Förändringsprogram i hälso- och sjukvården : Nätverkskonstruktioner som möjliggör och försvårar införandet av lean

Within the public sector great change efforts are currently made to meet future challenges. In the area of health care, change initiatives are implemented to enhance quality and efficiency. To this end, a lean change programme is being widely introduced in Sweden as well as internationally. The overriding aim of this study is to increase knowledge of what happens when change programmes, CP, such as lean are implemented in a healthcare organisation, HCO. Previous research has shown that the main obstacle to implementing CP in HCO:s is their complexity. However, the complexity has often been reduced, as different factors such as management, professions, organisation and control have been studied separately. To fully capture the complexity of the HCO the Actor Network Theory, ANT, was used in this study. In line with ANT, introducing lean can be described in terms of a translation process in which human and non-human actors are woven into a network. This approach allows for the incorporation of various factors in the study of a change process in a complex organisation. Drawing on ANT, this thesis explores how network constructions enable or impede change programmes. The approach is based on ethnographic monitoring of the implementation of lean in the Värmland county council public healthcare organisation. As a result of the holistic perspective, the study provides detailed descriptions of how complexity impacts on the implementation. It displays the relations enabling or impeding the implementation of CP and the methods actors use to establish and defend the relations. The contribution of the study is threefold. Empirically, the study monitors a HCO aiming to implement full-scale lean as philosophy, principle and tool. Methodologically, the study evaluates ANT as a methodological theory to study CP in a HCO. Finally, the domain-specific contribution of the study is its identification of the relations and methods that impact on lean deployment. 

Desenvolvimento de protótipo de aplicativo móvel em Android® para o controle e acompanhamento nutricional da saúde óssea em mulheres menopáusicas

Following a drop in estrogen in the period of menopause some women begin to lose bone mass more than 1% per year reaching the end of five years with loss greater than 25%. In this regard, factors such as older age, low calcium intake and premature menopause favor the onset of osteoporosis. Preventive methods such as nutritional counseling to a proper diet and the support of technology through applications that assess dietary intake are essential. Thus, this study aimed to develop an application for Android® platform focused on the evaluation of nutritional and organic conditions involved in bone health and risks for developing osteoporosis in postmenopausal women. To achieve this goal we proceeded to a study of 72 women aged 46-79 years, from the physical exercise for bone health of the Laboratory for Research in Biochemistry and Densitometry the Federal Technological University of Paraná program. Data were collected in the second half of 2014 through tests Bone Densitometry and Body Composition, Blood Tests, Anthropometric data and Nutrition Assessment. The study included women with a current diagnosis of osteopenia or osteoporosis primary, aged more than 45 years postmenopausal. For the assessment of bone mineral density and body composition used the device Absorptiometry Dual Energy X-ray (DXA) brand Hologic Discovery TM Model A. For anthropometric assessment was included to body mass, height, abdominal circumference, Waist circumference and hip circumference. The instrument for assessing food consumption was used Recall 24 hours a day (24HR). The estimated intake of energy and nutrients was carried from the tabulation of the food eaten in the Software Diet Pro 4®. In a sub sample of 30 women with osteopenia / osteoporosis serum calcium and alkaline phosphatase tests were performed. The results demonstrated a group of women (n = 30) average calcium intake of 570mg / day (± 340). The analysis showed a mean serum calcium within the normal range (10,20mg / dl ± 0.32) and average values and slightly increased alkaline phosphatase (105.40 U / L ± 23.70). Furthermore, there was a significant correlation between the consumption of protein and the optimal daily intake of calcium (0.375 p-value 0.05). Based on these findings, we developed an application early stage in Android® platform operating system Google®, being called OsteoNutri. We chose to use Java Eclipse® where it was executed Android® version of the project; choice of application icons and setting the visual editor for building the application layouts. The DroidDraw® was used for development of the three application GUIs. For practical tests we used a cell compatible with the version that was created (4.4 or higher). The prototype was developed in conjunction with the Group and Instrumentation Applications Development (GDAI) of the Federal Technological University of Paraná. So this application can be considered an important tool in dietary control, allowing closer control consumption of calcium and dietary proteins.

