Abstract (sommario):

Zusammenfassung. Das Zusammenspiel von negativem Affekt und nachfolgender Affektregulation auf das Essverhalten wurde mit 70 Versuchspersonen (Vpn) experimentell untersucht. Nach einer Imaginationsinduktion von negativem Affekt wurden die Vpn in eine positive oder in eine negative Selbstaktivierungsgruppe eingeteilt. Die Diätintention der Probanden wurde durch eine “Neujahrsvorsatz-Methode“ erfasst. Es ergaben sich folgende Interaktionen zwischen Selbstaktivierung und Diätintention: (a) Vpn mit negativer Selbstaktivierung und niedriger Diätintention aßen mehr Schokolade als Vpn in allen anderen Bedingungen. (b) Vpn mit positiver Selbstaktivierung und hoher Diätintention aßen mehr Kekse als Vpn in allen anderen Bedingungen. Die Befunde sind nicht mit der Hypothese von Tice, Bratslavsky und Baumeister (2001) vereinbar, die eine einfache Beziehung zwischen negativem Affekt und nachfolgendem Verlust der Impulskontrolle beim Essen postulierten. Es gab darüber hinaus positive Korrelationen zwischen der Menge der verzehrten Schokolade und Persönlichkeitsdispositionen mit Beziehung zu Depressivität. Implikationen der Befunde für eine Diät und die Gesundheit werden diskutiert.

Abstract (sommario):

Zusammenfassung: Sechsundsechzig Studierende nahmen an einem computer-basierten Training motivationaler Lernstrategien teil. Gegenstand des Trainings war eine Strategie, eine Lernabsicht zu entwickeln, indem man sich den persönlichen Nutzen des zu erwerbenden Wissens verdeutlicht. Die Vpn erhielten (1) kein spezifisches Training, (2) nur ein Training der motivationalen Lernstrategie oder (3) ein kombiniertes Training der Lernstrategie und darauf bezogener Selbstregulation. Nach dem Training bearbeiteten die Vpn einen Lehrtext, den sie zuvor als weniger motivierend beurteilt hatten. Es wurde erhoben, inwieweit die Vpn die Trainingsinhalte zur Anwendung brachten, welches Motivationsniveau sie bei Anwendung der gelernten Strategie erreichten und wie viel Wissen sie aus der Bearbeitung des Textes gewannen. Die Vpn des kombinierten Trainings schnitten hinsichtlich aller drei Variablen besser ab als die Vpn des Lernstrategietrainings und die Vpn ohne Training, und die Vpn des Lernstrategietrainings schnitten ebenfalls besser ab als die Vpn ohne Training. Die Ergebnisse entsprechen aktuellen Theorien des Trainings von Lernstrategien, die davon ausgehen, dass es sinnvoll ist, neben der Vermittlung von Wissen über einzelne Lernstrategien auch den zielführenden Einsatz der jeweiligen Lernstrategie zu trainieren.

Abstract (sommario):

Zusammenfassung: Die Untersuchung galt der Frage, welche Bedeutung ausschließlich den Körper- und Gliederbewegungen des Menschen in face-to-face Situationen bei der Eigenschaftsattribution zukommt. Hierzu wurde das Verfahren der Skriptanimation eingesetzt, womit sich die entsprechenden Bewegungen von anderen normalerweise zur Verfügung stehenden Informationen isolieren und auf eine Computerpuppe übertragen lässt. Insgesamt 153 Versuchspersonen nahmen an drei Versuchsreihen teil und beurteilten nacheinander 12 verschiedene Fernsehakteure: 55 Vpn beurteilten die Originalaufzeichnung der Akteure; 33 Vpn beurteilten die originalgetreu reanimierten Körper- und Gliederbewegungen der Darsteller; 65 Vpn beurteilten die im Bewegungsablauf modifizierten Animationen. Als Beurteilungsinstrument wurden Ratingskalen eingesetzt. Die Ergebnisse veranschaulichen, dass die Eliminierung bzw. Konstanthaltung aller Begleit- und Kontextinformationen keinen systematischen Einfluss auf die Eigenschaftsattributionen ausübte. Andererseits genügten bereits kleine Modifikationen im Bewegungsablauf der Kopf- und Rumpfbewegungen, damit sich das Bild, das sich die Vpn von den dargestellten Personen machten, auf nahezu allen Urteilsskalen entweder verbesserte oder verschlechterte. Die Ergebnisse werden mit Erkenntnissen aus Multikanalanalysen nonverbalen Verhaltens in Zusammenhang gebracht.

