Ansökan om körkortstillstånd via Internet

Länsstyrelsen i Stockholms län hade en projektidé som gick ut på att det skulle skapas en Internetbaserad ansökan för körkortstillstånd med behörighet B, inklusive hälsodeklaration. Även en optiker skulle kunna fylla i ett synundersökningsformulär via webben. Dessa skulle sedan knytas ihop för behandling av den Länsstyrelse där den sökande bor. Alla personer som skall använda tjänsten måste inneha ett personligt medborgarcertifikat som används för elektronisk signering av ansökan. Optikern behöver ett företagscertifikat för att identifiera sig. Vi utvecklade två interaktiva användargränssnitt samt ett gränssnitt där administratören kunde hantera all data som inkommit.

Utformning av ett materialflödessystem anpassat för HSP-Gripens produktion

Like many small-time companies there is a need to improve the flow of materials at HSP-Gripen AB. The company develops and manufactures hydraulic-powered grapples for the machine- and forest industry. By mapping the material flow in the current production and gathering necessary data, suggestions on how different parts of the production could be controlled is presented in this dissertation. This has been achieved by the study of relevant scientific literature. The suggested ways of controlling the production consist of 2-bin systems, hybrid material flow system as well as a cyclic product-planning.

E-handel : Vilka faktorer styr konsumentens köp över Internet och då med fokus på hälsokostbranschen?

In today?s IT-community, consumers use the internet in a increasing rate to find information or to purchase products and services. This has led to a growth in the market, but also a greater competition between e-stores and web shops. To separate yourself from the masses has become more important, the question is; what strategy should the IT-salesman use? The meaning of this scientific study is to find and focus on witch the primary factors/aspects are, that controls and is the very foundation for the consumer making a purchase, by using the internet.

Evidens som hegemonisk strategi i socialt arbete : en diskursanalys av den språkliga praktiken i en barn och ungdomsgrupp som arbetar med ett strukturerat beslutsstöd

This thesis describes how social work language practice circulates around the implementation process of an evidence based structured assessment tool – Savry. The purpose is to examine and understand the social workers language practice in a working group that uses this structured assessment tool in their work with youth. The purpose is also to look for dimensions of identity in terms of discourse. The ontological viewpoint is post-structuralism where language is in focus. The theoretical framework is discourse theory based upon the work of Ernesto Laclau and Chantal Mouffe.

Bestämning av lägsta luminans för utrymningsskyltar

This report is based upon an experimental study of exit sign luminescence in different environments. The purpose is to evaluate the lowest luminescence of an exit sign, based upon Swedish regulations. Scientific experiments have been conducted in a controlled environment, where exit sign luminescence was graded by an evaluation group. The results of these have been verified by similar experiments that took place in two department stores. The final result of the study is guidelines for appropriate exit sign luminescence in different environments..

Miljökommunikation i dagspressen : En diskursanalys av hur SvD och DN framställer miljöfrågor

The starting point of this study is that the news media in general strongly influence which topics determine the public agenda by their choice of what is considered newsworthy. The study is based on articles from two major Swedish daily newspapers, Svenska Dagbladet and Dagens Nyheter. The aim of our thesis is to establish how the environmental public debate as portrayed in the newspaper corresponds to the environmental discussion within the scientific (subject matter expert) field, that is taught by the academic institutions, or if the two materially differ. The environmental communication discourse at the academic institutions advocates ?episodic? formation as the driving force behind transformation of attitudes and behavioral preconceptions. This episodic formation is aimed at incentivizing change by creating intimacy to the incident by linking cause and consequence to the individual citizen instead of to society as a whole.

Anhöriga i sorg. Sjuksköterskans stödjande roll till anhöriga i sorg.

Death is the only experience we know we will come across in our lives. Yet it is so difficult to speak about death and the sorrow before and after death occurs. The aim of this literature study was to find out how as a general nurse one can help relatives to handle their situation in mourning. The question was: How does the nurse feel when confronted with mourning relatives? What measures and caring should the nurse take to alleviate the handling of the relatives in mourning? After scrutiny and critical analysis of ten scientific papers, some common denominators have remained.

Effekten av frukostens glykemiska index på energiintag hos barn och ungdomar

Sahlgrenska Academyat University of GothenburgDepartment of Internal Medicine and Clinical NutritionTitle: The effect of the glycemic index of breakfasts in energy intake inchildren and adolescentsAuthor: Charlotte Olofsson, Cornelia Johansson and Maria NordbeckSupervisor: Fredrik BertzExaminer: Ingrid LarssonProgramme: Dietician study programme, 180/240 ECTSType of paper: Examination paper, 15 hpDate: May 16, 2013Background: The glycemic index (GI) and it´s effect on energy intake is a debated subject.Research has been done whether food with lower GI decreases hunger and lowers energyintake, which could be an effective tool to prevent overweight in children and adolescents.Breakfast eating is successful for maintaining a healthy weight and it´s therefore interesting tosee if the quality of the carbohydrates matters.Objective: To evaluate the scientific evidence regarding the effect of GI of breakfasts inchildren?s and adolescents energy intake.Search strategy: To find relevant articles, a systematic literature search was made in thedatabases PubMed, Scopus and Cochrane. Search terms that were used were: breakfast,breakfast quality, children, glycemic index, energy intake, obesity.Selection criteria: Randomized controlled trials and cohort trials, breakfast eatingindividuals, children and adolescents under 18 years old, reported glycemic index. Outcomemeasurements: Energy intake.Data collection and analysis: Six original articles met the inclusion criteria and werereviewed by the SBU audit template for randomized and controlled studies. There after onearticle was excluded because of very low quality of the study.

