TITLE: Experiments in DGS AUTHOR: Michal Sláma DEPARTMENT: Department of Mathematics and Mathematical Education SUPERVISOR: doc. RNDr. Antonín Jančařík, Ph. D. ABSTRACT The aim of this diploma thesis is to find out whether the pupils of the second stage of primary school, specifically the pupils of the 6th grade, are able to experiment independently in the environment of dynamic geometry with a suitably prepared material. The theoretical basis of the work includes the study of the valid intended curriculum of geometry at the second stage of primary school, the relationship of so-called inquiry-oriented teaching to the possibility of student experimentation in learning geometry, the study of pedagogical theories in connection with inquiry education and also in relation to mathematisation, which is in the teaching of mathematics and geometry necessarily required. The student experiment is conceived here as an independent didactic method. From the point of view of the feasibility of the experiment and subsequent research, the environment of dynamic geometry was chosen - the GeoGebra system. The theoretical part of the work ends with a description of parameters important for the feasibility of experimentation in the environment of dynamic geometry in the teaching of geometry. The research part deals with the...

Dissertation was worked on the theme " Project and surveying of the network for planimetry and hight points in the area of the river Jenín using several methods". Target of this dissertation was building of point field, their planimetry and altitude destination like basis for another telemetry in range. On the basis of geodetic and map data was effected reconnaissance of the area, estimation of current point field, their completion to required density and locating new points by geodetic and GPS methods. It was built net of 16 points of the detailed planimetry point field and eight of them was subjekt of my dissertation. For planimetry and altitude survey by GPS method was used Trimble 4600LS device. By geodetic method points was located by electronic total station Leica TCR 407 power. Altitude of the three points was determined by the technical levelling using levelling machine Topcon AT {--} 22A and the other hights of points was calculated trigonometrically. Part of dissertation was processing of surveyed data, execution of graphic enclosure and comparing both methods.

This thesis is about mapping of the southern surroundings of the area caves Výpustek in the ratio scale 1:500 with the schematic mapping of the subterranean part of the cave. The theoretical part is devoted to the history of this cave and creating maps. The practical part contains calculations, creation of maps and representation of vertical cuts. The outcome is the sketch of the position and diagrammatical sketch of the existed locality and vertical cuts.

I perceive the thesis as the outcome of longer-term considerations over the relationship between architecture and music, as well as the concepts of genius loci, memory of place, or site-specific art. Thanks to the closer encounter with the Broumov landscape and the churches designed by the architects Kryštof and Kilián Ignác Dientzenhofer, located in it, these reflections were connected with the term Baroque. The work is an experiment exploring the diversity of contemporary musical approaches responding to unified task based on the principles of Baroque architecture.

The topic of this Dissertation is ``Application of geodetic methods of data collection to horizontal and vertical surveys of elements of the landscape in the Jenín water catchment area{\crqq}. Its aim was to make a detailed horizontal as well as vertical surveys of the site in question. The survey was carried out with the use of the tachymetric method. The coordinates of the points were specified in the S-JTSK system and in the Bpv altitude system. The entire site features a surface area of approximately 40 hectares. At first the reconnaissance of the terrain and of the existing point array was carried out in the entire area, the site was subsequently subjected to a detailed survey. The measurements were carried out with the use of the Leica TCR 407 power total station. The data was processed in the Groma, Atlas and MicroStation software. The result of the present Dissertation is the original document of the map at a scale of 1:1000.

In this thesis was elaborated the topic: Project and surveying of the network for planimetry and hight points in the area of the river Ostřice using several methods. It{\crq}s purpose was a reconnaissance of the part of a basin of Ostřice, assessment of existing point field, propose and complete the point network for planimetry in sufficient density for further surveying work in the area and survey of location and level by using geodetic methods and GPS. The reconnaissance of the area was conducted due to geodetic and levelling data of the points and maps. A network of 18 points of the detailed point network was built. I located nine of them by using a GPS method and a method of polygonal traverse. The electronic total station Leica TC 407 was used for the point survey by the method of polygonal traverse, for the GPS method was used a GPS apparatus Trimble 4600LS. Altitude of the points was determined by the method of technical levelling. For the altitude determination was used a Topcon AT {--} 24A levelling device.

