SYFTE Syftet med denna uppsats är att analysera hur kommunikations- och samspelsförmåga uttrycks över tid när en ung man på tidig utvecklingsnivå och med autism deltar i en dyad i sherbornebehandling. Frågeställningar: Hur utvecklas kommunikations- och samspelsförmåga över tid i behandlingssituationen? Hur utvecklas kommunikations- och samspelsförmåga i hemmet respektive skolan under samma tidsperiod?   METOD Denna pre-experimentella fallstudie rör en 18-årig man som under drygt ett år kom till habiliteringen för att delta i arton sherbornebehandlingar med en sjukgymnast med mångårig erfarenhet av sherbornemetodik. Sherborne är en rörelsemetodik där rörelser används för att utveckla rums- och kroppsmedvetenhet och skapa relationer till andra. Samtliga arton behandlingar videofilmades och data insamlades via observation. En detaljerad nedteckning av händelseförloppet i en videoinspelning i början av behandlingsperioden och en i slutet gjordes. Under arbetet med att analysera kommunikation och samspel i videoinspelningarna uppkom behovet av att komplettera Sherbornes samspelsskala med ett bedömningsmaterial för att kunna analysera kommunikation och samspel i detalj med personer på tidig nivå, ”Brandquists & Althoffs Samspelsskala: Analys av samspel med personer på tidig utvecklingsnivå - Sherborne”, bilaga 7. För att öka tillförlitligheten i resultatet inhämtades dels kommentarer från deltagande sjukgymnast och mannens förälder under det att de såg de båda videofilmerna, dels gjordes en översiktlig analys av tio övriga videoinspelningar från sherborneperioden. Förälder och lärare intervjuades före och efter behandlingsperioden om den unge mannens kommunikation och samspelsförmåga i hemmet och på skolan. RESULTAT Resultat visar på en positiv effekt på den unge mannens förmåga till kommunikation och samspel. Under sherborneperioden framkommer gradvis en förändring av hur mannen riktade sin uppmärksamhet: från att blicken var ”tom” eller att blicken svepte över rummet till att han allteftersom kroppsligen riktade sig mot sjukgymnasten och sökte blickkontakt. Sjukgymnasten anpassade sitt förhållningssätt för att få till stånd ett så bra samspel som möjligt. Från att hon i början var mer inlyssnande och använde beröring för att bekräfta hans reaktioner, till användandet av ett ökat verbalt inslag mot slutet. I slutet av perioden började den unge mannen ta egna initiativ till samspel genom att rikta sin hand mot sjukgymnasten. Även i hem och skola ökade hans intresse för omgivningen. Han tog initiativ till kommunikation (ett ökat antal handlingssekvenser) och var på gång att utveckla delad uppmärksamhet. Han började säga ifrån mer genom att använda sin röst. Det självskadande beteendet minskade både under sherbornebehandlingen och i hemmet. I övrigt märkte både förälder och sjukgymnast en ökad balans och stabilitet i hans kropp och en förbättrad rörelseförmåga i hans svaga högersida.   SLUTSATSER Fallstudien tyder på att sherbornemetodik kan ha bidragit till en positiv effekt på såväl kommunikation och samspelsförmåga som rörelseförmåga hos denne unge man på tidig utvecklingsnivå och med autism. / INTRODUCTION Caregivers perceive many of difficulties in interaction with persons at a presymbolic stage. In Sherborne Developmental Movement the theoretical issue is that movement experiences developing body and spatial awareness contribute to awareness of self. This gaining of body mastery is fundamental to the awareness of others, the ability to relate to others.   The aim of this study is to analyse how communication and interaction is expressed over a period of time as a young man in an early stage of language development (pre-intentional communication) and with autism participates in a dyad in SDM sessions. Research questions:1. How do communication and interaction skills develop over time in the SDM sessions? 2. How do communication and interaction skills develop at home and school during the same period? METHOD In this pre-experimental case study an 18-year-old man with profound autism spectrum disorder, a right-sided motor disorder and a severe language impairment is participating. Giving no responses in communication, caregivers rarely perceived successful interaction. He suddenly burst out in aggressive acts. Lasting over a year he participated in an intervention consisting of eighteen SDM sessions in a dyad with a physiotherapist, skilled in SDM, at Habilitation Centre. Sessions were based on a “caring” SDM-relationship and treatment focused on basic movements. All sessions were videotaped. Communication and interaction skills were thoroughly assessed at the first and last session. In the process of analysing data the SDM scale of type of relation had to be supplemented by scales showing abilities of communication and interaction of the leader and the participant. This scale named "Brandquists & Althoff Interaction Scale: Analysis of the interaction with individuals at an early stage of development - Sherborne”, was used in reporting the data obtained in the study. To increase the reliability of the data, comments from the participating physiotherapist and the father of the young man were registered while they individually watched the two video recordings. A somewhat simplified examination of ten of the video recordings was also made. Communication and interaction skills were also investigated at home and school through interviews and questionnaires before and after the SDM treatment. These data were then to be compare to the data of the SDM sessions.   