Är det någon som ser min smärta? : En journalgranskningsstudie om smärtskattning och dokumentation av patienter med behov av smärtkonsultation

Weman, Emelie, Lindwall, Frida January 2016 (has links)
Bakgrund: Patienter med svår smärtproblematik utsätts för ett stort lidande och risken för psykiska- och fysiska komplikationer ökar. För att behandla dessa patienter på bästa sätt krävs adekvat smärtbehandling. För att kunna följa upp och utvärdera både smärtan och smärtbehandlingen är det viktigt med en god smärtdokumentation. Syfte: Att studera smärtdokumentationen hos tidigare inneliggande patienter med smärtproblematik som under denna tid blivit konsulterade av Smärtcentrum på Akademiska sjukhuset, samt jämföra dokumentationen mellan de avdelningar som studerats. Metod: Studiens forskningsdesign är en kvantitativ retrospektiv empirisk studie där journaler för patienter vars vård Smärtcentrum har varit delaktiga i under 2015 utgjorde datan för studien. Det var 30 ortopedjournaler och 28 onkologjournaler som granskades. Resultat: Resultatet visade att patienterna fick sin smärta dokumenterad två gånger eller färre under en period på tretton dagar. Smärtskattning dokumenterades mest frekvent. Något signifikant samband mellan längden på patienternas vårdtid och frekvens i smärtdokumentation kunde inte konstateras. Det fanns en skillnad i frekvensen av smärtdokumentationen mellan onkologavdelningarna och ortopedavdelningarna. Slutsats: Frekvensen av smärtdokumentationen på de granskade avdelningarna visade sig vara undermålig och följer därmed inte de riktlinjer som finns. Detta försvårar arbetet för både konsultverksamheten samt personal på berörda avdelningar att få en helhetsbild kring patienternas smärtproblematik.  Risken ökar för både komplikationer och lidande hos patienterna. Ytterligare forskning krävs för att undersöka vad anledningen till den bristande dokumentationen är. / Background: Patients with severe pain are subjected to great suffering and the risk of psychological- and physical complications increases. To treat these patients optimally it requires adequate pain management. In order to monitor and evaluate both the pain and the pain treatment it is important with pain documentation. Objective: To study the documentation of pain on previously hospitalized patients with pain problems who during that time were consulted by the Pain Centre at Akademiska hospital, as well as compare the documentation between the included wards. Method: The design is a quantitative retrospective empirical study of medical records of patients consulted by Pain Centre at Akademiska hospital during 2015. The final sample consisted of 30 records from the orthopedic clinic and 28 from oncology clinic. Results: The results showed that the hospitalized patients had their pain documented less than twice during a period of thirteen days. Pain Measurment was documented most frequently. No significant correlation between the length of care and frequency of pain documentation could be found. There was a difference in the frequency of pain documentation between the included wards. Conclusion: The frequency of pain documentation for the consulted patients in the included wards at Akademiska hospital proved to be deficient and does not follow the guidelines. This complicates the work of the health care staff, and the monitoring and evaluation of the treatment. This also increases the risk of complications and suffering of the patients. Further research is required to investigate the reason of the lack of documentation.

Žemės plutos judesių įvertinimo sudarant geodezinius tinklus tyrimas / Research of the earth crust movement evaluation creating geodetic networks