Abstract (sommario):

Epizootic hemorrhagic disease virus (EHDV) is a Culicoides transmitted orbivirus that causes haemorrhagic disease in wild and domestic ruminants. A collection of 44 EHDV isolated from 2008 to 2012 was fully sequenced and analysed phylogenetically. Serotype 2 viruses were the dominant serotype all years except 2012 when serotype 6 viruses represented 63 % of the isolates. High genetic similarity (>94 % identity) between serotype 1 and 2 virus VP1, VP3, VP4, VP6, NS1, NS2 and NS3 segments prevented identification of reassortment events for these segments. Additionally, there was little genetic diversity (>96 % identity) within serotypes for VP2, VP5 and VP7. Preferential reassortment within the homologous serotype was observed for VP2, VP5 and VP7 segments for type 1 and type 2 viruses. In contrast, type 6 viruses were all reassortants containing VP2 and VP5 derived from an exotic type 6 with the remaining segments most similar to type 2 viruses. These results suggest that reassortment between type 1 and type 2 viruses requires conservation of the VP2, VP5 and VP7 segment constellation while type 6 viruses only require VP2 and VP5 and are restricted to type 2-lineage VP7. As type 6 VP2 and VP5 segments were exclusively identified in viruses with type 2-derived VP7, these results suggest functional complementation between type 2 and type 6 VP7 proteins.

Abstract: A VPN is an essential tool for securing your personal data and protecting your privacy online. We’ve put together the ultimate guide to VPNs to show you what a VPN does, how VPNs work, and how they protect you. Learn how to choose the right VPN, or secure your privacy right now by downloading our own powerful and lightning-fast VPN app. A VPN works by using encryption protocols to funnel all your internet traffic through an encrypted tunnel a virtual private network between your computer and a remote VPN server. This hides your IP address and secures your data, preventing others from intercepting it. Without a VPN, all your internet traffic is potentially exposed to your internet service provider (ISP), the government, advertisers, or other people on your network. That’s why VPN connections boost your privacy and security online. VPN is virtual because it’s created digitally there isn’t a physical cable that reaches from your device directly to the VPN server.

Abstract (sommario):

The ever-increasing internet is an ISP challenge for the future of the expected global computer network traffic and QoS needs. To maintain competitive ISPs in Indonesia with the development of internet usage, the demand for QoS must be increased. MPLS VPN networks combine layer 2 switching technology with layer 3 routing technology. MPLS VPN networks have emerged as technologies that meet VPN requirements such as private IP, and the ability to support overlapping addresses in resolving speed and QoS problems. The method used is experimental research. From the measurement results obtained by VPN and MPLS VPN network delay has a very good delay value. For throughput on VPN networks have medium quality and MPLS VPN networks have good quality. And for the packet loss value for both types of networks is 0%. This shows that MPLS VPN network throughput has better QoS while for delay and packet loss on VPN and MPLS VPN networks have the same quality value.

Abstract (sommario):