RESULTS Results show a positive effect on communication and interaction skills of the young man. During the period of sessions he gradually changed the way of directing attention. Initially his eyes were "empty" or his gaze swept across the room to him. Later he focused on the hands of the physiotherapist while rocking his leg and eventually he physically directed himself to the physiotherapist and searched eye contact. The physiotherapist was sensitive to his physical reactions adapting her approach in order to making him feel secure and achieve trust. In the beginning she used tactile methods in her communication, but seeing he felt more secure she introduced more verbal confirming towards the end.  At the end of the period he began to take communicative initiatives by approaching his hand and “pointing” at the physiotherapist.   At home and school caregivers reported an increasing interest in the environment. He used more initiative for communication (an increased number of action sequences) and was on his way to develop joint attention. He started to use his voice to protest. The number of self-destructive behaviours decreased during the Sherborne sessions and at home. Successively he gained greater stability and balance in his body and the mobility of the weak side improved. The data obtained in interviews with caregivers confirmed the results achieved in the study and strengthened the reliability of the results of SDM. CONCLUSIONS The result of the study implies that SDM may have contributed to a positive effect on the communication and interaction skills of this young man.

As the interest in intentional electromagnetic interference (IEMI) increases, so does the need of a suitable antenna which endures those demanding conditions. The ultrawideband (UWB) technology provides an elegant way of generating high-voltage UWB pulses which can be used for IEMI. One UWB antenna, invented solely for the purpose of radiating pulses, is the impulse radiating antenna (IRA). In the course of this master thesis work, a suitable geometry of the IRA is suggested, and modelled, for the high-voltage application of 90 kV.

Purpose: The current thesis assignment aims to explain, understand and follow the strategies the young children employ into a conception of numbers. This thesis is based on a study performed by Doverborg and Pramling Samuelson. The following research questions serve to refine the stated goal: How mathematical thinking regarding conception of numbers occurs within younger children and which strategies they use? How is the interaction between the teacher and the younger children? Method: The study is organized as a qualitative study and was conducted in a pre-school with a group of four children. The children that have participated within my study are between two and three years old. They were filmed in four exercises. Then the films were transcribed. The method used is an analytic approach intentional analysis which allows studying the children´s strategies according to the established questions and also it makes it possible to follow how they think regarding mathematics. Conclusion: My study group shows in the final results that they in their strategies made use of one or more principles in their conception of numbers. / Syfte: Bidra till en bättre förståelse för små barns tänkande kring matematik. Jag utgår ifrån Doverborg och Pramling Samuelsons studie som behandlar antalsuppfattning i matematik hos de yngsta barnen. Följande frågeställningar syftar har undersökts: Hur sker de yngsta barnens matematiska tänkande omkring antalsuppfattning och vilka strategier de använder sig av? Hur sker samspelet mellan pedagogen och de yngre barnen? Metod: Studien är upplagd som en kvalitativ studie och genomfördes i en förskola med en grupp på fyra barn. De barn som har deltagit i min studie är mellan två och tre år gamla. De filmades i fyra övningar varefter filmsekvenserna transkriberades. Metoden som använts är en analytisk metod intentionell analys som gör det möjligt att studera barnens strategier i enlighet med fastställda frågor och även gör det möjligt att följa hur de tänker om matematik. Slutsats: Min undersökningsgrupp visar i slutresultatet att de i sina strategier använde sig av en eller flera principer i antalsuppfattning, nämligen principen om ett till ett korespondens, principen om den stabila ordningen, kardinalprincipen, och principen om godtycklig ordning. Barnen kan också urskilja grupper av två eller tre föremål, det vill säga subitizing.

