This paper, through the literature review, seeks to demonstrate the complementary activity developted by private entities such as Senar / AR-GO, on social assistance. The Social assistance and the support to the activities of health and social insurance are items that are part of the Principle of Human Dignity, bringing decent life condition and survival for those who have sufficient financial resources or not. The Dignity of the Human makes part of Human Rights, and its recognition is important to reflect about the modern conception of citizenship (Federal Constitution of 1988), citizenship that allowed the evolution of worker rights (Labour and Social Security) and its importance to society. These rights must be guaranteed by state entities, although there are a lot of government omission, which grows mainly in the rural population. The Social Security makes room in the Organic Law of Social Assistance to the inclusion of private initiatives, among them, the Health Field Program Senar / AR-GO was chosen as an example of private activity to illustrate the contribution of corporate welfare in the developed by state entities.
Esta dissertação, através de revisão bibliográfica, busca demonstrar o papel complementar desempenhado por entidades privadas, como o Senar/AR-GO, na assistência social. A Assistência Social e o amparo às atividades de Previdência Social e Saúde são itens que integram o Princípio da Dignidade Humana, trazendo condições dignas de vida e sobrevivência para àqueles que possuem ou não recursos financeiros suficientes. A Dignidade da Pessoa Humana faz parte dos Direitos Humanos, sendo o seu reconhecimento importante para tecer reflexões sobre a concepção moderna de Cidadania (Constituição Federal de 1988), cidadania essa que possibilitou a evolução dos direitos do trabalhador (Direito do Trabalho e Seguridade Social) e sua importância perante a sociedade. Esses direitos devem ser garantidos por entes estatais, porém existe muita omissão governamental, que se acentua, sobretudo, na população rural. A Seguridade Social abre espaço na Lei Orgânica da Assistência Social para a inserção de iniciativas privadas, dentre elas, o Programa Campo Saúde do Senar/AR-GO foi escolhido como exemplo de atividade privada para ilustrar a contribuição de pessoas jurídicas na assistência social desenvolvida pelos entes estatais.

U disertaciji je prikazano teorijsko i praktično istraživanje koje se odnosi na projektovanje, fabrikaciju i karakterizaciju heterogeno integrisanih induktivnih senzora za mjerenje sile, pritiska i pomjeraja. Cilj istraživanja doktorske disertacije je kombinovanje različitih tehnologija izrade i materijala, kako bi se projektovali senzori koji će biti konkurentni aktuelnim rešenjima, i koji bi se mogli koristiti za konkretne primjene. U okviru istraživanja, heterogenom integracijom su kombinovane prednosti tehnologije štampanih ploča (Printed Circuit Board - PCB), fleksibilne tehnologije i tehnologije niskotemperaturne zajedno-pečene keramike (Low Temperature Co-fired Ceramics – LTCC). Razvijena su tri prototipa senzora za mjerenje sile, pritiska i pomjeraja korišćenjem struktura sa induktorom i feritom u njegovoj blizini. Mjerenje realizovanih prototipova senzora vrši se bežično pomoću spregnutog antenskog namotaja. Na osnovu početnih rezultata ispitivanja, senzori su modifikovani u cilju poboljšanja i optimizovanja performansi. Projektovani senzori omogućavaju bežično mjerenje, jeftini su, kompaktni i jednostavni. Na osnovu teorijske analize, simulacija, eksperimetnalnih mjerenja, ustanovljena je ispravnost rada i primjenljivost realizovanih senzora.
In doctoral thesis theoretical and practical investigation on design, fabrication and characterisation of heterogenous integrated inductive sensors for measuring force, pressure and displacement are shown. The aim of the thesis is to investige the usage of different technologies and materials in order to design sensors which will be competitive to actual solutions and usable for specific aplications. Using heterogenous integraton, advantages of Printed Circuit Board technology (PCB), flexible and Low Temperature Co-fired Ceramics (LTCC) technologies are used. Three sensor prototypes for measuring force, pressure and displacement are developed using inductor and ferrite in its near proximity. Measurements of the realised sensor prototypes are wirelessly done using an external surrounding coil as an antenna. Based on the initial measuring results, sensors are redesigned in order to improve and optimize their performance. Projected sensors are low-cost, compact, simple, and enable wireless measurement. The proper operation and applicability of realized sensors are confirmed using theoretical analysis, simulation and experimental testing with presented results.

