Adaptable Java Agents (AJA) — a Tool for Programming o f Multi-Agent Systems / Adaptabilni java agenti – alat za programiranje multi-agentskih sistema

Bađonski Mihal 07 April 2004 (has links)
<p>The main goal of this thesis is the creation o f the tool agent-oriented programming tool AJA. AJA is the acronym for Adaptable Java Agents. AJA consists o f two programming languages:<br />- A higher-level language used for the description of the main agent parts. This language is called HADL, which is the acronym for Higher Agent Definition Language.<br />- A lower-level language used for the programming o f the agent parts defined in HADL. This language is called Java+. It is actually Java enriched with the constructs for accessing higher-level agent parts defined in HADL.<br />A translator from AJA to Java is implemented in the practical part o f the thesis. AJA agents have the following features: - Agent communicates with other agents using a construct called negotiation. The messages sent can be encrypted or digitally signed in order to ensure the security of the system. - Agent possesses adaptable&nbsp; parameters and neural nets that adapt themselves when the environment changes.<br />- Agent has reflexes, which are the reactive component o f the agent architecture.<br />- Agent can perform its actions parallel. Actions execution is synchronized.<br />- Agent is accessible via Internet, because it acts as a simple HTTP server. People can use this way to communicate with an agent.<br />- Agent has Java Swing based graphical user interface. Its owner uses this interface to communicate with the agent.<br />- Because o f the fact that Java-i- language extends Java, it is possible to use all useful Java features in the implementation o f AJA agents (e.g. JDBC for the database access). The thesis also presents an original approach of integrating artificial intelligence techniques, such as neural nets, with a programming language. Having the artificial intelligence components as a part of the programming language runtime environment makes their use straightforward. A programmer uses the language constructs that are implemented using the artificial intelligence<br />without the need for understanding their background and theory.<br />The thesis contains eight chapters and three appendixes. In the first chapter, an overview of agents and multi-agent systems is given. The second chapter surveys existing agent-oriented programming languages and tools. The third chapter introduces AJA and describes the architecture of AJA agents. The syntax and semantics o f AJA languages HADL and Java+ is described in the fourth chapter. The fifth chapter presents adaptable AJA constructs in more details. To demonstrate and test the created tool, a case-study multi-agent system has been implemented in AJA. There are four personal digital assistant agents in the system. The sixth chapter describes the example agents and positively evaluates the tool. In the seventh chapter the related work and tools are analyzed and compared to AJA. The last chapter concludes the thesis. The first appendix describes the implementation details of the AJA to Java translator. The second appendix is a guide for the installation and usage of the implemented AJA to Java translator. Finally, the third<br />appendix describes step by step how to translate, compile, run, and use the example agents. The thesis contains many references, which include almost all the most important and the most actual papers in the field. The reference list can be found at the end o f the thesis.</p> / <p>Glavni doprinos doktorske teze je napravljeni alat za programiranje agenata AJA . AJA - Adaptabilni Java Agenti je jezički alat za programsku implementaciju agenata Sastoji se od dva programska jezika:<br />- Jezik vi&scaron;eg nivoa kojim se opisuju glavne kom ponente agenta. Ovaj jezik se naziva HADL - Higher Agent Definition Language.<br />- Jezik nižeg nivoa koji služi za implementaciju pojedinih komponenti agenta specificiranih HADL jezikom . Ovaj jezik se najava Java+, jer je on zapravo programski jezik Java obogaćen konstrukcijama pomoću kojih je moguće pristupati komponentama agenta, definisanim u jezik u HADL.