The background for this degree thesis is a need to replace the existing seal used to protect equipment containing secret or sensitive equipment used by Swedish Defence. The target design should satisfy both the need for tamper evidence and reduce Life Cycle Cost. In developing a new design for a seal, additional benefits such as improved logistics support and indication of attack methods such as heat and solvents have been considered. The lack of guiding principles for end users of seals became evident during the interviews. Major concerns for the future are education of users, information about actions if a seal is broken and user liability. The design work was divided into several phases. A feasibility study was performed including investigation of theory of labels, materials and possible technologies. The feasibility study also includes a requirement analysis based on interviews. This analysis was later used as a tool for evaluating different concepts. Using the list of construction criteria and the morphologic matrix 27 different concepts where created. All of these concepts did not go further in the concept development but are described in the thesis as part of the result.

Den nuvarande konstruktionen är bl.a. tidskrävande och har en hög kostnad ur ett livscykelperspektiv. Vid undersökning av problemet framkom även brister i de riktlinjer som finns runt plomberingen. Detta gäller framförallt utbildning och användarskyldigheter. Genom att utveckla en ny plombering för utrustningar i försvaret kommer eventuell hemlig information skyddas bättre. För att systematiskt få fram bra koncept gjordes en omfattande förstudie. Förstudien innehåller utvärderingar av olika tekniker och material samt en teoridel om etiketter. I förstudien inkluderas även en behovsanalys som är baserad på intervjuer. Analysen användes sedan som hjälpmedel i de olika utvärderingarna i examensarbetet. För att underlätta framtagningen av en kravställning vid upphandling har olika metoder för verifiering och validering utvärderats. Genom konstruktionskriterielistan och den morfologiska matrisen skapades 27 koncept. Även om alla dessa koncept inte gick vidare till konceptutveckling bör de betraktas som en del av resultatet. Resultatet av arbetet redovisas i två koncept. Det första konceptet bygger på 2D-streckkod, termokromfärg och dubbelt etikettmaterial varav det understa materialet är sprött. Det andra konceptet bygger på aktiv RFID med tydliga användarriktlinjer som är skyddat med sprött material. Anledningen till att två koncept valdes som resultat beror på att båda visades vara lämpliga lösningar på problemet men även för att förberedda sig på eventuella osäkerheter runt RFID.

An audit log enables us to discover malfeasance in a system and to understand a security breach after it has happened. An audit log is meant to preserve information about important events in a system in a non-repudiable manner. Naturally, the audit log is often a target for malicious actors trying to cover the traces of an attack. The most common type of attack would be to try to remove or modify entries which contain information about some events in the system that a malicious actor does not want anyone to know about. In this thesis, the state-of-the-art research on secure logging is presented together with a design for a new logging system. The new design has superior properties in terms of both security and functionality compared to the current EJBCA implementation. The design is based on a combination of two well-cited logging schemes presented in the literature. Our design is an audit log built on a Merkle tree structure which enables efficient integrity proofs, flexible auditing schemes, efficient queries and exporting capabilities. On top of the Merkle tree structue, an FssAgg (Forward secure sequential Aggregate) MAC (Message Authentication Code) is introduced which strengthens the resistance to truncation-attacks and provides more options for auditing schemes. A proof-of-concept implementation was created and performance was measured to show that the combination of the Merkle tree log and the FssAgg MAC does not significantly reduce the performance compared to the individual schemes, while offering better security. The logging system design and the proof-of-concept implementation presented in this project will serve as a starting point for PrimeKey when developing a new audit log for EJBCA. / En granskningslogg är viktig eftersom den ger oss möjligheten att upptäcka misstänkt aktivitet i ett system. Granskningsloggen ger också möjligheten att undersöka och förstå ett säkerhetsintrång efter att det har inträffat. En attackerare som komprometterar ett system har ofta granskningsloggen som mål, eftersom de ofta vill dölja sina spår. I denna rapport presenteras en litteraturstudie av nuvarande forskning på säkra loggingsystem samt en design av ett nytt loggingsystem. Det nya loggingsystemet har bättre säkerhetsegentskaper och funktionalitet jämfört med den nuvarande implementationen i EJBCA. Designen bygger på en kombination av två välciterade forskningsartiklar. Vår design är en granskningslogg baserad på en Merkle träd-struktur som möjliggör effektiva bevis av loggens integritet, flexibel granskning, effektiv sökning och exportfunktionalitet. Förutom Merkle träd-strukturen består den nya loggen även av en FssAgg (Forward secure sequential Aggregate) MAC (Message Authentication Code) som förstärker loggens motstånd mot trunkeringsattacker och möjliggör fler sätt att granska loggen. En prototypimplementation skapades och prestandamätningar genomfördes som visar att kombinationen av Merkle träd-loggen och FssAgg MAC:en inte försämrar loggens prestanda jämfört med de individuella logglösningarna, trots att starkare säkerhet uppnås. Designen av det nya loggingsystemet samt prototypimplementationen kommer att utgöra en grund för PrimeKeys arbete med att implementera en ny audit log i EJBCA.

This thesis is concerned with identifying and describing the linguistic elements of manipulative strategies of selected political speeches from 1948 till 1957. In the first part the work is focused on the principles of political communication, further persuasion and manipulation with respect to the relationship of these terms. In the next sections we find formal and functional description language means with regard to their pragmatic semantic components, mechanisms of propaganda and political line of reasoning. Knowledge of various aspects of language allows description of specific manipulative tendencies in political speeches and their burden in terms of evident and hidden action to the addressee.

