O CUIDADO DE ENFERMAGEM À FAMÍLIA: UM ESTUDO BIBLIOGRÁFICO

SUMMARY: The objective of this study was to identify the scientific article about the care of nursing to the family, published in periodic of Brazilian nursing, index-linked article survey to the LILACS, in the period of 1993 the 2003, and to analyze them how much to the concept and composition of the families, systematization and proposals of action of nursing and formation and qualification of the authors. In the results we find in 10 years (1993-2003), 9 publications concerning nursing in family. Where we can find the predominance of works that focus the systematization and proposals of action, evidencing of a general form, a lack of studies in the area of nursing in family, where the Program of Health of the Family appears as principal source of promotion of care of nursing to the family and motivation for studies that approach this thematic one. All research had had as authorship nurses doctors, masters and specialists, which acted as professors. KEY WORDS: Assistance to the Family; Health of the Family and Nursing and Family.
Effect of yogic exercise on respiratory system in middle aged men

The aim of this paper is to study the effect of yogic exercise on respiratory system in middle aged men. The objective of the study is to assess respiratory parameter in both groups. For the study, we selected 90 healthy volunteers between age group 35 to 50. They were divided into 2 groups: 1) control group (45); and 2) study group (yoga) (45). Control group did not perform any exercise or yoga during 6 months period; whereas, study group performed yogic exercises and pranayama for 6 months under the supervision of yoga experts in yoga center. In both group respiratory rates, forced vital capacity (FVC) (L), forced expiratory volume (FEV1) (L), FEV1/FEC ratio and PEFR (L/S) were recorded at 0 and 6 months period. In control group, R/R, FVC(L), FEV1(L), PEFR(L/S) , FEV1/FVC ratio showed no significant changed at 0 and 6 month period; whereas, study group (yoga) showed decreased in R/R from 17.20 ± 1.17 to 13.93±0.75 at 6 months (p < 0.001); FVC increased from 2.85±0.26 to 3.03±0.23 at 6 months (p < 0.001). FEV1 increases from 2.31±0.25 to 2.50±0.23 at 6 months (p < 0.001). PEFR showed significant increased from 6.62±0.77 to 7.76±0.55 at 6 months (p < 0.001). FEV1/FEC (ratio %) increased from 81.06±3.18 to 82.25±3 at 6 months (p < 0.001). Weight andbody mass index (BMI) also showed significant decrease in study group (p<0.05). In conclusion, yogi exercises and pranayama done regularly at long term improve pulmonary function test. Key words: Yogic exercises, pulmonary function test, respiratory rate.
Minimizing Total Costs in One-Machine Scheduling

Suppose we have n jobs that arrive simultaneously to be processed on a continuously available machine that can handle only one job at a time. Each job has a fixed processing time and a cost function that is nondecreasing in its finishing time. We want to find a schedule that minimizes total costs. After reviewing the relevant work on this problem, we present a new algorithm for a general cost function. The algorithm is tested for the well known case of a weighted tardiness criterion.
Infinite Linear Programming in Games with Partial Information

An area of considerable recent research interest has involved the extension and modification of the basic model for two-person zero-sum game theory. One particular type of extension found in the literature involves the introduction of risk and uncertainty into the model by allowing the m × n payoff matrix A = aij to be a discrete random matrix that can assume a finite set of values. This paper considers both one-and two-person games and investigates the situation in which A is a discrete random matrix that can assume a countably infinite set of values {Ak}k=1∞. We assume that the players possess certain partial information about P, the distribution of A, in which case the game problems for players 1 and 2 can be reduced to programming equivalents. We prove minimax theorems for both semi-infinite and infinite games, and give some properties of optimal mixed strategies. The paper also develops some extensions of a theorem due to Caratheodory.
Interferon-α, but not the ABL-kinase inhibitor imatinib (STI571), induces expression of myeloblastin and a specific T-cell response in chronic myeloid leukemia