<br />AJA agent poseduje sledeće osobine:<br />- Sigurna kom unikacija sa drugim A JA agentim a koristeći mehanizam pregovaranja, &scaron;ifrovanje i digitalno potpisivanje poruka.<br />- Mogućnost adaptiranja na promene u okruženju u kom se nalazi, koristeći neuralne mreže i adaptabilne parametre.<br />- Reaktivnost zasnovana n a kom ponenti zvanoj refleks.<br />- Paralelno izvr&scaron;avanje akcija agenta u z njihovu internu sinhronizaciju.<br />- D ostupnost agenta preko Interneta. Agent se pona&scaron;a kao jednostavan HTTP server. Na ovaj način se drugim osobama omogućuje da komuniciraju sa agentom .<br />- G rafički korisnički interfejs zasnovan n a Java Swing tehnologiji<br />- Po&scaron;to se u program iranju agenta koristi Java+, moguće je uposliti sve pogodnosti Jave, kao &scaron;to su na primer pristup bazama podataka koristeći JDBC , rad sa multimedijalnim sadržajem , itd.<br />U tezi je predstavljen i originalni pristup integrisanja tehnika ve&scaron;tačke inteligencije sa program skim jezikom . U građujući kom ponente ve&scaron;tačke inteligencije u izvr&scaron;nu okolinu je z ik a čini n jihovo kori&scaron;ćenje veom a jednostavnim . Programer ne mora da bude ekspert iz ve&scaron;tačke inteligencije a da pri tome koristi konstrukcije jezika koje su implementirane pomoću ve&scaron;tačke inteligencije. AJA specifikacija agenta se sastoji od HADL i Java+ delova. U tezi je implementiran prevodioc kojim se A JA specifikacija prevodi u skup klasa programskog jezika Java. Implementiran je i jedan multi-agentski sistem kojim se praktično pokazuje kori&scaron;ćenje i mogućnosti napravljenog alata D oktorska teza sadrži i detaljan pregled oblasti o agentskpj m etodologiji.

<p>Рад је посвећен испитивању могућности, ефикасности, тешкоћа и ограничења примене корелацијско-интеграцијског методичког система у обради садржаја еколошког образовања. Прецизније речено, циљ рада је евалуација примене корелацијско-интеграцијског методичког система у обради еколошких садржаја, са аспекта припреме, реализације и ефеката у наставном процесу, посебно кад је реч о образовним постигнућима ученика у погледу нивоа, квалитета и ретенције усвојених наставних садржаја, затим са аспекта утврђивања предности и недостатака наведеног методичког система, као и мишљења о његовом значају од стране учесника васпитно-образовног процеса, првенствено ученика и наставника. Евалуација корелацијско-интеграцијског методичког система урађена је кроз неколико фаза: (а) праћење и вредновање припреме, организације и реализације експерименталног програма, (б) вредновање образовних постигнућа ученика, (в) сагледавање мишљења ученика и наставника о реализацији експерименталног програма. Како би се утврдило да ли постоји узрочно-последична веза између примене експерименталног програма и нивоа и квалитета знања ученика, коришћен је квази-експеримент са паралелним групама. Мерења која су урађена у три различита временска тренутка (иницијални тест, финални тест и ретест) омогућила су нам да<br />утврдимо напредак ученика у нивоу и квалитету знања, али и могућност ретенције знања ученика. Према резултатима нашег истраживања, експериментални програм који смо применили имао је ефекте на: (а) ниво знања и напредак ученика из области екологије; (б) квалитет знања и напредак ученика, пре свега, у домену примене стеченог знања; (в) веће задовољство и мотивацију ученика у наставном процесу и (г) позитивно мишљење о примени корелацијско-интеграцијског методичког система.</p> / <p>Rad je posvećen ispitivanju mogućnosti, efikasnosti, teškoća i ograničenja primene korelacijsko-integracijskog metodičkog sistema u obradi sadržaja ekološkog obrazovanja. Preciznije rečeno, cilj rada je evaluacija primene korelacijsko-integracijskog metodičkog sistema u obradi ekoloških sadržaja, sa aspekta pripreme, realizacije i efekata u nastavnom procesu, posebno kad je reč o obrazovnim postignućima učenika u pogledu nivoa, kvaliteta i retencije usvojenih nastavnih sadržaja, zatim sa aspekta utvrđivanja prednosti i nedostataka navedenog metodičkog sistema, kao i mišljenja o njegovom značaju od strane učesnika vaspitno-obrazovnog procesa, prvenstveno učenika i nastavnika. Evaluacija korelacijsko-integracijskog metodičkog sistema urađena je kroz nekoliko faza: (a) praćenje