Background: Injury is an enormous public health problem in Canada. Recent studies have suggested that characteristics of the residential environment, particularly neighborhood marginalization, may be important in determining injury risk. Objective: To determine whether there is an association between neighborhood marginalization and injury in the largest urban cities of Ontario. Methods: A retrospective, cross-sectional, ecological study was conducted to evaluate the relationship between neighborhood marginalization and injury in 0-64 year olds who resided in the ten largest cities of Ontario between 2003-2005. Results: Neighborhoods with high levels of ethnic diversity had significantly lower rates of unintentional injuries, neighborhoods with high levels of material deprivation had significantly higher rates of assaults, and neighborhoods with high levels of residential instability and material deprivation had significantly higher rates of self-inflicted injuries in adults. Conclusions: The association between neighborhood marginalization and injury differs depending on the type of injury examined.

Viena aktualiausių jūros aplinkos apsaugos problemų - tyčiniai neteisėti teršalų išmetimai iš laivų, pažeidžiant tarptautinius aplinkosauginius reikalavimus. Nors pavieniai neteisėti naftuotų vandenų išmetimai iš laivų dažniausiai nėra dideli, tačiau bendras visų neteisėtų išmetimų kiekis yra didžiulis. Tarptautinė jūrų organizacija, supratusi problemos svarbą, patvirtino 1973 metais tarptautinę konvenciją dėl taršos iš laivų prevencijos, kuri vėliau virto MARPOL 73/78. Tačiau nepaisant to, kad šiuo metu MARPOL 73/78 taikoma 99 % pasaulinio laivyno, pavyzdžiui Baltijos jūroje kasmet apžvalgos skrydžių metu užfiksuojama apie 400 neteisėtų išmetimų iš laivų, tačiau jų būna gerokai daugiau. Tokiais atvejais teršėjai paprastai nėra nustatomi, nežinoma, kiek ir kokių teršalų pateko į jūrą. Tyčiniai neteisėti naftuotų vandenų išmetimai iš laivų tai dėl ekonominių, finansinių paskatų atliekamas pažeidimas. Pažeidėjas gali turėti gan reikšmingos finansinės naudos nepriduodamas laive susidarančių atliekų (naftuotų vandenų) ar krovinio likučių į uosto atliekų priėmimo įrenginius, tiesiog juos išmesdamas į jūrą. Be to, pažeidėjai turi ekonominį pranašumą prieš tuos laivų savininkus ar įmones, kurios išleidžia nemažai lėšų investuodami į aplinkosaugines technologijas, kad tinkamai vykdytų taršos iš laivų reikalavimus. Lietuvoje nuo 1997 m. nebuvo nustatyta nei vieno neteisėto tyčinio naftuotų vandenų išmetimo iš laivų. Siekiant įgyvendinti tarptautinius ir ES reikalavimus taršos iš...

While the individual discharges are not always large, the accumulative effect is significant. The importance of the problem was recognised by International Maritime Organization. International Convention for the Prevention of Pollution from Ships 1973 and Protocol of the 1978 relating to the International Convention for the Prevention of Pollution from Ships 1973 (MARPOL 73/78) was adopted. Today MARPOL 73/78 is applicable for 99 % World shipping tonnage. About 400 illegal oil discharges are observed during areal surveillance flights every year in the Baltic Sea, but obviously there are more of them. Usually in such cases polluter is unknown and there is no information what kind of oil is spilled and how much. Illegal discharges from ships are an economically motivated violation, that can involve significant gain for those violating the law. The offender can have significant financial benefit not discharging ship generated waste to port reception facilities, but discharging them into the sea. In addition, those violating the law have an unfair economic advantages over companies spending the necessary money to comply with the law. There were no illegal discharges detected in Lithuania since 1997. In order to implement international and EU requirements in the field of prevention pollution from ships, the amendments of the Low on Marine Environment Protection and the Law on State...

