Fysisk aktivitet i ett livslångt perspektiv : En studie om lärares, i ämnet idrott och hälsa,syn på fysisk aktivitet i ett livslångt perspektiv
AimThe aim of this study has been to examine how health enhancement teachers in Montana, USA, view the value of physical activity from a lifelong perspective.In what way does the health enhancement teacher think the importance of physical activity from a lifelong perspective could be presented?What resources are available for teachers to present the value of physical activity from a lifelong perspective?MethodThe issue has been answered through qualitative interviews consisting of six health enhancement teachers, four women and two men, in Montana, USA. One of the teachers worked at an elementary school (for 30 years), three teachers worked at middle schools (20, 10 and 8 years of work experience) and two of the teachers interviewed worked at a high school (30 and 3 years). ResultsThe majority of teachers feel that a wide variety of activities, adapted to an individual level, and the understanding of a healthy lifestyle are important in order for the teacher to present the value of physical activity from a lifelong perspective.The teachers felt they had sufficient material in order to present the value of physical activity, where the school budget provided the teachers with materials every year. In addition to the budget, all the teachers had 12 hours of professional development every year where they could attend conferences or their own choice of professional development.ConclusionWith the help in forms of professional development offered by the school, conferences, meeting with other teachers, and their own choice of development, the teachers instruction techniques could increase which could help the teachers to find the pupils? interest for different kinds of physical activities.KeywordsPhysical education and health, physical activity, SOC, sense of coherence..
Mikroskopering av opaka faser - en studie från Skyttgruvan, Falun.
In nature there are about 4,500 minerals identified. These can roughly be divided into two groups, opaque phases and non-opaque phases, with the exception that some opaque phases also may act as a non-opaque phase in different circumstances. The division is made on the basis of the optical properties. Opaque phases are nontransparent, which means that a different type of microscope must be used. A conventional microscope uses transmitted light while the microscope for opaque phases or the ore microscope uses reflected light.
Validering av Inertial Measurment Units som insamlare av data för drivande av OpenSim-modell
The purpose of this paper is to investigate the possibility of replacing data from highspeed filming (Qualisys motion capture) with data from Inertial Measurement Units (X-io technologies), when used to run a model of torso and pelvis in OpenSim. Qualisys motion capture data is used as the golden standard to validate the result visually and with Bland-Altman plots.In order to obtain comparable data experiments are conducted where both methods of collecting data are used simultaneously. Data from the IMU's then need to be processed in Matlab before it can be used to run the OpenSim modell. Several Matlab programs rotate the IMU data to a static reference frame, filter and integrate it, then create viritual markers that correspond to Qualisys' optical markers.The conclusion is that using IMU as a method for collecting data can replace Qualisys in some applications, but not in ones that require high precision. However, this paper only begins the examination of IMU's and there are most likely improvements to be made..
Förbränningslära för bubblandefluidbädd
Radio Frequency Identification, RFID, is a convenient way to enable contactless identification which does not require any physical nor optical contact. As with any radio-based communication the signal can be intercepted, thus making the technology vulnerable to several kinds of attacks. Interception of communication is not the only threat. Since RFID tags might contain personal information or information that will grant the owner access to secure areas, skimming and spoofing attacks are also major threats against this technology. In this thesis report, the perspective of an adversary is portrayed in an RFID-enabled environment by presenting where RFID is used and how it could be abused.

Effekter av AktiVERA-projektet på långtidssjukskrivna arbetstagare i Bjuvs Kommun
Syfte:Att se om en positiv effekt av ett interventionsprojekt i gruppen långtidssjukskrivna kan påvisas utöver den intuitiva nytta som förutsågs.Undersökt grupp och metod:7 långtidssjukskrivna kvinnor inom vård och omsorg med anställning i Bjuvs Kommun erbjuds ett aktiveringsprojekt kallat AktiVERA. Detta innebar gruppmöten med representation av arbetsgivaren, företagshälsovården och det lokala Försäkringskassekontoret samt friskvårdsinsatser och förväntan om att ta aktiv del i rehabiliteringsprocessen.De 7 fallen matchades med 7 kontroller och de sammanlagt 14 individerna fick i två omgångar besvara enkäterna Subjective Health Complaints (SHC) och Sense of Coherence (SOC) med knappt 6 månaders intervall.Resultat/diskussion:Resultatet av projektet blev inte helt oväntat väsentligen oförändrad grad av arbetsförmåga och utfall i de båda enkäterna Subjective Health Complaints (SHC) och Sense of Coherence (SOC). Någon statistiskt signifikant förändring av enkätufallen som resultat av interventionen kunde inte ses med den använda metoden parad T-test.Detta kan förklaras av att den undersökta gruppen var liten och att observationstiden på knappa 6 månader för förhållanden med lång förändringslatens. Emellertid kan man fortsatt hävda intuitiv nytta av den här typen av intervention hos långtidssjukskrivna. Sammantaget framkom också bekräftande uppgifter om nedsatta salutogena faktorer och vulnerabilitet i gruppen övre medelålders kvinnor med anställning inom vård och omsorg.Slutsats:Någon positiv effekt kunde inte säkert påvisas men intuitiv nytta har säkert förelegat och interventionen som sådan är lovvärd i en grupp där lidandet är stort parallellt med stora samhällsekonomiska konsekvenser.Referens:1.
