(Re)significando os projetos cuidativos da Enfermagem à luz das necessidades em saúde da população
Authors: Oliveira Maria Amélia de Campos
Published: September 2012

O conceito de necessidades é central no trabalho de Enfermagem. A Teoria das Necessidades Humanas Básicas, formulada por Wanda Horta, influenciou várias gerações de enfermeiras brasileiras e, possivelmente, ainda é a mais presente no ensino e na prática de Enfermagem no Brasil. Entretanto, há outras concepções de necessidades que podem iluminar o trabalho em saúde que, em geral, está organizado para responder a essas necessidades por meio da oferta de serviços padronizados, verticais e prescritivos. Ressignificar o cuidado em saúde e, em especial, os projetos cuidativos da Enfermagem à luz das necessidades em saúde da população requer adotar uma concepção de saúde e doença capaz de interligar aspectos individuais e coletivos.

Published: September 2012

Health related quality of life (HRQL) and survival are two important outcome measures in chronic diseases. This study aimed to compared HRQL in patients with different chronic diseases of immune system and normative data from the general Portuguese Population. It was selected 103 out-patients, by convenience, to complete SF-36v2. The lowest scores were found among measures for general health (41.0), vitality (47.5), bodily pain (51.0), mental health (56.4); women, except for role-physical, and patients with auto-immune diseases have had the worse scores on all assessed dimension of subjective health, when compared with normative data. Highest scores were obtained in the following scales: physical functioning (69.1), social functioning (66.9), role-emotional (64.9). Living with chronic immune disease have impact on HRQL and it can be expected that the Portuguese version of SF-36v2 provide valid and reliable HRQL data.
Contribuição para o estudo da influência da profundidade de trabalho do arado na produção agrícola
Authors: Leme Hugo de Almeida
Published: September 2012

A aradura é a principal das operações agrícolas para o desenvolvimento das diversas culturas. A sua importância é conhecida desde as mais remotas eras. Assim, os romanos já tinham sua teoria sobre aradura. Desta forma o arado, a mais antiga das máquinas agrícolas, foi sempre motivo de atenção dos agricultores, fabricantes e técnicos em mecânica agrícola. A sua evolução foi bastante grande. O estudo do arado sob o ponto de vista agrícola e econômico, para exata aplicação da máquina, nas diversas condições de solo, é de máximo interêsse para a mecânica agrícola. Assim sendo, para orientar a correta aplicação do arado, o que constitui a presente tese, foi experimentado num solo arenoso, de características mecânicas (areia total 75,7%, argila 13,5 e lôdo 10,8%) a diversas profundidades de aração, (5, 10, 15, 20, 25, 30cm), plantando nos mesmos, milho para verificar o efeito na produção. Num terceiro ano de experiência, foi realizada uma experiência a mais, isto é, uma subsolagem a 40 cm. Foi plantado milho nos canteiros assim trabalhados, e que eram repetidos em número de 4, porque o milho é uma cultura muito frequente e de fácil contrôle. As experiências com as diversas profundidades, demostraram que nestas condições de solo, à medida que aumenta a profundidade, aumenta também a produção. Do exposto, conclui-se pela experimentação que para esse solo é aconselhável: fazer o arado trabalhar a maior profundidade em que comumente é empregado até o limite de 25 cm, que foi o valor máximo examinado.

Authors: Weirich Neto Pedro H. , Justino Altair , Antunes Rodolfo K. , Fornari Allison J. , Garcia Luiz C.
Published: September 2012

O objetivo deste trabalho foi verificar se a cultura do milho é influenciada pelo manejo mecânico da aveia-preta dessecada antes de sua semeadura, pela utilização de rolo destorroador. Os tratamentos consistiram na semeadura do milho sob a matéria seca de aveia-preta dessecada sem manejo mecânico e rolada. O experimento foi realizado em quatro propriedades, duas na safra de 2007/2008 e as outras duas na safra de 2008/2009. O delineamento experimental adotado foi em blocos ao acaso, com 11 repetições, cujas parcelas possuíam 80 m² cada. Avaliaram-se a qualidade da semeadura e os componentes de rendimento. Conclui-se que o manejo mecânico da palha de aveia-preta antes da semeadura do milho pode elevar significativamente os espaçamentos falhos e reduzir significativamente os espaçamentos aceitáveis. Nas áreas experimentais, os tratamentos não afetaram os componentes de rendimento da cultura do milho, havendo apenas acréscimo no custo da produção.