Abstract The rapid growth of e-business in past few years has improved companies efficiency and revenue growth. E-business applications such as e-commerce, remote access has enabled companies to manage processes, lower operating costs and increased customer satisfaction. Also the need rises for the scalable networks that accommodate voice, video, and data traffic. With the increased dependability of networks the security issues are raised and networks become more and more vulnerable to different types of security threats. To overcome security issues different security technologies are in action by vendors and technologists. Also for the survival of many businesses to allow open access to network resources, today’s networks are designed with the requirement of availability to the Internet and public networks, therefore, information confidentiality is the major issue in these networks to ensure that the network resources and user data are as secure as possible. With the requirement of network security, concept of Virtual private network was established. A Virtual Private Network (VPN) can be defined as a network in which connectivity between multiple customers’ sites is deployed on a shared network with the same security as a private network. Different VPN technologies and protocols architectures are available in market among are MPLS VPN architecture, IPSec VPN architecture, and SSL VPN architecture. Like With the introduction of Multiprotocol Label Switching (MPLS), which combines the benefits of Layer 2 switching and Layer 3 routing, it became possible to construct a technology that combines the benefits of an overlay VPN with the benefits of peer-to-peer VPN implementation in which routing is simple. MPLS/VPN is a new and simple technology, which provides simpler to routing and also makes number of topologies easy to implement which are otherwise difficult to implement. All architectures have benefits and drawbacks, also each of them can be implemented separately or in combination of other according to customer security requirement and performance of the network.

Abstract (sommario):

Dagens företag vill ge anställda möjlighet att jobba hemifrån eller på resande fot. En vanlig lösning för att möjliggöra detta är virtual private network (VPN). VPN ger en användare tillgång till interna resurser på företaget från ett externt nät, exempelvis via Internet. Detta gör att användare kan komma åt de interna resurserna på ett säkert sätt. Vilken VPN-teknik är då att föredra för att få en så snabb, säker och pålitlig anslutning som möjligt? Detta examensarbete tar upp olika VPN-tekniker. Vi beskriver vanliga VPN-protokoll som L2TP, IPSec och PPTP. Hur användare autentiseras på ett säkert och smidigt sätt samt metoder att göra sin VPN-anslutning säker. Vi redovisar också den lösning vi har implementerat hos Confidence, för vilka arbetet utfördes. Problemen med att använda de produkter som redan fanns på företaget beskrivs. Förslag på lösningar ges för att lösa dessa problem i framtida arbeten.
Companies of today want to give their employees the opportunity to work from home or while they travel. A common solution to accomplish this is to implement a VPN over top of the existing network. Using VPN gives the employees access to the company’s local area network from outside, via the internet. The VPN provides a secure channel for these employees to connect to the local services attached to the company’s network that they need to reach. Which VPN technology is most suitable to deliver a secure, fast, and reliable connection to theses employees? In this thesis examines we are taking a closer look at different VPN solutions. We describe different VPN-protocols like L2TP, IPSec and PPTP. How to authenticate users in a secure and flexible way and also methods used to make the VPN-connection secure. Lastly we will show the solution we have implemented at the company Confidence, for whom we made the solution. The difficulties in using existing products with the company’s infrastructure are described. Suggestions are offered for future work to address these problems.

Abstract (sommario):

Syftet med denna undersökning är att ta reda på vilken mjukvarubaserad fjärranslutningslösning som passar för ett mindre företag, då de har mindre ekonomiska tillgångar än ett större företag behöver de vara mer noggranna med sina produktval. Arbetet är utfört med litteraturstudier och en enkätundersökning till ett tiotal mindre företag, samt en laborationsmiljö där tester av de olika fjärranslutningslösningarnas egenskaper har utförts.

Område valdes då ämnet fjärranslutning knappt behandlads under utbildningstiden, och fördjupar sig därför inom området.

Resultatet visar vad mindre företag anser vara de viktigaste egenskaperna med en fjärranslutningslösning. Även de värden som uppkom vid tester i laborationsmiljön kommer att presenteras i resultatet. De samlade resultaten kommer sedan visa på vilken mjukvarubaserad lösning som passar bäst för ett mindre företag.

The purpose of this survey is to figure out which software based remote access solution that fits a smaller company, hence they have less economy assets than a larger company they need to be more thorough with their products of choice. The work is performed with literature studies and a survey of a dozen smaller companies, and also a laboratory environment where properties of the different remote access solutions are performed.

This area was chosen because the subject of remote access scarcely was treated during our education, and become engrossed in this area.

The result shows what the companies consider to be the most important properties with a remote access and also the products results from the tests. Also the values that occurred during testing in a laboratory environment will be presented in the results. The combined results will then show which software-based solution that is best suited for a small company.

