Sjuksköterskors arbetsmiljö i telefonrådgivningen på vårdcentral. En pilotstudie.
Introduktion:I början av 2000-talet blev telefonrådgivning en starkt växande metod för patientkontakt dit människor kunde ringa för råd och stöd. Flera studier belyser olika faktorer i den kliniska arbetsmiljön eller omgivningen, som kan påverka sjuksköterskors beslut om vård, samt resultat av den vård som ges. I de flesta av de beskrivna arbetsmiljöerna möter sjuksköterskan den vårdsökande ansikte mot ansikte. Få studier belyser telefonsjuksköterskors arbetsmiljö i telefonrådgivningen på vårdcentral, samt hur arbetsmiljön påverkar sjuksköterskors kommunikation med den vårdsökande och besluten som tas. Syfte:Syftet med arbetet är att beskriva sjuksköterskors upplevelse av arbetsmiljön i telefonrådgivningen på vårdcentral.
New Business Model for District Heating Firms Stabilizing the National Energy System with a Future Variable Electricity Production
The aim of this thesis is to develop a new business model for district heating and cooling firms which can contribute to a stabilization of the Swedish national energy system. The business model is developed for a district heating and cooling firm and is exemplified with Fortum Heat. The theoretical investigation around the topic creates a rigid base for following qualitative empirical studies. Osterwalder?s canvas for business model generation is used together with a Casual Loop Diagram to identify a number of business opportunities which stabilizes the national energy system.
Snusets effekter på aeroba processer och energiomsättning under fysiskt arbete
Syftet med föreliggande studie var att undersöka effekterna av ett längre uppehåll från tobaks- och nikotinbruk på maximal aerob effekt och energiomsättning under submaximalt arbete hos regelbundet snusande personer. Metod23 snusare (18 män, 5 kvinnor) undersöktes före och efter >6 veckors uppehåll från snus (SSP). Försökspersonerna genomförde ett stegrande submaximalt arbete på cykelergometer, ett maximalt löptest och ett uthållighetsarbete bestående av 60 minuter cykling på 50 % av VO2max. Syreupptag (VO2), ventilation (VE), subjektivt skattad ansträngning på Borgs RPE-skala (RPE), hjärtfrekvens (HF) och blodtryck (BT) mättes. Blodprov togs för analys av kotinin, laktat [HLa], blodglukos och fria fettsyror (FFA) i vila och under arbete. ResultatSubmaximalt VO2 och energiomsättning påverkades inte av >6 veckors uppehåll från snus. VE, respiratorisk kvot (RQ), blodglukos och RPE var oförändrade under det stegrande submaximala arbetet.

Kan evidensbaserad design användas i upprustningen av miljonprogrammet?
Between 1965 and 1975 a major housing project was carried out in Sweden to resolve a major housing crisis, the so-called one million housing program (Swedish: miljonprogrammet). To raise the standards and create a more attractive housing in these areas is currently a very relevant topic in Sweden.Evidence-based design is the process of basing decisions of the built environment on credible research and studies to achieve the best possible outcome. This method is primarily used in the healthcare sector to improve quality of care and reduce costs by creating healthy environments.The possibility of refurbish apartment buildings from miljonprogrammet using evidence-based design has been studied by means of an extensive literature review and a closer examination of the residential area, Husby in Stockholm, which has been chosen to represent the miljonprogrammet in its entirety. Furthermore, the evidence-based research has been limited to seven fields; nature, noise, color, wayfinding, safe environment, daylight and thermal comfort which has been assessed to be applicable on housing. In order to obtain a comprehensive overview of the different fields, four different subjects were chosen to investigate further within each field; research and studies, laws and regulations, constructional aspect and Husby.
Grannskapstorg som fenomen - med fallstudien Axel Dahlströms torg
In the 1940s the Swedish town planning was inspired by the English city development with the concepts of neighbourhood and community planning. In order to promote democratic development and solidarity the ideal would be to create community centers with full service. Community centers are part of the building of the suburbs during the postwar period. The buildings in Sweden from 1940 - and -50s were built with the intentions to be good homes for all regardless of income, class and status. Collective solutions to individual problems were characteristic of the Swedish policy during this time.
Comparison of stable environment in prior approved and non-prior approved horse stables
To establish good horse welfare there are several factors that need to be considered. One important factor is the environment in which the horses are kept. In Sweden horses are stabled during long periods of time in the cold season and consequently the stable environment is even more important. The most essential environmental factors in a horse stable are ambient temperature, relative humidity (RH) and concentrations of contaminants in the stable air. The air in a horse stable contains dust, noxious gases, moulds and microorganisms which all can contribute to developing respiratory diseases in horses.