i vrednovanje pripreme, organizacije i realizacije eksperimentalnog programa, (b) vrednovanje obrazovnih postignuća učenika, (v) sagledavanje mišljenja učenika i nastavnika o realizaciji eksperimentalnog programa. Kako bi se utvrdilo da li postoji uzročno-posledična veza između primene eksperimentalnog programa i nivoa i kvaliteta znanja učenika, korišćen je kvazi-eksperiment sa paralelnim grupama. Merenja koja su urađena u tri različita vremenska trenutka (inicijalni test, finalni test i retest) omogućila su nam da<br />utvrdimo napredak učenika u nivou i kvalitetu znanja, ali i mogućnost retencije znanja učenika. Prema rezultatima našeg istraživanja, eksperimentalni program koji smo primenili imao je efekte na: (a) nivo znanja i napredak učenika iz oblasti ekologije; (b) kvalitet znanja i napredak učenika, pre svega, u domenu primene stečenog znanja; (v) veće zadovoljstvo i motivaciju učenika u nastavnom procesu i (g) pozitivno mišljenje o primeni korelacijsko-integracijskog metodičkog sistema.</p> / <p>The present study investigated the possibilities,<br />effectiveness, difficulties and limitations in<br />application of the correlative-integrative<br />approach in teaching ecological education. In<br />specific, the aim of this study was to evaluate<br />the correlative-integrative approach in teaching<br />ecological education. The evaluation of the<br />correlative-integrative approach was done in<br />three ways: (a) by following and evaluating<br />lesson preparation, organisation and realisation<br />of the experimental program; (b) by evaluating<br />student education achievements; and (c) by<br />interpreting students&rsquo; and teachers&rsquo; views on the<br />realisation of the experimental program. To<br />assess whether there is a cause-and-effect<br />relationship between the application of the<br />experimental program and a level and quality of<br />student knowledge we executed a pseudoexperiment<br />with paired groups. Data gathered at<br />three different testing periods (initial test, final<br />test and repeated test) allowed us to ascertain<br />student development in terms of level and<br />quality of knowledge, as well as retention of<br />knowledge. The empirical data obtained in this<br />study showed that the experimental program<br />was effect on: (a) the level of knowledge and<br />students&#39; progress in the field of ecology; (b) the<br />quality of knowledge and progress of students,<br />primarily in the domain of application of<br />acquired knowledge; (c) greater satisfaction and<br />motivation of students in the learning process<br />and (d) a positive opinion on the application of&nbsp;correlation and integration approach.</p>

Antal Silard 05 February 2013 (has links)
<p>U radu se proučava nastanak i razvitak televizije u svetu i u Jugoslaviji i osnivanje Televizije Novi Sad. Prve godine rada Televizije Novi Sad (1970 -1980) izučavane su kroz prizmu razvoja programa i auditorijuma, informativnu, kulturnu i obrazovnu funkciju, kao i kroz emisije zabavnog i sportskog karaktera. U radu su predstavljeni i svi faktori od značaja za osnivanje i razvoj Televizije Novi Sad: inicijativa za osnivanje, neizostavno tada&scaron;nja politička situacija, povoljne okolnosti za napredak inicijative, kao i raspoložive frekvencije za emitovanje programa u Vojvodini.<br />Ciljevi ovog istraživanja su da se ukaže na značaj osnivanja Televizije Novi Sad i njenu ulogu u razvoju medijske situacije u AP Vojvodini, kao i da se izvr&scaron;i analiza problema i prioriteta razvoja Televizije Novi Sad, odnosno političkih, dru&scaron;tvenih, kulturnih i informativnih razloga za osnivanje Televizije Novi Sad. Na ovaj način podaci koji su obrađeni, ostaju kao trajni istorijski presek, koji može poslužiti kao osnova nekih daljih istraživanja medijskog života u Pokrajini.<br />U istraživanju su analizirani ne samo razlozi za pokretanje i materijalna osnova i finansijska pomoć dru&scaron;tvenopolitičke zajednice Televizije Novi Sad i njena funkcija, koncepcija i fizionomija programa, već i &scaron;iroke političke konsultacije, informativne i komunikacijske obaveze dru&scaron;tvenopolitičke zajednice prema svom stanovni&scaron;tvu i politički, privredni i kulturni život u Pokrajini. Struktura gledalaca u Pokrajini, kulturni afiniteti i specifičnosti, ustavne promene u položaju, statusu i funkciji socijalističke AP Vojvodine, kao bitni faktori, takođe imaju svoje mesto u istraživanju.