Översättning och validering av Voice-Related Quality of Life / Translation and validation of Voice-Related Quality of Life

Gustafsson, Erik, Larsson, Fredrik January 2012 (has links)
En röststörning kan sägas föreligga då rösten inte fungerar eller låter som den brukar så att det påverkar kommunikationen. Prevalensen för röststörningar uppskattas till omkring 6 % av den vuxna befolkningen. När rösten inte fungerar som den ska leder det till emotionella, sociala och funktionella svårigheter för individen och har negativ inverkan på livskvaliteten. Voice- Related Quality of Life (V-RQOL) är ett självskattningsformulär som mäter vilken inverkan en röststörning kan ha på individens livskvalitet. Detta instrument är internationellt välanvänt, men har inte funnits översatt till svenska. Syftet med föreliggande uppsats var att översätta och validera V-RQOL för en svensk population. Översättningen skedde genom så kallad back translation och den svenska versionen fick namnet Röstrelaterad livskvalitet (RRL). RRL och Rösthandikappindex (RHI) distribuerades i pappersformat till en röstpatientgrupp (n = 88) och en röstfrisk grupp (n = 110). Reliabiliteten av domänerna och samtliga tio påståenden på RRL var hög för patientgruppen med Cronbach’s alfa- värden från 0.82 till 0.90. Det fanns en tydlig relation mellan den självskattade röstkvaliteten och poängen på RRL och formuläret kunde även differentiera mellan röstpatienter och röstfriska. Dessa resultat indikerar att formulärets begreppsvaliditet är god. Pearson’s korrelationsanalys visade att det fanns en signifikant negativ korrelation mellan RRL:s och RHI:s domäner och totalpoäng. Detta starka samband mellan ”the gold standard”, RHI, och RRL innebär en god kriterierelaterad validitet för formuläret. Sammanfattningsvis visar resultaten att RRL har hög reliabilitet och god validitet, dessutom är formuläret kort vilket innebär en liten arbetsinsats. Formuläret anses därför vara ett pålitligt och värdefullt tillägg i den kliniska bedömningen av röststörningar. / A voice disorder can be said to exist when the voice does not work or sound as it normally should in a manner so that it interferes with communication. The prevalence of voice disorders is estimated to be about 6 % of the adult population. When the voice does not work as it should it may lead to emotional, social and functional difficulties for the individual and with negative effects on the quality of life. Voice- Related Quality of Life (V-RQOL) is a self-reporting questionnaire which measures the effect of a voice disorder on the quality of life of an individual. The instrument is frequently used internationally, but no Swedish translation has existed. In the present study, the purpose was to translate and validate V-RQOL for a Swedish population. The method for translating the questionnaire was back translation. The translated questionnaire was given the Swedish name Röstrelaterad livskvalitet (RRL). RRL and the Swedish version of The Voice Handicap Index, Rösthandikappindex (RHI), was distributed to a group of voice patients (n = 88) and a group of non-voice patients (n = 110). The reliability of the domains and the combined items of RRL was high according to Cronbach’s alpha with alpha values ranging from 0.82 to 0.90. There was a strong relation between the self–estimated voice quality and the scores on RRL, and the RRL- questionnaire was shown to differentiate between voice patients and non-voice patients. These results indicate that the construct validity of the questionnaire is good. Pearson’s correlation analysis demonstrated a significant negative correlation between the domains and total scores of RRL and RHI. This strong relation between “the gold standard”, RHI, and RRL proved that the criterion validity of the questionnaire is good. In summary the results show that RRL has a high reliability and good validity, in addition to this, the questionnaire is short and requires minimal work. The questionnaire is therefore considered to be a reliable and valuable addition to the clinical assessment of voice disorders.