Authors: Rodrigues Jeferson , Santos Silvia Maria Azevedo dos , Spricigo Jonas Salomão
Published: September 2012

Investigamos como se materializa o ensino do cuidado de enfermagem em saúde mental nos discursos dos docentes que ministram os conteúdos de enfermagem psiquiátrica e/ou saúde mental nos quatro cursos de graduação em enfermagem mais antigos do Estado de Santa Catarina, sendo um deles público, e três, privados. O período de coleta dos dados foi de março a maio de 2010. Utilizamos a pesquisa qualitativa, do tipo descritiva e exploratória, tendo como técnica de coleta de dados, grupos de discussão. A perspectiva hermenêutico-dialética possibilitou a análise dos dados. Nos resultados, evidenciamos nos discursos docentes a ausência do paradigma de atenção psicossocial e de um ensino baseado na psicopatologia. Concluímos que o ensino do cuidado de enfermagem em saúde mental requer um referencial teórico baseado em paradigmas coerentes com a realidade local e a do Sistema Único de Saúde.
Bases biológicas e evidências epidemiológicas da contribuição do crescimento fetal e pós-natal na composição corporal: uma revisão
Authors: Gonçalves Fabiana Cristina Lima da Silva Pastich , Amorim Rosemary de Jesus Machado , Costa Suzana Maria Ramos , Lima Marilia de Carvalho
Published: September 2012

OBJETIVOS: apresentar as bases biológicas e evidências epidemiológicas do crescimento fetal e pós-natal relacionadas ao tamanho e composição corporal. MÉTODOS: a busca de artigos publicados nos últimos 15 anos foi realizada nas bases de dados Lilacs, SciELO, Medline através dos descritores: crescimento, restrição do crescimento fetal, baixo peso ao nascer, aceleração compensatória do crescimento, composição corporal, índice de massa corporal e hormônios. Os estudos foram selecionados de acordo com a pertinência às evidências a serem analisadas. RESULTADOS: os artigos apontam para a influência da restrição do crescimento intraútero na supressão da termogênese e regulação hormonal, que por sua vez interferem no ganho de peso após o nascimento, e explicam como ambos os processos, restrição do crescimento fetal e rápido ganho de peso pós-natal, influenciam as medidas corporais em fases posteriores da vida, com consequências que poderão afetar gerações. CONCLUSÕES: o crescimento fetal influencia o padrão de crescimento pós-natal devido a diversos fatores relacionados à regulação hormonal, porém existe ainda uma lacuna sobre a contribuição da somação entre crescimento fetal e pós-natal no tamanho e composição corporal em fases posteriores da vida.
Semi-Analytical Modeling of Steam-Solvent Gravity Drainage of Heavy Oil and Bitumen, Part 1: Enhanced Flow Rate at Mobile Zone
Authors: Faradonbeh M. Rabiei , Harding T. G. , Abedi J.
Published: September 2012

With increasing world demand for energy, more attention has been given to the exploitation of the huge resources present in the form of heavy oil and bitumen. Although thermal methods such as steam assisted gravity drainage (SAGD) are very successful in recovering heavy oil and bitumen, the low thermal efficiency of the process and the high level of greenhouse gas emissions and water usage remain major concerns.

Co-injection of solvent with steam has shown to be promising in enhancing oil rates as well as in reduction of energy and water consumption with lower environmental impacts. In hybrid steam-solvent methods, there is a balance between the solubility of the solvent and its ability to reduce bitumen viscosity, and the viscosity reduction due to temperature increase. Therefore, proper selection of the solvent for the operating conditions is key to improving the overall efficiency of the steam- solvent process over the steam-only method.