<br />Kori&scaron;ćeni su podaci iz zvaničnih i ličnih arhiva, kao i istraživanja i iskustva Centra za istraživanja javnog mnjenja, programa i auditorijuma, statut Televizije Novi Sad i konkretni primeri iz prakse kroz novinske članke objavljane u dnevnom listu &bdquo;Dnevnik&ldquo;.<br />Ovaj rad ima značaj u kontekstu razumevanja dana&scaron;njih uslova i stanja u kojem se medijski svet u AP Vojvodini nalazi. Značajno je i to &scaron;to su sublimirani upravo oni podaci, dokumenta i zabeležena iskustva o Televiziji Novi Sad koji bi u najvećoj meri bili izgubljeni ili prepu&scaron;teni zaboravu i uni&scaron;tenju.</p> / <p>In this dissertation the origin and progress of television in the world and in the former Yugoslavia, respectively the foundation of the Television of Novi Sad are examined. The first years of broadcasting of the Television of Novi Sad (1970-1980) are analysed through the prism of its informative, cultural and educative function; the progress of programmes&nbsp; and audiences as well as through entertaining and sports shows. Besides, all the factors are presented in this thesis which are significant for the foundation and progress of the Television of Novi Sad : the initiative for the foundation, the political situation of the time, adequate circumstances for the advancement of the initiative and the available broadcasting frequencies in the Autonomous Province of Vojvodina.<br />The aims of this research are to draw attention to the importance of the establishment of the Television of Novi Sad as playing a great part in the improvement of the situation regarding the media in the Autonomous Province of Vojvodina, moreover to analyse the problems and priorities of the progress of the Television of Novi Sad, respectively the political, social, cultural and informative reasons for its foundation. Thus, the processed data represent a permanent historical review , which may serve as a basis for further researches on the media of the Autonomous Province of Vojvodina.<br />During this research, beside the reasons for its launching, it was not only the financial basis and function of the Television of Novi Sad or the conception and physiognomy of its programmes that was analysed but also the wide political consultations, the informative and communicational duties of socio-political societies towards the civilian population, and the political, cultural and agricultural life in the Autonomous Province of Vojvodina. The structure of viewers, the cultural specificity and affinities, the constitutional changes in the status and function of the socialist Vojvodina as significant factors are as well part of this research.<br />The data and information was collected and used from various sources, such as: official and personal archives; researches and experience of the Centre for Public-Opinion Poll, Programmes and Audiences; the statutes of the Television of Novi Sad, furthermore particular examples from practice extracted from articles published in the daily paper &lsquo;Dnevnik&rsquo;.<br />This dissertation is of considerable importance in the context of understanding the status of the media in the Autonomous Province of Vojvodina today. Moreover, it is also a significant fact that exactly those data, documents and recorded experience are gathered here, which would all the way fall into oblivion or decay.</p>

Procena cerebralne autoregulacije primenom apnea testa kod simptomatske karotidne stenoze pre i posle karotidne endarterektomije / Evaluation of cerebral autoregulation by application of apnea test in patients with symptomatic carotid stenosis before and after carotid endarterectomy

Lučić Prokin Aleksandra 06 November 2015 (has links)
