Effekten av icke-farmakologiska behandlingar i omvårdnaden av personer med demens och beteendemässiga och psykiska symtom : En litteraturstudie

Background: The prevalence of dementia increases both in Sweden and in the rest of the world. People with dementia often display some types of behavioral and psychological symptoms. These symptoms include, among other things, aggressiveness, inactivity, activity disturbance, anxiety, hallucinations and depression. The symptoms can create a negative impact of those with dementia, their caregivers and their next of kin. Aim: To describe the effect of non-pharmacological treatments have on the behavioral and psychological symptoms of people with dementia.

Tidssynkroniserade mätningar i vattenkraftstationer

Vattenfall and Svenska Kraftnät perform start-up tests, where hydropower generators are used to power up the electrical grid in case of a blackout. To monitor the electrical grid, Phasor Measurement Units (PMU) are used. Each PMU is individually equipped with a GPS-receiver to precisely timestamp the data relative to the official time UTC. During the test, it is also of interest to timestamp the measurement signals from individual hydropower generators to later compare with PMU-data, and thus study the power grids impact on the generator. The aim is to work out an appropriate method to make these measurements and to build a data acquisition system, capable of timestamp data relative to UTC, from a generator in one of Vattenfalls hydroelectric power stations. The problem is that the generator is located in an underground station which hampers the reception of GPS-signals and wiring should be avoided if possible. Time synchronization has been solved by using Vattenfalls network, which is synchronized by the network protocol NTP.

Undersökning av riskfaktorer med produktion och inmatning av data till en databas

Syftet med denna rapport är att undersöka vilka riskfaktorer det sociotekniska systemet bidrar med vid inmatning av producerade data till en specifik databas. Denna undersökning använder STAMP-metoden (Systems Theoretic Accidents Models and Processes) för att finna riskfaktorer i systemet. Metoden utgår från att samla data om systemet genom intervju, observation samt analys av annan dokumentation kring databasen för att sedan applicera STAMP-analys på dessa. Resultaten pekade på ett antal riskfaktorer vid inmatningen av producerade data, dessa kretsade primärt kring problem med existerande säkerhetsåtgärder, avsaknad av träning samt bristande kommunikation. Resultaten ledde till en slutsats om förbättringsåtgärder på dessa punkter.

Culhwch & Lúthien : Keltisk mytologi i J. R. R. Tolkiens sagovärld

This study investigates in what respects Celtic mythology influenced J. R. R. Tolkien when writing the sagas incorporated in the mythopoeic compilation of The Silmarillion. Through narrative and comparative analysis, stories from the Irish prose collection Lebor Gabála Érenn, as well as the Welsh medieval manuscript Mabinogion, are collated to the tales of The Silmarillion in order to illuminate possible influences.

EFFEKTIVISERING AV INTERN MATERIALHANTERING

Considering that the current technology is constantly improving, it becomes increasingly important to have an efficient logistics in a company to maintain profitability while achieving a competitive business. Efficient logistics may be accomplished by improving the internal materials handling. In this thesis the internal material handling of steel frames has been studied at a factory in Vaggeryd. The goal of this study is to investigate the problems that exist with the current production flow of products and provide suggestions on how it can be developed to reduce unnecessary handling and movement.The study has a deductive approach where the authors has been using literature studies parallel with empirical analyzes conducted at a company to achieve the purpose of the study. Documentation from the company and interviews with staff and observations form the basis for the Data collection carried out.

Sahlgrenska Academyat University of GothenburgDepartment of Internal Medicine and Clinical NutritionAbstractTitle: Breakfast and cognition from a youth perspectiveAuthor: Linn Kruse and Anneli HulldinSupervisor: Anna WinkvistExaminer: Frode SlindeProgramme: Dietician study programme, 180/240 ECTSType of paper: Examination paper, 15 hpDate: May 26, 2014Background: Breakfast as an influencing factor on cognition and is often on the table for discussion in society. A lot of research has been done about how omitting breakfast affects adolescents and their short time cognition. Cognition is complex as a concept and is measured in different ways and the existing research in the area often compares different types of breakfasts instead of the difference between eating and omitting breakfast.Objective: To evaluate the scientific evidence for an association between adolescents? breakfast eating and short time effects on cognition in adolescents.Search strategy: To find relevant articles a systematic literature search was made in the databases PubMed, Scopus and Cochrane. Search terms that were used were: children, young adults, adolescents, cognition, and breakfastSelection criteria: Ages 12-20 years, measures cognition, RCT, studies comparing breakfast eating with omitting breakfast, human studies, language English or Swedish, no sick adolescents or adolescents with diagnosis.Data collection and analysis: Two original articles met the inclusion criteria and were reviewed by the SBU audit template for RCT studies.

