Ansiedade e depressao entre homens e mulheres submetidos a intervencao coronaria percutanea

A descriptive, cross-sectional, correlational study aimed to investigate the association of sex and the presence of anxiety and depression after hospital discharge in patients who underwent percutaneous coronary intervention (PCI). Fifty-nine patients undergoing PCI and receiving outpatient treatment in the first seven months after hospital discharge were evaluated. To assess the symptoms of anxiety and depression the Hospital Anxiety and Depression Scale (HADS) was used. To test the possible associations between the variables anxiety, depression and sex the Chi-square test was used with a significance level of 5%. The results indicated a greater number of women with depression and the association between the variables sex and depression was statistically significant. In relation to anxiety, cases were more frequent in males and the association between the variables sex and anxiety was not statistically significant.
Demonstration of Thiopurine Methyltransferase Activity in the Erythrocytes of Cats

Azathioprine is a purine analogue used as an immunosuppressive and immunomodulator agent in various mammals, including cats. Several adverse reactions have been reported and have limited the use of the drug in the cat. Adverse reactions to azathioprine in humans have been correlated with reduced activity of thiopurine methyltransferase (TPMT) in erythrocytes. The purpose of this preliminary study was to determine if cats have TPMT activity in their erythrocytes and to compare the values obtained with the normal range for humans and the normal range for dogs in a preliminary report. Activity of the enzyme was measured in blood samples drawn from 41 cats. Blood also was taken from 5 dogs. The mean erythrocyte TPMT activity in the cats was 2.4 +/- 0.4 nmol (range, 1.2-3.9 nmol) per hour per milliliter of red blood cells (U/mL RBC) or 2-8 nmol per hour per gram of hemoglobin (U/g Hb). This range was far lower than the normal human range (8-15 U/mL RBC; 16-33 U/g Hb) and was of monopolar distribution. This observation apparently precludes any diagnostic purpose in assaying erythrocyte TPMT in this species. Erythrocyte TPMT activity in the 5 dogs ranged from 5.5 to 13.1 U/mL RBC (11-27 U/g Hb), which was comparable with normal and carrier ranges for humans, but proof of TPMT genetic polymorphism in either species will require genotyping studies.
Temporal Logic Based Hierarchical Test Generation for Sequential VLSI Circuits

Test generation for sequential VLSI circuits has remained a difficult problem to solve. The difficulty arises because of reasoning about temporal behavior of sequential circuits. We use temporal logic to model digital circuits. Temporal Logic can model circuits hierarchically. A set of heuristics is given to aid during test generation. A hierarchical test generation algorithm is proposed.
Endothelial Dysfunction in Passive Smokers

Nowadays, there is no doubt that exposure to passive smoking, whatever it may be approached to be studied - and there are a lot of study approaches: clinical, biological, metabolic, epidemiologic, statistic and so on, that recognize different pathogenetic mechanisms of damage- leads to only one final result that is a reversibly functional harm of the heart and blood vessels following acute exposure, and pathologic alterations that become, in the long run, irreversible lesions of the above target organs after chronic exposure. The harm of the heart and blood vessels from passive smoking is the result of either an isolated action or combined action of some toxics contaminated indoor air by tobacco products, primarily nicotine and carbon monoxide. Among the different types of vessel damage caused by acute exposure to passive smoking, there is evidence that endothelial dysfunction, characterized by impaired endothelium- dependent vasodilation as a result of reduced nitric oxide (NO) production, is the earlier alteration to appear, although, initially, is transient but repeatable.

Minimized Stock Forecasting Features Selection by Automatic Feature Extraction Method

This paper presents a methodology to 1-day-forecast stock index using the automatic feature extraction method based on the neural network with weighted fuzzy membership functions (NEWFM). The distributed non-overlap area measurement method selects the minimized number of input features by automatically removing the worst input features one by one. CPP(Current Price Position of the day n: a percentage of the difference between the price of the day n and the moving average from the day n-1 to the day n-m) and the 2 wavelet transformed coefficients from the recent 32 days of CPP are selected as minimized features using bounded sum of weighted fuzzy membership functions (BSWFMs). For the data sets, from 1989 to 1998, the proposed method shows that the forecast rate is 60.93%.
Heuristic approach to dynamic motion planning for multi-link planar manipulators in a sparse, time varying environment