<p>TCD apnea test kao neinvazivna i bezbedna neuroultrasonografska metoda pruža korisne informacije o vazomotornoj reaktivnosti (VMR) u procesu indirektnog sagledavanja funkcionisanja moždane autoregulacije. Vazomotorna reaktivnosti podrazumeva sposobnost dilatacije ili konstrikcije moždanih arteriola nastale kao odgovor na određeni vazoaktivni stimulus, najče&scaron;će ugljen dioksid. Cilj ove doktorske disertacije bio je ispitivanje i analiziranje promene karotidne hemodinamike kod bolesnika sa ishemijskim moždanim udarom (IMU) ili tranzitornim ishemijskim atakom (TIA) i simptomatskom karotidnom stenozom u preoperativnom i tromesečnom postoperativnom periodu, kao i procena revaskularizacionog efekta karotidne endarterektomije (KEA).U istraživanje je uključeno 60 hospitalizovanih bolesnika koji su doživeli prvi IMU i TIA u zoni vaskularizacije arterije cerebri anterior (ACA) i arterije cerebri medije (ACM), svi sa karotidnom stenozom, ACI &ge;70%. Bolesnici su bili hospitalizovani na Klinici za neurologiju, Kliničkog Centra Vojvodine, Klinici za kardiovaskularnu hirurgiju, Instituta za kardiovaskularne bolesti Vojvodine i Klinici za vaskularnu hirurgiju, u Novom Sadu. U odnosu na kliničke manifestacije bolesni i su podeljeni u tri grupe: bolesnici sa TIA i amaurosis fugax, sa parcijalnim infarktom u zoni ACA ili ACM i sa lakunarnim infarktom. Istraživanje je analiziralo uticaj promenljivih i nepromenljivih vaskularnih faktora rizika na pojavu IMU i TIA, ali i na VMR, procenjivanu kroz indeks zadržavanja daha (Breath Holding Index, BHI) ipsilateralno i kontralateralno u odnosu na karotidnu stenozu. Analizirana je povezanost stepena karotidne stenoze sa vrednostima BHI preoperativno, povezanost BHI sa težinom kliničke slike, uticaj kolateralnog krvotoka na VMR, distribucija BHI u pojedinim tipovima IMU i TIA kao i komparacija BHI u pre i u postoperativnom periodu od 30 i 90 dana. Na osnovu sprovedenog istraživanja, do&scaron;lo se do zaključaka da je redukovana VMR preoperativna karakteristika karotidne stenoze ipsilateralno kao i karakteristika različitih tipova IMU i TIA ipsilateralno; postoji negativna korela ija izmeĐu stepena karotidne stenoze i BHI vrednosti. Nije potvrđena hipoteza da veći roj razvijenih kolateralnih puteva uslovljava očuvanu VMR; utvrđena je pozitivna korelacija između BHI vrednosti u preoperativnom i postoperativnom periodu; redukovana VMR ima negativan uticaj na težinu kliničke slike. Prepoznavanje vrednosti TCD apnea testa, koji se može koristiti kao komplementarna metoda drugim vazoaktivnim testovima u praćenju karotidne hemodinamike, od posebne je važnosti neurologu i vaskularnom hirurgu. Time bi se doprinelo daljoj evaluaciji mehanizma nastanka IMU, planiranju terapijskog pristupa i determinisanju prognoze operisanih bolesnika. Činjenica da većina neurolo&scaron;kih odeljenja poseduje TCD aparat, apnea test postaje dostupan svakom neurologu u kliničkom radu, posebno u na&scaron;im uslovima, kada se do drugih drugih, skupljih metoda, te&scaron;ko stiže ili nam ostaju nedostižne.</p> / <p>TCD apnea test, as a noninvasive and safe neuroultrasonographic method, provides useful information about vasomotor reactivity (VMR) in the indirect evaluation of cerebral autoregulation. Vasomotor reactivity is the ability of cerebral arterioles to constrict or to dilate in response to a vasoactive stimulus, mainly carbon dioxide. The aim of this doctoral thesis was to investigate and analyze changes in carotid hemodynamics in patients with ischemic stroke (IS) or transient ischemic attack (TIA) and symptomatic carotid stenosis in the preoperative and three-month postoperative period as well as the assessment of revascularisation effect of carotid endarterectomy (CEA). The study included 60 hospitalized patients who experienced a first ischemic stroke or TIA in the vasularisation area of anterior cerebral artery (ACA) and middle cerebral artery (MCA), all with carotid stenosis &ge;70% ACI. Patients were hospitalized at the Clinic of Neurology, Clinical Center of Vojvodina, Department of Cardiovascular Surgery, Institute of Cardiovascular Diseases and the Department of Vascular Surgery in Novi Sad. Considering clinical manifestations of stroke, the patients were divided into three groups: patients with TIA and amaurosis fugax, with partial infarction in area ACA or ACM and with lacunar infarct. The study analyzed the impact of variabile and unvariable vascular risk factors on the incidence of ischemic stroke and TIA, but also on VMR, evaluated through