billion people will be 60 years or older. A common health complaint affecting the quality of life in elderly persons are sleep difficulties. Physical activity is claimed to improve sleep quality and the maintenance of a normal circadian rhythm. Several studies have shown positive effects of physical activity on sleep quality, still the evidence of physical activity as sleep-promoter is insufficient. Aim: The aim of this study was to investigate associations between physical activities and sleep quality in persons ?60 years of age.

Examensarbetet behandlar ett brotvärsnitt som inte entydigt kan betraktas som ett balktvärsnitt eller plattvärsnitt. Med de måttdefinitioner som används vid broprojektering ska en plattkonstruktion ha en bredd som är fem gånger höjden, annars ska konstruktionen ses som en balk där även balkens längd definieras att vara större än tre gånger höjden. Brotvärsnittet som studeras i detta examensarbete kan alltså definieras både som ett plattvärsnitt och som ett balktvärsnitt. Målet med arbetet är att undersöka om det är möjligt att finna en metod att konstruera denna typ av tvärsnitt som befinner sig i gränslandet mellan två definitioner. Skillnaderna mellan en plattas och en balks verkningssätt ligger i att plattan antas bära last i två riktningar medan en balk enbart bär last i en riktning.Examensarbetet är genomfört i sammarbete med WSP Bro- och vattenbyggnad i Örebro, som konstruerade en bro med just detta tvärsnitt.

Heart failure is the most common reason to hospitalization among persons over 65 years old. Self-care is an important part in the treatment of heart failure, but poor information and knowledge limits the ability of self-care and increases the risk of admission to hospital.The aim of the study was to investigate what information patients with heart failure describes that they receive from health care personal, how information is perceived, who provides the information, and on what occasions it is given. The aim was also to investigate whether patients' perception of knowledge about heart failure increased after hospitalization.The study is cross-sectional study with a descriptive design. A consecutive selection was used. A questionnaire was filled in by 28 participants.The study has shown that patients with heart failure largely experience information about heart failure inadequate.

The aim of this master?s thesis is to investigate how adults describe their individual reading experiences, on the basis of their own reflections by keeping a reading diary. Reading diaries kept during two months and a qualitative questionnaire for each of our nine motivated and advanced adult readers, were analyzed by using qualitative content analysis. The study was carried out on the Internet. The theoretical framework that served as a point of departure is Ross? and Chelton?s model for the process of choosing a book to read for pleasure, Nussbaum?s moral philosophy and thesis ?Reading for life? and Mukar?ovský?s theory of the aesthetic value.

The purpose of this essay is to illustrate the importance of the school library in a selected junior high school. My investigation is based on both theoretical and empirical studies. The aim of the theoretical part is to create a platform and refer to thoughts, roles and laws concerning the activity of the school library. The empirical investigation consists of two parts: questionnaires among students and teachers, plus interviews with students, teachers, headmaster, school librarian and the management of education. Everybody shows a positive attitude towards the school library and considers it important for the students exams.

Forest enterprises have always searched for ways to improve efficiency. For the past few years there has been an emphasis on stock-keeping levels. Increased demand for fresh round timber and the need to decrease the amount of tied-up capital has made the forest industry reduce its inventory levels. This has brought on a higher demand on the timber supply from the forest management districts concerning both delivery in time and assortment output. As a result, the flow of timber has fluctuated a lot with serious consequence for the timber supply during 1994.

Den här uppsatsen undersöker hur andelen deltidsanställningar inom den kommunala verksamheten påverkar kommunernas personalkostnader. Flera regressionsmodeller har använts på ett material bestående av Sveriges samtliga kommuner mellan åren 1998 och 2006. Resultaten har visat att en kommun som minskar andelen deltidsanställda med tio procentenheter beräknas sänka sina personalkostnader med ca 1200 kr per kommuninvånare och år. Modellerna är signifikanta även när de kontrolleras för autokorrelation och relativt hårda antaganden om orsaksriktning och effektens fördröjning.Även deltidsanställningarnas inverkan på kvaliteten i den kommunala verksamheten har studerats. Trots svårigheterna att mäta kvalitet, tyder resultaten på att en minskning av andelen deltidsanställningar förväntas förbättra kvaliteten.Sammantaget visar resultaten att kommuner som erbjuder sina deltidsanställda möjlighet till heltidsanställning kan göra mindre ekonomiska vinster utan att försämra verksamhetens kvalitet.

