Nutritionsstatus och boendesituation hos patienter med kroniskt obstruktiv lungsjukdom : En empirisk studie
Kroniskt obstruktiv lungsjukdom (KOL) leder till ökat energibehov, relaterat till ökat andningsarbete och brister i näringsintag är vanligt hos patienter med KOL. Näringsmässigt stöd för patienter med KOL, som lider av nutritionsproblem, är en viktig del av omvårdnaden vid KOL.Syftet var att beskriva och jämföra nutritionsstatus, lungfunktion och boendesituation hos patienter med KOL inom primärvård.Studien har en beskrivande och komparativ design och genomfördes som en tvärsnittsstudie. Urval och datainsamling baserades på en tidigare studie och studiegruppen innehöll 81 deltagare. För att bedöma nutritionsstatus användes bedömningsinstrumentet Mini Nutritional Assessment (MNA).Resultatet visade att de inkluderade patienterna med KOL, som var ensamboende, bedömdes ha sämre nutritionsstatus än de icke ensamboende. Jämförelsen mellan lungfunktion och nutritionsstatus visade inget signifikant samband.

Variationen i användandet av IT-verktyget Trade : En fallstudie hos NCC
Companies that are facing the global market are put in to new challenges in order to streamline its business. One industry that has realized that changes are necessary is the construction industry, it is an industry witch is far behind the development of introducing information technology-tools systems in there business. It has shown there is a relation between high IT usage and high productivity, which is one of the reasons to why companies in the construction industry should purchase a business system especially for procurement. However, companies that have purchased a business system are facing difficulties in having their employees using it for its purpose. People react differently to changes and that?s why variations in quantities exist for usage of information technology-tools.
Störningsindikation på lågspänningsnät
Föreliggande rapport är avsedd som ett examensarbete i elektroteknik (20p).Syftet med arbetet är att skapa en applikation för att finna störningar pålågspänningsnätet upp till 95kHz. Bakgrunden till arbetet kommer frånenergibolagen som vill kunna skicka datainformation direkt pålågspänningsnätet, detta vill de kunna göra med hastigheter mellan 2k ? 5kHz. Beroende på med vilken hastighet man vill skicka information kan störningar mellan givna frekvenser hindra datatransmissionen, därför är detviktigt att hitta vid vilka frekvenser störningarna uppstår så att lämpligaåtgärder kan vidtas.Grundläggande delar i applikationen är ett oscilloskop för mätning, dator medGPIB- kort för upptagning av data och LabView programvara för hantering avdata. För frekvensanalys kommer Fast Fourier Transform, FFT, att användas,varvid en grundläggande beskrivning kommer att medfölja..
Nutritionspolicyn på en kirurgavdelning : En utvärdering av följsamheten till riktlinjerna
Introduction: Balance between the essential nutritive substances is important for aperson to maintain health. The surgical patient can be stricken with conditions, whichhave a negative impact on this balance and can lead to malnutrition. Working as a nurseit is important to identify patients that are malnourished or is in the risk zone ofmalnourishment since 30 % of all patients in hospitals are malnourished.Aim: The aim of this study was to examine the compliance to the guidelines fornutritional assessment and parenteral nutrition on a surgical ward. Also whether thenutritional treatment/-support was reported to the next caregivers if the patient wasmalnourished or was in the risk zone of malnourishment at the time of discharge.Method: 80 patients enrolled on the ward in the beginning of year 2011 were included.Audit of patient records was made according to the hospital guidelines for nutrition andparenteral nutrition and followed a study specific protocol.Results: The examination of the case records showed that the guidelines for nutritionwere partly complied with. Nutritional treatment/-support was reported to the nextcaregivers when needed.
The Effects of Technology-Based Self-Service on Grocery Retail : A Swedish Case
Technology based self-service (TBSS) used in supermarket self-scanning checkouts is a relatively new phenomenon in Sweden. Studies on TBSS as a self- checkout device have been formerly carried out but with focus on the customer perspective. The authors therefore saw a challenge in covering the self-scan checkout concept, from a company perspective. The purpose of this research paper is to investigate, through a management perspective, the changes brought about by implementing an innovative TBSS system in Swedish supermarkets, and its effect on the competitiveness of the company. This is done by presenting and linking the theoretical framework and empirical study in the research.

En studie av IT-miljön och dess användning inom förskolan
The purpose of this study is to examine the usage of IT technology within preschool and study how IT tools are used by preschool staff for administrative as well as pedagogical assignments. Several aspects affects the work preschool staff do with IT which concerns availability to technology, how technology is used and how technology is made available for the children. There are a number of questions linked to these aspects where some examples this study examines are which advantages, disadvantages, obstacles or other limitations that comes with introducing IT? This study also examines how, when and in what contexts IT is being used? Other questions examined are the pedagogue?s general views of IT, competence development and eventual needs of investment? Further on this study examines to some part how children interact with IT during pedagogical activities? The overall objective is to shed light on problems that preschool staff encounter in their daily work and on the basis of identifying important questions at issue that could constitute a basis for further research. The results of this study are based on both a literature review and a field study.
Musiklärares inställning till IKT i sin undervisning : en studie med komparativ ansats mellan Nya Zeeland och Sverige
The aim in this thesis is to study what attitude music teachers in Sweden and New Zealand have towards Information and Communication Technology (ICT) in music education and obtain a better understanding of how their attitudes affect the way they use ICT in their teaching. Another intention is to discuss differences and similarities between the teachers´ preferences regarding this issue in the two different countries, and whether it has any effect on teaching. It's a qualitative study based on interviews with music teachers from both countries. Through the answers we can get an impression about how ICT is used in music education, how the curriculum is interpreted when it comes to use ICT in music education and how the teachers' attitudes towards ICT affect the music education. This thesis shows that teachers are positive towards ICT in music education but the attitude, knowledge and the way of using it differs, due to access to technology and different opinions about what is essential in music and what is pedagogical.
Utvärdering av Sensus amningsutbildning för blivande föräldrar
ABSTRACTStatistics show that breastfeeding prevalence for Sweden has fallen since the mid 90´s. Studies show that breastfeeding offers health benefits to both mother and child and that the mothers' belief and confidence in their ability to breastfeed is a key factor to having a positive breastfeeding outcome. In 2010, Amningshjälpen in collaboration with Sensus studieförbund, started a nursing course, for mothers-to-be, who wished to breastfeed their babies and its aim was to prepare them for a successful and enjoyable experience.Objective: To examine whether a preparatory breastfeeding course can affect mothers' confidence in their ability to breastfeed and if that ability can affect the breastfeeding outcome when the child reaches four months. A further aim is to investigate the experience of perceived problems surrounding breastfeeding and what affect these might have on the mothers' confidence in breastfeeding when the child reaches four months.Design/Methods: A quantitative approach with prospective experimental design was used to evaluate the study. The questionnaire Breastfeeding Self-Efficacy Scale Short Form (BSES-SF) was used three times to measure women's trust in lactation.
Proportionalitetsprincipen : En studie av dess inverkan i LOU
The principle of proportionality is considered one of the most important contemporary legal principles on which it intends to protect individual citizens against disproportionate action by the authorities. This aroused our interest prior to this study. The essay reveals how such behavior might look like and how courts have chosen to adjudicate in cases where the individual has been discriminated against or subjected to unreasonable demands in public procurement. That section of the law that were current throughout all court cases are Public Procurement Act (2007:1097) LOU. That which we have seen in every court case is that the applicant has not received a proper fair chance when the requirements of the contract often been asked in a way that either exclude the smaller applicant company or rule out various potential applicants parties due to excessive and sometimes unnecessary requirements.