Breath Holding Index (Breath Holding Index, BHI) on the ipsilateral and contralateral side from carotid stenosis. We analysed the correlation between the degree of carotid stenosis with preoperative values of BHI, BHI correlation to the severity of clinical findings, the impact of collateral circulation to the VMR, distribution of BHI in certain types of ischemic stroke and TIA as well as comparison of BHI in the pre and postoperative period of 30 and 90 days. On the basis of this research came the conclusion that reduced VMR is characteristic of ipsilateral carotid stenosis in preoperative period as well as number of developed collateral characteristics of different types of ipsilateral ischemic stroke and TIA; there is a negative correlation between the degree of carotid stenosis and BHI values. The hypothesis that the greater pathways causes preservation of VMR was not confirmed, while the positive correlation between BHI values in the preoperative and postoperative period was established. Reduced VMR has a negative impact on the degree of clinical picture severity. Recognizing the importance of TCD apnea test method, that can be used as a complementary method to other vasoactive tests in monitoring of carotid hemodynamics, is of special importance to the neurologists and vascular surgeons. This would contribute to the further evaluation of mechanism of ischemic stroke, planning of therapeutic approach and determining the prognosis of treated patients. The fact that most of neurological department has TCD device, apnea test becomes available to every neurologist in clinical work, specially in our conditions, when other methods remain unattainable.</p>

Canton, Luciana Giannini 02 April 2019 (has links)
A técnica Meisner e as sementes do Sistema stanislavskiano plantadas em solo americano. 2019. 183f. Tese (Doutorado em Artes Cênicas) - Escola de Comunicações e Artes, Universidade de São Paulo, São Paulo, 2019. Esta tese propôs o estudo teórico da técnica Meisner, observando suas origens e as relações com o Sistema de Stanislavski. O objetivo dessa pesquisa foi analisar passo-apasso a técnica meisneriana para esclarecer quais são os procedimentos criados por ela e qual a sua filiação com o Sistema. O estudo questionou as possíveis origens dos seguintes procedimentos meisnerianos: o exercício da repetição, a atividade, o bater na porta, a preparação emocional, as imitações, impedimentos e o trabalho com cenas. Após esse panorama foi feita uma análise que estabelece paralelismos e distinções da técnica Meisner com alguns procedimentos do Sistema, apontando pontos de contato e inflexão entre eles, tais como: comunhão, círculo de atenção, memória afetiva, as circunstâncias propostas, o \"se mágico\" e o étude, mas constatou também diferenças significativas. Concluimos que dois elementos da técnica, apesar de inspirados em Stanislavski, foram criados por Meisner: o exercício da repetição e a preparação emocional. / The Meisner Technique and the Seeds on American Soil Planted by the Stanislavskian Sistem. 2019. 183p. Thesis (Doctorate in Theater) - School of Comunications and Arts, University of São Paulo, São Paulo, 2019. This thesis proposes the theorical study of the Meisner technique, observing its origins and relations with the Stanislavski\'s Sistem. The goal of this research was to analyse step by step the meisnerian technique and clarify which are the procedures created by it, and how is it related to the Sistem. The study questioned the possible origins of the following meisnerian procedures: the repetition exercise, the activity, the knocking on the door, the emotional preparation, imitation, impediments and the work with scenes. After this panorama, was made an analysis that stablished distinctions and paralelisms between the Meisner technique and some procedures of the Sistem, pointing spots of contact and inflexion between them, such as: communion, circle of attention, affective memory, given circunstances, the \"magic if\" and the étude, but found also significative differences. This theses concludes that two elements of the Meisner technique, besides being inspired by Stanislavski, were created by Meisner: the repetition exercise and the emotional preparation.