In this paper a fast and simple method to solve the motion planning problem for planar manipulators is suggested. This method is based on the development of a set of simple reactive behaviours, which allow the robot to move through a time-varying workspace. These simple reactive behaviours are activated by each link of the robot in response to the sensory information experienced as the robot moves through its workspace in search of its goal. As a consequence of the robot's behaviours being reactive, the influence of obstacles on the robot's path is only local. However, there is a subset of problems for which sequential movement of links fails to guide the robot to its goal. This constitutes what we describe as a local minima problem. This problem has been solved by producing a behaviour which identifies local minima and defines an intermediate goal for the robot, in order to guide it out of the local minima. Results are given in the paper which illustrate the performance of this planner.
Comparisons of Mach distributed performance using the WPI Benchmark Suite

A set of programs, the WPI Benchmark Suite (WBS), was developed with the specific objective of comparing the performances of Unix-like operating systems running on identical hardware platforms. Performance results from running parts of the WBS under Mach 2.5, Mach 3.0, and SunOS 4.1. 1 on HP 386 PCs, HP 486 PCs, and Sun 3/60 workstations are presented. The focus is on the WPI benchmarks designed to evaluate the effectiveness of different operating system mechanisms for distributed applications. The results identify strengths and weaknesses of these operating systems. The results show that Mach 3.0 does not perform as well as Mach 2.5 on benchmarks involving network communications or local socket communication. Mach 3.0 does outperform Mach 2.5 on a benchmark which involves extensive disk input/output (I/O). The Jigsaw benchmark demonstrates that Mach 3.0 has difficulty with heavy paging activity. Additionally, SunOS 4.1. 1 performs better that Mach 2.5 for certain interprocess communication methods. <<ETX>>
Facebook enhances antidepressant pharmacotherapy effects.

Treatment-resistant major depressive disorder (TR-MDD) is a complex condition, with very low remission rates. In recent years some studies have been conducted on the implementation of cognitive behavioral therapy and psychodynamic psychotherapy interventions via the Internet to MDD patients, and results have been promising. However, there have been no studies in patients with TR-MDD nor with the use of Facebook with the psychiatrist as “friend. ” 60 TR-MDD patients were randomized to one of three groups: Facebook group with psychiatrist as “friend,” Facebook group without psychiatrist as “friend,” and control group (no Facebook use). Both Facebook groups spent at least 1 hour/day on Facebook, 7 days/week, during the 3 months. All patients maintained their usual pharmacotherapy. All participants were evaluated at baseline and at 1, 2, and 3 months for depressive symptoms using HAD17 and BDI-II. Results show that both Facebook groups had a decrease on HADM17 and BDI-II scores as well as higher remission and response rates than the control group, with better results if the psychiatrist was a “friend” on Facebook. Therefore, in TR-MDD, Facebook can be used as an effective enhancement therapy, adjuvant to pharmacological therapy with regular consultations, especially if the psychiatrist is the patient's online “friend. ”
Publication in College & Research Libraries: Accepted, Rejected and Published Papers, 1980-1991

The authors examine characteristics of authorship, editorial decisions, and reviewer assessments for accepted and rejected papers for College & Research Libraries (C&RL) based on over a decade of internal records (private correspondence and reviewer assessments) made available to them. Noting the wider literature dealing with publishing in refereed journals, this study makes comparisons to that literature and suggests directions for future research. The authors found that C&RL editors and reviewers conducted their work without major disagreement or rancor. Refereeing has indeed served the journal's readership well
Assessment Within the Augustana Model of Undergraduate Discipline-Specific Information Literacy Credit Courses

SUMMARY Augustana (located in Camrose, Alberta, Canada, and formerly known as Augustana University College) is an undergraduate liberal arts and sciences faculty of the University of Alberta with an enrollment of approximately 1,100 students. The fall of 2001 marked the inception of for-credit discipline-specific information literacy (IL) course offerings at Augustana. At that time, Augustana librarians began teaching two IL courses that were required for graduation for students in the relevant degrees (Bachelors of Music, Arts in Music, and Arts in English). Since that time, for-credit discipline-specific IL courses have been added in nineteen disciplines, bringing Augustana's total number of IL courses to twenty-one. This paper will give an overview of the development and implementation of these IL courses and will focus on the assessment practices to date. Specifically, data gathered from pretests and post-tests will be analyzed and results from a separate follow-up survey conducted of current students and graduates will be reviewed. In addition, an in-house Web-based assessment tool will be introduced and discussed.
Volume compression of MRI data using zerotrees of wavelet coefficients

