Juknienė J. The peculiarities of self-assessment, sense of coherence and self-awareness of the 1 st – 2 nd formers of different advance. The final work of the Master of Psychology / the scientific supervisor – Doc. Dr. M. Pileckaitė – Markovienė; Vilnius Pedagogical University; the department of Psychology Didactics. – Vilnius, 2005. - 92 p. In this master work there is analyzed the self-assessment, sense of coherence and self-awareness of the students of different advance. In junior school age the making human’s disharmony shows through, which later causes emotional, behavior and learning problems, and social disadaptation. The aim of research – to analyze the peculiarities of personality of the 1 st – 2 nd formers of different advance in aspects of self-evaluation, sense of coherence and self-identification. The goals of research are: 1) to compare the self-assessment and sense of coherence of the students of high, average and low advance; 2) to evaluate students’ possibility to identify their own present, past and future status of age and sex, considering students’ advance; 3) to compare students’ understanding about the choice of attractive and unattractive image. There were used the following methods of research: analysis of nonfiction, conversation, questionnaires for children. Two hundred 1 st – 2 nd formers at the age of 7 – 8 participated in this research. The information about those children’ learning results was received from their teachers. According to this...

The ever-increasing technological advances in embedded systems engineering, together with the proliferation of small-size sensor design and deployment, have enabled mobile devices (e.g., smartphones) to recognize daily occurring human based actions, activities and interactions. Therefore, inferring a vast variety of mobile device user based activities from a very diverse context obtained by a series of sensory observations has drawn much interest in the research area of ubiquitous sensing. The existence and awareness of the context provides the capability of being conscious of physical environments or situations around mobile device users, and this allows network services to respond proactively and intelligently based on such awareness. Hence, with the evolution of smartphones, software developers are empowered to create context aware applications for recognizing human-centric or community based innovative social and cognitive activities in any situation and from anywhere. This leads to the exciting vision of forming a society of ``Internet of Things" which facilitates applications to encourage users to collect, analyze and share local sensory knowledge in the purpose for a large scale community use by creating a smart network which is capable of making autonomous logical decisions to actuate environmental objects. More significantly, it is believed that introducing the intelligence and situational awareness into recognition process of human-centric event patterns could give a better understanding of human behaviors, and it also could give a chance for proactively assisting individuals in order to enhance the quality of lives. Mobile devices supporting emerging computationally pervasive applications will constitute a significant part of future mobile technologies by providing highly proactive services requiring continuous monitoring of user related contexts. However, the middleware services provided in mobile devices have limited resources in terms of power, memory and bandwidth as compared to the capabilities of PCs and servers. Above all, power concerns are major restrictions standing up to implementation of context-aware applications. These requirements unfortunately shorten device battery lifetimes due to high energy consumption caused by both sensor and processor operations. Specifically, continuously capturing user context through sensors imposes heavy workloads in hardware and computations, and hence drains the battery power rapidly. Therefore, mobile device batteries do not last a long time while operating sensor(s) constantly. In addition to that, the growing deployment of sensor technologies in mobile devices and innumerable software applications utilizing sensors have led to the creation of a layered system architecture (i.e., context aware middleware) so that the desired architecture can not only offer a wide range of user-specific services, but also respond effectively towards diversity in sensor utilization, large sensory data acquisitions, ever-increasing application requirements, pervasive context processing software libraries, mobile device based constraints and so on. Due to the ubiquity of these computing devices in a dynamic environment where the sensor network topologies actively change, it yields applications to behave opportunistically and adaptively without a priori assumptions in response to the availability of diverse resources in the physical world as well as in response to scalability, modularity, extensibility and interoperability among heterogeneous physical hardware. In this sense, this dissertation aims at proposing novel solutions to enhance the existing tradeoffs in mobile sensing between accuracy and power consumption while context is being inferred under the intrinsic constraints of mobile devices and around the emerging concepts in context-aware middleware framework.