A presente obra é dedicada ao estudo dos novos mecanismos destinados a combater a morosidade do processo judicial, em especial a tutela de evidência. A pesquisa abrange a teoria da cognição, perpassando a função da verdade para o julgamento, analisando cada um dos graus de verossimilhança e a cognição de questões de direito. Em seguida, examinam-se os efeitos do tempo sobre o processo, objeto da dromologia processual. Considerando a mora como um fator de risco, são abordadas soluções teóricas para o seu adequado equacionamento, quando em confronto com o risco de erro judiciário. Um dos instrumentos para a gestão desses riscos, sempre presentes no curso processual, é a análise econômica do direito. Com vistas à formação de um prognóstico a respeito das chances de sucesso da tutela de evidência no Brasil, são explorados institutos correlatos no Direito Comparado, suas semelhanças e diferenças, bem como, sempre que possível, dados empíricos sobre os resultados obtidos nos respectivos países. Por fim, procede-se a uma análise crítica dos dispositivos do anteprojeto do novo Código de Processo Civil que versam sobre a tutela de evidência. / In a dynamic society, time is surely a kind of wealth. This is still true when it comes to litigation. Especially in civil law countries, plaintiffs are only granted what they pursue in court after a long judicial procedure that comprises the defendants hearing and the analysis of factual findings. However, it turns out that when the plaintiff proves his right at the very beginning of the trial, this time-consuming process is not only unfair to the plaintiff, but also inefficient to the Judiciary Branch as a whole. Thats mainly a result of defendants behaviors intended to protract the final resolution of the lawsuit, even when he knows that the other litigants claim is right. In those cases, preliminary injunctions not always suffice given the strict, urgency-related requirements they usually entail. In an attempt to properly address the issue, the draft of the new Brazilian Civil Procedure Code has provided for a new sort of injunction (tutela de evidência) meant to reasonably allocate the cost of time to each one of the parties. The underlining assumption is that in all judicial procedures there is a tradeoff between the risk of judgment error (due to the lack of information) and the risk of delaying justice (due to the time extent). Drawing on Law and Economics premises, this work sets forth some guidelines as to how to manage those risks fairly and efficiently.

自一九八Ο年代威權體制開始解體以來，臺灣的公民教育已然進入另一個新的蛻變階段，而其所賦予的積極意義，乃在於反映並凸顯出對以往整體公民教育的價值取向、概念論述、典範遞移、課程內涵、以及課程決定等有關問題面向所作的一種審視與反思，從而標舉一個能以「公民社會」理念作為建構總體教育目標時代的正式來臨。影響所及，值此一轉變關鍵的時刻，國人如何循由對「政治民主化、經濟自由化、社會多元化、文化本土化、以及意識主體化」等五大價值取向的認知與涵養，結合民主教育、法治教育、倫理道德教育、以及生活教育等四大核心課程內涵的深化與落實，並在致力於涵蘊「公民社會」為其學科典範遞移最高指標的同時，能進一步以強調「差異的（或多元的）公民資格觀」的概念論述及推動「公民參與」的課程決定方式，藉以充實及強化公民教育的運作機制和功能，業已成為今後公民教育責無旁貸的重要發展趨勢所在。 關鍵詞：公民教育、公民社會、價值取向、課程內涵、概念論述、典範遞移、 課程決定、公民資格、科際整合、顯著課程。 / Since the authoritarian system was began to fall apart during 1980’s in R.O.C.（Taiwan）, civic education at school has gone into an another new transformation stage and bestowed a progressive meaning too, it is so necessary as to make a review and self-examination that reflect or manifest the totality of problem dimensions about value orientation, conceptual discourse, paradigm shift, curriculum content, and curriculum decision-making for the past. Thus much to construct and mark a period of “civil society” concept of the macro educational goal is coming formally. Due to the impact, especially it happened just changing time, we need how to recognize and nourish the five value orientations of “democratization to politics, freedom to economics, plural to societies, localization to culture, and subjectivity to conscious”. Combine with the four codes of curriculum content about democracy of education, law-related education, ethics and moral education, and experiential education that must be deepened and practiced for the citizens. At the same time, it also devoted to cherish the conceptual of “civil society” to be the highest characteristic of a paradigm shift of the civic education course. Moreover, it is obliged to emphasize the “differential or plural citizenship” and push the curriculum decision-making model of the “civic participation” that its operational machinery and functions could be fulfilled and competent. In summary, there is no passing buck to these important developmental tendencies of civic education in the changing future. Key Words: civic education, civil society, value orientation, curriculum content,conceptual discourse, paradigm shift, curriculum decision-making,citizenship, interdisciplinary integration, evident curriculum.

There has existed for many years a memory enhancement technique ("memory pegs") that although having dramatic demonstrable success in some individual cases has not been generally applied in education. The emergence of constructivist epistemology has emphasised the notion that learning occurs as a result of connecting new material with previously learnt concepts. There is, therefore, the implication that effective learning requires some previous knowledge upon which to attach new concepts - and thus realisation of the importance of learning with respect to acquiring factual information as a prerequisite to learning new processes and/or skills. This issue has focussed my attention on the need to ensure that the more physiological skills of accessing 'memory', both for learning and recall, are optimised for maximum learning. Further, there are some indications that the physiological skills of memory access (storage and retrieval) may respond favourably to training and 'exercise'. This study was designed to find out whether or not a repeated 'exercise' using a simple memory enhancement technique would lead to a determinable and statistically significant increase in overall performance in a range of cognitive skills (as indicated by science and mathematics examination results), whether learning such a technique would affect a student's attitudes towards science, whether there was a relationship between the amount of time spent practicing the technique and the degree of effect, and whether the memory technique did actually improve the ability to recall lists of objects.