Volume data such as those acquired by magnetic resonance imaging techniques can be compressed efficiently using the wavelet transform. Wavelet compression methods need to retain both the value and the location of the significant coefficients. We present experimental results demonstrating the use of zerotree encoding methods in wavelet compression can enhance the ability to further compress volume data.
A Validation of Brief Tests of Collection Strength

Abstract The purpose of this study was to assess the validity of the brief test methodology developed by Howard White for collection evaluation. Using White's methodology, two brief tests in Soviet history were developed and applied to five different libraries. Then, the results of the two tests were examined and compared with each other, with the results of a previous brief test in Russian/Soviet history, and with self-evaluations by a number of the tested libraries. The conclusions strongly support White's claims for the validity of brief test methodology.
An integrated model of the human ventilatory control system: the response to hypoxia

This work presents a mathematical model of the human respiratory control system, based on physiological knowledge. It includes three compartments for gas storage and exchange (lungs, brain tissue and other body tissues), and various kinds of feedback mechanisms. These comprehend peripheral chemoreceptors in the carotid body, central chemoreceptors in the medulla and a central ventilatory depression. The latter acts by reducing the response of the central neural system to the afferent peripheral chemoreceptor activity during prolonged hypoxia of the brain tissue. Furthermore, the model considers local blood flow adjustments in response to O2 and CO2 arterial pressure changes. In this study, the model has been validated by simulating the response to square changes in alveolar PCO2, performed at different constant levels of alveolar PO2. A good agreement with data reported in the literature has been checked. Subsequently, a sensitivity analysis on the role of the main feedback mechanisms on ventilation response to CO2 has been performed. The results suggest that the ventilatory response to CO2 challenges during hyperoxia can be almost completely ascribed to the central chemoreflex, while, during normoxia, the peripheral chemoreceptors provide a modest contribution too. By contrast, the response to hypercapnic stimuli during hypoxia involves a complex superimposition among different factors with disparate dynamics. Hence, results suggest that the ventilatory response to hypercapnia during hypoxia is more complex than that provided by simple empirical models, and that discrimination between the central and peripheral components based on time constants may be misleading.
Analyzing the impact of elaborated worked example modeling in a computer simulation for promotion of schema acquisition

Worked examples have been effective in enhancing learning outcomes, especially with novice learners. Most of this research has been conducted in laboratory settings. The purpose of this study was to evaluate the impact of embedding elaborated worked example modeling in a computer simulation practice activity, within a classroom environment. The benefits derived from this study are the acquisition of empirical data that helps determine the value of embedding elaborated worked example modeling as a learning support within computer simulation activities. The data also help to determine if this is a valuable enhancement of the active learning provided by interactive computer simulations, which have already been proven effective in increasing academic achievement.
Motivating staff in Nigerian university libraries

Reports on a survey conducted to investigate the level of motivation among librarians and para‐professional staff in Nigerian university libraries using the questionnaire method to elicit the necessary data. Major variables considered are: training opportunities, frequency of development, work environment, promotion prospects, sabbatical leave, communication and management style. Also attempts a brief definition of motivation and examines the views of a few classical writers on the subject. Reveals a general dissatisfaction with all the variables but one, i.e. frequency of development. All the respondents agreed with the frequency of development of staff in their respective libraries. Suggests some practical ways of motivating staff. Chief among these is the management style of university librarians going out to see for themselves what is going on in the various sections of the libraries. By this, university librarians will be able to observe their staff at work, talk to them in their various offices on a regular basis and be able to carry out on‐the‐spot assessment, listen and praise staff as the case may be.
A successive interference cancellation scheme for an ODFM system

We consider an orthogonal frequency division multiplexing (OFDM) system with successive interference cancellation to reduce interchannel interference. The system operates in a Rayleigh frequency selective channel and pilot symbols are inserted in each OFDM frame for the purpose of channel estimation. Interchannel interference (ICI) is caused by the time variations in the channel gain within one OFDM frame. The ICI leads to an error floor, which is a function of the Doppler frequency. It was found that by performing successive interference cancellation at the receiver, we were able to significantly reduce the error floor caused by ICI. Furthermore, we introduce a simple channel estimator based on pilot symbols to estimate the multipath fading channel information required to perform the SIC.
Models and Algorithms for Private Data Sharing