Chronic myeloid leukemia (CML) is a clonal disease of hematopoietic stem cells caused by a reciprocal translocation of the long arms of chromosomes 9 and 22. In human leukocyte antigen A*0201+ (HLA-A*0201+) individuals, response after interferon-α (IFN-α) was shown to be associated with the emergence of CML-specific cytotoxic T cells that recognize PR-1, a myeloblastin (MBN)– derived nonapeptide. In contrast, imatinib potently induces remissions from CML by specific inhibition of the ABL tyrosine kinase. Here, we explored molecular regulations associated with CML responses under different treatment forms using cDNA-array. Expression of MBN was found to be down-regulated in remission under imatinib therapy (0 of 7 MBN+ patients). In contrast, MBN transcription was readily detectable in the peripheral blood in 8 of 8 tested IFN-α patients in complete remission ( P = .0002). IFN-α–dependent MBN transcription was confirmed in vitro by stimulation of peripheral blood mononuclear cells (PBMCs) with IFN-α and by IFN-α–mediated activation of the MBN promoter in reporter gene assays. Finally, with the use of HLA-A*0201–restricted, MBN- specific tetrameric complexes, it was demonstrated that all of 4 IFN-α–treated patients (100%), but only 2 of 11 imatinib patients (19%), in complete hematological or cytogenetic remission developed MBN- specific cytotoxic T cells ( P = .011). Together, the induction of MBN expression by IFN-α, but not imatinib, may contribute to the specific ability of IFN-α to induce an MBN- specific T-cell response in CML patients. This also implies that the character of remissions achieved with either drug may not be equivalent and therefore a therapy modality combining IFN-α and imatinib may be most effective.
Supporting stock trading in multiple foreign markets: a multilingual news summarization approach

In today's world, plenty of textual news on stock markets written in different languages are available for traders, financial promoters, and private investors. However, their potential in supporting trading in multiple foreign markets is limited by the large volume of the textual corpora, which is practically unmanageable for manual inspection. Although, text mining and information retrieval techniques allow the automatic generation of interesting summaries from document collections, the study and application of multilingual summarization algorithms to financial news is still an open research problem. This paper addresses the summarization of collections of financial documents written in different languages to enhance the financial actor's awareness of foreign markets. Specifically, the proposed mining system (i) is able to cope with news written in multiple languages, (ii) generates multiple-level summaries covering specific and high-level concepts in separate sections, on behalf of users with different skill levels, and (iii) ranks the summary content based on both objective and subjective quality indices. These features are taking an increasingly important role in financial data summarization. As a case study, a preliminary implementation of the proposed system has been presented and validated on real multilingual news ranging over stocks of different markets. The preliminary results show the effectiveness and usability of the proposed approach.
Extent of alcohol use and mental health (depressive and post-traumatic stress disorder symptoms) in undergraduate university students from 26 low-, middle- and high-income countries

Objective. To estimate if there is a non-linear association between varying levels of alcohol use and poor mental health (depressive and post-traumatic stress disorder (PTSD) symptoms) in university students from low-, middle- and high-income countries. Methods. Using anonymous questionnaires, data were collected from 19 238 undergraduate university students (mean age 20.8; standard deviation (SD) 2.8) from 27 universities in 26 countries across Asia, Africa and the Americas. Alcohol use was assessed in terms of number of drinks in the past 2 weeks and number of drinks per episode, and measures of depression and PTSD symptoms were administered. Results. The proportion of students with elevated depression scores was 12.3%, 16.9%, and 11.5% for non-drinkers, moderate drinkers, and heavy drinkers, respectively, while the proportion of students with high PTSD symptoms was 20.6%, 20.4% and 23.1% for non-drinkers, moderate drinkers, and heavy drinkers, respectively. Logistic regression found that non-drinkers and heavy drinkers had a lower odds than moderate drinkers to have severe depression, after adjusting for sociodemographic variables, social support and subjective health status. Further, heavy, more frequent drinkers and more frequent binge drinkers had a higher odds to have elevated PTSD symptoms than moderate and non-drinkers, after adjusting for sociodemographic variables, social support and subjective health status. Conclusion. The results suggest a reverse U-shaped association between recent alcohol use volume and frequency and depressive symptoms (unlike that previously identified), and a J-shaped association between binge drinking frequency and depressive symptoms and alcohol use and PTSD symptoms.
American and Australasian Systems in Psychiatry: Crossing the Bridge

