This paper is partially a literature study of human error and interruptions and partially an investigation of pilots and Air Traffic Control. The aim of the investigation was to find out where interruptions occur and how to reduce or eliminate them. The objective of this paper was to investigate what type of interruptions pilots and ATC deals with and during which phases they occur. The paper has revealed that private pilots causes more interruptions for ATC personnel than commercial pilots. The cause for this is probably the less experienced private pilot and the fact that Swedish is used before English by private pilots in communication with ATC.

Bara BostäderPlacerat mellan Bollmora flerbostadshus och den gamla landsvägen breder Tyresögymnasium ut sig. Vår ingång blir atr riva skolan, materialet ´kremeras´till tegelkross och sprids i en röd löparbana längs med den befintliga landsvägen, att tillåtas glömma för att senare minnas. Gymnasiet förstås som en del av det befintliga landskapet, det ändrar bara from och byter plats. Vad händer om man släcker ett lager i AutoCad?Det närvarar i sin frånvaro. Djup genom lager.

This master thesis is a study on how a rategyro triad, an accelerometer triad, and a magnetometer triad can be integrated into a navigation system, estimating a vehicle?s attitude, i.e. its roll, tipp, and heading angles. When only a rategyro triad is used to estimate a vehicle?s attitude, a drift in the attitude occurs due to sensor errors.

Aphasia is a disease that brings on disability. The purpose of the study is to describe the daily life when afflicted with aphasia and gain a deeper understanding of persons with aphasia in working ages. The study was made with a qualitative approach with a combination of data sources; literature, internet lectures, live lectures, interviews with personnel in medical and educational services and three persons with aphasia. More research in aphasiology is welcome. This may be aimed at developing knowledge about the importance of communication, of active participation in the social environment, and the achievement of improved attitudes towards people with disabilities. The study should give rehabilitation actors and close relations knowledge and support in their action when they meet people with aphasia..

Our essay is about alcohol information given to youths in Helsingborg. It is a research to find out how the message is communicated and how it is presented. The purpose of our study is to find out, why inform about alcohol and if it is taken in a preventive aim. To investigate weather there is any talermade information in the community for youths between 12-18 years old. We also want to know if the given information is destined for a special group/groups or is it for young people in general? Our intention is to find out the meaning of prevently information about alcohol and if it is possible to reach a change in attitudes and behaviour.We use a qualitative method and have interviewed twelve persons with different occupations within medical service, local authorities, public and private schools and voluntary organizations..

In inhalation anesthesia life-support systems are used to provide gases to the patient and to monitor important parameters. These systems are used in dynamic and stressful situations where the information-load on the operators often is significant. This thesis presents a design concept of an anesthetic system. The design goal has been to keep the information-load on the operator low with the objective to minimize confusion and error.A number of contextual inquiries were made in the operating room during surgery at four hospitals in Sweden. The goal was to understand the actual use-situations when anesthetic systems are employed.

What are the competencies and qualifications required by employers concerning the first line executives in medical care? In this paper we aim to scrutinise this question by analysing the significance of terms reproduced by employers in advertisements between 1971 and 2007.Our survey concerns 93 advertisements and two interviews with knowledgeable authorities on personnel administration in the county council of Jönköping municipality, Sweden. Using a theoretical framework developed by Ellström our results point out how the demands of the employer have changed starting in the 1970?s. We set fore, as a way of conclusion, the setting of competency and qualifications required by the employer have not only increased but appears much more comprehensive and far more complex than ever before..

Författarna till examensarbetet har intervjuat tre företag som tillsammans lämnade in över 15 000 förbättringsförslag år 2010. Avsikten med examensarbetet var att finna exempel på hur företag arbetar med Ständiga förbättringar i praktiken.Examensarbetet påbörjades med en litteraturstudie med Ständiga förbättringar som bas. Litteraturstudien fokuserade på implementering av Ständiga förbättringar, dess framgångsfaktorer och fallgropar. Efter detta genomfördes intervjuer på tre företag med en kvalitetsansvarig och en operatör i den mån det gick. Staffan Olsson, Operation Excellence Manager på Coca-Cola Enterprises Sverige AB, Håkan Lööw, Operations Manager, och Mulugeta Gerzgher, teamleader på sterilavdelningen på St.