Kirklytė, Giedrė 05 June 2012 (has links)
Dabartiniai geodinaminiai procesai žemės paviršiuje pasireiškia vertikaliaisiais ir horiznotaliaisiais žemės plutos judesiais. Dėl vykstančių žemės plutos judesių keičiasi geodezinių ženklų padėtis, o dėl šios priežasties matavimų rezultatai bėgant laikui netenka reikalaujamo tikslumo. Darbo tikslas – ištirti vertikaliųjų žemės plutos judesių įtaką vertikaliesiems geodeziniams tinklams (Lietuvos vertikaliojo geodezinio tinklo pirmojo poligono pavyzdžiu). Tyrimo uždaviniai – atlikti literatūros šaltinių apžvalgą ir išnagrinėti dabartinių žemės plutos judesių vertinimo metodikas, atlikti vertikaliųjų žemės plutos judesių įtakos vertikaliajam geodeziniam tinklui tyrimą ekperimentiniame objekte, apibendrinti tyrimo rezultatus bei pateikti išvadas ir rekomendacijas. Tyrimo metodas – ekpserimentiniai ir analitiniai tyrimai. Iš atliktų tyrimų nustatyta, kad dėl vykstančių geodinaminių procesų apskaičiuotų pataisų reikšmė geodeziniams matavimams yra ne mažesnė už normalinių pataisų reikšmę. Įvertinant žemės plutos judesius, geodezinių ženklų aukščiai eksperimentiniame poligone kinta iki 18 mm, o geodinaminės pataisos yra nuo 3 iki 5 kartų didesnės už leistinas paklaidas. Daroma išvada, kad būtina įvertinti dabartinius žemės plutos judesius. / Recent geodynamic processes in the earth's surface appears by horizontal and vertical movements of the earth's crust. Because of these movements, geodetic marks change their position. Geodetic networks and geodetic measurements lose the required accuracy over the time. It is influenced by vertical movements of the earth's crust. Masters thesis aim - to investigate the vertical movements of the earth's crust affect for the vertical geodetic networks (the first polygon of Lithuanian geodetic vertical network). Masters thesis tasks – to make a literature review, examine the earth's crust movements evaluation methodologies, find out how vertical earth’s crust movement influence geodetic measurements, summarize the results and present conclusions and recommendations. Master thesis method – experimental and analytical investigation. Considering the earth's crust movements, the heights of the experimental character of geodesic polygon varies up to 18 mm, and the geodynamic corrections from 3 to 5 times are higher than the allowable correction. To sum up, the vertical earth’s crust movement impact must be evaluated. Structure: introduction, four chapters, conclusions and suggestions, six appendixes.

Turbiditet för indirekt mätning av metaller i vattendrag / Turbidity for indirect measurement of metals in watercourses