Objective: To familiarize Australasian psychiatrists about differences in the psychiatric systems of the United States and Australasia. A secondary objective is to contribute towards a multi-leveled collaboration between the Australian and New Zealand College of Psychiatrists and the American College of Psychiatry and Neurology. Conclusions: There appear to be multiple differences, including in aspects of training, acquiring credentials, cross accreditation, the effect of managed care on clinical practice, volume of research, and interpersonal relations. Despite differences in the systems, it seems critical to anchor oneself to the bio-psycho-social model in order to maintain the integrity of psychiatric practice.
Approximations for the M/G/m Queue

We study the M/G/m queue and obtain difference-differential equations for the equilibrium joint distribution of the number of customers present and of the remaining holding times for services in progress. A study of these equations leads to the proposal of a simple approximation for the queue length distribution. Approximate waiting time and busy period distributions easily follow. Simple expressions for the means of the variables in question are obtained. Some numerical results on the mean waiting time indicate that the proposed approximation is rather accurate. The technique presented in this paper can also be applied to variants of the M/G/m queue. In particular, a short treatment of the queue with finite waiting room is included.
Approximations of the Mean Waiting Time in an M/G/s Queueing System

This paper considers the problem of obtaining approximate expressions for the first moment WGs of the stationary waiting time distribution in an M/G/s queueing system. Special attention is paid to the case G ≡ D, i.e., constant service times. Most known approximations are in fact heavy traffic approximations which have rather large relative errors in the light traffic case. In the present study both the light traffic and heavy traffic behavior of WGs (WDs) are taken into account. In order to obtain mean waiting time approximations it appears to be useful to introduce a quantity (the “normed cooperation coefficient”) which is inversely proportional to WGs and which is in some sense a measure for the “cooperation” between the servers of the service facility. A part of the paper is devoted to the analysis of this normed cooperation coefficient.
Equilibrium Linear Bidding Strategies

Symmetric bidding models are considered in which all bidders start with the same prior distribution on the value of the subject of the auction. In addition, each bidder is assumed to develop his own independent estimate. Each bidder's strategy must be a preselected linear function of his estimate. Closed form expressions are obtained for equilibrium sets of such strategies and the resulting expected profit to each bidder when the estimates are drawn from a Weibull distribution. These equilibrium linear strategies approach equilibrium multiplicative strategies as the estimating accuracy improves relative to the common prior information.
Uso de plaguicidas inhibidores de acetilcolinesterasa en once entidades territoriales de salud en Colombia, 2002-2005

Introduccion. Por ser los plaguicidas anticolinesterasicos una causa importante de intoxicacion y de muerte por intoxicacion en los paises en via de desarrollo, el Instituto Nacional de Salud implemento el Programa de Vigilancia Epidemiologica de Organofosforados y Carbamatos, del cual, este informe corresponde al periodo 2002-2005. Objetivo. Determinar la actividad de la acetilcolinesterasa en participantes con riesgo de exposicion a plaguicidas organofosforados y carbamatos, e identificar los plaguicidas mas utilizados en el area estudiada. Materiales y metodos. Es un estudio descriptivo de informacion reportada al Programa de Vigilancia Epidemiologica de Organofosforados y Carbamatos por once departamentos colombianos, los cuales realizaron la determinacion de acetilcolinesterasa con el equipo Lovibond. Resultados. Participaron 28.303 personas con riesgo de exposicion a plaguicidas; 81,4% eran hombres. El 9,3% de las determinaciones analiticas fueron anormales, con una prevalencia de anormalidad entre los hombres de 9,9% y de 7,0% en las mujeres. Presentaron mayor prevalencia de valores anormales los grupos de edad de 18 a 25 anos (12,3%) y de 0 a 5 anos (10,7%), y los oficios de jornalero (27,0%) y servicios generales del campo (26,1%). De los 975 participantes, en el departamento del Meta, 80% de los participantes presentaron niveles anormales de actividad de la enzima. Los plaguicidas mas reportados fueron los organofosforados (39,7%) y carbamatos (16,6%). Conclusion. El incremento en la prevalencia de valores anormales de la acetilcolinesterasa y el riesgo de exposicion infantil, hacen necesario disminuir el uso y la comercializacion de plaguicidas de alto riesgo, y utilizar metodos menos toxicos para el control de plagas.
Capacity Expansion when Demand Is a Birth-Death Random Process

