Analys av arbetsmiljö vid kokarpåsvetsning samt förslag till förbättringar.

Denna rapport är ett inledande steg mot att förbättra arbetsmiljön för svetsare vid påsvetsning med Uddcomb Metoden i massakokare. Syftet med rapporten är att analysera problemet med värme och dålig luft samt förklara hur och varför problemet uppstår. I arbetet ingår även att ta fram olika lösningar för att slutligen hitta ett komplett system för ventilation och kylning. Den föreslagna lösningen består av ett integrerat kylsystem och ett koncept med mindre fläktar, kallade torpeder, som monteras på arbetsplanen vilka driver ut varm och smutsig luft snabbare ur kokaren. Den föreslagna lösningen utreds även ur ett ekonomiskt perspektiv.

Nostalgiska Ljud

Det finns ljud som är på väg att försvinna i takt med teknologins utveckling. Dagens ungdomar har aldrig hört ljud från den äldre teknologin, som den äldre generationen har fått växa upp med såsom skrivmaskinen, modemet m.m. Dessa produkter gav ifrån sig ett speciellt ljud som numera inte hörs lika mycket idag. Men vad händer när tekniken utvecklas till den grad att ljud blir en säkerhetsfråga? Förutom teknikljud finns det ljud från förhistoriska och nyligen utdöda djur som forskare har lyckats återskapa genom studier av kvarlevornas anatomi.

Ronningsgift

This thesis examines the sheep shed called Ronningsgift, and its historical functions and geographical location. The study aims to make a comprehensive gathering of the existing knowledge and to shed light on new theories about the history of Ronningsgift. This is done through desk research including literature and archive search, as well as an investigation and description of the construction and materials, and an interview. Further, I got the opportunity to take part of the results of two C14 samples from Ronningsgift. The literature and archive search shows that the most common theory of the historical function is as a guest house (g?ststuga/h?gstuga) or more traditionally called, Malst?ue/Malsteuvu.

Filmproduktionsprocesser : En jämförande studie om att filma analogt kontra digitalt

The art of producing films have been around for more than a century and the technology just continues to evolve. But although much has happened in 100 years, there are also processes, theories and practices that look the same now as then. I write this thesis because I want to find the differences between the analogue and the digital way of production. This study is based on a qualitative approach because my ambition is to seek the views concerning film production processes. The advantages of analogue film is that it contains more information than the digital formats and that it has a more cinematic style.

Aktivitet i ingenmansland : En undersökning av sökbeteendet bland arbetslösa sjukskrivna

Absenteeism due to sickness has increased during the last few years and has become a serious problem of society in Sweden. Among the sick-listed there is a group that apart from being sick are also unemployed.The aim of this paper was to study if and how the unemployed seek employment when they are sick-listed. Central questions have been if the unemployed seek employment while they are sick-listed? To what extent do they seek employment? Which methods do they use and what demands do they make of their prospective jobs?The survey was based on a quantitative method and the answers that 100 unemployed sick-listed in the northwest of Skåne, Sweden gave to questionnaires. The result was analysed using a bivariate analysis in order to find patterns or obvious differences.The result showed that more than half (60 percent) of the people in the survey group used up to an hour or more per week to search for or apply for work.

Lättläst information i e-förvaltningens tid : En studie om lättläst information när myndigheterna satsar på webben

The overall aim of this thesis is to examine how Easy-to-Read information, used by governmental agencies, facilitates and limits the field of possibilities for the intended recipient, based on the information.This, in anera of e-government.The theoretical framework is based on two Foucauldian concepts governmentality and discourse analysis. Representatives from five Swedish governmental agencies have been interviewed and the results have been analyzed based on the following questions: (1) How do the representatives construct the category Easy-to-Read? (2) How do these representatives construct the recipients of Easy-to-Read? In order to broaden the understanding of Easy-to-Read, an important national level policy document, containing a summary of strategies and goals for e-government has also been analyzed based on the following questions: (3) How is the e-government constructed in the text? (4) How is the citizen constructed and positioned in the text? The collected material is analyzed using a discourse analysis inspired by Foucault.With the results from the interviews and the analyzis of the policy document, Easy-to-Read information has been discussed and examined as a technology to meet the needs of people with reading difficulties, putin an era of e-government.The findings of the study include the following: (1) The e-government is constructed as a service agency and the citizens are positioned as clients. Furthermore, the citizens are expected to participate digitally and be digitally competent. (2)Some of the representatives does not know, with certainty, to whom the texts are directed or if they are used.

Webbsystem för matprisjämförelser

This is a thesis project in the field of information technology which begins by evaluating existing food price comparison systems and subsequently aims to design an improved, web based system for said purpose. The system features interfaces for price reporting, price comparisons as well as various search and review functions. The objective is to create a system able to compete with existing price comparison systems, which requires careful selection of products that can be found in all foodstores that also represent different households; a user-friendly price reporting and price comparison interface and an efficient tool for ensuring the validity of reported prices.The designed system features a more accurate formula for calculating average prices in events where the real price is missing; a more reliable security mechanism forv alidation of reported prices and a more comprehensible interface for viewing price reports, reporting prices, reviewing stores and products in comparison with existing systems. The system does, however, suffer from some optimization issues primarily in the form of inefficient database modeling; SQL queries and JavaScript code although testing has shown that these shortcomings do not hamper overall performance to such a degree that usability is compromised. Further usability testing performed on the system with five test subjects shows that a high level of overall user-friendliness has been achieved even though some special features, such as the detailed report containing price information per product for each store need to be improved.It is not possible to say at this time whether or not the designed system will be able to compete with existing ones or if the very concept of food price comparisons per se is viable in terms of profitability and marketability.