Röntgenbilder: en studie av bildkvalitet inom medicinsk
röntgendiagnostik: en matematisk metod för jämförelse
mellan olika röntgenapparater
I sjukvården världen över tas dagligen tusentals röntgenbilder. Användningsområdena är många, men i de flesta fall är syftet att i något avseende avgöra patientens hälsa. Bilderna utvärderas av läkare för att patienten ska få rätt diagnos. För att läkaren ska kunna göra en korrekt bedömning av bilden och därmed ge patienten den behandling som situationen kräver måste bilden vara rättvisande och vara av sådan kvalitet att alla viktiga detaljer går att urskilja. Bildkvalitet är ett ganska diffust begrepp och ofta används subjektiva bedömningsmetoder för att bestämma ifall en bild är bra eller dålig.
Narrare humanum est (Att berätta är mänskligt) : En kvalitativ intervjustudie om berättande som undervisningsstrategi i historia
The purpose of this essay has been to do a study on narration as a strategy in history education. By taking a starting point in the perspective that Shulman calls ?wisdom of practice? and other studies I interviewed three teachers that were all experts in narration. This to have an insight in how they looked at the oral narration and on its role in history education. Is there a common view among the interviewed techers and to what extent are the traits and qualities of story telling described in litterature linked to the teachers? answers?My results show that the oral narration is not a straight and exclusive teaching strategy; it differs from teacher to teacher.
Faktorer för att upprätthålla psykosocial hälsa : -en studie utifrån socialsekreterares egna upplevelser
Research on psychosocial health in social work isn't developed enough. Instead, there's much more research on psychosocial unhealth. What about social workers, the unhealth is often related to the situation at work and the work environment.The aim of this study was to "during interviews understand the factors which social workers experience as important to maintain their own psychosocial health in the life situations". With hermeneutic method the particular interest was directed on how the participants experienced and explained their psychosocial health on the basis of their life situations, and the results was analyzed with Antonovsky's (1991/2005) perspective directed on health and Sense of Coherence (SOC). In the study, we used a qualitative form of interviews which allowed our participants to answer with their own words and from how they interpreted the questions.
Signal- och bildbehandling på moderna grafikprocessorer
En modern grafikprocessor är oerhört kraftfull och har en prestanda som potentiellt sett är många gånger högre än för en modern mikroprocessor. I takt med att grafikprocessorn blivit alltmer programmerbar har det blivit möjligt att använda den för beräkningstunga tillämpningar utanför dess normala användningsområde. Inom det här arbetet utreds vilka möjligheter och begränsningar som uppstår vid användandet av grafikprocessorer för generell programmering. Arbetet inriktas främst mot signal- och bildbehandlingstillämpningar men mycket av principerna är tillämpliga även inom andra områden.Ett ramverk för bildbehandling implementeras och några algoritmer inom bildanalys realiseras och utvärderas, bland annat stereoseende och beräkning av optiskt flöde. Resultaten visar på att vissa tillämpningar kan uppvisa en avsevärd prestandaökning i en grafikprocessor jämfört med i en mikroprocessor men att andra tillämpningar kan vara ineffektiva eller mycket svåra att implementera..
Att få göra sin röst hörd : Elevers upplevelser av elevinflytandets betydelse för deras motivation i skolarbetet
AbstraktHaving influence over questions that concern us is a part of the society that we live in, where every individual have the right to make her voice heard (Danell, 2006). For many decades, the school has had many different ways to give the students influence. Rönnlund (2013) is giving a historical overview of the history of students influence and enlighten us how the influence has changed over time. The influence from the students is very important and it is the students right to make their voices heard about things that concerns their work environment but also to affect their curriculum. The education in school should be fitted to every individual student (Danell, 2006). According to Aaron Antonovsky (2007) our wellbeing is based on that we all can take part and deicide about the things we are meant to do.
Som att flyga utan fallskärm. En systematisk litteraturstudie av faktorer som kan gynna respektive hindra den nyutbildade sjuksköterskans utveckling
The aim of this study was to illuminate critical factors that facilitate respectively obstruct the novice nurse's development during her first year in the profession. The method used was a systematic literature review according to Goodman's model. The 8 qualitative scientific articles were scrutinized by using a form developed by Pedersen and Sigling (2002). The result shows that cognitive factors, stress, social factors as well as affective factors are critical during the novice nurse's first professional year. The results are related to Antonovsky's concept sense of coherence..
Analys av haptoglobin i bovint serum med surface plasmon resonance biosensorteknik :
The concentration of acute phase proteins in serum is altered as a response to inflammation, infection or trauma. this makes these proteins potential biomarkers of unspecific pathological processes. In cattle, haptoglobin and serum amyloid A are the two acute phase proteins that show the largest increase in serum concentration as a result of inflammatory processes. The haptoglobin concentration has been shown to correlate to clinical signs as well as inflammatory processes found at post mortem examination. This feature could be useful prognosis of the individual as well as for monitoring the health status of a herd or identifying carcasses that shold be examined closer at the slaughter-house.