Professional development programs in health promotion : tools and processes to favor new practices

Developing innovative interventions that are in sync with a health promotion paradigm often represents a challenge for professionals working in local public health organizations. Thus, it is critical to have both professional development programs that favor new practices and tools to examine these practices. In this case study, we analyze the health promotion approach used in a pilot intervention addressing children’s vulnerability that was developed and carried out by participants enrolled in a public health professional development program. More specifically, we use a modified version of Guichard and Ridde’s (Une grille d’analyse des actions pour lutter contre les inégalités sociales de santé. In Potvin, L., Moquet, M.-J. and Jones, C. M. (eds), Réduire les Inégalités Sociales en Santé. INPES, Saint-Denis Cedex, pp. 297– 312, 2010) analytical grid to assess deductively the program participants’ use of health promotion practices in the analysis and planning, implementation, evaluation, sustainability and empowerment phases of the pilot intervention. We also seek evidence of practices involving (empowerment, participation, equity, holism, an ecological approach, intersectorality and sustainability) in the intervention. The results are mixed: our findings reveal evidence of the application of several dimensions of health promotion (equity, holism, an ecological approach, intersectorality and sustainability), but also a lack of integration of two key dimensions; that is, empowerment and participation, during various phases of the pilot intervention. These results show that the professional development program is associated with the adoption of a pilot intervention integrating multiple but not all dimensions of health promotion. We make recommendations to facilitate a more complete integration. This research also shows that the Guichard and Ridde grid proves to be a thorough instrument to document the practices of participants.

Smart Textile Sensors for Healthcare Monitoring

Wearable electronic textiles are an emerging research field playing a pivotal role among several different technological areas such as sensing, communication, clothing, health monitoring, information technology, and microsystems. The possibility to realise a fully-textile platform, endowed with various sensors directly realised with textile fibres and fabric, represents a new challenge for the entire research community. Among several high-performing materials, the intrinsically conductive poly(3,4-ethylenedioxythiophene) (PEDOT), doped with poly(styrenesulfonic acid) (PSS), or PEDOT:PSS, is one of the most representative and utilised, having an excellent chemical and thermal stability, as well as reversible doping state and high conductivity. This work relies on PEDOT:PSS combined with sensible materials to design, realise, and develop textile chemical and physical sensors. In particular, chloride concentration and pH level sensors in human sweat for continuous monitoring of the wearer's hydration status and stress level are reported. Additionally, a prototype smart bandage detecting the moisture level and pH value of a bed wound to allow the remote monitoring of the healing process of severe and chronic wounds is described. Physical sensors used to monitor the pressure distribution for rehabilitation, workplace safety, or sport tracking are also presented together with a novel fully-textile device able to measure the incident X-ray dose for medical or security applications where thin, comfortable, and flexible features are essential. Finally, a proof-of-concept for an organic-inorganic textile thermoelectric generator that harvests energy directly from body heat has been proposed. Though further efforts must be dedicated to overcome issues such as durability, washability, power consumption, and large-scale production, the novel, versatile, and widely encompassing area of electronic textiles is a promising protagonist in the upcoming technological revolution.

Rede de atenção à saúde mental de base comunitária: a experiência de Santo André

Os distúrbios psiquiátricos constituem um grave problema de saúde pública. Por muitos anos, a única terapêutica disponível ao portador de transtornos mentais era a internação em hospitais psiquiátricos. Hoje a Organização Mundial de Saúde recomenda os serviços de base comunitária como modelo de tratamento em saúde mental. Assim, o objetivo é descrever as características de uma rede de atenção à saúde mental de base comunitária no município de Santo André, SP. Foi realizado um estudo retrospectivo do tipo descritivo, em dados secundários do período de 1987 a 2006. O estudo incidiu sobre o histórico, a infra-estrutura, os recursos humanos, a produção, as práticas e processos de trabalho dos serviços de saúde mental de Santo André. Foram analisados documentos do Programa Municipal de Saúde Mental, da Secretaria Municipal de Saúde, da Prefeitura de Santo André, da Associação José Martins de Araújo Júnior-Organização Social De Volta Para Casa. A Secretaria Municipal de Saúde proveu meios para uma transformação dos serviços de saúde mental no período estudado, partindo de um atendimento exclusivamente manicomial para uma rede de serviços de saúde mental com modelo centrado na comunidade, focando a doença no aspecto psicossocial e com abordagem por equipe multiprofissional. Estas ações no município de Santo André foram corroborativas aos esforços da sociedade civil e o pleno desenvolvimento da mudança do modelo hospitalocêntrico

