BACKGROUND The prevalence of overweight and underweight is steadily increasing among children and adolescents. To explore the relationship between parental socioeconomic status and body mass index, we examined levels of overweight and underweight among representative samples of children and adolescents in South Korea. METHODS We analyzed data from the 2009 Korean Survey on the Obesity of Yout...

Purpose: To identify beliefs held by the general public regarding causes of weight gain, weight prevention strategies, and barriers to weight management; and to examine whether such beliefs predict the actual body mass of participants. Methods: A questionnaire-based survey was administered to participants recruited from regional and metropolitan areas of Australia. This questionnaire obtained d...

Crested wheatgrass (Agropyron cristatum (L.) Gaertner.) is a potential source of low-maintenance turf species for use in areas with less water. The main goal of this study was to evaluate turf quality characteristics of 24 crested wheatgrass specimens collected from different locations of Iran as low-maintenance turfgrass. The experimental design was a randomized complete block design with 3 re...

 ABSTRACT Background: Aspirin even at low dose ( 100 mg) can increase the risk of upper gastrointestinal bleeding. It is usual to use low dose aspirin for cardiovascular prophylaxis. We hypothesized that Helicobacter pylori eradication is as effective as omeprazole maintenance therapy for secondary prevention of bleeding in those who take low dose aspirin and are positive for Helicobacter pylor...

There has been a resurgence of interest in index maintenance (or incremental indexing) in the academic community in the last three years. Most of this work focuses on how to build indexes as quickly as possible, given the need to run queries during the build process. This work is based on a different set of assumptions than previous work. First, we focus on latency instead of throughput. We foc...

Recent P2P systems, represented by Oceanstore and PAST, offer an administration-free and fault-tolerant storage utility. Nodes in these systems collectively contribute towards a storage space, in a self-organizing fashion. While elegant from a theoretical perspective, they can be improved in three important areas: (i) low maintenance cost; (ii) the ability to make discriminative use of the node...