Jonsson, Jennifer January 2020 (has links)
When stormwater flows from hard surfaces in urban areas it contributes with pollutants to nearby watercourses. Also runoff from rural areas dominated by agriculture and forestry can contribute with nutrients and pollutants to watercourses. How maximum concentrations and annual loads of pollutants are transported yearly to lakes and seas is crucial information for an adequate management of our natural waters. Several metals, like lead, copper, cadmium and zinc are harmful to humans, animals and plants. Estimates of concentrations and transports of metals is today often based upon manually collected samples, flow proportional samples or modeling in programs calculated from standards. All of these methods contains a lot of uncertainties. The yearly transports in watercourses is calculated through linear interpolation between samples. Uncertainties in the calculated yearly transports tend to increase with lower sampling frequencies, since changes in metal concentration is often overlooked. This study is based on samples from Hågaån, a stream located in the proximity of Uppsala, Sweden. The stream has influences from both stormwater and runoff from agricultural lands. The purpose of the study was to investigate in what ways turbidity can be used as an indirect measurement of metals. The relationship between turbidity and different metals were analyzed through linear regression. The results shows that a high frequency measurements with a turbidity sensor can be used in several different ways depending on the strenght in the relationship between turbidity and metal. If the obtained relationship is strong, as is the case for lead, a turbidity sensor could be used as an indirect measurement in the watercourse. In those cases when the relationship does not have the same credibility, a turbidity sensor could instead be used to model the metal concentrations between samples. It might be possible to apply a relationship between turbidity and metals also for stormwater for some metals, but further studies are inquired. Since the quality and flow of stormwater are highly variant, high frequency measurements with a turbidity sensor could provide a more complete picture of how the concentrations of pollutants vary over time. The relationship between turbidity and metals is dependant of the metal content in particles, optical properties but also the concentration of dissolved metals, which vary between watercourses and over time. It is therefore necessary to measure turbidity and metal concentrations in the watercourse of interest under different hydrological conditions. The more complex the relatinship is, the more measurements are required. This limit the usage of sensors to monitor metals. / Dagvatten som rinner av från hårdgjorda ytor i bebyggda områden bidrar med föroreningar till närliggande vattendrag. Även naturlig avrinning från icke-hårdgjorda ytor, som odlingsmark och skogsmark, kan bidra med näringsämnen och föroreningar  till vattendrag. Hur höga halter som förekommer, samt vilka mängder av föroreningar som årligen transporteras ut i sjöar och hav är viktigt att veta för att kunna följa upp Sveriges miljömål Giftfri miljö och vattenförvaltningens krav på god status. Många metaller som exempelvis bly, koppar, kadmium och zink är skadliga för människor, djur och växter. Uppskattningar av totalhalter och metalltransporter görs idag ofta baserade på relativt glest uttagna stickprover, flödesproportionell provtagning eller modelleringar i dataprogram beräknade från schablonhalter.  Alla dessa metoder innehåller stora osäkerheter. Årstransporter i vattendrag beräknas genom linjär interpolering mellan uttagna stickprover. Osäkerheterna i de beräknade årstransporterna ökar vid lägre provtagningsfrekvens, eftersom det är lätt att förändringar i metallhalten förbises. Denna studie baseras på mätningar från Hågaån utanför Uppsala, ett vattendrag som är påverkat av  både dagvatten och avrinning från jordbruksmark. Syftet med studien var att undersöka på vilka sätt turbiditet kan användas för indirekt mätning av metaller. Samband mellan turbiditet och metaller undersöktes genom linjär regression. Resultatet från mätningarna i Hågaån visade att högfrekventa mätningar med en turbiditetssensor kan användas på flera sätt beroende på styrkan i sambandet mellan turbiditet och metall. Om sambandet som erhålls är starkt, vilket är fallet för bly, skulle en turbiditetssensor kunna användas som en indirekt mätning i vattendrag. I de fall då sambandet inte är lika starkt, kan en turbiditetssensor istället användas för att fylla i data mellan stickproverna vid transportberäkningar. Detta minskar behovet av tät provtagning vilket kan ge en kostnadsbesparing. Samband mellan turbiditet och metaller borde kunna upprättas och appliceras även på dagvatten för vissa metaller, men vidare studier med längre mätserier krävs. Eftersom dagvattnets kvalitet och flöde är så varierande skulle en turbiditetssensor kunna ge en bättre bild av hur föroreningshalterna varierar över tid för metaller som är bundna till partiklar. Det finns överlag stora utmaningar kopplade till att mäta i dagvatten och en sensor kan i vissa fall utgöra ett bra komplement till andra metoder. Sambandet mellan turbiditet och metallhalt beror av partiklarnas metallinnehåll, optiska egenskaper och även halten lösta metaller, vilket varierar mellan vattendrag och även över tid. Det är därför nödvändigt med mätningar av turbiditet och metallhalter i varje enskilt vattendrag och under olika hydrologiska förhållanden. Ju mer komplext sambandet är desto fler mätningar behövs. Det begränsar användningen av sensorer för att övervaka metaller.

Kvinnliga lärares psykosociala arbetsmiljö : En kvantitativ tvärsnittsstudie om den självupplevda psykosociala arbetsmiljön, ur ett salutogent perspektiv / Female teachers psychosocial work environment : A quantitative cross-sectional study about the self-reported psychosocial work environment in a salutogenic perspective