Piezoaeroelastic Modeling and Analysis of a Generator Wing with Continuous and Segmented Electrodes

Unmanned air vehicles (UAVs) and micro air vehicles (MAVs) constitute unique application platforms for vibration-based energy harvesting. Generating usable electrical energy during their mission has the important practical value of providing an additional energy source to run small electronic components. Electrical energy can be harvested from aeroelastic vibrations of lifting surfaces of UAVs and MAVs as they tend to have relatively flexible wings compared to their larger counterparts. In this work, an electromechanically coupled finite element model is combined with an unsteady aerodynamic model to develop a piezoaeroelastic model for airflow excitation of cantilevered plates representing wing-like structures. The electrical power output and the displacement of the wing tip are investigated for several airflow speeds and two different electrode configurations (continuous and segmented). Cancelation of electrical output occurs for typical coupled bending-torsion aeroelastic modes of a cantilevered generator wing when continuous electrodes are used. Torsional motions of the coupled modes become relatively significant when segmented electrodes are used, improving the broadband performance and altering the flutter speed. Although the focus is placed on the electrical power that can be harvested for a given airflow speed, shunt damping effect of piezoelectric power generation is also investigated for both electrode configurations.

An electromechanical finite element model for piezoelectric energy harvester plates

Vibration-based energy harvesting has been investigated by several researchers over the last decade. The goal in this research field is to power small electronic components by converting the waste vibration energy available in their environment into electrical energy. Recent literature shows that piezoelectric transduction has received the most attention for vibration-to-electricity conversion. In practice, cantilevered beams and plates with piezoceramic layers are employed as piezoelectric energy harvesters. The existing piezoelectric energy harvester models are beam-type lumped parameter, approximate distributed parameter and analytical distributed parameter solutions. However, aspect ratios of piezoelectric energy harvesters in several cases are plate-like and predicting the power output to general (symmetric and asymmetric) excitations requires a plate-type formulation which has not been covered in the energy harvesting literature. In this paper. an electromechanically coupled finite element (FE) plate model is presented for predicting the electrical power output of piezoelectric energy harvester plates. Generalized Hamilton`s principle for electroelastic bodies is reviewed and the FE model is derived based on the Kirchhoff plate assumptions as typical piezoelectric energy harvesters are thin structures. Presence of conductive electrodes is taken into account in the FE model. The predictions of the FE model are verified against the analytical solution for a unimorph cantilever and then against the experimental and analytical results of a bimorph cantilever with a tip mass reported in the literature. Finally, an optimization problem is solved where the aluminum wing spar of an unmanned air vehicle (UAV) is modified to obtain a generator spar by embedding piezoceramics for the maximum electrical power without exceeding a prescribed mass addition limit.

A social identity theory of leadership

A social identity theory of leadership is described that views leadership as a group process generated by social categorization and prototype-based depersonalization processes associated with social identity. Group identification, as self-categorization, constructs an intragroup prototypicality gradient that invests the most prototypical member with the appearance of having influence; the appearance arises because members cognitively and behaviorally conform to the prototype. The appearance of influence becomes a reality through depersonalized social attraction processes that make followers agree and comply with the leader's ideas and suggestions. Consensual social attraction also imbues the leader with apparent status and creates a status-based structural differentiation within the group into leader(s) and followers, which has characteristics of unequal status intergroup relations. In addition, a fundamental attribution process constructs a charismatic leadership personality for the leader, which further empowers the leader and sharpens the leader-follower status differential. Empirical support for the theory is reviewed and a range of implications discussed, including intergroup dimensions, uncertainty reduction and extremism, power, and pitfalls of prototype-based leadership.

