The use of insecure networks -such as the Internet- to send and receive information has made the need for preventing unauthorised people reading it yet more important. One of the easiest way to do this is through public key cryptography. However, the problem with this solution is how to tie a specific public key to a certain subject. This is solved by letting a trusted third party issue a certificate that holds, as a minimum, the name of the subject and the subject's public key along with the issuer's digital signature on the information. The rules we make for issuing, revoking and verifying of certificates and the entities that are being used to do so are called PKI - Public Key Infrastructure.

The purposes of litteratur review were to describe patients experiences of living with HIV/AIDS and and their expectations when in contact with care/healthcare. As theoretical frame has Antonovsky, A (1991) salutogenic model, sense of coherence been used. After analyzing the content of the litterature it resulted in 5 categories of experiences and 3 categories regarding expectations. The categories that regards experiences were, to feel frustration and dependance, to switch between hope and despair and suicidal thoughts, to be able to cope with the changing self and to feel social support. The categories that regards expectations were, to feel proffessionalism/competence, to get caring treatment and feeling secure, to feel engagement/individuality in caring.

With a larger awareness of the climate changes and increasing electricity prices, energy efficiency measures in the industry have become more common. By rationalize the activity and by the same time decrease the emission of greenhouse gases the company can both save money and reduce negative environmental impact. For the Swedish industries the electricity price have traditional been relative low, which has resulted in a considerable larger usage than other European countries. By a deregulation of the European electricity market the electricity price will level off between the countries, which will cause a higher electricity price in Sweden than we are use to. To prevent that the Swedish industry don?t lose competitiveness against the other European countries, it will require energy efficiency activities in all different forms.ABB Sweden has decided to decrease their total energy usage with five percent in two years.

The swedish education system in general and the swedish gymnasium in particular is at the point of a thorough reform of the guidelines in education. One major difference given in the guidelines is that the former core subject of arts education is abandoned in favour of making history a mandatory class. This despite the curriculum outlined in 1994 remains. Through comparativ text analysis of the documents and reports outlining this reform and defining the curriculum as well as the guidelines for the education system this study aims to point out the reasons for this change. Through in depth interviews with teachers, educators and authorities in addition to readings of contemporary research on arts in education the study will depict a larger picture of the scheme of things.

Higher demands of competitiveness and efficiency have led to increasing sizes of farms, with more land, more capital and more comprehensive logistics. The aim is to gain benefits of scale economies that reduce the production cost per unit. However, a greater extent of the business exposes the farm of increased risk where small deviations rapidly can erase the benefits. A modern dairy farm thus put high demands on the farmer?s ability to coordinate, plan and manage the forage production through the whole process until storage to obtain silage of the desired quality and quantity at the right price. The objective of this study was to design a simple model, i.e.

The defence unit´s archive stretches over a time limit between the middle of 1971 to the end of 1987. The records the archive mainly contains are concerning the civil defence, inspection and construction of shelters, war- and crisis planning. The majority of the records are registered record, as often is the case with an authority?s archives. The main problems that occurred concerned what should or shouldn´t be public, the principle of provenance and what to prioritize; finish the project before deadline or make sure the records are prepared for a storage that ideally should last for several lifetimes..

The objective of this project is to study how two asperger units, one at a junior school and one at a senior-level school are carrying at their work. I have interviewed one pedagouge at each unit to find out how they organize the education at the units and how they work to develop the students' social skills based on the students' functional handicap. The interviews showed that the following factors are providing the foundation for the pedagouges' work with the students: knowledge of the Asperger syndrome and the symptoms shown by each individual, the pedagouges being explicit and well structured as a professional and as adult combined with him/her being humble and showing respect towards the students and self reflection.Keywords: Asperger syndrome, functional handicap, social interaction, attitude..

The digitization of patient data and medical records used by the healthcare-industry in Sweden is rapidly developing. However; developing and changing things in this field is not an easy task because of the circumstances surrounding it. Digital systems intended to process, and hold, sensitive personal data, such as medical journals, must be developed with laws, confidentiality, integrity and availability in mind to secure that none of this data gets compromised.A complicating factor in regards to this is the fast rate of development within IT in contrast to the much slower bureaucratic process of the justice system. This means that laws and regulations oftentimes aren?t up to date with the newest available technology.With the purpose of establishing set regulations on how patient data should be properly handled the Swedish government enacted the Patient Data Act (sv.

Sweden is on the turn of a dramatic demographic change. The number of elderly will in the coming decade increase considerably. This also means that the need of dwellings adapted for accessibility increases. By adapting dwellings and housing areas to an increased level of accessibility, more people are given the opportunity to stay for a longer time in their habitual surroundings and the housing becomes secure for the user both in a physical and mental point of view. One of the least accessible housing areas in Halmstad is Klackerup.