Radomoptimering för luftburna störsändarkapslar

These studies are done in behalf of Saab AB AVITRONICS in Järfälla in the form of a thesis atthe Royal Institute of Technology in Stockholm.The task was to examine the parameters that plays a role in the construction of modern radomesoperating in broadband applications.This was interesting for Saab to get an indication of which way they should go at the newdevelopment of radomes for the next generation of equipment for electronic warfare.After a thorough analysis of the influencing parameters, a optimization application was made toget a automated way to get a radome design by specifying data on the radome size, airloads,materials, etc.This is to minimise the time of the laborious work that radome development.inply.This was solved by letting ANSYS calculate the strength of the radome structure and MATLABcalculate electromagnetic data and cost models of different sizes and materials.All these parameters woven together with the optimization tool modeFrontier picks data from therespective program and perform an optimization algorithm and then iterate a step and sends thisdata to calculation programs for the new input data. In the end, we have received a convergedpoint with our optimal solution.For the presumptions and limitations for which applied for this thesis, the result was prettyintuitive. That is to say that the smaller radome - the less materal is needed and lowermanufacturing costs results in the cheapest solution possible. The reality is not so simple. Whereyou have to take more of the electrical details such as the effect on the transmitter as a majorfactor..

To derive quality from quantity

The purpose of this master thesis is to present a model that illuminates the important factors when deriving technical information from market data within a company. For companies to be able to become and stay competitive in the market, product quality is an important factor. Whilst good product quality leads to customer satisfaction and loyalty, lack of quality brings costs in service and replacements. To improve product quality, the developers need information and knowledge about what quality issues affect existing products. Most companies gather data from market about known issues, but in order eliminate known quality issues in new products; this data has to be transformed into information and knowledge.

KR?PTA : spår och ärrbildningar hos Johannes Heldén, Ingrid Storholmen och Anna Hallberg

Trough the analyses of three young contemporary Swedish and Norwegian poets, who all in one way or another work with the language as material, I will circulate around the term language materialism. Each poet has his or her specific distinctive feature wich makes them three completely different poets. But they are all challenging the borders of literature and even the grammatical laws of language. Apart from the analyses I sketch an historical line between the predecessors of the experiments with the poetic language in the past, starting with Mallarmé, and the experiments of today. My essay will in conclusion discuss the language poetry in a wider philosophical point of view, connected to Derrida and Wittgenstein.The first analysis introduces the author and artist Johannes Heldén through his debute poetry collection Burner.

Kan supplementering med omega-3 under graviditet påverka allergiprevalens hos barn?

Sahlgrenska Academyat University of GothenburgDepartment of Internal Medicin and Clinical NutritionAbstractTitle: Does supplementation of omega-3 during pregnancy affectprevalence of allergy in infants and children?Author: Peter Eliasson, Anna RahmSupervisor: Lena HulthénExaminer: Anna WinkvistProgramme: Dietician study programme, 180/240 ECTSType of paper: Examination paper, 15 ECTSDate: 2012-04-12BackgroundEpidemiologic research has shown an association between a high intake of fish and allergy.The underlying theory is that allergy develops already at a prenatal stage and food intakeduring pregnancy has been shown to be significant. Conducting research on allergy isproblematic since it has genetic, as well as enviromental, determinants.ObjectiveThis thesis attempts to conclude and evaluate research on a connection betweensupplementation of omega-3 during pregnancy and allergic outcomes in infants and children.Search strategyThe literature search was conducted in the databases PubMed and Scopus. Among thekeywords chosen were omega 3, supplement, pregnancy and allergy.Selection criteriaHuman RCT, that measured allergy, where the intervention consisted of supplementation withomega-3 for at least ten weeks during pregnancy and ceased at birth.Data collection and analysisThree articles were chosen for this thesis. The articles were examined using templates fromSBU and the quality of evidence was evaluated according to GRADE.Main resultsNone of the articles showed a protective effect on allergic outcome but in one of the studiesthere was significant reduction in eggallergy and another showed significant lower occurrenceof severe eczema.ConclusionsSupplementation with omega-3 during pregnancy does not occur to have an protective effecton allergic outcome in infants and childen but the evidence for this is considered to bemoderate.

