XML som informationsbärare för EDI
Information handling has been a key issue for different companies for a long time. Electronic Data Interchange (EDI) is used to transfer different business documents from one company to another. This is done in such way that the information itself is separated from how this information is stored and handled in the companies internal systems. As different companies have different systems there is a need for a standardised format for this exchange. There is a big difference between EDI-systems based on what kind of EDI-standard is used.

Deriving ECA-rules from timed-automata specifications.
Real-time systems are required to answer to external stimuli within a specified time-period. For this to be possible, the systems behaviour must be predictable. The use of active databases in real-time systems introduces unpredictability in the system, e.g. due to their use of active rules. The behaviour in active databases is usually specified in ECA-rules.
IT-relaterade hot - professionella IT-tjänstemäns farhågor och möjligheter
The objective of this thesis was firstly to examine the possibilities of creating a universal tool for evaluating IT-security.

The purpose of this thesis was there after to find and identify threats and counter measures in publications and later discuss these with IT-professionals. We found and identified several threats that the professionals encountered in their work. These threats ranged from techniques used by hackers to threats that can arise when the users on the network are poorly educated.

This thesis consider alternatives for heating and cooling planned office buildings at Arlanda airport. The thesis is divided into three parts where the third part is a shorter synthesis of the two first. In the first part the energy demands of the buildings are modelled in a computer program. Two different building models are created, one more conventional and one with good energy properties. The results shows that with proper construction and ventilation systems etc.
Musikklassifikation ? En jämförande studie av de tre generella klassifikationssystemen DDC, SAB och UDC
The purpose of this Master's thesis is to determine which of the three general classification schemes, DDC, SAB, and UDC is the most appropriate for classifying music documents. This is done by analysing and classifying 60 music documents such as recordings, scores and books about music. The codes resulting from the classification are analysed according to a number of evaluation criteria based on classification theory. The criteria focus on the systems specificity, exhaustivity, exclusivity, helpful sequence, hospitality, notation and that related classes are kept together. The study showed that the systems specificity in classification was of great importance in classifying music documents because of the diversity of music genres.
Lyssna! Sex vuxna individers upplevelser av att berätta om de sexuella övergrepp de har utsatts för i sin barndom.
The aim of this qualitative study was to examine six individuals' experiences to talk about the sexual abuse that occurred in their childhood. We interviewed five women and one man, using a phenomenological approach during the work process. The theories emerged as we analyzed our results and appeared to be communication, cognitive theory, validation, trauma theory and taboo. The results showed that the respondents, whom disclosed the abuse as children, were most likely to get a negative response from both formal and informal support systems. While as adults they were confirmed to a greater extent and therefore achieved a better physical and mental wellbeing.
Bilden av kvinnan i Library of Congress Classification En genusstudie av Library of Congress Classifications första och senaste upplaga
I have done a comparative gender study of Library of Congress Classification from 1900 and 2001. I have also used a hermeneutic method and ideological critics to find out what picture of women the both systems shows. In my comparative study of the both systems I have found low update of classes which relates to women in the new classification system. Men seem to be a norm in the system, because men are not defined in classes related to both men and women. But many classes related to women are named Women as and Women in The study also shows that women are more related to subjects about family and marriage than men are.

Att utveckla medicintekniska informationssystem på rätt sätt : En studie om regulatoriska aspekters påverkan på systemutveckling och IT-innovation inom hälso- och sjukvård
IT is often seen as a solution to many problems concerning effectiveness in organizations. Information systems within the healthcare sector is often viewed as medical devices rather than just systems or services. These medical devices are thoroughly regulated by laws, standards and certifications. In this study I participated in an innovative project that aimed to bring new life and use to the old fashioned patient journal by giving it a visual representation through the use of an avatar. I aimed to study the effects of regulators connected with the patient journal as a source of information for the innovative project.
Etik och censur inom internetfiltrering ? En forskningsöversikt
This paper is a research review in the realm of censorship systems andfiltering systems. It applies ethical considerations to the creation of censorshipsystems bringing forward discussion on the ethics of technology with thepurpose of limiting access to information.There is active research being done in the area of automatic content filteringand censorship systems. These are systems that can filter out undesiredmaterial, typically from the Internet, automatically. Used in some nations,many schools and even mandated in some libraries there are many ethicalquestions raised concerning censorship and access to information.Part of the review concerns the level of accuracy of these systems presentedby researchers in the field and the different approaches used. Reviewedarticles centre around automatic content classification and filtering ofpotentially harmful materials with regards to minors while some relate tocensorship technology in a wider sense.Results show a general lack of discussion concerning the ethics of thetechnology in the research reviewed.
Att erbjuda sanningens ögonblick : En undersökning av bokförlaget Novellix kommunikation och koncept
The Library of Uppsala University has decided to change their classification system from the Swedish SAB system to the American Dewey Decimal Classification. One of the main reasons for this decison was that Kungliga biblioteket also has made an exchange between these systems. Due to that, the national bibliography of Sweden classifies Swedish documents according to Dewey Decimal Classification and the SAB system is no longer maintained. A transition to Dewey Decimal Classification will enable Swedish librarians to import foreign catalouge posts and classification codes and will provide them with a common standard between their libraries and other libraries due to the use of the same international classification system. It is disputed whether the Dewey Decimal Classification is equally suitable for all subjects.
GRÄNSSNITTET OCH ANVÄNDARNA En undersökning av två gränssnitt mot en bibliotekskatalog.
The scope of this master´s thesis is the issue of usability in relation to interface design,in particular the interface of a university library´s online public accessed catalogue, orOPAC. Since the OPAC can be seen as the library´s ?shop window? to the world, it isof great importance that the interface to the OPAC can be used by patrons witheffectiveness, efficiency and satisfaction.The master´s thesis is based on a qualitative study performed at Karolinska InstitutetsUniversity library, and contains both a usability evaluation and an interview study. Twointerfaces were evaluated: a standard web interface provided by the system supplier, andan interface developed in-house by Karolinska Institutet´s systems department. The twointerfaces are both connected to the same online library catalogue, thus making possiblea comparative study..
