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):

Virtual Private Network (VPN) is a private network that uses public network to tunnel the connection from the users’ end to the VPN server. VPN allows users to create a secure connection to another network over the public Internet. VPNs can be used to shield users’ browsing activity and encrypts data transmitted over the network to prevent sniffing attack. Nowadays, users can either pay a premium price for a good VPN service or risk their privacy using free browser-based VPN. Thus, SafeSearch is developed to address these issues in mind. With SafeSearch, users will not need to fork out a lot of money for premium VPN subscription services or expose themselves to targeted advertising when utilising free browser-based VPN. In this study, open VPN protocol was used to create the VPN server on a microcomputer called Raspberry Pi. The software used was mostly open-source except for the VPN client. Obfuscation technique was used to hide VPN traffic by disguising it as just another normal Internet traffic against Deep Packet Inspection when passing through firewall. After the VPN server was established, tests were carried out to evaluate the functionality and reliability of the VPN server in “real-world” environment. The tests conducted were network restriction penetration assessment, network performance and user acceptance test. Penetration assessment result showed that SafeSearch is capable of bypassing web filtering and deep packet inspection. Network performance during SafeSearch connection has slight latency and bandwidth decline, although it is not overly affected. The outcome of the user acceptance test was positive as the majority of participants of the study were confident that SafeSearch can secure their connection and protect their privacy when browsing the web. To conclude, both objectives of this project were fully achieved and the scope of study was followed thoroughly.

Abstract (sommario):

Banna virus (BAV) is the type species of the genus Seadornavirus within the family Reoviridae. The Chinese BAV isolate (BAV-Ch), which causes encephalitis in humans, was shown to have a structural organization and particle morphology reminiscent of that of rotaviruses, with fibre proteins projecting from the surface of the particle. Intact BAV-Ch virus particles contain seven structural proteins, two of which (VP4 and VP9) form the outer coat. The inner (core) particles contain five additional proteins (VP1, VP2, VP3, VP8 and VP10) and are ‘non-turreted’, with a relatively smooth surface appearance. VP2 is the ‘T=2’ protein that forms the innermost ‘subcore’ layer, whilst VP8 is the ‘T=13’ protein forming the core-surface layer. Sequence comparisons indicate that BAV VP9 and VP10 are equivalent to the VP8* and VP5* domains, respectively, of rotavirus outer-coat protein VP4 (GenBank accession no. P12976). VP9 has also been shown to be responsible for virus attachment to the host-cell surface and may be involved in internalization. These similarities reveal a previously unreported genetic link between the genera Rotavirus and Seadornavirus, although the expression of BAV VP9 and VP10 from two separate genome segments, rather than by the proteolytic cleavage of a single gene product (as seen in rotavirus VP4), suggests a significant evolutionary jump between the members of these two genera.

Abstract (sommario):

This paper proposes a design for a network connected over public networks using Virtual Private Network (VPN) technique. The network consists of five sites; center server and four customer service sites, each site consists of a number of LANs depending on the user services requirements. This work aims to measure the effect of VPN on the performance of a network. Four approaches are implements: Network design without using VPN, network design using VPN with centralized servers, network design using VPN with distributed servers, and network design using server load balance.The OPNET and BOSON simulation results show higher response time for packet transmission due to effect of VPN tunneling. The concurrent activation of application execution is used as a solution to the delay problem of the initial timing period while the application proceeds. The results dealing with QoS are E-mail, FTP, voice services traffic and IP traffic dropped. The VPN Tunnels is in the range of (0.01 to 0.02) sec.; along with this simulator there are four VPN tunnels in the network. Also, a special server’s load balance is used to manage distribution of the server processing load across all other network servers to achieve the best response

Abstract (sommario):

Bluetongue virus (BTV) is the type species os the genus orbivirus in the family Reoviridae. The virus has a fibrillar outer coat containing two major structural proteins VP2 and VP5 which surround an icosahedral core. The core contains two major proteins VP3 and VP7 and three minor proteins VP1, VP4 and VP6. Recent evidence has indicated that the core comprises a neucleoprotein center which is surrounded by two protein layers; VP7, a major constituent of capsomeres comprises the outer and VP3 the inner layer of the core . Antibodies to VP7 are currently used in enzyme-linked immunosorbant assays and immuno-electron microscopical (JEM) tests for the detection of BTV. The tests involve the antibody recognition of VP7 on virus particles. In an attempt to understand how complete viruses can interact with antibodies to VP7 various antibody types and methodologies were utilized to determine the physical accessibility of the core to the external environment.