Transfer pricing : the compliance of the distribution functions of RHI Refractories Africa with SARS legislation

Fourie, Albert Roeloff 12 1900 (has links)
Thesis (MBA)--Stellenbosch University, 2006. / ENGLISH ABSTRACT: Governments do not want their tax collection to be affected by multinational companies that make use of distorted pricing models in order to maximize profits. For this reason Governments everywhere are implementing strict transfer pricing policies. These policies are mainly based on the OECD Guidelines with respect to transfer pricing. On the other hand, multinational companies do not want to be exposed to double taxation. The South African government also introduced regulations with respect to transfer prices set by multinational companies. Section 31 of the Income Tax Act 58, 1962, deals specifically with the issue of transfer pricing. This is fully explained in Practice Note 7 of SARS. RHI Refractories Africa, as part of the multinational company RHI-Ag, has to comply with SARS legislation. RHI Refractories Africa purchase many materials and products from the parent company for resale in the local market. The SEN is one such product and was selected for evaluation. This study found, after evaluation of the functions performed by RHI Refractories Africa and evaluating all the various preferred methods, the Resale Price Method (RPM) to be the most appropriate method to be used in the evaluation of the status of RHI Refractories Africa with respect to compliance with current SARS legislation. The gross margins eamed by RHI Refractories Africa on the sale of TYK and THOR SENs were compared. It was found that the gross margins earned on the sale of THOR SENs in the controlled transaction were actually higher than those earned in the uncontrolled transaction with TYK. The conclusion of this study is that RHI Refractories Africa does comply with current SARS legislation as measured against the guidelines of Practice Note 7 from SARS. This study further proposes that RHI Refractories Africa evaluate and document the process followed for all the inter-company transactions in order to ensure full compliance with SARS legislation. / AFRIKAANSE OPSOMMING: Regerings wil verhoed dat die belasting basis verklein word deur multinasionale maatskappye wat gebruik maak van prys modelIe wat daarop gemik is om belasting te ontduik en sodoende die marges van die maaskappye te verhoog. Vir die rede implimenteer regerings strenger maatreels om te verseker dat oordrag pryse markverwant is en bly. Die riglyne soos voorgestel deur die OECD word meestal as basis gebruik vir die opstel van lokale wetgewing. Terselfdertyd wil multinasionale maatskapye ook nie dubbele belasting betaal nie. Die Suid Afrikaanse regering het wetgewing daar gestel as deeI van Seksie 31 van die Inkomste Belasting Wet 58, 1962, wat spesifiek handel met oordrag pryse. Die wetgewing word verder verduidelik in Praktiese Nota 7. RHI Refractories Africa, as deeI van die multinasionale maatskapy RHI-Ag, moet voldoen aan SARS wetgewing. RHI Refractories Africa koop 'n verskeidenheid van materiale en produkte van die moeder-maatskapy vir herverkoop in die lokale mark. Die SEN is een so 'n produk en is gekies vir evaluasie. Die funksies wat RHI Refractories Afrika uitvoer ten opsigte van die verkoop van SENs is ten volle ondersoek. Die verskillende metodes vir evaluering van die oordrag prys soos voorgestel deur SARS is ook ondersoek en daar is gevind dat die Herverkoop Prys Model (RPM) die mees geskikte model is vir RHI Refractories Africa om te gebruik in die evaluering van die verkoop van SENs. Die bruto marge wat RHI Refractories Africa behaal met die verkoop van TYK en THOR SENs is vergelyk. Daar is gevind dat die bruto marge wat behaal is met THOR SENs, as deel van die beheerde transaksie, in werklikheid groter is as die wat met TYK SENs in die onbeheerde transaksie behaal is. Die konklusie van die studie is dat RHI Refractories Africa wel voldoen aan die vereistes daar gestel deur SARS soos gemeet aan die riglyne van Praktiese Nota 7. Die studie stel voor dat RHI Refractories Africa al die intermaatskaplike transaksies evalueer aan die hand van die SARS riglyne om te verseker dat daar ten volle voldoen word aan die vereistes van SARS.