In this study, enhancement of the oil flow rate in the hybrid steam-solvent process is investigated using steady state temperature and unsteady state concentration distribution ahead of the interface with different operational parameters. The Integral Method is employed for prediction of solvent distributions, and the viscosity variation in the mobile zone is determined using the Shu (1984) correlation. The results show that the fractional increase in oil flow rate depends on type and mole fraction of the solvent in the steam chamber. It is also observed that large values of mechanical dispersivity factor enhances oil rate significantly; and drainage rate increases linearly with operating pressure.

The results can be used to find the optimum solvent candidate and the injection strategy to maximize the flow rate of the Expanding Solvent SAGD process. This analysis can also be applied for a mixture of solvents based on available experimental data.

Making a difference by doing applied qualitative research in education: Three case studies
Authors: Masaryk Radomír , Sokolová Lenka
Published: September 2012

The paper explores the possibilities of using applied qualitative research to help to achieve changes in the context of education. It presents three case studies: an evaluation of an educational software package which may be implemented nationally; an assessment of the impact of a 1:1 Technology Rich Learning Environment experimental project conducted in two Slovak elementary schools; and international comparative research on the curricula of psychology courses in secondary schools. The authors ask three questions: 1. does qualitative research have the potential/resources/capacity to guide us in the process of making policy related decisions? 2. Does it have enough credibility in the eyes of the consumers—whether these are decision-makers themselves or a wider community that often plays a role in public decisions? 3. Could this type of work still count as academic inquiry? The discussion evolves around the reflection of the position of researchers in this type of research design, and the authors conclude that applied qualitative research could be the source of solid evidence for making decisions related to education—although this evidence is different to that provided by quantitative research.
The Romani language in the Slovak educational system
Authors: Gažovičová Tina
Published: September 2012

The paper analyses the use of the Romani language in the Slovak educational system. It focuses on the informal use of Romani in schools, as about 10% of all pupils speak Romani as their mother tongue but there are no schools that use Romani as the language of instruction. The theoretical framework draws mainly on the work of P. Bourdieu and S. May on the symbolic power of language. The empirical chapter is based on qualitative data collected at ten primary schools in different parts of Slovakia, as well as interviews with decision makers and experts. On the basis of the empirical research, three questions are posed. (1) Is Romani used in schools and if so how? (2) What attitudes do school staff have on the use of Romani? (3) Is the theory of Stephen May applicable to Slovakia and is Romani perceived to have merely sentimental value while Slovak is considered to have instrumental value? The article concludes that the perceived value of Romani in Slovakia is very low. From the point of view of school staff, it has no instrumental value and is perceived as a barrier rather than a benefit.
“The Austrians were surprised that I didn’t speak German”: The role of language in Czech-Austrian relations
Authors: Petrjánošová Magda , Graf Sylvie
Published: September 2012

Respondents from Austria (N = 146) and the Czech Republic (N = 165) noted down their experiences with people from their neighbouring country and their attitudes to their own country and the neighbouring nation on feeling thermometers. The quantitative content analysis and qualitative critical discourse-inspired analysis of the open statements focused on the role of language in the construction of Czech-Austrian relations. Using qualitative analysis we enquired as to which themes were intertwined with the topic of language, and as to the ways in which the participants perceived themselves, the Others, behind the border, and the relations between the two sides. We looked not only into what participants said but also how they said it. Using statistical analysis we tested the link between language-related topics in the descriptions of intergroup contact and the evaluation of the neighbouring nation as a whole. Throughout the article we compare the findings obtained by the two kinds of analysis and comment on (dis)agreement as well as on the (dis)advantages of both approaches.
Qualitative research and scientific knowledge: Social science in post-totalitarian academia
Authors: Podoba Juraj
Published: September 2012

The paper presents a critical analysis of the current state of qualitative research approaches in the social sciences and humanities within Slovak academic institutions. The author has been inspired by the metaphor of academic “barbaricum”. This analytical category is based on a model of the relationship between core and periphery, which has no clear function or organisational logic. From the scientific point of view, the core/centre should produce and innovate the theory, whereas the periphery should apply it. In Slovakia—contrary to the situation in Western academia—, the last two decades have seen a growth in the numbers of academic institutions dealing with the humanities (and partly with the social sciences), and stagnation in qualitative social research. The author suggests that if the Slovak social sciences aspire is to becoming part of the so-called European academic space, then this will certainly not be possible without much stronger and extensive support for social research based on qualitative approaches and methods.
Should we sacrifice embryos to cure people?
Authors: Lara Francisco
Published: September 2012