Review and future directions in the modelling and control of continuous drum granulation

Many granulation plants operate well below design capacity, suffering from high recycle rates and even periodic instabilities. This behaviour cannot be fully predicted using the present models. The main objective of the paper is to provide an overview of the current status of model development for granulation processes and suggest future directions for research and development. The end-use of the models is focused on the optimal design and control of granulation plants using the improved predictions of process dynamics. The development of novel models involving mechanistically based structural switching methods is proposed in the paper. A number of guidelines are proposed for the selection of control relevant model structures. (C) 2002 Published by Elsevier Science B.V.

Communicating with the community about grieving: A description and review of the foundations of a broken leg analogy of grieving

With loss permeating the lives of all people throughout the entire life span and its potential for serious long-term deleterious effects, providing effective care for those experiencing situations of loss would be an important element of any preventive community-based mental health promotion approach. The low use of mental health services by those confronted with loss, and the lack of such services in many areas, makes it imperative to enhance the competency of the broader community to provide appropriate care during times of loss. Contributory to such care is a sound knowledge of the literature concerning loss and grieving. The broken leg analogy of grief presented in this article integrates the traditional and emerging grief theories and empirical evidence into an analogy of grieving that can be easily communicated to the general community, is relevant to many losses. and vet upholds the differing positions concerning grieving held by various schools of psychiatric thought.

Sentimento de discriminação em estudantes: prevalência e fatores associados

OBJETIVO: Estimar a prevalência e fatores associados ao sentimento de discriminação entre estudantes. MÉTODOS: Estudo transversal com amostra representativa de 1.170 escolares de um total de 2.282 matriculados na sétima série do ensino fundamental em escolas municipais de Gravataí (RS), em 2005. Os participantes foram selecionados por amostragem aleatória por conglomerado. Os dados foram obtidos com instrumentos auto-aplicados (Global School-based Student Health Survey, body shape questionnaire, classificação socioeconômica) preenchidos em sala de aula. Foi utilizada a regressão de Cox modificada para estudos transversais, segundo modelo hierarquizado em quatro etapas. RESULTADOS: A prevalência de sentimento de discriminação foi de 21,0%, mais prevalente entre: as meninas (RP=1,93, IC 95% 1,51;2,46); os que apresentaram absenteísmo escolar (RP=1,54, IC 95% 1,21;1,97); os que fizeram uso na vida de tabaco (RP=1,53, IC 95% 1,18;1,98); os preocupados com sua imagem corporal (RP=1,42, IC 95% 1,07;1,88); os com sentimento de solidão (RP=2,50, IC 95% 1,80;3,46) e tristeza (RP=1,29, IC 95% 1,02;1,62); os com dificuldade para dormir (RP:1,41, IC 95% 1,08;1,83); os com ideação suicida (RP=1,45, IC 95% 1,13;1,85) e os que sofreram algum tipo de injúria acidental (RP=1,56, IC 95% 1,23;1,97) ou intencional (RP=2,04, IC 95% 1,51;2,76). CONCLUSÕES: O sentimento de discriminação esteve associado ao sexo e à experiência com tabaco. Sua associação com fatores psicossociais indica a coexistência de situações adversas, como a insatisfação com a imagem corporal, sintomas depressivos e presença de injúrias. Esses resultados mostram a importância da atuação conjunta de professores e profissionais de saúde na identificação precoce desse sentimento, orientação e acompanhamento de jovens enfrentando essas situações.

On a reliable handoff procedure for supporting mobility in wireless sensor networks

Wireless sensor network (WSN) applications such as patients’ health monitoring in hospitals, location-aware ambient intelligence, industrial monitoring /maintenance or homeland security require the support of mobile nodes or node groups. In many of these applications, the lack of network connectivity is not admissible or should at least be time bounded, i.e. mobile nodes cannot be disconnected from the rest of the WSN for an undefined period of time. In this context, we aim at reliable and real-time mobility support in WSNs, for which appropriate handoff and rerouting decisions are mandatory. This paper1 drafts a mechanism and correspondent heuristics for taking reliable handoff decisions in WSNs. Fuzzy logic is used to incorporate the inherent imprecision and uncertainty of the physical quantities at stake.