Abstract:

The thesis is focused on the design of a self-powered sensor for measurement of water flow rate and temperature in water pipelines. The key block of this thesis is the construction of an electric generator powered by excitation with turbulent flow. The generated voltage should power the sensor's circuits and allow water flow rate measurements. Throughout the development, three prototypes of generators powered by turbulent flow were created. Turbulences were not created by an insertion of a bluff body but by inner geometry of the pipeline elements. Maximum power of 10,66 uW was generated at flow rate of 8 m3/h. Afterwards, a prototype of water flow rate and temperature sensor was assembled. Energy self-sufficiency of the device at common flow rates was not achieved using the chosen procedure. The designed flow rate measurement method is suitable for an approximate flow rate estimation.

Abstract:

Recent studies have shown that only one in five Norwegian adults and elderly reach the national recommendation of 30 minutes of daily activity. Increasing the activity of the elderly is one of the main foci of Hagen Utvalget, a committee appointed by the Norwegian government to solve future challenges in care services. The report emphasizes on using technology to help solve such health problems. Using a sensor called the activPAL we are able to classify a patients activity into periods spent walking, standing and sedentary. Data gathered by the sensor is used to create visualizations illustrating the patients activity throughout a week. The question we aim to answer is: Which visualizations are most fitting to aid physiotherapists in interpreting and understanding accelerometer data from patients, in communication with patients and other healthcare workers? A prototype was created and reviewed in two focus groups with physiotherapists. The process was iterative and feedback from the first focus group was used to modify and improve the prototype before the second focus group. In addition to the prototype, scenarios for the use of the system and a set of functional and user experience requirements were created. The requirements and prototype form recommendations on how to create visualizations that aid physiotherapists in specific tasks. All of the participants of the focus groups were positive to the prototype presented and could see themselves using such a system in their work. The participants were also convinced that using such technology would improve the quality and effectiveness of their work.

Abstract:

Hydrogen has been for some time discussed as a successor to fossil fuels whose stocks are constantly running low. One of the crucial requirements for the possible usage of hydrogen as an energy carrier is our ability of reliable detection. In context with development of organic electronics there occurred a possibility to use derivatives of diketopyrrolopyrroles as sensing materials of hydrogen sensors. Derivatives of diketopyrrolopyrrole are organic pigments that behave as semiconductors. Their analogues with pyridyl side group are due to free electron pairs of nitrogen atoms sensitive to hydrogen. The problem of organic N-type semiconductors is in general their instability on the air. This thesis is focused on testing of hydrogen sensors with active layer made from derivatives of diketopyrrolopyrrole and judging their stability on the air.

Abstract:

In area of Smart-home control, there are requirements for miniaturisation, security and advanced control logic of individual member of system at present. One of the challenges is the way of data collecting from terminal nodes and data processing, including their distribution to the others nodes of Smart-home. The goal of this thesis is to design and to produce Smart-home control node, which will be a gateway between sensoric net and database and will be developed and produced on embedded system with speci c HW boards. Functionality of this gateway should include error states, e.g. should cache sensor messages when the connection between gateway and server interrupts, or take care about time synchronising. The thesis describes theoretical side of gateway design and also practical side of programming and producing SW for the gateway in Smart-home system.

Abstract:

The thesis deals with integral and distributed optical fiber sensors of electric current. In the area of integral sensors the analysis is performed by Jones matrix calculus and the simultaneous influence of induced circular and undesired linear birefringence using an ortho-conjugation retroreflector. Furthermore, the proposed conjugation loop variant using half-wave phase retarders is analyzed. The theoretical conclusions are confirmed by simulation and experimental measurement. In the field of distributed fiber optic sensors, analysis and simulation for the detection of plasma currents in thermonuclear fusion reactors, based on the POTDR technique, is performed. An improvement procedure is proposed for circular-shaped vacuum vessel reactors. Plasma current detection procedure in divertor-type reactors have been newly designed and simulated to investigate the effect of the OTDR detector noise on plasma current detection accuracy.