The increasing demand for energy, coupled with the difficulties inherent in the implementation of large generation projects, significantly increased the use of energy resources from renewable energy sources, in order to better meet the energy market. Recent research shows that there are several benefits of using the Distributed Generation in relation to large enterprises Centralized Generation. In this sense, this work shows the results of studies conducted in order to verify the feasibility of taking advantage of the Distributed Generation to meet the remaining local loads in any power shortages Distributor. This operation is called Intentional Islanded Operation. In order to implement the intentional islanding operation of Distributed Generation, it is necessary to carry out specific studies to meet the levels of quality and continuity established by regulations and to ensure the safety of the electrical system. Thus, this work presents an analysis of the technical feasibility of intentional islanded operation of distributed generators, given the restrictions imposed resulting from Power Flow studies, Transient Stability and Short Circuit. / O crescente aumento da demanda de energia, associado às dificuldades inerentes à implantação de empreendimentos de geração de grande porte, aumentou significativamente o aproveitamento dos recursos energéticos a partir de fontes de energia renováveis, visando um melhor atendimento do mercado de energia. Pesquisas recentes mostram que há diversas vantagens em se utilizar a Geração Distribuída em relação aos grandes empreendimentos de Geração Centralizada. Neste sentido, esta dissertação mostra os resultados de estudos realizados com o objetivo de verificar a viabilidade em se aproveitar as Gerações Distribuídas para o atendimento das cargas locais remanescentes, em eventuais faltas de energia da Distribuidora. Esta operação é denominada de Operação Ilhada Intencional. Para que a operação ilhada de Geradores Distribuídos possa ser admitida, estudos específicos devem ser realizados, a fim de que os níveis de qualidade e continuidade exigidos pelos órgãos reguladores sejam atendidos e que a segurança do sistema elétrico seja preservada. Desta forma, esta dissertação apresenta uma análise da viabilidade técnica da operação ilhada intencional de Geradores Distribuídos, considerando as restrições resultantes impostas a partir de estudos de Fluxo de Potência, Estabilidade Transitória e Curto-Circuito.

Nowadays due to the increase of renewable energy sources, Distributed Generations (DGs) assumed an important role in distribution and sub transmission systems. However, abnormal operating conditions of the distribution system may cause that the DG remains isolated from the main system and connected to part of distribution system feeding its local loads. This operating condition is known as DG islanding. There are many island detection techniques however they can fail in some situation, such as in cases of low power unbalance. This work aims to present three news passive island detection technique for synchronous Distributed Generation that has better performance than the traditional one. The first technique aims to attenuates the oscillations caused in the frequency by short circuits and load switching using Mathematical Morphology. The MM reduces frequency oscillations, and in this way it allows to reduce the thresholds. With smaller thresholds is possible the detection of small power mismatch and in a much smaller time. The second technique is based on Frequency Oscillation Estimation in order to distinguish the islanding from other events that may occur in distribution systems. This island detection algorithm uses a small time window to estimate the oscillation frequency, obtaining faster responses than the existing methods which use larger windows to estimate the damping and frequency of oscillation. The third method aims to recognize de frequency shape through a pattern recognition algorithm. The algorithm uses singular value decomposition and linear discrimination analysis to classify the events. The algorithms performances have been tested considering several generation and load scenarios including short circuits, load and capacitor switching, DG outage and islanding. The proposed methods were compared with the island detection method commonly used, i.e. Rate of Change of Frequency and Under / Overfrequency. The proposed methods are reliable since they do not trip for the most of non-islanding event. Among the tested methodologies, the method of the Frequency Oscillation Estimation has the best performance. Its detection time is less than 40ms and it Non Detection Zone is smallest than the range between + 3.2% and -1.6% of the GD rated power. The mathematical simplicity of EFO is adequate for practical relay implementation and the results show that EFO performs better than the other techniques. / Atualmente, devido ao aumento das fontes de energia renováveis, a Geração Distribuída (GD) assumiu um papel importante nos sistemas de distribuição e subtransmissão. No entanto, condições anormais de operação podem fazer com que a GD seja desconectada do sistema principal e permaneça conectada a uma parte menor