Viver livremente: trajetos e passagens de uma fuga do cuidado

Com o objetivo de compreender a busca por cuidado de uma pessoa portadora de transtorno mental em situação de comorbidade clínica, um trabalho de campo foi desenvolvido junto a uma usuária da rede de atenção em saúde do município do Rio de Janeiro-RJ. O atendimento desses casos é um desafio para o campo da saúde mental, pois demanda a elaboração de projetos terapêuticos que rompam com o dilema corpo/mente e promovam cuidado integral. A metodologia adotada foi a construção do itinerário terapêutico seguido pela usuária, tendo sido utilizadas as técnicas de observação participante, entrevista aberta e análise documental, ao longo de 6 meses do ano de 2013, envolvendo também os familiares e profissionais no estudo. Os resultados apontam que a usuária transitou tanto pelo Sistema Único de Saúde quanto pelo Sistema Único de Assistência Social ao longo do itinerário, tendo sido atendida em um centro de referência especializado, uma emergência médica, um hospital psiquiátrico, uma policlínica e uma clínica da família. Além disso, nos serviços de saúde foi descrita principalmente do ponto de vista biomédico, o alcoolismo e a demência predominando como índice de comorbidade psiquiátrica e a hanseníase como índice de comorbidade clínica, o transtorno mental esquizofrenia paranóide sendo o diagnóstico principal. A usuária apresentava-se aos profissionais como uma mãe que gostaria de viver em companhia dos filhos e ao mesmo tempo como alguém com vício de bebida forte, enquanto era considerada pelos familiares bêbada e maloqueira, habitando as ruas do centro da cidade do Rio de Janeiro há aproximadamente dez anos. Por meio da narrativa de uma parcela da trajetória de vida e de grande parte do itinerário terapêutico da usuária, nota-se trajetos entre serviços de saúde, casa e rua, bem como passagens marcadas pela vivência de que os profissionais de saúde manifestam asqueiro quando de sua presença. Com base nessa abordagem teórico-metodológica centrada na usuária, nota-se que os seus trajetos e passagens pela cidade e serviços de saúde repercutiram em seu cotidiano de uma forma que sua busca por cuidado converteu-se numa fuga do cuidado

A paternidade em famílias urbanas: uma análise da participação do pai na creche-escola e nos cuidados com o filho

Este estudo parte dos pressupostos de que o desenvolvimento humano em todos os seus aspectos depende de um outro social, de que a família é o primeiro ambiente socializador da criança, e suas práticas são essenciais para que a criança se desenvolva. Pressupõe-se também que: os bebês compartilham características universais, interações são constitutivas do desenvolvimento, o investimento parental é característica da espécie, e o formato que cada um desses aspectos assume está diretamente relacionado ao contexto sociocultural. A partir desses pressupostos pode-se pensar nas mudanças nos papéis sociais exigidas pelo sistema econômico da sociedade urbana ocidental, em que a mulher cada vez mais tem trabalhos remunerados, necessitando muitas vezes deixar os filhos em creches e levando o pai a ganhar espaço em relação aos cuidados com os filhos, inclusive tendo uma participação nestas instituições. Desta forma, o presente trabalho pretendeu investigar os diversos aspectos do envolvimento paterno com seus filhos, inclusive a sua participação na creche,, buscando compreendê-lo através da abordagem sociocultural. Fizeram parte da pesquisa empírica nesta tese três estudos distintos com pais e mães de crianças de 0 a 5 anos, incluindo entrevistas, aplicação do instrumento Estilo Paterno e análise da participação paterna em eventos e atividades escolares, com o intuito de investigar o nível de satisfação paterno e materno com o envolvimento do pai com os filhos e identificando em que aspectos essa participação é mais ou menos freqüente nos cuidados cotidianos, incluindo a escola. Os resultados encontrados indicam que, embora haja uma tendência dos pais em um maior engajamento nas atividades voltadas para o entretenimento com os filhos, estes se mostram cada vez mais disponíveis para o engajamento nas demais atividades diárias. Na creche há uma tendência de maior participação paterna quanto menor a idade do filho e enquanto não prevalecem os aspectos pedagógicos. Os pais participantes de uma forma geral estão satisfeitos com o seu exercício da paternidade, mas consideram que as mães, não só incentivam a sua participação, como desejam um maior engajamento dos pais. Ao término deste estudo podemos afirmar que, as famílias participantes desta amostra brasileira na cidade do Rio de Janeiro, tendem a não ter como prática o exercício da paternidade tradicional, porém ainda não vivem plenamente o exercício da paternidade não tradicional.

