Current research shows that the number of door openings during surgery is unjustifiably high. It is the operating room nurses task to ensure a hygienic and aseptic environment throughout the surgery with the goal of minimizing the risk of healthcare associated infection. The study aims to investigate whether the operating room nurse is attentive to the number of door openings during surgery and if the operating room nurse is attentive to the reasons behind the door openings. A pilot study with nine observations was carried out on two smaller hospitals in the region of Västra Götaland. The results showed a significant underestimation of the rated door openings compared with the actual ones.

ABSTRACTIntroduction: Postoperative wound infection is the third most common nosocomial infection in Sweden. The ever-growing problem of antibiotic resistance provides surgical departments a big challenge when it comes to preventing the spread of infection. Operating theatre nurses have a vital role in the prevention of infection. In addition, correct ventilation in the operating theatre is of great importance. The caregiver is responsible for quality assurance of ventilation in the operating theatre, but the work can be delegated to other staff within the department.

There are some key elements which distinguish a general operating system, such as Linux, from a Real Time operating system, such as OSE. The later belongs to the category of soft Real Time systems while Linux is a general operating system, with significantly improved real time properties after version 2.6. These improvements make it interesting to compare the two systems.When comparing two operating systems, there are a number of issues which have to be considered. One way to measure the performance of the systems is by studying the time consumption for the same functionality and hardware.During the study, the items that appeared as the most important for the performance of the systems, were: process primitives, system primitives, interprocess communication, context switches and interrupt latency.This work demonstrates that it is possible and reasonable to do performance testing on two different operating systems. The implemented tests cover a number of basic functionalities, which appeared to be the most crucial ones for the performance of the systems..

With the huge amount of computers connected to the Internet the IP-addresses are starting to run out. The Internet Engineering Task Force, IETF, have decided that it is about time to exchange the old 32 bits Internet protocol, Ipv4, to a more modern 128 bits protocol called Ipv6. This thesis explores the possibility to install Ipv6 in different operating systems. By testing various operating systems and by set up criteria compare them to each other we give the reader a picture of how the installation is done. We also show which operating systems to prefer if you want to use IPv6.

The aim of this thesis is to examine what factors that influences the management control in a family business operating in a sector in which they are under-represented. We have therefore conducted a case study of a family business in the finance sector, E. Öhman J: or Fondkommission AB (Öhman). The first conclusion is that the management control in Öhman is influenced by the environment and the increasing size of the company. We have found, however, that it is to an even larger extent affected by the fact that it is a family business even though the company is operating in a sector in which family businesses are not the norm.

This thesis provides a descriptive study from a pedagogic perspective that analyzesobjectives, directives and content related to the social science core class, SAMSAM01b, atGothenburg public high schools. The purpose is to further explore the role of education inrelation to global development and international relations. The study is built aroundcurriculum representation and course implementation of three aspects considered importantfor global development and knowledge of the Operating environment: critical thinking,international cooperation and sustainable development. Knowledge theory and likemindedideas of what constitutes a good education form the core of the study?s theoreticalperspective.

ABSTRACT (english)Introduction: The possibility to transplant an organ is an important part of the health care system, which demands great resources and a well functioning organization with a level of high competence. The work with organ donation is complex and brings forward a great amount of different emotions for the operation room nurse. Aim: The aim with the study is to illustrate the operating room nurses experience when the organ donor is brain dead. Method: Data collection has been performed with semi-structured interviews, which have been interpreted by qualitative manifest analysis. The design of the study is pilot towards a study in full scale.

The DuPont formula is one of the most well known and basic tools used for financial statement analysis and is highly useful for understanding firms strategies and Operating environment. Previous studies on American listed companies have also shown that analysis of the changes in the DuPont components is useful in forecasting contexts. In this thesis we test whether disaggregating the change in return on net operating assets provides incremental information about future performance for Swedish listed and not listed companies. We find that the change in asset turnover is a leading indicator of increased profitability for both listed and private companies, regardless of size. We also find evidence that the usefulness of the disaggregation for understanding future performance is greater in capital intense industries and lesser in service industries..

Background: As companies are operating in more globally and complex environments, the need for risk control is accelerating. In an ever-changing environment, companies cannot merely focus on traditional risks, which include financial and insurable risks. To maintain competitiveness, companies need to extend their risk management to include all risks, traditional as well as operational and strategic risks. Purpose: The purpose is to describe and position risk management for Telecom operators, in comparison with the risk management literature, with regards to structure, processes, learning process, visions and benefits. In addition, our aim is to link risk management perspectives with the different strategies for knowledge management.

This study examines how a company adapts its operating control when the environmental circumstances are changing. This is a case study with a qualitative approach which is based on interviews. The main purpose is to examine how an accounting firm adjusts its operating control in order to meet the abolishment of the statutory auditing. Another purpose is to describe how the abolishment of the statutory auditing will influence or have influenced the choice of measures in the balanced scorecard. The question this study aims to examine is: How do audit firms adapt its operating control in order to meet changes in the environment? This question lead to a second question which the study also aims to examine and is How is the abolishment of the statutory auditing influencing the accounting firms goals, measures and focus in the balanced scorecard? The conclusion of this study shows that the abolishment of the statutory auditing has had an influence on the balanced scorecard.

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.

The dry out criterion (MCPR) has been calculated for the most limiting H2-events for Forsmarks unit 2 and 3, at operating points that are normally not analyzed before each cycle. The operating points that normally are regarded as the ones with the lowest margin to dry out are the ones where the thermal power is the highest at agiven recirculation flow. This report shows that this is not the case for Forsmark 3. MCPR-values at partial power operating points are higher for the limiting case inside rather than on the boundary of the region of operation. It is therefore recommended that the method for determining the dry out criterion for Forsmark 3 is revised to account for this effect.

 The purpose of this study was to study how surgical nurses experiences their work order in the operating room (OR), and how they experience their psychosocial work environment and work organization in terms of hierarchical structures..

ABSTRACTPressure ulcers are a serious health damage that causes great suffering, prolonged hospital stays and increased health care costs. Patients undergoing surgery are at high risk of developing pressure ulcers and it is the operating theatre nurse responsibility to protect against health damage through nursing. There are little research made in the area of perioperative pressure ulcer prevention. In order to investigate perioperative pressure ulcer preventive care measures that are described in the litterature and to answer the question how the operating theater nurse can protect the patient, a pilot study of a systematic literature review was carried out. Data base searches were conducted in PubMed and Cinahl from where ten articles were selected and examined for their quality and content.
