Hygien är en viktig del av sjukhusvård och det finns många utarbetade rutiner och föreskrifter. Då det tekniska kunnandet ökar, ges möjligheter till fler och mer avancerade kirurgiska ingrepp och när krav ställs på kostnadseffektivitet, ökar risken för vårdrelaterade infektioner. Att kunna förebygga och förhindra smittspridning på en operationsenhet är därför av största vikt. Studiens syfte var att undersöka faktorer som kan minska postoperativa infektioner inom operations-sjukvård. Metoden har varit litteraturstudier och baseras på 20 vetenskapliga artiklar.

This thesis describes new methods for automatic crack detection in pavements. Cracks in pavements can be used as an early indication for the need of reparation.Automatic crack detection is preferable compared to manual inventory; the repeatability can be better, the inventory can be done at a higher speed and can be done without interruption of the traffic.The automatic and semi-automatic crack detection systems that exist today use Image Analysis methods. There are today powerful methods available in the area of Computer Vision. These methods work in higher dimensions with greater complexity and generate measures of local signal properties, while Image Analyses methods for crack detection use morphological operations on binary images.Methods for digitalizing video data on VHS-cassettes and stitching images from nearby frames have been developed.Four methods for crack detection have been evaluated, and two of them have been used to form a crack detection and classification program implemented in the calculation program Matlab.One image set was used during the implementation and another image set was used for validation. The crack detection system did perform correct detection on 99.2 percent when analysing the images which were used during implementation.

Active work to increase the efficiency of energy use is taking place in Sweden and throughout all of Europe. Electricity is an important part in our society?s energy system which means that the electrical grid operators and associated therewith has a central role in this work. Monitoring and controlling the electrical grids are managed from the distribution system operator?s DC, dispatch center.The aim of this report is to examine how the operations in a typical DC on the Swedish electricity distribution network will look like in five to ten years.

In 1985 the Swedish Association of Local Authorities and Regions published a paper on recommended depreciation time on capital assets for the public sector. This paper should only be seen as guidance, but many municipals use it without any further investigations. Swedish municipals are not like private companies; one very distinguished difference is that they are not allowed to make any profit. The municipals in Sweden are regulated by the constitution law which means that they can not go bankrupt. The public and the private sector have different legislations that result in different ways on how they for example treat depreciations.

Doktriner utgör väpnade styrkors viktigaste beskrivning avseende hur man avser använda militära medel för att uppnå politiska mål. För att tjäna sitt syfte bör doktriner utvecklas med rationella utgångspunkter som omvärldens utveckling och senaste forskning. Dock menar många att andra faktorer sprungna ur kulturella traditioner och organisationers särintressen påverkar tillkomsten av doktriner.Civil-militärt samarbete har i moderna konflikter blivit allt mer betydelsefullt. Strategier för fredsfrämjande insatser i dagens komplexa konflikter bygger i allt högre grad på integrerade insatser mellan flera olika funktioner och aktörer. Civil-militärt samarbete har dock traditionellt haft en underordnad, stödjande roll i militära organisationer.I denna uppsats undersöks forskningens roll i doktrinutveckling.

Due to the obvious fact that one can never be hundred percent sure of what's hiddenunder the ground surface, construction work is naturally hard to project.However, many of the work methods are executed in the same way on variousprojects. The department of construction work at JM AB region öst describes a lackof follow-ups and feedback between the calculators and production managers.In this thesis we have studied the communication between these groups and alsohow they share experiences and knowledge. In order to get the full pictureof the day-to-day operations we used three methods to gather information. Studyingliterature gave basic knowledge of theories about feedback, and thenecessity of working with giving feedback. In order to understand the process ofconstruction work we made several interviews, both structured and nstructured.

AbstractThe aim of our study was that from a Preschool Manager?s perspective to describe, analyze and understand the function of special education and the Special Education Teacher?s profession within preschools. We conducted twelve interviews with Preschool Managers in two northern Swedish municipalities. From a theoretical base, we used both the relational and categorical perspectives. All answers from these interviews have been analyzed from these perspectives.

The aim of this study is to investigate into the use of discussions in the classroom to help the pupils develop a deeper understanding of mathematical concepts and operations. The empirical data contain interviews with two teachers and observations from their lessons. The purpose of the interviews was to find out what importance the teachers ascribed to the ability of their pupils to talk about mathematics, and how they organised their classes to encourage mathematical discussions. With the observations, I was able to see the interaction in the classroom and hear discussions between the teacher and the pupils, as well as between the pupils themselves.The interviewed teachers proved to share my own belief in the results of researchers like Malmer (1999) and Löwing (2006) about the importance of verbal discussion, argumentation and reflection during mathematics classes. But convictions derived from the research of others are one thing, the practical application of the wisdom in the classroom another.