Pettersson, Julia, Adolfsson, Ida January 2019 (has links)
Kvinnliga lärare upplever sitt arbete som meningsfullt samtidigt som de utsätts för tidspress, vilket har en negativ inverkan på deras psykosociala arbetsmiljö och hälsa. Syftet med denna studie var att beskriva den självupplevda psykosociala arbetsmiljön hos kvinnliga lärare ur ett salutogent perspektiv. En tvärsnittsstudie enligt en kvantitativ design gjordes på 43 kvinnliga lärare på tre olika skolor med hjälp av instrumentet Work Experience Measurment Scale (WEMS). Kompletterande frågor om ålder och år av yrkeserfarenhet tillfördes för att undersöka eventuellt samband. Resultatet visade att det inte finns något statistiskt signifikant samband mellan ålder eller år av yrkeserfarenhet i hur deltagarna upplever sin psykosociala arbetsmiljö. För att beskriva kvinnliga lärares psykosociala arbetsmiljö ur ett salutogent perspektiv användes främst modellen “känsla av sammanhang” (KASAM). Deltagarna har starkt KASAM vad det gäller meningsfullhet men svagare KASAM i hanterbarhet och begriplighet. Slutsatsen för studien visar på att kvinnliga lärare upplever sitt arbete som meningsfullt vilket påverkar den psykosociala arbetsmiljön positivt. Samtidigt utsätts de för tidspress, vilket har en negativ inverkan på deras psykosociala arbetsmiljö. / Female teachers experiencing their work meaningful at the same time the work expose them for time pressure, which can have a negative impact on the health. The aim of this study was to describe self-perceived psychosocial work environment for female teachers in a salutogenic approach. A cross-sectional study with a quantitative design with 43 female teachers on three different schools was preformed, using the instrument Work Experience Measurement Scale (WEMS). Additional questions about age and years of work experience added to explore any relationship. The result show that there was no statistic significant relationship between age or years of work experience in how the participants experiencing their psychosocial work environment. To describe female teachers psychosocial work environment in a salutogenic approach has uppermost the model “Sense of coherence” (SOC) been used. The participants have a strong SOC regarding meaningfulness, but weaker SOC regarding manageability and comprehensibility. The conclusion of this study show that female teachers experience their work meaningful, which affect the psychosocial work environment positive, at the same time they are exposed for time pressure, which affect the psychosocial work environment negative.

Development and Verification of Control and Protection Strategies in Hybrid AC/DC Power Systems for Smart Grid Applications

Salehi Pour Mehr, Vahid 02 November 2012 (has links)
Modern power networks incorporate communications and information technology infrastructure into the electrical power system to create a smart grid in terms of control and operation. The smart grid enables real-time communication and control between consumers and utility companies allowing suppliers to optimize energy usage based on price preference and system technical issues. The smart grid design aims to provide overall power system monitoring, create protection and control strategies to maintain system performance, stability and security. This dissertation contributed to the development of a unique and novel smart grid test-bed laboratory with integrated monitoring, protection and control systems. This test-bed was used as a platform to test the smart grid operational ideas developed here. The implementation of this system in the real-time software creates an environment for studying, implementing and verifying novel control and protection schemes developed in this dissertation. Phasor measurement techniques were developed using the available Data Acquisition (DAQ) devices in order to monitor all points in the power system in real time. This provides a practical view of system parameter changes, system abnormal conditions and its stability and security information system. These developments provide valuable measurements for technical power system operators in the energy control centers. Phasor Measurement technology is an excellent solution for improving system planning, operation and energy trading in addition to enabling advanced applications in Wide Area Monitoring, Protection and Control (WAMPAC). Moreover, a virtual protection system was developed and implemented in the smart grid laboratory with integrated functionality for wide area applications. Experiments and procedures were developed in the system in order to detect the system abnormal conditions and apply proper remedies to heal the system. A design for DC microgrid was developed to integrate it to the AC system with appropriate control capability. This system represents realistic hybrid AC/DC microgrids connectivity to the AC side to study the use of such architecture in system operation to help remedy system abnormal conditions. In addition, this dissertation explored the challenges and feasibility of the implementation of real-time system analysis features in order to monitor the system security and stability measures. These indices are measured experimentally during the operation of the developed hybrid AC/DC microgrids. Furthermore, a real-time optimal power flow system was implemented to optimally manage the power sharing between AC generators and DC side resources. A study relating to real-time energy management algorithm in hybrid microgrids was performed to evaluate the effects of using energy storage resources and their use in mitigating heavy load impacts on system stability and operational security.