Taluppfattningstest med enstaviga ord i brus: Normalvärden för barn i åldrarna 7, 10 och 13 år

Background: Phonemically balanced word lists are used when obtaining speech recognition scores in noise. These lists are designed for adults, but are still used for children. To properly obtain speech recognition scores in noise for children, normative data is needed to show what differences there are to be expected between children of different ages. Purpose: The main purpose is to obtain normative data for children in the ages of 7, 10 and 13 years for speech recognition scores in noise using words and to compare these with each other and with normative data of adults. A further purpose is to examine if there is any practice- or exhaustion effect to be seen when obtaining speech recognition scores in noise for children in the ages of 7, 10 and 13 years.Material: The participants were ten 7-year-olds, ten 10-year-olds and ten 13-year-olds.

Agile vs Hyper Agile : en studie av agilitet i metoder för datamodellering

Inom utvecklingen av de flesta typer av datorsystem används datormodeller för att strukturera lagringen och användningen av data. Likaså finns det flera olika datamodelleringsmetoder att välja bland för detta ändamål. I samarbete med ett företag har en fallstudie genomförts med syfte att undersöka hur agiliteten i två av dessa metoder påverkar utvecklingen av ett Data Warehouse (DW).  De två datamodelleringsmetoder som undersökts är Data Vaulting och Hyper Agility och arbetet har fokuserat på att undersöka skillnaderna mellan dessa när det gäller mängden ETL-kod som måste skrivas, funktionaliteten i datatransformationerna, möjligheten till att uppdatera systemstrukturen samt den totala kostnaden för utvecklingen av DW-lösningen. Inom ramen för fallstudien har en litteraturstudie genomförts och kombinerats med material från sex intervjuer, där respondenterna varit konsulter såväl som företagsrepresentanter.

Säg det! : En undersökning om hur rektor kan synliggöra lärares undervisningsförmågor likväl som läraren kan synliggöra elevens lärande ? en parallellprocess

-------------------------- 4AbstractThis study is a qualitative case study in order to delineate how visible learning processes in the classroom. The study draws its theory from researcher John Hattie's findings about effective teaching. Data collection is taken from a class in grade 2 in a medium-sized Swedish municipality. The result demonstrates how the communication takes place in the classroom based on the teacher's strategies and planning in relation to pupils' interests and their own initiative. Is there a mutual feedback between teachers and students while teaching? From five perspectives, and the definition of what visible learning is all about, the results shows many good examples of excellent teaching.

Avtryck i glas och kropp : om glasblåsning, teknik och representationer av kvinnokroppen

I am a glassblower and I am a woman. In this project I've been working with alternative representations of the female body, muscles and technology. Mouthblown objects contains traces of body and form representations.I've been using muscle sensors to collect data from my arms while I blow glass. A special has made 3D-models from the collected data and I've blown these viritual objects in glass.My work is based around issues like: What happens when I measure my muscles? Am I (and my process) affected by the data gathering? How can I create alternative representations of the female body? What is the relation between glassblowing, the objects, body and gender?.

Systematik eller subjetivitet? : En studie kring individuell lönesättning för lärare

The purpose of this study was to examine the routines of performance related pay systems in two Swedish municipal upper secondary schools. A second purpose was to examine what data was included for evaluation of a co-worker?s performance and how a principal collects data. The purpose was also to examine a principal and teachers´ view of performance related pay systems and if it was possible to note an agreement. Principals have been interviewed and teachers have answered a questionnaire to fulfil the purposes of this study.The study shows that the municipality had a good routine that included individual discussions with co-workers about their salary and had fixed municipal criteria.