Medical stem cell research is currently the cause of much moral controversy. Those who would confer the same moral status to embryos as we do to humans consider that harvesting such embryonic cells entails sacrificing embryos. In this paper, the author analyses critically the arguments given for such a perspective. Finally, a theory of moral status is outlined that coherently and plausibly supports the use of embryonic stem cells in therapeutic research.
Comparison of Reliability, Validity, and Responsiveness of the Mini-BESTest and Berg Balance Scale in Patients With Balance Disorders
Authors: Godi Marco , Franchignoni Franco , Caligari Marco , Giordano Andrea , Turcato Anna Maria , Nardone Antonio
Published: September 2012

Background

Recently, a new tool for assessing dynamic balance impairments has been presented: the 14-item Mini-BESTest.

Objective

The aim of this study was to compare the psychometric performance of the Mini-BESTest and the Berg Balance Scale (BBS).

Design

A prospective, single-group, observational design was used in the study.

Methods

Ninety-three participants (mean age=66.2 years, SD=13.2; 53 women, 40 men) with balance deficits were recruited. Interrater (3 raters) and test-retest (1–3 days) reliability were calculated using intraclass correlation coefficients (ICCs). Responsiveness and minimal important change were assessed (after 10 sessions of physical therapy) using both distribution-based and anchor-based methods (external criterion: the 15-point Global Rating of Change [GRC] scale).

Results

At baseline, neither floor effects nor ceiling effects were found in either the Mini-BESTest or the BBS. After treatment, the maximum score was found in 12 participants (12.9%) with BBS and in 2 participants (2.1%) with Mini-BESTest. Test-retest reliability for total scores was significantly higher for the Mini-BESTest (ICC=.96) than for the BBS (ICC=.92), whereas interrater reliability was similar (ICC=.98 versus .97, respectively). The standard error of measurement (SEM) was 1.26 and the minimum detectable change at the 95% confidence level (MDC95) was 3.5 points for Mini-BESTest, whereas the SEM was 2.18 and the MDC95 was 6.2 points for the BBS. In receiver operating characteristic curves, the area under the curve was 0.92 for the Mini-BESTest and 0.91 for the BBS. The best minimal important change (MIC) was 4 points for the Mini-BESTest and 7 points for the BBS. After treatment, 38 participants evaluated with the Mini-BESTest and only 23 participants evaluated with the BBS (out of the 40 participants who had a GRC score of ≥3.5) showed a score change equal to or greater than the MIC values.

Limitations

The consecutive sampling method drawn from a single rehabilitation facility and the intrinsic weakness of the GRC for calculating MIC values were limitations of the study.

Conclusions

The 2 scales behave similarly, but the Mini-BESTest appears to have a lower ceiling effect, slightly higher reliability levels, and greater accuracy in classifying individual patients who show significant improvement in balance function.
SENSITIVITY ANALYSIS OF TANGENTIAL DIGGING FORCES OF THE BUCKET WHEEL EXCAVATOR SCHRS 1320 FOR DIFFERENT TERRACES
Authors: Gottvald Jakub , Kala Zdenek
Published: September 2012

Researches in the field of economy of control of mining processes of minerals are continually met with a number of unsolved and newly arising problems. New deposits of brown coal are located at greater depths than before and are more difficult to mine. Problems in the field of rock mining stem from the greater diversity of rocks in mining, and it results in more difficult mining conditions. On the other hand, even greater demands are made to decrease the economic demand of mining. Current research is aimed at the most optimal utilization of energy provided on the bucket wheel of excavators, such that the energy demand of the mining process decreases, whilst preserving maximum performance. These requirements place greater demands on the precision of planning of mining and maximum economic efficiency. The presented article illustrates the possibilities of the utilization of Sobol sensitivity analysis during the investigation of the influence of the parameters of mining processes on tangential digging forces. Analyses are carried out for the mining process of bucket wheel excavator SchRs 1320. For purposes of the study, detailed measurements of operational parameters were performed on the excavator during a whole work cycle.
RISK MANAGEMENT PRACTICE IN CHINA'S PUBLIC-PRIVATE PARTNERSHIP PROJECTS
Authors: Ke Yongjian , Wang ShouQing , Chan Albert P. C.
Published: September 2012