Från hemtjänst till eHemtjänst

The number of elderly continues to increase in Sweden which puts pressure on the elderly care. Aproposed solution is to increase the use of information and communication technologies (ICT) inhome care to both streamline care and enable older people to manage on their own to a greaterextent. So far Västerås is the only municipality that has made a decision on an ICT solution, whichthey have chosen to call ?eHemtjänst? (eHomecare). The purpose of this paper was to investigatethe specific prerequisites and requirements for Gothenburg city regarding the potentialimplementation of eHemtjänst.

Informationskompetensen i användarundervisningen

This master thesis investigates the user education. Christine Bruce has presented a theory of information literacy in her research which has resulted in seven different aspects of information literacy. In this study I wanted to investigate what aspects there were and what they looked like in a practical educational situation. The methods used for this study were observation and a questionnaire. I analysed the observations by using Bruces aspects of information literacy to group the observed activities into the different aspects.

Augmented Reality i mobiltelefonen : En kunskapssammanställning med trafikinriktning

This master thesis is about Augmented Reality (AR), a phenomenon that has existed since the mid-fifties but only recently has become available for the general public. This report is a knowledge compilation about AR, focusing on AR in cell phones and the use of the technology in traffic related situations.AR is usually described as adding a digital layer of information onto the real world. There are different technologies to make virtual images; in cell phones sensor-based and camera-based technologies are the most common ones.In this report, the market of AR applications for cell phones has been investigated. Three use cases have also been investigated in order to get more knowledge about the designers' thoughts and visions.In order to analyze the technology and the applications in a broader and more scientific perspective, two theories has been used: Situation Awareness (SA) and the Service Dominant Logic (SDL). These theories seem useful when reflecting on the Swedish road administrations vision, and to investigate what the applications and the AR technology can contribute to the traffic domain.The conclusions of this thesis are that:- AR can be applied on most of the human senses, but augmenting by visualization is most common.- The market for cell phone applications is growing rapidly: AR applications are relatively new but on the rise.

Läkemedelssökning i vårddokumentationssystem : En användarcentrerad utveckling av läkemedelssökning i vårddokumentationssystem

This thesis examines the problems related to IT in the Swedish healthcare system, specifically the drug searching part of the electronic healthcare systems used in Sweden. The question formulation is divided into two questions: What parameters and functions are of greatest importance when performing a search on drugs, and how should these be presented in a graphical user interface? Thus the purpose is to answer these questions through developing a design concept, in the form of a prototype, which describes how a drug search can be carried out.The entry point is a central quality checked drug database that is managed and owned by Swedish county councils and regions. The problem is attacked through user-centered methods where interviews of physicians and developers, in conjunction with observations, are used to give an overview of the problem area as well as to specify a requirements specification for the prototype that this thesis aims to develop. The thesis result is a requirements specification in combination with a prototype that exemplifies how drug searching can be performed, the prototype is based the requirements gathered from the interviews with the user group of physicians..

Lärares syn på teknikämnet. : En enkätstudie av pedagogers tankar kring teknik på mellanstadiet

Syftet med denna studie är att få en inblick i hur lärare på mellanstadiet arbetar med teknikämnet i skolan. Detta görs genom en enkät, vars frågor är upplagda efter tre frågeställningar: Vilka tankar har lärarna om teknik? Hur ser pedagogernas teknikundervisning ut? Vilket undervisningsmaterial använder lärarna sig av i teknikämnet? Totalt är det 65 lärare som arbetar eller har arbetat med teknik på mellanstadiet som deltagit i studien. Enkäten har visat på att de flesta lärarna som deltagit tycker att teknikämnet är ett roligt, spännande och intressant ämne som dock är svår bedömt, tids- och materialkrävande. Undersökningen visar även att de flesta lärarna tycker det är bäst att arbeta med teori och praktik varvat, då båda delarna behövs för att eleverna skall förstå teknikens innebörd i samhället.

Kan probiotika förebygga atopiskt eksem hos högriskbarn?

Sahlgrenska Academy at University of Gothenburg Department of Internal Medicine and Clinical NutritionAbstractTitle: Can probiotics prevent atopic dermatitis in children with high risk?Author: Laura Pienihäkkinen and Max OlinSupervisor: Heléne Bertéus ForslundExaminer: Anna WinkvistProgramme: Dietician study programme, 180/240 ECTSType of paper: Examination paper, 15 hpDate: May 22, 2012Background Allergic disease is today common, this including atopic dermatitis, which is the most common inflammatory skin disease in the world. Heredity has been shown to play a major role in the development of this disease. It is therefore of high interest for both the individual and society to find effective methods for preventing atopic dermatitis in individuals with high risk profile. Probiotics are beneficial for the bacterial profile in the intestine and it is therefore of interest to study if they through their anti-inflammatory effect could prevent atopic dermatitis.Objective The aim was to study whether administration of probiotics to the mother and the child (directly or via breast milk) could prevent atopic dermatitis in children with high risk profile (at least one first degree relative with a diagnosed allergic disease).Search strategy A systematic literature search was done in databases PubMed and Scopus with search terms maternal, prenatal, probiotics, allergy, atopic dermatitis, prevention, and children.Selection criteria Randomized, controlled human studies and original articles in English were included.

Modelering av Wideband : Code Division Multiple Access

Today wireless transmission of data is becoming more and more popular and the need for faster transmission rates is increasing. Since the bandwidth is limited it is important to try to use it to the fullest. CDMA is a technology that allows multiple accesses on the same frequency and time thus making it very bandwidth efficient. The CDMA technology was first introduced in the second generation?s cellular systems but has since then been improved and is reused in today?s 3G systems as Wideband CDMA.