A hybrid BCI (hBCI) consists of a combination of two or more types of BCIs, two or more signal acquisition techniques, or a combination of BCI with other non-BCI based interaction techniques. A Collaborative BCI (cBCI) integrates the brain activity of a group of individuals, mainly acting in the increase of the human capacity. Low-cost electroencephalogram (EEG) equipment is currently available in the market, one of which is the Emotiv EEG, which is portable, has 14 electrodes, and in addition to registering the neurophysiological signals, it processes and makes available them in the form of neural measurements, such as levels of attention and excitement. In addition to neural measures, other measures may reveal an individual's behavior, such as the speed with which he responds to a challenge, which may suggest how confident he is about this decision-making. This work has as main objective "To verify if neural and behavioral measures have relation with the right and wrong decision making". Initially, a systematic review of the literature was carried out. Afterwards, a data collection system and a decision-making task based on Rapid Serial Visual Presentation (RSVP) were developed. The experiment consisted of 10 participants, in which each one performed 112 tests, recording the neural measurements taken by Emotiv EEG, besides the Reaction Time (RT) as a behavioral measure and the response given by the user, both collected by a conventional keyboard. Statistical techniques, such as descriptive analysis, including data summarization and boxplot charts, and multivariate analysis were used for the data analysis, using logistic regression to estimate the relationship between neural and behavioral measures with the decisions made. The proposed task proved to be efficient, revealing in the results that the difficulty was effective. The developed database proved to be efficient in synchronizing the task data and the recorded measurements. After different approaches of statistical analysis of the data, a regression model that could explain with high explanatory power the data sampled was not found. Thus, based on the experiment performed and statistical analyzes, no relationship was found between neural and behavioral measures and the correct or wrong decision-making. / Interface C?rebro-M?quina (ICM) ou Interface C?rebro-Computador (ICC) ? um sistema computacional capaz de estabelecer a comunica??o entre a atividade neurofisiol?gica humana e um computador. Uma ICC h?brida (ICCh) consiste na combina??o de dois ou mais tipos de ICC, duas ou mais t?cnicas de aquisi??o de sinal, ou, ainda, da combina??o de uma ICC com outras t?cnicas de intera??o n?o baseadas em ICC. Uma ICC Colaborativa (ICCc) integra a atividade cerebral de um grupo de indiv?duos, atuando, principalmente, no aumento da capacidade humana. Atualmente, no mercado, est?o dispon?veis equipamentos de Eletroencefalograma (EEG) de baixo custo, sendo um desses o Emotiv EEG, que ? port?til, possui 14 eletrodos, e, al?m e registrar os sinais neurofisiol?gicos, os processa e disponibiliza em forma de medidas neurais, como, por exemplo, n?veis de aten??o e excitamento. Al?m de medidas neurais, outras medidas podem revelar o comportamento de um indiv?duo, como, por exemplo, a velocidade com que responde um desafio, que pode sugerir o qu?o confiante ele est? sobre esta tomada de decis?o. Este trabalho tem como principal objetivo ?Verificar se medidas neurais e comportamentais possuem rela??o com as tomadas de decis?o corretas e erradas?. Inicialmente, foi realizada uma revis?o sistem?tica da literatura. Ap?s, foram desenvolvidos um sistema de coleta de dados e uma tarefa de tomada de decis?o baseada em Rapid Serial Visual Presentation (RSVP). O experimento contou com 10 participantes, no qual cada um executou 112 ensaios, sendo registradas as medidas neurais captadas pelo Emotiv EEG, al?m do Tempo de Rea??o (RT) como medida comportamental e, a resposta dada pelo usu?rio, ambas coletadas por um teclado convencional. Para a an?lise dos dados, foram aplicadas t?cnicas de estat?stica, tais como an?lise descritiva, incluindo sumariza??o dos dados e gr?ficos de boxplots, e an?lise multivariada, utilizando regress?o log?stica para estimar a rela??o entre medidas neurais e comportamentais com as decis?es tomadas. A tarefa proposta mostrou-se eficiente, revelando nos resultados que a dificuldade empregada se mostrou efetiva. O banco de dados desenvolvido mostrou-se eficiente na sincroniza??o dos dados da tarefa e as medidas registradas. Ap?s diferentes abordagens de an?lise estat?stica dos dados, n?o foi encontrado um modelo de regress?o que pudesse explicar com alto poder explicativo os dados amostrados. Desta maneira, baseado no experimento realizado e nas an?lises estat?sticas, n?o foram encontradas rela??es entre medidas neurais e comportamentais e as tomadas de decis?o corretas ou erradas.