When demand is assumed to be a birth-death process, and capacity expansion costs are assumed to occur instantaneously at the time of expansion, it is shown that an “equivalent” deterministic-demand problem can readily be generated. The derived problem is equivalent in the sense that its solution by ordinary deterministic capacity expansion methods would also yield the solution of the stochastic problem. It is shown that the “equivalent deterministic demand” is always greater than the “expected demand,” where the latter is defined by the expected time to first reach various levels of demand, and is not the expected number of customers. In addition to general formulas for the discrete-customer case, equations are also derived for the “equivalent deterministic demand” when demand is based on a diffusion process.
Hard Knapsack Problems

We consider a class of algorithms which use the combined powers of branch-and-bound, dynamic programming and rudimentary divisibility arguments for solving the zero-one knapsack problem. Our main result identifies a class of instances of the problem which are difficult to solve by such algorithms. More precisely, if reading the data takes t units of time, then the time required to solve the problem grows exponentially with the square root of t.
Imperfect Competition in the International Energy Market: A Computerized Nash-Cournot Model

This paper describes the conceptual structure, properties, and solution approach of a computerized model of the international energy market. The model treats energy producers as players in a multistage, noncooperative game. The goal of each player (or cartel of players) is assumed to be maximization of discounted profit subject to technical, political, and resource constraints. The model calculates that collection of intertemporal extraction and price paths from which a player can unilaterally deviate only at a loss---the open-loop, Nash equilibrium. The model integrates the theory of exhaustible resources due to Hotelling and the theory of oligopoly due to Nash and Cournot. Although useful as a teaching device to illustrate theoretical results, its main function is to facilitate analysis of real-world resource problems. The model is flexible, allowing the user to specify not only cost, demand and reserve information but also assumptions about who belongs to what coalition. Two shortcomings deserve note. The strategies of players are restricted to time-dated (open-loop) paths. Also, lags cannot be accommodated in the current version. The restriction of the strategy space significantly increases tractability and will permit the incorporation of lags and other complications in the future. The model was built under government contract and is in the public domain.
The use of e‐mail in the identification of bulimia nervosa and its treatment

Despite the great potential of new technologies, no systematic study of e-mail therapy for subjects with eating disorders has been published. We recruited, using a single announcement made via e-mail, from all 20 000 staff and students of a large college of the University of London, 23 individuals (all female) who appeared to fulfil diagnostic criteria for Bulimia Nervosa or Binge Eating Disorder (DSM IV). These women were offered on-line therapy by one of two clinicians experienced in the treatment of eating disorders. At 3-month follow-up, 19 returned questionnaires and showed significant reductions in outcome scores. Significant correlations were found between word count, a measure of engagement with treatment, and outcomes. This pilot study suggests that the Internet may be a useful way to recruit and treat those with eating disorders. A randomized controlled trial is indicated.

Eyes wide open? eyelid location and eye aperture estimation for pervasive eye tracking in real-world scenarios

Eyelid identification and aperture estimation provide key data that can be used to infer valuable information about a subject's mental state (e.g., vigilance, fatigue, and drowsiness) as well as validate or reduce the search space of other eye features. In this paper, we consider these tasks from the perspective of pervasive eye tracking, taking into account the multiple challenges and constraints that arise from this scenario. A novel method for eyelid identification and aperture estimation is proposed and evaluated against challenging data from an eye-tracking experiment conducted in driving scenarios in the wild. The proposed method outperforms an state-of-the-art approach by up to 40 percentage points and runs in real-time on state-of-the-art eye tracking systems. The method implementation and the realistic dataset are provided openly at www.ti. uni-tuebingen.de/perception.
Nonvirally Engineered Porcine Adipose Tissue‐Derived Stem Cells: Use in Posterior Spinal Fusion