Abstract (sommario):

Denna rapport har i syfte att öka förståelsen om hur man kan öka säkerheten på ett företag som använder sig av mobila klienter. Att arbeta på distans blir allt vanligare, och med de så ställs allt högre krav på tekniken som tillhandahåller möjligheterna för detta. När ny teknik utvecklas kommer ofta säkerheten i andra hand, det man fokuserar på är funktionaliteten. Frågorna man då ställer sig och vilket läsaren kommer skaffa sig mer kunskap om under rapprotens gång är: Hur skall en klient kunna hållas uppdaterad när den är utanför företagets väggar? Hur skall kommunikation kunna ske med företaget på ett enkelt sätt, samtidigt som det också ska vara säkert? Det kommer visa sig att administratören inte är den pusselbiten i säkerheten på ett företag. Företaget kan ha en mycket gedigen och bra säkerhetspolicy, men med en användare som handskas vårdslöst med sina användaruppgifter så spelar inte denna någon roll.
The aim of this paper is to give new information on how to increase the security at a company that uses mobile clients. Tele-work and E-work is becoming more common, therefore, the technology used must have the utmost reliability. In general, when technology is being developed, the primary focus is on the functionality of the product and less on the aspect of security. Key questions that will be raised and answered are: How should a mobile client be kept up to date with a company’s current software updates? How can this type of communication be achieved in a simple and secure way? Furthermore, the paper will illustrate that the success rate of all levels of security in a company does not depend solely on the administrator. Without the proper use of the security policy by the user, its reliability decreases.

Abstract (sommario):

VPNs are being hailed as the solution for several situations involved in the Internet these days. Firewalls have seen a decade of evolution and sophistication to deal with specific problems. However, we are also seeing the proliferation of VPN configurations on otherwise secure networks based on firewalls. This paper discusses the security problems incurred by the adoption of VPN gateways in standard firewalls. It also suggests more secure topology solutions for the standard VPN uses, as well as for the remote access client. We also propose an implementation based on freely available software that satisfies the security issues brought about by this paper.

Abstract (sommario):

Introdução: O presente estudo tem por objetivo principal determinar a acurácia dos achados colposcópicos no diagnóstico das lesões intraepiteliais de colo uterino. Como objetivos secundários: determinar a acurácia da citologia oncótica no diagnóstico das lesões intraepiteliais de colo uterino; determinar a sensibilidade (S), a especificidade (E), o valor preditivo positivo (VPP) e o valor preditivo negativo (VPN) da citologia e da colposcopia em relação ao exame histopatológico. Métodos: Trata-se de um estudo analítico, retrospectivo, transversal e observacional, baseado na análise de prontuários de pacientes que foram encaminhadas da rede básica de saúde ao ambulatório de patologia do trato genital inferior e colposcopia de centro terciário por alteração no exame citopatológico convencional, no período de fevereiro de 2011 a agosto de 2018. As citopatologias foram classificadas pelo Sistema Bethesda, 2001. Com base nos resultados de citologia, colposcopia e histopatologia cirúrgica (cone/ cirurgia de alta frequência - CAF), foram calculados S, E, VPP e VPN, utilizando a histopatologia cirúrgica como padrão ouro. Resultados: Os valores obtidos para a citologia foram S=70,8%; E=47,8%; VPP=84,1%; e VPN=29,4%. Os resultados da colposcopia demonstraram S=79,3%; E=46,7%; VPP=85,4%; e VPN=36,4%. A acurácia, portanto, foi 66,1% da citologia e 72,7% da colposcopia. Conclusão: Apesar da pouca diferença entre as acurácias, demonstrou-se a importância da realização de ambos os exames na triagem para evitar o excesso ou a falta de diagnóstico e tratamento. Observou-se que tanto a citologia quanto a colposcopia são mais eficazes na identificação de lesões de alto grau em relação às de baixo grau, gerando um número importante de falsos negativos, que foram detectados por causa da complementação entre os exames de citologia e colposcopia.
