Flertalet nutida medier innehåller datorgenererad tredimensionell grafik. Intresset och efterfrågan för denna typ av grafik, har gett upphov till utvecklandet av åtskilliga datorprogram. Programmen innehåller oftast en eller flera integrerade renderingsmotorer. Studien jämför renderingsmotorerna Mental Ray och V-Ray genom att diskutera deras skillnader i renderingstider, användarvänlighet och renderingskvalitet, vid simulering av realistiskt ljus. Det praktiska arbetet utfördes genom att rendera samma 3D-miljö med de två olika renderingsmotorerna.

I den olfaktoriska litteraturen finns olika åsikter om huruvida människor kan bibehålla en mental representation av en doft. I denna studie undersöktes hur bra vi är på att föreställa oss dofter jämfört med bilder av personer, med hypotesen att denna förmåga är sämre för dofter än för bilder. Deltagarna försökte namnge 40 personer (bilder) och 40 lukter, där den ena gruppen endast exponerades för stimuli i 4 sekunder (singelsamplingsgruppen), den andra fick obegränsad tillgång under hela namngivningsförsöket (multisamplingsgruppen). Grundantagandet är att om deltagarna kan föreställa sig ett objekt för sitt inre så är de inte så beroende av återexponering. Resultatet visade inte på någon signifikant interaktion mellan grupp och modalitet, men nominellt går resultatet i hypotesens riktning.

Previous studies have shown positive results on the use of music as postoperative pain relief. Quantitative studies have examined the effect of music on rated pain and otherparameters such as anxiety, relaxation and blood-pressure. The purpose of this study was to investigate the expectations and experiences of patients and nurses onimplementing music as postoperative pain relief in an orthopedic unitQualitative design and semi-structured interviews were used to examine expectations and experiences. Five patients and five nurses in the unit were interviewed.Four themes developed during the data-analysis. These themes were ?Expectations on music as postoperative pain relief?, ?Experiences of music as postoperative pain relief?,?Effects of music as postoperative pain relief? and ?Continued implementation of musicas postoperative pain relief?.

Syftet med denna examensuppsats var att undersöka och beskriva svenska stridspiloters upplevda mentala hälsa. En enkät utformades bestående av ett skattningsbatteri med frågor om sömn och trötthet, OSLO-3, CAGE, HADS, frågor om fysiska symptom, GHQ-12 och SRE. Enkäten skickades ut till 129 JAS 39 piloter i ordinarie tjänst vid flygdivisioner i Försvarsmakten och Förvarets Materielverk (FMV). Resultatet visade att 77% av piloterna i studien bedömdes ha symptom på mild depression och 46% hade symptom på mild ångest. De flesta av de deltagande piloterna hade inte några alkoholrelaterade problem och 83% uppgav att de hade lätta fysiska besvär.ANOVA-analysen visade att de deltagande piloterna på utbildningsförbandet i medeltal hade signifikant högre poäng på GHQ-12 än piloterna på insatsförbanden.

Introduction: The conversation is one of the main components of the nursing process in psychiatric care. The preunderstanding on this research field is described based on theoretical concepts that together form the basis for understanding the study; nurse's role in psychiatric care, communication and caring relationship, as well as theories of the caring conversation and person-centered care. Research on the caring conversation as a theory and how it is experienced by patients existed, however, no research from the nurse's perspective was found.Aim: The aim of the study was to describe nurses' experiences of the caring conversation with patients in psychiatric open care units.Method: Qualitative research interviews were conducted with six nurses working in outpatient psychiatric care in the west region in Sweden. The interviews were recorded, transcribed and then analyzed according to the qualitative content analysis as described by Graneheim and Lundman (2004).Results: Four categories with related subcategories were distinguished throughout the analysis: The caring conversation, The importance of the care plan, Limitations and Caring based on the patients narrative.Discussion: An uncertainty about what caring conversation is and what it should contain creates uncertainty in the nurse's work. This results in a need for training for the individual nurse and the further research to obtain evidence for the importance of conversation in caring work.

The aim of this study was to investigate nurse?s experience of working from the philosophy of palliative care in end of life at home. The study had a qualitative design. Semi-structured interviews were performed with nine nurses working in advanced palliative home care. The analysis of the material revealed four categories and two subcategories.