do sistema, alimentando apenas suas cargas locais. Esta condição de operação é conhecida como ilhamento não intencional da GD. Existem diversas técnicas de detecção de ilhamento, porém, estas podem falhar em determinadas situações como em casos de baixo desbalanço de potência. Este trabalho apresenta três novas técnicas para detecção de ilhamento de gerações distribuídas com geradores síncronos, as quais apresentam melhores desempenhos que as técnicas tradicionais. A primeira metodologia proposta utiliza a Morfologia Matemática (MM) e visa atenuar as oscilações de frequência causadas por curtos-circuitos e comutação de carga. A MM reduz as oscilações e desta forma permite a redução dos limiares de detecção. Com limiares menores é possível detectar desbalanços de potência menores e em um tempo muito menor. A segunda técnica utiliza a Estimação da Frequência de Oscilação (EFO) e busca distinguir ilhamentos de outros eventos que podem ocorrer no sistema de distribuição. Nesse caso, o algoritmo de detecção de ilhamento utiliza uma pequena janela de tempo para estimar a frequência de oscilação. Assim, obtém uma resposta mais rápida do que os métodos até então existentes, que estimam o amortecimento e a frequência de oscilação. O terceiro visa reconhecer a forma da frequência através de um algoritmo de reconhecimento de padrão. O algoritmo utiliza decomposição em valores singulares e análise linear discriminante para promover a classificação dos eventos. Os desempenhos dos algoritmos foram avaliados com base em diversos cenários de geração e de carga, incluindo curtos-circuitos, chaveamentos de carga e de banco de capacitores, saída de GD e ilhamento. Os métodos propostos foram comparados com os algoritmos de detecção de ilhamentos comumente utilizados, ou seja, a Taxa de Variação da Frequência e Sub/Sobrefrequência. Os métodos propostos se mostraram confiáveis uma vez que não operam para a maioria dos eventos que não se caracterizam como ilhamentos. Dentre as metodologias testadas, o método da estimação da frequência de oscilação é o que apresentou melhor desempenho. Seu tempo de detecção é menor que 40ms e sua Zona de Não Detecção (ZND) é inferior a faixa situada entre +3,2% e -1,6% da potência nominal da GD. A simplicidade matemática da EFO favorece sua implementação prática, e os resultados mostram um desempenho bem superior quando comparado a outras técnicas já implementadas.

The author's premise that the school has the function of transmitting sociohistorically constructed and organized knowledge by humanity which allows us to affirm the impact of educational institutions in the formation of scientific concepts and in the increase of socio-cognitive and communicative skills since the early years. In this line of thought, it is understood that professionals working in childhood education contexts have the function of mediating learning and facilitating the development of higher psychological functions, essential for the constitution of gradually complex social relationships. Thus, the role of infant educator's conceptions about child development, especially their conceptions about intentional communication skills, is emphasized, considering the importance of these conceptions for established interactions and for global and language development. Thus, the main objective of this research is to know and analyze the conceptions and actions of children's educators and school psychologists about the development and the ability of intentional communication of children who are inserted in contexts of Reference Center in Early Childhood Education (CREI), in the city of João Pessoa-PB. This study included 4 school psychologists and 34 children's educators working in CREI's in the city of João Pessoa- PB. Of the 34 children educators interviewed, 11 worked with children from six months to one year of age (nursery I and II) and 23 worked with children from 2 to 3 years of age (maternal I and II). Psychologists worked with children from six months to six year old. The participants' ages varied between 19 and 61 years of age, with an average of 40.0 (SD = 29.6). The following were used as instruments: a socio-demographic questionnaire, the interview script on educator and psychologist conceptions about child development and education, and the Interview on the Perception of School Educators and Psychologists about the Children Intentional Communication Ability. The analysis of the collected material followed the guidelines of the content categorization method, proposed by Bardin (2009) and of academic productions related to the area of school psychology and child development. The collection of information indicated, in general, that child educators perceive child development through the child's resolution of the activities proposed in the classroom and the behaviors they exhibit in play situations. School psychologists have reported that child development is a continuous process that can be perceived through the interaction situations between the adult and the child. Both groups of professionals emphasized the importance of planning for the elaboration of pedagogical activities in the context of early childhood education. Three of the four psychologists