BACKGROUND The burden of obesity in Vietnam has not been well defined because there is a lack of reference data for percent body fat (PBF) in Asians. This study sought to define the relationship between PBF and body mass index (BMI) in the Vietnamese population. METHODS The study was designed as a comparative cross-sectional investigation that involved 1217 individuals of Vietnamese backgroun...
heuristics are often used to provide solutions for flow shop scheduling problems.the performance of a heuristic is usually judged by comparing solutions and run times on test cases.this investigation proposes an analytical alternative ,called asymptotic convergence ,which tests the convergence of the heuristic to a lower bound as problem size grows. the test is a stronger variation of worst cas...
A recently introduced impulse postfix OFDM (IPOFDM) system achieves the enhanced bit error rate (BER) performance compared to that of conventional OFDM systems, but there is an important peak-to-average power ratio (PAPR) issue of using impulse postfix (IP) that needs to be resolved. This paper proposes a combined IP-OFDM scheme with the selected mapping technique and the optimum power boosting...
The objective of the present study was to evaluate the predictive values of percent body fat (PBF) and body mass index (BMI) for cardiovascular risk factors, especially when PBF and BMI are conflicting. BMI was calculated by the standard formula and PBF was determined by bioelectrical impedance analysis. A total of 3859 ambulatory adult Han Chinese subjects (2173 males and 1686 females, age ran...
One of the strengths of PBF is its flexibility. Adherents to PBF continuously seek improvements in theory, best practice and instruments. The contributions of Ireland et al.1 and Kalk2 in response to the excellent paper from Meessen et al.3 are therefore welcome. However, some of their points of criticism are based on misunderstandings and they transpose assumptions about behaviour in high-inco...
BACKGROUND Although estimation of percentage body fat with the Slaughter skinfold-thickness equations (PBF(Slaughter)) is widely used, the accuracy of this method has not been well studied. OBJECTIVE The objective was to determine the accuracy of the Slaughter skinfold-thickness equations. DESIGN We compared agreement between PBF(Slaughter) and estimations derived from dual-energy X-ray abs...
Over the past 15 years, performance-based financing has been implemented in an increasing number of developing countries, particularly in Africa, as a means of improving health worker performance. Scaling up to national implementation in Burundi and Rwanda has encouraged proponents of performance-based financing to view it as more than a financing mechanism, but increasingly as a strategic tool...
abstract the present study was conducted to examine the effect of proficiency on students interaction while carrying out the grammar-based task(s) in collaboration. in particular, the study examines whether the level of proficiency affects the learners’ focus of attention to grammatical and lexical features. the study takes a further step and examines whether there is any difference in the use...
BACKGROUND Physiological measures per lung parenchyma, rather than per lung volume, sometimes reflect the disease status. PET images of the lung, which are usually expressed per lung volume, could confound the interpretation of the disease status, especially in cases with a prominent heterogeneity in aeration. The aim of the present study was to develop a method for measuring pulmonary blood fl...