Tillvaratagande och återanvändning av träbyggnadsmaterial : tjänstedesign för återbruk inom byggsektorn
The purpose of this Bachelor degree project is to design different types of services that can increase the amount of re-used timber within the building sector and by that means improve their environmental efforts. By examining how the sectors environmental work concerning recycling and re-using timber as a building material is getting on at present, conclusions have been drawn about what further could be done for improvement.The project has shown that there is a scarcity of information and statistics within the sector, but that there are efforts in progress to change this. Questionnaires have been sent to a number of companies working with demolition and utilizing re-usable materials in order to find out what kind of problems there are within the trade. Unfortunately the survey gave insufficient result due to the low reply frequency.It is obvious that active environmental work within the building sector is important and the knowledge acquired while working with the project has led to the design of three suggestions for services regarded as being of interest for improving the negative environmental impact caused by the sector:Suggestion 1 ? Sale of construction parts prior to the demolition of a buildingSuggestion 2 ? Re-utilization circulation when manufacturing buildingsSuggestion 3 ? Education in relation to the purchase of houses The positive and negative qualities of the suggestions have been examined with SWOT-analysis and further adaptions and the results have been interpreted.
Planering av robotstall på Gästgivaregården Blacksta
This work has been done to develop a plan for a future dairy barn at theGästgivaregården and to show the space needed for cows and replacement heifers. Itwould also show the storage that will be needed. The design was largely based on resultsfrom studies on six different farms, but also the facts that are taken from research papersand articles in order to compare theory with practice. Because some farms only whereinterviewed by phone I have used a query form to obtain comparable resultes.The aim is to build a new barn with Automatic milking. I've drawn a milking stable for120 milking cow and replacement heifers with the capability to house up to 140 milkingcows if the farm would expand in the future.Calculations of feed amounts and space requirements have been made to see how manyhectares are needed to supply the cows and replacement heifers with feed and to knowabout what size of storage space is required.The investigations made in this writing are to answer questions about the AMS-unit`sposition and how to best maintain a good health status in the herd.
Klimatanpassning med grönstrukturplanering : Med exempel från Malmö stad
Climate change is expected to lead to increased rainfall and higher temperatures, among other things. This will have a major impact on our cities. Floods can lead to property damage as well as damages to human and animal health. Higher temperatures will increase the frequency of heat-related health risks and premature deaths. The consequences of climate change will be particularly large in our cities because of the city's morphology with a high amount of paved surfaces and buildings that affect the natural processes in areas such as drainage and absorption of solar radiation.
Estetik och funktion? En studie av tillkomstprocessen kring två svenska folkbiblioteksbyggnader.
The purpose of this essay is to study the coming into being of two newly built public libraries in Sweden, Malmö public library and Linköping public library. In both cases, the architect was appointed through a competition. We have examined the degree of importance that one has put on the buildings functionality and aesthetics, respectively. Furthermore we have studied how the cooperation between library staff and the architects has worked, and finally we have studied to which degree the parties involved think that the interests of the users has been taken into concern. The first main chapter of the report is an overview of the literature found on the subject where we present theories on library architecture used in Sweden as well as abroad.
Ventilationsbuller : Teknik och ekonomi för ett tyst system
Buller från ventilationssystem är ofta förekommande och påverkar oss mer eller mindre varje dag. Det finns krav på hur mycket det får låta ur ventilationssystemet som är uppsatta av Karlstads Kommun med utgångspunkt från Boverkets Byggregler, men hur ser möjligheterna ut för att kunna konstruera ett tystare ventilationssystem vid en skärpt kravnivå?Syftet är att utreda vilken kravnivå som är rimlig med hänsyn till teknik och ekonomi. Med utgångspunkt från Råtorps Förskola, som ägs och drivs av Karlstads Kommun, utförs beräkningar med hjälp av befintligt beräkningsmall samt ljudmätningar enligt Svensk Standard. Det görs för att ta reda på hur ljudmiljön i förskolan ser ut idag i relation till de krav som ställts.
Projektering av småhus med solvärme som huvudkälla
In this report a study has been done regarding different heating systems on which are the mostcomprehensive with solar heating systems. The report has also been focusing if solar power can beused as a primary heating source for supplying more than 50 % of the buildings total heatingproduction. The University of Dalarna constructed a demo-house for this purpose and according tocalculations the total solar usage is more than 50 %. This house has been made for referenceregarding the design of the heating system of property 5:37.Further studies have been made to compare different heating systems that are compatible with asolar system, where the compared systems purpose is to be independent of direct using electricity. Asystem of this design is regarded as sustainable according to environmental as economic issues.
Renovering av flerfamiljsbostäder inom miljonprogrammet ur ett energi- och lönsamhetsperspektiv
Miljonprogram is a Swedish building program from 1964 to 1975. During that time about a million homes were constructed. Now, almost 50 years later, they are in desperate need of renovation. In order to fulfil the Swedish environmental objective to decrease energy consumption 50 per cent until 2050, considerable housing stock built under the Miljonprogram has to be renovated.Focus in this thesis is on the building services and theirs profitability that can decrease energy consumption in households build during the Miljonprogram. Building construction is not considered in this report.