interviewed reported a performance with the educators, the technical staff, the family and the children. Concerning intentional communication skills, most child educators and school psychologists have reported that children's emotional expressions are intentional and assist in non-verbal communication between adult and infant. Children's gestures appeared in the participants' discourse as a strong indicator of intentional communication in the child, mentioned mainly by psychologists. This study reaffirms the importance of intentional communication skills for the overall development of children and the influence of conceptions on child development in the work of education professionals. Recognizing the importance of this ability to / in the educator-child interactions favors the elaboration of intentional pedagogical proposals and interventions of psychologists in these contexts, aiming at reframing and mobilizing conscious, critical and intentional professional practices, promoters of learning and development. / A presente pesquisa fundamenta-se nos pressupostos da Teoria Histórico-cultural de Vygotsky para quem o desenvolvimento humano é favorecido por interações sociais mediadas por sujeitos mais experientes da cultura. A premissa desse autor de que a escola tem a função de transmissão dos conhecimentos sociohistoricamente construídos e organizados pela humanidade, o que permite afirmar o impacto de instituições de educação na formação de conceitos científicos e no incremento de habilidades sociocognitivas e comunicativas desde os anos iniciais. Nesta linha de pensamento, entende-se que os profissionais que trabalham em contextos de educação infantil tem a função de mediar o aprendizado e facilitar o desenvolvimento das funções psicológicas superiores, essenciais para a constituição de relações sociais gradativamente complexas. Dessa forma, enfatizase o papel das concepções de educadores infantis acerca o desenvolvimento infantil, em especial, de suas concepções sobre a habilidade de comunicação intencional, considerando a importância dessas concepções para as interações estabelecidas e para o desenvolvimento global e da linguagem. Dessa forma, o objetivo principal dessa pesquisa é conhecer e analisar as concepções e ações de educadoras infantis e psicólogas escolares sobre o desenvolvimento e a habilidade de comunicação intencional de crianças que estão inseridas em contextos de Centro de Referência em Educação Infantil (CREI), na cidade de João Pessoa- PB. Participaram desta pesquisa 4 psicólogas escolares e 34 educadoras infantis que trabalham em CREI's da cidade de João Pessoa- PB. Dentre as 34 educadoras infantis entrevistadas, 11 trabalhavam com crianças de seis meses a um ano de idade (berçário I e II) e 23 trabalhavam com crianças de 2 a 3 anos de idade (maternal I e II). Já as psicólogas trabalhavam com crianças de seis meses a seis anos de idade. A idade das participantes variou entre 19 e 61 anos de idade, com média 40,0 (DP=29,6). Como instrumentos, foram utilizados: um questionário sócio-demográfico, o Roteiro de entrevista sobre concepções de educadores e psicólogos acerca do desenvolvimento e educação infantil e a Entrevista sobre percepção de educadores e psicólogos escolares acerca da habilidade de comunicação intencional de bebês/crianças. A análise do material recolhido seguiu as diretrizes do método de categorização de conteúdo, proposto por Bardin (2009) e de produções acadêmicas ligadas à área da psicologia escolar e do desenvolvimento infantil. A recolha das informações indicou, de um modo geral, que as educadoras infantis percebem o desenvolvimento infantil a partir da resolução, por parte da criança, das atividades propostas em sala de aula e pelos comportamentos que exibem em situações de brincadeira. Já as psicólogas escolares relataram que o desenvolvimento infantil é um processo contínuo e que pode ser percebido através das situações de interação entre o adulto e a criança. Ambos os grupos de profissionais destacaram a importância do planejamento para elaboração de atividades pedagógicas no contexto de educação infantil. Três das quatro psicólogas entrevistadas relataram uma atuação junto aos educadores, com a equipe técnica, a família e as crianças. No que diz respeito à habilidade de comunicação intencional, a maioria das educadoras infantis e das psicólogas escolares relataram que as expressões emocionais infantis apresentam um caráter intencional e auxiliam na comunicação não-verbal entre adulto e bebê. Os gestos infantis compareceram, no discurso das participantes, como um forte indicador de comunicação intencional na criança, mencionado principalmente pelas psicólogas. Esse estudo reafirma a importância da habilidade de comunicação intencional para o desenvolvimento global infantil e a influência das concepções sobre o desenvolvimento infantil na atuação dos profissionais da educação. Reconhecer a importância dessa habilidade para/nas interações educadora-criança favorece a elaboração de propostas pedagógicas intencionais e intervenções de psicólogos nesses contextos, visando resignificar e mobilizar práticas profissionais conscientes, críticas e intencionais, promotoras de aprendizado e desenvolvimento.