A matter of life and death: sociomateriality, information systems and critical care

Sociomateriality has been attracting growing attention in the Organization Studies and Information Systems literatures since 2007, with more than 140 journal articles now referring to the concept. Over 80 percent of these articles have been published since January 2011 and almost all cite the work of Orlikowski (2007, 2010; Orlikowski and Scott 2008) as the source of the concept. Only a few, however, address all of the notions that Orlikowski suggests are entailed in sociomateriality, namely materiality, inseparability, relationality, performativity, and practices, with many employing the concept quite selectively. The contribution of sociomateriality to these literatures is, therefore, still unclear. Drawing on evidence from an ongoing study of the adoption of a computer-based clinical information system in a hospital critical care unit, this paper explores whether the notions, individually and collectively, offer a distinctive and coherent account of the relationship between the social and the material that may be useful in Information Systems research. It is argued that if sociomateriality is to be more than simply a label for research employing a number of loosely related existing theoretical approaches, then studies employing the concept need to pay greater attention to the notions entailed in it and to differences in their interpretation.

Amorphous silicon thin film transistor biosensing system

Electronic systems are a very good platform for sensing biological signals for fast point-of-care diagnostics or threat detection. One of the solutions is the lab-on-a-chip integrated circuit (IC), which is low cost and high reliability, offering the possibility for label-free detection. In recent years, similar integrated biosensors based on the conventional complementary metal oxide semiconductor (CMOS) technology have been reported. However, post-fabrication processes are essential for all classes of CMOS biochips, requiring biocompatible electrode deposition and circuit encapsulation. In this work, we present an amorphous silicon (a-Si) thin film transistor (TFT) array based sensing approach, which greatly simplifies the fabrication procedures and even decreases the cost of the biosensor. The device contains several identical sensor pixels with amplifiers to boost the sensitivity. Ring oscillator and logic circuits are also integrated to achieve different measurement methodologies, including electro-analytical methods such as amperometric and cyclic voltammetric modes. The system also supports different operational modes. For example, depending on the required detection arrangement, a sample droplet could be placed on the sensing pads or the device could be immersed into the sample solution for real time in-situ measurement. The entire system is designed and fabricated using a low temperature TFT process that is compatible to plastic substrates. No additional processing is required prior to biological measurement. A Cr/Au double layer is used for the biological-electronic interface. The success of the TFT-based system used in this work will open new avenues for flexible label-free or low-cost disposable biosensors. © 2013 Materials Research Society.

Fiber Dispersion and Nonlinearity Influences on Transmissions of AM and FM Data Modulation Signals in Radio-Over-Fiber System

Transmission properties of data amplitude modulation (AM) and frequency modulation (FM) in radio-over-fiber (RoF) system are studied numerically. The influences of fiber dispersion and nonlinearity on different microwave modulation schemes, including double side band (DSB), single side band (SSB) and optical carrier suppression (OCS), are investigated and compared. The power penalties at the base station (BS) and the eye opening penalties of the recovered data at the end users are both calculated and analyzed. Numerical simulation results reveal that the power penalty of FM can be drastically decreased due to the larger modulation depth it can achieve than that of AM. The local spectrum broadening around subcarrier microwave frequency of AM due to fiber nonlinearity can also be eliminated with FM. It is demonstrated for the first time that the eye openings of the FM recovered data can be controlled by its modulation depths and the coding formats. Negative voltage encoding format was used to further decrease the RF frequency thus increase the fluctuation period considering their inverse relationship.