In recent years, there has been a tremendous growth in the collection of digital information about individuals. Many organizations such as governmental agencies, hospitals, and financial companies collect and disseminate various person-specific data. Due to the rapid advance in the storing, processing, and networking capabilities of the computing devices, the collected data can now be easily analyzed to infer valuable information for research and business purposes. Data from different sources can be integrated and further analyzed to gain better insights. On one hand, the collected data offer tremendous opportunities for mining useful information. On the other hand, the mining process poses a threat to individual privacy since these data often contain sensitive information. In this thesis, we address the problem of developing anonymization algorithms to thwart potential privacy attacks in different real-life data sharing scenarios. In particular, we study two privacy models: LKC-privacy and differential privacy. For each of these models, we develop algorithms for anonymizing different types of data such as relational data, trajectory data, and heterogeneous data. We also develop algorithms for distributed data where multiple data publishers cooperate to integrate their private data without violating the given privacy requirements. Experimental results on the real-life data demonstrate that the proposed anonymization algorithms can effectively retain the essential information for data analysis and are scalable for large data sets.

Clinical Profile and Outcome of Japanese Encephalitis in Children Admitted with Acute Encephalitis Syndrome

Japanese encephalitis (JE) is an arthropod borne viral disease. Children are most commonly affected in Southeast Asian region showing symptoms of central nervous system with several complications and death. The clinical characteristics and outcomes in pediatric JE patients hospitalized with acute encephalitis syndrome (AES) are still poorly understood. A prospective study was conducted in pediatric ward of Assam Medical College Hospital to evaluate the clinical profile and outcome of JE in children. A total of 223 hospitalized AES cases were enrolled during March to December 2012. Serum and cerebro spinal fluids were tested for presence of JE specific IgM antibody. 67 (30%) were found to be JE positive. The most common presenting symptoms in JE patients were fever (100%), altered sensorium (83.58%), seizure (82.08%), headache (41.79%), and vomiting (29.85%). Signs of meningeal irritation were present in 55.22% of cases. Around 40.29%, JE patients had GCS ≤ 8. Among the JE patients, 14.7% died before discharge. The complete recoveries were observed in 63.9% of cases, while 21.3% had some sort of disability at the time of discharge. JE is still a major cause of AES in children in this part of India. These significant findings thus seek attentions of the global community to combat JE in children.
Teacher’s use of iPads in higher education

Mobile devices (e.g. iPads or galaxy tab) are increasingly being used in educational contexts. There has been growing investment in higher education institutions in Hong Kong by the HKSAR Education Bureau in relation to educational uses of mobile technology. However, current research into educational applications of this technology is limited. This article reports results of a qualitative study that investigated how higher education teachers use iPads to facilitate their practice. The study results provide insight into both the educational affordances of iPad technology and the ways in which teachers’ personal or private theories mediate these affordances. The study outcomes contribute to theoretical understanding of higher education teacher changes through adoption of mobile technology. Furthermore, the outcomes provide a set of recommendations for applications of iPads and similar technologies in higher education and ways to support teachers to effectively adopt such technology in their practices.
Ultra Low-Power Biomedical Signal Processing: An Analog Wavelet Filter Approach for Pacemakers

Often WT systems employ the discrete wavelet transform, implemented on a digital signal processor. However, in ultra low-power applications such as biomedical implantable devices, it is not suitable to implement the WT by means of digital circuitry due to the relatively high power consumption associated with the required A/D converter. Low-power analog realization of the wavelet transform enables its application in vivo, e.g. in pacemakers, where the wavelet transform provides a means to extremely reliable cardiac signal detection. In Ultra Low-Power Biomedical Signal Processing we present a novel method for implementing signal processing based on WT in an analog way. The methodology presented focuses on the development of ultra low-power analog integrated circuits that implement the required signal processing, taking into account the limitations imposed by an implantable device.
Probability or frequency? Expressing forecast uncertainty in public weather forecasts

Is uncertainty expressed as frequency easier for non‐experts to understand than uncertainty expressed as probability? The experiment reported here compared participants' responses to the same wind speed forecast expressed several different ways. Three different uncertainty expressions were tested (90%, 9 times in 10, or 90 out of 100%). Also tested was whether understanding was improved by including a short phrase explaining, in lay terms, how the forecast was derived (adding a reference class). Results suggested that, contrary to prior research, participants better understood the forecast when it was presented in a probability format rather than a frequency format. Furthermore, specifying a reference class did not facilitate understanding. Copyright © 2009 Royal Meteorological Society