Hållbarhetslivscykelanalys på kakel och klinker : Analys av vägen från vagga till grav ur ett hållbarhetsperspektiv

In this report two Sustainability Life Cycle Assessments are carried out for two types of tiles for Riksbyggen, to contribute to a sustainable urban transition. Sustainability Life Cycle Assessment involves performing a life cycle assessment based on four principles based on scientific research and presented by the non- governmental, non-profit organization, The Natural Step. The principles concern raw materials, chemically produced substances, degeneration of nature and social conditions.Origin of products, manufacturing sites and manufacturing procedures were initially completely unknown and much of the work has consisted of finding the entire cycles, understand manufacturing processes of ceramic tiles and evaluating what materials and what type of energy sources that are required for the production. A socially sustainable perspective has been of high relevance alongside an ecologically sustainable perspective.The report begins with the basic underlying facts and the purposes of this investigation and that the reasons why Sustainability Life Cycle Assessments are carried out are to provide Riksbyggen and the own workers with documents presenting Riksbyggens ideas regarding sustainability and to hopefully get the ideas further down in the supply chain. The methods used to fulfill the investigation are presented and scientific facts about LCA and ceramic building materials are reviewed.

Peer-to-peer som företagslösning

Problemområde: Idag är användandet av peer-to-peer (P2P) - applikationer såsom KaZaa, ICQ och Seti@home utbrett bland privatpersoner. Användningen inom företag är dock ännu i sin linda. Vi kommer därför i den här uppsatsen utreda om ett eventuellt införande av P2P- teknik i ett företagsnätverk ger några fördelar jämfört med en klassisk Client/Server-lösning. Hypotes: Arbetet bygger på hypotesen: ?En P2P-lösning ger fördelar för företaget jämfört med en Client/Server-lösning? Genomförande: För jämförelsen mellan P2P och Client/Server definierades och jämfördes fem områden: Säkerhet, Användbarhet, Tillgänglighet, Bandbredd samt Utrustningskrav. Slutsats: Inom områdena Användbarhet och Tillgänglighet ger en P2P-lösning klara fördelar, däremot inom områdena Säkerhet och Bandbredd visar Client/Server- lösningen istället klara fördelar. Området Utrustningskrav är oavgjort då det inte finns någon märkbar skillnad på lösningarna. Säkerhetsproblemen är P2P-teknologins akilleshäl och det problem som är mest troligt att stoppa stora investeringar i framtiden om det inte löses. Slutsatsen av vår jämförelse blir sålunda: För ett företag som redan har ett existerande Client/Server-nätverk är det inte någon idé att helt byta system, däremot kan det vara av intresse att introducera en applikation som möjliggör skapandet av så kallade Virtuella Nätverk. För ett helt nytt företag kan skapandet av ett P2P-nätverk vara ett väl så intressant alternativ till Client/Server.

Feta kontra magra mejeriprodukter vid primärprevention av hjärt- kärlsjukdom. En systematisk översiktsartikel

Sahlgrenska Academyat University of GothenburgDepartment of Internal Medicine and Clinical NutritionAbstractTitle: Whole fat versus low-fat dairy products for primary prevention of cardiovascular disease. A systematic review.Author: Josefine Lindqvist, Robin Järnmark, Mathilde OhlinSupervisor: Mette AxelsenExaminer: Anna WinkvistProgramme: Dietician study programme, 180/240 ECTSType of paper: Examination paper, 15 hpDate: 2014-04-09BackgroundResearch indicates that dairy products seems to have a protective impact on the incidence of cardiovascular disease regardless fat content. Paradoxically the Nordic nutrition recommendations recommend an exchange of full fat dairy product to low-fat dairy products.ObjectiveThe aim of this review is to investigate whether the variation in fat content of dairy products have any bearing on the onset of cardiovascular disease. With regard to common risk markers for cardiovascular disease the outcome measures hypertension, hyperlipidemia and weight gain is examined.Search strategyThe searches were made in the databases Medline (23/1-14) and Scopus (6/2-14).Selection criteriaRestrictions: Human Studies, Adults, Randomized Controlled Trials, English.Data collection and analysisTwo RCTs were included. Validation of the separate studies was performed with SBU's review template for individual studies and GRADE was used for summarizing the evidence of outcome measuresMain resultsThe two included studies examined the outcome measures blood pressure, weight and blood lipids.

Prestandajämförelse mellan Amazon EC2 och privat datacenter

Publika moln har sedan några år tillbaka blivit ett alternativ för olika företag att använda istället för lokala datacenter. Vad publika moln erbjuder är en tjänst som gör det möjligt för företag och privatpersoner att hyra datorkapacitet. Vilket gör att de inte längre behöver spendera pengar på resurser som inte används. Istället för att köpa en stor andel hårdvara och uppskatta hur stor kapacitet som man behöver kan man nu istället så smått börja utöka efter behov eller minska ifall det önskas. Därmed behöver företag inte spendera pengar på hårdvara som inte används eller har för lite datorkapacitet, vilket skulle kunna resultera i att stora batcharbeten inte blir färdiga i tid och i och med det kan företaget förlora potentiella kunder.

Beröringens betydelse för patienters upplevelse av smärta, oro och känsla av välbefinnande

Touch that is performed in a sensitive and gentle way can be a good complement in caring. To be stricken with illness can involve that the individual feels powerlessness and to have no control over the own body. This could lead to both psychical and physical suffering. To strength health is one of the nurses' responsibilities and to touch can be one way. The aim of the study was to describe patients' experience of the effects of touch.