Research of Face Detection System Applied for Detecting Faces with Complex Background and Illumination

An effective face detection system used for detecting multi pose frontal face in gray images is presented. Image preprocessing approaches are applied to reduce the influence of the complex illumination. Eye-analog pairing and improved multiple related template matching are used to glancing and accurate face detecting, respectively. To shorten the time cost of detecting process, we employ prejudge rules in checking candidate image segments before template matching. Test by our own face database with complicated illumination and background, the system has high calculation speed and illumination independency, and obtains good experimental results.

G-quadruplex-based DNAzyme for sensitive mercury detection with the naked eye

Hg2+ is able to inhibit the peroxidase-like DNAzyme function of a T-containing G-quadruplex DNA via Hg2+-mediated T-T base pairs, which enables the visual detection of Hg2+ in the TMB-H2O2 reaction system with high selectivity and sensitivity.

Electrochemiluminescence of the Ru(bpy)(3)(2+)/S(2)O(8)(2-)system in purely aqueous solution at carbon paste electrode

The electrochemiluminescence (ECL) of the Ru(bgy)(3)(2-)/S2O82- system in purely aqueous solution at a carbon paste electrode can be clearly seen with the naked eye for Ru(bpy)(3)(2+) concentrations higher than 1 mmol L-1. The log-log plot of the emmitted light intensity vs. Ru(bpy)(3)(2+) concentration is linear over the region 10(-3)-10(-7) mol L-1 with a correlation coefficient of 0.997. The ECL intensity increases linearly with the S2O82- concentration from 10(-6) mol L-1 up to 0.3 mmol L-1 and drops off sharply at concentrations higher than 1 mmol L-1. In addition, a weak ECL signal was obtained when the potential was biased more negative than -0.6 V even in the absence of S2O82-.

A Self-initializing Eyebrow Tracker for Binary Switch Emulation

We designed the Eyebrow-Clicker, a camera-based human computer interface system that implements a new form of binary switch. When the user raises his or her eyebrows, the binary switch is activated and a selection command is issued. The Eyebrow-Clicker thus replaces the "click" functionality of a mouse. The system initializes itself by detecting the user's eyes and eyebrows, tracks these features at frame rate, and recovers in the event of errors. The initialization uses the natural blinking of the human eye to select suitable templates for tracking. Once execution has begun, a user therefore never has to restart the program or even touch the computer. In our experiments with human-computer interaction software, the system successfully determined 93% of the time when a user raised his eyebrows.

Real Time Eye Tracking and Blink Detection with USB Cameras

A human-computer interface (HCI) system designed for use by people with severe disabilities is presented. People that are severely paralyzed or afflicted with diseases such as ALS (Lou Gehrig's disease) or multiple sclerosis are unable to move or control any parts of their bodies except for their eyes. The system presented here detects the user's eye blinks and analyzes the pattern and duration of the blinks, using them to provide input to the computer in the form of a mouse click. After the automatic initialization of the system occurs from the processing of the user's involuntary eye blinks in the first few seconds of use, the eye is tracked in real time using correlation with an online template. If the user's depth changes significantly or rapid head movement occurs, the system is automatically reinitialized. There are no lighting requirements nor offline templates needed for the proper functioning of the system. The system works with inexpensive USB cameras and runs at a frame rate of 30 frames per second. Extensive experiments were conducted to determine both the system's accuracy in classifying voluntary and involuntary blinks, as well as the system's fitness in varying environment conditions, such as alternative camera placements and different lighting conditions. These experiments on eight test subjects yielded an overall detection accuracy of 95.3%.