Syftet med föreliggande studie var att undersöka samband mellan de arbetsvillkor som berör gränslöst arbete och mental samt fysisk hälsa. Även att undersöka skillnader mellan olika anställningsförhållanden så som fastanställning och ej fastanställning och om de skiljer sig åt beroende på arbetsvillkor och hälsa. Deltagarna var 69 personer varav 42 stycken var kvinnor och 27 stycken var män. Resultaten visade att det fanns starka samband mellan de olika arbetsvillkoren och mental samt fysisk hälsa. Det visade sig även att det fanns ett flertal signifikanta skillnader mellan fastanställda och ej fastanställda.

The goal with this study have been to investigate how teachers in physical education perceive health as a concept, and how they choose to work with in the classes they teach. Health as a concept can be somewhat diffuse and as the Swedish curriculum doesn?t define the concept the teacher are given a freedom in interpreting what health is and how it will be taught to the students. This makes it interesting to study if teachers perceive health differently and if that affect what they are teaching their students.I used interviews as a method to answer my questions and the results show that there wasn?t much difference between the teachers in how they perceive health and how, and what, they teach their students.

Objective: The objective was to examine the incidence of constipation, and the preventive measures taken in relation with postoperative pain treatment with opioids at two orthopaedic surgery wards.Methods: The participants were patients that had undergone surgery in the back, hip or thigh. They were selected through systematic selection and a total of 46 electronic health records were examined. The factors investigated and tested for correlation with constipation were the usage of laxatives, daily fluid-intake and early mobilisation.Results: Totally, 26.1 % of the patients became constipated, and laxatives were prescribed to 65.2 % of the patients. Doctors prescribed 53.3 % of the laxatives, nurses 33.3 % and for the remaining 13.3 % it was uncertain who had written the prescription. Usage of laxatives seemed to cause constipation (p=0,025), whereas there was no correlation between constipation and early mobilization.

Background: Daily news reports of school violence, bullying and harassment are common. The school has developed into an arena which has been exposed into a growing unhealthyness. Paradoxically, financial resources decreases while demands on school staff increases. How does school staff and personal cope with these demands? Aim: We sought to study sense of coherence among school employees in two schools; a comparison between one health promotional school and one school in the process of working with health promotion.

ABSTRACTIntroduction: Postoperative wound infection is the third most common nosocomial infection in Sweden. The ever-growing problem of antibiotic resistance provides surgical departments a big challenge when it comes to preventing the spread of infection. Operating theatre nurses have a vital role in the prevention of infection. In addition, correct ventilation in the operating theatre is of great importance. The caregiver is responsible for quality assurance of ventilation in the operating theatre, but the work can be delegated to other staff within the department.

Urban farming can be viewed in several contexts. The first part of this work brings up the beneficial effects of farming on our physical and mental health, knowledge as well as on social life in cities. The introduction of gardening in schools can contribute to an increased awareness on both agricultural practices and importance as well as ecological processes. It can also be used in teaching of other subjects. Farming can also contribute to improving the household economy, and the economy on a municipal or national level.

The aim of this study was to examine differences in the experience of intrinsic work-motivation and to examine changes depending on profession, where the purchasers experienced a higher level of individual demands and control than the production leaders. Another purpose was to see how the intrinsic motivation needs predicted mental well-being in the professions. The study was carried out using an internet survey that was distributed by e-mail, there were 98 participants. Two questionnaires were used; Basic Need at Work scale (W-BNS) measured intrinsic motivation and GHQ12 measured mental well-being. The result showed that the staff overall had high intrinsic motivation with highest scores on relatedness followed by competence and lastly autonomy.

Introduction: Public health researchers have long been focusing on investigating health inpopulations through determinants such as income inequalities. Nevertheless, incomeinequalities can be considered an effect of the organization of welfare regimes. The publichealth status is largely affected by the organization of welfare regimes and consequently thereare large differences in health within and between welfare regimes. How are these differencesdistributed and how can they be explained?Aim: To compare health between welfare state regimes with the use of Esping-Andersen?swelfare regime typology and to investigate the relationship between welfare statedeterminants and health.Methods: A literary review based on 12 scientific articles.