No. of bitstreams: 1 438775.pdf: 1449047 bytes, checksum: c68e1c5fe4bd1a3071995d84cf7f9f62 (MD5) Previous issue date: 2012-03-28 / This dissertation analyses the theological conception of Christian laymen of the Catholic Church language and doctrine. Part of ecclesiology as the theological place of constant existence of laity in the ecclesial tradition, analyzing the historical and theological factors, in which nuances are evidenced in form and degree of involvement of lay members in Church`s mission. From this dialectic perspective, by the nature of ecclesiology because of the invisible and visible dimension of Church as the only reality in history, the phenomenon of the Catholic Action to comprehend the pastoral and theological horizon of council priests in the Council Vatican II was studied. Contextualization properly given, historical and theological of the council event, the interpretation of IV chapter of Dogmatic Constitution Lumen Gentium about the Church was developed, in which is explained the theological dogmatic nucleus about the laity of the Catholic Church. Once this theological nucleus was identified, conclusive texts of General Conferences of the Episcopate of Latin America CELAM, were analyzed, ascertaining its respective theological development, in which it is found the integral perception, but gradual of conception of Christian laymen emitted by Vatican Council II. This graduallity means that the conferences accentuate some theological aspects about laymen, in consonance with the challenges of the evangelizing mission of Church in Latin America`s reality. In the entirety of the dissertation, the secular vocation of the laity can be evidenced as one advance of Vatican Council II and the respective effort of CELAM conferences in effect it ecclesially. / Esta disserta??o analisa a concep??o teol?gica dos crist?os leigos na linguagem e doutrina da Igreja Cat?lica. Parte da eclesiologia como o lugar teol?gico da exist?ncia constante do laicato na tradi??o eclesial, analisando os fatores de natureza hist?rica e de natureza teol?gica segundo os quais se evidenciam nuances na forma e no grau de envolvimentos dos membros do laicato na miss?o da Igreja. A partir dessa perspectiva dial?tica, pr?pria da natureza da eclesiologia por causa da dimens?o invis?vel e vis?vel da Igreja como ?nica realidade na hist?ria, foi estudado o fen?meno da A??o Cat?lica para compreender o horizonte pastoral e teol?gico dos padres conciliares no Conc?lio Vaticano II. Dadas ?s devidas contextualiza??es, hist?ricas e teol?gicas, do evento conciliar, desenvolve-se a interpreta??o do IV cap?tulo da Constitui??o Dogm?tica Lumen Gentium sobre a Igreja, no qual ? explicitado o n?cleo teol?gico-dogm?tico sobre o laicato da Igreja Cat?lica. Uma vez identificado esse n?cleo teol?gico foram analisados os textos conclusivos das Confer?ncias Gerais do Episcopado da Am?rica Latina CELAM, averiguando o seu respectivo desenvolvimento teol?gico, onde se constata a recep??o integral, mas gradual da concep??o dos crist?os leigos emitida pelo Conc?lio Vaticano II. Essa gradualidade significa que as confer?ncias acentuam alguns aspectos teol?gicos sobre os leigos, em conson?ncia com os desafios da miss?o evangelizadora da Igreja na realidade da Am?rica Latina. No conjunto da disserta??o evidencia-se a voca??o secular dos leigos como um dos avan?os do Conc?lio Vaticano II e o respectivo empenho das Confer?ncias do CELAM em efetiv?-la eclesialmente.
