Because first graders are critical for excess weight gain, we assessed components of the metabolic syndrome (MetS) using the pediatric definition of the International Diabetes Federation (IDF). We compared four MetS components as defined by the IDF with age- and gender-specific components in 2228 first graders at the age of 6. The growth curves were derived from 22113 children and adolescents w...
In this paper, we describe our Question Answering System. We proposed to use 200 answer types to abate answer types’ ambiguity in Query Analysis. And as the score of extracting correct answers, we proposed TF・IDF and a word distance between an answer candidate and a weighty word from a query. Comparative experiments were conducted with QAC1 and QAC2 formal run test set. The result showed that 2...
OBJECTIVE Metabolic syndrome increases the risk for type 2 diabetes and cardiovascular disease (CVD) and may be associated with insulin resistance. RESEARCH DESIGN AND METHODS We tested the hypothesis that the metabolic syndrome confers risk with or without concomitant insulin resistance among 2,803 Framingham Offspring Study subjects followed up to 11 years for new diabetes (135 cases) or CV...
Keyword extraction has received an increasing attention as important research topic which can lead to have advancements in diverse applications such document context categorization, text indexing and classification. In this paper we propose STF-IDF, a novel semantic method based on TF-IDF, for scoring word importance of informal documents corpus. A set nearly four million from health-care socia...
BACKGROUND The aim of this study is to investigate the cardio-metabolic parameters and surrogate markers of insulin resistance in a discordant group of type 2 diabetes (T2DM) subjects who satisfy the Adults Treatment Panel (ATP) III criteria, but not the International Diabetes Federation (IDF) criteria, for metabolic syndrome (MetS). METHODS We assessed the prevalence of MetS in T2DM subjects...
The Integrate-and-Dump Filter (IDF) is used as a matched filter for the detection of signals in additive white Gaussian noise. In this article, the performance of the digital integrateanddump filter is evaluated. The case considered is when symbol times are known and the sampling clock is free running at a constant rate, i.e., the sampling clock is not phase locked to the symbol clock. Degradat...
The metabolic syndrome is a constellation of interrelated abnormalities, including dyslipidemia, elevated blood pressure and glucose, and prothrombotic and proinflammatory states (1). Because of the growing prevalence of the metabolic syndrome, several organizations have attempted to set forth clinical criteria for its diagnosis (1–5). The most recent are those proposed by the International Dia...
BACKGROUND During last decade the metabolic syndrome has been defined by five different guidelines. Discrepancies in such definitions could influence syndrome predictive ability over cardiovascular diseases. The aim of this study was to determine the degree of agreement between these five guidelines, in population from Cartagena (Colombia). METHODS A cross sectional study was conducted in adu...
BACKGROUND Metabolic Syndrome is associated with increased risk for type 2 diabetes and cardiovascular diseases. However, different diagnostic criteria have been recommended by different expert groups. In Malaysia, there is a lack of research comparing these different diagnostic criteria. Therefore, it is our aim to study the concordance between the IDF and the modified NCEP ATP III definitions...
This paper investigates several techniques for spoken document retrieval, toward improvement of retrieval performance based on the conventional method i.e. TF-IDF. The first approach employs rescaled unigrams of LDA to compute a similarity score. The second technique employs query expansion by web retrieval using Yahoo!API. And the third technique is Prioritized And-operator Retrieval based on ...