Vyhledávání a hodnocení závažnosti endoteliální dysfunkce u dětí s chronickým autoimunitním onemocněním / Searching for and Evaluating the Severity of Endothelial Dysfunction in Children with Chronic Autoimmune Disease

Sýkorová, Aneta January 2019 (has links)
We aimed to evaluate the endothelial function by combining RHI measurements and specific biochemical markers in the children with possible risk of premature manifestation of atherosclerosis and in the control group of healthy children. In all, 124 children (of which 106 patients divided into five groups according to diagnosis - type 1 diabetes mellitus, Crohn's disease, cystic fibrosis, familial hypercholesterolemia and acute lymphoblastic leukemia and 18 healthy controls) were enrolled in the study. During the study, we measured RHI using a new plethysmographic method and further evaluated biochemical markers of endothelial dysfunction (ADMA, E-selectin, hsCRP and VCAM) and lipidogram in individual groups of children. The primary objective of our study was the determination of RHI and biochemical parameters in healthy subjects and in selected risk groups of children (type 1 diabetes mellitus, Crohn's disease, cystic fibrosis, familial hypercholesterolemia and children after successful treatment of acute lymphoblastic leukemia). At the same time, we compared patients from individual groups with the control group. We found significantly elevated RHI values in groups of children with type 1 diabetes, Crohn's disease, cystic fibrosis, and children after successful treatment of acute lymphoblastic leukemia....

Augmenting communication channels toward the evolution of autonomous construction sites

Winqvist, David January 2016 (has links)
Context In the last centuries, we have been generating and building infrastructure at a faster pace than ever before. Simultaneously the costs for labor and construction sectors as road and house building is increasing. This provides room for autonomous machines. The development of infrastructure is accomplished through highly efficient and productive construction machinery that progressively modernizes to form the society. In order to increase the pace of development, both cars and industry are getting more and more automated. Volvo Construction Equipment is exploring the autonomous vehicle space. The new machines complement and perfect the human work with efficiency, reliability, and durability. There is however, a question of trust between the human workers and the autonomous machines, I will in this thesis investigate methods on how to develop trust through communication systems with autonomous machines.   Objectives To create recommendations and solutions for products that build trust between human and automated machines on a construction site.   Method Outcome is reached through a case study exploration with validated learning, meaning that it will incorporate learnings through prototype iterations.   Results The result evaluates how trust could be developed between humans and autonomous machinery at a construction site and how communication methods between these parties could be implemented while maintaining high levels of efficiency and safety.   Conclusion Findings in this thesis indicates that trust is developed over time with reliable systems that provide colleagues with updated information available at any time. The results can be introduced in both today’s and tomorrow’s construction sites at various levels of advanced technology. / Sammanhang De senaste hundra åren har vi gett upphov till att bygga infrastruktur i en snabbare takt än någonsin tidigare. Samtidigt ökar kostnaderna för både arbetskraft och byggsektorer som väg- och bostadsbyggnader. Denna situation ger utrymme för autonoma maskiner. Utvecklingen av infrastruktur sker genom effektiva och produktiva konstruktionsmaskiner som successivt moderniseras för att forma samhället. För att öka utvecklingstakten moderniseras både bilar och industri för att möta en mer automatiserad vardag.  Volvo Construction Equipment undersöker det autonoma fordonsutrymmet för nästa generations maskiner. Automationen kompletterar de nya maskinerna och fulländar det mänskliga arbetet med effektivitet, tillförlitlighet och hållbarhet.   Det finns dock en fråga om relationen mellan mänskliga arbetare och autonoma maskiner, jag kommer i denna avhandling undersöka metoder för hur man kan utveckla tillit genom kommunikationssystem mellan arbetare och autonoma maskiner.   Mål Att skapa rekommendationer och lösningar för produkter som bygger tillit mellan mänskliga och automatiserade maskiner på en byggarbetsplats.   Metod Resultatet uppnås genom användandet av fallstudie forskning kombinerat med validerande lärande. Detta innebär lärdomar med hjälp av en iterativ process utav prototyper som testas och valideras.   Resultat Resultatet utvärderar hur förtroende kan utvecklas mellan människor och autonoma maskiner på en byggarbetsplats. Hur kommunikationsmetoder mellan dessa parter skulle kunna genomföras samtidigt som hög effektivitet och säkerhet upprätthålls .   Slutsats Lärandet i denna avhandling tyder på att förtroendet utvecklas över tid med tillförlitliga system som ger medarbetare uppdaterad nödvändig information tillgänglig när som helst. Resultaten kan införas i både dagens och framtidens anläggningsplatser på olika nivåer av avancerad teknik. / <p>Vissa delar är borttagan på grund av konfidentialitet.</p> / ME310 Design Innovation at Stanford University