Denna uppsats är en del av trafiksäkerhetsprojektet FICA (Factors Influencing the Causation of Accidents and Incidents), vars målsättning är att genom en förståelse för förarbeteende kunna utveckla aktiv säkerhetsteknologi för fordon. Inom detta projekt kommer en metod för olycksanalys, DREAM (Driving Reliability and Error Analysis Method), att användas. Den här uppsatsen handlar om att utvärdera och utveckla denna analysmetod. Arbetet med metoden har främst gällt användbarhetsaspekter av DREAM. Även olika kvalitetsaspekter som till exempel replikerbarhet, har undersökts.

Studiens syfte är att studera de bakomliggande sociala faktorerna som kan bidra till utvecklingen av datorspelsberoende. Studien genomfördes kvalitativt genom att intervjua fem personer som själva ansett sig vara datorspelsberoende. Tidigare forskning som berört detta ämne har handlat om hur användare påverkas av spelet, och inte vad som lett fram tillatt det intensiva spelandet påbörjades. Som teoretisk utgångspunkt för studien valdes den utvecklingsekologiska modellen som användes för att studera individen utifrån ett mikro-,meso-, exo-, makroperspektiv. Våra data visar resultat främst på en mikronivå där vi fann att en problematik på denna nivå fanns genomgående för samtliga informanter.

This thesis lays the foundation of the future routines of effective error repotring fortraffic devices in the raiway sector.If a device, for example a timetable display, stops working it is vital that the device isfixed as fast as possible so that the travelers dont miss any important information.The methods that are used today are old and not very effective. It can take time forthe repairmen to find the right device or locating the broken component. At the sametime he is supposed to maintain telephone contact with central control throughoutthe whole session.The need for a new, more effective, system is vital to make the whole repair pfocessmore effective and let the repairmen work without having to contact the centralcontrol by phone.I started this work by examining the possibilities of assigning every object with aunique identifier (ID tag) that could be accessed by a manual scan device. The ideawas that the ID tag could holw information about the object and be obtained byscanning the ID and get the information presented on a mobile device.The work also included building a internet application that enabled the reader to seeand change the information on the ID tag.The result was a database that stored information of different objects which could beobtained by scanning the ID tag and presented by a internet application..

When traffic in large cities increases, it becomes more vulnerable to disturbances such as accidents, stalled vehicles or construction; therefore, traffic jams are more likely to occur. For better control of the traffic at a disturbance the Swedish National Road Administration (SNRA) has traffic equipment which can be controlled from a command centre. This traffic equipment consists of gates and signs with variable messages. This report will discuss the system used for traffic control in Stockholm. It will present proposals designed to improve it.

Denna rapport beskriver framtagande av ett koncept för ett geografiskt informationssystem som är anpassat för att köra på moderna mobila enheter ute i fält. Detta sätter krav på systemet vad gäller beräkningskraft, lagringsutrymme samt möjligheten att klara av intermittent datakommunikation. För att ta fram systemet utfördes först en förstudie med databaser och sökmotorer användes för att hitta relevant information och relevanta artiklar som kunde hjälpa till vid framtagningen av systemet. Denna fakta tillsammans med utförda tester och ?trial-and-error?-programmering ledde i slutändan till ett koncept som klarade av de krav som ställdes på systemet.

AbstractThe purpose of this study was to identify problems that may occur in the execution of a civil engineering project and suggest measures to reduce the risk of errors. The study was conducted in cooperation with a civil engineering company in the Gothenburg area. During two weeks in February 2012, a field study took place on two construction sites where disruption and problems that took more than 15 minutes to correct were noted. During the field study we identified 39 such occurrences in the projects and then these were classified into different categories according to their cause.The two largest categories were "Design" and "Planning", which accounted for half of the errors that were discovered.In the study results were evaluated to decide whether it was possible to detect discrepancies at an earlier stage. The cost to fix an error in the design stage may be significantly less than to correct the problem in production.According to the evaluation, 55% of the errors could have been detected earlier if there was a greater degree of observation for such issues by everyone involved in the project.
