Digitala signaturer - ett verktyg för säkerhet?
Statliga myndigheter använder i allt större utsträckning öppna system, så som
Internet, i sin kommunikation med medborgare, företag och andra myndigheter,
därmed ställs allt högre krav på säkerhet och tillit. I takt med den ökade
användningen av elektronisk kommunikation uppstår nya problem. Några av dessa
är att vi inte med säkerhet vet vem vi kommunicerar med, vem som beställer
tjänster och att vi inte kan vara säkra på att information kommer till rätt
person eller har ändrats på vägen. Verktyg som finns för att lösa dessa problem
och öka säkerheten är digitala signaturer och elektronisk identifiering.
Med detta som bakgrund ställde vi oss följande frågor, vilken teknik ska
statliga myndigheter använda för elektronisk identifiering och signering?
Vilken teknik ska användas för att uppfylla kraven på säker elektronisk
överföring? Kan statliga myndigheter ersätta traditionella namnunderskrifter
med kvalificerade elektroniska signaturer? Syftet med vår uppsats blir därför
att i första hand redogöra för hur statliga myndigheter avser att ersätta
traditionella namnunderskrifter med kvalificerade elektroniska signaturer.
Genom litteraturstudierna skaffade vi oss kunskaper om både teknik och
användningsområden för digitala signaturer och genom att beskriva dessa
tekniker får läsarna en introduktion i ämnet.
Computer Network Attack som olovligt våld : en fråga om association, effekt, aktör och mål
I Estland 2007 utbröt vad som kommit att kallas ?Cyberwar I?, vari ett stort antal centrala myndigheters, tillika finansiella institutioners servrar attackerades av massiva så kallade Computer Network Attacks (CNA), utfört av framförallt ryska aktörer. Estland protesterade högljutt, men frågan huruvida CNA är att beteckna som olovligt är allt annat än klar. Prövningen sker mot den folkrättsliga regimen Jus ad Bellum, och huruvida metoden uppfyller vissa centrala begrepp. Men hur skall denna regim appliceras CNA?De frågeställningar som avses besvaras är: hur kan CNA utgöra våld eller hot om våld i enlighet med FN-stadgans artikel 2(4) samt hur kan CNA utgöra väpnat angrepp i enlighet med FN-stadgans artikel 51? Detta avses göras genom en studie inbegripande flertalet folkrättsliga experters teorier på området CNA och våldsanvändning, samt applicering av desamma på en fallstudie av händelserna i Estland 2007.Sammanfattningsvis konstateras att flertalet variabler har bärighet i hur CNA kan uppfylla artiklarnas centrala begrepp, vari frågan om association, effekt, aktör och mål tydligast faller ut.
Vidareutveckling av AppCMS
I denna uppsats kommer vi dokumentera vidareutvecklingen av Softwerk AB?s Content Management System kallat AppCMS. I dagsläget innefattar AppCMS plattformarna iOS, Android och Windows Phone. Kunderna till Softwerk AB har dock uttryckt ett behov av att även kunna nå ut till sina användare med en webbaserad samt en utskrivningsbar lösning. AppCMS?s exportformat har därför analyserats för att undersöka möjligheten till att återanvända det existerande exportformatet från AppCMS även för dessa plattformarna.
IKT och Pedagogik : En kvalitativ studie om datorbaserad undervisning och elevutveckling utifrån språklärares perspektiv
The purpose of this paper was to investigate the foremost teachers thinking of computers in teaching, how they work practically with computers as a tool, and if it is reflected in the students' school performance. To carry out this study, I used qualitative interviews as a method and I have interviewed four teachers where two works at the high school and two in upper secondary school. Both schools use computers in teaching as a supplementary tool for teaching materials. All teachers have similar ideas regarding what purpose one should use the computer and in which way, but the important thing is that the teachers and students receive an introductory course in how to use computers. Educators agree that this approach is and can promote students' language and knowledge regardless of the subject.My informants have come up with own methods that they use in the digital classroom including Skype, YouTube, Facebook and flippedclassroom where one can learn from other educators working.
Kopieringsskydd och lagar - rätt väg i kampen mot piratkopieringen?
Det rapporteras mycket om piratkopiering i massmedia idag. Vem som helst kan
med inte alltför stora kunskaper eller kostnader kopiera film, musik, spel och
programvaror, som dessutom ofta är lättillgängliga på Internet. Hur stort detta
problem är och för vem, är det nog ingen som riktigt kan förstå eller svara på.
Organisationer och företag inom branschen försöker med olika medel hantera
trenden med att kopierad digital information får en allt större spridning och
efterfrågan bland konsumenter. Detta genom att framställa bättre och bättre
kopieringsskydd och genom att arbeta för skärpt lagstiftning kring
upphovsmannarätt för digitalt baserade produkter.

The need arose after demand from the government due to a seriesof incidents that took place during the revision of the nuclear power plant in year2009.The task of the project has been to create a computer program that can generate agraphical representation of the electrical components relations. The basis for theprogram has been an example of how the client wants the graphical representation tolook. During the course of the project weekly meetings have occured in which theclient has reviewed the work.The result of the project is a program written in Visual Basic Applications that can berun in Microsoft Excel. The program is capable of generating graphics for a majority ofthe cases.
Dåtid, nutid och framtid : Hur arbetar dagens historielärare i grundskolans senare år med historiemedvetande?
The theme of this essay is literacy training in pre-school. The theme takes it starting point in a project, where my colleagues and I noticed our children playing with writing and symbols. It leads to an exciting, reflecting and developing project, a project that will go on for six months together with twenty children in the age of five and six.The essay describes how I and the rest of the staff work with the project, and also how we try to find challenges that are meaningful for our children.

Fyra lärares föreställningar om oordning i klassrummet : en studie om lärares förväntningar och elevers behov och motivation
The purpose of this study was to examine how four teachers with different teaching experiences treat and think about insubordination in school. The study emphasizes on questions like: When and why does disorder occur? How do the teachers manage disorderly conduct in the classroom? and Could there be a conflict between the teacher?s expectations and management, and the needs and motivation of the pupil? It was evident through interviews with these four teachers that their statements could be divided into similar themes which subsequently could be put into the motivational structure of Abraham H. Maslow. The conclusion of the study was that teachers may possibly have a better chance of managing disorder in their classroom if they are aware of the connection between disorderly conduct and a person?s needs and motivation. .
Geografiperspektiv
AbstractOur world is facing new challenges depending on the climate changes. The UN panel of climate changes has determined that the human race is responsible for the changes, but also that we have the opportunity to reduce the effects. This demands that the information reaches out to the public which means that the school system carries major responsibility to this type of questions. This also means that the teachers have to be observant, and give the questions the attention which is needed. The purpose of this essay is to see if this awareness exists today among active teachers and teacher students and if the perspective differs among them, but also their opinions is in agreement with the course plan in the subject.