SUMMARYPrevious research has shown that there is a connection between the doorways and postoperative wound infections. Despite recommendations from Socialstyrelsen and the individual hospitals' PM there is still high traffic in the operating theatres. In a hybrid theatre environment combined X-ray techniques of surgery, resulting in it being further two categories inside the operating theatre. This may generate an increase in traffic flow. The study is a prospective, non-participant observation study conducted in the spring of 2013 at a university hospital in western Sweden.

This is a study on the outcome of the Swedish Forest Agency´s mission to provide individual advice to private land owners about precommercial thinning. The study was conducted in Sala municipality and included forest owners that had received private individual advice from a Swedish Forest Agency consultant as well as forest owners that had not received individual advice. One of the central issues was to make comparisons between these two groups. The survey was carried out by telephone interviews combined with a smaller field study. The questions were designed to provide information about to what degree the forest owners had been affected by the advice and if there had been a change in the way in which precommercial thinning was performed. In terms of the amount of precommercial thinning that had been carried out, no statistically significant differences were found between the two groups.

AbstractFor an audit organization, it is important to work toward maintaininga high error climate to handle errors in an efficient and propermanner. This means that it is important for accountants to worktowards high quality of work, reduce and manage errors that mayoccur in their daily work. Therefore, auditors must know how tohandle errors in order to improve efficiency, which can be affected byhow leadership is exercised in the workplace. The error climatemeans being able to act in a manner which will ensure a good jobtowards customers but also within the internal operations.The ethical leadership may thus have an impact on how auditorshandle the error environment both internally and externally. It is veryimportant for customers to have confidence in the business but also tomaintain the order and the general rules of society for accountingfirms.My study aims to show the thinkable relationship between ethicalleadership and the error climate.

Lean production is the name given to Toyota?s Production System (TPS) by the west. The continuous improvements of their operations through Lean has made Toyota into the largest car manufacturer in the world. This, in turn, has led to several studies regarding both Toyota and their system as to find ways to apply Lean in other organizations. Even so, over 90 percent of all companies fail to implement Lean.

Minvapnet klassas fortfarande som en viktig faktor vid strid, dock har dess utveckling i den svenska Försvarsmakten hamnat i skymundan. Denna slutsats kan man dra om man ser till vilka uppgifter och vilken utrustning som i dagsläget finns för att minera. De hjälpmedel som finns och är brukbara är ytterst begränsade. Ett system som skulle kunna vända denna trend är en minkastare, något som bland annat tas upp i, för fältarbetesfunktionen, interna utvecklingsplaner.Syftet med denna uppsats är att undersöka huruvida Försvarsmakten skulle kunna nyttja ett minkastarsystem, vad det skulle innebära för Försvarsmaktens förmåga att minera samt lyfta upp vilka kriterier ett sådant system skulle behöva leva upp till för att kunna nyttjas av svensk trupp.Huvuddelen av uppsatsen kretsar kring textanalyser av aktuella reglementen, styrdokument och utredningar. I och med den nära knytningen till Försvarsmakten används de grundläggande förmågorna som analysverktyg och som teorikoppling.Uppsatsens resultat påvisar att införandet av ett sådant system skulle utveckla arméns, och framförallt då ingenjörförbandens förmåga att minera.

AimThe purpose of this study is to, from a perspective of a PE teacher, look at how teachers of physical education in elementary school designs and assesses the teaching of swimming. The issues underlying the study are as follows:Which elements are included in the swimming education and how do teachers work with these operations?What does the PE teachers classify as swimming ability and what do teachers experience as obstacles for the students development of swimming ability?How do the PE teachers interpret the knowledge requirement in Lgr 11?MethodThe study is based on six interviews of qualitative nature, with PE teachers from various municipalities in the region of Mälardalen.ResultsThe result yielded by the study is that the swimming classes can take different forms depending on whom the teacher is. Common to all the teachers in the study is that they teach emergency management and lifesaving. When it later comes to teaching how to swim and practice, the teachers who teach in the younger age groups work more concentrated and continuously with swimming, while the teachers who work with the older age groups just checks whether students can swim or not.

To be able to compete on the market environmental Management System has become an important part of operations work. However, many companies still haven?t implemented an environmental management systems due to lack of time and the high costs. One of the companies with this problem is Falu Bildemontering. Their goal is to accredited according to the ISO 14 001 certificate.
