Volvo Human Monitoring (VHM) is an ongoing project at Volvo Cars where they measure, amongst other parameters, inhalation and exhalation through a device called Respiratory Inductance Plethysmograph (RIP), on drivers. RIP measures changes in the cross-sectional area of the chest and abdomen. When the driver is in motion, such as when she is turning the vehicle, the cross-sectional area changes and noise in the RIP signal may arise.The noise results in a large number of manual adjustments in the analysis of the RIP signal, which is very time consuming and the validity of the device for measuring inhalation and exhalation is questioned.The purpose of this study was to improve the efficiency of the analysis of the RIP signal. The goal was to create a new data processing tool in Matlab that automatically detects inhalation and exhalation from a RIP signal with higher validity compared to the previous data processing tool.In this study, nine tests were performed on drivers while they were driving in different scenarios such as highway, country road and in city traffic. Inhalation and exhalation was measured using a RIP, a pneumotachograph with a tightly sealed facemask and a thermocouple placed between the nose and mouth, which was used as reference to the RIP.The result of this study was a data processing tool that automatically detects inhalation and exhalation with higher validity compared to the previous data processing tool.
Utskrivning från sjukhus ? En studie av utskrivningsprocessen vid en medicinklinik
Introduction: The interaction between different care facilities and professions is important in the care of older patients. Patients do not always get enough time to recover and often have a continued need for care. A discharge process of good structure in which the patient and relatives are participating and the continued need of care is assured is of importance in care of older patients.Objective: The overall purpose of this study is to compare the discharge process for patients over 75 years old admitted to a emergency medicine ward respective a emergency medicine ward with geriatric focus at a medicine clinic, to compare discharge process between these wards and evaluate the patients situation at home after discharge.Methods: A survey of medical records with a protocol and a telephone survey have been performed. Data was analyzed with descriptive and analytic statistic. Patients at the medical wards MAVA and care unit number 21/34, which are 75 years or older and are discharged to their own home, within the municipality of Göteborgs stad, in Sweden, are included in this study.Results: The discharge process differed between medicine wards with emergency medicine and geriatric focus.

Today's patients are turning increasingly tothe Internet before they visit their doctor, this is due to the electronic healthinformation is available 24 hours a day, 7 days a week while the regulardoctor usually have several weeks of waiting. Problems that can arise with theWeb-based information is that the patient does not have a medical educationto know whether the information is appropriate or not. Method: To explorethese questions, I decided to use both qualitative semi-structured postalquestionnaires and telephone interviews in which the physicians preferreddifferently.
Kvalitets och förbättringsarbete för ITtjänsteföretag
Wavecraft AB develops medical equipment for heating of organic synthesises. The heating is done with microwaves, which improves the process in both speed and accuracy compared to the more traditional methods where heating elements are used. This report discusses the developement of an automatic lid mechanism for one of Wavecraft's product prototypes. The company assumes that the final product will be integrated by customers into fully automated systems, and the upgrade from a manually to an automatically controlled lid is therefore an important step in the product's developement process.The first stage och the project was an idea generation process. The ideas generated here were organized into five different concepts of which the best one was selected through the use of a concept matrix.

"ADHD vanligt bland unga brottslingar" : En kritisk diskursanalys av hur Aftonbladet och Dagens Nyheter framställer ADHD
ADHD is the fastest growing diagnosis of the last decade and there is an ongoing debate about how ADHD should be understood with a psychosocial perspective opposed to a medical perspective. The purpose of this study was to investigate how a Swedish daily and evening newspaper (Aftonbladet and Dagens Nyheter) portrays ADHD. Further, the study asked whether medical or social explanation is used in the discourse that appears in newspaper articles, how ADHD is described as well as which people are quoted in the articles. In this study we used Norman Fairclough´s critical discourse analysis with the 26 sampled articles which we believe highlight different perspectives on ADHD diagnosis.Our study shows that there are representatives cited in the articles from school, the judiciary and the medical field. However representatives from social work are conspicuous by their absence.

Indirekt blodtrycksmätning på katt : påverkan av metod, miljö och ålder
The purpose of the present study was to study if the systemic blood pressure in cats
significant increases due to stress associated with a visit to a veterinarian clinic. We
also wanted to investigate the clinical utility of two different methods for indirect
blood pressure measurements in cats by assessing how easy they were to use and how
reliable measurements they provided. The methods that were used were oscillometric
(Memo Diagnostic) and ultrasound-doppler technique (Minidop). The blood pressure
was measured in both clinical environment and home environment. Fifty cats were
used in the study, from which measurements were impossible to obtain in one cat.

Hemsjukvårdscentralens arkiv : Ett ordnings- och förteckningsarbete
Hemsjukvårdscentralen began its work from Tunåsens Hospital in Uppsala in 1962, with the purpose to give conomic support to people who nursed their chronic sick relatives in home. Hemsjukvårdscentralen ended its work in 1987, and delivered its archive to the County council of Uppsala in 1988. About half of the archive consisted of medical records of the patients who had received economical support, and many of the archival records was considered as ?work papers?, non-archival records that could be discarded. Two obvious problems emerge from the organizing of the records.

Socionomen som chef inom va?rden : En kvalitativ studie av mo?tet mellan medicinsk och social kompetens
The purpose of this paper is to investigate how social workers, working in a management position in the health care system, perceive the encounter of the medical and social perspective. With seven qualitative interviews, the study tries to conclude whether or not social workers are accepted at managerial positions within the health care sector. The social worker is, as a manager in health care, a leader but at the same time in a professional alienation from the medical caregivers. Organizations in the health care sector are often multi professional and have their own long standing tradition, history and culture. The results show that the conditions for social workers, working in a management position in health care appear to be agreeable.