Conselho Nacional de Desenvolvimento Científico e Tecnológico / The skin is the protection, thermoregulation, and control of water loss from the body. When there is continuity injury in this tissue, any kind of trauma can alter its functions. The healing process depends on factors such as location and size of the lesion, age and systemic conditions of the patient and the surgical technique used to repair it. Attempts to intervene in healing dates back to antiquity, when it was already recognized the importance of protecting the wounds to avoid complications in the process. Some resources are used as adjuvants in the healing process in order to obtain better results. For this experiment, we used 20 New Zealand White rabbits (Oryctolagus cuniculus). The animals were randomly divided into four groups of five animals each, in which we performed a skin wound 4cm ². In group A, animals received no treatment, group B was treated with transplantation of autologous mesenchymal stem cells, group C was treated with local application of therapeutic ultrasound, and group D laser was applied on site. The wounds were assessed at 7, 14 and 21 days postoperatively by measuring the area and biopsy. At the end of the study it was observed a statistical difference the group treated with cells in the healing process between groups. / A pele faz a proteção, termorregulação e controle da perda de água do corpo. Quando há lesão de continuidade neste tecido qualquer que seja o tipo de trauma pode alterar suas funções. O processo de cicatrização depende de alguns fatores como: local e tamanho da lesão, idade e condições sistêmicas do paciente bem como da técnica cirúrgica empregada para sua correção. As tentativas de intervir na cicatrização remontam à antiguidade, quando já se reconhecia a importância de proteger as feridas para evitar complicações neste processo. Alguns recursos são usados como adjuvantes no processo cicatricial a fim de se obter melhor resultado. Os objetivos foram avaliar a cicatrização das feridas temporal e histologicamente. Para a realização deste experimento, foram utilizados 20 coelhos (Oryctolagus cuniculus) da raça Nova Zelândia Branco. Os animais foram distribuídos aleatoriamente em quatro grupos de cinco animais cada, nos quais foi realizada uma ferida cutânea de 4cm² de área. No grupo A os animais não receberam nenhum tipo de tratamento, o grupo B foi tratado com transplante autógeno de células-tronco mesenquimais, o grupo C foi tratado com aplicação local de ultrassom terapêutico; e o grupo D foi aplicado laser no local. As feridas foram avaliadas aos 7, 14 e 21 dias de pós-operatório pela medida da área e biópsia. Ao final do estudo foi possível observar diferença estatística do grupo tratado com células no processo de cicatrização entre os grupos.

Foram avaliados os efeitos do ultra-som pulsado de baixa intensidade sobre a cicatrização de lesão cutânea produzida na região dorsal de ratos. Utilizamos 60 ratos machos (Wistar, peso médio de 300g) divididos em dois grupos de acordo com o tratamento, sendo: 1) irradiação simulada (controle); 2) irradiação efetiva (irradiado) Freqüência fundamental de 1,5MHz, freqüência de repetição de pulsos de 1KHz, largura de pulso de 200 µs, intensidade de 30mW/cm2 (SATA), 10 minutos de aplicação em dias alternados). Cada grupo foi subdividido em três grupos, de acordo com o período de irradiação ultrasônica; 3, 7 e 14 dias, e a cicatrização foi avaliada através de análise planimétrica. Aumento significante (p<0,05) da área cicatrizada foi observado no Grupo 2 (141,88±18,50 mm2) em relação ao Grupo 1 (117,38±15,14 mm2), no 14o dia. Não foram observadas diferenças entre os grupos nos outros tempos experimentais estudados. Concluiuse que o ultra-som pulsado de baixa intensidade não apresenta efeitos deletérios e estimula moderadamente a cicatrização cutânea por segunda intenção em condições experimentais, com potencial para aplicação clínica em humanos. Ainda, a planimetria, como método de companhamento da evolução da lesão cutânea, mostrou-se adequada e eficaz. / The effects of low intensity pulsed ultrasound irradiation on the secondary healing of a round shaped (1 cm in diameter) total skin lesion, produced on the dorsal region of rats, were studied. Sixty male Wistar rats weighing 300 g on average were used and divided into two groups of 30 animals each, according to treatment: Group 1, simulated irradiation (control); Group 2, effective irradiation (irradiated). 1.5 MHz fundamental frequency, 1 KHz pulse repetition frequency, 200 µs pulse width, 30mW/cm2 intensity (SATA), 10 minutes application in alternate days). Each group was divided into three subgroups: 3, 7 and 14 days, according to the postoperative period of ultrasound irradiation, and healing was evaluated by means of planimetry. The healed area was significantly increased (p<0.05) in Group 2 (141.88±18.50 mm2) as compared to Group 1 (117.38±15.14 mm2) on the 14th day. No differences were observed between subgroups for the other experimental periods. The author conclude that low intensity pulsed ultrasound irradiation presented virtually no deleterious effect and moderately stimulated secondary healing of total skin lesions in the experimental conditions of this investigation, with potential for clinical application in similar situations in humans. Also, planimetry showed to be effective method in evaluating the healing of skin lesions.

The subject of my diploma project has been detailed surveying of planimetry and altitude points in the part of the area of the river Ostřice as control points in order to watch long time changes of the landscape. Mapping work carried out in the surroundings of the village land Hodňov in the cadastral territory of Horni Plana 5-2 in the approximate area of 27 hectare. The aim of this work was the creation of planimetric and hypsographic plan at a scale of 1:500, which was based on field reconnaissance and the current point field, the proposal stabilization and surveying detailed points, a detailed surveying situation, computational work and graphic processing. The alignment of interest locations were used tacheometrical method. Height detailed and auxiliary points were determined trigonometric and situation were determined polar. For measurement purposes was used a total station Leica TCR 407 power. The coordinates of all points are identified in the system S-JTSK and height are identified in the system BPV.