FundaÃÃo Cearense de Apoio ao Desenvolvimento Cientifico e TecnolÃgico / Este trabalho parte da constataÃÃo GÃis de que, dentre os diversos fatores que atuam no processo de conscientizaÃÃo, encontra-se o modo de participar de atividades comunitÃrias. Pergunta-se, a partir dessa afirmaÃÃo, de que modo a forma de participar interfere nesse processo, definido aqui a partir de Paulo Freire. Tem como objetivo, portanto, discutir de que maneira o modo de participar de atividades comunitÃrias influencia no processo de conscientizaÃÃo. Para tanto, inicialmente, estabelece uma discussÃo a respeito das diferentes formas de participar e os fatores que atuam no fenÃmeno da participaÃÃo. Em seguida, a partir da Psicologia ComunitÃria, da EducaÃÃo Libertadora e da Teoria HistÃrico-Cultural da Mente, discorre acerca das implicaÃÃes psÃquicas das interaÃÃes humanas, discutindo os conceitos de: comunidade, atividade comunitÃria, consciÃncia e conscientizaÃÃo. Utilizou-se uma abordagem qualitativa, com enfoque etnogrÃfico, entrevistando-se uma pessoa que faz parte do Projeto de EducaÃÃo em CÃlulas Cooperativas (PRECE), por meio de entrevista semi-estruturada, com foco na histÃria de vida do entrevistado. Realizaram-se registros da entrevista e diÃrio de campo, de um total de sete visitas. A partir de entÃo, foi possÃvel analisar o modo de participar do sujeito da pesquisa e realizar uma anÃlise temÃtica de sua entrevista. Como resultado, pÃde-se verificar que um modo de participaÃÃo mais ativo e cooperativo propicia condiÃÃes para que o sujeito fortaleÃa suas interaÃÃes com a realidade pela apropriaÃÃo e significaÃÃo dessa maneira de se relacionar, por parte do indivÃduo. / This work is based on GÃisâs verification that, among the many factors that act on the awereness process, the way to participate of communiÂtarian activity is one of them. It is asked from the statement of that the way to participate influences this process, defined here for Paulo Freireâs theory. It has as objective, therefore, discuss how the way to participate of communiÂtarian activity influences on the the awereness process. For in such a way, initially, it establishes a quarrel regarding the different forms to participate and the factors that act in the phenomenon of the participation. After that, from Communitarian Psychology, of the Liberating Education and the Historical-Cultural Theory of the Mind, it discourses concerning the psychic implications of the interactions human beings, arguing the concepts of: community, communitarian activity, conscience and awareness. A qualitative boarding was used, with ethnographic approach, interviewing a person who is part of Projeto de EducaÃÃo em CÃlulas Cooperativas (PRECE), through the half-structuralized interview, with focus in the history of life of the interviewed one. Registers of the daily interview and of field, a total of seven visits had been become fullfilled. From now on, it was possible to analyze the way to participate of the citizen of the research and to carry through a thematic analysis of its interview. As result, we could verify that way of a more active and cooperative participation propitiates conditions so that the citizen in this way fortifies its interactions with the reality through the appropriation and significaÃÃo of if relating, on the part of the individual.

This theses concerns with social engineering and defense against it. Social engineering attacks represents significant threat for organizations and their information systems, especially because they target weakest link in information systems security, its users. That way attacker can easily bypass even highly sophisticated security system. This theses tries to deal with question, how to effectively secure human factor of information system.

In the realm of autonomous underwater exploration and surveillance, the capability of Autonomous Underwater Vehicles (AUV) to make informed decisions in dynamic and often unpredictable environments is crucial. This thesis investigates how a software architecture can be designed and implemented for autonomous decision making on the remotely operated vehicle BlueROV2. Using raw sensor data and external information inputs, situational awareness (SA) is achieved. This is used as a basis for real-time decision making during a search mission that is set up. The thesis aims for the AUV to base its actions on the SA. This is demonstrated through a search scenario in which the AUV is assigned the task of locating a number of targets in an underwater environment. To solve the task, the AUV is able to use two different methods to solve the same problem. Either by using the sonar to locate points of interest and subsequently investigate those locations or systematically traversing the entire search area using a camera to search. The trade-off between thoroughness and time consumption makes the methods favourable in different situations. Four modules are developed and implemented in the architecture. A sensor module that collects the data, an SA module that refines the data, a decision module that handles decisions in two layers and an execution module that performs the actions. A modular architecture is developed, which enables the AUV to decide which search method to prioritise and interpret the surroundings to differentiate between targets and decoy objects. Dynamic decision-making is accomplished by changing search strategies during missions and returning when all targets are found. The targets are located with a precision high enough to make out individual targets and keep track of previously seen targets. The research contributes to the field of autonomous decision making by laying a foundation for adding more sophisticated algorithms for future problem-solving. The implemented algorithms are placeholders to showcase the capabilities developed, and the architecture is modular to enable future changes and extensions of the work.

