ISIT-modellen : Vägledning för att realisera en verksamhets informationssäkerhetsmålLarsson, Elina, Olin, Michael January 2004 (has links)
The ISO standard ISO/IEC 17799/SS-627799-2 is a guidance for organizations to realize their information security goals. In spite of this standard, studies show flaws regarding information security in organizations. In particular flaws regarding overall view, knowledge and clear roles and responsibilities have been observed. The ISIT (Information Security Integrated Three level) model and its guidelines, developed in this thesis, help organizations to identify the required processes and procedures as well as the logical process flow. The thesis is based on theoretical studies and a case study within a multinational company. The results of the case study show great lacks in defining roles and assigning responsibilities, but also in overall view and knowledge regarding processes and the process flow. The thesis develops a model to facilitate an organization’s initiation of the ISO standard and to help solving the identified flaws. The ISIT model is based on the ISO standard, but expands the PDCA model and integrates it with the controlling documents related to information security management. The expansion of the PDCA model gives a clearer flow, where all the processes related to a management system are included. This enables clarity and faster overall view regarding the information security organization. The integration of the controlling documents means that the processes can be divided into procedures at different levels of the organization. This provides a possible solution to the definition of roles and to the assignment of responsibilities. Guidelines on the identification of processes and roles can not be found in the ISO standard. Therefor the ISIT model should be used as a complement to the ISO standard and will help organizations to reach their information security goals.

En fallstudie av fritidshusets inkludering i den kommunala planeringen / A case study of second homes inclusion in the municipal planningOlofsson, Emil, Jards, Emil January 2022 (has links)
Tillgången till fritidshus bland Sveriges befolkning har successivt blivit större. Idag har över hälften av alla bosatta i Sverige möjlighet att besöka ett fritidshus. Det gör att kommunerna bör inkludera fritidshus i den kommunala planeringen. Uppsatsen syftar till att undersöka och problematisera fritidshusets inkludering i den kommunala fysiska planeringen. Utgångspunkten är två frågeställningar som undersöker i vilket sammanhang kommuner diskuterar fritidshus och vilka ekonomiska aspekter som beaktas vid planering förfritidshusbebyggelse. Det teoretiska ramverket behandlar hur konvertering av och tillfritidshus skapar möjligheter och problem för kommunerna. För att förstå fritidshusets roll i det svenska samhället och vilken kravställning som finns på den kommunala planeringen belyser teorin och tidigare forskning hur fritidshuset definieras, dess geografiska placering i samhället, fritidshusets koppling till turism och slutligen kommunens planeringsansvar. Metoden som används för att besvara uppsatsens frågeställningar är en kvalitativ innehållsanalys av kommunernas översiktsplaner och andra planeringsdokument som nämns idenna. De studerade kommunerna är Karlstad, Torsby och Kristinehamns kommun som ligger i Värmlands län. För att komplettera dokumentstudien genomfördes en semistrukturerad intervju med en samhällsplanerare från varje kommun. Empirin redogör för i vilket sammanhang fritidshus diskuteras i kommunala planeringsdokument samt vilka ekonomiska aspekter som beaktas i beslut om fritidshusbebyggelse. I analysen framgår det att fritidshus framhävs i flera avseenden men att den får störst inkludering i plandokument när en konvertering diskuteras. Denna diskussion sker främst i samband med fritidshus som är placerade på attraktiva platser där målsättningen är en omvandling till permanentbostäder, alternativt en omvandling av permanentbostäder till fritidshus i anslutning till besöksmål för rekreation. Infrastruktur är en avgörande faktor när fritidshusbebyggelse planeras. I sambandmed fritidshus i LIS-områden är den ekonomiska aspekten viktig där det krävs befintlig bebyggelse för att kunna motivera ytterligare exploatering av området ur ett ekonomiskt hänseende.

Striden om stranden : LIS-dispensernas politik och praxis / The Battle about the Beach : LIS exemptions in politics and praxisHolmgren, Johan January 2020 (has links)
Denna uppsats undersöker hur olika aktörer inom politik och juridik ser på landsbygdsutveckling i strandnära lägen, så kallade LIS-områden, som syftar till att bidra till landsbygdskommuners ekonomiska och demografiska utveckling i strandnära områden. Det empiriska materialet består uteslutande av domstolsreferat från Mark- och miljööverdomstolen samt riksdagsdebattprotokoll mellan åren 2012–2019 som analyserats kvalitativt. Sammanfattningsvis verkar naturvärden spela en liten roll vid juridiska överväganden om strandskyddsdispenser i strandnära lägen. Däremot används naturen och landskapet som argument för politiska ståndpunkter för eller emot ett förändrat strandskydd. En annan slutsats som kan dras från analysen är att länsstyrelserna i många fall hamnar i kläm mellan juridik och politik när man överprövar strandskyddsdispenser i landsbygdskommuner. Slutligen förefaller den allmänna politiska viljeriktningen i riksdagen idag gå mot att kommunerna delegeras mer makt till självbestämmande kring byggande i strandnära lägen och att strandskyddet kommer att bli alltmer selektivt i framtiden. / This essay explores how various actors within politics and law look upon rural development at waterfront locations, the so-called LIS-areas, which aims at contributing to the rural municipalities’ financial and demographic development in riparian areas. The empirical material is exclusively based on court reports from the Land and Environment High Court in Sweden and debate records from the Swedish Parliament between 2012-2019 which have been analysed qualitatively. In summary, nature seems to play a small role in court decisions about exemptions from the riparian law. However, nature and scenic landscapes are being used as political arguments for or against exemptions from the riparian law. Another conclusion from the analysis is that the Swedish County Boards are pushed into a tight corner between law and politics when they retry exemptions from the riparian law in rural municipalities. Finally, there is a common political direction of will, in the Swedish Parliament today, towards delegating more power to the municipalities for deciding on building in riparian areas and that beach protection will become more selective in the future.

Lis LKDS 630 / Press LKDS 630Humpolíček, František January 2018 (has links)
Final thesis on the design of the drive of a cutting mechanical two-point crank press with a nominal force of 6300 kN. After the theoretical definition of the area of mechanical crank presses and their drives at the beginning of the work, the actual design solution follows. The main idea of the design is the drive arrangement with the concurrent axis of the clutch shaft. The supplied torque is distributed on two longitudinally mounted drive units via a two-sided bevel gear. Solution of the construction design is aimed at enabling workspace variability while simultaneously unifying the maximum number of drive components. Drawing documentation of selected components and assemblies is the part of the thesis.