Project risks were not properly managed in the many past Public-Private Partnership (PPP) projects in China. Although numerous research studies have been conducted on risk management in China's PPP projects, the realization of risk management in China's construction industry especially in PPP projects with high risk exposure and complicated contract structure has hitherto not been well studied. This paper therefore attempted to examine the current use of risk management in China's PPP projects by an empirical survey. The results indicated that the use of risk management was inadequate; qualitative risk analysis methods were preferred to quantitative and semi-quantitative methods; risk management usage in the execution was found to be much higher than in the planning, conceptual or termination stage; interviewees were unfamiliar with most of the risk identification and assessment tools. All above could be partly due to the project nature, but more fundamentally due to the local industrial culture. The absence of risk management culture was found to be the dominant factor which limited the implementation of risk management in practice. Recommendations to alleviate the difficulties of risk management were thereafter provided in this paper.

Défendre le défenseur de l'ennemi public. L'affaire Croissant
Authors: Israël Liora
Published: September 2012

Résumé L’affaire Croissant constitue un moment décisif, bien qu’aujourd’hui largement méconnu, de l’histoire politique des années 1970. Avocat à Stuttgart, Klaus Croissant avait une clientèle composée majoritairement de militants, notamment des membres de la Fraction Armée Rouge d’Andreas Baader. Croissant fut accusé par les autorités allemandes d’être le complice des activités terroristes de ses clients, à la fois en mettant à leur disposition depuis son cabinet certaines facilités matérielles et surtout en organisant en prison des formes d’échange et de communication leur ayant en particulier permis de mener des grèves de la faim coordonnées. En butte à des poursuites, puis à différentes sanctions professionnelles (dont l’interdiction de représenter ses clients lors du procès de Stammheim), Klaus Croissant choisit en juillet 1977 de quitter son pays et de demander l’asile politique en France. C’est à ce moment de l’affaire que nous choisirons de nous intéresser, en centrant l’attention sur la mobilisation qui s’est alors développée contre la demande d’extradition formulée par la RFA, finalement satisfaite le 16 novembre 1977. Révélateur à la fois des relations complexes de la gauche à l’histoire contemporaine allemande et des enjeux pour les juristes de la « défense de la défense », l’affaire Croissant est un exemple qui permet de mettre en lumière les enjeux et les tensions propres à l’assimilation, en démocratie, de la défense de terroristes à celle du terrorisme.

New Fuzzy Similarity Measure for Restricted Mobile Networks
Authors: Chen Wen Can , Liu Xiao Dong
Published: September 2012

Similarity-based search has been a hot research topic for a long history, which is widely used in many applications. The large scale Restricted Floating Sensor (RFS) network is an important mod-el in offshore data collection [1]. Due to the mobility and the large number of sensors, improved techniques are needed to deal with uncertainty and mass queries. As a theoretical basis, this paper constructs a new fuzzy similarity measure based on distance. With examples we illustrate that many common similarity functions can be constructed from these measures. From [2] we know our work over distance and similarity is a reasonable generalization and extension of other Fuzzy Sets. This work provides a theoretical guidance for constructing a fuzzy query processing strategy for our RFS networks.
Restoration for Motion Blurred Images of Moving Objects
Authors: Zhou Gui Xiang
Published: September 2012

Image restoration plays an important role in transportation applications. This paper studies a motion blurred image processing method, which has good recovery effect. In this method, first the wiener filter is used for image restoration. Then, based on the error parameter analysis, the parameters of point spread function are estimated, and the noise parameter is estimated by using the probability and statistics method. Furthermore, the ringing effect is processed by using the smooth boundary method. Finally, experimental results show that the proposed method can restore the motion blurred images effectively and has strong robustness for the noise.
Researching on Speculating Algorithm Based on End-to-End Date in Wireless Sensor Networks
Authors: Ji Wen Li , Li Xiang Jun , Jiang Mei Ying
Published: September 2012