This final thesis was performed at Ericsson in Gävle between April and June of 2008. Ericsson is a world leading manufacturer of radio base stations (RBS), which handles mobile phone traffic with 2G and 3G technology. The main purpose of this study is to examine if two different types of products (RBS and site material) should have different terms and conditions, today the terms and conditions are the same for both types. During the course of our study we have tried to think of the terms reliability, validity and generalization. The intention in doing that was to keep the thesis at a high academic level. To name an example of this we have tried to keep our minds at an objective level during the interviews and informal conversations.

Syftet med denna studie var att undersöka vilken inställning elever och idrottslärare har till att använda mobiltelefoner, film och bloggar i samband med undervisningen i ämnet idrott och hälsa. Urvalsgruppen bestod av 225 grundskole- och gymnasieelever samt 5 lärare fördelat på 5 skolor i Skåne. De metodologiska tillvägagångssätten utgjordes av intervjuer med lärarna och en enkätundersökning med eleverna. Resultaten har analyserats med utgångspunkt i Roger Säljös vidareutveckling av Lev Vygotskijs sociokulturella perspektiv på lärande, samt Thomas Ziehes teori om kolliderande livsvärldar. Vidare har resultaten ställts i relation till tidigare resultat inom forskningsfältet.

The habits of living are seen as important factors for public health, and are related to the primary socialization. Exercise and food habits are two main factors for development of health or ill health and are both related to the overweight epidemic. The overweight increase among children and youth has been given particular attention. The aim of this study is to examine how 15 year olds Body Mass Index, food- and exercise habits are connected to each other and also how they are related to socialization. The study is a cross sectional survey among 208 pupils in ninth grade, Kristianstad.

The purpose of this study has been to examine online travel magazines as an information source and as a virtual service scape. The traditional travel magazines are facing a change due to the technological development and the web has become an important platform for both customers and companies. The virtual service scape opens new opportunities for interaction and we found a great interest in examining which possibilities and limitations travel magazines are facing. This study is based on a qualitative approach because we wanted to gain a deeper understanding and a complete picture of our chosen subject. We have completed six interviews; three of them were consultants, one publishing director, one editor and a research student.

The survey was aimed at high school students in Kalmar and weredistributed and collected on-site at the schools. What was remarkable among theresponses was that young people largely had access to a morning newspaper athome and said that they would consider subscribing to one in the future.

Purpose: Social media is a global phenomenon that has developed from an opportunity of contact between people, into a platform for contact between organizations and people. This essay aims to investigate the public relation strategies of one organization on a popular social network.The main question that this study aims to answer is how the travel agency Ving chooses to create and preserve relationships to the public on Facebook in order to maintain a good reputation. Asub-question explores whether any patterns exist in Ving?s approach of interaction with its stakeholders.Method/Material: This study consists of a quantitative content analysis in which the interaction between the organization and the audience has been studied. Posts published by the public as well as replications from Ving have been categorized and then analyzed using two analytical models.

The thesis presents an optimally designed kinematic structure for a new 6-DOF haptic devicebased on TAU configuration. The configuration of the TAU-2 proposed by Suleman Khan andKjell Andersson [1] was modified and its mobility was verified by using Grübler criterion tohave a 6 DOF. Analytical kinematic models for the inverse and forward kinematics weredeveloped for the haptic TAU configuration to determine a set of optimal design parameters.Kinematic performance indices such as volume of the workspace, kinematic isotropy and payload index, were defined based on the singular values of the Jacobian matrix. The Jacobianmatrix was scaled to homogenize the physical units. The Jacobian matrix dependent on theposition and orientation of the end-effector gives local isotropy and pay load index, so globaldesign indices were defined, which represent the performance of the mechanism in the wholeworkspace.

Syftet med detta examensarbete var att skapa ett serverprogram i en enkortsdator som arbetar i realtid för att kunna hjälpa människor att köra mer ekonomiskt och miljövänligt i deras vardag.Detta var ett av målen ställda av produktbeställaren Ziggy Creative Colony. Ett mer långsiktigt mål från beställaren är att datorn skall installeras i en bil och kopplas till bilens on-board diagnostic-II (OBD-II)-uttag. Datorn ska sedan, via OBD-II, kunna samla information som till exempel hastighet, acceleration och bränsleflöde från bilens engine control unit (ECU). Serverprogrammet ska bearbeta denna information som sedan kommuniceras och visualiseras till bilföraren via en native mobilapplikation.Serverprogrammet byggdes i en linuxbaserad dator: Raspberry Pi och döptes av oss till Car-Pi. Car-Pi designades enligt arkitekturmönstret Model-View-Controller (MVC) som gör det lätt att underhålla, vidare-utveckla och implementera programmet av produktägaren, Ziggy Creative Colony, i framtiden.