Multiple factors alter intervertebral disc volume, structure, shape, composition, and biomechanical properties, often leading to low back pain. Spinal fusion is frequently performed to treat this problem. We recently published results of our investigation of a novel system of in vivo bone formation, in which we used nonvirally nucleofected human mesenchymal stem cells that overexpress a bone morphogenetic protein gene. We hypothesized that primary porcine adipose tissue‐derived stem cells (ASCs) nucleofected with plasmid containing recombinant human bone morphogenetic protein‐6 (rhBMP‐6) could induce bone formation and achieve spinal fusion in vivo. Primary ASCs were isolated from freshly harvested porcine adipose tissue. Overexpression of rhBMP‐6 was achieved ex vivo by using a nucleofection technique. Transfection efficiency was monitored by assessing a parallel transfection involving an enhanced green fluorescent protein reporter gene and flow cytometry analysis. rhBMP‐6 protein secreted by the cells was measured by performing an enzyme‐linked immunosorbent assay. Genetically engineered cells were injected into the lumbar paravertebral muscle in immunodeficient mice. In vivo bone formation was monitored by a quantitative microcomputed tomography (μCT). The animals were euthanized 5 weeks postinjection, and spinal fusion was evaluated using in vitro μCT and histological analysis. We found formation of a large bone mass adjacent to the lumbar area, which produced posterior spinal fusion of two to four vertebrae. Our data demonstrate that efficient bone formation and spinal fusion can be achieved using ex vivo, nonvirally transfected primary ASCs. These results could pave the way to a novel biological solution for spine treatment.
Canonical Wnt Signaling Controls Proliferation of Retinal Stem/Progenitor Cells in Postembryonic Xenopus Eyes

Vertebrate retinal stem cells, which reside quiescently within the ciliary margin, may offer a possibility for treatment of degenerative retinopathies. The highly proliferative retinal precursor cells in Xenopus eyes are confined to the most peripheral region, called the ciliary marginal zone (CMZ). Although the canonical Wnt pathway has been implicated in the developing retina of different species, little is known about its involvement in postembryonic retinas. Using a green fluorescent protein‐based Wnt‐responsive reporter, we show that in transgenic Xenopus tadpoles, the canonical Wnt signaling is activated in the postembryonic CMZ. To further investigate the functional implications of this, we generated transgenic, hormone‐inducible canonical Wnt pathway activating and repressing systems, which are directed to specifically intersect at the nuclear endpoint of transcriptional Wnt target gene activation. We found that postembryonic induction of the canonical Wnt pathway in transgenic retinas resulted in increased proliferation in the CMZ compartment. This is most likely due to delayed cell cycle exit, as inferred from a pulse‐chase experiment on 5‐bromo‐2′‐deoxyuridine‐labeled retinal precursors. Conversely, repression of the canonical Wnt pathway inhibited proliferation of CMZ cells. Neither activation nor repression of the Wnt pathway affected the differentiated cells in the central retina. We conclude that even at postembryonic stages, the canonical Wnt signaling pathway continues to have a major function in promoting proliferation and maintaining retinal stem cells. These findings may contribute to the eventual design of vertebrate, stem cell‐based retinal therapies.
Native Hawaiian Male Caregivers: Patterns of Service Use and Their Effects on Public Policies

The purpose of this study is to compare and contrast the effects of caregiving for Native Hawaiian males, as compared to Asian and Caucasian males, and to determine how these differences affect service use patterns and opinions on government policies. Using a survey instrument adapted from a national data collection effort, data were collected from a probability sample of 600 caregivers in Hawai‘i, of which 155 were male. Analysis was limited to the 148 male caregivers with ethnicity data: Native Hawaiians (N=36), Caucasians (N=50), and Asians (N=62). Findings indicate that of the three groups studied, Native Hawaiians were the least burdened by caregiving. They were most likely to use training services and transportation, but did not generally use formal services because services were either unavailable or cost too much. Native Hawaiians were also most likely to express the need for overnight respite, tax relief, and paid family leave. The findings highlight the importance of gender and culture in the way caregiving services and policies are offered.