Abstract (sommario):

Encryption Protocols e.g., HTTPS is utilized to secure the traffic between servers and clients for YouTube and other video streaming services, and to further secure the communication, VPNs are used. However, these protocols are not sufficient to hide the identity of the videos from someone who can sniff the network traffic. The present work explores the methodologies and features to identify the videos in a VPN and non-VPN network traffic. To identify such videos, a side-channel attack using a Sequential Convolution Neural Network is proposed. The results demonstrate that a sequence of bytes per second from even one-minute sniffing of network traffic is sufficient to predict the video with high accuracy. The accuracy is increased to 90% accuracy in the non-VPN, 66% accuracy in the VPN, and 77% in the mixed VPN and non-VPN traffic, for models with two-minute sniffing.

Abstract The need for a ship monitoring system based on Automatic Identification System (AIS) has been developed and provides many broad benefits for the maritime world in Indonesia. The system can become an early warning system (EWS) for ship operators, port operators, and even ship owners for tracking a movement of their ships. By internet connection based Virtual Private Network (VPN) can connect several remote base stations (RBS), VPN technology can integrate many RBS from several remote places into one AIS monitoring system. VPN-based internet connection is used to guarantee a secure network, private internet connection, and can access a network remotely. VPN technology encrypts data exchange even before data transmission reaches the public network. Connecting to the internet using a VPN connection is like accessing the internet using a special tunnel, not in the main internet network. Thus the use of a VPN-based internet connection in the AIS monitoring system can ensure the security of data transmission from RBS to the AIS monitoring server.

Abstract (sommario):

Data exchange communication has developed, which leads to centralized communication, and to achieve this communication requires a type of data communication whose data is accommodated on the server and can be accessed by clients, such as at organization. As a company engaged in education, the development of centralized data communication by utilizing the intranet network has been formed. The use of an intranet network allows data communication that is vulnerable to wiretapping. To fix this using a VPN network. L2TP and IPsec VPNs have different performances, especially in the level of security provided. In this study, an analysis of the L2TP and IPsec VPN network performance was carried out on the SMB Server on the Ubuntu server and the Mikrotik router for its VPN configuration. In this study, the L2TP and IPsec VPN was designed by configuring the Mikrotik RB 450G router and the SMB Server configuration using Command Line Interface on Ubuntu 18.04 server. For security analysis, use hacking methods to get VPN Server login data and sniffing methods to get SMB Server login data and SMB data. For performance analysis using parameters of delay, throughput, and packet loss. Wireshark is software for checking by capturing each packet of data from an interface. The research objective to be achieved is to design a VPN technology based on L2TP & IPSec, to be able to determine the resulting performance after implementing a VPN based on L2TP & Ip Sec. The result is that VPN can connect from HO to branch one and branch two or connect from public connection to local connection. The Ubuntu server used is also running well, so it helps the VPN process properly.

Abstract (sommario):

Rotaviruses (RVs) are a major etiological agent of acute viral gastroenteritis in humans and young animals, with rotavirus B (RVB) often detected in suckling and weaned pigs. Group A rotavirus classification is currently based on the two outer capsid proteins, VP7 and VP4, and the middle layer protein, VP6. Using RVB strains generated in this study and reference sequences from GenBank, pairwise identity frequency graphs and phylogenetic trees were constructed for the eleven gene segments of RVB to estimate the nucleotide identity cutoff values for different genotypes and determine the genotype diversity per gene segment. Phylogenetic analysis of VP7, VP4, VP6, VP1–VP3, and NSP1–NSP5 identified 26G, 5P, 13I, 5R, 5C, 5M, 8A, 10N, 6T, 4E, and 7H genotypes, respectively. The analysis supports the previously proposed cutoff values for the VP7, VP6, NSP1, and NSP3 gene segments (80%, 81%, 76% and 78%, respectively) and suggests new cutoff values for the VP4, VP1, VP2, VP3, NSP2, NSP4, and NSP5 (80%, 78%, 79%, 77% 83%, 76%, and 79%, respectively). Reassortment events were detected between the porcine RVB strains from our study. This research describes the genome constellations for the complete genome of Group B rotaviruses in different host species.

Abstract (sommario):

The VPN technology is used to connect client devices securely over unsecured public networks. The Connection handover and Dead Peer Detection (DPD) are the most challenging and important tasks in VPN. In this present article, a solution for connection handover is proposed which covers the pre-authentication with new credentials for a mobile device prior to connection handover. In VPN, a case where such connection handover is failed due to incomplete connection handover or several unusual events which make a VPN client to become offline or dead. To address DPD issues a solution is proposed which includes a Keep Alive Timer (KAT) server at the VPN server side. This proposed solution for DPD is far better than an already existing solution that uses a DNS server for DPD since the DNS server faces several attacks consistently. Thus, the proposed solution for DPD is more secure against such vulnerable attacks.