Die vorliegende Arbeit untersucht die Anwendung des Groupware Systems cAR/PE!, das auf der Mixed Reality Technologie basiert. cAR/PE! wurde im Forschungszentrum Ulm der Daimler- Chrysler AG speziell für Ingenieure entwickelt, die in verteilten Gruppen zusammenarbeiten. Im Rahmen zweier Studien fand eine Testung der Software in verschiedenen Werken der DaimlerChrysler AG statt. Interviews mit verteilt arbeitenden Ingenieuren als auch deren Beobachtung bei Projektmeetings bildeten die Grundlage für die Konzeption beider Studien. In der ersten Studie wurde der erste Prototyp von cAR/PE! untersucht. Hierbei zeigte sich kein signifikanter Unterschied in der Lösungsgüte von Gruppen, die eine Aufgabe mit geringer Komplexität in cAR/PE! oder in einem realen Meeting zu bearbeiten hatten. Bei der Bearbeitung der komplexen Konstruktionsaufgabe schnitten Gruppen in realen Meetings besser als cAR/PE!-Meeting Gruppen ab. Auf Grundlage der Ergebnisse dieser ersten Studie wurde cAR/PE! Zu cAR/PE!2 weiterentwickelt und in einer zweiten Studie wiederum evaluiert. Die zweite Studie bestand aus zwei Forschungsbedingungen, in denen die Gruppen die komplexe Konstruktionsaufgabe amphibious car bearbeiten mussten. Unter der ersten Forschungsbedingung schnitten reale Meetings2 Gruppen weiterhin signifikant besser als cAR/PE!2-Gruppen ab. Der Problemlöseprozess dieser Gruppen war vergleichbar und somit nicht mehr - wie in der ersten Studie - strukturell unterschiedlich. Die Unterschiede in der Lösungsgüte lassen sich vielmehr auf die stärkere softwarebedingte Beeinträchtigung durch die Nutzung von cAR/PE!2 zurückführen. Unter der zweiten Forschungsbedingung wurde der Einfluss der Arbeitsumgebung auf die Qualität der Gruppenarbeit untersucht. Die Arbeitsumgebung weist einen direkten, allerdings nicht signifikanten Einfluss auf den Problemlöseprozess der Gruppen auf. Somit konnte abgeleitet werden, dass die Arbeitsumgebung für eine erfolgreiche Kommunikation lediglich relevante Informationen für die Problemlösung und die Bestimmung des Sprecherortes beinhalten sollte. Auf der theoretischen Ebene konnte das mit task awareness erweiterte Rahmenmodell von Vertegaal et al. (1997) untermauert werden. Außerdem erwies sich das Model for the elements of distributed group work als sehr geeignet zur strukturierten Darstellung von Unterschieden in Gruppenarbeit. Auf der praktischen Ebene wurde cAR/PE! durch die Ergebnisse beider Studien weiterentwickelt und etablierte sich als Groupware System in den Werken bei der Daimler-Chrysler AG zwischen Sindelfingen und Bremen. / The aim of this thesis is to examine the use of the groupware system cAR/PE!, which is based on Mixed Reality technology. cAR/PE! was developed at the DaimlerChrylser Research Center in Ulm dedicated to distributed engineering group work and subsequently tested in two studies at various plants of DaimlerChrysler AG. Interviews and observations of engineer meetings in distributed project groups provided the basis for the conception of the two empirical studies. In the first study the first cAR/PE! prototype was tested. The study confirmed that less complex tasks could be solved equally well in both a conventional meeting room and in cAR/PE! Meetings. However, when solving a complex task, the conventional meeting was more favorable than cAR/PE!. These results were exploited for further developments of cAR/PE! resulting in cAR/PE!2. In the second study, the modifications were evaluated under two conditions to solve the complex design task amphibious car. Under the first condition, groups were still better at solving a complex task under the conventional meeting2 condition compared with cAR/PE!2, even the problem-solving processes were comparable and no longer structurally different than in the first study. The differences in the group results were caused by the software when using cAR/PE!2. Under the second condition, the influence of the meeting workspace was tested; this had a direct influence on the problem-solving processes of the groups, but the result was not significant. However, from this outcome it was deduced that only the relevant information for the tasks and the physical placement of the speaker leads to a successful conversation. On the theoretical level, the enhancement of the framework developed by Vertegaal et al. (1997) introducing the concept of task awareness and the appropriateness of the Model for the elements of distributed group work were confirmed. On the practical level, cAR/PE!2 was improved based on the results of both studies, then implemented and established as a permanent running groupware system between DaimlerChrysler´s plants in Sindelfingen and Bremen.