In this paper, we focus on how to gain network topology information of wireless sensor network (WSN) with higher accuracy. It is very important for Network planning and management. We propose a topology identification algorithm based on data fusion system in WSN. Firstly, based on the information of packet delay and/or packet loss, the algorithm got the collections of approximate ancestors of each node, according to the classification inference algorithm of graph theory. Secondly, it identifies parent-child relationship of the nodes by calculating the Hamming distance between the current node and approximate ancestors’ nodes; and infers the topology of the network layer by layer. The proposed algorithm doesn’t require support from internal nodes. It employs end-to-end measurements and does not incur any additional burden on the network.

Relevance Feedback Using RBF for Content Based Image Retrieval
Authors: Li Gui Zhi , Zhou Chang Sheng , Wang Wei , Liu Ya Hui
Published: September 2012

Conventional approaches to image retrieval are based on the assumption that relevant images are physically near the query image in some feature space. However, semantically related images are often scattered across several visual clusters. This leads to adapting multiple queries to represent a query in the feature space. Therefore, it is necessary to handle disjunctive queries in the feature space. In this paper, a new content-based image retrieval method with relevance feedback technique using RBF neural network learning is proposed. The method transfers the process of relevance feedback into a learning problem of RBF neural network. RBFNN can describe the distribution of positive feedback sample images in feature space with a set of neighboring clusters produced through constructing neural network, for accurately reflecting their semantic relevance. The performance of the method using RBFNN is evaluated on a database of 10,000 images. Experimental results demonstrate the effectiveness of the proposed method.

Supply Chain Network Equilibrium with Risk-Averse Members
Authors: Sun Hao , Zhang Gui Tao , Liu Ying
Published: September 2012

To obtain equilibrium patterns of a competitive supply chain network with stochastic demand, risk-averse channel members, production capacity constraints and price ceilings, we derived the optimization conditions of manufacturers, retailers and demand markets via variational inequality respectively, and then established the whole supply chain network equilibrium problem. Projection and contraction method was utilized to solve the model. Numerical examples were given to illustrate the impact of risk-averse degree of manufacturers and retailers on network equilibrium patterns in case of capacity constraints and price ceilings. The results show that under the same condition, the system profits decrease to a lower level when the manufacturers’ risk degree increase compared with retailers. The retailers bear more loss due to their positions in the supply chain.

Authors: Han Xue Song , Duan Yu Bo
Published: September 2012

This paper extends the results obtained for one-dimensional Markovian jump systems to investigate the problem of H∞model reduction for a class of linear discrete time 2D Markovian jump systems with state delays in Roesser model which is time-varying and mode-independent. The reduced-order model with the same randomly jumping parameters is proposed which can make the error systems stochastically stable with a prescribed H∞ performance. A sufficient condition in terms of linear matrix inequalitiesSubscript text(LMIs) plus matrix inverse constraints are derived for the existence of a solution to the reduced-order model problems. The cone complimentarity linearization (CCL) method is exploited to cast them into nonlinear minimization problems subject to LMI constraints. A numerical example is given to illustrate the design procedures.

Authors: Lu Gang , Wen Fu Shuan
Published: September 2012

In a pool-based single-buyer electricity market, a Generation Company (GENCO) is required to considering the decision risk when building the optimal bidding strategy due to the stochastic bidding behavior of the rivals. The optimal decision is to maximize the profit while minimizing the risk, however, they are contradicting targets. This paper proposes a new research framework about risk-constrained optimal bidding strategies based on the stochastic programming method, termed as balance programming between target and chance (BPTC). And this method can favor the GENCO to make the stochastic decision in a more rational, flexible, and applicable manner. A genetic algorithm with Monte Carlo simulation is employed to solve the programming model. The effectiveness of the proposed method is shown through a numerical test.
